IMPROVEMENT IN JlG-SAWS.
Specification forming part of Letters ,PatentNo. 115,101, dated March21, 1876; application filed February 21, 1876.
a ajig-saw.
Figure 1 is a top view of. my improved jigsaw, and Fig. 2 is a sectional elevation.
Similar letters of reference indicate corresponding parts.
'A is the bench or table; B, G, and D, the stationary frame, in which the saw-gate E works by the guides F G, .the gate being pressed down by the foot-treadle H, and raised by the springs I, J and K, spring I being attached to the under side of the stationary frame 0, and connected to the-treadle by the link K, spring J being attached by both ends to beam B, and spring K being attached at its upper end to beam B, and at the lower end to the short arm L of the foottreadle. The saw M is connected to the arms of the saw-gate by the turning studs N O, for shifting'it to any direction, and stud O has thestraining-nut P screwed on it. Q is the presser-foot for keeping the work in position. R is the miter-box gage for sawing miters, the same being a board with right-angled sides S, and a flange, T, to gage it to the table, so that the base of the triangle runs parallel with the saw, and said board and sides S terminate short of the intersecting point of the sides to allow the work to project sufliciently to be sawed to the required bevel.
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- The springs I, J, and K, combined and arranged with the foot-treadle H and the sawgate E, substantially as specified.
PETER HUGHES.
