FIRE-HYDRANT.

SPECIFICATION forming part of Letters Patent No. 550,595, dated December 3, 1895.

Application iiled March 1, 1895. Serial No. 540,165. (No model.)

To all whom t may concern:

Be it known that LWILLIAM WV. COREY,J r. a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Fire-Hydrants, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, wherein- Figure l is a sectional view of my improved hydrant, showing the valve unseated. Fig. 2 is a similar view showing the valve seated. Fig. 3 is a top plan view taken through the joint of the stand-pipes. Fig. t is a sectional view taken on line 4 4:, Fig. 2. Fig. 5 is a sectional View taken on line 5 5, Fig. 2. Fig. 6 is a front elevational view of the drip-valve. Fig. 7 is a back elevational view of the valve and its operating-links, and Fig. 8 is a modiication of the link connection to the valve.

This invention relates to a new and useful improvement in lire-hydrants; and it consists in the construction, arrangement, and combination of the several parts comprising my invention, all as will hereinafter be described, and more fully pointed out in the claims.

The objects of the invention are to so combine and arrange the valve-operating mechanism that the valve when seated is closed against the pressure of the water, and when the valve is unseated it is withdrawn from the path of the active or live water and submerged in a bank of dead water.

Another object is to so construct and arrange the parts that the main valve and dripvalve can be withdrawn from the stand-pipe without disturbing the stand-pipe and without the necessity of removing the same from its buried position.

Another obj ect is to arrange the links which operate the main valve in such manner that the links guide the valve in its movement in the absence of any guideway.

In the drawings, Aindicates the stand-pipe, which may be coniliosed of two or more sections, the upper part of which is not shown, but which is of any ordinary or approved construction-that is, is provided with a cap and squared shank on the valve-operatin g rod, whereby the latter may be turned to operate the valve.

B indicates the valve-operating rod, which inginto the interior of the stand-pipe.

is formed with or has attached to its lower end a threaded section O, cut with threads of the right. and left hand order.

- O' indicates a threaded section at the end of section C, which threaded section O is preferably cut or formed with threads of less pitch than the section C.

D indicates kthreaded blocks, which are mounted upon the rod C, which in rotating adjusts the blocks toward and from each other. Projecting from the sides of these blocks in different horizontal planes are pivot-studs d, upon which are mounted the valve-operating links. These studs d proj ect from opposite sides of the block, one stud being located near the upper edge of one side and the other being located near the lower edge of the other side, as shown at the top of Fig. 7. E indicates the main valve, which is preferably formed with a conical face, which assists in centering it in its seat F, located at the entry ofthe main to the stand-pipe. This valve is formed with or provided at its back with suitable means, preferably in the form of projecting ribs E', to which are pivotally connected the links G, whose other ends are pivoted on the studs d of the blocks D. Links G are pivoted to the ribs E in such manner that their pivot-points are on different horizontal planes, corresponding to the difference of the plane of their connection to the block D. In this manner the links are the same length; but the different points of connection between the links, the blocks D, and the valve causes the valve to have a straight movement toward or from its seat, taking away the tendency of the valve to wabble.

The connection of the links to the valve is shown in simplest form in Fig. 7, wherein the diametrically-opposite links are connected to a central pivot-pin, while the remaining links are mounted upon side pins diagonally opposite each other. In Fig. 8 I have illustrated an obvious modiiication, in which the central link is disposed of and in its place are two links arranged on different planes. The result, however, in the operation of the valve is the same in both constructions. Y

' Arran ged in the lower end of the stand-pipe is a sleeve H, open at its top and bottom and formed with an opening or openings h, lead- Op- IOO erating in this sleeve is a valve I, preferably of that form known as a cup-valve-that is, the upper face of the valve is recessed, leaving an edge iiange, which under pressure of the head of water exerts a tendency to spread and make a tight joint.

J indicates the stem of valve I, which stem extends upwardly and is formed with an interior screw thread, which receives the threaded section C. Above the interior threaded portion of the valve-stem I prefer to form an extension J from the sides of whichproject wings J which are seated in a guideway formed in the stand-pipe to guide the drip-valve in its movement. This extension J besides performing' the function of guiding the valve, also acts as a spacer to insure the proper position of the valve before the parts are assembled, thus obviating the necessity of adjustment after the stand-pipe has been buried, which could not be easily done. This is accomplished in the following manner: Then the blocks D are placed in p osition and the valve, with its links G, mounted on the blocks, is ready for insertion in the stan d-pipe,the parts are in the position shown in Fig. l. Valve I, with stem J, is screwed on section C until the extension J abuts against the lower block D. The parts are now inserted, and this predetermined adjustment obviates a second adjustment when the valves and their operating mechanism are in operative position.

In order to guide the parts mounted on rod B or its section C without subjecting' said rod to a twisting strain, I prefer to form oppositely-extending lips A in the lower section of the stand-pipe, which lips form a way, in which is located the section C. The blocks D are formed with squared faces at their backs, which faces, however, do not contact with the rear side of the way. The ends of links G, which are connected with blocks D, are formed or provided with projections in the form of bosses, which extend into the lateral-pockets of the way. These bosses are of such dimensions that the ends of the links contact with the rear face of the way, while the front faces of the bosses rest upon the lips A. The curved movement of the links in their operation partially rotates the bosses, and to accommodate this they are preferably formed circular.

In operation when the lower section of the stand-pipe is connected to the main and buried the main valve and drip-valve, adjusted as before stated, are inserted in position, when the hydrant is ready for operation. By rotating the rod B the right and left screwthreaded section C adjusts the blocks D longitudinally thereon, causing the links to force the valve E to its seat. If the hydrant had been running before and the water was left in the stand-pipe, valve I would be raised above the opening h by the threaded section C and the water would leak through to prevent freezing and accumulation. Vhen the valve Eis drawn back from its seat by rotating the rod B in the direction opposite to that before described, the valve I is forced below the opening h, thereby closing communication between the stand-pipe and the eX- terior and cutting off the drips. When the valve E is fully withdrawn, as shown in Fig. 1, it is removed bodily from the path of the live water and occupies a position substantially in a bank of dead or inactive fiuid. By the long sweep from the valve-opening to the joint between the two sections of standpipe the live incoming water is permitted to follow closely this line, which carries it above the valve E. In this manner it will be seenthat there are no obstructions in the path of the incoming` fluid, and the valve E occupies i a position where it is removed from the line of pressure of the incoming water, which thereby relieves it of any torsional or twisting strain.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a hydrant, the combination with a standpipe, of a valve operating` rod located therein, blocks arranged on said rod which are adapted to move toward and from each other, links which are pivoted on different horizontal planes on the blocks, and a valve to which the opposite ends of the links are pivoted on different horizontal planes; substantially as described.
