No. 628,907. Paten'ted .Iuly |899.

M. H. HART.

Hose NozzLE.

(Application filed. Kar. 8, 1899.)

MILTON H. HART, OF WINOHESTER, MASSACHUSETTS.

4 SPECIFICATION forming part of Letters Patent No. 628,907, dated July 11, 1899.`

Application filed March 8, 1899. Serial No` 708,178. (No model.)

T0 all whom, t may con/cern:

Be it known that I, MILTON H. HART, a citizen of the United States of America, and a resident of Winchester, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Hose-Nozzles, of which the following is a specification. p

This invention relates to hose-nozzles and it has for its object to improve the construc tion thereof.

Heretofore, so far as known to me, hose-noz- 'zles have been so constructed that when the valve-plug of the nozzle occupies its closed position the valve opening or hole through the valve-plug is closed at each end by the casing of the nozzle, so as to forni a closed compartw ment, within which liquid will be conned and will remain so long as the valve occupies its closed position. Vhen the hose-nozzle is employed on fire-extinguishers, the soda or acid contained in the extinguisher will after it has remained in the valve-opening a comparatively short while corrode the metal with which it comes in contact and cause the valveplug to stick or bind, thus preventing the nozlzle from being readily manipulated. This is objectionable for obvious reasons, and it is the object of the present invention to improve the construction of hose-nozzles to the end that the above-noted objections may be obvi- -ated and also that the valve-plu g may be readily adjusted to compensate for wear and also that the bearings of said valve-plug and ad jacent parts may be readily lubricated.

The invention consists of -a hose-nozzle so constructed that the valve when in its closed position is adapted to register with an opening formed through the casing, whereby any liquid contained in the valve-opening may be discharged therefrom.

The invention also contemplates other new land useful features of construction and ar-` rangement of parts, all as is hereinafter more fully set forth in the following description and the novel features of which are particularly pointed out and clearly defined in the claims at the close thereof.

In the following description reference is had to the accompanying drawings and to the letters of reference marked thereon, like letters representing the same parts or features, as the case may be, Athroughout the several views.

Of the drawings, Figure l is an elevation,

l shown partly in section, of a hose-nozzle enibodying this invention. tion, shown partly in section, of the hosenoz zle shown in Fig. l as viewed from the righthand side of said figure. Fig. d is a longitudinal sectional view of the lower portion of Fig. 2, showing the valve in its closed posi tion. Fig. 4 is an elevation of the lower portion of the casing of the nozzle and illustrating certain features of this invention.

A represents the casin g of the nozzle7 which is formed or provided with a tapering valveplug socket a, within which socket is arranged the tapering valve-plug h. The valve-plug h is formed with a transverse valvefopening c, which by rotating the valve-plug may be caused to register with and connect the inletport CZ and outlet-port e or to close said ports, as is usual in nozzles of this character.

Fig. 2 is an eleva- A' Ordinarily when the valve-plug of the noztofore been confined in said opening until the'v valve is again opened. TWhere the nozzle is used on ,iire-extinguishers, the acid or soda contained therein will, after remaining in the opening c a com parativelyshort while, so corrode the metal with which it comes in contact as to cause the valve-plug to stick or bind, so that the nozzlel cannot be manipulated. To obviate this objectionable feature, I provide one or more (two being shown in the drawings) ports f, formed or provided in the casing A, with which the opening c will register when the valve-plug Z9 occupies its closed position, and through these ports fany liquidcontained inthe opening c may discharge therefrom to the outside of the casing. The ports f are closed by the plug Z9 when the latter is moved into position to connect the portsv d and e.

The valveplug bis made tapering and fits into the tapering socket a, and it is desirable IOO ` threadedto receive upon them the nuts b3 b",

which latter bear against the side of the casing A, and after being properly adj usted upon the projections b b2 said nuts are secured in their adjusted position by means of setfscrews b5 and be.

As shown in Fig. 4, that portion of the casingA adjacent the socket d and against Which the nuts b3 and b4 bear is cut away or grooved, as at 117, so as to provide an opening for the ready insertion of suitable lubricant for the bearing-surfaces of the casing-A and the nuts.

To the projections b' b2 is secured a handle C by'means of set-screws c', and by means of this handle the valve-plug may be operated. The handle C is provided with projections c2 and c3, which by engagement With the casing A limit the extent of movement of the Valveplug in both directions and serve to position' the valve-openin g c with relation to the ports d and e andf. The plug l) may also be further lubricated byinserting the lubricant through the ports f.

What I claim isl. The combination of the casing A provided With the tapering socket d and having` the ports CZ and c and f communicating therewith, the tapering valve-plug l), and means for adjustably securing said plug in position whereby said plug may be adjusted longitudinally to compensate for Wear, substantially provided with grooves or channels bl at said. n

bearing-points, substantially as described.

Signed by me, lat Boston, Massachusetts, this 21st day of February, 1899.
