Parent* rtree,

LOUISVILLE, KENTUCKY, ASSIGNOR TO HENRY SULZER, OF SAME PLACE.

CASING FOR CASTlNG STOVE-DOOR CATCHES.

SPECIFICATION forming part of Letters Patent No. 321,549, dated July 7, 1885.

Application filed January G, 1885. (No model.)

To all whom t may concern.-

Be it known that l, Unsinn Vn'rrnn, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Casting Catches for Stove-Doors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a box or casing for casting catches upon stovedoors, which box or casing is to be used in connection with the patterns of a stove door, (for forming molds for stove-doors to be cast with catches,) and left in the mold when the pattern is withdrawn from the sand, by which means the casting will not adhere to the casing, and a perfectly smooth casting will be secured.

With these ends in view the invention consists in a peculiar construction o' box or casing of sheet metal, and in details of construe tion hereinafter fully described, and pointed out in the claim.

In the drawings, Figure 1 is a perspective view of a box or casing constructed in accordance with my invention. Fig. 2 is a vertical section of the same. Fig. 3 is an end view. Fig. 4 is a side view of a modification which is of the same construction as that shown in Fig. 2, excepting that a portion of the sides are removed or cut ofi'.

In the accompanying drawings, in which like letters of reference indicate correspondingparts in all the figures, A represents my improved box or casing, which is preferably constructed of sheetiron, for the reason that it has been found that the casting will not adhere to the sides of the same, thus allowing the box or casing to be easily separated.

The said box or casing A consists of the sides a, arranged a distance apart suitable to the casting of a catch of the desired thickness. The said sidesa' are of a greater width at their lower than at their upper ends,as shown. At or near the lower ends of the sides a,upon one side, c', thereol', are formed recesses or notches b, which approximate an inverted L in form, or nearly so. Closing the space between the upper ends of the sides aand the space between said sides; at the side a thereof', is a strip of metal, e. The said strip of metal e may be formed integral with one of thesides and bent and brazed to the other, or it may be of a separate strip secured bctween. The said strip is bent near its lower end inwardly, and then downwardly to conform to the shape of the invcrted-L-shape recesses or notches b, thus forming within the casing au inwardly-extending L -shapg P110. jection, f, which, when the catch is cast, forms an inverted-L-shapcd seat upon the same. The shell or casing is placed upon the pattern, and the drag portion of the flask rammed up with sand in the usual manner, when said. portion of the lask is inverted` and the upper half or cope adjusted in position and rammed up. Vhen the cope is lifted from the drag and the pattern removed from the same, the shell or casing will remaiirin the cope. The parts of the iiask are then united and molten metal introduced, and the easting is removed and separated from the shell or casing. By thus casting the catch in a sheet-metal shell or casing a clear and smooth casting is secured.

It will be understood that my invention is susceptible of modifications. The form ofthe notches in the sides remains the same, but the general form of the sides is varied, as seen in Fig. 4.

The above-described box creasing is simple in its construction, and, as before mentioned, by the employment of sheet-iron the box and catch do not adhere, and may be readily and easily separated.

I am aware that casting against metal to chill and smooth the casting is old, and this I do not claim; but my invention consists, substantially, in the device which I have constructed for use in casting catches, which is capable of partially shaping and smoothing the catch, and also of being separated from the pattern and the casting.

) l claim as my invention and desire t-o sef'cure by Letters Patent-- The herein-described casing for casting catches upon stove-doors and the like, construoted of' sheet metal, having opposite oorresponding sides with the angular notches or recesses in opposite corners thereof, and n GASPAR VETTER' 5 strip of metal uniting said sides and bent up Vitnesses:

to form an angular inwardly-prometng sent., HARRY STUGKY,

substantially as shown and described. I FRED E. HEINIG.

In testimony whereof I afx my signature in presence of two Witnesses.
