A broad patent was granted on this machine May23d, 1882. haights patent incubatoris the invention of Henry J. Haight, of Goshen, N. Y. We haveno full description of it, Mr. Haight, not yet having placed themachine on the market; although rather complicated it is saidto achieve good results. It is regulated by a thermostat. The egg-tray is worthy of particular mention; it is a rack. Fig. 89.—the acme incubator. (Inside View),covered with course muslin or sacking on which the eggs lie; thisrack is suspended by a bar or axle across the centre, the endsworking in journals; one end of the rack being held in place bya spring bolt. A duplicate rack of same construction is laidover the first and secured to it, thus placing the eggs betweenthe two trays; the bolt is then drawn and the two trays revolve,or turn half of a revolution, thus turning the eggs upside down,and leaving them resting on the sacking of the second tray : thefirst tray is then unfastened and taken off, and the eggs putback in the machine. The machine and turning-rack are both patented. HALSTEDS SELF-REGULATING INCUBATOR. 117 J. M.
