UNITED STATES MOSES E. LEWIS, 0F TOLAR, ,TEXAS.

INCUBATOR.

Application filed August 24, 1923. Serial No. 659,218

To all whom it may concern:

Be it known that I, Mosns E. Lewis, a citizen of the United States, residing at Tolar, in the county of Hood and State'of Texas, have invented new and useful Improvements in Incubators, of which the following is aspecification.

This invention relates to incubators and contemplates a strong and simple construction, with a novel construction of means for regulating the temperature of the incubator.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indiparts in the several views, and wherein:

Figure 1 is a front elevation of the incubator.

Figure 2 is a view taken at a right angle to Figure 1 with the door open showing the tray partly removed.

Figure 3 is a top plan View.

Figure 4 is a sectional View taken on the line 4-4 of Figure 2, showing the normal position of the heat regulator.

Figure 5 is a similar view showing the active position thereof.

Figure 6 is a detail view of the radiator.

Referring to the drawings in detail, 10 indicates the body of the incubator which of course can be constructed from any suitable material, and vary in size and configuration without departing from the spirit of the invention. The body is preferably of rectangular formation in plan, and the bottom is provided with a plurality of air inlet openings 11. One side of the body is provided with a door opening, normally closed by a hinged door 12, and this of course permits access to be had to the incubator, and also allows the tray 13 to be conveniently inserted and removed from the body portion when desired. The door of course is held closed by any suitable means and is further provided with a sight opening 14, although all the walls may be provided with such openings if desired which openings are covered by suitable transparent material. The'tray slides upon and is supported by cleats which are secured to the opposite walls of the body 10 thereby spaclng the tray a slightdistance from the bottom of the incubator.

The incubator is heated by a heater 18 which may be of any suitable construction, the heater being preferably in the form of a lamp as shown which is supported upon a platform or base 19 secured to one end of a bracket 20 which in turn is suspended from one side wall of the incubator. Arranged immediately above this heater and supported by the adjacent side wall of the incubator is a casing 21 having an opening in the bottom thereof, indicated at 22 to receive the heat from the heater as is obvious. This casing 21 is slotted as at 23 and this slot coincides with a slot 24 formed in the adjacent side wall ofthe incubator to receive the neck portion 25 0f a radiator 26. This radiator is of a size and shape to snugly accommodate itself within the body of the incubator and is supported immediately above the tray abovementioned. The neck portion 25 communicates with a water container 27 which container surrounds a chirn- I ney 28 through which the products of combustion pass as they enter the opening 22 in the bottom of the container 21. Of course the water container 27 is connected with the chimney 28, so that the chimney and radiator may be removed as a unit from the incubator at any time desired, and for any purpose whatsoever. The top of this water container 27 is provided with a water inlet 29, so that the container and radiator can be supplied with the necessary amount of water, which of course radiates heat and maintains the incubator at a proper temperature.

For the purpose of regulating the temperopening being normally closed by a damper.

34 which reposes upon the top of the incubator but carried by one end of a lever 32 pivoted at a point between its ends on a suit able bracket 33, which in turn is attached to the top of the incubator. The other end of this lever 32 is bifurcated as at 35 to receive a rod 36 which passes upwardly through an opening in the top of the incubator for a purpose to be hereinafter described. Arranged in end to end relation with the lever 32 is another longer lever 37, the latterbeing pivoted as at 38 on a suit ablebracket 39 also secured to the top of the incubator, Ihe adjacent ends of these levers 3.2 and 37 respeaively overlap, so that the former is actuated by the latter when, it

is tilted upon its pivot in one direction.

threaded at its upper end to: receive a nae 42 which: ottourse repose's upon the upper surface oi the level: This ro'dv36 depends from the cover intotheihcubator and. isterminally connected with the adjacent. end of a weighted lever 44:," the latter being fulcrumed between its ends a-sat 5 upon the bifiircated: extremity of a substantially [L- shaped. bracket arm 46 which: is also. secured to the underside of theoover of the incubator.

Also supported on. the Leshaped bracket arm.

4:6 is a thermostat 47. which is riveted or otherwise secured as indicated at. 48.. The inner: endi'or the nee end of the lever'44 is disposed directly in the path of: expansion of the: thermostat-so; that upon overheating;

of the incubator the lever 44' will be rocked: and! through the instrumentality of the parts- 32 and 37 the 'dam per s 34:: and; 41 will be elevated as indicated in Figure 5-. This will permit the escape of heat through the open ing 30 and chimney 28.

WVhile it is believed that from the foregoing 'descrip'tioi'i, the nature and advantages oi? the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed,

Having thus described "the invention, I claim:
