Abstract

398,266. Reciprocating-saw machines. SYKES, W. A., Oatlands Mount, Holly Lane, Marston Green, Warwickshire. March 18, 1932, No. 8053. [Class 145 (ii).] A reciprocating-saw machine comprises a tubular frame 1 formed with a depending arm 2, and a work table 4 supported by legs 5. The upper end of the saw blade 7 is attached to a rod 9 reciprocating in a bearing 10 on the arm 2 ; the rod carries a crosshead 11 connected by springs 12 to the frame 1. The lower end of the saw blade is attached to a rod 17 reciprocating in a bearing 18 formed on a member 19 secured to the legs 5 ; the lower end of the rod 17 is formed as a stirrup 20 which is guided by rods 22, springs 23 being interposed between the stirrup and the base. The cutting stroke is effected by depressing the stirrup, the return stroke by the springs 12, 23. In a modification the rod 17 is connected by a link 32. Fig. 6, to a treadle 31 pivoted to the frame 1. A member 25 is telescopically mounted in the arm 2 and carries at its lower end a roller 28 which holds the work down on the table. A guide roller 34 for the blade 7 is carried by a bracket 33 secured below the work table, Fig. 7.
