EDWARD H. POLK, or SACRAMENTO, CALIFORNIA PORTABLE PLATFORM FOR LIFT TRUCKS Application filed June 5, 1928. Serial No. 282,949.
My invention relates to portable plat-forms horizontality, "enabling the lift truck to freeof a type used in machine shops for receiving ly pass under it. On account of the free cirhot objects; said platforms being so conculation of air about and through the tubes, structed as to enable a lift truck to-be' run they do not become unduly hot, and they give 5 in under and to jack them up for ready transthe top rigidity. An inclosing border frame 5 portation about the shop. I 3, indicated in dotted lines, may be used when 'As commonly constructed for use, for ex-. nejessary. It is lightly fitted-upon the legample, in railroad shops, such platforms comframes around the top members 2; prise a pair of spaced leg-frames, and a me- I claim tallic plate or sheet carried by said frames. A portable platform' for lift-trucks com- Itis found that said plate, under the weight prising a pair of spaced le'g' frames each and heat of the objects placed upon it, tends frame consisting ofa single iron bar, its end to sag or. warp, and 'thus to obstruct the free portions joined in horizontal alignment'and passage of the lift truck beneath it. bent downwardly tofo'rm legs, and its middle The object of my invention is to obviate portion horizontally returned upon the end 5 this disadvantage, by providing a platform portions to form a side rail; and a top-contop which will resist this tendency; and to sisting of a plurality of closely contiguous this end my invention consists in .a portable metallic-tubes extending between and secured platform comprising a pair of spaced 'leg- 'upon the side rails of said pair of frames. frames and a top consisting of a plurality of In testimony whereof I have signed my 70 metallic hollow members carried by said name to this specification. frames. r EDWARD H. POLK.v
In the accompanying drawings, to which v I reference is hereby made, I have 'shown'my improved platform in its" preferred form 75 though it will be understood that changes 1 may he made without departing from the spirit of the invention as defined in the'claim hereunto appended. In the drawings Figure 1 is a top plan view of myport'able platform.
Figure 2 is a side View of the same. The leg frames 1 are made of wrought iron bars, a single bar for each frame, the ends meeting and welded at l, thence extending oppositely and bent to form the legs 1*, and finally returned upon itself to form the side rails 1, as shown in Figure 2. p 4 Upon these frame rails 1 and welded therep to at 2= are metallic hollow members 2, in sufficient number and closely disposed to form the platform-top adapted to support the objects placed upon it. These members 2 are,
45 in their best form, tubes open at each end, for I I v p the free circulation of air. In practice I use scrap boiler fines for the tubes, though this is not essential.
Such a platform top as is provided by the 59 tubes 2does not sag or warp, but preserves a v
