GHARLS B. GREEN, OF ST. PAUL, MINNESOTA.
WEE NCH.
Application le February 24, 1908.
To all whom it may concern:
Beit known that l, CnnnLns B. GREEN, a citizen of the United States, residing at St. Paul, in the county of ltamsey and lState of lvlinnesota, have invented certain new and useful improvements in l/Vrenches, of which the following is a speciiication.
My invention relates to improvements in wrenches and has for its objectl to provide a wrench having improved means for tightening and holding the jaws upon the nut or other object to be turned or held and for releasing the jaws therefrom; also to provide an improved form of jaw and improved means tor manipulating the wrench head, and in general to provide a wrench which shall be simple oi construction, positive in operation and easy to manipulate.
More particularly the invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.
ln the accompanying drawings forming part of this speci'lication, Figure l is a perspective view of the improved wrench looking towards the back or top thereof Fig. 2 is a side elevation of the wrench, showing the spring 'linger forced up out of engagement with the toothed dish Fig. 3 is a longitudinal section through' the middle oi the wrench on line fc-x of Fig. 1 Fig. Il is a plan viewoi the toothed disk alone 5 Fig. 5 is a plan view of the slotted plate which carries the guide racks for the jaws Fig. 6 is a bottom view of the slotted plate and jaws, Figs. 7, 8 and 9 are top, side and bottom views, respectively, of one of the sliding j aws; Fig. 1() is a bottom view of one of the jaws and a fragment oi the guide raclr upon which it works, and Fig. 11 is a bottom view of the handle and the annular head carried by it.
ln the drawings 2 represents the wrench handle. This terminates in an annular head 3 having a downwardly extending annular lug or flange d. The head its over, and is journaled upon, the hub 5 which is carried by the slotted plate 6. lt is held upon the hub by means of a bearing nut 7 threaded upon the Lipper or outer end of the hub and downwardly beveled to torni a bearing suriace for the correspondingly beveled top oi the head. Also rotatable upon the hub 5 and retained by the annular head is a toothed disk 8 having notches 9 to receive the spring vlinger l0 carried by the handle. rl`he toothed dislr` is formed on its upper face with Specification of Letters Fatent.
latented Feb. 9, 1909.
Serial No. 417,323.
arried by the toothed dislr 8, and secured thereto by means of studs 13, which pass through the slots 12 in the plate 6, and through holes 1d in the toothed disk are oppositely disposed jaws l5. As shown in the drawings the studs 1.3 are integral with, or secured to, the jaws at one end thereof, and are secured to the toothed disk by means of nuts 17 upon their upper ends. Thus, when the toothed dislr is turned by means of the handle, the studs will travel in the slots 12 and bring the jaws together, as illustrated in Fig. 6. Each jaw is formed with an angular or inturned liange 18, so as to engage two sides of the nut or other object to be held or turned.
As the toothed dislr operates only on the studs or posts 13 at one end of the jaws, any object gripped will tend to swing the other ends thereof away from each other as the handle is turned. To overcome this two oppcsitely curved radially disposed toothed racks 19 are secured upon the under face of the plate 5, shown in Fig. 6, and the under tac-e ol' each of the jaws is formed at its tree end, that is the end opposite the stud. or post 13, with a curved groove or channel 20. to receive within it the curved rack 19. Now, when the handle is turned, the rack, arranged within the groove or channel in the jaw will hold the j aw from being swung out, and will cause the two jaws to travel in parallelism toward each other, while the teeth of' the rack will prevent the free end of the jaws from being crowded bach or from turning the plate. lll-.Then it is desired to separate the jaws the direction of rotation ci" the dislr is reversed. This will throw the jaws out of engagement with the teeth of the rack and will torce the curved sides of the groove 2O against the curved outer side 21 oi the rack thus causing the jaws to travel in parallelism away from each other. lt will be observed that the jaws are moved, not only toward and away from each other, but also endwise,
so that the hangular ilangeshatwtheir ends are brought together and tightened upon the object to be gripped.
The spring :linger 10, as shown in the drawings is carried by a spring strip 22 secured upon the underside of the handle by lasterf ings 23, and Worked between guide-lugs 2d upon the under side ol' the handle. At its forward or tree end it has an upwardly projecting arrn 25 extending through a hole in the handle. The linger l() 1s held by the resiliency ol its spring 22 normally sprung down into er ent with the toothed disk, as shown in To prevent the linger i'roin pressing again t the plate 6 the'arin is provided the top with a lip or ilange Which serves as a stop to engage the upper side of the handle and liniit the spring actuated nio'venient of the linger.
rllhe operation the ure h, Yvhi ha already been erpluned in connection with the delcription oV he construction, nay be sunnnariaed as follows: rllie spring linger l0 upon the underside of the handle is held by the resilience ci its spring 22 normally pressed down into one ciI the notches ci the toothed disk 8, whereby the handle is operatively connected 'with the disk, so that the disk will be turned with the l'iandle. To adjust the iaws to the nut or other object to be operated upon, the handle is turned in one or the other direction, according as separation or contraction oi' the jaws is desired. lllhen the handle is turned to contract the jaws, the studs carried by the disk vJill travel towards each other in the slots 12 and bring the jaws togetner, as above explained, the toothed racks arranged upon the underside of the plate 6, and working within the grooyes 2O in the jaws, serving to hold 'the :s in parallelisin, as heretofore explained. v",r'l'ien the handle is turned in the opposite direction the studs fill travel away lroni each other in the slots 12, thus separating the Ws the stud ends and at the saine time throwing the free ends oi the javfs out of engagement with the teeth` oi' the rack, While the pressure oll the curve(L sides ci the grooves 2O against the curved outer sides 21 of the racks will keep the jaws in parallelism. Alter the wrench has been adjusted to the nut or other object, it is operated in the ordinary Way. lt will be observed, however, that the curved racks, the teeth of .rhich are set Aist the free ends of the s, as illustrated in llig. 1G, vwill hold the jaws from being forced back under the pressure exerted in turning the Wrench. l/Vhen it is desired to turn the handle to take a fresh grip upon the disk without releasing the javfs, it is only necessary to press the spring strip 22 up towards the underside of the handle. The strip will carry the 'linger l0 up out of engagement with the toothed disk and perinit the handle to be turned ciali? Without also turning the disk and the jaws' carried thereby. Eeing arranged upon the underside ot the handle, the spring can be operated by the lingers With perfect ease and sureness Without releasing tneir hold upon, the jaws or requiring any unusual inovenient.
vlarious changes inay be inade in the details of the structure Without departing from 'the principle of the invention the scope ol which is defined in the claii'ns.
l claini as n'iy invention:
l. ln a wrench of the class described, in conibii'iation, a Wrench head and a handle caU 'ed thereby, a notched jaw-carrying disk rotatable upon the wrench head, a spring strip arranged lengthwise of the handle and secured at one end upon the underside therea 'in ger carried by the strip at its free end 1d having an upwardly extending arni passin freely through the handle, the Ylinger being held by the strip normally drawn down into the .notches oi' the disk and operatively connectir the handle and disk, but being raised out et said notches `when the strip is pressed rp, and stop carried by said armV upon the upper side oi the handle to engage the handle and liniit the spring actuated rnoveinent el' the linger.
2,. ln a Wrench of the class described, in combination, a Wrench head and a handle carried thereby, a toothed disk rotatable in tli ,Wrench head, a plate also rotatable in the uf'rench head upon the under tace of the disk, and formed With oppositely disposed curved slots, said plate also having oppositely curved radial racks upon its under face, a pair oi oppositely arranged aWs slidable upon said racks, and a stud passing through each of the slots in said plate and connecting the atvs With the toothed disk, for the purpose set forth.
