SPECIFICATION formingpart of Letters Patent NO. 684,233, dated October 8, 1901. Application filed January 28, 1901. Serial No. 45,7104. (No model.)
A T all wwnt it may concern:
Be it known that LYWILLIAM THOMAS HAT- TEN, a citizen of the United States, residing at Heppner, in the county of Morrow and State of Oregon, have invented a new and useful Vrench, of which the following is a specification.
The present invention relates to wrenches, and particularly to that class having a lixed jaw and a sliding jaw that can be moved toward and away from said xed jaw for the purpose of fitting the wrench upon nuts or pipes of different sizes.
The object of the invention is to provide novel means for locking the movable jaw in fixed relation, said means being constructed so that a variable adjustment can be obtained and when positioned is held rigidly against retrograde movement.
To the accomplishment of this and other objects, the construction shown inthe accompanying drawings and described in the following specitication is preferred; but it will be readily understood that such construction is open to slight change and modication within the scope of the appended claims.
In the drawings, Figure 1 is a side elevation of the wrench embodying the present improvement. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a crosssectional view taken on the line :c a; of Fig. 2. Fig. et is a detail perspective view of the locking-clutch.
Similar numerals of reference designate similar parts throughout the several figures of the drawings.
The usual shank 10 is provided, forming at one end a handle and provided at its other with a transverse head 11, having a fixed jaw 12. Slidably mounted upon said shank is a movable jaw 13, which is arranged to coact with the fixed jaw l2. This jaw is provided with a loop 1i, through which the shank 10 passes, and it also has an arm extension 15, which is disposed longitudinally of and contiguous to one side of the shank 10, said eX- tension being provided at its end with an offset hinge-ear 16, to which is pivotally secured a clutch-loop 17.
The clutch-loop 17 is in the form of a bel1- crank lever having the two arms 18 and 19. The arm 19 is provided with a transverse opening 20, forming the clutch-loop through which the shank 10 passes. An opening 21 is also provided at the elbow for the reception of the hinge-ear 16, and a pintle 22 pivotally connects said ear and loop. By this construction an intermediate partition 172L is provided, which is arranged to bear against one side of the shank 10. That portion of the -wall of the opening 2O which is on the opposite side of the shank 10 from the partition 17a is provided with a knife-edge 23, arranged to engage the face of the shank, which face is preferably smooth. This knife-edge is preferably arranged upon an insertible tooth 24, secured iu the wall of the loop, whereby some hardened metal, as toolstee1, may be used that is not liable to wear. Furthermore, this tooth is in the form of an equilateral triangle in cross-section, so that should one edge become worn the tooth may be removed and inserted with a new edge in operative relation. The offset arm i8 is arranged over but spaced from the arm extension 15, and said extension vis provided with a socket 25, in which is seated a coiled spring 26,the outer end of which bears against the Linder side of the arm 18, thus urging said arm away from the extension 15, and consequent-ly pressing the knife-edge 23 into engagement with the shank 10.
The operation of the device will be obvious. The shank l0 is normally clamped between the partition 172L and the knife-edge 23.
To adjust the movable jaw, it is only necessary to press upon the offset arm 18, which forms a finger-grip for that purpose, whereupon the knife-edge and partition will be disengaged from the shank 10, and the jaw may be freely moved in either direction. When the proper adjustment has been obtained, the arm 18 is released, whereupon the knife-edge will be brought into engagement with the shank 10 and the sliding jaw held rigidly against movement.
This construction greatly simpliies this class of wrenches and provides locking mechanism that can be readily operated and easily understood. By providing the operatingarm v18, against which the spring bears, a greater leverage upon the clutch-loop is obtained, thus insuring a binding engagement between it and the shank and also making it .easier to be disengaged therefrom. Further- ICO more, by the use of the reversible tooth 24 the life of the Wrench is greatly prolonged.
From the foregoing it is thought that the construction,operation,and many advantages of the herein-described invention will be apparent to those skilled in the art Without further description, and it Will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.
Having thus described the invention, what I claim is- 1. In a Wrench, the combination With a shank carrying a jaw, of another jaw slidably mounted upon the shank and having an arm extension, a clutch-loop pivotally mounted upon the arm extension of the sliding jaw and adapted to engage the shank to hold said sliding jaw against movement, said loop being provided with an oset arm located adjacent to the arm extension, and a spring interposed between and bearing against the offset arm of the clutch-loop and the arm extension of the sliding jaw to move said loop into engagement with the shank.
2. In a Wrench, the combination with a shank carrying a jaw, of a jaw movably mounted upon the shank and having an arm extension, a bell-crank lever pivotally connected at its elbow to the free end ot' the arm extension, one arm of said lever being in the form of a clutch-loop that surrounds the shank and arranged to engage the same to hold the jaw against relative movement, the other arm forming an operating-handle and being located adjacent to and spaced from the arm extension, and a spring interposed between i and bearing against the arm extension and the operating-handle to hold the clutch-loop in engagement With the shank.
3. In a wrench, the combination with a shank carrying a stationary jaw at one end, Y
of a movable jawslidably mounted upon the shank and having an arm extension, the free end of which has a hinge-ear, a bell-crank lever pivotally connected at its elbow to the hinge-ear, one arm of said lever being in the form of a clutch-loop that surrounds the shank, a removable tooth carried by theV clutch-loop and having a plurality of engaging edges each of which may be moved to an operative position to engage the shank, the
other arm of the bell-crank lever forming auV operating-handle arranged contiguous to but spaced from the arm extension, and a coiled spring the shank.
4. In a wrench, the combination with a I n `the presence of two witnesses.
