SPECIFICATION forming part of Letters Patent No. 320,626 dated Feebrnary $1, Application filed February 7,1898 Serial No. 869,291 (lie model.)

To all whom it may concern:

Be it known that I, RODERICK W. DAVIES, of Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Casting Apparatus;

and I do hereby declare the following to be a full, clear, and exact description of the in- VeIltiOD, such as will enable others skilled in the art to which it appertains to make and I0 use the same.

This invention contemplates certain new and useful improvements in machines for casting molten metal.

The object of the invention is to provide an improved machine having molds into which the molten metal can be poured, and thereby formed into pigs,and after being solidified dis charged automatically fromsu'eh molds.

A further objeotis to provide molds having to a plurality of independent chambers forsuecessively receiving the molten metal. The molds are. arranged side by side on a circular carrier or wheel which is gradually revolved. The molten metal is supplied to the u pwardlyfaced chambers of two or three molds at a time from stationary ladles, which may be connected direct with a furnace by suitable runners. Suitable deflectors, mounted on the carrier and extended longitudinally over the molds, prevent the molten metal from outer ing between the several molds.

' The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan view with some of the partsomitted. Fig. 2 is a cross-sectional view on line 2 2, Fig. 1. Fig. 3 is an enlarged View of one of the molds. Fig. 4 isa-crosssectional view 0 on line 4 4, Fig. 8. Fig. 5 is a similar view showing a slight modification. Fig. 6 is aview of a second modifiation. Fig. '7 is an enlarged detail view showing one of. the shields.

Referring, to the drawings, A designates a circular carrier in the form of a wheel. This is composed of a series of I beams a, radiating from a hub a and united near and. at their outer ends by inner and outer concen- 50 trio rings a a The hub of is supported by a shaft a, extended base-plate a having a ho modate said shaft. From carrier depend a series of support the journals of wn s which travel. on circularlyr1 mounted on a snimhle foam preferred means ay ally revolving the B? at V, Fig. 1, motor m, Fig. 2, which with to der side the outer ularly from a to QMJQOBR he of the which tangular shape and u rs or formed with opposite aha of substan tially said chai'niicrs enter. ii each mold. or n mold with concave chambers to the ehanihers b These molds are mow. ed on. carrier-A side by side. From the ends oi each. mold projects a stud if, (or a continuous shaft may be used,) said studs hitting in bearings 12 on rings a a Fromtheouterstud oi? each mold project opposite lateral arms Q. As the car ier is revolved after tho upturned chambers of some of the molds have been supplied with molten metal the downwr diyprojecting arm C will contact with a station ary post D, located. outside of but close to the line of travel of the circumfcr -ial r As the lower arm of a mold th us ontaets said post the mold is given a partial or qua her turn, the weight of 't' epig sex-vi in turning the mold like emptying the pig from the mold a" the previously downwardly-faced cl? 1." cavity to face upward.

W hat has been said applies as but two diametrically-oppoced chan b i or caviti" 5 of a mold are employed, hut when, as is fcrred, each of ,the four independent hers or cavities of each mold are to successsively receive the molten metal it essential that in dumping the pig therefrom one should make but a quaflentnrn. lions shown in. Fig. 5, four arms d laterally from the outer stud of stead. of but two arms, be

againstuocidentsl turnd", inst at one end on the enter 1 V he free crd of ezgoh springm-m. bears downwardly on toe ..ttened portion of u cl" on the outer end of. each meld. When each mold is provided with but two dumping-arms, i" boss tZ has but two flattened portions with rounded ends, (see Fig. 3 but when such mold is tobe given but quzirtenturn in dumping the pig therefrom d four at ruled v, it four flattened portions in the form cl 2-; square. (See Fig. 5.) In lieu of prouding the several molds with dumpingerms a gear-wheel f they made fast on the outer stud of each 1nold,so as to engage with tectlif on the upper end of the dumpost. (See 6.) In this form the exwhich each mold is to be turned that ther it is to be given a quarter-turn or rndepends upon the number of rack- The molten metal is simultaneously supplied to n plurality of molds, being emptied therein from spouts (1 leading from ludles (i which are supplied with molten metal direct from fuinsce Z by nrunncr (1, having hrenclies 2 Each spout (7. opens directly shove the line of travel of deflectors E,(sonie of i rich are shown in 1,) extended loninclly iurvs rd over the molds and serving to prevent the molten metal from falling sen the letter. These deflectors consist of 1 ver'ted'h burs,.snpported at their outer byposts or uprights e, positioned on the circular carrier.

1.1L spouts ties the molten metal will be depostnc inolds as they pass beneath the or the lcdles, the carrier being revolved rate of about ten feet to the minute:

but this speed may be varied. The pourof the met-cl continuous until the supexhausted, and the rotstion of the moldlei" like "ice continuous. As the filled molds travel toward the point of discharge (the carrier being moved in the direction of the arrow 4)) they may be sprayed with water to oid in cooling the metal, so that a. solid pig i oedelivered at the point of discharge. ouch inold reaches the latter point its dcpending; nrm' will contact with the post I), resulting in the turning of the mold and the dumping of the pig therefrom. When out two arms are provided for each mold, the latter is completely inverted by the contact of arm with the post, aided by the weight of the pig, causing its previously-lowered side to be faced upward to receive the molten motel when the mold again comes beneath the discharge-spout of the lsdles; out when it is desired to successively use the four chambers or cevities of each mold as receivers for the molten motel the some will be given but e quarter-turn and the pig will fall therefrom lght. Thus it will be seen that ceived. in the several molds in a.

molten s etc is discharged solidified in pigs.'
