Abstract
432,026. Cutting files. STUBS, Ltd., P., Warrington, and WINTERHOFF, W., 33, Grappenhall Road, Stockton Heath, Warring- ton. Jan. 13, 1934, No. 1254. [Classes 83 (ii) and 83 (iii)] Planing and shaping.-A machine for cutting files comprises a frame 10 having guides 12 for a reciprocating carriage 13 from which a tool holder 21 is flexibly supported so that by manual means such as a pedal the tool may be withdrawn from the work mounted on the carrier 24 at any part of the stroke. In a modification, the positions of the tool and work may be interchanged. The carriage 13 is reciprocated by an adjustable power-driven crank disc 17 and connecting rod 16 and the carriage is fitted with lugs 22 supporting by links 19 a frame 20 secured to the tool holder which is angularly adjustable around a bolt 34. The frame 20 carries a threaded rod 26 slidable through a lever 28 which is normally urged upwards by a spring 31. The end of the lever is carried on a spring 33 which is compressed to engage the tool with the work by means of a pedal acting on a chain 33b. The tool 23 traverses the whole surface of the blank, but on the return stroke the pressure on the pedal is released so that the spring 33 lifts the tool clear of the file point. In another modification the carriage may be actuated by a hand lever through a toothed sector and rack. Specification 13268/03, [Class 61], is referred to.
