WAGON-WRENCH.
SPECIFICATION forming part of Letters Patent No. 533,844, dated February. 5, 1895. A Application filed September 29,1893. Renewed January 11, 1895. Serial No. 534,592. (No model.)
To all whom it may concern..-
Be it known that I, GEORGE E. DUNHAM, of Hebron, in the county of Oxford, State of Maine, have invented certain Improvements in Wagon-Wrenches, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to wagon wrenches designed specifically for use in connection with the nuts commonly employed oncarriage axles for retaining the wheels in place on the axle but the invention is possessed of more or less general utility in other matters.
The nature of the invention is fully described hereinafter and specifically pointed out in the claims.
Referring to the drawings Figure l is a side elevation of my wagon wrench complete. Fig. 2 is a perspective view of the two clamping jaws detached. Fig. 3 is a similar view of an accessory block to be used in the clamping jaws, and Fig. 4 is a sectional view of the complete wrench with the accessory blocks in position for use.
'The frame A, is provided with a tang on which is arranged the handle B. The tangis located at the center of the frame and is arranged to turn freely in the handle B. Said frame A is further provided with upwardly extended arms a, a, in'which is arranged the rod 0, the rod being arranged to permit of being revolved in its bearings and on the ends of the rod are knobs b, that serve as handles whereby to manipulate the rod. On the rod 0 are arranged the clamp-jaws e c with their bottom ends engaging the edge of the frame A, the-ends of the'clamps being grooved to receive the edge of the frame and thereby get a suitable bearing or grip thereon. The jaws are arranged to permit endwise movement along the rod 0 and on the rod 0 are fixed the cams f, f, each provided with a cam leaf tively to the point where the tang on the frame A, if extended forwardwould cut the rod, that is, the clamps are arranged equidistant from this point.
In operation the workman places one hand upon the handle and the other upon the knob b and having placed the wrench over the nut he turns the rod 0 thereby causing the clamps to close up and take hold of the nut. The wrench is then turned sufficientlyto start and loosen the nut. Thereupon the wrench is rapidly revolved by momentum imparted from the hand of the workman and the nut is quickly removed.
' The knobs b are made of metal so as to weight the ends of the rod 0 and thereby adapt it to revolve with greater force and momentum.
, Theclamp jaws are formed with an angle corresponding to the angle or shape of the corner on the nut where the jaw is to be applied. The n of commonly employed on carriage axles being a square nut I prefer to make the angle in, the main clamp-jaws aright angle but in many cases it is desirable to use the wrench on a nut having more or less than four sides. To this end I provide the accessoryjaws represented fully in Fig. 3 of the drawings. These accessory jaws may be combined with the main clamp-jaws as fully represented in Fig. 4, the tang 4 on the accessory jaw being set into a suitable hole or socket formed in the bottom of the main jaw while the spring 5 operates to keep the top of the jaw close into the angle of the main jaw. This accessory jaw is provided with an angle to conform 'to the peculiar shape of the nut on which it is .to be used and in this way the wrench may be prepared for use on any style of nut.
Having thus described my invention and the manner of using the same, what I claim as of my invention, and desire to secure by Letters Patent, is-
1. The combination in a wrench, of the frame supported upon a swiveled base, a pair of clamping jaws sliding horizontally on said frame, a rod supported in said frame and extending through said clamps and terminating in a handle, and intermediate connections between saidrod and clamps; whereby they may be opened and closed; substantially as described.
2. In a wrench the combination of a frame, a swiveled supporting base, clamping jaws sliding horizontallyin said frame, a rod passing through said jaws, having its hearings in said frame, and terminating in a handle, and cams secured to said rod in rear of each jaw adapted to operate simultaneously, to open 'and close the jaws as the rod is moved in one direction or the other; substantially as described.
3. In a wrench, the combination of a frame, a swiveled supporting base, jaws sliding in said frame, a rod passing through said jaws, and having its bearings in said frame, cams f, having flanges 7i, and grooves 72, in the rear ends of the clamping jaws adapted to receive the flanges of the cams, whereby, in the operation of the red, the jaws are opened or closed; substantially as described.
4. In a wrench havinga suitable supporting main jaws, and springs 5, in rear thereof; all
substantially as described.
