To (1.7], whom it 712/u/7 0077,007

Be it known that 1, CHARLES M. TAYLOR, a citizen of the United States, residing at Lajunta, in the county of Otero and State of Colorado, have invented new and useful Improvements in Locomotive-Tenders, of which the following is a specification.

My invention pertains to locomotive-tenders, more particularly locomotive-tenders provided with means for pushing coal forward in the coal-pits thereof; and it has for its object the provision in a locomotive-tender of a coal-pushing follower of large capacity and adequate fluid-pressure means for moving the said follower forwardly and the arrangement of the fluid-pressure means in such position relative to the tender that the said means may begotten at with great facility in the event of repairs being necessary.

With the foregoing in mind the invention will be fully understood from the following description and claim when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a plan view, partly in section, illustrating a locomotive-tender equipped with my novel means for pushing coal forwardly, the follower of the said means being shown in its rear and lowermost position. Fig. 2 is a longitudinal central section of the same with the movable parts shown in one position by full lines and in other positions which they are capable of assuming by dotted lines.

Similar letters designate corresponding parts in both views of the drawings, referring to which- A is a locomotive-tender which may be of any construction compatible with the pur poses of my invention, though I prefer to construct it as shown in the drawingsthat is to say, with a coal-pit B in its forward portion, having an upwardly and rearwardly inclined back wall extending throughout the width of the tender, and side walls 5, converged forwardly from the back wall and having their forward ends arranged adjacent to the forward end of the tender.

C is the follower of my novel coal-pushing means. This follower C is preferably, though not essentially, shaped as shown in Fig. 1 and of a width corresponding to that of the wall a, and it is hinged at 0 to the tender, so as to lie flat against the wall a and swing forwardly from said wall, and is provided on the rear side of its upper portion with apertured lugs (Z.

D D are pairs of apertured lugs fixed on the top of the tender considerably in rear of the follower O.

E E are cradle-blocks fixed on the upper side of the tender at opposite sides of the longitudinal center thereof and slightly in rear of the follower U and having depressions e in their upper sides.

F F are cylinders arranged to rest on the cradle-blocks E and having rear heads f, on which are apertured lugs 1 hinged to the pairs of lugs D, so as to permit the cylinders to swing vertically after the manner indicated by dotted lines in Fig. 2.

(iii are pistons movable in the cylinders F and having rods /1/ extending forwardly through the forward heads of the pistons and hinged to the lugs on the follower U.

H is a transverse pipe connected at its ends to and movable vertically with the cylinders F and arranged to clear the lugs D.

K is a pipe arranged longitudinally of the tender, equipped with a valve L and adapted to be connected with a source of fluid-pressure supply on the locomotive complementary to the tender, and M is a hose or flexible conduit intermediate and connecting the pipe H and the pipe K. The source of fl uid-pressure supply mentioned in the foregoing may be either the steam-generator of the locomotive or the main reservoir of an air-brake apparatus carried by the locomotive, as desired, without involving a departure from the scope of or in any way affecting my invention.

In the practical use of my improvements the followerO normally rests against the back wall of the coal-pit B, and the said pit is charged with the coal in the ordinary or any other approved manner. At this point I deem it well to state that by reason of the follower G lying flat against the back wall of the pit B the said follower does not appreciably diminish the capacity of the pit. The function of the follower is to move the coal forwardly in the pit, so as to facilitate the removal of coal from the'pit by a locomotivefireman who stands on or adjacent to the forward end of the tender and by manipulating the valve L lets fluid-pressure into the cylinders F back of the pistons G. When fluidpressure is thus let into the cylinders, the pistons G will be moved forwardly and the follower U will be swung from the position shown by full lines in Fig. 2 to the position shown by dotted lines or through any fraction of such movement. On such movement of the follower the coal in front of the same will obviously be pushed forward and caused to settle on the bottom of the forward portion of the coal-pit. It will also be noticed that incident to the forward movement of the follower C the cylinders F will swing upwardly from their cradles or cradle-blocks E, as shown by dotted lines in Fig. 2, with the result that the leverage exerted by the fluidpressure means is materially increased. This latter will be appreciated as an important advantage when it is remembered that for reasons of economy it is well to use as little of the steam or compressed air of a locomotive for extraneous purposes as possible.

It will be gathered from the foregoing that my fluid-pressure means for actuating the follower G is entirely adequate to the demands placed upon it and yet is simple and inexpensive and has all of its parts so arranged relative to the tender that in the event of it being necessary to repair any of said parts access may be quickly and easily gained to said parts without in any manner affecting the tender.

l/Vhen my novel follower is in its foremost position (shown by dotted lines in Fig. 2) and it is desired to return the follower to its normal position (shown in Fig. 2) precedent to charging the pitB with coal, the same may be readily accomplished by the fireman entering the pit and pushing rearwardly on the upper portion of the follower.

It will be noticed that the piston-rods complementary to the fluid-pressure cylinders F are connected to the follower at points intermediate the vertical center of the follower and the side edges thereof. This is materially advantageous, inasmuch as it effectually prevents sagging of the side portions of the follower under the weight of coal imposed on said side portions.

Having described my invention, what I claim, and desire to secure by Letters Patent,

A locomotive-tender having a coal-pit, a vertically-swinging follower for moving coal forwardly in the pit; said follower being hinged at its lower end to the tender, a verticallyswinging cylinder arranged on and pivoted to the top of the tender at one side of the longitudinal vertical center thereof, a verticallyswinging cylinder arranged on and pivoted to the top of the tender at the opposite side of the longitudinal vertical center thereof, a pipe for supplying the rear portions of the cylinders with fluid pressure, and pistons movable in the cylinders under the action of fluid-pressure and connected to the follower at points intermediate the vertical center and side edges thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES M. TAYLOR.
