Jr., a citizen ofthe United States,`residingat Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Conveying Apparatus, of which the following is `a specification, reference being had therein to the accompa nying drawings.

In this apparatus is comprised a platform provided with tracks upon which the loaded cars are adapted to berun and containing a tilting mechanism by which the contents of' the cars may be discharged, a receiving-chute 4o or loading-hopper, into which the contents of the cars are dumped and from which the material is conducted to another trough or chute leading to receiving-hoppers or pockets or otherreceptacles, the conductor-chute being provided with endless chains or cables suitably supported and having buckets or plates at intervals and traveling within the conductor-chute in lthe same direction as the flowing material, but at a slower speed than 5 a the natural flow of the material, whereby the `as it can be disposed of to advantage.

material is retarded and fed to the receptacles at the discharge end ot` the conductorchute in a uniform stream and only so fast By this means the material may be conducted `down a chute thatis much steeper than could hejotherwise employed, as by the use ot the retarding mechanism the material may be fed down the chute at any required speed, the speed being regulated by the nature of the material or the conditions or incline of the slope down which it is required to be carried.

The apparatus is more particularly applicable to the conducting ot' coal and similar products down steep inclines, to accomplish which it has heretofore been necessaryto erectexpensive and cumbersome systems of inclined railways and similar structures. Vith my device, however, the troughs, with the chains or cables and their retarding buckets or plates, may be erected at comparatively small expense aud without regard to the degree of inclination at which they are run and can be easily adapted to the varying nature and incline of the ground or the topography of the locality where it is to be erected. The structure comprises generally a platform, which is represented as a whole at l, upon which the loaded cars 2 are run; atilting mechanism 3, by which the loaded cars may be tilted to discharge their loads; a receiving-chute or loading-hopper f1, into which the contents of the cars are dumped; a conducting-chnte 5, down which the material will iiow from the loading-chute; a receptacle 6 at the discharge end of the conductingchute, and the chains or cables 7, having the retarding buckets or plates 8 and traveling slowly down the conductor-chute.

Instead of the tilting platform the loadingchute 4 may lead directly from the storage bins or pockets, and instead ofthe receptacle 6 the material may be arranged to discharge directly into cars or boats or other receptacles or to picking or screening tables, as may be required.

In Figs. 1, 3, and 4. the tilting mechanism is shown, which is of the ordinary construction, and consists in side rails 36 and 37, conforming to and registering with the railroadrails 33, preferably inclined and leading from the mine or other source of the supply of the material. These side rails 36 and 37 are suitably united and are supported near their forward ends by curved bars or tilting rockers and hinged to connecting-'rails 11 12, which are in turn hinged by their other ends to the rails 13 14, by which the cars are removed after being unloaded. The side rails 36 37 have the removable curved stops 15 16, by which cars are supported while being dumped.

The loading hopper or chute 4 is constructed with diverging sides 39 and with a central opening 17, n'otected by a shield 18, the opening aording means for mounting chainsheaves 19, over which the chains 7 are conducted, and the shield 18 dividing the material and conducting it around the opening.

Leading downward from the converging lower end of the loading-chute 4 is the inclined open conductor-chute 5, formed, preferably, of metal, with a flat bottom and outwardly-inclined sides, as shown in Fig. 5, and supportedlin a framework 20,resting u pon the surface of the ground or upon a suitable supporting-framework, as may be required by the nature of the ground over which the trough leads. point where the material is to be discharged, either into storage-bins 6, as in Figs. 13 and 14, or to picking and screening tables, or otherwise, as may he required. The framework 2O is formed with stringers 2l, whose upper surfaces are even with the upper edges of the sides of the conductor-trough 5, and afford supports for the downwardly-moving sides of the endless chains 7,as shown, to keep them in parallel relations to the bottom of the conductor-trough, while the upper or returning sections of the chains are supported by similar stringers 22. parted to the chains 7 in any suitable manner, as by a separate engine 23, as indicated in Fig. 13. The transverse plates or buckets conform in outline to the conductor-trough 5 and, as before stated, travel slowl)T down the trough. These plates 8 are each supported in positions at right angles to the trough and are strengthened by transverse anglebars on their rear sides. The incline of the conductor-chute may be of any required degree and much steeper than the material could with safety be permitted to flow down it; but by employing this'retarding device the material can be slowly conducted down even a very steep incline with perfect safety. The side guide-frames 2l 22 thus support the chains 7 at all times in parallel relations to the bottom of the trough, and thus prevent the lower edges ofthe buckets 8 from dragging on the bottom of the trough on the down side and also prevent the up side from sagging downwardand interfering with the oppositelymoving down side.

26 represents guard-stringere arranged' above the lower sides of the chains 7 and parallel to the stringers 21 to serve as guards to The trough 5 will end at thev Motion will be imthe down side of the chains to prevent them from being lifted when the strains are brought to bear upon the chains, and thus insure the down series of buckets acting at all times in proper relations to the trough 5.

The conductor-chute may be covered and protected, as by a roof 27, as shown in Figs. 1 and 5, if required.

In Figs.9 to 15 some modifications are shown in the structure. In this structure the endless cable 7, carrying the retarding-ights, is mounted to travel over the vertical sheaves 28 29 at the ends. In this modification the retarding-buckets are in the form of circular disks or flights 30, and the trough 50 is in U shape in cross-section, as shown in Fig. 10, the return side of the chain and its flights 30 being borne by the supporting-stringers 3l,

as shown in Figs. 10, 13, and 14. To prevent the material from clogging the retardingflights 30,a retarding-wheel 32 is arranged between the upperend of the conductor-chute and the lower end of the loading-chute 4, the wheel 32 consisting of a number of blades 33, and thereby forming a series'of pockets between the blades adapted to receive the material as it flows down the loading-chute and deliver it intermittently to the conductorchute between the flights 30, so that at no time will large masses of the material be deposited in the conductor-chutewhere the downwardlymoving return flights 30 can strike it. The wheel 32 thus delivers the material-in comparatively small quantities at regular intervals and so timed as to deliver these masses only between each pair of the flights 30 and retain the next mass until the next flight has passed the point of delivery to the chute. The upper cable-sheave 28 is protected Within the upper end of the chute by a guard-plate 34, while the sides of the chute opposite this guard diverge, whereby two passages are formed for the material one on each side of the cablesheave, with a combined area equal to the total area of the body ofthe chute. The material is thus conducted past the cable-sheave and delivered to the chute on each side below the cablesheave and without danger of clogging the cable or flights, as before stated. Motion is imparted to the bucket-wheel 32 by a chain 40 and gearing 35, so that it will revolve slowly, and thus serve to hold back the material and deliver it only at intervals corresponding to the spaces between the flights 3@ on the cable 7. In Fig. 12 the mechanism of the retarding-wheel 32 is shown more clearly in perspective.

The loading-chute 4, it will be noted, is set at a steeper incline than the conductor-chute, whereby a positive feeding of the material is insured at the commencement of the operation to prevent the possibility of any clogging taking place in the loading-chute.
