SPECIFICATION forming part of Letters Patent No. 442,190, dated December 9, 1890.- Application filed April 4;, 1890. Serial No, 346,598. (No model.)
lT0 all whom, t may concer/L.-
Be itknown that I, JOHN ll. LANE, of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in lVrenehes, ol' which the following is a specification.
My invention relates to wrenches; and the object of my improvements is to provide a wrench f or tightening the spokes of bicyclewheels, and that is adapted to grasp a straight er conical nipple. l attain this object iu the device shown in the aceompan yin g drawings, in Which- Figure l is a side elevation. Fig. 2 is a plan view looking from the top. Fig. 3 is a plan view looking from the bottom; and Fig. -Lt is a side elevation, partly in section, the jaws being drawn apart.
Similar letters refer to similar parts throughout the several views.
A is a sleeve closed at one end and provided with internal screw-threads. N is an annular groove formed in the internal surface of said sleeve near its open end.
The sleeve A forms the handle of the wrench. One jaw of said wrench consists of the rectangular head B, provided with a semicylindrical shank b. The other of said jaws consists of the rod D and the head C, said head being pivoted to said rod at its upper surface at its end by means of the screw F.
G is a lug extending downward from the lower surface of the head C into a slot ll, formed in the rod D. The slot Il has the shape of the are of a circle whose center is the screw F. The lug G limits the turning motion of the head C by striking against the ends of the slot lL The rod D is pivoted at cl to the semi-cylindrical shank M.
m isa semi-annular lug or projection extending from the shank M near its end, and adapted to extend into the annular groove N to prevent any longitudinal movement of said shank in the sleeve A without preventing the turning of said sleeve.
The various parts of the abovc-described device are adjusted and secured in place as follows: The shank M is placed within the sleeve A, the semi-annular projection m extending nto the annular groove N. The shank b is placed within the sleeve A, with its flatsurface against the fiat surface of the shank M, its screw-threads engaging with the screw-threads of the sleeve A. Said sleeve is then turned, drawing in the shank b. The operation of the above-described device is as follows: The heads B and C being adjusted to a proper distance apart, the rod D is turned about its pivot d to the position shown in Fig. 4:. The object to be grasped is placed between the end of the head B and the side of the head C, and clamped between said heads by turning the rod D about the pivot d toward the head B. If the part grasped by the wrench is of a conical form, the head C will turn about the screw F until its grasping-surface bears squarely against the sur face of the object grasped. Then it is desired to secure a new hold upon the object grasped by the wrench, the handle A is turned backward about the pivot d, the hold of the wrench being thereby loosened.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, ism
l. rlhe combination of the internally-screwthreaded sleeve A, provided with the annular groove N, the head B, provided with a selnicy lindrical shank having screw-threads adapted to engage with the internal screw-threads of the sleeve A, the semi-cylindrical shank M, provided with a lug adapted to extend into the groove N, the rod D, pivoted to the shank M, and the head C, secured to the rod D at its upper surface at the end, substantially as shown and described.
2. The combination of the internally-screwthreaded sleeve A, provided with the annular groove N, the head B, provided with a semi-cylindrical shank having screw-threads adapted to engage with the internal screwthreads of the sleeve A, the semi-cylindrical shank M, provided with a lug adapted to eX- tend into the groove N, the rod D, pivoted to the shank M and the head C, pivotally secured to the rod D atI its upper surface at the end, and provided with a lug adapted to strike against the rod D to limit the pivotal movement of the head C, substantially as shown and described.
JOHN Il. LANE.
