To all whom it may concern:

Be it known that I, EDWARD E. JOHNSON,

a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Railway VVater-Columns, ofwhich the following is a specifica-' tion'.

. This invention relates to improvements in railway water-columns or devices of that class which are more particularly intended for supplying water to locomotive-tenders and which comprise a stand-pipe located alongside of a railway-track or between two such tracks, and a laterally-extended spout on the stand-pipe to be turned either at right angles to the tracks to supply water to locomotive-tenders or parallel to the track to avoid the passing trains when not in use and also adapted to be swung vertically throughout a considerable range of movement for the purpose of bringing the mouth of the spout into immediate proximity to the tank-openings of tenders of various heights and of avoiding the coal which is piled on the tenders above the water-tank.

he present improvements have relation particularly to the most desirable type of this class of apparatusnamely, the type in which the spout'is pivoted to the stand-pipe at a point below the end thereof and telescopes at its inner end loosely over the downward-turned end or nozzle portion of the stand-pipe.

One of the defects of railway water-columns of this kind, as heretofore constructed, has been that the end of the spout in movin downwardly swings to one side of a vertica line of descent to such an extent as to carry it laterally beyond the tank-opening or water-hole of the tender, either at the upper or lower or at bothlimits of its movement; and a principal object of the present invention is to avoid this difficulty by mounting the spout in such manner that the arc of movement described by the end of thespout, even when the. range of movement provided is unusually greatsix feet, or more-will so closely ap proach a direct vertical line as to keep the spout at all times in proximity to the tankopening whatever the height of the tender.

A further object of the invention is to provide water-courses free from obstruction and abrupt chan es of direction and a spout draining quiclily away from the stand-pipe and not liable to be inoperative from freezing; and other objects are to provide an improved mounting for the water-colun1n tending to automatically return the column to its position of parallelism with the tracks when not in use; also, to provide an improved valve mechanism for controlling the flow of water through the column, and to provide various other features of improvement in the column itself.

To these ends the invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims, when considered in connection with the accompanying drawings, in which Figure 1 is a side elevation of a railway water-column constructed in accordance with my invention, the foundation and pit for the base of the column being shown in section. Fig. 2 is a top plan view of the column illustrated in Fig. 1. Fig. 3 is a vertical section of the worklng parts of the valve shown in Fig. 1, these parts being shown in the position they occupy when the valve isclosed. Fig. 4 is a sectional view of the same valve, including its connections with the inlet-pipe and water-column and showing the working parts in the position which they occupy when the valve is open. Fig. 5 is a top plan section taken on line 5 5 of Fig. 4. Fig. 6 is a top plan section taken on line 6 6 of Fig. 4. Figs. 7 and 8 are vertical sections of the valve mechanism, showing the parts in different working positions from t 1086 occupied in Figs. 3 and 4. Fig. 9 is a vertical section of a simplified form of the valve mechanism designed to be entirely operated by hand. Flg. 10 is a vertical sectional detail taken through the standard which su ports the Water-column. Fig.. 11' is a top p an section thereof, taken on line 1'1 11 of Fig. 10. Fig.

12 12 of Fig. 10. Fig. 13 is a sectional detail taken on line 13 13 of Fig. 1 and showing the valve-operating connections at the lower end of the stand-pipe. Fig. 14 is a fragmentary detail of a portion of these connections. Fig. 15 is a top plan view of the latticed framework, showing the manner in which the operating-lever is mounted therein. Fig. 16 is a sectional detail taken on line 16 16 of Fig. 15.

As shown in said drawin s, the water-column C comprises a vertical stand-pipe 1, to the lower end of which water is admitted through a suitable valve 2 and from the upper end of which water can be discharged through a spout 3. The lower end of the 12 is a top plan section thereof, taken on line I stand-pipe and its'valve 2 are shown as inclosed within'a pit P, from which the standpipe emerges through a tubular standard 4, within which the standpipe 1 is free to 'swivel upon a vertical axis. For security and permanence of construction the stand ard 4 is herein shown as cast with a flange 5, which rests upon I-beams 6, that extend across the pit and are buried at their ends in its masonry walls, the standard and column bein thus suplported independently of the plan top p of t e pit and not affected by any shrinking or warping of the plank. A frostfloor p is shown as extending across the pit some distance below its top 10, but above the valve 2 to prevent the latter from freezing up.

' As hereinbefore stated, a principal feature of the present construction consists in the peculiar manner of maintaining the spout 3 on the standipe 1 in such way as to permit ofthe vertical swinging of the spout through out the desirable arc of movement'with but little lateral deflection of its outlet. To this end the spout is shown as carried by a latticed framework 7, which is pivoted at its inner end to oppositely-projecting lugs 8 to the standipe at a point 8 near the top of the latter, an approximately opposite the middle point of t e arc the delivery end of the spout is usually re uired to describein being adjusted to tan s of the average height. The framework carries at its outer end an annular collar or band 9, that encircles the spout and rigidly supports it in the framework. The spout itself is an entirely separate piece from the stand-pipe and, except for the framework 7 and for a brace 7 between the inner end of the spout and the inner end of the framework, has no permanent gooseneck 10, the curved middle portion of which extends a considerable distance back of the column on the opposite side from the spout 3 and tends to balance the Wei ht of the spout and to thus relieve the stan pipe from sidewise strains, while permitting a sufficient movement of the spout over the mouth of the gooseneck to permit its inlet end to extend to a point back of a vertical line drawn through the pivot 8 when the spout is in its uppermost position and at the same time insure such a position of the spout that it will drain freely away from the stand- 1- e. p uitable means, such as coiled sprin s inclosed Within rotecting-tubes 11, are s own as stretched etween the frame 7 and the back of the gooseneck 10 to normally maintain the spout in its raised position, these springs being at the same time so applied mam that leverage of the spout against them will 'increase as the spout is depressed, so that 'when the spout is in its lowermost position its weight will overcome the tension of the springs and prevent thelr the spout again except by the assistance 0 the opera tor.

The latticed framework being stiffened swivel within the standard 4, as before stated.

The flow of water through the stand-pipe is controlled by an operating-lever 13, which extends along the inner under side of the framework 7 to within convenient reach of the operator as he stands upon the tender. This lever is pivoted to the frame 7 at 14 and at its inner extremities is pivotally connected with the upper ends of vertical rods 15, the lugs 8 being laterally curved to permit this connection with rods 15 to be made in vertical alinement with the pivots 8. The rods 15 extend centrally down each side of the standipe to a point on the latter below the frost-- oor of the pit. Here the lower ends of the rods are secured to a ring 16, which loosely encircles the stand-pipe and passes between lugs 17 on a forked lever 18, which latter is secured at its forked end to the valve-casing by links 19 and is connected at its other end 20 to the upper end of the stem of the valve 2. from twisting on the stand-pipe by sliding loosely through guide-holes in a ring 21, that is clamped about the pipe just below the ring 16, Fig. 1. With this construction the swingin up and down of the spout 3 may obvious y take place without affecting the valve, while the valve-operating lever may itself be moved upon the frame in any position of the spout to admit water to the standpipe or shut it off therefrom, as desired. The outer end of the lever 13 is shown as projecting through and uided by a loop 13, which is located on the ame 7 at one side of the spout and is provided with a stop-lug 22, beneath which the end of the lever may be thrust to hold the valve open while the colunm is delivering water.

The weight of the stand-pipe and spout is herein shown as supported upon an inner annular shoulder 25 of the standard 4 by a number of antifriction-rollers 26, that are inserted between the shoulder 25 and an opposing flange or annular ring 27, which latter encircles the stand-pipe and is rigidly clamped thereto by set-screws 28, Fig. 10. The roll- The rods 15 are prevented IIO ers 26 are shown as loosely mounted within a cage 29, that is recessed at 29 toreceive them and is also recessed at 30 to receive horizontal rolls or disks 30, that are inserted between the ring 27and a flarin or bell-like mouth 33 to the standard 4. hisdouble form of bearing serves to support the standpipe with but little friction, notwithstanding the fact that the spout rojects laterally to a considerable distance 0111 the pi e and is not wholly counterbalanced by t e gooseneck at the upper end of the spout. The bearing when complete is enclosed by a flaring cap 32, Fig. 10, which is lowered over the ring 29 and is large enough to embrace the upper end 33 of the standard, thus largely protecting the bearing from dirt and moisture.

For the purpose of causing a more or less automatic action of the stand-pipe tending to swing the spout back into a position parallel with the tracks after the filhng of the locomotive-tankhas been completed a cam device is provided, as more particularly shown in Figs. 1 and 12. This device includes a stationary oval cam 35 on the lower end of the standard 4, within the pit and above the frostfioor p,and a cam-roller 36,adapted to travel on the outer periphery of said cam. The roller 36 is herein shown as mounted between the ends of a lever 37, of which one end is pivoted at 38 to a yoke 39, that is clamped rigidly around the stand-pipe. A heavy spring 40 is stretched between the other end 41 of the le ver 37 and the opposite end 42 of the yoke 39, and its action serves to force the roller 36 against the periphery of the cam 35 with considerable force. This tends to cause the roller 36 to ride down the cam toward least diameter of the latter and reacts, through the lever 37 and yoke 39, to swing the stand-pipe around parallel to the tracks.

At its points of greatest diameter the cam 35 is provided with concentric portions, so that the stand-pipe will have no tendency to rotate while supplying water to the engine, even though the latter may come to a stop when its water-hole is not exactly opposite the stand-pipe. At its points of least diameter, on the other hand, the cam s provided with recesses 43, which serve to receive the roller 36 and tend to hold the stand-pipe against movement when its spout is swung around between the tracks and parallel to the latter. In the position of the parts shown in Fig. 12 the spout may be regarded as occupya position of about forty-five degrees from its two extreme'positions, the roller 36 being ready at this movement to travel down into the adjacent hollow 43 as the spout swings back parallel with the tracks, or to climb the cam in the opposite direction as the spout assumes a position at-right angles to the track, as shown in Fig. 1.

The valve which I havedesigned for my valve 66.

im roved water=column is a quick-opening an .SlOW-ClOSiD valve, so controlled as to prevent any undue shock or Water-hammer, and it is furthermore so constructed as to permit the water remaining in the column after the valve is closed to leak away and revent freezing in the stand-pipe. Sucii a valve may be operated either by hand or by the hydraulic pressure of the water in the main. In its simpler hand-operated form, such asis shown in Fig. 9, it comprises a cylindrical main valve 50, the lower annular edge -51 of which is adapted for contact with an annular valve-seat 52. This valve-seat is formed at the outer upper end of a U-shaped discharge pipe or section 53 of the valve, the other end of which is formed with a stuflingbox 54, that receives the lower end of the stand-pipe 1.

Surrounding the valve-seat 52 and inclosing the lower end of the mam valve is an inlet-chamber 55, having lateral extensions 56, which are continued along and around the U-shaped pipe 53 to a flanged inlet end 57, v

where connection is made w1th the main that supplies water to the valve and stand-pi e. In closing the upper part of the main va ve 50 is a housing 58, having at the center of its top a stufiing-box 59, throughwhich the operating-stem 60 of the valve is extended to connect with the lever 18. The main valve 50 passes from this housing down into the chamber 55, through a close-fitting opening which will ordinarily be made water-tight by a hydraulic packing 61. Furthermore, the housing is provided at about midway of its height with an inwardlyrojecting annular flange 62, which fits close y around the main valve and 'forms'an approximately water.- tight connection therewith, although the absolute prevention of leaka e at this ,point is unnecessary and no speciaI acking need be provided. This flange 62 ivides the interior of the housing into an upper or cushioning chamber 63 and a lower leakage-chamber 64. Of these the former or cushioning-chamber 63 is connectedwith the discharge-pipe 53, leading to the stand-pipe by a b pass 65, the flow through which is contro led by a The lower or leakage chamber 64, on the other hand, is provided with an outletpipe 67, which may be conveniently controlled by a pet-cock 68.

In operation the stem 60 of the valve is drawn up when the hand-lever 13 is actuated .1

to lift the rods 15 and lever 18. This drawing up of the stem 60 raises the main valve from its seat and admits water from the inlet-

channels

55 and 56 to the U-shaped discharge-pipe 53, and thence through the stand-pipe and spout to the tank of the engme. be very rapid, the water in the upper or cushioning chamber of the housing 58 is allowed 'to escape freely, while the main valve 50 is TDD I Io

To permit this opening movement to moving up, principally through an outletopening 0, provided in the top of the main valve 50 and normally closed by a springpressed valve-plate O, (conveniently an ordinary rubber pump-valve.)

The closing of the valve is accomplished by swinging the main lever 13 back to its normal position on the latticed framework 7 and by thus depressing the rods 15 and lever 18 and forcing down the valve-stem 60. During this movement the pump-valve O is closed and largely prevents the entrance of water to the cushioning-space above the piston through the opening 0, and there is a consequent tendency for a vacuum to form in this cushioningchamber and for the descent of the valve to be therebyretarded. This retardation, however, is modified, as herein shown, by the bypass 65 and by a series of apertures 69, providedin the cylindric wall of the main valve and through which a limited flow of water may take place during the beginning and greater portion of the valve movement. These apertures are arranged in a row some what inclined from the horizontal and are .also shown in this instance'as' made of increasing diameter from the uppermost to thelowermost hole of the series. When the valveis in its uppermost position, the entire series only channel for admitting water behind the main valve. The final closing movement of the valve is then completely controlled by the How of water through the by-pass, and this may be regulated by adjusting the valve 66. Said by-pass and valve therefore afiord an exterior and readily-accessible means of adjusting the valve movement as desired or as may be necessary to prevent undue shock or water-hammer. After the valve has thus closed the water remaining within the standpipe gradually leaks away through the outlet-pipe 67 and petcock 68, which latter alwa s will be left at least partially open, this lea age continuing through the apertures 69 and leakage-chamber 64 until the level of the water within the stand-pipe is lowered to the level of the outlet 67, which is a sufficient distance below the frost-floor to obviate all danger of the stand-pipes freezing up during its periods of operation.

In the more highly developed form of valve (shown in detail in Figs. 3 to 8) the hydraulic pressure of the water from the main is relied upon to operate the valve; but the movement valve is free to reciprocate.

of the valve is controlled much the same and located, as before described, in connection with the handoperated valve. This main valve is connected byatubular valve-rod 7 6 with an actuatingpiston 77, which is mounted to reciprocate vertically within a pressure-cylinder78, conveniently located in i the upper part of the valve-housing. At its upper end the tubular piston-rod 76 passes out of the top of the housing through a stufiing-box or hydraulic packing 79 and is itself provided with a stufiingbox or hydraulic packing 80, through which the operating- A pistonvalve 81 fits within the tubular piston-rod 76 and is secured therein "to the valve-stem 60,

.which latter is also made tubular and closed at its upper end, its lower end being left open and; projecting down through a hydraulic packing 82 intothe discharge-section 53 of the valve. r

The valve 81 is essentially a Dvalve'i. a, it is provided with upper and lower bearing surfaces or rings 83 and 84', between which is an annular exhaust-passage 85, that communicates with theinterior of the valve-stem 60 through one or more ports 85*. Opening through the tubular piston-rod 76 at points above and below the piston 77 are

ports

86 and 87, placed so close together that only one set of said ports at a time can be uncovered by the valve-piston 81.- These ports admit water to the cylinder 78 either above or below the piston 77, as may be desired, and according to the position occupied by the valvestem 60. This Water enters from the main through a radial channel 88 in the main valve 75 and passes thence up through the tubular piston-rod 76 and (in order to reach the upper ports 86) through vertical channels 89 in the valve 81. I

The position occupied by the parts when the main valve is closed and the apparatus is at rest is indicated in Fig. 3.

In Fig. 8 the valve-stem 60 is shown as drawn up so; as to admit Water to the lower end of the cylinder 78 through the ports 87, the lifting movement of the main valve 75 being now just about to commence.

In Fig. 4 the upward movement of the main- I valve has 'just been completed, the valvestem 60 and inner valve-piston 81 being. still manually-operated valve shown in Fig. 9. The interior of the housing 58 around the main valve 75 is divided by a similar inwardly-projecting flange 62 into an upper cushioning-chamber 63 and a lower leakagechamber 64, the former being connected with the discharge-pipe 56 of the valve-casing by a by-pass 65, controlled by a valve 66, and the cylindric wall of the valve is provided with a similar inclined row of apertures 69 of varying sizes which open into the cushioning chamber 63 above the valve 62, or into the position occupied by the valve. At their inner ends these apertures 69 in this instance open into a segmental port 92, which is cored in the cylindric wall of the main valve 75 and leads down and out beneath the transverse wall 93 thereof, said apertures and port thus constituting channels of communication be-- tween the opposite sides of the main valve. A large outlet through the main valve is also herein shown as provided in an opening 0, located inthe transverse wall 93 of the valve,

and controlled by a spring pressed valveplate 0, (also conveniently an ordinary pumpvalve,) which permits water to flow out of the cushoning-chamber through the opening 0, but prevents it from entering the chamber at this point. With this construction when the'valve-stem and piston-valve 81 are drawn up water is admitted from the main to the lower end of the cylinder 78 through the radial channel 88, tubular piston-rod 76, and ports 87, Fig. 8. This forces up the piston 77 and causes the main valve to be lifted with the piston, by reason of their being rigidly connected by the tubular piston-rod 76. During this opening movement of the main valve, the water in the cushioning-chamber 63 readily escapes, rincipally through the outlet-opening 0', and the valve consequently opens very quickly, and finally assumes the position shown in Fig. 4. Y

c To reverse the operation the valve-stem 60 and piston 81 are depressed and water is admitted to the upper end of the cylinder 78 through the radial channel 88, tubular pistonrod 76, vertical channels 89 and ports 86, and the piston 77 is forced down, carrying with it the main valve 75. The initial closing movement takes places rapidly and freely, owing I to the large area of communication with the cushioning-chamber afforded by the several holes 69, by which water from beneath the valve is permitted to rush into said chamber and relieve the tendencyfor a vacuum to form behind the valve. This area, however, raduall decreases as the holes 69 are cut off by the ange 62 until just before the valve comes in contact with its seat. The only remaining channel through which water .may

enter the space behind the valve 75 is the bypass 65. So that by adjusting the capacityof this by-pa'ss by meansof. the valve 66 the final closing movement of the main valve 75 may point of t be controlled to occur as gently as possible and in the same manner as in the case of the hand-operated valve.

In both forms of this improved valve mechanism a curved guide-plate will desirably be provided to direct the water smoothl into '53 beneath.

In the form of valve shown in Figs. 3 to 8,

however, such a guidelate G is permanently secured to the lower side of the valve75 and moves With'it. A central aperture is also provided in this plate G for the hollow valvestem 60 to reciprocate freely through'and to thereb discharge the water exhausted from the cy inder 78 into the discharge-pipe 53 in either the closing or opening movement of the main valveand its actuating-piston. f
