MoLn-Y App1 ica tion fire March 10, 1921 S erial No. 45i,25i.
To whom mom.-
7 Be it known that I ALF-PIPPING, a citizen i of the United States, residing at Altoona,
in the county of Blair and State ofiPennsyl- Vania, have invented certain newanduseful,
Improvements in Molds, 'ofW-hich the following. is aspecification. 1
This inventionrelates to' metal founding. A primary object is to provide improved means whereby special castings can be produced through the use of a special mold made up to retain its shape after the casting has been removed, thus obviating the necessity of building up anew mold prior to the pouring process.
Another object of this invention is to produce a mold that is readily changed in shape to roduce different shaped castings.
still further object of this invention is to provide a moldthat is made up of a plurality of units which are adapted to be readily positioned in a vertical plane and clamped in position by a pressure broughtto bear upon them in a horizontal plane.
With the above and other objects in view which will be more readilyapparent as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts as will be hereinafter pointed out fully, illustrated and claimed. It will be readily understood by those skilled in the art to which this invention belongs that the same is quite susceptible to various changes or modifications without departing from the spirit or scope of the'invention but a preferred and practical embodiment of the invention is shown'in the accompanying drawings in which:
Figure 1 is a vertical longitudinal sectional view of the present improvements;
showing the rods or wires on an enlarged scale.
Figure 2 is a horizontal sectional view of the construction shown in Figure 1.
Figure 3 is a vertical cross-sectional view.
t lledrag ll, the drag is provided- With' 7 means for forcing all the rods or wires 10 together, such thatfwhe'nthe pattern "12 is removedthe shape of the pattern remains imbedded in the 'surface- The means for' bringing pressure upontherods. '10 maybe broughtabout in several different ways but a 'simp'le" method is shown wherein a mow I able end 13 "of the drag 11 iscon'nected with a screw 14 which passes through the side 16 of the drag.
A the Screw either away tighten or loosen the rods 10 in the drag. 5 Having thus formed the mold int-he drag the protruding ends of the rods being cut offbefore the sameisturned over leaving the face of the pattern uppermost. The other i half of the pattern is then superposed upon the lower half and the cope 17 is placed onthe drag as shown in the drawings- An earthen tube 18 is then placed above one portion of the pattern and the rods '10 are then dropped in and around the top half of the pattern. This having been accom plished the rods are tightened in place through a device similar'to the one attached to the drag. The cope is then removed from' i i r the drag and the patternremoved fromboth the cope andthe drag. After :thisis done a facing F of sand with a mixture of-loam f may be spread over the surface whereinthe pattern rested, in order to prevent the molten metal from welding tothe surface of the rods 10, during the process ofpouring; This facingi S is of course only necessary- When metal is being molded'and therods 1O areof metal to prevent adhesion ofmetal to metal. When molding celluloid, wax or rubber, such facing will not be required;
Before the pouring is accomplished some molding loam; should beplaced around the i top of the tube18 in order to prevent the metal which naturally will fall around the tube from amalgamating with the metal in the rods 10. 1
It will be quite readilyunderstood that' the same as ifthe copeis used.
It will be bserved that this invention is r applicable to the use of producing castings reverse. of the pattern, the latter'being ac;
this invention is applicable to molding castings in the drag only in which case no flaskis. needed and the mold is faced in'this case 9 i regular way in which certain of the rods 1 v are then cut away and the rods thus out are pushed back toward the mold. board. The.
outline thus formed is the reverse of the pattern and castings made in this mold Will be the reverse of those made fromthe pattern.
I claim: 1. A mold forming device including a drag, a movable end in the drag, means for moving said end, a plurality of relatively small rods adapted to be positioned. in the drag, a pattern for forming a mold v of said rods pro ect 1ng beyond the drag With the rods, and a facing for the mold.
2. A mold forming device including a drag and cope, means for forming a mold chamber consisting of a plurality of rods arranged parallel to each other Within the drag and adapted to be. shifted longitudinally to conform to the face of; a pattern While loosely held in the drag, and means forbi ding therods together to hold them rigidly'in set moldin o'osition, the portion after setting being out off.
