NOZZLE.

Specification of Letters Eatent.

Application filed April 19, 1909.

Serial No. 490,883.

To all whom it may concern:

Be it known that I, CLiiMENT VACHER, a subject of the King of Great Britain, residing at Kelowna, county of Yale, in. the Province of British Columbia, Canada,have invented certain new and useful Improvements in Nozzles; and I do hereby declare that the following is 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.

The invention to be hereinafter described relates to nozzles.

G. Buelma of Santa Barbara, California, has patented a similar nozzle in which the flow of water and the distribution are not easily controllable.

The object of this invention is to overcome these difiiculties and produce a nozzle which is adj ustable so as to readily control both the rate of flow and the distribution of the ct or spray.

In order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several views of the draw ings, like reference characters designate the same parts.

In the drawings: Figure 1 is a front view of the outer shell of the nozzle; Fig. 2 is a front view of the inner shell of the same; Fig. 3 is a plan view showing the shape of the delivery opening through the outer shell; Fig. 4 is a similar view showing the delivery opening through the inner shell; Fig. 5 is a longitudinal section on line 55 of Fig. 6; Fig. 6 is a plan View of the complete nozzle, showing the parts assembled; and, Fig. 7 is a side elevation of the entire apparatus, as used.

Referring to the drawings in detail, 3 represents a tubular inner shell provided with a logitudinally extending trian ular opening 4. The outer or front end 0 this shell is closed, except where the opening 4 extends radially into it. The extension 4 of the opening 4 reaches to about the center of the end of the shell 3, and has a uniform width about equal to the widest part of the opening 4. Outside of this shell 3 is revolubly mounted a second tubular shell 1, provided with a triangular opening 2, 2 generally similar to that of the first shell and adapted to be brought partly into register therewith.

One of the long sides of the opening 2 is parallel with the longitudinal axis of the shell 1. The opposite side of the opening is parallel with one edge of the opening 4. In order to regulate the jet or stream passing through the opening 2, it is simply necessary to turn the outer shell slightly to make the openings 2 and 4 register more or less exactly. The entire flow may be quickly and easily cut off by simply turning the outer shell so that its opening does not in any degree register with the opening 4.

WVhen the two shells are in the position shown in Fig. 6, there will be a broad fanlike spray, as shown at the left in Fig. 7 the jet being under low pressure. The straight edge of the shell 1, of course, begins to overlap the opening 4 at the widest part of the opening, first. It will overlap practically one-half of the opening 4 before it acts upon the full length of the opening. It will be noticed, however, that the branches 4 and 9/ of the openings 4 and 2 are radial and extend from the centers of the ends of the shells to their outer edges, and that these branches are of practically the same width throughout. Consequently, as the outer shell is rotated, the overlapping of the adjacent edge of the radial opening 4 by the outer shell will increase much more rapidly to ward the outer end of the opening than at the opposite end. As a result of this construction, it is possible to completely close the longitudinal opening through the inner shell, while at the same time leaving the inner end of the radial branch 4 uncovered. The vertical jet is delivered through the opening 4 and the horizontal jet through the opening 4. Therefore, by rotation of the outer shell, it is possible to either reduce both jets simultaneously, or, by further turning of the shell, to completely out ofi the vertical jet and at the same time reduce the horizontal jet from a wide spray-like stream to a simple non-spraying jet. To effect locking of this outer shell, a thumb screw 5 is provided. The shank of this screw is adapted to play in an arcuate slot in the outer shell 1, and its lower end takes into the wall of the inner shell. Its head is provided with a shoulder which engages the face of the outer shell when it is turned down, and so locks the two shells together frictionally, preventing relative movement between them.

The particular formation of the openings 2 and 4 gives the jet or escaping spray both Patented July 19, 1910.

a forward and a side motion, thus distributing the liquid from the nozzle to greatest distance to which the nozzle will pro ect.

This nozzle may have a variety of uses as in sprinkling streets, lawns, and gardens and for fire protection. It is designed especially for use in irrigation work for irrigating large areas. For this purpose two nozzles may be mounted on opposite ends of a cross head 14 (Fig. 7) of a rotary spray mechanism 15. Theends of the cross head pipes are slightly bent and the nozzles turned through a slight vertical angle so as to cause the cross head to revolve by the reaction of the' escaping jet or spray. As the cross head rotates the ground from the center of rotation to the greatest distance to which the nozzle will project is sprinkled and the proper distribution is effected by adjusting the forward and side flow of the adjustable nozzles so as 'to get the desired results. The chief objection to this nozzle for this purpose is that it will not project to a great distance, therefore better results will be secured if on one end of the, cross head 14 another form of nozzle be substituted which will project to a greater dis tance covering, as the cross head 14 revolves, an annular space beyond the reach of the nozzle here described.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

1. A nozzle of the character described comprising an inner tubular shell having one closed end and provided with a longitudinally extending triangular delivery opening and a radially extending branch opening leading therefrom through the closed end of the shell, and an outer shell revolubly mounted on said inner shell and provided with openings adapted to cooperate with the openings in the inner shell.

2. A nozzle of the character described comprising an inner tubular shell having one closed end and provided with a longitudinally extending triangular delivery opening and a radially extending branch opening leading therefrom through the closed end of the shell, an outer shell revolubly mounted on said inner shell and provided with openings adapted to cooperate with the openings in the inner shell, and means for locking said outer shell in various adjusted positions.

3. A nozzle of the character described comprising an inner tubular shell having one closed end and provided with a longitudinally extending triangular delivery opening and a radially extending branch opening leading therefrom through the closed end of the shell, and an outer shell revolubly mounted on said inner shell and provided with cooperating openings, the walls of which are so disposed as to simultaneously reduce both openings of the inner shell, upon partial rotation of the outer shell, or, upon continued rotation to completely close the longitudinal opening of the inner shell while only reducing the radial opening therethrough, or, upon further continued rotation, to completely close both openings through the inner shell.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
