METAL MEETING AND POURING DEVICE.

Application filed October 9, 1924. Serial No. 742,665.

To all whom t may concern:

Be it known that I, VILLIAM M. BowLEs, a citizen of the United States, residing at Shawnee, in the county of Pottawatomie and State of Oklahomahave invented certain new and useful Improvements in Metal Melting and Pouring Devices, of which the following is a speciticationf This invention relates to improvements in 4devices for melting and pouring precious metals suoli as are used by manufacturing ljewelers in casting rings, bar pins, and other articles of jewelry.

One of the objects of the present invention is to provide a device of this class which may be conveniently employed. in casting various articles of jewelry, 'the device embodying` means whereby the metal of which the ar- -ticle is to be made may be readily and conveniently melted, and means for supporting -the mold, in a manner to permit of ready pouring of the molten metal thereinto.

Another object of the invention is to provide a device of the class described embody? r ing means for supporting charcoal blocks of various sizes in which cavities of different sizes may be formed to constitute crucibles in which the metal may be melted, the support for the said blocks being provided with means for supporting the mold flask in such position that when the device as a whole is tilted, the molten metal will be discharged from' the ciucible directly into the throat of the iask, thereby greatly simplifyingl the handling of the metal and its reduction to a molten state.

In the accompanying drawings:

Figure l is a perspective viewof the device embodying the invention, the crucible block and the mold flask-being vsomewhat` displaced with relation `to the device proper to better illustrate the structure of the latter. y v

Figure 2 is a vertical longitudinal sec- V tional view taken substantially Aon the line 2-2 `of Figure 1, looking in the direction indicated by the arrows. f

Figure 3 is a view similar to Figure 2, illustrating the device tilted in the act of pouring the molten metal from the crucible block into the mold flaskY Figure 4 is a vertical transverse sectional view taken substantially on the line 4 4 v 'of Figure l, looking in the direction indicated by the arrows.

Figure 5 isl a view in elevation of one section of the mold ask.

llhe device comprises a base l lupon which l'is lined an upstanding pedestal 2 which may be of woodor any other material found suitable for the purpose and which supports, at its upper end, the supporting means for the crucible block. The said supporting means comprises a pair of sections, one indicated in general by the numeral 3 and the other in general by the numeral 4. Each section comprises a plate 5 provided along one longitudinal edge with an upstanding liange 6, and bars 7 are secured to the under side of the plate 5 of the section 3 and extend beneath the under side of the plate 5 of the section 4 and are provided at their last mentioned ends with downwardly turned portions constituting ears 8 through which are engaged bolts 9, the threaded Shanks of which lit through openings in ears 10 secured to the under side of the said plate 5 of the section 4, wing nuts 11 being 1 threaded onto the shanks of the bolt-s and being adjustable to slide the ears l0 along the bolts and thereby bodily adjust the section 4 rin the direction of the section 3, the flanges .G yof the sections being in `this manner, brought Vinto clamping engagement with opposite sides of the Crucible block which is indicated by the numeral 12. The plate 5 of the section 3 is secured by screws or other similar fastening elements 13 to the upper end of the standar-d 2 and this section is, therefore, permanently fixed, it being understood that the section 4 is adjustable upon the bars 7 through the medium of the bolts 9 and'nuts l1, in the manner above outlined. c

The mold support is, generally speaking, of rectangular form and it will be observed by reference to the drawings that thel cru- -cible block 12 is likewise of this form and bis designed to-be disposed above the upper `sides of the plates 5 of the two sections of the support and, as previously stated, to be clamped between the flanges 6, ...when the wngnutsllare tightened. The block l 2 the molten metal when 'poured from the lso Cil

into' the throat of the-mold.

tained in substantially per ,instal deli verd concavity 141-, as will hereinafter be eX- plained.

Then the device is tilted to pour the molten metal from thev concavity M through the spout l5, it is intended that the metal shall be deli-veredto the mold in which the ring or other articleV is to be cast,y and in order that' the i'nold' may be supported in position to receive the molten nieta-l, means is provided which will now be described. The numeral 16 indicates a rectangular plate of metal which is provided withy upstanding ears l? at its upper edge, and bolts 18 are secured throughsa-i-d ears and adjustahly through slots 19 formed in hinge leaves 20 hingedly supported as 2l from the plates of the sections 3 and e of the cruc-ihle block support?, the plate 1G 'depending substantiah ly in a vertical position, as shown in`= FigL ures l, 2 and 3 of the drawings. A tray 22 of substantially recta-ngi'ilar 'form and comprising a bottom 28 and a' surrounding rim 24, has secured to the underside of its bottom a bracket member Q5 carrying a threadedstud 26' which projects through a slot 27 formed vertical-ly in the plate 11G.

' A nut 28 is threaded onto the stud 26 and may be tightened to hold-the tray 22 at dillerent elevations. The mold is indicated by the numeral 29 and compri-ses twoV sections 30 of charcoal, the opposing or meeting farces of which sections are formed with 1grooves or channels or recesses 31 of a contour to produce an article of the reqi'iire'd shape, and the said faces o't the mold sections are likewise formed with grooves opening through their upper edges, which grooves register, when the sections are assembled, as' to constitute a `throat intoivhich thevmolten metal may be poured to enter and fill the grooves or recesses 31. In practice, tlleniold 29 ivi-ll be interposed in thetray and? after the metal in the co'ncavity lfl has been reduced to'famolten state, the entire device 'may he bodily tilt-ed, as shovnin Figure 3 of the" draiaf'ings, so 'as to discharge the molt-err metal from the concavity and. through the sgroove or channel lt will be observedby reference to the said Fig-ure 2l, that after the device is tiltedg-the mold supportand the mold tliereemwvill he mai-nendicular position so that the throat of the mold will at all tunes pdsitioito receive the' molten Ongi;

In order that the metal within the con cavity 14 may be reduced to a molten state, a strip 33 of a metal which is a good conductor ofeiectricity, is securedto one side ot the pedestal 2 and has its upper end deflected outwardly to provide a contact finger 3dr- Which engages firmly against the under side ot' the plate 5 'ol' the section e' ol' the cruc'ible block support. A conductor Wire 35 .is connected by a binding post 36 to the strip 33, and a second conductor Wire 3'( is connectedto a carbon rod 38 provided with a hand grip 39. The Wires 35 and 37 lead from a source oi current supply and it will beevident that when the handle 39 is grasped and the tip of the carbon rod 38 is brought into Contact with the `metaal scrap in theconca-vity' 14; the circuit will be closed and the metal will be reduced to a molten Having thusdeseribe'd the invention, ivhat I claim is:
