SPECIFICATION forming part of Letters Patent No. 436,942, dated September 23, 1890.

Application filed February 10, 1890- Serial No. 339,876. (No model) To to whom it may concern:

Be it known that I, THOMAS SCHEEN, a citizen of Norway, residing at St. Helena, Napa county, State of California, have invented an Improvement in Lawn Sprinklers; and I hereby declare the following to be a full, clear, and exact description of the same. 1 My invention relates to a novel lawn-sprink- It consists of a short cylindrical head adapted to screw upon the end of a nozzle or any supply-pipe, and having a peculiarlyformed slot extending outwardly from a central opening to the periphery of the sprinkler.

Referring to the accompanying drawings for a more complete explanation of my in vention, Figure 1 is a sectional view of one of my sprinklers, showing its attachment to an ordinary nozzle. Fig. 2 is a horizontal section taken through the sprinkler and in the plane of the discharge-slit. Fig. 3 is a section showing the plane of discharge at right angles with the axis. Fig. 4 shows a former for the discharge-slit.

A is the body of the sprinkler, which is made in any suitable or desirable form, either as a short cylinder closed at the outer end, which end is at right angles with its axis, or the closed end may be, as shown in Fig. 1, at an angle of thirty-five degrees, more or less.

In the center of this sprinkler is a screwthreaded opening-D, adapted to fit upon the end of any suitable or convenient nozzle or pipe 0. From the bottom of this hole a wedgeshaped slit E extends outwardly to the periphery. This slit is made thinnest where it connects with the interior opening, and gradually diverges, so that it is widest at its periphery upon the outside. It is also made diverging toward the sides of the slit, extending from the central opening of the sprinkler to the periphery. At the central opening the sides of the slit meet at points which will intersect a line drawn through the center of this opening, as shown in dotted line, Fig. 2. This gives an area of surface to be covered by the sprinkler of any desired degree, and the peculiar shape of the slit, being narrowest and thinnest at the interior and gradually diverging and becoming wider toward the periphery, produces a fine delicate spray, which under a light pressure is like afine rain, and under a hard pressure becomes an extremelyfine mist. The slot maybe made to suit any pressure and to throw any desired volume.

It will be manifest that the end of the sprinkler may be made at any desired angle; but I have found the angle shown in the present case to be very satisfactory.

Upon the opposite side of the sprinkler from the discharge-slit is made asmall hole F, into which a pin projects from a supporting-board, or the pin may be made so as to be simply pressed into the earth, and thus support the nozzle and sprinkler in proper shape to throw the water, as desired.

It will be manifest that this sprinkler may be equally well used as a hand-sprinklerwhen desired.

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

1. In a lawn-sprinkler, the cylindrical head having a closed end and central opening adapted to be fitted to the nozzle, said head having a slit extending outwardly from the bottom to the periphery and being made widest at its outer end.

2. In a lawn-sprinkler, the cylindrical head having a closed end and central opening adapted to be fitted to the nozzle, said head having a wedge-shaped slit extending outwardly from said opening toward the periphery and being widest at said periphery and having also its end walls diverging, substantially as described.

3. A lawn-sprinkler consisting of thecylindrical head having the central opening adapted to fit the nozzle and the closed outer end at right angles to the axis, a slit made through the side of the head, connecting the central space with the periphery upon diverging and widening lines, a hole made in the side of the head opposite to the slit, and the pin upon which the head is supported, substantially as herein described.

In witness whereof I have hereunto set my hand.
