C OPYIN G-MACHINE.

Specification of Letters Patent.

Patented July 21, 1908.

To all whom it may concern.'

Be it known that I, EDWARD OHARLEs MAG-NUS, a citizen of the United States of America, and resident of Bonn-on-the-Rhine, German Empire, have invented certain new and useful Improvements in Oopying-Ma-l chines, of which the following is an exact speciiication.

This invention relates to copying machines of the type in which a band of copy in paper perforated or weakened at interva s, is divided or severed into separate sheets by tension.

The present invention has for its object an arrangement by means of which the disconnected sheets, discharged from the copying machine, are piled up smoothly, one on top `of the other, without use being made of special operative and movable parts.

It has been proposed before to suspend the moistened co ying sheets from a rod or'rail, one on top of the other. To attain this end the freely suspended sheets have been moved along by a rail-like part and deposited on a fixed or stationary rail. In the apparatus, as previously constructed, a reciprocating knife served the purpose of the reciprocating rail.

In the present invention for piling up the detached copying-sheets only the wei ht of the moist sheets and the motion the atter receive from the rollers of the copying machine are utilized to the end intended. In the machine the band of paper, provided at intervals with weakened transverse lines or laces, for instance perforations, is propelled by means of rollers and a belt or cord or the like, and a pair of rollers discharges the detached copies from the machine. Owing to of the moist paper the copy o r sheet as it comes from the rollers sinks and takes its course into a sort of trough, the bottom of which it strikes with its free edge. Above this bottom, or support or stop in a certain height an abutment is ar ranged in the shape of a rod, rail or the like. The sheet, after being in contact with the support offered by the bottom of the trough and receiving further motion from the rollers, is pushed against the abutment and caused thereby to bulge out beyond the same until, finally, when it is released by the rollers its end just released falls beyond the abutment and the sheet straddling the abutment, is thus hung up. As all the copies discharged from the machine are hung up on the aforementioned edge or abutment in the manner described, they form a pile-and can be taken off together.

In order to make my invention clearer, I refer to the accompanying drawings, in which a convenient constructional form is illustrated in diagrammatical manner.

Figure 1 is a side elevation, and Fig. 2 a plan view.

The lproper arrangement of the copying machine not forming the object of this invention, the diagrammatically. In this form, for example, a continuous paper band s provided with transverse perforations and supplied from a roller a, passes under a guiding roller b and between rollers c d e. From there the paper passes on to the cords-7c, carried by the rollers f and g. The roller gis connected with the roller c by means of a cord or belt. On the roller g a roller 7L is placed, to secure the continuous and correct feeding of the sheets from the cords 7C. According to this construction the support and the abutment for piling up the separate sheets or copies are combined and connected by arranging, in front of the rollers g h a trough 0, the botmachine is illustrated only tom o of which forms the support, and the The s heet bottom of the trough. n its farther progress the sheet is pushed eyond the abutment o2 and assuming in succession, the ositions shown in dotted lines l to 4 final y, on being released by the rollers g h is suspended entirely on the edge o2, as shown at 5. This operation being automatically repeated as the copies are fed along by the rollers, the sheets are thus correctly and smoothly piled up. In the construction shown, the edge o3 of the trough o is placed in proximity with the roller g in such a manner, that the paper, should it by chance adhere to the roller, is detached therefrom by the edge o3 and led into the trough.

Having thus fully described the nature of my invention, what I desire to secure by Letters Patent of the United States is 1. In copying machines of the hereindellO the bottom of Which trough serves as a support and the upper edge remote Jfrom the machine bar on Which said sheets forms a bending for the purpose debend over and collect, scribed.

2. In copying machines of the herein-described type in combination With rotating discharging rollers deliverin@ separated sheets, a trough arranged near Jhe tWo rollers and With its edge close to the roller, the bottom of said trough serving as a support for the front end of said sheets and the free edge of the trough remote from the machine serving as bending abutment and supporting rail for the paper discharged from the rollers, substantially as described.

3. In copying machines of the herein described type, a support or stop arranged near the discharging end of the machine, an abutment arranged above the support or stop and near the discharging end of the machine anda detaching. device, for preventing the aper from adhering to the lower one of me discharging rollers, for the purpose as described.

4. In copying machines of theherein described type7 in combinationv with dischargin rollers, a trough arranged Inear the tWo ro 1ers, and bearing with its one edge against the roller (g), for detaching the moist sheet from the roller, the' bottom of the trough serving as a support or stop and the Jfree edge of the trough as an abutment Jfor the paper discharged from the rollers, all Jfor the l purpose described.

In Witness whereof I have hereunto set my hand in the resence of tWo Witnesses. EDWAR CHARLES MAGNUS. Witnesses:
