Description

bers except that they have no type faces and serve merely to retain the type members in their properly spaced positions. When the type members are to be inserted in the opening in the die block the several sections of the type block are loosened and moved outwardlyslightly with relation to the center block so as to slightly increase the width of the annular space between the sections and the center block, thus permitting the easy insertion of the type members. However, the sections of the die block are retained in such positions that the type members will be supported thereby and may be easily located in the desired. arrangement. Vhen the type members have been fully assembled in the annular space the sections of the die block aremovedr inwardlyv by tightening down the locking devices of the. chase, or otherwise,y

to `clamp the type members between the sections andthe center block. rlhis tightening down of the dieblock sections not only clamps the type members between the sections and the center block but also firmly secures they center block to the die block.

f The type members 8 are` of the same radial width but they vary in thickness according to the letters which' they bear. The outer vertical edges'ofone of the thicker type memf bers will engage the circular wall ofthe opening in the die block along lines spaced apart a distance equal to the thickness of the type member and the central inner portiononly of such type member will engage the cylindrical center block. Thus a relatively thick type member requires that the annular space be-r tween the center block and the die block shall be of a radiall width. vslightly greater than the tru-e width of the type member. The vertical edges of a relatively thin type member will engage the curved wall of the opening along lines spaced but a short distance apart and will yhave an effective width less than the effective width of the thicker die blocks. Consequently, if the type members' are confined between circular metal surfaces the thicker type members will so limit the inward movement of the sections of th-e die block that the thinner type members will. not be firmly clamp-ed but will drop out of place when the die is lifted. To enable type members of all thicknesses to be firmly clamped in position l have interposed strips of compressible material between the type members and the die block, as shown at 10, and between the type members and the center block, as shown atll, so that when the die block sections are tightened down this material. will yield and accom-l modate itself to the surfaces of the type niembers and all type members will be firmly gripped thereby. The outer vertical edges of the type members will be pressed into this yieldable material while the inner vertical surfaces Aof the type members will flatten the adjacent portions of the yieldable Ymaterial .terial, such as asbestos.

so that each type member will contact with the yieldable material throughout the width of its inner surface. Consequently the type members are held firmly in position.

llVhen embossing dies of this kind are used for het stamping` they are heated to a high temperature and the compressibl'ematerial is therefore preferably ofheat resisting ma- In addition to its functions in correctly positioning the type and retaining the same in place this compressible material will also yield to compensate for the expansion and contraction of the parts of the die under the influence of heat, thereby preventing any injury to the die or its supporting` device due to the expansion of the several parts of the die.f

t will'be apparent that this die may bel used for embossing a great variety ofdata and designs on different badges. In order to change the data it is only necessary'to'l loosen the sections of the die block and make' such changes in the type members as may be de.- sired. lin many cases this may -involve only the changing of one type member ofthe date.` However, if desired', all .the data in the annular space may be changed. and the central designation may be changed by removin the center block and substituting a different block therefor. might be using the same style of badge for a horse show and for a cattle show but all the badges could be embossed from onedie by simply changing thecenter type block.
