FRANCIS W. GIBBY AND LE WIS Gr. GOLDSMITH, OF BOSTON, MASS.
IMPROVEMENT IN MOLDS FOR PILLARS.
Specification forming part of Letters Patent No. 1 79,186, dated June 27, 1876; application filed March 27, 1876.
To all whom it may concern:
Be it known that we, FRANCIS W. GIBBYand LEWIs G. GOLDSMITH, both of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Flask for Molding Iron Columns, &c.; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of'our invention consists in the construction and arrangement of the different portions of the flask, below described in detail. By means of this flask heavy iron columns may be molded and cast without a pattern, thus saving a large expense, as in most cases a pattern manufactured for a column is of no use whatever, after being used for the one column for which it is made.
In the accompanying drawings similar letters of reference indicate corresponding parts in the different figures.
WVe will proceed to describe the different figures and the method of operating our invention.
Figure 1 is a view of the mold-board. a is the mold-board, provided with strips a. b is a board set or slid into the mold-board a, upon which are pinned the moldings for a side of the pillar, or, if the sides are all alike, a single pattern for all sides. The mold-board a, provided with the moldings on the part 12, takes the place of the large pattern usually built. All sides of the pillar are molded upon it.
Fig. 2 illustrates the process of molding one side. Upon the mold-board a, fitting over the strips (1. by means of grooves c, is the upset c, and above it is the drag or nowel d. The sand is placed in as it stands in Fig. 2, and it is filled and rammed up, a board placed upon it, and it is reversed, leaving the drag d on the under side, when the mold-board a and upset c are removed. The sand remains in the drag d, molded into shape for one side of the pillar, and the upset c is removed permanently, as no further use of it is required in this operation.
In Fig. 3, the second side is molded. The mold-board amay be altered, if necessary, but
it is usually in the same condition as when used for the first side, in Fig. 2. The plate (or back)fand the ends 9 having been removed from the cheek c, it is placed upon the moldboard and ram med up to form the second side. The ends 9 are attached to, and detached from, the projections 6 upon the cheek c. The platefis replaced upon the cheek c after the ramming-up process, the cheek and moldboard are placed the other side up, the moldboard removed, and the second side is formed. The third side is formed by means of another check, in an exactly similar way.
It may be well to state that each cheek need not be provided with two sides, as a side may be transferred from one to the other.
To form the fourth and last side, place the cope h upon the mold-board, as in Fig. 4, ram it up, reverse it, and the fourth side is molded.
Fig. 5 is a viewof the flask complete, and Fig. 6 is a transverse section of the same. The drag cl, containing the mold of the first side, is at the bottom, the cheeks e, (the sides having been, of course, removed,) containing upon the plates f of said cheeks molds of the second and third sides, are set up on the drag d, and bolted tightly together by means of the flanges g. (The ends 9 are, of course, replaced.) The cope h containing the mold of the fourth side is on top, when the mold is ready to receive metal. The core may be placed in the flask at any convenient time before its completion.
If a portion or the whole of two sides of the column are to be plain, then the mold may be easily scraped off at the proper places.
Thus it will be seen that no pattern is necessary, all-that is needed being the moldings for one side, which may be attached to the board I) and easily removed. The workman has every opportunity to finish his mold, it being easily got at, while, by the old process, it is an awkward and often an impossible task to reach down and finish it. Ninc-tenths of the facing and half the labor are saved by this flask. This flask may be used upon nearly all square castings, such as columns and posts, doing perfect work. Much iron can be saved by coring out a base, panel, &c., by putting the core in first, and the sides afterward. The
flask is adapted for almost any sized column by loweringthe bed of the mold by theaid of the upset.
Of course it is understood that the flask must be properly secured before the metal is poured in.
Having thus fully described. our invention,
what we claim, and desire to secure by Letters Patent, is-.
The flask consisting of the drag d, cope h,
