CHARLES L. STACY, OF CINCINNATI, OHIO.
HYDRANT.
Specification forming part of Letters Patent No. 25,683, dated October 4, 1859; Reissued June 6,
T o all whom it may concern:
Be it known that I, CHARLES L. STAcY, of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvenients in Hydrants, and do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.
My invention relates to that class of hydrants in which a provision is made for emptying the discharge pipe whenever the hydrant is closed, and consists in a peculiar arrangement of chambered plunger having two cupped leather pistons, said chamber having intermittent communication with the drip-hole and continual communication by means of a small aperture with the discharge ipe.
p The form of the chainbered piston and its relation to the drip-hole and aperture leading from the discharge pipe is such that water pressure immediately on the opening of the hydrant is communicated to the lips of the cupped pistons which presses them to the sides of the cylinder and prevents escape of water either by the drip or mouth of cylinder.
In the accompanying drawings, Figure 1 is an axial section of the hydrant when closed and Fig. 2 the saine when open. Fig. 3, is a perspective view of the plunger.
A is the hydrant cylinder, B and C the receiving` and discharging pipes respectively. The end B of the receiving pipe acts as a valve seat.
D is a box to which the hydrant rod, and plunger shank E are attached at its upper and lower extremity respectively.
F F F are disks of leat-lier forming the upper piston. Cr G Gr Gr" are similar disks of leather forming the lower piston, the disks G G being cupped.
H is a distance piece or sleeve separating the two pistons and forming the chamber.
Gm is a disk of leather forming the face of the valve and adapted to be readily renewed when worn.
The piece H can be made nearly the size and shape of the cylinder A and cups F, G so that the chamber I may contain as little water as possible and thus reduce the amount of wastage. The disks F, Gr, and G" are cupped as shown to form elastic pistons their lips 7, g, g', being calculated to receive the pressure of the water, immediately on the rising of the plunger for a discharge rendering the pistons perfectly tight so that no water can waste in discharging.
c J is a screw nut fitted to the shank E for tightening up the piston disks the sleeve H being free to slide on the shank.
K is a small hole connecting the discharge C with the chamber I and communicating the pressure of water to said chamber and to the piston cup lips f, g, g, while discharging.
L is a small hole drilled at such a height in the cylinder A as to be immediately above the cup G when the hydrant is closed. It is termed the drip and is designed for the purpose of carrying off the water contained in the pipe C and chamber I after discharge of water so that no water may be left in the discharge pipe C liable to freeze up. The water flowing through the aperture L may either be conveyed into a reservoir or allowed to escape into the ground the quantity being too small to cause serious inconvenience. rIhe drip L being immediately above the top of cup G when the hydrant is shut off becomes instantly and completely closed upon the opening of the hydrant in the raising of the plunger, the cup G covering it as seen in Fig. 2. The lips f, g, 9, at the same time receive ing the pressure of water from the pipe C through aperture K are pressed tightly to the sid-es of the cylinder and entirely prevent any waste of water while the hydrant is open either by the cups G Gr" to the drip or by the cup F to the top of cylinder A. The piston admits of being taken out bodily at will, without disturbing the other portions of the hydrant.
Gum elastic or other suitable material may obviously be substituted for leather in the construction of the piston.
I claim as new and of my invention- 'Ihe relative arrangement of the cup formed disks F G and G" and the apertures K and L adapted in the manner set forth to form a chamber I closed on all sides (with the exception of the ingress aperture K) while the hydrant is open for the purpose of expanding the flanges f and g, and upon the closing of the hydrant to uncover the aperture L and thereby empty the discharge pipe C.
In testimony of which invention, I hereunto set my hand.
