No. 577,109. Patented Feb. 16,1897.

UNITED STATES PATENT OFFICE.

LOUIS J. MORGAN, OF INDIANAPOLIS, INDIANA."

PUDDLlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 577,109, dated February 16, 1897. Application filed June 18, 1896. Serial No. 596,055. KNo model.)

To all whom it may concern-- Be it known that I, LOUIS J. MORGAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Puddling-Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in that class of tools used for stirring the molten mass of metal in puddling-furnaces, and more particularly to improvements upon the puddling-tool of Patent No. 550,368, granted to Henry B. Hall and dated November 26, 189-5.

The puddling-tool heretofore in use is so constructed that it becomes necessary, after the charge in the furnace has been sufficiently puddled, to remove it by means of tongs or other suitable devices from the puddlingchamber and to replace it in the puddlingchamber before the introduction of a new charge, whereby considerable time and labor are expended.

The object of my invention is to provide a puddling-tool whereby I am able to dispense with the removing and replacing of the tool, as above set forth, thereby saving time and labor.

A further object of the invention is to provide a puddling-tool that will be much lighter in weight than any of those heretofore used, thereby enabling me to use less motive power than formerly required in rotating the tool.

The invention consists, essentially, of a puddling-tool within which water is made to circulate while the tool is in operation, and also of the novel features of construction hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings, Figure 1 is a central longitudinal section of the preferred form of tool in position, with the middle chamber of the puddling-furnace shown in section. Fig. 2 is a transverse section of the stirring bar or tool, taken on the line 2 2 of Fig. 1. Fig. 3 is alongitudinal section of a modification of the tool; and Figs. 4 and 5 are respectively side views, part1 yin section, of still further modifications.

Like letters refer to like parts throughout the several views.

In the drawings, A denotes the walls, and B the roof of the middle portion or puddlingchamber of a puddling-furnace.

C is the hearth of the puddling-chamber, and D the bottom plate thereof. Resting upon suitable supports E F is the door or outlet of said chamber.

The stirring bar or tool is made of iron or other suitable material and adapted to rotate on the bottom of the puddling-chamber. This tool may vary in thickness, width, and shape. It may be provided with ribs b on the bottom, as shown in Figs. 1 and 2, or it may have a smooth bottom, as shown in Fig. 3, or it may be made in a tubular form, as shown in Figs. 4 and 5.

All the various constructions of the tool, as illustrated in the drawings, are so constructed and arranged that water may be circulated within the tool, as hereinafter de scribed, and thus the tool be kept cool during the operation of puddling.

The stirring-bar, as shown in Figs. 1 and 2, is made of one piece of casting, comprising the shell or outer portion a, provided with an interiorly-screw-threaded nipple a and a cen tral portion a having an interiorly-screwthreaded nipple a and provided with holes or openings a which latter permit the water to circulate, as hereinafter stated.

In the construction shown in Fig. 3 the stirring-bar is made of a single hollow casting provided with the interiorly-threaded nipple a. In place, however, of the central portion ct of the construction last above described there is substituted a water-circulating pipe consisting of the parts c, screwed into a plumbers T-joint 0 In the construction of Fig. 4 the tool is built up of pieces of ordinary plumbers pipe cl d, T-joint cl, nipples 01 CF, and caps d d",

and contains within it a water-circulating pipe similar to that described in connection with Fig. 3.

In the construction shown in Fig. the tool is built up similarly to that of Fig. 4:, that is, with the pieces of a plumbers pipe 01 d, T- joint d, and caps 02 d omitting, however, the nipples d d In this modification, Fig.

Ioo

5, the inclosed water-circulating pipe is shown as being made of lead, rubber, or cloth hose or other flexible tubing.

c is a shaft made of hollowpipe or tube of iron or other suitable material, which revolves in a suitable bearing 6, located in the top of the roof B of the puddling-chamber. The lower end of this pipe is attached to the nipple ct, Figs. 1, 2, and 3, or to the T-joint d, Figs. t and 5, by screwing the same into said nipple or joint, as the case may be. I do not hereby,however,intend to limit my invention to this means of connecting the shaft 6 with the stirring-bar, as it is obvious that any suitable means may be employed without departing from the spirit of my invention, as long as such means of connection permits a sufficient grip for rotating the tool. The upper end of said shaft is closed by the collar '9 and revolves in the bearing 6 made integral with the support f.

g is a pipe or tube made of iron or other suitable material located within the shaft 6 and adapted to rotate with it. The lower end of this pipe is attached to the nipple a Figs. 1 and 2, or to the T-joint 0 Figs. 3, 4, and 5, according to the construction of the tool to be used. The upper end of this pipe fits into a sleeve g.

his an outlet-passage from the shaft 6. i is a pan surrounding said shaft, and'k is a waste-pipe.

Z is a cog-wheel rigidly fastened to the shaft 6, adapted to mesh with the cog-wheel m on the shaft 91, to which power may be transmitted by any well-known means.

0 is a lever fulcrumed at 0.

The operation of the device in so far as has not already been described is as follows: When power is applied to the shaft n, the shaft 6, together V$ ith the pipe (,is caused to rotate, thereby causing the stirring bar or tool to rotate within the puddling'chamber and stir up the molten mass of metal. During this operation of puddling water is introduced, preferably under pressure, into the top of the pipe g. wardly through the said pipe into the bottom of the tool, Figs. 1 and 2, thence upwardly in the direction indicated by the arrows through the outlets hinto the pan t' and off through the waste-pipe 79. In the construc tions shown in Figs. 3, 4, and 5 the water flows out through the ends of the pipe within the shell or outer portion of the tool and passes upwardly in the direction indicated by the arrows into the hollow shaft 6 and off through the waste-pipe 7c in the manner already described. After the charge has been sufficiently puddled the shaft 6, together with the pipe 9 and the puddling-tool, is lifted up to allow the puddled charge to be withdrawn and a new one to be introduced by raising the lever 0. When the lever 0 is lowered, the tool resumes its proper position on the bottom of the chamber.

The circulation of water within the shaft The water flows down-' a and tool prevents them from becoming heated during the process of puddling, and it never becomes necessary to remove the tool from the puddling-chamber, besides permitting the tool to be made of material much lighter in weight than that of the tools heretofore in use.

What I claim as my invention, and desire to have protected by Letters Patent, is-

1. In a puddling-furnace or other like structure, the combination of an upright tubular shaft with means for rotating the same, an inner tube in the shaft with means for supplying water thereto, a horizontal hollow stirring-bar or shell, firmly secured at its middle point to the upright shaft with the interiors in free communication, an inner hollow horizontal portion located within the said stirringbar or shell, having terminal outlet-passages,

and centrally connected to said inner tube with the interiors in free communication, whereby when water is introduced into the inner tube it will circulate through the inner horizontal port-ion and thence through the shell or stirring-bar, and outward through the upright tubular shaft, while the latter is rotated, substantially as and for the purpose specified.

2. In a puddling-furnace,or otherlike structure, in combination, an upright tubular shaft c, with means for rotating the same, having centrally affixed to the bottom thereof a hollow stirring-bar or shell, containing a horizontal hollow member with terminal outletpassages, an inner tube 9 located in the tubular shaft 6, and means for supplying water to the same, said inner tube firmly secured to the middle point of the said tubular portion within the said stirring-bar or shell, whereby a water circulation may be maintained through tube g and the said tubular portion within the stirring-bar, and thence outward through the said stirring-bar and the tubular shaft e, while the latter is being rotated, and the stirring-bar thus kept cool during the puddling operation, substantially as and for the purpose specified.

3. In a puddling-furnace or other like structure, the combination of a stirring bar or plate comprising an outer portion or shell to, provided with a central portion as a made integral with said outer portion and having an outlet as a ahollow rotary shaft provided with an outlet, a tubewithin said shaft, connections between said shaft and said outer portion and connections between said tube and said central portion whereby water may be circulated within said stirring bar or plate, and means for rotating said shaft, substantially as described.

In witness whereof I have hereto affixed my signature, this 3d day of April, 1896, in the presence of two witnesses.

LOUIS J. MORGAN.
