IPC: B21J7/24
Filed: 1951-04-03
Abstract: 712,832. Fluid pressure hammers. BELLOWS, CO. April 3, 1951 [April 3, 1950], No. 7690/51. Class 122(3) A valve mechanism for a fluid pressure hammer having a piston operating in a cylinder having detachable heads at either end thereof, one of the heads having an opening therethrough, comprises a cylindrical casing abutting the head having said opening, an element reciprocating in the casing to open and close said opening, and a valve controlled opening in the said element. A piston 26 operates in a cylinder 21 closed at its ends by detachable heads 22, 24 having apertures 23, 25 respectively therein. Axially outwardly from each head 22, 24 is a valve mechanism H, J comprising a casing 35, 55 having reciprocably mounted therein a disc 37, 57 which carries on its inwardly facing side 42, 59 an annular seal 43, 60 for seating on the associated head 22. 24 and has a central aperture controlled by a non-return valve which is a spring loaded lift valve 38 and an annular flexible lip type valve 58 for the discs 37 and 57 respectively. A piston rod 28 secured at one end to the piston 26 passes through the head 24 and disc 57 and is attached at its other end to a tool head retained in position by a latch operable by a piston and cylinder release mechanism. Exhaust from either end of the cylinder 21 takes place through the openings 23, 25 and exhaust ports 50, 71. A slide valve 80 controls fluid supply to the valve mechanisms H, J through ports 83, 88 and ports 84, 89 and 90 respectively. Port 88 also communicates via a passage 96, a spring- loaded valve 97 and a conduit 95 with the cylinder of the piston and cylinder release mechanism. To make a power stroke valve 80 is manually moved to the right against a spring 85 to supply fluid to the valve mechanism H whereupon disc 37 is moved downwards to seat on head 22 and close opening 23 and valve 38 opens to admit fluid to the cylinder 21. When the pressure in cylinder 21 is sufficient to lift the valve 97 the piston and cylinder release mechanism is operated to release the tool head and allow it to be driven downward by the piston 26, the compression under piston 26 unseating disc 57 to allow exhaust through port 71. To lift the tool head, the control valve 80 is allowed to return under the action of spring 85 and fluid is supplied to the lower end of the cylinder 21 through valve 58 after disc 57 has seated on head 24; the fluid above the piston exhausting through port 50 after the pressure has risen sufficiently to lift disc 37.

Abstract: 731,113. Automatic alignment control systems. BUNZL, H., SCHECHNER, P., and CIGARETTE COMPONENTS, Ltd. April 28, 1954 [March 24, 1953], No. 8134/53. Class 38 (4). [Also in Group VI] To compensate for stretch in superposed webs 10, Fig. 2, wrapped in a garniture 14 round spaced filter plugs delivered on to the webs by means 28 (see Group VI), the resulting continuous rod being cut centrally of the plugs and spaces therebetween by a rotary knife 38 to form cigarette filter tips, the rate of delivery of the plugs to the webs is varied relative to the instant of cut of the knife by adjustment via a servo mechanism 49 of the speed ratio of a gear 41 driving the means 28. Photo-electric cells 59, 62 actuated by light respectively passing through the interplug spaces and a slit in a disc 60 on the knife driving shaft 42 produce signals fed through respective amplifiers 64, 65, Fig. 7, to an adding circuit 66 whose output is fed to a relay 67 including switches 68, 69 operated alternatively to supply control voltages to the servo mechanism 49. The signal from the cell 59 is arranged to give the basic wave form A shown in Fig. 8c, and, when the knife 38 is cutting centrally of the plugs and spaces therebetween, the pulse signal from the cell 62 is positioned at Y relatively thereto and adds to this wave-form to give a voltage Y<SP>1</SP> to which the relay 67 is not responsive. Relative movement of the signal from the cell 62 to a position X or Z gives a voltage X<SP>1</SP> or Z<SP>1</SP> to which the relay 67 responds to close a respective switch 68 or 69 and restore the signal to the position Y. The circuit is supplied with power from a source 70 via a time-sharing circuit 71 arranged to permit and prevent operation of the servo mechanism 49 in some predetermined sequence, and which may be a thermally-operated relay or a switch actuated by a cam driven by a synchronous motor or by some continuously rotating member of the apparatus.
