To ail whom it may concern:

Be it known that I, OSCAR JOHNSON, a

citizen of the United States, residing at Chicago, in the county or Cook and State of Illinois, have invented certain new and useful Improvements in Locomtive-Tenders, of which the following is a specification.

This invention relates to improvements upon the form of tender shown in United States Letters Patent No. 675,795, issued to Edward Ryan and myself on June 1, 1901. One of the objects of the present invention is to provide means for preventing coal from getting between the hopper or hinged section of th coal-pit and the rear and side walls of the tender, and to accomplish this result without increasing the width of the tender over all, and thus decreasing its clearance. v

Another object of the invention is to provide means for holding the side walls of the hopper in proper relation to the side walls or" the tender body.

In the accompanying drawings, Figure 1 side elevation of a locomotive tender embodying the -features of my invention. Fig. 2 is a sectional view taken in the plane tot dotted line 2 2 of Fig. 1, but showing the far side of the tender. Fig. 3 is a section on line 3 3 of 1. Fig. 4- is a fragmental top plan view of the tender. Figs. 5 and 6 are detail views of one of the hinges for the movable section of the coal-pit.

In the form in which I have herein shown invention the body of the tender comprises side walls 1 and 2, between which, at the forward end of the body is the coal pit, the rear wall of the coal-pit being herein shown as consisting of a forwardly and downwardly inclined plate 3. The floor of the coal-pit is indicated at 1.

The hopper or movable section of the coalpit consists oi back plate 5 and two side plates 6 and 7 rigidly secured together in any suitable manner, and, if desired, strengthened in any preferred way, as by means out angle-irons'S. The rear end of the back'plate 5 may be curved upwardly, as shown in Fig. 1. The forward end of the hopper is pivotally connected to the tender body in any suitable manner, but preferably as shown in Figs. 4, 5 and 6. As therein shown, a suitable number of hinge-members 9 carrying pintles 10 are fixed to the wall 3. Upon the lower edge of the back plate 5 are secured hinge-members 11 having elongated openings 12 therein through which the intles 1.0 extend. It will be seen that if,

y any possibility, a fragment of coal should get between the inclined plate 3 and the back plate 5, undue stress upon or breakage of the hinges will be obviated, since the hinge-members 11 can move upwardly with relation to the hinge-members 9 to the extent permitted by the elongation of the openlugs 12.

13, 14. and 15 are transverse strips secured upon the inclined plate 3 and serving to support the back plate 5 at a slight distance from said inclined plate.

In order to prevent coal from dropping behind the hopper, I provide suitable means such as a vertical guard late 16 secured to the tender body rearwar ly of the rear end of the hopper, and to the rear end of said hopper I secure an angle iron 17 with its horizontal flange projecting rearwardly and overhanging the upperv edge of the guard plate 16. "If desired, the upper edge of the guard plate 16 may be arched as indicated in Figs. 1 and 3, in which event the angle iron 17 would be correspondingly curved.

As a further means to prevent coal from dropping into the s ace between the back plate 5 and the inclined plate 3 I provide a guard plate 18 fixed in the tender body near the upper edge of said guard plate lying close to the back plate 5 when the hopper is in its lower position.

In order to exclude coal from the space between each side of the hopper and the adjacent side wall of the tender body, I pro vide upon. the tender body a guard flange 19 which may, if desired, be a portion of a Z-bar 20, the Z-bar being fixed by'one of its flanges to the side wall of the tender body. In order not to increase the width over all of the tender, the Z-bar is preferably placed upon the inner side of the walls 1 and 2, as shown in Fig. 3. Upon each of the side walls 6 and 7 of the hopper is fixed a coliperating guard flange 21 which may also be a part of a Z-bar 22 secured upon the outer side of the hopper-wall in position to overhang the guard flange 19 when the hopper is in its lower position.

By reason of the location of the guard flange 19 upon the inner side of the tender wall, the adjacent side wall of the hopper is spaced away from the tender wall; and in order to close this space at the forward side of the hopper, I provide upon the inm nos-aces I nor side ofeach of the side walls of the ten- 1 between the side walls of the hopper and the I der body, a chafing box which may be of any suitable construction, but which preterably comprises a segmental plate 23 and two filler pieces 24 lying between the plate 23 and the tender wall. As shown in Figs. 2 and l the forward edges of the side walls 6 and 7 of the hopper lie close to the plates 23. As shown in Fig. 1, the chafing boxes extend forwardly from the hopper when the latter is in its lower position.

In order to prevent the side walls of the hopper from moving inwardly away from the side walls of the tender body, 1' provide on each tender wall a guide or retaining flange which is conveniently formed by err-- tending the plate 23 upwardly, as shown in Fig. 3, said extension being reinforced by attaching one or more plates 25 thereto. The upper edge of said curved upon the arc of a circle having as its center the axis of the hopper. 26 is a filler block fixed'to the forward end of the Z-bar22 upon the hopper ,(and upon the inner side of said Z-bar) to lie at the outer side of the guide flange formed by the

plates

23 and 25. It will be seen that said guide flange, acting in conjunction with the 2- bar 22, holds the side wall of the hopper in operative relation to the side wall of the tender body.

- moves the gate.

The hopper may be tilted byany suitable means, as for example, that fully described in the before mentioned Letters Patent. I have deemed 'it unnecessary to illustrate such means in detail herein, an actuating cylinder, however, being represented at 27, and 28 being a rod attached at one end to the hopper and at its other end to a piston in the cylinder. Steam may be admitted into the cylinder below the piston through a pipe 29 connected to the locomotive boiler. In use, the forward open end of the coal pit is closed by any suitable means, such as the ordinary removable gate (not shown) until all of the coal readily accessible has been removed, whereupon the fireman re- Steam may then be ad mitted to the. cylinder 27 to tilt the hopper forwardly a slight distance in order to cause the coal lying in said hopper to slide forwardly into convenient reach 01 the tireman. The hopper 5 may thus be tilted forwardlyfarther and farther each time until all of the coal has been deposited within the firemans reach. When the coal pit is being filled, the hop per isin its lower position, as shown in full lines in Fig. 1, at which time the guard members 16, 17, 20 and 22 prevent coal from opping into the'space between the hopper and theadjacent parts of the tender body. While the hopper is being tilted forwardly the chafing boxes and the guard'mcmbers 22' and 25 prevent coal from working in guide flange is side walls of the tender.
