Filed: 1954-05-26
Abstract: 754,586. Strikers for locks and latches. ROETHEL, J. H. May 26,1954, No. 15510/54. Class 44. A striker device for co-operation with a pivoted latch bolt 13 mounted on the edge of a swinging door and of the kind having at one side of its pivot axis a portion adapted to engage a pin 53 on the striker device and at the otherside of its pivot axis a curved portion 49 having a centre of curvature coincident with the said axis comprises a plate portion 50 terminating at one end in a flange 51 including an ascendingly convexly curved section 55 merging into a concavely curved section 56 having a centre of curvature substantially coincident with the pivot axis of the latch bolt when the door is closed, the plate portion carrying the pin, which is engageable by the latch bolt to effect pivotal movement of the latter as the door is closed, the arrangement being such that upon closing of the door, the curved portion 49 of the latch bolt first engages the ascendingly convex section 55 of the flange during pivotal movement of the latch bolt and then comes to rest in engagement with the concavely curved section 56 of the flange, thereby maintaining the latch bolt against vertical displacement relative to the pin 63. The portion adapted to engage the pin consists of two spaced arms 47, 48. If the door edge carrying the bolt is displaced below its normal position the engagement of the portion 49 of the latch bolt with the convex section 55 of the flange urges the edge of the door upwardly so that the pin 53 latches correctly between the arms 47, 48. The flange may be resilient to urge the latch bolt into tight engagement with the pin 53.

A tobacco handling machine in which a prepressed tobacco stream having surplus. tobacco is supplied to a trimming device for removing the surplustobacco ischaracterized in that a pressing device is provided which engages the tobacco stream and which abuts the trimming device and is constructed to compress the tobacco more strongly than the prepressing device. A tobacco stream is fed by a belt 16 into the perforated base of a groove in the periphery of a driven feed wheel 1 and; is compressed first by the belt and then more strongly by aroller 30 abutting the trimming device and consisting of a cutter disc 50 and a toothed wheel 51. The tobacco is retained; by suction acting through the portion 15 of the feed wheel, in the groove and passes under the belt 62 to rod forming means. The roller 30 and'the trimming device are mounted on a carrier 33 which is adjustably supported on a housing portion 38. The pressure exerted by the roller 30 is varied by adjusting a screw 41 acting on one end of a spring 42 acting on the roller pivot arm. The motor 56 driving the spindles of the trimming device is displaceable in. slots 80 to vary the height of the trimming device independently of the roller. A pneumatic duct 81 returns the surplus tobacco to the distributer. In a modification the upper part of the belt 16 is replaced by suction acting through the base of the groove in the feed wheel and the pressure exerted by the roller is varied by a weight on a threaded rod on the roller pivot arm. The pivot arm may be resiliently supported on the carrier by two blade springs at right angles, the spring connected to the arm engaging in a cut out in the other spring connected to the carrier. In a further modification tobacco is blown from a duct on to the lower surface of a perforated conveyer belt and is pressed thereon by suction applied above the belt. The tobacco passes over a brushing roller and then the compressing roller which abuts the trimming device. The tobacco passes under a measuring device which signalsvariations in density and controls the height of thetrimming device corresponding to the density. In a further modification the-tobacco is conveyed on the upper surface of anendless belt to beneath a suction conveyer and. passes over the pressing roller abutting the trimming means before being conveyed to the rod forming means.

Title: Improvements in apparatus for supplying measured quantities of liquid
IPC: G01F11/02
Filed: 1937-06-08
Abstract: 496,954. Delivering measured quantities of liquids. KILBY, A. E., and HAYWARD, TYLER, & CO., Ltd. June 8, 1937, No. 15858. [Class 106 (v)] A predetermined quantity of liquid is isolated by allowing the liquid pressure to act on both sides of a differential piston device and the measured quantity is then delivered by allowing the pressure to act on one side of the piston only. Fig. 1 shows one form of measuring apparatus in which a cock 4 is first turned to allow liquid to flow from a tank 2 to the underside of a piston 5 so that if the piston is moved into engagement with an adjustable stop 8. The cock 4 is then turned to shut off the flow of liquid from the tank 2 and to allow liquid to flow from below the piston 5 into a bottle 9 under the pressure of the liquid in the tank 2 on a smaller piston 3 connected to the piston 5. The space between the pistons 3, 5 communicates through a hole 7 with the atmosphere. Figs. 2 and 5 show another form in which the liquid from a pipe 20 can flow through a cock 21 and passage 22 to the space 6 between two differently sized hollow pistons 18, 19 and, when a cock 24 is in the position shown, through a passage 25 to the space below the piston 19. The consequent upward movement of the pistons is limited by stop 34 carried by an adjustable screw cap 33. When a bottle 9 is pressed against a conical head 30, the head 30 is moved upwardly against spring pressure and, through a link 29, turns the cock 24 to close the passage 25 and to allow liquid to flow from below the piston 19 through a passage 27 and filler tube 26 to the bottle. The plug of the cock 24 is normally retained in position by a spring 28 which may be swung aside to allow the plug to be removed for clearing. The piston 19 slides in a glass sleeve 11 which is visible through an aperture 10<1> in the body 10 of the measuring device.

Filed: 1950-06-27
Abstract: 706,401. Controlling automatic weft replenishment. SMITH, H. G., and SHACKLETON, G. W. June 27, 1950, No.. 15983/50. Class 142(2) Initiating bobbin changing, Fig. 5. In a loom having a drop box at one end and bobbinchanging mechanism at the other (single box) end, energization of a solenoid 5 by a weft feeler at the drop box end causes its plunger 4 to erect a catch 3, as shown, whereby the need for replenishment is stored and bobbin changing is effected next time the depleted shuttle enters the single box. The catches 3, one for each cell of the drop box, are circumferentially spaced round a sector 1 which is swung about its pivot 2 by the dobby acting through mechanism (described below) independent of the change-box mechanism, so that the catch corresponding to to the active shuttle lies above the solenoid. This catch, when erected, lies in the path of a feeler 36 on an oscillating lever 34; when the feeler encounters the catch, its tail 37 lifts a finger 38, carried by a lever 40, into the path of an oscillating frog 44; the lever 40 is thereby turned to initiate bobbin changing. As the lever 40 turns, a link 47 depresses a finger 45 pivoted at 34a on the lever 34 so that, as the lever 34 swings to the right, the finger flicks the catch 3 to its normal horizontal position. Operating colour selector, Fig. 3. A member 21 actuated by the pattern lags brings one or other of two reciprocating hooks 16 into engagement with pins 15 on a gear 14, whereby a gear 13 is turned to bring a crank pin 12 to top or bottom dead centre. Two such mechanisms are used, their pins 12 being coupled by links 11 to opposite ends of a floating lever, an intermediate point of which operates the sector 1, Fig. 5, and also the colour selecting mechanism of the bobbin magazines, as in Specification 595,591, so that the magazine is always ready to supply a bobbin appropiate to the shuttle available for replenishment.

Title: Improvements in or relating to apparatus for automatically adjusting the clearance of a motor vehicle clutch
IPC: F16D25/08
Filed: 1968-04-03
Abstract: 1,223,333. Clutch release mechanisms. DAIKIN SEISAKUSHO K.K. 3 April, 1968 [19 April, 1967; 12 May, 1967 (2)], No. 16104/68. Heading F2L. Wear compensating apparatus for the gap between a clutch release yoke 21, Fig. 1, and a release bearing 20 comprises a release cylinder 5 having first and second flow paths arranged so that depression of the clutch pedal 1 causes the yoke 21 to close the gap a and disengage the clutch, a switching valve 6, 8, 11 closes one of the flow paths at the moment the yoke disengages from the bearing thereby obstructing return movement of the release piston 23 and a piston 13 in the release cylinder allows the release piston to recede an additional amount proportional to the gap which is thereby maintained regardless of any wear at the clutch facing. Depression of pedal 1 causes oil flow through duct 4 and passage 18 into chamber 24 causing downward movement of piston 13 which in turn causes oil flow from chamber 7 into the release cylinder 3, the piston 23 being moved to the left to disengage the clutch. Clearance b disappears as yoke 21 contacts the release bearing 20 and as further oil enters chamber 12 the valve member 11 is raised to allow oil to flow directly into the release cylinder via ports 7, 6 so that the release piston is moved further to the left in the clutch releasing direction. When the pedal is released the action of springs 25, 30 moves the release piston to the right. When the yoke 21 disengages from the release bearing spring 8 overcomes spring 25 causing the valve member 11 to move to the Fig. 1 position in which the oil flow via port 6, chamber 12 and port 7 and further return movement of piston 23 is prevented. Spring 15 is compressed as the piston 13 rises allowing a further movement of the release piston 23 to maintain the gap a. In another embodiment the piston (13), Fig. 4 (not shown), and valve member 11 are in separate cylinders in a housing 5, the gap being maintain in the same way as in Fig. 1. In a further embodiment depression of the clutch pedal causes the release piston 23a, Fig. 6, to be moved to the left and pressure oil passing through piston 13 also causes the latter to be moved outwardly. Further depression of the clutch pedal causes the yoke 21 to engage the release bearing, valve member 11 being lifted and oil flows via ducts 7, 6a, 6b to move all pistons 23a, 13 and 23b outwardly into the Fig. 6 position. When the clutch pedal is released springs 25, 30 return the release piston 23a. Until yoke 21 separates from the release bearing 20 valve 11 remains in its upper position so that pistons 13, 23b can return whilst maintaining clearance b. After the separation the valve member 11 descends to close duct 6b preventing any further return of the release pistons 23b, but piston 13 and therefore piston 23a is permitted to return by an amount equal to the clearance b to form a gap between the yoke and the release bearing.
