SPECIFICATION forming part of Letters Patent No. 429,382, dated June 3, 1890.

Application filed June 21, 1889. Serial No. 315,117. (No model.)

To all whom it may concern.-

Be it known that we, OSCAR JOHNSON, of Lindsborg, in the county of McPherson and State of Kansas, and New A. HOLTMAN, of Smolan, in the county of Saline and State of Kansas, have invented a new and useful Improvement in Horse-Power Apparatus, of

which the following is a full, clear, and exact description.

Our invention relates to an improvement in horse-power apparatus; and the object of the invention is to economize in power and attain better results than heretofore; also, to provide a means whereby the team may be attached within the circle of the driving-belt and near the outer end of the lever-arm of the apparatus.

A further object of the invention is to provide an apparatus of simple and durable construction, and capable of being readily transported from place to place.

The invention consists in the novel construction and combination ofthe several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the machine. Fig. 2 is a bottom plan View of the same. Fig. 3 is a central vertical section. Fig. 4 is a side elevation. Fig. 5 is a perspective detail view of one of the lever-arms adapted to receive a cable or chain. Fig. 6 is a perspective view of a modification of the lever-arms, adapted specially for use in connection with a flat belt; and Fig. 7 is a perspective view of the endless-band-supporting frame.

- The frame 10 of the machine, which constitutes the base thereof and which is formed with vertical side walls 10, as shown,is preferably made rectangular, and supported upon axles 11, carrying at their outer ends suitable road-wheels 12. The frame is provided, preferably, at or near the upper surface with a series of transverse bars or beams 18, a longitudinal tie-beam 14, and a central transverse bar or beam 15, secured to the frame at or near the bottom thereof. This lower central transverse bar or beam 15 is immediately belowa central upper bar or beam 16, the extremities of which latter bar or beam are made to project horizontally beyond the side walls 1O" of the frame or base, and the said extremities are bent upward and inward to form guideways 17, as best illustrated in Fig. 3.

Upon the base or frame 10 a circular platform 18 is held to revolve, comprising a hubsection A, a felly-section B, and spokes 0, connecting the two sections, as illustrated in Fig. 1. The felly-section B is provided upon the inner face with a downwardly-extending annular flange 19, and when the platform is placed upon the base the diameter of ,the felly-section is such that it will pass beneath the guideways 17 of the central cross bar or beam 16 of the frame sufficiently to be guided thereby as the platform revolves. To further guide the platform in its revolution a series of horizontally-located friction-rollers 20 is pivoted upon arms 21, attached to the cross bars or beams of the frame, which frictionrollers 20 contact with the inner face of the platform-flange 19, as is also best shown in ly-extending-sleeve, through which sleeve 1 and the hub a vertical shaft 24 is carried downward, the lower end whereof is pivoted in the lower brace bar or beam 15 of the base, the upper end of the said shaft being preferably provided with a hand-wheel 24 or equivalent device to facilitate the revolution of the I shaft. This shaft serves as a center upon which the platform revolves, and is also adapted for use in breaking or stopping the revolution of the platform. To that end ears or lugs 25 are inwardly projected from the cross bars or beams 13 of the base or frame, 10-

cated at each side of the center thereof, as best illustrated in Fig. 2, and upon each lug or car 25 a bracket arm or lever 26 is fulcrumed, the outer end of each of which levers is made cylindrical'to firmly contact with the inner surface of the platform-flange 19. The inner extremities of each of the bracket arms or levers are connected by chains 27, cables, or their equivalent, with the vertical brakeshaft 24, as best shown in Figs. 2 and 3.

It will be readily observed that when the shaft 24 is turned to wind the chains 27 thereon the inner extremities of the bracket arms or levers are carried in direction of the shaft and their outer extremities are made to brake upon the flange 19 of the platform, thereby stopping or materially assisting in stopping the revolution of the latter.

From the hub-section B of the platform a series of lever-arms 28 are made to radiate, which arms are preferably strapped to the felly-section B, as shown in Fig. 1. These arms are preferably of equal length, and their outer extremities are bifurcated, as shown at 29, in Fig. 5, when a chain or cable is to be used in connection with the apparatus. hen the arms are thus bifurcated, the members are preferably curved vertically in opposite directions, and each member, and likewise a portion of the body of the extremity, are vertically slotted, as shown at 30 in said Fig. 5, and in the slotted portion of the upper member of the bifurcated arms a tension or lock latch is fulcrumed, having a reduced lower end, which lower end extends downward through the slot in the lower member of the lever-arm. The upper extremity of the tension-latch is provided with an attached weight 32, whereby the lower reduced portion 31 of the latch is made to normally assume a downward and outward inclination, and a head 32 is formed upon the outer edge of the latch, adapted to clamp the chain or cable to the arms. A

The several lever-arms radiating from the platform are usually connected by a series of links 33, the ends of which links are pivotally attached by a pin or otherwise to the upper surface of each lever-arm. The driving cable or chain 34 is endless, and is made to pass between the members of the bifurcated end of each of the lever-arms 28 and contact with the reduced section of the latch 31, to be clamped thereby to the arms. The driving chain or cable is then carried over a l10llZO11 tal roller 35, journaled in a suitable frame 36, located in front of the apparatus, and around a perpendicular roller 37, also journaled in the said frame 36,-immediately in front of the horizontal roller 35, as best illustrated in Fig. 7, or the said cable may be carried over a vertical drive-shaft, if desired, to rotate the latter. The upper portion of this frame 36 when used is preferably hinged as shown in dotted lines in the said figure, whereby the perpendicular roller, one end of which is journaled in the hinged upper end, may be readily re moved when the said end is thrown back. The chain belt or cable is likewise usually made to pass over a suitable driving-pulley 38, fast upon the shaft 39, journaled in a second frame 40, as shown in Fig. 1, when the frame 36, or vertical shaft above referred to, is employed. This shaft 39, which may be called a drive-shaft, may be belted to a crankshaft 41 or other form of shaft, in which event the power is taken from the latter or second shaft. Any suitable form of gearing may be employed to multiply or otherwise regulate the speed of the drive-shaft when occasion may demand, and if in practice it is found desirable the cable may be carried direct to the driving apparatus contained in the frame 40, and said driving apparatus may be substituted by any other equivalent device, and therefore we desire it to be distinctly understood that the manner of conducting the belt or cable after it leaves the apparatus and the application to the machine to be driven may be changed or varied without departing from the spirit of the invention.

In the event that a flat belt is employed in connection with the apparatus the extremities of the lever-arms 28 may be shaped as illustrated in Fig. 6, in which it will be ob served that a rectangular bar 42 is secured to the outer end of each of the lever-arms, ex-

tending vertically above and below the latter, and the upper and lower ends of said bars are carried upward parallel and at a right angle to the body of the bar. The friction or lock latch or its equivalent is, however, preferred. To one of the lever-arms 28, between the outer extremities of said arms and the platform, an evener D is pivoted, to which the team or teams are to be attached. This evener is preferably made in the form of a figure 4, as illustrated at 43, the upper portion 50 of the figure being pivoted to the lever-arm, and the doubletree or singletree 44 pivotally attached to the lower end 51 of the figure by means of a connecting-rod 45, the said rod being preferably rigidly secured to the doubletree.

The draft is equalized through the medium of a series of links 46, hinged or pivoted together at their extremities, forming a chain crossing the arms and surrounding the wheel or platform to which the arms are attached, each link being pivotally attached at one extremity to a rod or bar 46, which rods or bars are pivoted at their other end to the lower angled portion 52 of one of the figures forming the evener 43, as best shown in Fig. 1. By locating the team thus between the revolving platform and the outer extremity of the lever-arm and within the line of belt or IIO cable we obtain better results than heretofore V shown in Fig. 5, and said belt or cable has been connected with the machine to be driven, the tension of the belt or cable will force the lower reduced end of the latch inwardin the arm, and thereby cause the head of the latch to forcibly contact with the outer face of the belt or cable, and bind the latter firmly between the member of the bifurcated extremities of the arms. When the belt or cable has any of the arms, the weight upon the latch automatically forces the lower end outward to its normal position, concealing the latch-head, to be again engaged by the belt or cable as the main frame revolves.

Having thus described our invention, we

claim as new and desire to secure by Letters Patent 1. The combination, with the main frame having vertical side walls. 10, a revolving platform mounted over said side walls, an operating shaft or bar mounted in said frame and projected above the revolving platform, of a series of brake-levers pivoted to said revolving platform provided with bearing-faces engaging the vertical side walls 10 of the frame 10, and cable-connections between one end of said levers and the said operating-bar,

substantially as and for the purpose described.

latches, of a series of equalizing-links, of draft attachments pivoted to said radial arms and connected to the equalizing-links, said attachments formed essentially of the shape of a figure 4, having its pivot at its portion 50, a draft-bar 45 connected to its foot or stem 51, said equalizing-links 46 connected to the point 52 of said attachment, all arranged substantially as and for the purpose described.

3. In a horse-power apparatus, the combination of a revoluble platform'or table provided with a series of radial arms, each havingbifurcated ends 29 and 30, provided with vertical slots, a lock latch 31, pivoted in the upper slotted end 29, having a rearward weighted extension, a downwardly-extending arm projected through the lower slotted arm 30, said arm 31, normally projected beyond the base of the bifurcated arms and having a projecting head 32 all arranged whereby the pressure of the cable against the arm 31 will cause said head 32 to bind against the cable, as and for the purpose specified.
