I Thisfinvention relates to "apparatus for handling and transferring materials such, for example, as sheets or slabs. of builders boards and the like. Among other objects, the invention aims toprovide an improved apparatus of this character which will efiiciently and rapidly handlethematerials for which it is designed with a minimum of manual labor and attention. I

The nature of theinvention maybe readily understood by reference to one illustrative apparatus embodying the invention and shown in the accompanying drawings, 111 which Fig. ratus; I

Fig. 2 is a side elevation of one end of the apparatus; and

Fig. 3 is an end elevation of the end of-the apparatus shown in Fig. 2. u

The illustrative apparatus is arranged, in this instance, for the distribution and han- 1 is a perspective view of the appadling of materials, builders boards, for exl largement 21 111 which longitudinally moving screw 22 is threaded to which, at one-end,

ample, to drying rooms, or to other apparatus for future treatment. Builders boards are usually prepared [continuous web by Well known machines adapted for that purpose. The board thus formed then usually requires treatment,

drying, for example, to-renroveexcess molsture, and for this purpose 1t 18 usually cut into sheets or slabs ofvariouslengths for convenience in handling. These boards in the form of sheets or slabs are large and cumbersome and diflicult to handle and to turn and in many cases very heavy, such, for example, as

boards formed of a cement and asbestoscomposition which in some mstances are approxithe forming machine;

Fromthetormingmachine the sheets or slabs are placed in the lifting and handling apparatus supported from an overhead moving crane, the lifting and handling apparatus s ias desired. Y I
