NOZZLE.

Specification of Letters Patent.-

Patented Aug. 22, 1905.

Application filed October 10, 1904:. Serial ,No. 227,854.

To all whom it may concern.-

Be it known that we, FREDERICK L. TITS- WORTH, of Kenosha, Wisconsin, and HOWARD B. SHERMAN, of Battlecreek, Michigan, have invented certain new and useful Improvements in Nozzles; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in hosenozzles, and in particular is an improvement slight modifications of the construction of the spindle, all embodying substantially the same novel features, and we will describe the invention as illustrated in the drawings and refer to the claims for summaries of the-particular parts and features of construction constituting the invention and for which protection is desired.

In said drawings, Figure 1 is a longitudinal section through the nozzle open, showing the spindle in elevation. Fig. 2 is a side view of the nozzle closed, partly in section, showing a slight modification of the hose connection. Fig. 3 is a side view of a part of the section with a slight modification of the construction of the spindle. Fig. 4 is a section on line 44, Fig. 3'. Fig. 5 is a rear end view of the spindle shown in Fig. 3. Fig. 6 is a detail elevation of another slight modification of the spindle. Fig. 7 is a section on line 7 7, Fig. 6. Fig. 8 is an end view of Fig. 6.

A designates the hose connection or base of nozzle, comprising an internally threaded socket portion (4, adapted to be screwed onto the ordinary nipple attached to the end of a hose or pipe and provided with a contracted neck a, to which the valve-spindle B is attached, and on which neck slides the stuflingbox F, attached to the rear or inlet end of the adjustable sleeve, which incloses the spindle.

The spindle B comprises a central stem or rod portion B of much smaller diameter than the interior of the sleeve E or neck a, but arranged axially thereof, and is connected to the neck by means of an enlargement orbutt B on its rear end, which is closely fitted within the outer end of the neck and may be secured thereto in any suitable manner. We preferably secure it either by wiping or sweating it therein or riveting it. In Fig. 3 it is shown as secured by a rivet b and in Fig. 6 it is shown as secured by wiping or soldering. Beyond the butt B the stem is provided with a threaded enlargement or boss-section 13*, which is externally screw-threaded, as at b, to engage the internal threads 0 of the sleeve E, which said sleeve may be, and preferably is, constructed substantially as described in the aforesaid Sherman patent. The engagement' of the sleeve with this threaded section or enlargement B ofthe spindle and through the stuffing-box F with the neck a of the base A keeps the sleeve in axial alinement with the spindle and neck and allows it to move longitudinally thereof, as is necessary to open or close the nozzle. The sleeve has an outlet 0 in its outer end, adapted to be closed by a valve 7/ on the outer end of the spindle-stem B, substantially as described in said Sherman patent.

The threaded enlargement B and the butt B may be formed integrally with or separately from the stem B. As shown in Figs. 1 and 6, they are formed integral therewith; but preferably, and as shown in Figs. 2 and 3, they are formed separately therefrom and secured thereto by rivets, as inFigs. 3, 4E, and

5, or by wiping or soldering, as indicated in Fig. 2.

In order to afford free passage of water the butt of the spindle is preferably formed with peripheral longitudinal channels B as indicated in Figs. 2, 3, and 5, or it may have axial perforations b, as indicated in Figs. 6 and 8. is preferably provided with peripheral longitudinal channels If, as indicated in Figs. 3 and 4, or may have longitudinal passages 6 asindicated in Figs. 6 and 7. In either case. it will be observed that a practically direct and Similarly the enlargement or boss B continuous passage is afforded for the water from the base A to the outlet 0', there being no abrupt or sudden deflections of the water current to lessen the force thereof. By this construction, furthermore, we can obtain a larger sectional area of water-passage through the nozzle as compared with theordinary construction in which the spindle is tubular and the water conducted axially therethrough.

The described construction obviously requires less metal in the spindle than is necessary where it is made tubular with a central water-passage and is easier to manufacture and less costly.

The spindle might be made from a rod having longitudinal grooves and irregular sections, such as indicated in Fig. 4, for example. In this case the butt and enlargement could be formed integral with the stem B; but preferably the butts and enlargements may be cut from rods of suitable section and secured to a stem of proper diameter, as above explained.

Apacking-ringGand packing g are slipped on the neck between the stufling-box and end of the sleeve, and in order to prevent the stufling-box and sleeve being accidentally moved off the neck the butt may be provided with peripheral projections B, as indicated in Fig. 1, which extend outward slightly beyond the outer diameter of the neck and prevent the stufling-box coming off, or in the form shown in Figs. 6 to 8 the butt may have a peripheral flange B for this purpose, or in the structure shown in Fig. 2 the inner end of the neck a may be provided with an outturning flange a for such purpose. Any of these constructions will prevent the stuffing-.

box being pulled off. Preferably the butt is constructed to form the stop for the stuffingbox, as it facilitates the assembling of the parts, since the stuffing-box .can be freely slipped on the neck before the spindle is attached thereto.

The base and spindle may be formed of d rawn or spun metal, as described in said Sherman patent, or cast. The stuffing-box may be made of drawn or spun metal, from rod-brass, or cast or in any other regular way. The spindle may also be formed integrally from rolled rods, or the stem of the spindle may be formed from one rod and the enlargement and butts formed from other rods and afterward connected to the stem, or the enlargement and butt may be cast and attached to the. stem afterward. The spindle may be formed from a large rivet or from a rod with the tip screwed on, riveted on, or soldered on, the screw portion riveted on, soldered on, or attached in other way and with the rear portion fastened on in like manner. In other words, this spindle may be made of fluted rod, or it may be made of a small round rod with the other pieces attached, or it may be made of a rivet. In this case the head of the rivet would be used to form the tip and the other two portions would be secured thereon in suitable manner. We do not restrict ourselves to either cast, wrought, or spun metal in the construction of the nozzle.

If the stem, butt, and enlargement are made integral, as indicated in Fig. 1, from a fluted rod, or cast, the construction, as compared with that in Shermans patent, No. 742,133, is much cheaper, as it requires much less metal and less machine-work than the spindle shown in said patent. Parts of spindle are made integral. Instead of using round rods we use specially-shaped rods of cross-section corresponding to the section in Fig. 4, so that the water-channels 72 12' are formed in drawing the rod. These channels in the rod materially lessen the waste and work required in reducing the intermediate or stem parts to desired form. The preferred formto wit, that in which the butt, enlargement, and stem are formed separately and assembled as indicated in Fig. 3, is even more economical in construction than that shown in Fig. 1. the butts and enlargements are cut from rods having the sectional contour indicated in Figs. 4 and 5.

The operation of the nozzle is obvious from the drawings and is so well understood that explanation thereof is unnecessary.

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

1. Ahose-nozzle comprisingabase, asleeve, and a spindle within the sleeve attached to the base, said spindle comprising a solid axial stem of small diameter, a butt of larger diameter on the rear end of the stem and attached to the base, said butt having longitudinal water-channels in its periphery exterior to the stem, and an enlargement on the stem in advance of the butt having exterior threads to engage the internal threads of the sleeve and longitudinal water channels in its periphery exterior to the stem, substantially as specified.
