HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 243,938, dated July 5, 1881.

Application filed March 23,1881. (ModeL) T all whom it may concern:

Be it known that I, EDWIN MEDDEN, a citizen of the United States, residing at Seneca Falls, in the county of Seneca and State of New York, have invented Improvements in Hose-Nozzles, of which the following is a specification.

In hose-nozzles of the usual construction a serious defect exists in the vortical or whirl- :0 ing motion imparted to the water, whereby the stream is caused to separate into spray, and is consequently prevented-by atmospheric resistance from reaching so great a distance as can be reached by 'a compact stream. Various expedients have been devised for preventing this defect by the introduction of 1011- gitudinal flanges or wings within the nozzle. Under one system radial flanges are secured to the interior surfaces of the nozzle, projecting to some distance inward without meeting; in another removable blades or flanges have been applied, connected at the center, but detached from the body of the nozzle, so that they can be taken out. Ihave found by expe- 2 5 rience that this arrangement is not reliable, for the reason that the spiral action of the water, when under great pressure, causes the wings to twist and break, and when they become in the slightest degree distorted they are liable 0 to impede the stream, and the water passing through the center wears away the joint, so that it is difficult to make them strong enough unless they are made so thick that they obstruct and impede the stream.

My invention consists in securing blades permanently within a nozzle by forming two blades of one piece of metal bent at an angle, and firmly securing to the said angle a third blade by means of a flange or lap of a quarter of an inch, more or less, so that they can be fastened together very securely by brazing or soldering. The single wing is also riveted at each end to the double ones, so as to make the connection perfectly secure.

In the accompanying drawings, Figure 1 is a plan view of my improved nozzle, partly in longitudinal section. Fig. 2 is a transverse section on the line 2 2, Fig. 1. Fig. 3 is a perspective view of the triple blades.

A represents a hose-nozzle, which may be of ordinary external form. B B O are three blades, the blades B B being formed of one piece of thin sheet metal bent at an angle of one hundred and twenty degrees, if three blades are employed, as in the present illustration. The third blade is made of a single plate of similar sheet metal, with the flange or lap c brazed or soldered at the angle of the blades B B, and also secured thereto by rivets (1, near the ends, so that the three plates B B 0 will occupy radial positions at equal angles. The connecting-plates thus made are firmly secured by their outer edges to the interior of the nozzle A, as illustrated in Figs. 1 and 2.

I am aware that hose-nozzles have before been constructed with removable wings connected together at the center, and that others have been made with fixed wings projecting radially inward and disconnected at the center. My invention therefore does not extend to either of these devices; but I have found both of them seriously and radically defective, owing to liability to distortion under the forcible torsional strain to which they are subjected by the action of the water. My invention is therefore limited to longitudinal wings connected together at the center, in the manner. described, and permanently attached by their edges to the interior of the hose-nozzle.

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

A hose nozzle constructed as herein de scribed, with. radial internal blades formed of sheet metal connected atthe center and permanently secured by their outer edges to the interior of the nozzle, as explained.

EDWIN MEDDEN.
