To'aZZ 'whom it may concern: j

Be it known that T,llnivn'iin llhmdan,

' a citizen otl the? 4United States, residing` at 'New Yorkcity.. in the county` ot New -York andState' of New York,l have invented eertaln nei' and useful'linproveineiits in llxpansible Mechanism `for [1)ainper-Regulators,

` ot' which the following is a speeitication.

The invention relates to improvements in expansible ineehaiiisin fforftliiid heating danip'er regulator apparatus and'has -par-A tieular reference to that ty'ietof`:eXpansihle mechanism consisting,` ot' a eo'n'voliitetlv sheety inetal pipe havingi'ornied therewith'a. depending chamber adaptedlto'iin "L a de-- pending' bulb or chamber siibi'iierl `d ,in the line'ot the fluid circulation ot a Huid heat` inf; generatoi.' tor receiving the initial forces' ot said fluids under pressure 'to act ii'poi damper controlling"means.

A further objectl ot 'the` invention. iwsthei providing ot a secondary e'xpan: `e`. means' comprising a coin'oliited 'pipe'o't a resilient material such as a molded form provided with a predeterminedfnumber of" convolutions ot hard rubber orot al similar sub` stance adapted'to act in connection with `a primary expansible means preferably of the well known type ot" metallic expansible Structure.

=What l claim: dadesire to secureby Letters Patent-otl tlicUhited States is:--

1.`- A device ot the character described comprising a damper regulator supporting easing' having' formed therein a fiuid chamber and tluid pipe reception means, an ex? egulator controllingV pansible mechanism reception chamber depending in .said fluid chamber formed in saidA casing, a pipe adapted for expansion having formed on its lower end a supporting base adapted to engage said reception chamber in said. casing and vhaving its upper body portion formed into a plurality of convolutions, a cap having cast integrally therewit-h an actuating pin adapted to engage the a supporting base and inits upper body por-` extreme upper convolution in said pipe, and a hood surrounding sa1d expansible pipe provided with an aperture adapted to receive the pin on said cap.

2. A device of the character described including an expansible pipe for damper regulators having formed on its lower closed end yactuating pin, a hood engaging said casing and adapted to `surround the convoluted portion of said expansible pipe, the lower closed end vof said expansible lpipe being so arranged with relation to the reception chamber as to form a supporting base or wall for chamber the upper convoluted portion of said piper 3. A device of the character described, comprising an expansible tube, a fluid cham ber' with fluid pipe reception means, a chamberprojecting into said fluid chamber substantially as set forth, and provided with a closed Wall interposed between the iiuid and theiiiterior of the chamber` projecting into the lfluid chamber, whereby itlwill be surrounded and acted upon by the fluid-entering the fluid chamber, a hollow extension projecting from the expansible tube and entering and fitting closely within the chamber projecting into the fluid chamber, but removable therefrom as described, without opening the pipe or its chamber, and means connected with said expansible tube for operating/a regulating device, all substantially as set forth. i

4. A device of the character described,

comprising ail expansible tube, a fluid chamber with iuid pipe reception means, a chamber projecting into said fluid chamber substantially yas set forth, and provided with a elosedgwall interposed between the fluid chamber and the interior of the chamber projecting intothe fluid chamber, whereby itwill be surrounded and acted upon by the fluid entering thefluid chamber, a hollow extension projecting from the expansible tube and entering and fitting closely within the chamber projecting into the fluid chamber, but1 removable therefrom, as described, without opening the pipe or its chamber, a cap closing the outer end of the cxpansiblc tube and provided with a pin extending therefrom all substantially as set forth.

5. A device of the character described, comprising an expansible tube, a fluid cham# ber with fluid pipe reception means, a chamber projecting into said fluid chamber substantially as set forth, and provided with a closedl wall interposed between the :lluid chamber and the inteiior of' t-he chamber projecting into the fluid chamber, whereby it will be surrounded and acted upon by the fluid enteringthe fluid chamber, a hollow extension projecting from the expansible tube and entering,and fitting closely within the chamber projecting into the fluid chan'i-v ber, but removable therefrom, described, without opening the pipe or its chamber, a cap closing the outer end of the A exj'iansible tube and provided with a pin extending -therefrom, and a casing apertured for thc passage of said pin, and surrounding said expansible tube all substantially as set forth. 6. A fluid conveying pipe, provided with a fluid chamber therein, closed at the sides, a

`chamber projecting into said fluid pipe chamber substantially as set forth, and provided with a closed wall interposed between the fluid. chamber and the interionof the chamber projecting into the fluid chamber, whereby it will be surrounded and acted upon by the fluid entering the fluid chamber, an expansible tube, a hollow extension projecting. from the expansible tube and entering and fitting closely within the chamber projecting into the fluid chamber, but removable therefroin' described, without opening the pipe or its chamber, and means connected with said expansiblc tube for op erating a regulating device, all substantially as set forth. v
