SAFETY VALVE.

UNITED STATES PATENT orrron.
.ALBERT SECHRIST, OF DENVER, COLORADO, ASSIGNOR TO THE ALBERT SECHRIST MANUFACTURING COMPANY, OF DENVER, COLORADO, A CORPORATION OFCOLO- MDO.
SAFETY-VALVE.
Application led December 6, 1918. Serial No. 265,510.
To all whom t may concern Be it known that I, ALBERT SEcHRrsT, a citizen of the UnitedV States, residing at No. 2233 Albion street, in the city and county of Denver and State of Colorado, have invented certainnew and useful Improvements in Safety-Valves; and I do declare the following to be a full, clear, and exact description 'of the invention, such as will enable others v'skilled in the art to which it alppertai'ns to make and use the same, reference Ibeing had to the accompanyingdrawings, and to the characters of reference marked thereon, which form a part of this specification.
This invention relates to safety valves for pressure cookers. The obj ect is to construct a valve which is comparatively simple and may be readily taken apart for cleaning, thus making ita sanitary valve.
Briey, the invention comprises a member havi a passage therethrough and a seat for a bal valve. Detachably connected with this seat memberis acasing carrying a removable spring pressed plunger, the inner end of which bears against the ball and controls the pressure vin the cooking vessel. The spring is so housed that steam or water escaping through the valve will not come into contact with it, the upperpart of the casing being arranged to provide a seat for the ball valve when in its-upper position, thus cutting of passage of steam or water above the valve and into the spring housing. Steam escapes through apertures in the casing Iat the side of said housing.
In the drawings: Figure l is a vertical section taken on line 1 1 of Fig. 3,l the ball valve being in lowermost position.
Fig. 2 1s a vertical section showing the .ball
valve in elevated` position, arrows indicating the passage of the steam.
Fig. 3 is an elevation indicated by line a-s of rig. 1.
Fi 4 is a horlzontalsection von line 4 4 of Fig. 1; and
Figs. 5 and 6 are horizontalsections on lines 5 5 and 6 6 of Fig-2.
A fragment of a cooker top 4is represented by C, and into this the valve body 10 is threadedr Ehebody is shouldered externally at 11 andv has a passage 12, the upper part of which is expanded and constitutes a seat 13 for the valve ball 14. A casing 15 normally incluses the ball 14 and thebody 15,
resting upon the shoulder 11 and being) reayonet slots 16 on the casing and pins 17 promay movably held in position by means of jecting from the body.
The easing is offset at 18 and 'provided with-a row of apertures 19 for the escape of steam. Above the casing 15 the extension 20, having a cap 21', houses a plunger 25 which is provided with a spring seat or flange 26 between which and the cap 21 an ex'-` pansion spring 27 is placed. The upper endof the plunger extends through the cap 21, while the lower end 125 thereof below flange 26 extends through a plate or washer 28 and rests upon the top of the ball 14. It has been found that for best results the lower extremity of the plunger should be cut square across as Shown at 30. The plate or washer 28 is swaged into position and proper positioning of it may be employed for setting the tension of the spring 27. The tension of the spring may be regulated by means of the cap 21 Patented Janes, 1919.
which is threaded onto the housing 20; this provides a simple means for setting the valve to operate at any desired pressure. 4
The lower portion 125 of plunger 25 is made to fit plate or washer 28 rather snugly to protect the spring in its housing from escaping steam, and to more definitely aceomplish this object the internal annular shoulder 35 is proportioned to provide a seat for the ball 14 when the latter is in elevated position as shown in Fig.v 2. Under these conditions,l when the valve pops and steam (and possibly' water also) is expelled, the seating of the ball on the shoulder 35 and the tting of the plunger in plate 28, eilectually out oil the housing 2O from the eseap- I sembled.
, I claim: 1. A sanitary valve comprlmng a body member having a seat, a valve member 1n said seat, a caslng to retain said' member,
and a second seat above the seat in the body thenbe thoroughly cleaned and reasiool lspring pressed plunger above said valve member and engaging the top thereof.
2. A Sanitary safety valve comprising a body member having a seat, a valve member in said seat, a removable casing to retain said valve member and having a second Seat above the first seat for said valve, and spring-pressed means in said easing engaging said valve member.
3. A sanitary valve comprising a body member having a seat, a valve member in into engagement With the valve member.
4. A sanitary valve comprising a body member having a seat, a valve member in said seat, a casing to retain said member, a
housing on said casing above said valve member, an apertured partition adjacent the bottom of said housing, a plunger extending from said housing through said member, slidably fitting in the same and engaging the top of the valve member, and a spring in the.A housing forcingsaid plunger into engagement With the valve member.
5. A sanitary valve comprising a body member havin said seat, a casing to retain said member, a housing on said casing above said valve member, an apertured partition adjacent the bottom of said housing, a plunger extending from said housing through said member, slidably fitting in the same and engaging the top of the valve member, and a second seat adjacent the bottom of said housing, below said partition and above said valve member, in which the valve member is adapted to engage and close When said valve member is -in its uppermost position.
In testimony whereof I affix my signature.`
