WHEEL FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 574,538, dated January 5, 1897. Application filed September 17, 1890. Renewed December 3,1892. Serial No. 454,005. (No model.)

To all whom, t 77mg/ concern.:

Beit known that I, HIRAM F. HAMMON, a citizen of the United States, residing at Palm Beach, in the county of Dade and State of Florida, have invented certain new and useful Improveme nts in Wheels; 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 generally to wheels, such as may be employed for vehicles, windmills, water-wheels, pulleys, and other structures requiring light and strong wheels, and particularly to suspension-wheels in which the load or weight is supported by the upper spokes for increasing their strength and that of the wheels, instead of the weight being held by the lower spokes, as in most other wheels, which renders them less strong and also liable to flexure; and my invention consists in the improved construction and arrangement or combination of parts hereinafter fully disclosed in the description, drawings, and claims.

The objects of my invention are, first, to provide a wheel with an improved arrangement of metallic rods or spokes for counteracting the dishin g and torsional strains thereon, and, second, to provide the same -with a peculiar and useful construction and arrangement of hubs or collars and rim to which to secure the inner and outer ends of said spokes. These objects are attained by the construction of wheel illustrated in the accompanying drawings, forming part of this specification, in which the same referencemumerals indicate the same parts, and in which- Figure l represents a side view of my improved wheel; Fig. 2, an axial section of the same 5 Fig. 3, an axial section of a modified construction of wheel having a central hub or collar arranged between the two outer ones; and Fig. 4, an enlarged vertical sectional view of one of the hubs or collars, showing the annular groove near the periphery thereof, the slots or holes in the upper wall of said groove, and the inner ends of a number of the spokes secured therein. Figs. 5 and 6 are respectively side and axial sectional views of a modified construction of wheel in which only nonradial or tangential spokes are used.

In the accompanying drawings, the numeral l indicates the hubs or collars, which are preferably formed with annular grooves 2 in their outer faces near their peripheries. These .collars may be either shrunk or otherwise tightly secured to the axle or to a hub or sleeve which turns therewith, or, if desired, they may be loosely fitted upon said axle, according to the character of the machine in which the wheel is employed.

The rim 3 may be either plain or hanged and may have a tire, cit-her plain or hanged, secured thereto.

Pai rs or sets of radial metallic rods or spokes el are so secured with their outer ends in the rim and with their inner ends in the peripheries of the hubs or collars l as to incline inwardly and cross each other near their outer ends, said outer ends being secured near the edges of the rim, as plainly shown in Figs. 2 and 3. .These spokes are screwed into the rim at their outer ends and provided at their inner ends with nuts 5, which are inserted through slots or holes 6, formed in the peripheries of the hubs or collars and which open into the grooves 2, within which said nuts lit and are secured.

Other pairs or sets of spokes 7 project tangeutiall y from and are fastened to each of the hubs or collars l and also to the rim 3, near the edges of the latter; also, they are secured at their inner and outer ends to said hubs or collars and the rim inthe same manner as or similar to the spokes 4 and are arranged to cross each other near their inner ends, as more plainly shown in Fig. l; or they maybe secured in the center of the rim and in the periphery of a central hub or collar 8, as shown in the modification illustrated in Fig.

I do not wish to limit myself to any particular lmanner of fastening thc spokes in the wheel, as they may be attached the same as in bicycle-wheels, or with heads or nuts on their outer ends in the rim and with threaded inner ends to be screwed into the collar or a huh or sleeve; also, in connection with the peculiar arrangement of the spokes thus far and hereinafter described I regard any fastening for said spokesat their inner orouter 'ends as within the Scope of my invention.

On the outer faces of the hubs or collars l are securedshields or caps-9, as shown in Fig.

IOO

l., for excluding dust or dirt from the annular grooves 2 and the slots or holes G. These caps may be fastened in place by the screws l0 or by having internal screw-threads fitted to corresponding threads on the peripheries of the hubs or collars.

The inwardly-inclined central spokes l, which cross each other toward their outer ends, counteract any dishing strain upon the wheel,while the outside nearly straight spokes T, which cross each other near their inner ends, counteract any torsional strain thereon. For effecting these result-s I have found it preferable in practice to arrange the spokes e radially and the spokes 7 tangentially, as thereb)7 the entire strain upon the wheel is perfectly axial upon or in a line with the hubs or collars.

Vhile I prefer in my wheel to use radial spokes for taking the dishin g strains, and tangential or non-radialspokes for taking the torsional strains, I do not confine myself to this construction, but may use instead the construction shown in Figs. 5 and (l, in which all ot' the spokes of the wheel are tangential or nonradial, each spoke being secured at its inner end to the hub of the wheel at a point near the end of the hub and being connected at its outer end to the rim of the wheel near its edge and on the opposite side of the wheel from its inner end, the spokes crossing from one side of the wheel to the other, so that in this way the tangential spokes are able to take both torsional and dishin g strains. This construction is perhaps not so strong as my preferred con struetion,as shown in Figs. land 2, but has the advantage of being much simpler, and because of the smaller number of spokes each of these spokes may be made strongerthan in t-he first construction without undue increase in weight. For some purposes this latter construction may be sometimes preferable to the first, and I therefore eX- pressly reserve the right to make separate application for Letters Patent for the construction of wheel shown in Figs. 5 and (5.

Itis obvious that other arrangements of spokes are possible. For instance, radial spokes may be used alone for taking both dishing and torsional strains, or radial spokes may be used for taking the torsional strains and tangential or non-radial spokes used for taking the dishing strains. These latter constructions, however, I regard as essentially weaker and inferior in every way to my preferred constructions.

'Iarious means for securing the spokes to the rim and hubs or collars may be devised without departing from the spirit of my invention, and, although this construction and arrangement or combination of parts is principallyintended for vehicle,suspension,wind, and water wheels, it is evident that it may be applied to pulleys of various kinds and to other similar machine elements where combined lightness and strength are desired.

For the hubs or collars shown in Fig. 3 may be substituted a plain hub having two end fastenings and one central fastening for the inner ends ofthe spokes, such as three peripheral rows of holes drilled or otherwise formed in said hub, or any other suitable style ot' fastening within the knowledge of the or dinary mechanic may be employed.

IIaving thus fully described the construction and arrangement or combination of the several parts of my improved wheel and its advantages, what I claim as new therein isl.
