JOHN MARCHANT, OF BEDDING, CALIFORNIA.
CH ECK-VALVE.
To all whom it may concern:
Be it known that 1, JOHN MARGHANT, a
subject of the King of England, residing at.
or compounds in gaseous or liquefied form are caused to pass under high pressure.
The device is more particularly designed for use in connection with compressed-air apparatus, but is not necessarily limited thereto, and may be employed in connection with any form of apparatus for which it is adapted.
With these and other objects in view, which will appear as the nature of the inven tion is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.
In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and genoral assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages.
In the drawings, Figure 1 is a sectional elevation of a conduit and check-valve with the improvements embodied therein. Fig. 2 is an enlarged sectional view of the reliefvalve detached.
The improved device comprises a casing 10, having an intake-pipe 11 leading therein at one side and an outflow-pipe 12 leading therefrom at the other side, the three parts forming a conduit for the material, as will be obvious.
The casing portion of the conduit is pro vided with a bushing 13,forming a seat for a check-valve 14 of any approved form, the check-valve having a plunger 15, preferably in cylindrical form, extending from the outflow side.
Supported, as by a spiderrframe 16, within the casing portion 10, above the outflow side of the check-valve, is a compres- Specification of Letters Patent.

sion-chamber 17, having at one side a cylin drical extension 18, in which the plunger 15 operates, as shown.
The walls ofthe compression-chamber are provided with a lateral extension, and formed in said extension and communicating with the compression-chamber is an aperture 19, in which a relief-valve 20 is seated, the latter opening outwardly and limited in its movement by a stop 21.
The relief-valve is provided with a trans verse aperture 22 and an intersecting lone gitudinal aperture 23, as shown in Fig. 2, to
provide means for the escape of the air or liquid when the valve is open.
The plunger 15 is preferablyhollow to lessen the weight, and. the chamber 17 18 is connected to the frame 16 byv a transverse pin 24 to facilitate its insertion and removal, and one side of the casing 10 is provided with a detachable closure 25, through which the valves and chamber may be inserted and removed.
The Whole device is simple in construction, compact, strong, and durable and may be manufactured at a very slight increase of expcnse over an ordinary check-valve of this class, while possessing very material advanta esover the same.
' in operating the device when the checkvalve lifts the plunger 15 compresses the air in the chamber 17 and a portion is forced outward through the relief-valve 20 and causes a partial vacuum in the compressionchamber, and when the pressure is reduced by the return stroke of the compressing mechanism and the check-valve thereby reseated the partial vacuum retards the movement and counteracts the tendency of the check-valve to instantly reseat. This produces a silent valve and likewise materially reduces the wear on the seat, while at the same time not deleteriously affecting the valve action.
The partial vacuum above referred to is maintained in the compression chamber after the valve is reseated and serves at the neXt stroke to lessen the force necessary to operate the valve, thereby making the latter more sensitive and easier to operate.
Having thus described the invention, what is claimed is 1. A conduit provided with a compre ssionchamber, a relief-valve provided with a longitudinal opening communicating with the compression chamber, and a check-valve serving to close said conduit and provided with a plunger operating in said compressionchamber.
2. A conduit provided with a compressionchamber the side walls of which are extended to form a depending cylinder and provided with a transverse opening,a relief-valve seated in said opening, and a check-valve serving to close said conduit and having a plunger operating in the depending cylinder of the com pression-chamber.
3. A conduit rovided with a compressionchamber the si e walls of which are formed with a lateral extension provided with a longitudinal opening communicating with said chamber, a relief-valve seated in said opening, and a check-valve servin to close said conduit and provided with a p lunger operating in the compression-chamber.
.4. A conduit provided with a compressionchamber the side walls of which are pierced by a transverse opening, a relief-valve seated in the opening and formed with intersecting longitudinal and transverse recesses, and a cheek-valve operatin to close the conduit and provided with a pdunger operating in the compression-chamber.
5. A conduit provided w th a compressionchamber the side walls of which are pierced by a transverse opening and provided with a depending cylindrical extension, a hollow relief-valve seated in said opening, a stop ex tending across the opening to limit the longitudinal movement of the valve and a checkvalve operating to close the conduit and provided with a plunger operating in the compression-chamben 6. A conduit including a casing provided with a detachable closure, a compressionchamber arranged within the casing and having its side walls pierced by a transverse opening, a hollow relief-valve seated in said opening, and a check-valve serving to close the casing and provided with a plunger operating in the compression-chamben 7. A conduit including a casing provided with a detachable closure and a reinforcingspider having a central recess formed therein. a compression-chamber arranged within the casing and provided with a reduced extension engaging the recess in the spider and having its side Walls pierced by a transverse opening, a hollow relief-valve seated in said opening, a check-valve serving to close the casing and provided with a plunger operating in the cornpression-chamber, and a transverse pin engaging the extension of the compression-chamber and the wall of the recess.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
