FRANCIS M. BOOKlVALTER, OF SPRINGFIELD, OHIO.

HYDRAULIC MUZZLE.

SPECIFICATION forming part of Letters Patent No. 579,418, dated March 23, 1897.

Application filed January 6, 1896. serial No. 574,477. (No model.)

To coZZ whom, it may concern:

Be it known that I, 'FRANoIs M. BooKwAL- TER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Hydraulic Nozzles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in hydraulic nozzles.

The object of my invention is to provide a hydraulic nozzle designed especially, though not exclusively, for use in connection with water-wheels,particularly of the hurdy-gurdy type. This object is carried out by the construction and arrangement hereinafter fully described, and particularly pointed outin the claims.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure l is a vertical sectional view of a nozzle embodying myinvention, the section being taken on the line amof Fig. 2; Fig.2, a horizontal sectional view of such nozzle on the line 3 y of Fig. 1; Fig. 3, an end elevation of the mouth of the nozzle; Fig. 4., a transverse sectional view on the line a a of Fig. 2; Fig. 5, a similar sectional view on the line (L a of Fig. 2; Fig. 6, a similar view to Fig. 1, illustrating another form of reducing mechanism; Fig. 7, a similar view to Fig. 2, also illustrating such other form of reducing mechanism; and Fig. 8, an elevation of the discharge end of the nozzle, showing such modified form.

The letter A designates what may be termed the supply or feed pipe with which my nozzle will usually be used, and the letter B the nozzle proper, consisting of a casin g formed in one or more parts, but preferably of the sides 0 and D, top E, and bottom D, thus forming a rectangular structure in crosssection through bolts and nuts F, passing through the sides and securing the top and bottom thereto.

The nozzle is tapering in one direction, as seen in Figs. 2 and 7, and is secured to the pipe by flanges G and bolts and nuts H.

The sides 0 andD of the nozzle are formed with recesses I, which constitute bearings for the trunnions J of the reducing mechanism.

Thus the latter are oscillatory within the cas ing, turning on their trunnions.

From Figs. 2 and 4 it will be seen that the trunnions J are united to the plates or wings K, which constitute the reducing mechanism, by means of webs L, which webs snugly fit the inner surfaces of the top and bottom of the nozzle and so make practically water-tight joints. The trunnions snuglyin bearings I and further form such a joint. The wings or plates K are of the form shown, being tapering and fitting the top and bottom of the nozzle, as seen in Fig. 5 at M, while their inner surfaces more or less approach each a semicircle. hen these reducers are swung to bring their discharge ends together, the.

stream is smallest and will grow larger and larger in diameter as their said ends recede. Their said ends are also each provided with a flange O, which stands across the sides C and D of the nozzle and diverts leakage that might occur, so that such leakage will be thrown out of the way from the stream and not interfere with its symmetry. The inner ends of the reducers are connected each by a link P with a crossed head Q, on a handshaft R,

V which is mounted in the top and bottom of the nozzle and passes through the stuffing boX. S to prevent leakage. By turning the shaft R the reducers are operated to vary the size of the stream.

Referring to Sheet 2, Figs. 6 to 8, inclusive, it will be seen in that modification I employ but one wing K or a single reducer, utilizing the opposite wall D of the nozzle for such reducer to cooperate with in controlling the diameter of the stream. The construction is otherwise the same, however, as in the other figures. Thus it will be seen that I control the diameter of the stream by gradually contracting or enlarging it from a point well within the discharge end of the device and without any sudden or abrupt contraction of the discharge-orifice, a valuable feature in practice. Thus also it will be seen that I make the mountings of the reducers act as a cut-off to prevent escape of the water back of the reducers, or a single reducer, as the case may be. It will also be noticed that the operatingshaft is connected with the inner ends or end of the blade or blades, as the case may be, and that such blade or blades are ex tended inward beyond the pivot, so that the incline or taper which directs the water is rendered as little abrupt as possible.

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

1. In a nozzle, the combination with a casing constituting the nozzle proper, of reducing mechanism in the form of a tapering blade having a trunnion substantially midway its length, said trunnion being mounted in a recess in the side wall of the casing, said blade being fitted snugly to the upper and lower walls of said casing, and an operating rockshaft mounted in the casing near the inner end of said blade, and connections between said rock-shaft and said inner end of the blade to control and adjust said blade by holding said inner end of said blade, and adjusting the same to and from the side walls of the 20 casing.

2. In a nozzle, the combination with a rectangular casing constituting the nozzle proper two of whose walls have recesses, of reducing mechanism consisting of two wings or blades with curved interiors and end flanges, with trunnions and webs mounted in and snugly fitted to said casing constituting a substantially water-tight joint, and a shaft mounted in said casing, with a cross-head and links connected to the inner ends of said wings or plates.

In testimony whereof I aflix my signature in presence of two witnesses.
