Specification of Letters Patent.

Patented Oct. 23, 1906 Application filed March 1,1906- Serial No. 303,700-

Alabama, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

.Thetype of wrenches in common use is ob- Q jectionable for many purposes, owing to the to fact that it requires a large amount of time for the proper adjustment of the jaws, and the quick-acting-wrenches which have been hitherto designed do not permitas fine an adjustment as is frequently necessary.

The object of thepresent invention has accordingly been to design a wrench which embodies in one tool the great advantages ofthe two types of wrenches just mentioned. For this purpose the movable jaw of the wrench is provided with a block one face ofwliich isthreaded so as to engage with the threaded I adjusting-rod, said block beingl slida'bly mounted, so as to be quickly move.

with the adjusting rod for anyconsiderable distance.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of 0 the means for effecting the result'reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view of the wrench. Fig. 2 is a side elevation of the same, parts being broken away and shown insection. Fig. 3 is a transverse sectional view. Fig. 4 is a longitudinal sectional view through a portion of the wrench and shows the blocks as disengaged from the adjusting- Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 designates the shank of the wrench, which is provided with a fixed jaw 2 of the conventional type at one end and the opposite end. The handle 3 is formed. with a lug 4 at the inner end thereof, which serves as a bearing for the ad'usting-rod 5.' This threaded adjusting-r0 5 extends longitudinally along the shank 1 and has one end mounted in the fixed jaw 2, while the opposite end is mountdinthelug 4...

l the block 9 out face of the shank 1 adjacent the adjustingrod 5 is formed with a groove ordepression which receives the inner portion of the adjusting-rod and serves as a guard to exclude dirt or other foreign matter. A thumbpiece 6 is formed. inte ral with the adjustingrod 5', and this thum j-pieceis shown in the drawings as bein located adjacent to the handle 3, so as to e readil accessible. The movable jaw 7 is secure to or preferably made integral with a sleeve 8, which is slid ably mounted upon the shank 1 and also fits over the adjusting-rod 5. A block 9 is mounted in one side of sleeve 8, so as to engage with the threaded adjusting-rod, the face coming into contact with the said rod being formed with a longitudinal. depression which is threaded so as to cooperate with the threads upon the rod 5. The ends of the block 9 are provided with tongues 10-, which slide in corresponding grooves in the sleeve 8. This construction revents any lateral displacement of the b ock 9, but enables the block to be moved in and out of engagement with the rod 5. This block 9 is connected to the movable jaw 7 b means of linkmembers 11, one end of whic are pivoted .to said jaw, while the opposite ends are pivoted to the block by means of a'pin 12. The extremities of the pin 12 preferably project beyond the sides of the wrench and are formed with fingerieces 13, which are preferably knurled, as s own. When thus constructed, it will be apparent that by gras ing the finger-pieces 13. the block 9 can he moved out of engagement with the threaded stem 5 and the movable required position it can be accurately adthe thumb-nut 6 in the justed by turnin t will thus be understood usual manner. that by employing rod 5 the movable jaw 7 can be very accurately adjusted, while be quickly moved to any desired position u on the shank 1. A finger-lever 17 may ,a so be employed when desiredfor throwing of engagement with the ,adno In the preferred form ofthe invention the the threaded adjustingby disengaging the :05 block 9 from the rod 5 the movablejaw can sides of the block, each of the link members having one end ivotally connected to the movable j aw, whi ethe opposite end is loosely connected to one of the projecting ends of the 4 5 before-mentioned pin, and means for holding the block normally in engagement with the adjusting-rod. I

3. In a wrench, the combination of a shank, a fixed jaw rigidly connected to one end thereof, a handle at the opposite end thereof, a threaded adjusting-rod extending along the shank and mounted between the fixed jaw and the handle, a movable jaw formed in connection with a sleeve which is slidably mounted-upon the shank, a block loosely mounted in one side of the sleeve and adaptjed to engage with and cooperate with the threaded adj usting-rod, a pin passing through the block and having finger-pieces at the extremity thereof, the said fingerepieces serving as a means for lifting the block out of engagement with the threaded adjusting-rod, a pair of link members located upon opposite sides of the block, each of. the link members having one end pivotally.connected to the (movable jaw, while the opposite end is g'loosely connected to one of the projecting exv ftremities of the before-mentioned pin, means for holding the block normally in engage- 7o ment with the threaded adjusting-rod, and a finger-lever pivotally mounted upon the sleeve and engaging-with the block to form a second means whereby the same can be lifted out of engagement with the adjustingrod.

In testimony whereof I aflix my signature in presence of two witnesses.

justing-rod 5. This lever 17 is shown as pivotally mounted between lugs 15, projecting outwardly from the sleeve -8, the rear end of the lever forming a finger-piece, while the 5 forward end fits in a recess 16 in the block 9 and engages with said block to pull the same away Irom the threaded adjusting-rod when pressure is exerted upon the finger-piece,

Having thus described the invention, what I0 is claimed as new is 1. In a wrench, the combination of a shank, a fixed jaw rigidly secured to the shank, a threaded adjusting-rod extendingalong the shank a movable. jaw formed in connection 1 5' with a sleeve whichis slidably mounted upon the shank, a block loosely mounted in one side of the sleeveand adapted toengag'e with the before mentioned threaded adjustingrod, the said block being formed at opposite 2o. ends with tongues which operate in. corresponding slots in the sleeve and prevent lateral displacement of the block, link members loosely connecting ftheblOckto the movable j aw, a spring for normally holding the block 25 1n engagement with the adjusting-rod, and a finger piece for withdrawing the block from engagement. with theadjusting-rod.

2. In a wrench, the combination of 'a shank, affixed jaw rigidly secured to the shank, a go threaded adjusting-rod extending along the shank, a movable jaw formed in connection with a sleeve which is slidably mounted upon the shank, a block loosely mountedin one side of the sleeve an adapted to engage with,
