'7 Claims.

This invention relates to a toy vehicle that is similar in appearance and in operation to a Hyster lumber carrying truck. Such truck is adapted to straddle a load of lumber that is supported on a flat or elevated platform. Load lifting elements on the truck then engage the fiat and elevate it with its load of lumber so that theltruck supports the load. The truck then carries the load to the desired unloading point where it releases the fiat, and the load is then again supported on the ground in the same condition as before being transported.

' One of the objects of this invention is the provision of improved means in a toy vehicle of the above character for lifting and for releasing a load.

Another object of the invention is the provision' of simple and improvedmeans in a toy vehicle of the above character'for steering the four wheels'of the same simultaneously. In the full sized tr-ucksor vehicles, the load lifting andsteering mechanisms are necessarily quite complicated and would be prohibitive in expenselin a toy. In the present instance the mechanisms for lifting the load and for steering the. toy vehicle are simple, economical to make and are easy for a child to operatev Other objects and advantages will appear in the description and in the drawings.

Inthe drawings, Fig. l is a side elevational view of a toy vehicle with the steering arrangement indicatedin dash lines where hidden Fig. 2 is a sectional view taken along line z- -z arms; 1..

Fig. 3 is a sectional. 3- 3 ofFig. 1.

' Fig. 4 is a side elevational view of the load elevating system in full line with the outline of the vehicle in dash lines.

Fig. 5 is a perspective viewof one of the flats or platforms from the under side. i

In detail, the vehicle herein illustrated comprises a horizontally disposed oblong frame I that is journalled at each of its four corners for a vertically extending rotary shaft 3. The longitudinally extending sides of the frame are preferably of substantial vertical thickness with the bearing for each shaft .3 extending substantially the full vertical width at each of saidcorners s0 thata substantial bearing. is provided for each shaft 3.

A tubular open ended piece 4 that is formed in simulation of a part of the actual workin truck extends upwardly from each corner of frame I in alignment with each shaft 3, the

view taken along line the same direction;

through bore in each piece 4* being in alignment with thobearing: for each shaft. 3.:

,A screw 5 extends .througheac'htubular piece 4' and is threaded into the upper end of each shaft 3. The upperend of the. bearing for each shaft 3 is of 'reduced'diameter, as at 6, less than the'diameter of each shaft 3, thus providing a shoulder above each shaft. A coil spring 1 reacts between eachshoulder and the upper end of each shaft whereby the frame .l will be sprung on said shafts.

The lower end of each shaft 3 has a down= wardly directed fork thereon. Sides 8 of'each fork have a horizontalaxle'carried thereby at their lower ends, a'nd'a ground wheels is-rotat able on each axle. i i i a The opposed inner side Walls of the bearing at each of the' ends 'of frame i are horizontally slotted (Fig; 2) for a laterally projecting lever arm 15'. When wheels 9 are'in'parallelplanes that are parallel-with the longitudinal axisof a the vehicle, the said pair of arms at each end of the frame are in coaxial'alignment, and are con nected by a link l6 that-is also in alignment with the'lever arms. Each link-l6 is vertically 'piv oted to the end of the frame I at a point centrally between the ends fof' the link, as indicated at'l'8.'

A pin [9 on the outer end of arms l5 that are at each end of the frame I extends vertically through a slot 20 in each outer end of each link It. Slots 2 6 in eachlink extend longitudinally thereof. Q v

The pins {9 that are on the corresponding arms l5 along one of the longitudinal sides of the frame respectively extend through one of the ends of a pair of flat connecting bars 23. These bars extend toward each other from opposite By the abovestructure, revolution of the. gear will result in arms i5 24 on its vertical axis being moved to the dash line position indicated in Fig. 2. When the gear 24 is rotated in one direction the shafts 3 at one end of the frame will be rotated simultaneously withth'e shafts at the opposite end, but in an opposite direction, although the shafts of Thus a short turn maybe made by the vehicle even though the ground Wheels are turned a relatively short; distance." effected by rotation- Y Rotation of gear 24 is each pair will; be rotated of the steering shaft 29 (Fig. l), which shaft is journalled for rotation in a post 30 that is secured to frame I through the medium of a hood portion 32 that is integral with the frame, the post being on said portion. A steering wheel 33 is secured on the upper end of shaft 29, and a gear 34 is secured on the lower end of said shaft with its teeth in mesh with the teeth of gear 24. This steering shaft is inclined to correspond with the inclination of the shaft in the full sized working trucks.

In vehicles of the type simulated by the toy vehicle herein described, a load of stacked lumber is supported on a flat or elevated platform. The vehicle then moves over the load, straddling the same, and load engaging elements carried by the truck engage under the opposite edges of the fiat that extend longitudinally of the vehicle and when these elements are elevated they lift the flat and its load off the ground so they will be carried by the truck.

In the present instance, the load engaging elements comprise a pair of horizontally extending parallel angle strips 40 (Fig. 3). .These strips extend longitudinally of the vehicle, one being below one side frame member and fairly close to the ground, while the other is correspondingly positioned below the other side frame member. Angle strips 40 are so disposed that one of the sides 4| of each is vertical, while the other sides 42 are coplanar and extend toward each other.

A-pair of vertically extendingrods 43 extend vertically upwardly from the ends of each strip 40, and are secured at their lower ends to each side 4|. Rods 43 are slidable vertically in vertical passageways 44 (Fig. 2) that are cast i the side frame members of frame I Centrally between the ends of each strip 40 is a vertically extending load elevating element or member 45. Each rod 45 is secured at its lower end to each strip 40 and slidably extends at itsupper end in a guideway 41 in each side frame member of frame I. These guideways 41' are opposedly opening vertically extending grooves formed on the opposed inner sides of said side frame members.

The upper ends 48 of each rod 45 are bent to extend inwardly toward the center of the vehicle at right angles to the vertical length of each rod (Fig. 3). Journalled for rotation in the side frame members of frame I at points adjacent the upper end portions 48 of rods 45 are opposite ends 49 of a horizontally extending shaft 50. Ends 49 are coaxial and are parallel with the central portion| of shaft 50 but they are offset radially relative to the longitudinal axis of said central portion 5|. Right angle bends 52 connect the end portions 49 with central portion 5|.

The end portions 49 each have a correspondingly positioned laterally projecting member 53 extending radially therefrom below the inturned upper ends 48. When projections 53 are horizontal the right angle bends 52 of shaft 50 are vertical extending downwardly from the central portion 5|.

A handle 54 is secured at one end to the said central portion 5| of shaft 50 and is adapted toyieldably and frictionally. engage in any one of a series of notches 56 formed in one side of a slot 57 in a cross piece 60 that extends between the side frame members and that is integral with the latter. manually swung in one direction, the central When handle 54 is ,vated upon so swinging 4 portion 5| is swung upwardly and the projections 53 will raise the rods 45 with the result that the load engaging strips 4i! will be elevated. When the handle is swung in the opposite direction, the strips will be lowered.

A flat 36 of the type shown in Fig. 5 is suitable for use with the vehicle. ,This flat has portions 53 struck from the same to form means at each end for supporting the flat elevated above the ground. The lumber 64 (Figs. 1, 3)

is stacked on the fiat between upstanding flanges 65 on the latter that project from the side opposite legs or portions 63. The sides 42 of strips 40 will-engage the underside of each fiat below flanges 65 for elevating the flat and lumber thereon. Notches 56 in which handle 54 is yieldably engagedwill hold the flats elevated when a load is lifted by swinging said handle in one direction;

Movement of the handle 54 is indicated in Fig. 4, the full line position'being that in which the load is elevated, whilethe dot position is the one in which the load is released.

While there are other ways of elevating the loadand of steering the vehicle, the structure herein disclosed is preferable. The use of the gears in the steering mechanism permits easier and smoother operation than were the gear'24 to be directly rotated by a steering wheel without the use of gear 34, and also it is preferable that the steering wheel shaft be inclined to follow the standard practice. I

The use of a single lifting rod on each strip is highly desirable, using rods 43 as merely stabilizers. I a

It is to be understood that the detailed description and drawings are not to be considered as being restrictive-of the invention to the precise forms so described and shown, but they are merely illustrative of a preferred form.
