Abstract: 268,622. Richter, J. A. Aug. 4, 1926. Cotters.-A machine for making tapered pins or for producing cylindrical enlargements on cylindrical blanks comprises a number of grooving tools which are pressed radially into an axially moving blank to cause an outward flow of metal, the radial movement being variable according to the degree and direction of the taper required. The bed 10 of a press carries a base 11 formed with a tool-holder 12 which is bored centrally at 14 and has a number of radial grooves 15. Sliding members 18 fitted in the radial grooves carry hardened steel discs 16 and may be forced radially inwards towards the blank 45 by means of levers 24 which are pivoted at 25 to lugs on the holder, outward movement of the levers being limited by adjustable abutment screws 29. The upper ends of the levers carry rollers 48 engaging adjustable cam strips 39 which are fitted in recesses in a clamping-ring 37 secured to the press-head. The head carries a central feed member 44 and on the descent of the press-head the blank is forced through a guide 30 while the tools are fed gradually inwards by the cams 39 to produce radial grooves of gradually increasing depth in the blank. The levers are returned by spring plungers 21 and the finished workpiece, having the form shown in Fig. 10, passes through the central bore 14. In a modification, Fig. 3, the levers are pivoted at 56 above the tools and the cams have outwardly disposed surfaces 59. In another modification, the cams have curved surfaces which produce a pin shaped as shown in Fig. 7. By further modification of the cam surfaces, other forms of pins may be produced. In another modification, Fig. 11, for producing cylindrical enlargements 161 on a blank 146, by forming grooves 160, Fig. 14, the grooving-tools are mounted on shafts 117 carried in bearing-plates 118 in radial openings 115 of the column 112. Rollers 121 are also mounted on the shafts 117 and the blank passes through a central guide 123. The head comprises a member 125 fitted with a number of tool-actuating slides 129 which can move on spherical seatings 130 in pivot bushings 132. The lower ends of the cam slides are adjustably secured to a ring 138, adjustment being effected by wedges 141. Each cam slide carries two cams 150 supported by pins 152 and having one or more operative surfaces 153. On descent of the head, an adjustable pin 145 feeds the work past the tools and the surfaces 153 coact with the rollers 121 to press the tools against the work. In a further modification, Fig. 16, the disc tools are replaced by straight-edged tools 170 and the blank 175 is supported on an abutment 176. This form of machine produces an enlargement 184, Fig. 18, having sharp corners. By lowering the abut. ment 176 more than one such enlargement may be formed on the same shaft.

Title: Hydraulic control valve assemblies
IPC: B60T13/14
Filed: 1973-04-24
Abstract: 1423719 Valves GIRLING Ltd 27 March 1974 [24 April 1973] 19458/73 Heading F2V In a brake control valve having an inlet valve 24 controlling communication between an inlet port 19, for connection to a pump or accumulator, and a port 22, for connection to the brakes, and also an exhaust valve 32 for controlling communication between the brake port 22 and an outlet port 16 for connection to a reservoir, a mechanism is included so that positive movement of an operating piston 5 results in positive movement of the inlet valve in the opposite direction to that of the piston. The piston 5 may be moved directly by a foot pedal or through an intermediate member providing feel. Alternatively, the piston could be moved by hydraulic pressure from a master cylinder or from a fluid control valve of similar construction to the valve of the invention. The inlet valve 24 has an enlarged head 27 and a conical end 25 which normally engages a seat 26 formed in a plug member 9 screwed into a housing 1. The plug has a forward extension 10 and a rubber block 29 is located between the end face of this extension and the enlarged head 27 of the inlet valve. The exhaust valve 32 has an enlarged head 31 and a conical end 33 which coacts with a seat 34 in the piston. The head 31 abuts against the closed end 30 of a sleeve 28 the open end of which abuts the rubber block 29. An annular abutment member 40 surrounds the enlarged head of the exhaust valve and a counter-bored recess in it engages the enlarged head. Projections 42 on the member 40 pass through apertures in the end of the sleeve 28 and engage the enlarged head 27 of the inlet valve. A helical spring 39 is located between the abutment member 40 and the piston 5.  When the piston 5 is moved to the left the exhaust valve is first closed and the valve member 32 then acts as a thrust member on the end of the sleeve 28. The annular face of the sleeve compresses the rubber block 29 around its periphery and this deforms to cause the central portion surrounding the valve stem to move to the right carrying the head 27 of the inlet valve with it thus opening the valve, the spring 39 acting through the abutment member and the projections thereon providing a loading bias to prevent deformation of the block before the exhaust valve is closed. In an alternative embodiment, Fig. 2 (not shown), the abutment member 40 is replaced by a fixed abutment plate (44) against which the spring 39 bears to provide a return force for the piston. A further helical spring (43) located between the inlet valve head 27 and the end wall of the sleeve 28 provides the necessary bias for the inlet valve.
