thermometer orl support being shown removed from the incubator, and f t Fig. 10 is a detail perspective view of the forward end of the movable element which operates the dampers. v

Referring to the drawings in detail,fthe incubator is shown as consisting of a casing having formed therein an upper compartment 2, an intermediate compartment, and

a lower compartment 4. The walls of the incubator are formed in the usual or any appropriate manner. The front of the incubator is closed by an inner and outer wall, i

the inner wall having formed therein an upper door 5,'which opens into the upper end of the intermediate compartment 3, an intermediate door 6, which also opens into the intermediate compartment 3, and a lower door 7which 1closes the forward side of the lower compartment 4. `These doors 5, 6, and` 7 are hinged, respectively, to strips 8 and 9. The outer wall consists of a door 10, which has hinge connection to one of the side walls of the casing, and the-door 6 in the inner wall is provided with an opening 11 which receives asuitable lens, the said opening y11 being adapted to register with a similar opening 12 formed in the doorlO, when the latter is in closed'position, and within which is mounted another lens. The openings 11 and 12, and the lensesmounted therein, serve to provide a windowby which the interior of the intermediate compartment 3 can be inspected. The upper wall 10 is hingedly secured in position and forms means whereby access may be readily had tothe upper portion of the incubator. The opposite side i walls of the intermediate compartment are provided with opposed ledges 13 which form rests for an egg tray, designated` 14, in Fig. 2 of the drawings. The upper wall of the intermediate compartment 3 is provided with a pair of-spaced openings l5, and the lower wall of the intermediate compartment is also provided with a pair. of spaced openings 16. VThe uppercompartment 2. and the lower compartment 4 constitute the heating compartments ofthe incubator and by virtue of the openings l5 and 16V formed in the upper and lower walls of the intermediate compartments the heatcan pass fromthe upper and lower compartments 2 and 4 into the interi'nediatey or egg compartment 3. Each of the compartments 2 and 4 has and lower compartments.

partment, designated 19, is adapted to re-.

ceive hot water, and the upper compartment receives a heating element 20, formed, preferably, of soapstone, or other material which Y will readily absorb heat, and .heat the water in the lower compartment 19. The comparta ment 18 is provided, at a medial point, with an opening which receives one end of a fill-` ing spout 21. This filling spout 21, as shown in F ig. 4 of the drawings, consists of a tubular body havingy its upper end closed by a.

removable disk 22, which has a central opening-therein, and mounted within the spout,

andmovable therein, is a Adisk 23, having an opening 24 therein, which is disposed indirect alinement with the opening in the disk v22. A coil spring 25is interposed between the disk V22 and the `disk 23 and serves to hold the disk 23 spaced below the disk 22. An annularianged member 26 is threadedlv mounted within the filling spout 21 and engages the lower side of the disk 23, and has its lower side provided with a plurality of openings 27. rIhe disks 22 and 23, andthe element provide a whistle that will be opere` ated to'give a sound when the water within the tank 171becoines heated to the degree where steam 'will be generated, the vsteam generated passing through the openings in the disks 22 and `23 and the flanged element 26,'and producing a sound. A flanged cap 28 engages over the disk 22 and has threaded engagement with the upper 'end of the spout 21, and serves to retain'the disk 22 in operative position, the upper side of the cap having an opening 29 therein for the escape of the steam. A pair of handles 31 are pivotally connected to the sides of the heater, as at 30, and the handles form means for the easy removal of the heater. I he lower 'conipartment 4 has one 'of the end walls thereof provided with an air inlet opening 32, and a manually operated damper 33 is adapted to regulate the passage of air through the opening 32 into the lower compartment 4.

A pair of rectangular shaped dampers 34 underlie the upper wall of the intermediate compartment 3 and arey adapted, when the heat within the intermediate compartment 3 exceeds a predetermined degree to move upwardly andvclose theopenings 15, so as to cut oi' communicationbetween thel upper or heating compartment 2 and the intermediate compartment 3. These 7dampers 34 have their forward ends connected by a bar 35, which is of kangularshape in cross section, and the rearpends of the dampers 34 have openings therein'for the reception of the bills of hooks 36, which are secured to the rear wall of the intermediate compartment 3.v A bracket 37'is located within the intermediate compartment 3, and is of angular shape and has one legthereof secured to the rear wall of the intermediate compartment another thermostat 41 composed of a single y wafer. An expansion bar 42, of arcuate shape, has its opposite ends overlying and resting on the respective thermostats 40 andV i 41, and when the' thermostat expands, thel rod 42 will be raised upwardly'. The rod 42 is received between pairs of spaced studs 43, which project vertically from the bracket 38. A wedge shaped element 44'rests upon the upper side ofthe rod 42 and is provided with a longitudinally extending channel 45,y

the lowervwalll Aof which is inclined toward the restricted end of the element 44. An elongated horizontally disposed and .verticallymovable element 46 isdisposed above the element 44 and has its opposite sides provided with upwardly extending elon-rv gated flanges 47, which are provided' adjacent their rear ends with opposed openings through which passes a transverse shaft 48,`

`the opposite ends ofthe shaft 48 extending beyond the outer sides ofthe iiangcs 47 and Journaled in the sides of the inverted Uf shaped frame 49, which is secured to the y under side of the upper wall of thekintermediate compartment 3. A verticalpin 50 has-its upper end extended through an opening in the movable element`46 at a pointin advance of the shaft 48, and a pin 51 vextends through an opening in the upperend of the pin 50 and is journaledin the flanges 47. The lower end of the pin 50`extends into the channel y45 formed `in the element 44, and is provided with a head, which pre-vl Vents the lower end of the pin 50 from being raised vertically out of the channel 45 by engaging opposed inwardly directedanges formed on the upper walls of the channel 45, as shown more particularly in Fig. 2 of the drawings. Located within the intermediate compartment 3 anddisposed in rear of thel bracket 38v is avertical rod 51a,*which'has the upper end thereof bent to provide a lloopvwhich is extended through an opening vllfl Elfi in the rear end of the plate 46. The rod 51a is slidably received by an opening formed in thehorizontal arm of the bracket 37. A

horizontal rod, designated 52, is located -at the forward end of the plate 46 and has one end extended through an opening in the vertical flanged portion ofthe bar and terminally extended therebeyond, andy the opposite. end 'of the rod 52 extends through a sleeve formed on the forwardvend ofthe f plate 46 by a longitudinal depression in the plate, the terminal of the mentioned end of the rod 52 being coiled'V and fitted yin a circular recess formed in .the-upper, side of the plate 46, the said circular recess being disposedxin concentric relation with the opening which receives the` upper end of the pin 50...An operating rod 53 is slidably extended through one of the side walls of the casing and has the inner end thereof connected to theelement 44, and the opposite end located exteriorly of the incubator and provided with a manipulating head 54. When vthe temperature in the intermediate compartment exceeds a predetermined degree, the thermostats 40 and 41 will expand andv Cause the rod 42 and the. element 44 to besmoved v,upwardly and effect engagement between the lower wall of VTthe channel 45 and the lower. end of thel pin 50, and coni tinued upward movement of. the element 44 willlrock the forward end of the element 46 upwardly, andcause the rod 52 to be moved upwardly andzeffect closing of the dampers 34,. thereby cutting yoif. communication between',` the heating compartment 2 and the intermediateicompartment 3. When the rod 53.*is Amoved inwardly the enlarged end of thel element 44 will be brought nearer to the highest pointfon the curved surface of the rod'42 .and the lower wall of the channel 45 willbe brought nearer to the head of the pin 50, thereby admitting of the dampers being closed upon less degree of expansion 'of the-thermostats 40 and 41, than it takes to operate the dampers when the restricted endof the element 44'is presented to the highest' curved point on the rod'42. It will, therefore, be seen that the element 44 will :serve as a regulator to effect closing of the damper at any desired temperature. The lower end of the vertical rod 51Va carries a section 51", which has adjustable connection with the rod 5la by means of an adjusting nut 51e. The section 51b yhas connection with the inner end of a horizontally disposed lever v55, the said 'lever being pivoted to a bracketf56 mounted on the lower wall of the intermediate or tray compartment 3, at avpoint-in rear of the openings 116. The forward endof the lever 56 has connection with a rod 57, which extends at right angles to the lever and has secured to the opposite ends a'pair of dampers 58, which overlie the Ai openings 16 in the lowerwall of the intermediate compartment. When the thermostats 40l and 4l are expanded to effect movement of the'dampers 34 to closed position, the vertical arm 5la will be pulled upwardly l Si and effect. the lowering .of the forward end an opening 60 formed in the adjacent wally of the lower compartment 4. The. upper end of the flue 59 is closed by a. wall 61,1 which has an opening 62 therein. A tubular shaped support 63 is secured to the. wall 61 and has its upper end provided with an offset pair of spaced arms 64. A lever 65 is pivoted between the arms 64 and has one end connected to the upper end of a vertical stem 66 carried by a damper 67 which overlies the opening 60 in the wallL 61. When the lever 65 is moved inone direction, the .damper 67" will close the opening 60, so as to prevent entrancey of air into the flue 59. A weight 68 is adjustable on the free end ofthe lever 65, for the purpose of regulating the amount of force for rocking the lever 65. A rod 69 is operable through the tubular support 63 and-has its upper end connected to the lever 65, at a point inI rear of the fulcrumthereof, and the lower fend of the rod 69 extends into the flue 59 and has connection with the ou ter end of a horizontally disposed rod 70, which extends through an elongated slot formed-in theadjacent wall of the intermediate ycompartment 3 and has its inner'end extended through the bifurcated endof an arm 72 carried by the adjacent arm 39 of the bracket 38. The inner terminal of the rod 70. is bent downwardly, as shown atA 71, and overlies that end of the bar42 which rests upon the uppermost wafer of the thermostat 40. When the thermostats 40 and 41 raise the rod-42, thev rod will engage the bent terminal 71 of the rod 70 and raise the inner end' of the rod 70 upward, causing the outer end to pull the rod 69 downwardly and cause' that end of the rod 55 which has connectionwith the stem 66 of the damper 67 to be'raised upwardly, so as to raise the damper 67 above the opening 60 and admit of entrance of air into the flue 59 and thence through the opening 60 to the lower compartment 5.

In Fig." 1` of the drawings a brooder, des-y ignated as an entirety by the numeral 73, is shown associated with t-he incubator and located at the side opposite the one having the' flue 59. The supporting brackets are located on Vthe opposite sides of the brooder 73 i for supporting the brooder and each consists of a V-shaped element 74, lwhich hasthe free ends ofk its sides connected with the incubator by means of suitable plates 75. The

' apex of the V-s'haped' bracket 74 has connecaround theforward side 4of the brooder andl the opening in the secured thereto by means of a set screw fastening element 7 7.' The brooden 7 3 has that Wall adjacent the incubator provided with an opening that registers with an openingl 78 iny the incubator wall so as to communicate the interior of the broodel` with the intermediate or egg compartment 3 of the incubator. `Anair iiue 7 8 is provided for the brooder and the entrance of air into the brooder therefrom s controlled by a suitable -valve (not shown). Y.

f Located Within the intermediate or egg compartment 3 is a thermometer 79. This thermometer 79, as shown in Fig. 1, is disposed directly opposite the windows in the front wall ofthe intermediate or egg compartment 3 and the said thermometer is, as shown in Fig. 9, carried by a laterally eX- tending bracket`80, which has its outer end provided with a sleeve 81. This sleeve 81 receives the upper end of the outer slidable member of a vertically disposed telescoping support 82, the said sleeve 81 -being secured to the` support by means of a fastening'ele'-y ment 83, which extends through the sleeve and engages the adjacent end of the support. The lower end of the inner member of the support'is bent laterally to provide a supporting foot 84, which rests upon the lower wall of the intermediate or egg compartment 3 .and is secured thereto by means of. fastening elements 85. The outer slidable member of the support is adapted to be held in adjustable position by vmeans of a `set screw 86 that is adjustable through the outer` member 'and through the inner member, yas

shown in Fig. 9 vof the drawings.Y The eX-.

tended terminal of the forward end of the rod 52 engages beneath a bowed spring 87` and extends over the bill of a hook 88, which hook depends from the upperV intermediate compartment 3. The spring 87 exerts a downward force on the adjacent end of the rod 52 and an upward forcelon the forward ends of the dampers, so as to cause the rod 52 to engage the lower wall of flange 35, and spaced. from the upper wall of the said opening.

wall of the This is advantageous in that when the dam-` pers are in closed position any further expansion of the thermostat will result in the movement ofthe forward end of the rod 52 against the tension of the spring 87, which spring will give under the upward movement. of the rod and thereby prevent injury being done to the rod 52. The hook 88 engages the adjacent terminal of the rod `52 when the dampers are moved downwardly, and limits f the `downward movement of the dampers.

It is evident that various changes may be resortedto in the construction, form and arrangement of the several parts without departing from the spirit andscope .of the invention; hence I do not limit myself strictly YHaving thus 'described my what I claim asnewr, is:. f .I
