SPECIFICATION formingpart of Letters Patent No. 732,327, dated June 30, 1903.

Application filed September 13, 1902. Serial No. 123,263. 1 (No model.)

To aZZ whom it may concern.-

Be it known that I, HUGH L. WARNER, of Dayton, in the county of Montgomery and State of Ohio, have invented a new and use- The objects of my improvements are, first,

to produce a compensating gearin which the various parts that are subject to wear can be made independent of each other; second, to produce a compensating, gear that can be made and sold as a perfect compensating gear independent of how it is to be driven, whether by belt, chain, spur-gear, or otherwise; third, to produce a compensating gear that when fitted with such driver it need be nothing more than a rim attached to the outer periphery of my gear by any suitable means; fourth, to produce a compensating gear so constructed that the usual driver will readily interchange from'one side to the other; fifth,

. to produce a compensating gear in which the driver, being a separate piece and wearing out much faster than any other part, may be V taken off and a new one replaced without opening the working parts; sixth, to produce a compensating gear in which while in actual use the small pinions and their axles, which are liable to strains, can be taken out andexamined or replaced independent of each other and independent of any other part, so as not to remove the entire gear for such purposes, and, seventh, to produce a compensatiug gear that has the strongest construction, most perfect alinement, most durable in wear, and economical to manufacture, all because of the one-piece frame, in which the pinions are independently set, perfectly axle, or in various otherways. 2 the spur-gear F fastened on the solid axle G by the small key g, and the spur-gear E housed, properly separated, and self-contained and which also carries the two large spur-gears in perfect alinement and their retainers; and to accomplish these objects my compensating gear'consists of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a face view of my compensating gear, the axles removed, Fig. 2 is asectional view taken, respectively, on a lineA B, Fig. 1, the axles being shown in position. Fig. 3 is a part of the driving member, the remainder broken away. Fig. 4 is a sectional view taken, respectively, on a line E F, Fig. 1, which shows how the pinions and their bearing-bolts are mounted in the frame. Fig. 5 is a section of the frame only, taken, respectively, on a liueAG, Fig. 1, all partsremoved. Fig. 6 is a face view of the frame only, all parts removed, showing the opening for the large spur-gear and openings for three pinions, a duplicate set of openings being in the opposite face. Fig. 7 is a face view of one of the retainers. Fig. 8 is a view of one pair ofpinions and the two large spur-gears as they are in the frame. Fig. 9 is a side View of a pinion bearing-bolt, the small end shown in section through center, so the internal thread can be seen.

Similarletters refertosimilarpartsthroughout the several views.

My compensating gear consists, essentially,

of a frame 13, one or more pairs of pinions P, spur-gears E and F, bolts J, and retainers C, which when assembled may be mountedon two abutting axles, one spur-gear on each I show in'Fig.

vided with outwardly-extending hubs e and f which may be used to fasten to. The outer radial face of the rim 0 which has spur-teeth 0 comes flush with the outer face of the web 0. (See Fig. 2.)

The pinions L and M, arranged in pairs, are usually equally spaced around the spurgears. The entire length of a single pinion is not quite as long as the width of the face of a spur-gear plus the space between the spur-gears. (See Fig. 8) The pinions of each pair engage each other and engage the spurgears, respectively.

The pinion bearing-bolt J (see Fig. 9) is preferably made of a single piece and has a large head j, with an extension of flangej which when in position, as in Fig. 2, performs three duties at once. First, it forms a dust-proof cover for the pinion L and holds it in place against the bottom m; second, it forms a rigid support for the outer end of said pinion, and, third, it holds the retainer 0 in place. The outer fiangej fits in against the shoulder b Fig. 5, and prevents the bolt going in too far, so as to bind the pinion endwise. The small end of the boltJ is provided with means for engaging the frame and for being locked fast. Said means is preferably the external and internal thread and 0, one thread being a coarse right-hand and the other a fine left-hand or otherwise.

The retainers C and D, Fig. 2, hold the spur-gears E and F in place, said retainers being held in place by a series of bolt-heads J, which engage the niches c of the retainer 0. (See Fig. 7.) The retainer 0 has a small flange 0' around the outer periphery, which fits against the shoulder Z)", Fig. 5, and prevents it from going in too far and binding the large spur-gears.

The driving member A, which in the drawings is a sprocket-rim, (and which in practice may be something else,) is provided with teeth a on its outer periphery for engaging a driving-chain, and inwardly-projecting lugs a having counterbored holes a, adapted to receive the screws a and forms a means for fastening the driver A on the frame B.

The frame B consists of three annular bands 12*, b, and b fastened together as follows: Z) is of a smaller diameter than 17 and is placed within it and joined to it by webs or spokes b and pinion-cases I2 and 6 and within b is the third and smallest band I), fastened to the band 12 by the web 19 as seen in Figs. 1, 2, 5, and 6. The band b is not so wide as the two outer bands I) and b and has flanges b 'and I) turned out on its bearing-box for the hubs e and f of the two spur-gears. The outer band I) has a series of inwardly-projecting lugs a on one edge and a duplicate series at on the opposite edge. These lugs are preferably threaded to receive the screw a.

My compensating gear when assembled is very light and compact. As will be seen in Figs. 1 and 2, the adjacent ends of the hubs 6 and f are in contact, while the outer periphery of said hubs fit snugly into the central bearing-box I9 The inner radial faces of the spur-gear webs form bearings against the outer faces of the flanges b and b and the overhanging rims c are supported by the outer peripheries of the flanges b and b. The spur-gears are held in place by the retainers and the retainers by the pinion-bearing'bolt heads. The hollow spaces S and S are oil-chambers for grease or Vaseline.

The peculiar construction of the pinioncases I) and Z1 is such that with each pair of pinions in order to engage each other they have to be inserted from opposite faces of the frame and run in individual cells almost completely incased and on independent bearingbolts. Thus I am enabled to assemble my compensating gear independent of the driving'attachment.

Referring to Figs. 1 and 2, it is plain to be seen that if I want to remove an individual pinion or bearing-bolt I need only to remove the locking-screw O in the small end of the pinion bearing-bolt, removing the bolt and pinion, and if I wish to examine the large spur-gears I need only remove the pinion bearing-bolts and the retainers, and the whole internal mechanism is exposed and may be withdrawn. Both faces of the frame B being exactly alike, it is plain to be seen that the parts will interchange.

I am aware that prior to my invention coinpensating gears have been made in which a pair of spur-gears placed side by side and mounted on axles were respectively engaged by a pair of spur-pinions having hubs and said pinions engaging each other.

I therefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is-
