MANIFOLDING APPARATUS.

Application tiled January 9, 1928, Serial No. 245,549, and in Austria Hatch 2, 19117.

This invention relates to an apparatus for manifolding in eneral and particularly for duplicating boo eeping entries. A

A process is known for manifolding such entries, according to which simultaneously 4with the orifrinal entry a mirror or reversed .copy thereofa is prepared, which is capable 'of giving oil' part of its color or ink to an other paper and which is `'transferred line by line to cards or sheets by exerting a powerful pressure on the front face of the stencil. If before making the impression, the

cards are moistened, it is possible to obtain numerous clearly legible copies with a single stencil, but it is necessaryin that case to exert a considerable pressure in printing.

In spite of its advantages for bookkeeping purposes, this process has not been largely adopted in practice as up to now an .ap-

paratus did not exist which could be manipulated in a simple manner, manufactured at a small costv and yet would enable the work to be done quickly without too much effort.

The apparatus according to this invention solves this problem. It substantially consists in a slide adjustable in the direction of height of a bed or plate, which is formed into a device for clamping or fixing one longitudinal edge of the stencil, a moistening device slidably mounted in a cross-guide of the bed-plate and intended for moistening the sheet on which the manifold impression is produced, and a pressure or printing member, also movable in a cross-guide, for reproducing the impression. The moistening device and the pressure or printing member are preferably mounted on a fork, between the branches, or prongs of which is placed the stencil, owing to which the moistening and the printing may be effected in a single operation.

A construction according to the invention is illustrated by way of example in the ac companying drawings:

Figure 1 shows the apparatus in perspective.

Figure 2 is an elevation, partly sectional, of the most essential elements 0f the lpparatus at an enlarged scale.

Figure 3 a cross-section according to the line 3--3of Figure 2 and Fi r e 4 a sectional view of the line spacing evice.

1-is the base plate of the apparatus with 55 a bar or rai1'2 secured edgewise thereto and a slidably mounted rail or slide 3, the distance between these two rails being equal to the width of the cards 4, on which the impressions are to be produced. 5 are two 60 marks indicating the distance of two lines for the purpose of facilitating theline adjustment of the card.

The stencil 6- may for instance be made by means of a typewriter, carbon paper be- 05 ing inserted so that its colorin side touches the back of the sheet, on which the types are striking, whereby simultaneously with the writing on the front of this sheet a mirror or reversed copy of this writing is obtained on its back.

The slide 3 consists of two piirts lengthwise pivotally connected by means of hingejoints 7 and is slidably mounted in a uide 8 of the base plate.` Between the sai two 75 parts of the slide, which in Figure 1 of the drawing are shown in the o en osition, the stencil 6 is to be fixed. or t is purpose the o ne part of the slide is preferably provided with pins 9 and the stencil with cor- 80 responding perforation. A line spacing device of known construction, as shown in Figure 4, may be provided, which is operated by the handle 10 and which prevents the slide from being moved to fractions of the height of aline.

11 are guide rods, ixed to a head 12 and attheir other ends connected to one another by means of a frame 13 provided with a pres sure button 14.

The rods, or more exactly expressed their head 12, are journalled by a joint 15 to a support 26 of the base plate, so that the `rods can turn up into an oblique position shown in Figure 1 under the action of a. spring 1.2* 95 placed underneath of the base plate and engaging with a downwardly extending part of the head 12.

The rods 11 are guiding the support 18 of the pressure roller 16, which ispressed down by springs 17. A rod 19 is secured parallel to the rods 11 to the guiding body of the said roller support, is guided in the frame 13 and at its outer end provided with a handle 20. To the. latter a resilient (steel) band 21 is bodily connected or secured so as to extend inwardly parallel to the rods 11. This elastic band carries at its free end a wiper 22 of an absorbentr material for the moistening. The wiper is inserted in anl aperture ofthe bottom of a little tank or receptacle 23, which is carried by the end of the band and can be closed up by a cover 24. For the purpose of maintaining the entire body of rods andv band against the action of the spring 12a in the lowered position, the' lower part of the frame 13 may be held clamped by a screw 25.

The rod 19 carrying the pressure roller 16 I' and the resilient band 21 carrying the wiper are thus forming a fork, between the branches or prongs of which is placed the stencil fastened to the slide 3 on its one edge. By a suitable movement of the slide 3 the stencil is brought into such a position, that the pressure roller 16 is situated in the line to be reproduced, The line vof the card 4, on which the entry is to be copied, is then set by means of the marks 5. The frame 13 is now pressed down, so that the roller 16 is pressed downward on the stencil,l whilst the wiper 22 is in this position, owing to the re-f siliency of the band 21, pressed against the card 4. If now by means of the handle 20 roller and wiper are pulled along the guiding rods 11, the set line of the card 4 is moistened and immediately thereafter the writing of the stencil 6 is transferred to the card by the strong pressure of the spring controlled roller following the wiper. When the roller has arrived at the end of the line, the pressure on the frame 13 is released and the fork pushed'back, so that all parts will again be in the position as shown in Fig. 1. The card 4 is thereupon replaced by another one, on which the same entry is to be made.

VIn the .operation of printing it may happen, that the roller 16 runs to the edge of the kstencil and the wiper 22 is moved beyond the edge of the card 4. The stencil will ythus not be'supported anymore by the band 21 and for 4moving the printing device back .into its original position it should be necessary to re-introduce it between the roller 16 and the band 21. In order to avoid such necessity needle-like little rods orrails 28 are secured to the frame 13, which are supporting the stencil also in the case of the wiper trespassing the edge of the card.

For the purpose of making the already transferred lines of the stencil, there may be provided adjustable needles 27 on the support26, tov which the head 12 is journalled. wWhen the latter is pressed down, these needles are by the action of a plate lowered and will be driven ythrough the stencil, the

with suitable spaced holes 32 lof the base part of the slide 3 and at its rear end it is by means of a link 33 connected to the handle 10, by which the line spacing device is actuated.

The apparatus according to this invention is particularly adapted for lmanifolding line by line, it may, however, also be used as ordinary duplicating apparatus reproducing the writing on kthe entire surface of the stencil in one operation, For this purpose itis only necessary to make the length of the roller 16 and of the wiper equal to the height ofthe stencil.
