Abstract: 1,010,826. Assembling electrical components; end capping rods and tubes. E. J. BRYNER, J. N. IANUZZI, and C. K. BRIDGES. Sept. 6, 1962, No. 34241/62. Headings B3A and B3Y. A machine for forcing cupshaped caps on to the ends of bodies such as resistor bodies, comprises first, second and third drums disposed on a driven shaft, spaced means on the periphery of the first drum to hold the bodies, means to drive the shaft, circumferentially spaced dies on the second and third drums to hold the caps with the open end of each cap in alignment with an end of one of said bodies, cam means adjacent the second and third drums and follower means on the second and third drums adjacent said dies engaging the cam means and forcing the caps over the ends of said bodies as the shaft rotates. The machine comprises a driven shaft 28 on which is fixed a body drum 51 and two cap drums 52, 53 slidable on the shaft and three vibratory feeders 43, 44, 45 all mounted on frame and bearing support members 11, 12 and 20. The three drums are locked together and in alignment by pins 54. The shaft is chain driven by a variable speed motor. A number of notches 60, for example twenty, formed in the periphery of the body drum 51 receive the component body parts from the feeder 43 via a shoot 46 and a loader assembly 47. The position of the cap drums 52, 53 is controlled by the position of stationary cylindrical cam supports 66 bolted to axially adjustable pedestals 61 and two screwed collars 70. Compression springs 75 located in blind holes urge the cap drums apart. The caps with a wire attached thereto are fed from the feeders 44, 45 to cap loaders 50, 51a so that the caps rest on a surface 92 with their open ends facing the bodies on the drum 51. The cap loader comprises a spring-biased arm 102 having an extension 15, slidable along a face 103 of a seater 100 supported on the cam supports 66 slightly ahead of the cap loader to which is attached a stepped cam 107. Pins 113  spaced around the periphery of the cap drums 52, 53 successively engage the cam 107 to move the arm 102 against the springs and the end 115  to push a cap into a hardened cap die 119. A stripping finger 118 fixed to the cap drums below each die and extending into the die cavity by way of a slot 118a ensures that any jammed component is ejected from the die on its return stroke. The dies 119 are spaced around a ring 131 having peripheral segments separated by radially extending slots 116 through which the wire of the cap passes. As the cap drum rotates rollers 126 rotatably supported in spring-biased members 121 engage a fixed cam 132 on the inner face of the support 66 to cause the member 121 to move inwardly and the die 119 to force the caps on to the ends of the bodies. The capped bodies are removed from the drum by gravity. Ejector arms 142, 143 disposed about each side of the body drum ensure that any jammed bodies are forcibly removed. The loader 47 comprises a slider 152 actuated by a roller assembly 154a each time it engages a notch 60 to depress a body supplied by the shoot 46 into a guide 145. A fence 224 at the upper edge of the feeder bowl 45 causes the cap lead wires to swing outwardly prior to their moving down an incline 230 and through a covered section 231 to a rectangular sectioned shoot 48. In the event of a build-up of caps on the fence an air jet 233 and a notch 234 permit the unit to tip horizontally and reject the caps back into the bowl.
