Device for clamping and exchanging a plurality various forms on accounting typewriters.

Patented in the German Empire on September 17, 1925.

The priority of the exhibition at the 5th general office exhibition of the German Association of the Büroindustrie E.V. in Berlin on April 30, 1925 has been claimed.

The invention relates to a device on accounting typewriters, in which at the same time with a base arch, e.g. B. a sheet of the general ledger or the invoice, which is continuously provided with entries, a number of other forms, such as B. invoices., Card index cards, bank statements etc., are to be described.

Devices for clamping several forms are known; with these must

however, the forms so that they are correct by the paper guide on the platen be detected, be graded so that each subsequent arc corresponds to the distance between the guide rollers is correspondingly narrower than the previous one. This resulted in the disadvantage that one was dependent on certain paper sizes.

This deficiency of the known Einnchtungen eliminates the invention in that on the platen except for the known ones, preferably arranged below the same lateral pressure rollers for the main sheet and the one extending over the space between the two rollers Pressure roller for further pre-printing above the platen over the entire width of the platen extending foldable retaining device provided ao is for the purpose of putting forward a second and third form arbitrary, only by the distance between the lower side Pressure rollers of limited width upwards hold the second form in its position for as long as the lower pressure roller is released secure until the third form is aligned and shared with the second is clamped by the lower pressure roller.

The invention is illustrated in one embodiment in the drawing.

Fig. Ι shows the platen with the pressure rollers or rollers in the front view;

Fig. 2 shows, on an enlarged scale, the upper retaining device;

Fig. 3 gives a side view of the platen with the foldable upper retaining device in the two end positions. The lateral rollers b, b _lt, which are intended to hold the main sheet in place, press against the platen α from below. The pressure roller c mounted in the space between the side rollers, which can be made up of several parts, is used to hold on to further forms q and r. d is the upper retaining device, which consists of the rod e with rollers / sliding on it. The rod is carried by side arms g, g _t , which are connected at h to a pivotable lever i . The free end of the lever bar carries a roller which, depending on the position of the lever i, rests in a detent tn or W _{1 of} the spring 0 , which is carried by a fixed part η of the machine. The device works as follows: The base sheet p is first inserted and held by the lateral pressing rollers b, O ₁ . When the lower Andfuckrölle c is released, the second form is pre-inserted and held in its position by the foldable rail d until the third form r has been inserted and is held together with the sheet q by the pressure roller c . The roles / serve the form r as a lateral guide, so that it comes to the right place with the other already inserted sheets to cover.

70 claims:

i. Device for clamping and exchanging a number of different forms on accounting typewriters, in which on the platen (a), preferably below the same, lateral pressure rollers (b, Ib ₁ ) for the main sheet (p) and a pressure roller extending over the space between the two rollers (c) are arranged for further forms, characterized in that above the platen (a) a hinged retaining device (d) extending over the entire width of the paper roller is provided for the purpose of inserting a second (q) and third form (r) any width limited to the upper limit only by the distance between the lower lateral angle (b, ^ ₁ ) to secure the second form with the lower pressure roller (c) released in its position until the third form ( r) is aligned and clamped together with the second by the lower pressure roller (c).

2. Apparatus according to claim 1, characterized in that the upper Holding device has movable rollers that serve as a lateral guide for the third form when pushing forward.

Claims (1)

Supplementary sheet to patent specification 447 077 class 15 g group 35 ". The patent 447 077 is therefore partially for by a legally binding decision of the Reich Patent Office of November 4, 1929. declared null and void that claims 1 and 2 have been merged into one claim as follows: "Device for clamping and exchanging a plurality of different forms on bookkeeping typewriters, in which on the platen (a), preferably ₁ below the same, lateral pressure rollers (b, b ') for the main sheet (p) and one across the space between the two rollers extending pressure roller (C) are arranged for other forms, characterized in that above the platen roller (a) has a ze over the entire width of the Papierwal extending, collapsible Festhältevorrichtung (d) serving to be displaced, the third form during pre-stretching as a lateral guide rollers (f) is provided, for the purpose of pre-stretching a second (q) and third form (r) of any ^{width limited only by the distance between the lower lateral pressure rollers (b, b 1} ), the second form with the lower pressure roller released (c) to secure in its position until the third form (r) is aligned and together with d The second is clamped by the lower pressure roller (c) ".
