Title: Improvements in or relating to slack adjusters for brakes
IPC: B61H15/00
Filed: 1955-09-08
Abstract: 773,846. Automatic slack adjuster for brakes. SVENSKAAKTIEBOLAGET BROMSREGULATOR. Sept. 8, 1955 [Sept. 13, 1954], No. 25770/55. Class 103 (1). In an automatic slack adjuster of the type disclosed in Specification 683,673 for railway brake rigging unintentional rotation of the feed nut 5 on the screw-threaded spindle 4 due to shocks and vibrations in the brake released position of the rigging is prevented by the provision of a flange in the form of a ring 7 which is loosely mounted on nut 5 and permitted limited axial movement, as governed by the radially extending shoulder 6 on nut 5 and resilient locking ring 8 mounted on nut 5; pin 10 engaging in recess 9 on the internal periphery of ring 7 to prevent rotational movement of ring on feed nut 5 but allowing axial as well as tilting movements between the ring 7 and nut 5. The radial play of the internal cylindrical surface of a ring 7 in relation to the periphery of the nut 5 is larger than the largest possible parallel displacement of the nut into an eccentric position with respect to the seat surface 3 so that displacement of the nut 5 and screwthreaded spindle 4 with respect to the axis of the seat surface 3 on non-rotatable feed sleeve 2 due to vibrations or shocks will not affect the continuous axial pressure of the seat 3, caused by a spring (not shown), against the ring 7 and will, therefore, prevent the nut 5 from turning on spindle 4.

Title: Improvements relating to apparatus for treating metal articles with abrasive
IPC: B24C3/08
Filed: 1939-09-18
Abstract: 532,647. Cleaning castings by sand-blast. AMERICAN FOUNDRY EQUIPMENT CO. Sept. 18, 1939, No. 26097. Convention date, Sept. 24, 1938. [Class 60] An abrading machine for cleaning castings, forgings &c. comprises a device A for projecting abrasive material, and a flexible support 70 for rotating the articles W which are advanced through the abrasive stream by an intermittently advancing pusher 103. The abrasive is supplied from a hopper 38 and projected by two bladed wheels A, B in streams Sa, Sb adjusted to different angles. The pusher 103 is returned by a spring or weight 108 to allow an article and preferably a spacer 150 to be introduced and is advanced by a projection 114 of a driven chain 111. The advancing articles first enter a rotating perforated drum 126 which may be separately driven or engage projections 77 on one of three driven chains 89. These carry bars 71 of or faced with non- abrasive material and are draped over driven gears 80, Fig. 4, to form inner and outer loops separated by an adjustable guide 82. The articles are then pushed by succeeding articles through the inner loop 170 by which they are rotated in the abrasive streams, then through a perforated drum 135 similar to 126 where abrasive &c. is discarded and finally through curtains 145 on to a table 144. The used abrasive is carried by screws 49 to a sump 48 whence it is raised by a conveyer 61 to screening and separating apparatus, if desired, to remove foreign material, and then to the hopper 38. In a modification the pusher is mounted so as to be freely rotatable in a chamber into which the articles &c. are introduced through a curtain. The spacer 150 shown comprises two rings 151, 153, Fig. 7, and a rectangular form 152, in three planes at right-angles, joined together, e.g. by welding, stiffened by struts and, if desired, covered with rubber &c.

Title: Driving device for hydraulic machines
IPC: F04D13/02
Filed: 1953-09-22
Abstract: 743,042. Centrifugal pumps. TOBBER, A. W. Sept. 22, 1953 [Sept. 22, 1952], No. 26144/53. Class 110(1) [Also in Group XXIX] A rotary pump for supplying liquid to operate a hydraulic machine is adapted to operate practically completely full of liquid, and storage of energy is effected in a gyrating body which rotates with the pump. The pump is of the type having a rotating chamber 1, Fig. 4, supplied with liquid through a pipe 7, the liquid being rotated by vanes 3 and withdrawn through apertures 5, Fig. 5, at each end of a stationary pipe 4 and conveyed through the pipe to a discharge pipe 8. A flywheel 2 stores up energy during the non-operative period of the cycle of operations of the load (e.g., a hydraulic press). The pipe 4 may, as shown, comprise a cental part 17 and two pivoted end parts 18. Each part 18 carries a helically toothed segment 19 which engages a correspondingly toothed rack 20. The racks 20 are carried by a hollow cylinder 21 which can move vertically and is subjected internally to the pressure at the discharge pipe 8. Vertical displacement of the cylinder 21 in response to variation of the pressure in pipe 8 caused by variations in the load causes a pivotal movement of the parts 18 to bring the apertures 5 to a radial position at which the discharge pressure matches the requirements of the load. When the pump is idling, losses are reduced by allowing the pipe 4 to rotate with the liquid. For this purpose, a brake is provided, comprising a cone 10, Fig. 3, carried by the pipe 4 and a cone 11 which is connected non-rotatably to the discharge pipe 8 but with freedom to slide axially in response to hydraulic pressure applied through a pipe 13, so as to engage the cone 10 and hold the pipe 4 stationary. A spring 12 holds the cones out of engagement when the pump is idling. The regulating pressure applied to the cylinder 21 may be derived from an external source to permit arbitrary adjustment or to render the regulation dependent on the pressure prevailing at another place in a system to which the pump is connected. The racks 20 may be led to the outside of the pump and actuated from there. Fig. 6 shows two pumps used to actuate a hydraulic press 14. Valves 15, 16 permit the pumps to be connected in parallel as at a or in series as at b.

Abstract: 270,562. Varcin, A. L. Oct. 21, 1926. Toothed gearing.-In gearing for converting reciprocating into rotary motion or vice versa by means of one or more toothed segments engaging alternately a pair of toothed racks with cam and roller members for regulating the motion at each end of the stroke, the reciprocating member is controlled by one or more cam parts on one of the moving members each cam comprising two operative surfaces to coact with a pair of rollers which are carried by the other moving member and are radially disposed relatively to the rotary member. The cam surfaces are designed to regulate the retardation and acceleration and to carry the reciprocating member on for a predetermined distance after the toothed elements have ceased to mesh. In the forms shown, the racks 1, 2 are attached directly to pistons E, E<1> reciprocating in cylinders, the arrangements being applicable to motors or pumps. In Fig. 1, a member T attached to the segmental gear P is formed with a cam ridge 10 adapted to pass between rollers G<1>, G<2> carried by a. bracket S at each end of the reciprocating member. The two end portions u, v and x, y of the cam ridge are designed to pass between the rollers as the last tooth of the segment enters or leaves the rack teeth, the median cam portion v, z, x controlling the motion whilst the teeth are out of mesh end enabling the stroke to be extended with more gradual retardation and acceleration. In Fig. 3, the racks face outwardly and mesh alternately with a pair of segmental gears P<1>, P<2> on shafts which are geared to a central shaft 0 carrying the cam members 20, 21. In this form the shaft O makes a complete revolution for each stroke. The rollers may be carried bv the rotary member in which case the cams carried by the reciprocating member are of modified shape. The rollers may engage the walls of a cam groove instead of a ridge. The device may be provided on each side of the gearing members.
