WHEEL.

SPECIFICATION forming part of Letters Patent No. 369,874, dated September 13. 1887.

Application filed July 10, 1895. Serial No. 171.240.

To all whom it may concern:

Be it known that-I, JOHN F. PAOKER, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Hubs and Wheels, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the complete wheel, and Fig. 2 an edge elevation of the complete wheel; Fig. 3, a side elevation of the hub; Fig. 4, a longitudinal section of the hub with two spokes in position and broken off; Fig. 5, an inner end elevation of one of the I5 hub-sections; Fig. 6, an outer end elevation 'of one of the hub-sections with a spoke in position and broken off; Figs. 7 and 8, inner end elevations ofthe two hub-sections,sl1owing the locking lugs and recesses; Fig. 9, a detail in section of the inner end of one of the hub-sections; Fig. 10, adetail in elevation ofa hubsection at the inner end; Fig. 11, a detail of a spoke, showing the hub end thereof.

This invention relates to that class of wheels which are known as suspended, and-has for its objects to give the required tension or strain to the spokes to resist the pressure in use and hold the parts firmly together, and to secure the spokes into the hub and tire in an 0 efficient and reliable manner, and to improve generally the construction of this class of wheels; and its nature consists in the several parts and combinations of parts, hereinafter described, and pointed out in the claims as new.

In the drawings, A represents one of the hubsections, having its inner end provided with a flange, A, formed by cutting away a portion of the periphery of the hub, as shown in Figs. 4 and 10, and on the inner end of the portion cut away is formed a series of rectangular lugs, a, alternately with rectangular recesses a, as shown in Figs. 3 and 10.

B is the other section of the hub, having at its inner end a flange, B, formed by cutting out a portion of the interior of the hub around the axle-opening, so that when the two sections are together the flange B will fit over and around the flange A, as shown in Fig. 4, and the end of the flange B is provided with a series of rectangular lugs, b, alternately (No model.)

cesses a, so that when the two sections AB are brought together to make a complete hub the lugs a will enter the recesses b and the lugs 12 will enter the recesses a, thus firmly locking the two sections together, and this lock will come at or near the center of the hub longitudinally, so that when the tire or rim is in place it will properly center with the hub and with the division centrally of the hubsections.

0 is a flange formed nearthe outer end ofeach hub-section, and, as shown,this flange is formed ofa series of raised ribs, 0, with a space between them, the ribs running inward on the hub-section, so as to give great strength to the flange. This flange is divided by the flanges at the inner end only, the outer end being a continuous rim around the hub-section, and between the flange O and the end of the hubsection is a cavity or depression, 0, to receive the head or hub end of the spokes. This flange is cast or formed with the hub-sections,and,as shown, the outer ends,A and B, of the respective hub-sections project beyond the plane of the flange, and in the spaces between the ribs are holes c,for the passage of the body of the spokes. The hub-sections with the flanges may be cast from malleable iron or-other suitable metal, and the section A is provided with a central longitudinal hole, A and the section B with a corresponding hole, B which holes,when the hub is together, formthe hole for the passage of the axle or trunnion.

D represents the spokes, made of wroughtiron or other suitable material and provided at their inner or hub end with a T or cross head, D, which, when the spoke is in place, lies within the cavity (1 of the flange C, as shown in Fig. 4, and the outer end of the spoke is connected to a rim, E, by a rivet-head or as shown in Fig. 1, and also have the proper 'rim,and there firmly secured by riveting. The

other section of the hub is then placed in position and the spokes passed through the holes 0' of that section to bring the heads within the recess or cavity 0' of such section, and the outer or tire ends of such spokes are passed through their openings and secured firmly by .a rivet-head, and in this operation the hubsections are not made to interlock, but the lugs a b of the respective hub-sections abut against each other,spreading the hub-sections apart to the depth of the lugs and recesses; and when the tire ends of the spokes have been firmly secured by riveting or otherwise the hub-sections are turned, so that the recesses and lugs will interlock, as shown in Fig. 3, and such turning of the hub-sections gives the required cross and tension for the spokes on opposite sides to resist fore-and-aft strain, while the stagger of the spokes from the flanges to the rim gives the required strength to resist side pressure, and the two hub-sections, when sprung together,are held interlocked by the draw of the spokes.

The width of the lugs and recesses on the inner ends of the hub-sections will vary more or less, according to the size of'the hub and wheel, and when the spokes are inserted in the hub-sections and secured in the rim or tire and the hub-sections sprung together a very compact wheel is produced, and one which will resist fore-and-aft and side strain, as, the ends of the spokes in the hub being loose,the resistance on one side will be counteracted by the resistance on the opposite side.

It will be understood that I do not herein claim the construction claimed in Letters Patent No. 323,44l,granted to me August 4, 1885, and my present invention differs therefrom in the specific combination of parts hereinafter set forth.

What I claim as new, and desire to secure by Letters Patent, is-- l. A hub formed of two substantially equal sections, each section having upon its inner end a flange and alternating rectangular lugs and recesses adapted tointerlock with similar lugs and recesses on the other section, and being provided upon the outer end with a spokereceiving flange, substantially as described.

2-. A wheel composed of the hub-sections A B, each having alternating and rectangular interlocking lugs and recesses on its inner end, and a spoke-retaining flange, O, on its outer end, strengthened by flanges c, the headed spokes D, inserted through holes 0, and the rim E, substantially as described.
