Title: Improvements in saws for cutting metals
IPC: B23Q11/02
Filed: 1919-05-12
Abstract: 149,421. Herbert, Sir A., and Vernon, P. V. May 12, 1919. Sawing.-A device for removing chips from metal-cutting saws comprises one or more elements adapted to enter the spaces between the saw teeth and to traverse the cutting-faces of the teeth. As shown in Fig. 3, projections 2 form a curved comb on a plate 6 hinged to a collar 4, loosely mounted on the shaft of the rotary saw A. A spring-actuated plunger 9 pushes the plate 6 so that the projections 2 enter the spaces between the saw teeth and clear them of chips. The plate 6 then turns with the saw, putting strain upon a spring 8 which surrounds a rod 7 connected at one end to the collar 4 and passing through a guide 14. On coming into contact with a cam 11, the plate 6 is turned on the hinge 5, the projections 2 being withdrawn, and the plate is returned under the pull of the spring 8 to contact with the plunger 9 and repeat the cycle of operations. In the apparatus shown in Fig. 7, the saw teeth are cleared by projections 17 on a disk 16 at an angle, preferably of 45 to the plane of the saw. The spindle 18 of the disc is driven by spiral gearing from the main driving-shaft 24. Fig. 9 shows a disc 30 with teeth preferably undercut, which mesh with and are driven by the teeth of the saw A. The axle 32 of the disc is carried by a spring-controlled plunger 34. A guard 40 is pressed resiliently on to the disc to act as a, brake. The guard is provided with a lip 43 to deflect the chips away as they are removed from the saw teeth. The disk 30 may have teeth on its face instead of on its edge. A clearing-device may comprise a single finger 46, Fig. 10, attached to a spindle 47 which moves longitudinally in a slotted guide as the finger is rotated by engagement with one of the saw teeth. The longitudinal motion eventually releases the finger from the tooth. The finger then slides along the side of the tooth and is drawn into the next tooth space by a spring. As shown in Fig. 15, the saw teeth are cleared by a peg 60 carried on an arm 61 turning about a pillar 62 against the thrust of a spring 66. A further form of apparatus is described in which the teeth-clearing element takes the form of a lantern pinion, which meshes with the saw teeth. The invention is applicable, also to band and other types of saw.
