A further object of my invention is to provide an eficient portable incubator for infants which is simple to operate, can be economically and cheaply manufactured, is sturdy in construction, and is reliable in use.
Another object of my invention is to provide a practical and efficient incubator for infants which can be constructed of relatively light sheet metal and wherein the walls thereof have a reflective surface, providing relatively good insulative properties.
Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by Way of illustration, show preferred embodiments of the present invention and the principles thereof and what I now consider to be the best mode in which I have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

Fig. 1l is a schematic diagram of the wiring for the heating system used in a modified form of my invention.
For purposes of illustration an incubator 2U, which embodies the principles of my invention, is shown in the accompanying drawings, and which incubator 20 is formed substantially in the shape of a rectangular box or casing having a bottom wall 22, a front wall 24, a rear wall 26, end walls 28 and 30, two compound doors 32 and 33 and a longitudinally extending door 35, the three doors `32, 33 and 35 comprising the main portion of the top wall unit of the incubator 28. Runners 36 and 31 are attached to the bottom wall 22 by suitable means such as bolts 38 and act as supports for the incubator 28.
In general, the incubator 20 comprises an incubator chamber 40, into which an infant may be placed and from which an infant may be removed through the top of the incubator 20 when the doors 32 and 33 are open; a heater chamber 4|, disposed below the incubator chamber 40 and separated therefrom by a baby-supporting panel 43; and an auxiliary chamber 44 extending longitudinally of the incubator 28 and disposed laterally from the incubator chamber 40 and the heater chamber 4I, and separated therefrom by a vertical, longitudinally extending partition 45.
The front edge portion of the end walls 28 and 38 are bent substantially transversely to form flanges 41 and 48, respectively, which are secured to the respective adjacent end edge portions of the front Wall 24 by suitable means such as rivets 49. Similar rear flanges 58 and 5l are formed at the rear edge portion'of the end walls 28 and 29, respectively, and are attached to the respective end edge portions of the rear wall 26 by suitable means such as rivets 52.
Likewise, as is best shown in Fig. 4, the lower edge portion of the end walls 28 and 30 are bent transversely to form flanges 54 and 55 which are attached to the respective adjacent edge portions of the bottom wall 22 by suitable means such as rivets 56.
The front wall 24, the bottom wall 22 and the rear wall 25 are formed of one piece of material and may be formed by a bending operation in a manner well known to the art.
In the manufacture of my incubator, I prefer to make the front wall 24, the bottom wall 22, the rear wall 26, the end walls 28 and 30, the doors 32, 33 and 35, the panel 43 and the partition 45 of my incubator 20 from reflective, relatively light sheet metal such as, for example, sheet aluminum having a thickness of eighty-thousandths of an inch, although other suitable materials, and other thicknesses may be used without departing from the purview of my invention. Forming the incubator 20 from aluminum, as I prefer to do, has the advantage of providing a structure which is light in weight and, also, one which is reectively insulated to a considerable extent.
The baby-supporting panel 43 comprises a top wall 58 and substantially vertically disposed side walls or supporting legs 59 and '68 which depend from the longitudinal edge portion thereof. As is best seen in Fig. 5, when the panel 43 is in position of use within the incubator chamber 40, the supporting legs 59 and 68 rest on the bottom wall 22 of the incubator 20 and support the top wall 58 of the panel 43 in spaced relation thereto. As is best seen in Fig. 8, a wire handle 6| is pivotally attached to the upper surface of the supporting panel 43 by a bracket 62 and can be easily grasped by the operator to remove the panel 43 from the incubator chamber 40 when it is desired to rei'fmovefthel sa-me cleaning'fthe finteriora-ofsthe lsincubatoriimlgor for anyfother" purpose. top 'wall 58 of the infant-supporting.;panelc4 has eperforationsr63 formed therein for purposeswhich 'awill `be presently explained.

As is best seen in Figs. l, 4 and 8, a suitable electric socket |46 which is adapted to receive the lprongs of a connecting plug on the end of an electriccord such as the cord |4511, shown in Fig. 8, is"`mounted in the lower end portion of the end wall 23 of the incubator 2B adjacent to one end ofthe auxiliary chamber le4, and is suitably electrically connected/inparallel, to sockets.` |48 and l'| 43 in which may be mounted light bulbs |`5| Iand |52, respectively. The end portions ofv the VVsockets "|48 and |59 into which the lightbulbs. "I 5I and |52 may be screwed extend through suit- 7 the respective end walls 2s and 30 en suitame flanges |59 and |60, respectively, and are adapted to control the parallel circuits to the bulbs |5| and |52, respectively.
As is best s;en in Fig. 8 and the wiring diagram shown in Fig. 10, electricity is supplied to the bulb |5I from the plug |46 through a main power line |62, a branch line |63, switch |56, a branch line |64, the socket |48, a branch line |65, and a main power line |66, and electricity is likewise supplied to the bulb |52 from the plug |46 through the main power line |62, a branch line |68, the switch |51, a branch line |69, the socket |49, a branch line |10 and the main power line |66. The lines |63 and |64 leading from the power line |62 to the switch |56, and from the switch |56 to the socket |48, respectively, extend upwardly through an opening |12 formed in the top wall 61 of the auxiliary panel 65 to the switch |56 which is mounted in the upper end portion of the auxiliary chamber 44.I Likewise the lines |68 and |69 which connect the power line |66 to the switch |51, and the switch |51 to the socket |49, respectively, extend upwardly through an opening |14 formed in the top wall 61 of the supporting panel 65 to the switch |51 which is also mounted in the upper portion of the auxiliary chamber 44.
As is best seen in Figs. 8 and 9, insulating members |16 having suitable sheet metal covers |18 and liners |19 are attached to the lower surface of the upper wall 58 of the infant-supporting panel 43 by suitable means such as rivets |8| directly above the light bulbs |5| and |52, respectively. The insulating liners |19 of the insulating panels |16 may be made of any suitable material such as, for example, asbestos. The insulatng panels |16 act both as heat shields and light reflectors so that extremely warm hot spots are not formed on the portions of the infant-supporting panel 43 positioned directly above the light bulbs |5| and |52, respectively, and also so that light does not shine upwardly directly from the light bulbs |5| and |52 through openings 63 formed in the supporting panel 43.
As is best seen in Figs. 3 and 8, an opening |83 is formed in the central lower end portion of the front wall 24 through which light bulbs |5| and |52 may be placed in, and removed from, the sockets |48 and |49, respectively, when it is undesirable to open the doors 32 and 33 and remove the supporting panel 43 during certain times such as, for example, when an infant is in position within the incubator chamber 40. A removable panel |85 is normally positioned over the opening |83 and secured to the front wall 24 by suitable bolts |81, the panel |85 being removable from the front wall 24 by unscrewing the bolts |81. I prefer to make the opening |83 as small as practicable so that ifa light bulb burns out when an infant is in the incubator chamber 40 and it is necessary to remove and replace the burned out bulb, uncovering the opening 83 by removing the panel |05 will provide as small an opening as possible so that the infant will not be subjected to unnecessary drafts. Therefore in the preferred form of my novel incubator 20 the opening |83 is just large enough to readily pass light bulbs such as the light bulbs |5| and |52 therethrough and this, in some instances, will mean that a normal sized adult hand cannot be extended through the opening |83 to remove and replace light bulbs from the sockets |48 and |49. However, mechanical hands or mechanical fingers, such as the type which are used to Aremove and replace light bulbs from certain inaccessible light fixtures', and which are well known to the art, may be used for this purpose.l
In many instances, new-born infants, and especially those prematurely born, are so frail and weak that it is impossible or difficult for them to breathe a sufficient amount of air to sustain life, and in those instances it is often necessary to supply substantially pure breathing-oxygen to the infant. In the use of my incubator', the supplying of breathing-oxygen to an infant may be easily accomplished by placing an oxygen bottle, such as the oxygen bottle |90, Figs. 2 and 3, in reclining position upon the top of the auxiliary supporting panel 65 within the auxiliary chamber 44, and feeding oxygen from the Vbottle in controlled amounts through suitable mechanism such as a valve |9I, a regulator |92 and a tube |93 into the incubator chamber 40. Suitable pressure gauges |95 and |96 may be provided to indicate both the pressure of the oxygen in the bottle |90 and the pressure of the oxygen as it is fed to the incubator chamber 46. As is best seen in Figs. l and 2, the tube |93 through which the oxygen is supplied from the regulator |92 to the incubator chamber 49 extends through an opening |98 in the longitudinal partition 45 which separates the incubator chamber 40 from the auxiliary chamber 44.
It will be noted that when an infant is in position in the incubator chamber 40 and it is found necessary to operate or change the setting of the oxygen valve |9| or to turn on or turn off the switches |56 or |51, this may be accomplished by opening the door 35 to the auxiliary chamber 44, which operation does not open the incubator chamber 40 and therefore precludes the possibility of thereby subjecting the infant therein to objectionable or dangerous drafts.
Two handles 200 and 20| are attached to the outer surface of the end walls 23 and 30, respectively, by suitable means such as screws 203, and by grasping a handle in each hand one man can easily carry my novel incubator 20 even though an infant is in position within the incubator chamber 40 and a full supply of oxygenjis positioned within the auxiliary chamber 44. In the normal operation of my novel incubator, a suitable pad is placed on the top wall 58 of the infant-supporting panel 43 and the incubator is then pre-heated by connecting the electric plug receptacle |46 to suitable electric power and operating one or more of the bulbs |5| and 52 under the control of the switches |56 and |51, respectively. The doors 32 and 33 are then opened wide and the infant placed on the pad on the supporting panel 43 and the doors 32 and 33 are then closed the desired amount. To protect the infant against objectionable drafts, and also to assist in maintaining the proper temperatures within the incubator chamber 40, it normally will be desired, and especially in chilly or cold weather, to keep the doors 32 and 33 fully closed after the infant has been placed on the panel 43. However, during certain times, and especially during warm weather, it may be desirable to have the doors 32 partly open and this may be easily accomplished by either partly or fully opening the door panels |06 and ||2 as desired. Whether to have the doors fully closed or partially open will depend on the circumstances of each individual case and therefore it will be necessary for the operator of the incubator in each case to determine the procedure to be followed.
It will be noted that if a relatively light pad such fas., for" example` `a blanket, is used :on- .the-1. panel 13,so as to fully coverthe-top wall 58'there---y ofporfif4 a hea-vierpad is -placedon-the top-wall 58 of. 1the-panelw=43 Fin suchf-.a manner-'that all, or .apart of;'the openings "63 nearestf the periph* f 5 eral edge of thetopfwall 58'of the supporting panel 43 are left uncovered, lightfrom'thefbulbs e I5| -and |52 -willbe difusedupwardlythrough.F the lighter, pad, or; ifa a'4 heavier" pad ist-used;
