IPC: A22B5/20
Filed: 1950-12-18
Abstract: 694,746. Animals heads, cleaving. INDUSTRIAL WASTE ELIMINATORS, Ltd. Nov. 15, 1951 [Dec. 18, 1950], No. 30834/50. Class 28 (ii). [Also in Group XXVI] Animal heads &c. are split by a power-operated cleaver blade 16 which moves in a straight path towards a support, each head being placed and held between spaced wedges 15 with a wood strip 12 between. The blade 16 is coupled to the end of a piston rod 21 moved down by compressed air piston 19 and raised by a piston 20. The compressed air is supplied through hand operated valves 32 and 34 both of which must be opened by an operator's hand on each for safety; on release of either of the handles 32a or 34a the lowering of the blades will be stopped and on release of both handles the upper end of cylinder 25 will be open to the atmosphere and air pressure under the piston 20 raises the assembly. The valve 34 exhausts to atmosphere through a pipe 39 if its handle only is released, whereby air pressure from the valve 32 through pipe 33 closes the valve 34f the stem of which presses on and rocks the handle 34a anti-clockwise to open the valve 34g to atmospheric pipe 39. To prevent accidental lowering of a guillotine, leakage of pressure air from the raising cylinder 26 to the top of the lowering piston 19, is prevented by a gland around the piston rod 21. Such gland comprises upper and lower U-section packing rings 42, spaced by a ring 43 spread open by wedge rings 46 and the action of pressure air through bores 47. Any leakage passes through radial holes in the spacer ring 43 to exhaust through a bore 45 to atmosphere. The pistons are similarly made air-tight by a single U-section ring and a wedge section ring spreading by air pressure.

Abstract: 1350996 Fluid pressure apparatus KUNSTSTOFF-SPRITZGUB-UND VAKUUMVERFORMUNG ROBERT KLINGER 6 July 1971 [8 July 1970] 31602/71 Heading F1P [Also in Division F2] A control block comprises three units: a distribution unit 4 (plates 1 and 2), a removable programming plate 3, and a control valve 5, Fig. 1, (not shown). The distribution unit has, on its lower plate 1, two control pressure inlets 28 which communicate with respective end chambers 27 of the control spool, two exhaust outlets 10, two working outlets 11 and a fluid inlet 8. Fluid from the inlet 8 passes to the control spool via passage 18 and to two valve elements 15 one of which (1. h. s. in Fig. 2) has a fluid bias by virtue of a connection in the programming plate with chamber 26 (r.h.s.) and the other of which (r.h.s) has the fluid bias removed by virtue of a connection to exhaust through chamber 26 (l.h.s.). Thus working fluid can pass from chamber 9 (r.h.s.) to part 11 to move piston 31 to the left. In addition a valve 14 (l. h. s) has its fluid bias removed enabling exhaust fluid to pass from chamber 30 to exhaust port 10 whilst the valve 14 (r.h.s) has a fluid bias by virtue of a connection to chamber 26 (r.h.s.) A control pressure fed into inlet 28 (l.h.s) would move the control spool to the right, reverse the fluid biasing of the valves 14, 15 and hence cause piston 31 to move to the right. Various programming plates may be inserted into the control block Fig. 5, to vary the sequence of operations. Thus, as shown, three cylinders 301, 302, 303 are operated sequentially by impulses X 1 , X 2 , X 3  applied to a pair of control valves 5. The signal at X 1  lowers piston 301, and frees the piston 302 while leaving piston 303 unaffected. X 2  then returns piston 301, locks piston 302 in the position attained under external forces, and also lowers piston 303. X 3  restores the pistons to their positions shown in the figure.

Title: Improvements in means for clamping a tool to the tool spindle of machine-tools and for ejecting the tools
IPC: B23B31/26
Filed: 1934-11-05
Abstract: 427,530. Chucks. TURRETTINI, F., 8, Rue des Vieux Grenadiers, Geneva, Switzerland. Nov. 5, 1934, No. 31710. [Class 83 (iii)] In a tool-holding socket having means for clamping or positively ejecting the tool on rotation of the socket spindle, the tool 5 has a tapered shank 4 held in a socket in the end of the machine spindle 3 by means of a clamping rod 6 screwing into the end of the shank 4. A collar 9 on the rod 6 is held between the end of the spindle and a nut 8 screwing thereon so as to rotate within the spindle without axial movement. Clutch teeth 10 on the spindle are normally pressed by a spring 19 into engagement with teeth 11 on a driving member 12 rigidly secured by pins 14 to a gear wheel 13 which effects the drive. To remove the tool 5, the spindle 3 is raised by a quill 2 and hand-operated pinion 21, causing the teeth 10, 11 to separate and the squared end 16 of the rod 6 to engage a square hole 17 in the fixed cover 18 of the casing 1. Rotation of the spindle by means of a hand tool engaging teeth 24 thereon will then unscrew the shank 4 from the rod 6 and force the shank axially out of the socket, rotation of the rod being prevented by the square end 16. To insert a tool 5, the spindle is again raised to the position shown in the Figure, the tool screwed on the rod 6, and the spindle rotated to cause the rod to draw the shank 4 into the socket. The driving train for the gear 13 may be reversible or irreversible and in the former case the spindle 3 may be splined in the gear 13 so that it remains in engagement therewith during its axial motion.
