Appli-cation filed February 16, 1917. Serial No. 149,006. v
To all whom it may concern:
Be it known that I, FRANK N. BLAGEN, a citiaen of the United States, residing at Hoquiam, in the county of Grays Harbor and the State 0f lvashington, have invented a new and useful Electric Incubator, of which the following is the specification.
The object of my invention is to provide an electricincubator having an improved combination and arrangement of parts whereby inconvenient and frequent removal of the mercury or cleaning is not required. It is a further object of my invention to provide an improved arrangement of the resistance wires.
I attain the object of my invention by the accompanying drawings, in which- A 4 Figure l is a longitudinal vertical section through an incubator to which the invention is applied; Fig. 2 is vention, partly in diagram; and Fig. 3 is a top plan.
Like characters of reference designate like Several views.
Referring to the accompanying drawings, I provide an incubator. casing having in its upper portion insulating strips L extending `longitudinally of the incubator at' opposite vide a novel heating element consisting of rides and mounted on cross strips M. I'proresistance wire N connected back and forth ,in U-shaped arrangement continuously from one end of the incubator to the other, wires being spaced not more than four inches apart, as illustrated. By this improved arrangement of the heating element all parts of the egg tray beneath can be heated within one-tenth of t vide a fuse cut-out O to which wires Q and R are connected -from the service mains. Thence wire R is connected directly tothe heating element Wire Q is connected through the secondary circuit ofthe electrical relay T to the heating element N.
The lines from the battery or low voltage circuit U connect as follows: One wire connects directly to the. primary terminal Grof thus closing the battery circuit the relay T and the other wire connects withillustrated in Fig. 2.,
A Balancelever C has its opposite end arranged the balance lever C, as
mercury cup F, which terminal H, through the C is o eratively connected by with a suitable to touch the mercury in is fastened to primary relay relay.4 Lever means of a rod I3 an4 lever A an end view of the in-v e same degree of heat. I pro- A,of the balance lever uis ,cally connect, a battery,
end of the balanced lever with4 the battery, a relay,
thermostat K which is disposed within the incubator chamber. I
The action ofthe mechanism is as follows: When the incubator chamber reaches the which the thermostat is adjusted,
Lever A iii turn pulls with it rod B which is connected with lever C through a knife-edge contact at thumb nut E. As rod B moves downward the `end of lever C moves upward until it no longer touches the mercup F. The primary circuit thus being open, the electrical magnets are released and the circuit to the heating element N is opened which allows it to cool olf.
As the inside of the incubator cools down again about one-tenth of a degree, the lever 1. In an electric incubator, the combinationv of an incubating chamber, 4insulating members at opposite sides thereof, a resist-- ance wire connected back and forth on the insulating mem-bers, a thermostat, a balanced lever operatively connected with the thermostat, a cup o mercury with which one end a wire connecting the opposite i awire from the battery to the primary terminal of the relay, and means'for electrically connecting the relay with the service mains and the resistance wire.
