GEARIN'G.

To all whom it may concern:

Be it known that I, ANDREW J. MOLEN- DON, a citizen of the United States, residing at Edith, in the county of Coke and State of Texas, have invented a new and useful Gearing, of which the following is a specification.

This invent-ion has reference to horse powers, and is designed to improve the construction thereof and the utilization of the power obtained therefrom.

The objects are to provide a. machine of this type and character from which vary ing rates of speed may be obtained and which may operate through the instrumentality of a horse or like animal or which may be otherwise motor driven.

lVit-h the above and other objects in view, the present invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, specifically claimed and illustrated in the accompanying drawings, wherein,

Figure 1 is a plan view of my power creating device adapted to be operated by a horse. Fig. 2 is a longitudinal section taken along line 22 of Fig. 1. Figs. 3 and 4 are modifications of the driving means showing the provision of a gas engine carried by the sweep.

Reference being had to .the drawings, 1 indicates a circular beam which may rest on or be partly buried in the ground having securely attached to its upper face'the metallic track 2 upon which rotates the supporting wheel 3. This wheel is secured to a shaft 4 which is journaled on and carried by the sweep '5, the outer end of the sweep being thereby supported by the wheel 3 and its inner end by a pillar 6 located at the center of the circle formed by the track. The said inner end of the sweep consists of a pair of arms 7 and 8 extending from and pivotally engaging the pillar 6. The shaft 4 carried by the sweep is journaled in a bearing 9 at the outer end thereof and in the upright portion 10 of the arm 7.

Keyed to the pillar 6 is the inner collar or supporting drum 11 having a casing 12 thereon, access to the said casing being obtained through openings 13 provided in the base and upper plate thereof. Located in spaced relation to this cent-rally located hollow drum are the concentrically disposed bands 14, 15 and 16, respectively, the outer pair of said bands 14 and 15 being con- Specification of Letters Patent.

nected by a series of stub machine bolts 17 in such a manner that they are firmly secured together. At regular intervals about the same there extends from the outer band 14 through the intermediate bands 15 and 16 to the collar 11 the stays 18 which rigidly secure the outer bands 14 and 15 to the collar. A similar construction is prbvided between the drum 11 and the inner band 16, the bolts and stays in conjunction with the bands between which they extend constltuting a pair of concentric horizontally disposed ring gears C and B.

A pair of arms 19 project downward from the under face of the lower arm 8 of the sweep 5, and carry therein a stub shaft 20, said shaft forming a support for a spur gear 21 which engages the machine bolt-s 17 extending from the inner band 16 to the drum 11 and meshes with a similar gear 22 secured to the inner extremity of the shaft 4 which plays in the space between the arms 7 and 8. Thus when the sweep is drawn around the pillar 6 as a center, the wheel 3 will be caused to travel over the track 2 and by its engagement therewith will be rotated. The rotation of the wheel 3 will be transmitted directly to the shaft 4 and from the same to the gear wheels 21 and 22. The inner horizontal gear wheel B is thus set in motion and, consequently, a similar motion is imparted directly to the outer wheel C.

Mounted between the track 2 and the supporting beam 1 is the power transmitting shaft 25 having at its inner extremity the spur gear 26 and at its outer extremity the power pulley (or crank) 27, the latter being of a construction which will permit either a belt or a pitman to be secured thereto. The spur gear 26 engages the machine bolts 17 between the outer bands 14 and 15 and is thereby rotated so as to transmit power through the shaft 25 to the operating pulley 27.

At regular intervals about the periphery of the outer band 14 are located the guide rolls or pulleys 28 mounted in supports 280 and which not only facilitate the rotation of the concentric ring gears B and C, but guide and support the same in a manner which increases the durability and strength of the machine. These rolls, if preferred, may be doubled and secured at each side of the band to prevent any displacement thereof on the pillar 6.

From the foregoing it may be readily seen that upon attaching a horse to the Whittle tree 29 carried on one side of the sweep '5, the sweep may be rotated without weight on the animal owing to the presence of the wheel 3 and track 2, thus rotating the concentrically disposed wheels B and C with the result that the spur gear 26, acting through the shaft 25, will operate the power pulley 27, thus transmitting power by any desired means to the adjacent machinery.

The motive power may be increased, if so desired, as shown in Figs. 3 and 4, by a gear 30, secured on the end of the shaft 4 around the hub of the traction wheel, revolved by meshing with a gear 31 carried on the drive shaft 35 of an engine 32. This engine is supported by a brace or platform 33 rigidly secured to the sweep 5, the said brace being supported at its outer extremity by a roller or similar traction wheel 34, the said traction wheel operating directly in the rear of the large traction wheel 3. Furthermore, it can readily be noticed that by changing the sizes of the gears 21 and 22 the speed at which the concentrically disposed wheels B and C rotate may be controlled, likewise the number of revolutions of the power transmitting shaft.

Horse power machines of this type are commonly employed for driving merry go rounds or other small pieces of machinery, and the construction described avoids the usual objection that the horse in his trip around the circuit must atleast once step over a shaft. The shaft 25 in this device is located practically flush with the surface of the earth, and might even be lower without departing from the spirit of my inven- Copies of this patent may be obtained for five cents each, by addressing the Gommissioner of Patentstion; and yet the sweep 5 is purposely elevated so that the whiflle tree 29 is in convenient position for attachment of the draft animal and his pull thereon has no tendency to lift the wheel 3 off the track. WVith the machine set up and running and connections to the work already established, it frequently happens that the work is increased (as by an excess of patronage of the merry go round) or the horse goes lame, and in such cases it becomes desirable to add power to the strength of the horse or to substitute motive power for his work. The construction illustrated in Figs. 3 and 4: affords means whereby this can be quickly accomplished, for it is only necessary to start the engine 82 and the connections with the work being done need not be interrupted.

Having thus described my invention, what I claim is:

A power transmitter comprising a member rotative in a horizontal plane, gearing carried by the member, a series of concentric circular bands arranged below the gearing, a series of radial bolts connecting the outer bands, a series of similar bolts connecting the inner bands and engaged by the gearing, means extending from the outer to the inner bands for rigidly connecting the parts, and gearing actuated by the outer series of bolts.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
