TRACTION-WHEEL.
SPECIFICATION forming part of Letters Patent No. 268,609, dated December 5, 1882. I Application filed August 21, 1882. (No model.)
To all whom it may concern:
Be it known that I, EDGAR M. BIRDSALL, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful"Improvements 'in Traction-Wheels for Traction-Engines, of which the following is a specification reference being had to the accompanying drawings. 7
The general object of my invention is to improve the construction of traction-wheels for traction-engines.
In the accompanying drawings, illustrating .my improvements, Figure 1 is a side elevation of my improved traction-wheel. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical central section of the same. Fig. 4 is a formal modification of the same as to the periphery of the wheel. Figs. 1 and 2 show in side and front elevation a special construction of the most approved form of the periphery or traction-face of the wheel. Fig. 3 is a detached segment for forming part of the traction-face of the wheel, and Figs. 4 and 5 detail sectional views of the same.
Referring to the letters upon the drawings, A indicates the traction-wheel, B its hub, and G the axle.
In constructing my wheel I first form the body or spider of the wheel of wrought-metal bars D and bolt them together firmly in any suitable manner or number, but preferably, as
illustrated, to constitute a strong wrought metal bracing, with a central opening, E, to receive the hub. I prefer to employ at least two of these spiders in each wheel, and I connect them, by means of bolts or in any suitable manner, to two angle-bar rims, F, having annular grooves in their peripheries, which are afterward united in any of the ways illustrated in the drawings, but preferably, as illustrated in Figs. 1 and 2 by means of either wrought or cast bands or segments G, firmly bolted to the adjacent sides of the rims. These bands or segments, as will be observed, are provided with apertures H and spurs or projections I, whereby a portion of the ground covered by the tread of the wheel will be penetrated, so as to compact the surrounding ground, and another portion will be allowed to press up through the apertures, thus giving a very strong and reliable hold upon the ground, which will avoid danger of slipping of the wheel.
greatest liability to slip.
To form my improved hub I make castings K exactly alike, except that they are adapted to face in opposite directions. These castings consist of the tubular part L, the plate part M, the flange N, and the webs or braces 0. These castings are placed within the central hub-aperture of the wheel, so that the flange N will bear hard against the surrounding bars bounding the hub-aperture. The flanges N are preferably inclined slightlyupon their-outer surfaces, so that they will .wedge firmly into place against the bars D. Two of these cast ings, being properly placed, are then secured in any suitable way by bolts P. I thus form a very light, strong, and durable tractionwheel, capable of reliable service in all situations.
Having thus described my improvements, what I claim as new, and desire to secure by Letters Patent of the United States, is
1. The combination of the wrought-metal spider or body of a traction-wheel with an angle-bar rim having an annular groove in its periphery, substantially as set forth.
2. The combination of the angle-bar rims, having annular grooves in their peripheries, with the bands or segments Gr,'substantially as set forth.
3. The improved hub herein described, composed of castings K, comprising the tubularaxle-bearing L, the face-plate M, and webs O,
substantially as set forth.
4. The combination of the hub composed of the two castings K, comprising the tubular axle-bearin g L, the face-plate M, and webs O, with the wrought-metal spider or body of the wheel, substantially as set forth.
In testimony whereof I havehereunto subscribed my name this l0th day of August, A... D. 1882. EDGAR M. BIRDSALL.
