WOOD-ORNAMENTING DIES.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed March 27,1906. Serial No. 308,349.

To (LU w/wm it may concern:

Be it known that I, ELMER C. DITTMAR, a citizen of the United States, residing at Villiamsport, in the county of Lycoming, State of Pennsylvania, have invented certain new and useful Improvements in l/Vood-Ornamenting Dies, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to ornamenting-dies, and particularly to a construction and arrangement for ornamenting the entire periphery of an article.

The invention has for an object to prevent the formation of a fin or rib at the meeting points of the dies used, which is the ordinary result from such impression, and to provide cooperating dies each having an impressingsurface and also a non-impressing surface or clearance porti'on at the meeting edges of the dies, whereby the first impression with the dies ornaments a portion of the periphery of the article, which is then turned to bring the previously-ornamented portion opposite the non-impressing surface at the point of jointme and the unornamented face opposite the impressing-surface.

Other and further objects and advantages of the invention will be hereinafter fully set forth and the novel features thereof defined by, the appended claims.

In the drawings, Figures 1 and 2 are sectional perspective views showing an arrangement of four dies in operative relation to the work at the first and second stage of the impression thereon. Figs. 3 and 4 are similar views of two dies adapted to accomplish the same result; and Fig. 5 is a reduced vertical section on line 5 5, Fig. 1.

Like numerals of reference designate similar parts throughout the several views of the drawmgs.

In the form of the invention shown in Figs. 1 and 2 the dies used to ornament the article, which may be of wood or any other desirable material, comprise four in number, each of similar construction and adapted to simultaneously approach a common center to engage and ornament or impress the surface of the article placed between the same. The numeral 1 indicates the dies, which extend longitudinally for the length of the impressed or ornamented portion of the article, as shown in Fig. 5, each being provided with suitable lugs 2 at their ends for attachment to proper operating mechanism. Intermediate of the opposite ends of each die, and preferably centrally thereof, an impressingface 3 is provided, carrying any suitab e form of ornament, while at the end of each of the dies a clearance portion 4, or non-impressing surface, is provided. This portion 4 may be cut away, so as to only sli htly con,- tact with the material of the artic e, the essential feature, however, being not to produce a fin or rib at the meeting-point of the edges, as it is difficult to secure a clear impression, or to continue the compressing-surface to this point, owing to the necessary spacing which must be allowed in the movement and travel of the dies.

In the form shown in Figs. 1 and 2 a wooden article 5 of longitudinal character is shown as disposed within the dies, and the first impression is produced at the portion 6 thereof. The dies are then opened and the article turned to a proper extent-for instance, forty-five degrees to its original position, as shown by the arrow in each of the fi ures thus bringing the non-impressed portion 7 of the article opposite the impression-face of the dies, while the previously impressed faces are disposed opposite the clearancefaces or non-impressing faces at the meeting edges of the dies, thus completing the ornamentation of the surfaces without the formation of any ribs or line of demarcation at this point.

The same result may be secured by a less number of diesfor instance, as shown in Figs. 3 and 4, where two dies 8 are shown, each being provided with ornamenting or impressing faces 9 and with non-impressing portions 10 at their meeting edges, so that the article 11 introduced therein is first impressed upon the opposite faces 12, leaving plain the unimpressed faces 13, which are next engaged by rotating the work ninety degrees to its former position, so as to bring the portions 12 opposite the clearance-spaces 10 in each die and the portions 13 opposite the impressing-faces 9 thereon, thus com pleting the operation.

From the foregoing it is believed that the construction and operation of the dies rela tive to the work embraced therein will be clearly understood, and it will be seen that the fin or rib ordinarily produced when an article is ornamented by a single pressure is avoided by subjecting the work to a plurality of impressions, preferably two, as one compression is completed .at the first impression and the remaining portion at the second impression without injury to the previouslyimpressed face.

The invention is particularly adapted for ornamenting round or irregular columns formed of wood by impressing upon the periphery thereof the design to be produced upon the completed article. These impressions may be secured by moving the Work relative to one set of dies or by disposing an other set of dies relative to the section of the work to be ornamented.

It will be apparent that the opposing dies are provided with intermediate portions which actually engage and press the work and with other outlying clearance portions facing the Work, but recessed from the die portions sufiiciently to leave the work uncompressed, together with means for limiting the degree of pressure upon the work, such as the contacting faces upon the dies.

Having now described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. A plurality of opposing dies having intermediate portions which actually engage and press the work and other outlying clearance portions facing the work but recessed from the die portions sufliciently to leave the work uncompressed, and means for limiting the degree of pressure upon the work.

2. A plurality of opposing dies having intermediate portions which actually engage and press the work and other outlying clearance portions facing the work but recessed from the die portions sufi iciently to leave the work uncompressed, and contacting faces upon said dies to limit the degree of pressure upon the work.

37 An ornamenting-die provided intermediate of its ends with an impressing-surface to engage and press the Work and with outlying non-compressing portions adapted to face the Work and recessed from said surface sufiiciently to leave the work uncompressed thereby.

In testimony whereof I affix my signature in presence of two witnesses. v
