ll Mi Wm HTTORNfH Patented Apr. 10, 1945 FLUID DISCHARGE NOZZLE Bengt E. Folke, Mama'roneck, N; Y., assignor to Nathan Manufacturing Company, New York, N. Y., a corporation of New York Application September 23, 1944, Serial No. 555,439

2 Claims.

The object of my invention is' to provide an improvement in that type of fluid discharge nozzle in which an outlet opening small enough to prevent liquid from running through it when no pressure or very little pressure exists in the discharge line is opened by applying pressure on the fluid to permit its ejection from the nozzle.

Other objects will become apparent in the following specification and in the drawing showing a preferred embodiment of the invention as applied by way of example to a mechanical 'lubricator used to discharge oil in form of a fine jet for the lubrication of gears. I

In the drawing, 4

Fig. l is a general view of an installation of the discharge nozzle in combination with an oil reservoir and a mechanical lubricator for the purpose beforementioned;

Fig. 2 shows an enlarged longitudinal sectionalv 'to a nozzle l5 which is directed to discharge a jet of oil indicated at l6 into gears ll.

Referring to Fig. 2, the discharge nozzle consists of a nipple l8 having an inlet to which pipe I4 is connected and a discharge conduit 20 through it. The nipple at its discharge end is provided with an inner tubular member 2| projecting outwardly. 22 is a, nozzle tip made of a resilient material and is provided with a small discharge orifice 23. The tip has a fiat base where it abuts the discharge end of the nipple l8. Below the outlet orifice 23 the inner part of the tip is enlarged to fit over the outwardly projecting end of the tubular member 2|, leaving a chamber 24 between the end of the member and the outlet orlflce. The outer sides of the tip 22 are tapered at 25. 26 is a nut screwed onto nipple I8 having a tapered extension 21 engaging the tapered sides 25 of the tip 22. The inner tube 2| and the nut 26 serve to confine and support the tip 22 leaving an annular ball shaped portion immediately surrounding the outlet orifice 23 entirely free. The outlet 23 is shown in its normally closed position in Fig. 2.

Fig. 3 shows the nozzle tip as it appears when the outlet 23 is opened by internal pressure of a liquid being forced through it and ejected at high velocity from the nozzle.

While, by way of example, the invention has been applied for use in connection with a mechanical lubricator for the formation of an oil jet, the invention is by no means restricted to such applications. It may be used in a variety of industries in the discharge of gases, liquids, or other fluids.

Many other modifications may be made in the form, proportions and minor details of construction without departing from the principles or sacrificing any of the advantages of the invention as defined in the appended claims.

What I claim as new is:

l. A fluid discharge nozzle comprising a nipple, a tubular projection from the discharge end of said nipple, a resilient tip having an outlet and a chamber adjacent the outlet in communication with said projection, the upstream portion of said tip fitting over said tubular projection and abutting the end of said nipple, and a nut threaded on said nipple, said nut having means thereon for confining between it and the tubular projection said portion of the tip which fits over the tubular projection, leaving an annular portion of the tip immediately surrounding said outlet exposed and free to expand responsive to variations in pressure of the fluid passing through said outlet.

2. A fluid discharge nozzle comprising a nipple, a tubular projection from the discharge end of said nipple, a resilient tip having an outlet and a chamber adjacent the outlet in communication with said projection, the upstream portion of said tip fitting over said tubular projection and abutting the end of said nipple and having tapered outer sdes, and a nut threaded on said n pple, said nut having means thereon for confining between it and the tubular projection by contact with said tapered outer sides said portion of the tip which fits over the tubular projection, leaving an annular portion of the tip immediately surrounding saidoutlet exposed and free to expand responsive to variations in pressure of the fluid passing through said outlet.
