Title: Improvements in or relating to internal combustion engine
IPC: F02B75/28
Filed: 1946-09-13
Abstract: 630,689. Converting reciprocating into rotary motion. PARENTI, J. S. Sept. 13, 1946, No. 27550. Convention date, Nov. 16, 1942. [Class 80 (i)] [Also in Group XXVII] In an internal combustion engine having opposed pistons 10, 11 connected together (see Group XXVII) power is transmitted to a shaft 50 by means of a pair of rocker arms 55, 56 which are alternately positively connected to and disconnected from the power shaft so that the latter is rotated first by the arm 55 when the piston assembly moves to the right, Fig. 1, and then by the arm 56 during the ensuing movement to the left. Rocker arms 55, 56 extend from the main shaft, and their outer ends have bearings for cylindrical parts 60 formed with eccentric pins 59 bearing in recesses in extensions of the pistons so that the rockers may be swung about the shaft 50 by the straight line movement of the pins 59. During the power stroke of piston 10 the rocker 55 is locked to the power shaft and imparts power 'thereto during its swing of 60 degrees, the rocker 56 being disconnected. On the next stroke, the power stroke of piston 11, the rocker 55 is free while the rocker 56 is locked to shaft 50 and imparts a further 60 degrees movement thereto. Thus the power shaft rotates once for every three complete reciprocations of the piston assembly, and dead centre positions of the pistons relatively to the main shaft are avoided. For alternately locking and unlocking the rocker arms positively, the shaft 50, Figs. 5 and 6, is made in two parts connected together by bolts and each part is fitted with one or more pinions (three in the form shown) engaging internal teeth on the respective rocker arms. The short pinion shafts of each shaft portion are recessed at the ends to.provide cam portions 78 with surfaces 82 concentric with the shaft 50 and coacting with complementary surfaces 84 on a fixed cam ring 80. The surfaces 84 of the cam ring are separated by recesses 83 into which the cam portions of the pinion shafts can pass. Thus when the cam surfaces 82, 84 are in contact the pinions are locked against rotation and the corresponding rocker arm movement is imparted to'the shaft 50 but when the cam portions 78 are in the position shown relative to the recesses the pinions are free to rotate, the cam portions passing first into and then out of the recesses until, at the end of the stroke, the surfaces 82, 84 again engage for the next power-transmitting movement. A cam depression 87 on the face 84 coacts with the edge 89 of a recess to ensure that the piston assembly completes the predetermined travel and no movement is imparted to shaft 50 by the rocker arm. The fixed cams are arranged so that when one set of pinions is locked the other is unlocked.

Filed: 1922-10-13
Abstract: A homogeneous mixture of alcohol and petrol, with or without other fuel substances such as benzol, is obtained by the addition of normal butyl alcohol.  Thus a mixture of 4.75 volumes of butyl alcohol with 100 volumes of petrol specific gravity 0.729 dissolves in all proportions in a mixture of equal parts of alcohol and benzol, and 100 volumes of petrol mixed with 6.5 volumes of butyl alcohol is soluble in all proportions in alcohol.  A mixture of 100 volumes of petrol, 12 volumes of alcohol, and 10 volumes of benzol requires 2.4 volumes of butyl alcohol to render it homogeneous at 0 DEG  C., 3.5 volumes at 13 DEG  C., and 4.75 volumes at -0.5 DEG  C.  It is stated that the use of ether, castor oil, phenol, cresols, and amyl alcohol have already been suggested to increase the solubility of petrol in alcohol or alcohol and benzol.
Patent GB-616595-A (GB)
Title: Improvements in or relating to automatic guns
IPC: F41F1/08
Filed: 1946-09-17
Abstract: 616,595. Machine guns. VICKERS-ARMSTRONGS, Ltd., and HIGSON, P. R. Sept. 17, 1946, No. 27891. [Class 92 (ii)] The breech mechanism of an automatic gun having two barrels is so constructed that when one breech block is locked in the firing position the other breech block is free to recoil to permit the loading of the corresponding barrel, so that ammunition can be fired alternately from the two barrels. In the construction shown, breech-blocks 5, 6 are associated respectively with barrels 3, 4 and with sears 50, 51, operated by a single trigger 52. The breech-blocks may be retracted by handles 7, 8 against the action of springs 9, 10. Each breechblock has an inwardly-directed portion against which can bear a pivoted locking lever 12 whose free end 17 is guided in a slot 18 in the bottom plate 1 of the breech casing. An island cam 21 of triangular shape is provided on the lower face of the lever and with this cam co-operates a pintle 22 which passes through the plate 1, is secured to a plate 24 and is mounted for sliding movement against the action of a spring on a rod 27 pivoted on the baseplate 1. The slot 34 through which the pintle passes is of triangular form and is located in a recess 31 in which floats a hammer bar 30. Action.-If the unlocked breech-block 6, Fig. 1, is retracted by hand from the position shown, it engages the bar 30 which rocks about its other end in the recess 31. The bar 30 in turn moves the pintle 22 backwards against the action of spring 28A on the rod 27, the pintle first riding along the side of the cam 21 and then being swung anticlockwise, Fig. 1, by the bar. In its rearmost position the breechblock engages with a recess 30A in the upper face of the hammer bar. When the breechblock is released by the trigger, a round having been inserted in the barrel 4, the pintle under the action of spring 28A moves forwardly bearing on the other side of the cam and thus swinging the lever 12 clockwise, the pintle serving also to return the hammer bar to the position shown. Thus, when the breech-block 6 reaches its forward position it is locked by the lever 12 and its firing pin is struck by the hammer bar. On firing, the gases actuate a gas piston 42, which drives to the rear a member 43 which forces a member 45 to swing about its bearing point 48 on the now locked breechblock 6. The other end of the member 45 thus drives the breech-block 5 to the rear and the cycle is repeated. The member 43 also serves to actuate linkwork 64, 63, serving to oscillate the feed slide 60 of a cartridge feed mechanism adapted to feed cartridges from a single belt to both barrels.

Abstract: 423,454. Controlling change speed gearing. RILEY, P., c/o Riley Engine Co., Aldbourne Road, Coventry. Oct. 12, 1933, No. 28190. [Class 80 (ii)] Transmission mechanism suitable for motor vehicles comprises a pedal-controlled main friction clutch 12, Fig. 1, and a change-speed gear in two portions A and B, the portion B remote from the clutch being an " easy-change " device connected so as to be actuated mechanically by the clutch pedal 30. The change-speed gearing shown has three pairs of constant-mesh gears and yields four speeds corresponding to the changes two and two of four clutches, 19, 20, and a coupled pair 23. In the form shown, the easy-change character is derived from the two clutches 23 being frictional. In a form shown in Fig. 1, of Specification 423,455, the easy change character is derived from a tail or isolating oneway clutch 46. The clutches 19, 20, Fig. 1, of the portion A are operated in unison by integral forks 41, Fig. 2, sliding on a fixed guide which also supports a fork 40 operating the clutch pair 23. The forks 41 are connected so as to be shifted completely by moving a hand lever 39 in the plane of Fig. 2. The fork 40 is moved from the pedal 30 after a selector movement of the hand lever 39 in the plane of Fig. 3. The pedal 30 is geared to a pair of opposite cranks 34 connected to slide two bars 35 in opposite directions. When the pedal 30 is in the depressed position of Fig. 2, two notches 36 in the bars 35 are in line. The lever 39 can then be moved in the plane of Fig. 3 to bring a stem 37 into engagement with one or other of the notches 36. On release of the pedal 30, the stem 37 is carried one way or the other according to which rod 35 is engaged. The fork 40 and clutch pair 23 are thus moved one way or the other on release of the pedal according to the selective setting of the lever 39. Specification 405,429 also is referred to.
