WILLIAM NEHRING, OF'CINCINNATI, OHIO, ASSIGNOR TO TIEIE QUEEN CITY MALLEABLE IRON COMPANY, OF SAME PLACE.

VEHICLE-WHEEL.

SPECIFICATION forming `part of Letters Patent No. 257,744, dated May 9, 188C. Application filed February 20, 1882. (No model.)

To all whom it may concern:

Bc it known that I, WILLIAM NEHRING, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Manufacture of Iron 4Wheels., of which the following is a specification.

My invention relates to an improved manufacture of malleableiron wheels,designed particularly for Wheelbarrows and trucks for use Io in foundries, furnaces, factories, and like establishments, in blast-furnace buggies, &c.

III the accompanying drawings, Figure l is a perspective View of a wheel embodying my invention. Fig. 2 is an axial section of the same. Fig. 3 is an inner prole of one section of the hub and a portion of the attached skeleton. Fig. 4 is an internal profile of the other hub. Fig. 5 is an axial section of that form of my hub which has a metal core. Fig. 6 is a zo transverse section of the same on the linerrzc, Fig. 5. Fig. 7 is a perspective rear view of one of the core-sections.

The rim A and spokes B are all cast in .one integral piece called the skeleton or spider.

The hub consists of two similar hollow truncated cones, C C', having flanges D, of which one or both are formed with notches d to rcceive the inner ends of the spokes. The said 3o spokes and anges are perforated,as at b and d', for the reception of rivets E, uniting together these three castings, which constitute the wheel.

Axial orifices F receive either a shaft driven tightly into the hub, so as to revolve with the same, or a non-rotary axle upon which the wheel revolves. In the latter case the walls f 0f said orice, which come in contact with theaxle, are preferably caston a chill for greater 4o durability and service.

The spider A B and hub-cones C C are preferably cast of strict white 7 iron and annealed sufficiently to render them Inalleable, and yet `so as to preserve intact the chill or hardened will subject it to severe treatment the interior 5o of the, hub may be re-enforced by a core or filling, G, of cast-iron. Alongitudinalgroove, g, in the said cores periphery may receive a tongue, c, on the interior ofone ofthe cones, C.

y I claim as a new article of manufacture- 1. The Wheel of malleable castiron, composed of spider A B,having theinner extremities of its spokes without direct cast connection, and secured by rivets E between the anged hollenT concs or frustums C C', sub- 6o stantially as set forth.

2. In described combination with the spider A B, cones C C', aud rivets E, the core G, Whose groove g receives a tongue, c', that projects from the interior of one of the cones, for the purpose designated.

3. The wheel of malleable cast-iron, composed of spider A B, having theinnerextreniities of its spokes without direct cast connection, and occupying notches d in flanges D of 7o the bottom frustums, C C', to which they are secured by bolts or rivets E, substantially as set forth.

In testimony of which invention I hereunto Set my hand.

WILLIAM NEHRING.
