Title: Improvements in or relating to knitting machines
IPC: D04B15/88
Filed: 1923-03-09
Abstract: 196,253. Wildman Manufacturing Co., (Assignees of Krieble, C. C.). April 11, 1922, [Convention date]. Fabric take-up and spooling devices.-Apparatus for use particularly in knitting machines for mak. ing narrow fabric comprises take-up rolls 3, driven by worm and bevel gearing 4, 5 from a pulley 7 carrying a belt 8, and a weighted lever on one arm of which a roller 12 supported in a bight of the fabric A is mounted while another arm 17 carries a belt-tightener wheel 18. When the take-up feeds the fabric down faster than it is knitted the wheel 18 allows the belt to slip. Below the take-up a spooling apparatus is mounted. The fabric after passing between the rolls 3 goes beneath a movable guide or roller 20 and up over a fixed guide 21, through a travelling guide roller 22, over a heavy roll 23 covered with sand paper and then to a spool 24, journaled in the lower ends of a forked frame 26 and mounted on a divided axle. The spool is driven by a worm wheel 28 and a worm 31 loose on a shaft 29. The worm is driven by a clutch one member 32 of which is fixed to the worm while the other 32<1> is on a splined sleeve 33 carrying a cam collar 34 and a plain collar 35. The clutch is controlled by a levar 36 carrying a block 38, Fig. 1<b>, in which are mounted two spring-pressed pins 40. When the lever 36 is turned so as to make the block recede from the clutch sleeve, the sleeve falls down the shaft 29 and at once fully engages and drives the clutch member 32. When the lever 36 is turned in the opposite direction an incline 40<a> causes the clutch sleeve 33 to ride up on the lower spring pin 40 and disengage from the clutch member 32. The clutch is then held by the upper pin 40 engaging under the collar 35 and it is thus either fully in or fully out of engagement with the worm. The lever 36 is operated by a rod 45 pivoted to a lever 46 on which is the roller 20 and is controlled by the fabric. The guide roller 22 is journaled in the forked lower end of an arm 48 which is traversed by means of a spiral cam driven by a ratchet 52 the spring pawl 53 of which is operated by a cam 56.

Abstract: 1,109,775. Jaw crushers. D. KUENEMAN. 13 Feb., 1967 [25 May, 1966], No. 6858/67. Heading B2A. A jaw crusher comprises a main box-like frame 11, Fig. 1, having at least two crushing compartments, in each of which is a stationary crushing jaw 16 and a reciprocatory swing jaw 33 having a common drive shaft 51, Fig. 2, and flywheel 72 and a connecting means between each swing jaw and an associated cam 52 to effect reciprocatory movement. The jaws are successively driven out-ofphase to equalize the loading along the structure. Eccentric cams 52 each drive a vertical pitman 54 and toggle bars 56, 57 in known manner. The pitman 54 is urged upwards by return springs 61, and the swing jaw is returned by a spring 64 and a rod 62. The fixed jaw is adjustable by spacers 25, and may have a replaceable wear face 30. The swing jaw also has a replaceable face 37 and is of arcuate configuration, and replaceable wear plates 41 are bolted to the inner walls of the side plates in each compartment of the frame adjacent to the edges of the jaws. A subcompartment, formed in each compartment of the frame and closed by a cover 66, a base plate 65 and a flexible diaphragm 67, serves as an oil sump and is lubricated by a spray pipe 68 which receives recirculated oil via a pump 69. Protection against tramp iron is obtained by connecting the flywheel to the power shaft via a leaf spring 73, Fig. 3, received in a detent 74 along the inside periphery of the flywheel, so that if a jam occurs the spring is forced out of the detent and permits the flywheel to free wheel. A second embodiment comprises a single toggle crusher in which the upper portion of the swing jaws is carried directly on the eccentric cam through large journals; two flywheels are provided to even out the cyclic loading. In either embodiment the product from one set of jaws can be fed to the next set for second or further stages of reduction.

Abstract: 584,931. Indicating liquid-levels. K. D. G. INSTRUMENTS, Ltd., and PURNELL, J. E. April 17, 1944, No. 7103. [Class 123 (i)] [Also in Group XXXVII] In float-controlled apparatus in which the float 51 is mounted on a swinging member 24 which operates the device to be controlled, the swing- ing member is mounted on a flexible diaphragm 15 carried by a wall of the liquid container in which the float is located, or on a part 11 for fixing to the wall, the diaphragm constituting the sole fulcrum for the swinging member and being stiffened along a line parallel with the axis of swing. In a float-controlled electric switch for indicating when a liquid rises or falls above or below predetermined levels, the diaphragm 15, which may be of bronze, carries on one side an arm 22 to which is attached the float-rod 24, and on the other side a plate 26 with a thin sheet-silver contact 30 which lies opposite to a contact point 42 forming part of a terminal 41. The contact 30 is also connected by a flexible pig-tail to a second terminal, not shown, parallel to the terminal 41. Flexing of the diaphragm about a horizontal axis causes the contacts 30, 42 to be closed. The diaphragm, which is accommodated in complementary recesses in a clamping ring 16 and the end wall 12 of the cylindrical casting 11, has stiffening members 18, 19 parallel to the axis of flexing and may be divided or domed. The switch may be attached to the side or, as shown in Fig. 5, to the top of the liquid container. In the latter case, the float arm 24 is bent at 54. The float and its associated parts may be protected by a tube 52. The switch may be arranged in the suction conduit of a petrol pump in an aircraft to indicate when the pump ceases to draw petrol from a tank. According to the Provisional Specification, the float arm is a rod extending through the diaphragm and through a hole in a member which is spaced from the diaphragm and carries electric contacts. The face of this member adjacent to the diaphragm has a horizontal ridge engaged by a nut or other abutment member secured to the rod. The ridge acts as a fulcrum for the nut or other member. A bridge-piece on the inner end of the rod bridges the electric contacts. Alternatively, the swinging member extends between the two parts of a bifurcated bridge which abuts the diaphragm.

Title: Improvements in and relating to Packaging Mechanisms
Inventor: FAILER KURT
IPC: B65B9/13
Filed: 1968-02-16
Abstract: 1,178,943. Liquid packaging mechanism. MIBELLE A.G. 16 Feb., 1968, No. 7700/68. Heading B8C. In making liquid filled sachets a tubular web or sleeve is filled with liquid from a storage tank under static pressure whilst being wound on to a drum, and when full, the end opposed to that through which the sleeve is filled is sealed and transferred to a high-frequency welding machine for progressive transverse welding to form sachets. Several sleeves may be operated on simultaneously, empty sleeves 13 being fed from rollers 12 on to drums 15, being plugged on to connections 14, through which liquid is forced at constant pressure from a storage tank 1 via pipes 17. Pressure is supplied by air from a compressor 24 being pumped into the space above the liquid in the tank 1 via a regulator 23. As the sleeves are filled, motors 30 rotate drums 15 to wind them on. Detectors 32 sense completion of filling and stop the drums. The filled sleeves are sealed and the sealed ends 33 are transferred to a high-frequency welding machine 34 (not detailed). The pressure on the liquid is then kept constant at a lower value. The tubes 31a are drawn through the welding machine and sealed to form sachets 37. The rotational speed of the drums is controlled by sagging along section 39 of the tubes, a contact 38 stopping the rotation at maximum sagging and starting it at minimum sagging. A regulator equivalently controlling the speed of rotation could also be used. Thus longitudinal stress in the tubes is minimized. Floats 6 and 43 are connected to bell 10 and pilot lights 9 and 45 to warn of over-filling or emptying of the storage tank. A drum may feed one filled tube to the sealing position whilst another tube is wound on another drum.
