Title: Gun stock checkering machine
IPC: B27M1/00
Filed: 1958-03-14
Abstract: 880,171. Copy-turning. OLIN MATHIESON CHEMICAL CORPORATION. March 14, 1958 [March 27, 1957], No. 8336/58. Class 83 (3). A checkering machine for gunstocks comprises means for rotating a workpiece W, and synchronized means for traversing a cutter carriage 33 along the work. A main motor M1 rotates a screw 31, for traversing the cutter carriage 33, and a cam-shaft 16. The shaft 16 carries a pair of opposed templates 19 which co-operate with an electric tracer-head 38 on the carriage 33, to control the upper cutting-head so as to limit the extent of the generation of the left-hand threads. A similar pair of templates 21 control the lower head for right-hand threads. The gun-stock W is mounted on a shaft 22 secured to a face-plate 23 by an adjustable eccentric mounting 26. The offset partly compensates for the effect of taper on the stock in the area to be checkered. The carriage 33 is initially set at an angle to the work axis corresponding to the lead angle of the screw 31. Each cutter is rotated by a motor M2 (M3) which is rocked about a pivot by a spring and a solenoid acting in opposition, to move the cutter to and from cutting position. The depth-of-cut is determined by followers 40, Fig. 3, straddling the cutter, which is withdrawn between, or projected beyond, the ends of the followers according to the energization of a solenoid 52 controlled by the associated tracer-head. The cutting action is transferred from one head to the other by switches such as 63, actuated by the carriage at each end of its travel. The work is oscillated by just over 360 degrees for each traverse, so that succeeding cuts are displaced around the stock. The machine is stopped when a pin 59, rotating with the work, strikes a lever 58 to actuate a switch 57, the work then having been rotated through a complete indexing revolution. In a modification, means are provided to support several workpieces one above the other, with a single means controlling the movements of a number of cutters. The cutters may be drills or endmills.

Abstract: 978,328. Presser arrangement in winding machines. COMPAGNIE DE SAINT GOBAIN. March 4, 1963 [March 6, 1962], No. 8469/63. Headings DID and D1J. Roving 16, e.g. of glass fibres, to be wound on to a bobbin 1 is guided thereto by means of a presser assembly comprising a pivotally mounted unit 20 on or from which are supported a guide wheel 25 mounted above the bobbin 1, a thread guide 2, a roller 3 which presses against the wound material on the bobbin 1, a counterweight 22 and lever 21, the whole assembly being arranged so that its centre of gravity coincides with a shaft 5 on which it is pivotally mounted. The assembly is therefore in stable equilibrium whatever its position, and the pressure between the roller 3 and the bobbin, and the tension of the roving as it is wound onto the bobbin are substantially constant throughout the growth of the wound package and are determined by the tension K in the roving leaving the tensioning device 18. The guide roller 25 is suspended from a frame 23 and is adapted to oscillate with the traversing motion of the thread guide. The thread guide is mounted on a carriage for reciprocal traversing movement under the action of a grooved cam mounted on the shaft 5 (Fig. 4 not shown), and may itself comprise a grooved roller (Fig. 7 not shown). A bent wire forms a fork or eye 27 through which the roving passes to the thread guide and is mounted on the thread guide carriage. A common motor drives the bobbin and traverse cam.
