IPC: F01L5/04
Abstract: 106,721. Wall, A. W. Aug. 3, 1916. Regulating; valves.-Combustible charges are supplied to the cylinder a by a pump b into which liquid fuel is drawn through a valve l and at the end of the suction stroke air is admitted through the transfer passage f and ports j, k. The pump is shown applied to a two-stroke-cycle engine, its piston d being attached to the main piston c and its charges injected into the cylinder at the end of the instrokes through a port n. The piston d carries a ported sleeve valve g which works between the pump barrel b and a stationary sleeve h depending from the head of the pump i. There is a safety valve o in the plunger. The richness of the charge is controlled by varying the compression of the fuel valve spring q. When applied to a four-stroke-cycle engine the pump is driven by a crank or eccentric and finishes its stroke before the piston. The charges enter the cylinder through a port over-run by the main piston. The pist m may form the barrel of a lubricating-pump.

Abstract: 1422627 Moulding food products HOLLYMATIC CORP 11 March 1974 [5 July 1973] 10727/74 Heading B5A A food patty moulding machine operable without substantial pause includes a hopper 11 from which food is forcibly delivered by a reciprocatory ram 18, Figs. 7 and 8, to a mould plate 14 having mould openings 15 and horizontally reciprocated between mould filling and patty discharge positions, the mould movement is out of phase with the ram movement such that the mould moves from its filling position before the ram completes its pressure cycle. The mould is attached to bars 29 reciprocated by a linkage on each side of the machine including a rocker arm 19 pivoted at 20 connected to a mould plate drive link 26. Each arm 19 is driven by a link 21 pivoted to a link 22 driven about a shaft 23 by a drive 79. The arms 19 also drive the ram through a linkage on each side of the machine including a link 33 pivoted about a pin 35 on the drive link 22, a link 36 pivoted at 37 and a link 40 pivoted to a ram drive bar 42. The latter, Fig. 7, are interconnected by a bar 43, and the drive to the ram 18 is imparted via a bar 48, bolts 49 and springs 50. The out-of-phase relationship desired between the ram and mould plate is provided by the angular relationship of the operating links of the respective linkages. The hopper includes an intermittently rotated feeder for dislodging material from its inner walls, such feeder being driven by a strap 62, Fig. 2, driving a crosshead 63 which drives the feeder shaft via a ratchet and pawl mechanism. A patty knock-out mechanism 66 is lowered when the mould plate has moved to its discharge position and is urged constantly to its lowered position by springs 97. The mechanism is secured to vertically movable shafts 110 at each side of the machine slidable in brackets 111, 112, and includes a bar 99 with knockout cups 92. The bar 99 is attached to side members 101 secured to shafts 103 slidable in flanges 102, each shaft carrying a collar 104 which, when the mould plate is fully extended drops into a groove 105 in a block 106 attached to a bar 29. Each shaft 110 carries a roller 72 running along an edge 71 to keep the mechanism in a raised position. The edge is extended by an edge 73 of a spring- urged lever 74 pivoted at 76 to the position of Fig. 3. With the mould plate in the patty discharge position the roller 72 on each side of the machine drops from the edge 91 of a lever and the collars 104 engage the grooves 105. Return movement of the mould plate causes each roller to ride up a cam edge 78 and rotate a lever 74 clockwise until its edge 77 coincides with the edge 71; on further return movement the rollers pass on to the edges 71 to allow the levers to spring back to the position of Fig. 3. The knockout device is thereby raised and the collars 104 lifted from their grooves. Each groove has a tip 107 which engages a collar during movement of the mould plate to its discharge position whereby the knockout mechanism is carried forwardly with the mould plate.

Patent GB-114876-A (GB)
IPC: H04M15/28
Abstract: 114,876. Bruschke, G. I. April 13, 1917. Meters. - A telephone metering device comprises two counters, one of which is operated to count the number of completed calls, and the other to count the number of uncompleted calls. The counters are independently operated by the cores of two solenoids which are polarized by a magnet, one core being moved when a positive current is sent from the exchange and the other when a negative current is sent from the exchange. In the arrangement shown, the core U, Fig. 3, of a solenoid R and the core V of a solenoid S are polarized by a magnet M. The core U is connected by links W, E to the arbor F of a. counter C; while the core V is connected by links W<1>, E<1> to the arbor F<1> of a counter D. The line from a generator K at the exchange is connected to a hinge Z of the meter box, from which a lead L passes to the upper ends of the solenoids R, S. The lower ends of the solenoids are connected by a lead T to a pivot I of a bell-crank lever P, the short arm of which is adapted to be engaged by a contact J when a push B, Fig. 2, is operated. The contact J is connected to earth through leads G. When a subscriber wishes to make a call, he operates the push B thereby connecting the solenoids R, S to the exchange. If the operator is able to connect him to the called subscriber, he operates a reversing switch X to send a positive current through the solenoids R, S. The cores R, S are then magnetized so that their lower ends have south polarity and the core V is repelled by the south pole of the magnet M to operate the counter D. The energization of the solenoids R, S also causes the attraction of the long arm of the lever P whereby the short arm of this lever is caused to release the button B and the contact J. If the operator is unable to complete the call he sends a negative current through the solenoids R, S, when the core U is caused to operate its counter C, and the button B and contact J are released.
