IMPROVEMAENT IN RAILWAY CAR-WHEELS.

i Specification forming part of Letters Patent No. 128,939, dated July 16, 1.872.

SPECIFICATION.

Figure l is a view of back face of the wheel Fig. 2, a view of the front face of the same. Fig. 3 is a transverse section in the direction of the line a: .r in Figs. l and 2. Figs. 4, 5, 6, 7, and 8 are detached sections, which will be referred to in the following description.

,Like letters of reference refer to like parts in the several views.

The nature of my improvement relates to making or casting the tire of the wheel with an interior annular web or flange, to give additional strength and firmness to the wheel, and having a recess or space on each side of such web to receive a packing or fllin g of prepared paper or other suitable material for this purpose 5 and anterior to this paper filling or packing are metallic plates, so arranged in relation to the tire, web, and paper filling as to form even or flat faces or covering to the wheel, or nearly so. These parts are connected together by bolts passing through the said web, paper filling, and outside plates; thereby the several parts are firmly and securely united. The hub is made, in a separate piece with a flange or collar, which hubl is firmly fitted into a central bore or opening through the outside plates and paper filling, but leaves a space between the interior flange of the tire and hub, which hub is firmly secured in place by bolts, thus forming the entire wheel, which, by its peuliar construction and arrangement of the parts, renders it strong, safe, and durable, and at the same time givesm a slight easy spring or yielding action to the jars and strains of the track and train, thereby causing the cars to run with more ease and comfort to the traveler,

and with less injury to the track than wheels of the ordinary kind.

It is designed to make the tire A, Figs. 1, 2, and 3, of cast-iron, and to secure Yto such tires the requisite strength without unusualv weight of metal. There is cast or connected with the4 interior face of theV tire an annular flange or web, B, Figs. 3, 4, and 5, Figs. 4 and 5 being views of opposite sides of the tire A and interior flange. this lian ge is a cavity or recess, which is filled up by the paper packing or plates C C', or its equivalent, seen in Fig. 3. This filling or pack! in gof paper prepared for this purpose is closely and securely fitted into each recess. Outside of this lling (l C are plates D D', as seen in Fig. 3, and it will be observed that the hub E, Fig. 8, passes through the bore F, or holes in the fiange B, filling G C', and plates D D. The fiange G of the hub laps upon the plate D, forming the back of the wheel. terior fiange B does not extend to, nor is it in -contact with, the sleeve H of the hub; on the contrary, there is an annular space extend ing around the outside of the sleeve, and the interior edge of the web B, as indicated at I, Fig. 3, while the paper filling C C' is in closev contact with the sleeve, and their peripheries fit closely to the face or sides of the recess at J on each side of the flange B. It is designed to have these packings or fillings to fit tightly around the hub, and into and again st the inner face of the tire, as before noted. The base of the outside plates D D is also made to fit tightly upon the sleeve of the hub, while their circumference is less than that of thecircumferences in which they are respectively placed, as seen at ct a', Fig. 3. Each plate rests upon a shoulder of the said recess, as shown. When the parts are thus put together they are secured firmly by bolts and nuts K, which bolts, as will be observed, p ass through the plates, lling, and flange B, with a nut upon the outside, or otherwise secured in place, there being a series of holes through the said parts for the reception of screw-bolts to secure the parts together. These bolts, it will be noted, are smaller than the bolt-holes through the flange B, for a purpose hereinafter stated.

By this construction and arrangement of the parts comprising the wheel, the principal weight is brought upon the filling, as the periphery of which is in tightly-fitting contact with the interior face of the rim or tire A at J, and the base of the filling also fits tightly upon the sleeve H of the hub, and as there is an annular space, I, between the sleeve H and on each Side of The inthe web B, and space at a a between the pethere will be a springing or elastic character to the wheel, which will cause the cars to run with less wear and strain, and with more ease to the passenger than with wheels of the usual construction. There is elasticity enough in this wheel, described, to resist the heavy jars, blows, and strains which are experienced more or less by a solid iron wheel. The interior web or flange B insures great additional strength to a cast-iron tire, (and which may be used in steel tires cast.) In case the rim should break or crack through when in use, the web with its fastenings would so hold the wheel as to prevent accident therefrom. In the event of the rim and flange breaking or splitting together from the circumference of the rim to the base of the web, these broken parts could not be separated or detached from the Wheel, owing to the method of so securely fastening the parts together, and to the flange or web B. The section couldnot be detached in case of such fracture without removing the bolts.

Claim.

set forth.
