Application filed January 2,
To all whom it may concern: 7
Be it known that I, WILLIAM KELLY, a citizen of the United States, residing at Memphis, Shelby county, and State of Tennessee, have invented and discovered certain new and useful Improvements in Drains for Water Systems, of which the following is a specification.
My said invention consists in an improved form of drain adapted to be inserted in a pipe line leading to hydrants, or like places in Water systems and has for its object to drain and collect the water remaining in the pipes above the point of connection, or above the freezing point, when the water supply is turned ofi, whereby freezing and consequent damage to the system is avoided.
A further object is to provide means whereby the water collected in the drain device is forced out through the discharge pipe when the water is again turned on and the water collection receptacle thus emptied and made ready to receive the water drained from the pipe line when the supply is again turned off.
Said invention consists further in the par ticular construction and arrangement of various parts whereby attachment may be readily made to hydrants and other parts of water systems with which it is to be employed.
Referring to the accompanyingdrawings, which are made a part hereof and on which similar reference characters indicate similar parts,
Figure 1 is a vertical section of my improved drain device as connected in' a pipe line, and
Fig. 2 a vertical section showing a modified form.
Said improved drain device consists of a cup-shaped fitting or body A adapted to be connected in the water supply line 6 and 10 contracted in size from its connection with the pipe 6 to its upper end. The end of said nipple is exteriorly tapered from a point 9 to its point. A cap 3 end of the body A b screw-threaded flange 4, which screws onto the upper end of said body A. Said cap is formed with a nozzle section extending both ways therefrom, the part 12 extending within the cap being formed with a cu -shaped receiving end 11, and the through a device Specification of Letters Patent.
is connected with the upper y means of an internally Patented Feb. 20, 1917. 1-914. Serial No. 809,916.
above the cap being formed with a discharge orifice 7 which tapers or increases in diameter gradually from its connection with the part l2 'to its discharge element for the water system.
Arranged alongside the body A and at a lower level than said body, is a drain receptacle 16. A pipe 17 leads nearly to the bottom of said receptacle l6 and is connected y sections 14 and 15' with an aperture in the side of-body A, the connection being at a point below the upper end of nozzle 10.
In operation, as will be readily understood, the force of the water discharging from nozzle 10 into the orifice 7 through the receiving cup-shaped end 11 of said orifice will cause .a suction through the pipe composed of the sections 14, 15, and 17, and will draw the water from the receptacle16 and also from the lower part 2 of receptacle A, surrounding said nozzle 10. The contraction of nozzle 10 will cause the water to be ejected therefrom under pressure and the expansion of the stream in passing through the nozzle 7 will maintain said suction sufficient to keep theseparts practically empty and create a partial vacuum therein. Immediately on turning the water ofi at the hydrant by a valve (not shown) in pipe 6, the water remaining in pipe 8 andnozzle 7 discharge end leading into the p pe 8, which leads to the hydrant, or other will settle back into body A and through the tions are made in a single piece instead of in several parts as in Fig. 1. The nozzle 5 corresponds with the nozzle 10 in the prin cipal construction, the body 1 with the body A and cap 3 and parts formed thereon, and the pipe 15 with the pipe composed of the sections 1 1, 15, and 17 in the principal construction.
The operation is the same as that of the principal construction, as will be readily understood.
h Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:
A drain device for pipe-lines of hydrants or the like comprising a receptacle interposed in said pipe-line below the freezing line and provided With a vacuum chamber, a conical nozzle formed integrally with said receptacle in communication With said pipe-line and connecting said receptacle on one side and projecting into the vacuum chamber, a cap screw-threaded on said receptacle and formed With a nozzle section extending in opposite directions, one part of said nozzle extending above the cap and formed with a discharge orifice of increasing diameter from its connection With the cap to its discharge outlet, and the other part of said nozzle extending Within the cap and formed with a conical orifice extending Copies of this patent may be obtained for the freezing five cents each, by addressing the Washington, D. C.
downwardly and partially inclosing said the bottom of said drain receptacle, whereby the water drained from said pipe-line above line When said hydrant is out of use is siphoned back into the pipe-line when the hydrant is again brought into use, substantially as set forth.
In Witness whereof, I have hereunto set my hand and seal at Memphis, Tennessee, this 5th day of December, A. D. nineteen hundred and thirteen.
