MOVABLE PLATFORM.

Specification of Letters Patent.

Patented Apr. 13, 1920.

Application filed November 3, 1919. Serial No. 335,463.

To all whom it may (on cam Be it known that I, ALBERT H. LnvnNi-i, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Movable Platform, of which the following is a specification.

It is now the practice in up to date manufacturing plants for the workman at the different machines to stack the finished articles on movable platforms and when a platform is full an elevating truck is passed beneath it and the platform with its contents is removed to a desired point of utilization. These platforms as heretofore constructed have been made to fit the heights of the different elevating trucks on the market and as it frequently happens that different factories have difierent types of elevating trucks, which can be only used with platforms of special types or sizes, it is necessary for a factory to purchase platforms which can be used with the special type of elevating trucks which they have on hand.

It is the object of my present invention to devise a novel construction of a movable truck platform which can be readily adjusted to any desired height of platform truck and also readily adjustable to suit the character of the material which is to be handled, which can be quickly and readily converted from an ordinary platform type into a skeleton type of truck adapted to carry shelves or into one having a closed front and rear or into one of the box type of construction.

With the above in view my present invention comprehends a novel construction of a truck platform wherein the parts are constructed and assembled in a novel manner and wherein the supporting legs or standards are adjustable so that the height of the platform from the floor may be varied in accordance with conditions and requirements met with in practice.

It further comprehends a novel construction of a truck platform having corner stakes adjustably connected therewith and provided'with a novel construction and arrangement of shelves which when unfastened at specified points can be lowered to form closed sides on the truck platform.

Other novel features of constrpction and advantage will hereinafter more clearly appear in the detailed description of the invention.

For the purpose of illustrating my invenwhich in practice will give satisfactory and reliable results. It is, however, to be understood that these embodiments are typical only and that the various instrumentalities of which my invention consists can be variously arranged and organized and that the invention is not limited to the preelse arrangement and organization of these lnstrumentalities as herein set forth.

Figure 1 represents, in perspective, a truck platform, embodying my invention.

Fig. 2 represents, in perspective and in detached position, the framework which supports the truck body on which the articles are placed.

Fig. 3 represents, in perspective, the truck platform having the corner angled and adj ustably connected therewith.

Fig. 8 represents in perspective, the platform truck provided with front and rear plates and with shelves.

Fig. 9 represents, in perspective, the construction seen in Fig. 8 with the shelves dropped to form a box type of platform.

Fig. 10 represents a section on line 10-10 of Fig. 8.

Fig. 11 represents a section on line 1111 of Fig. 8.

Fig. 12 represents an elevation showing the manner in which the trucks can be stacked.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

The truck is provided with a framework which consists of a rectangular or other shaped frame 2 formed preferably of structural metal such as for example a single angle bar which is bent into the desired shape and has its free ends connected together by welding, riveting or any other desired manner.

3 designates the body of the truck platform which preferably consists of a sheet metal plate having the corrugat ons 4, the marginal edges of this plate resting 011 the bottom flange of the angle which forms the frame 2 and is secured thereto by rivets or other fastening devices 5, see more particularly Fig. 10, said fastening devices bemg located in the corrugations so that the body 3 will present a flush surface. In order that dirt' or foreign material which collects in the corrugations 4 may be readily removed, I provide one or more apertures 6 in the bottom of such corrugations. F ixedly secured to the corners of the frame 2 by means of fastening devices 7 are the depending brackets 8 which have the apertures 9 formed in them so that the adjustable corner angles 10 can be adj ustably connected therewith by means of fastening devices 11 such as for example bolts and nuts which pass through desired apertures 12 in the angles 10.

It will be apparent that by connecting the standards formed by the angles 10 to the truck platform so that they can be readily adjusted, the height of the body 3 from the floor may be varied to suit different height platform trucks. The corner standards formed by the angle 10 may extend to any desired height above the body 3 and the apertures 12 are formed in each face of the angle and preferably extend in spaced relationship from the bottom to the top thereof so that they can be adjustably connected to the body portion of the truck platform, and also so that they can be properly braced by means of cross angles or bars 13, see Fig. 4. lVhenever desired a front plate 15 and a rear plate 16 is connected to the angles 10 by means of fastening devices 17, as will be understood by reference to Fig. 4.

It will thus be seen at any time desired the front plate 15 and the rear plate 16 can be removed and it will be apparent that one or more of such front and rear plates may be employed in accordance with the character of the material.

18 designates the shelves any desired number of which may be employed and for convenience of illustration, I have shown a plurality of shelves as being employed. The detailed construction of these shelves will 'be best understood by reference to Fig. 11 from which it will be seen that the outer side flange of a shelf is bent upwardly as indicated at 19 while the opposite side flanges 20 and the end flanges 21 are bent downwardly in order to reinforce the construction. The shelves are pivoted to the juxtaposed corner standards 10 by means of fastening devices 22 and at the central portion of the truck they are secured to the cross angles 13 by means of removable fastening devices 23. If the fastening devices 23 are removed the shelves 18 will swing into the position seen in Fig. 9 and a box type of truck platform will be formed.

Any desired number of shelves may be employed so that certain of these shelves may have the function of forming sides of a compartment while other shelves can be secured in a horizontal position and have the function of shelves.

Each adjustable corner angle has connected to it a foot piece 24 which consists of an angle or casting seated within the flanges of a corner angle and riveted bolted or otherwise connected thereto. lilachi foot piece is off-set as at 25 and terminates in a rounded bottom plate 26 which serves as an antifriction device in case the truck platform is to be moved along the floor and this bottom rounded portion 26 is apertured as at 27 in order to enable it to receive the shank of an antifriction ball or roller casting or a caster of any desired type, it being understood that when such casters are employed the truck platform becomes a combined truck and truck platform.

It will be understood that in accordance with my present invention each corner angle is provided with a. foot piece so that the corner angles will not cut into the floor or foundation when the platform is loaded.

It will be clear from the foregoing that in :wicordanee with my present invention the corner angles are adjustably connected with the truck platform in such a manner that the body of the platform will be at the proper height from the ground so that the elevating truck which the individual has in his able platform. The movable platform can thus be used with any desired height of elevating truck.

()wing to the novel construction and arrangement of the foot corner angles of the movable platform, the platforms can be stacked one above the other when desired as will be readily understood by reference to F ig.' 12.

In accordance with my present invention the superstructure of the movable platform can be readily converted from a superstructure consisting simply of corner angles into one of racks. one of shelves or the shelves can be adjusted so that a box type of superstructure can be readily provided with a minimum amount of labor.

'hen the trucks are stacked one above the other it will be apparent that the foot pieces of an upper platform will interlock with the angles or with the body portionof an under platform so that. a rigid construction will be provided.

superimposed plant can be used with the movpieces carried by the or otherwise Secured to the brackets 8. The

purpose of the guide angles is to guide the elevating truck as it is moved under the truck 'latform.

While have preferred to show the body portion or table of the truck platform consisting of a corrugated steel plate, it will be understoodthat it is within the scope of my invention to employin lieu of this i platform.

corrugated plate a fiat steel-or other plate and in many cases in practice wooden boards or planks are employed. The upper face of such plate or board is preferably below the upper face of the angles forming the framework, so that the upper flanges of such angles will serve to prevent displacement of the material placed on the truck If a corrugated plate or its equivalent is employed the fastening devices are preferably placed in the corrugations so that the upper face of the plate will present a flush surface.

It will now be apparent that I have devised a new and useful construction of a movable platform which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which will give in practice satisfactory and reliable results, it is to be understood that such embodiments are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacr1- ficing any of its advantages.
