COAL-POCKET.

SPECIFICATION forming part of Letters Patent No. 622,018, dated March 28, 1899.

Application'filed January 28,

To all whom, t may concern:

Be it known that 1, DIGHTON A. ROBINSON, of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Coal- Pockets, of which the following is a specification.

This invention relates to improvements in pockets designed especially for handling coal, though applicable for handling other material, such as ore or any kind of grain; and this invention is designed especially to cover certain improvements ou the coal-pocket shown and described in the application of John Simpson, Serial No. 652,417, led September 21, 1897.

In the drawings, Figure 1 is a side elevation of a coal-pocket embodying my invention, the pocket being represented in full lines asin its drawn-back or retracted position and its forward position being partially indicated by dotted lines. Fig. 2 is a side elevation, partially broken away, showing thel hopper in its forward positionand showing the-eX- tension turned down and the dooropen. Fig. 3 is a perspective view of the 'combined lock and brake. l

In the drawings, 2 represents the body of the pocket, provided with suitable wheels 3 and 5 and supported upon suitable tracks, (indicated in the drawings by the dotted lines-7 and 9.) The manner of supporting the pocket and its mode of operation and general construction is the same as that of the pocket shown and described in said application of John Simpson.

For the purpose of conducting the coal to any desired distance from the end of the pocket and at the same time 'forming a reliable andV convenient means for securing the door of the pocket vI provide at the forward end of the pocket a trough-shaped apron or eX- tension 10, pivotally supported on the pocket by means of a suitable pivot 11, one preferably arranged at each side of the pocket. This extension is adapted to be turned down into the position shown in Fig. 2, in which it forms an extension for the bottom of the pocket and conducts the coal from the pocket a distance equal to the length of the extension. Ledges 13 are provided at the inner end of the eX- tension, and these when the extension is 1898. serrano. 888,818. cromati.)

turned down into the position shown in Fig. 2 strike against the ange Mat the front end of the pocket. A sliding bolt 15 is provided upon the outer surface of the extension, and when the extension is turned np into the position shown in Fig. 1 this bolt engages a recessed lug 16 upon the front of the door 17, thereby locking the extension and the door and firmly securing the same into position. A cord 1S is connected to the bolt 15, and by means of this cord the fireman or attendant can release the bolt 15 and turn the extension outward from the position shown in Fig. 1 to the position shown in Fig. 2, although when the` pocket has been brought into the position shown in Fig. 2 and the bolt 15 is released the weight of the coal in the pocket will ordinarily automatically turn the extension down into the position shown in Fig. 2.

I also prefer to provide a transverse partition 19, preferablyhinged upon a transverse rod 20, passing through the pocket and provided at its lower end with a flange 21, adapted to rest against the bottom of the pocket when the partition is in an upright position. A rod 22 extends transversely beneath the pocket and is mounted in suitable bearings, in which it is capable of rotating. It is provided with an operating lever or handle 23 and has one or more lugs 24.-, adapted to extend through slots in the bottom of the pocket and to engage the Flange 21 on the lower end of the partition 19. When the parts are in the position shown in Fig. 2, the partition will be locked, and only so much of the coal as is in front of the partition can escape from the pocket. When it is desired to release the coal in the .rear of the partition, the lever or handle 23 may be raised', thereby depressing the lug 24 and bringing it out of contact with the iiange 21. This will release the partition 19, and the coal will then fall by gravity under the partition.

I may useone or more of the partitions, if preferred, and may arrange such partition or partitions at any desired point or points in the pocket.

I also provide means for locking the pocket when it is drawn back or standing in the position indicated by full lines in Fig. 1, and I also provide a brake device by which the pocket maybe stopped or held at any desired IOO point in its travel. A suitable beam or support 25 is arranged at a point near the rear end of the bucket, and suitable bearings 2o' are provided thereon. A shaft 27 is mounted in these bearings, and it is provided at one end with a crank-arm 2S, having thereon a suitable weight 29. A cord 30 is connected to this crank-arm and extends to any convenient point, where it may be used by the liremanor attendant for the purpose of releasing the pocket. The shaft 27 is provided with a ilattened portion 3l, having a transverse hole 32 extending through it, and above this hole is a hook or dog 33. A rod 34 is pivoted to the rear end of the pocket and extends through the opening 32 and is provided at its end with a suitable collar 35. This rod is also provided with a lug or shoulder 36, that is in position to be engaged bythe hook or dog 33 when the pocket is drawn back or stands in the position shown in Fig. l. Vhen this hook is thus in engagement with the proj eetion or shoulder on lthe rod 3l, the pocket is locked in position and cannot move forward until the hook is released from said lug. This is done by raising the crank-arm 2S and turning the shaft 27 a sufficient distance to bring the hook out of Contact with the lug 3G. The pocket will then run forward; but it may be stopped at any point in its travel by releasing the crank-arm 2S, which causes the wall of the opening to grip the surface of the rod 34 with suiiieient force to hold the pocket at any point in its travel. This device may also be used for regulating the speed at which the pocket will move forward.

As a safety device I also prefer to provide a chain 39, connected to the rear end of the hopper and to a suitable beam or support 40, as shown in Fig. l. This chain will act as a stop and prevent the pocket from running too far forward.

It will be understood that the form and mode of construction of the various parts may be modified in many ways without departing from my invention7 and I therefore do not limit myself to the details of construction herein shown and described.

\Vhile the pocket herein shown and dcscribed is especially adapted forhandling coal, and particularly for eoaling locomotives, Ido not limit myself to its use for any particular purpose, as it may obviouslybe used for loading coal or other material into ears or into vessels or any other receptacle.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the movable pocket, of the rod pivotally connected t0 the rear end of said pocket, and the rotatable brake-shaft through which said rod passes, for the purpose set forth.

2. rlhe combination, with the movable pocket, of the rod pivotally connected to the rear end of said pocket, and the pivoted hooi; or dog arranged to engagea lugor projection upon said rod when the pocket is in its retracted position, for the purpose set forth.

The combination, with the movable pocket, of the rod pivotally connected thereto, the transverse rocking shaft, the weighted arm connected therewith, said shaft being provided with an openin g through which said rod passes, for the purpose set forth.

4. The combination, with the movable pocket, provided With the rod pivotally con nected thereto and having a suitable lug or projection 3G thereon, of the laterally-arranged shaft 27 provided with the opening 32, the hook 33, the crank-armvQS, and the weight 29, said rod being arranged to pass through the opening in said shaft and the hook 33 being adapted to engage the lug 3G when the pocket is in its retracted position, for the purpose set forth.

In testimony whereof I have hereunto set my hand this 24th day of January, 1398.

DIGHTON A. ROBINSON.
