To all 'wfiom it may concern:

Be it known that I, CHARLES L.,'HEIsLnR, of Schenectady, in the county of Schenectady and State-of'New York, have invented a certain new and useful Improvement in Coal-Passers for Locomotive-Tenders, of which improvement the following. is a specification.

My invention relates to appliances for 'mechanically passing coal from the rear tothe forward portion of the coal bin of a'loco 'motive tender, in order to place it within convenient reach of the fireman for supply as required to the firebox of the locomotive; and its objects .are to effect a reduction of weight and cost in the construction of an appliance of such type; to obviate the necessity of expensive special modifications of tender construction heretofore ordinarily required for the application of such appliances; and to provide a self contained unitary mechanism, adaptable, without change, for application in connection with tender tanks of different designs and slope, and

which may be applied either singly, or in duplicate for coal bins of extra width, and

located so as not to obstruct access to the coal bin, while being at' all times readily accessible.

The improvement claimed is hereinafterfully set forth.

In theaccompanying drawings; Figure 1 is a view, partly in side elevation and partly in longitudinal central section, of a locomotive tender, illustrating an application of my invention; Fig. 2, a vertical longitudinal central section through a coal passer embodying my invention; Fig. 3, a plan or top view, partly in section on the line a -a. of Fig. 5, of the same; Fig. i, a front view, in elevation; Figs. 5 and 6, transverse sections, on t e lines b'-b and cc, respectively, of Fig. 2; Fig; 7 a plan or top view showing additional means for moving the fuel toward the coal carrier where the same is applied to a tender with a wide coal bin, or without sloping side walls; Fig. 8, a vertical longitudinal section of the same; Fig. 9, a front end view; and Figs. 10, 11 and 12, detail views of one of the vertically pivoted pusher sections carried by the horizontal shaft shown in Figs. 7 8 and 9.

Myinventionis herein exemplified as applied in connection with a locomotive tender of a present standard form, havinga water tank, 1, of so-called U form, with l the usual coal space or bin, 2, interposed between its longitudinally. extending side portions, at, and for some distance rearwardly from its front end. The central portion of the tank is forwardly and downwardly in'' clined at its frontend, the plates of which central portion constitute the rear wall, 3,

In the practice of my invention, a fluid pressure operating cylinder 4, the axis of with that of the downwardly and forwardly inclined rear wall of the coal bin, is secured to the top of the tank, adjacent to the rear wall of the coal bin. The cylinder 4, is fitted with a properly packed piston 5, secured upon a piston rod; 6, which passes through a stufling box, 4, on the front head of the cylinder. Fluid under pressure, as steam or compressed air,- is supplied to a valve chest-'7, located on the rear head of the cylinder, through a pipe, 7*, controlled by which is inclined at a'corresponding angle a cook or valve, 7 located within convenient reach of the fireman, and is admitted to and exhausted from opposite ends of the cylinder, to move the piston in alternately oppositedirections therein, as from time to time desired, by a distribution valve 8, of any "suitable and preferred known construction.

The well known Westinghouse air pump valve is one which is desirably adapted for this service, and is herein shown as applied.

A reinforcing wear plate 9', is secured to the rear wall of the coal bin and the adjoining portion of the floor thereof, which, in the instance shown, is the top of the water bqtom or central part of the forward portion of the tank. The lower end of the piston rod 6, is secured to a substantially T- shaped cross head 10, which is fitted to slide between guides 11, which overlap lateral flanges .10, on the central portion of the f "so I grooves in the plate sections.

rod; is protected from contact with-the fuel I in; the coal bin by a segmental shield, '15,

- carrier sections.

' vided withfjidownwardly projecting lugs,

13, on their lower sides'for the'reception' of the pins by which they are coupled to the carrier-sections. In the instance shown, one

pusher section is interposed between the cross head and the adjo ning carrier section another,between, the two" carrier sections;

ward end of the forward. carrier section, to

which it is coupled by a'hinge pin, 13"..

The forward and backward traverses of the .cross'head, 10, when actuated ,by the piston of the operating cylinder, are made over. the. surface of the inclined reinforcing 'wear plate .9, and those of the carrier sec tions and pusher sections over said surface, the surface of. the floor of the coal bin, and the connecting lower curvedsurface of the rear, wall 3-, the articulation of the sections "permittingth'em to follow the change of direction ofsaid I surface. v ,.-The true rectilineal movement ofthe sections is insured by a guide, 14;, which is secured to the floor of the? coal bin and fits in corresponding The pistol] extending from the operatingv cylinder to the line. of the upper end of the cross headwhen-the latter is at the forward extremity of its traverse. v p r The pusher sections, 13, are pivoted freely on their hinge pins, and are swung downwardly thereon in the rearwardtraverSes of the piston, by'thdpressure ofthe coal above them, into the positions shown. in dotted linesfin Fig. 2. They are correspondingly swung. upwardly, into the positions shown in .full l nes, by the pressure of the coal, in the "forward traverses of the piston. Ifv desired, rollers, 16, may

be mountedon the hinge "p1 n, -12", to asslst in supporting the carrier sections and diminishing the frictional resistan'ce to its movement.

In the operation of the appliance, the coal is moved forwardly in the coal bin by the action thereon of the pusher sections, 13, during the downward traverse of the piston, and thereby placed within reach of the firemansshovel, when working on the foot plate of the l0comotive,.the upward traverses of the piston returning the pusher sections to osition for succeeding operations The eading and characteristic feature of my inwhich, so far as my ormatlon extend, .it is vention, and one b knowledge and inf distinguished from the construction of the prior art, consists in an articulated coal pushing device,*adapted, by reasonof the articulation of its sections, to follow and conform to the planes of. the-floor and rear walls of the. coal bin, and, for its application a'ndoperation, lnvolving no change whatever in the form or relation of the boundaries of the co'al bin overwhich it l traversesy The practical structural and op erative advantage of this feature willbe obvious -to those familiar .with railroad service.

If the slope I ficientlysteep' to readily gravitate the fuel .pushers, 21, pivotally mounted on swinging arms 22, and operated by coupling rods, 23, connected to the cross head 10, may be provided, as illustrated :Fig. 7, of the drawings. i

When the sloping sections, 3*, ofthe side walls are omitted, or when using a single coal passer in a wide bin, additional-means may of the fuel from the sides toward the middle of th'e rear wall, 3, is not sufe employed forassisting the movement to the bottom of the bin, supplemental and athirdfis located adjacent to the forof the bin, As shown in- Figs. 7 to 12, such additional means comprises a transverse rocking shaft, 17 mounted in bearings, 19,-"

, in the opposite side walls of the fuel bin, a

short distance above. the bottom, the shaft being further supported by additional bearing brackets, 19, if desired, and carrying a plurality of downwardly'projecting pusher sections, 20, which are mounted to swing upon vertical hinge pins, 20*, supported in arms 20, fixed upon the shaft. For the pur pose of'impartinga rockingmotion to the shaft, the same is provided with a rigid arm, 18,-at its middle portion projecting downward, and coupled with one of the reciprocating carrier sections, 12. As the shaft is,

' thus oscillated-to and fro, the pusher sections, 20, swing through a limited angle about their vertical pivots, as determined by the stop lugs 20 always presenting an outward impelling face to the fuel upon the forward movement, and thereby moving the fuel away from the side walls and toward the carrier sections of the passer at the middle-ofthe bin.

It will, of course, be understood that two or more of the coal passer units may be employed in wide fuel bins, if preferred.
