UNITED STATES PATENT OFFICE,
, JOSEPH B, JOHNSON, OF LYNN, MASSACHUSETTS, ASSIGNOR TO SWAIN FULLER 85 00., OF SAME PLACE.
IMPROVEMENT IN PATTERNS FOR CASTING DIES.
Specification forming part of Letters Patent No. 15] ,984, dated June 16, 1874; application filed v April 2'2, 1874.
To all whom it may concern:
Be it known that I, JOSEPH B. J OHNsON, of Lynn, of the county of Essex and State of Massachusets, have invented a new and useful Improvement in the Manufacture of Patterns for Casting Molds for Shaping Shoe-Soles; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which Figure l is a top view, Fig. 2 a side elevation, Fig. 3 a longitudinal section, and Fig. 4 a transverse section, of one of the said patterns.
In constructing the said pattern, I make use of an open box, A, having an internal periphery to fit to the periphery of the pattern-sole, whose external surface or tread is to be copied. The sole, with or without an upper at taehed, is to be introduced into the mouth of the box, so as to fill such, and constitute, as itwere, a cover thereto. Next, the box, which, previous to the introduction of the sole, is to be open both at top and bottom, is to be filled with a mass, B, of plaster-of-paris mixed with After the plaster may have set, a bot tom, a, is to be fixed to the box, and the shoe or sole should be removed from the box and bed of plaster. An impression or counter-form of the sole will thus be produced in the plaster. Next, the upper edge of the box should be cut down to the plaster all around, and in prolongation laterally of the molded surface circumscribed by it. The whole, after having been covered with black varnish, will eonstitute a pattern for molding in sand the matrix for casting in metal a die or mold for shaping by means of a press-the treads of other soles in correspondence with that Of the patternsole.
In order that the plaster when set may not drop out of the box, the inner surface of the latter may be provided with one or more grooves, or with studs or nails driven into it. The plaster, being cast in or around such, will thereby be kept in place; or, if preferable, the interior of the box may be tapering, or larger at bottom than at top.
I claim- As a new manufacture, a shoe-sole die-pattern, substantially as described, consisting of an open box, A, and a filling of plaster or eenient, 13, arranged in the said box, and molded to a sole, and provided with a bottom, a, fixed to the box, and having the edge of the box next the molded surface of the plaster formed in continuation thereof, all being essentially as specified.
JOSEPH B. JOHNsON.
