LEWIS W. HAS SELMAN, OF INDIANAPOLIS, INDIANA.

PORTABLE ENGINE.

SPECIFICATION forming part of Letters Patent No. 224,427, dated February 10, 1880. Am cation filed November 20, 1879.

To'all whom it may concern Be it known that I, Lnwrs W. HASSELMAN, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Wheel Attachnients for Portable Engines, of which the following is a specification.

Reference is bad to the accompanying drawings, which are made part hereof, and on which similar letters of reference indicate similar parts.

Figure 1 is a side elevation of a portable engine having my improved attachment. Fig. 2 is adetailed section, on an enlarged scale, showing the attachment more clearly.

In said drawings the portion marked A represents the boiler of an ordinary portable engine; B, the hind carrier-wheels; G, the front carrierrwhecls; D, the front axle-tree; E, a horn-like projection, which connects the boiler to the axle-tree. and which is the attachment that forms the principal element of myinvention F, the main drivingbelt pulley; G, the shaft to said pulley; and H, lugs attached to the front end of the boiler, which form the bearings for said shaft.

The object of my said invention is to provide ameans which will admit of the drivewheel being lowered, so that its lower side will be considerably below the upper side of the carrier-wheel nearest it, and at the same time allow the latter to circle freely about the former. This I accomplish by running the shaft for the drive-wheel across the front end of the boiler and making the position of the king-bolt vertically underneath said shaft, or nearly so, by means of a forwardly-projecting attachment fastened to the bottom of the boiler.

Heretofore the attachment employed in this connection has projected vertically downward from the bottom of the boiler rather than forwardly, as does mine. With such an attachment, while the drive-Wheel could occupy the same position shown in my drawings, the carrier-wheels could not turn to he extent to which they should without striking it. To obviate this disadvantage some engines have been made with the drive-wheel shaft placed over the top of the boiler; but as such a location makes it necessary to also raise the steamchest and cylinder, thus making the engine top-heavy, it has made that steadiness of motion which all engines should have difficult to obtain, and made them more liable to topple over when passing over uneven ground. Such an attachment of the shaft and cylinder is more likely to wrench or strain the boiler and cause it to leak than when they are attached to the sides and lower down.

As hereinbefore indicated, I am aware that engines have been constructed with the drivewheel shaft vertically above the front axle, and probably more engines are constructed with the peripheries of the drivewheel and carrier-wheel passing each other than in any other way, as it is very desirable that they should. I have, however, never seen the former feature combined with the latter, which it must be, in order to come within the scope of my invention or to accomplish its object.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the wheel F, mounted on a shaft, G, running in front of the boiler A, and mounted upon bearings attached to the sides thereof, with the wheel 0, mounted upon the axle D, which is pivoted to the forwardlyprojecting attachment E upon the under side of the boiler when the pivot-point of the axle D is vertically beneath the shaft G and the peripheries of the wheels F and 0 pass each other, all substantially as shown and described, and for the purpose specified.

2. The combination of the wheel F, shaft Gr, wheel 0, and axle D, the shaft G being attached to bearings attached to the sides of the boiler at a point below its top, and the axle D being pivoted at a point vertically below said shaft, while the peripheries of the wheels pass each other, all substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 10th day of November, A. D. 1879.

LEWIS W. HASSELMAN.
