To all whoml it may concern,.-
Beit known that I,`GEORGE I ImLrKan, a citizen of the United States, residing at Chlcago, in the county of Cook and State of Illinois, have' invented certain new and useful Improvements in Attachments for Cuttlng Stencils for Use in Duplicating-Machines, of
which the following is a speciication.
- As ordinarily Y used each stencil sheet is mounted upon a backing of stiff paper or similar substance, and between the stencilpaper 'and the backing is a sheet of boltingcloth, which is adapted to remove the wax from the rear face of the stencil-sheet, and in front of the stencilheet is positioned a piece of tissue-paper for removing the wax om the face of the stencil-sheet when struck 'by the type. This arrangement is objectionable, for the reason that it necessitates the employment of four different layers of fabric or paper, which must be positioned in the type-'writer before the voperation of cutting the stencil can be performed. VAnother objection to this arrangement lies -in the fact that the tissue-paper superimposed upon the face of the stencilheet is frequently cut by the type, so that some of the waX will adhere to the type, clogging the type and rendering it uniit for use."
The object of the present invention is to overcome the difficulties above enumerated and to 'provide a more easily-manipulated stencil' to be used in combination with a strip of fabric adapted to be carried b the ribbons ools of the type-writer, thereby obviating t e necessityfor using a sheet of tissue-paper of the full size of the stencil and at the same time providing a more reliable and satisfactory means for removing the wax from the stencil-paper.
The invention consists of the features ofV construction and combination of parts hereinafter described and claimed.
Figure 1 is a face view of a stencil-sheet, showing a strip of fabric mounted upon the ribbon-spools vof a t e-writer; Fig. 2, an edge view of the Astencil-Sheet and mounting therefor; Fig. 3, a view showing the relative position of the sheets in actual use.
In the drawings, A indicates a stencil-sheet which can be covered with wax or an other suitable composition of the kind or ari] employed in the .l manufacture of stenc' stlrilp Y w' thus be seen that the stencil-sheet is insheets, and the stencil-sheet is pasted to the inner face of a mounting B, formed of stiff paper or other suitable material and consisting of a front flap C and a back flap D, as best shown in Fig. 2. Into the mountingis loosely inserted a sheet E of bolting-cloth or similar fabric, which serves as a backing for the stencil-sheet and is adapted to remove the wax from the rear face thereof when struck bythe type in the operation of cutting the stencil. The reason for asting the stencil-sheet to the forward ilap C) is that the stencil-sheet can be used but once and the bolting-cloth can be used re eatedly, so that it is desirable for each stericto be rovided with a mounting of the character in cated, allowing the same bolting-cloth'tc be inserted successively behind different stencil-sheets.
Th wax is removed from the front face of the stencil-sheet by means of a strip F of silk or other suitable fabric, which must'be soft and pliable to perform the work intended, and such strip is of a pro er Width to be carried by the ribbon-spoo s G of an ordinary t e-writer. The strip may be of any suitab e length and can ordinarily be-positioned in place by securing the end of the strip to the end of a type-writer ribbon H, which enables the same machine' to be usedeither as a type-writer or for the purpose of cutting stencils, although in some cases it is desirable to make the strip of the full length of a typewriter ribbon and fasten it directly to the ribbon-spools. Y.
In use the backing of bolting -cloth is 'loosely I inserted into the mounting for the stencil-sheet and held between the uplper and lower flaps, after which the stencil-s eet and the ibacking are inserted into a type-writer in the usua manner and the ribbonspools are turned into a position to bring the silk across the face of the stencil-sheet. It
terposed between two ,layers of fabricpf a Vsuitable character to evenly and erfectly remove the wax from the face an back of the stencil-sheet when struck by the type.
IOO
The strip, which ocilpies the osition or a type-writer ribbon, obvious always be interposed between the type an the stencilsheet, so that the operation of cutting the stencll can be performed 1n exactly the same way as the operation of type-writing, and v :there will be n o necessity for removing the y'pe-Writer ribbon entirely from the spools; but the spools will perform their ordinary function of giving lon itudinal movement to the strip of material, t ereby brin ing different portions of materiafsucce'ssive y between ,fthe .type and the stencil-paper, so that the- -wax will not be collected on a single portion of the strip,butwill be uniformly distributed over a considerable area. In machines which are used exclusively for the cutting of stencils the strip can be of the full size of a type- Writer ribbon, so that a single strip will serve its function for a long period of time before a sufficient amount of wax is collectd on the strip to interfere with .its operation. At the same time the cost of operation is reduced to a minimum by reason of ,the fact that the Strip is-narrow and a fine grade of silk can be -employed in place of the tissueaper, which must of necessity be ofthe ful size of the Stencil-sheet without increasing the cost to i the operator.' Another feature of value is the fact that' in preparing. the stencil-paper for the market the only operation to be performed is pasting the flap-mounting to the stencil-sheet, thereby obviating the necessity for additionally asting a sheet of paper and backing, which simplifies themanufacture to that extent. By providing but two layers of material to be carried by the type-writer cylinder instead of four, as are ordinarily used, less difficulty is experienced in mountT ing the stencil on the type-writer cylinder, and the operation of cuttmg the stencil as a whole is simplified. The stencilafter being eut will be more perfect, for the reason that the silk strip employed in the cutting operation is highly superior to a sheet of tissue-paof a silk backing-l remove the waxl sheet, a stencil-sheet and a narrow stri of.
silk adapted to be carried by the rib onspools, the stencil-sheet being interposed between the backing and the strip, and the backing and strip being adapted to receive and remove the particles of Wax on opposite sides of the stencil-sheet when the strip is struck by the type, substantially as described.
3. The combination of a stencil-sheet, aV
flap-mounting at the head ofthe sheet secured thereto, a backing-sheet loosely insert-- ed between the flaps of the mounting, and a silk strip adapted to be securedr to a type- Writer-ribbon and carried by. the ribbons ools, and superimposed upon the stencilslie'et and adapted in combination with the backing to receive and remove the particles `of wax on o posite sides of the'stencil-sheet when the sil strip is struck bythe type, sub.
stantially as described GERGE L'. HDLLIKER.
