ED STATES PAT FRANK WALLACE Lnibnoxnn, or MARIETTA, 0310.
To all whom it may concern: V
Be it known thatI, FRANK W. LEIDEGKER, 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-Valve, of which the following is a specification.
The invention which is the subject of the present application is an improvement over the valve shown in my Patent No. 705,255 granted July 22, 1902, the object being to dispense with all screw-threads, and also to provide a structure which makes the valve easily accessible and removable together with other improved structural details to be hereinafter described and claimed.
The invention is illustrated in the accompanying drawings in which,--
Figure 1 is a longitudinal sectional view of the complete structure. Fig. 2 is a perspective view of the valve carrier, seat and valve removed 'from its casing. Fig. 8 is an'elevation of a modification; and, Fig. 4 is a longitudinal sectional view thereof.
Referring more particularly to the drawings, 5 and 6 denote two members of a pipe receiving union connected by an ordinary coupling. ring 7.. The member 5 is a tee,
and the valve is located therein.
At 8 is'indicated a shortsection of pipe constituting what may be called the valve carrier and whose exterior diameter is smaller ,than the bore of the member 5 .so as to leave an annular space 15 between them. The carrier is formed at one end with an outstanding annular flange 9, and
has its opposite end cut obliquely to its axis to form an inclined valve seat 10, the carrier being open at both ends. The valve proper is indicated at 11, and as in my former patent it has a stem 21 with a T-head 12 at its outer end 'journaled in a channel 19 across Specification of Letters Patent. Patented June 27, 1911. Application filed May 25, 1909, Serial No. 498,235. Renewed May 17, 1911. -Seria1 No. 627,858.
The valve is located in liiie withthe side opening 13 of the T-member 5, in order that it may be accessible for inspection or repair.
Said opening, as seen in the drawings, is
as herein described it v is also possible to clean the same by simply removing the plug 14:, and it is not necessary to disconnect the two members of the, union when access to .the valve forv any pur ose is desired. No
.screw-threads'are required for holding the pipe section 8 in place, which greatly simplifies the structure, it being securely held between the two members 5 and 6.
The opening 13 is in the side of the member 5 in order that the water may run out of the same if the pipe line is to be drained.
Figs. 3 .and 4 show the invention applied to an ordinary flange tee, the flange 9 of the pipe 8 being held between the flanges of the, tee. V
Whatis claimed is: I The combination with a pipe receivin union, one member of which has a side opening at a distance from its ends, and a closure for the opening, of a check valve within said member comprising a relatively long the valve proper hinged to the inner end of .the carrier opposite said openin In testimony that I claim the lbregoing as my own, I have hereto ajfixedmy signature in the presence of two witnesses.
