MOLDING Asparagus;
1L whom it may concern: I
Be it knownthat I, MADDRA J. Hnwnn'rr,
' a citizen of the United States, residing at Kewaneefln the county of Henry and State of Illinois, have inventeda new and useful Molding Apparatus, of which the following is a specification a The inventlorikir -elates' to a moldingappa;
ra-tus. a
Hereto fore in thetjart of moldin ,cores ,have been made of the same materia "as the mo1d',but it'has'been necessary to form" the core of two halves in separated pattern sections or plates, which are subsequentl fitted novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and edpointed out in, the claims. (1 it being understood that hereto ap n various anges in the form, proportion, size and minor details ofjconstruction, within the scope ofthe claims, may be resorted to without departing from the spirit, or
sacrificing any of the advantages of the'invention.

ther to unite thejtwo halves of t e core paratus is assem ofzthe same. Figs 6- and '7 are perspectiveaviews ofthe sections of the twopart Patented M y so, 1911 respmdin's p rts in all the figures of-the drawings. a x a In the embodimentof the invention illus' I trated in the accompanying drawings, the molding apparatus, which s designed for making a castviron coupling, comprises in w its construction flask sections'l and 20f a two-part flask, and a pair of combined at: tern and core box plates 3' and 4. t The ask sections]; and 2 ,are similar in construction with the exception that the lower section or drag is equipped verticalghide'pins 5, and the upper section or cope is rovided" with lateral y projectin ears or anges 6, having openings 7 for ifiie reception ofthe guide pins 5, but either flask section may be.
equipped with theguide-pins or either section may be arranged at the topjwitho'ut affecting the operation of theqapparatusl The guide pins 5 are preferably connected wi 11 the flask section 2b means of flanges 8, corresponding withzt e ears orflan es 6, but the guide pins may be mountedon t e section in=any other defsiredmanner, H
The combined attern'and core'box plates,
whichareprovi ed at their, side edgeswith notches 9 to receive the his '5, are each composed of" straight flat si eportio'ns 10 and a central pattern portion 11', having an exterior configuration" to form 'onej half of the pattern in the sand of theaggacent section and having an interior co tion to form the'core 12. Tha -notches 9,
,which are formed in the'flat outer" rtions of the plates 3 and 4, register with t a openings 7 of-the ears or flanges 6, and the-combined pattern and core-box platesare inter locked with' the idej'pins' 5 when the apled. When the plates 3 and 4 are fitted togetheigas illustrated in Figs. 2 and 5 of the drawings, they form 'a core box, which is adaptedwhen filled with sandto produce the core 12. The core'box- @formed by the plates is open at its ends, and both the core and the flask sections are v adapted tobe filled withsand to rm-m simulv ,taneousl the core 12 and the sand mold 13. The flas sections and the corebox ma be rammed-up byhand, but it isfpreferab e to apply the sand to the a paratus to form both the sand m'old andtlie core simultaneously by means of a pneumatic machine, and
molding apparatus arranged in a machine 14, a portion only thereof being illustra'ted,
,in Fig; 1 of the drawings, I have shownthe As these machines are .well known in the art, a further descriptionand illustrationthereof After the sand has box plate 3, are removed from the lower sec" 'tion, and the plate 4 is inverted, the parts of the-apparatusioccupying the positions shpwn in Figs. v6 and 7, the completed core 12- being supported by the plate 4.' The plate 3 is then removed from the flask section 1, and
the latter is replaced onthe lower section, it being supported by the section? to the top. The flask section 2' with its plate 4. is then removedfrom over-the section 1,,thecore being supported by the section 1 inend recesses 15 thereof in proper '25 position with relation to the molding sand of the said flask section 1. The plate 4 of the flask section 2 is then removed and the flask section;2-,i s then 'replacedonthe' flask section a 1. {,Ehesand mold and the: core are then in proper relationfor castin Thesprue hole is formed in. the .usual'manner, but as this detail is well known in the artof'molding together with the manner in which the flask sections are fitted together and arranged for castin I after the pattern plates have. been removed, further explanation of this portion of the operation is un- 1 necessary, The flask section 2 is-provided at its upper, edge with registering pins, 16 for engaging perforations 17' of the pattern plate 4, and the other section 1 and the pattern plate 3 may have corresponding pins and perforations, The comblned, pattern and" core boxpla ars provided at the, terminals and outer semi-circular or approximately semi-circular, faces 18 and 19. When the-v plates and the flask sections are assembled, the outer faces 19 fit in the recesses or seats 15 of the flasksections 1 and" 2, and the inner faces 18 former shape the ends ofthe core to .fit the recesses of the flask sections, so that as the flask sections are successively placed over the ends of the form andarranged formaking only a S111 gle article, but it will beireadily apparent that the apparatus may be constructed to make a plurality of 'molds and cores, the
number being limited only by the capacity plated. The 20 apparatus is then inverted to bring the flask of the -'core,;- :b,ox with corresponding innerof the machine for applying the same when the apparatus is used in that manner.
The flask sections are provided at one end with openings 20,;vhich are arranged at the top when the apparatus is placed 1n the ma- 7o "chine 14,- in order to receive the sand fromthe sand pocket 21 thereof, but sand ma be introduced into the flask sections throng any other arrangement of openings, the latter being provided to correspond with the construction of 'the machine with which the apparatus is employed. The core box 'formed by the inner faces ofthe plates 3 and 4 are open at the ends, and sand is readily introduced into the same to form the a0 5- core, it. v
The simult neous formation of 'both the sand mold ,a d the core of green sand thro ilgh dne diieration and the ready remqjia'l Eff t e combined pattern and core box '85 plats greatly lessens the labor and expense .ofImakmg cores and sand molds and results in the rapid construction of perfectjcores and molds. .a
. Having thus fully described inven- -tion,. what I claim as new and desire to se-" cure by. Letters Patent, is V I,
1. A molding apparatus including'a secs ,tional flask, and combined pat-tern andc'ore boxplatiasfit-ted together to provide a core box and arranged betweenthe flask sections 1 to formimoldsthelein, said' core -box being open and the flask being also provided at .such open portion with a fillin opening'to j enable a complete mold and flas to be filled simultaneously without changing the apparatus. 2.
