SPECIFICATION forming part of Letters Patent No. 784,267, dated March '7, 1905.

Application filed September 1,1904. Serial No. 222,998.

To all 103mm, 2'1- m-(ty concern.-

Be it known that I, LUTHER L. KENNEDY, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Im- 5 provement in Linotype\/Iacl1ines,of which the following is a specification.

This invention has reference to linotypemachines of the general character represented in Letters Patent of the United States No.

436.532. In these machines metal matrices representing individual characters are stored in a magazine, from which they are released one at a time in the order in which their charactors are to appear in print, the matrices,

together with expansible spacers, being delivered successively into an assembling mechanism wherein they are assembled or composed in lines, each line being thereafter presented momentarily to the face of a mold to form relief characters or type on the edge of a slug therein, after which the line is raised to the top of the machine and the individual matrices returned through a distributing mechanism to the magazine-channels from which they started. After the matrix-line is composed in the assembler the latter is raised for the purpose of presenting the line to a horizontal movable carrier by which the line is moved forward toward the mold.

It is of course necessary that the horizontal carrier shall return to its original or receiving position before a second line is presented thereto by the elevation of the assembler.

The object of the present invention is to pre- 3 5 vent the operator from lifting the assembler and sending the composed line forward toward the casting mechanism unless it has been composed or set out to such length that it can be automatically justified by the spacing de- 4 vices of the machine.

To this end it consists, essentially, of means for normally locking the assembling-elevator down, in combination with tripping or releasing devices connected with the assemblerslide, so that the assembler is unlocked and free to rise only when the assembler-slide is held forward by the presence of afull line of matrices therein. A tripping device is connected with the means for adjusting the assembling mechanism to set lines of differ- 5 ent lengths, so that the act of adjusting the machine for any given measure or length of line also effects the adjustment of the tripping device.

As all the other parts may be of ordinary construction, I have confined the drawings herein to those parts to which my invention is immediately related.

Figure 1 represents a front elevation of the assembling mechanism, the assembling-ele- 6O vator, and adjacent parts. Fig. 2 is a horizontal section on the line 2 2, Fig. 1.

Referring to the drawings, H represents an inclined belt which receives the matrices successively from the magazine and delivers them downward over a guiding-surface to a position in front of a rotary star-wheel 7L3, by which they are pushed forward successively side by side into the horizontal channel or groove in the upper end of the assembling- 7 elevator I. The matrices Z are sustained, as usual, in the elevator by horizontal shoulders therein.

As the composed line is increased in length by the addition of matrices and spacers there- 7 5.

to its advance is resisted, and it is held in compact form by the yielding finger or resistant J, carried by a horizontal slide j, guided in the main frame and known as the assembler-slide. This slide is urged constantly to 30 the right with moderate pressure by a spring or weight, as usual, and as it advances step by step it will be arrested and held until the composition of the line is completed by the usual brake or detent. 5

The machine is adjusted to set a line of predetermined length by means of a stop block or slide 11, mounted in a horizontal slot in the slide j and adjustably secured by a set-screw. \Vhen the line is of the predetermined length 9 or of such approximation thereto as to forbid the insertion of the matrices for another word or syllable, the stop 1', which sounds an alarmbell, as usual, encounters a fixed stop on the frame, thereby arresting the advance of resistantj, whereupon the delivery of matrices to the line is stopped preparatory to sending the line forward to the mold.

The assembling-elevator I is mounted, as usual, to slide vertically in the frame and conthe assembler is raised and the composed line carried upward between the depending arms of the transfer-carriage L L, which then moves horizontally to the left, carrying the line toward the mold. When the line is lifted by the elevator, it is carried clear of the resistant J, and the assembler-slide immediately moves to the right, returning the finger J to a position near the star-wheel preparatory to the composition of the next line.

The foregoing parts correspond to those which bear like letters in Patent No. 436,532

and may be of the same or any equivalent construction.

My improvementis designed to prevent the assembler I from being elevated to cause the transfer of the composed line until the line has acquired a length sufficient to insure its proper justification or elongation to the predetermined length by means of the ordinary wedge spacers or justifiers Y, forming part of the machine. For this purpose I provide an automatic dog or look M to hold the assembler down in its normal or receiving position. The locking device may be of any suitable construction, but is preferably made inthe form of a gravitating dog pivoted to the frame in position to directly engage the elevator, as shown. Whenever the elevator is lowered to the receiving position, this dog engages automatically to prevent it from beinglifted.

For the purpose of disengaging the dog and releasing the elevator when the line has acquired the proper length I mount in the assembler-slide y'a longitudinal rod N, having one end connected directly or indirectly to the adjustable stop-block and the opposite end in position to encounter the dog. This rod is carried forward with the assembler-slide as the matrix-line is elongated, and the parts are so proportion ed that when the line reaches the proper length the rod N will encounter the dog and push it out of engagement, thus leaving the elevator free to rise. When the elevator rises, the assembler-slide retreats to the right, carrying with it the rod N and releasing the dog M, so that the assembler is automatically rel'ocked when it is lowered. The assembler cannot be again elevated until the second line has reached the proper length, when the dog will be disengaged as before.

Inasmuch as the tripping device is connected to the stop 2', which controls the travel of the assembler-slide and the length of line composed, it follows that the adjustment of the stop 2' to set the machine to any given length of line also serves to adjust the tripping device to correspond with the new measure or length of line. The essence of my invention in this regard consists particularly in combinperforations to receive the stud ing with means for sending the composed line forward, and ad ustable devices for controlling the length of the line, intermediate connecand arrangement without departing from the method of operation herein described or passing beyond the limits of my invention.

v In operating the machine the matrix-line first composed in the assembler is usually of less than the final length, justification by the wedge-spacers occurring after the composition is completed. This is because the line as composed is freq uentlyof such length that the remaining space allotted will not admit the matrices for another word or syllable. The average space remaining to be filled for justification will depend to some extent on the final length or measure of the line and on the size of the type-faces and matrices employed. It is usual to set the stop device 71 to arrest the finger J before the matrix-line has reached the printing length or measure.

I prefer to connect the rod N ad justably with the stop 2', as shown in the drawings, or in any other suitable manner. tion shown the stop 2' is divided vertically and its forward end j secured to the trip-rod N and adjustably connected to the main portion 2' by a flat spring 7' having a series of on the part 2'. These connections admit'of the rod being set forward and backward in relation to the stop 2' so that the tripping action will occur sooner or later.

It will be understood that the adjustable connection between the rod N and the stop is not of the essence of the invention and is not a necessary feature and also that any suitable adjustable connection-may be employed.

The assembling-elevator, assembler-slide, and the means for delivering matrices thereto constitute jointly what is commonly known as the composing or assembling mechanism, while the adjustable stop for the assembler-slide is a means for determining the length of the composed line.

What I claim as my invention is 1. In a linotype-machine, the combination of a matrix-assembling mechanism, adjustable means for determining the length of the composed line, and means connected with the latter to prevent the transfer of the composed line until it has acquired the predetermined length, whereby the adjustment of the machine for a line of any given length automatically effects the corresponding adjustment of lthe means for preventing the transfer of the 2.
