Keuffel & Esser / K & E Transits



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 scale 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 mining 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 model and 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 cracked. I see no damage to the wheel itself. Finally, there is a small dent on the end of the scope as pictured.

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.

Bausch & Lomb Surveying TransitBausch & Lomb Surveying Transit  Bausch & Lomb is most famous for their line of binoculars and other optics but ventured in to the surveying instrument field after George N. Saegmuller, the inventor of the solar attachment that bears his name,  joined the company in 1905. They stopped making instruments for the general public during WWI so they were not in the surveying instrument business for long. There is a nice history on the company at the SurveyHistory.org site.

This transit has the logo the company adopted after 1907 and dates from right around that time period. The transit comes in the proper original box. It is a large, heavy, and overall nice condition piece. All motions are free, optics OK but not really crisp, good bubbles, crosshairs, etc. Box is nice.

G. W. Wilson Concord New Hampshire c. 1877 Transit TransitG. W. Wilson Concord New Hampshire c. 1877 Transit This unusual Engineer size Surveying transit is in very nice condition. Smarts book has a short Bio on G. W. Wilson, an early New England maker, but scant other info comes up with Google searches.  He is not in the Smithsonian 's list of makers, nor listed in the Compass Makers Directory.

Note the very unusual pillar style round standards. They have a great look and are a near unique feature for transits.   All the bubbles are good.  Compass points north and the compass face is nicely engraved.  Nice even patina. Also included is the correct and proper taper leg tripod (not pictured).  You must view the pics to see how nice and different this instrument is from the typical instruments from this era.  The compass is clearly marked with the maker name and location as well as the 1877 date.   A nice piece that will fi into many different collections.

Breithaupt / Kassel Mining Suspension Theodolite in BoxBreithaupt / Kassel Mining Suspension Theodolite in Box   This unusual instrument is NOS never been used.  It appears it was sold through K & E and dates from the 70's.  There is a translated set of instructions for use and a K & E bulletin announcing their carrying the product is included.  Basically it is a theodolite designed to be hung upside down from preset points installed in mines or tunnels. 

I found another in a collection with a good description http://www.sage.unsw.edu.au/currentstudents/ug/projects/f_pall/html/t11.html.   I did not do a good job of showing the knuckle joint like attachment on the bottom that one would use to mount it from the ceiling of the mine or tunnel.  Different, Unusual, and Very Nice!!

William Young ALUMINUM TransitWilliam Young ALUMINUM Transit  A unusual and nice example of William Young's work. Young is credited with producing the first surveying instruments known as transits in the 1830s.  The serial # of this transit is in the 8000s thus dating it from shortly after the turn of the century and before they sold out to K & E in 1918 or so.   The use of Aluminum in surveying instruments, because of the light weight, is quite unusual on instruments this early. Aluminum was still a relatively new material to work with and had drawbacks in use.  As can be seen some parts are in brass as well, and the contrasting materials, and finishes give it a very pleasing look.

The transit has been cleaned and adjusted. The motions are OK noting some stiffness in the main plate vernier.  Good optics w/ crosshairs.  It comes in the original box.  The fixed leg wooden tripod, with an Aluminum head is included as well.

Queen & Co. Aluminum Transit w/ Tripod This is an unusual light mountain size Aluminum transit by the well known PA maker Queen & Co. Aluminum transits by any maker from this period are pretty unusual. According to information provided by the well known surveying instrument collector Mike Beal, it is only the 2nd known Aluminum transit known by Queen. The serial # is 5505. It weighs a mere XXXX. Similar instruments in brass would weigh close to twice as much.

The scope is 8" long and the plate measures approx. 5 1/2. The needle is 4". The compass face has a great looking patterned finish that is very unusual. It also has an unusual 3/4 vertical arc as opposed to a full circle or 1/2 circle that one would normally see. Another unusual feature is the tripod mount.  It is a clamp on style as opposed to the typical threaded mount. The optics and crosshairs are good. All motions are free. Bubbles good.  It has a great look with its near all aluminum construction and just the screws and a few aux. pieces in brass.  An interesting and nice condition instrument for the collection that will make for a nice display piece.

Young & Sons Aluminum Transit w/ Smith Solar AttachmentYoung & Sons No. 10 Aluminum Transit w/ Smith Solar Attachment This is a rare Young solar transit with an unusual Smith Patent Telescopic Solar attachment. This transit is called off as No. 10 in an early Young catalogs. The patent for the solar attachment was first granted in 1880. This example is an improved model that was patented in 1902. The 8513 serial number on the compass face indicates it dates from shortly after the turn of the century.

It has a 4" horizontal circle, a 4" silvered vertical circle, a 3.3" needle, and a 10" main telescope. The brass telescope on the Smith solar unit is 7" long, and is inscribed "Pat Sep 16, 1902." There is a counterweight that mounts on the standard opposite the side with the solar unit. All motions are free and move smoothly. The compass works as it should. Note that there is a vernier scale on the outside plate, and another under the glass.

Young's use of Aluminum for many of the different parts of the transit is very unusual for an instrument from this time period.  Although quite a bit lighter than Brass it was also quite brittle and prone to crack.  Its formulation had not yet been perfected to alleviate that problem. There has been a repair done to an aluminum part of the leveling head that can be seen from the bottom.  A brass ring has been epoxied to the aluminum bell shaped housing part of the leveling head as it was cracked.  That seems to have fixed the problem and it mounts to a tripod with no issues.  The transit fits into the lift top box with the solar attachment in place. The box shows age but is OK.  The proper tripod is available for an additional $200.00.

Antique W. & L. E. Gurley Aluminum Solar CompassW. & L. E. Gurley Aluminum Solar Compass  Gurley Aluminum Solar Compasses are amongst the rarest of the rare in antique surveying instruments. Gurley made an aluminum version of their solar compass for just a few years in the 1890s and only a handful are known to exist or thought to have been produced. Gurleys' use of Aluminum during this time period was very unusual.  Aluminum was a relatively new material whose characteristics had not been fully developed, nor understood, or had been perfected. The finished compass, while much lighter than one made of brass, is also much more fragile. Aluminum from this period was very brittle and prone to crack.

One Aluminum Solar Compass came to market at Skinners Auction 15 or so years ago and brought over 17K. I was told it later sold for 60K. There is another example currently on eBay as of Sept 2020 priced at 24K. The author of that ad, a well known authority on antique surveying instruments states that his is one of only a few others known. That would make this the 3rd or fourth known example.  I had another collector tell me of a couple others he was aware of. 

I went inside this one looking for a date or maker info. I saw no date info. The number 14 was stamped under the plate.  The Burt Solar Attachment is also stamped # 14.  It could be a serial # or have another explanation. There were some other marks and scratches inside, but they appeared to be reference marks related to assembly.

Inside the original fitted box, in the top compartment, is a dead mint 1920 Gurley Catalog and some other Gurley marked material from the same era. The catalog is still in the original mailing envelope. There are also some newspaper scraps used for packing that are dated 1920. I believe the compass itself dates from the 1890s, some 20 - 30 years earlier, and that the instrument with the 1920 catalog went into storage around 1920.W. & L. E. Gurley Aluminum Solar Compass Rare Antique

The overall condition of this example is every nice.  Both level vials are good although one is blue and one a later clear replacement. All motions and adjustments turn freely. There are two bases. One is a brass leveling head, and one a more typical brass knuckle joint for mounting the compass to a tripod. The striding level is present as is the adjustment bar. The striding level is full, but appears to have a hairline crack in it.  There are also two small sight vane attachments with a fitted spot in the box. The tops of the sight vanes are different designs, one rounded and one w/ a peak.  The cutouts, patina, and finish match on both and I believe they are "right".  One thing to note is that the holes through the aluminum plate under both sight vanes have been slightly enlarged for some reason.  This Gurley Aluminum Solar Compass is an amazing instrument that will fit into many different collections. A rare opportunity.

The serial # begins with a 28 dating it from 1928. From the label in the lid of the box it appears this was used in South America. Levels with extra long scopes like this were used to layout long level lines in the field for railroad track, roads, and the like. The rear eyepiece has to be held and twist tension applied for the rear focus to work properly and not skip. The crosshairs are good, and the optics are OK as well. The scope has been polished.

World War II Era Mark V English HeliographsPair of World War II Era Mark V English Heliographs This pair of World War II Era Mark V English Heliographs are in nice condition and pretty complete.

Heliographs are basically signaling mirrors on stands that were used as a means of communicating over long distances by reflecting light back and forth between the mirrors. Morse code, or other codes were used. Early versions date from the mid 19th century. The English were still using them into the 1960s. Wikipedia has a long detailed write-up that fully explain their history and use.

The entire setup includes two tripods, 2 mounting brackets, 4 mirrors, 2 leather cases, 2 cans of replacement mirrors, and 3 articulated arms - w/ one being an extra.

The tripods are marked as shown in the last pics. Note how the legs are shaped in such a way that when folded up they form a circle. The original leather cases are also marked. One case has dividers inside, the other does not.

A very nice and interesting piece of surveying history that are becoming very hard to find.
