Title: Improvements in or relating to machine guns
IPC: F41A19/33
Filed: 1928-03-13
Abstract: 306,069. Werkzeugmaschinenfabrik Oerlikon. Feb. 15, 1928, [Convention date]. Machine guns. - Two separate handles are provided to operate a trigger mechanism by means of two separate firing knobs, one handle causing single-shot, firing, and the other handle automatic firing. As shown, a casing 3, Fig. 1, in rear of the breach casing 1 contains a sleeve 4, Fig. 6. in which two claws 6 are pivoted on pins 5. The rear ends of the claws 6 are urged apart by a spring 7, which causes the front ends of the claws to engage a hook 8 at the rear end of the breech-block 2 thereby to hold the breech-block in the retracted or cocked position. The sleeve 4 is cushioned by a spring 9 against the shock resulting from the arrest of the breech-block by the engagement of the hook. The claws may be locked in this engaging position bv an elliptical safety member 10<a>. or may be unlocked by the turning of this safety member through 99‹ by means of a bolt 10. The front ends of the claws 6 are guided in a. piece 14 secured inside the sleeve 3, and between these ends of the claws 6 two firing knobs 18<e>, 18<d>, Fig. 8, are pivoted in line with the pivots 11 of two levers 12<e>, 12<d> with handles 13. A cam 16 is made fast with the firing knob 18<e> and is engaged by the tooth 19<a>, Fig. 4, of a cam 19 pivoted at 20 on the lever 12<e>. The cam 19 is normally held in engagement with the cam 16 by a spring 21, and the lever 12<e> is normally held forward by a spring plunger 22. If this lever is pulled back by its handle, it rotates the cam 16 and therefore also the firing knob 18<e>, but at the end of the stroke, the cam 19 is deflected by the fixed wall w and releases the cam 16; the result of this isthat a single shot is fired and then the claws 6 again retain the breech-block. The other lever 12<d> is similarly provided with a cam 25, Fig. 5, engaging another cam 24 fast with the firing knob 18<d>, but in this case the fixed wall v does not. daflect the cam 25 sufficiently to release the cam 24, and firing proceeds automatically until the lever 12<d> is released, or until the magazine M, Fig. 1, is empty. When this occurs, a spring blade f on the follower Z of the magazine rocks a lever 28, which pushes a rod 29 back against a spring 31. The tail end of the rod 29 comes to bear on a concentric part 25<c> of the cam 25 and rooks this cam sufficiently to release the cam 24, whereupon the claws 6 are again free to engage the hook 8 and hold back the breech-block.

Patent GB-622424-A (GB)
Title: An improved means of applying lubricant to rails and wheels of railways
IPC: B61K3/00
Filed: 1947-03-21
Abstract: 622,424. Force-feed lubricating. HURRELL, G. C. March 21, 1947, No. 7866. [Class 12 (iii)] For lubricating rail heads, grease is contained in two reservoirs 1 secured to the rail and is transferred to the rail head by means of a reciprocating pump 7 which is actuated by the weight of the passing vehicle. The reservoirs 1 containing weighted pistons 2 resting on the grease 3 are secured to a box-like member 5 which is bolted to the web of the rail and are connected by a hollow member 5A having communicating ports 6. The pump 7 is mounted on the member 5A and comprises inlet and outlet ball valves 8, 24 and a piston 12 urged towards the open end of cylinder 11 by a spring 13. The outward movement of the piston 12 is limited by an arm 14 hinged to a member 15 frictionally mounted on a rod 18 which is driven into the railway road bed and which will not be appreciably moved by the passing of trains over the track. In operation the vehicle weight causes deflection of the rail and consequent downward movement of the pump body 7 relative to the piston 12, thus drawing a small quantity of lubricant through the port 6 and valve 8. When the vehicle has passed, the pump assembly rises and the piston 12, being constrained from moving by lever 14, forces the lubricant through valve 24, discharge passages 25, 26 to the rail face 27. Some of the lubricant may be byepassed through a hand-regulated throttle 28 to the supply. The relative positions of the co-acting elements of the pump may be adjusted by axial movement of member 15 on rod 18, the limiting positions being defined by stops 20, 21 or adjustable stop 22. Specifications 481,194 and 564,908 are referred to.

Title: Improvements relating to washing apparatus for ore, clinker, gravel and the like
IPC: B03B5/56
Filed: 1922-03-18
Abstract: 193,711. Hughes, T. March 18, 1922. Rotary washing-apparatus. - Apparatus for washing ore &c., of the kind comprising a rotating drum on the interior of which are fixed longitudinal partitions which raise the material and allow it to fall on to a series of inclined plates which feed the material forward for further agitation and washing, is provided with circumierential partitions so as to form a number of compartments surrounding the stationary grid. The material is delivered by means of a hopper 15 into the first inclined compartment 12 between the inclined plates 11 of the grid and falls into a circumferential compartment such as 17 formed by the longitudinal partitions and the annular partitions 6 of the drum 1. The partitions and the body of the drum are preferably perforated, and the drum, which is rotated by horizontal supporting rollers driven by a pulley 4, is partly immersed in water or other cleansing liquid contained in the trough 9. The finer particles pass into this trough and are removed together with the water by means of a valve 20. When the water in the trough 9 rises above a predetermined level and enters the pipe 35 the disc 32 is forced downward, causing the chain 31 to engage the arm 23 of a pawl with a projection 29 on the rod 24. The latter is connected to a rotary crank-disc 27, and on its upward stroke sets the valve 20 in its open position. When the level of the water falls the spring 30 restores the pawl to its original position, and during the next succeeding downward stroke of the rod 24 the projection 28 engages the arm 22 and recloses the valve. The coarser particles are carried forward by the grid and are subjected to repeated agitation and washing, being finally discharged by the shoot 16.

Title: Improvements relating to fuel injection in oil engines
IPC: F02D1/00
Filed: 1931-03-18
Abstract: 367,595. Oil engines. PACKARD MOTOR CAR CO.. Detroit, Michigan, U.S.A. March 18, 1931, No. 8311. Convention date, April 19, 1930. [Class 7 (iii).] When starting and during slow running a fuel pump is operated at a faster speed relative to the speed of rotation of the engine than during normal working. In a radial ninecylinder Diesel engine, fuel under low pressure is circulated in a manifold 22 by a pump (not shown), any excess fuel being returned to the source of supply. Each cylinder is provided with a pump 29 to which fuel is admitted through a port 33 overrun by a plunger 31, and the fuel withdrawn from the manifold by each pump is forced past a non-return valve 32 into the fuel injector, in which is a spring-pressed valve 26 normally held open by an adjustable stop 27. The pump plungers each carry a rod 36 which bears on a lever 41, adjustment of the stroke of the plungers being effected by links 37 connected to the rods 36 and also to a ring 38 controlled by a rack and pinion 40. Mounted on the crank shaft is a cam 45 which is oppositely driven through internal toothed gearing at one-eighth the speed of the crank shaft and provided with lobes for actuating the cylinder valves through push rods 47 and pivoted levers 46. A central snail cam 44 is fixed to the crank shaft and actuates the pump plungers through bell cranks mounted on the cam 45 and having arms 54 which project through peripheral orifices 53 in the cam. Springs 56 bear on the bell cranks and during starting and slow running act quickly enough to move the arms 54 from their rearmost to their forward positions in the orifices 53 during contact with the levers 41 and thereby impart to the pump plungers a rapid impulse stroke. During normal running, the speed of the cam 45 is sufficient to force the arms 54 into contact with the levers 41,-while they are at the rear ends of the orifices 53 and before the springs 56 can move the arms forward. By this action a slower stroke is given to the plunger than during starting and slow running. Leaf springs 58 fixed to the arms 54 cushion them during their forward stroke.
