11 Claims. (01. 123-148) The object of this invention -is to solve the problem of attaching a coil to a combined distributor of high tension and circuit breaker for low tension electricity for an internal-combustion' engine, so that the coil may be attached and removed with the le'astpossible number of operations-and so (that. the action of attaching the coil to the distributor automatically connects both the high and low tension circuits of the coil to thehigh tension distributor and to the low tension circuit breaker, and the removal of the coil automatically breaks these connections.
An additional problem is to provide for the location of-the condenser, which is required to protect the circuit breaker points.
Fig. 1 shows the distributor, circuit breaker, coil and condenser-in cross-sectional elevation.
Fig. 2 shows the distributor in elevationas viewed from the left of Fig. 1 with'a partial section to illustrate the means for attaching the coil to the distributor.
F18. 3 is a plan view looking up on the bottom of the. coil.
- In the flgures:'-
Two tubular rivets 16 and 17 surround the 3%) screws 10 and 11, and a primary terminal '70 for the coil 12 is molded into the base 14 and receives abinding screw 18. A high tension carbon brush terminal 19 and its spring 20 is guided in a tubular rivet 21, which tube extends from the outer housing 22 of the 001112 to'and through the coil base 14. A fourth tubular rivet 23 serves to hold support 24 for the condenser 13, and is, oi course, connected to the primary circuit 25-26 of the coil 12. In a similar manner, the high tension cardd bon brush 19 is connected through the tube 21 with the high tension turns 27, 28, 29 of the coil assembly 12. It will be noted that the low tension turns 30'surround the laminated core 31. Now, thetube 17 also acts as a ground connection for the condenser 13 through the wire 32. The case 15 constitutes the ground for the screws 11. All these tubes (Fig. 1) 16, 17, 21 and 23 are of metal and are spun over at their ends so as to bet-securely anchored'in the coil dasing 22,
as which is of molded insulated material (Bakelite) 19. A flat spring contact 41 connects a conductor 40 with the circuit breaker 42, which is of a well known type and need not be described in detail. This circuit breaker is operated by a cam 43 mounted on a sleeve 45, in its turn mounted on a shaft 44, which is driven by the engine cam shaft 46. The sleeve'45 and cam 43 are driven from the shaft 46 and 44 by the governor 4'7, and the details of which are no part of this invention.
The shaft 48 is an extension of the shaft 46-44, and on shaft 48 is mounted/the distributor 33. A bearing 49 on a projection 50 serves to maintain the shaft 48 and the distributor 33 reasonably concentric within-the casing 15. A washer 51 and 23 are spun over so as to clamp the condenser base 24 to the coil base, 14, and the 0611 base 14 to the coilcase 22. A coil sealing gasket 55 maybe permitted to make a tightjob of the operation of riveting up the coil with its base 14.
The low tension circuit is as follows:--- The current enters from an ammeter to an ignition switch, and then through a resistance unit (not shown) to the terminal *70, (Fig. 2) which is provided with a screw 18 so that the low tension wire can be securely held in contact therewith. The terminai'm is moulded into the base 14 of the coil 12. The current then flows to the terminal 26 (Fig. 1) of the low tension winding 30. The current leaves the low tension winding at 25 (Fig. 1) and flows. through the conducting piece 24, also moulded into thebase 14. The current then flows to the condenser 13; one side of which is grounded through the conductor 32 (see Fig. 2) to the screw 11, which grounds the condenser into the base 15. The other side of the condenser is grounded intermittently through the circuit breaker 32 as 101- I lows: I
Current flows through the conductor 24 to the rivet 23, thence through the conductor 40, to a spring connection 41, which delivers the current to the circuit breaker 42.
The engine camshaft 46 is driven by the gear 73,which is provided with teeth 74 molded thereon. The high tension discs'36-3'7 are protected by-the covers 7'7 and '76 which are held in place by means of the bails 72 and 71.
