IGNITION DISTRIBUTOR Application filed December 26,1923. Serial No; 682,716.

This invention relates to a distributor for electrical current and as illustrated is par ticularly adaptedfor use in the distribution of ignition current to the various cylinders of an internal combustion engine.

Theprincipal object of my invention is to providea distributor for a multi-cylinder engine, to which the cables may be quickly attached with the least amount of work. It is another object of my invention to provide a distributor which is relatively simple in construction yet eiiicient in its operation. 7

Other objects will be apparent to one skilled. in this art after a study of the drawings taken in connection with the specification.

In the drawings:

Figure 1 is a plan view of a distributor with the cover removed,

Figure 2 being the inner part of the cover fitting over the distributor shown in Fig. 1.

Figure 3 isa sectional view on the line 3/3 of Fig. 1 but with the cover and other parts in position.

Figure 7 is a plan view of the rotating distributing member shown in Fig. 4.

Figure 8 is a side view of Fig. 7 v

Figure 9 is a fragmentary sectional view on the line 9/9 of Fig. 1. f

Figure 10 is a fragmentary plan view similar to Fig. 1. but of the distributor block shown in Fig. l with the cover re moved.

Referring to the details wherein like numbers refer to corresponding parts in the various views, 1 is a supporting member in which a pair of frictionless bearings 2 are positioned for the purpose of carrying anv Q operating shaft 3. In Fig. 4 a plain bearing 4 is used instead of the ball bearings shown in Fig. 3. Carried on the stubv shaft 3 is a collar 5, the same being held there in any suitable manner as by nut 6. To the collar 5 is attached a distributing member 7, the same being heldto the collar 5 as by screws 8 only one being shown in the sectional view Fig.3. The distributing member 7 is ofv any suitable insulating material and preferably moulded thereimis an insert 9, having a centrally located contact 10. To therinsert -9 is attached a main contact terminal 11, as

by means ofa screw 12.

Thesupport member 1 is fastened to some part of the engine casin as by means of a suitable number of screws 13. Carried on the support member 1 isa blockof insulating material 14:, which is held to the member 1 in any suitable manner as by screws 15. The block 14 has a number of substantially radially arranged recesses or channels 16, which are deeper toward the edge of the block and slope or taper upward toward the center thereof as is clearly shown in Fig. 3. In the deeper part of each of the channels 16 is positioned a contact 17sh0wn in the form of a stiletto pin. This pin is. securely fastened to a plate 18 and the two together are preferably moulded integral with the block 14. There is an opening through the bottom of each channel and positioned in this opening is an ignition pin 19. which in the form shown is arranged so that it can be riveted to the plate 18 after the block has been moulded. I prefer this arrangement because of the large number of-pins 19 projecting downward in opposite direction from the stiletto pins 18. makes the withdrawal of the whole block from the mould diflicult. as the lower projecting pins are likely to be bent.

Therefore. I have constructed the block so that the ignition pins 19 may a separate operation.

The channels 16 are of such depth that the high tension electrical cables 20 lying therein will be forced downward over the stiletto pin 17, which thereby makes contact with the conductors 21 and at the same time the cover 22 will press against the upper surface of the cable 20 and hold it securely in pobe put in as sition in the channel and over the pin 17.

This holding action of the cover on the cables is improved by means of a series of ridges 23 moulded in the cover. The cover in Fig. 3 has a central opening 24 through which all of the cables lying'in the channel 16 may pass. In addition a centrally located cable 25, coming from the ignition coil or an igni tion magneto, is attached to a-nfinsert 26 through the medium of a wood "screw 27, it being understood that the strands of the conductor 21 pass through little iri'ith'e the auxiliar3 source oi starting current to one of the studs which 18 used tor hcilding the cover to the distributor block.

hown riticularly in Fig.

. nected to the stud ion may be indicated by The distributor '1' q dotted men do p05 line shorm. in Fi T as shown carries an annular 83, ch is adapted. to cooperate with the contact and the is connected by means at a conductor "i (see Fig. (I) to an ignition pin tl at is in the same plane w th. contact ll... but set at. an angle trailing behind the main contact ill. (see The parts 3 and 3:) are shown in dotted position in Fig. but at an angle oi apl'n'oxiiuatcly 180 degrees tor the purpose ot clarity. The purpose of the trailing brush is to allow the starting ignition current to be applied to one of the work ng; cylinders at a time utter the given piston has gone over compression.

In order to prevent the starting ignition current :trom jumping from the annular ring; 83 to any part; of the metal. support member 1, I provide a. barrier 36 which in the iiorm shown in Fig. 3 is an insulating disc but in Fig. t it is the bottom of the distributor block. It will be readily obse wed that the pin 82 may be placed in the member 7 and the annular ring may be placed in the distributor block as is sho 7m n Fig. =1. In this particular figure the distributor block is made in two

sections

37 and 38, the upper section 37 being; constructed so that it may be rotated with respect to the lower section and the distributor member 7 for the purpose of adjusting; the gnition pins 19 with respect to the main distributor contact 11, after wuich adjustment has been performed. the section 3'7 is locked by means of a screw 39 passing through one of the studs 31 into engagement with. the serrations 40 which may be moulded in the section 37 (see Fig. 1.0). This adjustment is observed through a peep hole c'orered by a piece 0t. non nliammable insulating material, such as mica illustrated by the numeral 4-1 (Fig. 8).

In the forms shown, the distributor is what is known to the trade as the jump spark type, rather than the wipe contact type.

The cables instcad ot leaving the distribulor tron! the ccntcr in Fig. -l. lcare he block radiall; and the holes 12 through tl c hloclr ii "for SflCllllllg the pins 19, are some that deeper than in Fig. 3: Also the cable 30 from the starting ignition source is attached to the ring 33 in a 7 dilicrent manner than in Fig. 3. l. be a p arcut that various changes made in the detailsv without departt ot my intention and the "t the appended claims. .lla'rinp' thus described my invention. what I claim is:
