Abstract: 1,136,421. Delivering sheets; cutting apparatus. WIGGINS TEAPE RESEARCH & DEVELOPMENT Ltd. 28 Feb., 1967 [18 March, 1966], No. 12034/66. Heading B6H. General arrangement.-A -web 1 of paper is fed to cutting, device 2 and sheets 3 produced thereby are delivered to continuously moving endless belts 4, 5 and then to a stacking receiver including support 11 and stop 10, the sheets being retarded before stracking by engagement of the trailing ends thereof with slower moving conveyer 14. Carriers; sheet retarding device.-As each sheet 3 leaves belts 4, 5a it is engaged on one side by a perforated endless belt 12, the sheet engaging run of which co-operates with a first suction box 13, and the sheet is thereby carried over support 11 The trailing end portion of the sheet is engaged by a perforated endless band conveyer 14, the sheet engaging run of which co-operates with suction box 15, and the sheet is thereby fed up to the stop 10. The epacing between the sheet engaging run of band 14 and that of band 12 permits the leading end of the next oncoming sheet to passs over the trailing end of the preceding sheet being moved by band 14. The trailing edge of each sheet is sensed by photo-cell 18 and a signal is passed via delay generator 20 to a solenoid operable to apply suction at box 15. Simultaneously suction is cut off from box 13. When a batch of superimposed lightweight sheets is being handled suction box 13 may be omitted and a reciprocable pad 28 provided, Fig. 3, which may be actuated by a solenoid 26a and thereby caused to move downwards, when suction is applied to box 15, to hold the sheet against band 14. In an alternative embodiment (Figs. 5 to 7, not shown) the application of suction to box 15 and the descent of pad 28 is under the control of a cam mechanism driven through a differential gear 37 by lower cutter element 2. Pad 28 may be connected to an air supply to form an air cushion between it and a sheet on belt 14 or may be a solid member provided with a rubber underside. Receivers; switches.-The support 11 may be lowered into a horizontal position to facilitate removal of a stack. Succeeding sheets may be diverted on to a second support 11a by deflector 128. Guides.-The sheets may be stiffened longitudinally by upturning their end portions as they are delivered with intermittently rotating plough elements 44, Fig. 9, which extend from the front end of suction box 15 to the stop 10. Elements 44 are caused to turn through 90 degrees at each movement and operate in timed relation to cutter 2. An initial upturning of the end portion of the sheets may be effected by providing additional stationary plough elements immediately preceding suction box 15.

Title: An internal combustion power hammer
IPC: B25D9/10
Filed: 1929-04-25
Abstract: 335,589. Luxmore, W. April 25, 1929. Percussive drills.-In an internal-combustion percussive tool, on the rearward stroke of the piston, the mixture is drawn into the cylinder 50 through a hose 81, conduits 78, 76, 44, and non-return valve 34, at the same time compressing the previous charge contained in the explosion chamber 39. The ignition circuit, containing sparking plug 38, is completed by the compressed charge acting on the pressure disc 126, forcing the stem 125 on to the contact 135. After explosion scavenging is performed by the incoming charge forced from the space 50, through conduit 45 into the cylinder 39 by the moving piston. The strength of the blow can be varied by forcing the tool stem 49 inwards against the spring 205 and thus varying the degree of cushioning of the piston by the gases entrapped in the space 50. The tool is retained by the flexible holder 217 engaging the ring 209 on the tool. The ignition circuit and the charge inlet 79 are simultaneously controlled by the thumb piece 91. Lubricant is drawn into the charge on the suction stroke from the reservoir 90, the spring valve 102 admitting air above the oil when the pressure in the space 93 falls below atmospheric. Valve 110 only closes when the plug 96 is removed to refill the reservoir 90. Valves 34 - - 36 have step members 57 on a liner 52 so that the grooves and channels 56 always provide a passage for the charge even when the valve is fully open. Starting is effected by tilting the hammer causing the piston to perform the necessary strokes, but in tools too heavy to allow for this starting is effected by a separate hand pump 317. On succeeding strokes of the pump piston the charge is drawn into the pump cylinder, then forced into the cylinder 240 below the piston, which is thus raised uncovering parts of the transfer conduit 241, and thus allows the charge to enter the explosion chamber. A second charge forced into the lower end of the cylinder compresses the first charge, and ignition then takes place as previously described. A throttle 329 placed in the transfer conduit, to allow idling in its mid-position, is raised by the handle 336 to increase speed and is depressed against its seat 332 to stop the tool. Reference has been directed by the Comptroller to Specification 330,574.
