IMPROVEMENT lN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 117,569, dated August 1, 1871 reissue No. 4,833, dated March 26, 1872.

To all whom it may concern:

Be it known that we, HENRY M. RULoN and JEssE F. RULON, of Monmouth, county of Warren andState of Illinois, have invented certain Improvements in Steam-Generators, of which the following is a specification The nature of our invention relates to improvements in that class of steam-generators generally known as feed-steamers and the invention consists in the arrangement of a hollow tube spirally encircling a central cylinder, and the whole ysurrounded by a suitable casing and combined with a feed-reservoir, steampipes, and lire-box in such manner as to produce a cheap, portable, and effective feedstealner for the purpose of cooking feed for stock, all as hereinafter fully described.

Figure lis a side elevation of our invention. Fig. 2 is a side elevation of the interior arrangements of Fig. 1, and a vertical section of the outside casing of the steamer.

A represents a hollow cylinder closed at both ends. B is a tube or pipe loosely encircling the cylinder A, its upper end inserted into and communicating with the interior of said cylinder at the point b, and its lower end communicating with a pipe, C, hereafter described. D is an outside casio g surrounding the spiral or worin B and the cylinder A. The upper end of the casing D is contracted and extended upward to form a smoke-pipe, and the lower end, below the spiral B, contains an ash-space, E, fire-grate F, and fire-space Gr. H is a barrel or tank, seated on a suitable support, with its lower end about the height of the lower end of the cylinder A. C is a pipe connecting the lower end of the tank H with the lower end of the cylinder A. I is a pipe connecting the upper end of the tank H with the upper end of the cylinder A. J is a pipe leading from the interior of the cylinder A at its upper end out through the casing D.

The operation of our invention is as follows:

The water is placed in the tank H, and, Howing through the pipe C, enters both the spiral B and the cylinderA until they are full to any point below, say, two-thirds of their height. Fire is now placed in the fire-box, and has free access to all parts of the exterior surfaces of the cylinder A and spiral B, thus utilizing to the greatest extent all of the heat generated in the fire-box Gin heating both the water and steam spaces in said cylinder and encirclin gworm, while, at the saine time, their arrangement is such as to keep up a free circulation ofthe water therein and allow it to rise and part with its steam. The water in the worm, becoming hotter than the water in the cylinder, will naturally rise and flow into the cylinder at its top, and the water in the cylinder, being cooler, will flow out through the pipe C. and into the lower end of the spiral, thus keeping up a perfect circulation and facilitating the passage of the steam to the top of the cylinder A, from which it may be taken by the pipe J and delivered to any desired tank or vessel containing feed to be cooked.

K is a stop-cock in the pipe I, the key of which may be turned to close the pipe Iwhen it is desired to replenish the water in the tank H. L is a check-valve in the pipe C, and, opening toward the cylinder A, will prevent back pressure when it exists. M is a stop-cock in the delivery-pipe J.

We claim as our invention- The cylinder A, spiral B, and casing D, when constructed substantially as described, and arranged to operate with the pipes C, I, and J, and with the tank H, substantially as described, and for the purpose set forth.
