` To all whom it may concern? Be it known that I, FRANK J; Soi-mAEnER, Jr., a citizen of the United States of America, and resident of Glenellyn, Dupage county, Illinois, have inventada' certain new and useful Improvement in Hoisting Apparatus, of which the following is a specifica and travels u tion.

My invention relates to hoisting apparatus in general, but more particularly tothat involv-ing'a bucket which receives the load and down, and especially to apparatus or handling coal.

Generally Stated, the object of my invention is to provide a novel and improved hoisting apparatus of Ithe foregoing general character. y

A special object is toprovide an improved construction and arrangement whereby the coal may bedischarged directlyfrom the .bin into' the bucket, without the use of intermediate conveying devices, and whereby the gate for the discharge opening of the bin is automatically controlled by themovements of the bucket.

It is also an object to provide certain details and novel features of construction tending to increase the general eiciency and scrviceability of a coal bin and hoisting apparatus therefor of this particular ICharacter. f

To these and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings,

Figure 1 is a side elevation of a hoisting apparatus embodying the principles of myl lnvention, showing the concrete coal bin therefor in vertical section, and showing the bucketiin position to open the gate and re,- ceive the discharge of coal from the bin;

Fig. 2 is an enlarged detail sectional view ofthe valve employed for automatically controlling the movements of the Vdischarge gate; v A i Fig. 3 is a-view similar to Fig. 1, but

showing the said bucket and gate in vertical section, and in position to enable the bucket to receive a load of coal from the discharge opening of the` bin; .A F ig. 4 is a horizontal section on line 4 4;

in Fig. 1. l

' As thus illustrated, my invention com# a concrete coal bin A, of any suitable,

as y xmor approved construction. and proY videdatthe lower edgeof its inclined bot- ".tom a with Ialateral discharge opening a1,

through which the coa-l is allowed to escape. Normally this discharge opening is closed by the pivoted gate B, which latter is mounted to turn about. an axis Z2 of any suitable 'character' supported by the`parallel and rhorizontally disposed I-bean'is a2, between which the said gate swings up and down, and which are supported by the concrete walls of the pit a3 that forms a part of the are connected together by, the said wall b1 and are,v provided on their inner surfaces with the cleats or angle irons b and b* in the manner shown more clearly in Fig. 3. Y

A cylinder C is suitably mounted Within the pit, and provided internally with piston mechanism of any suitable, known or desired character, which mechanism is connected with the said gate B by means of the upper and lower ropes or chains c and c1, whereby the said mechanism is capable of moving the said gate upand down about its horizontal and transverse aXis of movement. A valve c2, of any suitable, known or approved character, is provided for controlling the motive fluid byl which the piston mechanism is operated, and the said valve is preferably provided with a lever c3 by which it is operated. This lever is provided,y with a knuckle joint c* which permits the outer end portion caof said lever to swing upward, without operating the said valve, but which operates the said 'valve when the said lever is moved downward. A weight c, or any other suitable means, may be employed for holding the said lever in normal position, as shown in Fig. 3,- whereby the motive fluid is controlled to cause the piston mechanism to close the gate B by swinging it upward.

The bucket I) is of any suitable form or characten, and is adapted to fit between the .side `Walls b2 of the gate, and to enterl the seat formed by the angle iron cleats bs and b* disposed on the inne-r surfaces of said Walls, in the manner shown. in Fig. 3. Said bucket is provided with wheels d that travel P 'md 0WD in .the guides 1E. whlch latter .manner illustrated. The sides b2 of the gate are supported in any suitable manner, the said bucket bein provided with an operating connection 1 by which it is raised and lowered, and which permits it to tilt into the position necessary for receiving) the coal from the discharge openin of the in. One of the upper wheels of they ucket is provided with a laterally projecting axle or ]ournal d2 that strikes the lever portion c when the bucket descends into the pit, and which causes said lever to assume .the osition shown in Fig.- 1, as soon as the bue et has fallen over into the position shown. .This reverses the piston mechanism ofthe cylinder C, by manipulation of the valve 0*,causing the gate B to assume the position shown in Fig. 3, and thus carrying the bucket D into position Vfor loading. At about the time that the bucket assumes the osition shown in Fig. 3, and when it is entirely filled, the portion (l2 releases the lever c", t us permitting the weight c to operate the valve cz and thus again reverse the piston mechas' nism, whereby the gate and bucket are automatically brought back into the positionl shown in Fig. 1 Thenwhen the bucket is raised in the guides, the portion d2 strikes the under side of the lever` portion c, causing the latter to'assume'the position shown in dotted lines in Fig. 3; but as soon as the bucket has passed upwardly the said lever portion c falls back into the positionsliown in full' lines in Fig. 3, which latter position is the normal condition of the said lever.

During the time that the bucket is ascending inthe guides E, the iston mechanism of the cylinder C remains in position to hold the gate B in closed position. -When the bucket descends, the portion d again stiikes the lever portion c, bringing the latter into the position shown in Fig. 1, and the operation of filling the bucket is then repeated in the manner shown and described.

In this way the gate B serves not only to control the discharge of the coal from the bin A, but also to support the bucket and automatically bring the latter into loading v position, and then automatically return the ucket toa position for entering the guides. The bucket receives the discharge of coal directly from the bin, without the necessity of intermediate devices, and consequently the apparatus is both simplified and rendered more eflicient in service. The hoisting apparatus can be operated. rapidly without danger of breakage or other trouble.

While the bucket is filling, the sidcsb2 ofV the gate B serve as guards to. keep the coal from discharging .outside of `the bucket. Also, the ropes c and c1 are attached to the gate B at F, and are arranged to travel onV the upper and lower sheaves f and f, or in any suitable manner.
