SPECIFICATION forming part of Letters Patent No. 688,688, dated December 10, 1901.

Original application filed January 23, 1901, Serial No. 44,362. Divided and this application filed August 3, 1901. Serial No. 70,826. (No model.)

T h m it may concern: The novelty of the invention lies mainly in 50 Be it known that I, WALTER H. PUMPHREY, utilizing the outer end of the ordinary syr a citizen of the United States of America, and inge-pipe and adapting it to coact with a bulba resident of New York, in the county and like sleeve in the production of a whirling- State of New York, haveinvented certain new spray discharge.

The sleeve may be of uniproduction of a syringe in which metallic form or varying diameter, its function being 40 parts are entirely dispensed with; second, in to provide a curved surface or wall against which the spraying device is so relatively arwhich the jet or jets of liquid flatten and 0 ranged with respect to the discharge-orifice spread when discharged from the syringe that in use contact therewith is rendered imtube. possible; third, in which separable parts are 3 3, &c., represent the outlets of the syringe- 45 employed and being readily accessible are tube, which are disposed tangentially to the convenient for cleansing, &c., and, finally, in bore thereof and of which there may be any which the spraying device does not offer the suitable number, the same being formed by slightest obstruction to the free entrance of one or more tubular branches 3 &c. the liquid when the syringe is being charged. The liquid in passing through these tubular den deflection from a straight-away course the liquid is given a whirl and passes spirally through the bulb-like sleeve-section. In being thus acted upon the liquid is converted into whirling spray, which in its discharge assumes a globular form.

Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is-

In a syringe, the combination of a jet-tube provided adjacent to its outer end with one ing the end of the tube and its branched outlets and providing a curved wall against which the liquid is directed.
