SPECIFIGATIQN forming part of Letters Patent No. 699,075, dated April 29, 1902.

Application filed October 7, I901, SerialNo. 77,778. (No model.)

T0 all'whoml it may concern:

Be it known that I, SHARON CASE, a citizen of the United States,'and a resident of Mon tures in the appended claims.

Reference is tobe had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of adnplicatorembodying my invention.v Fig. 2"i s' a longitndinalsection thereof. Fig. 3 is a simi-- lar section, but showing a'different'manner of arranging the paper strips. Fig. dis a section showing a modification as to the length of the device. the carbon-sheet holder,and Fig.6 is a perspective view showing the bed-plate and rollholding frame.

The device comprises a casing 1, of any suitable material, but preferably nletal, and

having swinging connection with this casing is a cover 2. At its hinge end the cover has of the rear end of the box orcasing, and these ears are attached to a shaft 4,-which extendsthrough the casing. One end of a coiled spring 5 is attached to said shaft, theother end of said spring being attached to the cas ing, and this spring is designed to swing the adapted'to engageits upper hook end with a latch-plate 7 on the cover.

The removable bed-plate 8, over which the Fig. 5 is a perspective view of is removed.

paper strips pass, is provided with downwardly-extended sides 9, that fit closely against the inner sides of the side walls of the 'casing, and these side portions 9 are provided with indentations 10, which form bearings for -the'wires or spindles on which the paper rolls 11 and'12 are mounted. It is to be understood that two strips of paper from separate rolls are to be drawn over the bed-plate,

and placed between the two strips over the bed-plate is a carbon or transferring sheet 13. Therefore by writing with a pencil or the like on the upper strip of paper the writing will be transferred by the carbon -sheet to the lower strip. a

The carbon-strip is held in place and pre- :vented from outward movement with the strips of paper by means of a frame 14, which has side flanges lo, designed to, press the edges of the carbon-sheet downward between the side portions 9 of the bed-plate frame and the side walls of the casing.

While it is designed that paper from-two rolls only shall be used at one time, in Fig. 2 I have shown four rolls. This is merely for convenience, as after two rolls shall have been used up theother twomay be quickly put inuse. In Fig. 3-the two strips of paper, however,- instead'of being placed in rolls are folded back and forth, one layer upon another.

- Th'e devices shown in Figs. 4, 5, and 6 are similar in all respects to the devices described in'connection with Figs. 1 and- 2, excepting that they are made considerably shorter and .rbu't tw'drolls are used.

" In insertingnew rolls of paper the frame 14 is to be first removed. Then the bed-plate The side walls 9 will yield sufficiently to permit the spindles to pass into the depressions. After this the parts are to be again assembled. It will be noted that the two paper strips pass out of the end of the casing between the end bar of the frame lat and the top of the end-wall of the casing, and

when drawn out they may be readily torn ofi, having projected ends to be easily grasped with the hand. a

It will be understood that the device may be made of such size as to be adapted for counter use.
