JOHN W. MURPHY, OF BALTIMORE, MARYLAND.
IMPROVEMENT IN HVDRANTS.
' Specification forming part of Letters Patent No. 130,233, dated August 6, 1872.
Specification describing an Improved Hy.- drant, invented by JOHN W. MURPHY, of Baltimore, in the county of Baltimore and State v A represents the hydrant, B the box there-- of; (J, the plunger; D,'the cylinder; E, the chamber that receives water from main; F, the valve; f, a grooved cap connected by stem b to the valve F; G, the valve-seat; and H, the valve-closing spring. I is a side-slotted converging tube in center of plunger, through which passes the water, and from which it is discharged. This is fast to and moves with the plunger 0. K is a rubber packing inserted between the cylinder D and an adjustable cap, L, which is clamped thereto by screws 1. M
v is the pipe which connects the chamber E with the water supply 'or main. The plunger 0 is a hollow cast-iron cylinder, into which the tube I is screwed. The wear upon it, as well as that upon the packing K, is taken up by clamping down the screws 1 lmore tightly.
This packing will thus last a long time. N is the flange on bottom of hydrant, by which it is fastened in its box B. This is provided with screw-holes n n. It will be observed that the flange is arranged diagonally across the bottom, and not in line with pipe M, whereby the screws are not inserted in the same line of the grain of the wood and will not split the box.
The operation is as follows: The water from main comes through pipe M into chamber E, and, when the plunger 0 is pressed down so as to unseat valve F, rushes up into cyllnder D, thence through tube I, and finally through the outlet. As soon as the pressure is removed from plunger the spring H seats the valve and restrains the flow of water.
Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-
1. The spring-retracted plunger 0 having central discharge-tube I the valve F, stem 1), and grooved cap f, in combination with the cylinder D G, all constructed and operating in the manner and for the purpose specified.
2. The end-perforated flange N arranged diagonally across bottom of its box B, as and for the purpose described.
To the above specification of my invention I have signed my hand this 27th day of May,
A. D. 1872. a
