Title: Improvements in or relating to automatic weighing and packing machines
IPC: G01G13/00
Filed: 1929-02-09
Abstract: 325,986. Steimel, P. Feb. 9, 1929. Filling sacks.-In an automatic weighing and packing machine in which the movement of a control lever from weighing to packing position relieves the sack-holder and starts the packing mechanism, the control lever is secured in packing position by a locking mechanism adapted to be disabled by a movable rack that is operatively coupled to the packing mechanism upon movement of the control lever to packing position, and is returned by gravity after causing the release of the lever. At the completion of a weighing operation, the sackholder 3, Fig. 1, is raised from the weigh-beam (not shown) by depression of a handle 4, the consequent rotation of a lever 7 forcing a second lever 8 into engagement beneath an abutment on the sack-holder. The lever 7 is maintained in its relieving position by a latch 13 engaging beneath, an arm 12 of the lever. Simultaneously with the raising of the sack-holder, a link 10 connected to the handle 4 causes the members of a clutch 11 to engage, and thereby start the packing mechanism. The members of a second clutch 15 are also caused to engage, whereby a pinion 18, meshing with a verticallyguided rack 19 (shown in raised position), is coupled to the packing mechanism and causes the rack to rise and ultimately trip the latch 13 to allow the path to return to normal position under the action of gravity. The duration of the packing operation is proportional to the height through which the rack has to be raised to trip the latch, this height is controlled by a pin inserted in holes in a guide 20 and forming a stop for the rack in its downward movement. The latch 13 may be tripped manually by depression of a lever 30 to stop the packing mechanism. In a modification, Fig. 4, a weighted arm 22 is lifted during the weighing- operation and is held in raised position by a pawl 23. At the end of the weighing operation, a stop 24 on the weight-support 2 trips the pawl 23 and allows the arm to return to the position shown, which movement raises the sack-holder 3 and causes the actuation of the packing-mechanism and rack 19. The extent of movement of the rack is controlled by a nut on the rack co-operating with a guiding abutment.
Patent GB-348193-A (GB)
Title: Improvements in change-speed mechanism
IPC: F16H61/02
Filed: 1930-02-10
Abstract: 348,193. Variable-speed gearing. SCHOTTLER, G. T., 258, Brockley Road. Brockley, London. Feb. 10, 1930, No. 4512. [Class 80 (ii).] _ Variable-speed epicyclic gearing comprises a planet-carrying casing 4 fast on the driving-shaft 2 which casing drives a governor which functions to control the speed of driven shaft 3 by exerting braking pressure on a control sun gear 11. There are interengaging planets 8, 9 with terminal gears 7, 10 meshing respectively with the control sun 11 and with a sun gear 17 splined at 18 on the driven shaft 3. When shaft 2 starts to revolve, as when the engine clutch of a vehicle is engaged, a shaft 26 carrying governor 28 is set revolving, and also sun gear 11 is set revolving faster than shaft 2 in the same direction. Governor 28 exerts a braking action in gear 11 to control the speed automatically, either by a clutch 41 slidable on shaft 2, or by a brake 16. In the arrangement shown, the clutch gears up to direct drive, and the brake gears up beyond that. An air pump 53 constantly driven from shaft 26 replenishes a reservoir, not shown, through duct 54. Compressed air is delivered from reservoir through duct 56 to distributing valve 55. To engage the drive, or change up, the engine is accelerated. The speeded-up governor 28 through lever 35 turns valve 55 to admit air to cylinder 62, which through linkage 47 engages clutch 41 so as to diminish the rate at which gear 11 runs faster than shaft 2. If the driver wants a higher speed than direct drive, he releases clutch 41 by opening a valve 67 and closes a valve 66, whereupon, on speeding-up the engine further, valve 55 sends air to cylinder 59 applying brake 16. Reversed driving is effected, by sliding two pairs of gears, 17, 67<1> and 601, 611 to the right. The reversed drive passes through train 25, 601, 61<1>, 63', 681, 67<1> to shaft 3.

Title: Improvements in and relating to stripping mechanisms for tobacco leaf stemming machines
IPC: A24B5/06
Filed: 1935-02-14
Abstract: 456,839. Tobacco stemming machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Feb. 14, 1935, No. 4755. Convention date, Sept. 6, 1934. [Class 130] In a tobacco-stemming machine in which the leaves are drawn between two rotary stripping devices, having stripping members which act repeatedly on the leaves, each rotary stripping device is provided with a knife which coacts with the knife of the other stripping device to sever the stem of the leaf at a predetermined point. Tobacco leaves are placed on a belt 10 and the butt ends are stripped by a thresher T while the leaves are grasped between belts 10, 13. To ensure that leaves of different thickness will be grasped, spring- pressed rollers 19 are held against the belt 10. After leaving the thresher T, the butt ends are held between twisted chain conveyers, which turn the leaves into a vertical position, where they are gripped by fingers G and carried between stripping devices mounted on shafts 27, Fig. 2. Each stripper is formed by carded bars 22 supported between heads 25, 26 on the shaft 27. The bars, after acting on a leaf, are caused to recede by levers 30 actuated by a stationary cam 33, and the bars are set so that, upon engagement with the leaf, two bars 22 either follow each other, as shown in Fig. 2, or mesh with one another. The stems S are severed when their thickness does not exceed that of the cross veins by knife blades 39 on a star wheel 40, the cutting edges of the blades on one shaft 27 being inclined and bevelled in the opposite direction to those on the other shaft 27. The wheels 40 have keys 41 projecting through the shafts 27 into shafts 43 which can be adjusted simultaneously, while the machine is in operation, by racks 47 engaged by gears 46 on a common manually adjustable shaft 45. The position of the knives is indicated on a scale 49 by a finger 48 carried by the rack 47. In the modified construction shown in Fig. 9, the knife 52 on one shaft has a pair of spaced cutting edges between which the knife 51 on the other shaft enters, and stripping is effected by notched blades O.
Patent GB-267106-A (GB)
IPC: B65G53/66
Filed: 1927-02-21
Abstract: 267,106. Fuller Co., (Assignees of Etablissements Poliet et Chausson.) March 6, 1926, [Convention date]. Pneumatic conveyers.-In a conveyer system in which pulverulent material contained in a storage chamber 28 is forced through a pipe 33 by a screw pump 29 and compressed air supplied at the end of the pump, the means for regulating the supply of compressed air is controlled by the speed of the pump. A cylindrical member 5 attached to the hollow extension 1 of the pump shaft puts a chamber 11 into communication alternately with a chamber 19 and the hollow shaft. Compressed air is admitted to the chamber 19 by a pipe 16 and by a very small orifice 17 to the shaft. The air passes from the chamber 19 to the chamber 11 during nearly a half revolution of the shaft, and during the next half revolution expands through the port 14 into the shaft and through the nozzles 18 into the pipe 33. The volume of air thus admitted may be varied by adjusting the piston 12. The nozzles 18 are kept clean by the air admitted through the orifice 17, and compressed air is admitted to a chamber 22 by the pipe 21 in order to avoid conveyed material coming into contact with the journal 8. A pressure regulator 30 is inserted in the pipe 33 and varies the pump speed by actuating a rheostat 31 which governs the speed of the electric motor 32, or similar devices such as brush shifters or gas inlet regulators. The regulator may actuate also a safety valve which returns the material to the suction side of the pump when the delivery falls below the minimum corresponding to the speed below which the pump no longer works efficiently. When the system is used for feeding pulverized coal to a number of furnaces 39, a series of valves 36 controlled by chains 37 are provided on the pipe 33 and control the supply of fuel to the burners 38 supplied with air by blowers 40. A safety valve having an overflow is provided. Fig. 4 shows the conveyer utilized for filling sacks 50 or barrels 51 with pulverized material.

Abstract: 490,753. Hydraulic brakes. HYDRAULIC BRAKE CO. Feb. 19, 1937, No. 5038. Convention date, Feb. 20, 1936. [Class 103 (i)] An hydraulic master cylinder comprises a flexible cup 50 as described in Specification 486,935 for producing a slight pressure in the pipe system during release, and a valve 66 which provides a direct communication between the pipe system and the master cylinder when the brake is being released. The valve 66 comprises a hollow stem passing through the flange 52 of the cup 50 and a flange 72 engaging the piston 60. When the brakes are applied, ports 80 in the stem 66 pass the flange 52 and are in direct communication with the pipe system, so that, on release, the fluid of the system urged by the brake shoe return springs passes through the hollow stem, forcing back the piston 60 which separates the flange 72 therefrom and discharges into the master cylinder. The stem 66 also returns until the parts 80 are covered whereupon fluid returning from the system lifts the cup 50 and passes into the reservoir. The spring 82 bearing on the valve 66 returns the piston finally drawing fluid from the reservoir 10 past the cup 50.

Title: Improvements in Electric Motor Controllers.
IPC: H02P1/16
Filed: 1918-03-22
Abstract: 119,405. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). March 22, 1918. Controllers with auxiliary switches.-A controller has speed-regulating and starting devices operating upon a common resistance and the degree of automatic acceleration by the starting device is dependent upon the setting of the speedregulating-device. The motor A has series and shunt field coils F, F<1>, and the starter 2 has arms 6, 7, 8 angularly spaced round a shaft 5 rocked by an electro-magnet 12. The field circuit switch 13 is closed when the starter is in its off position. The speed-regulating device consists of a switch arm 17 with contacts 18, 26, 31, 34 working over segments and studs connected to the armature resistance R and field resistance R<1> as shown. The closure of the push-button 45 energizes an electromagnet which closes the main switch 1. Assuming the regulating switch 17 to be in the position shown in dotted lines, the motor starts up with all the resistance R in the armature circuit, and the electro-magnet 12 causes the arms 6, 7, 8 to cut out the resistance. The switch 13 opens when the starter operates and the shunt field circuit is completed through the contact 26 on the regulator arm 17. Any predetermined amount of the resistance R' may be included in the field circuit by moving the arm 17 counterclockwise. The closing' of the starter arm 8 is not effective unless the contact 18 on the arm 17 has reached the segment 25; similarly, the closing of the starter arm 7 is not effective unless the contact 34 on the arm 17 has reached the segment 33. The starter can therefore only control the resistance to the left of the speed-regulating arm 17.
