Specification of Letters Patent. i
'Patented Feb, 2, 1909.
Application led January 27, 1908. Serial No. 412,836.
ATo all 'whom it may concern:
Beit known thatl, HERMAN A. PAQUETTE, a citizen of the United States, 'residing at Chicago, county ofv Cook, and State of lllinois, have invented certain new and useful Improvements inWrenches, of which the following is a specification.- v My invention relates to wrenches, and particularly to that class thereof characterized by a movable jaw slidably mounted u on the shank of a stationary jaw. lt is usua in wrenches of this form, to provide a screw for adjusting'the jaws, the screw also acting as a lock for the jaw.` To adjust a wrench of this kind takes considerable time, and usually requires both hands.
'lhe object'of my invention is to provide a wrenchy wherein the movable jaw may be readily and quickly adjusted Vbyv Vsliding 'it longitudinally on the shank of the stationary j aw by a single movement of the thumb, and
equiplthe same with means for quickly locking t e jaw after having been set.
A further obj ect of my invention is to rovide a wrench as mentioned, which shal be of simple construction, strong and durable, and one which will not readily get out of order. Other objects will appear hereinafter.
My invention consistsv generallyV in a wrench comprising a stationary jaw having a suitable shank, a movable jaw slidably mounted on said shank and adapted to be moved freely thereon, and means for locking said jaw against movement'.
My invention further consists in a wrench comprising a stationary jaw havinga suitable shank, a movable aw slidably mounted on said shank anda apted to be' moved freely thereon, co-acting lockingfaces upon said shank and said movablejaw, means normally holding said facesin yielding engagement, and means for positively locking Vsaid faces.
My invention further consists in various details of'construction and arrangementV of parts all as will bey hereinafter fully described and particularly pointed out in the claims.
My invention will be more readily under-VV stood by reference to the accompanying drawings forming a part of this specication and in which; f
Figure 1 is a side elevation of a wrench embodying my invention in its preferred form, Fig. 2 is a longitudinalsection through the movable head, the stationary head and theshank being shown in elevation, and the parts being shown` positively locked. Fig. 3
`is a similar view with the parts in unlocked position, illustrating the position they assume when 'the head is being moved longitudinally on the shank, and Fig. 4 is a cross-section on theline of Fig. 2. Y
vReferring to the drawings, 1 indicates the stationary head of the wrench iixed to the end of the shank 2, uthe said shank terminating in a suitable handle 3.
4 indicates the movable jaw. rThis is slidably mounted on the shank 2 and is provided with a sleeve `5 formed integrally therewith. rlhe front edge of the shank 2 is provided with a notched or ratchet edge 6 and the contiguous face ofthe sleeve 5 is provided with a similar co-acting face 7 near` its lower end. "lhe ratchet face 7 is preferably formed' upon a separate block 8 attached to the sleeve 5 by a screw 9.
10 indicates a lug or shoulder which bears against the block 8 relieving the screw 9 of vthe strain when the wrench is in operationf Directly opposite from the block 8 is a spring 11. This rests in-a recess 12 formed in the inner face of the sleeve 5 and bears against the shank 2 normally holding the ratchet faces 6 and 7 in yielding engagement. The spring 11 is formed of a strip of fiat spring metal bent into the shape shown and is held in the recess by a pin 13. The upper end of the sleeve iits the shank 2 quite snugly, the bearing faces 15 resting against the front and back edges of the shank. The inner front and back walls of the sleeve are cut away throughout the remainder of their length, permitting the-sleeve to move sufiiciently at its lower` end to withdraw the serrations of the face 7 from the serrations of the face `6, or, in other words, to disengage the ratchet faces.
To adjust the jaw, it is but necessary to shove on the lower rear corner of the sleeve with the thumb as indicated in dotted lines in Fig. 3. This presses the ratchet faces out of engagement after which it is obvious that the jaw 4 and its sleeve are free to slide lon the shank. i When the jaw is in proper position, the thumb pressure on the end 14 of the sleeve is released and the spring 11 again 'brings the ratchet faces into engagement. It is obvious that on account of the formation et' the ratchet faces, the jaws may be closed Without disengaging said faces; but to open the jaws it is necessary to disengage the faces as shown in Fig. 3. lt is also obvious that so long as the ratchet faces remain in engagement the jaws are locked against opening. However, the spring 1l is not of sufficient streng'th to hold them in engagement vfhen the Wrench is in use, especially if any great strain is placed upon the hande. Consequently it is necessary to provide auxiliary locking means to prevent disengagement et' the faces when in use. To this end, l provide a vfedge shaped cam block 16 and t' rm the rear Wall 17 of the sleeve With the inclined inner tace 1S lor cooperation therewith. By sliding the block 15 upwardly or toward t ie jaws, the faces 6 and 7 are positively locked. To operate the block 16 l provide a lever i9 pivotally mounted on a pin 2O arranged adjacent to the thumb piece 14. The lever comprises a sleeve 2l suitably drilled 'to roceive the pin 2G, a cani portion 22 which engages a notch 23 in the block, and a thumb piece 24. The lever ii mounted between the ears 25 on the sleeve 5 and is partly cut away as shown in Fig. i forming a recess 26 to accommodate a spring 27 interposed between one of the ears 25 and the end of the sleeve 2i. rlie spring 27 presses the opposite side of the lever against the adjacent lug 25 with suihcient force to prevent accidental displacement of the lever and the block i6. After the jaw l is in proper position the thumb piece 24 is drawn down by the thumb securely and positively locking the jaw against movement. When it is desired. to again adjust the jaw, the thumb piece is thrown inte the opposite direction, that is, in the position shovvn in Fig. 3, after which the aw' may be readily slid upon the shank as before.
Having described my invention what l claim as new and desire to secure by Letters Patent is:
l. A Wrench comprising a stationary jaw having a suitable shank, in combination With a movable javf slidably mounted on said shank and comprising the jaw proper and an integral sleeve, a ratchet face formed on one edge ol" said shank and a co-aeting ratchet face upon said sleeve at the opposite end from said jaw, said sleeve having a recess opposite said ratchet face, aspring arranged in said recess and adapted to bear against said shank to hold said ratchet laees in yielding engagement, a Wedge shaped cam block arranged between said shank and the rear Wall et said sleeve, said wall having an inclined portion for cooperating with said block, and inea-ns for moving said block to positively lock and unlock said ratchet laces as and for the purpose specified.
