WILLIAM TAYLOR, OF PEEKSKILL, NEW YORK, ASSIGN OR TO HIMSELF AND GEORGE W. ROBERTSON,
OF SAME PLACE.
MODE OF REPAIRING 'METALLIC PATTERNS.
SPECIFICATION forming part of Letters Patent No. 229,064, dated June 22, 1880. Application filed May 10, 1880. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM TAYLOR, of Peekskill, in the county of Westchester and State of New York, have invented a new and useful Improvement in Modes of RepairingMetallic Patterns for Castings, of which the following is a specification.
Cast-iron patterns used in making castings,
especially when thin or rendered delicate by ornamentation, are liable to be broken by careless handling or in freeing them from the molding-sand by blows of the hammer or otherwise.
Heretofore the difficulty in inending these patterns when broken has been so great that it has been cheaper to replace them with new ones.
The present invention relates to a method or process by which metallic pat-terns, when broken, can be economically and practically repaired; and it consists in forming amatrix in a mold from the pieces of the original pattern, removing the pieces from the mold, preparing them with holes and channels along the fractured edges, placing the prepared pieces in the mold, and uniting them by running easily-fused metal into the holes and channels, substantially as hereinafter more fully set forth.
The invention is illustrated by the accompanying drawings, in which Figure l is aplan view of a broken pattern. Fig. 2 is a plan view of the same after it has been repaired by this invention. Fig. 3 is a sectional view along the lines as 00 and m w of Fig. 2, showing the shape of the holes I) b and the channel 0 0,- and Fig. 4 is a sectional view along the line 3 3 of Fig. 2, showing the shape of the main channel 0.
In these drawings, A represents a pattern of cast-iron or other cast metal broken into two pieces, a and a, the line of fracture being indicated by f f of Fig. 1.
The broken pattern is repaired in accordance with this invention by uniting the pieces a and a in the following manner: A matrix is formed in the usual wayin a mold by using the pieces a and a as patterns, their fractured edges being brought close together, as shown in Fig. 1, during the molding, so as to produce a matrix as near as practicable like one formed from the pattern A before it was broken. When the pieces are taken from the mold any imperfections in the matrix caused by the sand will be a channel or opening between them for the flow of the melted binding metal. This channel is designated in the drawings by 0. Holes 2) b are bored near the edge of each piece, and are connected with the edges by channels 0 0, formed by filing or grinding or cutting out the metal with any suitable tool. These holes and channels should be of size and number to permit a sufficient quantity of the molten metal to unite with each of the pieces to firmly secure them together, and the holes are preferably to be countersunk on both sides of the pieces, and the walls of the channels 0 0, as well as of the main channel 0, are to be inclined or dovetailed, substantially as shown in Fig. 4 of the drawings, which construction will have the effect to firmly lock the pieces together in all directions.
It may be observed that it will make no material difference to what extent the edges of the pieces bordering the line of fracture are ground away, inasmuch as the configuration or ornamentation of the parts thus removed is already formed in the matrix and will be reproduced in the repaired pattern by the melted metal.
After the pieces have been prepared as above described they are replaced in the matrix of the mold, which they will fill, with the exception of the channel or space between the pieces and the small channels 0 o and the holes I) I), all of which have been made since the matrix was formed by cutting away the metal of the pieces. The mold is then closed, and melted metal poured in at a gate arranged to connect with the space or channel between the pieces a, and a, whereby this space, the channels 0 c, and the holes I) b are filled with the melted metal, which, upon cooling, firmly unites the different parts or pieces. Preferably an easily-fusible metal or alloy, which will contract that when they are replaced in the mold there but slightly in cooling and is sufficiently soft to permit the surface of the pattern to be finished up or smoothed off, is used for the uniting metal.
Patterns broken into several pieces may be repaired in this manner, and whenever, as is frequently the case, some of the pieces are too small to be practically provided with holes and channels, and thereby united with the others, such pieces, after being used to form the matrix, may be discarded and their places supplied with new metal in the operation of uniting the remaining pieces. This construction is illustrated in Fig. 5 of the drawings, in which the small pieces d d, broken out of the central part with the new metal, which is run into the mold through properly-located gates. In this case, as in that heretofore described, it will make no difference to what extent the fractured edges of the main piece are cut or ground away, as their impression has been transferred to the matrix and will be reproduced in the part or parts formed by the running in of the new metal.
What is claimed as new is- The hereinbefore-described mode of repairing metallic patterns, which consists in molding a matrix from the pieces of the original pattern, removing the pieces from the mold and preparing them with holes and channels along their edges, replacing the prepared pieces in the mold, and uniting them by running easily-fused metal between the pieces to fill the holes and channels, substantially as set forth.
WILLIAM TAYLOR.
