LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 510,496, dated December 12, 1893. f I Application filed $eptemher 29,1893- Serial No. 486,323- (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES ANDERSON, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Lawn-Sprinklers; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a new and useful improvement in lawn-sprinklers, and has for its object, more especially, a sprinkler for distributing the water in the form of spray upon the lawn, the sprinkler being operated by water pressure.

It is also the object of my invention to provide an improved sprinkler whereby the wa- 'ter may be sprayed either in a circle or only at one side, as in the form of ahalf-circle, the device being arranged so that the water may be sprayed on either side desired,alone, or upon both sides as may be desired.

To these ends myinvention consists of the combination of devices and appliances hereinafter specified and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a vertical section, showing the blades and spindle in elevation. Fig. 2 is a plan view. Fig. 3 is a side elevation showing the sprinkler engaged with an improved support, and Fig. 4 is a vertical section showing a modification of my invention, the blades being shown in side elevation.

My invention is designed to provide an improved sprinkler of superior simplicity and economy of construction, which shall be at the same time less liable to get out of order and of greater efficiency than similar devices heretofore in use.

I carry out my invention as follows:

In the drawings A denotes a suitable casing provided with an attaching arm A whereby the sprinkler is engaged with a hose B. The top of the casin g A is provided with openings indicated at a. I have shown four of such openings in Fig. 2 but any suitable number of such openings may be employed, as may be desired.

A denotes an interior diaphragm dividing the interior of the casing A into two chambers A and A, openings a communicating with each of said chambers. In Fig. 2 the diaphragm is shown by dotted lines.

The diaphragm A is constructed with an orifice as at a, communication through which is controlled by a valve or screw 0, extending to the exterior of the casing A. It will be perceived that when the orifice a is opened, water will pass out of the hose into both of the chambers A and A and will thence pass outward through the orifices a in the top of the casin g and against the rotatable blades 0 whereby the water will be sprinkled in a circle upon the lawn. Should the valve a however, be closed, the water would pass from the hose only into the chamber A and would strike upon only one side of the blades 0 and would therefore sprinkle only upon one side of the casing A, as in the form of a half I circle.

The blades G are preferably four in number, of suitable form to be propelled and rotated by the pressure of the water striking against their under surfaces, either when the water is emitted from both chambers A and A, or from only one of said chambers. The blades are rotatably mounted upon a stem c engaged in the top of the casing A. In the form shown in Fig. 1, it will be evident that when the water is closed off from the chamber A, the water would be sprinkled on the opposite side of the diaphragm A or on the side. of the arm A. With asprinklerof this construction, should it be desired to sprinkle the lawn in the opposite direction, it would only be necessary to turn the sprinkler about, the arm A being located upon the opposite side of that shown in Fig. 1. This could readily be done by simply taking hold of the hose and turning it about in the opposite direotion. In Fig. 4, however, I have shown a modification in the construction of the sprinkler whereby water may be discharged on either side without the necessity of moving the hose. This may be accomplished by the provision of the additional diaphragm A in the chamber A formed with an opening a controlled by a valve or screw a reaching to the exterior of the casing.

WVith a sprinkler as illustrated in Fig. at, should it be desired to sprinkle thelawn upon only the side of thearm A, the valve a would be closed and the valve a opened. Should it be desired to sprinkle only on the side Opposite the arm A, the valve a would be opened and the valve 0. would be closed. Obviously the adjustmentof the valve a where a single valve is employed, or of the valves a and 6%, when two valves are employed, is a very simple matter and there is no liability, whatsoever, of the device getting out of order.

With the construction illustrated in Fig. 4, should it be desired to sprinkle the lawn in the form of a circle, both of the valves or screws would be opened.

I do not limit myself to any particular construction of the rotatable blades 0.

D is a stem, whereby the sprinkler may be fastened in place upon the lawn.

A further object of my invention is to provide a novel support for the sprinkler, which I have shown in Fig. 3. The support consists, essentially, of a central hub E made to receive the spindle D and provided with a set screw d to hold the spindle in place. Connected with the hub are radial arms D provided with casters d at their outer extremities. The arms D are made of suitable length to prevent any liability of tipping over in changing its position. The sprinkler being thus mounted upon the support, above described, may readily be changed in position by simply taking hold of the hose and pulling the sprinkler to any desired point without the necessity of shutting off the water. With such a support, the sprinkler can be readily and conveniently moved from place to place without the liability of the operator being wet or being obliged to shut off the water.

My improved sprinkler may, however, be used with or without the improved support herein shown and described.

To prevent the valves becoming disconnected from the casing, and thus being liable to be lost, the adjacent portion of the casing may be kerfed and upset toward the stem of the valve as shown more particularly in Fig. 1 at a It will be seen that the rotatable blades are centrally mounted on the top of the casing A and their position needs no changing to throw the water to one side alone, or the other, as may be desired. hat I claim is- 1. In a lawn sprinkler, the casing communicating with the water supply and constructed with outlet orifices, the diaphragm located within the casing and dividing the interior of the casin g into communicating chambers, and the valve to control said communications, substantially as set forth.

2. In a lawn-sprinkler, the combination of the perforated casing, the rotatable blades connected therewith, a diaphragm located within the casing provided with an orifice dividing the interior of the casing into chambers communicating through said orifice, and the valve to control said orifice, substantially as described.

3. In a lawn-sprinkler, the combination of the casing, rotatable blades mounted on a supporting stem engaged upon said casing, a diaphragm dividing the interior of the casing into communicating chambers, a valve to control said communications, and the support for the casing, said casing provided with out-let orifices opening into said chamber beneath said blades, substantially as set forth.

4. In a lawn sprinkler, the combination of the casing provided with out-let orifices, a diaphragm dividing the interior of the easing into communicating chambers having inde pendent orifices, a valve to control said communication, means to hold said valve from displacement, and rotatable blades mounted upon said casing above said out-let orifices, substantially as set forth. i

5. In a lawn-sprinkler, the casing A provid ed with interior diaphragms A and A dividing the interior of the easing into chambers A and A independently communicating with the chamber A valves to control said communications, and rotatable blades mounted upon the casing provided with out-let orifices underneath said blades, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
