orrm c GEORGE A; WEIDLTCH, E BATTLE CREEK, MICHIGAN, AS-SIGNOR TO A-IB STOVE i COMPANY, OF BATTLE CREEK, MICHIGAN.
To all whom it may concern:
, Be it known that I, GEORGE A. WEIDLICH,
a citizen of the United States, residing at Battle Creek, Michigan, have invented ce' rtain new .and useful Improvements n Spray-Nozzles, of which the following 15 a specification.
This invention relates to a spray nozzle.
The Objects of this invention are:
First, to provide a head for a spray nozzle by'means of which any character of spray from a very fine spray to a single jet or stream may be obtained. v j
Second, to provide a nozzle of the kind described, which will not easily. become clogged.
Third, to provide a head for a spray noz: zle which is simple in structure and cheap to manufacture.
Further objects, and objects relating to details and economies of construction and operation will. definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure constituting a preferred em bodiment of my invention is illustrated in the accompanying drawings forming apart of this specification, in which: i
Figure I is a longitudinal section through the center of my improved spray nozzle, showing the cap adjusted to produce a sin gle stream.
Fig. II is a longitudinal transverse sec tion similar to Fig. 1 showing the cap in a position adjusted to produce a spray.
Fig. 111 is an enlarged detail section on a slightly tapered, has an internally threaded enlargement 2 at its larger end, adapted to connect with the threaded nipple of a cou- Specificat ion of Letters Batent. Fermented Jan. 29, 191%.

pling member, and an externally threaded head 3 atits smaller end. The passage through the barrel is uniformly tapered and terminates in an enlargement or chamber within the head constricted by an annular inwardly extending rib a. The end of the head 3 is fiat and provided with two discharge apertures, one of which, 5, is concentric or central therewith, and the other of which, 6, is eccentric thereto, that is, it is disposed to one side of the central hole 5.
An internally threaded cap or tip 7 is threaded for adjustment upon the head 3 and is provided with an inner flat end wall 8 which coiiperates with the flat end of the head 3 to produce a swirl chamber. The cap 7-is provided with an outwardly beveled discharge aperture 9 which is adapted to register with the discharge aperture 6 in the top of a nozzle 12 when the cap 7 is adjusted to its innermost position, whereby the nozzle will discharge. a single solid jet or stream.
\When the cap 7 is rotated to unscrew it from the head 3 the aperture 9 is moved out of register with the aperture 6 and the size of the swirl chamber between the end of the nozzle and the cap is gradually increased, thereby varying the character of the spray produced. As the cap 7 is unscrewed from the head 3, the central discharge opening 5 is uncovered, the portage of the head is increased. A lug 10 depending from the flange 11 of the cap coacts with the pin 12 secured to the head of the nozzle to limit the movement of the cap.
My improved spray nozzle is simple and economical in its parts. It is very efficient in use and may be readily adjusted to vary the character of the spray and further it is not likely to become clogged. I have illustrated an embodiment or adaptation of my improvements such as is suitable for lawn hose or forthe spraying of fruit trees and the like. i
I have not attempted to illustrate or describe certain modifications which might be desirable for other adaptations as I believe the disclosure made will enable those skilled in the art to which my invention. relates to embody or adapt the same as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a spray nozzle, the combination of a body member provided with a head hav- Mill I for the purpose specified. I 2. Ina spray nozzle, the combinatlon of ing-a fiat-face with a centrally disposed discharge orifice and an eccentrically disposed discharge orifice, said body having a passage therethrough terminating in an enlarged head chamber, said head chamber having an annular rib providing a constriction eccentrically disposed discharge orifice of said head when the tip 1s in one position, v
and coacting stops on said head and tip limiting the rotating movement of said tip,
a body member provided With a head having a fiat face with centrally disposed discharge orifice discharge orifice, a tip threaded for adjustment upon said head and having a flat face cooperating with the flat face of said head and provided with a discharge orifice disposed eccentrically and adaptedto register with the eccentrically disposed discharge Copies of this patent may be obtained for five cents each, by addressing the Commissioner and an eccentrically disposed orifice of said head when the tip is in one position, for the purpose specified.
3. In a'spray nozzle, the combination of a body member provided with a centrally disposed discharge orifice and an eccentrr eally disposed discharge orifice, and a tip threaded for adjustment upon said head and having a discharge orifice disposed eccentrically, for the purpose specified.
a. In a nozzle, the combination of a body member provided with a fiat discharge face having a central discharge orifice, and a second discharge orifice disposed at one side thereof, and a cap mounted on said body for rotative and axial adjustment and provided With a discharge orifice disposed at one side of its center and adapted to be brought into register with the second discharge orifice of said body member.
In Witness whereof, I have hereunto set my hand and seal in the presence of two Witnesses.
