' Dec. 12, 1944. L. c. NEWBERRY 2,365,139 WRENCH v Filed March 31, 1945 ,2 Sheets-Sheet l [LY/V; when Swim/Wm Patented .Dec. 12, 1944 UNITED STATES FATE NT. OFFICE WRENGH' LawrenceO. Newberry, Long Beach, Calif.

' Application March 31, 1943;}Serial No; 4811309 4- Claims. (191. 81-102)! 9 This-invention relates to a wrench, especiallyone capableof use either as a pipe wrench oras a monkey wrench; v

It is aimedto" provideja construction which isquickly adjustable, durable; and eificient and which especiallyhas a saddle slida'bly mounted on onejaw carrying the other' jaw for'tooth enigagement with the first jaw, 'to which secondjaw a handle is) pivoted as'wellias to the saddle and on which the wedge'lockis slidably mounted to coact' with: the handle and the-second-mentioned jaw.

The more specific objects and; advantages. will become apparent fromthe descriptionfollowing taken in connection withacc'ompanying drawings illustrating an operative embodiment.

In said drawings:

Figure l is a view in elevation of a wrench constructed in accordance with the invention;

Figure 2 is an edge view of said wrench;

Figure 3 is an enlarged view of the major portion of the wrench, parts being in section to disclose details;

Figure 4 is a view of the parts similar to Figure Figure 6 is a detail section taken on the line B6 of Figure 3; and

Figure '7 is a detail section taken on the line 'l'l of Figure 3.

Referring specifically tothe drawings wherein like reference characters designate like or similar parts, a U-shaped saddle is provided at IU which approximately houses the main jaw or block H; A pin l2 bridges the side walls of the saddle and passes through an enlarged opening l3 in jaw block II. The latter will move longitudinally with the saddle, but is capable of movement toward and away from the bridge of the saddle.

The outer or movable jaw generally designated l4 also is mounted by the saddle l0, having a shank I5 passing slidably through the saddle between its bridge and the jaw block ll. Jaw M has a head at l6 provided with teeth or serrations at I! to coact with pposed teeth or serrations l8 on the jaw block I l. The inner longitu-v dinal face of the shank l5 has ratchet teeth or I serrations at [9, while the opposed face of the jaw block II has similar ratchet teeth or serrations at 20.

Normally the teeth l9 and are disengaged and spaced as shown in Figure 3, as spacer pins 2! are slidably mounted in recesses 22 inthe jaw bl'ock"|l',;agains t the expansive action of coil spring 23; 'Theoutcr or free endsof the spacer, pins 2| are preferablysphericaland abut the teeth'l9 andfare freely slidable thereover, .preventin'g,normally, contact of the. teeth 29 with the teeth I9. I

The free end ofxshank l5 is'recessed and fitted. therein'with a stop element 25, a screw 26 securing it in. place. This stop .element is adapted for abutmentwith'the bridge of the saddle ID. to

prevent accidental detachment of the'movable at 30 said end of the handle 21 is pivotally connected to the jaw block. It will be noted that there is suflicient clearance between the inner end of handle 21 and the walls of the recess 29 to enable the handle ,2! to be rocked on the pivot 28 and move the block into and out of position and I 9 engaged, a slide 3| is provided. This slide is dovetailed at 32 in order to slidably fit a dovetailed or undercut groove 33 provided in one edge of the operating lever or handle 21. One end of the slide 3| has a wedge 34 thereon and the other end is enlarged at 35 to provide a fingerpiece.

Normally the movable jaw 14 and main jaw H are free to slide to different adjustments in order to engage work such as a pipe P shown in Figure 4. Such adjustment is quickly attained since the jaw l I is moved through longitudinal movement of the handle 21 or the jaw M is longitudinally moved relatively thereto; When the desired ade justment is attained,'ha'ndle 21 is rocked on the lever 28, thereby through its pivotal connection at 30 with the jaw ll sliding the latter toward the shank l5 and engaging the teeth I9 and 20, with the pins 2| receding into the recesses 22 and compressing the spring 23, following which, the slide 3! is moved along the handle 21 and the wedge 34 thereof is brought into engagement with the adjacent wall of the recess 29 so that the jaw II will be locked in the position mentioned and the lever 2'! will be locked against movement on the pivot 29. Thereupon the handle 21 is moved in the usual manner of a pipeor monkey-wrench with respect to the work P. It is clear that the wrench is capable of use as both a monkey wrench and a pipe wrench.

Various changes may be resorted to provided that they fall within the spirit and scope of the invention.

I claim as my invention:

1. A wrench comprising a saddle, a jaw slidacie therein, a jaw block, means mounting the jaw block for movement with the saddle and for movement independently of the saddle into and out of engagement with the jaw, said jaw block having a recess, a lever pivoted to the jaw block within the recess and to the saddle operative to effect the last-mentioned movement, and means to secure the handle and block against relative movement when the block is engaged with the jaw, comprising means slidable into the recess to bridge the space between the lever and the opposed wall of the recess.

2. A wrench comprising a saddle, a jaw slidable therein, a jaw block, means mounting the jaw block for movement with the saddle and for movement independently of the saddle into and out of engagement with the jaw, said jaw block having a recess, a lever pivoted to the jaw block within the recess and t0 the saddle operative to effect the last-mentioned movement, and means to secure the handle and block against relative movement when the block is engaged with the jaw, comprising means slidable into the recess to bridge the space between the lever and the opposed wall of the recess consisting of a wedge slidably mounted on the lever.

3. A wrench comprising a saddle, a jaw slidable therein, a jaw block, means mounting the jaw block for movement with the saddle and for movement independently of the saddle into and out of engagement with the jaw, a lever pivoted to the saddle and to the jaw block operative to effect the last-mentioned movement, and means to secure the handle and block against relative movement when the jaw and jaw block are engaged whereby the jaw and jaw block will be locked together, consisting of a wedge means slidably mounted on the handle, the block having a recess into which the wedge means extends and the wedge means being of dovetail cross section engaged in a groove of similar shape in the handle.

secure the handle and block against relative movement when the jaw and jaw block are engaged whereby the jaw and jaw block will be locked together, consisting of a wedge means slidably mounted on the handle, the block having a recess into which the wedge means extends and the wedge means being of dovetail cross section engaged in a groove of similar shape in the handle, a pin spanning the saddle, the jaw block having a slot through which the pin extends, interengageable teeth between the jaw and jaw block, and spring-pressed means on one of said parts normally engageable with the other and the teeth thereof to prevent interengagement of the teeth.
