Specification of Letters Patent.
Patented Feb. 12 1918.
Application filed December 19, 1917. SerialNo. 207,908.
- T 0 all whom it may concern:
, ments in wrenches and has relation more' Be it known that I, FRANK FEssLEu, a citizen of the United States, residing at Woodbridge, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in WVrenches, of which the following is a specification, reference being had to the accompanyin'g drawings.
vThis invention relates to certain improveparticularly to a device of this general charact'er of a rigid jaw type and it is an object of the invention to provide a wrench of this general character with novel and improved means whereby the jaws may be readily and conveniently applied or removed so that the wrench may be employed with work of different sizes.
It is also an object of the invention to provide a device of this general character,
having novel and improved means whereby a rigid jaw may be securely maintained in applied position upon a handle or shank and whereby-the same can be removed with facility when the occasion of practice re-' quires. I
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved wrench whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will nowproceed to describe thesame with reference to the accompanying drawings wherein:
Figure 1 is a view in side elevation with a portion broken away of a wrench constructed in accordance with an embodiment of my invention;
o 0 o a Fig. 2 1s a view 1n top elevation of myimend portion in section; and
Fig. 3 1s a view 1n elevation of a series of jaws ashere1n employed and which are proved wrench as herein embodied with one adapted to be interchanged.
As disclosed in the accompanying draw-- ings 1 denotes a handle or shank substan tially S-shape or sigmoidal in form and which has each of its opposite ends inbowed as at 2 and the transverse center of said -in-.
bowedend 2 is provided with a recess or channel 8 extending substantially entirely therealong. The opposite faces of the handle or shank l at each end portion thereof are provided with the elongated and longitudinally disposed recesses 4 having their outer ends flared and open at the outer end thereof. Bridging each of the recesses 4 at a predetermined point inwardly of its inner end is a cross member 5 which is preferably flush withthe adjacent side face of the handle or shank l and spaced from the bottom of the recess 1:.
J denotes a rigid jaw of a conventional type having the inner portion 6 thereof outbowed as particularly illustrated in F ig. 1 and adapted to snugly fit within the inbowed end portion 2 of the handle or shank 1 and said outbowed portion 6 at the transverse center thereof is provided with the outstanding rib or flange 7 adapted to snugly fit within the groove or channel 3 hereinbefore referred to. The 'side facesof the jaw J at the transverse center thereof areprovided with the rearwardly directed spring or resilient arms 8 adapted tosnugly fit within the recesses 4.' Each arm 8 .re
depth as 'to permit the arm 8 to be'forced I inwardly a dist'ance sufiicient to permit the disengagement of the arm 3 from the cross piece 5 when. it is desired'to remove the jaw J.-
The opposite ends of the outbowed portion 6 of the jaw J is defined by. the shoulderslO,
having t ieir opposed faces indiverging 're 'lation and which are adapted tbgoverhe or contactwith corresponding faces lL-ntfthe opposite ends of the inbowed portion .2
whereby the strain imposed upon the j m. J durin the working operation is direct y upon the handle or shank- 1.- iindj hespring arms 8 relieved th'erefrom.:, ",g': 4 y
In. practice it is intended that;
handle or shank 1 a plurality of jaws-'J are" adapted to be employed, said jaws being .of
different sizes to compensate-for. difi'enent sizes of work and-in view-of the foregoing description it is thought to be self-evident that the jaws J may be readily and conveniently interchanged when the requirements of practice may necessitate. It is also preferred that the handle or shank 1 be gradually decreased in thickness from one end. toward the other as indicated in Fig. 2 so that the jaw J mounted upon one end of the handle or shank 1 may be employed in connection with smaller work than the jaw atthe oppo'site'end of the handle or shank 1.
From the foregoing description, it is thought to be obvious that a wrench constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility withwhich it may be assembled and operated and it will also be obvious that myinvention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
I claim:
1. A wrench comprising a shank having open recesses in opposite faces thereof, a cross-piece bridging each of said recesses intermediate the length thereof, a jaw, and spaced spring arms extending from the jaw and seatable within the recesses of the shank, said arms being provided with shoulders to contact with the inner edges of the crosspiece.
2. A wrench comprising a shank having open recesses in opposite faces thereof, a cross-piece bridging each of said recesses in "termediate the length thereof, a jaw, and
spaced spring arms extending from the jaw and seatable within the recesses of the shank, said arn'isbeing provided with shoulders to contact with the inner edges of the cross piece, the opposed faces of the jaw and shank, when the jaw is in applied position, being provided with an interlocking rib and groove.
3. A wrench comprising a shank having open recesses in opposite faces thereof, a cross-piece bridging each of said recesses in termediate the length thereof. a jaw, and spaced spring arms extending from the jaw and seatable within the recesses of the shank, said arms being provided with shoulders to contact with the inner edges of the cross piece, said jaw at opposite sides of the arms being provided with inwardly directed shoulders overlying adjacent faces of the shank.
4. A wrench comprising a shank having open recesses in opposite faces thereof, a cross piece bridging each of said recesses intermediate the length thereof, a jaw, and spaced spring arms extending from the jaw and seatable within the recesses of the shank,
said arms being provided with shoulders to contact with the inner edges of the cross piece, the opposed faces of the jaw and shank, when the jaw is in applied position,
being provided with an interlocking rib and groove, said jaw at opposite sides of the arms being provided with inwardly directed shoulders overlying adjacent faces of the shank.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
FRANK FESSLER.
