Application tiled September 2, 1904:. Serial No. 223,096.
Be it known that I, JOSEPH S. DUNCAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of IllinoIS, have invented new and useful lm rovements in Stencil-Frames, of which the ollowing is a s eciiication.
The o ject of this invention iS to provide a stencil-frame of simple and inexpensive construction and rovlded with an index-tab formed integra ly therewith to adapt the stencil for use in a card-index System.
ln the accom anying drawings, Figure 1 from which the frame is formed. Fig. 2 is a plan view of the frame. Fig. 8 shows the stencil in the frame. Fig. 4 is a sectional view on the line 4 t of Fig. 3. Fig. 5 is a detail sectional view on the line 5 5 of Fig. 2.
The blank 5, Fig. 1, is 'stamped out of a single sheet of metal and bent to form the skeleton irame 6, Fig. 2 which is entirely open at The frame is provided with side and end channels 8 to receive the edges of the stencil 9, Fig. 4, which is slipped endwise into the frame at one end thereof and moved along to its final position, as showninFig. 3. Anindex-tab 10 is formed out of a portion of the material which is cut out of the trame to provide the opening 7. This tab is left projecting into the mening of the frame 'when the blank is formed, Fig. 1, after which it is bent upward behind and above the upper side oi the frame; The tab ma be located at any position between the en S of the frame and one or more tabs may be provided, as desired. Letters, numerals, Or other characters ma be stamped, printed, or affixed in any suita le manner to this tab as an index or for an other purpose whatever, and l have oun it satisfactory to print directly u on the tab.
To fac' tate the operations of inserting the stencil in the frame and removing it therefrom, l rovide a channel at the entrance end of the iirame, with a sectional up er wall formed by the projections 1l, W 'ch are stamped up from the blank, as clearly shown in Fig. 5. Thel end ofthe blank which forms the entrance end of .the frame is bent upwardly at an angleto the body of the frame to form a Shoulder 12, beyond which this end of the blank is bent downward .and back under the shoulder in the form of a bead 13, p
l ployed; but ll consider t which iprovides a smooth outer edge at this end o the trarne, 4corres onding to the smooth edge at the other en and at thesides of the frame. Pro'ecti'ons :11 are cut eut of the shoulder 12 an bent at an angle thereto and in a direction preferabl parallel with the b ack of the frame. The ontwall of each side channel is cut away at 14 at4 the entrance end of the frame, so that the stencil may be readily inserted in said channels and moved along endwise into proper position in the frame, and the rear end ofthe stencil can be easil arranged beneath the projections 11, whic will hold the Stencil securely in place in the frame. Any number of projections 11 which will answer the pllrpose may be emee projections amply suicient, and they are spaced a art, so that access can be had to the rear'en of the stencil at any time to disengage it from the pro'ections preliminary to removing the stencil om the frame. The stencil can bedisengaged from the projections b inserting the ngennail or a pm between t e Stencil and the shoulder 12, and this disengagement can be e'ected without injuring the stencil.
My improved stencil-frame is simple and inexpensive in construction and is adapted for use in a card-index system without additional cost of material.
The invention is particularly useful in connection with subscription-lists in which each subscriber has an'individual number, for in such cases the number can be'placed on the tab to correspond with the subscribers name which appears on the stencil, and in this way the number is always associated with the subscribers name, but does not ap ear in the printed impression from the stenc' The construction of the frame is also advantageous in the respect that it permits the arrangement of the stencil in the frame and its removal therefrom easily and quickly and without danger of mutilating the stencil.
i do not limit the invention to the exact construction and arrangement of parts herein Shown and described g but A skeleton stencil-frame formed out of a single sheet of metal with side and end channels to receive the edges of the stencil, Said frame having an opening between its sides and ends to permit an impression to be taken roy fromthe stenciland Vprovided with a tab to g eene-l.
