Patent GB-301280-A (GB)
Title: Process and apparatus for the production of files and file casings
IPC: B23D73/00
Filed: 1928-05-15
Abstract: 301,280. Peiseler, A. May 15, 1928. Milling-machines; milling-cutters; bar feeds.- In a, process for making files, the blank is fed past a helically-threaded milling-cutter, which is arranged obliquely to the line of feed and is rotated in unison with the blank feed so that the teeth are produced by a hobbing action. The file teeth may be out on a continuous steel band, which is subsequently cut into separate file elements. The band a delivered from a supply roll may be first passed through straightening rolls (not shown), and then through a pair of feed rolls 8. 9 which feed the band to a threaded cutter 10 of conical form driven synchronously with the rate of feed. This cutter forms the teeth in one of the narrow sides of the file, the work being supported under the cut by a roller 11. The band is then fed between a pair of cutters 12, 13, which are arranged a.t an angle to the direction of feed according to the angle desired on the file teeth. The line of contact X extends diagonally across the file so that the teeth are continuously generated over the whole surface. By arranging the cutters 12, 13 to operate after the cutter 10, any burrs produced on the broad face of the file by the edge-cutting operation are removed. The cutter 10 may be arranged with an axial plane parallel to the line of feed. After passing the cutters 12, 13 the band passes to shearing cutters, which divide the band into separate file-elements. The band feed is assisted by means of endless chains 21. 22 passing round rollers 16 - - 20. The upper chain is provided with teeth o.', the same pitch as the lile teeth, and is kept in engagement with the file by means of spring-pressed rollers 23, 24. If coarse teeth are to be cut, the narrow face of the blank may be cut by the tool shown in Fig. 3 having teeth whose depth increases in the direction of the feed. For the broad faces a number of pairs of cutters such as 12, 13 may be arranged to operate in succession , each pair of cutters having teeth of greater depth than the preceding pair. When conical cutters are employed the teeth produced have a positive front rake, but if this rake is not required cylindrical cutters may be used. After the cutting of the teeth, the files may be provided with clearing grooves by drawing the band past suitable planing or slotting tools. Instead of operating on continuous bands, the file blanks may be produced separately by forging &c., and then fed past the cutters by mounting the blanks in a jig comprising a steel carrier having openings to receive the blanks, which project beyond the carrier so that both faces may be cut. The openings may be inclined to the length of the jig so that successive blanks mutually overlap. By using jigs with openings of different inclinations, the angle of the file teeth may be varied without disturbing the cutters. The invention is also applicable to the making of case-files, wherein the teeth are cut in plates adapted to form a casing surrounding a core of cheaper material.

Filed: 1916-10-09
Abstract: 125,652. Stone, A. J., and Shuker, W. Oct. 9, 1916. Ordnance design.-Relates to guns in which recoil is eliminated by the rearward discharge of a dummy projectile. According to the invention, the projectile proper 1, the propelling-charge 3, and a light mass 2 in the form of a copper, brass or other softmetal cup are contained within the usual case and loaded as a single cartridge into the front barrel portion 5 of the gear, the rear barrel portion 6 being removed for this purpose. On igniting the charge 3 through a passage 4, the projectile 1 moves forward and the cup 2 rearward, the latter engaging with friction a slightly tapered portion of the barrel 6, which friction, it is stated, annuls recoil by compensating for the small mass of the member 2 in comparison with that of the projectile. The tapered portion of the barrel may lead to a second portion of more gradual taper. The Provisional Specification also de. scribes a cartridge case adapted for rim fire with passages leading to the charge. Reference has been directed by the Comptroller to Specification 125,605.

Title: Controlling the movement of a mechanism by an escapement with adjustable periods
IPC: G04B18/00
Filed: 1943-09-03
Abstract: 573,969. Escapement mechanism; brakes. DERUNGS, E. A., and CHATELAIN, O. Sept. 3, 1943, No. 14442. Convention date, Oct. 21, 1942. [Class 80 (iv)] [Also in Group XXXIV] In escapement mechanism wherein the movements are regulated by a lever fixed to the axle of a balance, the periods of the oscillations of which can be varied by modifying the movement of inertia of the balance by the displacement of masses, the masses are fixed to levers carried by the axle and by means of which the masses can be moved away from or toward the axle. An escape wheel 12 receiving its movement from a pinion 14 is controlled by pallets 13 mounted on a tube 15 supported on a plate 11 by a shoulder, and in a plate 10 by a ball bearing 17. Through the tube passes a rod 18 carrying a pin 19 located in slot 20 in the tube and through a collar 21 connected by rods 22 with the shorter arm of bent levers 23 carrying weights 24. By raising rod 18, e.g. by pressing on a button 30, the weights are brought closer to the axis and'the moment of inertia and the period of oscillation are reduced. Thus, with the mechanism driven by a spring motor with decreasing power, a suitable braking could be applied at starting and reduced as the spring unwinds. The Specification as open to inspection under Sect. 91 describes also an escapement controlled electrically, Fig. 3 (Cancelled), in which pallets 30 are fixed to a toothed balance 37 oscillating between toothed poles 38 of an electromagnet 39 with energizing coil 40 and adjustable magnetic shunt 42. The coil is in series with an adjustable resistance 43 with slider 45. The escape wheel 31 is connected through gearing 32, 33 to a pinion 34 engaged by a rack 35 carrying the slider 45. At starting, the magnetic field is strong and the oscillations of 30 relatively slow, but, as the rack 35 descends under some force 36, the current through coil 40 and the magnetic field are reduced and the oscillations become more rapid. This subject-matter does not appear in the Specification as accepted.
