MPEIERS, PMOTO-LITHOGMPMER, WASHINGTON n C UNITED STATES PATENT OFFICE.
THOMAS MASON, OF NEW YORK, N. Y., ASSIGNOR TO DAVID WOLFE BRUCE, OF SAME PLACE.
IMPROVEMENT IN TVPE-MOLDS.
Specification formingpart of Letters Patent N 0. 187,880, dated F r y 27, 1877; application filed February 2, 1877.
To all whom it may concern:
Be it known that I, THOMAS MASON, of the city, county, and State of New York, have invented a new and Improved Type-(lasting Mold, of which the following is a specification:
Figure 1 is a side elevation, in section, on line as w in Fig. 2. Fig. 2 is a transverse sec tion on line 3 y in Fig. 1. Fig. 3 is an enlarged transverse section, showing the operation of the invention.
Similar letters of reference indicate corresponding parts.
My invention relates to improvements in the formation of the parts of a type-mold variously called jets, breaks, or slips, whereby a great saving of time and labor is effected, inasmuch as by my invention I am enabled to dispense with that branch of the type-founding trade technically known as the breaking off.
Referring to the drawing, A A are parts of a mold of ordinary construction, provided with the usual breaks B, between which the metal is injected into the mold. In these breaks angular or v-shaped recesses a are formed,
which, when the mold is closed together, are oppositely arranged in respect to each other, so that when metal is injected into the mold angular shoulders b, corresponding in form to the recesses a, are formed on each side of the break 0 of the type, so that as the mold is opened with the type or casting in it, the contrary action of the oppositely-arranged inclined sides of the recesses a produces sufficient strain to sever the break from the type which is retained by the shoulders of the mold.
The recesses in the breaks of the mold may be arc-shaped, or may have any other form which will effect the severing of the break.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent A type-mold provided with one or more oppositely-disposed angular projections or shoulders within its breaks for severing thejet from the type, as described.
' THOMAS MASON.
