SPRINKLEReHEAD.

SPECIFICATION forming part of Letters Patent No. 634,900, dated October 17, 1899.

Application filed Tulle 6, 1399. Serial No. 720,779. (No model.)

To all whom it Wtay concern:

Beit known that I, WILLIAM H. MILLER, a citizen of theUnited States, residing at the city of South Bend, in the county of St. Joseph 5 and State of Indiana, have invented certain new and useful Improvements in Sprinkler- Ileads, of which the following is a specification.

This invention relates to improvements in sprinkler-heads, and particularly toimprovements in sprinkler-heads for use on sprinklerwagons, though the structure is adapted for use in other relations.

The objects of this invention are, first, to

I5 provide an improved construction of sprinkler-heads which can be quickly closed and shut off; second, to provide a construction in which the spray can be partially cut off or deflected without stopping the action of the sprinkler when passing teams or persons on the street.

A further object is to reduce as far as possible the expense of manufacturing the sprinkler-heads of this class which shall be per- 2 5 fcctly effective.

Still further objects will definitely appear in the detailed description to follow.

I accomplish these objects of myinvention by the devices and means described in the specification.

The invention is clearly defined and pointed out in the claims.

The invention is fully illustrated in the accompanying drawings, forming a part of this 5 specification, in which Figure l is a detail view of my improved sprinkler head and operating-levers and means separated or broken away from the tank-wagon on which they are usually sup- 0 port-ed. Fig. 2 is an end elevation of the structure appearing in Fig. 1, taken from the left-hand end. Fig. 3 is a transverse sectional view on line 3 3 of Fig. 1. Fig. 4; is a longitudinal sectional view through the 5 structure appearing in Fig. 1, taken on line corresponding to lines 4: 4 of Figs. 2 and 3, a part of the levers and hangers being shown in full lines.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and

similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the main shell of a cylindrical sprinklenhead, which is connected by a collar K and hose K to a tank or other supply.

A tube or sleeve A extends axially from the opposite end, and to the outer end of this is secured a hanger rod or support by collar F and rod F and other hangers or rods L L are seen red to cars on each side of the collar K.

The shell A, which is. cylindrical in form, is provided with spray-perforations R, which are largest, on the sides so that the spray will be thrown farthest from these points, while directly underneath they are comparatively small. A transverse opening S is made through the lower side of this shell A toward its closed end to serve the purpose of whatis known as the washout for allowing the escape of any accumulation within the cylinder or shell A in cleaning the same.

A shell B is provided which fits over the outside of the shell A and corresponds thereto in dimensions and is reduced to a hub or collar B at the closed end, which fits over the tube or sleeve A, which serves as a guide for the same. Little pintles J project out on the sides of this shell B, and a forked lever H embraces the said pintles and extends upwardly and is secured to a portion of the framework G by a pin G, extending through the slot in the upper end. A rod I is connected by a pivot I to the lever H and passes to the footboard or other convenient place for manipulation to control the shell, pushing it in or out to cover or uncover the perforations R, or shut the same off entirely by pressing against the gasket 71, which is placed against the collar K. A similar gasket 01 is on the outer end of the shell A to form a water-tight joint at that point when the outer shell B is closed.

Extending through the tube A is a rock- 5 shaft 0, around which is a stufting-box E at the outer end of the tube A. This connects by suitable arms to a deflector-blade 0 within the shell A, (clearly appearing in Figs. 3 and 4,) the blade being curved and as long as the loo sprinkler-shell A and extending inside about one-third of the circumference of the shell entire space covered by the spray.

and fitting loosely within the same. A lever I) is provided on the outer end of the shaft 0 and is connected by a suitable rod D or sprinkler-head that the spray therefrom is under complete control, both as to quantity and direction. When a light spray is required, the shell B is drawn off from the main casing A but a little distance, when the light spray will be thrown to full width. If more spray is required, the shell is thrown still farther back, and so on, until all of the perforations are exposed. There is substantially no strain on the shell B, because all of the pressure is outward, and the same is manipulated with great ease, and very little pressure will be required to hold it in a closed position against the gasket n. 4

In passing along the street if it is desired to deflect the spray momentarily it is easily accomplished by swinging the deflector O downward by means of the connecting-rod D and lever I) until the spray is-defleeted or thrown down to the full extent desired. This also stops the free flow through the upper perforations, so that there is no m ore water allowed to pass than is required to sprinkle the This is of great advantage in that it enables the user of the device to pass a team or person on the street without shutting off the entire sprayhead, but merely controlling the spray as desired.

I am aware that my improved structure is quite effective without the use of this deflector, though the advantages of the deflector are indeed very great. It is also appropriate to remark that the deflector in this position could be used with other styles of spray-heads, though this particular deflector and particular spray-head operate together admirably to control the spray completely.

I desire to state that this improved sprayhead can be used in connection with a forcepump or with a tank or any other means for delivering the water thereto in a strong current and will be found effective in every way.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a cylindrical shell A, closed at its outer end containing spray-openin gs and connected bya suitable hose; hangers for supporting the same; a cylindrical shell conformed to said spray-cylinder and adapted to be moved over the same; and a gasket on the said shell or collar to receive the end of the shell for effectively shutting off the water or controlling the amount of the spray, for the purpose specified.

2. The combination of a cylindrical shell A, containing spray-openings and a slot on the under side for a washout connected by a suit able hose; hangers for the support of the same; a cylindrical shell conformed to said spraycylinder and adapted to be moved over the same; and a gasket on said shell or collar to receive the end of the shell for effectively shutting off the water or controlling the amount of spray, for the purpose specified.

In a spray apparatus the combination of a cylindrical shell containing spray-openings, means of delivering water thereto; a rockshaft extending into the same; and a curved deflector corresponding to the interior of the said cylindrical shell carried by the rock-shaf t to be swung over a portion of the perforations to control the spray and deflect the same, for the purpose specified.

4. In a spray-head the combination of the shellA,containing spray-openings,with a supply means connected to one end thereof, and a tubular extension at the opposite end; a cylindrical shell embracing the said shell A and adapted to reciprocate over it and embracing the tubular extension; a gasket against which the said exterior shell contacts in shutting off the water; a rock-shaft through the tubular extension and a curved deflectorblade secured to the rock-shaft to swing opposite a portion of the spray-openings to defleet the spray, for the purpose specified.

5. In a spray-head the combination of the shell A, containing spray-openings and a slot on the under side, with a supply means connected to one end thereof and a tubular extension at the opposite end; a cylindrical shell embracing the same and adapted to reciprocate over the said shell A and embracing the tubular extension; a gasket against which the exterior shell contacts in shutting off the water; a rock shaft through the tubular extension and a curved deflector-blade secured to the rock-shaft to swing opposite a portion of the spray-openings to deflect the spray, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
