TH ERMOSTA'l' FOR INCUBATORS.
SPECIFICATION forming part of Letters Patent No. 433,910, dated August 5, 18 90. I I Application filed November 23, 1888. Serial No. 291,716. (No model.)-
To all whom it may concern.-
Be it known that I, FRANK SAUMENIG, a cltlzen of the United States, residing at Springfield, in the county of Clark and State.
construction being such that the sides and corners are heated to an even temperature with the center portion of the incubator.
A further object of my invention is to provide a sensitive and accurate temperatureregulator.
My invention consists in the various constructions and combinations hereinafter described, and pointed out in the claims.
In the accompanying drawings, which form a part of'this specification, Figure 1 is a perspective view of a device embodying my invention. tion view of the same. Fig. 1 is a detail. Fig. 3 is a plan view in detail of a portion of the temperature-regulating device. Fig. 4 is a detail view in perspective of the lamp-regulating device. Fig. 5 is a vertical sectional elevation View through the side circulating tubes. Fig. 6 is a horizontal sectional view showing the arrangement of the circulatingtubes and evaporating-pans.

Like partsare indicated by similar letters of reference throughout the several views.
In the said drawings, A A represent the outer casing of the device, preferably supported on suitable legs a.
B is a boiler, to which heat is applied by a suitable lamp B, preferably supported on a bracket B attached to the bottom of the outer casing A A. The lamp B is provided 2 is a vertical sectional elevawith a chimney B, which projects upwardly into a chamber B in the boiler B. Extending each way from the chamber B and passing longitudinally through the boiler Bare smoke-fines a, which pass through the ends of the boiler B and project upwardly, as shown in Figs. 1 and 2.
Located Within the casing A A, near the top thereof, is a reservoir 0, the outer perimeter of Whichis slightly smaller than the inside of the casing A A. The reservoir 0 is connected directly to the boiler B at the front corners of .the casing by the circulating-tubes tending across the incubator at the sides and bottom and join the front tubes 0. (See Fig. 5.) Near the center of the rear portion of the casingA Ais a small vertical tube 1), con- O O and at the rear corners by tubes 0 C which connect with longitudinal tubes 0 exforwardly along the bottom of the casing A A,
to the boiler B, the tube 1) being dropped down, asshown in Figs. 5 and 7, so as to enter the boiler B at the bottom thereof. The reservoir 0 is filled through an I opening b provided with a suitable screw-top or other fastening, thus filling the circulating-tubes and the boiler.
Extending transversely across the casing A A and just below the reservoir 0 is a shelf D, on which is located the temperature-regulator. This consists, preferably, of two bars 0 and c, of hard rubber, supported on suitable knife-edged bearings c on the shelf D, the bar a being connected at one end to the shelf D and at the other to a pivoted crosslever 0 the other bar a being connected to the cross-lever c at one end and at the other to a rod 0 which projects through the casing A A, and is provided with an adj usting-nut 0 adapted to bear against the bifurcated end of an L-shaped pivoted lever d.
The lever d is provided with suitable trunnions d',preferablyprovided with knife-edges, resting on bearings (31 on casing A A. The lever dis connected at the outer end by a suitable connecting-rod to a balance-arm d resting on a knife-edged bearing d on top of the casing A A, and provided at its outer end with a weight (1''.
Extending downwardly from the outer end of the lever cl is a connection 6, which leads to a pivoted lever e, provided at the outer end with the weight 6 and connected at the inner end by a suitable connection e to the regulat lng device on the lamp B.
The lamp-regulating device which I preferably use consists of an outer sliding tube or shield f, adapted to slide over the wick-tube f and be raised and lowered thereon by a crank-shaft f so as to decrease the amount of flame in a Well-known manner, (see Fig. 4,) this particular construction forming no part of my present invention.
The egg-trays E E are supported on suitable ways 9 between the lower circulating tubes 0 and b and slightly above the same. Immediately below the egg-trays E E are evaporating-pans F, provided with compartments h k of difierent sizes adapted to contain water for evaporation to secure the proper moisture in the atmosphere necessary to the successful incubation. At the ends of the evaporating-pans F are small cold-air ducts 2, which pass through the bottom of the easing A A and furnish fresh air to theinside of said casing.
Near the middle of the top of the casingA A is an outlet-openin g G, which passes through the reservoir 0 into the space above the egg trays E E, and is provided with a suitable damper j to regulate the escaping moisture, and thus regulate the humidity of the atmosphere within the incubator.
The operation of the device thus described is as follows: The reservoir, boiler, and circulating-tubes being filled, as above described, the lamp B is lighted and turned up so as to burn as brightly as possible without smoking. The heat and products of combustion pass into the chamber B and thence through the combustion-fines a to the atmosphere at either side of the outer casing A A, imparting the heat to the Water which surrounds said fiues in the boiler B. As the water becomes heated in the boiler, it rises through the circulatingtubes 0' G to the reservoir 0, the cold water being conducted downward through the tubes 1) b b and enters the bottom of the boiler B. A circulation is thus obtained through the entire system of tubes by which all the water in the reservoir and said tubes is heated to an even temperature, which temperature is imparted to the chamber within the outer casin g A A. When the temperature rises to a point sufficient to expand the rods 0 and c, the expansion thereof is transmitted to the lever d, which, by reason of the weight 6 is drawn down, thus raising the pivoted lever e, which, through the medium of the connection e operates upon the crank-shaft f and raises the Shield f, thus reducing the flame of the lamp and cutting off the heat-supply. A dischargepipe H, provided with a suitable stop-cock H, is provided at the bottom of the boiler, so that the water in the said boiler, circulating-tubes, and reservoir may be drawn oif, as desired, and be replaced by fresh as it becomes necessary.
By the above construction I am enabled to regulate the temperature to a uniform degree, all parts of the incubator being heated alike. The circulating-pipes passing down at the corners and along the sides at the bottom of the incubating-chamber, the cold corners and sides are obviated, the sides, if anything, being slightly warmer than the center.
By use of the pivoted expanding rods 0 and c,I get double the amount of expansion than when a single rod is used, and by use of the levers, connections, and weight, as described, a perfect regulating device is secured of the most delicate and sensitive nature. By having the balance-lever attached to the outer end of the operating-lever cl at one side and the weighted lever e connected thereto at the other side the weight of the said oper ating-lever is counterbalanced and all lost motion is obviated in the regulating mechanism, so that the slightest movement of the expansion bars is transmitted directly to the lamp-regulator. The nut c permits'the device to be adjusted to secure a greater or less degree of heat.
By use of the combustion-fines and the lamp, as described, in connection with the boiler, all products of combustion are carried away from the incubating-chamber and dis charged into the outer atmosphere.
By use of the moisture-pans having the compartments therein, as described, and the escape-flue G the moisture may be regulated to secure the conditions necessary to the successful incubation.
Having thus described my invention, I claim- 1. The combination, with anexpansion rod, of an L'-shaped pivoted operating-lever, a balance-lever connected thereto at one side and a regulating-lever at the other side, and a weight adapted to operate said regulatinglever upon the downward movement of the said operating-lever, and a variable connection between said expansion rod and operating-lever, substantially as specified.
2. The combination, with an expansion rod, of an L-shaped operating-lever provided with laterally-projecting trunnions on which it is adapted to operate, a regulating-lever connected to said operating-lever, a weight to operate said regulating-lever, and a counterbalance connected to said operating-lever on the opposite side from said regulating-lever, substantially as specified.
3. The combination, with an expansion device consisting of two horizontal hard-rubber bars supported on knife-edged bearings and connected, as described, of an L-shaped op crating-lever having the knife-edged bear- In testimony whereof i have hefeiinto setmy hand this 15th day of November, A. D. 10 1888.
