Title: Improvements relating to tip carts
IPC: B62B1/24
Filed: 1945-10-12
Abstract: 602,281. Tip carts. TILKE, G. F. Oct. 12, 1945, No. 26743. [Class 108 (i)] [Also in Group II] A tipping device, particularly applicable to a wheelbarrow comprises a pair of braced side rails 1 supporting at one end the axle 4 of a central wheel 4, and at the other end formed as handles 3 and carrying supporting legs 6. The body 8 has its front wall 10 pivoted at 11 and normally secured by pivoted hooks 13 engaging pins 14. The body is supported by a roller 15 engaging inclined side rails 17 and by links 18 pivoted at 19 to the body and at 4 to the wheel axle. When the barrow is to be tipped, a keep-pin 21 is removed, and the body is moved forward, the roller 15 moving along the rails 17 and the links 18 swinging on the axle 4. The hooks 13 release themselves when the body approaches its tipped position. A sieve 23 may be fitted with wheels 24 to facilitate reciprocation along the edges 25 of the barrow.

Each valve comprises a housing 9 of brass, an opening 12 to the manifold 4, a passage 3 to the chamber 2, a valve seating 10, a valve 11, 13, and an iron core 15 at the top end. The valve 11, 13 may be in one piece, but as shown comprises a part 13 which is a permanent magnet and a steel ball 11 which adheres thereto. In the closed position shown the attraction between the parts 13, 15 is not sufficient to raise and open the valve, but by moving an electromagnet or permanent magnet 16 perpendicularly to the direction of the chambers 2, the valves 7 can be opened as required according to the size of the sheet to be printed. By reversing the current through the electromagnet 16, or if it is a permanent magnet, by turning it through 180 degrees, valves 7 can be closed as required. Two magnets 16 may be provided each operative over one half of the table. Operation of the valves may be effected by a magnet 16 underneath the table.

Title: Improvements relating to the regulation and control of saw cutting machinery and the like
Inventor: BAKER GRAHAM
IPC: B23D51/20
Filed: 1955-09-26
Abstract: 789,764. Sawing. QUALTERS & SMITH BROS., Ltd. Sept. 25, 1956 [Sept. 26, 1955], No. 27361/55. Class 145. [Also in Group XXXII] Means for controlling the operation of a saw comprises a hydraulic cylinder-and-piston assembly C, Fig. 2, a valve 16 controlling the flow of fluid through a port 17, Fig. 3, in the piston 14, a pump 24 which has a plunger P actuated by the reciprocation of the saw and is connected through valves 25, 27 to the cylinder spaces below and above the piston 14, a knockoff control for closing the valve 16 in a pre-set lowered position of the piston, and means for releasing the pressure, which is built up beneath the piston as a consequence of the closure of the piston valve, when the piston is fully raised. As shown in Fig. 1, a hack-saw bow slide 10 is reciprocated by crank mechanism 11 which also incorporates an eccentric strap 13 operating upon the plunger P of the pump 24. The rod 15 of the piston 14 is connected at its upper end to the bow slide so as to move vertically therewith. The piston valve 16 is in the form of a disc which is positioned below the piston 14 and tilted to control the port 17 by the action of a rod 18 in adjustable screwed connection at its upper end with a boss 20 engaging a rotary cam 22 on the rod 15; when the piston 14 reaches a pre-determined lower position, a lever 23 contacts a knock-off pin 29 whereby the cam is rotated to position a nick 22a therein to permit the upward movement of the rod 18 under the action of a spring 19 and thereby close the valve 16. In operation, as the saw is reciprocated, the inward stroke of the plunger P forces fluid through the valve 25 into the space below the piston 14 so as to lift the latter slightly and its outward stroke draws fluid into the pump cylinder through the valve 27. The weight of the saw assembly acting on the rod 15 forces fluid through the port 17 at a rate which is set by the valve 16 so that the drop of the piston is slightly faster than its rise whereby the saw progressively cuts through the work. When the pre-determined cut has been made, the lever 23 rotates the cam 22 to permit the rod 18 to rise and close the valve 16. The continued action of the plunger P in pumping fluid to the underside of the piston 14 forces the latter up until it rises above an orifice 30 ; the piston remains in this position until the device is re-set by pressing down the lever 23.
