To @ZZ whom it may conce/rn VBe .it known that we, Go'r'rLoB lIUnGEL and HERMAN Soifiluin, who were Yformerly subjects of the German Empire, but Who have severally renounced all allegiance to said power and declared our intentions of becoming citizens or the United States, being therefore advised that at present we are not citizens of any country, residing in Brooklyn, in the county of Kings and State ot' New York, have invented certain new und useful improvements in Lubricating Devices, of which the following is a specification. A

Our invention relates to improvementsin lubricatingdevices; particularly lubricating devices to be employed in connection 'with bearings tor shafts that reilluire to have the positions oilz their axes varied.

Oui' invention is especially' adapted 'for use on inagnetos that supply electric current to the igniters or spark-plugs ot internal combustion engines; and our principal obj ect is tol lubricate the adjustable bearing of the shaft o't the distributer mechanism of an ignition magneto when such bearing is provided to enable said shait 'to be moved towards or ilrom the axis ot the armature oi' the magneto. and thus i'ender the .distributer shaft capable oi' turning at a relatively greater or smaller number oi revolutions per minute; so that tlie'magneto can be utilized, Without alteration of any ot its parts, except the distributer mechanism, upon engines having larger or smaller number ot' cylinders. i

A further object of our invention is to provide a lubricating device which is -intended for the adjustable bearing of the dis" tributer shaft of an ignition magneto; and which is designed'to lubricate said shalt most etliciently in all the adjusted 'positions of said shaft or the parts of the bearing carrying same. y Y

Other objects and advantages of our invention will be set out in the following description, taken with the accompanying drawings; and the characteristics oiz our invention Will be precisely defined in the appended claims.

.This application is a division of our prior co-pending application Serial No. 26855el vfor a patenten adjustable bearings, tiled December 27th, 1918, and is restricted to features of construction Wherebv ellticient lubrication is secured. L

In Figure l ive show at l a portion of a magneto for the electric ignition of an internal combustion engine. This magneto comprises among other things a rotatable armature, not shownr` carrying a gear indicated iii part at 2 meshing with a distributer gear 3; and all ot. the parts v oit the magneto` including the casing indicated in outline at d tor the gear il, will be suitably mounted by means ot a 'frame 'Work orhousing. The casing t will be held in place by securing the sume to a. support 6 which is on the housing land in ivhich our adjustableV bearing is disposed. In practice the armature, which will rotate on .an axis parallel to the gear 3 and carry the gear 2 to drive thel gear 3, as stated` will. be provided ivith a loiv tension or primary winding and a. high tension or secondary Winding; and ivill include a timer for breaking the circuit ot the primary Winding and a distrilgiuter for supplying the high tension or secondary current to the spark-plugs or igniters of the engine are respectively a front and 8 are respectively a frontcylinders.

We do not illustrate either the timer or the distributer mechanism here, as thegeneral construction and inode of operation of the same and of the entire magneto are well known; and the distributer mechanism always includes a rotating contact which is carried by the @ear 3 and completes the circuit to each spaiil-plug in succession as the gear 3 turns. For a four. cylinder engine the gear 3 must be twice as large as the gear 2 andtherefore rotates at onehalf'the speed of the latter; while for six cylinders, the gear 3 must be .three times the size of the gear 2 and therefore rotates at one-third the speed thereof. Hence if the magneto is to be changed so as to adapt it for a six cylinder,engineinstead of a four cylinder engine, the distance betweenv the axis of rotation of the gear 3 andthe axis ofthe armature must be altered. If for example, the gear 3 is twice as big as the gear 2 and rotates at one-half the speed of the gear 2 and we wish to have the gear rotate at one-third ofthe speed of the armature, `we preferably attain our object by replacing the gear 2 with a slightly smaller gear and the gear 3 with a slightly larger one. j Such a change involves the replacing of the casing 4 with a slightly larger casing and themoving of the axis of rotation of the gear l3 farther away or upward from the axis of the armature. If, on the other hand, the gear 3 is three times as big` as the gear 2 and rotates at one-third the speed ofthe gear 2 and we desire to have it rotate Y yonly one-half the speed of the armature we proceed accordingly byV mounting on the armature a little larger gear 2 and choosing a little smaller-gear 3 and casing 1, and inoving the axis of the gear 3downward towards the axis of the armature to the required extent. The casing 4; is of course held to the supportl 6 by means of fastening devices which can be easily removed to enable a suitable gear casing to be easily put on or taken off, and our adjustable bearing, mounted in the support 6, permits the locationvof the axis of the gear 3 at thenecessary distance from the axis of the armature in a manner now to be described. Y

As shown in Figures 1 and'2, the support 6 has an aperture 7 therethrough. This aperture 7 is elongated vertically and it receives a bushing S which has an eccentric opening 9. This bushing is inserted into the aperture 7 from the rear; that is, from the face of the support` G opposite tovthat which abuts against the casing el; and the openingV 9 receives an eccentric sleeve 10 which has an eccentricbore 11 for the sha ft p or journal 12 of the gear 3. Owing to the shape ofthe aperture 7 and the configuration of the bushing 8, the axis of the shaft 12 can be located closerto or farther from the axis of the armature,accordingto the position of the bushing 8 in the support 6.

is shown in Figures 1 and2, the axis of the gear 3 is a certain distance from the were reversed or inverted in the aperture 7, the axis of the gear 3 would be moved farther away from the armature axis. As

indicated in Figure .1, the bushing 3 terminates short of the front face of the support 6; while the sleeve 10 extends all the way :through thisbushing and beyond the front Y to make theteeth of the gear 3 and the gear 2 go into proper mesh with one another.

As Figure 2 shows, the aperture 7 is vaxis of .the armature, but if the bushingYV rounded at the top and bottom and flat at the i sides. Therefore it is symmetrical as regards both its longitudinal or vertical axis, and its transverse or horizontal axis. The bodyzof the bushing 3 has the saine shape and therefore may he described as symmetrical in the saine respects, and as havingrounded ends or portions 13 and flat sides 141. VOn one face it has a flange 15, which, when the bushing is in the aperture 7, will fit against the rear of the support 6. Of course the opening 9 is circular. y Y

Thesleeve 10 is circular on its outer face and has polygonal flange 16 at its rear end to enable the same to be turned in the opening 9. At its opposite end it is counter-sunk or recessed to provide a shoulder 17 around' the edge of the bore 11 to receive a washer 18, which is held on the shaft 12 between the rearface of the gear 3 and ashoulder on the shaft; and the sleeve 10 will preferably lit against this washer so that end play or axial niovenient ofthe` gear 3 is prevented.

The bushing 8 is provided Vin one of its rounded portions 13 with a groove 19 and likewise with a recess 2O in the opposite rounded portion.v When the bushing is in the aperture 7 this groove and thisrecess will be engaged by fastening means, such as bolts 21 whichpass through passages extending'froin sideto side of the support 6. Hence the displacement ofthe bushing from the support is prevented. VThe lower recess 20 goes through the'body of the bushing and coinmunicatesvwiththe opening 9; and the sleeve 10 has a peripheral recess/or groove 22 which is engaged by one of the bolts 21; such bolt projecting laterally throughthe recess 20 into the Vgroove 22, and axialV movement of the sleeve 10 islikewise'prevented. To reverse or invert the bushing vthe bolts 21 are removed,- and replaced when the reversal or inversion iseffected. The bolts 21 may be roughened where they engage the grooves 19 and 22, to make them hold the bushing and sleeve securely.

rThe top of the casing 4 will have an oil opening 23; from which leads a duct 24 which will register with a space 25 in the support 6 leading to the space in front of the bushing 8. In the lower end of the aperture 7, just in front of the bushing 8, we provide an oil groove or channel 26 and in this groove we place a body of absorbent material such as a segment of felt 27, shown in Figures 1, 2 and 9. The oil which passes down into the space in front of the bushing 8 will saturate the body 27 and any excess will collect in the groove 26. The body 27 will make contact with the outside of the sleeve 10, and we preferably provide in the plane of Contact and at equal intervals apart three holes 28 which lead through from the outside of the bushing 10 to the bore 11. These holes may be filled with fibrous material to form wicks and the oil from the body 27 will soak through these wicks and spread over the inside of the sleeve l0 and the outside of the shaft 12, thus lubricating the gear thoroughly.

The shaft 12 is held in the sleeve 10 by any suitable means to engage its rear end.

By the above construction we are enabled to use the same magneto for either four or six cylinder engines merely by changing the gears 2 and 3, with the shaft l2, together with the casing 4t and distributer plate which carries the high tension binding posts. At the same time efficient lubrication is obtained under all conditions.

When oil is poured into the opening 23, it either drips upon the sleeve 10 and saturates the wicks in the holes 28, or it runs down the sides of the opening 8 into the groove or recess 26 and saturates the felt 27. At least one of the wicks will always be in contact with the upper edge of the felt 27, which will be compressed by the sleeve 10, as indicated by the broken curved line in Figure 9, and lubrication for all positions of the shaft 12 is thus assured.

Having described our invention, what we believe to be new and desire to secure and protect by Letters Patent of the United States is:

1. The combination of a support having an aperture'and a recess in said aperture, an eccentric sleeve in said support to engage a shaft, absorbent material in said recess and engaging said sleeve, said sleeve having holes therethrough containing absorbent material tomake contact with the absorbent material in the recess and conduct lubricant to the inside of the sleeve.

As an article of manufacture, an eccentric sleeve having a bore therethrough and holes to admit lubricant to the inside of said sleeve, and absorbent material filling said holes.

3. The combination of an adjustable bearing sleeve, and a body of absorbent material to be saturated with lubricant and make contact with said sleeve, the latter having openings to enable lubricant from said absorbent material to penetrate to the inside of said sleeve.

4. As an article of manufacture, a sleeve having an eccentric bore and having one end recessed and a polygonal flange on the other end, said sleeve also having an external groove to be engaged by fastening means, and having one or more holes therethrough to admit lubricant to its interior.

In testimony whereof, we have signed our names to this specification this 22nd day of May, 1919.
