HENRY E. BOWEN, OF MILTON, OKLAHOMA.

WRENCH.

Application filed April 19, 1919.

To all whom it may concern:

Be it known that I, HENRY E. BOWEN, a citizen of the United States, residing at Milton, in the county of Le Flore and State of Oklahoma, have invented certain new and useful Improvements in \Vrenches, of which the following is a specification.

This invention relates to an improved wrench and the principal object of the invention is to provide a wrench of the combination type in which there has been provided a handle or body portion having an alligator Wrench structure at one end and a pivoted jaw structure and actuating means for the pivoted jaw structure at the opposite end of the handle, an auxiliary supporting hook or grapple being associated with the wrench and cooperating therewith for suspending the wrench from a. support or for holding a pipe or other article in engagement with the wrench.

Another object of the invention is to so construct the pivoted jaw structure of this wrench and actuating trigger for the same that the pivoted jaws may be easily held in an open position when the wrench is extended to engage a pipe or nut and the jaws then brought into tight engagement with the nut orpipe.

Another object of the invention is to soconstruct the auxiliary support or grapple that it may be connected with the wrench at various points for either suspending the wrench or for engaging an article to be turned.

Another object of the invention is to so construct this wrench that the strain will be removed from the pivot pins thus preventing danger of the pins breaking.

This invention is illustrated in the accompanying drawings wherein:

Figure 1 is a view showing the improved Wrench in side elevation,

Fig. 2 is a view similar to Fig. 1 with a portion of the handle or body portion broken away to show the mounting for the pivoted jaw and actuating trigger,

Fig. 3 is a view showing the improved wrench when looking at one edge face thereof, and

Fig. 4 is a perspective view of the grapple used in connection with this wrench.

This wrench is provided with a handle or body portion 10 which is provided intermediate its length with a cut-out forming a Specification of Letters Patent.

pocket 11 closed by a side plate 12 held in place by the screws or other removable fasteners 13, 14.- and 15. One end of this handle or body is extended to provide the rigid jaws l6 and 17 which have their inner edge faces cut to provide a nut receiving socket or opening 18 leading to a tapered recess where th inner faces of these jaws 15 and 17 are cut to provide alligator teeth 19. The opposite end portion of this handle is extended to provide a jaw 20, the inner edge portion of which is cut to provide teeth 21 for a pipe wrench jaw and inner teeth 22, the inner teeth being separated from the teeth 21 by a lug 28.

The movable jaw 24 and trigger 25 are pivotally mounted in the forward and rear end portions of the pocket 11 and have rounded inner end portions having close engagement with the walls of this pocket so that strain will be removed from the pivot pin 26 and 27 as will be hereinafter brought out. The movable jaw 2% is provided with ratchet teeth 28 for engagement by the bill 29 of the trigger 25 and it will thus be seen that when the trigger is moved forwardly as shown in Fig. 2 the bill thereof will engage the ratchet teeth of the movable jaw and thus swing the movable jaw into a clamping position and retain the jaw in this position. As the inner end of the trigger is in close engagement with the walls of the pocket pressure will come against the handle and not against the pivot pin and therefore there will be no danger of the pivot pin 26 or pivot pin 27 being bent or broken. The trigger is connected with'the movable jaw by the links 30 which have their ends bent to provide pins fitting into sockets formed in the trigger and jaw thus permitting free movement of the links. The adjoining ends of these links are formed into eyes so that these links will be loosely connected thus permitting proper movement without danger of the links becoming bent. The free end portion of this movable jaw has its ininner face portion cut to provide a jaw face 31 cooperating with the jaw face 21. To the rear of this jaw face 31 there is provided a lug 32 positioned in operative relation to the lug 23 and separating the jaw face 31 from the teeth 33 positioned opposite the teeth 22 and cooperating with the teeth to form a socket 34 in which a nut may be gripped, It should benoted that these teeth 22 and 33 permit nuts of different vided with a bridge 35 having arms 36 ex tending therefrom and terminating in hooks 37 provided upon their inner edge faces with teeth 38. This grapple when not in use will be put in place as shown in Fig. 1 with the bridge seated in the notch 39 and the arms extending longitudinally of the handle with their hooked ends fitting into the seat 40 formed in the sides of this handle. Notches 41 and 42 are formed in the trigger 25 and a notch 43 is formed in the handle where the edge face thereof is cut to pr vide teeth 44. The object of these notches will be brought out in the operation of the wrench which is as follows:

When this wrench is in use it may be grasped by the handle with the thumb engaging the trigger and the trigger moved to swing the movable jaw to an open position. The nuts or pipes to be turned can then be engaged between the stationary jaw 20 and the movable jaw and the trigger then moved to engage the ratchet teeth of the movable jaw and retain the movable jaw in tight en gagement with the article to be turned. A pipe will preferably be engaged between the faces 21 and 31 of these jaws but a nut will be engaged in the socket 34 and positioned therein according to the size and shape of the nut. This wrench may be rocked back and forth upon the nut or pipe, the trigger being moved to release the movable jaw from tight engagement when the wrench is being moved to obtain a new hold, the trigger being then moved to bring the movabl jaw into tight engagement when turning. If it is desired to suspend the wrench thus making the operation easier the grapple may beput in place with the bridge fitting into one of the notches 42 or in the socket 34 and the hooked ends of the grapple engaglng a suitable support. The end portions of the stationary jaw 20 will b provided with longitudinally extending teeth so that the wrench may be suspended through the medium of the grapple and the end of this jaw then brought into engagement with a bolt head thus holding the bolt against turning while the securing nut for v the bolt is being tightened. When found convenient the nut or pipe may be engaged with the opposite end portions of the wrench, a nut being preferably engaged in the socket 125. A. nuthaving a smooth face or a small pipe would be engaged inthe alligator wrench at the inner end of the socket 18 and a large pipe would be engaged by the teeth 44. When using the alligator wrench or engaging a pipe with the teeth 44 thegrapple will be put in place with its bridge fitting in on of the notches 41 and its hooked ends engaging the pipe. The movable jaw would then be grasped and pressed toward the stationary jaw 20 thus swinging the trigger to draw upon the grapple and hold the pipe in tight engagementwith the alligator wrench or teeth 44. Therefore the movable jaw and trigger 006perate with th grapple to hold the grapple in a positon to retain a pipe in operative engagement with the alligator wrench or teeth 44. The jaws 16 and 17 may also be pro vided with longitudinally extending teethv along their outer edge faces thus permitting them to be brought into engagement with a bolt head with the grapple in place and its bridg positioned either in the notch 39 or 43 and its hooked ends engaged with a suitable support or brace. It will thus be seen that there has been provided a wrench which can be conveniently used and in which. the movable jaw may be moved into and out of operative position through the medium of the trigger and further that the trigger can be moved through the medium of the movable jaw to impart movement to the grapple and hold a pipe engaged by the grapple in engagement with teeth of the wrench.-
