Title: An improved internal combustion engine
IPC: F02B53/00
Filed: 1956-08-30
Abstract: 841,198. Radial-cylinder four-stroke engines;; cam driving-gear; cylinder scavenging, cooling and construction; combustion chambers; ignition valves. CASINI, C. R. Aug. 30, 1956 [Sept. 14, 1955; Nov. 9, 1955], No. 26465/56. Classes 7(2), 7(3) and 7(4). [Also in Group XXVI] Driving-gear. Cam surfaces 39, 40, Figs: 5 and 6, of a stationary (or rotary) casing 1 and on which rectangular pistons 8 radially mounted in a rotary (or stationary) cylinder block 6 react via rollers 34, 35, are circular arcs, centred on the engine axis over a portion CD corresponding to combustion at constant volume and a portion FA corresponding to scavenging at constant volume. Over the portion CD the surfaces 39, 40 are laterally stepped to provide alternative cam tracks affording differing compression ratios and with one or other of which the rollers 34, 35 are aligned by sliding of each roller mounting 33, in a dovetail etc. connection 9 with its piston 8, at an unstepped point of the surfaces 39, 40, e.g. in that portion AB corresponding to intake. Such sliding may be effected mechanically or electrically from a foot throttle; Fig. 4 shows rollers 36 on the mounting 33 acted on by plungers 44, 441 via parallelogram lever linkages 42, 421 pivoted on casing side plates 24,241. Cylinders. The casing side plates 24, 24<SP>1</SP> each have inlet and exhaust ports 30, 28, Fig. 1, coacting in turn with ports 22 in cylinder block end plates 15, 15<SP>1</SP> and shaped as shown in Fig. 8 to correspond with the cylinder combustion chamber cross-section substantially at T.D.C. The plates 24, 24<SP>1</SP> mount sparking plugs 44 which ignite a combustible mixture charge through the ports 22 or may be replaced by fuel injectors if an air charge is used. The plates 24, 241 also have ports 29 which, when they align with a pair of ports 22, allow air from a fan 52 to scavenge the respective cylinder. The fan 52 also blows cooling air through tubes 14, Fig. 5, traversing inter-cylinder water jackets 13 in communication through ports 23 with water supply and exhaust compartments formed in a hollow cylinder block support shaft 20 by a partition 50, Fig. 6. The fan 52 may blow air into the tubes 14 via a duct. Water-cooling may be dispensed with, air being blown through inter-cylinder ducts 13, Fig. 8, narrower at their exit than at their entry so that air passes via the ports 23 to the shaft 20 which is unpartitioned and also receives air from the fan 52 direct; cooling fins parallel to the air flow may be provided. The ports 22 have seals 32, Fig. 6, which may be forced against the plates 24, 24<SP>1</SP> by spring or cylinder-gas pressure. Pistons. Each piston 8 has one or more piston rings 16, each in four equal parts which may be suitably joined, and which are pressed into operative contact by spring or cylinder-gas pressure. Lubricating. The casing 1 forms an oil bath and ducts through the plates 24, 241 lubricate the seals 32.

Abstract: 925,494. Swaging. FENN MANUFACTURING CO. July 21, 1961 [April 26, 1961], No. 26471/61. Class 83 (4). A metal workpiece is swaged by two pairs of opposed dies operating in alternate sequence in radial slats of a cylindrical support 16 having a central feed opening and an outer cover ring 30. The dies 36 are non-rotary and have workengaging faces 38 which may be flat, of concave or convex shape, or having ridges or depressions ; different work-engaging contours may be provided on adjacent or opposite dies or both. Shims 42 separate the dies 36 from hammers 40 whose outer surfaces 78 are engaged by rollers 52 of a rotating cage 50. The dies and hammers are guided radially by bearing shoes 26 in the stationary support 16 and the stroke position of the dies is varied by altering the thickness of the shims 42. Lubricant is fed to the dies through a passage 80, Fig. 1 (not shown), and is retained by seals 88, Fig. 1 (not shown).

The conveyer 17 has a lining 19 of felt so that the cigarettes can be gripped without being damaged. The conveyer 15 runs at a slower speed than the belts 17, 18. The stack of cigarettes which thus forms on the conveyer 15 is held down by a member 50 pivoted at 51. A guide member 48 is pivotally mounted at 49. The conveyer 15 comprises chains 41, 41, spaced on either side of a stationary surface 45 of wood, steel or plastic laminate. The chains 41 have spaced recessed links 41, the alternate spaces and recesses corresponding with the spacing and shape of the cigarettes. The conveyer 15 feeds the hopper via a vibrating shoot 53. This is vibrated by a member 57 (Fig. 6) connected by a member 59 to a lever 64 oscillated by a rotating cam shaft 66. The latter also oscillates an agitating member 69 inside the hopper. The member 59 carries further agitating members 81. The cigarettes fall from the shoot 53 on to driven rollers 73 mounted above respective fixed guide members 74. The rollers 73 all rotate in clockwise direction except for the two at the extreme right (as viewed in Fig. 5), which rotate anticlockwise. Photo-cells 107, 108, 109, respond to the height of cigarettes in the hopper and control the speed of the packaging machine 12 accordingly.
