ROBERT B. GREENW'AY, OF SAN BERNARDINO, CALIFORNIA.

STAND-PIPE.

Application filed February 2, 1914.

To all whom it may concern:

Be it known that 1, ROBERT B. GREENWAY, a citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State of California, have incharging oil or water into the tender of a locomotive.

The object of my invention is to provide a novel stand pipe, which is not liable to be pulled down by an engine, the tender of which is being filled, being inadvertently moved.

Another object of my invention is to provide a stand pipe in which the delivery pipe is automatically raised and is required to be held down during the discharge of oil or water, to prevent the material discharged from running over the tender due to the carelessness of the operator.

Another object of my invention is to provide automatically operating means for 0011- trolling the flow of the oil or water through the stand pipe.

Uther objects of my invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention, Figure 1 is a side elevation of my improved stand pipe, the delivery spout being shown in the raised position. Fig. 2

is a central vertical sectional view of the upper end of the stand pipe and of the inner end of the delivery spout. Fig. 3 is a plan view of my improved stand pipe. Fig. 1 is an enlarged horizontal sectional view on the line -1 of Fig. 1, some of the parts being broken away. Fig. is an enlarged cross section on the line 5-5 ofFig. 1. Fig. 6 is a vertical section on the line 6-6 of Fig. 41. Fig. 7 is a fragmental elevation oit'the sliding collar and parts connected therewith.

tical axis and which discharges into a laterally extending delivery spout 8, which is pivoted to two cars 1 with which the head 2 is provided.

The vertical pipe section 1 is provided with a valve casing 5 in which is mounted an ordinary slidable cut-ofl valve having a stem 6, which extends through and is pivcted in-a slot 7 provided in one end of one arm of a bell crank lever 8, which is pivoted at its angle to a bracket 9 having its inner end bifurcated and encircling, and clamped to the pipe section 1 by a bolt 10. The other arm of the bell crank lever 8 is pivoted to a connecting rod 11, which in turn is pivoted to one end of a lever 12, which is pivoted to a bracket 13 having a bifurcated end encircling the pipe section 1 and clamped thereto by a bolt 14. The other end of the lever 12 is bifurcated, the arms of said bifurcated end having secured respectively therein two diamatrically opposite pins 15, which are located in a peripheral groove 16 of a collar 17 which is vertically slidable on'the pipe section 1. The collar 17 is provided with two diametrically opposite arms 18, the ends of which are respectively pivoted in slots 19 provided respectively in two arms 20 provided at one end of a lever 21, which is pivoted to a bracket 22 secured to the head 2. The other end of the lever 21 is provided with a slot 23 through which extends a bolt 24, which also extends through a slot 25 provided in one end of a horizontal piston rod 26.

The piston rod 26 extends through central holes provided in the heads 27 and 28 ofa cylinder 29 which is carried on the upper side ofthe spent 3.- In the cylinder 29 is reciprocatively'mounted a piston 30 which is secured to the piston rod 26.

For retracting the piston 80 to the position shown in Fig. 1, the outer end of the piston rod 26, outside thecylinder 29, has secured to it a horizontal bar 31 provided adjacent to its opposite ends with holes in which are mounted longitudinally adjustable screw-threaded bolts 32, on one set of ends of which ,are respectively mounted wing nuts 33, and the opposite set of ends of which are respectively secured to one set" of ends of two longitudinal coil springs 34,

the "opposite set of ends of which are respectively secured to two bolts 35. Said bolts 35 extend through holes provided therefor in a transverse bar 36 secured to the adjacent head 27 of the cylinder 29. Respectively mounted on the bolts 35 and bearing against the bar 36 are wing nuts 37.

For forcing the piston 30 outwardly, I provide a conductor comprising the following described parts: A pipe 38, which has one end connected to a tank, not shown, adapted to contain fluid, such as air, imder pressure, has its other end connected to one end of a flexible pipe 39, the opposite end of which is connected to one end of a pipe 40, the other end of which is fitted in a peripheral hole provided in a valve casing 41, in which is rotatably mounted a valve 42, provided therethrough with a transverse passage 43, which is adapted to register with the opening, in which is mounted the pipe 40 and with a peripheral opening, in which is fitted one end of a pipe 44, the other end of which is mounted in a peripheral hole extending through the side of the cylinder 29 adjacent to the head 27 and at the inner end of the piston 30, as shown in Fig. 4.

A pipe 46 has one end extending through the cylinder head 27 and has its other end mounted in an opening in the casing 41 which is adapted to register with a transverse passage 47 provided in the valve 42, said passage being adapted to register at the same time with a peripheral outlet 48 extending through the casing 41 and communicating with the atmosphere. The valve 42 is provided with a peripheral shoulder 49 which is normally held against an annular inner seat in the wall of the casing 41 by a coil spring 50 which bears at one end against the adjacent end of said valve, and at its other end bears against a circular screwthreaded head 51 fitted in the adjacent internally screw-threaded end of the casing 41. The passages 43 and 47 as shown in Fig. 6, are disposed at angles to each other, and are arranged, when the valve 42 is oscillated, to alternately communicate with the pipes 40-44 and the pipe 46 and outlet 48.

For oscillating the valve 42, the following described mechanism is provided: One end of the valve 42 is provided with an axial stem 52, which extends through an axial hole provided in the head 51 and which, outside of said head, has secured to it a crank 53 provided at its outer end with a slot 54 through which extends a screw 55, which is secured to a rectangular frame 56 which embraces the spout 3 and is slidably mounted in vertical guides 57, with which opposite sides of the spout 3 is provided. A coil spring 58 has its upper end bearing against the under side of the spout 3, and has its lower end bearing against the frame 56, Fig. 5, whereby the valve 42 is normally swung to the position shown in Fig. 4, in which position the passage 43 is closed and the passage 47 communicates with the atmosphere and wth the exhaust pipe 46.

A spring bar 58 has one end secured by two collars 59 to the underside of the spout The free end of the spring bar 58 is adapted, when the spout 3 is swung downwardly at its outer end, to strike against a. locomotive tender 60 and to be forced thereby against the lower end of the frame 56, which will be forced upwardly against the pressure of the spring 58', so as to disconnect the passage 47 from the pipe 46 and to connect the passage 43 with the pipes 40 and 44. The outer end of the spout 3 is thus forced downwardly by an operator standing on the tender 60. lWhen the spout has been thus depressed, the fluid under pressure will pass by the pipes 38, 39 and 40, the passage 43, and the pipe 44 into the cylinder 29, and

will force the piston 30, together with the piston rod 26 to the right, as viewed in Fig. 4, against the tension of the retracting springs 34. This movement of the piston rod 26 will cause the valve in the valve casing 5 to be openedthrough the intermediacy of the lever 21, collar 17, pins 15, lever 12,

connecting rod 11, bell crank lever S, and valve stem 6, thereby permlttmg water or oil, as the case may be, to pass through the pipe section 1 and spout 3 into the tender 60.

As soon as the weight of the operator is removed from the spout 3, it will at once be swung upwardly to the normal position shown in Fig. 1 by means of a coil spring 61, one end of which is connected to a bolt 62, which is secured to a clamp 63, which is secured to the spout 3. The other end of the spring 61 is secured to a bolt 64 which extends through a vertical standard 65 disposed at the left of the pipe section 1 as viewed in Fig. 1. As soon as the spout 3 rises, the free end of the spring bar 58 moves downwardly, thereby permitting the spring 58 to force downwardly the frame 56, theretion between the passage 47 and the pipe 46 and outlet 48, as shown in Fig. 4. When the parts are in this position, the springs 34 will retract the piston 30 to the position shown in Fig. 4, the air in the cylinder 29 at the left of the piston escaping to the atmosphere by way of the pipe 46 and passage 47. The piston rod 26 will thus force the valve in the casing 5 to the closed position through the iutermediacy of the mechanism already described.

For the purpose of lubricating. the interior of the cylinder 29, it may have secured to its upper side a valved-inlet fitting 66. A. counterweight 67 may be mounted upon a laterally extending arm 68 secured to the head 2 at the side opposite to that to which is connected the spout 3. When the spout 3 is horizontally revolved with the head 2, the collar 17 will be turned by the lever 21, the pins 15 traveling in the annular groove 16 of said collar.

From the foregoing description, it will be understood that water or oil will flow through the stand pipe and spout only during the time that the operators weight holds the outer end of the spout 3 sufficiently depressed so that the spring .bar 58; will be forced by the tender 60 to a position in which the frame 56 will be held in its uppermost position. As soon as the weight of the operator is removed from the spout, the coil spring 61 will swing the spout upwardly, thereby freeing the spring bar, 58 from the frame 56 which will be forced downwardly by the spring 58 so as to disconnect the passage 43 from the pipe 40, thereby cutting off the supply of compressed fluid from the cylinder 29 and permitting the springs 34 to retract the piston rod 26 so asto shut ofl the flow through the stand pipe.
