Filed: 1926-10-19
Abstract: 272,373. K÷llner, M., and Leipziger Schnellpressenfabrik Akt.-Ges. vorm. Schmiers, Werner, & Stein. Oct. 19, 1926. Machines using continuous wire.-In a stapling machine using continuous wire and having former and driver bars and wire feed mechanism mounted on a fixed head, for example as described in Specification 143,919, former and wire-feed bars are sd coupled to the driver bar as to be operated by an operation of the driver bar and to be disconnected from it while it completes its driving stroke. As shown, a driver bar 3 moving in a fixed head 2 is operated by a lever 4 and rod 5. The bar 3 has a pin 11 passing through a slot 14 in a wire feed bar 13. Fig. 2, and moving in a slot 16 in a plate 17, of the form shown in Fig. 3. movable in a recess 19 in a fixed plate 18. The plate 17 is pivoted to the bar 13 by a pin 15. When the bar 3 commences to descend, the pin 11 is in the angular part of the slot 16, so that the bar 13 also moves down to operate the wirefeed machanism, not shown. When the feed is completed the plate 17 has moved below the part d, e of the recess 19 so that it can tilt about the pivot 15, allowing the pin 15 to enter the vertical part of the slot 16, so that the driver bar 3 continues its descent alone to complete the shaping and driving. The bar 3 is similarly coupled by pins 8, 9 and a plate, not shown, similar to the plate 17, to the former bar 10 carrying shaping devices, not shown, so that the bars 3 and 10 first move together, and the bar 3 then continues alone for driving.

Title: Improved system of washing and filling locomotive boilers
IPC: B61C8/00
Filed: 1932-09-20
Abstract: 404,405. Emptying, washing-out, and refilling steam boilers. ECONOMICAL BOILER WASHING CO., Ltd., and SOUTH, E. J. H., 3, Central Buildings, Westminster. Sept. 20, 1932, No. 26153. [Class 123 (ii).] In a system for utilizing the hot water and steam blown out of a locomotive boiler for washing-out water and for heating fresh water for refilling the boiler, as described in Specification 14840/08, [Class 123, Steam generators], the blow out water is forced through an underground pipe line 1 into a separator 3 either by the steam pressure in the boiler or by gravity assisted by a pump 23. A switch 20 is so operated by the pressure in the pipe line 1 that when the pressure falls below a certain point a circuit is closed through a motor 21, which operates a valve closing comcommunication between the pipe line and a pipe 4 leading to the separator and opening communication between the pipe line and a pipe 22, through which the water is forced into the separator by the pump 23. The pump is started simultaneously with the closing of the switch. Water flows from the separator through tubes 66 in a fresh-water heater 6, and through a small storage tank 7, and is then delivered into the wash-out water tank 8 by a pump 9. A flop valve 10 in the pipe between the separator and tubes 66 operates a valve 11 in the fresh feed-supply pipe 12a. Water from the cold main flows through tubes 88 in the tank 8, then through the pipe 12a, heater 6 and pipe 14 into the filling-water tank 13. A return pipe 15 allows the water to circulate between the tank B and the heater 6. The flop valve automatically starts the pump 9 delivering water to the tank 8. Steam from the separator passes through a pipe 16 to a heater 17 in which is heated fresh feed flowing through a branch pipe 12b from the supply pipe 12a under the control of a thermostatically operated valve 19. The heated water flows into the tank 13 through a pipe 17a. The pumps 25, 26 deliver washout and refilling water through compression bells 27, 28 in the respective pipe lines 25a, 26a. The electric motors operating the pumps are controlled by cut-out switches operated by the pressure in the pipe lines. The water in the tanks 8, 13 may be further heated by live steam supplied from another boiler under the control of thermostats.

Abstract: 1304028 Traversing yarns E I DU PONT DE NEMOURS & CO 1 June 1970 [3 June 1969] 26371/70 Heading D1J A process for winding yarn into cylindrical yarn packages by traversing the yarn through successive stroke lengths to form a package of layers of helical coils, each coil having substantially the same helix angle, is characterized in that the coils are laid down at their reversals in differently shaped curves in a repeating progression throughout the winding of the package. The stroke lengths may also vary in a repeating manner. The traverse may be effected by using a grooved barrel cam having two or more yarn traversing cycles per one or more revolutions of the barrel, the groves being curved differently to each other at their traverse ends.  At least two successive reversal curves and corresponding stroke lengths in the repeating progression may be the same, the remaining curves and stroke lengths in the repeating progression being different therefrom. Several suitable multi-cycle barrel cams are illustrated.

A pendulum 1 carried by a pivot pin 2 arranged transversely of the vehicle normally rests against an abutment 3 and is connected by a link 6 to a piston 4 working in a cylinder 5. The latter communicates by a duct 9 with a chamber 7 closed by a diaphragm 8. A cover 10 is provided carrying two insulated contacts 11, 12, and a vent 10<a> is provided above the diaphragm. The piston may be a sufficiently loose fit or a needle valve may provide suitable leakage for the cylinder. The diaphragm is provided with a plate 13 forming a part load which may be provided by the attraction on the plate of a bar magnet 13<a>. When the brake is applied gradually, the diaphragm is not raised, but when applied sufficiently suddenly the diaphragm is raised and a contact plate 14 engages the contacts 11, 12 making the circuit of a horn 19 worked by a battery 18. A push 20 is provided for working the horn in the usual way and a switch 21 for cutting out the automatic mechanism. In a modification, the piston acts by suction. In a second modification two pendulums are provided with different degrees of damping. On an excessive rate of acceleration, the more lightly damped pendulum swings out and contacts with the other causing the horn circuit to be made. In the form shown in Fig. 4, a U-tube is mounted on a heavily damped pendulum 1. Mercury 32 in the tube 31 may make contact between wires fixed into the wall of the tube and close the circuit 16, 17. If the braking is gradual, mercury and pendulum swing together and the circuit is not completed. If the braking occurs suddenly the mercury swings in advance of the pendulum and the circuit is closed. An auxiliary or relay circuit may be provided for sustaining the signal as long as the brake is applied or until the vehicle comes to rest.
