Be it known that I, CHRISTCPIIERRICHARDSCN, of Newark, New Jersey, have invented a new and improved mode al' making metallic Saw-Frames; and I do hereby declare that the following is a full, clear, and exact description ofthe construction of the same, reference being had to the annexed drawings, making a part of this specification, in Which-,
Figure 3 is a side view of the frane.
Figures '2 and l, a side View and plan of a handle; and
Figure 4 an end view ofthe clamp for holding the blade;
The object of my invention is to provide a'better means of holding the sawlbladein theL frame than can be *furnished by any pin, rivet, or stretching screw. To hold the blade, an'opening ismadenleendof the frame' of about the thickness of the saw-blade, and a screw passed through the frame and openiing from side to` side, affording the means to clamp the blade tightly after it has been properly stretched by the'stretclling-screw, which passes through the frame at the side of the clamping-"screw, in the same direction as the saw.
The same letters refer tothe same parts in all the figures.
a is a handle of metal, attached to a metallic sawframe, shown in part in figs. 1 and 2. T his handle is made entirely of metal, and is hollow at b, to make it`lighter. The part embraced by the hand Vis covered with leather, woollen, Sie., to make it feel warm in cold weather. c is a handle, shown in iig. 3, made entirely-ol` metal, except the part d, embraced by the hand, which is of Wood, secured between the horns e and f of the handle. gis the opening in saw-frame, extending to t', in which the saw-blade h can be inserted andiirml'y clamped by the screw n, after being vproperly stretched by the stretching-serew o.
I do not claim the invention of these screws, or the use of them separately, as they may have been use before, but I believe they have never been used together.
What I claim, therefore, and `desire to secure by Letters Patent, is
The improved method of holding saws in metallic saw-frames, substantially as shown and described..l 1
