Specification of Letters Patent.

Patented Aug. 4:, 1914..

Application filed August 8, 1913. Serial No. 783,730.

To all whom it may concern Be it known that I, EDWARD B. l/VADDELL, J12, a citizen of the United States, residing at Williamson, in the county of Mingo, State of WVest Virginia, have invented certain new and useful Improvements in -Wrenches; 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 th art to which it appertains to make and use the same.

This invention relates to wrenches, and has particular application to certain novel and useful improvements in a tool of this class which is capable of employment as either an ordinary nut or monkey wrench or as a pipe wrench.

In the present instance I propose to provide a wrench having a movable jaw, which under certain conditions, is designed to cooperate with a stationary jaw to grip nuts or other angular articles, and under certain other conditions this movable jaw is designed to cooperate with a swinging jaw for the purpose of gripping pipes or other cylindrical objects.

I further propose to so construct and corelate the various operating parts of my improved wrench that it may be quickly and readily adjusted to grip either an angular object or a cylindrical article.

It is also my purpose to provide a wrench capable of performing the two-fold function, above recited, and which embodies the desired features of simplicity, etlicicncy, reliability and strength, and furthermore, my improved tool may be manufactured and marketed at a relatively low cost.

WVith the above recited objects and others of a similar nature in view, my invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings: Figure 1 is a view in side elevation of the preferred form of my improved wrench, in this case the parts being shown in position gripping a nut. Fig. 2 is a similar view showing the wrench in position grasping a pipe. Fig.

is a view of the wrench with one of the sides thereof removed to show the interior construction and arrangement, the aws being shown as closed, certain operating parts of the wrench being shown in elevation. Fig. 4 is a back view of the wrench. Fig. 5 is a cross sectional view taken on the line 55 of Fig. 4. Fig. 6 is a view in elevation of a modified form of wrench.

Referring now to the accompanying drawings in detail, the letter A designates the handle of the wrench, which is preferably formed of two halves or sections in the well-known manner, these sections being connected by rivets or screws 1. Vithin the assembled tubular handle slides the shank bar 2, which is guided in its longitudinal movement in the handle by the guide plates 3 and 4. This shank is shouldered as at 5, which shoulder is designed to strike against the cross guide plate 4; when the shank is moved inward, so that the travel of the shank inward is limited by the plate l. The reduced portion 6 of the shank bar 2 is provided on one edge with a series of serrations or teeth 7 which are adapted to be engaged by the teeth 8 formed on the head 9 of the dog 10, which is pivoted at 11 to the lug 12 formed on the handle. This dog is provided at its and opposite the toothed head thereof with a lateral stud 13 which projects through the opening 14 formed in the adjacent wall of the assembled handle, this stud being pressed inward when it is desired to rock the dog upon its pivot to release the toothed head of the dog from engagement with the teeth or rack of the shank. The toothed head of the dog is normally pressed into locking engagement with the teeth of the shank by means of the spring 15 secured within the handle by means of the pin 16.

From the description thus far given, it will be seen that the shank bar 2 slides in the handle in the well known manner, and is locked in it predetermined position by means of the toothed head of the dog engaging with the teeth or rack of the shank, and that when it is desired to release the dog to permit the shank to be moved to a predetermined position, it is only necessary to depress thestud 13. The outer end of the shank 2 has a stationary jaw 17 of the form usually provided for monkey wrenches, the operating part of this jaw being shown at 18:

Sliding 0n the shank is a jaw 19 having a gripping portion 20, which is designed to cooperate with the portion 18 of the stationary jaw 17 when the wrench is used as a nut wrench, or for gripping angular articles, and this jaw 19 is also provided with an inclined serrated face 21 which is on the opposite side of the jaw from the portion 20, and this face 21 is designed to coiiperate with the swinging jaw 22 when the wrench is to be used for gripping cylindrical articles such as pipes or the like. It will thus be seen that the jaw19 is common to or cooperates with both thestationary jaw 17 and the swinging jaw 22. This jaw 22 is provided with a serrated gripping portion 23 which is disposed oppositely to the face 21 of the jaw 19. The jaw 22 is further provided with a relatively large bore so that it may slide or move loosely upon the shank 2. The back wall of the jaw 22 or that portion which bears against the back of the shank 2 is preferably provided with a small bearing roller 25. The lower portion of the swinging jaw 22 is formed with a rounded lug 26 which is designed to seat in a correspondingly shaped depression or socket 27, formed in the adjacent wall of the handle. This socket or depression 27 is made sufliciently larger than the lug 26, so that when the swinging pipe gripping jaw 22 is dropped into position to grip the pipe, the lug will bear against the inside wall 28 of the recess, while when the swinging jaw 22 is swung upward into engagement with the serrated face 21 of the aw 19, and when the wrench is being used as a nut wrench, the lug 26 will bear against the outer wall 29 of the depression or socket.

From the above description, taken in connection with the accompanying drawings, the construction of my invention will be readily apparent. If it is desired to use the device as a nut wrench, or ordinary monkey wrench, then the parts are adjusted to the position shown in Fig. 1. This is accomplished by depressing the thumb stud 13 so as to release the toothed dog from the rack portion of the shank, and the handle is moved relative to the shank until the inclined serrated face of the jaw 22 interlocks with the serrated face 21, practically forming a single jaw with the jaw 19. The jaws 19 and 22 are then adjusted or moved to gether so that the nut may be received between the gripping face of the jaw 19 and the gripping face 1.8 of the stationary jaw 17 The locking dog is then permitted to engage with the rack of the shank and the wrench is operated in the ususal manner. hen it is desired to employ the tool as a pipe wrench, the jaw 19 is shifted along the shank until it contacts or abuts against the stationary jaw 17. The dog is then released by pressing the thumb stud and the handle is moved relative to the shank so that the jaw 22 cooperates with the jaw 19 to grip the pipe. It will be noted, of course, that when the pipe is gripped between the faces 23 and 21 of the jaws 22 and 19 respectively, the jaw 22 will be tilted at an angle and will bind upon the shank, while the lug-28 of the jaw 22 bears against the inner wall 28 of the depression 27 In Fig. 6 T have shown a slightly modified form. of the invention, and in this instance I employ a sliding block 30 whichslides upon the shank 2, said block being shifted back and forth by means of the screw 31, which is in threaded engagement with the sliding block 30, this screw being operated by the thumb nut 32 in the well known manner, otherwise the operation of the wrench is substantially the same as that described for my preferred form.

Vi hile I have herein shown and described one particular embodiment of my invention, I wish it to be understood that I do not confine myself to all the precise details of construction herein setforth by way of illustration, as modification and variation may be made without departing from the spirit of the invention orexceeding the scope of the appended claims.

What I claim is 1. The combination with a body portion having a recess in one end thereof, of a shank slidable in the body portion, a stationary at one end of the shank, a swing-- ing jaw slidable on the shank and having a projection adapted to seat within the recess in the end of the body portion, said projection being substantially smaller than the recess whereby when the swinging jaw is swung downward the projection will bind against one wall of the recess, and when the jaw isswung upward said projection will bind against the opposite wall of the recess, a sliding aw mounted on the shank intermediate the stationary jaw and the'swinging jaw and having one gripping face adapted to cooperate with the gripping face of the stationary jaw and another gripping face adapted to cooperate with the gripping face of the swinging jaw.
