Title: Improvements in paper feeding and cutting apparatus
IPC: B65B41/18
Filed: 1935-02-11
Abstract: 455,038. Automatic control systems. CLARK, R. S., 1412, Long Road, Kalamazoo, Michigan, U.S.A. Feb. 11, 1935, No. 4384. [Class 38 (iv)] Registration.-A paper feeding and cutting machine comprises means to change the ratio between feeding speed and cutter speed, and to restore it to normal, upon a single engagement of a clutch effected under the control of spots printed on the web for the purpose of maintaining registration between the cuts and designs on the web. The speed ratio is changed by means of a screwed shaft 33 which operates levers 29 to move expanding pulleys interposed between the main or cutter shaft 16 and the feeding rolls 12. The shaft 33 is actuated as required by a disc 35 thereon and a clutch member 36 which :is oscillated with a constant but adjustable stroke by connections to a crank 41 on the cutter shaft 16. Indicating means may be provided on the shaft 33. The member 36 is carried by a yoke 46 and spring 47 from the core of a solenoid 37 which is adapted to be energized under the control of a photo-electric cell 5 in conjunction with spots 4 on the web. Each energization occurs at an instant when the clutch member 36 is at one end or other of its stroke and is maintained throughout a complete cycle thus effecting an increase, or decrease, in the feeding speed followed by an equal decrease, or increase, therein and causing an advance or retraction of the web with reference to the cutting means. To time theseenergizations a drum 51 carrying contact segments B, E, G is driven at one half the speed of the cutter shaft to effect a correction at every second cut, i.e. at a speed appropriate to the frequency of correction desired. The segment B in association with a set of three brushes A<1> passes on an electrical impulse derived from the photo-electric cell 5 and amplifier 56 to a relay 62 or 74 when faulty registration is occurring, the segment G in association with brushes G<1> establishes and holds closed a maintaining circuit for these relays throughout the aforesaid cycle and the segment E in association with a set of brushes D<1> determines the supply of current for the appropriate periods to the solenoid 35. To prevent both relays 62, 74 closing together a contact 78 operated by the relay 74 opens the circuit of the relay 62.

Title: Automatic lathes
IPC: B23Q35/121
Filed: 1951-02-23
Abstract: 696,777. Automatic speed control systems. MONARCH MACHINE TOOL CO. Feb. 23, 1951 [March 8,1950], No. 4489/51. Class 38 (iv). [Also in Groups XXII, XXIV and XXXVII] A drive unit for a lathe (see Group XXII), comprises a motor 32 for reciprocating a first slide 24 under the control of a pattern and tracer assembly 38, 39, a second motor 42 for moving a second slide 16, a control system for both motors actuated by switches operated by the second slide 16, and two sets of electromagnetic means, one of which controls the rate of movement of the second slide. The slide 24 carries an arm 37 bearing a tracer 38 engaging a templet 39 to control the movement of the slide through a hydraulic cylinder 32 and hydraulic power means, including an electric motor 34 mounted on the saddle 16. Movements of the saddle 16 are controlled by an electrical system which includes the motor 42, limit switches 46, 47, and dogs 49 which control a feed-varying switch 48. In operation, a control transformer and a rectifier 45 are energized by a push-button 55, a switch 62 is closed and a cycle start button 63 depressed. The button 63 energizes a timer relay T, and starts the motor 34 to supply hydraulic power to the cylinder 32. The slide 24 then moves until the tracer 38 contacts the templet 39. The timer T next energizes a relay FL to open a braking circuit on the motor 42 which increases its speed to an amount determined by means of a tachometer generator 78, a compensating potentiometer 80, the rectifier 45 and a pre-set feed-potentiometer 82 of a stepping relay SR. During the resultant travel of the saddle 16 to the left the feedvarying switch 48 in the saddle is actuated, at intervals, by the dogs 49 to bring the other potentiometers 82 into circuit in turn. On reaching the left-hand limit of traverse the saddle 16 actuates the switch 47. This switch energizes a brake relay B, to slow the motor 42, and also a timer V. The braking circuit is subsequently released, the arm 84 of the stepping relay SR is returned to its initial position, and the motor 34 is stopped to cut off the hydraulic pressure. Resistances 85 and 86 are brought into the biasing circuit 77 so that initially, the motor 42 rotates at a low speed, until the timer V operates to cause maximum speed of the motor 42. At the end of the return movement, the switch 46 is actuated to brake and stop the motor 42. A reversing switch 64 has the same function as the switch 47 so that the saddle 16 may be returned to its initial position, and the motors 34 and 42 stopped at any time. The saddle 16 may be halted at any time by a cycle stop switch 66. A cut-out switch 69 continually energizes a re-set coil 70 so that only the lowest feed potentiometer 82 is operative. The electrical switches and gauges are grouped on a control panel 121. Thus the resistances 82 and the timer T can be set on the panel and a voltmeter 87 in the feed control circuit is graduated to show the rate of feed in inches per minute.

Title: Improvements in the shrinking of textile yarns and like materials
IPC: D01D10/04
Filed: 1941-04-09
Abstract: 548,534. Artificial silk &c. ; coating yarns. HILL, F. B., and KIMPTON, W. H. April 9, 1941, No. 4720. [Class 2 (ii)] [Also in Group VIII] Textile yarns or like materials are fed at a controlled rate into the upper end of a sloping bath containing a liquid shrinking agent and withdrawn from the lower end of the bath at a rate which is lower than the rate of feeding. The slope of the bath is such as to cause the shrinking agent to flow under gravity with substantially the same mean speed as the materials, so as to allow the materials to shrink while substantially free from tension due to contact with the shrinking agent. Artificial yarns of cellulose acetate or other cellulose ester which have been stretched, or cellulose ester or ether yarns obtained by wet spinning may be subjected to the shrinking treatment. In the case of yarns of acetone-soluble cellulose acetate, the shrinking agent used may be methylene or ethylene chloride, chloroform, tetrachlorethane, or ethyl alcohol. A diluent such as kerosene may be present. As shown in Fig. 1, a number of threads 28 arranged in sheet form are fed by rollers 12, 13, into the upper end of V-shaped grooves, preferably one for each thread, formed by the corrugations of a metal sheet 6. The threads are taken from the lower end of the grooves by the rollers 14, 15. The pressures between the pairs of rollers are adjusted by screws 16. The rollers are driven by chains 20 connected to change speed gears of the positive and infinitely variable kind. The ratio of input and output speeds is adjusted to accommodate the shrinkage that occurs. Adjustable idler pulleys 22, 26 enable the tension in the chains to be adjusted. A supply-pipe 17 for shrinking fluid is provided for each of the V-grooves. The metal sheet 6 is pivoted on shaft 2, and the end remote from the pivot is supported on a rod 8 which may be secured in any desired position in the curved slot 5. In a modified construction the thread passes from rollers 12, 13 to a pulley with a V-section groove which leads the thread into the V-groove of the metal sheet at a point some distance from the edge. Similarly the thread leaves the metal sheet some distance from the lower end by passing round a similar V-grooved pulley and thence to rollers 14, 15. Specifications 177,868, 179,234, 277,089, 323,790, [all in Class 2 (ii)], 340,324, 340,325, 340,326, 340,436, 340,437, 370,430, 378,074, 378,858, and 389,823, are referred to.
