COPYING-MACHINE.

Application filed. November 25, 1913.

To all whom it may concern: v

Be it known that I, RICHARD BERGER, a

d subject of the King of Bavaria, and residing copying paper drawn off a roll, the control of the auxiliary mechanisms by the copying paper being such as to cause the starting and stopping of any of the said mechanisms to be dependent on the movement of the copying paper and in accordance with actual requirements. For this purpose a feeler or equivalent device isprovided which comes into operation with varying sizes of papers for copying, the actuating of the feeler not being dependent on a predetermined number of revolutions of a part of the machine, say the copying roller, but being dependent on the length of the sheets. i

In order to use the copying paper from a storage roll for actuating the feeler, the former'is provided with marks or perforations, at suitable distances apart, into or with which the feeler can engage. The

thin copying paper is not strong enough to transmita more or less great force. This difficulty is overcome by causing the copying paper, with which-thefeeler is in contact without producing any appreciable effort thereon, to impart a slight motion to the feeler of such a nature asto require no effort on the part of the copying paper. For example, gravitation can be utilized so that the first. slight motion of the feelercauses the latter to be coupled direct or through intervening parts with the mechanism to be set in motion by the. copying machine, while at the same time the feeler is allowed or caused to return to its initial position.

The improvement is shown .in the annexed drawings, in which: 1

Fig. .3 a detail and Fig. -,4 a perspective view of the copying paper in connection with the controlling mechanism.

The copying-strip 1, drawn off the roller 2, passes over a roller 3 through the water bath 4 to the copying rollers 5, 6 and 7 The Specification of Letters Patent.

driving movement is imparted to the roller 7 and when the latter is pressed in the known manner against the roller 6 rotation is transmitted by friction to the rollers 5 and 6.

Between the table 8 and the paper 1 there is a constantly revolving shaft 9 and a parallel shaft 10 is driven through the intervention of gear wheels 9 and 10 (Fig. 2).

On the shaft 9 is fast a grooved friction,

wheel 11, and on the shaft 10 is mounted a loose wedg-e-shaped wheel.12 formed with a peripheral recess 13 which in the position shown in Fig. 1 interrupts the conection between these wheels. The wheel 12 is held in this position through the intervention of a feeler-arm 14 on the sleeve 12 of said wheel 12 (Figs. 2 and 4.) The feeler rests upon the paper'l in the path of perforations 15 therein. When a perforation advances beneath' the feeler, the latter enters same and so causes the wheel 12 to turn until its Wedgeshaped circumference engages in the groove;

of the wheel 11 and is then rotated by the latter. The wheel 12 turns-until it is again in the position shown in Fig. 1 when the feeler 14 comes to rest on the surface of the paper, until it subsequently drops into another perforation. a

the shaft 10 is fixed a chain wheel 16 which by a chain is connected with a chain wheel 17 loose on the shaft 18. (Fig. 1). A further chain-drive 20 imparts motion in the known manner to a wheel 19 loose on the shaft of the copying roller 7. From here another chain-drive 20 passes to the roller 21.

The chain wheel 17, loose on the shaft 18,,

is connected with a grooved wheel 22 (Fig.

3). :On the shaft 18 is fixed an arm 23 which and 3). 7

When the feeler 14 drops into a perforation 15 of the copying paper, and the loose wheel 12 is taken around by the constantly rotating grooved wheel 11 in the manner previously explained the feeler-arm 14 causes the bellcrank 29, 30 to stving and to the shaft 18 with it. The shaft 18 lets the feed device 31 make one revolutionand this mo-- tion may be utilizedto, set in motion ,any
