of the regulator to be actuated simultanea ously therewith, and. i

Fig; 4 is a -fragmentary sectional View particularly illustrating' 'the detachable mounting Iof the .lever arm .lof the thermostat of the regulator.

In order that the construction, mounting and operation of my improved regulator' may be 'accurately understood I have, in Fig. 1 of the drawings, shown-the. device in connection with a conventional.:typeofjin`- cubator 10 provided with an e g chamber Y11 and equipped with a lamp ue 12 from the lamp casing 13 of the incubator. In

carrying out the invention` I employ complem'ental lever Stands 14 which are mount..

#ed upon the top of the incubator in any approved manner. One of these standsis shown in detail inv Fig. 2. Mounted upon the said stands are coacting regulating levers 15and-16 respectivel These levers include Yf ulerum members l; and 18 respectively through'which extend rods 19 engaged through' ears 20'upon the stands 14 and pivotall'yfconnecting the said members withthe stands. Asparticularly shown in Fig. 1, theflevers" 15a11d. 16` 'each include a long arm andja* shorterm. For convenience, the shorter arms of the said levers have v been indicated at 21 and 2 2 respectively. Connected to the longer arm ofthe lever 15 isy adamper 23 arranged to close a suitable vent iiue from the egg chamber- 11 ofthe-in cubator. The longer arm ofthe lever 16 is equipped with a 'similar'.l damper 24er-4 ran ed to close the lamp ue 12.` T 'e shorter'larm 21 of th lever 15- is preferably formed from a length o f'suitahle resilient-.wire bentv intermediate its e dsl to prcvfde'a pivotloop' or connecting'.` m er levereland gs'glecoun. .1^ CerniaV lengin anyapprpved 'manner with the" Stands enga-viera@ hiel. loop.. serves-j te4 pivot-',;

l ed upon the stud 33 projecting into the egg chamber 11 and connected at their 'lower ends by a cross bar 30 t0form a supporting frame fourths, thermostat'. Mounted upon the said bar is a thermostat 31 )referably formed of coacting wafers. rejecting from one side of the thermostat is a stud threaded through the bar 30 for detachably connecting the thermostat with the said bar. jecting from the opposite Side of .the thermostat is a similar stud Screw threadis a cross head 34, which is thus detachably connected with the thermostat. At its extremities, the cross head 34 is iven a half turn and is provided with suitabqe openings. Detachably engaging through these openings are connecting rods 35 which extend within the posts 29 of the supporting frame for the thermostat and project through the fulcruin members 17 of the levers '15 and 1G. Screw threaded upon theupper extremities of the said rods are adjusting' nuts 3G.

lAs will now be readily understooifl, the thermostat 3l will, of course, expand as the temperature of the egg chamber 11 rises. Expansion of the said therin-ostht. will move the cross head 34 downwardly and accordingly simultaneously pivot the regulating levers i4 and 15 to raise the d ainpers 0 pivotally .i3 and 24;. Since the levers are connected at their inner ends, the said levers will always move in unison and by adjusting the nuts 36, the temperature at which the dempers 23 and 24 shall be raised, may

' be easily varied.

It. will therefore be seen that I provide a particularly simple, and ellicientl construction forv the` purpose. set tort-li. In this` con-- nection, particular attention is directed to the facty that should the cross head 3l ot' the thermostat become broken or its elliciency ntheru-'ise 'in'ipaireih the connecting rods 35 inav be disengaged from the said cross head when the cross head may be detached by Simply unscrewing it from the post of the thermostat` This` provides a1 convenient arrangement whereby the cross head may be quickly renewed or repaired.

In Fig'. 3 of the diraAvingsJ ha ve'illustrated the manner in which an auxiliary regulating lever may be employed ais a part of my improved regulator. ln this [igurc an incubator has been conventionally shown at. 37. Mounted upon the top wall of the incubator are the lever stands 1l carrying the regulating-levers l5 and lo connected at their inner ends` by the pivot. loop 25'. pers 237 and 24 of these levers are respectivelyarranged to close, a. vent flue 'leading to each of the egg chanibers of tl'ieincubator.
