' To @ZZ whom, it may concern.-

Be it known that I,I WILLIAM F. HUNT, a citizen of the United States, residing at New York, (West New Brightom) in the county of Richmond and State of New York, have invented an Improvement in Conveyers for Ooal, Ore, and other Materials, of which the following is a specification.

Conveyer-buckets have been connected up 1o in endless series, there being a chain at each side or else a rope or other device with suitable connections upon which the gravitybuckets" are pivoted, and these buckets have been dumped at the desired place and sometimes have been employed for delivering coal at one place to a furnace and taking up the ashes and discharging them at another place. In order to allow these buckets to hang freely by gravity and turn upon their Apivots as the zo direction of the conveyer may change, it has been necessary to allowa small space between one bucket and thenext, and where the material has been delivered from a spout or chute such material has passed between one bucket z5 and the next to a greateror less extent, and

lips have been provided upon the edges of the buckets to overlap one another,.and these lips generally being rigid have required to be changed in the direction of the lap according 3o to the direction of motion of the conveyer in relation to the lap of the lips.

The present invention relates to movable lips hinged upon the buckets approximately in line with the inner edges in such a Inanner that each lip is free to rise at the outer edge by contact with the lip of the adjacent bucket sufficiently for the bucket to clear the lip of the adjacent bucket, and means are provided to limit the motion of the lip as it 4o rises and also asit falls after the adjacent bucket passes out of contact with it and also for returning the lips to a normal position.

In the drawings, Figure l is a longitudinal section illustrating the general character of 4 5 the present invention. Fig. 2 is a similar section illustrating the present invention in one of the different forms in which it may be used, and Fig. 3 is a plan view showing the corner of one of the buckets fitted with a hanging 5o weight to return the lip to its normal position.

The buckets A are formed of any desired size or shape and provided with pivots at 2, upon which the buckets hang by gravity from the chains or connecting-ropes B, which pass one at each side of the buckets, so as to connectthem up in endless series, and the chains are provided with rollers or wheels, E running upon stationary tracks, as usual; and I remark that the present invention is available with gravity-buckets that are connected up 6o in endless series between chains or ropes and adapted to receive coal, ore, ashes, or ,other material at one place and deliver the same at another place. The lips C instead of being rigid are pivoted at adjacent to the edges of the buckets and approximately in line with the inner edges of said lips, and they are supported at a slightly-inclinedposition,or nearly horizontal, in any suitable manner, and one lip laps slight-ly upon the other, so that any 7o material that might otherwise fall between one bucket and the next is diverted by the lips into one or the other of the adjacent buckets and cannot fall between such buckets.

I find it advantageous to pivot the lips closely adjacent to but Within the edges G of the buckets, so that such edges may form stops to limit the downward movements of the lips.

I have represented in Fig. l lips C, that are 8o substantially similar upon the opposite edges of the'buckets, and in this figure is illustrated theV fact that one lip 'laps upon the other slightly, so as eectually to bridge over or close theaperture or space between one bucket and the next.

In Fig. 1 I have shown a spring l2 applied to each lip C, and said springs are each connected at one end to an arm on the pivot of the lips and at their other ends to the buck- 9o ets, and said springs prevent the lips being lifted too far and oblige them to return to a normal position.

If desired, a stationary lip 8 can be employed at one side of one bucket and a pivoted lip at the adjacent side of the adjoining bucket, as illustrated at C', Fig. 2. In this instance the pivoted lip is shown as above the stationary lip and bridgingthe space between the buckets, and it is adapted to move either roo -in one direction orthe other by the contact with its outer edge of the rigid lip 8, and the vrigid lip 8v may be arranged to always approach the pivoted lip from below. The pivoted lip C is, however, shown as adapted to swing in both directions and be returned to a normal position, preferably slightly inclined upward, and for thisvpurpose any suitable 4 nections for uniting thebuckets in endless` series, the combination with the buckets, of`

mechanism may be employed, `preferably a swinging Weight l on one end of the pivot A5, that will return the lip to its normalv position, but will allow such lip to yield either one way or the other way, according'to the direction p of vapproach of theadjoining bucket or the lip thereof. With this lip C a stop 7 may be so -located as to limit the swing of the pivoted lip in such amanner that the weight 10 will exert su tlicient force to return the pivoted lip to a normal position.

I claim as myv inventionl. In a conveyer having buckets and conlips, pivots for some ofthe lips approximately in line with the inner edges of saidlipsv for connecting said lips near theedgesof 'the buckets, and means for controlling the movements of said lips on their pivots andreturn ing them to anormal position, substantially as specified. y v

2. In a conveyer having buckets and connections for uniting the buckets in Y.endless series, the combination with the buckets, of lips, pivots therefor approximately in line with .the inner edges of the lips for connect- Ling said lips near the edges of Ithe buckets,

and means for returning the lips to their normal positions after they have been swung on their pivots, substantially as specified.

v3. vIn aconveyer, the combination with the pivoted buckets and the connections uniting the'same inan endless series, of lips bridging the intervening spaces between the buckets, pivots therefor approximately inline with the linner edges ofr such lips for connecting said Y lips near the edgesl of the buckets, and means for automatically retaining said lips in a normal position and for returning them to the normal position after they have been swung von their pivots, substantially as specified.
