One object of my invention is to construct I an improved sheet-metal platform made of a series of flanged sections.

Another object of the invention is to construct a sectional platform made up of flangedmetal sections connected together at the edges by channel members, forming buifers for the platform.

A further object is to firmly connect th supportinv le s to the platform.

A still fhrt er object of the invention is to so arrange the supporting legs with respect to each other that an elevating and carrying truck may be readily inserted under the platform from any one of the four sides thereof, to move the platform from place to place, thereby increasing the practical utility and consequently the commercial value of the de- And still another object is to provide a sec tional container which is mounted on the platform.

Referring to the drawings, the platform 1 is made of a series of transverse sections 2,

each section being made of sheet-metal bent into Shape as shown in Fi 4 and having a flat body portion '3, depen ing side members 4, and inturned flanges 5. These sections are assembled side-by-side and produce. the platform clearly shown in Fig. 1. This construction dispenses with the use of any separate transverse girders or other supports for the sections, as the form of each section is of suflicient rigidity to carry the weight for which the platform is intended.

At each longitudinal edge of the'platform' is a U-shaped buifer member 6 of sheet-metal. The lower flange 7 of this buffer member extends under the ends of the transverse sections 2, while the upper flange 8 extends over the ends of the sections as clearly shown. This bufl'er member not'only acts as a buffer for the platform but encloses the ends of the sections.

When desired, the ends of the transverse sections may be bent down slightly as, at 9, so that the upper surface of the flange 8 will be on a line with the upper surface of the said sections; so as to make the platform smooth throughout its entire width.

10 are the legs which support the platform at any height desired, these legs being made .of sheet-metal bent into U-shape as shown,

the portions 11 of the legs being inclined and extending into the corners of one of the sections 2 as shown in Fi 1. The section is reinforced at this point y a U-shaped longitudinal section 12, shown clearly in Fig. 6, having flanges 13. This section 12 extends from one side of a transverse section to the other as indicated and restson the flanges 5 of said section.

The upper end of each le extends into this channel member as shown in Fig. 2 and rests against the body portion of this U-shaped member and near the corner of the transverse member 2, and is welded to the members at m and to the flanges 5 at 2,. Fig. 4, while the longitudinal section 12 may be welded at y to the underside of one of the transverse sections 2. 7

In some instances the lon itudinal member 12 ma be dispensed wit and the portions 11 o the legs may be welded at w and at z to the transverse sections as shown in Fig. 8. i

In heavy trucks it is desirable to reinforce the longitudinal edges of each transverse sec-. tion and this is accomplished by making the edges and flanges of double sectlons as shown in ig. 7, the metal bcingbent upon itself as shown in said figure.

When it is desired to use the platform for supporting goods of such a nature that they must be confined on the platform, then a sectional container is used, such as is shown in Figs. 9 and 10. The container 14 is made of sheet-metal and bentlas shown in Fig. 10 and secured together by a lap joint as at 15. The container may be made in one or more sections as at 14-140-446, Fig.- 9, and each section has a lower flange 16 with an extended lip 17 and an upper flange 18, the flange 18 being such that it will fit within the flange 16 as clearly shown in Fig. 9, while the flange 16 is made in such a manner as to fit over the edge of the platform, the flanges retaining the sections in line one with another and with the platform.

Fig. 11 shows a platform in which the supporting legs 10a at one end are equipped with axles 20 on which are rotatably mounted wheels 21. The legs 106 at the opposite end of the platform are shortened and provided with casters 22, the frames 23.of which are pivoted to the underside of the. legs 10b.

The invention is also adaptable to trucks of the character shown ,in the condin applications of Howard T. Hallowel Seria N 0. 182,373, filed April 9th, 1927 and Serial No. 182,374, filed' April 9th, 1927.

2. The combination in a platform, of a series of transverse sections, each section having side walls terminating in inturned lower flanges; short independent U-shaped longitudinal members extendin across certain of the transverse sections, t e ends of'these longitudinal U-shaped members extending into the recess between the bodyof the section and its inturned flanges and leg sections extending into the longitudinal members and welded thereto.
