Filed: 1926-06-15
Abstract: 277,424. Anderegg, G. A., and Western Electric Co., Inc. June 15, 1926. Continuously loaded cables and conductors. - In making a continuously loaded conductor, loading material is wrapped on a conductor having interstices or interior air spaces and the conductor is then compressed in order to loosen the wrapping prior to the annealing heat treatment. The interstices may be forcibly closed during the preliminary loosening treatment. The process may be carried out by winding on a cylindrical core copper strips so shaped that their edges stand off from the surface of the core and after winding the loading material the wound conductor is rolled between grooved rollers. Alternative methods of wholly or partially closing the interstices may be adopted and reference is made to Specification 277,423.

IPC: F02M59/30
Filed: 1922-05-30
Abstract: 181,010. Junkers, H. June 1, 1921, [Convention date]. Cylinders receiving liquid fuel.-In a fuel pump in which the beginning of the delivery is constant with regard to the crank circle of the engine, while the end is variable, the variation of the end of the delivery is effected by means of an adjustable driving member positively actuating the piston. In the form shown in Fig. 1, the driving member is a cam 3 which is adjustable angularly on its shaft, and the constant beginning of the delivery is provided for by closing the inlet valve 4 of the pump at a definite position of the crank, as by means of the mechanism 6, 7, 9, 8, 10. In a modification, the crank 6 is angularly adjusted by the governor instead of the cam, the variable moment of opening the valve 4 determining the end of the delivery stroke. The valve 4 may be a by-pass valve, a separate suction valve being provided. A spring 4a holds the valve to its seat, so that it acts as a relief valve. In the form shown in Fig. 2, the plunger is actuated by two cams 11, 12 revolving in opposite directions, the cam 11 being fixed while the cam 12 is angularly adjustable. In this arrangement, the length of stroke is varied, but its beginning is constant. In the form shown in Fig. 3, the cam is in two parts 22, 25, the part 22 being pivoted at a point 21 eccentric to the axis 23 and having a periphery 24 concentric with the pivot 21, so that, however the part 22 is adjusted, the stroke begins at the same point on the crank circle. In a modification of the last form, the cam surrounds the shaft and is pivoted at point eccentric to the shaft. In order to prevent drip after the delivery stroke, the piston is rapidly withdrawn at the beginning of the suction stroke by providing a sharp drop on the cam from its highest point, or by equivalent means in the system of actuating levers.

Filed: 1928-05-25
Abstract: 291,106. British Thomson-Houston Co., Ltd., (Assignees of Stephenson, H. M.). May 27, 1927, [Convention date]. Driving; s p o o l s, winding. - An electric motor 7 is pivotally mounted at 12 on the underside of the workplate and has a sliding connection at 13. It is spring - pressed by means of a pivoted fork 14 to hold its friction pulley 10 in driving contact with a pulley 11 loose on the under shaft 9. The pulley 11 is normally clutched to the shaft 9 by dog-teeth on it and on the end of a worm 18 which is splined on the shaft 9 and drives the upper shaft of the machine through a worm wheel 20. The force exerted in this drive maintains the dog-teeth in engagement. If, when the motor is not running, the fly-wheel is moved by hand in the forward direction the wheel 20 moves the worm 18 away from the pulley 11 and disconnects the motor drive from the sewing-shafts. At the same time, a coned end 40 of the worm moves a lever 38, Fig. 5, outwards against a spring 14 until the lever rests on the worm thereby bringing a. friction pulley 36 into contact with the pulley 11. When the motor is started again the spool-winder shaft 34 is rotated alone. The parts are returned to their normal position by a manual movement of the fly-wheel in the reverse direction. Feed by dogs. - A cam on the vertical gear shaft 19 is embraced bv the end of a bar 26 slidingly pivoted upon a plate 27. The free end of the bar engages an inclined surface on the part 28 so that lengthwise movements of the bar 26 give a rising and falling movement to the feed-bar 29 whilst lateral oscillations of the bar 26 give lengthwise movements to the feed-bar. The length of feed is varied by movement of the plate 27 which carries the pivot of the bar 26.
