Title: Process for producing parts having a head and a shaft, particularly screws, and apparatus for executing the said process
IPC: B21K1/44
Filed: 1951-04-12
Abstract: 691,643. Making bolts, screws, &c. HATEBUR, F. B. April 12, 1951 [April 14, 1950], No. 8559/51. Class 83 (iv). Forging; extruding.-In a method of making bolts &c. having a head and shank a blank is sheared from a metal bar and formed with a conical end by partial extrusion in a die having a conical extrusion orifice and the shank is then extruded in a second die having a similar orifice. A blank 2, Fig. 3, of the same volume as the required bolt is sheared from a hexagonal bar and fed into a profiled chamber of a die 3 having a conical extrusion orifice and is compressed, preferably while cold, by a plunger 20 to form a conical end 4 and a partially extruded tip 5. The blank is then ejected by a pin 6 and moved by tongs 8 to an extrusion die 9, Fig. 5, having a conical orifice 10 for the extrusion of a shank 11 by a plunger 22. The blank is then ejected by a pin 23 and transferred to a third die 13, Fig. 7, by tongs 12. In this die the bolt head 15 is formed by a piston 14 having a cavity of the required shape and an ejector pin 24 locked in position to enclose the end of the cavity during the forming operation. The die 13 may have an orifice 16 for forming a reduced part of the shank. The blank is ejected by a pin 25 and is finally screw threaded. The pressure chamber of the first forming die 3 consists of two parts 40a, 40b, Fig. 10, separated in the plane through the axis of the cavity. The parts 40a, 40b are mounted on a reciprocating slide 41 which alternately moves the chamber transversely in front of a bar feeding position (as in Fig. 10) and the extrusion orifice in a fixed body 39. The bar is fed into the chamber from a feed guide (not shown) and sheared off between a cutting face of the part 40b and a face on the feedguide as the slide 41 returns to the position for extrusion of the blank. The part 40a is rigidly fixed to the slide 41 but the part 40b is slidable to free the blank during ejection and is locked in position during forming by a reciprocable pin 46 and a link 44. The dies 9, 13 may comprise two parts separated in a plane transversely of the bore, one part containing the pressure chamber and the other containing the conical extrusion orifice and the passage for the extruded shank. The pressure chambers in the die may be tapered and of the same general shape but slightly larger in cross-section than the blank. The corners of the profiled shape may be sharper than that of the blank in order to reduce the area of contact for ease of ejection. In a modification the blank is sheared by a separate cutter which transfers the blank to the extrusion orifice. A spring finger grips the blank on the cutter and a gauging stop, against which the bar is fed, moves with the cutter and then moves forward to feed the blank into the die.

Title: Method of measuring the thicknesses of magnetic metal plates
Inventor: TAKAHASHI MASAKAZU
Filed: 1964-03-02
Abstract: 1,061,895. Measuring thickness of ferromagnetic plates, electrically. YAWATA IRON & STEEL CO. Ltd. March 2, 1964, No.8684/64. Heading G1N. In a method of measuring the thickness of a ferromagnetic plate 4 (Fig. 1) a yoke 1 is brought into proximity with the plate the yoke having a cross-sectional area whereby it is not saturated when current in a coil 2 thereon produces a flux which saturates the metal plate. The coil is excited successively by two fixed value saturating currents (e.g. 3 amps. and 2À7 amps.), the magnetic potential difference between the two legs of the yoke across the plate at each current value is determined by a coil or coils 3, wound on a non magnetic former, and in which a voltage is induced, representative of magnetic potential difference. The difference in magnitude of the two magnetic potential differences is taken as a measure of the plate thickness, being compared with characteristic curves representing plates of known thicknesses such as in Figs. 2 to 4 (not shown).

Title: Improvements in chain conveyors
IPC: B65G23/00
Filed: 1946-03-20
Abstract: 621,500. Endless chain conveyers. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. March 20, 1946, No. 8709. [Class 78 (i)] In an endless chain conveyer in which a series of article-supporting pockets are mounted on the chain, means are provided for periodically interrupting or varying the rate of linear movement of a portion of the chain in timed relationship with the driving means without disturbing the operation of the driving means or deflecting the pitch line of the chain from its normal path, by alternately reducing and increasing the length of the chain within the limits allowed by the play in the links. In the embodiment shown, a conveyer for use with a sweet wrapping machine is driven at each end by a sprocket and worm drive, the worms being carried on the common driving shaft 18, the worm at one end, not shown, being rigidly secured to the shaft, and the worm 16 at the other end being axially slidable on the shaft. Secured to the shaft adjacent the worm 16 is a cam 31 having an annular cam groove 29 in which runs a roller 28 at the end of an arm 26, the motion of this arm being transmitted by a link 25 to a similar arm 23 and roller 22, which engage an annular groove 21 at one end of the worm 16, imparting reciprocating motion to the worm. When moving to the right as viewed in Fig. 1, the combined linear and rotary motions of the worm 16 are such as to cause the sprocket 15 fo remain stationary whilst a sweet is pushed from its pocket to the wrapping machine, the chain being momentarily shortened by the taking up of clearances in the joints between individual links. Movement of the worm to the left produces a compensating acceleration of the chain to bring the next succeeding pocket into the operative position. Alternatively, the motion of the chain may be interrupted by providing an interrupting member to engage the chain intermittently at a position adjacent the transfer station, or the chain sprocket adjacent the transfer station may be bodily reciprocated. Specification 360,032, [Group XVII], is referred to.

Abstract: 380,824. Moulding artificial resin by hopper-and-plunger machines. KOPP, P., 3, Stubenrauchstrasse, Friedenau, Berlin. March 24, 1931, No. 9055. Convention date, Sept. 9, 1930. [Class 87 (ii).] Artificial resin is moulded in long lengths or as separate articles with intercalated separating plates, by forcing it out of the open end of a mould against the friction of the walls, the mould or piston or both being heated so that the temperature at the outlet end is higher than that at the inlet. Fig. 2 shows one construction in which successive charges of material introduced at the upper end of the mould A are forced down by the piston B and compressed by the reduced lower end before delivery. Fig. 1 shows a modified construction in which clamping members C retard the downward passage of the partly-delivered block to assist in maintaining the desired delivery pressure in the mould. These members may be arranged to grip the material only towards the end of each pressure stroke, being retracted during the earlier portion of the stroke. Fig. 7 shows metal plates D interposed between successive charges of material. The mould may be of any desired profile in cross-section and reinforcements may be inserted in the moulded product during the moulding process.
