UNITED STATES PATENT OFFICE,
ROBERT S. CARR, OF HAMILTON, OHIO, ASSIGNOR TO F. & L. KAHN & BROTHERS, OF SAME PLACE.
COOKING-STOVE.
SPECIFICATION forming part of Letters Patent No. 415,938, dated November 26, 1889. Application filed February 25, 1889i Serial No. 301,153 (No model.)
To all whom it may concern.-
Be it known that I, ROBERT S. CARR, of Hamilton, Butlercounty, Ohio, have invented certain new and useful Improvements in Cooking Stoves and Ranges, of which the following is a specification.
This invention relates to an improvement in cooking-stoves; and the object of the improvement is to fit an integral portion of the stove structure to serve as a knife-sharpener. j
The improvement Will be readily understood from the following description, taken in connection with the accompanying drawings, in which' Figure l is a perspective View of a cooking-stove exemplifying my improvement, and Fig. 2 is a vertical transverse section of the edge portion of the top plate of the stove.
In the drawings, A indicates the stove; B, one of the upper edge corners of the stove;
1, the top plate of the stove, and D that portion of the metal lying at the corner 13. The edge corner B is-t-o be formed of chilled castiron, and the faces which join to form the corner are to be ground to bring the corner to a keen edge. The portion of the corner which is chilled should be not less than six inches longin other words, whatever portion of the' stove structure is chosen for the reception of the chilled corner, the chilling should extend along said corner a distance, preferably, of not less than six inches. A knife-blade drawn lengthwise across the chilled corner will become sharpened. The point chosen for the location of the knifesharpener may be at any convenient place about the stove structure.
To construct the improvement the procedure is recommended as follows: Construct the patterns for the stove parts as usual. Then select the particular point at which the chilled corner is desired. Taking the pattern corre sponding with the particular part selected, permanently attach a piece of wood to the pattern so as to completely cover the corner which is to be chilled. Before this piece of wood is attached to the pattern make an iron casting of it and dress the interior of it nicely. Mold the pattern in the usual manner. Upon the withdrawal of the pattern the attached piece of wood will have left its print in the sand. The extra casting which has been made constitutes the chill, and this chill will fit within the mold-cavity formed by the added strip of Wood. The oasting'is now poured, as usual. Most of the casting will of course be formed in the sand mold,as usual; but a portion of the metal going to form the selected corner part will be formed in contact with the chill which has been inserted in the mold, and this corner portion will become formed of chilled cast-iron. The casting having been made, the faces which join at the chill corner are to be accurately and nicely ground to bring the corner to a keen and perfect edge. This is of the highest importance. The grinding may be done upon an emery-wheel or a grindstone. It is preferable, in doing this grinding, that the grinding-marks be made transverse to the corner-in other words, the corner should be presented to the wheel or stone transversely, so that any attrition-marks produced will be transverse to the corner edge instead of parallel to the corner edge. It is furthermore highly desirable, when doing this transverse grinding, that the wheel or stone run in such direction as to carry the metal from the corner'instead of toward it thus in Fig. 2 let E represent the Wheel or stone, and arrow F the direction of its rotary motion. Vere the wheel or stone run in the other direction, or were it run lengthwise with reference to the corner edge, a somewhat fragile andcrumbly edge would be produced, which would not fulfill, the conditions of a durable knife-sharpener.. By proceeding in the manner pointed out a keen, substantial, and durable edge is produced. The angle formed by the two faces which join at the chill corner should, preferably, not be an'acu te one.
I claim as my invention- A stove part formed of cast-iron and having a keenlyground chilled corner edge, sub- 9 stantially as and for the purpose set forth.
