Abstract: 301,780. Humphris, F. June 27, 1927. Passes, mechanical.-Comprises lever pressureexerting mechanism for presses and other machines. Fig. 1 shows a toggle mechanism in which a series of at least four parallel bars bare connected to another similar series c through the medium of a third series of axially-moving bars d, toggle links a forming the spacing members between the bars of each series. There are at least two sets of links provided, each set comprising at least three links mounted on a common axis. As illustrated. five sets of links are shown, with provision for a sixth. The ends of the bars may embrace and slide on guide frames shown in dotted lines. Fig. 7 illustrates a modification for use where the head room is limited. In this case the links are curved and pass in each case from the remote side of the centre bars to a point near the edge of the top or bottom bars respectively. A main actuating toggle also is shown in dotted lines for moving the bars d axially to actuate the links. Fig. 9 shows a further modification in which two sets of bars b, c only are employed, the set c acting as a ram member and the set b moving axially to operate the ram and also taking the thrust Rollers e<3> facilitate the axial movement of the bars b in this case. In all cases the sets of parallel bars can be arranged in groups spaced apart where necessary to accommodate other parts of machines, the bars d, Fig. 1, for example, being fitted in two sets with a larger intermediate spacing instead of all being spaced by the thickness of a link Specification 301,779 is referred to.

Abstract: 1,213,264. Housing pigs. ARGAL S. A. EMBUTIDOS Y CONSERVAS. 2 April, 1969 [19 Aug., 1968], No. 17248/69. Heading A1M. A building for housing pigs has automatic feeding, watering and dung clearing means. The stable has two rows of pens 1 defining a control passage 1a along which a feeding hopper 3 travels, and two dunging passages 1b. A control room 1c is isolated from the stable by automatically controlled motor driven doors 25. The feed hopper is filled from silo 24 by a screw conveyer (24a), Fig. 7 (not shown), the filling being controlled by a micro-switch. The food supply is regulated by a turbine 19, Fig. 9,in a shoot (23), Fig. 8 (not shown), of the hopper 3. The turbine is rotated by a star wheel 14 turned by pegs 15 in rail 16 which control the quantity of food dispensed. The star wheel drives turbine 19 via gears 17 and shaft 18. The star wheel has a ratchet so that food is only supplied as the hopper moves away from the control room. Water is supplied, for mixing with the food, from tanks (7), Fig. 6 (not shown), in each pen. The water level in the tanks is controlled by adjustable ball valve (34a). As the food hopper advances a roller 11 carried by an arm 9, Fig. 5, mounted on the feed hopper 3 actuates a valve 38a via a plate (12), Fig. 6 (not shown) in order to supply water to the food in the trough. The roller only actuates the valve when in position b, Fig. 5. When the feed hopper reaches a position remote from the control room, arm 9 is raised by a stop 13. On returning to the control room, arm 9 is lowered by stop 13<SP>1</SP>. Dung channels 1b, Fig. 1, are cleaned by scraper blades 30, Fig. 7, carried on trolleys 29. The scraping action occurs in one direction of movement of the trolleys only, the blades being brought into and out of engagement with the floor by means of stops 33, 33<SP>1</SP>, at each end of the dunging passage. The feed hopper 3, Fig. 1, may be driven by steel cables 4, Fig. 3 (not shown), or by an electric motor on the hopper. The dung trucks are driven by endless belts passing over pulleys 27<SP>1</SP>, 27.

The drum 3 is a double drum including a hub for winding the cable 1 and co-axial hub winding a guiding and earthing wire 2, the two hubs being rotatable in mutually opposite directions by a spring or hydraulic motor 9, the drum axis extending vertically up from the vehicle movable over a horizontal surface. The drum is vertically adjustable in the vehicle. The supply 13 is a plug-in connection for the cable 1 and wire 2 and when the wires are changed from one to another plug-in connection, the two drum hubs are locked together by a pin, to remove tension in the cable and wire, this pin normally being stored in a socket in the vehicle to operate an activating switch whereby the vehicle cannot be moved until the pin is back in the pocket. Rollers are provided to guide the cable and wire to and from the drum. Limit switches provide indication to the vehicle driver that the wire or cable are almost fully payed out. In the embodiment of Fig. 5, for an increased area of operation, the cable 1 and wire 2 extend from the vehicle to opposite ends of a trolley 21 rollable along fixed overhead rails 23. A further double drum 25 is journalled at one end of the rails 23, from which drum a cable extends for connection with the cable 1 at one end of the trolley and a wire 29 extends for connection with the wire 2 at the other end of the trolley, the wire 29 first passing around a reversing pulley 30 at the remote end of the rails 23. In the embodiment of Fig. 8, for an even greater area of operation, the cable 1 and wire 2 extend to opposite ends of a trolley 21 rollable along fixed overhead rails 23 which incorporate electrical conductor bars 32 slidably engageable by current collectors 31 on the trolley. In the embodiment of Figs. 10 to 12 (not shown) a single hydraulically driven drum is used for a cable only in an arrangement as shown in Fig. 1. In further embodiments of Figs. 13 to 18 (not shown) the arrangements are as shown in Figs. 5 and 8 but both the cable and wire drums are rotatable in the same direction by hydraulic motors.
