ASSIGNOR TO MERGENTHALER LINOTfiE- COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

To all whom it may concern Be it known that I, BRUNO BLOCH, a subject of the German Emperor, residin at 23 Chausseestrasse, Berlin, N. 4, in the mpire of Germany, have invented new and useful Improvements in Typographical Machines, of which the following is a specification.

The present invention relates to an arrangement, by means of which machines operated manually through a key board, especially matrix composing and line casting machines may be driven at times mechanically by means of a perforated strip. It has already for this purpose, been proposed to release electrical contacts by means of a perforated strip and thus operate upon the keys of matrix composing machines through the mediation of electromagnets. This arrangement however has the disadvantage of bein extremely complicated and sensitive and therefore unreliable. According to the present invention a mechanism independent of the machine itself, and controlled by a perforated strip of paper is provided, to be applied at will to the machine so as to effect a mechanical operation of the key mecha-' nisms. It may operate upon any members of the latter.

Referring to the drawing: Figure 1 is a vertical section taken through the key board mechanism of a linotype machine, and showing my invention applied thereto; Fig. 2 is a side elevation, partly broken away, of my improved mechanism; Fig. 3 is atop plan view of the parts shown in Fig. 2; and Fig. 4 is a detail view. 1

a are the keys by which in the known manner through mediation of the escapement rods 6, the escapements 0 can be operated.

According to the invention, and in a covering box not shown in the drawing, a series of levers d is suitably fulcrumed on the axis 6, their front ends projecting out of the covering box, so as to be able to engage notches n in the escapement rods b. Each of these levers d has a releasing pin 7. The perforated strip of paper g is passed around a guide roller is, and overthe the pivoted levers d, so as to locate its perforations above the releasing pins f of the levers. This strip has the width of the key board and is moved intermittently by a pawl and ratchet arrangement 0 operated by a came on the driving shaft p of the machine. The

strip is moved along by the driven roller in the known manner by means of sprocket ration 1n the edges of the strip. The levers d are pulled upward by the springs b. so as to bear against the perforated strip. In

order to prevent the latter from being pushed away, a counterpart i is provided which has holes at the parts opposite the pins f, into which holes these pins can enter, if the strip 9 happens to be perforated at a corresponding place. Durin each advance ofthe perforated strip 9 al levers d are once moved upa'nd down by the cam disks 70 arranged at the opposite ends of the guide roller k for the strip. To this end, a suitably-guided bar m is provided,.extending over the levers d and having upwardly proecting studs m engaging the toothed shaped cams on the cam disks k.

engaging continuous rows of perfo- The improved mechanism works as follows :--The perforated paper strip advances intermittently to the extent of one section.

Each section has ahole in a position to cor-' respond with the letter to be used. During the movement of the strip 9, all the levers (Z are held out of contact with the perforated strip by the action of the cam disks in on the bar m. After the advance of the strip g, the studs on the bar on enter depressions of the cams k, so that the levers d are able to move upward, and the lever whose pin 7 is then opposite the hole in the strlp g is raised by the spring 72. to such an extent as to lift the escapement rod 7). Each escapement rod is formed with a notch 11. of such dimensions as to allow the corresponding lever d when not thus released to move under the action of the cams k without imparting movement to the rod. Y

The whole casing within which the releasing device is arranged is made so as to be easily aflixed to the machine to be operated,

so that the machine may at will be changed from a hand machine into an automatic mama chine.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. Alternative perforated strip mechanism 105 for operating a machine fitted to be operated through a manually operated key board, consisting of a perforated strip, means for advancing it with a step by step.1 motion; releasing studs moved toward t e said strip after each advance; means for so-moving them and causing one of them to ass through the respectively opposite per oration; and means by which the movement of that passing through actuates the respective key mechanism of the machine.

2. Alternative perforated strip mechanism for operating a machine fitted to be operated through a manually operated key board, consisting of a perforated strip; means for advancing it with a step by step motion; releasing studs moved toward the said strip after each advance; means for so moving them' and causing one of them to pass throughthe respectively opposite per. foration; means for moving all the studs away from the strip before each advance of the latter; and means by which the movement of that passing through actuates the respective key mechanism of the machine.

3. Alternative perforated strip mecha-' nism for operating a machine fitted to be 0perated through a manually operated key board, consisting of a perforated strip;

means for advancing it with a step by step motion; releasing studs moved toward the said strip after each advance; levers carrying the said studs; means for so moving the said levers and studs and causing one of the studs to pass through the respectively opposite perforation; means by which the respective lever operates the respective member of the keymechanismsynchronously with the passage of the stud through the perforation; and means for returning the levers without affecting the unoperated members of the key mechanism.

4. Alternative perforated strip mechanism for operating a machine fitted to be operated through a manually operated keyboard, consisting of a perforated strip; means for advancing it with a step by step motion; releasing studs moved toward the said strip after each advance; levers carrying the said studs; a frame supporting the said levers and oscillated vertically by the strip feeding means; means for so moving bination of a series of escapement actuatingv the said levers and studs and causing one of the studs to pass through the respectively opposite perforation; means by which the respective lever operates the respective member of the key mechanism synchronouslv with the passage of the stud through the perforation; and means for returning the levers without affecting the unoperated members of the key mechanism.

5. In a typographical machine, the comdevices, a corresponding series of operating members connected therewlth and each pros with the releasing pins and permit the operation of one or another of the actuating devices by its corresponding operating member, according to the location of the perforation in the strip.

7. In a typographical machine, the combination of a series of escapement actuating devices, a corresponding series of operating members therefor each provided with a releasing pin, means tending to'operate all of said members simultaneously, a perforated strip mechanism to cooperate with the releasing pins and allow one or another of said members, to operate the corresponding escapement actuating device, and means for returning the active member to its original position after its operation.

8. In a typographical machine, the com bination of a series of escapment actuating devices, a corresponding series of members tending constantly to operate said devices, releasable means for holding the members against operation, and a perforated strip mechanism to control the operation of said members when released by the holding means.

9. In a typographical machine, the combination of a series of escapement actuating devices, a corresponding series of operating members therefor each provided with a releasing pin, a perforated strip mechanism movable step by step past the operating members and adapted to cooperate with their releasing pins and permit the operation of one or another of said members, and means for moving said operating members toward and from the strip as it is advanced to subject their releasing pins to the action I BRUNO BLOCI-I.
