Filed: 1917-11-09
Abstract: 123,117. Holmes, J. S. Nov. 9, 1917. Paper and fibrous pipes and tubes.-In a machine for making paper &c. tubes by winding sheet material on a mandrel, a feedroller 14 is arranged on one side of the mandrel in fixed bearings, and means to guide the material over the other side of the mandrel is arranged to be swung away from the mandrel to facilitate removal of the finished tube. The guiding-means may be a substantially semicylindrical member 25 of sheet metal or other material, hinged at 26. The member 25 may be provided with rollers 30 projecting through openings to contact with the material on the mandrel. In a modification, the guiding-means consists of rollers mounted between hinged end bearing members. In addition, a fixed curved plate 21 may be provided having fingers which rest in grooves in a roller 19. The mandrel is arranged to be lifted and swung round to facilitate removal of the tube. For this purpose, one end bearing is carried by a vertical rod mounted in guides so that it can be raised, together with the mandrel, by a pedal, and rotated.

Abstract: 789,466. Respiratory appliances. ARO EQUIPMENT CORPORATION. June 14, 1955 [Dec. 13, 1954], No. 17068/55. Class 81 (2). [Also in Group XXIX] A valve connected between an aviator's breathing mask and an oxygen supply bottle carried by the aviator and which automatically opens in the event of a parachute jump, comprises a valve body 10 mounted on an oxygen bottle 14 and connected by a tube 23 to a breathing mask. The body houses a normally closed, spring-loaded valve member 24 which is operably associated with a toggle comprising levers 43, 44 mounted on a pivot pin 46 and over-centre springs 52. The toggle is connected by a link 55 to a reset stem 54 held in inoperative position by a shear-pin 55b and connected by a flexible cable 62 to a quick-release mechanism A. The quick-release mechanism comprises a hook member 86 connected to the aircraft structure and a spring-loaded pin 68 secured to the member 86 by means of indents 72 in the pin, balls 76 and a collar 74. On a jump being made the cable 62 is tautened, whence the stem 54 operates the toggle to unseat the valve member 24. The pin 68 is subsequently pulled downwardly against its spring so that the balls 76 are released and the pin 68 freed from the member 86. Prior to jumping, the aviator should remove the shear pin 55b but in the event of this being overlooked it will be sheared by the stem 54 when the cable 62 is tautened. A removable cap 60 per mits re-setting of the valve in its closed position and a check valve 102 protected by a removable cap 112 allows the bottle 14 to be recharged. The oxygen from the bottle passes through a filter 34 and a ceramic pin 36 to regulate the flow.

A machine for assembling on printed circuit boards electrical components which are supplied as a belt in which they are held in position one behind the other by adhesive tape comprises raceway means for supporting the components one behind the other in a row and means for pulling the tape so as to advance the components and progressively reel up the tape after it has been separated from the components. The invention is described as a modification of the machine of the parent Specification. The means for cutting, bending and inserting the leads of the components are mounted within a casing 11 and include outside formers 16, cutters 18 and the driver-bar 28, Fig. 4. The raceway is secured to the cover-plate 40 of the casing 11 by a bracket 44 and comprises pairs of guidebars 50, 52. From the lower curved end of the raceway components are fed into operating position by notched feed-wheels 56 rotated step-by-step by a pivoted lever 60 actuated by an arm 70 which is moved counterclockwise by the driver bar as it is raised after inserting a component. The shaft 54 of the feed-wheels carries a pulley 84 which drives, through a spring wire belt 86, a pulley 106 on a shaft 108 which also carries a roll 118. Shaft 108 is mounted in an adjustable arm 110. In operation a belt of components with the tape on the right as viewed in the Figures is led down the raceway and is passed over an adjustable rounded finger 126 and on to the roll 118 which by its step-by-step rotation feeds the belt down the raceway, the tape being stripped from the components as it-is deflected around the finger 126. The feeding and separation of the components may be assisted by a star-wheel 98 also driven in a step-by-step manner from the shaft 54.
