VELOCIPEDE.

Specification of Letters Patent.

Application filed January 14 1920. Serial No. 351,385.

To all whom it may concern Be it known that I, GLAnnNon W. BnN- News, a citizen of'the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Velocipedes, of which the following is a specification. I

This invention relates to vehicles of the type ordinarily known as velocipedes and has reference particularly to the wheel hub and crank structure.

The objects of the invention are to provide a simple, practical and relatively inexpensive structure of this character which can be readily assembled and particularly one in which the cranks can beeasily removed for shipment and storage purposes and which, when desired, can be as readily assembled.

The invention involves various novel features of construction, combinations and arrangements of parts, all of which will be fully described in the following specification which is to be read in conjunction with the accompanying drawing forming .a part hereof and wherein I have disclosed but one of the preferred embodiments of the invention.

In the drawing referred. to, Figure 1 is a perspective view of a childs velocipede having the features of the invention incorporated therein.

Fig. 2 is a cross sectional'view of the hub structure of the front wheel, as taken on substantially the planeof line 2-2 of F ig. 3.

Fig. 3 is a broken and longitudinal sectional view of the hub and crank assembly.

Fig. 4: is another cross sectional view taken on substantially the plane of line 4-4 of Fig. 3. v

Referring now to the several parts in detail, 5-5 designate the arms of the socalled .fork which are provided at their lower ends with suitable bearings 6 to take the journal or axle portions 7 of the cranks 8.

These cranks are interlocked or keyed to the hub structure by means ofnon-circular keying portions 9 provided at the inner ends thereof which take into correspondingly shaped seats in the ends of the hub. These seats are provided by means of a tubular member, designated 10, of noncircular cross section and shown in the illustration as flattened (Figs. 2 and 4) to fit the correspondingly flattened keying portions 9 of the cranks.

In the present disclosure this tubular member 10 is also utilized as ameans for securing the end heads of the hubs together, the ends of said tube being shown Patented Apr. 5, 1921.

as extending through non-circular openings in the end headsll and riveted or turned over at the outer faces of the same, as indicated at 12. The heads are held apart in proper spaced relation by a suitable spacmg sleeve 13 which, like the heads and tube, may be constructed of relatively light and inexpenslve sheet metal.

Spokes 14: are suitably secured to the end heads, in this instance, by overlying clampmg plates 15 which are held in place by tongues or flanges 16 extended from the heads between the spokes and bent over the outer face of the clamping platessee particularly in this connection Fig. 1. j

The cranks are detachably secured to the hub by means of nuts 17 rotatably confined to the outer endsof the hubs and engaging with screw-threaded portions 18 provided on the cranks between the journal portions I 7 and the keying ends 9 thereof (Fig. 8). For rotatably securing these nuts in place I have illustrated in the present disclosure cap plates 19 fastened to the end heads by means of inwardly struck fingers or flanges 20 extended in between the spokes and bent over the inner faces of the heads, said caps having radially projecting annular flanges 21 overlying the annular outstanding flanges 22 of the nuts. The fit of these parts is such that the nuts are centered with respect to the wheel hub and while firmly held thereto, are free to be turned by means of a suitable wrench for instance.

The construction "described provides a rigid, strong hub structure which is relatively light and inexpensive to manufacture and provides a means by which the cranks may be readily attached or detached, as required. In mounting the wheel in the fork, the wheel is centered between the arms of the fork, the cranks are entered through the bearings provided therefor and when the threaded portions of the cranks are engaged by the nuts, the nuts are turned on the hub to thereby advance the keying portions on the inner ends of the cranks into the seats provided therefor in the hub, care being exercised in the first instance to place I the cranks so that the keying portions will properly register with the seats therefor.

When the cranks are to be detached, the nuts are simply turned in the reverse direction so as to withdraw the keying portions from the key-seats in the hub.

While the above constitutes a practical and at the present time a preferred embodiment of the invention, it will be understood that various modifications may be made without departure from the spirit and scope of the invention defined in the appended 7 claims and I would furthermore have it understood that the terms employed herein are used in a descriptive rather than 111 a limiting sense, except, however, for such limitations as may be imposed by the state ;of the prior art.

What I claim is: I

1. In combination with a velooipede, a I fork provided with bearings, a wheel in said fork, a hub for the wheel, said hub having non-circular seats in the opposite ends thereof, cranks hav ng non-circular end portlons :for interlocking engagement in said'seats, screw-threaded portions on the crank, our

nal portions on the crank for engagement with the bearings, and nuts rotatably con fined to the opposite ends of the wheel hub and engaging the threaded portions of the cranks to draw the inner ends of the cranks finto the seats in the hub and the journal portions into the bearings in the fork.

2.111 a velocipede, a wheel hub having non-circular seats in the opposite ends of the same, cranks having non-circular end portions for keying. engagement in said seats, the cranks being provided with screwthreaded portions, and nuts rotatably confined to the ends of the hub and engaging the screw-threaded portions of the cranks to force the ends'of the cranks into the seats end portions, cranks having non-circular aforesaid. V

3. In a velocipede, a wheel hub having non-circular seats in the opposite ends thereof, bearing members having journal portions, cranks provided with screw-threaded portions, non-circular end portions on the cranks for engagement in the seats aforesaid, and nuts rotatably confined to the ends of the hubs and engaging the strew-threaded portions of the cranks.

4. In a velocipede, a wheel hub having end heads, a tubular member extending be tween said heads'and having non-circular end portions fitting in the'non-circular end portions of the tubular member, said cranks being provided with screw-threaded por tions, and nuts rotatably confinedto the end heads and engaging the screw -threaded portions of the cranks.
