VELOCIPEDE FRAME MEMBER Filed July 1, 1935 //1 new 70/? Patented Aug. 31 1937 UNITED STATES PATENT OFFICE I 2,091,938 I L I VELOCIPEDE FRAME MEMBER, 5'

Bert J. Anderson, Hammond, 'Ind. v I Application July 1, 1935, Serial No. 29,220

9 Claims. (01. ans- 113) I This invention relates to an improvement in a velocipede frame andhas for one of its principal objects the construction of aframe comprising a backbone and. a rear end portion including fenders which are constructed of sheet metal.

Another and further important object of the invention relates to the method of forming the outer ends of the transverse rear end portion to cover the rear wheels of a velocipede.

Still another and further important object of the frame of this invention resides in the fact that the rear lower end of the channel member is-joined to the fiat cross member. I A still further important'object of the invention resides in the cross'member which is secured to theinner forward surface of the transverseportion to prevent damage to the frame from torsional strain. 1

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

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

In the drawing:

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

Figure 2 is a rear elevation thereof.

Figure 3 is a top plan view of the frame.

Figure 4 is a sectional view taken on the line 44 of Figure 3.

Figure 5 is a bottom plan View of the frame, showing a slight modification.

Figure 6 is a sectional View taken on the line 6-6 of Figure 1.

As shown in the drawing:

The reference numeral I indicates in a general Way the backbone portion of the frame of this invention. In the preferred embodiment of the invention the backbone is curved longitudinally and is substantially U-s'haped in cross section.

Located in the forward upper surface of the backbone i0 is an aperture I2 having downwardly turned edges to form a wide drawneck bearing surface. I

Formed at the rear of the frame and being an integral thereof is a transverse portion l4 having downwardly turned front and rear edges l6 and I8, respectively.

In the preferred embodiment of the invention each end of the transverse portion I4 is curved upwardly, as is indicated by the reference numeral 20, and thence downwardly to form a fender 22, or a portion of a fender on eachend of said transverse part. It will be-obvious that this construction may be carried out by using more than one stamping.

The modification shown in Figure show the preferred method of attaching a fender skirt 23 to the transverse part M to form an integral part thereof. A drawneck aperture 25 is formed near the lower edge of the fender or 10 fender skirt. I I

Secured to the inner surface of the forwardly extending part Ii] and extending along and parallel to the lower edges thereof is a. channel member 24 which provides a means for maintaining the sides of said part in spaced apart relation. The channelmember 24 may be secured to the backbone by riveting, welding, or in any other suitable manner.

Located adjacent the front end of the channel member 24 and in alignment with the aperture I2 is a drawneck post receiving aperture 26. The edges of the aperture 26 are turned downwardly, as is best shown in Figure 4, to provide a wide span between the bearing surface of the aperture l2 and the bearing surface of the aperture 26.

Secured to the inner surface of the downwardly turned front part of the transverse portion is a. fiat cross member 28 to which is secured 30 the downwardly and rearwardly extending end of the channel member 24.

It will be apparent from the foregoing that herein is provided a sheet metal velocipede frame consisting of few parts; is practically seamless and is rugged and sturdy.

Moreover, because the body of the frame, consisting of a longitudinal part and a transverse part, may be constructed of a Single piece of sheet metal it may be economically and quickly produced in large quantities.

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 is necessitated by the prior art.

I claim as my invention:

1. A sheet metal velocipede frame comprising a stamping having a restricted forwardly extending part having downwardly turned sides, and a transverse part having downwardly turned front and rear edges, a flat cross member secured to the forward portion of said transverse part intermediate the ends thereof, and a channel member positioned between said downwardly turned sides, said channel member extending rearwardly and being secured to said flat cross member.

2. A sheet metal velocipede frame comprising a stamping having a restricted forwardly extending part having downwardly turned sides, said sidesbelng spaced apart, and a transverse part having a fender member on each end thereof, a flat cross member secured to the downwardly turned portion of said transverse part, and a channel member positioned between said downwardly turned sides.

3. A sheet metal velocipede frame comprising a stamping having a restricted forwardly extending part having downwardly turned sides, said sides being spaced apart, and a transverse part having downwardly turned front and rear edges and a fender member on each end thereof, aflat cross member secured to the downwardly turned portion of said transverse part, and-a channel member positioned between said downwardly turned sides.

4. A sheet metal velocipede frame comprising a stamping having a restricted forwardly extending apertured part having downwardly turned sides, said sides being spaced apart, and a transverse part having downwardly turned front and rear edges, a flat cross member secured to the downwardly turned front edges of said transverse part, and an apertured channel member positioned between said spaced apart sides, said apertures being in alignment.

5. A sheet metal velocipede frame comprising a stamping having a restricted forwardly extending part having downwardly turned sides and a transverse part having downwardly turned front and rear edges and a fender on each end thereof, a flat cross member secured to the downwardly turned front portion of said transverse part and parallel to the edge thereof, and means for securing the downwardly turned sides of the forwardly extending part in spaced apart relation.

6. A velocipede frame comprising a stamping having a restricted forwardly extending backbone portion, said portion being substantially U-shaped in cross section, and a transverse part having downwardly turned edges, said transverse part having a fender on each end thereof, a flat cross member secured to the under surface of said forward edge, and means for maintaining the edges of said U-shaped backbone in spaced apart relation.

7. A velocipede frame comprising a stamping having a backbone portion the forward portion of which is of restricted cross-section, said frward portion being substantially U-shaped in cross section, and a transverse part having a fender on each end thereof, and means for maintaining the edges of said U-shaped portion of the backbone in spaced apart relation.

8. A velocipedeframe comprising a stamping having a restricted forwardly extending backbone portion, said portion being substantially U- shaped in cross section, and a transverse part having downwardly turned ends, said downwardly turned ends being adapted to support a fender skirt, a fender skirt secured to each downwardly turned end and forming an integral part of said transverse part, and means for maintaining the edges of said U-shaped backbone in spaced apart relation.

9. A sheet metal velocipede frame comprising a single stamping the forward portion thereof comprising a backbone substantially U-shaped in cross section, the rear portion of said stamping extending outwardly to form a transverse part, a fender on each end of said transverse part, means adapted to maintain said fenders in alignment, and a channel member secured to the edges of said backbone.
