Title: Mechanism for the delivery of tobacco to the feed mechanism of cigarette making machines
IPC: A24C5/39
Filed: 1939-08-14
Abstract: 532,049. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. Aug. 14, 1939, No. 23444. Convention date, Sept. 22, 1938. [Class 130] An arrangement for delivering tobacco from a feed conduit 17, Fig. 9, to each of the main feed hoppers C of one or more cigarette-making machines comprises an auxiliary hopper 71 mounted above the main hopper and means for controlling the delivery from the auxiliary hopper to the main hopper in accordance with the level of tobacco in the main hopper. The delivery of tobacco from the conduit 17 to each auxiliary hopper 71 is controlled by the weight of tobacco in the auxiliary hopper, and the conduit is provided with discharge valves V each comprising a tubular valve member 28 rotatable to connect the conduit with a feed opening through which tobacco is diverted into an auxiliary hopper. The conduit 17 is connected to an intake valve 16 associated with a tobacco feed table 15, and an air current is drawn through the conduit and a dust separator D by a fan F. Each of the valves V discharges through a hopper 18 having pivoted doors 50 to the auxiliary hopper 71, Fig. 10, which is pivotally supported at 69 between brackets 68 on the hopper 18. Lugs 73 on the walls of the hopper 71 are movable between adjustable screws 74 on the bracket and are normally held in the position shown in Fig. 10 by springs 72, which allow the hopper to tilt downwards when filled with tobacco. A mercury switch on one of the brackets 68 then closes the circuit of a signal light 82 at the feed table 15 and other circuits by which the discharge valve V is controlled from a hand-actuated switch 83. The discharge of the tobacco from the hopper 71 to the feed hopper C of a cigarette machine is controlled by independently yielding fingers 87 pivoted on the shaft 69 and serving to obstruct the flow of tobacco from the hopper 71 when the level of tobacco in the hopper C is at the desired working level. Each discharge valve V comprises a housing 20, Figs. 4 and 8, connected between adjoining sections of the feed conduit 17, and the tubular valve member 28 is rotatable so that its outlet end communicates either with an outlet 22 leading to the subsequent section of the conduit 17 or with an elbow diverting tobacco into the hopper 18. The air stream then passes through a screen 67 and the outlet 22 to the conduit 17. The member 28 is secured to a cylindrical member 27 turned by means of a rack 34 actuated by a piston in a compressedair cylinder connected by pipes 37, 38 to a valve 39 actuated by solenoids as described in Specification 475,870. The compressed air is also supplied to a cylinder 58 containing a piston connected by linkage 54 &c. to the doors 50 by which the tobacco admitted to the hopper 18 is discharged into the hopper 71.

Abstract: 474,541. Endless chain conveyers. GAUNT, J. G, (Vogt Processes, Inc.) Aug. 27, 1936, No. 23567. [Class 78 (i)] [Also in Group XIII] Comestibles, and particularly ice-cream bars, are refrigerated or hardened in a chamber through which they are carried from an inlet 113, Fig. 3, to an outlet 114 in an extension of the chamber by an endless-chain conveyer 80 having supports 87 for the bars and mounted on a portable frame adapted to be wheeled, in and out of the chamber through a door 131. The conveyer consists of endlesschains 83, Fig. 9, provided with cross-bars having supports 87 for the ice-cream bars, and supported on sprockets mounted on horizontal shafts carried by the portable frame. Guard strips 99 are provided around the outer runs of the conveyer to retain the bars in their supports, and the chains are driven through sprockets mounted on a shaft 68 disposed at the outer end of the chamber extension and adapted to be connected to the shaft of a driving motor by a clutch 118, Fig. 7. The portable frame is supported on rails 133 in the refrigerating compartment and maintained in position by fixed and movable stops 161, 154, Fig. 14, respectively mounted on the rails. When it is desired to remove the frame for adjustment and cleaning, the stops 154 are turned out of the path of the frame which is run over a removable rail section 144, Fig. 12, on to a fixed section 138 having pivoted stops 172 which prevent the frame moving back towards the chamber. The frozen bars may be discharged from the chamber on to a conveyer 194, Fig. 21. In another arrangement, the bars may be discharged by a pocketed wheel or roller 200, Fig. 22, on to a slide or into carriers secured to a travelling band.

Indicators actuated by pressure of head of liquid. -Apparatus for indicating depth of liquid, more particularly oil in an engine crank case, comprises a pressure gauge 3 connected by a. pipe 4, 5 to a bell 6. The piping and bell are filled with air, and its pressure is indicated on the gauge 3 in terms of depth. The bell 6 has a cover 7, Fig. 6, with a central opening 8, and the air within it is automatically replenished through a pipe 14. This pipe projects upwards through a receptacle 13 and has a restricted opening 15. When the engine is running, oil is delivered through the pipe 16 in to the receptacle 13, and in flowing downwards through pipe 14 entrains air through the upper end of the pipe, and delivers it under the bell 6. To replenish the air when the engine is stopped, another pipe 19 is provided, and the oil in the receptacle 13 gradually drains through it, finally entraining air in passing through the opening 20, and delivering it under the bell 6. Any air pressure above the oil in the crank case is transmitted through a pipe to the other side of the gauge. Specifications 268,565 and 293,251 are referred to.

Abstract: 912,156. Ash scrapers. UNION OIL CO. OF CALIFORNIA. July 11, 1960, No. 24145/60. Class 51 (1). A double-edged, straight-bladed ash scraper 11 is mounted on rails above the ash bed 15 of an underfeed kiln for the production of oil from shale heated by the combustion in the kiln of the oil-free shale residue. The scraper 11 is reciprocated from a position above and to one side of the ash bed to the other side of the kiln, so that it is not subject to great heat in the periods between its passes across the surface. Ash removed by scraper 11 falls down shoots 29, the air for combustion being preheated by its passage up the shoots 29. The ash scraper assembly may be enclosed in an airtight casing, so that air under pressure may be supplied to the shoots 29, the ashes falling through a rotary pocket valve. Shale is pushed into the kiln from cylinder 24, which is then moved to receive further shale from shoot 28, and ram 22 is retracted to fill cylinder 24. The cylinder 24 carries skirts to close the bottom of the kiln, or the shoot 28 when they are not connected to the cylinder. Instead of a scraper assembly running on rails, a scraper may be pivoted at one end to a support to the side of the kiln mouth, Fig. 3, or two scrapers pivoted one at each side of the kiln mouth may be used, Fig. 5. A single scraper may be arranged to sweep the mouths of a number of kilns arranged around the scraper pivot support. U.S.A. Specification 2,501,153 is referred to.
