CHECK OR, CLAQK VALVE.

SPECIFICATION forming part of Letters Patent'No. 705,255, dated July '22, 1902.

Application filed January 4:, 1902; Serial No. 88,461. (No model.) I I I T0 at whom it may concern: 1

Be it known that I, FRANK W. LEIDECKER; a citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented a new and useful Check or Clack Valve, of which the following is a specification.

This invention relates to back pressure valves, commonly known as clack-valves.

The object of the invention is to provide a valve which is freely movable in its bearings and which has a peculiarly-constructed hinge which is especially adapted to this formof valve. 7

Figure 1 of the. accompanying drawings represents a plan view of a'pipe-seotion with this improved clack-valve applied thereto. Fig. 2 represents a longitudinal vertical section thereof, the open position of the valve being shown in dotted lines. Fig. 3 represents a transverse section taken on line 3 3 perspective view of the valve detached.

The same reference-numerals indicate corresponding parts in all the figures.

In the form shown in the drawings the valve is shown applied to an exteriorlyscrewthreaded pipe-section 10, which is'adapted to be screwed into any form of pipe either directly or through the medium of a pipe-coupling. It is preferred to make thesevalves in connection with such a section, which may be made and sold as a separate article of manufacture and applied to any desired pipe with which it is desired to use it, either in a gas=pipe or in a water system.

The pipe-section 10is preferably made with a reduced eXteriorly-screw-threaded portion 11, and near the center an enlarged collar 12 is formed, which provides an abutting shoulder 13 for the inner end of a pipe to be connected with said reduced portion. The collar 12 is preferably provided with angular faces, adapted to be engaged by a suitable wrench for screwing the section 10 into a pipe or pipe-coupling. The front part of the sec tion 10 on the inner side of the collar 12 is preferably made slightly larger in diameter than the portion 11 and is also exteriorly screw-threaded to receive'anotherpipe to be attached thereto? This front portion 14 is cut obliquely to its axis, as shown in Fig. 2,

to be readily inserted in a pipe.

toform an inclined valve-seat 15. The part above said valve-seat is closed in to form a ders are rounded to-conform to the shape of the contour of the section 10 and to adapt it (Not shown.) A valve 20, preferably leaf-shaped and having a beveled or rounded upper face, is provided at the upper edge thereof with an upwardly and outwardly extending valve-stem 21, preferably made angular in cross-section and adapted to fit in the opening 18 between thelugs 16 and 17. The upperends or edges 22 and 23 of the stem 21 are adapted to fit closely against the front lower edges of the lugs 16 and 17. The outer end of the stem 21 is connected to or made integral with a rod 24:, extending at rightangles to said stem and provided at its opposite end with beveled faces adapted to conform when in position to the contour of thepipe-section 10. The ends of said rod 24, disposedon opposite sides of the stem 21, will be designated as 25 and 26.

In assembling the parts the rod 24 of the valve is inserted in the channel 19, with the end 25 thereof'extending through the closed portion at the back of the lug 16 and the end 26 thereof resting in theopen portion of this channel 19. The valve is then swung downward, and the stem 21 thereof fits in the channel or opening 18 between the lugs 16 and 17 and permits the clapper to seat itself on the valve-seat 15. The valve is thus locked in position against sidewise movement, while permitting it to swing freely up and down or back and forth, according to the location of the pipe. Then the section 10 is screwed into a pipe, the inner face of the pipe locks the hinge against accidental upward or outward movement while permitting it toswing freely in its bearings formed by the channel 19and the lugs 16 and 17.

It is obvious that this improved valve may be placed either vertically or horizontally, or it can be in line with the inlet and outlet or in any other desired position without affecting the operativeness of the valve.

This peculiar construction of the valve and its hinge connection avoids the necessity of using rivets or any otherfastening means, which are liable to become rusty, wear out, or ailect the operativeness of the valve in any such manner.

The Valve herein shown and described embodies a removable self-adjusting clapper, which is a self-seater and which is drainable without interference.

I claim as my invention 1. The combination with a pipe-section having an obliquely-cut-off discharge end and a closed-in portion or bridge above said dis charge, of lugs rising from said bridge and a valve or closure for the oblique discharge end having a stem engaging between said lugs and having bearings therein, substantially as set forth.

.3. A pipe-section having its discharge end cut obliquely to its axis and having a closedin portion or bridge above such oblique (lischarge, in combination with a valve seated upon the latter and having a stem seated between lugs upon the bridge-piece and having a transverse head or cross-piece engaging bearings in said lugs, the latter being beveled upon the front sides, substantially as set forth.

3. A pipe-section having an oblique discharge end and a closed-in portion forming a bridge above the same, lugs rising from said bridge and having beveled front sides and rounded edges corresponding with the contour of the pipe, one of said lugs being transversely perforated, and a transverse slot in the opposing lug, and a valve seated upon the oblique discharge end of the pipe and having a stem, engaging between the lugs rising from the bridge and provided with a cross-piece engaging the perforation and slotin said lugs, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

FRANK \V. LEIDECKER.
