SPECIFICATION forming part of Letters Patent No. 699,756, dated May 13, 1902. Application filed March 30, 1897. Serial No. 629,942. (No model.)

To a/ZZ whom t may concern: i along line 3 3 in Fig. lgFig. 4, a longitudinal Beit known that I, CHARLES L. HORACK, a section along line 4 4 in Fig. 2; and Fig. 5, citizen of the United States, anda resident of such a section along line 5 5 in Fig. 2, where Brooklyn, in the county of Kings and State of the end of a spoke is located in such plane. 5 New York, have invented certain new and Fig. 6 shows a crosssection of another' felly useful Improvements in Wheels, of which the and parts connecting therewith embodying following is a specification. some of the leading features of my invention. My invention refers to wheels in general, In carrying out the'more important parts and more particularly to wheels to be used on of my invention I employ in the construction 6o Io light vehicles having to support only moderof the felly laminze, preferably made of wood ate loads, such as bicycle-wheels, and espeand so shaped and jointed together that becially to their fellies, tires, and spokes and tween them there will be formed one or more to the means for securing and adjusting said spaces or chambers, which should be closed parts in proper relations to each other. to the atmosphere, so as to exclude dirt and 65 The objects of my invention are to properly moisture therefrom.

Laminzectand Z beingmade larged scale, represent sections of fellies and to extend symmetrically to both sides of said connecting parts constructed according to my central plane tend to still further unite said rco 5o invention. ThusFig. 2 shows a cross-section two groups of laminze.

along line 2 2 in Fig. l; Fig. 3, a cross-section As I desire to avoid the uso, in combination with my fellies, of the large inflatable pneumatic tires now in common use on bicycle- Wheels, I give to my felly, combined with a light elastic tire,as I propose to employ,a crosssection of such depth as will insure proper strength and rigidity, and in order to at the same ti me reduce the weight ofthe felly as far as safe and practicable I provide spaces or pockets in its interior portions where the material thus abstracted would least contribute to its strength. For this purpose I provide suitable recesses and perforations in the laminze, depressions in laminze d and b together forming pockets PQ depressions in laminze @and d forming pockets P2, depressions in e and f forming pockets P3, depressions in lamin d and h, together with perforations in lamina g, forming pockets P4, and depressions in laminae i and 7c, together with perforations in laminaj, forming pockets P5.

S S aud S S' are the spokes, indicated here to be made of wire. They maybe connected with the hub H in any suitable manner, but preferably are each placed at a slight angle with the vertical central plane of the Wheel, so as to have the interior ends of alternate spokes connect with opposite ends of hub H,

vthus connecting, for instance, the interior ends of spokes S S with the right-hand end of said hub and those of the alternate spokes S' with its left-hand end. This is the arrangement now commonly employed in bicycle-wheels. As wire spokes are not adapted to resist compression to any considerable extent, it will be seen that the Weight of the rider and the vehicle where such spokes are used must principally be transferred from the hubs of the wheels through the spokes above them to the upper part of the felly and from there downward along and through said felly to the point of contact with the ground, and I accordingly so connect the spokes with the felly that every spoke at the time that the hub is suspended thereon will properly transfer the strain produced thereby upon the whole of the felly. For that purpose I pass the outer thickened portions of the spokes through lamina a as Well as through all the other laminae placed on one side of the vertical central plane only, thus passing spokes S through laminze a, h, c, d, c, and f and spokes S through laminze d, g, h, t', j, and 7c, deflecting the outer ends of the spokes sufficiently to place the same at right angles to the main joints between said laminze. Said spokes are screw-threaded at their outer ends, where flanged nuts N, resting on washers NV, engage with the same, and are also screwthreaded at a; above the points where they curve before entering the body of the felly, screw-threaded sleeves Y, made bell-shaped, so as to accommodate themselves to such curvature, resting on yielding or spring Washers V, being made to engage therewith in such manner that they may be employed as setnuts after proper tension has been imparted to the spokes through the instrumentality of nuts N.

R represents a tube or packing around the portion of the spoke within the body of the felly. The saine is preferably made of elastic material, such as rubber, and is employed to prevent the cutting of the laminze by the spoke and to moderate shocks imparted to them by the latter. At the points opposite where spokes S and S penetrate lamina f and 7c, respectively, the end of lamina lis cut out, as at z, to make said spokes and nuts N accessible.

It is important to make the body of the felly solid where the spokes pass through it, as shown in Figs. 2, 4, and 5, so as to prevent springing of the laminzc Where strain is so applied to them and to give to the spokes and their packings R a solid and continuous lateral support within the body of the felly, and this will compel either total or partial interruption of the continuity of pockets P P2, rbc. Thus in Fig. 2 pockets P and P3 appear interrupted entirely Where spoke S passes through the felly, while pocket P2 at this point appears reduced in cross-section, pockets P and P3 under these circumstances extending only within spaces between neighboring spokes S S. Similar conditions are indicated in Fig. 5 with reference to pockets Pl P4 and P5 P5. W'hile in the above-described figures the pockets on the two sides of the central vertical plane of the felly are shown to be of different configurations, they are intended to be and are proportioned so as to have the weight of the felly or of the wheel balanced with reference thereto. Generally speaking, and particularly where the laminas are symmetrical with reference to said plane, it will be well to arrange the pockets on both sides of said plane symmetrically thereto and to theaXle of the wheel as far as the location of the spokes Will permit.

T is an elastic tire of U-shaped cross-section, made of rubber, leather, or similar material and having its edges inserted in suitable grooves G upon the outer surface of lamina l, whereby a pneumatic cushion is formed between these parts, while U represents a shoe made of rubber with roughened surfaces, leather, or similar material, having a proper outer contact-surface and so cemented or otherwise secured to theouter surfaces of tire T and felly F as to cover the former completely as well as the joints between the laminze comprised in the latter. Thus said shoe will not only serve to reinforce the tire, but also to protect said joints and to contribute toward firmly tying together the laminzc in the Wheel.

In Fig. 6, m, n, o, p, and q are laminze extending symmetrically to both sides of the central vertical plane of the felly F. By perforating lamina m and grooving out the remaining laminae pockets P6, P, PS, and P9 are formed within the felly, as shown. A metal- IOO IIO

lic shoe R, with suitable head at its lower end, is shown to be inserted from the outer surface of the felly in line with spoke Sil and to be screwthreaded at its upper end interiorly to engage with the screw-threaded end of said spoke and exteriorly to engage with a set-nut Y', whereby7 proper tension of said spoke can be effected and the laminse will be rmly tied together. T is a rubber or leather tire cemented to the sides of the lower laminze and so curved and of such stiffness as to leave at all times an air space or cushion between it and lamina q and extending over the joints between laminze o, p, and q and having its upperends projeetinward into the body of the felly. Corresponding pockets on both sides of the central vertical plane of the felly-as, for instance, P5 and PT-might be consolidated and made continuous, in which case a plug Q., made of wood, paper, rubber, or the like, should be placed in a position, as indicated in broken lines in Fig. 6around tube R so as to thereby properly stay lamine m and o opposite points where spokes connect with the felly.

I do not wish to confine myself to the relative arrangements of the various parts and the details shown and described herein, as various changes and modifications may be made by those skilled in the-,art without departing from the spirit of my invention.
