摘要

The ownership and exclusive exploitation of a grouping of templates of paper, cardboard, celluloid or any other sheet material, in each of which one or more perforations are made corresponding to different elements of the same set, so that placing successively the templates in an orderly manner on the same paper, and tracing on it lines that follow the edges of the referred perforations, well, filling with pencil or color the portions of paper that the same perforations expose, the diverse ones can be produced details of the same drawing, in an almost machine-like manner, which allows the use of such groupings of templates in the execution of manual works that are usually carried out in kindergartens.
