Manufactured by Owsley Brothers & Marble - Chicago IL

Handle comprised of a wire or rod bent to form two parallel rods. The adjustable jaw slides on the rods, one of which is threaded to engage an adjusting nut. At various points these were manufactured in sizes 4" through 21," with several finishes, and with and without the twist handle. Whitman & Barnes took over the ACME wrench line from Capitol Mfg. in 1893. There were multiple models, including "Agricultural" and "RAILROAD," and a modification which moved the adjusting nut from the "front" to the "back" rod. By 1915, Whitman & Barnes had apparently ceased production of the ACME wrench. The patent was also used as the basis for subsequent pipe and nut combination wrench patents -- e.g. no. 447,665, and was "improved on" by patent no. 460,539. The design also had "imitators" - notably from 1920s German makers. An early iteration of the combination wrench was called HOLLAND'S ACME, but the "Holland" has not been identified.

Manufactured by Allen Manufacturing Co. - Hartford CT
Assigned to Ira Dimock - West Hartford CT

The patent describes a process to form sockets in the heads of screws, using an angular punch and round die. Allen Safety Set Screws which had no protruding heads were a primary application for the process; the process was also used to form socket headed screws of various types, pipe plugs, and detachable sockets for a variety of socket wrench sets. All these were produced and sold by the Allen Mfg. Co. of Hartford, CT. The hexagon wrenches for the socket headed screws gave us the generic "Allen wrench."

Assigned to Moore Drop Forging Company - Springfield MA

A spring-loaded central shaft has a tapered recess which allows the socket-retaining ball to retract. The specifications note this feature applies to ratchet wrenches of the type described in patent no. 2,772,763. They also note a release plunger described in patent no. 3,208,318. The patent appears along with 3,172,675, 3,208,318 and 3,467,231 on a CRAFTSMAN 43178 1/4" drive ratchet.

Assigned to Williams, White & Co. - Moline, Rock Island County IL

Patented in Canada, #CA-152152. Abstract: My invention relates to apparatus for forging crank shafts, and more particularly to a set of dies and their fittings and supports adapted to be operated by power for the bending and forging of crank shafts. The apparatus herein to be disclosed is shown of a nature permitting it to be employed on various power operated machines or presses whether horizontal or vertical, such for example as the ordinary punching press or a hydraulic press or the machine know n as a bulldozer; there being in each instance a reciprocating part such as the crosshead of the bulldozer, with which certain of the die mechanism cooperates, and a stationary member to which other parts of the die mechanism are secured. The present improvements are particularly intended to be operated by power in one way or another. An object of the present invention is to enable the production of crank shafts with full stock at the corner of the bends and in an efficient and satisfactory way, this being one of the problems with which forge shops have always contended. Another object is to permit the bending of the shaft and the upsetting or the formation of full stock at the corners in a single operation and by the single apparatus hereof. Crank shafts made in a drop forge have required a tedious and expensive operation and machinery. the finished shaft being forged down out of large sized material and the material thereby considerably distorted. Claim: In a crank shaft forging apparatus, the combination of an actuator adapted to make a forward stroke, mechanism actuated by said actuator operative in the first part of each forward stroke for producing all the bends of the crank, and mechanism actuated by said actuator operative in the last part of each forward stroke thereof for upsetting the corners by displacing the crank wrist relatively toward the shaft line. 2In a crank shaft forging apparatus the combination of a movable actuator or head, a shaft bending means for making all the bends of the crank, connections whereby the actuator actuates said bending means, and an upsetting die for displacing the crank wrist toward the shaft line after said bending means has bent the shaft, and connections whereby the actuator actuates said die, said respective connections being such that a single operation of the actuator causes the operations in the order named.

Munn & Co.- patent attorneys Abstract: In building piers of masonry for bridges and other structures over water the piers are in many cases built on platforms which are powered into the water from time to time as the work progresses until the platforms rest on the bottom. The platforms now used for such purpose are supported by screw-rods from a suitable framing and the nuts of the rods turned independently and separately by operatives when the platforms are to be lowered, The difficulty attending this arrangement is the expense and tediousness of the operation of lowering, and also the care required in keeping the platforms level or horizontal, as the rods require to be lowered precisely alike. The object of the within described invention is to overcome these difficulties; and to this end I connect the nuts of the several screw-rods by mechanism so arranged that all the nuts will be operated simultaneously from one and the same driving-shaft, and consequently not only much labor saved in lowering the platforms but the horizontality of the same always preserved. Claim: The connecting of the several nuts D of the screw-rods B to a common driving-shaft J, substantially as shown or in an equivalent way, when said screw-rods and nuts are employed to sustain a platform C for the purpose of lowering piers into the water during the course of construction.
