VELOCIPEDE FRAME Filed Jan. 28, 1935 Patented Sept. 1, 1936 oNirEo srgrss rotante PATNT @FFHQE 19 Claims.

"This invention relates to an improvement in a sheet metal velocipede frame and has for one of its principal objects the economical production of an article of the class referred to which is rugged and sturdy and which readily lends itself to assembly with various sizes of wheels.

AA further important object of this invention resides in the provision of means for extending the rear end of the oor plate member upwardly 10` and through the backbone.

Another and still further important object of the frame of this invention resides in the provision of means for securing a seat thereto.

Still another and further important object of this invention resides in the provision of means for securing and maintaining the lower edges of the frame in spaced apart relation. d

An additional object of importance resides in the fact that the lowered cost of production of the frame of this invention is due to limiting the "number of operations usually found necessary in a stamped frame, and not by the substitution of lighter or cheaper material.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description.

The invention, in apreferred form, is illustrated in the annexed drawing and hereinafter more fully described.

In the drawing:

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

Figure 2 is a top plan view thereof.

Figure 3 is a bottom plan view of the frame andV shows the relative positions of the securing tongues and oor plate.

Figure 4 is a side elevation of the upright portion of the iloor plate member.

Figure 5 is a front view of a portion of the iioor plate'member taken on the line 5-5 of Figure 4, looking in the direction indicated by the arrows.

Figure 6 is a sectional view taken on the line 6 6 of lFigure 2.

Figure '7 is a sectional view taken on the line 'I--l of Figure 1. Figure 8 is a sectional view taken on the line 8-8 of Figure 1. A v

. As shown in the drawing:

-The reference numeral l indicates in a general way the backbone of the frame of this invention, which is substantially U-shaped in cross section, which includes a head i2; outwardly and rearwardly disposed axle supporting members I4,

which are also substantially U-shaped in cross section; and step plates l5.

The entire frame is formed of a single stamping, with the head l2 drawn down to form a solid front. l

The lower edges of the frame are spaced apart and portions thereof are turned inwardly to form a flat surface 22. Centrally located in the upper surface of the head l2 is a draw necked aperture I8, which is adapted to receive a steering post.

A tongue 20 formed of a portion of the backbone and extending upwardly and rearwardly therefrom forms a member for securing the front end of a saddle or other suitable seat to the frame.

Secured to portions of the lower edges of the U-shaped frame is a iioor plate member 28, the forward portion 24 thereofI having an upturned edge 25, adapted to contact the outer surface of the head l2, and also being apertured as shown by the reference numeral 25 to receive a steen ing post. The central portion of the floor plate member is slightlyraised and has downwardly turned edges 29 which allow this portion of the member to be secured within the frame IU as is clearly shown in the drawing. The rear portion 30 of the iioor plate member 28 extends upwardly and through the frame l0 as is best shown in Figures 1 and 2. The extreme end 32 of the portion`3il is horizontal and is adapted to receive and support the rear end of a saddle or other suitable seat.

Formed of a portion of .the member 30 and extending rearwardly is a tongue 34, which is adapted to be secured to the'bottom surface of the backbone I0.

The edges of the outwardly and rearwardly extending axle supporting members I4 are secured in'spaced apart relation by tongues 36 which are formed of portions of the inner edge and which are secured preferably by welding to the iiat surface 22.

Aligned draw necked apertures 38 adjacent the rear end of the frame are adapted to receive an axle.

The step plates I6 are joined to the rear portion of the frame by webs 40. The web and step plate members being an integral part of the stamping, provide a `reenforcing element which prevents the ends of the axle supporting member ill from spreading or getting out of alignment.

Apertures l2 may be provided in the floor plate member 28 .to facilitate assembly.

fiol

It will be apparent from the foregoing that herein is provided a velocipede frame which, because of its construction of a single piece of sheet metal, may be economically manufactured.

Moreover, it is sturdy and rugged and, while being considerably lighter than the ordinary sectional frame, will wear much longer and withstand greater abuse.

I am aware that many changes may be made and numerous details of construction varied throughout .a 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.
