Specification forminglpart Letters Patent No.A 181,483, dated August 22, 1876; application lfiled j July 20,1876.

To all whom it may concern; y

of Cleveland, inthe county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrants and I do hereby 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 pertains to make and use it, reference being had to the-accompanying drawings, which form part of this specification.

My invention relates to anI improvement in hydrants; and consists in forming a longitudinal central shell around the valve-stem or key, so as to isolate it from contact with the water; also, in a novel arrangement of the valve-stem and valve-leathers, so that the leathers will close the waste-Weir when the hydrant is open, and open it when the hydrant is closed, as hereinafter set forth and claimed. f

In the drawings, Figure l is a longitudinal central section by a plane passed through the waste-Weir, exhibiting my invention. Fig. 2 is a plan view of the bushing above the valve, which supports the screw tapped collar, through which the key or valve-stem screws.

A is the service pipe or main, to which the `hydrant is attached, and which supplies water thereto. B is a case or shell, which is provided with the valve-seat C. D is the valve of any suitable construction-that in the drawing is represented as of leather or packing; but the particular construction of the valve forms no essential part of my invention. E'

is a bushing, located in the shell B, and is simply an open ring, which gives support to the screw-tapped ycollar F that holds the key or valve-stem G. This bushing Eis shown in plan view in Fig. 2. F is the collar that supports the. key or valve-stem G. It is screwtapped to correspond'with the screw cut upon the shaft Gr; and it may either have a frictionbearing within the bushing E, or, preferably, it is provided with a left-hand screw-cut surface, and the lbushing E is screw-tapped to correspondf rlhe upper end'of the collar F is tapped toreceive the lower screw-cut end of the inner shell or case H. The case H rises tothe top of the hydrant, as shown in Fig. l,

and prevents contact of'the water with the key Vor valve-stem G. I' is packing that is put Be it known that I, J EREMIAH E. SGANLAN,r

around the case H at the top to prevent Water from escaping around the case H. Kis the spout. J is a nut that runs down on the case H to hold the packing in place. F' is an an.- nular groove surrounding the collar F, and opening into this groove is a conduit, F, leading upward from the space beneath the collar F. From some point opposite the groove Fis an outlet, E', passing through the solid portion of the open bushing E, and out to the outside of the case. The groove F', and the conduits F2 and E', constitute the waste-Weir.

The operation is as follows: When the valve is raised by turning the key Gr, Water enters from the pipe A,'passes up through theopenings in the bushing E, thence up and out from the spout; at the same time, as the valve rises, it comes up against the lower' side c of the collar F, vand the valve-leathers close the waste-passage F. When it is desired to shut the hydrant thc valve-stem is turned hack. The valve is again seated, and as it descends the escape or waste passage FIl is opened, and I the water in the barrel or case is permitted to waste through the openings F, F', and E'.

For convenience in removing the parts for repairs and'readjusting them afterward, the bottom of the case H is screwed into thecol larvF with a right-hand screw, while the collar is, in turn, screwed into the bushingE with a left-hand screw, so that the case or barrel H can be used as a wrench for unscrewing the collar F from the bushing E.

It will be noticed that there is no packing of any kind around the key or valve-stem,

and that it is entirely free from the water, and

always free to act, and not liable to freeze up,

as is the lcase where the stern is permitted, when in use, to have contact with the water and it is these features-viz., the isolation'of the valvestem from the Water; the freedom ofthe stem from all packing; the arrange-A ment whereby the case H, and not the Valvestem, is packed; the relative construction of the. case H and collar F, whereby the former may act as a'wrench and the construction ofthe waste-Weir and its relation to the valveleathers-th at constitute the essen tial elements of my invention.

WhatI claim is l In" a hydrant, ,the combination, with the awe-stem and outer casing, of th'eInner casig H, rigidly secured at its lower end only, nd packed at its upper end, wherebyit may ave free longitudinal movement to expand lor ontract, substantially i as and fr the1A par@ -1 ose set forth. Y

2. 1n a hydrant, the combination, `with `the alve-st-em Gr and collar F, offthe"cuterreusing` l, inner casing H, and packing I, the packing erving to connect the casings, so that they lay have free `and l" independent `lon'giftnldina=l lovement, substantially as and for the ,pu-1 lose specified.

3. The case H, provided with right-hand crew at the bottom, in ccmhinationswith col u' F, `tappedinto'la support or bearingwith l,

4. The combination, with the collar F, of

i'tne` annular groove F and the conduits F" and E', the whole constituting a Waste-Weir.

l Thcehydangcomitig of a main barrel, case H, with packing I, collar F, bushing or. support i E, r waste-Weir, valve and valve- -steuunlilsnhstantially as and for the purposes ,set forth.
