Specification of Letters Patent.

Patented Dec. 1%, 1915.

Application filed April 16, 1913. Serial No. 761,427.

To all whom it may concern:

Be it known that I, HEINRICH DnnwnLL, sub ect of the German Emperor, resldmg at Charlottenburg, Germany, have invented v new and useful Improvements in Type-Setting Machines, of which the following is a specification.

The principal object of the present invention consists in means for automatically interrupting the actuation of an automatically operated composing machine in case of trouble occurring in the assembling of matrices or types, the assembling device being obstructed for instance. For this purpose a stopping device is actuated if a movable member, the movement of which corresponds with the increasing length of a line of matrices or types being set up, which member may be termed as the line-controlling member, remains at rest for a certain time although a certain number of matrix or type delivering devices have been operated during this time. As,' however, certain delivering devices, for example those delivering the word separating blanks, or an e, an n or any other character whichoccurs frequently, are operated repeatedly in most every line, it is suflicient to control the stopping device by means of one of these delivering devices in' connection with the line controlling member in order to limit the number of matrices or letters possibly released after a trouble occurs until the machineis stopped.

' In the hereafter described embodiment of my invention I prefer to control the stopping device by means of the device delivering the word separating blanks into the It is supposed thattwo such blanks inserted between them. .Now, if the linecontrolling member has not moved since a certain operation of said blank delivering device and the latter is operated again, something in the machine mustbe out of order and the stopping device is therefore operated in such cases; r

In the drawings is shown an embodiment of this inventionin combination with the assembling device of the well known matrixsetting and line-casting machine of the Mergenthaler system. It is supposed that this machine is automatically operated by means of a perforated band for example in the manner described in my U. S. Letters Patents 864,519 dated- August 27, 1907 and 915,748 dated March 23, 1909, and in my copending application Serial Number 691,100, filed April 16, 1912.

Figure 1 shows the mechanical part of the device, Fig. 2 is a diagram of the electrical connections, Fig. 3 shows the device for re-actuating the composing machine, and Fig. 4 shows the switching device controlling the operating electric current of the machine.

In Fig. l the line-resistant l supporting the matrices or letters and keeping them from being thrown down, is fastened on the slide 2 which is suitably guided in the main frame of the machine. With the slide 2 is connected a rack 3 provided with small ratchet teeth on itsupper edge. Above the rack is a lever I swinging around the neckscrew 5 and bearing an easily rotatable three-armed lever 6. Acted upon by a spring 7 this lever tends to lean with its lever-arm 8 against the pin 9 011 the lever at. The lever-arm 10 of the lever 6 is pressed downward by the end of a pawl 11, which is rotatably fastened on a movable plate 12.

A spring 13 acting upon a. short arm of the pawl 11 tends to push this pawl against a pin 14 fastened on the plate 12. By means of a neck-screw 15 the plate 12 is rotatably fastened on a short lever 16 swinging around the neck-screw 17. At the upper end of the plate 12 is fastened a rod 18, which is connected with a lever 19. This lever is pivoted by a neck-screw 28 to the main frame of the machine and is connected with a releasingrod 20. This rod is rocked and the lever 19 turned in corresponding manner when a certain key, in the present case the key for releasing space-bands is struck. The device for lifting the rod 20 and for striking the corresponding key is for example fully shown and described in the drawings and specification of my U. S. Letters Patent 864,519, dated Aug. 27 1907. As described before it is advantageous to choose for this purpose the key serving for releasing and inserting the space-bands or wedge-shaped justifiers. When the rod 20 and the lever 19 have returned into their lower positions, the pawl 11 leans upon the lever arm 10 of the small lever 6, which acted upon by the spring 7 has turned during the lifting of the lever 19 and the plate 12 so far that its arm 8 touches the pin 9, while the lower arm 22 engages with the teeth of the rack 3. The lever A is acted upon by the tension-spring 23 and the platespring 24, which lies upon a projection 25 of insulating material at the end of the lever 4. The leaf-spring 24 tends to press the lever 4 down, though usually it is drawn up by the stronger spring 23, which causes the spring 24 to be pressed against the opposite contact-screw 26. If however the pawl 11 leans, as described before, upon the leverarm 10, the lever 4 is pressed downward by the stronger spring 21 operating the rod 20, and the contact between the screw 26 and the plate-spring 24 is opened. At the same time the lever-arm 22 of the lever 6 engages with the rack 3.

If the length ofthe line increases by matrices or letters being inserted, the line-resistant 1 with its slide 2 is moved in the direction of thearrow 27 and the rack 3 takes the point of the lever 22 along thereby turning the lever 6 and withdrawing the leverarm 10 from the pawl 11. Consequently the influence of the spring 21 upon the lever 4 ceases and therefore the latter is pulled upward by the spring 23 and the spring 24 touches the contact-screw 26. But if the length of the line does not change any more pressed levers operated by the two holes of the perforated register-band, which constitute the space band symbol. The pointed ends of the levers are pressed against the register-band, the other ends carrying contact-

screws

33 and 34 which tend to contact with the opposite metal pieces 35 and 36. The levers are connected with one pole of a source of current 37. The metal-piece is connected with the coil of an electromagnet 38. From there another connection 39 leads to the other electric devices ofthe machine. Over a switch-lever 40, a contact- 41 attached :to the latter, and a contact screw 42, the connection 39 is connected with the other pole of the source of current The switch-lever 40 is acted upon by the pawl 43, keeping it in its rest-position 'and'so causing the spring 41 to contact with the screw 42. If the pawl 43, constituting the armature of the electromagnet 58, is attracted by the latter, the contactis opened at means of a spring 44 acting upon the switchlever40, and the" current actuating the .composing machine is interrupted.

If

thelevers

31 and 32 enter two holes in the perforated band at the same time and cause the

screws

33 and 34 to touch the metal pieces 35 and 36, the electromagnet 38 actuates the switch-lever 45 and causes it to contact with a screw 46, thereby closing the circuit of an electromagnet 47, this electromagnet serves for inserting the spacebands. The circuit of this electromagnetcontains the screw 26 and the leaf-spring 24,

two

other electromagnets

48 and 49, actuatingthe switclrlevers 50 and 51, belonging to a shunt-circuit parallel to the contactspring 24 and the contact-screw 26. As long as the spring 24' contacts with the screw 26, a current flowing through the electromagnet 47 causes the space-band to be released. But if the

levers

31 and 32 touch their metal pieces 35 and 36 respectively, closing the circuit of the electromagnet 47, while the contact between the spring 24 and the screw 26 is opened besides the coil of 'electromagnet 47 the coils of

electromagnets

48 and 49 areenergized, the latter being now in series with the electromagnet 47 and diminishing by their resistance the current of the electromagnet 47 so as to prevent it to become operative. The

levers

50 and 51, however, are switched in this case. These levers are connected with the poles of an electromagnet 52, serving for stopping the registerband after a line has been set and for actuating the device for transporting the l1116. The operatlon of this electromagnet is fullv described in my before-mentioned copend-ing application Serial No. 691,100 filed April 16, 1912. levers50 and 51 lean against the

screws

53 and 54, which are connected with the maincircuit of the composing machine, and by means of the register-band cause the elec- In their rest positions the tromagnet 52 to beenergized when a certain perforated symbol ofthe band becomes operative. After having been switched the

levers

50 and 51 contact with the

screws

55 and 56, one of which is connected directly with the pole of the source of current 37. the otherleadi-ng to the other pole over the coil of the electromagnet 58. If the

levers

50 and 51 are switched because of the

electromagnets

48 and 49 being energized, the electromagnets 52 and '58 are directly connected 7 with the two poles of the source of current 37 and therefore are actuated. The electroinagnet 52 acts upon the device for stopping the register-band and electromagnet 58 acts upon the pawl 43, withdrawing it from the end of the lever 40. Consequently the main circuit is interrupted between the spring 41 and the screw 42. When the lever 40 begins to move the spring 41 remains on the contact screw 42 for a short time, although long enough to allow the electromagnet 52 to be properly energized and to become'operati-v'e luzfore the main circuit is interrupted. It

may be seen therefore, that the actuation of the composing machine is interrupted, e. g.

the register-band is'stop-pedand themaincircuit is interrupted, if a space-band symbol acts upon the

levers

31 and 32 while the spring 24 does not contact with the screw 26. 'For re-actuating the machine after the trouble has been removed the lever 10 must be caught by the'pawl 43. This is done by means of the device described hereafter,

The register-band is guided partly by a frame 61 rotatably mounted on the shaft 60 '(Fig. 3), as more particularly described in my before-mentioned co-pending application. The frame is lifted for introducing the register-band and then'replaced into its horizontal position shown in Fig. 3 in dotted lines. The shaft 60 has a projection 62 acting upon an angle-lever 63, 64;. At the arm 6% of-the latter is fastened a rod 65, carrying a finger 66, adapted to act on the lever 40 of the main switch. When the frame is opened, the projection 62 releases the anglelever 63, 64;, and the rod 65 moves downward on account of its weight or compelled by a suitably attached spring and by means of its finger 66 causes the'lever 40 to be caught by the pawl 43.

The Working method of the here described device can be shortly interpreted as follows: Each time the space-band key is used, the rod 18 with its pawl 11 presses upon the lever 10 or 4 and the contact between the screw 26 and the spring 24 is opened. The matrix following next to the space-band causes the contact to be closed again by pushing forward the slide 2 with the resistant 1. If suddenly there are no more matrices assemblcd into the slide because of the en.- trance being obstructed or such like, the next space-band symbol of the register-band Opens the contact and the following one stops the action of the machine. The number of matrices released from the magazine in the meantime is limited by the frequent occurring space-bands. After the trouble has been removed, the frame 61 is opened and the register-band drawn back far enough to re-set the same line. The opening of the frame 61 causes the main circuit to be closed again.

As stated above one of the frequent occurring letters like e or n can also be used for the purpose described above instead of the space-band.

The device can also be used without any essential alteration in combination with type-setting machines since in these too there is or can be applied a member, which moves with the progressing length of the line corresponding with the slide 2. Besides this movement the device requires nothing but a rocking movement of the rod 18 caused by the insertion of a special, frequent occurring type or its equivalent.

What I claim as my invention and desire to secure by Letters Patent is:
