Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed February 7.1907. Serial No. 356.186,

To all whom it may concern Be it known that l, SYLYAN FRANK BIHN, a CiliZCll of the United States, residing at Petalunia, in the county of Sonoma and State of California, have invented certain new and useful linprovements in lncnbat ors: and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperiains to make and use the same.

This invention relates to imprtwements in incubators.

The object of the invention is to provide a continuous incubator having a plurality of compartments heated from the same source whereby the daily care, adjusting and clean- .ing'o'f many lamps or heaters is dispensed with and the time and. labor required for rttnnii'ig t'lie'incubatoi' reduced to a minimum. 1

Another object is to provide means for regulating the temperature in the various eon'ipartmen1s,-intlependeirlv of each other to provide for the differences in temperature of the several compartmens caused b v the variations in the heat produced by the embryo in its various si ages of development.

Another object. is to provide improved means for turning the eggs in bulk without injuring them and wizhont removing them from the incubator.

Still another object is to provide means for properly cooling the eggs during the process of incubation without removing them from the incubator and thereby avoiding uneven cooling of the eggs, whereby some are chilled, while others are not cooled stillicicntly when lit are removed from the ineubator to cool them.

Figure l of the accompanying drawings represents a perspective view of this iniproved continuous incubator with the lid of one compartment partly raised and with the side door open to show the interior thereof: Fig. 2 represents a perspective view of the portable tray holder for the incubator; Fig. 3 represents a perspective view of a corrugated tray for holding the eggs during the process of incubation; Fig. 4 represents a side View of the incubator showing the heater at one end and the heat regulat ing device on the top thereof; Fig. 5 represents a side elevation partly in perspective of the hot water device, the expansion cup and the heater detached and in position ready to h connected with the incubator; Fig. 6 represent a. top plan view of the incubator showing the heater at one end and the expansion cup at. the other and with the top removed; Figs. 7 and N represent. side elevations of an insulator for the hot water device at the up- 'per part. of the incubator being shown open in Fig. 7 and closed in Fig. s: l ig'. H represents a perspective view of one of the instilator or enveloper tnemhers detached: l ig. It) represents a perspective view of one of the incubator compartments showing the operative relations of the different heating and regulating devices.

lit the embodiment of the invention herein illustrated, a continuous incubator l is shown composed of a pluralit of individual compartments as 2. preferably disposed in longitudinal alinement to provide for the arrangement therein of a hot water h ating de'- vice in the simplest manner; they may how ever be arranged iii any other suitable or tle sired position. i

i\ll of the compartments 2 are supplied \\l1lt heat from a single plant or heater here inafier described. 'lhe compartments 2 being all alike one only will he described. llach of these compartments 2 constitutes an incubator chamber and is provided with a hinged top It which tightly tits on said chamber when closed to prevent the escape of heat therefrom and adapted to be opened to admit fresh air to the eggs to cool them during the period of incubation without necessitating their removal from the chamber wherebv some are liable to be chilled and others not cooled nllicientlv owing tt. the fact that the eggs have heat of their own and lying close together will heat by contat't and when removed from the incubating chamber into a low outside temperature, the eggs on the outside of the tra will -eliill while those in the center will not be stillieienilv cool, causing the hatches to vary some days. 7

With this improved incubator, when it is desired to cool the eggs, the lid 2% is propped open at the desired height. causing a slow even cooling of the eggs and producing even hatches and a high percentage of healthy strong ehielts. Each lid 2; has a ventilating aperture l therein closed by a slide 5 which may be opened an v desired w-idt h to properly ventilate the chamher giving a direct means for the carbonic-acid to escape without creating a draft. Carbonic-acid gas which i is thrown off by the eggs during the process vided with a egg trays.

of incubation is present in larger quantities atthe top of the egg chamber as when heated carbonic-acid gas is lighter than air, while when cold it is heavier. v

Each chamber or compartment 2 is reortable tray holder 6 w ich consists of a fiame corresponding in shape to the shape of the chamber andit rests and slides on the bottom of the com artnien't. It' is preferably lar e enough "to old four This he der 6 is preferably provlded with flanges 8 for the trays to rest and slide upon and it obviates the necessity of using a table to set the trays on as with this tray holder, it is only necessary for the operator to draw the holder 6 containing the filled trays hereinafter described artly from the chamber 2 with its outer enr resting on the knees of. the operator and the eggs may thenbe turned in bulk as hereinafter described. This tray'holder is preferably provided with two hand-holds as 9 for withdrawing it. The egg trays 10 are preferably made as shown in Fig. 3 with parallel corrugated rooves as 11 so'arranged that the e gs lai in the corrugated grooves will slight y overlap 'each other and the eggs are so placed in each groove that those in one groove will be a little past those in the other groove and project up out of thegroove suflicientlfy hlgh so that'the largest circumference 0 one egg in th1s groove will fit in the cavity between the two eggs in the ad acent grooves, thus if the eggs in the groove are laid lengthwise with the large ends one way and the small ends the other, the o erator by placing his arm across the tray irectly againstthe small ends of the eggsto hold them firmly together, may then raise the other end of the tray up rather quickly, which will cause the upper layer of eggs to commence to turn, then by giving away gently at the lower or smaller end of the eggs they will all turn over smoothly and at the end of the'incubation period ive as a result a less percentageof loss {ha n if they had been turned by hand in the old Way. The incubator chambers 2 are each prov'ided'with a front or side door 12 which opens to permit the trayholder to be moved in and out.

All of the compartments 2 are heated by a single heater lf) which preferably consists of'an outside circular shell or jacket 20 which has a circular top or cap 21 fitting tightly inside thereof, so that the heater may be closed when needed. This heater has a radiating ilue BU projecting through the top thereof. In the outside jacket. 20 near its top and on a level with the hot Water space and directly back of radiating flue 30 is a one inch hole 32 for a solder nlpple 33 which is connected to inside shell of the heater and passes through the hole with the in out-side acket 20 and has on its outer end screw threads for a union to be screwed on so that the hot water pipe 48 may be screwed into the other end or the union, thus connecting the hot water space with the supply pipe 50. Near the bottom of the heater in outside shell or jacket 20 on each side is'a one inch hole, for nipples which have screw threads on the outer ends just outside of jacket 20 to receive unions screwed thereon, and the short pieces of pipe fronr elbows 42 and 43 may be screwed into the other end of the two unions on each side of the heater. These two short pieces of pipe extend far enough out from each side of heater and are connect the lower end of the hot water reservoir in the heater with the return pipes 46 and 477 The outside jacket 20 extends below elbows .42 and 43 sufiiciently to leave a one inch space for heat. Thus if the'heater be connected to hot water pipes '46, 47, and 48 as shown in Fig. 5, the receiving cup 49 at upper end of perpendicular pipe 50 be filled with water the water willdeseend and make turns at elbow 51, pass lnto end pipes 52; hereit is divided into pipes 46,

47, and 48 passing through pipes 46 and 47 at elbows 53 and 54 and entering the heater through the short pipe beyond elbows 42 and 43 and also through flow pipe 48 into the reservoir in the heater at its top, thus filling up the hot water space inside the heater. A lamp (not shown) is disposed in the radiating fine 30 and the heat therefrom will rise straight up through the radiating 30 and escape therefrom, if the damper 34 on top of the radiating flue 30 be open (see Fig. 4). If the damper be closed, the heat side of the radiating flue 30 and fill up the hot air space around the radiating fine 30, thus heating all hot air surface on the inside thereof.

In Fig. 4 is represented a side view of a continuous incubator showing the regulating device for regulatiiig the heat from the gasolene-hcater. It shows the damper 34 placed directly over the opening in the upper end of radiating llue 30. This damper is connected to the curved end of a lever 65. This lever- 65 has at its other end an adjustable sliding weight or knob (56 and the lever works on a pin 67 in the bracket 6%, which is fastened to the top of the incubator in the firstin the ii'mubator raises it from the top ofthe radiating llue h 0. Near the fulcrum on. the side next to the heater the lever 65 has a small hole 69 with screw threads cut in it fumes will pass out the holes in the connectedwith the pipes 44 and 45 which half o to receive the set screw 70 which is screwed through the lever and rests in a little cup 71 on the upper end of a )erpendicular rod 72 which extends down t rough a hole in the top of the incubator, and has an expander 73 on its lower end. The expander 73 is preferably composed of three or more waverdisks arranged one above the other in close proximity and is preferably made of spring copper. This expander 73 is fastened to the bottom of a bracket 74 which has side braces extending up on each 'side of the expander which are fastened to the under side of the top of the incubator casing. lf the waverdisks in the expander 73 be filled with some volatile liquid or gases which when heated will expand, and PUSll up on rod 72 causing its cup 71 to bear against the lower end of the set screw in lever 65, this lever 65 will lift the damper 3% from the'opening in the top of radiating flue 30 and allow the heat that is not needed to escape. The expander 73 in its bracket is preferably arranged just above the eggs in. the corrugated tray inside the incubator so that the added heat from the eggs when they are in the course of incubation will also have its effect on the expander 73 to open the damper.

An insulating device for arch of the hot water pipes 46, 47 and 48 is shown in Fig. 8 and consists of two flat pieces or dates 75 and of non-conducting materiaf of snlfi-- cicnt width to span the "ripe to which it is ap plied and each provided with flanges 76 and 77 and SJ and 82, along each side for about one-half the length thereof. Each plate with its flanges is made exactly like the other, the plate 75 lesigned to be placed on the under side of a hot water pipe with its flanges turned upward and the plate 80 to be placed on top at a hot waterpipe with its flanges on thereverse end and turned down,

-so that when they are closed together the part of the hot water pipe between them will be completely enveloped. The plates 75 and 80 are hinged to the end walls of the compartment n which they are placed at 78 and 83 respectively. There is a pair of these envelopers provided for each of the hot water pipes in each compartment of the continuous incubator. The three envelopers as 75 are connected together at each end by cross iieces, as SH), thus forming the lower fthe insulator into a frame of sufficient length to reach from pne end of a compartment along pipes 46, a7 and 48 to the other end with all flanges turned up at right end; three envelopers as 80 are formed in a frame to be. placed on top of hot water pipes 46, 47 and 48 with. all their flanges turned down at right hand end of conlpa'rtment. The top enveloper frame is hinged to the left hand end of the wall of the compartment, or end of incubalor, and the right hand end of envel- Rod 102 with its pin at each end fits in a hole in the brackets that are -fastened at the 11ndthe center of the tray-holder as shown in Fig. 1 as it will be placed across the width of the tray holder in each compartment of the continuous incubator. The ex )ander lever 103 is hinged to the right hanrf end wall of the compartment of the incubator between bars Hit) and passes a little pclow rod 102 a short distance and is connected by a perpendicular rod 104 at its left hand end to a cross piece just to the left of the flanges on top of enveloper St) and has a set screw on the up- )e'r end of rod 104 for raising or lowering the left hand end of the expander lever 103 so that the operator may regulate the heat from the hot water pipes 46, 47 and 48.

The expander lever 10.; has fastened near its hinged end an expander 105. This-expander 105 is composed of three or more wafer disks one above the other disposed in close proximity and preferably made of spring copper and thus can bo filled with some volatile liquid or gases which when heated will expand and push upward. Directly above this expander is a rod'ltlfi which is fastened at its upper end to underside of the cross piece of enveloper frame 75 and extends down directly over the expander 105 with a flat base at its lower end spaced at short distance from the top of the expander 105. Thus if t he expander 105 be filled wit h some volatile liquid or gases which will expand or contract according to the heat of the incubator, and this heat is of the required amount it will cause expander ,1 ()5 to expand against the base on the lower end of the base rod 106 and thus push up against the under side of the cross piece that is across the right hand underside of enveloper frame 75. And the flanges on the left end of envelopor frame 75 being pushed up on each side of hot water pipes 46, 47 and LS and up against the underside of the flat piece of left end of enveloper frame 80, thus mvcloping this part of hot water pipes elfi, i7 and -18. hen expander 105 has expanded and pushed up against the underside of the flat piece on the right hand end of enveloper frame 75, thus causing the left hand end of enveloper frame 7:") to pull up the left hand end ofbars 100 and the right hand end of bars I00 to pull down the right hand end of enveloper frame 80 lo the flat part of the left hand end of enveloper 75 thereby finishing the closing process and en- 1 veloping of the hot water pipes lo, 47 and die inside walls of the incubator, and. above one and one-half feet apart to a rod 102.

&

Therefore the radiating heat of the hot water pipes 46, 47 and 48 is retained Within the en velopers as 75 and 80 in this compartment of the continuous incubator until the temperature in this compartment has sufliciently lowered, causing the expander to contract, and lowering down from the base on the lower end of base'rod 106 relieving the pres sure from the same, thereby causin enveloper frame 75 which is slightly heavier than the enveloper frame 80 to drop down and away from the hot water pipes. Thus when enveloper frame 75' drops down it pushes down on the left hand end of bars 100 caus ing right hand end of these bars 100 to push up the right hand end of enveloper frame 80 thereby uncovering the hot water pipes and letting out into this compartment all theretained radiating heat that was held in the revious closing process. Thus the heat om the hot water pipes running through the different compartments of the continuous incubator can be regulated for each compartment by the set screw on the upper end of perpendicular rod 104 by the operator reaching down through the slide opening in the lid. Thus it each compartment of the continuous incubator be provided with this automatic insulator, and the temperature being different in each compartment owing to the different stages of eggs in incubation, these different temperatures in the different compartments of this continuous incubator may all be equally adjusted by the set screw under the slide opening in: the lid or cover tor each compartment of this continuous incubator when said lid or cover is closed down.
