' The thermostatic element 35A is carried by a block 36 which is seated in the end of the arm 30 against the shoulder 37 and clamped in position by the plug $8. The fulcrum block 39 is pivoted at 40 within the tubular' arm 30, otherwise the structure is substantially the same as that of Figs.'I, II and III.
I have not attempted to illustrate or describe certain other modifications and adap- ,tations of my invention as I believe the disclosure made will enable those skilled in the art to which my vinvention relates to embody or adapt the same as may be de- I claim as new and desire to secure by Letters Patent, is:

2. In a thermostat, the combination of a coupling member externally threaded to engage a support, a housing tube t/hreaded 1nto the inner end of said coupling member, a valve casing having threaded engagement with said coupling member and provided with an arm projecting into said housingtube, and a thermostatic element mounted at the inner end of said arm.
3. In a thermostat, the combination cia coupling member, a housing tube threaded into the inner end of said coupling member a valve casing and valve, an arm on sai valve casin comprising a tubular outer portion threa ed into the outer end of said cou ling member and an inner portion projectmg into said housing tube, a thermostatic element mounted on the inner end of said arm and operatively associated with said valve, a fulcrum member for said thermostatic element pivotally mounted on said arm adjacent its inner end,`and an adjusting screw for said block disposed longitudinally of said arm.
4. In a thermostat, 'the combination of a coupling member, a housing tube threaded into the inner end of said coupling member, a valve casing and valvean arm on said valve casing comprising a tubular outer portion threaded into the outer end of said coupling member and an inner portion rojecting into said housing tube and constituting a thermostatic element support, and a laminate thermostatic element mounted on the inner end of said arm and operatively associated with said valve.

In a thermostat, the combination of -a valve casing and valve, an arm on said valve casing, a laminate thermostatic element having a fixed mounting on the end of said .arm to coact with said valve, an adjusting fulcrum pivoted on said arm to coact with said thermostatic element, and an adjustin screw threaded into the outer wall of sai valve casing and disposed longitudinally of said arm to engage said adjusting fulcrum `adapted for adjustment 'from outside the valve casing.
8. In a thermostat, the combination of a valve casing and valve, an armvon said valve casing, a laminate thermostatic element having a `fixed. mounting on the end of said arm to coact with said valve, an adjusting fulorum mounted on said arm to coact with said thermostatic element, and an adjusting screw disposed to engage said adjusting fulcrum adapted for adjustment from outside the valve casing.
'having a fixed mounting on the inner end of said arm in operative relation to said valve, an adjusting fulcrum for said thermostatic element disposed adjacent its inner end, and an adjusting screw for said fulcrum disposed longitudinally of said arm and adapted for adjustment from outside the valve casing.
10. In a thermostat, the combination of a valve casing provided with a valve, a lain-V inate thermostatic element supporting arm on said casing, a thermostatic element'having a fixed mounting on the inner end of said arm in operative relation to said valve, and an adjusting fulcrum 'for said thermostaic element disposed adjacent its inner en 1l. In a thermostat, the combination of a valve, a laminate thermostatic element supported at one end with its free end operatively associated With said valve, said thermostatic element having an angular cross section, there being a fiat central portion, side portions at each side disposed at a slight angle thereto, and an adjustable fulorum member engaging the rear side of said element adjacent its mounting.
12. In a thermostat, the combination of a valve, a laminate thermostatic element supported at one end with its free end oper atively associated with said valve, said ther- `mostatic element having an angular cross section, there being a 'lat central portion, and side portions at each side disposed at a slight angle thereto.
13. A thermostat comprising a laminate thermostatic element of angular crosssection, there being a central portion and side portions at each side disposed at an angle substantially less than a right angle, a supporting means clamping one end of said element, a fulcrum member engaging the rear side thereof adjacent said supporting means7 and means for adjusting said fulerum member.
14. A laminate thermostatic element of angular cross section having a flat central portion and side portions disposed at a slight angle thereto.
