VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 478,918, dated July 12, 1892.

Application filed August 22, 1891- Serial No. 403,385. (No model.)

To all whom it may concern.-

Be it known that I, CLINTON D. CANNON, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented a new and useful zVheel, of which the following is a specificaion.

Myinvention relates to vehicle-wheels; and it has for its obj ect to provide a metallic vehicle-wheel in which the hub is cast on the spokes thereof, and to provide a construction whereby the strain of the spokes will not come directly upon the metal cast therearound, and thus avoid the tendency to loosening and bending out of shape, and at the same time holding the spread of the two rows of spokes which are used in my improved wheel, and by constructing the hub proper or at least usinga softer metal than the spokes and the devices holding the spokes are constructed of when the same is cast the softer metal thereof does not burn the life and strength out of the spokes, as would be the case if the harder metals-like molten iron were used; and with these and other objects 1n view the invention consists in casting a soft-metal hub upon double rows of spokes, which are retained and held in position by the construction and arrangements hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims;

In the accompanying drawings, Figure l is a perspective view of a metallic vehicle-wheel skeleton preparatory to the molding of the soft-metal hub thereon. Fig. 2 is a similar View of the same with the hub-mold thereon and one side of the same being removed to show the interiorly-inclosed spokes and spokering. Fig. 3 is a perspective view of the completed wheel. Fig. 4. is a vertical transverse section through the hub-flange carrying the set-screw. Fig. 5 is a detail in perspective of one of the spoke-holding rings. Fig. 6 is a similar View of one of the double-wire spokes.

Referring to the accompanying drawings, 1 designates the circular rim of the wheel having a fiat tread and adapted to receive the outer portions of the wire spoke 2. The said spokes are preferably constructed of wire and are bent upon themselves and project through the pairs of perforations 3, located in the periphery of said rim and at certain intervals, according to the number of spokes desired to be used in making the wheel, thus forming an elongated U-shaped double spoke, the closed end of which bears upon the solid portion of the rim between the perforations through which the said spokes project, and the free ends thereof terminate in the right-angularlybent portions 4, which are adapted to engage and be held to the strengthening and anchoring ring 5. The rings 5 are constructed of a hardened metal and constructed of a suitable size, according to the size of the hub, and are provided with a series of perforations 6, that are adapted to receive the bent ends of the said spokes, which after their insertion in the said perforations are then bent up to form a hooked end engaging said rings and are thus prevented from displacement. The said rings are suitably spaced apart by means of the spacing-blocks 7, that are forced between the double spokes, in order to spread the rings the desired distance apart and hold the same in their spaced position While the softer-metal hub is being cast thereon,and thus straining every spoke against the center ring that is designed to be inclosed within the metal jacket forming the hub, and thus bringing the rim of the Wheel to a proper circle, while it brings the straining-pressure of the spokes against the iron ring at the hub end of the spokes, where, as said, a softer-metal hub is put on for the purpose of holding the spread of the two rows of spokes which is made by the wedges or spacking-blocks 7. One of said rings is further provided with a projecting lug 8, provided with a screw-threaded perforation 9, extending through the entire length thereof and the width of said ring, the upper edge of said lug being designed to be flush with the rim of the hub, while the interior periphery of said ring is designed to register with the internal bore of the cast hub; Aftcr the skeleton of the wheel is formed in the manner as just described, the various parts are incased in the double-flange mold 10, which is constructed of the usual material and is provided with the

flanges

11 and 11, respectively, which incase the spaced rings and are provided with perforations through which the spokes therein project, and to complete the said mold a circular core 12, snugly fitting the interior bore of said ring, is placed therein and is designed to leave a circular opening through the cast hub, which will be of a size sufiieient to receive the axle-box in the manner to be described. The skeleton wheel is now incased by the ordinary molding process by the soft-metal jacket 13, which is molded around the spokes and the strengthening and anchoring rings in a form corresponding to the shape of the forming-mold ineasing the same, and thus, as can be readily seen, while accurately spacing the double spokes and the separate rings apart the same is relieved from any pressure or strain which might be exerted upon the spokes, which will at all times fall directly upon the ineased rings.

A metallic axle-box 14: is designed to extend transversely through the center of the hub and fit sn ugly within the perforation left by the core of the mold and is designed to be held firmly therein by means of the set screw 15, passing through one of the flanges of the hub and through the threaded perforation of the lug flush therewith and engaging the recess or notch 10 therein, and is thus held securely in place therein, while the axle of the vehicle is left to freely work within said boxing, which in case of becoming stuck to the axle may be easily separated from the wheel and the hub by releasing the set-screw holding the same within the hub.

The advantages and the construction of the herein-described wheel is now thought to be apparent without further description.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is--- 1. In a metallic vehicle-wheel, the eombination, with the metal rim, of the opposite spaced anchoringring, the double spokes having their opposite ends secured to said rim and anchoring-ring, the soft-metal hub-jacket in closing said ring and the hub ends of said spokes, and a supplemental axle-box detachably secured within said hub-j acket, substantially as set forth.

2. In a metallic vehicle-wheel, the combination, with the rim, of the anchoring-rings provided with a series of perforations, the U- shaped double spokes passing through said rim and engaging the perforations in said rings, and of the soft-metal integral hub inclosing said rings and the hub ends of said spokes, substantially as set forth.

3. In a metallic vehicle-wheel,the combination, with the rim, of the spaced anchoringrings provided with a series of perforations, the U-shaped double spokes passing through said rim and provided with hooked ends adapted to engage the perforations in said spaced anchoring-rings, and of the soft-metal integral hub inclosing said rings and the hub ends of said spokes, substantially as set forth.

l. In a metallic vehicle-wheel, the combination, with the rim, of a central anchoring-ring provided with an outwardly-projecting lug having a screw-threaded perforation, spokes secured to said rim and said anchoring-ring, a soft-metal hub inelosing said ring and the hub ends of said spokes, an axle-box located within said hub, and a set-screw adapted to pass through the hub and said perforated lug and ring and secure said box within the hub, substantially as set forth.

5. In a metallic vehicle-wheel, the combination, with the rim, of spaced anchoring-rings provided with aseries of perforations, a screwthreaded lug projecting outwardly from one of said anchoring-rings, the U-shaped double spoke passing through perforations in said rim and terminating in hooked ends, adapted to engage the perforations in said spaced anchorin grin gs, a softanetal integral hub inclosing said rings and the hub end of said spokes, an axle-box registering with the interior bore of said hub, and a set-screw adapted to pass through the hub and said perforated lug and ring and secure said box within the hub, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

CLINTON D. CANNON.
