NOZZLE.

Specification of Letters Patent.

Patented July 19, 1910.

Application filed April 19, 1909. Serial No. 490,884.

To all whom it may concern:

Be it known that I, GL iMEN'r VAOHER, a subject of the King of Great Britain, residmg 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 improved nozzles.

As heretofore constructed, it has been impossible to project a finely divided spray to any considerable distance. As the pressure is increased, the particles are more finely divided, offering more resistance to the air, and therefore the distance to which the spray is projected is not materially increased. The ordinary circular conical. nozzle, while projecting to a considerable distance, will not properly distribute the water.

The object of this invention is to overcome these difficulties by means of an improved nozzle or nozzle attachment, which will project water to a greater distance than the ordinary circular conical nozzle, and at the same time to be so adjustable as to properly distribute the water or convert any portion of the escaping jet into a spray.

In order to more clearly disclose the construction, operation and use of the invention, reference should be made to the ac-- companying drawings forming a part of the present application.

Throughout the several'views of the drawings, like reference characters designate the same parts.

In the drawings: Figure 1 is a side elevation of the nozzle; Fig. 2 is a longitudinal section through Fig. 1; Fig. 3 is a cross section of Fig. 1, with the vanes inoperative; Fig. 4 is a similar view with the vanes operative; and, Fig. 5 is a side elevation of the nozzle as it may be used on an irrigation sprinkler apparatus.

Referring to the drawin s in detail, the nozzle proper is made up of an outer cylindrical shell 8 revolubly mounted on an inner shell 9. The inner shell is provided with slots in which are pivotally mounted a plurality of concave vanes 10, each having heel pieces 11 adapted to engage the walls of notches 12 formed in the inner face of the outer shell. The outer shell 8 may be r0- tated at will about the innershell 9.

To look the outer shell 8 in any position a thumb nut 13 is provided. The shank of this nut is adapted to play in an arcuate slot in the outer shell 8, 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 the nut is turned down, and so locks the two shells together frictionally, preventing relative movements between them. The inner shell 9 is boredout at its rear end to form a seat for the end of a pipe or other connection. At the end of this bore is formed a partition provided with a conical opening in which is removably seated a tapered jet tube 14:. This jet tube is provided with an inner shoulder adapted to engage the face of the partition and act as a stop or limit. \Vhen in position, the tube will be securely clamped between the face of the partition and the end of the pipe. By having the jet tubes removable, it is possible to change them according to the changes in the water pressure, the different tubes being provided with orifices of different diameters.

There is considerable friction of the escaping jet on the walls of the nozzle and when the vanes or knives cut off the outer surface of the jet, the remaining core is pro ected to a greater distance than would be the case were the vanes or knives inactive and the water out off by the vanes is distributed in the form of spray. This feature is of great value for many purposes, as in sprinkling streets, lawns, fighting fires, irrigation, etc., or in any place where it is desirable to have an adjustable nozzle throwing either a jet or a spray or a combination of both. The nozzle may be manufactured complete in itself or the part containing the adjustable vanes or knives may be manufactured as an attachment to the ordinary nozzle.

For irrigation work two of these nozzles may be mounted on opposite ends of the cross head 14. (Fig. 5) of a rotary spray mechanism 15. The ends of the cross head pipes are slightly bent and turned slightly through a vertical angle so as to cause the cross head to revolve at any desired speed by the reaction of the escaping jet. These nozzles will project to a great distance and at the same time distribute water over an annular space at a considerable distance from the center of rotation. However, better results will be secured if on one end of seat bore in one end and longitudinal slots 7 in its walls, vanes movably mounted in the slots, an outer sleeve revolubly mounted on the inner shell, connections between the outer shell and the vanes, and a jet tube removably seated in the inner shell.

2. A nozzle of the character described, comprising an inner shell provided with a seat bore in one end and a partition having an opening, an outer shell mounted on the inner shell, blades movably mounted in the inner shell, connections between the blades placed a nozzle of the kind and the outer shell, and a jet tube adapted to be removably seated in the opening in said partition.

3. A nozzle of the character described, comprising an inner shell provided with a seat bore in one end and a partition having an opening, an outer shell mounted on the inner shell, blades movably mounted in the inner shell, connections between the blades and the outer shell, and a jet tube adapted to be removably seated in the openin in said partition, said jet tube being provlded with a shoulder adapted to engage the face of the partition to limit the insertion of the tube.

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