GAS-BURNER.

' SPECIFICATION forming part of Letters Patent N 0. 778,104, dated December 20, 1904. Application filed March 24, 1904. Serial No. 199,814.

In Figs. 1 and 2 we have shown the strip 7 provided with an inner reinforcing-strip 23. Thisinner strip is formed of material which will rapidly expand when subjected to heat, thus insuring the lateral movement of the strip 7 when the gas is ignited.

In the foregoing description we have shown the preferred form of our invention; but we do not limit ourselves thereto, as we are aware that changes may be made in the form, proportion, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention, and we therefore reserve the right to make such changes as fall within the scope of our invention.

Having thus described the invention, what is claimed as new is 1. The combination with a burner having a slide-valve therein, of a thermostat extending over the burner and connected to the valve, an arm extending from the thermostat, and a valve-opening lever connected to the burner and separate from but adapted to engage the arm to lock the valve in opened position.

2. The combination with a gas-burner having a slide-valve therein, of a slotted thermostat secured to the burner and extending thereover, said thermostat engaging the valve, a hooked arm extending from the thermostat, a springcontrolled lever connected to the burner, and a hook upon the lever for engaging the arm.

3. A burner comprising a tube having a tip on one end thereof, a plug within the tube having a passage therethrough, a slide-valve within the plug and tube and normally closing the passage, a longitudinally-slotted bowed thermostat secured to the tube and extending over the tip, said thermostat having a slotted end adjustably connected to the valve, a ring secured to the thermostat and loosely inclosing the tube, and a pivoted lever connected to the tube and adapted to operate the thermostat to open the valve.

4. A burner comprising a tube having a tip on one end thereof, a plug within the tube having a passage therethrough, a s1 ide-valve within the plug and tube and normally closing the passage, a longitudinally-slotted bowed thermostat secured to the tube and extending over the tip, said thermostat having a slotted end adjustably connected to the valve, a hooked arm, extending from the thermostat, and a spring-controlled hooked lever mounted upon the tube and adapted to operate and engage the arm.

5. A burner comprising a tube having a tip on one end thereof, a plug within the tube hav ing a passage therethrough, a slide-valve within the plug and tube and normally closing the passage, a longitudinally-slotted bowed thermostat secured to the tube and extending over the tip, said thermostat having a slotted end adjustably connected to the valve, a hooked arm extending from the thermostat, a loop inclosing and pivoted upon the tube, a hooked arm extending therefrom and adapted to bear upon and operate the arm of the thermostat, a spring connected to the loop, and an oper ating device depending from the loop.

6. A burner comprising a tube having a tip on one end thereof, a plug within the tube having a passage therethrough, a slide-val ve within the plug and tube and normally closing the passage, a longitudinally-slotted bowed thermostat secured to the tube and extending over the tip, said thermostat having a slotted end adjustably connected to the valve, a ring connected to the thermostat and loosely inclosing the burner, and means for operating the thermostat to open the valve.

7. A burner comprising a tube having a tip on one end thereof, a plug within the tube having a passage therethrough, a slide-valve within the plug and tube and normally closing the passage, a longitudinally-slotted bowed thermostat secured to the tube and extending over the tip, said thermostat having a slotted end adjustably connected to the valve, a ring secured to the thermostat and loosely inclosing the tube, a collar secured to the tube, a hooked arm thereon, a loop pivoted upon said collar and inclosing the tube, a hooked arm thereon, a hooked arm upon the thermostat adapted to be engaged thereby, a spring connected at opposite ends to the loop and the arm of the collar, and an operating device connected to the loop.

In testimony whereof we ailix our signatures in presence of two witnesses.
