HUB.

SPECIFICATION forming part of Letters Patent N 0. 691,735, dated January 21, 1902.

Application tiled April 29, 1901. Serial No.57,947. (No model.)

To @di 'Lu/tom t may concern: d

Be it known that LJOHN CALVIN WORKING,

of the city of Denver, county of Arapahoe,

view, partly in section, showing my improved hub and the mannerof attachment of the spokes thereto. Fig. 3 is a detail, partly in section, of the hub,'showing the manner of attachment of the spokes thereto. Fig. 4 is an end view of the hub, showing the ends of the bolts illustrated in Fig. 2. Fig. 5.is a view similar to Fig. 1, but showing the manner of attachment of the spokes of the wheel when the hub is made of metal. Fig. 6 is an end view of the main hub portion, showing the slots therein and spokes fitted into some of said slots. Fig. 7 is a longitudinal sectional view of my said hub when constructed of metal, showing the same in detail and also the manner of attaching the spokes thereto and the assemblage of the whole, together with one form of axle illustrated running therethrough. Fig. 8 is an end View of the entire hub.

My invention relates to hubs used in wheels having bowed spokes of resilient material. As shown at 1, said spokes are preferably pivotally attached to stirrups placed upon the inner side of the rim of the wheel, preferably by means of a bolt running through sides of the stirrup, around which the end of the spoke is curled, forming an eye.

I will first describe the construct-ion of my improved hub when made of wood and afterward will describe the same when composed all of metal. The former is shown more particularly in Figs. 1 to 4 and the latter in Figs. 5 to 8.

In Fig. 2, 4indicates the round wooden hub, 5 the spokes fastened thereto on one end thereof, and 6 the spokes entering thereinto and attached thereto at the other end of the hub. 7 indicates a bolt running entirely through the hub, binding thereto the flanges 8, which by means thereof are bound firmly to each end of the hub. Said anges 8 have collars 9 projecting laterally from the central portion of the same, forming a-space through which the axle 10 of the vehicle passes. This axle may be of any desired pattern. As shown at 11, this collar projects on the end side of the hub beyond the end of the axle and the axle-cap, protecting it from harm. Bolts 7 are made operative by their heads 12 and the nut 13. After the flanges 8 have been fitted over the wooden hub the bolts 7 are run through the flange on one end of the hub, through the wood, and through the opposite flange and the nuts 13 screwed home, whereby the whole is bou nd together as a firm and compact structure. The lianges 8 have on their inner side a rim 14, which encircles the end of the wooden part of the hub completely, except that at the point where each spoke enters the hub said rim is notched to allow said spokes to pass therethrough. As shown, the several spokes are suitably attached to the rim ot' the wheel and alternately connected with opposite sides of the hub-that is to say, (referring to Fig. 1,) While the spoke numbered 15 will be brought to one end-of the hub, as indicated at 5, Fig. 2, the spoke numbered 16 will enter the hub at the end opposite to that where the spoke numbered 15 is attached, (designated at 6, Fig. 2.) Spoke numbered 17 will againbe attached to the same end of the hub as that numbered 15, and spoke'numbered 18, again alternating, will be attached at the same endof the hub as the spoke numbered 16, and so on around the wheel.

The spokes are attached to the hub in the following manner: Each spoke is provided with an eye 19, which is formed by the end thereof simply being turned around into that shape. Passing through the lianges 8 at the part marked 20 are the bolts 2l, which also pass through the eyes 19. The nuts 22 holdF95 said boltsv in place, and the combination of the two assists in binding the structure together. Slots 23 are out in the wooden portion of the hub 4 at the required number of points on its circumference, allowing the IOO spokes to enter from the rim of the wheel to be attached in place in the hub. These spokes are attached to the hub in the following manner: The flanges 8 not being attached to the wooden part of the hub, the slots 23 are exposed to view from both ends of the hub, as well as places for the eyes 19. The spokes are simply slipped into the slots and eye-spaces at their respective ends of the hub. The flanges 8 are then placed in position, the bolts 21 are driven in through both flanges 8 into the wooden portion 4, and the nuts 22 screwed home.

24 indicates the rubber or other tire to the Wheel, attached in any ordinary or desired manner.

When the hub is constructed entirely of metal, some variations in these parts are necessary. Vthile any form of axle may he used in this hub, in the drawings I have shown it with a Timken roller-bearing.

As part of my special hub construction I provide a cap 25, which incloses the end of the hub and axle away from the body of the Vehicle. The screw threads 26 form the means of attachment of this cap to the main part of the hub. This main portion of the hub 27 is constructed entirely of metal and has projecting therefrom two annular flanges 28 and 29, which project from the periphery of the hub at points adjacent to its ends. Said annular flanges are both provided with slots, as in the wooden hub before described, having at the bases of said slots, near the center of the hub, holes drilled thereinto approximately the size of the eyes upon the spokes, which are inserted into said metal hub in the same way as into the wooden one-that is to say, from the ends-by being slipped into the slots in their straight portion, the eyes being inserted into the round holes at the bases of the slots. The construction of these slots is shown at 30, and the holes for the eyes at 31.

32 indicates the appearance of the end of the hub when the spokes are in position, but before the flanges 8 are adjusted to their places at the ends of the hub. To hold the spokes within the slots, I provide annular flanges or caps 33, which fit to the ends of the hubs at both ends, there being two to each hub. These flanges bear upon the central portion of the hub 27 at 34E and are retained in position at the bottom, where they rest upon said central portion of the hub, by the cap 25, before described, and the cap 35 at the other end of the hub. The cap 35 is screw-threaded and fastens upon the main portion of the hub in a manner similar to the cap 25, but differs from it in having an aperture in its center for the passage of the axle. The upper part of these flanges or caps 33 is held firmly in position bearing against the flanges 29 by means of the bolts 36, which run through the flanges 29 and flanges or caps 33 and have heads 37 and nuts 38 to retain them in place. The flanges 33 have the rim 14, the same as in the Wooden form of this hub, which is notched at various parts of its circumference for the ad mission of the spokes.

I am aware that many minor changes in the form and arrangement of the parts constituting the different parts of my invention maybe made and that minor changes of construction in the same may be made without departing from the nature and spirit thereof.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

1. A hub adapted to receive spokes at points .adjacent to its ends, having on its periphery raised portions formed integral therewith containing grooves for the reception of the spokes, caps to hold the spokes in said grooves, and caps 25 for retaining said caps in place, substantially as described.

2. The combination of main hub portion having flanges, grooves in said flanges, spokes tting therein, caps to retain said spokes in said grooves, and screw-threaded caps to hold said first-mentioned caps in position, substantially as described.

3. A hub comprising a central core, having grooves in the ends thereof extending from the periphery a suitable distance toward the center thereof, with holes at the inner ends of the same, adapted to receive and contain flat resilient spokes, having eyes formed on their inner ends adapted to fit in said holes.

4. A hub comprising a central core having raised portions on its periphery adjacent to its ends, grooves in said raised portions adapted to receive and contain flat resilient spokes, said grooves terminating in holes adapted to receive and contain eyes formed on the ends of said spokes.

5. A hub comprising a central core, grooves in said hub adjacent to its ends adapted to receive and contain flat spokes, and a flange TOO or cap having a notched or recessed rim lat,

adapted to overlap a part of said central core, and in said recesses to afford bearing-surface for said spokes.

6. A hub comprising a central core having grooves therein adapted to receive and contain resilient spokes having eyes on the inner ends thereof fitting into holes at the inner ends of said grooves and bolts passing through said eyes and into the main hub portion.

In testimony whereof I have hereunto affixed my signature, in the presence of two Witnesses, this 22d day of April, 1901.

JOHN G. WORKING.
