Each of the eonveyrr element eomprises a plate 'lbi) having one side edge laterally bent to form a retaining wall lit) and ll2l.\ in; secniaid to lie; olher edge a. knife plate .111 extending; past the plate and toothed at its outer edge to bite into the aggregate when operntiiugin ronjunvtion with the latoral ronveyer member- Taking hp now the aperilic monnling of the conveyor proper will; respect to the hbl'lltfllll'KS hrrelnlore tlrmlllflwh a verlieal idle conveyor sprorhel H2 is mounted at lhe outer end of lilo main eoni'eyer member and the main loop of the ronveyer chain is trained aboul [his wheel. and about the wheel (35. The lower is lrainvd about flu: sproeket wheel 94 and from thence about the wheels 92 and from the] me about ntreivh of (he eomever chain the wheel 93. Thus between the rear end of the main conveyer member and the lateral conveyer, the conveyer elements of the return stretch ride on the internualiate track bed 47 and between the lateral conveyer and the forward end of the main conveyor the elements ride on the conveyer bed 36 and in operation convey matorial thereupon.

The elements are retained in proper rela tion to the bed at the bend of its inwardly directed portion by a series of idle sprocket wheels 112 disposed. thereover at this point.

In the main loop of the conveyer, the plates 109 are disposed with their scraper edges inwardly with respect to the main con- Voyei frame, and thus on the bed 46 he relaining walls 110 of the plates eAtend for-- wardly and coact with the wall '(7 of the hell to form eoniliiartmenis holding the matrrial to be conveyed. In the lateral loop, the position of the plates with respect to iln: room-yer bed is reversed and thus in ii: arr-sing the rearward .sireteh of the loop iiw toothed fillgt-la of the plates engage the pile of aggregate with a scrapingor digging zutizm, at lhe \aine time conveying the aggregate toward the main conveyor bed so that 'tlu aggregate carried :ltlurss the connecting plate 9b and onto the main conveyer bed.

Assuming that the respective eonveyer members are employed to convey difl'erert kinds of aggregate. .alitll as sand and gravel, it is essential to provide a means whereby rleliniie relaliie pro 'iortions of the different nialeriala may he ronveyed, and it is essen lial tn proriiha means for varying the said proportion to meet different rondiiions of work To awoniplish this variation, the hopper St'tlAOlh, -33 of the body truel; 0on1- prki a main hopper easing 113 which is provided along ll. forward and rear edges niih holdingbars 1H provided in their opposed rdg: w th series of corresponding pairs; of rereswb 115i, rorrespoiulon; recesses being adapted to weloctirely receive one of a plurality of Vertical partition plates 116, time of these plates being provided to pro- (lll'l a maximum dew-re of variations of the hopper .wPtfliUllS defined thereby.

Thus. in operation both of the main eonrow! numbers are simultaneously operated. Upon the smaller hopper being filled, the operator stops the ronvever. by shifting the ohm-h ll thereof and the other eonveyer nniuher "LlilllHHS in actuation until the larg r hopper i; filled at llit'li time both of like hoppers are dumped. and the operati n repeated The operator standing on the platform 53o has ready access boih t0 the Windlass drums which (lHlllOl the movements of the coni'rrer members, and lo the hopper lever 29 whieh is nuiunledon the platform and thus the entire machine may be eonreniently operated by a single person standing in a poeition to observe the discharge or material into the hopper sections. Each of the wind lass drama 7]. and 98 have a plurality of ratchet teeth 11? formed on their huha, which coact with a pawl 118 carried by a bracket 119 mounted on a respective portion of the Windlass drum shaft li -l, to hold the drums against: undesired movement.

In some concreting operations, a single mass of mixed aggregate comprises the ma-- terial to be conveyed, and in this connect ion the aggregate is piled along the roadway in the usual manner and both conveyor mum hers are employed to eimultaneou'eily convey the aggregate. The provision oi: the two conveyor members in this connection com stitutes a distinct advantage inaeinneh as an exceedingly light and mobile structu e is procured having maximum capacity.

Attention is directed to the Preceding narrownees of structure of the main conveyor inenilrers, which permits them to op crate between pileo of aggregatidispo 'el close together.

To position the main conveyor memliere 211: shown in dotted lines in Fig 19, the Wind lass drums 98 are actuated to lift the con veyer frames from the ground, and the frames are then swung manually to the'dcsired position, the wheels at at the outer ends thereof being swiveled. In this movement, the pulleys 72 and 100 which are mounted on the upper pivot shafts 31 serve to guide the respective cables 72 and ill) for proper operation. As the main convey 1 frames rest throughout the greater porti n of their lengths directly on the arounda firm support if; had vfor the frames and they are il'i iui ally held by lheir i'ngagi un ol with the mud against lateral oi plaeemei t ouch as voulil tend to occur liv :uieoik all straii'ie e10 l'lrll in the ul'ious opwai i. vi" the lateral conveyor members.

Although the present machine has been specifically deacribed in connection with col crete mixers. it is apparent that vnriniw lea tures of the device may he used in other conveying operations and it is also apparent that various modifications of structure and operation may be resorted to in adapting the machine for different comlitirms of use Without dcpartimgin any manner from the spirit ol the invention as emhralicd in the appended claims.
