IMPROVEMENT IN HYDRANTS'.
To all whom 1t-may concern Vmarked thereon.
The object of my invention is to prevent water from freezing in the discharge or exhaust-pipes of hydrants, and consists in attaching to'a hydrant, beneath its water-way, a drain-chamber, provided with a Watertigbt sliding bottom, or piston-head and rod, and so arranged, that as soon as the piston-rod is released l from above, the weight of water ou the sliding bottom, or piston-head, Vcauses it to sink, thereby closing the supply-valve, and draining the water remaining in the discharge-pipe down into the drain-chamber, where it remains until the piston-rod is again raised.' By this arrangement,water never stands in the hydrant above that in the water-way, which being placed in the ground below freezing-point, prevents it from freezing therein.
rlhe accompanying drawings represent vertical sectional views of a hydrant embodying my improvement.
Figure 1 represents a vertical sectional view of my improved hydrant, showing-the sliding bottom, or piston-head of the drain-chamberup', the drain-ohamber empty, the supply-valve open, and.: the water passing through it and the delivery-pipe.
Figure 2 represents a similar view of the hydrant, with the sliding bottom, or piston-head down, the supply-valve closed, the delivery-pipe empty of water, and the drainchamber full.
Similar letters of referenceV indicate corresponding parts.
In figs. 1 and 2, A represents the supply-pipe, which is connected with the bottomless drain-chamber B, by the water-way C.
a is the inlet, Orsnpply-valve.
This valve is a wing-valve, andisheld in its seat by the spiral spring b, in the chamber c, operating against its head, as shown, and is guided by its wings, and by its head, the diameter of which is exactly the same as that of the chamber c, in which it operates.
D is the sliding bottom, or piston-head, which Vis packedso as to be Water-tight. l
E isthe piston-rod, and also the discharge, or exhaust-pipe. Onthis pipe being drawn up by any7 suitable mechanical arrangement, thetop of the sliding bottom, or piston-head 1), strikes the tail -of the supply-valve a, and raises it up out of its seat, letting the water rush in through it from the supply-pipe A into the upper portion of the drain-chamber B, and from thence up through the discharge-pipe E. .On the piston, or discharge-pipe E being released, the weight of the water on top ofthe sliding bottom, or piston-head D, causes it to sink, thereby closing the supply-valve a, and drawing the water from the discharge-pipe E into' the drain-chamber B, where it remains until the discharge-pipe, or piston E is again raised.
Wings may be cast upon the chamber B, to enable it tobe .fixed in position without the use of screws, 85o.,
by sliding it into suitable grooves in its frame, or support.
What I claim as my invention, and desire to secure by Letters Patent, is- Y 1. In a hydrant, the drain-chamber B, placed below the water-way G, as shown, and for the purposes herein set forth.
2. In combination with' a hydrant, as described,the water-tight sliding bottom D, of the chamber B, ar-
ranged as shown, and operating in the manner and for.
the purposes herein set forth. i
3. The arrangement of the drain-chamber B andextension-chamber c, so as to form, in combination with
