Specification of Letters Patent.
Patented Nov. 6, 191 '7.
Application filed April 26, 1917. Serial No. 164,669.
7'0 all whom it may concern: I
Be it known that I, LEON GNrEwcRYfIsKI, a subject of the Emperor of Austria, resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates to improvements the'fixed aw 22 by means of the fiat spring in wrenches, and has as its specialobject the provision of a wrench in which the movable jaw is rapidly movable with relation to the fixed jaw and which is readily relieved from its control means.
A further object is to provide means of relatively thin construction, without having parts projecting from the side which might interfere with its usual operation, the wrench being essentially heavy and strong.
These and other like objects are attained by the novel. design, construction and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a side elevational view of a wrench made in accordance with the invention.
Fig. 2 is a similar view of the same, one ofthe cover blades being removed.
Fig. 3 is a view similar to Fig. 2 showing the parts in a released position.
Fig. 4 is an edge view of the wrench as shown in Fig. 1.
Fig. 5 is atransverse sectional view taken on line 55 of Fig. 3.
Fig. 6 is a fragmental view of the wrench looking from line 66 of Fig. 3.
Fig. 7 is a sectional view taken on line 77 of Fig. 6, and
Fig. 8 is a perspective view showing a screw-driver as attached at the opposite end of the wrench.
Formed with the body handle 10 are raised edges 11 and 12, respectively on the front and back of the implement, the same having recesses 13 and 14 suited to receive corresponding projections 15 and 16 formed 7 with the cover plate 17, which is held to the body handle by means of screws 18.
The head end of the wrench is materially thickened along both edges terminating in a fixed jaw 22 from which extends a diagonal bar 23, through which is formed a longitudinal slot 24, in which is slidably engaged the reduced shank 25 of the movable jaw 26, the shank 25 having inserted in it a rigid able against the lower or inner side of the bar 23, thereby holding thejaw in permanent engagement .but'permitting the same to slide freely along the bar, a recess 28 being provided in the bodyportion of the wrench in which the pin may operate.
The movable jaw 26 is pressed away from 32 held in the interior of the wrench handle by the screw 33 so .aswto normally present an opening between the jaws. v A sliding bar 38 is provided with an operating projection 39 andhas an angular head 40 adapted to engage, against the outer side :of the shank 25 f which obviously is caused totraverse the bar 23 within the slot 24 whenthe bar 38 is advanced toward the operative end of theimplement. This bar is normally held in position by means of the hollow handlelO by fixed pins 42 and 43 on one side and. the raised edges 12 upon the other. I I
Formed within theinner edges of-the bar 38 are a plurality of ratchetteeth 44, similar teeth being formedupon a lever 45 pivoted upon theshank of the screw 18 within the hollow body of the implement, and having a reduced extension 46 formed in the opposite'end, the outer-end of which rests against the outermost pin 43, the lever being normally pressed forward so as to cause engagement of the teeth by means of the fiat .spring 47 secured by thescrew 33.
In order to release the bar 38 so tha-t it may be moved rearwardly, thereby permit- -tingthe jaw 26 to be retracted, a knob 48 having a stem 49 passes transversely through the bar 38 and is provided with a fixed collar whereby it is prevented from pass ing outward and hence from loss, the point of the rod 49 being adapted to engage against the inner side ofthe extension 46 of the lever 45 by means of which it can be pressed back, overcoming the tension of the spring 47 and releasing the rod 38 which is moved back imder pressure of the spring 32 when the jaws are opened.
In operation, when it is desired to close the jaws, as upon an object to be turned, pressure is merely applied to the projection or plate 39, advancing the bar 38 toward the head of the implement and causing the jaw 26 to move in the direction of the fixed jaw 22.
When a su'flicient movement has been pin 27 having a flattened portion engagetransmitted, the teeth 14 on the element engage with the teeth on the lever l5, holding the bar 38 rigidly outward, and by means of the angular spear-shaped head i0, 7 holding the j aw 26 in its adjusted positlon.
YVhen it is desired to release the jaw, pressure is applied upon the knob d8, which moves away the lever 45, overcoming the tension of the spring 47 and releasing the engagement of the ratchet teeth, permitting the bar 38 to be moved toward the rear or lower end ot' the handle, the jaw 26 being caused to follow the'bar under action of the spring 32.
The opposite end or the implement may be used as a screw-driver, inserted nibs 50 being receivable between fiXed lugs 5'2 formed with the lower side 10 of the handle, the same having ends of varioussizes, as 53 and 5%, either of which may be held in an operative position through the slot 55, with which is engaged a dog 56 held normally within the slot by the spring 57 and operableby the extending lever 58.
From-the foregoing, it will be seen that a neat and-serviceable implement of pleasing appearance has been described and which can be operated as an angle wrench from either side in an obvious manner.
Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is 1- 1. In a wrench of the class described, the combination with a hollow body, a handle afiixed thereto, an integrally formed head, and a fixed jaw formed in said head, of a jaw slidable within said head, means for normally keeping said jaw in an open position, a bar 'slidably' engaged within said handle, sai'd' bar having an angular head engageable with said movable jaw, a plur'ality of ratchet teeth formed on one side 01": said bar, a lever fulcrumed in said casing having teeth normally engaged with said ratchet teeth, means for advancing said bar toward sa-id'head, and means for depressing said lever whereby said teeth may be dlsengaged.
2. In a wrench the combination with a hollow handle and a body, of a slotted head integrally formed therewith, a aw formed with said slotted head, a spring adapted to press said movable jaw away from said head, a bar slidablycngaged within said head and body, said bar having an end contaotable .with said movable 'aw a nlura-litv of ratchet teeth formed with the inner side" of said slida'ble bar, a lever tulcrum'ed in said casing, said lever having a plura"ty of teeth: engageable with the ratchet teeth upon said slidablebar, means for'inaintainformed with said head, a movable jaw operable within the slot in said head, means for engaging said movable aw therem, a; ratchet bar movable longitudinally within said cas ing, a head formed therewith adapted toenga'ge with said movable jaw, Imeans for operating said sliding bar, means for holding said sliding bar in operative position, means. for engaging said sliding'bar in an adjusted position, and means for disengaging said engaging means.
In testimony whereof I have affixed my signature;
. LEON eivrEwoRYns-KL Copies of this patent may be obtained for five cents each; by addressing the commissioner of Patents.
