TOY BICYCLE.

'Application filed october 1, 192e. serial No. isses.

My invention' relates to toys of the vehicle class;

The invention consists of incorporating the ltoy commonly known as a scooteiz My object is to provide a toy of this description which shall be light; which may be manufactured at a low cost, and which ple in construction. Where possible, com? mercial parts used forv other purposes, are here used to save the special details that would otherwise be required. 4 .Forming a part of the frame is a relatively wide base board, to which are secured the bearings'for the/crank shaft` and the bearings for the rear wheel. F rom this base board projects the seat post, suitably braced, and the frame construction is completedby bracing -the head to this base boa-rd. The width of the base board enables me to position the crank shaft bearings so'that there -is ample room for the child tostand between the rotating crankswithout interfering with their rotation. Other innovations, not claimed as patentable will appear in the accompanying specication and the drawings forming a part thereof.` In the drawings, Fig. 1 isa side elevation of a toy embodyingv my invention, and Fig. 2 is a plan of the same. i

In the drawings, 10.is a base boardr-elatively wide, and slotted at 11 and12 to permit the rear wheel 13 and the driving pulley 14 to operate. Bearings 15 for the rear wheel and 1G-'for the crank shaft are secured to the base board, and extending upwardly therefrom is the seat post 17, rigidly braced to the base board by the member 18, which is slotted to provide clearance .for the rear wheel 13, and the driven pulley 19 rigidly secured thereto. Therear wheel 13 is rigi. 45 y idly secured to the shaft 20, which is journaledin the bearings 15, adjustable at 21y to take up the stretch of the endless belt 22 by means of which the rear wheel is driven by 'j l crank action from the pulley 14. j 50 f The driving pulley 14 is rigid with the -crank shaft 23, which is journaledin the bearings 16, secured to the base board 10, and these bearings are positioned to provide ample room between the cranks to permit the childs feet to rest on the base board 10, when coasting, or tov permit the lchild, to stand on the base board if so desired, and without interferencey with the -rotating cranks, 25. The head 26 is braced to the base board 10, by the member 27, and a supplementary brace 28, and the angle iron`29,

insures rigidity of thev frame as aunit. The forks 30 for the front wheelare integral with a single post 31, and thefwheel 32, rigid with the shaft 33, is rotatable between theV forks, the bearings 34 for the shaft 33, be-Y ing lsecured to the forks in any suitable manner. The fork member is hinged at 35 to the head 27, and from the upper end of the post 30 extend the handle bars 36.

As this article is a toy, the construction I must necessarily be simple, land permanence is sacrificed to insure a lowinanufacturing cost, as long service is not'to be expected. `75 i Having thus described my invention, I claim i* In a bicycle of the kind propelled by the ordinary sprocket and chain, a frame member, slotted to permit the driving sprocket to project therethrough, and to which are secured the bearings for thecrank shaft, so f disposed that the feet may rest on the frame y member between the cranks, one on reither side of the sprocket, without interference ,as

therewith, or with-the cranks.
