nnrrsn STATES CHARLES E. OF ALAIVIEDA, CALIFORNIA.

TYPE-BAR-CASTING MACHINE.

Application filed February 7, 192-3.

To all whom it may concern.

Be it known that I, CHARLES F. Weeks, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Type-Bar- Casting Machines, of which the following is a specification.

My invention is an improvement in linotype machines.

In casting large letters, that is, fortyeight point, on a linotype machine it has been necessary to install av very elaborate and expensive mechanism, and also change the mold on the machine.

Vith my invention. the same mold and general mechanism is employed, the only change in the machine being that a portion of the vise is removably attached and upon its removal the wider slug with the large letters can pass between the knife block and the vise.

In the drawing in which my invention is illustrated, I have shown it as applied to the Mergenthaler linotype machine, but it may be applied to any machine employing the same principles. The drawing also i].- lustrates a single column or twelve em slug, but my invention can be applied to any desired size such as double column and thirty em.

In the annexed specification and appended claims, I desire to cover my invention in whatever form it may be embodied.

Referring to the drawings:

Figure 1 is a perspective view of a portion of the vise and mold with my invention attached thereto, and with the knife block removed for purposes of illustration.

Figure 2 is a rear perspective view of a portion of the vise, illustrating my invention attached thereto.

Figure 3 is a sectional view taken on the line 3 8 of Figure 2.

Referring more particularly to the drawings, the numeral 1 indicates a linotype vise of a well known construction, which is formed with a slide 2 extending to an as sembling rack 3. A trimming blade 1 is formed on said vise, the purpose of which will be described later. The mold ft is driven by the gear 5 in the usual manner. A knife block A is secured to the vise 1 and spaced therefrom in the usual manner. The slug 6 is shown in Figure l in the process of ejec- Serial No. 617,468.

tion from the mold. This slug has large letters cast upon it and it will be seen that the standard machine would trim the let ters, to the width of the slug, between the blade 1 and the knife block as the slug was ejected between them. To allow for this additional width, I cut a channel 7 in the blade 1 of any desired height, that is, single or double column, etc., and of a. suflicient depth that the large letters will just clear the channel. Then it is desired to use the machine for standard work a slide 8 provided with a trimming edge is provided to fill the channel 7. A guide 9 is formed on the slide 8 which is adapted to set at one edge of the slide 2 and prevent the slugs from falling off. A handle 10 is provided on the slide 8 to facilitate its easy removal, A plate 11 is secured to the slide and it is formed with a lug 12 which rests against the vise 1. A holding screw 13 is screwed into the vise l and extends through the lug 12 and has formed upon it two pins 14 which engage said lug to hold the slide securely in place.

Having described my invention, I claim:

1. In combination with a type bar casting machine having a vise, a trimming blade on said vise, a portion of said blade being removed and a knife block adjacent said trimming blade. and means on said blade for permitting the space between said blade and said knife block to be increased by removal.

2. In combination with a type bar casting machine having a vise, a. trimming blade on said vise and a knife block adjacent said trimming blade, said blade having a channel formed therein, and removable means for filling said channel.

In combination with a type bar casting machine having a vise, a trimming blade on said vise and a knife block adjacent said trimming blade, said blade having a channel formed therein, a removable slide forming a part of said blade and adapted to fit into said channel, and means for holding said slide in said channel.

4:- In. combination with a type bar casting machine having a vise, a trimming blade on said vise and a knife block adjacent said trimming blade, said blade having a channel formed therein, a removable slide forming a part of said blade and adapted to fit into said channel, a plate secured to said slide, said plate having a lug formed thereon which.v is adapted 'torest against said vise, and a screw carrying pins extending through a slotin said lug into said vise.

5. In combination with a type bar casting machine having a vise, a trimming blade on said vise, a knife block adjacent saidtrimming blade, said bladehai 'ing a channel formed therein, removable means for filling said channel and a type guide carried CHARLES E WEEKS
