Title: An improved clutch and brake
IPC: F16D67/04
Filed: 1942-12-16
Abstract: 562,146. Hydraulic clutches. RHODES, C. J., and RIDGWAY, H. Dec. 16, 1942, No. 17893. [Class 69 (ii)] [Also in Group XXXIV] In an hydraulic clutch, the rise in pressure of the operating liquid consequent on rendering the clutch effective to transmit power, releases a brake on the driven member. The clutch comprises a, rotor c on the driving member carrying pivoted vanes s engaging the eccentric bore of a casing e secured to the driven member. Operating liquid enters the clutch from a reservoir b through a port 2 and returns through ports 3, 4 in the driving shaft controlled by a valve v. The clutch casing also carries plates 5 supporting brake shoes 7, normally held in contact with a stationary housing 8 by springs 32. When the valve v is moved to cover ports 3 and cut off return flow of liquid from the clutch, the vanes s are urged into contact with the casing e and drive is transmitted. Simultaneously, the pressure in the clutch acts through pipes 19 on pistons 27 to compress the springs 32 and release the brake.

An alkaline primary cell comprises an anode strip 10 of metal foil such as zinc, wound into a roll 11 with a strip of porous sheet material 12 such as alkaline resistant paper, the anode foil being corrugated, possibly at a rate of 40 to the inch, or otherwise deformed to a peak to peak distance of 3-4 times the foil thickness, in order to provide space between adjacent roll turns for solid anode metal reactive products such as zinc oxide formed during cell operation. The foil 10 and paper 12 are mutually displaced so that the foil projects at one roll end and the paper at the other. The electrode roll is covered by a sleeve 14 of alkaline resistant plastic, the zinc amalgamated and the paper impregnated with an aqueous alkaline electrolyte such as 1.5-2.5% ZnO, 32-36% KOH 61.5/- 66.5% H 2 O.

Abstract: 546,120. Road sweeping machines. LEWIN, W. J., and LEWIN ROAD SWEEPERS, Ltd. Dec. 22, 1940, No. 18007. [Class 107] In a road sweeping machine, two or more rotary brush units inclined to one another are arranged end to end on a single straight driving shaft extending through the units, means being provided to adjust the axis of at least one inclined brush unit round the axis of the driving shaft and to secure such unit or units in adjusted position. In the form shown, the brushassembly comprises a central unit 11 and forwardly inclined intermeshing side units 12, 13 all three units being driven by a single straight shaft 10 passing through the units. The outer ends of the units 12, 13 are supported on bearings 23 arranged eccentrically to the bearings 26 of the driving shaft 10. This shaft is of square section and engages the inner ends of the units 12, 13 by driving teeth 19, 20 arranged on ball jointed parts 17, 16. The shaft 10 is in direct driving engagement with the central unit 11. The bearings 23 are movable round the bearings 26 to permit of adjusting the axis of each inclined brush round the shaft axis in a conical path and securing the parts in the adjusted position. This enables the forward inclination of the inclined brushes to be varied and provides a downward inclination to suit the road camber.

A pulverulent product to be classified according to its grain size is introduced in suspension in carrier air into a curved conduit 2 via a tube 4 which has a cross-section smaller than that of the inlet end of the conduit and which is connected to the latter near its inner wall 5. Separating air is introduced into the conduit via a tube 6. The outlet end of the conduit is divided by a longitudinal partition 21 into inner and outer ducts or channels communicating with tubes 8 and 10 for the discharge of small and large particles respectively. The tubes 8, 10 communicate with cyclones 12, 13 in which the air is separated from the particles and extracted via a common pipe 16 by a suction fan 18. Throttling members 7 and 20 regulate the flow rate of the separating air and of the air in the tubes 8, 10 respectively. The length of penetration and the radial position of the particle are adjustable, the cross-sections of the tubes 8, 10 being modified when those of the ducts formed by the partition are modified. The product may be introduced together with the carrier air into the tube 4 or the product may be introduced at C and the carrier air at A. One or each of the tubes 8, 10, instead of being connected to a cyclone as shown, may be connected to another separator assembly for further separation or classification of the particles. The tubes 4, 6 and the duct 2 may not be rectangular in cross-section.

The stem 5 which has a flattened portion (14), Fig. 3 (not shown) to assist withdrawal of air passes through a stuffing box 9 and is axially adjustable to enable different dose volumes to be selected. The air pump 20 comprises a flexible tube 24 connected to a mercury reservoir (not shown), which moves together with a slide 21 under the action of a counterweight 22. During downward movement of the slide 21 a spring-loaded switching tongue 27 causes a mechanism 19 to pivot to bring a mercury storage container 18 under the capillary tube and creates a vacuum in the line 12 so drawing mercury into the tube 11. Upward movement of the slide 21 causes a momentary pressure increase in the line 12 to discharge a droplet of mercury.

Serrated feed wheels 4 are driven by a sprocket 46 and are geared to one or more of the rolls being driven in a direction to assist the feed. A number of feeler rolls extend transversely to the direction of feed. The two outer of the upper feeler gauge rolls 5 are mounted on independent rocking levers, and the two centre rolls are carried by a third lever which operates ball-ended rods to move the floating lever 44 in accordance with the minimum thickness. The workpiece is fed by a conveyer to a stamping device and splitting rolls 6, 8. After splitting the gate 1 is raised by a cam 10 through a rod 33.
