TOY TRACKLAYING TRACTR.
Application lcd August 2G, 1924. Serial No. 733,126.
This invention relates to toys ofl the class known as pull toys adaptcdto be pulled by means of a string or the like or to be pushed by the hand and the chief object of the invention is to provide a toy of this character which is novel, amusing, and at the same time of strong and rugged construction, and is adapted to be pushed or pulled over rough or soft ground.
The accompanying drawings illustrate embodiments of my invention and referring thereto:
Fig. l is a plan view.
Fig. 2 is a partly sectional elevation.
Fig. 3 is a rear elevation,
Fig. 4 is a transverse vertical section tlirough one of the Wheels and the corresponding traction belt.
Fig. 5 is a section through adjacent elements of the traction belt on line 5 5 in Fig. Il. y
Fig. 6 is a perspective of one of the elements of the traction belt.
My invention. comprises a body or frame member l which may be provided with any suitable super-structure resembling that of a commercial tractor for example a hood portion indicated at 2 land a seat indicated at mounted for example on a support 4 on the main body member l. lWheels 5 may be mounted on shafts 6 extending through body member 1 near the front and rear ends thereof.
The novel feature of my invention comprises a traction belt adapted to extend. over wheels 5 on each side of the device and to form an endless track upon Which said Wheels run. Said traction belt may comprise a plurality of traction elements 7, each of said elements comprising a flat central or web portion 8 adapted to engage. the peripheries of the wheels 5 and having a flat traction surface 9 adapted to engage the ground or other surface over which the toy moves and inwardly projecting side portions l5, each adapted to engage the sides of Wheels 5 so as to embrace the same and re tain the belt in position on said Wheels. As indicated in Figs. 3 and 4, l prefer to form the Wheels with substantially vertical side faces and to incline the inner faces of the side portions outwardly so as to miniinize surface Contact between said inner faces and the side faces of the Wheels. Said elements 7 may be Supported and joined together by means of suitable supporting means, said supporting means for each element comprising for example a link consisting of a Wire l0 bent in U-shape as indicated in Fig. 5. Each of said connecting and supporting members thus comprises a transverse portion l1 at one end of an element 7 and lateral portions 12 with which said element engages in any suitable manner; for example said side portions may extend in grooves 13 at the respective sides of said elements. Said side portions of the connecting Wires are further provided at their ends with hooks or eyes lil adapted to flexibly engage the portion ll of the adjacent connecting means. rlfhe series of interconnecting` U-shaped supporting members thus form in reality a chain or belt, upon which the traction elements are supported, by engagement of grooves 13 with the side portions of the con-` necting Wires or in any other suitable manner. As shown, I prefer to mount a single traction element on each of the supporting` links.
The above described toy may be made of any suitable material, for example, metal, although for simplicity of construction and in order to provide for necessary strength in conjunction with lightness I prefer to make the body, superstructure, Wheels and elements of the traction belt of Wood, shaft 6 being of any suitable metal for example brass and the connecting Wires 10 consisting` of iron, steel or other Wire. ln order to provide a good bearing for the Wheels so as to facilitate the turning of the same I prefer to provide each Wheel 5 With a metal sleeve or bearing 16 through which shaft 6 extends and suitable means may be provided for retaining the Wheels in position upon the shaft for example said shafts may be threaded at their ends as at l? and provided with retaining nuts 18.
Suitable means such as a hook or eye 20 may be provided at the front end of the toy for attaching a string or other means by which the toy may be pulled.
ln the operation of the toy, for example upon being pulled yor pushed alongv the ground in the manner above described, the traction belt rides over the respective Wheels and the portions of said belts which rest upon the ground underneath Wheels 5 form a track upon which said Wheels run. The
