IMPROVEMENTl IN PLATFORM HORSE-POWERS.

YThe Schedule referredto in these Letters Patent and part f "che same.

I, FRANK J. CULVER, of Hartforthinthe county of Windsor and State of Vermont, have invented certain Improvements in `Platform Horse-Powers, of which the following is a specification. i

i I Nature mul'O-bject ofthe Invention.,A

The nature and' object of this invention is the co'n struction of an improved platform, horse-power, said which insure greater durability,strength, efciency, andreliability to the machine than the ordinary kind possesses.

In the drawingy v Figure l shows a perspective view of the improved platform horse-powm'.v l

Figure .2 exhibits a top view of' the outer and innel'. rings ot' the angle-irons A A A, in connection witlrthe radial plank pieces B B B. y

Figure 3 represents a sectional view ofthe grooved, broad-faced.traveling roll resting on the inverted T- rail G below -aud on thc ring-plate D under the platform above. v

The new features introduced by this invention arc- Fst, an outer and inner rim of angle-iron, into which are set and bolted thereto and therein a series ot' radial pieces ot' plank forming the platform or por- Second, a series of grooved, broad-faced traveling rolls ruiming on a circular inverted T-rail, while a` ring-plate or metallic vcircle fastened to and beneath said platform runs on said rolls. These grooved, broad-faced traveling rolls afford special and peculiar advantages to this machine over that of others, as they allow a double bearing from Vthe platform circular plate, while there is but a single one upon the rail; they will serve to make the machine pelfectly self-adjusting; will save much friction and do away with the necessity ot' a turned track,

`such an arrangement removing the objections frequently urged' against the nngrooved, narrow-faced,

ordinary traveling rolls. The angle-irons vaforesaid, with the radial pieces set therein, as aforesaid, together make a complete plat- 'form ot' great durability and strength, which lwill-not warp and thereby disarrange the regular and proper action-of the machine, as the angle-irons keep said combined radial pieces true aud eren in position.

I am aware that what are called platform-horsepowers have been long known and used, and, therefore7 I do not claim such broadly; but i that I do claim isy A thorse-power, improved by having a platform made as aforesaid, and mounted on rolls, constructed as heretofore described.
