To all whom t may concern."

Be it known that I, NELS P. JoRcENsoN, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented `certain new and useful Improvements in Conveyers, of which the following is a specification.

My invention relates to improvements in conveyers, and the object of my improvement is to furnish means for receiving, transporting and delivering substances, such as barn or stable droppings, from the building where Stich substances are iirst deposited to some place or receptacle adapted to receive them.

This object I have accomplished by 'the mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawings, in which:

vFigure 1 is a side elevation of'my said conveying mechanism, as placed in a suitable position for use. Fig. 2 is an en larged detail cross-Section of thev kstable trough with the included scraping and conveying means, and of the means for actuating said conveying-means. Fig. 3 is a cross-section of one end of said trough, and of the mounts and other parts adjustable therein for supporting the end sprocketwheel of the conveyer-chain. Fig. 4'is a cross-section of the inner part of the foldable trough, and Fig. 5 is a cross-section of justable supporting-means.

the outer part of the outer conveyer-trough, in each case the supporting-meaus for the sprocket-chain idlers being shown. Fig. 6 is an enlarged elevation of one of the sprocket-idlers- Fig. 7 is a side elevation of one of the end sprocket-idlers with its ad- Similar numerals of reference denote corresponding parts throughout the several views.

Referring first to Figs. 1 and 2, the numeral 1 denotes .a concrete trough, which may be made in alined sections secured together if desired, adapted to be placed in a stable abutting upon the stalls in a trench suitably formed to receive it. The trough has depending spaced apart longitudinal parts 42 whose lower ends rest upon the top of the bottom of the trench so as to furnish an inclosed space between them in which the sprocket-chain 15 may travel. One part of this trough may-have a lateral projection 43 provided with a pit adapted to receive a gear-wheel 42. The trough is of a rectangular form inl crosssection, and in 1t scraper-blades 16 of proper dimensions to extend across it to scrape over its bottom are located secured to the inner face of a conveyer-chainl. This chain being seated movably longitudinally through the middle of the trough 1passes about sprocket-idlers 27 and 26, located respectively at what will be called the rear end of the apparatus, and at the forward end of same. The chain has its depending part which travels in the space between the standards 42 of the trough 1, further supported on idler-sprockets 36 and 17, which are respectively supported in bearings in depending brackets 35 and 18 respectively secured to the parts 20 and 21 of the movable trough of the apparatus: If deslred two such chains and an accordant system of supports may be adopted with connections to the scrapersblades 16, but the method shown is simpler and cheaper, while retainin In or er to keep the sprocket-chain 15 in a proper state of tension, I have adopted for that purpose the following-descriloed means. Referring to Figs. 3 and 7, the numeral 46 denotes a metal plate mounted in the trough 1 at its rear end, securely, provided with a bearing for the vertical shaft the Same principles of operation. y

29, and with a slideway 48 for a slide 47, the

wheel and said gears may be turned to adjust the position of said Slide aud of the idler' 27 to maintain the latter under proper tension.

. Any suitable mechanism may be employed to drive the chain 15 forwardly, but I have shown means whichare now to be described. A frame 5 is supportedon the forward'end of said concrete trough 1 and has at its upper end a bearing for a` short shaft 7 a crank 9 being removably connected to said shaft on one side of the frame and a bevel-pinion 3 is rotatably mounted having onits lefthand end a bevel-gear 42 in mesh with said pinion 41. Upon said shaft 3 is secured a relatively large sprocket-wheel 4. which meshes with said sprocket-chain 15. Vhen said crank 9 is rotated in one direction, said intervening mechanism causes a forward movement of said chain 15, carrying the vScrapers 16 forwardly through the trough 1 and-over the upper surface'of the communicating trough parts 20421. The troughparts 20 and 21 are preferably formed of 4 large a number as may be useful.

metal, and the rear end of the part 20 is `hinged on pintles 33 to the uprights on the forward end of the concrete trough 1. The parts 2O and 21 are hinged together by means of a hinge 19. In Fig. 1, the trough parts 20, 21 are showii extended forwardly in operative positions,` but said parts are made foldable to be retracted upon the wall of a building out of the way b v the following means. A cable 23 supports the outer or forward end off the trough' part 21., being secured to an eyebolt 24 above in the building. Another cable 12 has one end fastened to a medial Ipart of the trough 20 fis then passed upwardly over a. pulley in a block 13', thence downwardly about a windi/n, ,drum

1.0 and thence downwardly again and about aV pulley 14 secured to the, base of the building and then secured to the trough 20. The cable 12 is detachably secured to said drum 10 in the following manner. A small circula'r hollow or socket is formed in the middle Cil part of the circumferential surface ofthe drum, and in said socket a circular bend of the cable 12 is placed, and then a screw 39 is passed down into the drum through the hollow ol the cable-bend, its ianged head engaging the bend and securing it to the drum. In this Way, when the drum is turned by means of its removable crank l1 in one direction, the upper part of the cable 12 is wound up while the other or lower part is slackened, and the reverse occurs when the4 drum is reversely rotated. In this way, the trough part 20 may be drawn up against the building, the part 21 folding thereover.

'movable Since the scraper-blades 16 are located to face inwardly from the chain 15, it isnecessary to prov'de suitable sprocket-idlers to permit the b ades to pass them without interfering in transit. This is effected by forming these wheels as shown in Figs. l andI 6, wherein' the webs between the sprocket-teeth lare reduced to but the rudiments 2G, which are so near the axis that the scraper-blades 1G may fall between the teeth without interference.

The driving-sprocket wheel 4 has its teeth modified, as shown best in Fig. 1, by having :their forward edges made straight and radial the rear edges only being curved, which causes the straight edges to pick up the i cham 15 and seize 1t with a secure grip un.

til released.

The trough section-s, whether ot' concrete or metal may be formed 1n ahned parts of as Having described my invention, what I c laim as new, and desire to secure by Letters Patent, is:

-1. 1n a conveyor, a horizontal fixed integral body longitudinally troughed at top and bottom, a movable endless chain passed about said body within both troughs and spaced apart therefrom,y scraper-blades fitting the interior of the upper trough and therethrough longitudinally to scrape its bottom and adapted to return through said lowertr'ough, said blades being secured ixedly to links of said chain on their inner faces.

2'. In a conveyer, a fixed body provided on its upper face with upstanding fixed integral spaced apart walls to provide an open-ended longitudinal trough therebetween, and having integral depending spaced apart walls to provide a down wardly-opening openlended trough on its under side opposite the upper most trough, an endless movable chain passed about said boetvwithin said troughs and spaced apart'thcrefrom medially, -and scraper-blades secured to inner faces of links ci' said chain and depending toward the bottom of the upper trough and adapted to fit the trough and scrape over its bottom and to return within thelower trough.
