COMPENSATING GEARING.

SPECIFICATION forming part of Letters Patent No. 726,930, dated May 5, 1903. Application filed March 20, 1902 Serial No, 99,038. (No model.)

To all whom it may concern.-

zen of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented certain new and useful- Improvemen ts in Compensating Gearing, of which the following is a specification, reference being had thereinto the accompanying drawings. 7

This invention relates to compensatinggearing, and is devised more particularlyfor use in connection with traction-engines, being in the nature of an improvement upon the construction set forth in Letters Patent No. 271,464, granted to me January 30, 1883.

The present invention has for its object to overcome certain disadvantages attendant upon the construction set forth in my prior patent above referred to; and to these ends it consists in certain novel features which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is an elevation, partly in vertical section, along the line 00 0c of Fig. 3 and looking in the direction of the arrows of a compensating gearing embodying my invention in one form. Fig. 2 is a plan section taken on the line y y of Fig. 1 and looking in the direction of the arrows. Fig. 3 is a view taken in section on the line ,2 z of Fig. 1 and looking in the direction of the arrows, and Fig. 4 is a sectional view taken on the line 2 z of Fig. 1 and looking in the direction of the arrows.

In the said drawings, 1 indicates the main driving-gear, to which the power is applied and which comprises in the present instance a peripheral portion- 2, carrying the gearteeth, side plates 3, between which the major portion of the coinpensatinggearing isinclosed, and'a divided hub 4, mounted loosely on the bearing or support of the main gearwheel, so that the latter is free to turn thereon.

5 indicates a shaft or axle-in the present instance a counter-shafthaving at one end thereof a pinion 6, by. means of which one of the driving-wheels of the traction-engine is actuated. Upon this counter-shaft is loosely mounted a sleeve 7 ,which has connected therewith a pinion 8, by means of which the other driving-wheel of the traction-engine is actuated. The sleeve 7 has formed on or secured .by means of which it is accommodated.

. toiitsiunerend a gear 9, located within the Be it known that I, EDWARD HUBER, a citispace between the side plates 3 of the main driving-gear. 10 indicates a second sleeve, secured on the shaft 5 and carrying or having formed thereon a second gear 1] alsolocated 'within the space between the plates 3 and immediately adjacent to the gear 9. The two gears Qand .11 are of equal diameter and have the same number of teeth. The two sleeves 7 and 10 form the bearing or support upon which the divided hub 4 of the main gear rotates.

12 indicates a pinion having journals 13, mounted in suitable bearings carried by the main gear-wheel. In the present instance I have shown one of the bearings, 14, as carried by one of the side plates 3, while the other bearing, 15, is carried 'by a bracket 16, secured to the other side plate, which is provided with an aperture 17 through which the pinion 12 extends. The pinion 12 is a double pinion or it may be formed of two pinions of equal dimensions united so as to rotate in unison, and its inner portion meshes with the gear-wheel 9. Its outer portion meshes with one member of a second double pinion 18, having journals 19 with bearings 20 and 21 in the side plate 3 and bracket 16, respectively. This double pinion 18 comprises a member 22, with which the pinion 12 meshes, and a member 23, which meshes with the gear 1l,the two beingseparatedbyacut-awayspace or circumferential groove 24, into which the peripheral portion of the gear 9 extends and The pinion 18 might of course be composed of or considered as-two pinions so united as to rotate in unison and suitably spaced apart to receive between them the 'gear 9. The two members 22 and 23 of the double pinion 18 are'of the same size and also of the same size as the double pinion 12. PreferablyI employ two sets of these systems of pinions, arranged diametrically opposite each other, as shown in Fig. 1 and as set forth in Letters Patent.

In practice it has been found by experience that where gearing of the type set forth in my said prior Letters Patent is employed in which more power is transmitted to one driving-wheel than to the other it will frequently occur that the wheel receiving more power my said prior will slip or rotate freely, while the other wheel will remain stationary and not rotate at all. This will occur most frequently when the Wheel having more power gets into a mudhole or other slippery depression. By reason of the construction which I have described equal power is imparted to both drivingwheels, so that there is no tendency on the part of one wheel to slip or rotate freely by reason of any greater amount of power being transmitted to it than to the other, while at the same time the wheels are free to rotate to different extents in passing around curves or the like. It will further be observed that by the construction which I have devised, in which one of the double pinions extends laterally beyond the inclosed gears, while the other double pinion is composed of two separated parts having an intervening space to accommodate one of the inclosed gears, I am enabled to make the inclosed gears of the same diameter and number of teeth and also to obtain a similar correspondence in the size of the pinions.

It is obvious that various modifications in the details of construction may be made without departing from the principle of my invention. For instance, although I have shown myimproved gearing as arranged to drive the driving-wheels of the engine through the medium of a counter-shaft it is obvious that the driving-wheels may be directly actuated, as in my prior Letters Patent hereinbefore referred to. Various other modifications will readily suggest themselves, and I therefore do not wish to be understood as limiting myself to the precise details of construction hereinbefore described, and shown in the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a compensating gear, of a loosely-mounted main driving gearwheel, two gear-wheels of equal size mounted side by side in immediate proximity to each other and adapted to be operatively connected with the two driving-wheels of a traction-engine, respectively, a double pinion carried by the main driving-wheel gear, meshing with one of the other gears and extending laterally beyond the same, and a second double pinion composed of two separated members having an intervening space, one of said memhers meshing with the first-mentioned double pinion, the other member meshing with the second of the two gears of equal size, and the first of said two gears extendinginto the space between the two members,substantially as described.

2. The combination, in a compensating gear, of a loosely-mounted main driving gearwheel comprising a toothed annular portion and side plates,apertured as described,brackets mounted on one of said side plates, two gear-wheels of equal size mounted side by side in immediate proximity to each other between the side plates and adapted to be operatively connected with the two drivingwheels of a traction-engine, respectively, and

diametrically opposite systems of pinions journaled in the side plates and brackets of the main driving gear-wheel near its periphery, each system consisting of a double pinion meshing with one of the inclosed gears and extending laterally beyond the same, and a second double pinion composed of two separated members having an intervening space, one of said members meshing with the firstmentioned double pinion, the other member meshing with the second of the inclosed gears, and the first of said gears extending into the space between the two members, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD HUBER. Witnesses:
