IMPROVEMENT IN THE METHOD 0F MOLDING KETTLES WITH SPOUTS.

Specification forming part of Letters Patent No. @,471, dated October 28, 18:31.

To ail whom it may concern:

Be it known that I, WEBSTER H. Finish, of

-Daytom in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Molding Tea-Kettles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification.

Figure l is a perspective view ofthe pattern for molding the tea-kettle; Fig. 2, a central vertical section of the same 5 Fig. 3, a sectional view ofthe lower and upper parts of the pattern for the body, the lid removed and parts separated; Fig. 4, a section of the eorcbox for the spout, the parts separated.

In constructing my pattern for molding the body of the tea-kettle, I divide it horizontally in the usual manner*viz., at the swell or upper portion of the body, placing the spout at the swell, instead of inserting it near the bottom. By this forni I am the better prepared y to introduce my mod e of forming the moldingpattern.

rIhe nature of my invention and improvement consists in providing the upper part of the pattern of thebody of the kettle with two projections, one placed on the under side of the spout portion of said pattern, to prevent sand entering the spout when forming the green core of the body, and the other proj eetion on the upper side of the spout, for forming a print in the sand to receive a projection of a dry-sand core, (formed in a core-bony) by the use of which in connection the said drysand spout-core can be inserted in the drag portion of the mold after the removal of the upper part of the pattern, but before the removal of the lower part of the pattern, and be held firmly in its required position, by which means the lowerpattcrn is made to adj ust the spoutcore, and greater truth secured in setting the spout-core, and fewer defective casts result; also, in the facility of molding the kettle and dispensing with an anchor Aor spi-ig required in other modes to keep the spouteore in its place, as the print in the mold formed by H on the upper side of the spout of the pattern forms a receptacle or indent for the square projeetingportion I ofthe dryesand spout-core.

rIhe following is a description ofthe pattern:

Ii is the lid; L L, the-ears for the handle; A,

the lower portion of the pattern ofthe body, with a rim, E, in the usual manner for making a joint. To this the under side, C, ofthe spout is attached. B, the upper portion of the body,havingthe remaining side D ofthe spout, which is provided on its under side with a solid projection, G, iitting the hollow of the spout, and preventing the sand used in forming the green core for the body of the kettle entering, thus preserying the hollow in the mold for the after insertion of the spoutcore, the upper part, or H of Gthat above the dotted lineforming a projection and print for the recepy suitably-formed follow or molding board, sur

round it with the cope, a part of the flask, and fill the space with sand between the outslde of A and the sides of the cope. Then reverse the cope and pattern still remaining and make a parting at E, the upper edge of A, in the usual manner. Now replace B (the upper part of the pattern) 0n A, surround it with the drag or other portion of the flask, and iill the inside of A and B with sand, make apa-rt- `ing across the inside of B at F, the top of the pattern thus forming the green core for the body of the kettle, but divested of the spout, fill up outside of B and above F level with the top of the flask, the space between the pattern and the sides of the flask, the parting at F preventing the green core of the body joining the drag portion of the .mold outside or above B, and the projection H on the outside ofthe spout, attached to B, forming a print or indentation in the sand for the reception of the projection I ofthe dry-sand core made in the core-box G I. Lift the drag from the cope, turn it up, and remove B of the pattern, insert the dry-sand spout-coreG I, placing I in the print made in the sand of the drag by H, return the cope containing A to its rst position, placing it on the drag carefully, by

which the eore for the spout will be adjusted. Now lift ofi" the eope7 but leaving the pattern A on the drag, which is afterward removed, make the proper gate in the cope, 'replace it on the drag, and it is ready for casting.

Having thus described my method of molding tea-kettles, I do not claim any peeuliarity either in dividing the pattern or using agreensand eore; but

That I do claim as my invention, and desire to secure by Letters Patent, is-

Providing' the pattern B with two projecting or solid pieces, one, G, on the underside ofthe spout portion D, to prevent sand entering the spout when forming the green core of the body, and the other, H, on the upper side of the spout D, for forming a print in the sand to receive the projection I of a dry-sand core, G I, by the use of which in Connection the said dry-sand spout-core G I can be inserted in the drag portion of the mold after the removal of B, but before the removal of A, and` be held firmly in its required position, by which means the pattern A is made to adjust the spouteore, and greater truth secured in setting the spout-eore, and fewer defective casts result, in the manner set forth substantially in this specification and accompanying drawings.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
