'SPECIFICATION forming part of Letters Izatent No.` 237,398, dated February 8, 1881.

l Application filed July 24, 187i).

0 all whom it may concern Be it known that I, PETER `JEL LINDsEY, `of

Lockport, in the county of N iagara and State i that class of car-wheels which are used on elevated and street railways; and it has for its object the construction of a light, strong, and non-resonant wheel.

The invention consists, principally, of a car- Wheel composed of a recessed metallic disk, a wooden tread having the inner portion of the flange formed with it, and an outer clampingplate, as will' be hereinafter more fully set forth.

Inthe accompanying drawings, Figure 1 is a front elevation of my improved car-wheel. Fig. 2 is a sectional elevation thereof. Fig. 3 is a front elevation with the outer clampingplate removed. Fig. et is a front elevation of the metallic disk. Fig. 5 is a rear elevation of two sections of the wooden tread. Fig. Gis a sectional view of the tread of the wheel, on an enlarged scale. Y

Like letters of reference designate like parts in the several figures.

A represents the metallic disk forming the body of the wheel. It is provided at its center with a projecting hub, b, by which the wheel is secured to the axle in the usual manner, and at its circumference with a flange, c, which projects beyond the face of the disk A, so that the latter is depressed or recessed between the iiange c and hub b. 1

d are stiffening ribs or webs connecting the hub b with the flange c on the face side of the disk A. A i

D represents radial sections, made of some suitable hard wood, and arranged upon the face side of the disk A, between the hub b and ilange c of the disk.

E is an annular clamping-plate, which surrounds the hub b, and is placed against the outer side of the sections D. The sections D are preferably made tapering from the hub toward the tread, and the disk A and clampingplate E are made dished or concave on the sides contiguous to the sections D7 so as to form a dovetail groove, whichisurrounds the hub, and in which the sections D are firmly held, Iasclearly shown in the drawings.

f are fastening-bolts, passing through 'the disk A, sections LD, and outer clamping-plate, -E,for securing these parts together. Thebolts fare preferably located at the joints of the sections D, as `shown in Fig. 3, whereby the bolts are made to serve at the same time as dowel-pins, and prevent the displacement of the sections in a radial line. The fasteningbolts f are placed at every alternate joint of the sections D, so as not to interfere with the ribs d of the disk A. The circumference or outer circular surface of the sections D is so shaped as to form not only the tread of the wheel, but also the inner portion, g, of the iiange, which runs in contact with the rail.'

By constructing the sections in this manner theouter joint between these sections and the flange c is located at a point where it is not liable to come in contact with the rail, and the chipping or breaking ont of the flangein passing over a frogis thereby avoided. By this construction of the sectionsD an unbroken surface of wood only is brought in contact with the rail, both on the top and side thereof, and the noise produced by the wheel in rollin g over the rail is thereby greatly lessened. The two sections D, which are tted against each rib d, are recessed on their contiguous sides, as shown at h, Fig. 5, to receive and coverthe rib d. it" is a packing composed of sheet-lead,

rubber, felt, or some other suitable non-con-V ductor of sound, and arranged, respectively, between the sections D and the diskA, and the outer clamping-plate, E, to prevent the transmission of the sound through the body of the wheel. v

The disk A is preferably cast of malleable iron or cast-steel, and its iiange b is chilled. The sections D are preferably made of hickory or some similar hard wood.

In order to render the sections D impervi` ous to water and perfectly smooth they are preferably saturated with oil which holds iiour of emery in suspension.

My improved wheel is very light and strong, and having its tread and the inner portion of its ange formed of non-resonant material, it is' especially adapted for use on elevated and IOO street railways, Where the noise caused by ordinarymetalliccar-wheelsis veryobjectionable.

My improved Wheel is constructed at comparatively small cost, and its sections forming the tread can be readily replaced when Worn out.

I am aware that Wheels have been made embodyin g in their construction the broad idea of combinin g Wood and metal to obtain strength and avoid resonance 5 and I am also aware that in this class of Wheels it has been suggested to form the tread of the wheel of wood, .and that compound wheels have been provided with noiseless tires, and I do not wish to be understood as making claim to any such broad features ot' construction 5 but I claim as my inventionl. A car-Wheel composed of the disk A,hav`

ing a iiange, c, formed thereon, and projecting laterally beyond the face of the disk, sections D, forming the tread of the wheel, and the inner portion, g, ofthe han ge, and an outer clamping-plate, E, substantially as set forth.

2. A car-wheel composed of the dished disk A, provided with thelaterally-proj ecting flange o, sections D, made tapering from the hub toward the tread of the Wheel, and the outer dished clamping-plate, E, substantially as set forth.

3. The combination, With the disk A, provided With the laterally-projecting tlange c, projecting beyond its face, hub b, and connecting-ribs d, of the sections D, formed With the annular projecting lip g, and fasteningbolts f, arranged at the joints of the sections, substantially as set forth.

4. The combination, with the disk A, nonresonant sections D, and outer clamping-plate, E, of the packing sheets or plates iz", arranged between the sections D and the disk A, and outer clamping-plate, E, substantially as and for the purpose set forth.
