Serial No. 777,138. i 1

To all whom it may concernv le it known that I, CHARLES L. Heisman,

ot' Schenectady, in the county of Schenecl tady and State of New York, have invented a certain new and uset'ul Improvement in Coal- Passers for Locomotive Tenders, of which improvement the following is a specilication. l My invention relates to appliances'-v for mechanically passing coal from the rear to the forward portion of the coal bin of a locomotive tender, in order to place it within convenient reach of the tireinan 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 -tlie 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 applicationin connection with tender tanks of dierent designs and slope, and which may be applied either singly, or in diiplicatefor 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 hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a View, partly in side elevation and partly j in longitudinal central section, of a locomotive tender, illustrating an application of my inrention; Fig. 2, a vertical longitudinal central section Athrough a coal passer einbodyinginy invention; Fig. 3,a plan or top view, partly in section on the line a a of .'Fig. 5,; of the same; Fig. 4, a front view,

ilyfinvention,ishereinexempliti'ed as ap` plied in connection 4with a locomotive tender of a present standard form, haying a Wat-er tank, il, of so-called U form, with the usual coal .space or bin, 2, interposed between'ts longitudinally extending side portions, at, and tor some distance. rearwardly from, its front end. The central portion of the tank is forwardly and downwardly inclined at its front end, the plates of which central portion constitute lthe rear wall, 3 of the coal bin. The side walls ofthe fuel' in may also have an inclined or'sloping portion, 3b.

The forward end of the coal bin is controlled by a movable coal construction.

In the practice vof my invention,` a fluid pressure operating cylinder, 4, .they axis 'of which is inclined at a Correspondingffany le lwith that of the downwardlyand forwar 1y 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, se cured upon a piston rod, l6, which passes through a stuiting box 4j1, on 'the Ifront head of the cylinder. Fluid under pressure', as steam or compressed air, is'supplied to a gate, 3, ot the ordinary valve chest, 7, located on the 'rear` head of COAL-PASSER FOR LOCOMOTIVE-TENDERS. u

the cylinder, to move'the pistonA in ,alter-W nately opposite directions therein, as from time to time desired, by a distribution valve, 8, of any suitable and preferred` known construction.

The well knownk Westinghouse.,

air pump valve is one which isI desirably adapted for this service, and is hereinshown as applied.

A reinforcing wear plate, 9, is secured to the rear wall of the coal binand the adjoin-A ing portion of the floor thereof, which, in the instance shown, is the top ofthewater bottom or central partof the forward portion of thetank. The lower end of the pis ton rod, 6, is secured toa substantially T shaped cross head. 10, which is fitted toslide between guides, 11, which overlap llateral flanges, 10, on the central portion of the cross head, and aresecured to the wall,.3,

f and rwear plate, 9, by bolm, 11. An articulatedA ramycomprising aplurality of carrier sections, 12, and one or more vibratable pusher sections, 13, is coupled tothe cross head, 10, by atransverse hinge pin, 12., and the carrier sections lare coupledone to another by similar hinge pins, 12b, said pins passing through lugs on the cross head and carrier sections. The pusher sections, 13, which are of substantially rectangular form, and may be toothed or serrated on their upper sides throughout the whole, or any desired portion, of their length, are provided with downwardly projecting lugs, 13,

on their lower sides for the reception of the p ins by which they are. coupled tothe carr1er sections. In the instance shown, one

"pusher section is interposed between the' cross head and the adjoining carrier section; another between the two carrier sections, and a third is located adjacent to thev forward lend of the forward carrier section, to `which it is coupled by a hinge pin, 13b.

The forward and backward traverses of the cross-head, 10, whenactuated by the piston of the., operating cylinder, are made over the'surface of the inclined reinforcing wearl plate, 9, and those of the carrier sections and pusher sections over said surface,

the surface of the floor of the coal bin, and the connecting lower curved surface of the rear wall, 3, the articulation of the sections permitting them' to follow the change of direction of said surface. The true rectilineal movement of the sections is insured by a guide, 14, which is secured to the floor of the coal bin and fits in corresponding grooves in the plate sections. The piston rod is protected from contact with the fuel in the coal bin by a segmental shield, 15, extending from the operating cylinder to the line of the upper end of the cross head when the latter is at the forward extremity of its traverse.

The pusher sections, 13, are pivoted freely on their hinge pins, and are swung downwardly thereon, in the rearward traverses of the piston, by the pressure of the coal above' them, into the positions shown in dotted lines in Fig. if.' They are correspondingly swung upwardly, into the positions shown in full lines, by the pressure of the coal, in the forward traverses of the piston. If desired, rollers, 16, may be mounted on the `hinge pin, 12b tolassist in supporting the carrier sections and diminishing the fricvtional resistance to its movement.

In the operation of the appliance, the coal is moved forwardly in the coal bin by the action thereort of the pusher sections, 13, during the `downward transverses of the pist-on, and thereby placed wit-hin reach of the firemans shovel, when working on thefollow and conform tothe planes of the ioor and rear walls of the coal bin, and, for

its application and operation, involving no changerwhatever in the form or relation of the boundaries of thecoal bin over which it traverses. The practical structural and operative advantage of this feature will be obvious to those familiar with railroad service.

If the slope of the rear wall, 3, is not suiliciently steep to readily gravitate the fuel to the bottom of the bin, supplemental pushers, 21, pivotally mounted on swinging arms, 22, and operated by coupling rods, 23, conf nected to thevcross head, 10, may vbe provided, as illustrated inFig. 7 of the drawings A n, v

When the sloping sections, 3b, of the side walls are omitted, or when using a single coal passer in a wide bin, additional means may be employed for assisting the movement of the fuel from the sides toward the middle of the bin. As shown in Figs. 7 to l2, such additionalA means comprises a transverse rocking shaft, 17, mounted in bearings, j19, in the opposite side walls of the fuel bin, a short distance above the bottom, the shaft being further supported by additional bearing brackets, 19a, 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 purpose of imparting a rocking motion to the shaft, the same is provided with a rigid arm, 18, at it-s 'middle portion projecting downward, and coupled with one of the reciprocating carrier sections, 1Q. 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, 20c, 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 Amiddle of the bin. Y j

It will, of course, be understoodthat two or more of the ,coal passer units may be employed in wide fuel bins, iif preferre d.
