VALVE.

SPECFICATION forming part of Letters Patent No. 397,134, dated ebruary 5, 1889.

I Application filed August 3l, 1888.

` opening', ll, which is adapted to align with To all whom it 71mg/ con/cern:

Be it known that I, GEORGE ADELBERT MATTESON, a citizen of the United States, residing' at Cridersville, in the county of Auglaize and State of Ohio, have invented new and useful Improvement-s in Valves, of which the following is a specification.

rlhe object of my invention is to provide a combined stop-cock, clieclovalve, and connec-` tion or union for steam, fluid, or gas lines, whereby the inconvenience of separately connecting the stop-cock and the cheek-valve to the line may be avoided.

A further object of the invention is to provide means whereby the check-valve may be removed at any time to repair or clean.

lith these objects in view the invention consists in a cert-ain novel construction and combination of devices, fully described hereinafter, in connection with the accompanying drawings, and specifically pointed out in the appended claims.

In the drawings, Figure l is a side view of a stop embodying my improvements. Fig. 2 is a central longitudinal sectional view of the same. Fig. il is a central transverse sectional view with the valve open. Fig. l is a similar view with the valve closed. Fig. 5 is a de` tail perspective view of the check-valve with its removable seat. Fig. 6 is an end view, partly in section, of the casing.

Referring by letter to the drawings, A designates the casing of the stop-cock having the transverse bore a., and the upper end of the casing is provided with the horizontal flange B, to which is adapted to be bolted a pla-te, C, having a rigid nut, c. This nut is screwed on the lower end of a section of the line-pipe D. It will be seen that this plate and nut form the connection or union between the line-pipe and the stop cock. The under side of the plate O is provided with a depending rib, E, which iits in an annular groove, e, in the upkper side of the flange B, and bears on a packing-ring, F, which is located in the groove.

The core G of the stop-cock is conical in form, fits in the bore a in the usual way, and is held in place by a suitable nut, g, which is screwed on the smaller end of the core. The core is provided with a transverse elongated Serial No.284,272. (No model.)

I the vertical opening in the casing to allow the passage of the steam, fluid, or gas.

I represents a recess, which is formed in the side of the core G, in which is arranged the valve-seat K, having an opening, k, therein, which registers with the opening H in the core, and on the outer side of this seat is hinged the check-valveL, which is thus received completely within the recess in the core. When the stop-cock is open, this eheck valve hangs loosely, thereby leaving' its seat l and allowingI the passage 0f the steam, ilnid,

or gas; but the lower edge of the said valve projects slightly into the vertical opening of the casing, whereby, if the pressure is too Violent, the valve will be partially or entirely closed. Then the stop cock is closed, the check-valve is turned around on the upper side of the core, and its lower edge, or a rib, l, on its out-er side, bears against the side of the bore a and holds the check-valve tightly in place. The object of this rib is to prevent the entire side or lower edge of the checkvalve from bearingv against the side of the bore, since in case the latter should become corroded or rusted, the rib would not be as liable to cling to the side of the bore and prevent the operation of the stop-cock as if a larger surface were in contact therewith.

The manner of hing-ing the check-valve is as follows: lt is provided at its ends with the trunnions L L', which are mounted in bearings R R in the sides of the recess I. One of these bearings is open at one side, to enable the valve to be removed from the easing. lVhen the stop-cock is closed, the transverse opening H therein assumes an approximately horizontal position,(out of alignment with the opening in the casing) with its open end adjacent to the side of the casing; and therefore to allow a perfect draining of the stop-cock and check-valve, when in this position, l provide a vent, M, in the side of the casing in such position as to allow the escape of any accumulation.

It will be readily seen that having combined the check-valve with the stop-cock it is only necessary to make one connection, instead of more, and therefore time is savedv in IOO putting,l the device in place, in liddition to the time, material, and expense which are saved ill the oollstruetion thereof.
