UNITED STATES PATENT OFFICE:

GEORGE C. SETCHELL, OF NORVICH, CONNECTICUT, ASSIGNOR TO THE VILLIAM II. PAGE WOOD TYPE COMPANY, OF SAME PLACE.

DIE FOR FORMI'NG WOOD TYPE.

SPECIFICATION forming part of Letters Patent No. 402,863, dated May. 7, 1889.

Application filed December 5, 1888. Serial No. 292,735. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE C. SETOHELL, of Norwich, vin the county of New London and State Of Connecticut, have invented a new and useful Improvement in Dies for Forming Wood Type; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to dies for forming wood type by impression On the plan shown in an application filed by myself jointly with W. H. Page, December 5, 1888, Serial No. 292,719, and also an application filed by the said W. H. Page, Serial.NO.'292,7 34, and of same date. These dies are the counterpart of the types and have raised portions to press down the wood about one letter. In some parts Of the die the higher parts of the metal are necessarily thin, and these parts are therefore liable, as I have found, to bend in working, and thus ruin the work and the die. I have found by experiment that this may be remedied, without injury to the type produced, by reducing the height of these thin portions of the die below the surface Of the other parts of the die, and in this my invention consists.

It is illustrated in the accompanying drawings, in which- Figure l represents a perspective view of a die for the letter X. Fig. 2 shows a section on line :c of Fig. l. Fig. Sshows a perspective View of the die used in forming the type of M. Fig. 4 is a section of Fig. 3 On line Q/ y.

In Fig. l the portions o, indicate the parts of the die raised to give the full depth of the impression in the type. The parts Z7 (shown in the hatched lines) are the sunken parts. The lines l and points 2 indicate the division between the extremities of the letter. The lines indicate thin raised portions of the die, which make by impression a line of division, and these are lower, as shown in Fig. 2, than the other raised portions.

In Fig. 3 the points Sof the raised portions CZ are also thin, and these, as shown in Fig. 4, are beveled down thinnest at the extremity. This reduction of the thinnest portions gives at the same time lsufficient indentations in the wood of the type tO secure perfect lines in printing, and leaves a type better suited to cleaning.

A die for forming wood type by impression, having the thinnest portions of its raised parts reduced in height below thelevel of the other raised portions, substantially as described.

In testimony whereof I have signed my name to this specification in the presence Of two subscribing witnesses.

GEORGE C. SETCHELL.
