METAL vill-IEEEV SPECIFICATION forming part of Letters Patent N o. 730,591, dated June 9, 1903.

Application led July 11, 1900.

To @ZZ whom, t may concern.-

Beit known that I, SAMUEL L. ALLEN, a citizen of the United States, and a resident of Moorestown, State ofV New Jersey, have'in- Vented certain new and useful Improvements in Metal Wheels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. y

This invention relates to certain improvements in the construction of metal wheels,

and hasfor its principal object to simplify and cheapen the construction and at the same time produce a wheel having great strength and durability. y

In order that my invention may be fully understood by those skilled in the art to which it appertains, I will proceed to describe it, reference being had to the accompanying drawings, in which- Figure l is a side elevation of a wheel embodying my invention, l the central hub or bushing being shown in section. Y Fig. 2 is an enlarged sectional view taken substantially on a radial line through the center of the hub and through a continuous portion of the rimV at the end of a spoke.' Fig. 3 is an elevation,.on an enlarged scale, of the hub, one ofY the hub-plates being removed for the purpose of illustrating the inner portions ofthe spokes. Fig. 4 is a sectional view taken about on the line 5 5 of Fig. 3. Fig. 5 is a detail view of one of the hub-plates, illustrating the grooves formed on their inner faces; and Fig. 6 is a detail sectional view taken about on the line 7 7 of Fig. 5. l

The rim A of the wheel consists of a strip of fiat sheet steel or iron bent to circular form in any well-known manner..

In the center ofthe rim A are punched a series of apertures ce, equidistant apart, correspondingin number to the number of spokes desired in the wheel, the said apertures loeing punched in such ainanne'r as to forni the iianges a' on the under side of the rim around each aperture. i

The spokes comprise the steel rods B, of a diameter corresponding to the diameter of the apertures o. at their outer ends, while theirintermediate portions are preferably tlattened out in the shape illustrated in the drawings. Each pair of spokes is made of a single rod bent at its central portion in the inan- -ner illustrated most clearly in Fig. 3 of the drawings.

Near the outer ends of each of vthe spokesV B is formed a shoulderc, .which is integral with the spoke,as shown in Fig. 2 of the drawings. These shoulders should be so located with respect to the ends of the spokes as to bear against the iianges a' when said spoke ends are inserted in the apertures a of the rim. After the ends of the spokes are inserted in the rim, as above described, they are upset or riveted and made Hush with the outer surface of the rim, the curved or rounded edge of the aperture affording a space into which the end of the spoke spreads as it is upset or riveted.

The huh comprises two plates D D', which .may be forged orstarnped out of sheet metal.

The plates D D are each provided with radial wedge-shaped grooves d, corresponding in shape to the contour of the spoke, and are adapted to embrace a portion of the said spokes when the said two plates are clamped together.

t the'inner ends oi' each of the grooves d I provide a substantially circular groove d', concentric with the axis'of the wheel and merging into andforining a continuation of `the grooves d. These grooves Zand d! have inclined or wedge-shaped walls, which bind against the sides of the spokes B.

-The centers of the plates D D. are provided with the apertures f, struck out in such a manner as to forni the flanges f', which when the two plates are clamped forni a central bore for the bushing G. This bushing G is provided with a ange g nearone end, which bears against the end of .the iiange j", while its other end is screw-threaded for the reception of a nut-g2. A central bore or aperture is provided through the bushing G for the passage of the wheel-axle.

In Fig. 2 of the drawings I have shown the lower plate D as having a bevel-gear d2 formed integral therewith, also having the central sleeve or bushing formed integral with said section D. When this form is used, I forni on the inner face of the plate D' between the radial grooves d the studs e, having their ends reduced and screw-threaded, as shown in Fig. 2 of the drawings. The oppositely-disposed plate D is provided with apertures Which register with the studs e when both plates are placed in position, the screw-threaded shanks extending through said apertures and adapted to receive the nuts e2, by means of which the two plates are securely held together.

Vhen it is not desired to use bevel-gear cl2, both of the plates D and D are made alike and are clamped together by the stud-bolt e. (Shown in detail in Fig. 6 of the drawings.) Thus when the spokes are riveted in the rim, as heretofore described, and the plates D D' are placed in position around the inner portions of the'spokes and clamped together by means of the bolts e and nuts e2 and the bushing G the inclined shoulders or side walls of the grooves d and d Will come in contact with and bind against the sides of the spokes B with a wedge effect, the grooves d serving to draw the spokes toward the center of the wheel and against the bushing G and securely hold them in position.

The platesD and D are preferably made of sheet-steel struck up in the desired shape, having the flanges f drawn thereon in the process oi' stamping.

The rim A is formed of a single strip of metal, as heretofore described, and after bending into a circular form the meeting edges overlap, as illustrated in Fig. l of the drawings.

The shape of the inner portions of the spokes may be varied or modified in form so long as the wedge feature is retained, and other changes might be made in the details of my Wheel without departing from the spirit and scope of my invention.

Having thus described my invention, what l claim, and desire to secure by Letters Patent, isd l. In a metal wheel, the combination with the rim of spokes secured therein, each pair of spokes being composed of a single rod bent to form an angle at its center, and having inclined or tapering edges formed thereon, a pair of hub-plates adapted to embrace the angularly-disposed and inner portions of the spokes, and having inclined or wedge-shaped indentations formed therein in which the spokes rest, and means for clamping said plates together, substantially as described.

2. In a metal wheel, the combination with the rim, of spokes formed in pairs each pair comprising a single rod secured at each end to the rim and having its central portion bent to form an angular intermediate section, the innerl straight portions and angular1y-dis posed portions of each spoke being attened out to form wedge-shaped edges on each side, a pair of hub-plates having wedge-shaped grooves or indentations adapted to receive the inner portions of the spokes, and clamping-bolts for securing the two plates together, substantially as described.

3. In a metal wheel, the combination with the rim, of spokesv formed in pairs each pair comprising a single rod secured at each end to the rim and havingits centralportion bent to form an angular intermediate section, the inner straight portions and angularly-disposed portion of each spoke being iiattened out to form wedge-shaped edges on each side,

va pair of hub-plates having wedge-shaped grooves or indentations adapted to receive the inner portions of the spokes and having central openings formed therein, a sleeve or bushing'adapted to said opening and means for securing the same in position, substantially as described.

4f. The combination with the rim, of spokes formed in pairs each pair comprising a single rod secured at each end in the rim, having its central portion bent to form a curve substant-ially concentric to the center of the wheel, and having inclined or wedge-shaped edges formed thereon, a pair of hub-plates having radial grooves provided with inclined or wedge-shaped side Walls and having central apertures formed in said hub-plates and concentric grooves orindentations formed around said apertures having their outer walls inclined and adapted to bear against the curved portion of each pair of spokes, a bushing passing through the hub-apertures, and means for securing the parts together, substantially as described.

In Witness whereof I have hereunto set my hand this 9th day of July, A. D. 1900.

SAMUEL L. ALLEN.
