Abstract: 134,786. Dickinson, W. June 24, 1919. Roll holders and cases.-The ends of an axle d, carrying a roll of velvet &c. are journaled in twopart bearings at the ends of the box, the bearings being adapted to be opened or closed by the pressure of the axle in the act of removing or inserting it. The parts a<1>, a<2> of each bearing are pivoted at b to the ends of the box, and are secured together by a lever e pivoted in the part a<1> and notched to engage a pin e<3> in the other part a<2>, the end of the lever being bent at e<4> to engage a slot c' in the end of the box. The ends of the parts a<1>, a<2> are chamfered at a<3> so that pressure of the axle d thereon opens the bearing; further pressure of the axle on the lower corners of the bearing-grooves a<4> closes the bearing. When the lever c is released, upward pressure of the axle forces the bearing apart. The lower ends of the bearing are chamfered at a<5> to allow outward movement. In a modification, the pivots b engage slots in the parts a<1>, a<2>, the sides of the parts being engaged by guides on the ends of the box in the closed position of the bearing but being drawn clear of the guides to allow the bearing to open when the axle is raised.

Title: Improvements in or relating to relay action electric switches, more particularly foruse in conjunction with fluid pressure systems
IPC: F15B21/08
Filed: 1943-08-23
Abstract: 568,427. Fluid-pressure servomotorcontrol systems. AUTOMOTIVE PRODUCTS CO., Ltd., and CLENCH, E. C. S. Aug. 23, 1943, No. 13735. [Classes 69 (ii) and 135] [Also in Group XXXVII] An electromagnetic switch 65, which has main contacts 66, 67, 68 controlling a motor 11 driving a pump 10 in a hydraulic system; has retaining contacts 69, 70, 71 and an operating coil 72 and is associated with a controlling device consisting of a handle 34 movable either way from a central position and two contacts 56, 57 which are successively engaged when the handle is moved, the contact 56 being in series with contacts 69, 70 and the contact 57 in ' parallel with the contacts 69, 70. The handle 34 is returned to its central position by a spring 39 and also serves to operate a valve 18 admitting pressure fluid driven by the pump 10 to one side or other of a piston 29. Movement of the handle rotates a metal disc 51 permanently connected through a contact 55 with the coil 72 and the line 62. The contact 56 is situated in a narrow gap in the disc and the contact 57 in a wider gap so that operation of the handle either way causes the disc to engage first contact 56 and then contact 57. Engagement of contact 56 produces no effect, since contact 71 is disengaged, but engagement of contact 57 completes a circuit through the coil 72 to earth. The switch 65 then closes all its contacts and the motor drives the fluid through pipe 24 or 25 to'the hydraulic device. When the handle moves back the coil 72 remains energized through retaining contacts 71 till the contact 56 is disengaged at the very end of the stroke of the handle. In a modification, the handle operates a Y-shaped member which drives one or other of two metal slides carrying projections which successively engage contact springs.

Abstract: 1431058 Feeding sheets; sheet ordering apparatus GUTERNIC AB 22 March 1973 [23 March 1972 23 Jan 1973] 13736/73 Heading B8R Sheets 11 are simultaneously separated from a plurality of piles supported on shelves between partitions 3 and directed along channels 13 to a single receiver 41 where they form a collated set. Separation is effected by a plurality of friction separators 4 which raise each endmost sheet to a position where a flap 10 may engage the remainder of each pile thereby directing each endmost sheet away from the piles and into the channels as the separators execute a return (downward) movement. The separators are reciprocated over the faces of the piles by parallel arms 15 which are oscillated along slots 8 by disc 39 and link rod 35. The separators are lifted from the piles upon completion of their downward movement by engagement with teeth of a rack 1. The flaps 10 are normally held out of contact with the piles by arms 21 and the teeth of a rack 2. Upon upward movement of the separators 4 the arms 21 are pivoted away from the flaps and the rack 2 is moved by electromagnet 6 to release the flaps which are brought into engagement with the piles by springs 9. Upon downward movement of the separators the engaged sheets are directed by the sloping surfaces of flaps 10 into the channels 13. Continued downward movement of the separators is accompanied by pivoting of arms 21 to lift the flaps from the piles and a return of rack 2 to lock the flaps in their inoperative position. The collated sheets are aligned by a vibrator 42. Between the delivery of each set into the receiver 41 by rollers 30, 31 the receiver is rotated through 90 degrees to form distinguishable batches.

[Also in Division B6] Apparatus for feeding a sheet or the like to an ironer comprises a pair of swingable members 23, 24 pivoted at the left-hand input end of the apparatus as shown in figure 1 by means of universal joints on the ends of a driving shaft 25 for driving conveyer chains 32 having grippers 106-108 carried on the members 23, 24. These members 23, 24 each comprise a horizontal arm 28 and a vertical part 29 and are supported intermediate their length by casters 35 running on a track 37. They are biased apart by springs 56, 57 in a damping cylinder 50 acting through a cord and pulley system 46-49 on one member, on equal and opposite movement being conveyed to the other member by another cord and pulley system 38, 39. The grippers 106-108 comprise strips-secured at one end to the chains so that they open when passing around the sprockets 27, 30, 31 but are closed elseqhere and co-operate with a microswitch 109 to stop the conveyer chains momentarily with one gripper at position 106 open. Whilst the chains are stopped an operator inserts the corners of the leading edge of the sheet in the grippers 106. The conveyer chains then restart and carry the sheet along under the lower runs of the chains and spreading it whilst so doing against the tension of springs 56, 57 acting on the arms 28. The sheets are drawn across a wire lattice 144 and billowed out by air from a blower 113 and delivered on to a transfer roll assembly 73-77 driven by belts from a motor 88, this operation being assisted by air from another blower 114. The rolls 73-77 are provided with spiral beads so that a friction drag is provided tending to spread the trailing portion of the sheet. When the grippers 106 reach the sprocket 31 at the delivery end of the apparatus the sheet is released and delivered by the transfer rolls on to conveyer tapes 80 of the ironer. Roll 75 is arranged to rotate reversely and acts to apply friction drag after the leading edge of the sheet has been gripped by a doffer roll 81 on conveyor 80. Alternatively, raising of roll 75 by the operator can divert a torn or defective sheet downwards between rolls 74 and 75 and away from the ironer.
