LOADING AND UNLOADING APPARATUS.

Specification of. Reissued Letters Patent. Reiggued I)e 28, 1909, Original K6 8539995, dated September 22, 1908, Serial No. 398,172. Application for reissue filed June 4,

To all whom it may concern:

Be it known that I, EDWARD E. BARRETT, a citizen of the United States, residing at La Grange, in the county of Gookand State of Illinois, have invented certain new and I i l loading A paratus, of which the following 5 is a full, c ear, and cxact'specification.

My invention relates to loading and unloading'apparatus.

It is illustrated in the accompanying drawings wherein- Figure 1 is a front elevation, Fig. 2, a

vertical section on the line 2- 2 of Fig. 1,

Fig.3, a vertical section on the same line with the parts shown in elevated position, and Fig. 4 is a detail plan View of a-portion of the hoisting bucket.

Like parts are indicated by the same letter in all the figures.

A illustrates the side and bottom of av frame associated with a coal handling apparatus.

B is a bucket having a bail B and connected with the hoisting" rope B The bucket is adapted to lift successively a series of charges of-coal from a lower storage hopper 0 to an upper receiving hopper not shown. Iaaterally projecting from t e bucket are two angle bars B B 'adapted each at its forward end to restupon a' cross piece A and slotted each at B. On the rear end. of

the bucket is a similar an le bar B adapted also to rest on the cross earn A when the bucket is in its lowest position. ()n the projecting ends of the angle bars B B are mounted guide rollers B B.

The hopper C'is shaped in any desired manner but .is provided with a free opening C through which the material-or coal C may escape. In front of this opening is placed the gate which consists of the sides D D mounted on the shaft D which is suitably supported in bearings on the frame pieces I) 1J The gate is completed by the curyed portion D which serves alternately as a stop for the opening C and as the bottom of the gate bucket and the fiat portion D which serves alternately as the forward part of the bucket and as the chute whereby the bucket gate discharges its load. The sides of the gate bucket are inwardly turned at D 'D to narrow the discharge opening. The hopper C is provided with the forcurved downwardly at C to permit the i curved portion D" of the gate bucket to rotate. The bottom D and the sides D D and 1 the side portions D D of the gate bucket useful Improvements in Loading and Unproject beyond the radius on whichthe curved portion D is struck, so as when in the position shown in Fig. 2 to pro ect into the patl'nwy of the bucket B. The side rails- D I) are associated with the bottom of the gate bucket shown.

On the of'rot'ation of the gate bucket and connected therewith are mounted two grooved segments E E and to each is secured a rope E E Each of these ropes passes upwardly over the idler E which is mounted on the frame which supports the hopper C, thence the rope passes outwardly through the slot B around the idler E at the bottom of the shaft in'whichthe bucket B travels, thence each rope passes upwardly over an idler I and a second idler E above which they are secured together and to the end of the rope E which passes over the idler E and has at its farther extremity a balance weight E The idler E is mounted,

on the standard E On each of the ropes is a'button E in the path of the projecting end of the angle bar B The use and operation of my invention,

are follows: As the parts areshown in Figs. 1 and 2 they are at rest, the bucket gate acting as agate and the hoisting bucket filled ready to be lifted. It .now the hoisting mechanism begins to operate, the hoisting bucket B will rise from its position of.

rest andthe-two rollers B B will engage thcrunderside ofthe bars D D and as the hoisting bucket travels upwardly. the gate bucket will be rotated on its axis until the parts will have assumed the position shown in Fig. 3 and the bucket gate will be filled with coal and the hoisting bucketwiil be traveling upwardly in its shaft. As the 1 gate bucket thus rotates, it raises the weight 1 1 which serves as a counterbalance. As thehoisting bucket descends, the slots B receive the ropes E and in time they engage the buttons E tion of the-hoisting bucket evidently brings it into the position shown in Fig. which, at the same time, brings the gate bucket into the'position shown in Fig. 2 and dischar es its measured contents into the bucket .3.

A: further downward Ino'-- Thus the operation continues and the hoisting bucket B receives its load in measured charges so asto avoid spilling fromove'rloading and, the load is discharged 1n such a way as to bridge the interval between the side of the shaft and the hoisting bucket B and thus-no spill will take place at that P v r I It will be observed that I' place intermediate the fixed hopper or supply device and the definite and established path of the hoisting bucket a combined chute, gate and measuring device; that this device in the,

form shown consists of two 'lates which are said chute member outside of such path when serving as a gate:

in eflecttangential to a circ e about the axis on which the gate is mounted; that the chute lies parallel with and just outside the'pat-h of movement of the bucket when the device is acting as a gate and projects slightly beyond or into such pathwhen this plate is acting as a chute; that the plate, which acts as a gate when the device 1s discharging, is placed circumferentially to the axis of rotation and that the device rotates alternately in opposite directions through less than a circle. The plate D in performing the function of a gate, rises through the coal from below and therefore operates as an undercut gate;
