TYPOGRAPHICAL OR SLUG-CASTING MACHINE.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed July 23, 1915. Serial No. 41,572.

To all whom it may concern:

Be it known that I, JOHN WV. GRAHAM, a citizen of the United States, residing at Hinton, in the county of Summers and State of lVest Virginia, have invented certain new and useful Improvements in 'lypographical or Slug-Casting Machines, of which the following is a specification.

My invention relates to typographical machines, such as linotypes of the original construction, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print, and then assembled in line together with expanding spacers, the composed line brought in contact with the face of a mold, the mold filled with molten metal to form a line of type or slug against the face of; the matrices, which produce the type char acters thereon, and the matrices thereafter returned to the magazine from which they were originally drawn.

More particularly it relates to that class of machines having a serles of magazines,

any one of which can be brought into operative position and locked therein, and wherein the magazines are removable and interchangeable.

My invention is embodied in the construction of the arms which guide the travel of the magazines, and in the construction of the locking device, but I do not claim the principle involved either in the housing of the magazines, the arms, or the mechanism which guides the travel of the' magazines upward or downward, to be part of this invention, as they are claimed in previous applications filed by me. The main feature of this invention, is embodied in the feature series of magazines when brought to the lowest point of operative position, which brings the uppermost magazine into operative position, are then suspended in slotted arms. The guide rollers on the lower rack rest in the bottoms of the slots in the arms and the racks and magazines are thus suspended. A supporting base can now be lowered away from the racks and magazines, and the magazines and racks are so made as to be heavier behind than in front. As the base moves downward the racks and magazines can be brought to a substantially horizontal position to facilitate the quick and easy removal of the magazines.

In the accompanying drawings I have shown my invention as an example and in a preferred way, and many changes and variations may be made therein without departing from the spirit or principle of this invention, and I wish to be understood that I do not limit myself to any form, or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings, Figure 1 is a side view of-a portion of a linotype machine having my invention applied thereto. 2 is a rear view of the forked arm A. Figs. 3 and 3 show top and side views of a rack and its magazine. Figs. 4 and 4* show front and side views of the automatic lock.

Referring to Fig. l

A is the main forked arm of the machine.

A is an arm extending back from the main arm A at each side to support the distributing mechanism.

A is a brace at each side connecting the frame of the machine with the top of the arms A. e

A shows the slots in the arms A.

A shows the holes in the arm A arranged in different vertical planes as shown to engage the lock pins.

B is the base which supports the magazmes.

B are the rollers in the base which allow the lowermost rack to move endwise on the said base.

B shows the threaded nuts which engage the screws B CC and 5 are racks whichsupport the magazines.

C shows the guide rollers on the racks.

C shows. the supporting rollers on the racks.

3 shows the stop dog in the saidracks to hold the magazines in place (see Fig. 3).

D shows the lock pins (see Fig. t)

D is the diskv which'supports the heads of the lock pins. (see Fig. l).

D is the shaft which operates ing device.

D are universal joints in the shaft D D shows a dial.

D shows a hand wheel having on it a finger D7.

E shows a hand wheel to raise and lower the magazines.

E? shows the, shaft to operate the; lowers d, rai i g mechanism.-

the lock- E shows the cross shaft connecting the two screws B.

M shows a magazine.

M shows the extended ends of the strengthening bars on the magazine M, which work in conjunction with the stop dogs C to hold the magazine in place.

In operating the machine the hand wheel E is turned to the right or left as desired, and operates the shaft E by intermeshed bevel gears. The shaft E is connected to the screws B by inter-meshed bevel gears, and the said screws are engaged with the nuts B on the base B, thus raising or lowering the magazines. To bring the magazines to a horizontal position, in order to remove a magazine or for any desired purpose, the base B is lowered until the guide rollers C of the lowermost magazine rest on the bottom of the slots A in the arms A. The base is then lowered sufiiciently to allow the magazines to tilt backward to the desired angle. The magazines as ordinarily constructed are heavier at their rear than at their frontal ends, and thus will tilt downward at the back by gravity. The arms A are made slotted to receive the guide rollers on the racks, and the said slots are made vertical above the operative position. Below the operative position the slot runs back at an angle sufiicient to allow the lowermost magazine, when resting with its guide rollers in the bottom of the slot, to tilt down at the back so as to rest on a line substantially horizontal and still allow its frontal end to rise up without interfering with the escapement channel, and so that the other magazines of the series will also come to a horizontal position and not interfere with the escapement channel.

No power raising or lowering device is shown on this machine, but it is obvious that any such device may be applied, such as any of the devices shown in the previous applications for patents on similar machines, by me. The entrance channel is hinged on a slidable block and may be moved outward without changing its upright position, but this feature is no part of this invention, being claimed in a previous application.

In operating the locking device the hand wheel D is turned to bring the finger D to the desired number on the dial D The dial 1) is numbered to correspond to the number of magazines. The disk D is made circular and the heads of the lock pins rest upon it. The disk has at a preferred point on its rim a depression large enough to receive the head of one pin. The pin whose head is located above the said depression can drop into its corresponding hole A in the arm A when the base is moved to the proper position, but the other pins resting on the thicker parts of the disk D are held out and cannot engage their corresponding holes. The pins are set in the base preferably in the form of a half circle and the holes in the arm A are set staggered across the said arm so as to be in line vertically each with its corresponding pin. The shaft D is made preferably telescoped so that it can lengthen and shorten as the base moves up or down, and the said shaft is made with flexible joints. The lock pins D are pressed in by any desired spring mechanism.

Having described my invention, its construction and operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:
