Title: Improvements in and relating to paste applying mechanism, particularly for cigarettemaking machines
IPC: A24C5/24
Filed: 1939-06-09
Abstract: 529,853. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. June 9, 1939, No. 16918. Convention date, July 1, 1938. [Class 130] [Also in Group III] In a paste-applying mechanism in which rotary members feed paste from a reservoir through a delivery duct to a discharge orifice, a conduit communicates with the delivery duct and returns surplus paste directly to the paste receiving point or points of the rotary members. As applied to a cigarette-making machine, the paste is contained in a casing 10, Fig. 3, in a reservoir 48 connected to the casing 10 by a bayonet joint. A weight 49 may rest on the paste. Paste portions are separated from the mass in the reservoir 48 by serrated edges on the blades of a rotary propeller 47. The serrations on one blade are offset with respect to those of the next blade and the blades are inclined to force the separated paste towards the inclined blades of a second rotary propeller 46. The latter delivers the paste towards an opening in the reservoir above intermeshing gears 14, 15 which carry the paste around the sides of a housing 12 and deliver it through a conduit 16. The paste is discharged on to a rotary wheel 17 and is then deposited on an adjustable bevelled wheel 18 which bears on the cigarette paper strip C. Excess paste is removed from the wheels 17, 18 by scrapers. The conduit 16 has a discharge orifice in a leather washer 50 adjacent a narrow slot in a slide 51, the slot being controlled by an adjustable gate 54 having a bevelled edge. The slide 51 is carried by a support 57 which is raised or lowered by a screw 59, having a collar engaging a slot in the support, and is held in its adjusted position by a spring 60 and locking bar 62. After the gate 54 has been adjusted by a screw 55 passing through a slot in the support 57 the slide 51 and gate 54 are clamped in position by a screw 53. The lower edges of the parts 50, 51, 54 are convexly-curved to correspond with the concave periphery of the wheel 17. The quantity of paste passing through the conduit 16 is regulated by a valve 63 and excess paste is returned through a conduit, Fig. 2, containing a spring-pressed valve 65 to a chamber 68 which discharges into the V-shaped space between the gears 14, 15 at a point where the teeth are out of mesh. To feed paste to the wheel 18 before the machine is started the gears are rotated by a hand wheel, the normal drive being first interrupted.

Title: Improvements in or relating to rotary explosion motors
IPC: F02B53/00
Filed: 1931-06-12
Abstract: 374,632. Rotary engines. AGOSTON, A., 21, R÷kk SzilÓrd Ucca, Budapest. June 12, 1931, No. 17130. [Classes 110 (ii) and 110 (iii).] A geared-vane type of internal-combustion engine comprises discs I, II, each carrying piston vanes 1I .. 6I or 1II .. 6II, which cooperate with a rotary casing III containing inlet and outlet ports for the working-fluid, and ports for taking in and exhausting scavenging air. The engine, which has no valves operates on a six-stroke principle induction, compression, expansion, exhaust, induction and expulsion of scavenging air. Two sparking plugs #1, #2, are used to give twelve working strokes per revolution. The piston disc I is fixed to a shaft A and the disc II to a sleeve B. The :rotating members A, B, C, and the casing III are supported on ball bearings. The differential motion between the discs I, II is secured by circular and elliptical gear wheels as shown in Fig. 3. The uniformly rotating shaft drives a countershaft X through gears a, b with a 3 : 2 ratio, and through gears c, d of equal diameter, the shaft Y. The latter is connected to a countershaft z by two elliptical gears e, f which cause the shaft z to be twice accelerated and twice retarded per revolution of the shaft A. The sleeve B is driven by gears g, h with a 2 : 3 ratio. A gear j on the shaft X meshes with a wheel i fixed to the casing sleeve C, the ratio being 1:3 so that the casing travels at half the speed of the shaft A. The two portions of the casing containing the sparking plugs are designed to withstand explosion pressures and contain cooling means. The casing acts as a flywheel, but the two discs I, II are constructed of a light metal such as electron or aluminium. Working fluid is supplied by a carburetter 12 to inlet ports alpha1. through the annular space between the sleeves B, C. Scavenging takes place through ports #1, #1, the air or fuel leaving the latter port either to atmosphere or to a chamber where compression is about to take place, the latter being secured by a change-over valve operated by a rod 16. The exhaust ports gamma1 may be constructed as nozzles to direct products of combustion upon a blade ring t of a turbine wheel T. The gases then flow through an exhaust pipe 18, 19 to atmosphere. Gears k, l connect the turbine wheel to the shaft Y, the wheel T and casing III rotating in opposite directions. Plugs #1, #2 are supplied with current by an ignition device 20 through slip rings. Lubricating oil is supplied by centrifugal action and by a felt oiler ring. A ratchet mechanism s prevents reverse direction of rotation when starting up. The engine may be modified to operate on a two-stroke or fourstroke cycle.
