Title: Improvements relating to bobbin-winding machines
IPC: B65H54/32
Filed: 1930-02-10
Abstract: 346,091. Yarn-winding machines. RUKA GES. FœR PATENTVERWERTUNG, 10, Neum³hlequai, Zurich, Switzerland. Feb. 10, 1930, No. 4520. Convention date, Feb. 8, 1929. [Class 120 (ii).] In a bobbin - winding machine wherein the throw of the thread guide is controlled by a swashplate and is gradually reduced to produce bobbins with conical ends, the means which effects reduction of the traverse simultaneously effects a reduction in the speed of the winding spindle, thus allowing the thread to be wound at a constant rate. The swashplate 11, Figs. 1 and 2, which is driven from the shaft 7 by means of friction wheels 6, 3 and pinions 8, 9 causes the sliding carriage 13 to reciprocate on the bar 53 and tube 16, and so traverse the thread guide 14 fixed to the rod 15 which slides inside the tube 16 and is connected to the carriage 13 by means of a pin 54 passing through a slot in the tube. A crank 33, Fig. 3, mounted on the main shaft 10 actuates a ratchet and pawl 29, 48 supported on a lever 46 pivoted at 47. The ratchet 29, through reduction gearing 28, 27, 26, 50 slowly rotates the pulley 24 round which a wire 23 is wound, the other end being attached to the stirrup 22. This causes the traverse mechanism i.e. bar 53, tube 16 and carriage 13 to rotate about the axis of the tube, whereby the contacting pins on the carriage 13 are moved across the swashplate towards its centre and so decrease the traverse. At the same time, the fork 40 attached to the end of the tube 16 slides the driving disc 6 across the face of the friction disc 3 and so increases the spindle speed, the spindle being driven through pinions 8, 36. When the winding of the bobbin is completed, the hand shaft 34 is pulled ; this moves the worm wheel 50 clear of the worm 26 and so disengages the pulley 24 from the ratchet mechanism, whereupon torsional springs 35 rotate the traverse mechanism into its original position.

Title: Means for measuring the frequency of electric or mechanical impulses
Inventor: DEACON LIONEL OAKLEY
IPC: G01R23/10
Filed: 1949-02-21
Abstract: 688,202. Speedometers. CHAMBERLAIN & HOOKHAM, Ltd., and DEACON, L. O. Feb. 16, 1950 [Feb. 21, 1949], No. 4642/49. Class 106 (iii). [Also in Group XXXVI] Apparatus for measuring the frequency of electrical or mechanical impulses comprises an indicating pointer carried by a spindle intermittently rotated against a return spring by two alternately operative deflecting pawl-andratchet mechanisms responsive to a train of incoming impulses and having a third retaining pawl-and-ratchet mechanism operative to hold the spindle against rotation in the opposite direction; together with a cyclic time control mechanism which renders the deflection ratchet mechanism operative and inoperative over successive alternate time intervals, and renders the retaining ratchet mechanism inoperative at predetermined time intervals, allowing the pointer to reset. An instrument for measuring the frequency of electric or other impulses comprises spindle a, loaded by return spring m, carrying pointer b and ratchet disc c<SP>2</SP> retained by detent pawl j disengagable by electromagnet k. Other ratchet discs c, c<SP>1</SP> freely mounted on the spindle and loaded by return springs i are rotatable by pawls f operated by electromagnets g and disengagable by electromagnets h. Each disc c, c<SP>1</SP> carries a projection d which may engage a corresponding radial arm e on the spindle, which is thereby rotatable against its return spring m. The various electromagnets are sequentially operated and released by switching cams 2, 3, 4 carried by spindle y rotated by ratchet disc 5 electromagnetically stepped by clock x. The instrument is initially in the position shown, and a train of impulses across the terminals n energizes electromagnet g through switch contacts o, p to step disc c<SP>1</SP> and rotate spindle y and pointer b in proportion to the number of incoming pulses while the pawl of disc c is held inoperative by electromagnet h energized through contacts s, t. After a predetermined time, cam 3 opens contacts s, t to release the pawl of disc c, and cam 4 closes contacts v, w to energize electromagnet k and release pawl from disc c<SP>2</SP>, but the spindle is prevented from returning until cam 3 closes contacts s, u to release the pawl of disc c<SP>1</SP>, when the return movement is limited by engagement of arm e with projection d on ratchet disc c. Immediately before, or simultaneously with, the closure of contacts s, u, cam 2 opens contacts o, p and closes contacts o, q, so that the impulses now step disc c during the return movement of the spindle and pointer, and while disc C<SP>1</SP> is inoperative. Thus the pointer is continually and cyclically deflected and reset to indicate the incoming pulse frequency, and the ratchet discs c, c<SP>1</SP> are alternately operative and inoperative so that during pointer resetting, one or other disc is actuated by the incoming impulses, none of which is lost.
