IMPROVEMENT IN CREASING DEVICES FOR TRACES, &c.

Specification forming part oi' Letters Patent No. 129,123, dated July 16, 1872.

To all whom it may concern Be it known that I, HOWARD S. FoUsT, of Wilmot, in the county of Stark and State of Ohio, have invented an Improved Oreasing Instrument for harness-traces and straps of leather; and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawing making part of this specification- Figure l being a top view ot' the die, showing one form of molding or creasing; Fig. 2, a side view of the creasing-tool, shaped to go with the die 5 Fig. 3, a cross-section of the die and of a harness-trace being creased therein, and a front View of the creasing-tool in position for operation in the die; Fig. 4, a crosssection of a finished trace creased in the die.

Like letters designate corresponding parts in all of the figures.

The die A is made from wood or other suitable material, and has a longitudinal groove, a, therein, of the form to produce the creasing' or shaping of the trace or other strap placed therein. It is of suflicient length to contain so much ofthe trace or strap as is required to be operated on at once, and need not be any longer. The creasing-tool B has a form of shaping end b to be the counterpart of the cross-section of the die A, as indicated in Fig. 3, and it is of proper lengthand size to hold in the hand. The molded end b also is rounded in side view, as shown, so that it will bear tangentially in whatever position held approximating to the vertical, thereby requiring no particular accuracy in holding. Its whole width is just sulcient to fit and run closely between the sides of the molding-groove in the die A, which serve as guides for that purpose, being high enough to keep the tool in place when containing a trace or strap, O, as

thick as ever required to be acted on, as vindicated in Fig. 3.

To use the instrument a portion of the trace or strap to be creased is laid in the die A,and the end of the creasing-tool B is moved forward and backward laterally over it repeatedly with suicient pressure to crease or shape the same permanently 5 then another portion of the trace or strap is drawn along into the die and treated as before till the whole is completed.

The advantages of this device for creasing or shaping leather are not merely its simplicity and cheapness, but the work done by it is much more perfect and permanent than when done between rollers, since the repeated rubbin gs forward and backward with pressure produce much more thorough work than by simple compressiononce applied; and the leather being held in a straight position, while undergoing the operation, is thereby left in better shape than when supported only at `the line of contact between rollers.

Fig. 4 shows a trace stuffed in its grooved surface ush with the remainder of the surface on that side, strip, d, of leather.

The operation of the tool B over the die A may be effected by machinery.

What I claim as my invention, and desire to secure by Letters Patent, is v The combination ofthe die A and creasingtool B, constructed and operating substantially as and for the purpose herein specified.

Specification signed by me this 8th day of February, 1872.
