Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
147 words
A system for controlling a combustible fluid, said system comprising: a valve body; a manual valve having a rotatable part with a flat surface; a safety valve in communication with said manual valve; a main burner; a pilot burner positioned adjacent said main burner; thermally responsive means including a thermocouple positioned adjacent said pilot burner; an electromagnet connected from said thermally responsive means to hold said safety valve open when said pilot burner is lit; a pin guided to slide axially and perpendicularly with respect to said flat surface of said rotatable part, said manual valve having a hole in said flat surface; and means to urge said pin to enter said hole when said safety valve is opened, said pin entering said hole and locking said part in a position fixed relative to said valve body when said manual valve is moved to its closed position.
Claim 2
Independent Claim
147 words
A system for controlling a combustible fluid, said system comprising: a valve body; a manual valve having a rotatable part with a flat surface; a safety valve in communication with said manual valve; a main burner; a pilot burner positioned adjacent said main burner; thermally responsive means including a thermocouple positioned adjacent said pilot burner; an electromagnet connected from said thermally responsive means to hold said safety valve open when said pilot burner is lit; a pin guided to slide axially and perpendicularly with respect to said flat surface of said rotatable part, said manual valve having a hole in said flat surface; and means to urge said pin to enter said hole when said safety valve is opened, said pin entering said hole and locking said part in a position fixed relative to said valve body when said manual valve is moved to its closed position.
Claim 3
Dependent Claim
75 words
The invention as defined in claim 1, wherein said manual valve part is rotatable about an axis, said manual valve part has a surface normal to said axis, said hole being a recess in said surface normal thereto, said pin being movably guided in said valve body in a direction parallel to said axis, said valve body having a hole therethrough with which said hole is alignable by rotation of said part about said axis.
Claim 4
Dependent Claim
79 words
The invention as defined in claim 2, wherein said means to urge said pin comprises a lever that is hinged from said pin at a predetermined point therealong at one end of said lever, the other end of said lever being movable by said safety valve, projection means on said pin, a spring coiled around said pin compressed between said projection means and said valve body, and fulcrum means fixed to said valve body for engagement with said lever.
Claim 5
Dependent Claim
79 words
The invention as defined in claim 1, wherein said means to urge said pin comprises a lever that is hinged from said pin at a predetermined point therealong at one end of said lever, the other end of said lever being movable by said safety valve, projection means on said pin, a spring coiled around said pin compressed between said projection means and said valve body, and fulcrum means fixed to said valve body for engagement with said lever.
