JAMES MGDERMOTT, OF LOUISVILLE, KENTUCKY.
MOLD FoR DOG-IRONS.
SPECIFICATION forming part of Letters Patent No. 225,712, dated March 23, 1880.
Application filed December 24, 1879.
To all whom it may concern:
Be it known that 1, JAMES MODERMOTT, of the city of Louisville, in the county of J efferson and State of Kentucky, have invented a certain new and useful Improvement in Molds for Making Dog-Irons; and I do hereby de" clare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, forming part of this specification, and to the letters of reference marked thereon.
Figure 1 is a perspective view of the flask when closed up ready for use. Fig. 2 is a perspective view of the device, showing the interior arrangement of the molds therein.
This my invention relates to a certain new and useful improvement in metallic flasks and molds combined, for the purpose of making dog-irons, consisting, first, in a flat metal plate of the required size and thickness to answer as a base or follow plate for the flask, and also to receive the depression in the center that forms a part of the molds, this part of which is provided with all necessary forms or figures carved in the bottom as ornaments for the front or face of the article, while the face of the plate is made perfectly smooth and straight; and in order to complete the mold for the shank and back leg of the article, a plate of similar dimensions is made in two pieces to cover it, and is hinged to the sides of the lower plate, so that when closed down the faces will fit closely to prevent the melted metal from escaping in casting. To the inner edges of these last-named plates upright pieces are either east or'seenred at right angles, so that when the hinged parts are closed down the uprights will close flat together, forming a joint sufficiently perfect to hold melted metal when clamped together in the usual manner. The inner faces of these upright parts are made of the form and size of the shank and back leg, with the upper end of the mold left open to pour in the metal in casting.
This my invention will be more fully illustrated in detail in the drawings, in which A represents the base-plate or follow-board of the flask, which is made of metal of the required size and thickness to admit of a recess on the face deep enough to form a mold for the front part of the dog-iron.
B is the recess or mold, the bottom of which is carved or cut out so as to form the negative of such pictures or figures as may be required to ornament the front of the article.
D D are metal plates-hinged to the sides of the base-plate A, to answer as a cope for the mold below, and must therefore fit neatly when closed down, to prevent the escape of metal in casting. j
E E are the upright parts, cast on theinner edges of the last-named plates, and are somewhat in the form of the shank and leg of the iron. These upright pieces, when brought together, fit closely on the faces, which are recessed or cut out to form molds F F corre' sponding with the size and form of the shank and back leg of the iron when closed up, with the upper end left open to pour in the metal in casting.
The difierent parts of the flask containing the molds, when closed up ready for use, are firmly secured by clamps or otherwise in casting, and when the metal appears sufficiently set the clamps are knocked off and the casting turned out without further loss of time, which is a great saving of time and labor over the old process of molding in sand.
I am aware that the face or front part of dog irons has been cast in an open metal mold, leaving the back rough and imperfect, and requires the shank to be cast in it at another time, which makes the connection very weak and imperfect for want of union between the melted and unmelted metals; but so far as I am aware no dog-irons or parts of dogirons have been cast in coped or inclosed metal mold without a sand surface.
Having thus fully described the nature and object of this my invention, what I claim as new, and desire to secure by Letters Patent, in metal flasks and molds for making dogirons is The hinged cope-plates D D, combined with the upright forms E E, having recesses or molds F F on the inner faces, as above described, in combination with the base-plate A, having recess or mold B, substantially as herein described, and for the purpose set forth.
JAMES MCDERMOTT.
