SPECIFICATION forming part of Letters Patent No. 614,883, dated November 29, 1898. Application filed January 31, 1898- Serial No. 668,624. (No model.)
To all whom it may concern.-
Be it known that we, HORACE FALK NEU- MEYER, residing at Macungie, in the county of Lehigh and State of Pennsylvania, and JONAS FRANCIS YOUNG, residing at Niagara Falls, in the county of Niagara and State of New York, citizens of the United States, have'invented a new and useful ater-Nozzle, of which the following is a specification.
This invention relates to improvements in water-nozzles of the class disclosed in the application for United States Letters Patent, filed jointly by H. F. Neumeyer and J. F. Young 011 August 17, 1897, Serial No. 648,582; and the object in view in the present invention is to simplify and cheapen the construction by reducing the parts to the smallest possible number necessary to attain the functions of a nozzle adapted to perform the twofold purpose of delivering a solid stream or a spray, the density or fineness of the spray being controllable at the will'of the'operator.
The invention consists of a nozzle having a delivery-tube which is formed externally with a T- shaped pivot recess or groove in rear of an inclined seat or face which intersects the delivery-orifice of said tube, a spraying-plate having a T-shaped head fitted loosely in said recess or groove, an outer tube which fits snugly over the recess or grooved part of the delivery-tube and serves to confine the spraying-plate adj ustably in place in the groove or seat without the employment of separate pivotal pins or screws to adjustably attach the spraying-plate to the delivery-tube, and means for varying the movement of the sprayingplate with relation to the delivery-tube.
The invention further consists in the combination, with the delivery-tube and a spraying-plate pivotally attached thereto, of an outer tube connected to the nozzle to inclose -the spraying-plate, and an adjustable stopscrew mounted in the outer tube in the plane of the spraying-plate and having direct contact or engagement therewith, whereby the pressure of the water against the sprayingplate deflects or moves the latter with relation to the delivery-tube, and the adjustable stop-screw serves as a fixed stop to limit the lateral movement of the spraying-plate; and
the invention further consists in the novel construction and arrangement of parts, which will be hereinafter fully described and claimed.
To enable others to understand the invention, it is illustrated in the accompanying drawings, forming .a part thereof, and in which Figure 1 is a perspective view of a complete water-nozzle constructed in accordance with this invention. Fig. 2 is a perspective View of the nozzle with the outer tube and the stop-screw removed. Fig. 3 is a longitudinal sectional view through the nozzle illustrated by Fig. 1. Fig. 4 is an elevation looking at the delivery end of the nozzle.
Like numerals of reference denote like and corresponding parts in each of the several figures of the drawings.
1 designates the body of the improved sprayno'zzle, which at its rear end is constructed with an enlarged attaching-gland 2. This attaching-gland is interiorly threaded to provide for the attachment of a hose-coupling to the receiving end of the nozzle, as is usualin the art. At its front end the body 1 is constructed with an integral delivery-tube 3, which projects beyond the body for a considerable distance and is arranged in line with the longitudinal axis of said body, and through the body and the delivery-tube is formed an axial water passage-or way 4, the rear end of which opens centrally into the attaching-gland 2 of the nozzle. Between the delivery-tube and the attaching-gland the body 1 is formed with a transverse valve-seat 5,which intersects with the longitudinal water way or passage 4, and in this transverse seat is fitted the plug-valve 6, which is formed with a transverse port 6, adapted to coincide or aline with the water-passage 4 and permit the water to pass through the nozzle. This plug-valve 6 is similar in construction to prior devices of this class and one end thereof is formed with a thumb-piece 7, by which the valve may be conveniently turned in its seat to permit the water to pass through the nozzle or to cut off the flow of water, as may be desired.
At the front end of the delivery-tube 3 is formed a beveled surface 8, which lies on one side of the tube and inclines inwardly toward the delivery-orifice thereof, so that the inclined face intersects with the delivery-orifice. This inclined face 8 constitutes a seat for the spraying-plate presently referred to, and the delivery-tube is constructed with a collar or flange 9, which is situated or formed exteriorly on said delivery-tube in rear of the inclined seat or face 8 thereof. This flange or collar 9 projects beyond the delivery-tube a suitable distance and it is formed with a T- shaped groove or recess 10, one leg or member of said T-shaped groove being in line with the inclined face or seat 8 of the delivcry-tube.
11 designates a spraying-plate which, as shown in the drawings, is of substantially flat form, but is tapered longitudinally to approximately the shape of a wedge, and the narrow end of this spraying-plate is formed with a T-shaped head 12, that is adapted to fit snugly in the T-shaped groove or recess 10 of the collar 9.
The deliverytube, its collar 9, and the spraying-plate are housed or inclosed within the outer tube 13. This outer tube is of a diameter to fit snugly to an annular ledge or flange 22, which is formed on the end of the nozzle-body 1 in advance of the cut-0E plug oimvalve (3 therein.
The manner of mounting or hinging the spraying-plate of the delivery-tube and the arrangement of the outer tube on the body to confine the spraying-plate in place is disclosed substantially in the prior application hereinbefore referred to, and is not claimed therein, but is claimed in our present application.
The grooved collar 9 is of segmental or are shape and is arranged to fit snugly within the outer tube 13, thus forming a seat for the outer tube. On the opposite side of the delivery-tube 3 from the collar 9 is provided a lug 23, that is adapted to bear against the inner face of the outer tube 13 and also form a seat therefor, and the nozzle-bodyis further provided with a lug 15, which is in alinement with the lug 23, to provide a seat for the outer tube and receive the fastener by which said outer tube is held securely in place on the nozzle-bod y. This In g 15 has a screw-hole 16 tapped therein, and the outer tube 13 is provided with a transverse aperture 19, adapted to coincide with the threaded hole 16 and permit the fastener-screw 17 to be screwed into the lug 15, thus confining the outer tube securely in position on the nozzle-body.
In the improved nozzle the spray-plate is fitted laterally against the inclined seat or face 8 on the delivery-tube 3 of the nozzle, and the head of said spraying-plate lies within the recessed collar 9, within or below the segmental edge of said collar. The outer tube is adapted to fit snugly over the recessed collar, and it thus confines the head of the spraying-plate loosely or pivotally in place within the recessed collar. The described construction and arrangement of the spraying-plate and the outer tube obviates the necessity for pivoting or riveting the spraying-plate to the nozzle-body, and the parts are adapted to be readily assembled and fitted together, whereby the simplicity of the nozzle is promoted and its manufacture cheapen'ed.
From the foregoing description, taken in connection with the drawings, it will be seen that the spraying-plate is fitted to the delivery-tube of the nozzle to have the free end of the spraying-plate extend part way across the delivery-orifice of the tube 3, and that the spraying-plate is pivotally or loosely confined in position on said delivery-tube of the nozzle. The spraying-plate is thus arranged directly in the path of the water which may pass through the delivery-tube 3,and the pressure of the water against the spraying-plate tends to force said plate laterally away from its seat 8 on the delivery-tube. To regulate the position of the sprayingplate with reference to the delivery-tube 3 and to enable either a solid stream or a spray to be delivered by the nozzle, an adj usting-stop 20 is provided to have direct contact with the spraying-plate and to limit the movement thereof under the pressure of the water flowing through the nozzle. In the preferred embodiment of the invention this adjustable stop is in the form of a screw 20, the threaded shank of which is fitted in a threaded bearing or opening 21in the outer tube 13. This stop-screw is pro- Vided with a milled head 20", by which it may be conveniently turned and adjusted. The stop-screw is fitted adjustably in the nonrotatable outer tube 13 to lie in the plane of the loosely-hung spraying-plate 11, and the inner end of said stop-screw is thus arranged to have direct contact with the spraying-plate for the purpose of limiting the outward move ment thereof under the pressure of the water.
The described construction of the nozzle wholly obviates the employment of springs to normally force the spraying-plate away IIO from its seat on the delivery-tube and toward the outer tube, and the outer tube is a stationary part of the nozzle instead of being rotatably fitted thereon and equipped with means to determine the adjustment of the spraying-plate with relation to the delivery-tube, thereby materially simplifying the construction of the nozzle and cheapening its cost of manufacture.
In a prior patent to H. F. Neulneyer, No. 525,507, dated September 4, 1894, an outer tube is provided with tapering slots in the plane of the pivoted spraying-plate, which is normally pressed to an inclined seat across the discharge-orifice of a delivery-tube; but it is objectionable for many reasons to employ these inclined slots for the purpose of delivering the spray laterally of the nozzle.
In the improved construction of the nozzle forming the subject-matter of this application an outer tube is employed, which is practicallyimperforated except for the openings 19 and 21, which receive the screws 17 and 20, respectively, and the delivery end of the outer tube 13 is flared or constructed with a bell-shaped mouth 14, through which the spray is delivered without hindrance and to the best advantage.
The improved construction of the nozzle provides for throwing a solid stream or a spray, according to the position of the spraying-plate 11 with relation to the delivery-tube 3, and the position of this sprayingplate is determined solely by the pressure of Water against the plate and the limit of its adjustment permitted by the stop-screw 20. When the stopscrew is retracted to permit the spraying plate to be deflected directly out of the path of the water issuing from the delivery-tube 3,
. the water is free to escape with a minimum resistance from the spraying-plate. Hence a solid stream is delivered. By turning the stop-screw inwardly and forcing the sprayingplate across the delivery-orifice of the tube 3 the spraying-plate is caused to otfer resistance to the water and break the same into a sheet or spray, and the density or fineness of the spray is proportionate to the angle of the spraying-plate with relation to the axial line of the delivery-tube.
The improved nozzle is extremely simple in construction, cheap of manufacture, well adapted to serve either as a nozzle for delivering a spray or solid stream, and is equipped with means for cutting off the bolt of water through its delivery-tube.
It is evident that changes in the form and proportion of parts may be made by a skilled mechanic without departing from the spirit or sacrificing the advantages of the invention.
