Description

Paper guiding device on typewriters, typewriters and the like .. The invention relates to a paper guide device with two before Platen independently of one another arranged so that they can be pivoted forward. Devices of this type are for the purpose of easy insertion and alignment of prepacked forms has already been used in typewriters, typewriters and the like.

According to the invention, one of these paper pressure devices is now designed as a straightening rail, the straightening edge of which by a number of whole simple line spacings is away from the baseline. It is used to align forms, which two line number scales offset from one another by the same number of line spacings exhibit. The second pressure device is used by a pressure only, Above the alignment rail, press the pre-printed sheets against the paper roller Paper pressure bar formed, which when cutting off, venken the upper edge of the stacking sheets exceeds.

The use of forms that are offset against each other on the edge Line number scales are provided, is already known in such devices, where perforations are provided next to the scales, by means of which 'the form is hung on pins of an alignment rail, which corresponds to the scale offset are away from the baseline.

In these devices Avei such pin rails were arranged, the pins on one of the rails were opposite to a different number of lines of the baseline of the writing offset than those of the others the forms have correspondingly differently offset scales. The pen rails did not act as pressure rails. Rather, the brackets only loosely laid the form to the platen. When pivoting the bracket was created; especially with thinner ones: Forms, the risk of tearing the form. Otherwise, it was slow to manufacture of the forms, as the holes are not made at the same time as the scales special care to ensure that the row of holes matches the row of scales be used.

Also known was a device with a front, from below holding rail to be swiveled tangentially in front of the stacking sheets, the with direction indicators adjustable on it, and with in front of the platen arranged directional block provided with pins. The clip-on sheets can be attached to these pins be hung up if they are provided with perforated edges. One on the machine The upper pressure rail, which is also provided and can be swiveled forward, is used for pressing of continuous leaves. .

The handling of the device according to the invention is opposite these known devices are considerably simpler and more trouble-free. After this line-oriented insertion and alignment of the first form of any width with With the help of the alignment rail, the upper one becomes the upper one by pivoting the upper pressure bracket First put the end of this form behind the upper bracket and then through Pivoting back the upper bracket pressed securely against the platen and thus held in place. The second and following form are then in the same simple way aligned and set. Neither on selection. correct forms Particular care is required to avoid damaging the forms to be used, still need special adjustments of the alignment means for different form shapes or sizes to be made.

About the pre-inserting or the lateral alignment of the pre-positioned elbow particularly easy to design and thereby relieve the operator even more, are the adjustable tabs on the alignment rail for the individual forms accordingly different, z. B. by color.

Fig. I shows a left side view of the paper cart: a typewriter, in which all of the paper pressure means are shown in the lifted position from the platen and individual parts are drawn in section.

Fig.2 is a view of the device according to Fig. I, but finished to describe the forms.

Fig. 3 to 8 show the individual positions of the alignment rail in a side view and the paper pressure rod again when inserting. 01 Fig. 9 shows one in the direction of the arrow A of Fig. 2 seen top view of the pre-inserted forms, the collective sheet and the alignment rail with tabs, Fig. io a narrow form with a double scale and Fig. i i a wide form with a double scale, the left columns of which extend to "Price" column match the columns in the narrow form. On the side panels 3 and 3a (Fig. I and 2) of the roller frame, a shaft 43 is rotatably mounted to which sleeves 44 and 44a are placed. On radial extensions of the sleeves are Levers 45 and 45 "are fastened by means of screws with tabs bent approximately in the middle of the lever. At their lower ends, the levers carry the shaft 46 on which the paper pressure rollers 42, advantageously two, are arranged displaceably and rotatably. Flaps 45 'and 45 " serve as a handle for pivoting the levers 45 and 45a, on which the paper insertion plate 47 for the main arch is fastened by means of screws 48 and 48a and on which further Pins 49 and 49a are arranged with a broad head, the shafts in spacious Grooves 50 and 50 ″ on the side parts of the carriage 3 by means of rivets 52 and 52 ″ and 3 ″ rotatably arranged levers 5 i and 5 ia are able to collapse. Tabs 50b and 5ob 'enable the levers 5 i and 5 1a to be handled conveniently.

The paper insertion plate 47 rests on rollers 53 and 53 a, the on the paper feeders which are arranged displaceably on the main paper insertion plate 5 54 and 54 "are attached. The springs 55 and g5" influence the levers 45 and 45, in the opposite direction of the clockwise. The shaft 43 penetrates around the pin 6 rotatable lever 7 in a slot 56 which is central to the pin 6 and is thereby limited the pivoting movements of the lever 7. A U-shaped bent around the shaft 43 Sheet 57 touches with. his thighs' almost the platen 2 and prevents that Forms slip through between platen 2 and shaft 43.

The axle 58 is rotatably mounted in parts (not shown) which are fastened to the side parts 3 and 3 "of the roller frame. Arms 59 and 59a, only the right one is shown in Figs carry the rail 6o with the paper pressure rollers 6i, which are arranged displaceably and rotatably in a known manner. On the axis 58, a tube 62 is rotatably mounted over the entire length between the arms 59 and 59 ″ , on the ends of which two levers 63 and 63 ″ are pinned which carry a pressure rail 64. Both the frame 59, 60, 59 "and the frame 63, 64, 63" can be lifted from the platen 2 in a known manner by pivoting about the axis 58.

Around the rail 64 encroaching and slidably arranged on it Tabs 65 (fig. I, 2 and 9), which are used for the lateral adjustment of the various Pormulare are appropriately colored or marked differently, are by means of of the handle 65 'set for the side position of the corresponding forms. - -The The scale rod 64, which serves as an alignment rail, lies in accordance with the line division of the forms drawn in Figs. i o and i i with their straightening edge five full _ line spacings above the baseline. So is z. B. the alignment rail 64 with its directional edge on the scale line i -the scale I. of the forms, so can the horizontal column of scale II marked i can be described: Of course the scales I and .II can be changed to any number of whole, i.e. more. or less than be offset from one another by five line spacings. However, the removal of the Alignment edge of the alignment rail from the baseline of this offset in each case correspond. Attch the collective archS can, as Fig. 9 shows, with the same scales be provided.

Before now to the mode of operation of the actual invention. , received is to be the mode of operation of the device for lifting the platen beyond the switching position and the pressing and releasing of the. the lower paper guide rollers and the paper guide plate.

If the lever 7 is moved from the position shown in Fig. 2 to the position shown in Fig. i pivoted position, the lever 8 is about the pin 6 and over the Rod i i also the lever 14 together with the axis 13 is pivoted in the clockwise direction.

The downward movement of the rod i i- relative to the roller frame and carriage frame only takes so long; until the roller io "carried by the pin io rests on the stop 16 arranged on the right-hand side of the carriage frame i. The levers 8 and 14 then cause the rod ii to be displaced in the direction - of the arrow a, so that the rod ii moves onto the in its trajectory protruding nose iga of the stop i9 acts and this is pivoted slightly in the opposite direction of the clock about the bearing pin i8 of the platen but is not able to move further down, the lever 8 now swivels around the roller serving as a fulcrum in the clockwise direction, so that now the pin 6 attached to the roller frame and the platen 2 are lifted, and as a result of the previous pivoting of the stop lever i9; beyond the switching position caused by the stops 2o. Due to the fact that the rod ii is unable to move further downward, the pivot point 12 is also held stationary with respect to the carriage frame i, so that with further upward movement of the roller frame - the lever 1 4 also reverses. the point 12: executes a swivel movement in the clockwise direction, whereby the axis 13 is rotated further in the clockwise direction. Here the cam ii ″ of the rod ii acts on the nose i9 of the part i9 and holds it in the position shown in Fig. 2. As soon as the lever 7 is pivoted, the axis 13 acts like an eccentric on the legs 36 of the lever 23 and swivels it around the axis 22 in the clockwise direction; so that the levers @ 23 act on the pegs 35 of the U-rail 30 and thereby the levers 29 together with the paper guide rollers z5 and z6 and the rail 30 counter to the action of the springs 31 of As can be seen from Fig. i, when the paper guide rollers are depressed, the rear side of the paper guide plate remains in contact with the platen due to the light action of the springs 3.9. Due to the greater weight of the lower rear paper pressure rollers z5, the roller levers pivot 29 in this case counterclockwise around point 35 when the rollers are pressed in the manner described The pivoting now lasts until the front Push rollers 26 against the front window of the paper guide plate 37. The lifters 124 for the paper guide plate 37 are moved in a similar manner, with the axis 13 acting on their legs 24,, in the manner of an eccentric, whereby the lifters 124 are pivoted about the axis 2z in the clockwise direction. Here, the paper guide plate is pressed off on the front side of the platen roller 2 37, SO däß arises a wide opening between the platen and paper guide plate: It is thus the paper guide plate 37 through the - front kept lever 24 in its lower position and by the springs 39 it prevented from turning around point 38 in the opposite direction of the clock and resting with its leading edge on the roller; what would happen without the arrangement of the spring because; As mentioned above, the paper guide rollers 26 due to the excess weight of the paper guide rollers 25 and 25 would apply to the same. What is further achieved here is that the paper guide rollers 25, 25, t do not protrude through the paper guide plate 37, which is of particular advantage for the pre-plugging method.

Independent of the device for lifting the roller and pressing it on and off of the lower paper guide rollers becomes the Lever mech'anisinus for moves the upper rear paper pressure rollers.

If you press on the tabs 50b and 5o6 of the levers 51 and 51Q, the pins 49 and 49, the levers 45 and 45 "slide out of the grooves 5o and 5o" of the levers 51 and 51Q and along the upper edge thereof, with the on the shaft 46 slidably arranged rollers 42 are pressed against the platen under the action of the springs 5 5 and 55 ". It should be noted that the upper rear paper pressure rollers 42 are to be adjusted so that only the main or collecting sheet S at its edges in The alignment rail 63, 64, 61 and the paper pressure rail 59, 6o, 59 ″, on the other hand, alternately hold the pre-inserted forms, as described in detail below.

The handling and mode of operation of the device is now as follows: Let it be assumed; that the platen 2 is in its normal, ie lower position is located. in which the hand lever 7 assumes the position shown in Fig. 2 and all paper pressure means are in contact with the platen 2 as shown in Fig. Advantageous Now the upper rear pressure rollers 42 are first removed from the platen 2 lifted off by levers 45 and 45 "by pressing on their handles 45s 45" as opposed to the action of the springs 5 5 and 5 5Q clockwise around the shaft 43 in the in Fig. I shown position versrhwenkt in which they snap by snapping the Pins 49 and 49 "are held in grooves So and 5o" of levers 51 and 51Q. The pressure roller bracket 59, 6o, 59 "and the alignment rail 63, 64, 63Q pivoted into the position shown in Fig. i, d. H. they are also used by the Platen lifted off. So now there are only the lower paper guide rollers 25, 26 together with the paper guide plate 37 on the platen. Now -will be first the collecting sheet S between the paper insertion plate 47 or the pressure rollers 42 and the platen inserted until its leading edge against the rear paper guide rollers 25. Then the platen 2 by means of the known, not shown roller knobs in the direction of the arrow B (Fig. 2) turned until the collective sheet S with its first writing line has reached writing height. Then the pressure roller bracket 159, 6o, 59a is attached to the platen applied, whereby initially the collecting sheet S on the front of the platen 2 is held. To it also on the back of the platen 2 but only on To be able to hold the edges, the rollers 42 are initially set to the width of the collecting sheet S set. The levers 51 and 51Q are thereupon by applying pressure to the Handles 5 if and, 5 if pivoted clockwise, whereby the pins 49 and 49Q released and the levers 45 and 45, including the shaft 46 'and the pressure rollers 42 by the action of their springs 5 5 and 5 5Q "in the opposite sense of the Be pivoted clockwise about the shaft 43, so that the pressure rollers 42 the collecting sheet Press S onto platen 2.

Now the lever 7 is from the position shown in Figure 2 into the Position according to fig. i pivoted, whereby, as already described, the platen 2 is raised beyond its toggle position while the paper guide rollers 25 and 26 and the paper guide plate 37 from the platen 2. be pulled.

The resulting distance between the platen 2 on the one hand and the rollers 25 and 26 and the paper guide plate 37 on the other hand now a convenient insertion of the pre-positioned forms. The first pre-positioned form V1 (Fig. I o) is inserted from the rear or from the front so that it is between the paper insertion plates 47 and 5 of the platen and the paper guide plate 37 slides through. On that the straightening rail 64, which has previously been pivoted away from the platen 2, is held was (Fig.3), against = the pre-inserted form V1, -which, for example, is the one in Fig. I o shown should be narrower, created (Fig. 4). This is now aligned with the alignment rail 64, in such a way that the scale lines r the in fig. Since the Alignment rail 64 is exactly five line spacings above the font baseline, so is located Now the writing line of the marginal scale II marked with the scale mark i of form V1 in writing.

In order to be able to define and identify the position of this form on the side of the collective sheet, tabs 65 and 65 "(Fig. 9) are attached to the M.chtschiene 64, which may be marked with V1 or, for example, can be identified by a red color These tabs 65 and 65 " thus serve as lateral positioning marks for the edges of the pre-positioned form V, If the form V1 is aligned according to the font size and laterally to the collective sheet S, then the pressure roller bracket 159, 6o, 59" is clockwise according to Fig 5 pivoted, whereby the upper part of the pre-positioned form V1 protruding beyond the alignment rail 64 is curved to the right. However, as soon as the pressure roller bracket 159, 6o, 59 ″ assumes the position shown in FIG - Form V1 automatically to the left. Once this is done, - the pinch roller bracket. 59, 6o, 59. as shown in Fig. 6 again applied to the platen. The directional slide 64 can now be lifted off again, ie brought into the position shown in Fig. 7, in order to insert a further form V2 (Fig. Ii), since the form V is now held by the pressure roller bracket 59, 6o, .59Q will. As can be seen from a comparison of Figs. Io and ii, form V2 is significantly wider than form V1. Form V2 is now to be aligned with form V1 in such a way that the first line of the same at writing height and the various columns "old balance", "fol." Etc. also coincide. In this case, no special tab needs to be placed on the alignment rail 64 for the left edge of the form V2, since the left edge of the form V2 must coincide with the left edge of the form Vi. It is therefore only necessary to set a special tab 65b, which has the designation V2 or z. B. can be provided with blue color. The form V is now again inserted from the front or from the rear between the platen 2 and the paper guide plate 37 and the alignment rail 63, 64, 63Q according to FIG. 3 is placed on it again. Then the pre-positioned form V2 is aligned with the scale lines marked i of the marginal scales marked in Fig. Ii at I in height and with the right edge of the sheet facing the tab 65b. To align one of the sheets laterally, it is not absolutely necessary to use two tabs 65 and 65 ″, but rather only one tab is sufficient, e.g. tab 65Q for form Vi and tab 65b for form V2 Alignment of the form V. is completed, the Andrukrollenbücke159, 6o, 59. is swiveled out into the dotted position shown in Fig. 5 and placed on it again as shown in Fig.6, whereby the pre-positioned forms assume the position shown in Fig.2 the lever; swiveled from the position shown in Fig. i to the position according to Fig.2, whereby the platen 2 is lowered again and the paper guide rollers 25, 26 and the paper guide plate 37 are again placed on the platen, whereupon the labeling can be carried out .

It goes without saying that sheets of carbon paper must be inserted between sheet S and form V1 and between this sheet and form V_. For the sake of clarity, these are not shown in the figures. From what has been described it can also be seen that the new arrangement of the alignment rail and the double scale on the forms and their division by five or more or fewer lines makes it possible to put any narrow forms in front of any wide forms. Because it is obvious that the alignment by means of the double 'scale device can be done easily and precisely, so that there is no fear that the numbers or letters will end up on the wrong line. The lateral alignment is also easily made possible by the tabs 65, 65 and '65b of the alignment rail 64', you only have to remember the tab color selected for the individual forms. To make things easier, however, the forms can be provided with a color patch corresponding to the color of the associated tab, or forms of different colors can be used at all.

The deflection plate 57 is intended to prevent the front-mounted Forms or the forms protruding behind the pressure rollers 6 i between the platen 2 and the shaft 43 can get.

It should also be mentioned that the rider of course not only to the side Setting the edge of the sheet, but also for setting a column line or the like. Like. Can serve.

Particularly noteworthy in the device is the advantage that the Lower paper guide rollers 25, 26 are not required at all for pre-pinning are, but that these only need to be lifted once: and also the lifting - the platen only once: is required, whereupon as desired without difficulty many and randomly successive forms are inserted in front of them can.
