rilhis invention relates to an improvement in such hand-saw frames, which consist of two arms, which are connected by means of a connecting-piece and Which on one side of the connecting-piece are provided with a sivingably arranged lever intended tor the tensioning of the saw-blade.
lln the accompanying drawing' is shown an embodiment ot' the invention, Figi'. i shoi s 0 from the side a hand-saw trame provided with the improvements accordingn to the invention. Fig. 2 is a section on the line 2 2 in Fig. l and Fig. 3 is a section on the line 3 3 in Fig. l shown in larger scale. Figure 5 t is a transverse sectional view taken on lines 4 4 of Figure 1.
ln the drawing', l indicates the arms provided With the saw-claws 3, Which arms are connected by means of the connecting-piece o 5. riceording1 to the invention the conne-et ing-piece 5 is further provided with a delongitudinal grooves l (Fig. 3) for holding additional loose saw-blades 2. yl`he connecting-piece 5 is tui-ther provided With a depression 6, Fig. 3, in which the lever 'for the tensioning ot the saw blade is provided with oppositely disposed eyes 8 at its upper end to receive tensioning Wires 9 Which are connected at their opposite ends to the arms 4l o as illustrated in Figures l and 4, the lever Z being swung about the Wires to twist them, and thereafter catchingv its :tree end in the depression and being held there it thereby prevents the saw-blades in the groove from falling out of them.
rllhe arrangementmay oi course be modified in several respects Within the scope of the invention, and especially the number oi the grooves l may be varied Without deviat ingr i'rom the principle oit the invention.
llaring` now described yonr invention, what we claim as new and desire to secure by Letters Patent is:
fin improvement in hand-saw frames, consisting of two arms connected by means ot a connecting-piece, which on one side of the connecting-piece hold the saw-claws and on the other side oi' the connecting-piece are provided with a svvingable lever for the tentritatiing,I ot' the saWblade, said connecting piece being provided with a plurality of longitudinal grooves for holding additional loose sa-W- lades, said connecting-piece being provided With a depression, in which the free end o1a the tensioning' lever is held, said Yfree end thereby preventing the saw-blades in said grooves from falling out of them.
y ln witness whereof, we have hereunto signed our names.
