Title: Improved apparatus for operating the brakes of railway and other vehicles and for other purposes
IPC: B61H13/04
Filed: 1919-07-30
Abstract: 155,868. Tinson, W. H. (Saccaggio, P. C.). July 30, 1919. Force - transmitting mechanism. - In hand or power operated braking apparatus for railway and other vehicles, applicable also for other purposes of the kind in which the slack of the rigging is taken up and the blocks, &c. brought up to the wheel-treads, &c. under a relativelv small leverage, the increased tension in the pull-rod then overcoming a spring and automatically increasing the leverage to give a heavy pressure of the blocks on the wheel-treads, the power is transmitted during the initial movement through a spring-stressed friction-clutch device the parts of which are disengaged when the tension in the pull-rod increases. Cam. eccentric or toothed-gearing means operating on a lever connected to the pull-rod, are employed to increase the leverage. In the form shown in Fig. 2 the hand-lever L turns the cham 1 on the rock-shaft S and the lever 5 at first turns in one with the cam being bound thereto by a cranked lever 9 connected to the pull-rod P at P<1> and to the lever 5 at 8 and engaging the cam by a projection 10 held in an inclined recess 11 by an adjustable spring 12. The lever 5 at the lower end is supported by a hanging arm 6 which carries also a spring-pressed pawl 15. On the tension in the pull-rod increasing, the cam-plate forces the projection 10 out of the recess 11 and carries a projection 18 away from a rod 19 controlling the pawl 15, thus allowing the latter to engage a rack 17 and fixing the point 7 as a fulcrum on which further movement of the lever 5 takes place under the action of the cam-slot 2 on the roller 3 mounted on the lever 5. In a modification, the springs 12, 16 are arranged as compression springs, and the rack 17 is formed on a pivoted arm supported by a roller on an extension of the lever 5. In a further modification, the arm 8, P<1> of the cranked lever 9 is dispensed with and the lever 5 directly connected to the pull-rod. In a further modification, an eccentric on the shaft S acts on a roller mounted in ball bearings on the lever 5, the lever 9 is formed with three arms, one of which acts as a stop for the pawl, and a single spring connects and controls the three-armed lever and the pawl. In a further modification, Fig. 17, suitable for power brakes, the power-lever L turns a disc 44 on the shaft S and at first operates the pull-rod P by the cranked lever 9 the projection 10 on which is held in engagement with the recess 11 on the disc 44 by the adjustable spring 12. With further tension in the pull-rod, the projection 10 leaves the recess 11 and a pawl 47 on the disc 44 engages and turns a ratchet wheel 46 to which is attached a pinion 45 thus rotating a larger pinion 49 mounted on a lever 48 rocking about the shaft S and connected to the cranked lever 9 at 54. The pinion 49 travels along a rack 50 applying the increased pressure to the pull-rod through the levers 48, 9.

Title: Improvements in or relating to friction drive speed regulators
IPC: F16H13/14
Filed: 1955-06-30
Abstract: 789,023. Variabie-speed gear. SOC. DES FABRICATIONS UNICUM. June 30, 1955 [July 22, 1954; May 4, 1955], No. 18944/55. Class 80 (2). Relates to a friction gear, particularly of the type in which a driving disc 4 engages rollers 5 movable laterally by a screw 6 across the face of the driving disc to vary the velocity ratio and engaging in turn a disc 7 rotating with and axially slidable upon a hollow driven shaft 8. The invention comprises means for automatically increasing the force frictionally engaging the driven disc 7 and the rollers 5 in response to increasing torque. A sleeve 13 is axially slidable on a key 14 within the driven shaft 81 and is biased to the right of Fig. 2 by a compressed spring 15. A spindle 16 within the sleeve 13 has an enlarged end which abuts a shoulder on the sleeve and is formed with a concave recess 16<SP>3</SP> for a complementarily shaped surface on a plate 20 thus rockably supported. The other side of the plate 20 is formed with projections 20<SP>2</SP> having convex heads engaged by complementary surfaces 23<SP>2</SP> on camming members 23 having the general shape of sectors of a sphere. Convex surfaces 23<SP>1</SP> on the camming members 23 lie in pockets 221 in a disc 22 fast with the driven friction disc 7, which is rotatably supported on the shaft 8 by needle bearings 12. The pockets 22<SP>1</SP> are each formed according to three radii of curvature: (1) a radius of curvature R, Fig. 3, the pockets lying along the line traced out in a plane perpendicular to the main axis by this radius; (2) a radius of curvature R, Fig. 4, moving along the section line 4-4 of Fig. 3; and (3) a radius of curvature R<SP>2</SP>, Fig. 5, in the radial plane. The radius of curvature R<SP>2</SP> is the same as the radius of curvature of the convex surface 23<SP>1</SP> on the camming members 23. Spigots 24 in the disc 22 have rounded ends engaging holes 23<SP>3</SP> in the camming members to retain them in position while allowing rolling of the surfaces 23<SP>1</SP> on the surfaces 22<SP>1</SP>. The end 16<SP>2</SP> of the spindle 16 is of convex shape and is engaged by a complementary surface in the end of a screw 17 connected to a spring 18 torsioned by turning a screw 19 secured to its other end. The torsion of the spring 18 turns the screw 17 so that any wear in the parts is automatically taken up. Lubricant can be introduced through a conduit 25. Initial friction engagement of the driven disc 7 and rollers 5 is caused by the spring 15 biasing the sleeve 16 &c. to the right. With increasing torque, the disc 7 turns slightly on the needle rollers 12 relatively to the driven shaft 8, and tilts the camming members 23 to force the discs 22, 7 to the right and engage the disc 7 and rollers 5 more firmly. In a modification, Figs. 12-19 (not shown), the sector-shaped camming members 23 are replaced by balls. Reference has been directed by the Comptroller to Specification 650,166.

Title: Rubber mixer
IPC: B29B7/26
Filed: 1958-06-16
Abstract: 838,475. Rubber-mixing machines; discharging doors. FARREL-BIRMINGHAM CO. Inc. June 16, 1958 [Jan. 21, 1958], No. 19155/58. Addition to 774,651. Class 86 The rubber mixer described in the parent Specification has the discharge opening of the mixing chamber 20 closed by a door 23 yieldingly mounted for movement relative to its support 24. To control the movement, springs are now introduced between the abutting faces of the door and its support. The springs 34, Figs. 2 and 3, may be placed between an upstanding rib 33 on the support and downwardly extending flanges of the door, so that the springs hold the door centrally of its support while allowing relative movement during opening and closing of the chamber 20. Strips 41 of low friction material such as nylon may be placed between the door and the support. In an alternative arrangement, Fig. 4, elongated leaf springs 43 of corrugated form are placed in opposed grooves 42 extending along the abutting faces of the door and its support, so that each spring bears at points along its length against the door and against the support and so stresses the two members in opposing directions. The springs and the connecting bolts 37 allow a slight pivotal movement of the door relatively to its support in the plane of the abutting surfaces. Helical springs housed in individual sockets may replace the leaf springs. By tightening the springs 39 on the bolts 37, the helical springs can be stressed as needed. In Fig. 10, the door and its support are hinged together by a pivot pin 55 extending through interlocking knuckles and the springs are placed in recesses 58 in the door 23 and surround the bolts 57. Alternatively the recesses may be in the support and the stressing springs are then omitted from the outer ends of the bolts together with the pivotal connection of the door and support.

Abstract: 702,390. Making turbines and compressors; welding by pressure. ROLLS-ROYCE,'Ltd. July 19, 1951 [Aug. 1, 1950], No. 19182/50. Classes 83 (2) and 83 (4). [Also in Group XXVI] In manufacturing turbo machines &c. one part to be pressure butt resistance welded is formed with tapered grooving to produce a series of spaced lands, several of which are contacted by the other part during welding to provide an initial reduced contact area which increases as the other part penetrates the lands against increasing resistance. The sides of the grooving are preferably inclined at about 55 degrees to one another. In an embodiment, a turbine rotor disc 10, Fig. 3; is provided with circumferential V grooves 13 by turning, milling, knurling, punching &c. to leave spaced lands having surfaces 12l-i. These surfaces vary in width with the thickness of the section of the blade which is preferably solid but may be hollow and which is to be welded thereto. The land surfaces may all have the same width. The grooves 13 may be separate and circumferentially continuous or a continuous thread like groove may be provided. The lands may extend only over the rotor disc surface only where each blade is to be attached. Where the grooves are continuous a tubular shroud 14, Fig. 6 having slots 16 for the blades is tack welded at 15 to the lands 12, before the blades are welded, to provide a smooth rotor surface. In a modification a tubular shroud 17, Fig. 7, having slots for the blades is welded to an annular disc 18 which is welded to the disc 10 before the blades 11 are welded. Another disc 19 is then welded in position and tack welds as at 20 may secure the shroud 17 to the blades. Air holes 21 are provided to allow cooling of the roots of the blades. To insulate the blades from the shrouds during welding, thin mica or vitreous enamel is introduced between the blades and the edges of the slots. To weld a blade to a rotor disc, the latter is mounted on a fixed table and the blade in contact blocks is pressed into engagement therewith by means of a pneumatic ram. Pressure sufficient to forge the weld is exerted. A small A.C. e.m.f. of 3 volts is applied across the abutting surfaces for say <SP>1</SP>/ 5  second when the blade end and lands fuse and move together for a limited distance.
