STOLL, 0F CLEVELAND, OHIO CHILDS WALKING DEVCE Application led November 16, 1328.
lThe object of this, my present invention, is the provision of a simple, cheaply constructed but thoroughly efhcient device for assisting babies in walking.
A further object is the provision of a device for this purpose that includes a front portion that has wheels journaled thereon, a rear portion that is provided with shoes, an upper portion that is provided with handles t0 be grasped by the infant, the shoes beingspread a suitable distance away from each other so as not to interfere with the walking of the infant, the shoes servingv as means for retarding any undue or unnatural rapid movement of the infant in a forward direction but are of a construction as to not interfere with the normal forward walking of the infant and likewise prevent the tilting of the vehicle in any direction and consequently overcoming` any liability of the infant falling as long` as his hands are arranged upon the handles.
To the attainment of the foregoing objects and others which will present themselves as the nature of the invention is better understood, the improvement resides in the construction, combination and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.
ln the drawings:
Figure l is a perspective view of the improvement.
Figure 2 is a rea-r elevation thereof.
Figure 3 is a substantially vertical longitudinal sectional view therethrough.
lligure l is a sectional view approximately on the line i of Figure 3.
ln carrying out my invention I preferably provide a downwardly inclined plate 'in the nature of a board l to whose outer or lower end is fixed an axle 2, and on the spindles of this axle there are journaled rollers 3.
The upper corners of the board or plate l are notched, and in these notches there are received the angularly disposed leg portions 3 of the improvement. The legs are in the nature of metal plates or straps and have their upper ends rounded upon themselves and connected to the plates proper. rllhrough these rounded ends t there is passed Serial No. 319,982.
a handle 5, the said handle being secured by means 6 in the rounded portions of the legs. rlhe outwardly disposed angularly arranged legs are connected directly to the upper end of the plate or board l by means 7, and the said legs have secured thereto the ends of the U-shaped or bail member 8 whose central portion is fixed, as at 9, to the board or plate l. rlhe lower ends of the legs 8 are rounded upon then'iselves and the said rounded portions have their ends secured to the plates proper. rl"hese rounded portions, indicated by the numeral l0, provide the shoes of the improvement. By reference to the drawings it will be seen that the shoes are comparatively wide and while offering but little resistance to the vehicle when the same is propelled by the infant in a forward direction at a normal speed, a pressure by the infant upon the handles will cause the shoes to bite into the ground surface and thereby restrict any rapid forward movement of the vehicle. rl`he spread legs provide ample space for the feet of the infant and likewise the said legs will prevent any liability of the vehicle moving' either in a` sideways or vertical direction. lilith my improvement it will be apparent that an infant will quickly and easily attain the knowledge of walking without any undue strain upon the legs of the infant and without any liability of injury to the infant.
ltlaving described the invention, l claim: An infants walking device comprising an angularly disposed plate having an axle fixed on the lower end thereof, and having gro-und engaging rollers journaled on the spindles of the axle, said plate having` its upper corners notched, angularly disposed plates providing legs received in the notches, upper and lower securing means between the legs and plate, said legs having their upper ends rounded, a handle received through said rounded portions and lined thereto, the lower ends of the legs being rounded upon themselves and having their ends fixed to the legs proper, the said rounded portions providing ground engaging shoes.
ln testimony whereof l aflix my signature.
