With the above and other objects in view, In the present preferred form of the invention, which will appear as the description proceeds, the support for the infant comprises a drawer 10 the invention resides in the novel construction, consisting of a frame 11, the side rails of which 90 combination. and arrangement of parts, subare notched to slide upon the ways 12 secured stantially as hereinafter described and more parto the interior faces of the side walls 2. Positicularly deflned by the appended claims, it betioned within the frame 10, and pivotally conlng understood that such changes in the precise nected to the side rails by means of a transverse 40 embodiment of the herein disclosed invention rod 13 is a tiltable table 14 comprising a top 15 95 may be made as come Iwithin the scope of the secured to the spaced longitudinal sills 16, which claims. in turn are mounted upon the rod 13. Cross In the accompanying drawings is illustrated members 17, connected to the lower edges of the one complete example of the physical embodiside rails adjacent their ends, serve to limit the ment of the present invention constructed actilting action of the table 14, which is rotatably 100 cording to the best mode so far devised for the adjusted to the desired angle by means of a practical application of the principles thereof. threaded rod 18 projecting through the front 19 In the drawings: of the drawer frame, and which is provided with Figure 1 is a longitudinal Section through an -a hand-wheel 2o for manipulation. thereof.

Obviously, as the rod 18 is rotated, the away and in section to more clearly illustrate clevis 21 is run in or out, causing the table to structural features. rotate upon the transverse bar 13, thus shifting 110 the table to raise or lower the head oi the in faut.
inasmuch as some clearance must be provided in the opening formed in the doors 7, the same are provided with hooks 2e, irorn which a cloth 25, indicated in dotted lines, is supported to sur=- round the infants neel: and retain the heat within the compartment 9. 5
, For heating the compartment 9, various forms of electric elements may be employed, such as incandescent bulbs 2d, which are secured to the interior of the top fi, and connected with a therf, mostatic control 27 secured to the rear wall 3, it being understood that the thermostat may he adjusted to operate at predetermined temperatures. A conventional socket 28 secured tok the outer face oi the rear wall 3 is connected to the thermostat, and receives a conventional cord plus 2e. through which current is supplied to the lights 26. For convenience a thermometer 29 is sup- I ported upon the rear wall 3, and where it is desired to humidity the air circulated through the openings 5o formed in the rear wall 3, and through the iront panel 5, when the glass slides are open, a humidifier 3i, in which a wick or felt pad 32 is positioned, is supported upon the interior ci one ci the side walls 2.
From the foregoing explanation, considered in connection with the accompanying drawings, it will be readily seen that an extremely simple and inexpensive incubator lia-s been provided, which can ce readily transported from place to place, and can lie easily controlled tofprovide any desired condition within the heating compartnient 9 containing the infants icody.
it will further be noted that insertion or ren inoval oi the infant is materially facilitated by means ci tlieslidina drawer, and the swinging doors "l, inasmuch as the drawer, when extended,
allows the infant to he properly arranged and positioned thereon outside oi tne cabinet, which renders the operation most convenient, after which it is merely necessary to slide the drawer inwardly and close the door leaving the body positioned within the heating chamber, with tlie head projected therefrom and positioned in the open end of the cabinet, where it may he fed, or otherwise observed without moving or disturbine the todo, or opening tile cabinet. Fur

thermore, without disturbing the infant, or opening the cabinet, the angle of its 'body may he varied as desired iov pulatins the hand-f wheel 2i). f
in some instances where it may bedesired to provide a more inexpensive structure, although not as convenient or desirable, the sliding drawer i0 may be eliminated, and a permanent bottoni 33 may be provided for the cabinet, such as shown in the modification of the invention illustrated in Figure fi. Such bottom may he either rigid or adjusta'ile, and, outside oi the question ci convenience, produces the saine ultimate results.
