1964. Approximately 24" tall:

1965. Sent in by a visitor who is looking to find the purpose of this tool:

1966. Another unidentified item that was sent in by a visitor, the 18" rods are made of solid stainless steel except for the red one which is plastic:

1967. About 3" diameter, take a look at Neatorama for more guesses on this one and a chance to win a prize:

1968. Around 17" tall, this is step one in the making of a particular product:


1963. A "Screw Thread Gaging Device", patent number 1,223,012:
...for gaging and testing the pitch or "lead" of screw threaded parts...for determining whether the threads on an article, as for instance a tap, die or other threaded piece, and designed to be of a certain number to an inch are truly formed as per the requirement, or at variance therefrom to an appreciable extent.

Text on it reads:
Bicknell-Thomas Co.
Greenfield, Mass. U.S.A.
Pat. Apr. 17, 1917

1964. A protective cover for a fire hydrant, it's marked:
Aug. 8, 1876

Patent number 180,830 was issued to Birkinbine on that date but it's for a fire hydrant, not for a protective cover.

The top of it states:
10 dollar fine for interfering with this plug
Manufactured by Variety Iron Works, York, Penn

1965. Probably a woodworker's router or scraper for use by a coachmaker:

1966. A listening device for finding defects in machines, motors, dynamos, or turbines, the instructions state:
...fix the end of the device (when needed mount the extension pieces together) on the external part of the examined surface such as a cylinder, gearbox, carb, differential, mechanical parts, pipes and so on. Put the membrane to your ear and diagnose by simply listening; defects such as oil deficiency, loose bolts, screws and so on with certainty. In danger of electrocution use the red insulated sound finder that neutralizes electricity. When checking for pipe defects hold the device to the raised examinated part such as hydrants and so on. It will work even through brick walls, bitumen and soil to diagnose the defect.

1967. An ice cube crusher, the patent states: is proposed to arrange the containers telescopically relative to each other and to provide a plurality of pointed elements mounted on the top and base wall of the containers and directed towards each other for cracking a piece of ice placed within the containers when they are forced together.

Patent number 2,147,394

From Bob Roger's collection

1968. A billet, an early stage of a bowling pin, it is "inserted into a lathe with a large blade in the shape of the bowling pin. The knife blade is pressed into the rotating piece of wood stock and the entire bowling pin is cut in one pass by the shaping knife blade."

  1. 1965 Clearly a router--similar to what is traditionally called an old woman's tooth. The spokeshave-like shape suggests that it was intended for scraping grooves on curved members. Perhaps a coach maker's tool.

  2. I agree with ghgoebel re: 1965. It looks like a homemade version of the old Stanley router plane #71

    My guess for 1968 is that it is the first step in making a bowling pin?

  3. 1967 - A biscut cutter - the nails are to put holes in the biscut for even cooking.

    1968 - One of the timbers for a mine shaft

  4. 1964 I'm thinking that this is one of those enclosed capstans for drawing ferryboat decks fast to docks.

  5. 1964. Is it a cover to put over fire hydrants that are out of service?

  6. Y'know, I was going to say that 1967 looked a bit like a bud-grinder. That would have been close (right application, wrong material).

  7. 1966 might be part of an annealing torch for metalworking or glassblowing of large pieces, but the picture does not show enough for a good guess.

  8. The 1996 looks like a portable candle snuffer (

  9. AWESOME work. And amazing assortment of tools to work... Really great!!
