Abstract: 14,637. Wise, W. L., [Buckingham, C. L.]. Aug. 15. Punching and perforating machines for telegraph strips &c.-Relates to perforating-apparatus especially adapted for perforating telegraph tapes for the automatic transmission of messages by various codes, and adapted for receiving messages either in code or as page printed messages. The invention described consists of improvements in that class of apparatus described in Specification No. 21,548, A.D. 1896 ; reference is also made to the printing- telegraph apparatus described in Specification No. 8180. A.D. 1897, [Abridgment Class Electric telegraphs &c.]. The Specification describes perforating- arrangements adapted for morse codes and for a type-printing code with methods of varying the spacing either between the word or signs. Features are also made of the cancelling of errors by perforating, as with a series of dots, special line and space marks, and also long blank spaces or extended space marks for dividing the message into sections. This long blank space form is described in connection with duplexing, the intervals being utilized for transmitting by hand correction or other signs. The Specification further describes keyboard arrangements and indicating-arrangements for showing the number of letters perforated in a line, and also the number of lines. Fig. 5 shows an elevation of the perforating-apparatus, in which two series of perforating- magnets B are arranged face to face (those on one face only being shown). The armatures have bell-crank lever shafts stepped outwards so as to allow the vertical connecting-links y<1>, y<2>, &c. to act in clear paths. The links y<1> &c. act on bellcrank levers situated at the rear end of the punches. The punches are staggered so that one row is punched from one face and the other row from the other face, shutes being arranged for the waste to fall through. H, H<1> are the spacing-magnets ; the armatures of these magnets are arranged to act on a converging series of bars, the ends of which come into contact with stops in connection with the feed-wheel, so that the paper can be moved a predetermined distance according to the letter to be transmitted. The paper, after being perforated, is stripped from the feed-wheel by prongs at the end of an open-faced guide, to enable the record to be observed. A blade is pivoted to an upper extension to enable each message to be cut off. B<2> is the restoring-magnet for the punches, and I is the feed-wheel release magnet, normally on open circuit. D<4> is the motor for driving the feed-wheel. The feed-wheel is connected to the motor D' through a shaft carrying at its upper end a spring drum, the detached portion of which consists of a perforated plate and one half of a clutch loose on a separate portion of shafting. The upper portion of the shafting has fixed to it the spacing-device and feed-wheel ; these are provided with the upper half of a clutch arranged to slide vertically into and out of engagement with the lower half attached to the spring drum. The clutch is actuated by a hand-lever provided with a vertical locking-pin arranged to prevent the rotation of the drum when the clutch is released. An arrangement of keyboard mechanism is shown in Fig. 20, in which the keys m<1>, mounted in a detachable frame G', act on a number of stretched wires or chains connected at their free ends with a series of contact-devices h<5> arranged, when the keys are depressed, to make contact with the pins l<2>. The pins l<2> form extenions of the plates h<7> set in an insulated block h<8> or connected to the various magnets for completing the punch and feed combinations for each individual character. Hand-switches are employed for varying the feed when the spacing is to be altered for the different codes and conditions of signalling. The key levers are set in a frame provided with longitudinal and transverse divisions for the keys, and are pivoted to a common bar m<20>. Rub-out and spacing keys are also employed. In the case of messages for printing-receivers, the message may be sectioned and divided into lines, a letter indicator W and a line indicator X being attached to the apparatus. The letter indicator is provided with a hand setting-device, or is operated by an escapement s<9> acting on the wheel z<1>. The escapement is operated by a transverse bar s<7>, whenever a signal key is depressed. The indicator also carries a notched di-c L, in which a lever p<4> engages whenever the complement of letters forming a line has been perforated. This lever at the same time operates the line indicator, and places a locking-bar under the keys so that no further signals can be perforated until the line space key has been operated by which the various parts are released.
