LA GRANGE, ILLINOIS, ASSIGNORS TO WESTERN ELECTRIC COMPANY, INCORPO- RATED, VOF NEW YORK, N. Y., A CORPORATION OF NEW YORK.'
i 4 ooMPosITE ARTICLE.
Application led October 7, 1924. Serial No. 742,130.
This invention relates to composite articles, and more particularly to stencil units.
,-In employing stencil blanks of the class.
wherein lling material impervious to ink 5 is expressed from a tissue sheet in response to the action of 'a typewriter, in some instances a so-called backing sheet is placed between the stencil blank and the platen of 'the typewriting machine. This backing sheet serves to prevent the severing of the fibers of the stencil blank when the blank is being cut or stencilized by the typewriting machine. To facilitate the use of such stencil blanks it is desirable to assemble the blanks and the backing sheets into integral units, ready for insertion in the machine.
`.An object of the invention is to provide an improved composite article.-
In order to attain this object in accordance with .the features of the invention there is provided a composite article having cooperating portions self-attached to each other', such article comprising a portion having a non-adhesive coating and another por- 125 tion having an ingredient which may be converted into an adhesive. In one specific embodiment of the invention the stencil blank, which may have a. water soluble gelatinous base such at that described and claimed in Patent 1,562,228, lissued to J. D. Grange, November 17, 1925, is assembled with a backing sheet. The backing sheet may have a waxy or, parafiin surface for -direct contact with one surface of the blank, such surface serving to preserve the blank during storage,
as well as performing the usual functions of a backing sheet. Such sheet maybe of the type described and claimed in Patent 1,562,228, issued to J. D. Grange, November 1'7, 1925. The stencil blank is self-attached to the backing sheet preferably by following the method and using the apparatus described in our copending application, Serial No. 742,129, filedv October 7, 1924, wherein a portion of the backing'sheet is heated to prepare the surface thereof to receive an adhesiye-bycausing the coatingtobe absorbed by thebody portion of the sheet7 thus leaving the surface of the portion substantially free of the coating. Moisture and pressure is then applied to a portion of the stencil blank which has been placed upon the prepared portion of the backing sheet, the moisture softening the gelatine in the stencil blankA so that it forms an adhesive and the pressure causes the' adhesive to firmly unite the stencil blank and the prepared portion of the backing sheet.
Other objects and advantages of the inl vention will more fully appear from the following detailed description takenin connection with the accompanying drawings which illustrate one` embodiment of the composite article, and in which Fig. 1 is a front elevation '0f acomplete stencil unit, and
Fig. 2 is an enlarged cross-sectionof the unit shown in Fig. 1.
' l Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several views,
10 denotes a backing sheet of fibrous material of the type disclosed and claimed in the copending application of J. D. Grange,
'Serial No.17112,103, filed October 7, 1924,
and 11 an associated stencil blank, which may have awater soluble gelatinous base, such vas that described and claimed in the c'opending application of J D. -.Grange, Serial No. 630,125, filed November 24, 1922.
The stencil blank 11 may be self-attached to the backing sheet 10, preferably by employing the method an apparatus disclosed and claimed in our copending application, Serial No. 742,129, filed October 7, 1924, wherein a restricted portion of the backing sheet is heated to prepare the surface thereof to receive an'adhesive by causing the coating to-be absorbed by the body portion of the sheet, thus leaving the surface of the portion substantially free of` the Wax or paraffin. Moisture and pressure are then applied to a portion ofthe stencil blank in contact With the prepared portion of the backing sheet. The moisture softens the gelatinous base of the stencil blank so that it forms an adhesive and the pressure causes the adhesive to firmly unite the stencil blank and the prepared portion of the backing sheet, as shown at point 15 in Fig. l.
It is, of course, to be understood that the coating of paraffin is non-hygroscopic.and
impervious to Water, and hence Will prevent the backing sheet4 from absorbing the essential moisture in the stencil blank and thus preserves the blank ready for immediate stencilization, as Well as protects the fibrous material of the sheet'from the moistening fiuid used during the stencilization. This is very important,l inasmuch as it prevents the fibers of the backing sheet from p absorbing moisture, thereby insuring that the characters'being cut in the stencil are accurately and sharpl/y defined.v
A stencil unit embodying this invention is of simplev construction, of a minimum number of co-acting members, and may be stored for long periods of time and in a minimum amount of space. units are packed in pairs with the blanks thereof in contact, the paraiiin coat-ing of the backing sheet not only serves to effectively prevent the escape, by.evaporation, of the essential moisture-in the stencil blank, but also to protect the blank from any eX- cess moisture in the storage atmosphere; thus the stencil blanks are maintained in condition for immediate stenciling throughout long periods of storage.
What is claimed is:
l. A composite article comprising a Waxy coated backing member having a portion of its surface' repared for an adhesive, and a second memiber attached to the prepared surface of the first member, said second member having a bonding ingredient Which is rendered adhesive by moisture.
2. A composite article comprising a backing member having a portion of its surface covered With a non-adhesive, impressionable substance and a portion of said surface capable of accommodating an adhesive,
lVhen these blank.

3. A composite article comprising a member having an impressionable coating which has a portion of its surface prepared'for an adhesive, and a second member attached to the prepared surface of the first member, said second "member having a gelatinous ingredient Which is rendered adhesive by moisture.
4. A composite article comprising a paraln coated member which has a portion thereof free from the paraffin and is in condition to accommodatel an adhesive, and a second member attached to the paraffin free surface of the first mentioned member, said second member having a bonding ingredient which is rendered adhesive'by moisture.
- 5. A stencil unit comprising a paraffin coated backing sheet having a portion thereof prepared for an adhesive and a stencil sheet attached to the prepared portion of the backing sheet, said stencil sheet having a bonding ingredient of gelatin.
