SPECIFICATION forming part of Letters Patent No. 699,801, dated May 13, 1902.
Application iilcd August 161 1901; Serial No. 72,298. (No model.)
T0 all whom, it may concern:
Be it known that I, EDMOND MARTIN, a citizen of the United States, residing at Potsdam, in the county of St. Lawrence and State of New York, have invented a new and useful Spray-Nozzle, of which the following is a speciication.
This invention relates to nozzles, and has for its object to provide an improved device of this character particularly designed for use as a lawn-sprinkler and is arranged to conveniently secure a plurality of adjustments for varying the character of the dischargeas, for instance, to secure a line spray and also a broad projected sheet of water in the nature of a fountain.
It is, furthermore, designed to provide for convenientlycontrollin g the direction of discharge, so that the water may be discharged laterally in any direction and cut off in the opposite direction, which feature of the invention is designed to obviate the wetting of a walk or the side of a building by directing the discharge of water laterally away from such parts, so as to effectually sprinkle the adjacent portions ofthe ground. p
With these and other objects in view the present invention consists in the combina# tion and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularlyy pointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings, Figure l is a perspective View illustrating the present form of nozzle applied as a lawn-sprinkler. Fig. 2 is a detail perspective view of a nozzle embodying the present invention. Fig. 3 is a central longitudinal sectional View thereof. Fig. 4 is a similar view showing the adjustable cutoff sleeve in position to close one side of the nozzle. Fig. 5 is a detail perspective viewof the adjustable cut-oif sleeve.
Like numerals of reference designate corresponding parts in all of the figures of the drawings.
Upon reference to the accompanying drawings it will be seen that the present device embodies an open-ended tubular body l,which has one end provided with an enlarged interiorly-screW-threaded portion 2 to form a coupling for connection with a hose or other water-pipe in the common or ordinary manner. Within the interior of this' body there is provided a transverse diametric cross-bar or bridge 4, which is comparatively narrow, so as not to materially obstruct the passage of water through the nozzle and having a screw-threaded opening formed at the center of the bar designed for the adjustable reception of the screw-threaded stem 5 of the baffle or sprayer plate 6, that is located outwardly from what will be termed the outer end of the nozzle and of greater diameter than the latter, so that it may be set tightly against the adjacent end of thebody, and thereby effeetually close the nozzle. For convenience in adjusting this plate there is provided one or more projections or finger-pieces 7 upon the outer side of the plate, whereby the latter may be rotated to feed the stem 5 in an endwise direction through the opening in the supporting cross-bar 4. The inner face of the sprayer-plate is provided with a concentric groove or seat 8, which lies outwardly of the body l.
It will loe understood that when the plate 6 is set snugly against the adjacent end of the tubular body the latter is closed against the` passage of water, and by rotating the plate itmay be adjusted or extended outwardly from the body, and thereby provide a marginal opening between the latter and the plate and for the lateral discharge of Water radially in all directions. By varying the distance between the sprayer-plate and the tubular body either a very line spray discharge or a comparatively broad discharge may be secured, the latter discharge being in the nature of fountain.
Upon the exterior of the tubular body there is provided a rotatable and endwise slidable adjustingsleeve 9, which is slightly shorter than the body, and is limited in one direction in its endwise movement by the marginal stop-shoulder 10, formed by the enlarged coupling portion of the body, and in its opposite direction by the marginal edge portion of the sprayer-plate 6, that projects laterally beyond the body.` A portion of tho outer IOO edge of the sleeve is cut away so as to provide the substantially semitubular ange portion 1l, that is designed to be projected beyond the outer end of the tubular body and into the marginal groove or seat inthe inner face of the sprayer-plate, as clearly indicated in Fig. 4 of the drawings, thereby closing onehalf of theV marginal opening between the sprayer-plate and the nozzle-body, While the opposite half of said opening is unobstructed to permit of the free lateral discharge of Water. It will be understood that the interior of the adjustable sleeve and the exterior of the body are smooth and have a comparatively snug frictional engagement, so that the sleeve is retained thereby at any desired adjustment. A frictional engagement of this character is preferable, as it permits of a quick adjustment of the sleeve and is sufficient to hold the latter, as there is no strain thereon. For convenience in adjusting the sleeve the exterior of the latter is roughened to afford a finger-grasp portion, preferably by providing the same with a plurality of marginal grooves l2.
By means of the adjustable sleeve 9, which is constructed to cut off the lateral discharge inl one direction, While permitting of the discharge in the opposite direction, the nozzle or sprinkler may be located adjacent toa walk or building, with the cut-off-flange portion 11 disposed toward the walk or building to cut olf the discharge of water in that direction,thereby obviating wetting of the walk or building while the water is being directed to sprinkle portions of the ground adjacent to the walk or building.
It will be understood that this form of nozzle directs the water laterally and is therefore designed for application to a stiff upright pipe-section, as indicated in Fig. l of the drawings, rather than to an ordinary flexible hose. Should the nozzle be applied to a hose, it will be necessary to -employ a suitable holder for supporting the nozzle in an upright position.
By reference to the sectional views 3 and 4 it will be observed that the cut-0E flange 11 when received within the marginal seat or groove 8 in the sprayer-plate 6 forms a watertight joint therewith, and by reason of the slidable mounting of this sleeve the latter may be simultaneously moved inwardly with the sprayer-plate when the latter is rotated to move the same inwardly, whereby the sleeve does not interfere with the inward adjustment of the sprayer device and also does not require to be adjusted independently thereof.
What I claim is- 1. In a nozzle, the combination with a tubular body, and a sprayer device at one end thereof, of a cut-od sleeve mounted upon the body in cooperative relation to the sprayer device, and having means for directing the discharge laterally at one side only of the sleeve, also having an endwise-slidable adjustment and a rotatable adjustment, the two adj ustments being independent of each other.
