HEATING-TANK FOR INCUBATORS.
Specification of Letters Patent.
Patented Oct. 25, 1910.
Original application led July 3, 1908, Serial No. 441,817. Divided and this application filed January 6, 1909. Serial No. 470,992.
heating incubators as disclosed in my coding application for patent, Serial Num- 'r 441,817, ined July e, 1908.
The purpose of the present invention is to provide a heating tank of such structure lthat it is adapted to fit entirely within the incubator, and having an intermediate chamber or passage-way through the length thereof, and through which the heat passes, thereb obtaining more effective and uniform eating of the water within the tank, thus kee ing the hatching chambers at a more uni orm and effective temperature.
A further purpose of the invention is tol provide the heating-tank with means Whereby the heated air is, in circulating, passed over an exposed film of water, for the purses and with the results hereinafter set orth.
A further purpose of this invention is to provide an automatic heat regulator which, without the use of a thermostat, or other artificial device, but bv means of the air pressure only, will regulate the temperature within the incubator.
With these as the essentials, my invention embodies other advantages that will appear in the course of the following detailed de- Scription, and set forth in the claims.
In the accompan ing drawings illustrating the invention: i ure 1 is a horizontal sectional view of my improved tank shown applied to an incubator; Fig. 2 is a transverse sectional view of the tank shown in Fig. 1, taken on the line a-Z); and Fig. 2a is a similar view taken on the line Lv-w of Fig. 1. Fig. 3 is a horizontal sectional view of the modified form of tank. Fig. 4 is a transverse view of the tank shown in Fig. 3 taken on the line -m; and Fig. 5 is an end elevation of the tank partly shown in section along the line y-y o Fig. 3.
' Referring more in detail to the several views wherein like characters of reference designate corresponding parts in the different figures shown, the tank A comprises a rectangular metallic vessel adapted to be placed substantially wholly within an incubator B. Throughout the length of the tank A there is a passage-way 1 communieating at one end with the heating` means and at the other end with the interior of the incubator. The former of said communications, designated 4, has a downwardly flaring opening whereby the heated air .from
,the lamp G may be gathered and directed into the heating passage-way l. Said passage-way divides the water tank A into a plurality of communicating chambers 2, 6 and 6. The water-chamber 2 is within the lower portion of the tank and extends substantially throughout the surface of the lower wall thereof. The water-chamber 6 is that portion of the tank immediately over the flared opening 4, and projects beyond the outer wall of the incubator B. The chamber 6 is narrower than the chamber 2 .but wider than the passage-way 1 at its fiared end 4, thus forming spaces on each `side of said passage-way which connect said ` chambers 2 and 6 and enable the water 1n the tank to circulate freely therethrough. The Water- chambers 2 and 6` communicate lwith the water-chamber 6 by means of a pipe or inclosed water passage 7, which passage extends throughout the length of the heating chamber 1, for the purpose of giving a greater surface to the action of the heat within said chamber l.
That portion of the tank A within the vwalls of the incubator B is provided with -an upstanding ledge 5 that extends entirely `around the side edges-of the inclosed upper Wall. vprovide a. chamber 3 adapted to receive a `thin` film of water, the function of which The purpose of this provision is to within the tank I have Adevised a means whereby this is readily accompllshed. The means comprising a balanclng bar or rod 9,
. vided an air conducting pipe 16 that communicates with the atmosphere in the operrod 9 carries' at one end a plate 11 adapted to overhang an outlet 12 that delivers the heat into the incubator from the chamber 1, and at its opposite end the rod 9 supports a valve 13 by means of a link 14, said valve seating against the underside of the opening 15. The proper regulation of the p ate 11 and valve 13 is effected by a movable weight 10 upon the rod 9. The valve supporting rod 9 is steadied in its operation by means of u standing guide-wires 8. In normal position the plate 11 and the valve 13 are ada ted to be substantially as that shown in ig. 1, wherein the plate 11 closely overhangs the opening 12 and the inlet 15 is closed. K
When the incubator is in operation the heat from the lamp G, passing through the passage-way 1, enters into the interior of the lncubator by way of the outlet 12, as stated. Now, if for any reason should the heat become excessive the additional outflow acting against the plate 11 would force the same upward, thus permitting the valve 13 to drop; whereupon cold air from the operating room would enter the passage-way 1 by way of the inlet passage-way 15, and reduce the temperature of the air in the passageway 1 until the plate 11 and the valve 13 assumed their normal positions. After the products of combustion have passed through the passage-Way 1 and heated the Water within the inclosed portion of the tank and Within the water-passage 7, the heated air enters the air spaces in the casing of the incubator, makes two circulations, and iinally escapes through the vent 15 on top of the incubator into the operating room, in the manner described in my patent for incubators, dated June 29, 1909, No. 926,434. To moisten or condition this heated air before it is diffused in the incubator operating room, I subject the same to the action of the exposed film of water 5. Then this moistened air, passing into the o erating room, returns by Way of the venti ator 16 into the egg chamber. The purpose of this construction is to keep the air in the room in which the incubator is bein operated as fresh as the air out of doors. lach egg has enough natural moisture in itself to hatch well if it does not come in contact with dry air, which is certain to take from the egg some of its natural supply of moisture. Another advantage of this construction is that the bottom of my heating tank is of the same temperature over its entire area, owing to the opposite directions of the returning water and the outgoing air.
To the underside of the tank there is proating room, and which is provided with perforations 17, through which said air is conducted into the several hatching chambers,
In the modified form of tank shown in Fig. 3, the construction is substantially that shown in Fig. 1, excepting that instead of having the exposed film of water on the upr wall .of the tank I have means for holding the same within the assage-way 1, which means comprises a le ge or plate 23, welded or otherwlse secured to the bottom of said passage-way adjacent to the opening 4; and there 1s a further advantage that instead of having an inclosed passage-way for conducting the water through the length of the chamber 1 I form a separate wall, which divides the tank into an upper and lower water-chamber, designated 21 and 22 respectively. The inclosed water-chambers are adapted to be filled by means of the pipe 19, and the chamber for holding the eX osed film of water by the pipe 20, both o said ipes communicating with the outside of the incubator. In this type of structure the heat, in passing through the passage-way 1, is subjected to the exposed water and is thus moistened or conditioned before entering the interior of the incubator chamber.
If desired, the film of exposed water may be carried u on the top of the tank, as illustrated in 1g. 1, without departing from the spirit of my invention.
In both of the structures shown, the operation of thus treating the water is equally effective, but by reason of the simplicity of structure of the tank in the former instance I prefer and have shown that kind. There may, of course, be other types of tanks for effecting this same result, and I therefore do not wish to be understood to limit myself to the precise details disclosed, but rather reserve, instead, the right to make such changes as will better adapt the invention to its purposes, and in doing so limit myself only to the prior art to which this invention pertains.
I claim:
1. A hot Water heater comprising a tank provided with a horizontal passageway therethrough having a downwardly turned mouth at one end opening on the under side to receive heated air and an opening on its upper side near each end, said passageway being as Wide as the tank for the greater part of its length, but narrower than said tank at the mouth end, and automatic valves controlling said upward openings.
2. A hot water heater comprising a tank provided with a horizontal passageway therethrough having a downwardly turned mouth at one end openin on the under side to receive heated air, sai passageway being as wide as the tank for the greater part of its length, but narrower than said tank at its mouth end to provide Water communication between the front end of said tank and the portion below the heating passageway, and a water circulating tube extending through said heating passageway connecting the front to the rear of said tank.
3. A hot Water heater comprising a horizontal tank divided by a horizontal diaphragm into an upper and lower section, the upper section serving as a passage for hot air and opening at the bottom of the tank to receive heated air, the lower portion of said tank adapted to hold Water' and having a forward and a rear Water section in communication therewith, and a circulating tube extending through the hot air section to connect the front and rear ends of the Water tank to eause water to circulate therein.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
