Application filed November 14, 1908. Serial No. 462,646.

cation is illustrated one embodiment of myv invention and which may be the preferred embodiment. Therein Figure 1 is an elevation partly in section on line 2, 2 of Fig. 2, of an apparatus embodying my improvements and Fig. 2 is a front elevation there- 3, 3, of Fig. 2. Figs. 4 and 5 are modifications of my improvements which will be described more in detail later herein. Fig. 6 1s a sectional new on an enlarged-scale on line 1, 1 of Fig. 2. Fig. 7 is a view similar to that of Fig. 6 and showing a modification thereof. Fig. 8 is a sectional view on line 30, 30 of Fig. 1 showing a modification of a detail'of the pouring means.

My improved mechanism is particularly useful for forming into a continuous ribbon or wire such metals or other materials as.

are too hardin their solid state to be conveniently formed into ribbon or wire by squirting through a die asis commonly done with lead, wax and other relatively plastic materials. Heretofore steel, copper, brass and other relatively hard materials have been put through a number of preliminary processes such as casting into ingots, rolling and annealing and the rolling and annealing often repeated before said material *was ready for reduction to wire by drawing through dies.- By means of my improvements such casting into ingots, rolling and annealing and rerolling and reannealing are.

done away with, and the metal or other material whichit is desired to form into a continuous body is oured in its molten state directly into the orm of wire or ribbonyand in one operation is completed or is ready for drawing to smaller size and different cross section if desired.

Referring more particularly to Figs. 1,. 2 and 3 my improved apparatus comprises an annular member 4 normal and rigidly connected as by arms 5, 5 to spindle 6 mounted for rotation in bearing 7 of frame 70. In the inner face of annular member 4.is an annular groove '8 preferably relatively near the front edge of said member 4, so as to be readily accessible for' purposes hereinafter more fully described. Said ring 4 with groove 8 thereln constitutes an annular mold for the reception of the molten material which it is desired to form into a continuous body. Located over said groove and preferably at or nearthe lowest point thereof is spout 9 of funnel or delivery member '10. Said funnel is provided to deliver the molten metal or other'material poured therein to groove 8 of ring however, lowest point of groove 8 as said spout is 4. It is not necessary,

thatsaid spout 9'be directed to the efficient for the purpose specified if directed.

to points in said groove materially distant from said lowest point. Funnel 10 may be supported by any convenient means such as. arm 101 outstanding from frame 70,'or it may be adjustably-m'ounted if desired. Said groove 8 may be of. any desired shape in cross section and I have illustrated it as of U shape that being the nearest approximation to a circle that may be had in an open sided mold that will'allow the removal after solidifying of,the material poured therein.

Also I have found that wireof said U cross section may be readily drawn into .a circular cross section in one operation. Extending rearwardly from funnel 10 in the-direction of rotation of ring 4 I have shown a lip or dam 11, illustrated in cross section in Fig. 6,

having its face in close proximity to'the inner face of ring 4 and covering groove '8. Said dam 11 isefiicient to hold the molten material ingroove 8 during solidification or during the early stages thereof and alsoto keep the air from saidmolten material during solidification. Also'if desired I may form said lipas illustrated in Fig. 7 withportions as 12,-12 entering groove 8 and thereby transforming -said groove from a cross section of U shape toone of circular shape. I

A useful modification of funnel 10 is illustrated in Fig. 8 and comprises a lip or gate 25 extending downwardly and preferably filling in cross section groove 8, and I have provided said gate with a scraper 26. Saidscraper 'may have an upwardly turned lip 27 at one side thereof if desired. Saidgate 25 is useful to prevent the molten material poured into funnel 10 from flowing backward toward plow 15and is also useful to keep the air from the inflowing material. Scraper 26 is useful to scrape from channel 8 any residue that may be left therein by plow 15 and discharge, 1t from said channel.

For removing after solidification the ma- ,terialYpoured intogroove 8, I provide a plow or lifter -15 projecting into groove 8 and ointed in the direction of approach of said ribbon or wire of solidified material. Said lifter 15 is preferably shaped to conform more or less to the shape of groove 8 and preferably has its lip 150 located close to the bottom of said groove 8. Thereby thematerial in said groove is pried up and directed out therefrom in a continuous body.

Flow 15 preferably has its rearward portion 151 formed into, a trough or tube of any desired cross section and may be inclined outwardly so as to lead the material out of the plane of groove 8, so that said material may be conveniently coiled or otherwise disposed of. Also plow l5 isprovided with a deflector 105 thereover to, counteract the tendency of the material to curl upwardly as it passes over lip 150 and direct it into the channel.

of rearward portion .151. Lifter 15 is preferably located circumferentially remote, in the direction of travel of the material-in groove 8, from spout 9 so as to allow a maximum of time for the solidification and cool- I ing of the material before being-lifted from said groove.

. ably mounted if desired but is herein illustrated as fixed to bracket 101.

For controlling the temperature of ring 1 I have provided string of gas burners 13 which may be supplied with gas through pipe 14 from any convenient source of supply. Also Ijhave provided within ring 4: channel 40 through which water or other fluid maybe circulated for cooling or otherwise. Said channel maybe connected with swivel joint 17 of supply pipe 18 by means of-inlet in onefof arms 5;, ,and'discharge Said lifter 15 may be adjust-V inmate from said channel may be had throu h oiitbut as having the inner face thereof inclined at an angle about midway between the horizontal and vertical. In this case the molten material is retained in its seat in groove 8 by the combined action of centrifugal force and gravity. With the arrangement of Fig.

5 the speed of rotation of said ring 4 can therefore be materially reduced from that required in the arrangement of Figs. 1, 2 and 3 or that of Fig. i. I t

I claim .1. A rotating annular internal mold including in combination, centrifugal means for retaining the molten metal in said mold, a gate in said mold having a dam extending into said mold, a scra er on the heel of said dam and a lifter or guiding the solidified metal from said mold.

2. A rotating annular internal mold including in combination, centrifugal means for retaining the molten metal in said mold,

a gate in said mold having a dam extend ing into said mold, a scraper on the heel of said dam, a lifter for guiding the solidified metal out of said mold and a deflector M over said lifter, 1
