IMPROVED GAR-WHEEL.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES E. KLEINSGHMIDT, of Cleveland, county of Cuyahoga, in the State of Ohio, have invented a new and improved Mode of Constructing Railroad-Car Wheels; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

Figure l is a perspective view. v I

Figure 2 is a side view, with a portion of plate broken out.

Figure 3 is a vertical section. Y W I The nature of this improvement relates to the construction of railroad-car wheels in separate parts, said parts being so constructed and arranged as .to constitute a compact, durable wheel, of lighter weight and possessing greater strength than the ordinary cast-iron wheel, and one also that may be easily and readily repaired without incurring the loss of the entire wheel.

The construction and arrangement of my improved wheel is as follows: A represents a car-axle, which may be wrought in the usual manner, and may have a huh, 11, formed upon it, and comprisinga part of it, or the hub may be made separate and shrunk upon it, or it may be-keyed upon the axle inthe usual way for securing the same. The periphery of said huh, I make bevelled from the middle to the ends, the purpose of which will be hereafter seen. B B are wrought-iron'or steel plates, cut round, and are bent or curved, as seen in fig. 3, and

have a hole in the centre, which fits the huh I), and has a flange, a, bent or turned inward at an angle to correspond with the bevel of the hub. Said flange, instead of being bent on said plates, may have an angle-iron ring bolted on to them, and fitting the hiib. The outer edge of said plates B has also a flange, c bent upon them at an angle similar to the inside one. D represents a tire, which maybe rolled, of steel, or it may be of wrought or chilled cast iron, and also has its inside surface (I bevelled in like manner to the hub. E E are rings, which are made thinner gradually from their outside to their inside edge, to correspond with the slant or curve of the plates B B, and'are intended to serve aswashers for the bolts and nuts. The-rings and plates are provided with holes, through whieh'the bolts ff pass, and to prevent the bolts from becoming loosened, byjarring 'or otherwise, the ring E has a screw-thread cut in its holes, and the bolts are: screwed .through them, and the nuts 1: are screwed down tight upon them, thus acting as jam-nuts.

It will be seen, by reference to figs. 2 and 3, that the flanges c and 0" of the curved plates B B bear against the bevelled surfaces of the hub b and of the tire D, and that, by the drawing of the bolts ff, the whole structure is held firmly together. The plates B B can be cut and formed of wrought iron orsteel, which enables my wheelto be made much lighter in weight than the ordinary cast-iron wheels, at the same time possessing equal orjgreater strength, and not liable to be broken. The tire being made separate, and which may be ofwrought iron, or steel, or chilled cast iron, enables them to be made more durable, and tube readily replaced, whenever they become worn, by others, without the necessity of throwing aside the entire wheel. The other parts seldom beome worn out or broken.

The practical advantages (if this method ot'.constructing ear-wheels are the simplicity and cheapnessof manufacture, great durability, and less liability to get out of order, and the readiness with which the tiresmay be replaced, and also their being of less weight than those now in use.

Having thus described my invention, what I claim, and desire to secure by Letters Patent is The plates B 13, having flanges c e ontheir outer and inner edges, the hub 15, having a bevelled periphery,

the tire D, havingits inner surface also bevelled, and the rings E E and the bolts ff, all constructed, arranged,

and combined in the manner described and for the purpose set forth.
