n.1. PuUNE-R, or BELL-Enorme,'PENNSYLVAN1A- To all whom it may concern Be it known that I, -D. I. Pnnlynaof Bellefontc, in the county of Centre, and State of Pennsylvania, have invented a new and valuable Improvement in Hydrants; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of. the same, reference being had to the annexed drawings, making a part of this specification, and to the' letters and figures of' reference marked thereon.

Figure l, of the drawings, is a representation of my.

invention, with the front portions of the casings removed.'

Figure 2 isa vertical cross-section of the same.

' My invention relates to hydrants, and consists, mainly, iu the construction and novel arrangement of devices, Awhereby 'a hydrant is rendered non-freezing, and the parts below ground arranged in a'case, so that they can be drawn up for repairs, without excavation.

' Theletter A of the drawings designates the outer ,casefor pit-lining, of wood.

This is a rectangular' box, open at the top, which is let down into the earth, until the edgesof its top are ush with the surface. It is partly open at the bot'- tom, for drainage.

The supply-pipe a, from the ground, passes up i through the shelf b, arranged across the bottom of the case A, 'and is secured into an openingin the cap c.

The cap chas a circular lip around the mouth of the opening, and a slanting shoulder, a.

When the hydrant. is pushed down into its place, the plate B, attached to the lower end of the pipe c', meets the upper slanting face of the cap` c, and receives into a circular depression, in its own lower slanting surface, the lip of the cap c, thus forming a secure joint.

A disk, ot' leather, may be used around the lip of the cap c, as packing, if desired.

Attached tothe bottom of' the hydrantcase D is the lower plate Z ofthe cut-oiT-a plane, circular disk,

withthree openings, c,- e', and c, one'of which, e, communicates with the pipe c'. e' and c", are for drainage.

z is a metal plate, having a circular opening,.some what smaller in diameter-'than the upper disk t ofthe cut-oli', so that it presses upon the upper surface of' its rim, when clamped -by the screws s s, or other devices, hereafter described.

The meeting-surfaces of the disks l and tare ground and'polished perfectly smooth, so that when they are pressed together, no water can ooze between them.

The upper plate tis kept in ppsition by twosmall projections attached to the lower' surface of the clalnping-plate z, and by the curved front wall of the shoulder or elbow r.

The water, entering-by the opening in the disk t, is conveyed through the elbow r, passes up through the pipe p, and out at the spout q.

The other two openings,

side vents e e.

lKeyed to the lower end of .the pipe p are the jaws a, which embrace the sides of the elbow 1.

The pipe p and jaws a thus act as a wrench, by which .the disk tis turned, to let the water on, or out it ofi'.

A small spring, m, coiled around the pipe p, n ear the top of the hydrant, is used to keep Athe jaws n down, and the disksl and t are somewhat closed by it.

The pressure of the spring m is regulated by the nut o', working against the plate a'.

K K are struts, the feet of which rest on the plate z, and, being pressed down by the spring Sfwedges c c, or both, operate principally in keeping the disks l and tclosely together. v.

M represents a metal plate, secured firmly to the hydrantcase,"byv attaching vcleats above and belowl it.

This plateis 'so situated, that when the hydrant is -let down into the outer case A, far enough to bring the plate B in position on the cap c, it will be flush with and cover the top of the case A, and maybe secured thereto with screws in such a manner as' to .cause a pressure on the joint at B, and thereby render itwater-tight.

When the hydrant is turned on, all the water in the pipe p and elbow/r escapes through one of the Therefore, there. can be no'freezing above the cut-oli'.

By the use of a coiled spring, attached under the shoulder of the spout-head N, and secured to the top plate of the hydrant, the water may be out ofi' auto# matically.

What I claim as my invention, and desire to secure by Letters Patent, is

/1. 'The combination and arrangement of a pit-lining, A, and a removable hydrant, constructed with metal shoulder M, and attached to the supply-pipe by the slanting j oint-plates B and e, as specified.

2. In combination with a pit-lining, A, the remov-.

able hydrant, herein described, having slanting joint B, pipes p and c', cut-oii` disks l and t, shoulder 1', jaws a, springs S and an., struts vK, and plates M and z, constructed and arranged to operate as specified.

3. In combination with a pit-lining, A, the removable hydrant, herein described, having slanting joint Bypipes p and c', cut-oii disksl and t, shoulder r, jaws n, wedges c c, adjustable spring mf, struts K, and plates'M and c, as specified.

. 4. In combination with the cut-off plate t, with y elbow r, the plate l having three apertures, viz, an inlet, e,"and outlets e and e", constructed and arranged to operate as specified.

In testimony that I claim the above, I have hereunto subscribed my name, in the presence of two witnesses.
