Title: Improvements in and relating to hydraulic rotary blade apparatus adapted to operate as pump or as a motor
IPC: F04C2/344
Filed: 1946-11-12
Abstract: 630,260. Rotary engines or pumps. NICOLAS, J. J. Nov. 12, 1946, Nos. 33659 and 33660. Convention dates, Nov. 12, 1945, and Oct. 29,1946. [Class 110(ii)] A hydraulic apparatus having sliding vanes has an annular chamber comprising two co-axial cylindrical walls, and two end walls respectively rigid with each cylindrical wall so that each pair of connected walls may rotate relatively, abutments extending across the annular chamber to divide it up, the blades and abutments being connected respectively to the above pairs of walls. Axial thrust due to working fluid within the annular chamber is balanced by a fluid cushion between balancing walls transverse to the common axis of the cylindrical walls and fast with the latter, respectively. Figs. 1 and 2 show a chamber formed between walls 1, 2, radial abutments 6, 7, and sliding vanes 13 in slots 11, the vanes being guided by bearings 15 in grooves 16. A chamber 12 communicates by means of a channel 17 with the tip of a vane 13 but each inner edge m-n of a vane is wider than the tip p-q so that the vane is forced outwards. Fluid is admitted through a port 9 and exhausted through a port 10, grooves 19 allowing some working fluid to short-circuit the tip of a vane. Alternative inlet and exhaust ports 22, 21 may be used. In another apparatus, Figs. 3, 4, axially-sliding vanes 32 are moved by a cam 33. The cam is secured to two diametrically-opposed abutments 34 which may slide axially in the stator 26 through pressure fluid admitted into a cylinder 35 having a piston 36. The fluid may be obtained from a working chamber 25. The abutments are pressed against the rotor 27 whatever the position of the latter, by the thrust produced at the bottom of the cylinder 35. A space 37, between a casing end wall and the rotor 27, other than that facing the cam 33, is connected through a channel 38 with a circular groove 39. Delivery, or suction, fluid may pass through the channel 38, depending on the position of a slide-valve 41 which has openings 43, 44, connected respectively with the delivery or suction sides of the apparatus. The liquid in chamber 37 forms a cushion to balance the axial thrust on the rotor from the fluid pressure in the chamber 25. In place of the slide valve 41, a rotary valve having circular holes of different sizes, may be used. The vanes may also be moved by means of rollers riding in a cam-shaped groove.

Title: Improvements in and relating to apparatus for feeding and distributing sludgy materials
IPC: B05B17/00
Filed: 1937-12-07
Abstract: 507,012. Coating surfaces and webs; lost-motion coupling. BAKELITE, Ltd. Dec. 7, 1937, No. 33898. Convention date, Dec. 9, 1936. [Class 95] [Also in Groups VIII and XXIV] An apparatus for feeding and distributing sludgy material on to surfaces, e.g. for applying hydraulic cement to shingle tiles as in Specification 423,694, [Group X], comprises a hopper, a discharge roller forming part of the supporting surface for the material in the hopper and which carries the material from the hopper, a device for controlling the quantity of material carried from the hopper by the discharge roller and for trowelling the material while on that roller, and a bristle device for removing the trowelled material from the surface of the discharge roller and directing it by centrifugal action on to the surface to be coated. In the example the articles to be coated pass on a moving band 26 under two identical coating units. Each unit consists of a hopper 32 containing the sludgy composition, adjustable false ends 118 serving to restrict the effective size of the hopper if desired. The base of the hopper is formed of a discharge roller 50 consisting of hubs 52 and a tubular shell 54 bearing helical grooves 56. An adjustable rubber-surfaced gate roller 58 controls the rate of discharge of the composition and is driven by a chain from a sprocket 82 on the discharge roller, which in turn is driven by a motor 72 through reduction gearing 75 and a chain 74. The peripheral speed of the gate roller is less than that of the discharge roller so as to exert a wiping or trowelling action on the composition in the grooves of the discharge roller. The composition is removed from the discharge roller and thrown on to the surface to be coated by a rotary brush 108, preferably having cadmium-plated steel bristles. To prevent jamming when a large particle of composition is caught in the nip of the rollers, the gate roller drive is effected through a clutch which permits the gate roller to be driven by friction from the discharge roller for a limited fraction of a revolution. The gate roller 58 is fixed on a shaft 92 on which is mounted the driving sprocket 84 held in position by a collar 93. Two projections 94 on the sprocket co-operate with equivalent projections 100, provided with adjusting screws 102, on a clutch member 96 in the form of a hand wheel splined to the shaft by a key 98 which permits axial movement. The clutch member 96 is held in the driving position by a spring 104, a set screw 106 enabling the clutch to be held rigidly in or put of position as desired. When a large particle is caught in the nip of the rollers, the surface speed of the gate roller accelerates to that of the discharge roller, the pins 100 moving ahead of the driving pins 94. If this limited movement is insufficient to pass the particle, the operator disconnects the drive temporarily by pulling the hand wheel 96 axially, and if necessary gives the gate roller an oscillatory movement to discharge the particle.

[Class 83 (iii)] A chuck of the kind in which a number of jaws may be moved towards and away from one another by transmission operated externally of the chuck comprises a compartment 21, Fig. 1, formed in the chuck body 10 and filled with an incompressible distortable substance 23 or liquid substance, a number of plungers so mounted as to be movable into and out of the compartment, means operable externally of the chuck for applying movement to one or more of the plungers, and means for transmitting the resultant movement of the other plunger or plungers to the chuck jaws 17 in a gripping direction. The substance employed may be natural or synthetic rubber preformed to the shape of the compartment or moulded and vulcanized in situ. The jaws 17 are bonded to a plate 19 by rubber portions 20 and are brought into engagement with the tool by rotating a member 13 in threaded engagement with the body which is provided with a bore 11 to receive the machine spindle. Gripping pressure is applied through a large diameter plunger 15 when a threaded plug 25 is rotated to stress the substance 23. In another embodiment plungers 41, Fig. 4, displaced by a member 42 in threaded engagement with the body are used to apply pressure to the substance 23 and a plunger 16 in contact with the jaws. Two other embodiments of the invention are described in which the tapered bore 11 for the machine spindle is replaced by a tapped hole which receives the threaded end of a spindle bearing on the small plunger in contact with the substance. To apply gripping pressure the body is rotated relatively to the machine spindle. The Provisional Specification describes also the use of an elastic envelope fitted with liquid instead of a solid rubber body. Specification 626,342 is referred to.
