Title: Apparatus for the degreasing or other cleaning of workpieces
IPC: C23G5/04
Filed: 1957-07-11
Abstract: 857,151. Degreasing work objects. DREYER, J. A. July 11, 1957 [July 19, 1956], No. 22064/57. Class 82(2) A vapour phase degreasing apparatus contains, in the lower portion of the degreasing chamber, a condenser formed by a fall pipe which causes a rapid condensation of vapour on the termination of the vapour degreasing process. As shown, vapour chamber 1 contains basket 4 (Fig. 2) into which are placed the work pieces; this basket is raised and lowered by means of ropes 5 and rollers 7 which are actuated by motor 11 and controlled automatically by means of switches 17 and 18 which are operated by nut 16 on rotation of shaft 8. Vapour chamber 1 is closed by means of lid 3 and contains condenser 28, above which is provided a double wall cavity 33 which, opens into chamber 1 through slots ,34; any vapour not condensed by coils 28 is drawn through these slots by means of fan 29 and exhausted through 35. In the lower part of the vapour chamber 1 is located fall pipe 36. Towards the end of the process, as the vapours rise up chamber 1, thermostat 49 is caused to operate valve 46; this allows some of the cooling water which enters coils 28 at 45 to be run through pipe 47 to fall pipe 36, whereby a very rapid cooling and condensation of the vapours in the lower portion of chamber 1 is effected. At the same time as thermostat 49 operates valve 46 it also operates to cut off heating elements 40 situated in a shallow trough 39 and immersed in solvent, e.g. perchlorethylene, at the base of chamber 1. As the vapours condense, valve 46 is closed by thermostat 49 and the fall pipe 36 is drained; on subsequent raising of basket 4 for unloading, no vapour is carried up by the basket. The base of chamber 1 slopes so that all sludge settles in trough 39. Trough 39 may be emptied by means of hand pump 39 and access may be had for cleaning purposes by removing access lid 41 to which are attached elements 40 and thermostat 56, which latter is provided to prevent overheating.

Title: Improvements in and relating to rotating shears
Inventor: HENSCHKER ERHARD RUDOLF
IPC: B23D36/00
Filed: 1952-09-05
Abstract: 736,599. Shearing. LOEWY ENGINEERING CO., Ltd. Oct. 12, 1953 [Sept. 5, 1952], No. 22338/52. Class 83 (4). In a shearing machine in which rotary shears are stopped after each cut, a main motor which drives the shears during cutting and a pilot motor which returns the shears to their starting position are connected to the shears through clutches operative alternatively. Operation of a flag switch 21 by the stock energizes an electromagnet 5 which clutches a disc 6 so that the normally running main motor 1 drives the shears 8 through the cutting position.. A rotary limit switch 18 de-energizes the electromagnet 5 and energizes an electromagnet 15 which clutches the disc 6, whereupon the shears are slowed by a brake 17. After they have passed the starting position, a limit switch 19 energizes the pilot motor 11 which slowly reverses the shears 8 to the starting position where a switch 20 operates the brake 17 and de-energizes the electromagnet 15.. After a predetermined time the electromagnet 5 is again operated and the cycle repeated. In a modification the switch 19 becomes operative before the shears reach the starting position and the pilot motor 11 drives them slowly forwards to this position.

Title: Improvements in and relating to variable-speed gearing
IPC: B60K17/08
Filed: 1931-08-07
Abstract: 387,016. Variable-speed gearing; ratchet clutches. HOLLOWS, L., 44, Parr Street, St. Helens, Lancashire. Aug. 7, 1931, No. 22351. [Class 80 (ii).] In variable-speed gearing for motor vehicles, employing free-wheel clutches at least at the higher speed, a pinion B, Figs. 1 and 2, on the driving-shaft A engages quadrants d on levers D<1>, D<2> pivoted in a free cage C and frictionally engaging an outer driven drum F. In a second free-wheel clutch, Figs. 3 and 4, the levers 3a, 3b engaging the pinion 1 on the shaft A carry rollers 2a, 2b which are adapted to be brought, by axial movement of the inner parts of the clutch, into alternative engagement with oval or other non-circular drums 6A, 6B. An operating-sleeve M, Fig. 1, actuated by a pedal a, Fig. 6, has lost-motion connection with the axially slidable cage C, its lugs m<1> engaging lugs d<3> on the levers D<1>, D<2>, when these latter are withdrawn axially from the drum F, so as to prevent their radial movement. When the cage C is returned to the position shown, the inner surfaces d<1> of the levers engage a camplate H on the drum F so that the levers are expanded, to initiate frictional action, against the action of spring L. While the drum F overruns the shaft A, the frictional action is insufficient to transmit appreciable torque with normal pressure upon the pedal a. When the shaft A accelerates, the pinion B rotates the levers to clutching position. This clutch may, however, be replaced by any other type of clutch. A positive free-wheel drive is similarly obtained in the high and second speed clutch, Figs. 3 and 4, in which, however, the springs 4 assist clutching action and bevel-edged rollers 2a, 2b on the levers 3a, 3b engage non- circular surfaces on drums 6A, 6B during movement to operative position. The clutch, Fig. 1, drives the low-speed pinion G constantly engaging a pinion 8, Figs. 1 and 3, on the layshaft 10. The clutch, Fig. 3, drives alternatively the second-speed drum 6A, geared to the lay-shaft gear 5a, and the high-speed drum 6B secured to the driven shaft T. A double pinion 9 is slidable on the shaft 10 by a fork 11 to engage directly with the drum 6B, for forward reduced speeds, or through idlers 12 for reverse, this movement being possible only when the clutch, Fig. I, is engaged within the drum F by depression of a pedal a, Fig. 6, secured to the rock-shaft Q against the action of a spring ql. The pedal a is pivoted to a link b sliding on a pin e and provided with a hole bl engaged by a rod dx carrying the gearlever c, so that when the latter is in the position shown it can be moved to operate the clutch, Fig. 2, through a push-rod 13a for second and top speeds, while the clutch, Fig. 1, is locked out of gear ; with the gear-lever c in either of its left-hand low-speed and reverse positions, the pedal a can be moved to engage the clutch, Fig. 1, and by increased pressure upon the pedal, the pressure of the levers D<1>, D<2> upon the cam H becomes sufficient to lock the clutch for engine braking.
