CHARLES E. BUELL, OF NORTH PLAIN FIELD, NEW JERSEY. v
AUTOIM-ATIC SPRINKLER;
SPECIFICATION forming part of Letters Patent No. 570,901, dated November 10, 1896.
Application filed May 25, 1896. Serial No. 593,083. (No model.)
To aZZ whom it may concern.-
Be it known that I, CHARLES E. BUELL, of North Plainfield, Somerset county, State of New Jersey, have'invented Improvements in Automatic Sprinklers, of which the following is a specification.
' In the drawing there is shown an automatic sprinkler having a plate q covering the outlet, with a gasket q between the plate q and nozzle n. Upon the plate q is a spring 3, consisting of a strip of metal bent back upon itself and adapted to interlock with, the plate q to prevent slipping. Upon this spring is placed a strut consisting of an upright member 2 and a supported member 1, pivoted thereon out of line of the longitudinal axis of the upright member and involving leverage when the upright member and the supported member are pressed together into the position shown in the sprinkler S. Each member is provided with a deflected portion, and the contacting surfaces of the two members are soldered together. A slot is shown in member 1 at e and a pin or struck-up projection e in member 2, registering with the slot e and entering into it, and fusible material so placed in the slot and in front of the projection e as to be in the pathway of the projection as the same would move when the members separate. Solder is also placed at the pivotal point of the two members at 00. By thus interposing fusible material in the path of a projection the strut is considerably strengthened.
What I claim is 1. A sprinkler having its outlet held normally closed by a valve that is held to its seat by a strut consisting of two members, an upright member and a supported member pivoted thereon out of line of the longitudinal axis of the upright member, the said members being soldered together along their contacting surfaces, and a projection upon the deflected portion of one member entering into a slot in the other member, and fusible material interposed in the path of said pro j ection.
2. A sprinkler having a fusible fastening comprising an upright member and a supported member pivoted thereon, deflected portions for each member, and a projection upon the deflected portion of one of said members that registers with a slot in the other member, and a fusible material interposed in the path of the members through which they would move in being separated.
3. A sprinkler having a valve'covering its outlet, a fusible fastening comprising interlocked members having fusible material interposed in the path through which said members move when released, and a spring in the structure for giving athrust to the released fusible fastening that is composed of a strip of metal bent back upon itself and adapted to interlock with the Valve.
4. An automatic sprinkler comprising a fusible fastening consisting of a supporting member having a portion thereof removed for reducing the mass to be heated, a deflected portion having a projection struck up thereon, asecond member pivoted thereon, a deflected portion, a slot in the upright and deflected portions thereof through which the said projection passes, and fusible material interposed in said slot.
5. An automatic sprinkler comprising a fusible fastening consisting of a supporting member and a supported member pivoted thereon, a deflected portion on each of said members, a projection on one of said members protruding into and through a slot in the other of said members, fusible material in the path of the interlocked members where the projection passes through the slot and also at the point where the supported member is pivoted upon the supporting member.
6. A strut consisting of a supporting member and a supported member pivoted thereon, a deflected portion on each member, a slot in the deflected portion of the supported member, and a struck-up projection on the deflected portion of the supporting member registering with said slot and entering in and passing through said slot at a point slightly in front of the upright portion of the slotted member, and, fusible material between the projection and the upright portion of the slotted member.
