Letters Pa nt- Patented June 27, 1911. 1910. Serial No. 563,073.

fl'o all whom it may concern: I

Be it known that I, GEORGE L. GLASER,

- a citizen of the United'states, and a resident agricultural, botanical and horticultural purposes, also for the equal and economical distribution of water'and other liquids for fire extinguishment, and for other-purposes where the spray may be advantageously used or applied. To this end the nozzle is constructed so that the liquid will 'issue through the spraying tip only, which tip is revolubly mounted and discharges at such an angle to its axis of revolution as to give the maximum range of distribution, and is suitably driven during the period of discharge, preferably by a motor actuated by the liquid preparatory to the ejectment of: the latter at the tip, whereby the liquid at? the instant of its issuance from the tip is hurled from its natural linear direction into a curved path, and is disintegrated into drops or spray, the nature of either being determined by the speed, length and diameter of the tip, which speed is controlled by the character of the motor, the length of the tip and the head or pressure of the water.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts, in all the views. I

Figure 1 is a central longitudinal section through a nozzle constructed in accordance with my invention; Fig. 2 is a cross-section of the same, on the line yg of Fig, Llooking in the direction of the arrow 2', Fig. 3 is a section of the nozzle on the same line, looking in the direction of the arrow 3, and Fig. 4 is a cross-section of the nozzle. on the line m-w of Fig. l, lookingvin the direction of the arrow 4.

In the embodiment of my invention as j illustrated, the nozzle comprises a body pol ring 12. v

The outer section 5 of the nozzle is shown to beprovided with an internally-threaded hose or pipe coupling 13, from which extends through the opposite end of this section, a passage 14: for the solution, this passage in some instances being of helical form, as shown. -The outer section 6 of the nozzle body is enlarged at itsinner end and counterbored to form a shoulder 15, on which the diaphragm 11 seats, the diaphragm being slut-ably keyed orheld against revolution when 1n place, by any suitable means, such as a projection 16 formed thereon and extending into a recess 17 formed in the face of the shoulder. 'Both sections of the body of the nozzle are? preferably expanded toward the center or their point of union, with the inner section provided with an external flange l8'adapted to neatly fit within the counterbored portion of the outer section 6, and presenting a shoulder against which the retaining ring 12 is adapted to bear and bind the two sections firmly together and form therebetwe'en a fluid-tight joint, the retaining ring, as shown, snugly fitting about the portion of the section 5 adjacent to the flange 18, and threaded within'the enlarged counterbored portion of the outer section 6. The outer section 6 ofthe nozzle body has an extended neck 19, in which the tubular stem 7 closely-fits, and is counterbored at the base of the neck to form a suitable recess to receive the roller bearing .10, the latter, as shown, b ing interposed -between the shoulder of the body thus formed and the shell of the motor-9, this shell being integral or otherwise rigid with the tubular stem 7, and conforming to the taper of the section 6 and extending to the diaphragm 11, the shell of the motor being of a size to leave a relatively small space between it and the inner wall of the body section 6 of the nozzle when the shell is firmly seated on the roller bearing, so that the entire thrust of controlling diaphragm 11 and a retaining the motor will be borne. by this bearing, and, l

as a consequence, the friction reduced to a minimum. The motor has centrally of the shell 9, a stem 20, which terminates short of the tubular stem 7, and is rigidly connected to the shell by a number-of helical actuating, blades or vanes 21, these blades being ofany suitable number and forming in connection with each other and with the stem and shell a discharge tip ,8, a motor 9, a bearing 10., a

of the motor, a series ofhelical passages lot ' liquid.

for the solution, all discharging at the pointy of the stem 20 into the tubular stem 7.

The diaphragm 11 is provided at a .point dver the actuating vanes 21 with an opening 22 for the passage ofthe solution, with which the discharge end of the passage it is adapted to lle brought into register, the passage 14 when brought over the opening, directing the flow of the solution against the vanes of the motor approximatelynormal thereto. By loosening the retaining ring slightly, thebody-section 5 of the nozzle may be revolved relatively to the outer section 6, and the diaphragm 11, to cut down or adjust the flow, or entirely out it oif if desired.

The discharge tip 8 of the nozzle forms a continuation of the tubular stem 7, and has its discharge end arranged at an angle of approximately 45 to the, axis of revolu tion, this angle of discharge ordinarily giving the maximum range of distribution and causes the thorough breaking up ofithe other sections can be completely cut. off "without necessitating special valves for this purpose. The water or other solution as it passes through the motor causes the latter, together with the tubular stem and tip, to

be 'revolved at a speed depending on the pressure and the relative sizes of .motor, nozzle tip, etc., and then passes through the tubular stem and the tip 8, the solution as it issues from the latter being broken up by l the rotary action, as before described, and

projected over an area having a radius equal to the range of e ectinent. the same as 1f the nozzle were stationary.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
