STAND-PIPE.

Specification of Letters Patent. f Patented 0G15. 8,4 1918.`

Application led March 15, 1918. Serial No. 222,533.

To all whom t may concern:

Be it known that I, THOMAS E. KELLnrmR,

a citizen of the United States, residing aty My invention relates, more particularly,

to stand pipes which are provided as portions of railway equipment, alongside of the tracks to furnish water to the tenders of locomotives.

rIhe conditions as regards railway rolling stock and the operation of the same, are such, according to present -cday practices, that the stand pipes must be made of such height in order to adapt them to lill the water compartments of locomotive tenders, and avoid obstruction to the rolling stock, that the water valve-operating mechanism provided on the stand pipe usually on a relatively rigid part thereof above the-nozzle of the pipe, is located at such a height as to be very inaccessible to the operator on the tender, especially when the tender is a relatively low one, this condition not only making Vit, diiiicultV for theoperator to actuate the water valve, but rendering the operation thereof oftentimes hazardous.

My primary object is to provide a construction of stand pipe wherein the watervalve operating mechanism, evenk when a relatively high stand pipe is used, is readily accessible Vfor operation by the operator while occupying a comparatively safe place on the tender, to the end of reducing danger to the operator and making his work easier.

Referring to the accompanying drawing,

Figure 1 is a view in side elevation of the. upper end of a stand pipe embodying my improvements. Fig. 2 is a plan View of the outer end of the stand pipe; and Fig. 3, a

broken perspective view of the overhead frame of the stand pipe and a portion of the valve-operating mechanism shown in Fig. 1.

I have chosen to illustrate my invention in connection with a certain construction of stand pipe of a particular type, but without any idea of limiting the use of the invention thereby. shown, the stand pipe is formed ofthe hol; low riser or standard 4, which, in practice, connects with the supply of water which is to bedelivered through the stand pipe and into the tenders, communicationof the pipe In the particular constructionv 4 with the water supply being controlled by means of a valve, not shown, but which is common practice. The upper end of the upright 4 terminates in a laterally-extending portion 5, which is telescoped with a spout section 6, this spout loosely fitting overthe extension 5. "The spout is provided at oppo# site sides at'its rear end with rollers 7, one only of which is shown, journaled thereon, which'travel in curved `guide-ways 8 provided at opposite sides of the spout 6, these guide-ways being rigidly secured to a framework 9, which is connected at one end with a bracket 10 securely fastened to the upper end of the upright 4. The guides 8, which are provided in the same relative position at opposite sides of the spout 6, in combination with the rollers 7., serve as a means for per'-v mitting the spout to be drawn outrelative tothe extension 5 'and'tilted' downwardly( at its forward, discharge, end. Cooperating with the guide-ways 8 and rollers 7, is a flexible element 10, suchas a chain, which is connected at its forward end with the forl ward portion of the spout 6, as indicated'at 11, extends over pulleys 12 and 13 onthe frame 9 and at itsopposite end is counter# weighted in a manner lnot shown, but ink accordance withfcommon practice, this feature of the construction permitting the spout to be raised and lowered at will `and retainedA ered. f This rod is pivotally connected as indicated at 14 with one arm of a bell-crank lrpivoted at 16 to the upright 4, the upper end of this bell-crank being pivotally connected at 17 with a rod 18, which extends generally lengthwise of the frame 9( In practice, it is preferred thatthe parts just described and including the rods 13 and18' and b ell cranlrl, be provided at opposite sides of the stand pipe structure. VThe forward ends of the rods 18 are pivotally connected at kthe pins 23, with the armsv 21 of a yoke 22, the arms of which straddle the forward endof 'the frame 9 and are pivoted medially thereof in an upward and rearward direction in the closed position of the valve, as shown in Fig. 1, and the other represented at 25 and extending substantially horizontally and forwardly into a position Awherein it may be easily grasped bythe operator on the` tender, in the closed position of the valve.` The handle 25 is shown as formed separately from the yoke 22, butrigidly connected therewith at its portion 26 through the medium of rivets 27, the shape of this lever, by preference, being such, as shown, as to cause it to extend at its under surface in contact with the enlarged portion of the adjacent pivot pin 23, in the normal position of the apparatus, the forward end of the handle 25 being preferably laterally offset as represented, it being understood from the foregoing that the handle 25 extends laterally beyond the spout 6, as shown in Fig. 2, thus permitting this handle `to be thrown down alongside the spout without .obstruction.

In the use of the device to open the water valve, the operator standing on the tender, grasps the lever 25 and by pulling downwardly on the latter, rotates the yoke 22 on the pivots 20 in counterclockwise direction in Fig. 1, thus shifting the rods 18 forwardly, rocking the bell-cranks 15 in anticlockwise direction in F ig. 1 and raising the rods 13. In this movement of the member 22, the handle 24e is swung forwardly to a positionv in which it may be f readily grasped by the operator to further move the valve in the same direction, should the handle 25, before the desired position of the valve is reached, have moved out of accessible position to the operator, or should operation by the lever 24 be more convenient.

The-pivots 23 are preferably so disposed relative to the pivots 17 and 2() that they will extend slightly below the planes in which the pivots 17 and 20 extend, when the valve is in closed position. Thus, thev tendency of the parts of the valve-operating mechanism will be to remain in the position shown'in Fig.v 1 and danger of accidental opening of the valve is greatly minimized.

I'Vhile I have illustrated and described av particular construction embodying my invention, I do not wish to ,be understood as intending to limit it thereto, asthe Same may be variously modified and altered without departing from the spirit of my invention, it being my intention to claim my invention as fully and completely as the prior state of the art will permit.

`What I claim as new and desire to secure by Letters Patent is- 1. In a stand pipe, the combination of an upwardly-extending conduit having an extension projecting laterally therefrom and movable up and down at its discharge end, and valve-operating mechanism including hand-operated elements through the medium of which said mechanism is actuated, one of said elements being supported to extend laterally vbeyond said extension to adapt said Last-referred-to element to move up and down alongside said extension, the whole being constructed and arranged to cause the other of said hand-operated elements to be moved into a position for continuing the operation of said mechanism when the latter is moved out of its initial position.

2. In a stand pipe, the combination of an upwardly-extending conduit having an extension projecting laterally therefrom and movable up and down at its discharge end, and valve-operating mechanism including hand-operated levers extending in different directions and through the medium of which said mechanism is actuated, one of said levers being supported to extend laterally beyond said extension to adapt said lastnamed lever to move up and down alongside saidextension, the other of said levers being brought into a position for continuing the `actuation of said mechanism when the latter is moved out of its initial position.

3. In a stand pipe, the combination of an upwardly-extending conduit having an extension projecting laterally therefrom and movable up and down at its discharge end, and valve-operating mechanism including hand-operated levers, one of which extends forwardly and the other rearwardly in the normal position of said mechanism, said forwardly-extending lever being supported to extend laterally beyond said extension to adapt this lever to move up and down alongside said extension, and said rearwardly-extending lever being so positioned as to cause it to move into a position wherein it serves as the medium through which said mechanismeisoperated upon actuating said forwardly-extending lever.

4. In a stand pipe, the combination of an upwardly-extending conduit having an extension projecting laterally therefrom and movable up and down at its discharge end, and valve-operating mechanism including a yoke-member pivoted to extend above said extension, and a forwardly-extending lever and a rearwardly-extending lever connected with said yoke-member and through the medium of which the latter is actuated, said forwardly-extending lever extending later- `ally beyond said extension to adapt said forwardly-extending lever to move up and down alongside said extension.

5. In a stand pipe, the combination of an upwardly-extending conduit having an eX- tension projecting laterally therefrom and movable up and down at its discharge end, a member connected With said conduit eX- tending lengthwise of said extension, and valveoperating mechanism including a yoke-member pivoted at its arms to said rstenamed member and extending above said extension, said yoke-member having a rearwardly-extending handle-section, and a forwardly-extending lever connected With said yoke-member, said lever extending laterally beyond said extension to adapt said lever to move up and down alongside said extension.

6. In a stand pipe, the combination of van upwardly-extending conduit having an extension projecting laterally therefrom and movable up and doWn at its discharge end, and valve-operating mechanism including a rock-member having ak handle-section eX- tending rearwardly and carrying a pivot pin, and a lever connected With said rockmember in the rear of its pivot pin, and bearing intermediate its ends on said pivot pin, said lever extending forwardly and eX- tending laterally beyond said extension to adapt said lever to move up and down alongside the latter.
