NEIL MALMQVIST, OF BROOKLYN, NEV YORK.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 574,744, dated January 5, 1897.

Application'iiled December 12,1895. Serial No. 571,913. (No model.)

To all whom '1125 may coll/cern.-

Be it known that I, NEIL MALMQvIsT, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hydra-nts, of which the following is a speciiication.

My invention consists of improvements in hydrants whereby it is designed to simplify the construction, cheapen the cost, and improve the operation, as hereinafter described, reference being made to the accompanying drawings, in which- Y.

Figure l is a sectional elevation of my improved hydrant, the section being taken on line as it, Fig. 2. Fig. 2 is a sectional elevation on line y y, Fig. l. Fig. 3 is a top View. Fig. 4 is a horizontal section on line 2 2, Fig. 2. Fig. 5 is a horizontal section on line 23 3, Fig. 2. Fig. G is a horizontal section on line et 4, Fig. 2; and Fig. 7 is ahorizontal section on line 5 5, Fig. 2. Fig. S is a section of the wastevalve. 1

The stand-pipe a has an inlet-opening b for the water at one side near the lower end, and a valve-face c surrounds said opening on the outside of the tube. This valve-face is inclosed in valve-chest d, bolted on, as at e, said chest being faced on the inside for a gate-valve 3o f and having the pipe-connecting nozzle g on the back for connection with the water-main. On the back of the valve is a tubular packingfollower h, closely fitted in the bore of the nozzle and having springs t' to keep it in contact with the valve to prevent leaking into the box. The valve is connected to the rod j, which enters the valve-box through the stuffing-box k, and is secured by a pin Z, the joint being made a little slack to favor 'close contact of the valve with the face c.

The stuffing-box for the valve-rod is formed on the end cover m of the valve-chest, together with a protective guard-tube 1t for the valverod, extending to the top of the stand-pipe along and in contact with the stand-pipe and having flanges o atintervals along it for bolting on to corresponding flanges p of the standpipe, said protective tube having a slot for the most part of its length on the side next to the stand-pipe and being faced to fit a corresponding face of the stand-pipe, as shown at q, sufficiently to exclude surface water and protect against freezing. In the top of this rod-protecting tube is a nut q', screwing on the rod, to open and close the valve, said nut being confined under cap s by the collar t and having a spur u extending up through the cap for the application of a wrench for turning the nut. The slot in the protective tube facilitates inserting the valve-rod and adjusting the stuffing-box before 'said tube is attac-hed to the stand-pipe.

The stand-pipe a is closed at the top by a removable cover n, which may be taken off to open the pipe for any purpose, and a hole w is made through the cover for inserting a rod which may sometimes be required to stir up any collections of matter that may settle in the bottom. The hole will be closed by any suitable plug. The discharge-nozzles are formed onv the stand-pipe near the top.

Over the waste-valve d', employed for the discharge of the water remaining in the standpipe a after the valve f is closed, I provide a protective case b', inclosing it in a chamber of larger. dimensions than the case of said valve to prevent it from being clogged with soil, which would otherwise pack closely around it, said case being perforated, as at c', in the lower portion for the escape of the water. d is a stop for the valve.

It will be seen that the construction of my improved hydrant is very simple, that it is not liable to get out of order, and that it is simple and reliable in opera-tion.

The construction and operation ofthe wastevalve are sameas in common use and form no part of my claim, but a section of such a valve is shown in Fig. 8 for illustration of the same. The ball e is pressed against its seat and prevents waste of water when valve fis open. The spring f unseai's the ball when valve fis closed and opens'the discharge-passage g for the water remaining in the stand-pipe.

I am aware that a protective sheathing of sheet metal has been applied over the lower portion of the rod of a waste-valve and over said valve, fitted in an independent part attached to the stand-pipe, as in Patent No. 485,409, and I make no claim to such device, my invention being an improved construction of the main-valve case exterior to the standpipe, with an integral protective tube for the main-valve rod extending to the top of the IOO stand-pipe and Containing the nut for operating the valve.

I claim- `l. In a hydrant having a gate-Valve in a valVe-inelosing ease exterior t0 the standpipe and detaehably attached thereto, said case formed with a protective cover for the valverod consisting of an integral vertical extension of the Valve-rod stufng'box alongin eontact with and bolted to the side of the standpipe, said Cover ehambered in the side bearing against the stand-pipe for the rod and the stuffing-box gland, and being extended to the top of the stand-pipe and having the rod-aetu ating nut itted in the top substantially as described.

2. The combination in a hydrant, of the lXf'alVe-ease substantially as described.

Signed at New York city, in the county and State of New York, this 17th day ,of September. A. D. 1895. Y I

VNEIL MALMQVIST.
