WITNESSESI UNITED STATES PATENT QEETGE GEORGE E. OHAMBERLIN, OF PROVIDENCE, RHODE ISLAND,'ASSIGNOR OF ONE-HALF HIS RIGHT TO BENJAMIN F. PABODIE, OF SAME PLACE.
IMPROVEMENT IN -FLASKS FOR MOLDINGS.
Specification forming part of Letters Patent No. 182,41 l, dated September 19, 1876 ap plioation led May 10, 1875.
To all whom it may concern:
Be it known that I, GEORGE E. CHAMBER- LIN, of Providence, county of Providence, State of Rhode Island, have invented a certain mImprovement in Flasks for Molding, of which the following is a specification:
My invention consists in making the main part or drag-box ot' the flask `in two or morev parts, and pivoting these parts together with a hinge at the bottom or end, so that this part of the ask can readilyswing open and relieve the casting from the sand or chills in which it has been formed by having the chill attached to the inner sides of the ask.
This device is especiallyT important where chills of intricate form are used to produce castings of uniform dimensions. The chills can be rigidly attached tothe sides ot' the flask, or may constitute a part of the same; and, although there may be projections on the chills to form recesses in the castings, they can readily be delivered by opening the drag after the cope has been removed, which could not be done with the ordinary solid draglask.
Figure l is a plan ot' my improved drag closed with the chills in position for use. Fig.
oted together at the bottom With rod R, so as.
to swing open,.carrying the chills c c to the position shown in Fig.2. aa, Sac., are studs projectingfrom the sides ot'the dragF, to which any desired form ofchills may be attached by means ot' set-screws s s, as shown, or by any othersuita ble device, permitting the chills to b e nicely adjusted and rigidly held in position, thereby securing uniformity in the castings, and faciii- `tating their removal from the iiask and chills.
I claim as my invention- The combination of a pivoted drag with chills, a chill being secured to each side ofthe drag, substantially' as shown, and for the purposes set forth. o
GEORGE E. CHAMBERLIN. Witnesses:
B. F. PABODIE, J. T. DOWNING.
