The strut9 is somewhat pointed at both,

My invention relates to automatic fire-extinguisher systems, and particularlyto the devices for preventing the escape of the fluid until the devices are made to operate by the I I efiects'of heat. y
The object of the invention is to increase the efiiciency and durability of the device byproviding an operating mechanism composed of re silient'non-corrosive metal and do away with 03.8111 8 or pockets in whlch dirt a I or dust might collect and interfere with the reliability of the device.
To this end I employ resilient operatin devices that are restrained from action by a fusible link for holdings. cap or'valve on the fluid opening and which are adapted upon the fusing of the link to s ring out of'the way and permit the fluid to ischarge.- 1
My improvements are illustrated in the accompanying drawin s, in which- Figure l'is a front e evation of the fire-exmy improvements and showing all of t e parts assembled inposition to restrain the flow of the fluid; Fig. 2 is a centralvertical section on i the line A-A of Fig.1; and Fig. 3 is a horizontal section on the line B-B of Fig. 1.
- Inthe drawings 1 desi hates the hollow bushing throu h which t e .fluid may discharge, and wfii'ch, by means of the screwthreads 2, is connectedwith a pipe of the distributing system; 3. is the nozzle portion of the bushing: 4 a disk thereon; and 5 a cap seated on the disk. I I
YEA link 6' of 'material that is fusible at, suitably low temperature engages a strip of resilient metal and holds it in contact-with the strut 9 that presses the ca 5 to its seat. The resilient strip 7 is secure by pins 8 to the depending resilient arms of a U-shapedends, the lower point seating on the cap 5 and the u per bearing against thehorizontal portion 0' the lever 10. The upper surface.
of the lever bears against the wedge-shaped under surface 12 of the frame.
In use, the'headhavin been connected to va fluid pipe, when the ink 6 is fused the spring bar 7 is released and its resilience will t now the arms of the U-shaped lever laterally and thus free the -strut and permit the fluid to lift the cap and flow from the nozzle 3. A deflector 13 on the top of the frame serves to distribute the fluid.
Having described my invention, what I claim and desire to secure by Letters Patent 1s 1. A sprinkler head, comprising a nozzle, a
cap therefor,an open frame formed on the nozzle and having a wedge-shaped inner surface op osite the nozzle, a resilient U'-shaped lever t e body of which bears against said wedge-shaped surface, a strut engaging said cap and lever body, a spring connectin the ends of the lever arms and a fusible lin for flexing said arms and spring and connecting them to the strut, substantially as set forth.
2. Asprinkler head, comprising anozzle, a cap therefor, an open frame formed on the nozzle, a U-shaperl lever loosely seated on said frame opposite the nozzle and having resilient arms a strut engaging said cap and ,lever body a spring connecting the ends of the lGVfil'J runs. and a fusible link for flexing said arm's and spring and connecting them to th Si ru t, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses this 25th day of April, 1907. g.
