NOZZLE OF HOSE-PIPES.

Speccaton of Letters Patent No. 26,994, dated January 31, 1860.

To all ywhom 'it may concern:

Be it known that I, NIKoLAUs IIoTz, of Trenton, in the county of lWIercer and State of New Jersey, have invented a new and useful Improvement in the Construction of the Nozzles of Hose-Pipes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings'7 which make part of this specifica-- tion, andin which- Figure l represents a longitudinal, axial, section through a portion of a hose-pipe and nozzle embracing my improvement. Fig. 2 represents a view of the nozzle and coupling, as seen from above (with the former in section) showing more especially the relative position of the parts when the valve of the nozzle is opened to its greatest extent. Fig. 4 represents a similar view of the same, with the valve partially closed. Fig. 3 rep resents a similar view of the same with the valve closed still more than in the preceding figure; and Fig. 5 represents a similar view of the same with the valve entirely closed.

Owing to the general introduction of abundant supplies of fresh water into large cities their inhabitants are enabled to make free use of it for the purposes of cleaning, laying the dust, &c. but the employment ot the common hose pipe with an ordinary stopcock in the nozzle (to enable the person using it to shut otf the iiow at will) is attended with much inconvenience and expense of construction. To obviate the objections to which this construction of nozzle is subject I have invented a. new article of manufacture, constituting an improved hose-nozzle, cheap and simple in its construction and of great durability; and my invention consists in so constructing the nozzle for hose, whether used for extinguishing tires or for cleansing purposes, as that while the common stopcock is entirely dispensed with, the flow of the water may readily be regulated at the pleasure of those to whom the use of such hose may be necessary or convenient. To accomplish these objects I arrange a perforated diaphragm, disk, or plate, ot elastic material, within the discharge-pipe in such manner that it shall work in contact with an auxiliary diaphragm, disk, or plate, corre spondingly perforated and attached to the nozzle of said pipe, which nozzle is so arranged as to revolve on the pipe to open and close its valve.

To enable persons skilled in the art to make and use my improved nozzle I will now proceed to describe its construction and mode of operation.

In the accompanying drawings the pipe (a) and nozzle (b) are represented as con nected by the nut or coupling (c). The nozzle (o) has a rim or ange (d) on one end to hold it within a corresponding rim (c) on the nut (0); by which means the nozzle is left free to turn within the coupling but cannot escape therefrom. A plate (f), which I call the nozzle-plate, extends across the end of the. nozzle, and has openings (g) through it in the form of sectors of a circle, for the `passage ofl the water. The pipe (a) has a male screw on one end which takes' into a female screw in the coupling A plate (71,), which I call the pipe-plate, similar to the one already described, except that it is made of leather, gutta-percha, india-rubber, or some other elastic material is placed against the end of the nozzle (b), within the coupling and the pipe (a) screwed in; thereby forcing the plates (/L, and into close contact, and forming a tight joint. This plate (h), after being so placed in the pipe that its openings occupy the proper relative position to those of the nozzle-plate (f), is prevented from turning by a projection on the inner side of the pipe.

The operation of the nozzle is a follows. Suppose the plates (f, h) to be in the position represented in Fig. 2, of the drawings,

that is with their apertures opened to their greatest capacity. Now if a diminution in the flow of the liquid is desired, it is only necessary to grasp the pipe with one hand and turn the nozzle on its axis with the other, by a pivotal movement, and the plates will gradually slide over each other until they assume the position shown in Fig. 4:, when the low will be diminished; and by continuing this movement until the parts assume` the position shown in Fig. 5, the flow will be entirely checked.

A suitable stop or catch (i) on the nozzle, traverses a notch in the coupling, and prevents the nozzle from being turned so far as to reopen the discharge apertures.

The nozzle-plate being made of metal is consequently very durable, and may if preferred be cast in one piece with the nozzle. The pipe-plate is made of some elastic material (as above mentioned) and is held closely' against the nozzle-plate by the hydrostatic pressure of the water, as well as by the screw, by which means any tendency to leakage is eii'ectually prevented. If however the plate should become worn out or de- :Eective it may readily be removed by unscrewing the coupling, and a new plate substituted. By this method of construction I am eanbled to secure a hose-nozzle which is cheap and simple in construction, durable and eiicient in operation, and easily adjusted or repaired when out of order.

It is obvious that my invention is a decided improvement over those nozzles which though somewhat similar to mine in some respects, yet have the cock operated by an independent handle, which is always catching in something and impeding the handling of the pipe, besides being much more complex and costly in construction.

I do not claim broadly a valve composed of two perforated disks or plates sliding over each other, as I am aware that this is a Well known device, but I claim as a new article of Ymanufacture- A hose-nozzle constructed as herein set forth.

In testimony whereof I have hereuntoisub-l scribed myname.
