Theinvention primarily has for its object to provide novel means for separating and covering certain of various materials such as transporting of a batch ofmaterials in each" such divided compartment, each batch comprising several individual materials in the proportions suitable for an ultimate mix,

for example, of gra'vel,sandandcementg Because of the usual damp nature of the sand and the well known characteristics of p the cement it must of necessity be separated from the sand to retain it in a dry state. Furthermore, it is impractical to transport cement in bulk without a covering to prevent this finely powdered cmaterial; being 2 taken up into the air, especiallyon, windy of transporting cement is forbidden by -regulations.

Therefore in its more detailed nature theinvention resides in the provision in a trans- 3 and means to cover the material separated by i the sheet.

The invention further comprehends a nov-v el overlapped relation of the edges otthe 4 A separating sheet and the covering means which acts in conjunction with the restraining influence of adJacent body wall portions to effect apressure sealing jof the separatedmaterial.

45? Other objects will in part-be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid obJects and ends, the invention still further resides in the novel details of construction, combination and. arrangement of parts," allot gravel, sand and cement being transported edges. v

In the drawings I have shown s'o-muchj of a truck and its dump body as is necessary to illustrategthe application ofthe invention. The invention ismountable on any conven tional form'of such truck and since the body 9 elevating mechanism forms-no part offthe invention it is not shown.

The truck chassis 1 is supported on wheels 2 in the .usual manner and the customary 95 connected piv-otally asat 5upon the chassis beams 1 in the customary'manner and support the body 6 which is equipped as usualwith the rear dump gate 7 swingablyconnected to thebody at 8. f

Batch divider plates or walls 9 are positioned at spaced intervals across the body to divide it into a plurality of batch receiving compartments and the said members 9 are swingably mounted on the body side walls as at 10. Thesemembers 9 normally seat in and are held to position by floor seats 11 and when it is desired to dump a batch, the body 6 first having been raised on its pivot 5, it is only necessary to manipulate the respective handle or'crank 12 to cause the eccentric hub- 13 in whichthe pivot cross shaft is secured to engage the top face of the body side and elevate the member 9 out of the seat 11 to enable it to swing on the said shaft 10.

The'parts thus far described are all conventional and their detailed construction and manner of operation is well understood to workers in the art. Y The invention residesin combining with these parts the covering and separating sheets which I am about to describe.

Associated with each batch compartment is a plurality of separating and covering sheets, preferably of waterproof canvas. In the drawings I have shown two, one indicated 14 to separate the cement from the layer of sand, andanother 15 to cover over the layer of cement. f

The sheets are larger than the horizontal cross sectional area of the respective compartments to enable themto be lapped down into the compartments .to their respective places and to assure thorough covering and separation of the cement layer, and the sa1d sheets aresecured along one edge as at 1.7

to the respective wall 9 or the solid end wall porarily secure the otherwise free edges of the sheets or flaps to completely encase the cement in envelope fashion. One convenient way of accomplishing this is to provide the three otherwise free edges of the associated sheets with the well known Zipper fasteners diagrammatically indicated at 18 in Fig: ure4. In this manner the sheet edges may be joined about the cement while in transit to completely encase'it as a waterproof envelope, and the Zipper quickly releasedjust before dumping to free the sheet edges so that they will not interfere with the dumping of the respective batches.

. *If'desired the separator sheet alone may be connected to the dump body partition wall as indicated in Figures 5, 7 and 10. In these figures the separator sheet is designated 19 and is connected by straps 20 to the body partition wall 21. The cement covering means is in the nature of a free cover sheet 22 having its edges tucked into frictional overlapping engagement .with those of the separator sheet in proximity to the adjacent dump body walls as indicated at 23 so that the pressure of the encased cement will force them against said walls and into intimate sealing contact.

VVhen the separator and covering sheet edges are arranged in engagement as indicated in Figures 1, 2 and 6 said edges may be secured, if desired, by fastening devices as indicated at 24 in Figure 6. Any suitable form of fastener maybe employed but I prefer to use fasteners capable of holding the edges together during transit but WlllCll' are capable of automatic separation when subjected' to the strainof the weight of the pement when the body is dumped. In order to accomplish this all of the fasteners, or only those toward the dump end of thetruck, may be of the automaticallyreleasable type as desired. In order to furtherfacilitate this automatic dumping feature the separator sheet may be slit and overlapped as at 25 to provide a free discharge flap.

, InFigure. 8 of the drawings I have shown a modified form of the invention in which a single sheet 26 is employedwhich' forms the separator sheet and is folded upon itself to spaced above the separator sheet but still co operating in, the materialdesired separation.

and covering function.

It will be readily understood that when the separator and cover sheets are edgeengaged as shown in Figures 1, 2, 6, 7, 8 and 10, the

material separating and covering function will be performed in the desired manner and yet, when the truck body is dumped, the separated material is free to force its way out between the sheets without the necessity of an attendant first releasing any securing means,

If desired, the connecting straps 20 may be secured to the horizontal portion only of the separator sheet 19 as indicated at 31 in Figure 11. This arrangement makes it possible to tuck the cover sheet 22 into edge-to-edge engagement with and outside of all of the upturned edges of the separator sheet. In this manner the overlying edges of the cover sheet I act as a complete water shed for protecting This application is a continuation in part of my copending application of like title filed by me on May 7 ,1929, Serial Number 361,053;

From the foregoing description, taken in connection with theaccompanying'drawings, it is thought that the novel details of construction, the manner of use and the advantages of theinvention will be readily apparent to those skilled in the art to whichit rement; of a flexible separator sheet attached at oneedge tothe front wall and being of an area sufficient to separate upper andlower layers of material and'adapted when the truck is dumped to permit free egress of the layers of material while remaining attached to said front wall, and a cover sheet covering over the upper layer of material and having frictional engagement with the edges of the separator-sheet .to cooperate therewith in completely encasing said upper layer of material.
