Title: Process of Perfecting Cast-steel Ingots.
Inventor: HUNT ROBERT WOOLSTON
Filed: 1903-11-03
Granted: 1903-12-17
Abstract: 23,819. Hunt, R. W. Nov. 3. Ingots.-When casting a steel ingot, especially one used for rail manufacture, a steel bar, rod, or piece, heated and of superior quality if desired, is forced axially into the ingot after a top crust has formed and while the body of the ingot is still molten, so that the bar becomes incorporated with the ingot, pressure being exerted simultaneously on the top of the ingot. In the apparatus shown in Fig. 1, the rod 5 is driven out of a guiding- piece 6 into the ingot by the piston-rod 15 of a power cylinder 13, and pressure is exerted on the top of the ingot by the whole or part of the weight of the cylinder 13 and its frame 7 acting through the piece 6.

Granted: 1904-04-14
Abstract: 791. Nash, N. E., and Friedman, W. B. Jan. 12. Thermostats.-Relates to apparatus of the kind in which an expanding piece opens or closes a vent in a passage by whih compressed air is led to a motor, which actuates a valve controlling the supply of steam or hot water to radiators. The compressed-air inlet B and outlet C, in the shell A, are connected by channels a, b, to a chamber D, which is in connection with the outer air by a port L and an outlet N. The channel a leads to a channel I, provided with a regulating-valve, and passing into a Bourdon spring bent over and fastened to a piece 0, to the end of which a valve stem is adjustably fitted. This stem passes through the wall of the chamber D and carries a rubber valve which, when the spring is not distended, closes the inlet of the channel a into the chamber D. The nickel and porcelain expanding piece P, the nickel of which is cut away to expose the porcelain to the atmosphere on both sides, is screwed to the bottom of the shell, and, at the other end, is provided with a hollow regulating-screw containing apiece of raw hide or like substance which normally fills and stops a nozzle n, opening from the interior of the Bourdon spring. The apparatus is adjusted to maintain any desired temperature. When the room is below this temperature, the nozzle n is opened, the spring relaxed, and the rubber valve closes communication between the compressed-air inlet and the valve-motor outlet ; the valve thus remains open and steam or hot water passes into the radiator. When the desired temperature is reached, the piece P contracts so that the nozzle n is closed and the Bourdon spring distended, and compressed air passes to the valve motor and closes the valve.
