[iMPRovFEMENT IN l-sloasia-POWERs.Y

-` Specification forming part of Letters Patent No. 35,567, datcdJune l0, 1862...

Be itknown that I, STUART PERRY, of Newf tionhin which- F'gure l representsa perspective view of my horse-power machine.' Figs. 2- and 3 represent detached `portions thereof, to better-illus- ,atrate details not distinctly seen `in Fig. 1. Figs. 4, 5, and 6`1represent a vmodification of -my general "plan of construction, but showing 3a different modeof applying the same. Similar letters of reference, where they ocy cur in the several figures, denote like parts of thehorse-powerin all the drawings. l

Tractioneenter geared horsepowers have long been known, but from defects in theirV construction have not gone into general use. "As heretofore constructed the power derived from this kind of horse-power has been very limited, aud to attempt to increase their power Y y "or speed created either a slip of the tractiony wheel, or else excessive friction, either of which would render the machine impracticable for general purposes; Vbut being satisfied that this kind of horse-power possessed many good qualities-viz., cheapness, simplicity, portability, adaptability to any purpose or any place,

` `easily setup or takendown, and requiring but, little stowage-"room--I determined, if possible, to overcome the-objectionable features of the `machine as heretofore constructed, andhave succeeded in doing so and in producing ahorse-power that is very efficient and very My inventioncons'ists, first, in the kind of l gearing Iuse at the center of the-machine, and

the combination of the same, so as to get up a quickspeed without undue cramping or friction of theseveral moving parts; and, my in.

vention further consists in the manner of uniting the main driving-shaft with the main drivewheel, so that the shaft may vibrate vertically u To enable others skilledin the art to make and use my invention, I will proceedl to de scribe the same with reference to the drawings. l v

A represents a traction-wheel, to whichone end of the shaft B is affixed so as toturn withf the wheel. A The opposite end of said'sha-ft has' ajonrnal, a, Fig. 3, upon it, which turns in a rock-ing journal-box, b, Fig. 2supported upon arms G C, united to an upright or column, D, thatis firmly affixed to the ground or base of the machine, to hold the gearing steady. To the interior or center end of the shaft B there is fastened a hollow or cup-shaped gear-wheel, E, that will slide and work over the rocking journal-boah, so as tobring said box at or near the center of said wheel E, for a purposek that will be hereinafter mentioned. rlhe wheel `E may-have a sleeve, boss, or hub,'c, upon it, projecting from the solid end of the wheel, and by means of thissleeve, boss, or lub it is fastened tothe shaft B. l The gear-wheel E, it will be perceived, has'` square teeth 'or' cogs upon it, and it meshes with and turns a compound square and bevel wheel or pinion, F, that is supported on an axis or shaft, d, Fig. 2, the cogs of the wheel E taking into the square cogs e of the compound pinion F,

while the bevel-cogs f of the pinion F'mesh with-and turn a bevelpinion, g, on top of a shaft, h, that turns in the columnD, the lower end of this shaft h being furnished also with a ybevel-gear, fi, which, through a bevel-pinion, j, ou a horizontal shaft, 7c, gives motionto said shaft Ic; and from this shaft motion may be communicated to any machinery to be driven by the horse-power.

over its natural surface without leveling it down, as the rocking box b will allow the shaft B to'rise and fall without injury to the gearing, because, in theiirst place, considerable motion at the wheel end of the shaft would-beinappreciable at the center or other end,and whatv motion there is at the center is in the n center of the wheel E and simply rocks said wheel without jamming or cramping it with lthe other gear, F. With bevel-gears this could not be done as safely, because theA heels or points of the teeth would have to sustain all the strain and would be liable to injury there- The wheel A may run upon the ground and from. The straight or square gear at the center is much better than the bevel-gear, and, so far as I'can learn, I am the first to introduce square gear at the center of this kind of horsepowers.

The advantage of making the wheel F a compound wheel, instead of two wheels, is this: the tendency of the gear E is to raise up the gear c of the pinion F 5 but this is counteracted by the tendency of the pinion g to force down the partf of the pinion F, and thus they counteract each other and prevent the pin or shaft d from being unevenly worn by extremepressure in one direction only, and prevent undue friction. Ihe uneven wearing of the pin or shaft d may be avoided by turning said pin or shaft in its support on or in the column D and thus make it wear away evenly at least.

I have shown a track for the wheel A to run on, but this, as before stated, is not actually necessary, as it may run upon the ground. If, however, it is preferred to have a track to move it on, then plank, as at G, may be pinned down to the ground, or a continuous circuitous track, H, may be used. The elevations and depressions in the track are designed to show that lthe wheel will surxnount or drop into them without injury to or even cramping the gear at the center. If the traction of the wheel is not sufficient, or if it has a tendency to slip, it may be loaded down to increase the traction by placing weight of any kind upon it, as at m; and a very cheap and economical modev of making the wheel A is to have it cast hollow and have an opening into it, so thatit may be filled with earth to give it weight and be readily emptied when it is to be transported any distance.

In the modification of the above-described construction, as shown in Figs. 4, 5, and 6, the

same letters show the corresponding parts, but differently arranged. In this modification the shaft 7L has at its lower end a erank-wheel, a, to which a pitman, o, is connected, and from this pitman the motion may be communicated to any machinery to be driven by it.

By describing the gear-wheel F as a compound wheel I do not wish to be understood as limiting my invention to the making of the straight and the bevel teeth or cogs in one piece, for it is evident that they may be cut apart or made in two separate parts and still accomplish precisely the same purpose. I prefer to make thiswheel F as shown in the drawings; but it is evident that the straight and bevel portions may be separated and placed on the same journal, d, or indeed, each on its own journal, and effect the same result by an equivalent arrangement of the parts.

Having thus fully described the nature and object of my invention, what I claim therein as new is l. Supporting the end of the shaft B in or near the center of the main drive-wheel E, for the purpose substantially as described.

2. In combination with a main drive-shaft that has upon its outer end a wheel that may run over an uneven track, the hanging of the opposite end in a rocking or pivoted box to yieldv thereto, substantially as described.

3. In combination with the main drive-wheel E and the bevel-pinion g, the compound pinion F, composed partially of square and partially of beveled teeth, substantial] y as and for the purpose set forth.

STUART PERRY.
