CHECK-VALVE. 7

Specification of Letters Patent. Patented Dec. 23, 1919.

Application filed August 2, 1917, Serial No. 184,083. I Renewed November 5, 1919. Serial No. 335,907.

To ZZZ whom it may concern:

Be it known that 1, FRANK 1V. LEIDEOKER, a citizen of the United States, residing at Okmulgee, in the county of Okmulgee and State of Oklahoma, have invented a new and useful Check-Valve, of which the following is a specification.

The subject of this invention is a check valve wherein a valve and its seat are adjust-ably held within the valve casing.

The present invention constitutes an improvement in the check valve for which Letters Patent No. 996099 were issued June 27, 1911.

The main object of the invention is to provide a check valve in which the casing may be turned to various positions with respect to the valve.

Another object is to provide means for locking the valve and casing together.

Still another object is to provide a simple and efficient check valve.

With the foregoing and other objects view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made ithin the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawing, wherein:

Figure 1 is a central longitudinal section of the device, the valve and its seat shown in elevation.

Fig. 2 is a rear elevation with the clampingplate removed.

Referring to the drawing by numerals of reference:

The valve is constructed of a main casing 1, preferably cylindrical, with an interiorly threaded discharge orifice 2 at one end and an outwardly extending annular flange 3 at the opposite end. The flanged end of the main casing is countersunk, as shown at 4 and at one point contiguous the periphery of the countersunk portion, a pin 5 is secured in the casing in any suitable manner.

The flange 3 is provided with spaced apertures for the reception of bolts 6, by means of which a centrally apertured and threaded clamping plate 7 is bound to the main casmg. The clamping plate 7 is provided with the countersunk portion 8 as shown.

A laterally extending connecting nipple 9 is formed on the casing 1 so as to permit an angularly disposed branch line to be connected to the main line or to permit a line to'be turned at an angle.

Within the casing 1, and having a close sliding fit therewith, is a cylindrical member 10 formed with a scarfed end 11 which forms an inclined valve seat. A clap valve 12 hung from a cross pin 13 which turns in suitable apertures in the member 10 is adapted to normally rest upon the inclined seat 11 to which it is directed by gravity.

The cylindrical member 10 is provided at a median point, with an outwardly extending annular flange 14 which is adapted to be seated in the countersunk portion 4 of the casing, and which is provided about its periphery with spaced grooves or notches 15 which are arranged to selectively receive the pin 5.

The rear end 16 of the cylindrical member 10 seats in the countersunk portion 8 of the clamping plate. A packing ring 17 may be interposed between the clamping plate 7 and the flange 14 if desired.

In practice the device operates as follows: The check valve, of course, performs its functions in the usual way. Should it be desired. however, to direct liquid upwardly or to the right, or to the left, these positions maybe provided for with this valve by removing the clamping plate, withdrawing the cylindrical members 10 until the pin 5 is disengaged from the notch 15, turning the casing until the nipple 9 is extended in the direction desired, and then forcing the member 10 into place with the pin 5 again seated in a notch 15 and locking the parts together.

As will be readily understood, by this arrangement the valve is always maintained in a proper upright position so as to be closed by ravity.

While but four notches 15 have been shown herein, it is understood that as many as desired may be supplied.

Having thus described the invention, what is claimed as new, and sought by Letters Patent, is:

In a check valve, a casing having a laterally extending connecting nipple to receive a branch pipe, said laterally extending nipple being recessed, a pin secured to the casing and extending "from the recessed portion, a cylindrical valve member adjustably supported in the casing, said valve member having a notched flange lying Within the recessed portion of the nipple, said notches adapted to selectively engagethe pin for 10 holding the valve member in various positions of adjustment, and means for holding the valve member in place in the casing.

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

FRANK WALLACE LEIDECKER.
