partieularly on larger sizes used vfor air-` plane work and the method of driving the ignition generator, or` `the distributor, where the.r distributor.` vis mounted separate from the generatn, must be givenav great deal of attention.

Itis the objectof my inventionk to `provide a mounting for theirotating .part or parts ofvlthe -distributor which will ywithstand vibrationfand prevent oil, dirt and other foreign matter from working through into Other. ob 'e'cts will be Veplguireiet to lone Askilled-fin thisrart after a study oftheSpeciclationend the drawings annexed thereto showing par-tof the means for mounting the distributor baseftothe engine as well as a part of the rotating finger.V

' Referringnow tofthe details, wherein like numbers refer. to corresponding parts in the various views, 1 illustrates a part of an engine housing through which passes a shaft carrying `a gear-2. The gearf2 is in mesh within"` gear 3 fastened on to a shaft 4 herelinafter referred to as the driving shaft; The

shafttl is hollowv and slotted at the outer end for a'purpose which will be later referredto. 5 afdistributor basehaving a hub 6 which projects within the'flange 7 which is fastened tothe part 1. A distributor block 8 is adapted to be fastened to the base 5 by a suitable number of studs 9., nuts 10 and lockwashersll. BlockrS carries an annularl ring 12 connected to a binding post 13. Mounted' for rotation within the housing' formed by the base D and the block 8 is a @Hallie and thedistributing l th` line -B'through the shaft drivingy the distributing finger 145, having a brush, 1,5` atleet-ed te engage Contacts reuntedwthn the inner'surfacefof the distributor block 8.

The distributing finger 14 carries a brushl 19 which is oontinually in contact with the annular ring 12 l as well as being in continualcontact with A s shown in Figure 1, every alternate; con" terminal 1.3isA distributed the brush 15 tothe contacts 16 and 17 as the finger 14 is;V rotated.

It will be understood that the `working or service brush 15 delivers currentto-the contacts 16 and 17 at intervals of 2%L and371lthebrush 15V so that Current connected tothe as aV trailing for startingV Contact,l aV specialv degrees of rotationof thedistributing finger end, as shown in Figure 2, a lockwasher 24 and snap ring 25 being used to secure the finger ,1.4 in Aplace within the holder 23.

.ln the assembly of my device a piece of packing 26 is secured in the flange 27 of the base 5 and the outer ball race 30 pushed in place. The hase 5 is then ready to receive the holder 23 on which the inner ball race 28 and ball retainer and inner spacer 29 have been mo-unted. The packing 3l, preferably of felt, is then put in place followed by the outer spacer 32. The outer ball race 33 is then put in place within the hub 6 followed by the ball retainer and the inner race B4. The washer 35 and snap ring 36 may then be put in place and also the washer 37 against which are placed a number of strips 38 which fit within a slot in the end of the holder 23, being riveted thereto by rivet 39. As will be seen from Figure 3, the strips 38 are long enough to pass through the wall 40 of the hollow shaft el. The strips 3S are preferably of thin resilient material, such as spring steel so that a flexible driving connection is afforded between the driving shaft 4 and the finger holderl 23 after the finger and base have beeny put in place as shown in Figure 2. following' the assembly of the various parts to the base 5, as hereinbefore described. held to the engine member 7 by any suitable number of bolts 41, vfour being shown in Figure l, a tie wire 42 being fastened. through a pair Vof such bolt heads to prevent their turning. The base 5 `also carries a 4vgasket or packing i3 to prevent dust and water rfrom working in around the edge of the base and distributor block which is then attached to the base in a manner previously described thus completing the assembly or inoi'lnting of the entire structure to the engine. A drain passage 4.4: is provided. shown in Figure 2, to carry away any oil.

I orother vmaterial which passes through the bearing or bearings to a point adjacent the packing ring 26.

While l have shown a preferred arrangement of parts, it will be apparent that various changes may be made and I therefore, donot wish to be limited to the exact details shown and described. except as limited by the appended claims.
