UNIVERSAL NOzzLE.

SPECIFICATION forming part of Letters Patent No. 525,487, dated September 4, 1894.

Application tiled June 30, 1893.

To wZ'Z whom, it may concern.-

Be 1t known that I, WILLIAM K. CRAWFORD,

, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement 1n Universal Nozzles, of which the following description, in connection with the accompanylug drawings, is a specification, like letters on the drawings representing like parts.V

This invention relates to universal nozzles of the class shown and described in United es Patent No. 245,007, dated August 2,

The device shown in the patent referred to consists essentially of a revoluble shell provided with a conical seat which receives a rotatable plug carrying'A the nozzle. The outlet opening in the plug which leads to the nozzle 1s made flaring or tunnel-like to permit the plug with the nozzle to be rotated through a certain arc to direct the stream in dierent directions, and still preserve communication between the inlet and the nozzle through the outlet opening in the plug. In the device shown in the patent referred to, however, the plug fits its conical seat tightly throughout its length at that side at which the water inlet is located, the result being that the nozzle cannot be directed below a horizontal position without partially closing the inlet, and the lower the nozzle is directed, the more will the inlet be closed by the plug. The inlet cannot be made'more flaring for practical reasons, the result being that the range of the device is unduly limited.

This invention has forits object to improve devices of the class shown in the patent referred to, whereby the range of the device may be very greatly enlarged, and its utility correspondingly increased.

.In accordance with this invention a standpipe 1s provided near its outlet end with a circumferential seat or lip, upon which is supported a revoluble ring, which, in turn, is held against displacement by a nut. A shell is connected with a collar which is fitted in the upper end of the stand-pipe, and the whole bolted together. A rotatable plug is arranged in the outlet of the shell and a-delivery nozzle is provided, and adjacent to said plug the shell is constructed with a clearance chamber extended laterally from said inlet around the Serial No. 479,235. (No model.)

on the irregular section line -.r Fig. l;

Figs. 3, 4 and 5, details to be referred to.

. Referring to the drawings, A represents a suitablestand-pipe of desired size, the same in the present construction being provided at a short distance from its upper end withacircumferential seat or lip et upon which rests the revoluble ring a. retained in its position upo`n the said circumferential lip bv a ringnut a? threaded upon the upper end of the stand-pipe.

The upper end of thestand-pipe is counter-bored for a short distance to receive the gland h depending from the collar b', said collar at its vupper end receiving the shell O of the device, said shell in the present instance having its neck c tapped into the said collar as shown in Fig. 1.

A packing c is introduced between the collar b and the end ofthe stand-plpeA to render the joint between the two perfectly tight, yet permitting one to be revolved upon and with relation to the other.

The ring a', see Fig. 3, is provided with tw diametrically opposite ears a3, a4, through which respectively are passed bolts atapped into suitable bosses upon the shell U, and by means of which the said shell may be drawn down to compress the packing c andl render tight the joint between the revoluble collar b and the stand-pipe. The said ring a. is also provided with two diametrically opposite ears a6 located intermediate of the ears a3, a4, and through which respectively are passed bolts a7, one of which is shown in dotted lines Fig. l, which bolts are tapped into ears b2 formed on the collar b', see Fig. 4, the said bolts a7 furnishing additional means by which to draw the parts tightly together.

A rotatableplug or valve D is mountedin the shell C, the bearings d for the said plug being located at or near the ends of the latter, as best shown in Fig. 2.

The plug D is provided with a centrally located outlet opening or passage d into which at one end, as shown, is tapped the butt end of the nozzle d2 of usual or desired shape or construction, the said nozzle protruding through a slot-like opening c2 in the shell C, see Fig. 1.

.In accordance with the principal part of this invention the inlet c3 for the shell C is provided with a laterally extended clearance space or passage c4 which extends to one side of or laterally from the said inlet around the periphery of the plug D between its end bearings and in the plane of the outlet in order to permit the said plug to he rotated through more than ninety degrees, and yet always provide a free communication between the opening d therein and the inlet c3 of the shell. For example, the plug may be turned into a vertical position and have an almost straight communication between the nozzle and the inlet c3, and from this vertical position it may be turned down toward or into a position at least ten degrees below horizontal, as shown by dotted lines, communication still being had between the nozzle and the said inlet opening by means of or through the clearance space c4. Were this clearance space omitted and the inlet c8 carried directly to the bore or seat in the shell,it would be i-mpossible to rotate the plug d for any distance, without carrying the opening in the plug past the entrance to the inlet c3, and thereby cutting olf the inlet as the conical plug in a usual valve operation to cut off communication to the pipe in which it is placed.

As previously referred to, there is a limit to theenlargement of the opening in the plug owing to the size of the plug, but by making the opening iii the plug of its usual normal size and providing a clearance extendinglaterally from the entrance inlet around theoutside of the plug, the latter may be turned to a considerable'distance past the actual entrance to the inlet, and yet provide a free and full communication from the said inlet to the said opening through the clearance. v This clearance may be extended to one or both sides according to the particular range it is desired to give to the nozzle d2.

In practice the plug will be provided with suitable means, as for example the handle h, by whichV it may be rotated to change the direction in which the nozzle points, and the entire shell carrying the nozzle wit-h it may be rotated freely about and upon the standpipe A. The plug is drawn into its seat in .the shell by suitable means or devices, I having herein shown a plate c5 applied to the shell through which is extended a central lug d3 on one end of the plug, the said lug being threaded to receive a nut d* between which and the said plate c5 is interposed a suitable washer as d5. By this means the plug may be drawn tightly to its seat to prevent leakage, yet the plug may be readily removed.

I claim- 1. In a nozzle, a stand-pipeA provided with a circumferential seat or lip a, the rotatable ring a', and nut a2 therefor, the collar b and shell carried thereby, the bolts a5 anda", the

' rotatable plug and the nozzle carried thereby,

all constructed and to operate substantially as described.

2. The combination of a stand-pipe provided i with a circumferential seat or lip a, the rotatiable ring a', nut a2, collar b', shell C mounted i in said collar and havingan inlet and an outlet, bolts a5 and a7 for connecting these parts,

and a rotatable plug arranged in the outlet WILLIAM K. CRAWFORD.
