BUCKET CONVEYER.

' SPECIFICATION forming part'of Letters Patent No. 637,716, dated November 21, 1899. 7

Application filed December 31, 1897- Serial No. 664,962. (No model.)

To all whmn it ntoty concern:

Be it known that I, JAMES M. DODGE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bucket Conveyers, of which the following is a specification.

My invention relates to that class of pivoted bucket conveyersin which the buckets are arranged to overlap, so as to prevent the [0 waste of material in charging the buckets.

One object of my invention. is to so construct the mechanism that the buckets will draw away from each other as they pass from a horizontal run to a vertical run or pass around a wheel and relap as they assume the position on a horizontal run.

My invention relates, further, to the construction of the feed-chute and also to the discharging apparatus.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved pivoted bucket conveyer. Fig. 2 is a transverse section on the line 2 2, Fig. 1. Fig. 3 is a side View of the discharging mechanism. Fig. 4

2 5 is a side view of the feed-chute, and Fig. 5 is a plan view of the'.feed-chute.

A are the links of an endless chain pivoted at a, and each link has an arm a, projecting, preferably, at right angles to the link,-and from this projection is suspended the pivoted bucketB at b. This pivoted bucket has a lip 19 at one end, and the buckets are so proportioned in respect to the links that when on either the upper or lower horizontal run the 3 5 lip of one bucket will overlap the opposite end of an adjoining bucket, as illustrated in the drawings, so that when material is fed from the chute D the overlapping lips of the buckets will prevent the material from escaping between the buckets.

The conveyer moves in the direction of the arrow 1 and the buckets are discharged in the direction of the arrow 2, so that the lip on the upper run is at the rear of the bucket, and thus the bucket can be dumped withoutinterfering with the one following.

It will be noticed that as the chain passes around the curve in going from a horizontal to a vertical run the bucket pivoted to the link is drawn away from the adjoining bucket owing to the fact that it is hung to the link at one side of the center line of the link, in the present instance being pivoted to the arm a. By this means the buckets will free themselves automatically without complicated mechanism and will again overlap as soon as they return to the horizontal run from a vertical run.

I have shown in the drawings the feed-chute D pivoted at d to the hopper D, and on the feed-chute are curved plates at, which rest upon the wheels 0 of the conveyer-chain. These wheels are adapted to the rails C O on the horizontal runs, as shown in Fig. 2. By

means of the curved plates on the chute D a rising-and-falling motion is given to the chute, so that the material will be intermittently fed to the several buckets as they pass under the chute.

. In the present instance the buckets are discharged by means of the device shown in detail in Fig. 3, which consists of a carriage E, having wheels e adapted to the rail F. This carriage is guided by rails F, preventing its lifting oif the main rail by the action of the buckets. The carriage has inclined ways e e e c, and on the buckets are projections i i, which come in contact with the inclined ways. The pin 2" first strikes the inclined way e tilting the bucket a portion of the distance, and then the pin a strikes the inclined way e, discharging the entire contents of the bucket. This pin 11 rides upon the surface of the way 6 until it reaches the inclined way e when the bucket commences to assume its normal position. The projection i will then strike the way 6 and the bucket will be guided by it until released therefrom, when it assumes its normal position.

The carriage can be moved along the upper run of the conveyer by means of a rope g, so as to discharge material at any point through the run.

I claim as my invent-ion 1. The combination in a conveyer, of an endless chain made up of a series of links, arms projecting from the links, buckets pivoted to said arms, each bucket having a lip adapted to overlap the edge 01": an adjoining bucket, substantially as described.
