VEHICLE-HUB.

SPECIFICATION formingpart of Letters Patent No. 650,932, dated June 5, 1900.

Application filed October 6, 1899.

To all whom it may concern:

Be it known that I, CARL D. FISCHER, a citizen of the United States, residing at 'Wapakoneta, in the county of Auglaize and State of Ohio, have invented certain new and useful Improvements in Vehicle-Hubs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of metal hubs having mortises designed to receive wooden spokes having their inner ends provided with tenons fitting in the mortises and for use especially in automobiles, but adapted also to other vehicles requiring strong and symmetrical hubs.

The special object of my invention is to providea compact and strong solid metal hub, as an article of manufacture, having circumferential flanges of great strength for guarding and supporting the inner ends of the spokes, the latter being provided with tenons to fit into mortises between the flanges.

The invention consists in the construction hereinafter described, and defined in the claims.

The accompanying drawings represent, in Figure 1, a side of the hub; in Fig. 2, a crosssectional view, taken on line 2 2, ig. 1, through the hub at one side of the inner ends of the spokes,the latter-being partly sectional; in Fig. 3, a longitudinal section of the hub on line 3 3, Fig. 1, showing the shape of the interior or axle-box.

The hub A is made with a series of separate mortises B around its central exterior, just far enough apart to allow the inner ends of the spokes to be assembled and be in close contact with each other when their tenons are resting in the mortises B, there being a substantially-solid mass of metal 0 yet beneath the inner ends of the mortises.

The circumferential flanges D extend outward from the hub at the ends of the mortises for forming side supports to the inner ends of the spokes and are provided with holes, as 'is usual, for the passage of bolts when the spokes have had their tenons inserted in the sockets or mortises. The ends Serial No. 732,751. (No model.)

and F or rim ends of the hub extend from the outer portions of the interior strengthening mass of metal 0, as shown in Fig. 3, presenting a longitudinal section of axle-box. It will thus be seen that the hubs interior at each of its ends is enlarged and that notwithstanding the rim ends of the hub are of sufficient substance for required strength the symmetrical proportions of the hub in its ontirety having regard, withal, for solidity and strength where thelatteris specially required, are features of construction of a notably meritorious character in an integral metallic hub.

The circumferential flanges D having their bases involved or arising from and strengthened by the mass of metal 0 and continuing from that immediately beneath the mortises afiords strong and durable side supports for the inner ends of the spokes, and the general interior shape of the hub adapts it for ready application to axles, while the exterior configuration presents features of utility, strength, and symmetrical proportions.

The hub may be made of any kind of metal, but is preferably a malleable-iron casting.

Hubs have been formed entirely of metal and embodying constructions adapted for receiving the inner ends of spokes, tenons and mortises being sometimes provided, and metal flanges for side support of the spokes being sometimes formed on parts of certain metallic attaching parts, and in some cases hubs have been cast of metal in a single piece, with circumferential flanges adjacent to a series of sockets or mortises, the latter having their inner ends connecting with each other in an annular space. Rods or bolts are commonly used to pass through said metal flanges and through openings formed by halfround notches in the adjacent sides of the inner ends of the spokes.

No hub, so far as I am aware, has been made of solid metal throughout having mortises or sockets of complete inner closure for receivingspoke-tenons and having circumferential flanges immediately adjacent to and eX- tending out beyond the mortises and having an interior of a substantial strengthening mass of metal beneath the mortises, being a solid or integral hub with a hollow interior forming the axle-box.

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

1. A solid metallic hub composed of integral parts, having an axle-box, a circle of mortises with closed inner ends to receive teuons or spokes, circumferential flanges adjacent to and extending out beyond said lnortises and provided with suitable holes for bolts, substantially as and for the purpose described.

2. As an article of manufacture, a solid cast metallic hub, having an axle-box of di minished interior at the center to afford a strengthening mass of metal 0, a series of mortises B, in the exterior and opposite thereto, and circumferential flanges D, adjacent "ifi'presence of two witnesses.
