Abstract: 357,884. Converting rotary into reciprocating motion. WILD, C. H., 401, East Oliver Street, Baltimore, U.S.A. Dec. 19, 1930, No. 38310. [Class 80 (i).] A machine for filling boxes with cans &c. of the kind comprising a shelf or shelves on which the cans &c. are formed into a load which is moved into a box by means of a plunger, the box being held in alignment with the shelves, is actuated by a relatively high-speed prime mover, e.g. an electric motor, means being provided to connect the same with the loading mechanism, causing the latter to operate with the comparatively slow movements thereof. The cans &c. roll down runwavs on to the shelves 1, the feeding being governed by gates 6 which separate the cans on the shelves from those on the runways. The motion of the machine is begun by the operator who depresses a pedal 72 which through the system 73, 75 .. 79 removes a locking latch 70 allowing a lever 59 to be swung contraclockwise about a pivot 65 by the action of a spring 68. The cam-shaped end of lever 59, Fig. 6, is thus withdrawn from the groove 62, allowing a bolt 47, spring-pressed at 51, to engage the clutch discs 28, 29 and so drive the sprocket wheel 31. The sprocket 26 is constantly driven by the electric motor 14 through the system 18 .. 21, 24, 25. When the clutch bolt has been thrown in, the chain 34 is driven and the link 35, formed with a pin 36, traverses the elongated path reciprocating the plungers 2 by the link system 37 .. 43, the plungers resting on a roller 44. When the pin 36 has completed its path and arrived back at the position shown in Fig. 1, a cam 81, rotating on a shaft 82 by means of gearing from the shaft carrying the idler sprocket 32, bears against the roller 90 on the lever 59 and moves the cam end of the same into the groove 62 to disconnect the clutch. At the same time the pin 88 on the lever 59 comes into position to abut against a shoulder 86 on the clutch member to bring the machine to a fixed position of rest each time. A catch is provided to retain, when necessary, the latch 70 in the operative position in which the clutch is maintained in its out-of-gear condition.

Patent GB-389125-A (GB)
Abstract: 389,125. Valves ; cylinder ports. CURTIS, C. G., 2, Rector Street, New York, U.S.A. July 13, 1931, No. 20032. Convention date, July 12, 1930. [Classes 7 (ii) and 7 (vi).] In a two-stroke double-acting engine with piston-controlled inlet and exhaust ports 8, 18, piston valves 20 are arranged in the exhaust pipes to close these ducts before the pistons 5 close the ports 18 ; by this means a high air charge is possible. The valves are driven by cranks revolving at twice crank-shaft speed so that each valve acts for both sides of its associated cylinder. To reduce the size of these valves two are used in each exhaust duct ; there are four ports 18 leading to each valved passage and the valves are inclined to the line of flow of exhaust. The valves are driven through bell cranks 21 to give a rapid closing movement. They leave the exhaust passages quite unobstructed when full open. Pumps.-An exhaust-driven turbo-blower supplies the air ; the blower set is placed with its axis at right-angles to the main axis of the engine. The Specification as open to inspection under Sect. 91 also describes a two-stage blower 11, Fig. 2 (Cancelled), driven by an exhaust turbine provided with a byepass 13. An electric motor 12 may be used at starting or to augment the drive of the blower during normal running. Some of the air from the blower may be used outside the engine for ventilating &c. Ports.-In a double-acting engine in addition to exhaust ports 2, 4, Fig. 1 (Cancelled), pertaining to the two combustion chambers, there is a central port 3 common to the ends ; a piston valve 6 closes the ports 2 or 4, while the main piston 5 is at outer dead centre, scavenging being effected through the exhaust port 3. Scavenging air is admitted through ports 8, Fig. 3 (Cancelled), designed to cause back flow within the cylinder in order to produce turbulence. The flow of air to the ports is unbalanced by a small piston 14 arranged to be projected into one of the side passages leading to the ports. Specifications 294,281 and 321,514, [both in Class 7 (ii), Internal-combustion engines, Arrangement &c. of], are referred to. This subject-matter does not appear in the Specification as accepted.

In a centrifuge having a screw conveyor 2, Fig. 1, for sludge discharge overflow outlets 5 for purified liquid are formed in separate members 4 which are journalled in the centrifuge rotor 1 for rotation therewith and for adjustable rotation relative thereto so as to move the overflow outlet 5 between radially inner and outer positions, common adjustment means being provided for synchronous rotation of all the members 4 through the same angle. As shown in Fig. 1, the outlet 5 of each member 4 is eccentric relative to its axis of rotation. Each member has gear teeth 6 which are in mesh with a gear ring 7 at one end of a sleeve 8 having helical splines 9 at its other end. The rotor 1 is connected to a sleeve 10 having helical splines 11 of opposite direction to the splines 9. A sleeve 12 has internal splines in engagement with the splines 9, 11 so that when the sleeve is axially displaced the gear ring 7 rotates relative to the rotor 1 thereby angularly adjusting the members 4 relative to the rotors as to alter the radial position of the outlets 5. Instead of a sleeve 12 an externally splined spindle parallel with the rotor axis may be provided. Other means for rotating the gear ring 7 relative to the rotor 1 include a spur gearing arrangement, Fig. 3 (not shown) and a level gearing arrangement, Fig. 4 (not shown). In a modification. Fig. 5, each member 4 is in the form of an L-shaped pipe portion, the extremity of the channel 5a therein defining the liquid level in the rotor and permitting, depending on its position within the rotor, complete emptying of the drum. In a further modification, Fig. 6, each member 4 is formed with a through bore 5c opening into an annular recess 4a in the member, the recess 4a forming with the rotor an annular channel 5a which is in constant communication with a liquid outlet channel 5b in the rotor. In each of the two modifications, the rotor 1 or the members 4 may be provided with means arranged in one position of the members 4 to block the channels 5a entirely so as to direct all substances supplied to the rotor to the sludge outlets. Further, the channels 5b may be formed outside the rotor end wall. The recesses 4a may alternatively be provided in the rotor end wall. In a still further modification, Fig. 8, the member 4 is provided with an approximately 180‹-extending flange which normally closes a radial opening 1a in the rotor. Counterclockwise rotation of the member 4 from the position shown allows the radial position of the outlet 5 to be adjusted while keeping the opening 1a closed whereas clockwise rotation will cause the opening 1a to be uncovered thus enabling emptying of the rotor.
