nasse TM'EDTATES Fries.
` f .eeoeeefnoss or NEWPORT, KENTUCKY'.
Specification forming `part of Letters Patent No. 112,286, dated FebruaryV 28,1871. d
. "I, GEORGE Ross, of Newport, Campbell county, Kentucky, have invented a new and useful Mode of Molding and Casting Pipe-,El-
- bows, ofwhich the following is a specification:
N @ture and Objet/'tof the Intention.
My invention consists in molding and casting pipe-elbows lin such a manner as to dispense with the customary anchor or prop that has heretofore been employed for supporting the core in the mold, the details of which mode of molding and casting will be hereafter fully described.
General Description with reference to the Dram?-V ing. Y
Figure 1 is a perspective view of a pattern such as is employed when four4 elbows are to be cast in one mold. Fig.2 is a perspective view of a core corresponding with the above pattern. Fig. 3 is a plan, showing a portion of either the cope or `drag after the pattern has been removed therefrom; and Fig. 4 shows a portion of the `flask after the metal hasbeen poured, the core and casting remaining in the iiask.
NVhenever it is desired to mold and cast four elbows at one operation I :provide a pattern similar to that represented in Fig. 1; and it will be seen that said pattern consists of four similar elbows,jA,-B,` C, and D, which, are
placed sofas tooccupy the fourfsides of a square; and the* ends of these elbows are united by diminished portions `andF F to serve as `core-prints. The members A B (l` D and E E and F F" shouldbe so united as to form one completefand inseparable pattern.V
`After the pattern hasbeen constructedI prei The pattern withv4 its accompanying core being formed as above described, I then proceed with the molding and casting operations in the following manner The pattern is secured to a'suitable follow-board, and an impression is taken therefrom in the sand of the copeand drag. A portion or" one of these impressions is shown in Fig. 3. The diminished portions E E F F leave impressions e e f f in the sand, which serve as prints 7 to designate the exact position of the core, and serve to support the same, which core vis then applied in such a manner that its smaller sides H H iit within the prints j' ff, while its enlargements G G occupy the other prints, e e. The core, being thus applied, is entirely self-sustainin g, and no anchors or props of any kind are required to support it. After the core has been placed in its proper position, which is the work of but a few minutes only, the two members of the ask are united and the metal poured in through suitable gates. When the metal has cooled sufficiently, so as to permit the separation of the drag and cope, the castings will be llocated as shown in Fig. 4, in which the pipe-elbows A B O D correspond exactly with the members A B C D of the original pattern.
\ It will be seen, by referring to-ths last illus tration,- that the core remains in the pipe-elbows, as shown by dotted lines, and also at the prints e e' f f j lIn the above-described molding operations the pattern has been alluded toas being made of an entire piece, and employed in connection with a follow-board; but it is evident 'that it maybe divided in half by a plane'passing through the axis of the elbows, in whichcase each part of said divided pattern should beattached to a match-plate and used therewith in the ordinary manner of using match plates.
Although describing this mode V`of molding and casting as employed for the production of four distinct elbows at a single operationI do not propose to confine myself to this exact number, as it is evidentthat the pattern may consist of only two or three elbows, which' elbows may have the represented quarter-bend or any other desired curvature.' Y
l `In the usual matta oftasusg ity ips custom.
these objections are overcome, and a perfect and reliable elbow is furnished at zt reduced price.
Claim. I elaixn as my invention- The inode of molding and. casting pipe-elbows by e self-supportin g core, when arranged and adapted to be operated substantially as herein described, and for the purpose set forth.
In testimony of which invention I hereunto set my hand.
Witnesses: GEORGE ROSS.
