To all whom it moy concern.'
ille itl lmown that I, J/tum E. Siiinirrnn, ii citizen of the, United States, residing in liurnluiiii, leiinsylviiniu, liiive invented cer- 5 tuin linproveniente iii Sto )pers for Metiillouriiig lliiidles, of which die following is ii speciliciition.
llhe objectr of thisinvention is to so construct u stopper used in controlling the tlow of inoltcninetiil frein ii hidle thiit the nietiil rod will not be iiielted during the pouring operation. It is thc iisuul pructice to incose the inetnl rod of the topper within ii irotectiii f shell und the lowerinost section l5 o the i-ihe is in the forni of u 'nphitc stopper head, which incloses the eiiIk of the roi This stopper lieiid acts iis n crucble in the generiil practice und in ii very short tinie the end of the rod or .screw entering do into the stopper bend is melted und, consequently, the stopper luis-i to be removed und n new iito'iper substituted for it. ly my invention nuiteriully increase the life of the stopper, no tluit the stopper ciiii be. used 26 for n iiunihenof heute, whereas heretofore u stoiper would bnrely lustn single lient.
n the'nqxnnpiinyingdrni'in z-Figure l, is 1i vertical sectional View o sutlicient of a stopper und the' bottoni ot ii hidle to Se illusstiute niy invention; ljig. 2, is n sectional view ,of the end of the stopper detached, the section being on the line 2-2, Fig.
und Fig. 3, in ii pliin view of Fig. L.
A is thelmttoni of ii pouring lzidle, iii the present instance of the open lieiirth t pe. l`hiu hulle luie the discluirge openiii which muy be closed by the stopper' ll. iis stop- 'por consists, in the` irewiit instance, of n centi-ul rod C screw threaded iit c. z 40 l) iH-'tho protecting costing for the rod con- .wctng of n series of shells .flanged sd :uiv
to tit one into the other to ineke ii 'broken ioiiil lo prevent the lient from giiiiiiii iieceSS lo the i'oil. 'lhe lower weclion l) is of grzilphite und incloses the end ofthe rod and iw s uiped iis clearly shown in Fig. 2.
.llunuily the screw tlireiid f1 screws directly into n tlireudeil openingI in' the griipliite hhell. but tliiS is found lo lie olijeetioniible,
in the griiphite wectioii forum u ei'ucible when subjected to the lient of the molten inetul und the end of the. rod will be iiiclted in ii very .Qlioi't time, thus `nuihing,r the stop per usi-lese, so thiit'it luis lo be removed und non-conductor between the graphite endl Bectioii D und the threaded end of the rod the rod is not subjected to such intense heet iindwill hist u considerable length of time, e@ und, in fzict, will hist tliroii vh several heats. The nou-conducting nuiterin I prefer t0 use is fire chiy, :is indicated at E, mnd this clay is piicked into iin opening in the grngehite shel W; the openn preferiibly .ing e5 undercut or larger iit tie buse than at the top, so tluit the clny will be confined in the griiphite shell. A. screw thi-eed is molded in the clay und the rod cnn be readily screwed into the threaded o ning e. Other nieuiui of fustening the rod to the cliiy may be iesortcd'to without departing 'from the esesentiiil teiiturenI of the. invention. I find thiit the chiy not only keeps the rod cool enough to pour einy uinount of inetnl from '75 the liidle ut oiie tiiiie, but tluit tlie stop inuy be'nsed screriil t'iines und the clay ai strengthens the. gi'uphite shell because of its x coolingl elloct.
l ehiini:- 80 1. 'lhe eonibiinition in ii stopper fornietul Indies, of n centi'iil rod, n protecting,r shell hui'ing u ginphite end section, with n body of tire chir mounted within the end section of the shell iiiclosin the cndof the rodl so us te protect the ro from the heet of the molten iiietiil.
2.
