Specification of Letters Patent.

Patented Feb. 8, 1916.

Application filed August 4, 1913. Serial No. 782,846.

for its object to'greatly simplify the con struction of the said wheels, to materially increase their strength, and to largely increase the resiliency of the wheels without weakening the same.

My means of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which Figure 1 is a fragmentary view of a portion of a wheel constructed in accordance with my invention. view through the center of thehub. Fig. 3

' is an enlarged detail view of the securing ring for holding the spokes in position. Fig. 4 is an enlarged fragmentary view of the outer end of the hub, part of the same being shown in section, to show clearly the manner of fastening the inner ends of the spokes and of tightening the same. Similar reference numerals refer to similar parts throughout the entire description.

.As shown in the drawin s, the hub consists of a tubular portion 1, w ich is adapted to be sqcured to the outwardly projecting end of the box 2, which latter is provided with a brake drum 3 of the usual construction. The tubular member 1 is provided with an 'outwardlyextending flange 4, which is provided with alaterally extending peripheral flange. The brake drum 3, is securedto the said flange by means of bolts. 5. These bolts can be any desired number to furnish the requisite strength. In the outer end of the tubular member 1 "I form a keyway 19, to

which is fitted a'key 6. A tubular member -7' is slidably but non-rotatably mounted upon the tubularportion 1 of the hub, the

ed to prevent its rotation.

key 6 being provi It will be obvio I at any number of these keys may be e yed to furnish the required resistance to the torque.

The tubular member 7 is provided with an outwardly extending flange 8, which has Fig. 2 is a sectional cast or formed therewith a laterally extending peripheral flange which is provided with a plurality of holes 9, through which the spokes 10 pass. The spokes are provided at their inner end with circumferential grooves 11, as clearly seen in Fig. 5. A ring 12 is located inside of each of the laterally extending peripheral flanges formed on the flanges 4 and 8. Each ring is provided with a plurality of slots 13 and 14, the slots.13

being deeper than the slots 14, the reason for which will be hereinafter explained. Threads 15 are out upon the tubular member 7, and, adapted to be engaged by internal threads cut upon a. nut .16, whichrserves to put a tension on the spoke.

, The assembly of my wheel is as follows: The spokes 10, which are provided with up set heads- 17 at their outer ends, which are adapted to engage the depressions formed in the rim 18 of the wheel, are dropped into the rim and their inner ends extending in.- sidev the peripheral flanges formed on the flanges 4 and 8, in which position the rings 12 are dropped into place, the slots engag-,

means of a spanner wrench, or if desired,

it can be made hexagonal for other forms of wrenches. The tightening of this nut brings its inner wall in contact with the end wall of the tubular ortion of the hub, and the continued rotation draws the tubular member 7 outwardly, thereby tightening the spokes, the tension of which can bemade as great as is desired.

By this construction it is posefble to, fur- 'nish a device which when employedby an unskilled workman results in the production of a wheel which is perfectly true both laterally and radially. The spokes can be drawn up to any tension and have resent in them none of the-weaknesses which are.

present in those spokes which employ threaded nipples at ei'r'outer ends.

My means of imparting an increased resiliency to the wheel will be more clearly observed in the assembled view.

It be. observed that I new extended the V e,

ou'twardlyona true radius. Then it is t tubular member having an a or curved in the sw d or up-set portion, which portion is ca culated to providea bendin moment inexcess of the strengt of a smaller portion. As this bend on the spoke isjmade on the arc of a true circle, and is designed at too slight an-angle to cause the least-crystal1izationof the ma-w .terial, the result is that the wheel 'is con-- stantlly in a state of suspension, which ma y eter than the' area of the apertures, said terial increases the resiliency thereof; Having described my invention, what I regard as new and desire to secure by Let.- teisPatent is: g l
