Application mea March io, 1 919. serial No. 281,731.
To all whom t may concern:
Be it lniown that I, HOWARD Gnirrz- BRownR, citizen of the United States of America, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful linprovements in Wrenches, of which the following is a specication.
This invention relates to certain new and useful improvements in wrenches of the sliding adjustment type, and has for its primary object, the production of a wrench of most simple construction and comprising but few parts, each of which will bestrong and durable and the entire wrench will be. economic as well as simple.
lA Vfurther object of the invention yis to construct the wrench in such a manner that it may be used as conveniently as and in all places where the ordinary pipe and nut wrenches are capable of being applied.
Other objects will become apparent as the nature of the invention is better understood and the same consists in the novel construction and combination of the several parts as will be hereinafter fully described, shown in the accompanying drawing and embodied in the appended claims.
In the drawing, in which like. reference characters indicate similar parts throughout the several views, Y
Figurel is a side elevation of aV wrench constructed in accordance with the present invention with the bolt of the fastening device in section,
Fig.k 2 is a sectional view'of the device taken substantially upon line II-II of Fi l,l Y
Fig. 3 is a view similar to Fig. 2 with the fastening device in a diiferent position and the nut thereof in elevation, v
Fig; 4 is a view similar to Fig. 2 with the fastening device in a still further position and the nut partially unscrewed from the bolt of the fastening device,
Fig. 5 is a side elevational view vof one of the sections of the wrench,
Fig. 6 is an edge elevation of the device shown in Fig. 5 looking toward the left of said gure, and A Fig. 7 is a sectional view taken substan-` tially upon line VII-VH of Fig. 5.
The-present wrench comprises virtually three parts only, "namely, a body portion constructed in two sections A and B anda fasteningdevice C. The section A of the body comprises a shank 5 having an inner smooth-faced ljaw rigid on one end thereof and a similar outer oppositely directed jaw 7 upon the other end thereof. Itis noted that the engaging faces of jaws 6 and 7 are directed at an inclination relative to the longitudinal axis of shank 5.1 The section A is preferably stamped from sheet metal with a laterally extending plate .8 integral with ,the side thereof opposite the jaw 6, said plate 8 being depressed'out of butparallel with the plane of the shank 5. The plate 8 has a flange 9 along the free longitudinal edge thereof which together with the adjacent portion of the opposing longitudinal edge of shank 5 provides a suitable` guide-way for snug sliding reception of the shank 10 of the body section B.
The section B has an outer rigid toothed jaw l1 on one endthereof cooperating with the jaw 6 of shank 5, and said shank 10 is operatively disposed', are arranged with adl jacent longitudinal edges in contact so that said Shanks are within the saine plane instead cf being superimposed withvfla't sides contacting as is the case with the wrench in United States Patent 482,198 to John' Ryan, dated September 6, 1892 and over which this inventionV constitutes an improvement. rIhis difference of construction naturally pla-ces the jaws 6 andV l1, and 7 andl2 in opposing relation without'. laterally directing any of the same and enablesthe wrench to fbe readily stamped from sheet material with as little shaping as possible. The working face of jaw 12V is inclined in a direction parallel with the working face of jaw so as to cooperate with the latter `in turning nuts or the like. On the other hand, the toothed jaw V1l has the working face thereof inclined in a ldirection oppositev to the inclination of the working face of the coperatingjaw so as to provide, vin effec@ an alligator wrenchv serviceable in v turning pipes or other round work.-
As the flat inner face of flange 9 is paraltive to shank 5 which might cause Shea-ring action of the bolt 13 forming part of the locking device C as will later become apparent.
The plate 8 is constructed with a longitudinal slot 1/-1- having opposite lateral notches 15 extending therefrom at intervals and of angular formation as clearly shown in Fig. 5. rilhe intermediate portion of shank 10 is also provided with a longitudinal slot 16 having a number of staggered lateral notches 17 extending into opposite edges thereof, said notches 1'? being` also of angular form and preferably being greater in number than those of the plate 8.
The fastening' device C comprises in addition to the bolt 13, a suitable nut 18 threaded upon one end of said bolt so as to clamp the shank 10 firmly against the plate S and thereby prevent relative movement of shanks 5 and 10. lV ith the locking devices disposed as in TEig. 3, the shank of .bolt 13 is situated within the slots 1-1- and 16 so that the fastening e'd'ect is merely of a frictional or clampingnature and, as inv some instances, the fastening' effect should be of a positive nature, the notches 15 and 1T are provided so that when the proper adjustment has been had between shanks 5 and 10 to enablejawg G and 11 or 7 and 12 to properly engage the work,'certain ones of the notches 15 of the plate 8 and notches 17 of the shank 10 will be coincident so that the shank of bolt 13 may be situated or positioned therein and thus positively prevent relative longitudinal displacement of shanks 5 and 10. rIhis positive locking position of the bolt 13 is clearly illustrated in Figs. 1, 2, and et and it is obvious, that if shank 10 were allowed to swing relative to shank 5, a shearing action would be had upon the shank of bolt 13. However, as above pointed out, the manner in which shank 10 is guided by shank 5 and the flange 9, effectively prevents this shearing action by rendering impossible any lateral movement of the shank 10 relative to shank 5.
The wrench is used in the following manner:
By turning the nut 18 partially off of the shank of bolt 13 as shown in Fig. l, the locking device may be nioved laterally into the coincident slots 14 and 16 and the sections A and B may be'longitudinally moved relative to each other in the desired direction so as to obtain the proper adjustment between the jaws being used. lVhen the jaws have grasped the work, the nut 1S is turned upon the bolt 13 so as t0 frictionally and firmly hold the body sections together' as shown in Fig. 3. However, if the positive fastening arrangement is desired, the bolt 13 is positioned within coincident notches as shown in F 2 before the nut 18 is tightened. By arranging the notches 17 in staggered relation and the notches 15 in opposing relation, it will be apparent that a maximum number of minute adjustments may be obtained.
lt will be observed that this wrench comprises but very few parts, that each part may be economically and durably made, and that when all of the parts are assen'ibled the wrench is capable of being` expeditiously, effectively and conveniently manipulated and may be used wherever a pipe or nut wrench is to be employed.
While the form of the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, combination and arrangement of parts without departing from the spirit and scope of the invention as claimed.
Vhat l claim as new is:
