ERWIN EHRI-IARDT, 0F PANKOW, NEAR BERLIN, GERMANY, ASSIGNOR TO SIEMENS & HALSKE, A. Gr., 0]? BERLIN, GERMANY, A CORPORATION OF GERMANY.
APPARATUS FOR PRODUCING COMBINATIONS OF HOLES IN PAPER BANDS.
To all whom "it may concern:
Be it known that I, ERWIN EHRI-IARDT, a subject of the German Emperor, and residing at Pankow, near Berlin, Germany, have invented a certain new and useful Improved Apparatus for Producing Combinations of Holes in Paper Bands, of which the following is a specification.
The subject-matter of the present invention is an improved method of making combinations of holes in paper bands by means of punches which are operated electromagnetically.
When making combinations of holes in paper bands moving at a certain speed, it is necessary to press the punches which produce the holes through the paper bands as abruptly as possible and at the same time powerfully, in order to produce sharply defined holes and to prevent the band from being torn.
Now an important object of the present invention is to provide a method which meets these requirements. In accordance with the invention short, powerful rushes of current, which are produced when one or more condensers are charged and discharged, are used for producing holes in the paper band which is unrolled from a device at a uniform velocity. The employment of condensers proves so suitable that combinations of holes which are free from objection are obtained at a high velocity of the paper band.
As compared with the possibility of producing the holes directly by means of punches moved by hand, the present method has the advantage that the hand only determines the interval of time between the individual rushes of current, Whereas on account of the condensers these rushes of current take place at a velocity which cannot be obtained by means of the hand.
A special case of the invention would be given by the mentioned method being used for producing Morse characters. As a particular instance where this method may be used to advantage, the producing of Morse characters on paper strips may be mentioned. Every operator acquainted with the Morse alphabet can therefore produce perforated bands on an apparatus constructed according to the above method, and these bands can then be transmitted farther in the Specification of Letters Patent.

sender at a high speed. By arranging a recording device, a control in the Morse text can be obtained in addition on the perforated band. Even an inexperienced staff of operators is able to produce perforated bands which can be employed for high speed telegraphy.
In order that the invention may be clearly understood, reference is made to the accompanying drawing in which apparatus for executing the method is represented diagrammatically by way of example, and in which:
Figure 1 is a diagram showing one arrangement of apparatus suitable for the above mentioned special case, whereas Fig. 2 shows part of a paper band which has been perforated by such apparatus.
Referring to the drawing, a and a represent the two punching magnets which press holes by means of punches I), b in the paper band 0 which is passed at a uniform speed between the punches and their magnets, which holes are at different distances from one another according to the difference in time between the movements of the two punches. These distances measured in the direction in which the band is moved correspond to the dot and dash of the Morse code, so that, for example, the combination 00 shown in Fig. 2 denotes a point, whereas the combination 3 denotes a dash. The punches are operated preferably by means of a Morse key (Z in the following manner: When the key is depressed to close the contact c, the condenser g is charged by battery 7". The charging impulse instantaneously energizes magnet c and thus punch Z1 is instantaneously operated. l/Vhen the key is released, it will close the contact at e and the condenser will be discharged, the discharging impulse energizing magnet a and thus instantaneously operating punch b. Inasmuch as the characters of the charging and discharging currents are impulses of very short duration, the electromagnets will be instantaneously energized and again be deenergized and thus the punches will be only instantaneously operated, whereafter they will return to their normal position. As the paper band 0 is moved uniformly in the direction of the arrow between the magnets and their punches, the holes are produced at the different distances w and y ac-.
cording to the interval of time in each case between the contacts 0 and a being contacted by the key d.

Means for roducing perforations in moving paper strips or the like, comprising a plurality of electromagnets, each having independent perforating means operated by it, means for energizing and deenergizing the magnets successively at predetermined time intervals, the de'energizing of each magnet following instantaneously its energizing independently of the action of the operator.
2. Means for producing perforations in moving paper strips or the like, comprising two electromagnets, each having independent perforating means operated by it, means for energizing and deenergizing the magnets successively at predetermined time intervals, the deenergizing of each magnet following instantaneously its energizing independently of the action of the operator.
3.

4. Means for producing perforations in moving paper strips or the like, comprising a condenser, a direct current chargingand a discharging circuit for said condenser, an electromagnet in each of said circuits having perforating means operated by it, and means for alternately connecting said condenser with either circuit at predetermined time intervals, the deenergizing of said magnets following instantaneously the energizing by the charging and discharging current impulse of said condenser independently of the operation of said connecting means.
5. Means for producing perforations in moving paper strips or the like, comprising a condenser, a direct current chargingand a discharging circuit for said condenser, an electromagnet in each of said circuits having perforating means operated by it, and handoperated means for alternately connecting said condenser with either circuit at predetermined time intervals, the deenergizing of said magnets following instantaneously the energizing by the charging and discharging current impulse of said condenser independently of the operation of said connecting means.
6. Means for producing perforations in moving paper strips or the like, comprising an electromagnet having perforating means operated by it, a condenser, a direct current source for charging said condenser, and means for connecting said magnet, said condenser and said source in series for energizing and deenergizing said magnet, the deenergizing following instantaneously the energizing independently of the time interval said magnet remains in circuit.
