FlRE-HYDRANT'.

SPECIFICATION forming part of Letters Patent No. 655,781, dated August 14, 1900.

Application filed November 4, 1897.

Serial I To. 657,369. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT HUGHES, a citizen of the United States, residing at W'aterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Valves for Fire-Hydrants; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in lever-operating valves for fire-hydrants; and the objects of it are to construct a lever-operated valve which will at all times work parallel to a desired plane, to provide for the use of a single operating-nut or single operatinglever-end support, and to keep the downward motion of the gate when moving its seat as small as possible or to make the center of the gate keep in line with the center of the valve-opening at any position of the valve.

Figure 1 is a vertical section of the hydrantbottom, showing the valve closed and the stand-pipe attachedto the hydrant-bottom. Fig. 2 is a section of the hydrant-bottom,showing the valve open. Fig. 3 is a view of the lever attached to the operating-nut. Fig. 4. is a view of the arm attached to the station ary support. Fig. 5 is a top View of the gate. Fig. 6 is a back view of the gate. Fig. 7 is a vertical section of the gate. Fig. 8 is a top view of the sliding block. Fig. 9 is a back view of the sliding block. Fig. 10 is a side view of the sliding block.

Similar letters refer to similar parts throu ghout the several views.

The casing or bottom A is of suitable form to receive the mechanism of the valve and the valve. It is of sufficient size to permit the valve being removed through the top of it, and stand-pipe B, which is bolted to the bottom, has an internal diameter equal to that of the bottom. On the operating-stem C, which projects outside the cover D, is placed the nut E, which can be readily turned, by means of a suitable wrench, to operate the valve. The lower end of the stem is screwthreaded for operating the nut F. The lower portion of the stem works in a step in the bottom of the casing, and on the lower end of the stem is a non-actuator lever-end support T, in which the stem is free to revolve and which is attached at one end of the lever J by the pin T. The other end of the lever J is attached to the sliding block M by means of the pin M. This piece M is ar ranged so that it slides in a slot P in the back of the gate. The lever K is fastened at one end to the nut F by the pin F, the other end being fastened to the lug N on the back of the gate by the pin N. The levers J and K are pivoted together by the pin B. When the valve is drawn out from its seat, the valve is kept parallel with its seat by the piece M, working in the slot P on the back of the gate, and the levers being pivoted together at R. The piece M, working in the slot P, reduces the downward travel of the valves to a minimum, and when the levers are pivoted to= gether at R half-way of their length there is no downward travel of the valve.

In other arrangements used fora valve operated by a stationary lever attached to the lower end of the stem and having another lever operated by a nut on the stem the valve is made to traveldownward to a much greater extent than where the lower lever is free to slide, at its end adjacent to the valve, freely upon the back of the valve, and the upper lever is pivoted stationary to the back of the valve. This moving of the valve-face across the seats tends to injure the valve and its seat. In my device this movement across its face is either done away with entirely or re-' duced to such a small amount as not to affect the durability of the valve or its seat. My device also has an advantage over those devices using two operating-nuts, as only one nut is required in my device and a shorter length of threaded stem can be used. I do not wish to limit myself to the upper nut or lever-end support being drawn up or down by a threaded screw, as any means of actu= ating it may be employed other than to have the stem threaded, as hereinbefore stated. I term the stem in my claims the lever-actw ator for the lever end support and the nut the lever-end support.

What I desire to claim as new and of my own invention is 1. In a hydrant-valve the combination of a casing, support and actuator for one leverend support, a non-actuator support for the other lever, valve to close the opening in the casing, levers crossing each otherand pivoted together between their ends and means for keeping the face of the valve parallel to the desired plane, and arranged to minimize the downward travel of the valve substantially as described.

2. In a hydrant-valve, the combination of the casing, support and actuator for one of the lever-end supports, stationary lever-end support for the other lever, levers attached to said supports and to the valve, a valve to close the opening in the casing, said levers being pivoted together between their ends,

one end of one of the levers being pivoted to the back of the valve, and one end of the other lever attached to the back of the valve so as to freely move up or down relative to the back of the valve, substantially as described.

3. In a hydrant-valve, the combination of the casing, support and actuator for one of the levers, stationary lever-end support for the other lever, levers to operate the valve, a valve to close the opening in the casing, the stem being free to revolve in the lower leverend support substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
