Abstract: 9246. Burg, H. April 21. Type, setting.- Machine for detaching from an endless line of types or matrices provisional lines of approximately equal length, to be subsequently justifled by hand or by justifying- apparatus. The machine is arranged to detach the line at the nearest word or syllable within the desired length of line, and in the latter case a hyphen type is retained at the end of the line, such types being set up between each two syllables towards the end of each line, and all being subsequently ejected except that which may happen to constitute the line end. Figs. 1 and 2 show one form of machine in side elevation and in plan respectively. The endless line of type is assembled in a channel between the walls 1 and 2, such channel having a slot along the bottom through which project the bottom extensions 21, 22, 92 of the hyphen types, spaces, and end types, the latter being special types used at the end of short lines which are to terminate paragraphs. The types 9, fed in succession from a perforated strip or other composing-machine, pass down the shoot 8 and are forced into the channel by the friction-wheel 7. As the endless line proceeds along the channel the provisional hyphen types, which may be set up between each two syllables but need only be used towards the end of each line, are ejected in the following way:-When the projecting ends 21 of a hyphen type press against the pair of levers 27, which lie in their path but are clear of the shorter projections 22 of the spaces, the catch 29, 33 is released, and the spring 24 draws forward the slide 20, the hyphen type being forced by shoulders on the levers 27 into the slot 34 and thence discharged from the machine. The slide 20 is automatically returned by a friction clutch to its normal position. The action of the ejecting-device is so rapid that the relatively slow movement of the endless line during its action is immaterial. The detaching of individual lines is effected as follows:-An abutment 51 on the slide piece 17 bears against a tooth 53 on a lever 54, 56. A spring 50 tends to urge the slide piece to the left. When the advancing end of the line of type contacts with the lever 56, the slide 17 is released and moves towards the left. The pin 49 no longer holds back the rod 44 with its hooks 47, and the said hooks enter the path of the type, and as the slide 17 advances contact with the projections of the first space or hyphen type they meet and break the line at that joint. The action of the spring 50 is supplemented by the friction roller 59, which contacts with the friction surface 61 and draws the slide 17 towards the left until the end 95 of the loose doubly wedge-shaped rod 65 comes against the abutment 66. The result is to release the hinged friction surface 63 and depress the similar surface 62 upon the friction-wheel 60, which immediately draws back the slide piece to its normal position. At the moment that the hooks 47 pass the hyphen type-ejecting device, it is necessary that it be thrown out of action, in case they are carrying a hyphen type, which will then constitute the end of a line. This is effected by the bell-crank lever 71, 72, which holds back the slide 20 when the pin 68 on the slide 17 comes in contact with the detent lever 69. Adjustments are provided in connection with the slide piece 17 to allow lines of any desired length to be detached. By means of a special clutch mechanism, as soon as the line has been shifted to the full extent of the travel of the slide piece 17 the slide 18 advances, and the pawl 79 carries the line further on into the galley 11, provided with channels 15 for the reception of the detached lines. It is necessary that the slide piece 17 be released whenever an end type, terminating a paragraph, passes the hooks 47. This is effected by levers 94 actuated only by the end types 92 and operating the detent of the slide piece 17 whenever an end type pushes them outwards. A spring-actuated lever 102, 103, rapidly oscillated by the revolving eccentric disc 104, lifts the spaces, hyphens, and end types as they enter the galley, against the bottom of which they would otherwise strike. Modifications are described in the ejecting-apparatus for hyphen types. A rapidly-acting pusher may continuously tap against the type proceeding past it in the endless line, and transfer the hyphen types into a slot shaped so that they alone can pass, or cylindrically-shaped hyphen types may be ejected vertically from above or below in a similar manner, a pair of friction rolls seizing the partially-ejected type and drawing it out of the line. When ejected upwards, a pair of endless belts may be used to carry the hyphen types to an assembling box or channel. A modified device for detaching short lines terminating paragraphs consists in the use of end types having recesses formed in one side. Rapidly-acting feeler-operated levers release the detent of the above-described slide piece 17 whenever the feeler enters a recessed type. Figs. 18 and 19 show in side elevation and plan another form of machine. The lines are detached by the grasping-projections 47<1> of spring-controlled levers 44', carried on the slide piece 17<1> and normally held back by the pin 156. The slide piece is urged to the left by the cord 157 and weight 158, but is caught by the detent 161, 162. Another slide piece 167 carries a lever 164 locked by a catch 181 and in contact with the advancing end of the line of type. A pin 168 on the slide piece 167 knocks up the end 169 of the detent lever 160 when the line has advanced a certain distance, and the slide piece 17<1> detaches a line and carries it to the left. Both slide pieces are returned to the normal position on reaching the end of their stroke, the one by the action of a clutch 87<1> and cord 163, and the other by the weight 166. Hyphen types are pulled out into the channel 185 by the hook-shaped levers 27<1> pivoted on the slide 20<1> and provided with detents 29', 33<1>. A special clutch device is provided to return the slide 20<1> to the normal position. The slide 18<1> with pawl 79<11>, used to convey the line still further to the left, is operated when the pin 171 on the slide piece 17<1> comes in contact with the lever 172, which operates its detent. The slide is returned to the normal position by a clutch similar to 87<1>. In order to register the number of spaces in each line with a view to subsequent justification, a slide piece 20<x> is employed, which makes one stroke whenever a space passes the downwardly-projecting plate 192 on the detent lever 27<x>. The measurement of the length of the line, also necessary for subsequent justification, is effected by the use of an abutment 204 locked in position in the type-channel at the time that the slide piece 18<1> is moving to the left. The line comes to rest against this abutment, and a lever 214 pressing against a stud 213 on the slide piece 18<1> takes up a position depending on the length of the line and actuates suitable mechanism in the justifying-apparatus.
