MODEL INCUBATORS AND BROODERS FOR 1909 



Model Heater Fire-Proof. 



Ordinarily should a careless operator lo;ivo too high a tiame 

 and it should draw up to a smoking point, the aeeunuilation of smoke 

 in the heater under its particular construction will in a short time 

 smother out the lamp tiame. A screen in the chimney flue 

 above the flame will reduce the time of such action to about fifteen 

 minutes, but such an extendeil time blackens and anneals the burner 

 iintil it is practically spoiled, so that such carelessness and haste 

 costs the oi>erator a new burner. The possibility of a lamp explosion 

 with the present commercial oils is exceedingly remote and the 

 construction of the ^lodel Heater is such that any aniouiit of heat 

 generateil by the lamp tiame cannot set fire to any portion of the 

 Incubator. 



Fusible Link 



With the XewModel Attachment. within one or two minutes after 

 the lamp flame smok»^ and before the burner can b<vonie heated, 

 a small fusibb* link attached to the ba.se <if the chimney part of the 

 heater is melteil and releases the flame extin«ruisher. which puts it 

 nut instantly. This is on the same principle as the link used in 

 sprinkler sj-stems, and to hold fire doors open. I'te.. for safety pur- 

 poses in large mercantile and factory buildinors. If. in twelv,' years' 



constant us<> of thou- 

 sands of ^fodel Incu- 

 bators, the heating 

 system has failed to 

 set fire to a .single 

 machine, surely the 

 atlflition of this safety 

 device carries it be- 

 yond the last possi- 

 bility of an accident. 



mane Lamp Feed 



The .Model Patent Automatic Lamp Feed. 



Another device for 190S-9 is an automatic attachment whereby 

 the lamp fount is reduced to a diminutive size and is kept auto- 

 matically filled from a barrel or tank, which can be placed at a 

 distance, or even outside of the incubating room. This is a labor
