MONKEY-WRENCH.
' SPECIFICATION forming part of Letters Patent No. 753,837, dated March 8, 1904.
Application filed September 21, 1903. Serial No. 174,052. (No model.)
'in the appended claim.
In the drawing forming part of this specification a wrench embodying my invention is.
shown in side elevation.
The handle-bar of the wrench is shown at 1, and a't 2 is represented the immovable head of the handle-bar. The movable jaw 3 is slotted to slide loosely on the handle-bar 1 and is recessed above the handle-bar to receive a spiral spring 5. Ahooked extension 4 of the slidable jaw forms a rounded bearing for the cross-bar 7 of a clamp-link 6. The clamp-link is shaped to t over the handle-bar somewhat loosely, and its rounded cross-bar 7 is adapted to slide sidewise to place in the movable jaw. The slot through the clamp-link is somewhat longer thanthe width of the handle-bar, and the link is made to clamp the handle-bar by swinging it obliquely across the bar, as
`shown in solid lines in the drawing. The
clamp may be effected by hand; but it is preferable to use spring 5, which is attached at oneend to jaw 3 and at the other end to the clamp-link.
The parts are assembled by sliding the clamp-link into position in a slidable jaw, securing the spring 5 to the link and to the jaw, and then sliding the jaw and the link onto the handle-bar 1. The movable jaw may be slid toward the stationary j aw Without obstruction. As soon as the slidable jaw is at rest the spring pulls the clamp-link obliquely across the handle-bar, and stress tending to separate the jaws increases the pinch of the olamp-link onto the handle-bar and holds the movable jaw rmly in place. When it is desired to shift the movable jaw away from the station ary jaw, the clamp-link is swung by linger-pressure into the position shown by dotted lines in the drawing.
I claim- In a monkey-wrench, the combination of handle-'bar having a stationary jaw-head, a
slidable jaw on the handle-bar havingahooked extension and a clamp-link having a roundedcross-bar adapted to slide sidewise 'into the bearing 'formed by the hookedA extension of the slidable jaw.
In testimony whereof I sign my name in the presence of two subscribing witnesses.
LUTHER C. BARCUS.
