assembled or disassembled as well as reenewed in'the event of breakage or wear.
Other objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.
In the accompanying drawings: 7
Figure 1 is a longitudinal sectional view of the preferred embodiment of this invention showing the wrench handle and coacting jaw in elevation;
Figure 2 is a transverse sectional view on the line 2-2 of Figure 1;
Figure 3 is a side elevation; v
Figure 42 is alongitudinal sectional v1ew of a modified form of the invention;
Figure 5 is a transverse sectional view on the line 55 of Figure 4;; and
Figure 6 is a bottomplan view of the form of wrench shown in Figure 4.
Like referencecharacters designate corresponding parts throughout the several figp ures of the drawing.
Referring to the preferred form .ofiny invention as disclosed in Figures 1 to 3; A-
designates the relativelymovablejaw and B the relatively stationary jaw. The former is composed of the jaw 1 proper, which is removably mounted through the instrumen-,
tality of the rivet 2 inthe perforate extremity of the channel pieceB which constitutes,
the shank of the jaw and a housing or guide for the parts of the wrench construction, as will be more clearly apparent as this description proceeds.
The jaw B is formed at one sideiwith a cylindrical boss or key-extension 4 which freely fits in the correspondingly. shaped socket or channel 5 in the end .of the handle being maintained by virtue oflthecoopera tion of the surrounding sides of the channel The gas B obviously thus permitted to have a certain degree of rotation, relative movementsof the handle and jaw being made possible. A spring 6 riveted to the band 7 at 8 bears against the jaw and tends to hold it against the base of the shank channel. I I This freedom of movement is particularly important in the preliminary adjustment of. the jaws on the object to be gripped, the entrance to the jaw being enlarged by pres s ing the outer end of the jaw B againstthe object and thereby rotating it until abutment with the shoulder extremity 9 of the handle which acts to shiftthe jawin theopposite direction, upon rotation of the hang dle. Such rotation forces the jaw B firmly against the object and the biting action becomes immediately effective.
In this form of the Wrench the band? extends completely around the shank 3 and the handle C and is provided with an aper ture 10 receiving the boss 11011 the base of the'handle. This interengagement constitutes an interlock; which holds the parts of the wrench in assembled condition.
Atone sidev the handle is providedwith one way. acting teeth 12 with whichv the 1' having a depre ssibl e operating finger piece 14 positioned at the end of the shank 3 where it is. readily accessible to .thehand grasping the handlep C. The pawl is piv otally mounted: on the removable pin 13 ass ing through the sides of the shank 3.
The handle C isformed with the head extension 15 which fits into the channel of the, shank and cooperates with. the boss 4 thereof to producea clamping action'upon the shank which lies bet-ween said extension and :the band, a'very important feature of this construction. That is' to say, when the pressure is exerted against the handle for turning theobject engaged, said handle rocks about the projection 11 until the. extension 15 engages withthe shank 3, forcing thelatter against the band 7. Simultaneously;
of course, the jaw B is forced into-bitingz-f tional clamping action just referred to in creases 1n proportion to the amount of pres engagement with the object and the frici sure exerted and the strain which would, a
otlierwisefall'uponthepaw1'13 is substantiallyentirely removed therefrom;
, In general, the operation t the fellowsi pawl 13 beif lg from the rack teeth 12 by the thumb, the' jaw A is shifted freely outwards until the proper opening of the jaws is obtained. With the jaw B held against the object, the jaw A is now pressed back by the other hand until engaged with the object at the opposite side of the jaw B, the previously released pawl 13 sliding freely over the teeth 12 in this adjustment.
This is easily and quickly accomplished and then the handle C is rotated causing the extremity 9 to act against the jaw B and at the same time producing the clamping action on the shank 3 as hereinbefore described.
The form of the device which is illustrated in Figures 4: to 6 differs slightly from the preferred embodiment but operates on exactly the same principles. The several parts which correspond in these figures are therefore given the same reference numerals. In this form of the wrench I substitute for the band 7 a yoke 7 which is connected to a pin 16 passing through the inner end of the jaw B and the handle C being removably held bya cotter key 17. A flat leaf spring 18 secured to the handle C at 19 bears against the under edge of the jaw B tending to force it into the position shown in Figure 4, but permitting pivotal swinging movement of said jaw about the pin 16. At the top of the aw an extension 20 is provided and extends into the channel shank piece 3 guiding the aw in its pivotal move ment. In this form of the device and in the preferred embodiment, the head15 of the handle C contactswith the shank piece where indicated by the arrow 21 to cause a clamping action of the shank against the yoke 7.
With respect to either of the wrenches hereinb'efore described the jaw members may be easily removed whenever it is necessary to replace the same on account of breakage or repair and the cost of such replacement Would be nominal as compared with the re-.
placement of the whole wrench as is required in most instances of present day construe v Having thus described my invention, what I claim as new and desire to secure by Letters' Patent isz' 1. In a wrench, a handle, a jaw member swingingly' connected thereto, a second jaw member having a channel-shaped shank in which to s'lidingly receive the first jaw and handle, means adjacent the inner end of the handle to elampingly engage said shank, and means ear'ried by the shank and engageable with the handle' to hold the jaws at adjusted position.
2. In av wrench, a handle havin an abut ment, a jaw member pivotally connected thereto to swing into engagement with an abutment on the handle, a sliding jaw member, a yoke engaging about said jaw members and handle, and a pawl mounted on the sliding jaw member and engageable with the handle to hold the parts at adjusted position.
' 3. In a wrench, a handle, a jaw member connected thereto, a cooperating jaw memher having a channel-shaped shank in which the handle and first mentioned jaw member are received, and a yoke member embracing the shank and movably connected to the handle to hold the parts assembled, said handle having means cooperative with the yoke to frictionally clamp the shank when the handle is rotated to impart gripping action on the object engaged between the aw members.
4:. In a wrench, a handle, a jaw member mounted thereon, a. second jaw member having a shank slidable relative to the first jaw and handle, means carried by the shank and engageable with the handle to hold the jaws at adjusted posit-ion, a member embracing the shank and handle and providing a pivot for the latter, and means adjacent the inner end of the handle to clampingly.
member having a channel-shaped shank engaging about the first mentioned jaw member and handle, a support embracing said shank and handle and providing a pivot for the latter, and latching means within the channel of the shank and engageable with the handle for holding the jaws at adjusted position.
7. In a wrench, a handle, a jawhaving pivotal connection with the end thereof, a second jaw member having a shank extension, a yoke connecting said second member with the handle, there being an ex tension upon the handle for clamping said shank and yoke in engagement, a locking pawl carried by the shank extension and engageable with the handle, and a spring coacting with the first mentioned jaw men'r ber.
In testimony whereof IaffiX my signature. 7
