Title: Improvements in and relating to steering systems for vehicles
IPC: B61F9/00
Filed: 1960-10-06
Abstract: 940,782. Steering vehicles. R. MAESTRELLI. Oct. 6, 1960 [Nov. 7, 1959; April 14, 1960], No. 34283/60. Heading B7H. [Also in Division E1] A steering system for a vehicle having pneumatic tyre covered wheels comprises tracks for the wheel and a guide rail associated with each track for co-operation with guide wheels for steering the vehicle, there being provided, in the vicinity of change-over points, additional guide rails which cooperate with additional guide rollers or wheels to guide the vehicle. As shown in Figs. 1 and 3, the vehicle wheels 2 run on tracks 1 and are steered through a linkage from members 7 which carry guide rollers 8 which co-operate with the inner surface 9a of a guide rail 9. In the vicinity of points, an additional guide rail 9b is provided which cooperates with guide rollers 10 mounted on the members 7, the rollers 8 and 10 co-operating to guide the vehicle past the points. Change over sections 12, 12a, 13, 13a pivoted at 14, 14a, 15, 15a are provided at the points to facilitate the vehicle passing the points in either direction. If a vehicle is proceeding in a direction V against an adverse setting of the sections as shown in Fig. 3, the guide rollers 10 co-operate with the guide rails 9b to restore the sections to the in line position, the sections being interconnected by cross-members, not shown, for parallel movement, and the action may be servo-assisted. In an alternative arrangement, the wheels are steered from rollers 19 cooperating with rails 18, the wheel 8 not making contact with the rails 9 except in cases of extreme movement, e.g. under centrifugal force, and at the points. As shown in Fig. 2, the rails 9 are rubber faced to provide the guide surface 9a and the arms 7 are telescopic and spring loaded to allow for some lateral movement. In a modification, Figs. 5 and 6, guide rollers 31 and 32 and additional rollers 37, 38 are mounted on supports 24, 24a which are pivoted at 23, 23a and connected together by a bar 27 of adjustable length. The rollers 31 and 32 co-operate with rails 21, 21a for guiding the vehicle and the rollers 37 and 38 co-operate with rails 35 and 36 for guiding the vehicle over the points and for restoring the position of pivoted guide rail sections 33, 34 if adversely placed. As shown in Figs. 7, 8 and 9, guide rollers 41 co-operate with tracks 21 and 21a, while rollers 42 are provided for co-operation with guide sections 45, 45a at cross over points and located above the rails 21. Should a vehicle be travelling in the direction of arrow f8, Fig. 7, and the points are adversely set, the leading rollers 42 will restore the positions of the pivoted sections 45, 45a. Rails 5 (Fig. 1) may be provided for flanged wheel vehicles.

Abstract: 1303920 Pipe couplings GRINNEL CORP 22 July 1971 [24 July 1970] 34441/71 Heading F2G [Also in Division A5] An adjustable drop nipple for connecting a pendent fire sprinkler 15 to a distribution system comprises outer first pipe 20 threaded at end 21 for connection to the system, inner second pipe 36 telescoped at one end into end 22 of pipe 20 and threaded at the other for connection to 15, and restraining means adjacent the telescoped pipe connection automatically resisting downward movement of 36 in the axial direction and including means for releasing pipe 36 for upward axial movement in response to an upward force on 36. The restraining and adjusting means may be provided by (Fig. 1) reducer assembly 24 enclosing externally threaded rollers 46. Reducer fitting 26 has annular curved inner surface 41 converging inwardly from the larger (upper) opening to the smaller (lower) opening 29, and is formed with annular groove 28 in the surface of 29. Inside reducer 26, pipe 36 telescopes into end 22 of pipe 20, the outer surface of 36 slightly spaced from the edge of opening 29 and 0-ring 38 in groove 28 providing a fluid seal between 29 and 36. Bushing 37, having external recesses 39 for fluid passage, prevents complete withdrawal of 36 from 20. Annular cavity 40 of downwardly reducing size is formed between pipe 36 and surface 41 and contains tapered threaded rollers 46 (Fig. 7) of length and diameter such that they can move between a jammed position gripping 36 and 41, and a free position in the wider part of 40. Tubular plastic retainer 45 has its lower edge resting against surface 41, outer surface 49 of its upper rim 48 engaging the upper opening of 26 and inner surface 50 round pipe 36, and is formed with axially extending slots 52 which accommodate rollers 46 and allow them to ride upwardly in cavity 40. In the normal pendent position of sprinkler 15 and nipple 10, rollers 46 rest at the foot of slots 52, gripping pipe 36 and surface 41 and restraining downward movement of 36. If a force is applied upwardly against 36, rollers 46 move up slots 52 and release their grip on 36, freeing the pipe for upward adjustment of the nipple in its installed position. To lower the installed nipple pipe 36 is rotated in the direction of roller threads 60 and moves spirally downward thereon to the required position. In the Figs. 4, 5 modification reducer fitting 80 with recesses 82 eliminates the need for separate retainer 45 and in the Fig. 6 modification the 0-ring 38 of Fig. 1 is eliminated, and a fluid-tight seal is provided by 0-ring 92 in annular groove 91 of bushing 90, in a position above reducer fitting 94.

Abstract: 433,038. Screw sockets. HAMILL, W. W., Beechcroft, Four Oaks Road, Four Oaks, Warwickshire. Dec. 8, 1933, Nos. 34529/33, 15588/34, and 28629 /34. [Class 89 (i)] Relates to arrangements for attaching objects to walls or in which a bolt to which the object is secured is surrounded by an expansible member which by axial compression is caused to expand peripherally to grip a cavity in the wall &c. According to the invention rubber or other material having like characteristics is employed as the elastic member. The bolt 53, Fig. 1, provided with the wedge-shaped end abutment 9 is surrounded by the rubber sleeve 3 which is axially compressed by axial displacement of the splined wedge to cause the rubber to grip the wall of the cavity. The resulting pressure on the walls of the cavity may be localized or varied by a variation of the shape of the abutment faces of the wedges and rubber sleeve or by arranging rubber rings of varying degrees of hardness on the bolt. Arrangements may also be made for reducing friction between the wedge and the actuating-nut by suitably shaping the abutting faces. In another form the rubber member 39, Fig. 13, is contained in a metal cage 32 and is expanded by the wedge 20 operated by the screw 41. The whole device may be embedded in rubber for insulating purposes. The rubber sleeve may have a non- circular periphery and may have a corrugated or otherwise roughened exterior.

Filed: 1976-08-27
Abstract: 1505478 Brake boosters MIDLAND-ROSS CORP 27 Aug 1976 [26 Sept 1975] 35773/76 Heading F2F  A brake booster has an hydraulic servo and a vacuum servo, the former being brought into operation first. The booster has an input rod 60 connected to a member 64 with an extension 64 which abuts a piston-rod 128, which in turn abuts the end 118 of a hollow sleeve G sliding in an hydraulic piston G, which in turn engages the output rod 12. Hydraulic servo assistance is provided by hydraulic fluid from inlet port 148 bearing on the end face 160 of piston G. Feedback is provided by the sleeve G moving clear of the end face 126 of the piston-rod 128 to allow hydraulic fluid to pass through the centre of the sleeve G and to outlet port 146 via passages 156. The sleeve G is biased towards the piston-rod 128 and towards a stop 106 by a spring 108 and by hydraulic pressure acting on differential areas of the sleeve. Vacuum servo assistance is provided by admitting atmospheric air into a space 34 to the right of a diaphragm 22, via valve member 68 and passage 58. When the valve member 68 is in its rightward position as shown, the space 34 communicates with the evacuated space 32 via passages and spaces 58, 56, 54, 52, 50. The end float of the piston-rod 128, and the clearance 140 between the hydraulic piston F and the inlet port 148 are preferably such that on initial movement of the input rod 60 the vacuum booster is operated momentarily to pressurize the chamber 34 sufficiently to cause the diaphragm 22 to move across the space 32 when the hydraulic booster is operated. The source of hydraulic power is an hydraulic pump which also provides power-assisted steering. The output rod 12 leads to a dual master cylinder supplying front and rear wheels separately, the rear wheels via a modulating valve responsive to skid signals.
