Description

WALTER P. WHITAKER, OF MISSOULA., MONTANA.
WRENCH.
Specification of Letters Patent.
Patented Nev. 9, 1915.
Application filed .Tune 21, 1915. Serial No.V 35,385.
To all whom t may concern.'
Be it known that I, VALTER P. WHITAKER, a citizen of the United States, residing at Missoula. in the county of Hissoula, State of Montana. have invented certain new and uset'ul Improvements in lVrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
rlhis invention relates to improvements in wrenches.
One object of the invention is to provide a sliding jaw wrench which is automatic in its nature.
Another object is to provide a sliding jawV wrench which is positive in its gripping action on a piece of work and which will return to normal position whenreleased from the work.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawingzvFigure 1 is an elevation of a wrench made in accordance with my invention. Fig. 2 is an edge view, Fig. 3 is a longitudinal sectional view on the line 3 3 oi" Fig. 2. Fig. 4t is a section on the line or' Fig. l, Fig. 5 is a longitudinal section on the same line as Fig. 3, but showing the movable jaw and extension in elevation, and 6 is a perspective view of the removable jaw, removed. f
.Referring particularly to the accompanying drawing, 10 represents the shank of the wrench which has formed on one end a head 11 provided with a stationary jaw member l2 and having formed transversely the/reet a slot 13 which widens toward an edge ot the wrench inwardly ot the outer tace of the stationary jaw. Within this slot is a .substantially triangular plate 14e on the smaller end ot which is formed a jaw 15 which slides toward and away from the stationary jaw 12 as will be understood. Likewise within Vthe slot 13 and connected at one end to the plate 14 and at its other end to the head is a coil spring 16, this spring normally drawing the jaw l5, to the outermost limit ot' its movement. away from the jaw 1Q. Formed longitudinally through the shank `is a channel 17 in which is disposed a rod 1S, one end being beveled and bearing against the adjacent inclined edge of the ceives the rib 23 carried by the section 20 of the handle. 0n the inner end of the rib is a. projection 24 which engages with the kadjacent end of the rod 18.
In normal position, the arm 15 is in position away from the arm 12 and the member 2() extending outwardly at an angle from the shank. The jaws are thus in position to straddle a piece of work which is of a size equal to the distance between the jaws. By swinging the member inwardly toward the member 19 the projection 2e will engage with the end of the rod 1 8 and force the same outwardly so that its beveled end will engage the inclined edge ot the plate 14 and force the jaw 15 against the arm 12 and iirmly clamp the work between the jaws. The mutually adjacent faces ot the jaws are ribbed, as shown at 25, j to be received in the grooves of the toothed plates 2G Jfor engagement with round work such as pipes, said toothed plates being secured in place by the set screws Q7.
That is claimed is:
1. A wrench comprising a shank having a longitudinal bore formed therethrough, a stationary aw member formed on one end oi the shank and having an outwardly widening channel formed therethrough, a movable jaw carrying an extension of the same size and shape as the said opening and disposed therein, a rod slidable through the here of the shank and having a beveled end engaging with the adjacent inclined edge tace of the said extension, means for holding the movable jaw remote from the stationary jaw, and means carried by the other end ot' the shank for sliding the rod in the bore to move theV movable jaw toward the stationaryjaw.
2; A. wrench including a shank having a longitudinal bore and a rod slidable therethrough and provided with a beveled end, a stationary jaw and a movable jaw carried by one end of the shank, an approximately triangular member carried by the movable jaw and slidable under the stationary jaw, the beveled end of the rod engaging with one ot the inclined edge faces oi' the triangular member, a spring connected to the shank und to the movable 'aw YF01' holdin@ lzmfrular membl and move the movable the movable im' away from the Stationary j 11W toward the statnnmy jaw. 1C jaw und a pvoted hand grip carried by the In testimony whereof, my signa- Otber end of the. shank and provided with ture, in the presence of two Wtnasses.
