ATTORNE Patented Dec. 18, 1934 UNITED STATES- PATENT OFFICE VELOCIPEDE FRAME CONSTRUCTION Giles E. Bullock, Rochester, N. Y., assignor to E. C. Brown 00., Rochester, N. Y.

Application May 1, 1934, Serial No. 723,363 2o Claims. (01. 208-113) the frame with a single piece tubular backbone member of a large diameter in order to increase the strength thereof and permit the seat and fork support to be mounted within the tubing and also to provide a sufficient space between the seat and fork support and the inside wall of the tubing to permit electric wiring to be placed within the backbone member and extend from one end to the other end thereof.

A further object of this invention is to provide the backbone member of the frame with novel seat supporting and adjusting means.

A further object of this invention is to provide the backbone member with an extension which provides the mounting for a headlight for the velocipede.

Another object of this invention is to provide the frame with a novel platform at the rear of the backbone member and to provide a novel manner of attaching the backbone member to this platform and attaching the platform and the back member to the rear axle of the velocipede.

All these and other objects and attendant advantages of this invention will become more readily apparent from the detailed description thereof which follows, reference being had to the accompanying drawings in which Figure 1 is a side elevation of a velocipede embodying my novel frame construction.

Figure 2 is a rear elevation thereof.

In the several figures of the drawings like reference numerals indicate like parts.

The velocipede which has my new and improved frame construction incorporated therein has-the general form of a tricycle which, at the front, is provided with the fork 1, supported on the front wheel 2 and operated by the handle bars 3 and which at the rear is provided with the wheelsv4, 4 mounted on the fixed axle 5. The frame construction is made up of the large tubular single piece backbone member 6 which is preferably cylindrical in cross section at the front and thruout its central body portion but is gradually flattened out at the top and bottom toward the rear end thereof to give the sides of the backbone member a rearwardly tapering form.

The backbone member is curved rearwardly and downwardly the full length thereof and its forward end is extended beyond the fork 2 into a horizontal position to provide the mounting for the headlight 7. This headlight comprises a suitable housing 8 which is mounted to or formed on the front end of the backbone extension and is provided with a suitablereflector, an electric incandescent light and a lens together with suitable switch means with which the light may be turned on and off. In view of the fact that the particular head light construction, except the combination of its housing with an extension of the backbone member, which provides the mounting for it, does not form any part of this invention, no detailed construction of the headlight is shown. The batteries for the operation of the headlight may be located in the housing 8-or placed into the backbone membenor they may be mounted in the platform at the rear of the backbone member and connected with the headlight by suitable wiring located within the backbone member as illustrated in Figure 3.

The fork 1 is swiveled in the bearing sleeve 9 which extends thru the tubular backbone memher 8 and is suitably fastened thereinto as for example by welding the joints between the sleeve and the backbone member on the inside of the backbone member. This is made possible by the use of the large diameter backbone member which permits the forming of a welded joint within the tubing without difliculty. The use of a large diameter backbone member in combination with a bearing sleeve of considerable smaller diameter also provides space between this sleeve and the inside wall 'of the backbone member which permite electric wiring to extend past the fork with in the backbone member and thus be entirely concealed and protected within the frame construction.

As above pointed out the rear end of the back bone members is gradually flattened at the top and bottom which widens this tubular member at its point of attachment to the platform 11 and to the fixed rear axle 5. The platform is formed up of sheet metal and is provided with a large semicylindrical front 12 and a smaller semicylindrical rear 13. The

sides

14, 14 of the platform have the sleeves 15, 15 drawn inwardly therefrom and the rear axle 5 passes thru these sleeves and is preferably welded thereto. The flattened rear end of the backbone member projects thru a sleeved hole in the top of the platform and is anchored to the rear axle below the platform by having this axle pass thru the narrow semicircular sides of the backbone member and the

sleeves

16, 16 drawn in thereon and having the axle welded thereto. In addition the backbone member is also welded to the platform 11 on the underside thereof so that the weight carried by the backbone member is supported on the rear axle by the platform by means of its

sides

14, 14 which are fastened to the axle near the supporting wheels and by the backbone member itself at the point where it is attached to the middle of the axle. The rear axle can therefore support any reasonable weight carried by the backbone member without bending.

As illustrated in Figures 3 and 4 considerable space is provided on the under side of the hollow platform 11 and this can be utilized for the storage of electric drycells which are connected to the headlight entirely within the frame by means of wiring 11A which is placed into the large diameter backbone member to extend from the rear end to the front end thereof.

The support for the saddle post 17 is provided by the sleeve member 18 which, as illustrated in Figures 7 and 8, projects thru the backbone member and comprises a sleeve formed up from fiat stock into a rectangular cross section. At the upper end the sleeve member is provided with a.

lateral enlargement which projects to one side of the backbone member and holds the nut 19 In place therein. This lateral enlargement of the sleeve provides a head on the sleeve which rests on top of the backbone member so that the lower end of the sleeve when welded or otherwise fastened on the underside of the backbone member will hold the sleeve member in place in the backbone member. A set screw 20 passes thru the outer overlapping walls of the head of the sleeve member and is threaded thru the nut 20 to engage the saddle post 17 and hold this post at any desired elevation in place in the sleeve member. This form of construction secures for the saddle post a more rigid support and provides the clamping means therefore above the backbone member instead of in the middle or below the backbone member as is the case in other velocipede constructions. Furthermore the sleeve member passing thru the large diameter backbone will leave ample space between it and the inner wall of the backbone member for the electric wiring passing thru the backbone member.
