K & E / Keuffel & Esser c. 1907 Twisted Frame Solar Transit w/ Saegmuller Solar Attachment in Original BoxK & E / Keuffel & Esser c. 1907 Twisted Frame # 5076 Solar Transit w/ 5090 Saegmuller Solar Attachment in Original Box  This is a very nice condition Antique Solar Transit.  It is in near mint original condition.  It looks to have hardly ever been used.  The original finish on the box is in like new condition and so is the finish on the instrument itself.  The distinctive looking "twisted frame standards" K & E used on this instrument were only offered for about 10 years or so.  The serial # 13,371 is found on both the box, and the plate of the instrument.  That dates this transit from 1907 according to the charts available at www.surveyhistory.org.  The matte black lacquer finish on the instrument is 98% or better and near pristine noting just a few minor scuffs.  The loupe, plumb bob and more are all present.  It is also fitted with an upgraded guard for the vertical circle.  The vernier scales on the plate have folding brass covers, and there is a jointed arm on one leg to hold a magnifier.  The solar attachment has a mounting platform on the inside of the box on the bottom board.  It is a very snug fit.   Please look at all the pics to see the exceptional condition.

Solar attachments were developed for use in the field to facilitate finding ones location using the sun and horizon much as seamen would do with sextants or octants.  Their use was made necessary where ore deposits would adversely affect the accuracy of a regular compass.  Each surveying instrument maker developed or adapted one or more different designs for use on their instruments.  K & E primarily used the Saegmuller a small telescope like affair named after the inventor.   Other patented versions of solar attachments were named after the inventor of each, such as Burt, Smith, Pearson, and others.  

All motions operate smoothly. The silvered compass face is flawless, and the compass swings north.  Cross hairs are present in both scopes. NO apologies.  This rare & desirable surveying instrument will display very nicely in any number of settings.

Young / K & E TransitYoung / K & E Transit   This antique transit is in nice overall condition.  It is a light duty explorer or preliminary survey size instrument and has a 9" scope.  It is marked both Young and Keuffel & Esser under the glass on the compass face.  K & E bought out the old time maker Young in 1918 and had them continue to produce instruments under their name for several years before phasing them out altogether.  Thus dating this instrument from that period.

All motions are free and smooth.  Good optics w/ crosshairs.  Compass points north.  Nice even patina.  An overall nice piece in nice condition.

K & E / Keuffel & Esser # 5081 1/2 Engineers Mining Transit w/ 5Aux Scope & AttachmentsK & E / Keuffel & Esser # 5081 1/2 Engineers Mining Transit w/ Aux Scope / Tripod & Attachments in Original Box  This is a very nice condition Engineer's Mining Transit.  It is in near mint original condition. The black crinkle finish is 95% or better and near pristine noting just a few minor scuffs.  It looks to have seen little use.  All motions operate smoothly. The silvered compass face is flawless, and the 3 1/2" Gold compass needle swings north.  Cross hairs are present in both scopes. 1 white plastic vernier cover is missing.  NO other apologies. The nice collapsible leg tripod is included as well.

The serial # 124,320 is found on the box, the horizontal plate of the instrument and is on the second scope as well.  That dates this transit from 1952 according to the charts available at www.surveyhistory.org.    The K & E marked loupe, plumb bob, oiler and more are all present. Note how the plumb bob comes apart and is made to hold a second tip.  An unusual  feature that is not seen very often. 

Mining transits were developed for use in mines or places where the user would need to shoot a line where the plate would be in the way.  The scope could be mounted on either the top over the main scope, or on the outboard side.  The counterweight is also present.    

 This graphic, rare & desirable surveying instrument will display very nicely in a mining related collection or a number of other settings.   Very Nice!!

K & E / Keuffel & Esser c. 1919 # 5070 Engineers Mountain & Mining TransitK & E / Keuffel & Esser c. 1919 # 5074 Engineers Mountain & Mining Transit  This style transit with its unusual 3 screw leveling base is very rare. In catalogs it gets an asterisk with explanation that it is only available through special order.   K & E called this style of transit off as "Extra Fine".  The serial # is 38611 dating it from 1920 or so.  The tag on the door says the needle is calibrated for Buenos Aries Argentina.  There is a tag on the box that also indicates it came from South America.  Note that it has 2 auxiliary magnifiers to allow for a more precise reading of the extra fine scales on the different vernier scales. 

All motions and thumbscrews operate smoothly. The silvered compass face is near flawless, and the 3 3/4" compass needle swings north. The black oxidized finish is mostly fine.  All three level bubbles are good and appear to be original. The optics are clear and good.  There are a few minor apologies.  The door on the box has been remounted on the opposite side of the opening.  Not sure why and no apparent reason.  There is one vertical and 2 horizontal crosshairs. One crosshair above the center horizontal crosshair is broken or unattached.  Also, the protective outer cover or guard for the vertical circle / vernier scale is broken.  I see no damage to the wheel itself.  Finally, there is a small dent on the end of the scope as pictured.

This transit is complete with its rare 3 point tripod. (last pic)  Please look at all the pics to see the condition and features.  This rare & desirable surveying instrument will be a highlight of the well rounded surveying instrument collection and will display very nicely in any number of settings.

K & E / Keuffel & Esser Paragon Transit K & E / Keuffel & Esser Paragon Transit   The serial # is 212282 and I believe this transit dates from the late 60s.  The cosmetic condition of the green finish is nice, but dirty / dusty as if it sat outside its box on the job or on display for a long time.  The overall condition is OK. Cross hairs are present, and the optics are good.  All bubbles are full. The compass points north.  All motions are free and smooth but when the plate is turned it sounds like it needs to be lubed.  It turns easily enough, and without binding it is just noisy gritty sounding.   Nice!!

It has a single lever release on the side to turn it into a limited transit to shoot vertical angles.  It would be perfect for the casual user or builder and a better piece of equipment than Home Depot or Lowes peddles these days for more money.

Buff & Buff Mfg. Co. Solar Transit w/ Smith Patent Solar Attachment Buff & Buff Mfg. Co. Solar Transit w/ Smith Patent Solar Attachment / Box & Tripod  This Buff & Buff solar transit is in exceptional condition. From the serial #28294 we can surmise this solar transit was manufactured in the 1920's - 1930's.   The Buff & Buff MFG. Co was formed after the breakup of the Buff and Berger company back near the turn of the century. The original firm of Buff & Berger split into two companies with each principal going into business with family members of the same name, hence the company names, Buff & Buff, and Berger & Sons found on those instruments.

The transit has developed a nice even patina on the brass portions. The transits main scope is 9" long which would make this a light mountain size transit.  It has an image erect and the optics are crisp and clear. The 4" silvered compass works properly.  The silvered vertical circle is 4" and has an aux Stadia scale as shown.  All level bubbles are good, and there are 2 striding levels as well.  All motions operate as they should. The serial # on the box and instrument match. Even the leather strap is original and stamped with the serial # 28294. The box is very nice and has nearly all of its original finish. The counterweight is a molded piece of lead that is fitted between the standards on the opposite side in such a way as to save space and allowing the box to be smaller and easier to transport in the field. The original Buff marked fixed leg tripod is included in the price.  Buff Solar Transit

Solar transits were developed so that the user could accurately determine his location in the field without relying on the magnetic compass.  Magnetic deviations would adversely affect a magnetic compass and so they were not an accurate means to determine ones location in many areas. The idea with solar transits was to use the position of the sun and the horizon to determine ones location, much as a sextant or octant would be used to determine ones true location on a boat in open water with no visible reference points. The first patent for a solar transit was granted to Burt in the 1830's but many other variants were developed and patented afterward.

There are a number of different versions of solar attachments that were patented and used on surveying instruments. The Burt solar attachment was used on Gurley, Roach and other instruments.  K & E, Buff, Warren Knight, Fauth and others used the Saegmuller patent attachment.  Saegmuller Solar Attachments were a top mounted scope. (see below)  The Smith Patent Solar Attachment and the Pearson Solar Attachment mounted on the side of the instrument and both are more unusual.

This is is a rare instrument that will display very nicely and be a highlight of any collection of surveying or engineering related instruments.

Buff & Buff Mfg. Co. Solar Transit w/ Saegmuller Solar Attachment Buff & Buff Mfg. Co. Solar Transit w/ Saegmuller Solar Attachment  This Buff & Buff solar transit is in exceptional condition. From the serial #6625 we can surmise this transit was manufactured shortly after the turn of the century.  The Buff & Buff MFG. Co was formed after the breakup of the Buff and Berger company back near the turn of the century. The new company began their serial # at 4000. 

The instrument has a near perfect lacquered finish on the brass portions.  The original solar attachment is nickel plated and has a great contrasting look. The transits main scope is 12" long which would make this an engineer's transit.  It has an image erect and the optics are crisp and clear. The 4" silvered compass works properly.  The silvered vertical circle is 4".  All level bubbles are good.  All motions operate as they should. The serial # on the box and instrument match.

The Burt solar attachment was used on Gurley, Roach and a few other instruments.  K & E, Buff, Fauth, Warren Knight and others used the Saegmuller patent attachment.  As evidenced by the other Buff Solar listed, a buyer could order different style solar attachments of his choice.

This is is a rare surveying instrument that will display very nicely and be a highlight of any collection of engineering related instruments.

A. Lietz San Francisco Mining Transit w/ Secondary Scope in BoxA. Lietz San Francisco Mining Transit w/ Secondary Scope in Box   A large graphic antique mining related surveying instrument with a 11 inch main scope and 7" secondary scope.  This good condition antique mining transit is in its original box and was made by A. Lietz California's premier surveying instrument maker and dealer. The black finish is very nice overall. The compass needle is 3 1/2.  The optics in both scopes is nice.  Lietz instruments are hard to date, but I would think this dates from after the turn of the century and pre WWII.  The box is solid.  Very Nice!!

Mining transits were used in situations where the operator had to shoot down vertical shafts or odd angles. When mounted on the side it projected past the plate to allow the user to shoot along that line.  Different manufacturers used different approaches to solve the problem.  Gurley's number for the secondary scope was #160.  Catalogs of the era show that it could be ordered to mount over the scope as well.  Other manufactures used the same means or slight variations on the theme.  Buff offered a rare version where the main scope could be released and moved into another position further out on the standards above the plate.  There is also a version with a leaning frame to allow for the same effect. They are much harder to find than a standard instrument and make a great display when set up.

George Shilling - Washington DC Surveying TransitGeorge Shilling - Washington DC Surveying Transit  An interesting instrument made by a little known but documented maker who was born in Norway in 1844 and first opened up his own shop in Washington DC in 1875.  There is a short bio on him at the Smithsonian site who own several of his instruments, in Smarts book on Surveying instruments, and some more info at the SurveyHistory.org site.  The info found indicates the government was his best customer, and that he died about the time of WWI. 

The optics are OK, but one of the 3 horizontal crosshairs has broken. That has affected the vertical crosshair.  All the motions are free and move well enough. The level bubble on the plate is broken, the one on the plate is OK.  It came in a box, but it is not original.  For some reason the vertical circle is not marked off in degrees.  The edge is silvered and tarnished, but there is no increment markings on it.  A mystery.  It has a nice patina, and will display nicely as it sits.

Expedition Size Transit w/ Aux. Compass & Tripod Expedition Size Transit w/ Aux. Compass & TripodExpedition Size Transit w/ Aux. Compass & Tripod  This is a super condition rare & unusual miniature antique surveying instrument. The scope on this tiny transit is only 4" long. There are two tags in the lid of the box.  One from the San Francisco maker Lietz and one from Schwalb Hermanos who I believe was a large distributer in South America and also had an office in France. I see no marking on the instrument itself but am confident that it is French or European and not US made.

The aux. compass mounts over the top like a striding level.  Note that West is called off with a O.  Also note the beveled limb on the plate.  The tripod legs are hollow and he extension leg slides up into the larger portion.  A neat design.  The box measures approx. 6" square.  The plumb bob is a two piece affair so that it will stop swinging quicker given the extra weight, I assume.  The optics are good, and crosshairs are present.  A super display piece for the science / technology antique collection or home decor.

This instrument is a clone to the K & E offered above or similar instruments by David White, Berger, or others that are out there.  It is the design instrument I use to have and use for layouts and general work when I was a general contractor.  It served me well. This builders transit / level has a single spring loaded lever release on the side to turn it into a limited transit to shoot vertical angles.  It would be perfect for the casual user or builder and a better piece of equipment than Home Depot or Lowes peddles these days for more money.

Wild Heerbrugg T 16 Theodolite Transit Switzerland Wild Heerbrugg T 16 Theodolite Transit Switzerland    Top of the line in its day.  It looks to be in fine condition.  The literature that came with it indicated it was bought as a gift by a son for his father to use on the ranch property without the son realizing it has an inverted image, and so was traded in for something else more suitable for casual use and then sat on a shelf in the shops storage room for 40 years.

Solar & Mining Attachments for Architects, Engineers, & Surveyor's
Transits & Related Surveying Instruments


Buff & Berger Pearson Patent Solar AttachmentBuff & Berger's Pearson Patent Solar Attachment  The Buff & Berger partnership first appeared in the 1870's and was dissolved in 1898 when both principals opened firms under their own names with the addition of other family members, hence the later instrument maker names Berger & Sons, and Buff & Buff.  That would date this rare Buff & Berger solar attachment as pre 1898.  

Pearson was first granted the patent for this telescopic solar attachment in 1875, and Buff & Berger offered an improved version after 1878.  Also note the handwritten instructions that are glued into the top of the box.  Faded but legible. 

Solar attachments were developed for use in the field to facilitate finding ones location using the sun and horizon much as seafarers would do with sextants or octants.  There use was made necessary when there was a danger of ore deposits affecting the accuracy of a regular compass. Each surveying instrument maker developed or adapted one or more different designs for use on their instruments.  Other patented versions were named after the inventor such as Burt, Smith, Saegmuller, and others.

A nice example of a rare piece that will make an otherwise standard looking instrument into a rare and desirable instrument that display well.

Fredrick Yeiser Patent Altitude InstrumentFrederick Yeiser 1859 Patent Altitude / Meridian Instrument    Frederick Yeiser of Lexington Kentucky was granted a patent for this unusual solar / meridian "altitude instrument" on February 8th 1859. The patent # is 22913 and is titled Altitude Instrument.  In addition to this patent, which can be found on Google, Yeiser was granted at least two other patents having to do with the design of similar solar instruments and finding the meridian or altitude of the sun.  The basic principle is much the same as how a sextant or octant was used for navigation over expanses of water, or as a Burt Patent Solar Instrument which was patented in the 1830's was used in surveying.   This instruments basic design is similar with some notable differences.  One of Yeiser's other patents was issued as an improvement to this one on August 9 1859 of the same year.  That info can be bought up as well, but was trickier to find.  The images for that improved patent more closely resemble this instrument.  

After spending several hours bouncing around the internet I found a similar example of Yeiser's work in the Kentucky Historical Society Collection.    That reference was hard to find as they called their piece a Theodolite and failed to mention the exact patent date.  It is interesting to note that that instrument has a second maker name, being John S. Hougham, a known maker of Solar Compasses wtih an example of his work to be seen at the www.Surveyhistory.org site.

At another site I found info on several of his other inventions, but no further mention of, or examples of, instruments like this.  Fredrick Yeiser was granted a number of other patents including a patent for a rail car coupler, an electric motor, and one for an improvement in eyeglasses or spectacles. Yeiser hailed from Danville KY near Lexington KY. Pictures of the original Yeiser homestead in Danville can also be found.  It appears the family was quite well to do.   

The overall condition of this rare solar instrument is exceptional.  The base measures approx. 9" leg to keg of  the tripod base.  It stands approx. 10" tall.  The dial on top is inscribed with the patentees name, Yeiser and the February 8th 1859 Patent date.  It is also inscribed Sturm, Steffens & Co. Indianapolis Ind. who research reveals were the makers.  They were an obscure Mathematical Instrument maker based in Indiana.  I found a listing for them in an old pre Civil War directory which stated

"H. STURM. - C. W. STEFFENS - E. F. STEFFENS. STURM, STEFFENS & CO., MATHEMATICAL QPTICAL & PHILOSOPHICAL INSTRUMENT MAKERS, And Manufacturers of F. Yeiser's Patent Solar Chronometers, No. 8 BLACKFORD'S BUILDING, South-East corner Washington & Meridian Sts., INDIANAPOLIS, IND. All Kinds of Small Machinery, Models, neatly done."

A graphic and near unique museum quality piece that will be the highlight of any collection.
