Abstract: 764,624. Door-operating apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 15,1954 [Dec. 21,1953], No. 36296/54. Class 65 (1). [Also in Group XXXVII] An object-detecting element yieldably mounted on the edge' of a door is retracted before the end of the closing movement; it may remain retracted during opening. The complete object-detecting device.is preferably detachable from the door as a unit; if more than one door is provided for an opening, each door carries such a device. In the case of a lift, it is preferably associated with the cage door, and placed between the latter and the shaft door. In the arrangement shown, a nosing 107, which may be of a plastic or of flexible material such as rubber on a rigid support member, movably embraces the edge of the door 5 and is mounted thereon by a pair of links 109 and bellcrank levers 49 pivotally carried by brackets 43 on a base-plate 47, the cranks being connected by a link 53 movable between adjustable stops and biased upwardly by a spring 55 so as to project' 'the nosing 107; a dashpot may be provided to cushion movement of the nosing. The links 109 have extensions 109a which move between adjustable stops and actuate the necessary switch 113 to stop or reverse the door motor when the closing of the door is obstructed. The nosing 107 is retracted at the end of the closing movement of the door by a fixed cam rotating a lever 65 on the door clockwise to pull down the link 53 by a cable 61 and to allow a spring latch 69 to engage a lug on the link. At the start of the opening movement the lever 65 is freed from the cam and the spring 55 restores it and the nosing 107, a spring 71 being slightly stressed so that when a second fixed cam rotates the lever 65 anti-clockwise at the end of the opening movement, to take the weight of the nosing on the cable 61, the latch is released and the nosing can move forward when the door starts to close. In a modification the nosing is held retracted by an electromagnet. The object-detecting device may be of the kind utilizing an electric field extending ahead of the detecting element. The door motor is controlled by opening and closing relays which are energized alternatively according to the position of a control switch, the circuits including contacts of a relay which is normally energized through the switch or switches 113 of the detector or detectors. Specifications 652,461 and 658,712 are referred to.

Title: A method and means for press-forming articles
Inventor: SCOTT THOMAS WILLIAM LONSDALE
IPC: B21D22/26
Filed: 1957-02-04
Abstract: 837,105. Shaping cup-like articles. ROSE VALE MANUFACTURING CO. Ltd. Feb. 28, 1958 [Feb. 4, 1957], No. 36363/56. Class 100(2) Articles such as cups, confection holders and milk bottle caps requiring different depths of draw are formed from soft material, e.g. aluminium foil, in a single press of constant stroke wherein a plurality of die sets is arranged to work on the same sheet of material, each set being for a different size of article, and as each smaller article is completed the die parts therefor yield to allow the completion of the next larger article during the same stroke of the press. Each die set comprises a male part including a tubular member 1, carrying a blanking tool 7, and a male former 4 both secured to the movable head 3 of the press, a collar 5 being slidable between the parts 1 and 4 and biased downwards by a spring 6. The female part of each die set includes an annular member 8 mounted on the fixed head 10 of the press, a resiliently mounted female former 11 concentric therewith and biased upwards by a spring 12, and an ejector 15 biased upwards by a spring 16. In the die set for forming the largest article the spring 12 may be omitted and the former 11 may be fixedly mounted. A strip of foil x is fed intermittently between the die parts. As the press closes the tool 7 cuts out a blank in co-operation with the annular member 8, the blank is gripped between the collar 5 and the face 11b of the female former 11, and the male former 4 draws the blank into the female former, forcing back the ejector 15 as it does so. The strength of the spring 12 is such as not to yield under the pressures necessary for carrying out the forming operation but to yield if the male die part continues to move downward after the forming operation is complete. Thus as each of the smaller articles is completely formed its female former 11 is in turn depressed against its spring 12 as the head 3 continues to move downwards until the largest article has been formed. The head 3 is then raised and stripper rings 17 push the waste foil off the tools 7, the finished articles being ejected on to a shoot by the ejectors 15. In modifications the male former 4 may be resiliently mounted as well as or instead of the female former 11. Also the positions of the male and female formers may be reversed, the latter being mounted on the head 3 within the tubular member 1.

Abstract: 1,020,241. Fifth-wheel couplings. PEER CARTAGE CO. Inc. Sept. 25, 1962 [Sept. 25, 1961], No. 36379/62. Heading B7T. A king pin 12 on a trailer which may be coupled to a fifth wheel tractor plate 224 in the usual way is provided with a pair of service fluid flow passages 124, 126 and electric cable passages 104, the flow passages and electric cables being automatically connectible to a vertically movable insert member or socket 14 on the tractor, which member is also provided with flow passages 182, 204, cable connector 170 and cable passages 172, the arrangement being such that after the pin 12 has been coupled to the tractor a cover plate is first removed from the member 14 and then a piston and cylinder 60 is operated to move a ball headed rod 238 upwardly and engage together the members 14 and 12 with their service lines and cables. In Fig. 1 (not shown) pressure fluid from a line 46 connects with a cover plate control piston and cylinder 48 and a control valve 54. The valve will not operate until the piston 48 has removed the cover plate from the insert member 14, and then fluid passes to a T-member 58 on the insert piston 60. When the piston 60 operates and the insert member 14 is engaged with the pin 12 a delay valve 64 operates to allow fluid to flow through the line 66 and thence to the line 68. The connection between the lines 34 and 38 is also made. To disconnect the members 12 and 14 a valve 74 in the tractor cab is operated and fluid flows through line 78 into the piston 60 to force the member 14 downwardly. At the same time fluid flows into a piston and cylinder 88 which retracts the king pin lock, and a valve 92 operates when the lock is released to permit fluid to flow into the piston 48 and move the cover plate back over the member 14. The cables in the pin 12 are connected to electrical contacts 102 mounted in a nylon ring 100, and the cables in the member 14 are connected to sprung electrical contacts 166 mounted in a nylon block 160. The flow passages 204 and 126 are connected via a conical sealing member 214 provided with passages 218, 226, and the passages 182, 124 are connected via a spider 210 mounting the sealing member 214 and provided with peripheral passages 212. The member 14 is resiliently supported by a plurality of U-springs 242 and may be readily removed by disconnecting the flexible lines and connectors 36, 50 and 82.
