WALTER H. PUMPHREY, OF NEW YORK, N. Y.

SYRINGE.

SEEGIFIGATIUN forming part of Letters Patent N 0. 713,017, dated November d, 1902.

Original application filed March 8, 1901, Serial No. 50,301. Divided and this application filed May 9, 1901. Renewed March 22, 1902. Serial No. 100,385. l'lo model...)

To a, whom it may concern.-

Be it known that I, WALTER H. PUMPHREY, a citizen of the United States of America, and a resident of the city of New York, county of New York, State of New York, have invented certain new and useful Improvements in Syringes, of which the following is a specification.

My inventionrelates generally to syringes,.

and more particularly to that class designed to discharge the liquid in the form of a whirl ing spray, the same being a division of my pending application filed March 8, 1901, and serially numbered 50,301.

The object of the invention is to produce a syringe of this character the nozzle of which will be of a form such as can be readily constructed entirely of hard rubber, thereby avoiding the use of metal and the objectionable corrosive action of the liquids thereon.

A further object is to provide for the ready and convenient disengagement of.the parts or members of the nozzle and the exposure of the inner as well as the outer surface thereof, so as to enable the user to thoroughly cleanse the same and prevent the deposit and accumulation of foreign matter.

The novelty of the invention lies in the;

form of the nozzle members and their peculiar relation by which a globular whirling spray discharge is produced without the aid of socalled spraying devices, such as liquid-deflectors, &c., which are ordinarily located in the bore of the nozzle'and tend to obstruct the:-

fiow of liquid and render the charging or fill ing operation tedious and lengthy.

The preferred form embodying my invention is illustrated in the accompanying sheet of drawings, throughout the several views of which like reference-numerals indicate corresponding parts.

Referring to the drawings, Figure l is a view in elevation of a syringe embodying my invention, the outer portion of the pipe and tip being shown in section; and Fig. 2. is a cross-sectional view on the line 5 s In thedrawings, 1 represents the stem of the nozzle, which consists of a straight or other suitable form of tube 2, terminating, preferably, in a daring mouth 3.

T 4 represents a tubular section designed to serve as the nozzle-tip and preferably having theeXt-ernal form of a bulb, the same being arranged in advance of the stem as an extension thereof by being fitted in the flared mouth of the tube. The bulb-shaped tip is designed to receive the liquid from'the tube and for this purpose is provided with requisite openings 5 5, &c., which are preferably tangentially disposed, as is clearly shown in the cross-section, wherein the direction of fiowof the liquid is indicated by arrows. At the outer end the tip is provided with an opening 6, through which the' liquid escapes.

-The tip is threaded into the flared mouth of -'out its length and terminating at its outer end in an enlarged open mouth, and a cham- .beredtip arranged in advance of and having one end removably seated within said enlarged open month, said tip being open'at'its" outer end and having one or more lateral openings at its inner end communicating with the bore of the stem, said openings being arranged so as to discharge liquid from the stein i nwardly into the tip in, a direction tangential to the innercurved wall thereof.

2. In a syringe the combination of the nozzle-stem the outer end of which is cylindrical in cross-section and open, and a chambered oval-shaped tip arranged in advance of and having one end secured to and seated within the open end of the stem, the arrangement being such that an annularchamberis formed between the said tip and stem, said tip being open at its outerend and having one or more lateral openings in its inner end leading from said annular chamber into the tip, said openings being arranged so as to discharge the liquid from the stem inwardly into the tip in a direction tangential to the inner curved wall thereof.

3. In a syringe, the combination of the nozzle-stem, the outer end of which is cylindrical in cross-section and open, and a hollow oval-shaped tip arranged in advance of and having one end inclosed by and removably secured to the open end of the stem, the arrangement being such that the greater part of the tipprojects from the stem and an annular chamberis formed between the stem and tip, and said tip being open at its outer end and provided at its inner end with a plurality of lateral openings leading thereinto from the shaped tip arranged in advance of and having one end threaded into the flared end of the stem, the arrangement being such that an annular chamber is formed between the tip and stem, said tip being open at its outer end and having a plurality of lateral openings in that part inclosed by the stern, said openings leading inwardly into the stem and disposed so as to direct the liquid from the stem into the tip in a direction tangential to the inner curved Wall thereof.

Signed at New York, N. Y., this 7th day of May, 1901.
