SPRINKLING APPARATUS SPECIFICATION forming part of Letters Patent N 0. 479,979, dated August 2, 1892. Application filed January 5 189l- Serial No. 376,696. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE S. GLENN, a citizen of the United States, residing at Nashville, county of Davidson, and State of Tennessee, have invented certain new and useful Improvements in Sprinkling Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in sprinkling or flushing apparatus designed particularly for use in sprinkling or flushing the streets of a city or town, though the invention is, as will be apparent, capable of use for a variety of other purposes.

The invention consists in certain improvements in the construction and arrangement of the sprinkling-pipes and also in an improved construction and arrangement of sprinkler to be used in connection with such pipes, all of which will be hereinafter fully described in connection with the accompanying drawings, in which- Figure 1 is a perspective view of a street the sidewalks of which upon opposite sides of the roadway are equipped with the sprinkling apparatus of the present invention. Fig. 2 is a plan view of a square the four sidewalks of which are similarly equipped. Fig. 3 is a side elevation, upon an enlarged scale, of one form of sprinkler. Figs. 4 and 5 are similar views of two other forms of sprinklers.

Referring to Figs. 1, 2, and 3, it will be seen that the sprinkling apparatus of the present invention, which is therein illustrated as applied to the sidewalks of a city street for sprinkling the roadway between them, con sists of a pipe A for each sidewalk B, arranged longitudinally thereof and located beneath the flagstones, as shown by dotted lines, Fig. 1, at ashort distance from the curb 0. Each pipe A is connected by a pipe D with the service-main E or with any other source of watersupply, and each pipe is provided at regular intervals in its length with a plurality of sprinklers F, the construction of which will presently be described, which project outwardly from the pipe A to within a short distance of the outer face of the curb C. At the points in the curb coinciding with the sprinklers F suitable openings or recesses are formed for receiving the sprinklers, which openings or recesses are of a depth sufficient to permit the outer face of the sprinklers when the latter are in position therein to lie within the outer surface of the curb, and thus be out of the way of passing vehicles and the like, the contact of which with said sprinklers would be liable to break or otherwise damage the latter. The number of sprinklers F with which the pipe A is provided will be dependent, of course, upon the length of such pipes, these sprinklers being so positioned relatively to each Other that the jet or stream from each will meet or perhaps overlap the jet or stream of the contiguous sprinkler, and thus insure a uniform, and consequently a more rapid, flushing or sprinkling of the roadway. Each pipe A,in addition to its supplypipe D, is provided with a waste-pipe G,co1nmunicating with a sewer, cistern, or other point, and between the supply and waste pipes there is located a two-way cook or valve H, which in one position opens communication between the supply-pipe D and sprinkling-pipe A and closes communication between the latter and its waste-pipe G, and in its other position closes communication between the supply and sprinkling pipes and opens communication between the latter and its waste-pipe, so as to permit the escape of the water still remaining in the sprinklingpipe after the closing of the supply, and thus prevent freezing of the latterin cold weather. The stems of the valves or cocks H extend upward through the flagstones into hand-holes I, provided therein for receiving them, and thus positioned they are readily accessible and at the same time out of danger of breakage, 850., by the feet of pedestrians.

Referring now particularly to Fig. 3, the construction of the sprinkler therein illustrated will be described. The sprinkler F therein shown is connected bya neck f to the pipe A and projects outwardly through the curb Oin a slightly-inclined upward direction, as shown. The face of the sprinkler is convex and the lower half thereof is provided with a plurality of perforations so positioned therein that the water issuing therefrom will spread radially outward toward the center of the roadway, the jets or streams issuing from the end perforations in lines which intersect the jets or streams issuing from the contigu- ICZO ous sprinkler. The supply to each pipe A should be so regulated that the pressure of the water will be of sufficient strength to throw streams or jets from the sprinkler to the middle of the street or as far as may be desired.

The pipes A of Fig. 1 and those of the square illustrated in Fig. 2 are shown as hav ing each an independent connection to the source of water-supply and an independentwaste connection, and this arrangement is the preferred one for the following reason: It will often happen thatthe roadwayof one street will require sprinkling or flushing more frequently than the roadways of the other streets, and at times when the sprinkling or flushing of the roadways of the other streets would be a waste of the water, and it is necessary in order to prevent such waste that the sprinkling of the one street maybe carried on independently of the others. This is secured in the present case by the provision of the independent connections described for each pipe with the water-supply. lVhere, however, it is not desired to provide for such independent sprinkling or flushing, the four pipes, or any number of the pipes of the square, may have a common connection to the supply. As shown, the pipes of each square are independent of those of the other squares; but it will be apparent that the pipes of all or any selected number of squares may have a common connection to the supply, if desired. What has heretofore been described as the preferred form will, however, in nearly all cases be found most advantageous.

The operation of the apparatus is as follows: When it is desired to sprinkle or flush any selected street, all that it is necessary to do is to turn the cocks Ii upon opposite sides of the street and put the two pipes A into communication with the main E. The water will then issue from the sprinklers F upon opposite sides of the street, the streams or jets from one side meeting or lapping those from the other and the streams or jets from one sprinkler meeting or lapping the streams or jets from the contiguous sprinkler in the same pipe. To stop the flow of water, the valves H are turned in the opposite direction, shutting off the supply and opening communication between the pipes A and their wastepipes G, through which latter the water remaining in the pipes Ais drained, so as to prevent freezing of the latter in cold weather.

The construction of sprinkler illustrated in Fig. 3 will be found adapted in most cases to the securing of the proper throw of water to insure the sprinkling of the middle of the roadway; but it will sometimes happen that the head or force of the water-supply is not sufficiently strong to insure this long throw with such sprinklers. To meet such conditions, the apparatus may be provided with J sprinklers of the construction illustrated in Figs. 4 and 5. The sprinklers shown in these figures are connected to the sprinkling-pipes and are upwardly inclined the same as in the preceding figures. They are, however, made of thicker metal and are provided with openin gs 0, which taper outwardly toward the face of the sprinkler, the outer edge of each opening being considerably less in diameter than the inner edge, as shown. With the openings thus tapered the pressure of the water there in is increased to such an extent that the water issuing from the sprinklers, even where the head is very light, is thrown in thin jets or streams with great force into the center of the roadway.

It may be necessary or desirable in some uses to which the sprinkling apparatus of the present invention may be applied to clean the interior of the sprinkler of dirt or sediment which may have collected therein and which cannot well be removed by the water. To provide for such cleansing, the upper unperforated half of the sprinkler is hinged upon the lower half, as shown in Fig. 5, and ready access can be had to theinterior of the sprinkler by swinging the upper half back upon the under half, so as to expose the interior of the sprinkler, from which such dirt or sediment can then be removed by hand or otherwise. When the cleansing of the sprinkler is completed, the hinged portion of the sprinkler is swung back to its closing position, the meeting edges of the two portions formingawatertight joint and locked in that position by any suitable means.

As I have before intimated, the apparatus of the present invention is capable of application to a variety of purposes other than the single one illustrated-as, for example, to the sprinkling of vineyards,lawns, gardens,farms, race-courses, &c.and all such other applications of the apparatus are included in the present invention. In such other applications the sprinklers may be arranged as shown in Figs. 1 and 2, or as shown in Fig. 6, and they may consist, as shown in the latter figure, of a number of sliding sections or of a single pipe of a height suited to the particular purpose to which the apparatus is applied.

That I claim is 1.. In a sprinkling apparatus, the combination of a pipe arranged along the surface to be sprinkled, connections between said pipe and a source of water-supply, and a plurality of convex-faced sprinklers in said pipe projecting above the surface to be sprinkled and provided with outwardly-tapering openings upon their lower portions to throw the water downwardly and unperforated upon their upper portions, the two portions of the sprinkler having a hinged connection to each other, substantially as described.

2. The combination, with pipe A, of the sprinkler F, connected to said pipe and inclined upwardly and toward the surface to be sprinkled, the lower portion of the face of said sprinkler being perforated and its upper portion unperforatcd, the two portions of the sprinkler having a hinged connection to each other, whereby access may be had to its interior, substantially as described 3. In a sprinkling apparatus, the combination of a sprinkler the face whereof is made in two parts having a hinged connection to each other, whereby the interior of the sprinkler may be exposed for cleansing, one of said parts being perforated and the other unper- 1o forated, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
