Abstract: 27,799. Elektrizitõts-Akt.-Ges. vorm. Schuckert & Co. Dec. 17, 1906, [date applied for under Patents Act, 1901]. Type, setting.-Relates to machines for making perforated strips for controlling type-composing and type casting and composing machines. By the depression of keys 1, any one of a series of combination plates 4 may be moved into the path of a striker 6 actuated by an eccentric 13, which is caused to make one revolution by a friction clutch device released by the plates 4. Projections 14 on the plates 4 depress a series of bails 14<a>, to which are connected the punches 14<b>. An arm 25 of the striker 6 returns the operated punches and also actuates a feed-hole punch 24. Beneath each of the plates 4 is located one of a series of vertically-sliding pins 5 of varying length carried by two blocks 26, 26<a>, either of which may be brought into use by means of a handle 41. The pins 5, when depressed by the plates 4, actuate bails 29<b> and levers 29<a>, by means of which one of a series of stepped stops 29, Fig. 3, is raised to an extent depending on the length of the depressed pin. The bails 14<a> actuate a bar 42, which, by means of a friction clutch, causes a shaft 46 to make one revolution. A cam on the shaft 46, acting through a lever 55, thereupon moves a sliding rack-bar 39 into contact with the projected stop 29. The rack-bar 39 is then drawn down into gear with a unitswheel 27, from which a detentlever 40 is simultaneously withdrawn. The bar 39 then moves back into contact with a fixed stop 28, whereby a rotation proportional to the width of the character is imparted to the wheel 27. The justifying-perforations for the line are selected by a drum 61, Fig. 1, having various combinations of perforations on its surface. The drum is frictionally engaged by a constantly rotating member, and its movement is controlled by a pin 60, which is engaged by an arm 59 on the units - wheel shaft. The perforations in the drum are engaged by a series of pins 17<d>, carried by a bar 68 and connected to spring-pressed levers 17<c>, which actuate the punches. The justifying-signal consists of two consecutive sets of perforations, the second set being obtained by moving the dram 61 along its shaft. The levers 17<c> are released, to enable the justifying-perforations to be formed, by cams on a shaft 62, which makes one revolution upon the depression of the justifying-key. A galley signal is made simultaneously with the first part of the justifying-signal. The units-wheel 27 and drum 61 are returned to the zero position by a cam 64, Fig. 3, on the shaft 62, which releases the detentlever 40 and interposes an arm 66 in the path of a stop 67 carried by the units-wheel. Justification is effected by varying only a limited number of spaces in the line, the bar 68 which carries the pins 17<d> being advanced a step at each actuation of the space-key. In order to render the spaces as far as possible uniform, those that are not varied for justification are increased in width. This is effected by means of a special combination plate 4, which after the number of variable spaces has been exceeded, is coupled by the action of the bar 68 to the plate 4 corresponding to the space-key.
