IMPROVEMENT IN HYDRANTS.

Specification forming part of Letters Patent N0. 57,449, dated August 21, 1866.

To all whom it may concern:

Be it known that I, JAMES M. WARD, of the city, county, and State of New York, have invented a new and Improved Hydrant; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the 'art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a vertical section taken in the line y y, Fig. 2; and g. 2 is ahorizontal section of my improved hydrant, taken in the line w x, Fig. 1.

Similar letters of reference in the different figures indicate corresponding parts.

rlhis invention relates to new and useful improvements in hydrants whereby a hydrantis produced which is simple and efficient, and is not liable to get out of order, as hereinafter set forth. Y

The upper portion, A, of the pen-stock is formed in a separate piece, and is bolted to the lower part, A', as shown, by bolts n n, Fig. l, a diaphragm, Z Z, being bolted in between the parts A A of the `enfstock at the same time. Upon this diaphragm l is laid a rubber packing gasket or ring, j, which is pressed down by screws and aring, It, so that the rubber j is compressed snugly around the valverod E, and making a water-tight jointaround the same, and thus the water is contlned to chamber I and below diaphragm ZZ when it is admitted int-o the pen-stock.

E is the valve-rod, and F is a valve fixed on the lower end of the same. A top view of the valve F is shown in Fig. 2, it having an open space, m fm, upon either side of it, and in one side has a groove which travels on a guiderib, f, which projects from the inner surface of the pen-stock A.

h, Fig. 1, is the induction-port, and i is the escapeport. g, at thef-bottom, is a wasteport.

The upper end, e, of the valverod has Wa screw-thread cut thereon which engages with a nut, D, the said nut D having a handle, d,

and is held in place by a diaphragm, r r, which engages with a groove in the nut D. a ais a cover which is hinged to the penstock at I), as usual, and carries a short shaft, O, having an arm, c.

Its operation is as follows In the position of valve F, as shown in Fig. 1, the hydrant is delivering water. The valve F being down so as to uncover the inductionport h, water enters and passes up through chamber I and out of the delivery or escape port t'. .When the valve E F is elevated by the nut D so that the valve F closes the induction h, then the entrance of the water is cut off, and at the same time the waste-portg is opened, and the water remaining in I is allowed to waste through the said port g, so that the hydrant is empty when-not in use, and is not liable to be frozen up and become inoperative from such cause. The waste-waterin escaping past the valve F passes down the open spacesm m, Fig. 2, upon either side of the valve E, and thence into the waste-port g, when the valve F is elevated to cover the induction.

For raising or lowering the valve-rod and valve the cover ct is thrown back and the elevating-nut D is turned by the handle d. The short shaft G and arm c secure or fasten the cover ct down, the arm c being turned so as to catch under the lip a', Fig. 1.

By these means I produce a hydrant which is simple in operation, and which is not liable to get out of order.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

The sliding valve F E, elevating-nut D d, diaphragm Z Z j 7c, and portst' h guarranged and operating substantially in the manner and for the purpose set forth.

The above specication of my invention signed by me this 3d day of April, 1866.

JAMES M. WARD. c
