Title: Improvements relating to machines for notching sheet metal articles
IPC: B21D28/22
Filed: 1938-12-08
Abstract: 517,057. Notching armature discs &c. SANKEY & SONS, Ltd., J., and RICHMOND, D. A. Dec. 8, 1938, No. 35750. [Classes 83 (ii) and 83 (iv)] A device for transferring discs, such as those for armatures, to and from the supporting spindle of a notching-machine comprises two arms preferably at right angles carried by a rising and falling spindle, at least one of the arms having suction cups for taking the top disc from a stack. The discs 'are mounted by their keyways on the splined spindle of a support B on a sleeve slidable in a support 43 under the control of a spring that raises the support B when a clamp 45 is released by action of a cam on a rod 47 linked to a rod 49 sliding under the control of a cam 51 on a wormdriven disc 20. Just prior to the moment of release fingers 54 are swung into position above the stack of discs by linkage from crank pins on the disc 20. The stack of discs is raised by the spring against the fingers so that the top disc is at the right height to be engaged and lifted by suction cups d on a transfer arm D. The clamp is then released and the fingers are swung aside. A shaft F that carries the arms D and E is raised, rotated to bring the cups d over the disc, is lowered to engage the disc, the cups are connected to a vacuum chamber or pump and the arm is raised, swung to bring the disc over and lowered to place it upon the supporting spindle 68 of the notching machine and the vacuum connection is broken, releasing the disc. At the same time the other arm E, which when small discs are being notched is provided with an electromagnet instead of suction cups, has removed a finished disc from the spindle 68 and deposited it on a support H. The rising and falling motion of the shaft F is obtained through a ball thrust bearing 37 from a lever cam-operated at 34 from a second worm-driven disc 19. A crank pin 21 on this disc has a connecting rod with a slotted end having a frictional connection at 24 to an arm splined on the shaft; so providing a lost motion device enabling the arms to be swung as limited by adjustable stops 32. A cam on the spindle of the notching machine stops the motor 14, that drives the devices 19, 20, during the cutting of the notches. A projection on the end of the arm E engages the levers 73, Fig. 9 to raise the electromagnetic holder 70, that clamps the work during notching, to strip the finished disc from the spindle. A modified spindle for very small discs has a centre part 93 projected through a sleeve 92 and locked by spring pressed balls 101. A centre member 96a is depressed by the pin on the arm E camming out plungers 98 to press back the balls and release the part 93 which then descends with the part 96 stripping the disc. The vacuum is controlled by a valve operated by the lower edge of the cam 51 and a cam 81a controls the electromagnet on the arm F.

Nov. 28, 1930, No. 35910. Convention date, Nov. 30, 1929. [Class 37.] In heating units of the sheath wire type in which a coiled resistance wire 11 is embedded in compacted insulating powder 13 in a metal sheath 12 as described in Specifications 144,767 and 198,872, [both in Class 37, Electricity, Measuring &c.], insulating supports 16 are spaced at intervals along the wire 11 and are prevented from endwise movement bv reducing the sheath at the points 12a where it is desired to position the supports. The wire is thus prevented from being carried towards the lower end of the sheath during subsequent filling with the insulating powder 13. The supports 16 are formed with a cylindrical portion 16a, Fig. 6, and a flange 16b which is of square or polygonal shape to permit passage of the powder. The support 16 has a central aperture which is a running fit on the wire helix, which is flattened at each side of the support to position it. Terminals 14, 15 are secured by screwing the resistance coil on to threaded portions of the terminals as described in Specification 198,932, [Class 37, Electricity, Measuring &c.]. The lower terminal 14 has a washer 20 riveted on, the upper terminal 15 being held by a pin 21. After filling, a washer 23 is inserted at the upper end, and both ends of the sheath are spun over. The sheath is slightly compressed at points midway between the supports 16 in order to keep the resistance wire central, and the entire unit is then swaged down to a diameter equal to or less than that of the reduced portions 12a, the supports 16 being pulverized in the process. Transverse slots 16c facilitate this disintegration. The washers 20, 23 are then cut off and the ends of the unit squared to expose the terminals.
