VALVE.

SPECIFICATION forming part of Letters Patent No. 592,986, dated November 2, 1897. Application filed April 27, 1897. fierial No. 634,129. (No model.)

To ctZZ whom it may concern:

Be it known that I, GEORGE W. Fon'rnnn, a citizen of the United States, residing at Moweaqua, in the county of Shelby and State of Illinois, have inventeda new and useful Valve, of which the following is a specification.

My invention relates to valves, and particularly to check-valves, and has for its objectto to provide a valve of which the parts may be readily disassembled and wherein lateral access is given to the valve-seat, whereby the members thereof may be reached for cleanin g without disconnecting the casing from the pipe or conveyer sections of which it forms a union.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a longitudinal sectional view of a valve constructed in accordance with my invention. Fig. 2 is atrans- 2 5 verse sectional. view. Fig. 3 is a detail view in perspective of the guide. Fig. at is a detail view of thevalve-seat detached.

Similar numerals of reference indicate corresponding partsin all the figures of the d raw- 0 ings.

1 designates a casing provided with terminal male and female threads for attachment to contiguous portions of pipe or conveyer sections and also provided with a lateral 5 opening 2, which is closed by a removable cap-nut 3. In one end of the casing is formed a shouldered valve-seat rest at, in which is re movably fitted a valve-seat 5, having a circumferential enlargement or shoulder 6 to engage the shoulder of the rest and fitting snugly in the cylindrical bore of the casing beyond the shoulder of the rest to avoid the necessity of employing fastening devices. The

valve-disk 7 is provided with a winged guide 8 to fit in the bore of the valve-seat and also with an axial cross-sectionally-round extension 9 to fit in a guide-opening 10 in a removable guide-arm 11, said guide-arm being provided with a segmentally-rounded blade 12,

which fits peripherally in a guide-groove 13, formed transversely in the casing opposite to the lateral opening 2 and provided at the opposite end with a winged arm lat to fit in a cross-sectionally-round socket 15 in the capnut.

It will be seen that the socket of the capnut supports one end of the guide-arm, while the guide-groove in the wall of the casing supports the other end of said arm, whereby the valve-disk is free to move sufficiently to unseat, While at the same time it is guided both above and below its plane, respectively, by the winged guide and the extension. Furthermore, it is obvious that byremoving the cap-nut the guide-arm may be displaced, thus releasing the valve-disk and allowing it, with the valveseat, to be displaced for cleaning, regrinding, or repairing in other respects.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my intention, what I claim is-- 1. The combination of a valve-casing having a lateral outlet provided with a removable closure, a valve-disk seated in the casing and provided with an axial extension, a guidearm having a guide-opening to receive said extension and with a flat blade seated in a transverse groove in the casing, the other end of said guide-arm being fitted in and engaged by a socket in said closure, substantially as specified.

2. The combination of a valve-casing havin g a lateral opening, and provided in its wall opposite said opening with a transverse groove 13, a removable closure fitted in said opening and provided with a round socket 15, a valvedisk seated within the casing at one side of said lateral opening, and having a stem 9 extending axially of the casing to a point midway of the lateral opening, and a guide-arm having a flat blade fitted terminally in the groove 13, arranged transversely in the easing, and provided at its opposite end with a radially-winged head 14: fitting snugly in the socket of the closure, said guide arm being my own I have hereto affixed my signature in provided with a central guide-opening to rethe presence of two Witnesses. ceive the alvestem, and both guide-arm and the valve being removable through said lat- GEORGE FORTI 5 eral opening when the closure is displaced, WVitnesses:

substantially as specified. J. O. ARMSTRONG;

In testimony that; I claim the foregoing as R. E. WETZEL.
