Title: Improvements in and relating to lubricating systems for rotary blowers and the like
IPC: F04C29/02
Filed: 1930-11-24
Abstract: 357,012. Lubricating rotary pumps or blowers. BECKER, O., 8, Gennebreckerstrasse, Wuppertal, Barmen, Germany. Nov. 24, 1930, No. 35367. [Class 12 (iii).] In a rotary pump or blower comprising an eccentric rotor 3 with radially-sliding blades 6 and an oil chamber 13 in the base of the machine open to the pressure chamber 12, oil is forced from the chamber 13 to parts B, C of the cylinder 2 between the outlet slits 10 and the inner dead point x by a separate pump driven from the rotor shaft 4 by worm gearing 28 .. 31. The gas issuing from the outlet slits 10, which are distributed over the whole length of the cylinder, impinges on a baffle-plate 20 which prevents agitation of the oil in the bath and causes oil to be separated from the gas. The pump piston 27, Fig. 4, is slidably keyed in the gear 31 and carries a disc 32 formed with a cam groove 33 engaged by a pin 35 whereby the piston is both rotated and reciprocated in the cylinder 34. The operative end of the piston has a longitudinal bore 37 communicating with radial holes 38 .. 41. The groove 33 is so formed that while the pump draws oil on the suction stroke through a pipe 24, a passage 42, and the hole 38, the discharge stroke is in three stages, whereby oil is discharged successively through the holes 39, 40, 41 to passages in the cylinder 34, of which two communicate by pipes 25, 26 with the parts B, C, while the other passage 44 serves for lubricating the oil pump parts. The chamber 13 has sight-glasses 14, 15. and filling and draining plugs 16, 17, and the chamber 12 is provided with a relief valve 22.

[Classes 35 and 38 (iv).] Exciting. - An electric generating plant, for example a vehicle lighting installation, where constant voltage is required with varying speed, comprises a main generator G having a self-excited field winding 1 and a counteracting winding 2 fed from an exciter H coupled to the main generator, the field circuit 3 of the exciter including one or more parallel connected triode valves 4, the grids of which are connected with the sliding contact of a potentiometer connected across the main generator terminals from which also the cathodes are supplied in series with a resistance. As shown, a single valve is employed and a battery B in the grid circuit maintains the grid negative with respect to the cathode. With increasing voltage of the generator G, as the result of an increase in speed, the valve allows an increasing current to pass through the winding 3 whereby the field of the generator is weakened. In a modification the cathode of the valve is connected in series with the main field winding 1, resistance being connected in parallel with the cathode if necessary. The generator G may be provided with a compensating or compounding winding. The winding 2 may be dispensed with and the exciter H connected in series with the winding 1. The Specification as open to inspection under Sect. 91 describes a form in which the auxiliary generator is self-excited or fed from a separate source, a thermionic device in series with the field winding being influenced by the main generator voltage. In another form, a diode is connected in the exciter field circuit. This subject-matter does not appear in the Specification as accepted.

The governor is mounted on a shaft 68 co-axial with the sleeve 50, the shaft 68 being driven through a pin and slot connection 74, 76 from a fuel cam 62 which reciprocates the pumping plungers. As the speed increases the governor weights 82, 84 cause leftward displacement of a collar 86 and, via a coupling 92, the sleeve 50. Movement of the sleeve 50 is resisted by the bias of a spring 102 disposed between the sleeve and a shoulder 106 on the shaft 68, the spring having a non-linear characteristic so that the movement of the sleeve is rendered substantially proportional to the rotary speed. A further spring 104 disposed between the other side of the shoulder 106 and the face cam 62 contracts to allow the shaft 68 and the sleeve 50 to move together when the vacuum device 70 operates a lever 80 axially to displace the shaft 68. The alternative governor shown in Fig. 7, comprises a U-shaped carrier 128 fixed to the shaft 68 and weights 82', 84' pivoted respectively to the legs 132a or 132b of the carrier by pins 90. A lever portion 134 of each weight is connected by a tension spring 112 to the other leg of the carrier, the springs 112 having linear characteristics. The disposition of the springs 112 are such that the movement of the sleeve is again proportional to the speed.
