SAD-iRON MOLD.

SPECIFICATION forming part of Letters Patent No. 342,370, dated May 25, 1886. Application filed MarchfiU. 1886. Serial No. 197,148. (No model.)

To all whom it may concern:

Be it known that I, PLATT LYON, Jr., a citizen of the United States, residin g at J effersonville, in the county of Clark, State of Indiana, have invented certain new and useful Improvements in Sad-Iron Chills, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention. is to provide a chill or mold from which a sad-iron can be readily liberated after being cast therein, so as to surround the shanks of the handle-standards; and the improvement consists in furnishing the cope of such a mold with a cover or cap composed of three separate and distinct parts or sections. Of these members the two end sections are capable of being shifted longitudinall y off the mold,while the central member is arranged to be elevated bodilyand then shifted laterally, thus detaching the cap from the handle of the iron and permitting said iron to drop out of the cope as soon as the latter is separated from the drag, as hereinafter more fully described.

111 the annexed drawings, Figure 1 is a 1011- gitudinal section of achill or mold embodying my improvements, a sadiron being shown cast in the matrix of the cope, and the cap or cover of the same being closed. Fig. 2 is a plan of the closed mold or cover, the shape of the matrix being indicated by dotted lines, and the iron handle-standards being sectioned. Fig. 3 is a similar section, but showing said cover separated from the iron preparatory to liberating the latter from the chill. Fig. 4 is a plan of a modification of the invention. Fig.5 is an enlarged transverse section of one of the covers or caps.

A represents the drag of a metallic flask, mold, or chill, said drag being provided either with guides or dowel-pins or other suitable devices, B, to insure the proper application of the cope G, the latter being furnished with a matrix, D, in which the sad-iron iscast. E is a gate to admit the molten iron into said -matrix,which matrix passes completely through from the top to the bottom of the cope, and is covered by a cap composed of three sections or parts, F G G, the sections G G being con- 5 fined between guides HH and I I, so as to be readily shifted longitudinally off the mold after the buttons h h i i have been properly turned. The inner or opposing edges of the shiftable sections are notched, respectively, at g g, to pass about halfway around the standards of the handle, as more clearly seen in Fig. The central section, F, is notched on its edges, as at ff, to pass about half-way around the other sides of the handlestandards, and is held in place on the cope by buttons J or other convenient retaining devices.

K are knobs or handles for the sections F G G of the separable cap or cover.

L is the sad-iron, M the handle proper of the same, and N N the standards thereof, said standards being bowed away from each other, as at n n, or otherwise provided with a passage or passages that will permit lateral withdrawal of the central section, F. The extreme lower ends of these standards constitute shanks, which are notched, as seen at V V in Fig. 1, to allow the molten iron to anchor therein.

0 is a handle for the cope G.

The method of using the chill is as follows: The cope C is first seated upon the drag A in the usual manner, and the notched shanks of the standards N N of the handle are placed in the mold and retained therein by the cap or cover F G G, the notches of which ffg g fit snugly around said standards. The buttons 71., h, 'i, i, and J are then properly turned to hold the cover in place and prevent it being lifted by the expansion of the metal, after which act the molten iron is poured in at the gate E, thereby filling the matrix D, the handle being kept in an erect position by the molder, or otherwise. Consequently, the sad-iron L is securely cast to the standards N N of the handle M, the notches V V of the shanks preventing any detachment of the latter. After the metal has cooled snlficiently, the cover G is shifted toward the front of the mold, and the other cover, G, is slid in an opposite direction, thereby liberating said sections G G from the standards; but the central section, F, cannot now be shifted either longitudinally or laterally of the mold, but must be raised vertically, as seen in Fig-2. As soon, however, as this section has been elevated as high as the bowed portions n n of the standards, it is then free of the latter, and can be drawn out horizontally, either to the right or left, as may be most convenient. (See dotted lines in Fig. 4.) It is evident the handle is now entirely free of the cover or other retaining devices, and the very instant the cope is lifted off from the drag the sad-iron drops out of the matrix, and is ready for grinding as soon as the sprue is broken off of it. The cope is then remounted on the drag, a new handle inserted in the matrix, the sectional cover closed around the standards of said handle, and anothersadiron is cast and liberated in the manner just described.

The guide H (seen in Fig. 5) is undercut, to admit the beveled edge of the cover G, which expedient enables me to dispense with turn-buttons or other retaining devices.

In another modification (seen in Fig. 4) the undercut guides and buttons are both dispensed with, and a pair of swinging latches, P P, are employed for holding the covers G G in place, the free ends of said latches being hook-shaped, so as to engage under the heads of pins or screws p 1). Furthermore, in this 7 illustration the inner margins of said covers are provided with lugs R R, that hold the central section, F, firmly down upon the cope, said section being provided with a handle, S. T is a ledge or other stop that limits the insertion of this section and compels its notches to be in line with the notches of the contiguous end sections, G G.

U is a vertical flange or bearing at the end of the drag for the cope to abut against, and thereby dispense with the guiding devices B. (Seen in Fig. 2.)

Finally, no claim is made for the method of anchoring the notched handle-shanks into the body of the sad-iron, as this expedient is acknowledged to be old and well known to all molders of such irons.

I claim as my invention- 1. The combination, in a sad-iron chill, 0f the cope 0, having a matrix, D, a pair of notched shiftable covers, G g G g, and a notched central cover, Ff f, which latter is capable of being elevated bodily and then shifted laterally through suitable passages in the handle or handle-standards, substantially as described.

2. The combination, in a sad-iron chill, of the cope 0, having a matrix, D, gate E, threepart notched cover F f f G g, G guides H H I I, and retaining devices Pp P p, as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
