"PATENT OFFICE j WILLIAM HANSON, OF TRENTON J'U1\TC'1IO1\T, NEW JERSEY I INCUBATOR Application filed December 21, 1928. Serial No. 327,656.
This invention relates'to an improved cabinet incubator, and has more specific reference to the internal construction of the incubator, and associated elements which cooperate, in producing a novel heating system The principal novelty is predicated upon' the system of heating including a natural draft circulation, whereby the heat will continue to circulate through the central-shaft and over the top of the partition, and down through the egg compartments, in order that" the temperature of these compartments will be uniform from top to bottom at all times.
A further feature of the invention is based '30 upon the utilization of electric heaters as-' sociated with a register located at the bottom of the central air shaft, as well as the employment of automatic thermostatic switches for regulating the heaters. It follows thatthe outstanding object of the invention is to generally improve upon incubators of this class by providing one which is characterized by a novel arrange ment of parts so cooperating and associated as to better fulfill the requirements of an in vention of this class and to produce stronger and better chicks.
Other features and advantages of the invention will become more readily apparent from the following description and drawings.
In the drawings:
Figure 1 is a vertical sectional view through a cabinet incubator constructed in accordance with the present invention,
Figure 2' is a horizontal sectional view through the same,
Figure 3 is a view in section end eleva-- tion showing the thermostatic switch control Figure at is a longitudinal sectional view through Figure 3, 7
Figure 5 is a wiring diagram.
The enclosure comprises a cabinet of appropriate proportions including a suitable 6b floor 6, together with top, sides, and end walls. Y
The top and end walls arepreferably made of inner and outer sections 7 and 8 spaced apart as shown to provide insulation spaces. Likewise, the sidewalls are composed of spaced elements, the inner elements of which are in the form of removable or hingedly. mounted glass panels or doors 9 and outer solid doors l0. I
This arrangement permits proper access and frequent inspection in a convenient manner. As before indicated I provide a pair of spaced parallel partitions 11 on the interior. These are disposed longitudinally and have their upper and lower edges terminating'in spaced relation from the floor and ceiling re-' spectively. These partitions define the central air shaft 12.
At one end ofthe air shaft is anoutwardly opening entrance door'13 permitting the attendant to enter the structure, if "desired. Suitably supported betweenthe lower portions of the partition is a grating 14 forming a register. Also supported beneath this register are electric heaters generally designated by the reference characters 15.
' In actual practice it has been found advantageousto support a water filled tray or pan 16 on the register to moisten the upwardly circulating heated air. The heaters as well as the registers, are supported in spaced relation above the floor.
The partitions also form a pair of duplicate egg compartments 17 i In this connec-V tion it will be noted that extension floors'18' are formed upon the lower ends of the partition and extend into the compartments 17 to support racks, upon which the receptacles are assembled in tiers. i
tially by the swingable valve plate 21 the 7 same being suspended from theceiling over the central portion of the air shaft 12. This can be swung from its central position to either dotted line position seen in Figure Ito shunt the air column to an opposite side-if desired. 1 V I Formed in the roof or ceiling are a r ven-' tilating openings 22 having automatically operable closures 23. The closure in each 'instance is mounted on a weighted pivotally mounted lever 2 1 whose intermediate portion is connected by an operating link 25 with an expansible thermostat onthe interior of the cabinet.
Associated with the thermostats 2 6 are switch controlling thermostats designated generally by the reference characters 27. The construction of the thermostat is shown in Figures 3 and 4:. It comprises a frame 28 carrying a plurality of double wafer thermo static elements 29.. These have adjustable connections with a slideBO through the medium of an adjustable coupling 31. The slide is mounted in a cross bar'32 on the frame and has a forked end, the arms of which straddle a pivotally mounted contact actuator 33. i l
This actuator carries a relatively movable contact 34 cooperating with a relatively stationary contact 35 on the rigid bracket 36. As shown in the wiring diagram25, the plurality of electric heaters are included in the electric circuits controlled by the. thermostatic switches.
Hence, the circuit is turned off and on automatically according to the temperature;
conditions within the cabinet. In practice, a master control switch 37 maybe provided for throwing the 'heaters out of operation whenever desired.
It is yet to be mentioned that addit onal ventilators 38 may beprovided in the .cabinet, preferably nearthe bottom for introducing cold air at desired intervals.
7 The features to, beem phasiz ed are these. First, the method of circulation of air between the communicating ai fsliafts and egg compartments, is essential to the eflicientioperation of the invention, since this maintains the desired uniform priate incubation. V V
A number of ventilators are provided and these work automatically. The heaters are controlled by thermostatic switches temperature for approbeforestated also operate automatically and these thermostats can be regulated as desired. These and other features and advantages of the invention have doubtless been made apparent from the description and drawings.
Therefore, a more lengthy description is regarded'unnecessary. 7 H V 7 Minor changes: in shape, size, and and rearrangement of parts may be resorted to in actual practice if desired. 7
H vi g hu escr edmy invention, W t I claim asnew is:
1. An incubator cabinet comprising an enclosure provided with longitudinally extending spaced parallel partitions defining a central air circulating'shaft through which air passes upwardly,and a pair of side compartments, said'partitions 'hjavingtheir upper and lower edges spaced respectively from the floor and ceiling of the enclosure, a horizontal register supported between the lower por tions of said partitions, and the heating means located beneath said register, together with a swingably mounted Valvepl'afte suspended from the ceiling and located centrally over said airshaft and adapted to be swung against either partition toshunt'the circulating air in'a desired direction. s
2. Ina cabinetin'cubator'of the class del scribed, an enclosure, a pair of parallel spaced longitudinally extending vertically disposed partitions in said enclosure having their per and lower edgesjterminat ng n spaced relation from the ceiling and floor respectively to'simultaneously form a. central air shaft and an egg compartment on a pair of opposed sides ofthe shaft, horizontal extensions carried at the lower endportion of said partitions and extending into saidcompartments and disposed in spaced relation to the floor,
racks supported on said extensions and located in said compartments, aplurality of recep tacles arranged in tiers on said racks, a'reg-. ister. disposed between the lower end portions of said shaft, heating elements.supp ortedlbe neath said register, a swing ably mounted'cen trally arranged valve plate extending from the ceiling and cooperabl'e with said parti tions for shunting the circulating air in the desired direction, and an entrance doorat one end of said shaft.
