IMPROVED RAILWAY WATER-ELEVATOR.

The Schedule referred to in these Letters vPatent and making part of the same.

To all wha-m 'it may concern:

Be it known that I, ARTHUR A. STIVENDER, of Ocala, in the county of Marion, and State of Florida, have invented a new "and useful Improved Apparatus for Elevating Water into Railroad-Tanks, by means of passing trains; and the following is a sufficiently full, clear, and exact description to enable one skilled in the art to which my invent-ion appertains to carry it into full effect, reference being had to the accompanying drawings, which are made part of this specification.

My improvements consist, first, in a novel construction, combination, and arrangement of parts, to adapt the pump to be operated bymeans of a heavy weight, elevated by the passing t-rain, instead of being operated direct, as heretofore. Also in a novel provision for adapting said weight to automatically throw its elevating devices in and out of gear, as required. a superior mechanism for transmitting the motion to theweight-elevating drum, of a treadle, adapted to receive two posit-ive movements from each wheel passing over it, and to operate without the aid ofsprings.

In the drawings- Figure 1 is a plan view, partly in horizontal section;

Figure 2, an end or transverse elevation, looking in the direction indicated by the arrow l;

Figure 3,11. side or longitudinal elevation, looking in the direction indicated by the arrow 2, iig.' 1; and

Figure 4, an elevation of a portion of the track, looking in the direction indicated by the arrow 3, tig. 1, a fragment being broken away to expose the treadle.

A represents the track', which may be supported in the same manner at this as'at other points, and which may be of any usual form, with the exception of a section,B, which forms a part of the apparatus proper, and which may be composed, asshown, of two vertical plates, suitably secured together, and serving to receive, between them, a treadle, 0, by which to receive the requisite movement from the wheels of the cars, as they pass over the track. This treadle is ful,- crumed in the centre, where its upper surface is bclow, or at the surface of the rail, and its two ends are so shaped as to be readily engaged by the wheels, passing in either direction, and so proportioned as that, on the depression of one, the other shall project a sufficient distance above the level of the rail, as, by its depression t'o said level, to give the desired movement, and also that its two ends shall be in turn acted on by each wheel. Each end is in turn elevated by the depression of the other, and the use of springs, forthis purpose, is thus obviated..

The treadle C is keyed to a shaft, D, mounted in suitable bearings, and provided, on its outer-end, with Also, in the employment, in combination with` an arm, D', by the oscillation of which, by the movemeut of the treadle, described, the elevating-meca anism is actuated.

A frame, E, of suitable form and dimensions, ar-

ranged in convenient proximity to the track, provides weight, K, guided by the standards of said. frame,

serves, by being wound 'up on said'drnm, to elevate said weight.

The shaft L, of thedrnm F, has keyed to it a pinion, M, vwhich is meshed into by a spur-wheel, N, on a parallel shaft, O, which also carries a ratchet-wheel, P, to which a continuous rotary motion, in a direction to wind `the rope G on the drum F, and elevate the weight, is imparted by the oscillation of the arm D of the'treadle-shaft D, through a suitable clutch-arrangement.

The ratchet-wheel P is engaged by two spring pawls ordogs Q Q, each attached to one end ot' a separate bell-crank lever, R R, the other ends of which are con` nected by a link, S, carried by the upper end of the oscillating arm D', which is there slotted to allow the vertical variation of its end, and said link.

A tripper, T, of suitable form,is supported on the' shaft O,and provided with an arm, T', so arranged as, by its elevation,tbe pawls or dogs Q shall be thrown and held out of contact with the ratchet-wheel P, and the weight be allowed to descend, a spur-wheel, U, mounted loosely on tte shaft L, of the drum F, and connected therewith by a pawl and ratchet, V W, or 4other suitable clutch-arrangement, being then rotated, and through a pinion, X, and shaft Y, or lother suits.,- ble intermediate mechanism, operating the pump Z,- which may be a rotary, as shown, or of other vpreferred form.

The continued oscillation of the treadle, after the clutch is tripped, has no eect on the apparatus, other than the actuation of the shaft D, and the pawls Ior dogs Q, and'their connections, the pawls simply sliding on the arms of the tripper T.

The arm T', of the tripper T, is actuated by an arm, a, of a gravitating rod, b, actua-ted by the weight itself.

, Said rod works in suitable guides, on one of the standards of the frame H, and is provided, at its upper end, with an armor tappet, c, by the engagement ot' the weight with which, it is elevated, and the clutch ot' the elevating-mechanism, tripped, and at its lower end, with one or more notches, d, by the engagement of a spring pawl, e, with which, itis heldin its elevated position, and which is provided with an arm or tappet, f, by the engagement of the weight with which it is released and allowed to descend, by gravity, depressing the arm T', of the tripper, and releasing the clutch of the elevating-mechanism, so as to cause the weight to be again elevated.

The arm a, of'the sliding rod b, is prvided with. a vertically elongated slot, for the reception of the end of the arm T of the tripper, and said arm T is provided, on its under side, with a downwardly-projecting spring, T2, which serves to receive the action of the tripping-movement of said arm (l,`and transmit the saine to the arm T1, with suicient force to press the arms ot' the tripper in Contact with the pawls or dogs Q, when their next movement, by the treadle and its connections, serves to throw them out of con'nection, which requires considerable force, owing to the weight being supported onI them, and the iinal movement of said tripper, to so press said-pawls or dogs away from the ratchet-wheel, as to prevent their coming in contact with it in their next movement, is accomplished by the spring itself. I am thus "enabled, more completely, to utilize the action of the treadle, and also to prevent the straining of any rarts, which might otherwise occur.

The amount and character of the gearing, between the clutch or ratchet-shaft and that of the elevatingdrnin, may be varied, as desired, and any usual or suitable mechanism, other thant-hat described, may be employed, to convert the oscillating motion of the treadle-shaft into a continuous rotary motion, if prefel-red.

The anangement of' the apparatus may also be varied` as described. The frame H may constitute a part of that employed to support the tank, or may be a sepa-rate structure, or the weight may be guided in suitable ways, arranged in or supported by the tankirame. Two or more treadles may beemployed in one or both rails of the track. l

I propose so regulating the height of the frame of the weight, and the character of the elevating-mechanism', as that a train of four cars, besides the locomotive and tender, shall complete its elevation. But

this is not essential, as the return movement of the weight, by the tripping provisions described, will certainly commence on its reaching the top of its frame, and not until then, unless it be desired, and no injury to the apparatus can result from the operation of thev treadle and its connections, during this part of the operation.

The pump, being operated by a Weight elevated by the action of the treadle, the operation to be performed by said treadle maybe done 'at great speed as effectively as slower, whereas, were the action to operate the pump direct, as in all apparatus of this character prior to my invention, it could not operate, were the trains to be run rapidly by, as the operation of pumping cannot eciently be performed at a high speed. Besides, I am thus enabled to run the pump for any desired length of time, and to more readily increase the power, andthe relat've number of revolutions or strokes produced, than is possible in an apparatus of the oldform.

The tripping-provision renders the apparatus substantially automatic. g

The construction of treadle adapts twice the number of movements usually gotten from a single treadle to be secured, and any necessity for springs to elevate it, is obviated.

Having thus described my invention,

I claim as new therein, and desire to secure by Letters Patent- 1.
