HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 415,215, dated November 19, 1889.

Application filed July 29, 1889. $erial No. 319,055. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM M. l\IILROY,'

a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented a new and useful Improvement in- Horse-Powers, of which the following is a specification.

and claimed.

The primary object of the invention is the.

production of simple and inexpensive horsepower apparatus adapted to be readily at tached to and to coact with a fixed upright wooden post, and especially with the kingpost of a style of barns common in some sec tions of the country. The objects of its respective combinations are, first, to provide the master-wheel with a steady frictionless bearing requiring very little lubrication; second, to so construct said bearing as to facilitate assembling the parts or their separation, should occasion arise third, to guard the spur-gearing against injury to attendants and against accidental obstruction, and, fourth, to facilitate safely attaching a shield to the supporting-post for the purposes last named.

Two sheets of drawings accompany this specification as part thereof.

Figure 1 of the drawings is an elevation of a horse-power constructed according to this invention. Fig. 2 is a plan of the parts at and below the section-line 2 2, Fig. 1. Fig. 3 is a sectional perspective view showing details of the shield-attaching devices. Fig. 4 represents a half-plan of the parts at and below the section-line 4, Fig. 1. Fig. 5 represents a vertical section of the same portion of the apparatus 011 the line 5 5, Fig. I. Fig. 6 represents an elevation of the bearing part before the master-wheel is lowered into position thereon; and Figs. 7 and 8 represent inverted plans of the bearing part and of the master wheel, respectively, illustrating a modification. Figs. 3 to 6, inclusive, are enlarged three diameters from Figs. 1 and 2.

Like letters of reference indicate corresponding parts in the several figures.

In carrying this invention into efiect I provide a fixed upright wooden post A with a cast-iron bearing part B, having an angular bore, and which may be conveniently cast in two or three sizes as to this bore, which is tightly fitted to the post by hewing the sides of the latter, if need be. Said bearing part B is constructed with a lower portion a, 0011- formed to the bore, and provided with screwholes, through which screws 3, Figs. 5 and 6, are driven horizontally into the post, so as to fasten the bearing part securely in its position. A circumferential horizontal trackflange b is next above said portion a, and at top there is a cylindrical portion 0. The periphery of the latter is recessed at three or more points, preferably four, for the reception of anti-friction rollers r, w ich project slightly beyond its circle, and he bearing part is drilled vertically at coincident points for the reception of spindle-rods the horizontal upper ends of which carry a second set of rollers 0- while their lower ends are screw-threaded and provided with adjusting nuts or below the flange b. The spindle-rods pass through and pivot said rollers 7' as well as said rollers 4 and ordinarily an occasional lubrication of these rods will suffice for the whole of the bearing part. Notched bolsters b are formed on the upper end of the bearing part B to coact with said upper ends of the spindle-rods s in their effective positions, as shown in Figs. 4 and 5. When the nuts 11 are turned back, the spindle-rods are readi y disengaged from the bolsters b so as to throw their rollers 1' within the circle of the bearing portion 0, as shown in Fig. 6.

With the bearing part made ready, as shown in Fig. 6, a master-wheel C is lowered into position thereon, the bore and upper end of its hub at being adapted to coact with said rollers r and r respectively, when the latter are turn ed into position above it and drawn down by the nuts n,which is readily effected. The master-wheel is thus kept in place. The lower end of its hub d is recessed and provided within its recesses with rollers r Figs. 4: and 5, whichv coact with thetop of the track-flange b. The spindles 5 Fig. 5, of said rollers r may be lubricated, should they require it, by applying oil to the sides of the rollers, so as to be carried up to the spindles, or in any approved way.

The bottom of the master-wheel C is pro- V band-pulley as, for example, from which.

vided with one or more, and preferably two, radial sockets e adjoining its hub d, and with stirrups f in line therewith, the latter providedwith horizontal holes at different heights for the reception of the inner ends of draftlevers or sweeps D and of pins 19, whereby the sweeps are removably fastened in place with a convenient provision for raising or,

lowering their outer ends to suit the horses.

Spur-gearing for transmitting motion from the master-wheel 0 preferably comprises internal teeth t, formed in the master-wheel at 'top, so that its rim is smooth, and each tooth may be united with the body of the wheel at end and bottom. The bottoms of the corresponding interdental spaces are beveled, as shown in Fig. 5, so as not to accumulate dust. A spur-wheel it, fast on the lower end of a vertical shaft E, meshes with said internal teeth of the master-wheel, and the upper end of said shaft is connected by bevel-gears o to with a horizontal shaft F, which carries a power may be readily taken for any purpose for which it may be needed and suited. Such transmitting-shafts E F are conveniently supported by strap-bearings y 2, two

patterns of which may suffice, the same tobe made of wrought-iron and perforated for screws, which are driven therethrough into the post A and an overhead beam H, to coincident corners of which the respective bearings are fitted, as indicated in Fig. 4. Brasses b may be embraced by the respective strapbearings, as indicated in Fig. 4, and supplemental collars c, Fig. 1, may coact therewith as thrust-shoulders where gear-hubs cannot be so utilized.

A shield I, Figs. 1, 2, and 3, surrounds the post A immediately above the master-wheel to mask the main gearing. With peripheral or crown teeth on the master-wheel a shield of greater diameter and with a depending marginal rim would be'required. In connection with the internally-toothed master-wheel having a smooth rim, as aforesaid, a superposed shield of no greater diameter than the masterwheel suffices. This shield is conveniently formed in four sheet-metal sections attached to the post by hooks h and tie-rods and staples 11 71 the stems of the hooks h and the staples i being driven into the several sides of the post, While the shield-sections have the said rods coupled to them and are provided with holes h, fitted to pivoted heads M, Fig. 3, on the hooks h, so that said heads pass through said holes in one position and fasten the shield-sections in place by being turned at right angles, as illustrated by Fig. 3. A pair of such hooks to each shield-section keep the same from tilting, and thus'keep the joints in the shieldsufficientlyclose, while the shield is very readily attached and removed at will.

The whole of the apparatus is designed to be put together and used with the aid of simple instructions by ordinary farm-laborers,

in place, as in Fig. 6.

and is epecially intended, as aforesaid, for use in barns where a king-post supported at bottom on a flat stone 3, Fig. 1,is adapted to serve as the said post A and the main crossbeam which rests thereon will serve as the said overhead beam H. -By propping the latter, removing the stone 3, and excavating a very little,if need be, under the kin g-post, the

may be slipped under the post and lifted upward around the same, the former being then propped up until the bearing part is fastened The stone 8 having been replaced and the props of the overhead beam removed, the weight of the superposed beam and floor, with the load on the latter, keeps the post A in its upright position with ample security.

For use where it is not convenient or is not considered safe to get beneath the post sectional bearing parts B and master-wheels (1 may be constructed as illustrated by Figs. 7 and 8. In each of these figures, j represents a diametral joint tightened by screw-bolts in an ordinary way. I

Details which have not been specified may be of any approved description, and I do not limit my several claims to details which are not stated in them respectively.

Having thus described the said horse-power, I claim as my invention and desire to patent under this specification- 1. In combination with a fixed upright wooden post and the master-wheel of a horsepower surrounding the same and having the bottom of its hub provided with anti-friction rollers, an interposed bearing part having a bore fitted to the post, a perforated lower portion through which screws are driven into the post, and a circumferential track-flange above said perforated portion and provided with anti-friction rollers within and above the hub of the master-wheel, those on the bottom of the latter coacting with said track-flange, substantially as hereinbefore specified.

2. In combination with a fixed upright post and a master-wheel surrounding the same, an interposed bearing part made fast on the post and having its upright portion provided with peripheral rollers t0 coact with the bore of the hub of the master-wheel, rollers at top to coaet with the top of the hub, spindle-rods common to both sets of rollers, having horizontal upper ends and screw-threaded lower ends, notched bolsters which engage with said upper ends in their working positions, and screw-nuts on said lower ends of the spindlerods, substantially as hereinbefore specified.

3; In combination with a fixed upright post, a master-wheel, its bearing, and asuperposed shield surrounding the post and supported thereby, and spur-gearing for transmitting motion'from the master-wheel, said masterwheel being constructed with internal teeth at top as part of said gearing and having a smooth rim, whereby a shield of no greater diameter than the master-wheel suffices to 75 master-wheel O and then the bearing part B"
