NUT-WRENCH.
SPECIFICATION forming part o f Letters Patent No. 602,054, dated April 12, 189 8.
" Application filed December 11,1897. seria No. 661,578. oro modem' To all whom it mctgfconcern:
Be it known that-I, HENRY L. BUTLER, a citizen of the United States,vresiding at Emerson, in the county of Dixon and State of Nebraska, have invented certain new andy useful Improvements in lNut-VVrenches; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part 'of this specification.
Thisinvention relates-to nut-wrenches, and is directed more particularly to that class of such devices which are adapted for use in the manipulation of nuts employed to secure together the members of a vehicle-wheel, although certain of the features of the invention are susceptible of embodiment in other types of wrenches adapted for other uses.
The nature of the invention will be readily understood from a reading of the following detailed description when taken inconnection with the accompanying drawings, in which Figure l is a View in elevation of my improved wrench, and Fig. 2 is a broken sectional view.
Referring to the said drawings by letter, A denotes a bar, at the upper end of' which is a bevel gear-wheel b, said wheel being mounted on the shaft portion c of an operating crankhandle c. This wheel b meshes with aseoond bevel gear-Wheel d, mounted on a spindle e, which is-journaled in a bracket f, said bracket being secured to the bar A by means of a threaded pin f' and a nut f2. The upper portion of the spindle is squared for engagement with a corresponding opening in the gear-wheel cl, and beyond the squared por- 'tion the spindle is reduced in diameter and is threaded to receive a nut e, by which means said wheel is made rigid with the spinvThe spindle has near its other end a flange or collar e2, which abuts against the under side of the bracket and coperates with the wheel d to prevent endwise movement of the spindle. Beyond the flange or collar the spindle partakes of the form of a Wrenchhead es, being socketed to conform to the size ing a socket conformable to a different size or shape of nut may be inserted. It is also within the sco pe of, my invention to construct the lower end of the spindle Vto receive removably separately-made wrench-heads having sockets of different lsizes or shapes, and in such a construction it'is obvious that the spindle need not necessarily be made removable.
Adjacent to the Wrench-head is provided the Xedvjaw g of a clamp G, which clamp is employed in practice for firmly grasping the wheel or other device during the wrenching operation. Thisv jaw is bolted or otherwise secured to the bar A, and its engaging end g is bifurcated and curved to obtain in pracl tice the proper bearing. The movable jaw g2 of the clamp is pivotally secured on the bar A by meansof a bolt h and nut h, and g5 is a handle by which said jaw may be moved to or from the fixed jaw. For the purpose of adjustment the opening in the bar A for the bolt h is of slot form, and said bolt is shouldered to provide a stop for the nut h', whereby binding of the movable jaw is prevented. That portion of the bolt which is within the slot is squared to prevent its rotation and the consequent accidental loosening of theqnut.
In the application of the device to the securing-nuts on a vehicle-wheel the Xed jaw is brought against the inner side of the wheelrim and the nut-socket is fittedA over the nut. The jaw g2 is then brought against the outer side of the rim by moving the handle g3 toward the bar, and the outer end of said movable jaw is caused to abut against the head of the wheel-bolt. The operating-handle c is then turned and the spindle rotated through the interposed gearing, with the result that the nut is readily and rapidly loosened 'and removed. Substantially this operation is effected in the tightening of the nuts, the only difference beingin the reverse rotation of the operating-handle.
The advantages resulting in the use of my improved wrench will be obvious to those skilled in the art. Not only is the saving of IOO labor enected, but the operations are attended with neatness and despatch. Moreover, the
adjustable feature 0f the clamp and the provision of the changeable wrench-heads greatly 2. In a nut-wrench, the combination with a` clamp comprised of a fixed and a movable jaw, said fixed jaw having a bifurcation, of a spindle, a wrench-head carried by the spindle and located at the bifurcation, a bevel gearwheel on said spindle, a second bevel gearwheel meshing with the aforesaid'gear-wheel, and a crank-handle connected with the second wheel to operate it, substantially as described. Y
3. In' a nut-Wrench, the combination of a slotted bar, a movable clamp-jaw pivoted on a bolt adjustable in the bar-slot,a fixed clampjaw secured to said bar adjacent to the movable jaw, and having its outer end bifurcated and curved as described, a bracket on said bar, a spindle journaled in said bracket having at its lower end a wrench-head, and having at its upper end a squaredportion and a reduced screw-threaded portion, a bevel gearwheel on the squared portion, a nut on the reduced portion, and a secondbevel gearwheel meshing with the aforesaid gear-Wheel and mounted on an operating crank-shaft journaled in the upper end of said bar, substantially as described.
In testimony whereof I aix my signature in presence of two witnesses.
HENRY L. BUTLER.
