Title: Improvements in or relating to engine starting apparatus
IPC: F02N15/06
Filed: 1928-12-19
Abstract: 325,917. White, A. E., (Delco-Remy Corporation). Dec. 19, 1928. Turning-gear.-An electric starter comprises a pinion 31 movable along the shaft 22 of the starting motor into mesh with the engine gear 30 and automatically demeshed when the engine starts, the pinion having a lost-motion driving connection with the shaft and co-operating with a manually operated pinion shifting device 37 arranged to rotate the pinion prior to meshing and to take up lost motion between the shaft and pinion. As shown, the shaft 30 and the pinion 31 have inter-engaging helical splines, the splines 33 of the pinion being narrower than the spaces between the splines 32 of the shaft. The shifting device 37 is splined to engage the splines 32 of the shaft with little lost motion, and has tangs 37<a> engaging slots 36 in an extension 35 of the pinion. A compression spring 38 normally separates the pinion and the member 37 to the full extent allowed by the helical splines, and the shifter splines 37b, Fig. 10, normally engage portions 32<a> of the shaft splines which are inclined at a smaller angle to the axis than the main portions of the splines, in order to prevent the pinion from drifting into mesh with the engine gear. The shifting device 37 is actuated by a pedal-actuated lever 40 having a stud 50 engaging a notch 51 in a sleeve 52, the hub 53 of which slides on the shaft 22 and bears against the shifting device. The hub 53 is spaced from the sleeve 52 by discs 54, 55 mounted on the hub; the disc 54 has notches in its edge for engagement by tangs on the sleeve, and the disc 55 has a tang 57 slidable in a slot 58 in the sleeve, and is also engaged by tangs 59 on the sleeve. Frictional engagement between the hub 53 and the shaft 22 is ensured by a spring-pressed button 71 in an opening 70 of the hub. In operation, the pedal is depressed and the lever 40 bears against the slightly inclined face 65 of the slot 53, shifting the sleeve 52, member 37, and pinion 31 along the shaft 22. If the teeth of the pinion clash with those of the engine gear 30, continued movement of the member 37 a ong the splines 32 turns the member 37 and the pinion until the teeth come into register, when the spring 38 moves the pinion into mesh with the gear 30. The starting motor is switched on by a plunger 25 engaged by the lever 40. While the engine is being cranked, the sleeve 52 is rotated by the shaft 22 and the engagement of the inclined face 66 of the slot 53 with the stud 50 draws the sleeve 52 axially away from the pinion. When the engine starts, the pinion 31 and member 37 are moved axially out of meshing position by the helical splines, and on release of the pedal and the lever 40, the stud 50 re-engages the notch 51 of the slot 53. Specification 325,918 is referred to.

Abstract: 377,989. Cables. CHASE, P. H., 1000, Chestnut Street, Philadelphia, Pennsylvania, U.S.A. Jan. 24, 1931, No. 2446. Convention date, Jan. 25, 1930. [Class 36.] In an impregnated cable of the kind described in Specification 316,218, [Class 36, Electricity, Conducting &c.], provided internally with flexible and hollow pressure compensators, the compensators are maintained under internal fluid pressure during the manufacture, testing, transport, and installation of the cable. The pressure may be applied to detect leaks in the compensators or to prevent crushing of the compensators during the assembling of the cable parts and the application thereto of the lead sheath or to stretch the lead sheath and equalize the distribution of the impregnating compound throughout the cable. To facilitate drying, impregnating, and testing of the cable insulation, heated fluid under pressure may be circulated through the compensators. Fig. 4 shows apparatus for maintaining under pressure the compensator 4 of a cable 18, whilst permitting circulation of a heating or cooling fluid through the compensator. The ends of the compensator are connected to a closed circulating system 10 including a pressure gauge 21, a circulating pump 22, and a fluid-containing tank T provided with heating or cooling coils C. A pump P connected to the system through a valve 23 maintains the desired pressure or vacuum on the compensator. The circulating system may be isolated from the compensator by valves 26, 27. The apparatus may be used for testing installed and spliced cable sections, the pipes of the circulating system being connected to the compensator in the splices at opposite ends of the section. In a cable section having a plurality of compensators, the compensators may be connected together in one splice whilst the pipes of the circulating system are connected to the ends of the compensator in the other splice. Reference has been directed by the Comptroller to Specifications 241,628 and 264,135, [both in Class 36, Electricity, Conducting &c.].
