Synthetic resin interlocking die cut letters for application to fabric backing

Claim 1

The invention comprising: a plurality of separate alphabet letter characters formed of thin, normally solid synthetic resin sheet-like material which can be rendered at least partially flowable, said letters being configured for placement in any desired order and in an end-to-end relationship for forming words or expressions, each of said letter characters being configured to present, adjacent the left- and right-hand ends thereof when placed for normal left-to-right reading of the letter character, respective interconnection surfaces for complemental script-type interconnection of a plurality of the letter characters in said end-to-end relationship to form a word or expression on a cloth backing, said interconnection surfaces including a male connection surface at one end of each letter character, and a complemental female connection surface adjacent the remaining end of the letter character, the complemental interconnection surfaces of separate letter characters being configured for blending together by virtue of physical flowing together of said material adjacent said surfaces, when said letter characters are interconnected and said material is rendered partially flowable, for substantially eliminating any lines of juncture between said letter characters in said word or expression and creating a substantially integrated and unified word or expression, said material having the property of bonding to said cloth backing when the material is rendered partially flowable for securing said word or expression to the backing simultaneously with said blending together of said interconnection surfaces.
