JAMES CURRAN, 0F BALTIMORE, MARYLAND.
Laminaat Naseem, dated February s, i870.
l The Schedule referred to ln these Letten Patent nand making part ot the same.
To` all whom fitmay concern Be it known that I, JAMES CURRAN, of Baltimore, in the county of Baltimore, and in the State of Maryland, have invented certain newand useful Improvements in Fire-Plugs; and do hereby declare that the following Ais a full, clear, and exact description thereof', reference being. had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consistsin the construction and general arrangement of a fire-plug, as will be hereinafter fully set forth.
Inorder to enable others skilled iu the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part ofthis specification, in which- 1 .liigure l is a vertical section, showing a portion of :the inside casing or tube also in section;
-Figu're is a horizontal section;
Figure 3 is a plan view of the joint for the valvestem or rod; and
Figure 4 is a horizontal `s`ection of the valve-seat.
A represents the inner casing or vertical column, through which the water passes, and is allowed to be discharged through the apertures B B.
At the lower end of the column A is the valve-seat C, provided with grooves, as shown in fig. 4, for the insertion ofthe wings ofthe valve D.
The valve-rod E is, at its upper end, provided with a circular flange, which is inserted in the box F from the under side.
From' the upper side of the box F, a screw-rod, G, extends upward through ,the cap H of the ,column A.
',Ihe strew-rod G is, at its lower end, within the box F, provided with a circular flange, which confines this end wit-hin the box, so that the Ascrew-rod G may be turned in either direction, wit-hout causing the valvestem E to revolve, but allowing it to be raised or lowered, so asto open or close the valve.
Between the upper end ofthe vertical column or inner casing A and the cap H is clamped a cup, I, through which the screw-rod G passes. This cup I is very convenient to contain the oil 4for the screw, and at its bottom is a packing-box, J, which also serves as a Vguide for the valve-rod. The inner casing A is, at suitable points, provided with two horizontal circular collars a a, which have slots through their edges, as seen in iig. 2. These slots Iserve to hold the outer casing K, which is made in`two halves, and have flanges b' b at their inner edges. These flanges connect in the slots in the collars a a, and hold the two halves of the casing together.
Near the lower end of the casingK are'two vertical slots, in which are placed set-screws L L, the inner ends of which rest upon the lower collar a, so as to support the-casing K. By this means, tlielieight of the casing from the .pavement is readily regulated, and when the frost comes out of the ground, the casing is permitted .to rise up slightly, without disturbing the central Vcolumn A, and prevent breakage.
The upper portion of the fire-plug is enclosed by' 'and vertical slots, in which the set-screws L L areV adjusted, substantially as and for the purposes herein set forth.
2. The combination of the central .column A with collars a a, and the bisected casing K with flanges bxb and set-screwsL L, all substantallyas and for the purposes herein set forth.
3. The c'i'ip I and box J, secured, as described, be-
tween the column A and cap H, substantially as and I for the purposes herein set forth.
In testimony that I claim the foregoing,'41 have hereunto set my hand, this 5th day of February,
JAS. GURRAN. Witnesses:
J. W. STooPs, J. M. MASON.
