Title: Improvements relating to direct fuel injection engines
IPC: F02B19/14
Filed: 1952-04-28
Abstract: 745,635. Direct fuel injection internal combustion engines. HERCULES MOTORS CORPORATION. April 28, 1952 [Dec. 1, 1951], No. 10665/52. Class 7(3) A reciprocably mounted piston in a cylinder bore forms a cylinder chamber of variable volume with the walls and head of the cylinder bore while a constant volume mixing and combustion chamber having means for injecting fuel into the same is provided adjacent the cylinder chamber and communicates therewith through a passageway, the mixing and combustion chamber comprising a lower interiorly substantially part-spherical shell member open at the top and an upper shell member covering the opening, the lower shell member being provided with an outwardly projecting tongue of greater thickness than the shell wall proper, the tongue forming a heat collecting and conducting means. A six cylinder four stroke cycle compression ignition engine is described. It comprises front and back cylinder heads 13, only one of which is shown, each cylinder head accommodating three cylinders. Air intake and exhaust valves 35, 35<SP>1</SP> are mounted in the heads. Air intake ports 53 of each head connect at their outer end with an intake manifold 54 and associated air cleaner. In the top dead centre position there is preferably only mechanical clearance between the piston and the cylinder head. The combustion chamber comprises two parts 75, 76. the upper part being externally cylindrical and fits into a corresponding recess 74-2. and a pin 76-11 extends from a socket in the member 76 into an associated groove. A lip 76-7 is located in the transfer passage P between the cylinder and the combustion chamber and forms fuel spray deflector and gas flow directing means. The construction of each mixing and precombustion chamber provides heat collector and transfer means whereby transmission of heat to the cylinder is retarded and transmission of heat from the members 75, 76 to the cooling means is sufficiently rapid to enable the bore of the cylinder 14 to be greater than the maximum bore attainable without cylinder cracking if the member does not include the tongue 75-7 and other portion of the member 75. Fuel is injected by a pintle nozzle 83 towards the lip 76-7 and there will be a deflection of a portion of the fuel spray above and about the sides of the lip so that a portion of the fuel spray is impinged directly by the incoming air charge. The top wall 79-1 of the member 76 has a slight upward slope. The portion 75-7 of the member 75 fits a notch 81 in the cylinder 15 and the transfer passage P is formed in part by the side faces of the notch. The compression ratio of the engine may be high, e.g. 14 to 1. Each top member 76 may be welded to the associated bottom member 75. The members 75 and 76 are preferably each made of heat-resisting steel.

Title: Improvements in and relating to selective control mechanism for change speed gearing
IPC: F16H63/46
Filed: 1921-04-12
Abstract: 176,694. Alexander, A. E., (Mechano Gear Shift Co.). April 12, 1921. Controlling variablespeed gearing. - In a variable-speed gear, the change of gear is effected by bars 17, 18, Fig. 6, reciprocated in opposite directions by, say, the main clutch lever 13, Figs. 1 and 2, of a vehicle, selection being made by independent means having selective locking action when the gears are in neutral with lever 13 depressed. A lever 22. Fig. 1, connected to the lever 13 has a head 24 adapted to engage a mortise 21 in the end of the bar 18 projecting from a recessed gear-box cover 16. The bars 17, 18 are connected bv racks and a pinion 20. Striking-forks 26<a>, 27<a> are secured to blocks 26, 27 adapted to slide on the bars 17, 18. Crossbars 40, 43 are secured to the bars 17, 18 respectively, and when the pedal 13 is depressed to release the clutch, the bars 18, 17 move to the right and left respectively of Fig. 6, causing the neutralizing bars 40, 43 to come together, bring- ing the forks and blocks into the neutral position shown in Fig. 8. The selective locking device which now comes into action comprises four L- shaped bolts 30, 31, 34, 35, Figs. 7 and 9, which slide vertically in slots in the blocks 26, 27, two bolts in each block. Fingers 41, 42, 44, 45, Fig. 6, secured to the cross-bars 40, 43, extend horizontally under the blocks 26, 27, and in the neutral position, Fig. 8, a recess 46 in each finger comes directly under one of the bolts 30 - - 35. By depressing these bolts one at a time, either of the blocks 26, 27 may be locked to either of the cross-bars 40, 43, so that on release of the pedal 13, the block selected is carried in the direction selected as the cross-bars fly apart. The bolts 30 - - 35 have horizontal arms 32, 33, 36, 37, Fig. 6, which in the neutral position abut against fixed transverse stops 47, 48, Fig. 5. The depressing of the bolts 30 - - 35 is effected positively to bell-crank levers 50 actuated by separate wires 52 and push-buttons. When a button has been depressed, it remains down until the gear element corresponding has been brought back to neutral, so serving as an indicator. When a bolt such as 30, Fig. 8, has been depressed, and is carried clear of the lever 50 by bar 43, finger 44, &c., it is held depressed by the arm 32 engaging under the stop 48. The blocks 26, 27 are interlocked in neutral position by a ball 38<a>, Fig. 7, in a plate 39 between them, and are releasably locked by spring bolts 28.

Filed: 1923-04-23
Abstract: 196,921. Spirella Co. of Great Britain, Ltd., (Assignees of Wolf, F. A.). April 27, 1922, [Convention date]. Making metal fabrics; corrugating.- In a machine for making looped-wire strips for corset stays &c., a forming finger is reciprocated to and from pins carried by a pair of blocks, which are alternately moved in a direction substantially at right angles to their working faces, and which are simultaneously moved in a direction parallel to their working faces and transversely to the line of reciprocation of the finder. The wire is passed through holes 5, 6 in a head 4 and in a forming finger 3 secured thereto. The head is reciprocated by a link 7 and eccentric pin 11 on a shaft 8, which is driven by bevel gear 16 - - 19 from a shaft 15 rotated by spur gear from the main shaft 12. In order to vary the stroke of the head, the link 7 is mounted on an eccentric sleeve 9 secured on the pin 11 by a screw 10. The pin-formers 28 - - 31, Fig. 9, are carried by a pair of blocks 21, 22, mounted on arms 23, 24, which are alternately oscillated on pivots 25, 26 towards and from the line of movement of the forming finger by a pair of bars 45, 45<a> reciprocated by cam slots in a pair of discs 42, 42<a> on the. shaft 15. The arms are mounted on a slide 27 which is reciprocated in guides 33, 34 by a pair of rocking-arms 39, 39<a>, carried respectively by shafts 37, 37<a> operated by face cams on the discs 42, 42<a> through arms 41, 41<a>. The guide 33 is of wedge-shape and is moved longitudinally to vary the lateral position of the slide, the guide 34 being correspondingly adjusted by screws 36. The first loops are made by hand or by operating the machine by hand and the machine is then started. When the finger moves down with the arm 23 in the position shown in Fig. 7, the wire is bent over the pin 28 as shown. The finger then rises and the arm 24 comes forward so that the pin 30 engages the wire as shown in Fig. 9. The slide 27 is then moved to the right and the arm 23 retracted, whereupon the finger descends and bends the wire over the pin 30 to form the next loop, Fig. 11, and so on. The arms 23, 24 are held yieldingly upwards by means of springs against the heads of their pivot pins so that they may be moved down by a shoulder 56 on the forming finger to feed the fabric through the machine. The fabric is held during formation by the bevelled inner sides of a channel-shaped die 50, Fig. 4, which is carried by a presser-foot 49 pivoted on the slide, and pushed forward by a spring-pressed rod 52. The pressure of the spring 53 is adjusted by a screw-collar 54. and the rod is held from rotation by a key 55 and slot.
