Applicatimnld June 2, 191e. seria1-No.1o1,4o7.
To all 'whom it may concern:
Be it known that I, HAROLD D. ARENTs, a citizen of the United States, residing at ew Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Stencils; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be exact description of the same, and which said drawings constitute part of this application, and represent, in`
Figure 1 a face view of a stencil or pattern embodying my invention.
Fig. 2 a sectional view on the line 2 2 of Fig. l.
Fig. 3 an edge view of the device.
his invention relates to an improvement in a stencil or pattern, and while particularly adapted for use in connection with teaching map drawing in connection with geography, is equally adapted for use in making' drawings on a blackboard of various designs, theobject being to produce a stencil which will be readily hung over In carrying out my invention, I employ a plate or sheet 3 of strawboard, thin metal or other suitable material. From this sheet, certain parts are removed line corresponding to the outline it .is desired to reproduce. As herein shown, the sheetV is cut out to leave an outline substantially like theoutline of the United States. As these sheets are of considerable size, and as a vlarge portion lof the material is cut away, they must be reinforced to prevent a full, clear, and
leaving an outbreaking, and also means must beprovided for suspending them blackboard. To this Venol I 4 to the face of desired design cutout l be suspended over the face of theV stencil carried over the blackboard and by moving a crayon around the edge of the opening'the outline will be transferred to the blackboard when the stencil may be readily removed and a map `or other design finished.
I claim A .blackboard stencil for makingmapdrawings, comprising a relatively large rectangular stencil-sheet having portions of therewith, and suspension means applied to the frame so as to utilize the weight thereof in holding the entire rear face of the stencilsheet in uniform direct contact with the face of the blackboard.
