COMBINED NOZZIJE AND DEFLEGTING RING.

Application led November 16, 1923.v Serial No. 675,187.

To all whom t may concern.' l Be it known that I, VENUS I-I. CLARK, a citizen of the United States, residing at'Alliance, in the county of BX Butte and State of Nebraska, have invented certain new and useful Improvements in Combined Nozzles and Deflecting Rings, of which the following is "a specification. Y

This invention relates to a new and improved combined nozzle and deflecting ring for the watering system of railway equipment.

The principal obj ect of the invention is to provide a device of the above character 'adapted t0 be detaclrably carried by the valvev of a watering hose and which comprises a tapered nozzle for insertion into the opening ofl a tank and to secure a substantially tight fit against the walls of the opening and la new and novel deflecting ring or shield adjacent the nozzle to cause any water that might escape the opening of the tank, to be deflected b ack against the same. It is well known in refilling air pressure water tanks that when the entrance port is ope-n, the escaping lair carries considerable water with it, in many instances throwing the same a considerable distance along the Sides of the cars. This also happens after the water hose has been inserted into the tank and while it is being filled. Inl my in# vention, the nozzle is of tapered construction -so as to fit snugly against the wall-s lof the entrance port of the tank and, as above pointed out, I also provide a4 shield behind the nozzle to deflect any escaping water back under or against the cars.

Various other advantages and objects of my invention will become apparent during the continuance of the following description.

In the drawingsf- A d Y Figure 1 is a view in longitudinal section taken through the body of my invention, themain pipe being shown in elevation and slightly brokenaway. In this view the device is also shown in association with t-he entrance port of thetank although this illustration does not, in any way, limit the scope of the invention.

Figure 2 is a view in cross elevation show ing my invention in its preferred lembodiment.

- In describing the:y invention in detail, 1() indicates the body of the nozzle which is in the form of a pipe open at both ends, one

end being exteriorly threaded as at 11vfor the purpose that will presently appear. A cone 12 is mounted on the forward end of pipe 10 and has'the forward or smaller end vterminating just short of the adjacent end of the pipe while its rear or larger end terminates just beyond the intermediate portion of the pipe. The cone is preferably constructed of rubber', although any other suitable or desirable material may be used.

The shield consi-sts of a body portion of substantially the same diameter as the main deflecting portion.A TheV intermediate portion of the outer wall of the body portion of the shield is also cut away and curved as at 15 so that they inner wall of the entire shield will present a smoothly curved surface to whatever it is directed to or against. It will be noted that by reason of the peculiar curvature of the flange 111 of the shield that Water directed there against will be deflected back in the 'substantialdirection from which iticame.

In .Figure 1, I have shown a part of a tank 16 provided with an opening 17 and have shown the nozzle portion of my invention arranged therein as in actual practice. It will be readily seen that if any water es- 'cap'es through the opening 17 it will be directed against the inner curved surface of Vflangela-of thev shield, and directed back against the tank.

Removably mounted on pipe 10, inwardly j of the threads 11 and immediately adjacent the rear end of the rubber cone 12, is the shield or deflecting ring of the invention. This shield or ring, which is preferably of metal, consists of abell-shaped member presenting a raised central supporting portion 13 andra circular deflecting flange 14; the central portion extending almost flush with the outer edge of the flange and being cut away and curved as shown at 15 so that the inner face of the shield will present a smoothly curved surface by which any water impinging thereon will be deflected back substantially in the direction from whence the peculiar shape of the shield on the defleeting side, with the half-circle effect in the center, causes it to drain at all times to the bottom.

In the usual watering system of railway equipment it is customary to supply the toilets and lavatories of a railway car with water from a supply tank 16 located under the car and provided with an entrance port 17 for purposes of refilling. The water in the tank is subjected to a ten-pound air pressure so as to be raised to the proper level and is fed into the lavatory and toilet supply pipe through an outlet pipe from the tank. The tank is further equipped with a threeway valve operating with one move-ment of the lever to shut off the air pressure while at the same time opening the entrance port 17 and the waste pipe or drain of the tank. It is necessary to refill these tanks at frequent intervals as the supply carried at one time is inadequate for the passengers requirements and, as a rule, they are refilled at each division point on the railroad. Under present conditions, the refilling operation is carried out with a great degree of annoyance and physical discomfort bothV on the part of passengers and the trainmen assigned to the task of refilling the tanks. This is due to the fact that when the entrance port 17 is opened by the manipulation ofthe threeeway valve as previously described, the air pres sure released through the waste pipe and entrance port carries with it considerable water which it sometimes throws to a distance from eight to ten feet across the platform wherethe passengers are entering and leaving the trains, causing them to get wet, and, in addition, making the platform slippery and disagreeable to walk on, especiallyT in winter when it collects and freezes. The same disadvantages are present, also, when refilling the gravity or overhead tanks which supply the drinking water. These tanks are each filled through a pipe leading' from the outs-ide of the car to the top of the tank; the outside end of the pipebeing' provided with an entrance port through which the Water is injected.

At present, the tanks are filled by means of an ordinary rubber hose leading from a water line and having a stopcock or valve connected to the outer end. This stopcock has a short length of 37g inch pipe screwed into it to serve as a nozzle but since the entrance ports vary in size from 1% inches to 2 inches in diameter, there is always considerable less of water when refilling the tanks, in addition to what is released by the escaping air pressure.

In adapting the invention to present-used equipment, the 1%: inch pipe above referred to is replaced by my combined nozzle and delecting ring which is screwed into the stopcock by means'of the threads 11 on pipe 10. The tapered formation of the rubber cone 12 enables the device to snugly fit various sizes of entrance ports and when pressed firmly in the entrance port of the air-pressure tank 16 it diverts the escaping air and water through the waste pipe so that it discharges under the car. Any water or air that escapes past the cone during the insertion of the nozzle into the port will strike the shield or ring 13and be defiected back against and under the car. Also, in refilling the gravity tanks, the nozzle is inserted firmly in the entrancel port of the filling pipe, making a tight joint so as to accumulate pressure enough to force the water to the top of the tank; the rubber cone serving as a gasket and the shield as a deflecting ring for defiecting under. the car any water that may escape through the port.

lVhen the device is attached to the rubber hose, as aforementioned', the shield serves also as a guard for supporting the end of the nozzle out of contact with the ground, or mud, or whatever it happens to fall on when the hose is released, thus conforming to the requirements of the different State health and. sanitary boards.
