BACKBONEFOR A VELOCIPEDE Filed June 24, 1955 Y TT /P/vfy /Qcn Patented Sept. 14, 1937 'UNITED STATES PATENT OFFICE Application June 24, 1935, Serial No. 28,035

18 Claims. (Cil. 208-113) This invention relates to an improvement in a backbone-for a velocipede and has for one of its principal objects the provision of means for forming a backbone of two stampings.

Another and further important object of the backbone of this invention resides in the provision of means for crimping the head bushing over the edges of the stampings.

A still further important object of this invention resides in the fact that a grooved member is positioned'on the head of the backbone to assist in securing the edges.

A still further object of importance and advantage resides in the provision of means for forming the edges of the stampings so they may be either welded or riveted together.

Still another object of importance resides in the provision of means for securing the rear end of the backbone to an axle supporting housing.

Additional objects of importance and advantage will be apparent from the following specication and the accompanying drawing, which show the preferred embodiment of this invention.

In the drawing:

Figure 1 is a side elevation of the backbone of this invention.

Figure 2 is a top plan view thereof.

Figure 3 is a bottom plan view of the backbone.

Figure 4 is a slightly enlarged sectional view taken on the line 4-4 of Figure 1.

Figure 5 is arslightly enlarged vertical section taken on the line 5-5 of Figure 3.

Figure 6 is a slightly enlarged view of the head portion of the backbone with the grooved member removed.

Figure '7 is a sectional view taken on the line 1-1 of Figure 1.

As shown inthe drawing:

The reference numeral I0, indicates in a general way the backbone of this invention which, in the preferred embodiment, is constructed of a right hand stamping I2, and a left hand stamping I4, joined together.

The rear portion I6, of each stamping is turned outwardly and the top portion thereof is perforated I8, as is best shown in Figures 2 and 3.

The central longitudinal portion of each stamping is substantially semi-oval in cross section with the upper and lower portions thereof flat and adapted to be secured together as is best shown in Figure 7.

Positioned along each edge and parallel thereto is a plurality of holes which when the stampings are brought together register and are adapted to receive rivets 20, for securing the stampings in position,- as is clearly shown in Figures 1, 4 andv 6. It will be obvious however, that any vother suitable means may be employed for this purpose.

VA portion of the fiat part of each stamping I2 and I4, intermediate the ends is curved outwardly to form a seat-post-receiving aperture 22.

Positioned in the forward portion of the backbone I0, is a steering-post-receiving bushing 24.

The aperture for receiving the bushing being i0 formed bycurvingthe flat portion of the stampings I2 and I4, outwardly.

The bushing 24, is secured in position by crimping each end thereof over theadjacent edges of the stampings as is clearly shown in Figures 1'5 5 and 6;

A portion of each stamping forward of the bushing 24, is flat, as is indicated by the reference numeral 26, Vand preferably perforated as is best'shown in Figure 6. In the preferred `construction of the backbone of this'invention rivets 28, are used for securing these portions to'- gether, although it will be apparent that spot welding or any other suitable securing means position on the backbone. Portions of the lower edges of the member 30, are turned inwardly as is indicated by the reference numeral r34, and are adapted to contact the crimped edge of the bushing 24, and the forward portion of the backbone. The rear portions of the member 36, extend along the sides of the backbone to which they are secured, preferably by spot-welding. It will be apparent that the-member 3l), when positioned on the backbone I0, greatly enhances its appearance and also increases its strength.

It will be further apparent that herein is provided a sectional backbone of great rigidity and exceedingly light in weight which because of its peculiar construction is exceptionally long lived.

Moreover it will be obvious from the construction shown in the preferred embodiment that the sections may be either spot-welded or riveted together. I Y

lI am aware that many changes may be made and numerous details of construction varied throughouta wide range without departing from the, principles of this invention and I, therefore,

do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

I claim as my invention:
