PLATFORM SKID.

Application filed September 5, 1922. Serial No. 586,209.

To all whom it may concern. v

Be it known that I, RICHARD T. GIFFORD, a citizen of the United States, residing at- Springfield, in the county of Hampdefi and State of Massachusetts, have invented new and useful Improvements in Platform Skids, of which the following is a specification.

The present invention relates to transferable load-supporting platforms which are commonly known as platform skids and are used in connection with systems of trucking wherein elevating trucks are employed to transport said platforms and the goods supported thereon.

One object of the invention is to provide a transferable load support of the platform skid type having increased load-carrying capacity and in which the load may be compactly arranged and conveniently and safely handled.

Another object of the invention is to provide a transferable load support of the general character above referred to in which a plurality of loads of material may be supported in closely adjacent but segregated relation.

In accordance with these objects, one feature of the present invention consists in the provision, in'a transferable load support, of a plurality of load-supporting platforms, and means or supporting these platforms one above another in spaced relation for the purpose of separately supporting a plurality of loads.

A further object of the invention is to provide a transferable load support comprising a plurality of load-supporting platforms adapted to be detachably assembled in superposed relation to constitute a sectional or extensible load support the capacity of which may be increased by the assembly of additional sections therewith or reduced by the removal therefrom of one or more of the sections.

A further object is to provide a transferable load support having a plurality of superimposed load-sup orting platforms wherein the several plat orms are each provided with end gates constructed and arranged to supportthe platform above them. I A still further object of the invention is to provide, in a platform skid having removable end gates, devices for supporting said gates which are so constructed and arranged as not to interfere with the transportation of the skid in congested areas and are thus free from liability of beinginjured.

Further objects of the invention will a pear in connection with the following escription of the preferred embodiment thereof illustrated by the accompanying drawings, in which:-

Fig. 1 is a view, in side elevation, of a sectional or extensible load support constructed in accordance With the present invention;

fFig. 2 is an end elevational view there- 0 Fig. 3' is a detail sectional view of a corner portion of one. of the upper load-supporting platforms showing one of the brackets or socket members which receive the platform supporting posts;

Fig. 5 is a top plan view thereof;

Fig. 6 is a perspective view of one of the legs which support the lowermost platform; an

Fig. 7 is a side elevational view of the leg shown in Fig. 6.

Referring to the drawings. the transferable load support therein illustrated comprises a series of rectangular load supportlng platforms 8 which are firmly support ed one above another. Each platform 8 may be constructed of a plurality of transverse load-supporting members, such as the planks indicated at 9 in Fig. 1, or if found more desirable each platform may be formed from a single piece of suitable material. The planks 9 may be arranged in abuttin edge-to-edge relation, or they may be spaced relatively to one another. As shown, the planks 9 rest upon angle-bar tie members 10 which are disposed parallel to eachother and extend len thwise of the platform. The platform pinks 9 are secured to the tie members 10 by means of bolts or rivets 11 Fig. 3) the heads of which are countersun: in said planks, while the shanks of the bolts extend through the horizontal flanges of the tie members 10. Preferably the tie members 10 of the lowermost platform are arranged with their horizontal flanges extending outwardl from their vertical flanges while the tie members of the otherplatforms are arranged with their horizontal flanges extending inwardly from their vertical flanges.

The lowermost of the load-supporting platforms is supported from the floor by means of legs 12 which are located ad acent the four corners of the platform. Each leg 12 is preferably made of a single casting shaped as illustrated in detail in Figs. 6 and 7. As shown, the leg castings comprise upper or sill portions 14 and lower or foot portions 15. The sill portions 14 are formed with upper ledges 16 and depending web plates 17 which are adapted to lie against the horizontal and vertical flanges, respectively, of the angle-bar tie members 10 and are rigidly secured to said flanges by means of suitable bolts or rivets which extend through apertures 18 in said sill portions and ledges. The foot portions 15 are parallel to the ledges 16 and are connected With the sill portions by means of side flanges 20 consisting of upper parallel portions 21 and downwardly converging lower portions 22.

The legs 12, in addition to supporting the lower platform from the floor. are constructed to receive upright posts 24 which rise through suitable apertures in the plat form and serve to support another platform above the lower one. To this end the ledge 16 of each leg is extended, as shown at 25 in Fig. 6, to support a sleeve portion 26 which is adapted to project upwardly through an aperture in the platfrom and to provide a guide and bearing for one of the corner posts 24. The foot 15 is also provided with a recess or socket 27 to receive the lower extremity of said post. Thus it will be seen that by passing the posts 24 through the sleeve-like bearing portions 26 of the feet 12 and by seating the lower extremities of said posts in the sockets 27 the posts will be firmly supported while in use and may be readily removed from the platform when desired. It is important to note that by making the sockets 27 in the feet 15, as above described, the side flanges 20 of the legs 12 are released of all load-supporting strains and the load is supported directly from the floor.

The posts 24 at each end of the platform may be connected by one or more horizontal cross-bars 28 so that the ports and cross-bars together constitute an end gate which functions to prevent the load from falling off from the platform. If desired, the posts 24 may be connected by bars which extend lengthwise of the platform and thus serve, in conjunction with said posts, to provide side gates for the platform.

To increase the load-carrying capacity of the support without enlarging the size of the platform already described one or more additional platforms may be provided which are adapted to be'supcrimposed above the lower platform. As shown, each of these supplementary platforms is provided with four brackets or fixtures 30 which are located adjacent the corners of the platform and are adapted to perform the double function of detachably securing the la'tform which carries them to the posts rising from a lower platform and to support another series of posts which may serve to support an upper platform and which may be connected by cross-bars so as to provide end or side gates for the platform carrying said fixtures.

Each fixture 30, as best shown in Figs. 3. 4 and comprises a sill consisting of an upper ledge 32, which is adapted to lie against the lower face of the horizontal flangcof one of the tie-members 10 of one of the supplemental platforms, and a web portion 33 which depends at right. angles from said ledge 32 and is adapted to lie against the inner face of the vertical flange of said tie member. Extending from the lower edge of the web portion 33, in parallel relation to he ledge 32. is a lower ledge 34. The two ledges and 34 support a cylindrical portion 36 in which is formed two axially alined sockets 37 and 38, the socket 37 opening at the lower side of the fixture and being adapted to receive the upper ends of one of the posts rising from a lower platform while the socket 38 opens at the upper side of said fixture and is adapted to receive and support a post which may in turn be employed to partially support an upper platform. To strengthen and stiffen the whole fixture. a reinforcing web 39 connects the upper and lower ledges 32 and 34 and also connects the socket portion 36 with the web portion 33. The fixtures 30 are rigidly secured to the platform which carries them by means of suitable bolts or rivets 40, one set of bolts extending through the web portion 33 and the vertical flange of the respective tie. member 10, as indicated at 40 in Fig. 3, while another set of bolts extend through the upper ledge 32 and the horizontal flange of said tie member. Preferably certain of the bolts 11 which are employed to secure the platform to the tie member 10 are extended through the ledge 32, as shown in Fig. 3, and thus serve also to secure the fixtures 30 to the platform.

The fixtures 30 are so arranged that when the platform which carries them is placed directly above another platform, the sockets 37 and 38 in each of said fixtures will be substantially in axial alinement with the osts 24 rising from the lower pla ter a. referably the lower sockets 37 in the fittures 30 are rovided with tapering side walls, as clear y shown in Fig. 3, to assist in registering said sockets with the posts of a lower platform and in forcing said sockets The above described construction provides,

in a practical form, a sectional or extensible platform skid type of transferable load support wherein the extensible or supplemental platforms may be readily placed in position or easily and quickly removed when desired. The guide or bearing portions 26 of the legs 12 and also the socketportions 38 of the fixtures 30, being arranged to extend upwardly through the platforms-provide linings or bushings for the reception of the supporting posts whereby the platforms themselves, which are preferably made of wood, are protccted from injury in the use of said posts. The fixtures 30 and the legs 12 are so arranged that they do not project beyond the rectangular outlines of the platforms and thus they are protected from injury and will not interfere with the transporting of the load support. lVhen three or more platforms are employed, the corresponding supporting posts of all platforms above the lowest will be maintained in axial alinement and the weight of the loads on said platforms will be supported independently of the lowest platform and transferred directly to the floor without imposing any strain upon the side members of the legs 12 which support the lowest platform.
