IPC: D01H9/04
Abstract: 115,663. Stell, A., and Stell, J. May 9, 1917. Doffing-arrangements; anti-ballooning arrangements.-In cap spinning, doubling, twisting, and like frames, the dividing plates or tins are connected to the spindle rail or lifter plate, so that when the lifter plate &c. is moved for doffing, the dividing-plates are moved simultaneously. A series of receptacles to receive the full and the empty bobbins is arranged on a bar capable of movement towards and away from the spindles and also longitudinally to bring either one or the other set of bobbins into position over the spindles. The bar n, Fig. 3, carrying the dividing-plates s, the cap-holders n<1>, and the thread-guide board.o' is advanced by the rack m and segment m<2> to cause the bifurcated cap-holders to engage the necks of the caps, which have been raised into position by the spindle rail B. The full bobbins x are supported by shoes h<2> and the spindle rail B and lifter plate are lowered to free the caps which are withdrawn by movement of the rail n. The rail d<2> carrying the bobbin receptacles e is raised by the racks b<3> and advanced bv the racks c<1> to embrace the full bobbins x, which a.re then lifted off the .spindles by further movement of the racks b<@3>. The rail d<2> is moved longitudinally to bring the empty bobbins over the spindles. The racks are lowered to deposit the bobbins upon the spindles where they are supported by the shoes h<2>. The shoes are then moved to allow the bobbins to fall on to the wharles 4 and the parts brought back into spinning position. The dividing plates are hinged to brackets o' carried by the rail n and a.re connected by a chain t<2> to the spindle rail B or lifter plate 3 so that, when these are lowered for dofting, the dividing-plates are swung upwards or downwards out of the way. The chain is left slack to allow for the ordinary spinning-movements of the rail. The plates mav be arranged to collapse or fold up when they are opposite a bearer of the frame. The receptacles for the bobbins are in the form of tubes e<3>, Fig. 6, with slots c<4> in the base and the side to allow them to pass over the spindles. The base e<5> supports the flange of the empty bobbin. The full bobbins x are supported between two adjacent tubes e<3>, one edge of the part e<2> being cut away to form the slot e<4> to pass laterally over the spindle. The arms of the cap-holders have turned-up ends to retain the caps in position on them. According to Provisional Specification 6587/17, the devices for supporting the caps may be moved at an angle to the horizontal plane and further the receptacles for the bobbins have sharp edges to sever the threads. According to Provisional Specification 7963/17, the bobbin-holders may have at the upper part fingers to support the full bobbins, which when they are moved forward allow the bobbins to fall through. The empty bobbins may be held by spring arms.

Title: Improvements in or relating to document feeding apparatus
Inventor: BADENOCH ALEXANDER JOHN BARNET
IPC: B65H3/06
Filed: 1963-03-27
Abstract: 1,015,577. Feeding sheets. INTERNATIONAL COMPUTERS & TABULATORS Ltd. March 4, 1964 [March 27, 1963], No. 12087/63. Heading B6B. [Also in Division F2] Sheets or cards are fed directly by a feeding roller, or through the intermediary of a belt on the roller, by causing the surface of the roller to assume one of two radial distances from the centre of the roller so that the surface, or the belt thereon, engages or does not engage a sheet or card. The roller can be associated with apparatus for separating sheets or cards from the top of bottom of a stack, or for feeding single sheets or cards along a support. As shown, a stack of statistical cards 1 contained in a hopper 2 rests on a number of steel balls 4 freely mounted in retaining plates 3 which are rigidly supported by pillars 5. Ball races 7 in the pillars 5 support hollow shafts 8, 9 which are secured to a metal separator roller 10, the shaft 9 being driven continuously at constant speed by a belt and pulley 11. The roller 10 has a sleeve 12 of rubber or the like secured thereon, and has a radial duct 15 meeting a circumferential groove 18, and axial ducts 13,14 which communicate with ducts in the shafts 8, 9. The duct in the shaft 8 is connected with a source 21 of compressed air, and that in the shaft 9 is connected with a normally open valve 22 which can be closed by energizing an electromagnet. Normally, there is a small gap between the sleeve 12 and the bottom card 1 of the stack, and the compressed air exhausts through the valve 22. If, however, the valve 22 is closed by application of a current pulse to the operating electromagnet, the air pressure builds up inside the roller 10, and the sleeve 12 is expanded at the groove 18 to engage the bottom card 1 and separate it from the hopper 2 towards feed rollers which complete the separation. The valve 22 can be omitted, and the shaft 8 connected to a two-way valve which can be connected either to atmosphere or the pressure source 21. Further, the sleeve 12 may be replaced by a narrow ring or a portion covering only a segment of the circumference. Instead of the surface of the roller 10 engaging the bottom card, an endless separator belt passing over the roller can be caused to engage the card when the sleeve 12 is expanded. In another modification (Fig. 2, not shown), a stack of cheques or other flexible sheets rests on a number of roller bearings, and the constantly rotating separator roller comprises an electromagnet and an armature adapted, when energized, to compress a rubber &c. sleeve axially and thus cause the circumference to expand and engage the bottom card for separation from the stack. In a further application, the roller may be positioned above a flat feed table to which sheets &c. are fed singly by belts &c. The sheets remain on the table until the roller has its circumference expanded, whereupon a sheet is fed along the table to a sensing &c. device.

Abstract: 583,198. Fluid - actuated valves; hydraulic machines. ADEL PRECISION PRODUCTS CORPORATION. June 27, 1944, No. 12207. Convention date, May 22, 1943. [Classes 69 (ii) and 135] A shuttle valve comprises a housing 1 with a cylindrical bore 2 having pressure fluid inlets 5, 6 at each end and a pressure fluid outlet 7 intermediate the ends and a spring-pressed piston valve 3 slidable within the bore in response to the pressure of fluid from either inlet to close the other inlet and place the firstmentioned inlet in communication with the outlet, the piston valve carrying a packing ring 12 which is a sealing fit in the portions of the bore on opposite sides of an enlargement 13 opposite the outlet 7. The edges 14 of the enlargement 13 are bevelled to prevent injury to the packing ring as it passes over them. The piston valve 3 has a groove 11 to receive the packing ring 12 and a counterbore 15 to receive a spring 4 which normally moves the piston valve to close the inlet 6. The valve is applicable to a hydraulic system such as that shown in Fig. 8 in which a motor-operated pump 19 drawing from a reservoir 17 normally supplies fluid to the ends of a hydraulic cylinder 23 selectively under the control of a four-way valve 21 but in which a hand pump 27 drawing from the same reservoir supplies fluid to the cylinder 23 if the pump 19 fails. The outlet 7 is connected to the cylinder 23 by a pipe 24 and the inlets 5, 6 are connected to the fourway valve 21 and the pump 27 by pipes 25, 29 respectively. The hydraulic cylinder 23 is used to operate the landing gear of an aircraft.

Title: An improved device for demounting pneumatic tyres
IPC: B60C25/02
Filed: 1963-03-28
Abstract: 970,514. Demounting tyres. F. W. BRIDLE. March 28, 1963 [March 28, 1962], No. 12382/63. Heading B7C. In a device for demounting pneumatic tyres from wheel rims, in which the wheel is straddled by a frame 16 fixed to a shaft 10 extending through the hub cavity and a frame 20 movable along shaft 10, one frame engaging the rim, the other engaging the tyre, frame 20 is moved by a feed nut 22, screw-threaded on shaft 10 and carrying an external screw thread 23 of finer pitch than that on the shaft, on which a driving nut 24 is carried, nut 24 engaging the frame 20 against relative rotation. In use, the device is bolted to the wheel at 13, and as the nut 22 is turned frame 20 advances at a rate proportional to the difference between the two pitches. Frames 16, 20 are formed as spiders carrying shoes 18, 33. Initially, knuckles 26 are pivoted by cam surfaces 25 on driving nut 24, so that shoes 33 are forced against the tyre, " cracking " the bead. The detachable flange is then removed (right hand side of wheel) and shoes 18 radially adjusted to engage the tyre while shoes 33 engage the rim. Further movement of frame 20 pushes the tyre off the rim. The frame 20 carries a cam 35 engaging a keyway in shaft 10 to prevent relative rotation. The cam 35 can be made to lock the frame 20 in place while the driving nut 24 is re-set on nut 22. The feed nut 22 may directly engage the spider 20 to give faster movement of spider 20 than do the nuts in combination. The shaft 10 has a axial hole to engage a supporting tommy bar. Fig. 4 shows a modification in which shoes 33 of Fig. 1 are replaced by arrangements which lever the tyre over the rim flange. Again, leftward movement of frame 20 actuates the arrangements, which are first clamped to the wheel rim. Fig. 5, not shown, illustrates their final positions.

Abstract: 253,335. Hoffmann Manufacturing Co., Ltd., and Gannon, W. E. I. May 12, 1925. Turning balls. - Balls for bearings &c. are formed by a cutting process wherein the blanks are constrained to rotate about constantly-changing axes against one or more cutting-edges which constitute a track for the rolling blanks. The blanks A are fed into the space between the cutting-tracks BB<1>, and CC<1>. The upper track is rotated and on account of the unsymmetrical arrangement of the cutting-edges, the axis of rotation of the blanks continually changes. In a modification, Fig. 4, a number of concentric tracks are formed upon the opposed faces of a rotary disc D and an adjustable stationary disc E and the blanks may be fed to the discs as described in Specification 11504/14, [Class 60, Grinding or abrading &c.]. In a further modification, parallel straight tracks which are of different widths and are not diametrically opposed are employed, the tracks being relatively reciprocated to cause the cutting action. In some cases, the transverse rotation of the blanks against the cutting-edges may be effected or assisted by external means such as by the friction of a driving band or retarding device.

Abstract: 312,151. Waterbury Tool Co.. (Assignees of Francis, D. R.). May 21, 1928, [Convention date]. Driving arrangements.-In the driving means for sectional machines of the type wherein it is necessary to maintain absolute synchronism of speeds or a predetermined speed ratio between two adjacent machine sections, a pump and motor of a hydraulic speed gear type known as the Waterbury gear are used. The arrangement is particularly applicable to the wire cloth section and felt section of the Harper Fourdrinier paper machine and provides automatic compensation for belt slippage and for correction of the variation of speed obtained as a result of grinding or trueing-up the couch roll or wet press roll. A driven wet press roll 14 is geared by pulleys 20, 21 and belt 19 to the shaft 18 of a Waterbury gear pump A to which shaft the cylinder 35, Fig. 3, is secured. By this means water is pumped under pressure through the pipe 41 to drive the shaft 26 of the motor B. The linear speed of the idler roll 12 which contacts the wire 10 is communicated bv sprockets 52, 53 and chain 54 to the shaft 51, Fig. 3, which with its worm 50 is rotated at a speed proportional to that of the roller 12. Similarly a guide roller 17 for the felt communicates its motion through sprockets 59, 61 and the belt 60 to the shaft 58 and its worm 57 which will thus have a speed proportional to that of the rollcr 17. Any disturbance of the synchronism of the linear speeds of the wire and felt as, for example, by slippage between the felt 13 and its driving roll 14 will cause the worm wheel 49 of the worm 50 to travel faster than the worm wheel 56 of the worm 57, relative movement between a nut 47 and a shaft 45 will occur and cause longitudinal movement of a control shaft 43 of the pump to slow down the speed of rotation of the motor 13 and roll 11. When the speeds become synchronized the worm wheels 49 and 56 will again rotate at the same speed and the control shaft 43 will be held in its adjusted position-
