Description
Jan. 1, 1946. c. B. FERREL 2,392,085
SPRAY NOZZLE Filed July 29, 1944 I N VEN TOR.
This invention relates to a spray nozzle for use in clinical irrigation.
The object of the present invention is generally to improve and simplify the construction and operation of spray nozzles of the character described, and particularly to provide a spray nozzle having a plurality of discharge orifices which are normally closed, but which automatically open to produce a gentle spray when low pressure is applied to liquid passing through the nozzle, and which opens a central and larger orifice to project a jet of greater force in addition to the spray when higher pressure is applied.
The nozzle is shown by way of illustration in the accompanying drawing, in which:
Fig. 1 is a side elevation of a container, a flexible tube with the nozzle on its end, and a pressure applying bulb intermediate the nozzle and the container;
Fig. 2is an enlarged longitudinal section of the spray nozzle; and
Fig. 3 is an end view of the same.
Referring to the drawing in detail, and particularly Fig. 1, A indicates a container such as a rubber bag or the like which is adapted to contain a liquid such as water mixed with a quantity of antiseptic or other substances to be employed in clinical irrigation. Connected with the lower end of the container or bag is a flexible tube 2 on which is mounted a pressure-applying bulb B, and at the discharge end of the tube is mounted a spray nozzle 0.
The nozzle forms the subject matter of the present application. It is of the self-closing type and is made of rubber or a like resilient material. The nozzle is elongated and tubular in shape, one end being open and the exterior surface being provided with an annular bulge or rib 3 to permit the nozzle to be firmly gripped and secured when inserted in the discharge end of the tube 2.
The discharge end of the nozzle is closed and pointed in shape as shown at 4. A central discharge orifice 5 is formed centrally and at the point, while a plurality of discharge orifices 6 are formed rearwardly of the point and concentric to the orifice 5.
All of the orifices are normally closed due to the contracting or resilient action of the rubber from which the nozzle is formed, but when a. predetermined or low pressure is applied by means of the bulb B, the plural orifices 6 are opened first and a gentle spray action will result, but if greater pressure is applied, the central orifice 5 will open and a central jet of greater force will then be discharged in addition to the spray issuing from the plural orifices.
In order to insure the opening of the multiple 5 orifices first and the central orifice second, when greater pressure is applied, it is essential that the tip or point in which the orifices are formed is fairly resilient and that the annular wall in which the multiple orifices are formed be thinner than 10 the point through which the central orifice projects. By this construction it should be apparent that when low pressure is applied the multiple orifices will open first as the annular wall of the nozzle is thinner at that point and the liquid will accordingly discharge through the multiple orithe central orifice passage will be overcome and a central jet of greater force in addition to the spray issuing from the multiple orifices will result. a
While a bulb is here shown as a means for applying and varying the liquid pressure on the nozzle, it is obvious that any other suitable means may be employed. It is to be further understood that while the nozzle per se has been more or less specifically described and illustrated, various changes may be resorted to within the scope of the appended claim, and the materials and finish of the parts employed may be changed as varying conditions or experience or operation may dictate.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
A nozzle for discharging and spraying liquid substances comprising a tubular member open at one end and pointed and closed at the opposite end, said nozzle being composed of a rubber-like 40 resilient material, said nozzle having a substantially uniform wall thickness but the thickness being greater at the point, a central discharge orifice formed at the point of the nozzle where the wall thickness is the greatest, and a plurality of discharge orifices formed in the nozzle rearwardly of the central orifice and concentric thereto, said plurality orifices being positioned where the wall thickness is substantially uniform and less than the thickness at the point, all of said orifices being normally closed but opening when liquid under pressure is delivered to the nozzle.
