SPRAYING=NOZZLE.

SPECIFICATION forming part of Letters Patent No. 511,729, dated December 26, 1893.

Application filed April '7, 1893. Serial No. 469,454. (No m del.)

To all whom it may concern:

Be it known that I, WILLIAM L. DEMING, a citizen of the United States, residing at Salem, in the county of Oolumbiana and State of Ohio, have invented certain new and useful Improvements in Spraying-Nozzles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to apparatus for spraying. trees, plants, &c., for the purposes of treating them with the various wellknown insecticides or disinfectants, and has for its object the production of a cheap, simple, and effective nozzle designed, arranged and adapted to apply such solutions to tender as well as hardy shrubbery, at the same time providing for a wide range of distribution of the spraying liquid thus used.

The invention will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawings which form part of this specification, and in which like letters indicate like parts wherever employed, Figure 1, is a side elevation, and Fig. 2, a longitudinal central section of my improved nozzle, detached.

Reference being had to the drawings and letters thereon, A, indicates the body of my invention, preferably cast from brass as also are the balance of the parts, and provided with a longitudinal compression chamber 13, closed at one extremity by an end wall co perforated as at b, for a purpose that will hereinafter appear.

To the side of body A, and integral therewith, is an enlargement or web of metal O terminating in a projecting screw-threaded coupling 0, for connection with a hose or force pump; while said web 0 is intersected by an oblique channel D,connecting and establishing communicai ion between the coupling 0 and chamber B. Body A, at its opposite end is provided with an external screw-thread d, adapted to receive a corresponding thread 6 on the inner wall of cap E, said cap serving as a covering for chamber B, and being provided with a flaring orifice F in its outer face, and a similar one fin its opposite face, the two combining to constitute a discharge port as shown in Fig. 2.

Resting in aperture b, and within chamber B, is located a longitudinally reciprocating and axially rotatable spraying and cleansing piston, consisting of a shaft or stem G, provided with a push button g at its outer extremity, its opposite end being conical as at H. At the base of this cone, is formed an integral collar or enlargement h equal in its diameter to that of channel B, and having cut in its periphery a spiral groove I, forming the only source of outlet for the spraying liquid; while at a point in chamber B, on the opposite side of inlet channel D, is arranged a second collar 2', similar to that marked it with the exception only of the peripheral groove, and between this latter collar and end wall a is interposed a packing ring J of rubber or other suitable material.

The operation of this improved nozzle is as follows: A suitable spraying mixture having been introduced under pressure through channel D, to chamber B, exerts its force upon the walls of said chamber and upon the inner surfaces of the collars h, and 'i, but with unlike effect, inasmuch as, the peripheral screw I affords a vent or outlet through the former thus reducing the pressure in that direction, while its full force and effect are received by the latter, tending to keep it normally seated as shown by Fig. 2. The spiral channel I, through which the liquid is then forced serves to impart thereto a regular, rapid revolving motion in which condition it is ejected from the double orificesf, F, by meeting the edges of which it is further disintegrated and reduced to fine spray. Should the discharge nozzles become clogged by continuous use of heavy solutions or those which are not clear, such for instance as mixtures embodying lime; it is only necessary to elevate piston G by pressure applied to button g, by which movement cone II will be caused to enter the discharge orifices in cap E for the purpose of cleansing them of sediment or foreign matter.

Having thus described my invention, what I claim is- 1, In a spraying nozzle, the combination with a main compression chamber having a side inlet or supply channel, and a reciproeating rotatable piston located in said chamher having a spiral. outlet in its periphery, substantially as described.

ICO

spirally grooved head with its opposite end v protruding from said chamber, a conical distal end on said rod registering with the discharge orifice, and a disk located near the opposite end of the rod, substantially as described.

In testimony whereof I subscribe my signature in presence of two Witnesses.

WILLIAM L. DEMING.
