Patent GB-536715-A (GB)
Abstract: 536,715. Knitting-machines. SCOTT & WILLIAMS, Inc. April 17, 1940, No. 6963. Convention date, May 12, 1939. [Class 74 (ii)] Relates to yarn changing mechanism in a circular knitting-machine, the general object being to provide striping control in the kind of machine in which thrust rods are used for moving yarn fingers out of action. The invention is shown applied to a machine of the type illustrated in Specification 259,529, [Class 74 (ii)]. The machine has a rotary needle cylinder 2, latch needles 4 and a number of yarn fingers 6 which can be moved out of yarn feeding position by push bars 14, acting against springs 12. The push bars 14 are urged upwardly by stronger springs 16, the upward movement being limited by engagement of shoulders 18 with a stop 20. Each bar 14 is notched at 24 to receive the arm 26 of an actuating lever which is pivoted at 28 and has another arm 30 which can be engaged by a single cam 76 on the main cam drive 32. There is also another notch on each bar 14 having a lower shoulder 34 and an upper cam edge 36. Detents 38 pivoted side by side on a pin 42 correspond to each of the bars 14 that control the yarn fingers 6. The detents are held by springs 46 against a stop 40 and in engagement with the bars 14. A yoke 48 also pivoted at 42 carries a transverse element 50 which is rocked by the action of any cam edge 36 to move the detents 38 back out of the way of the shoulders 34. Each of the levers comprising arms 26, 30 has a third arm 52 provided with sloping cam surfaces 54, 56. A bracket 62, oscillating once for each revolution of the needle cylinder, carries, on a pin 60, a series of actuators 58, each of which are provided with an upward extension 66 engageable by a transversely movable selector finger 68. When a yarn change is to be made, the follower arm 30 corresponding to the yarn finger which is going into action rides on the front surface 78 of the cam 76, the push bar 14 is lowered enough to clear its yarn finger and the new yarn immediately goes into action. The downward movement of the push bar not having been sufficient to cause the cam edge 36 to move the yoke 48, the old yarn continues in action to provide an overlap until the surface so comes under the arm 30. This causes the cam 36 to act on the yoke 48 to disengage any detent 38 from their corresponding shoulders 34 and releases all the push bars save the one which is being lowered. The released bars take their yarn fingers out of action. The cam surface 82 raises the lowered bar and releases the yoke 48 and detents 38. Yarn changes can also be made by the action of a pattern chain on the selector 68. As the bracket 62 rocks rearwardly, the upper portion 66 of a member 58 is thus selectively engaged by member 68 so that the end 58 drops into contact with and eventually gets below the arm 52. On the next forward movement of the bracket the member 58, backed by a stop 72, successively engages sloping surfaces 54, 56 which correspond to the cam surfaces 78, 80 and effects the yarn change. Specification 524,774 also is referred to.

Movement of accumulator piston 123 is limited by a stop 129 and a sleeve 121 within which a piston 122 is slidable, space 124 containing pressurized gas, e.g. nitrogen, and space 125 containing oil, the quantity of which is adjustable via port 126. Liquid under pressure enters each pump chamber 112 via a chamber 132E, having a gas-loaded diaphragm 132D, and a quick-acting inlet check valve 133, comprising a spring-loaded grid member, Figs. 9 and 10 (not shown), discharge taking place via a similar quick-acting check valve 134 communicating with an outlet chamber having an accumulator with a gas-loaded piston (136), Fig.6 (not shown). During the compression stroke of pistons 104, fuel is injected through nozzle 201 by an injection pump 200 comprising a piston 211, Fig. 18, moved on its discharge stroke by hydraulic pressure supplied beneath the piston by a free piston 263 under the control of a valve 259 actuated by the combustion chamber pressure, the stroke of piston 263, and hence the stroke of pump piston 211, being controlled by a manually and automatically controlled valve 267, connecting piston 263 to an accumulator 268, 272, to control the quantity of fuel injected. Fuel is supplied under pressure to pump chamber 212 via a check valve in inlet 231 and port 214, and is discharged via check valve 204 and nozzle 201, fuel being supplied to fill nozzle 201 before starting.  Combustion air enters engine cylinder 101, Fig.1, via check valves 143 and manifold ports 102 from compression chambers 117 behind the pistons 104, air being fed to chambers 117 via check valves 141 either directly, or from a compressor 146 driven by the exhaust gases from exhaust ports 103 when the exhaust pressure rises sufficiently to close valve 160. Pistons 104 are held in their rest positions by hydraulicallyactuated detents 170, and are synchronized by sensing the times when grooves 119 are uncovered by their respective pump plungers 113, and using the pressure signals so produced to adjust the pressures in respective accumulator chambers 125 to adjust the return pressures on the piston assemblies. A spring-loaded, inertia-actuated piston 115 within pump plunger 113 pumps oil through passage 164 to the engine piston rings 166. A control system for starting and stopping the engine is described, including hydraulicallyactuated detents and valves for preventing starting until the correct system pressure is reached, Figs. 27 and 41 (not shown).
