UNITED STATES PATENT OFFICE,
GEORGE P. GANSTER, OF NEW YORK, N. Y.
IMPROVEMENT IN wRENoI-IES.
Specication forming part of Letters Patent No. 54,888, dated May 22,1866.
`To all whom it may concern Figure 1 represents a side view of Iny wrench; Fig. 2, a similar one of the reverse side; Figs. 3 and 4, sides ot1 slidingbar; Fig. 5, a top view of the volute cam or wheel; Fig. 6, a section on line a b, Figs. 1 and 2.
A represents the main frame or handle; a', its jaw n'xed. B is the rack-bar of sliding jaw b. B works inside of or through A.
On one side of B there are a number of curved teeth, c, which engage with the tooth d of wheel O, and a revolution of this latter raises or lowers the rack-bar B one tooth or interval.
dinary pinion-wheel, has an axis, e, passing This Wheel corresponds to an or- I through one side of A, and to which is secured a thumb-wheel, f, a nut, g, serving to hold the parts together.
On the reverse side of A there is a circular screw-piece, h, and a small projection, t', upon it enters a slot in B, acting as a kindof guide to it and limitingits movement. Thecircnlar hole in A, which h ills, permits the volute cam or wheel to be introduced from that side.
rlhe operation of my wrench simply consists in turning the thumb-wheelf, which can easily be done while holding the handle of the wrench, using for that purpose the thumb ot that hand.
My wrench is not only simple in construction, but the works 4are concealed, well protected from injury and dirt.
Having thus described my invent-ion, what I claim as new, and desire to secure by LettersPatent of the United States, is
A wrench constructed of the hollow frame or handle, A, the movable rack or hammenbar B, and the volute toothed wheel O, these several parts being combined and arramtedw in the manner substantially as set forth, and operating as described.
GEORGE P. GANSTER.
