Title: Improvements in automatic coin freed sales apparatus for tickets, postage stamps andother articles such as labels cut from a strip
IPC: G07F11/68
Filed: 1928-04-03
Abstract: 305,008. Eller, F. Jan. 28, 1928, [Convention date]. Delivery of postage stamps &c. cut from strips; casings; "empty" notices, displaying. - A coin-freed apparatus for delivering tickets and other articles cut from strips is provided with an illuminating system, the current supply to which is controlled by the ticket strip so that the supply is interrupted when the strip is exhausted. The ticket strip 6 is led from a roll 7 over rollers 8, 9 and through a printing mechanism 5. The ticket cut off drops into a delivering tray 10. A roller 16 carried by a lever 15 rests on the strip above a groove in the roller 9, and, when the strip is exhausted, enters the groove. The resultant movement of the lever 15 depresses a rod 20 pivoted to a signal arm 22 which is rockably mounted on a pivot 21. The signal 22 is thereby raised to indicate that the machine is empty and an arm 23 closes the coin insertion slit 27. A pin 24 on the signal acts on the arm 26 of a bell crank lever to cause its other arm 26<1> to raise a switch arm 25 and break the circuit of an electric lamp 2 mounted on the back wall of the machine. The lamp 2 illuminates the interior mechanism, which can be seen through a window in a door 11, and also inscriptions borne by transparent panes mounted in the door. The signal mechanism is mounted on the back of the door so that, when it is opened for the ticket mechanism to be put in order, the switch arm 25 falls and the lamp 2 is again lit to permit the attendant to examine the mechanism. When the door is shut, if the arm 22 has not been restored to its down position, the lamp becomes extinguished to show that the mechanism is not in order.

Title: Improvements relating to cutting tools
IPC: B23K31/02
Filed: 1962-03-16
Abstract: 996,479. Making cutting tools; welding by pressure. DO ALL CO. March 16, 1962 [May 18, 1961], No. 10190/62. Headings B3A and B3R. A method of providing a hard cutting edge for a steel tool comprises electric welding an end of a rod of material harder than that of the tool to the tool where the cutting edge is to be located, severing the rod and shaping the weldedon piece of hard metal into a cutting edge. A series of teeth 7 formed in a steel strip, e.g. a saw band are provided with tungsten carbide cutting tips 6 by fusion welding a piece of a tungsten rod 18 on to each of their front faces 12. The rod 18 is supported in a collet 19 of a movable slide member 20 which is advanced until the rod end face 18<SP>1</SP> is in contact with the tooth face 12 to complete the welding circuit. The tooth face is allowed to reach its fusion temperature and the rod end its forging temperature prior to the rod being further advanced and fused to the tooth face. The junction is annealed by adjusting the welding current and the collet pressure released from the rod to allow the slide to move away from the tooth sufficiently to allow a thin sectioned diamond edged cut-off wheel to sever the rod along a line L. The teeth are finally ground to their required form. The welding is carried out in an inert atmosphere of argon or helium, the welding current supplied with the slide 20 and holder 22 and the toothed strip suitably indexed to the working station. In a modification a tungsten carbide tip is similarly welded to other cutting tools used, e.g. in lathes, shapers, boring mills &c.
