Fig; 3, a top plan view, a portion of the buckets being bro the track-clearer; Fig. 4:, a perspective view of one of the bucket members; Fig. 5, a detail sectional view on the line 5 5 of Fig. 1; and

Fig. 6 a perspective view of a'second bucket member.

The object of the present invention is to provide a simple and efficient endless carrier, designed more particularly for use'in transporting coal 01'. other minerals and the The buckets for containin the material are mounted upon endless c ains or belts, which ass about sprocket-wheels or drums located atfthe opposite ends of the run and at intermzdiate points, if so desired, the

buckets b ing of peculiar construction, as

will be hereinafter set forth in detail.

Referring to the drawings, A denotes one of the driving-shafts, adjacent to each end of which is mounted a block or casting B, se-

cured to the shaft in any suitable manner, so as to rotate therewith. The block or casting is substantially rectangular in cross-section and is provided upon each side with outwardly-projecting lugs (J, the adjacent faces of which are paralle while the outer faces are inclined outwardly, so as to form a substantially dovetailed member. Mounted upon each face "of the block B is a sprocket .member 1), said member being rovided with slots or ways of substantially t e same form as the lugs (J and adapted to receive the same, said slots or ways being made slightly larger than the lugs, so as to provide for the reception of wedges or gibs E, which are en away to show the chain and driven in between lugs C and the member D. Said member is provided with a pair of outwardly-extending teeth F F, which pass between the ends of the paired links G and embrace the single links H of the chain. The a face of the member between said teeth or lugs 1s inchned outwardly in each direction from the center, as denoted at F*. The conjoining portions of the members D areprovided with inclined faces F such faces and the faces F reventing the accumulation of material on t e wheel or drum. Thepivotal connection between the link H and the paired links G is made by a rod 1, which passes through the links and extends outwardly beyond the same to provide a su port or axle for a roller or wheel J. Said w eels are adapted to rest and move upon rails or tracks K, and thus hold the chain out of contact with the tracks and roperly position the paired links with "re erence to the sprocket-teeth F F of the driving wheels or drums.

A clearer (best shown in Figs. land 3 is secured to the chain and overlies the track, serving to remove therefrom any coal or other material which Ina overshoot the buckets as thesame are filled or come upon the tracks in any other manner. The clearer in the form illustrated com rises a block L, the forward narrow end of w 'ch is fulcrumed upon a pin M, secured to one of the links G. The rear end of the clearer is of a height equal to that of the diameter of the wheels J, and both edges thereof are provided with beveled faces N, inclined inwardly or away from the supportingmember upon which the track is mounted, so as to deflect any material from the track into the tunnel or other space through which the endless carrier travels.

In order to prevent the clearer from dropping down upon the sprocket-wheel or becoming entangled with any other portion of the mechanism, 1 provide a pivotpin O, which connects theadj acent ends of the paired links G and link H (other than where they are connected by the cross-rods) and projects. 7

through said clearer.

The buckets are secured directl r to the 4, it will be seen that it comprises a cross plate or floor-piece P, having one sideedge Q curved downwardly and provided with a notch R adjacent to each end. Said notches when the bucket member is secured to the paired links G by screws or bolts which pass through openings S, formed in line with said links at each end of the floors iece P, will straddle the single links H, as 0 early shown in Fig. 3. Extending upwardly from each of the floor-pieces P are wings or end pieces T, which are provided adjacent to the floor member with beveled faces U, the purpose of which will hereinafter appear.

A cross wall or partition V extends u wardly from the floor P to one side of t e middle'thereof, said partition being rigidly secured to the end walls. or wings T. The upper portion of said wall V is preferably purved or turned over to a slight extent.

The other member forming a portion of the bucket is illustrated in Fig. 6. Said member comprises a bottom or floor'W, provided with one curved edge X, in which are formed suitable notches Y and Z, that permit said curved ortionto fit over and around the paired inks G of the endless chain. The member is also provided with upstanding end walls or wings A','which are undercut, as are the wings orend pieces T of the other member, the lower undercut portion being beveled, as shown at B. Openings C are formed in the floor W, and bolts or screws passing therethrough secure the member to the links H. The floor W is made slightly longer than the floorP, so that when the parts are assembled the wings or end walls A pass outside of the wings or walls T. (See Figs. 2 and 3.) The parts are so proportioned that when the chain or conveyer is assing along the tracks the walls or wings over lap, as best indicated, in dotted lines in Fig. 1, so as to form a series of buckets, which are defined by the vertical walls V, the end walls or wings T and A, and the floors P and W. By having the end walls undercut and beveled as shown, the lodgment of anymaterial between the ends is prevented asthey close after passing around the sprocket-wheel or drum or as they shift their position inpassing up through an inclined or curved conduit or trunk, as the beveled portions will tend to force the material from between the parts into the buckets or to break up the material so as to prevent injury to the structure.

It is manifest that in so far as the construction of the driving-drum is concerned thismay be materiall modified without departing from the spirit of the present invention, the essential feature of which resides in the particular construction and formation of the conveyer-buckets. By having the upper edge of the wall V provided with an overpoint.

the point of discharge and asses about the drum or sprocket-wheel ocated at such The curved overhanging portions of the floors prevent any large openings being formed therein as they pass around the sprockets or driving-drums, (see Fig. 1,) the center of the curve of such ortions being coincident with the center-o1 the pivotal connections of the chain sections or links.

It is apparent that in so far as the particular construction of the buckets is concerned the same may be employed with an endless In such case, however,'the rounded portion of the floors would have to be omitted.

Having thus described my invention, what I claim is 1. In combination with an endless chain or belt, a series of buckets mounted thereon, each bucket comprisinga series of sections secured to the chain or belt, said sections having overl-a ping end walls provided with undercut beve ed portions.

track; rolls for supporting said chain upon.

thereb a supporting-track; rolls mounted upon t e chain and resting upon the track; and a clearer secured to the chain and resting upon the track, said clearer being provided with an inclined deflecting-face, substantially as described.

An endless conveyer comprising a chain; a series of buckets mounted thereon; a series of rolls for supporting said chain; tracks located in the line of the upper and lower stretches of said chain; and a clearer secured to the chain, said clearer being provided with inclined faces at the upper and lower sides thereof, whereby it will serve to remove extraneous material from both the upper and lower tracks.

the outer edge of the body at each side of the teeth being beveled. or inclined so as to prevent accumulation of any matter thereon.

11. In combination with a driving-shaft, a block or casting secured thereto, said block being polygonal in cross-section and provided with a pairof undercut or beveled faces; lugs extending outwardly from each face thereof; a toothed member arrangedto be secured upon each face of the block, each of said members being provided on its under surface with bevel-faced recesses adapted to receive the corresponding lugs; and keys or wedges for securing the lugs in .the recesses.
