Beit known that I, JAMES H. STEVENS, of East Durham, in the county of Greene and Improved UnloadingAttachmentforWagons; and I do hereby 'declare that the following isa will enable thoseskilled inthe art to makeand. use the same,-reference Vbeing had to .the accompanying drawings, forming part of this specification,i n which- Figure l is a. longitudinal vertical section of Fig. 2, indicating theliix'e of section; Fig. 2, a

Similarletters of reference .indicate corre-- T1i' nvention relates to a' newfnnd im proved 'unloading attachment for wagons.

The object of the invention is to obtain a device for the purpose specified which will admit of being applied to any ordinary wagon-body in use, capableof being constructed at a very moderateexpense, and operated with the greatest facility. A represents a wagonbo'dy, which may he' constructed in the ordinaryway, andtherefore' does not require a minute description.

B is an apron constructed of slats a, attached near their ends and at their center to straps b b b. One end of. this apron' .is connected byv straps c c with a s haft,'G, which is. below the .rear end-of the body A, the bearings of said .shaft being .in blocks'd,"attached`to the under a shaft, D, which .is placed on the' upper part` E, at onerend oi. it. "Tlije shaftGiI- as smoothed wheel, F, ationeend'. 1o;t`.i t',x ih to whicliga't'pinion, G, gears,the latter beingon a shaft, which,

at therear ofthe bottomg'of the wagondiody e and. there@ am@eonediofeeaae roller f .1g ner surface lofte receive the ends of the slats a of the apron B, serving as guides for the same.

. K is a'roller, which is fitted in the sanie blocks d as theshaft C, the roller-K heilighelow vthe roller l, suticient space being between that by turning the shaft C the apron B will be woundgupon the shaft C, and. as this apron forms a fatse bottom the load-whichl rests upon it will be discharged from'the wagon-body A. By turning the shaft D the apron B will he .drawnback into the body.

The'bottom .17* of thebody Alias twoorinore parallel rails',j?7 attachedxlon gitudinall y t'o it for the apron B to rest upon. These rails form a drm 'bearing-for the apron and at-the same time admit ot' the latter working freely overit without causing much friction. The bottom i* is not strictly necessary, as the rails jj may be. attached to cross-pieces von the wagon-body. l The rails ymay be wood or metal.

- lheroller K and straps L L serve as a. support 'for the apronB, preventing the latter from beingdrawn ontof thebodyonunwinding from shaft e by its own weight whenhearly-fully wonndupon shaft'G. The straps L L also serve to con tine the roll of apron within proper limits when wound up'on' shaft C, but -chiefly to keep apron from uncoiling from shaft. By this arrangement it will be seen thatIcan dispense with friction-rollers hitherto-used in devices of this kind for the endless apron to work upon. .1. also `dispense .withfman'y other .parts hitherto used and'which render the device quite .cmplicatedand liable tn get nutnf repair.' improiement possesses the advantage of being capable of being applied to an ordinary wagon-body., and itinaybe-manipu ated .with
