FLASK FOR CAR-WH EELS.
SPECIFICATION forming part of Letters Patent No. 393,615, dated November 27, 1888.
Application filed December 15, 1887. Serial No. 257,983.
State of Pennsylvania, have invented an Im- 'plan view of-the drag flask shown in Fig. 1;
Fig. 3 a longitudinal sectional elevation of a mold-containing flask embodying a modified form of my invention; and Fig. 4L a bottom plan view of the mold shown in Fig. 3.
In the drawings, A is a flask containing that part of the mold which is commonly' called the cope; B a flask containing that part of the mold which is commonly called the drag5 and C a cast iron ring called a chill57 Da cast car wheel and E the ribs or spokes thereof. Opposite these ribs or spokes of the cast wheel, and opposite those parts of the pattern, when it is in place in the sand in the flask, which form the parts of the mold in which the spokes of' the wheelare to be cast, the bottom of theflask B is provided with movable and adjustable sections F, which maybe thrust-inward to compress the sand in the mold between said sections and that part of the pattern which lies opposite thereto.
The movable sections F F may, in any given positions of adjustment, be held in place by springs G G, or by other suitable devices.
In Fig. 3, the movable sections F F are shown as hinged at H, in such manner that their opposite ends are free to be moved inwardly, and in said ligure they are shown as having been moved inwardly to effect the compression desired.
Itis well understood that in the manufacture of molds for casting car wheel, and for other purposes, it is frequently desirable that certain parts of the sand from which the mold (No model.)
is formed should be more eompactly rammed than other parts. To provide devices to accomplish this result is the object of my invention.
It will be understood that my invention is not conued to ila-sks for the manufacture of car wheels, as it may be embodied in flasks for the manufacture of molds for other articles, by so shaping and locating the movable sections as to adapt them to be moved and adjusted to compact or ram the sand at the points desired.
rl`he word adj ustable7 as used in this speci- -fication is employed to denote the fact that the movable sections F F are capable of being set at different positions relatively to the bottom of the flask after sand has been introduced into said flask for the purpose of forming the mold therein, and that said sections are capable of being held in their respective positions of adjustment by springs G G which are in contact with the outer surfaces of said sections and which follow and remain in contact with them in their` inward movement to said positions of adjustment.
The manner of operating the flasks shown in the drawings and above described, is as follows:-Sand is supplied to the flask B in sufficient quantity to form a moldand the pattern D is placed in upon, and in contact with, the sand contained in said flask. The movable sections F F are then by hand, or in any convenient manner, forced inwardly or upwardly, with the result that the sand lying between said movable sections and that partl or those parts of the pattern to which the said sections are opposite, is compressed and made more solid. The strength and shape of thc springs G G are such as to cause said springs to follow said movable sections F F in their movements just described and to retain said sections in their new positions to which as above described they have been moved.
In use, the drag flask shown in the drawings may be supported upon legs, or it may rest upon a table having proper openings therein opposite to the sections F F, through which the operator may have access to and may move said sections.
Having thus described -my invention, I elaimz l. A flask for car wheel or other molds, pro- ICO vided, in its bottom, with movable and adjust- In testimony whereofI have hereunto signed able sections, substantially as set forth. my naine this 26th day of November, A. D. to

vided, iu its bottom, and at suoli points there- 5 in as it is desired to, in the formation of asand JOSEPH J CARR' mold, compress the sand against the pattern, In presence ofwith movable and adjustable sections, sub- J BONSALL TAYLOR,
stantially as set forth. F. NORMAN DIXON.
