Title: Improvements relating to variable speed power transmission apparatus
IPC: F16H3/66
Filed: 1937-01-14
Abstract: 480,401. Change speed planetary gearing. FREEBORN POWER CONVERTERS, Ltd., FREEBORN, J. E., DEGENHARDT, W. R., and FRAINE, A. F. DE. Jan. 14, 1937, No. 1186. [Class 80 (ii)] Relates to change-speed gearing comprising planetary trains in series, each train having an element adapted to be kept from rotating backwards by a one-way brake, on geared drive. Instead of these two-speed trains being arranged coaxially as in the arrangement described in Specification 439,855, the driven element of one train is connected by toothed gearing to the driving element of the next, so that the trains can be arranged, by the use of spur gearing, in the same plane, as shown in Fig. 1, or, by the use of bevel gearing, in mutually perpendicular planes, as in Fig. 3 (not shown). The driven. element of a train A, Fig. 2, on a shaft 10 is connected by a gear pair 46, 20b to the driving element of a train B on a parallel shaft 12, and the driven element of this train is connected by a pair 46b, 20c to the driving element of a train C on a shaft 14 in the same plane as the shafts 10 and 12. Sun gears 28, 28b, 28c of the three trains are kept from turning backwards severally on geared drives by pawls 32, 32b, 32c and detent wheels 30, 30b, 30c the thrust of the pawl in each case augmenting the torque transmitted. The gear trains shown are of the three-element spur type, but trains with stepped planets or with bevel gearing might be substituted. The geared drive in each case is on reduced speed, an annulus 20, 20b, or 20c driving, and a carrier 24, 24b or 24c of planets which roll on the stationary sun corresponding being the driven element, the carrier 24 of train A being splined to a clutch disc 38. The high speed is a solid drive obtained by closing a second clutch disc 40 carried by the driven disc 38 inwards upon a disc 36 upon the detent wheel 30 of the sun gear 28, the pawl 32 being overrun as the plate clutch picks up the drive. In the arrangement shown, the clutch is operated by means responsive jointly to speed and to load, as described in Specification 439,828. The control arrangement for the train C is shown in Fig. 1, the others being similar. Fly-weight levers 56 are pivoted on the train driven disc 38, and each lever 56 has a heel 58 through which the drive passes at all times to a lug 48 fast on a transmitting disc 52. A heavy load on the heels 58 keeps the fly-weight 56 collapsed, as shown. When the load falls off or the speed rises, the fly-weights 56 expand so as to engage and thrust radially outwards bell-crank levers 60 which thrust the clutch plate 40 into gripping engagement, bringing in the higher speed. Other lugs 49 shown are for transmitting a drive reversed. These speed changes occur in the three trains in succession.

Abstract: 667,595. Dish washing machines. FRECH, W. E.; and FRECH, M., (trading as FRECH & CO., W. E.). Jan. 18, 1950 [Jan. 21, 1949], No. 1333/50. Class 138 (i). A dishwashing and rinsing machine comprises a spraying chamber closable by a door which is coupled to a dish carrier, wherein the door is connected through flexible traction members secured to its upper and lower ends respectively, to a truck displaceable on rails, and adapted to convey a dish basket into or out of the chamber, the truck having a rear wall element which substantially closes the chamber entrance when the door is opened. The machine comprises a casing 1 in which is arranged a water trough 2. Water is supplied from the trough by a pipe 5, pump 4 driven by a motor 3, and a pipe 6 to a spray box 7 having a perforated base 8, and returns to the trough through a strainer 9. The trough is provided with an overflow 11 and the mouth of the pipe 5 is provided with a strainer 12. Above the trough guide rails 15 are arranged along both sides of the casing a wheeled truck 16 being movably arranged on the rails, and on which truck may be carried a dish basket 17. A door 19 is arranged in an opening 18 in the casing, the bottom of the door being connected to the truck by two flexible traction members 20 guided by rollers 25. The top of the door is connected by two flexible traction members 22, passing over rollers 23, 26, to a wall member 24 mounted on the truck 16. Further spray pipes 30 are arranged in the upper part 28 of the casing and a strainer 31 is located below these spray pipes. In operation the door 19 is opened by raising it vertically by means of a handle 33 and then pushed horizontally over the rollers 26 to the rear of the casing. The truck is thereby withdrawn from the casing on to a platform 35, the opening 18 then being substantially closed by the wall 24. Dirty dishes in a basket 17 are then loaded on to the truck. As the door is closed the basket is moved to a position under the spray box 7 where the washing operation is effected, food scraps being caught in the strainer 9. After a time the door 19 is partially opened so that the basket moves under the sprays 30. A control member 36 attached to one of the members 22 operates a valve 37 to cause the sprays 30 to operate and effect the rinsing operation with fresh hot water. Any remaining food scraps are removed from the dishes and caught in the strainer 31. On fully opening the door 19 the truck is again brought to a position on the platform 35. The parts 36, 37, are preferably arranged in such a way that the sprays 30 only come into operation when the truck 16 carrying dishes already washed is moved towards the platform. When the truck is fully withdrawn the sprays are automatically rendered inoperative.

Abstract: 983,973. Milling. CINCINNATI MILLING MACHINE CO. Jan. 13, 1964 [June 5, 1963], No. 1366/64. Heading B3K. A machine tool comprises a drive shaft 34 to move a slide 30, and a retraction mechanism 38 having a reversibly rotary motor 42 to drive the shaft 34 through a speed reducing gear 44 and a revolution recording mechanism 48 connected to the motor output shaft and having a positive stop 96 actuated thereby to limit rotation of the output shaft. The knee 30 of a milling machine can be raised and lowered by rotation of a hand-crank 36 the movement being indicated by a dial 50. The retraction mechanism of the invention is interposed between the hand-crank and the knee to give automatic retraction of the work on a return stroke and to restore it for a cutting stroke. The speed reducer unit 44 is associated with a lever 46 whereby the drive may be engaged, and the revolution recording unit 48 causes the fluid motor 42 to stall after a predetermined number of revolutions. The latter unit also counts revolutions in the reverse direction and then again causes the motor to stall after the same number of revolutions. Rotation of the motor shaft causes rotation of a cam lobe 100, Fig. 5, which engages a roller 102 on a lever 104 once during each revolution. The lever carries a pawl 120 engaging a ratchet wheel 126 so that, in either direction of rotation of the motor shaft 54, Fig. 3, the ratchet wheel 126 is advanced by one step at each revolution. The ratchet wheel 126 is secured to a disc 132 carrying two lobes 136, 138 which can engage a plunger 96 and force it against a spring 140 into an arcuate recess 94 in a disc 92 secured to the shaft 54. Thus the motor 42 rotates the drive shaft 34 until the cam 132 has moved the plunger into the recess in the disc to stall the motor. The cam 132 may have one, or more than two, lobes.
