" INCUBATO R.

SPECIFICATION forming peut of Letters Patent No. 364.073, dated May 31l 1887.

Application filed November 15, 18H3.. Serial No. 218.846. (Noniodol.)

To all whom it may concerlu- Be it known that we, CHARLEs E. WILLIAMS, of Fall River, in the county of Bristol, State of Massachusetts, and JOHN F. GARR, of Tiverton, inthe county of Newport, State of Rhode Island, have invented a certain new and useful Improvement in Incubators, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a vertical longitudinal section showing the heating device ofour improved incubator, some of the parts being represented in side elevation; Fig. 2, a top plan View of the same, and Fig. 3 a vertical transverse section.

Like letters of reference indicate corresponding parts in the different figures of the drawings. I

Our invention relates more especially to that class of incubators in which hot Water is employed for maintaining heat in the hatchingchamber; and it consists in certain novel details of construction, as hereinafter fully set forth and claimed, the object being to produce v a more effective device of this character than is now in ordinary use.

i The nature and operation of the improvementwill be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body or case, which is provided with the usual airspaces or insulating-chambers, x.. A n -shaped boiler, B, is disposed in one end of the body, and provided at the top with a series of eduction tubes or fines, C, and at the bottom with induction-tubes H, through which the heated water circulates. A smoke flue or pipe, D, leads from the upper portion of the boiler directly through the side walls thereof, said pipe extending horizontally along the body A and opening into the chimney E.

Vertically-arranged pipes m connect the cduction-pipes C with the induction or return pipes H, near the chimney E. A verticallyarranged pipe, K, is connected with one of the tubes or lues C, into which it opens, said pipe being provided with a short branch pipe or nipple, z. vA flexible rubber tube, Mis attached to the nipple z, said tube being provided at its outer end with a cup, Z.

Bivoted at r, in the upper end of the pipe K, with its longarm secured to thecupl, there is a horizontally-arranged lever, N, provided y at one end with a counterbalance-weight, J, and jointed at its opposite end to averticallyarranged rod, Q. A lamp, R, -is disposed bcneath the boiler B in such a position that the l being lighted, the water in the boiler' will be' heated and pass through the eduction-tubes C, down through the tubes m, and thence through the return-tubes H into the boiler again to be reheated.

In case the water in the boiler becomes too hot, or the heatin the incubator too great, the water will be forced into the pipe K, and thence th ron gh thenipple z and tube M into the cup Z, the cup being so arranged that the long arm of the lever N, which is secured thereto,'will rise and fall as the cup is raised or depressed. It Will be obvious that when the temperature rises and asufficientquantity of water is forced into the cup to depress it the lever will fall ac-v boiler will fall, and the water in the cup Zow v out of the same, thereby permittingthe cup and lever N to be raised by the counterbalance-weight J, the rod Q being at the same time drawn upward, the sleeve t depressed,

` and the iiame of the lamp increased. It will therefore be seen that the pivoted levers N b, roo

counterbalance-Weight J, sleeve t, rod Q, pipe K, and elastic tube M, provided with the cup l, constitute adevice by which the heat or ternperature of the water in the boiler` and pipes 5 is regulated automatically.

By constructing the boiler with the air-chamber k, and carrying the pipe D from said cham- `ber .through the body A, the heat generated by the lamp is utilized to the best advantage. lo An auxiliary spring may be used in connection with the tube M, if necessary, and the tube K be inserted directly in the boiler, instead of in the pipe C.

As our improvement relates especially to i 5 the construction and arrangement of the boiler and its pipes, and to means for automatically governing the temperature of the water, it is not deemed essential to show any other `parts oftheincubator than are represented in the 2o drawings.

end of said Ainverted-U-shaped boiler, said 5ov smoke-pipe passing through said case into the chimney-flue, substantially as described.
