ICOAL-CHUTE.

SPECIFICATION forming part of Letters Patent No. 252,055, dated January 10, 1882.

' Application filed August 3, 1881. (No model) 7 To all whom it may concern:

Be it known that I, JAMES D. Pn'rrrr, a oiti zen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in GoalOhutes; and Ido hereby declare the following to be a full, clear, and exact description of theinvention', such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying; drawings, and to letters or figures of reference marked thereon, whichform a part of this specification.

This invention relates to improvements in coal-chutes of that class used for loading coal int?) locomotive tenders 5 and the invention consists, first, in a box or chute mounted in a frame in such manner that when loaded with coal it will by gravity slide forwardso'as to bring its discharge end over the tender, and may be returned after discharging its coal by counter-weights, springs, or other devices.

The invention further consists in a catch adapted to hold the gravitating chute in its position when loaded, and also in its position when unloaded.

The invention further consists in constructions and combinations hereinafter described, and set forth in the claims hereto annexed. V

' In the accompanying drawings, which illustrate my invention, and in whichthe same reference letter indicates the same partin the different figures, Figure lis a perspective. Fig. 2 is a side elevation. Fig. 3 is a top plan. Fig. 4 is an .end elevation of chute.

Referring to the, drawings'by letters, letter A represents a frame, whichmaybe of any desired construction that will support bars B B at each of its sides, which bars are somewhat lower at one end than their other end and form the track for the chute to run upon, as hereinafter described.

0 is the chute, having sides 0, end or door 0, and bottom 0', which descends orinclines toward the end 0. The bottom 6" preferably extends slightly beyond the end 0, and has side boards, 0, on its projecting end. The end G is hinged at its upper end, so that its lower end may swing outward, as shown by dotted lines at Fig. 2. D D are gravitating latches pivoted at d d, respectively, the outer the door 0 in a closed position.

ends of which latches drop by gravity into notches d in the side boards, C", and hold The inner end of the latch D rests upon the adjacent end 5 5 of the latch D, so that raising the outer end of the latch D to release it from the notch in the side board will also raise the outer end of the latch D and rcleaseit, as shown by dotted lines at Fig; 4.

E is agravitating catch, pivoted at one end to the outer end of the latch-bar D, and pro jects forward through a slot in a bar, 0, of the chute. 'VVhen the door 0 is opeua shoulder or notch, e, on the catch E will engage with a catch, 1:, on the bar 0 and hold it open, as shown by dotted lines at Fig. 2. 7

An upper bar, B, is located 011 each side of the frame A, and wheels F, one on each side of the chute, and near its upper rear end, are 70.

adapted to run on the bar B, while similar wheels, F, support the forward end of the chute and run on the bars B. i

G G are pulleys carried on a shaft, H, which is journalcd in suitable bearings near the rear 7 end of'theframe A. Uords or chains I, attached to the bottom of the chute A, extend over the pulleys G and carry counterpoise-weights l on their rear ends. The weight of the. counterpoises I should be such that when the chute or car G is unloaded the-counterpoises will be heavy enough to draw the car back to the po sition shown by dotted lines at Fig. 2.

J is a guide-bar, fixed to the side of the chute or car 0, and has a notch, j, at its front end and a notch,j, at its rear end.

K is alatch-bar, pivoted near its mid-length portion to a standard, L, which projects from the frame A. The rear end, K, of the bar K isthe heavier, and is turned inward and rests 0 on its guide-bar J, so that when the chute O is drawn back, as shown by dotted lines at Fig.

2, the end K will fall into the notch j and hold the chutein said position. The forward end of the latch K carries a hand-hold rod, M, which 5 may be drawn downward to raise and release the end K from either notch j or j.

Nis a stop, against which awheel, F, strikes to limitthe movementof the chute forward, and N are stops which strike the frame A to limit 10') its movement rearward. The stops N are also projected over the projecting end of the trackcoal.

bar B, as shields to protect it from the coal which may fall thereon. I

In operation the chute, when empty, stands in the position shown by dotted lines at Fig. 2, where it is held, as hereinbefore described. While in this position it may be filled with The frame A is located near the railway-track, so that the locomotive tender may be brought near to the discharge end of the chute, when by pulling down on the rod M the latch K will be released from the notch j, and the weight of the coal overcoming the weight of the counterpoises I. the chute will run forward on its wheels F F to the position shown by full lines at Figs. 1 and 2, Wii 11 its discharge end projecting into the upper open side of the tender. The'latch-bar D may now be raised, as hereinbefore described, to release the door (.1, when the coal will force it outward, and Sliding down theinclined bottom 6 will be discharged intothe tender. The coal in escaping will force the door b outward until the latch E engages with the catch 0 to hold it open, as hereinbefore described. When the coal has escaped from the chute the latch E may be raised slightly to release it and allow the door 0 to close by its own gravity, the latches D D sliding up over the inclined sides of the side boards, 0, and engaging with theirrespectivenotchestherein. When the chute was run forward by the gravity v of the coal, as last described, the latch K slid What I claim as new is- 1. In combination with a frame in which it is mounted, a coal chute adapted to be carried forward and project from the frame over a locomotive tender or receiver by means of the force of gravity of the loaded chute.

2. The combination, with the gravitating chute or box and supporting-frame, of a latch, K, and catch j, for holding the chute in a position projected from the supporting-frame, substantially as and. for the purpose specified.

3. In combination with the supporting-frame and gravitatin g chute, having counterpoiseweight I, and guide-bar J,haviug notchesjj, the gravitating latch K, adapted to engage the notcbesjj and to slide upon the bar J, substantially as and for the purpose specified.

4. In combination with the gravitating chute, having a bar, J, fixed thereto, with notchesjj in its ends, a latch, K, adapted to engage said notches, substantially as and for the purpose specified.

5. In combination with the chute O and hinged door 0", the latches D D, adapted to engage the side boards, 6, to hold the door 0 closed, and their adjacent ends overlapped, so that raising the outer end of one will release it and also act upon the other to release it, substantially as and for the purpose specified.

6. In combination with the chute, hinged door, and latches D D, the gravitating latch E, hinged to one of the latches, D or D, and adapted to engage a catch on the side of the chute, substantially as and for the purpose specified.

In testimony whereofi affix my signature in presence of two witnesses.
