`To all 'whom z't'may concern Be it known that I, DAVID A. LEE, a -citizen of the United States, residing at Centerville, in the co-unty of Appanoose and State of Iowa, have invented certain new and useful Improvements in Coaling Systems, of which the following is a specificatio-n, reference being had therein to the ac- Y companying drawing.

This invention relates to coaling systems for railroads using steam locomo ives, and the principal objectfof the invention is to provide an improved vdevice whereby the motion of the locomotive along thetrackVV will serve to elevate the coal and deposit the same in the tender.

With the abo-ve and other objects in view, i

- hooks used in connection with the dumping mechanism. Fig. 5 is a side elevation of a portion of the locomotive tender equipped for use in connection with this device. Fig. 6 is a detail view of the lower part of this device showing the same used in connection with an automatic feed hopper, the door of the hopper being closed. Fig. 7 is a similar detail showin the bucket in lowered position with the door of the hopper open. Fig. 8 is a plan view of this portion of the devlce.

This invention includes a tower constructed of suitable structural material, and

l is provided with corner posts 10 tied together at intervals by means of braces 11, and having their tops connected by bars 12. The tower is furthermore braced with diagonal members 13 and is equipped with L- shaped guides v14, which extend diagonally from' the rear to the front. At the upper end of these guides 14 there is provided on the front members 10 suitable eyes 15 arranged foi` the reception of a rod 16. Extending diagonally across the top of the tower is a pair of angle braces 17 between which yare mounted guide pulleys 18. Adjacent the bottom of one of the members 10 is a third guide pulley 19 and positioned in spaced relation to the tower is a pulley 2O.V

Slidably mounted in the guides 14 is a.

bucket 21, which hashinged to its bottom a bail 22, the latter bein held by suitable eyes 23. Secured to the iight of the bail 22 is a hoisting rope or cable 24, which is trained over the guide pulleys' 18 under the pulley 19, and aroundthe pulley 20.-/ Upon v.

the endof thiscable 24 there vis provided a hook 25 which is arranged to engage an eye secured to theV side of the engine ten- On what may be termed the front of the bucket 21 there is provided a plurality. of eyes 28 to each of which is connected a hook 29, the bill whereof faces outward so that' as the bucket is drawn up by the guides these hooks.,wi1l engage the bar 16. In order .to prevent-the bucket being drawn to too great a height a. suitable foundation 30 is madev adjacent the track 31 and in this founda- Ation isv sunk an eye-bolt 32 which is engaged by.one end of a chain 33,' the other end beif ing connected to the hook25.

'In the operation of. the device the bucket is loadedwith coal in its lowered position.

The ho-ok- 25 is engagedwiththe eye 26 on the tender and the engine moved forward-- bodily is prevented, but as the engine proceeds the'bottom of the' 'bucket is drawn upward so that the same revolves about the bar 16 and the load of coal is dumped into the tender. If by any chance the engineer fails to stop the engine at the proper time the chain 33 will prevent tot) great movement.

With this type of bucket it is preferred to use a charging hopper of novel construction now to be described. At the rear of the tower there is provided a track the rails whereof are indicated at 33 for coal cars and this track extends over a hopper having a downwardly inclined bottom 34 and slant- 4ing sides, and a rear end, as indicated at 35 and 36, respectively. The front of the hopper is preferably disposed vertically although the same may be inclined outwardly shown in Fig. 7, this lower part contactingV with the bottom of the hopper to retain it in the said position.`I The hopper is normally raised from the ground and supported on suitable standards 41 and at the bottom of the tower there is 'a well 42 wherein the bucket rests when in its lowermost position so that the bucketis beneath the mouth of theghopper. On the underside of the hop- Yper is secred-fsprii1g"latch 43 provided with a shoulder 44 so arranged that when the door 39 is closed the lower end thereof Will engage against this shoulder, and hold the door in its closed position until re leased. For'tii'e purpose of releasing the door the spring latch 43 is provided with a downwardly extending end 45 against which the rear of the bucket 21 is adapted to contact when in its lowermost position. In the operation of this part vof the device as the bucket comes down empty the rear wall thereof strikes the end 45 and depresses the spring latch 43, 'thus releasing the door and permitting it to assume the position shown in Fig. 7. After the bucket has been filled and starts on itsupward ourney the upper end of the rear wall strikes the door 39 and forces it to closed position at the same time that the spring latch is released from "engagement with said rear wall so that it is in position to hold the door closed when the same is closed by the upward movement of said bucket. I

There has thus been provided a simple and eliicient device of the kind described, and for the purpose specified.

It is obvious that many minor changes may be made in the form and construction of the invention without departing from the v f material principles thereof, and it is therefore not wished to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly come within the scope claimed.

Having thus described the invention what I claim asnew is A 1. In a device of the kind described, a skeleton frame constituting a tower, a bar extending across the ront'of said tower, inclined guide-ways leading upward from the back of the tower to points on the front of the tower below the top, a bucket slidably mounted in said guide-ways, hooks on said bucket adapted to engage said bar, guidepulleys carried by said tower, 'a guide pulley located in spaced relation to the tower, a bail secured to the bottom of said bucket, a rope led over said guide pulleys and provided at one end with a hook adapted for engagement with a portion. ofiagoving car, the otherend of said rope being seured to said bail, and a chain having one end secured to a fixed object and the other end secured 'to said hook. l Y I 2. In a device of the character described` a guide-way, a bucket movable within said guide way, ahopper adjacent the bottom of said guide way, said hopper being spaced above said bottom and to therear thereof, said hopper being provided with a front wallhaving a door opening therein, a door plate hinged intermediate its ends at the lower edge of'said opening, the lower part of said plate extending beneath said hopper and being arranged to contact with the underside of the hopper when opened, a spring latch having one end' secured beneath said hopper Aand being provided with a shoulder portion arranged to engage the lower edge of the door plate whenvthelatter is closed to retain the same inV closed position, and a projecting end on said latch adapted for engagement with the rear wall of the bucket when the latter is lowered.

In testimony whereofI hereunto aiix my J. E. SwArroRD.
