| 799,091. Making files; shearing. TREBITSCH, G. Sept. 3, 1956 [Sept. 3, 1955], No. 26849/56. Classes 83 (2) and 83 (4). A file is made from a sheet metal blank by securing the blank in a frame advancing the frame step-by-step past a stamping tool and operating the tool after each step to cut through and deform the blank, so producing a series of cutting edges spaced along the file. The file may be as described in Specification 772,738. The frame 21 is frictionally held to bed-plates 11 by straps 19. The tool consists of a moving and fixed part 4, 5, respectively, guided relative to each other by pins 2 and carrying one or more chisels 7, 8 mounted obliquely. The chisels slit and bend slats in the blank which is secured by straps 23, 24 in the frame 21. The strap 24 is spring-loaded and adjustable and may be moved by a lever 28 to insert the blank. The frame is stepped by engagement of a pin on the moving part 4 with the sloping face of a spring-loaded member 35. A pawl carried by the member 35 engages a rack 34 on the frame 21 which is stepped when the member 35 is reciprocated. A counter 45 is actuated when the frame 21 reaches the end of its travel. | ||||||

| 695,830. Making files, milling and planing cutters, graters, &c. BOOTH, C. H., and HARDWICK, H. B. April 29, 1952 [May 3, 1951], No. 10448/51. Classes 83 (ii) and 83 (iii). [Also in Group XXIII] A cutting element, similar to those described in the parent Specification and Specifications 666,573 and 666,622, for use as a file, rasp or cutting band, disc or drum, is made by upsetting parallel rows of spaced tongues 7 from a flexible sheet or strip of hardenable steel or iron alloy, removing, e.g. by grinding, the upset free ends of the tongues parallel to the surface of the blank to form sharp edges 11, Fig. 5, bending the blank in one direction along lines within the length of the tongues and reversely bending it along lines between the rows of tongues so that the blank is corrugated with the tongues protruding at a suitable cutting clearance angle, and finally hardening the cutting edges. The ridges of the corrugations provide non-cutting surfaces which rub on the work and prevent the edges from digging in, as described in Specification 695,859. D-shaped holes 9 are first punched out ahead of the tongues and the tongues are upset to a greater extent than finally necessary, in order to free the edges of the slits 10, and then pressed back to the desired degree of upset; this upset is generally a little more than the thickness of the material but may be varied to give different included angles c, Fig. 5, between the sides forming the cutting edge. By adjusting the relative positions of the bending dies 12, 13, Fig. 9, so that the front bending line is moved further back from the cutting edge, the extent to which the edge protrudes may be increased, and by varying the sharpness of the bends, the rake and clearance angles a, b, Fig. 11, may be varied. The strip may be surface-hardened by cyanide treatment and quenching or by gaseous diffusion of tungsten, cobalt or molybdenum and chromium, or may be hardened throughout and the ridges of the corrugations tempered to provide flexibility. Burrs on the sharpened edges are removed by sand-blasting. The strip may be bent to convex form to provide a half-round file, the corrugations being formed before or after bending to convex form. Cutting edges may be formed on both sides of the strip, preferably at opposite sides of rectangular holes, with the edges at the tops of the reverse bends. Specification 695,821 also is referred to. | ||||||

| 683,355. File-cutting machines. MUNDORF, H. Jan. 23, 1951 [Feb. 21, 1949], No. 1759/51. Class 83 (iv). In a file-cutting machine of the type where there is relative longitudinal movement between the cutting tools and file blanks 5, 6, and oppositely - acting cutting - tools 8, 9 act simultaneously on opposite file surfaces, the cutting- tools are moved along the surfaces of the file blanks which are clamped in a fixed position. Two blanks are clamped on a fixed saddle and a movable table 7 carries oppositely acting first cut and second cut tools 9, 8, respectively, smoothing files 12, 13, for trimming the first cut teeth, and edgecutting tools 17, 18. Guide surfaces 19, 20 conform to the profile of the blanks and ensure a uniform depth of cut. The tools are automatically brought into operation and disconnected successively by couplings 14, 15, which connect the tools 9, 8, respectively, to driving shafts a, b, and by a coupling connecting tools 17, 18 to driving-shaft 16, the couplings being controlled by rods 21 &c. coacting with stops on the table 7. | ||||||

| 673,026. Electroplating. SCHROTH, F. Dec. 20, 1949 [March 31, 1949], No. 32609/49. Drawings to Specification. Class 41. [Also in - Group XXII] In a method of making sharp-edged tools such as files, rasps, milling cutters, drills, reamers, &c. the formed tools are sand-blasted on the cutting surfaces and coated with a layer of hard metal such as chromium. A file having a tooth form made in the normal manner and which has been hardened and quenched in oil is sandblasted directly against the cutting edges and coated with chromium. Glass or quartz sand of 120 mesh may be used and has the effect of sharpening the cutting edges when directed thereagainst. Cutting tools of unhardened or non-hardenable metals may be made by the method. | ||||||

| 663,343. File-cutting machines. WALTERS, B. Aug. 4, 1950 [Oct, 19, 1949], No. 26804/49. Class 83 (iv). In a file-cutting machine wherein a hammer 8 is carried in inclined guides in a vertically-sliding frame 5, 5A, the weight of which is applied through a metal foot 11 to hold the blank during cutting, a lever 14, 14A is pivoted to the machine base 4 at 15, and to the sliding frame at 18 and carries an adjustable load 19 for adjusting the pressure exerted by the foot. Holes 20 in the lever provide for increasing the pressure on the foot and holes 20A for reducing the pressure. | ||||||

| 649,002. File-cutting machines. BOOTH, C. H., and HARDWICK, H. B. April 13, 1948, Nos. 10244/48 and 1539/49. [Class 83 (iv)] [Also in Group XXIII] A machine for producing teeth on files, saws, &c. comprises a chisel 27 which is reciprocated to strike a tool-blank 22, one or more bearing- members to support the blank during striking, a carrier 32 which is rotated about the blank and which carries hammer members 36 repeatedly to drive the chisel and the bearing member or members simultaneously into engagement with the blank, and means for feeding the blank between strikes to form a succession of gullets and sharp-edged ridges. In the machine described, the bearing-member is a second chisel 27. The chisels are adjustable in holders 25 by wedge means, the holders being mounted by resilient rubber sleeves 31 in sleeves 29 resting in sockets 15. The chisels are reciprocated by the rollers 36 in the fly-wheel 32 which is rotated by pulley means 34. The blank 22 is fed continuously by means embodying a cushioning device. The rollers 36 are inclined and are moved axially by means 46 to adjust the stroke. The natural frequency of vibration of the resilient mountings is substantially equal to the normal frequency of reciprocation of the chisels. Three chisels or, as stated in the first Provisional Specification, four chisels, may be provided. | ||||||

| 565,428. File cutting machines. WALTERS, B. July 9, 1943, Nos. 11139/43 and 672/44. [Class 83 (iv)] In a file-cutting machine of the type in which the tooth-cutting chisel 19 is reciprocated in guides 20 in a vertically movable slide 16, the weight of which is carried by a foot 23 resting on the blank 24, a mechanical device is arranged between the foot 23 and slide 16 to enable the height of this to be adjusted. The adjusting device may comprise a non-rotary cam 33 of a slide 28, which is axially movable in the slide 16 and to which the foot-carrying rod 25 is adjustably secured by screws 34, 37, and a cam 35, which is arranged on the rod 25, between the slide 16 and the cam 33, and can be rotatably adjusted by a handle. In a modification, the slide 28, Fig. 6, is automatically adjusted, as the blank carrier 12 is fed, by a cam 54 thereon, roller 51, slide 46 and lever 43. The slide 46 and, if desired, the slide 28 may be supported by springs 55. The upward movement of the slide 28 may be limited by a stop 56. | ||||||
