Specification of Letters Patent.

Application filed @etober ta, 19M. Serial No. 866,251.

To all whom it May concern Be it known that We, WILLIAM llnoin and WILLIAM EVA, subjects of the e g of the United Kingdom of Great Britain and Treland, and residing, respectively, at 3 Montpelier Terrace, Edinburgh, in the county of Midlothian, Scotland, and 92 Comely Bank avenue, Edinburgh aforesaid, have invented new and usefulllmprovements in or Relating to Type-Bar-Making Machines, of which the following'is a specification.

The present invention relates to improvements in machines of the Mergenthaler type, commonly known under the trade mark Linotype, for making type bars or socalled slugs, and as illustrated, for example, in United States Letters Patent to U. Me genthaler, No. 436532, In them a vertically reciprocating organ, known as the first elevator and carrying the composed lineof matrices descends to hold the said line in the casting position, and the mold for the body of the slug to be cast against that line, is moved up .to the latter and forced into metal-tight contact with it. Molten metal is thereupon injected into the mold. Now the descent of the saidelevator and the injection of the metal are sufficiently independent of each other for that injection to take place, in spite of the descent being incomplete, in which case the metal is discharged into the adjacent operative parts of the machine and causes considerable mischief there. To prevent this, there is a socalled vise automatic stop bar so arranged between the said elevator and mold as to require displacement by a completed descent of the former, such displacement being a condition precedent to the said movement of the mold being'followed byan injection of metal, all as shown and described in the above mentioned-Letters Patent. A similar mischief "occurs if the composed line is so deficient in matrices orspacers, that the actof thickening-the latter to the maximum an act necessaryto effectthe justification of the, line and performed during the time that that line is held by the elevator in the socalled vise leaves intervals between the ad jacent e ements of the line. One of thejaws of the vise is fixed, and the other movable away from it, but the maximum distance through which'theflatter can be moved is dictated by the standard length of the slugs. To prevent the last-mentioned mischiefthe' metal injecting pump is held out of action by a so-called pump stopping lever which can be disengaged only by the movable jaw, and by that" only when the jnstification of the hue has moved the said jaw through the distance above mentioned, see for instance United States Letters Patent No. 659865 to Gr. A. Bates.

Each of the above described mischiefpreyenting devices is returned to its normal position by respective and suitable means such as a spring. But either or both of them may stick instead of being properly re- "and is then raised till it is on a level with the first elevator, when it releases a so-called delivery carriage which transfers the line from the assembler elevator into the first elevator and also efieots the starting of the machine,

whereupon the first elevator is automatically started on its descent tothe casting position. Thus, if the assembler ele-' vator is stopped before it completes its rise, the-first elevator cannot so start, or in fact the machine itself.

The just-mentioned means of the inven tion consist of a stop which is pushed into the path of the rising assembler elevator, so

as to stop the latter before it releases the delivery carriage, which stop is moved into the said path by a complete descent of the first elevator acting through the depression of the vise automatic stop bar or the disengaging movement of the pump stopping ever.

The accompanying drawings show a pre-- ferred constructional form of the invention.

Tn them Figure l is a front elevation, and

Fig, 2, a side elevation from the right of Fig. l but omitting the assembler elevator.

l is the assembler elevator in the position in which it is stopped by the stop 2 whenthe -latter is-pushed into the path of that ;elevatoi"s rise.-' This stop consists of a horioperating with only the front of the assem;

bler elevator, or bifurcated as shown in Fig. 2 to coiiperate with both the front and the back of it.

5 is the so-called viseframe wherein is slidably mounted the vertically movable first.elevator 5 which receives the composed line from the assembler elevator 1 and presents it to the mold for the casting operation.

6 is the vise automatic stop bar freely mounted in the vise frame 5 and adapted to be engaged by the screw 6 carried bythe first elevator.

7 is the front end of the pump stopping lever. The figures show both these parts 6 and 7 in their normal positions, i. 0., those from which they are respectively depressed by the descent of the first elevator and moved to the r'ightby the movement of the movable jaw, and into which positions they are returned by the respective returning means. Neither the movable jaw, nor the returning means, are included in the drawin is a lever of the first class fulcrumed at 9 on the front of the vise frame 5, so as to work in the vertical plane and having its left-hand end pivotally connected directly or indirectly through a rod 10, to the bar 6. Its opposite end is continued past the vise frame 5 to engage with a bell crank lever 11 fulcrumed at 12 on the end of the vise frame 5. Thislever has the front end of its horizontal arm maintained in contact with the right hand of the lever 8 and a cam surface 13 on its vertical arm with a horizontal rod 14, by a spring 15 pulling on the said horizontal arm from a fixed point on the vise frame 5. This rod 14 is carried in a horizontal position on the right hand of, and in the path taken by the pump stopping lever 7, by a bracket 16 fast on a vertical lever 17 fulcrumed by its bottom end and below .the rod 14 at 18 on the channel 4, and having. its top end loosely connected, as by a stud and slot device 19, with the stop 2. The latter and the lever 17 have suitable returning devices such as springs 20 pulling from fixed points on the said channel 4. The rod 14 is adjustable in its bracket 16 to and from the lever 7 by a screw thread and lock nut device 21, and the angle which the two arms of the lever 11 make with each. other, by a device 22.

The invention acts if either bar 6 or the lever 7 is not returned to its normal position after the respective depression or disengagement has been eifected, and, also, if neither has been efiected. Thus, as the first elevator descends on to the top of the vise frame 5, it depresses the bar 6, and the latter, throu h the lever 8, makes the cam surface 13 raise the rod 14 and, through the lever 17, move the stop 2 into the upward path of the assembler elevator 1, as indicated by the dotted lines in Fig. 1, thereby stopping it before it completes it rise and, consequently, preventing the first elevator starting. The stop 2 remains in its stopping position until the bar 6 is returned to its normal position. Also, as the front end of the lever'7 is moved to the right to disengage the said lever from the metal-injecting pump, it pushes the rod 14 to the right (pro-' vided, of course, that the depression of the bar 6 had not already done it), and acts on the stop 2 in the same way and through the same means as the engagement of the surface 13 with the rod 14, with the same efiect upon the assembler elevator 1 and the first elevator, the stop 2 remaining in its stopping position until the front end of the lever 7 is returned to its normal position. As soon as either bar '6 or lever 7, whichever hadrocked the lever 17, or both (if both are c0ncerned in that rocking), ar'e returned to nor-v mal position, the springs 20 return the lever 17 and the stop 2 to theirs.

Having described our invention, we declare that What We claim and desire to secure by Letters Patent is 1. In a typographical machine, the combination of anautomatic machine-stop-device, and means whereby the abnormal operation of said device will prevent the starting of the machine.

- 2. In a typographical casting machine,

4. In a typographical casting machine,

the combination of a. pump stop movable automatically to'and from its normal position, and means for preventing the starting of the machine when said device is in abnormal position.

5. In a typographical casting machine, the combination of a carrier to presentthe composed line to the casting mechanism, a pump stop device adapted .to be moved from its normal position by the justification of the line, and means to prevent the presenting movement of the carrier unless said device is in its normal position.

nicest/a 6. In a typographical composing and casting machine, the combination of a movable assembler wherein the line is composed, a pump stop device, and means controlled by said device for arresting the movement of the assembler.

7.. In a linotype machine, the combination of the first elevator, the vise automatic controlled thereby, and means whereby the abnormal operation of said vise automatic will prevent the starting of the machine.

8. In a linotype machine, the combination of the movable assembler, the first elevator to receive the composed line therefrom, the vise automatic operated by the first elevator, and means controlled by the vise automatic for arresting the movement of the assembler. 4

9. In a linotype machine, the combination of a movable assembler, the first elevator to receive the line therefrom, the vise automatic movable to and from normal position under the influence of the first elevator,

a movable stop device to arrest the movement of the. assembler, and connections whereby the stop device will be moved to active and inactive position as the vise automatic is moved from and to its normal position, respectively, for the purpose described.

10. in a linotype machine, the combination of the movable assembler, a movable locking device therefor, a pump stop device movable to and from its normal position, and connections whereby the movement of the stop device from and to its normal position efiects the movement of the locking device to and from its active position, respectively.

In witness whereof we have hereunto set our hands in the presence of two witnesses.

LLIAM INGLE. WILLIAM EVA.
