GUIDE FOR LINOTYPEMACHINES.

Specication of Letters Patent. Patented NOV. 16, 192() Application led February 4, 1918. Serial No. 215,290.

-linotype machines for controlling the movement of linotype slugs.

The object of my invention is to provide a device for guiding the slugs or type-bars as they fall down the chute upon the stick or assembly platform, which shall be capable of being quickly and readily adjusted to guide long or short slugs; which shall be simple in construction; whichshall always be in position for use; and which shall be readily eXtensible and retractable as to length.

My invention consists in an inclined stick or assembly platform adapted to receive slugs of different lengths at its upper edge and down which the slugs are adapted to slide, in combination with a wall or guide which is adjustable as tov length so that either short or long slugs may be properly guided as they descend the stick, to the end that whenv long slugs are produced the wall or guide may be retracted so as to not interfere with the proper assembling of the slu s upon the platform. Y f y invention also consists inthe several features of construction and in the arrangements and combinations of parts whereby I am enabled to attain the above mentioned and other objects and all as hereinafter described and particularly pointed out in the ap endedclaims.

y invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which:-

Figure 1 is a fragmentary side elevation, partly in section, of the front part of the slug making mechanism of a linotype machine;

' Fig. 2 is a fragmentary front elevation of the portion of a linotype machine shown in Fig. l;

Fig. 3 is an enlarged fragmentary vertical section on the line 3 3 o f Fig. 2; and

Fig. 4 is a substantially horizontal section on the line 4--4 of Fig. 3.

This present invention is particularly related to and useful in conjunction with my inventlon of a type-bar sawing device as disclosed in my co-pending application Number 825,049, filed March 16 1914, for patent on linotype machines. Ihe device of theformer application was especially adapted for producing linotype slugs or typefbars of different or varying lengths from a fraction of `an inch to five inches or more, and in the use of said device upon llnotype machines of Standard make, I have found a difficulty in properly assembling the different lengths-of slugs upon the stick or assembly platform of the machine. My present invention has for its object the overcomingv of this diiculty.

In the said drawings 1 illustrates generally the forward part of the slug prov ducing mechanism of a linotype machine as provided with my slug sawing mechanism illustrated and described in'my said copending application. l

-Linotype machines are usually provided with a mold wheel 2-provided with mold slots 3 in which slugs 4 of substantially five inches in length are cast. The machine also has a reciprocating slug ejector 5 which is adapted to'force the Slug 4 out of the mold 3 when the same is in a vertical position, as shown in the drawings. As the slug is pushed out of the mol'd 4 by the ejector 5, it passes through a trimming mechanism 6 by which'it is sized as to thickness, and in front of this trimming mechanism I have arranged a slug cutting saw 7 in a casing 8.

The saw is carried by a shaft 9 and is movable up and down in front of the mold slot by the mechanism fully described in my said co-pending application. The saw 8 is thus arranged for the purpose of cutting the slugs as they are ejected from the machine into an upper and a lower part. The upper part is waste and passes out of the machine down a waste chute, not shown, and the lower part carries printing characters and is the article which it is desired to produce upon the machine. This lower or printing part 10 of the slug, as soon as it is severed from the upper part, drops vertically down the narrow vertical chute 11 upon a curved guide plate 12 by which it is turned with its forward or printing face uppermost, and it then slides Vdown upon the downwardly inclined stick or assembly platform 13. As

shown'in the several figures,

upperl ed and, as il the stick is wide enough from itsl lowerV edge 14 to its e 15`tov receive the lon est slugs,

of whatever lengths, ,slide down upon this platform until their/lower ends rest against the rib or ridge 14 atthe lower edge of the stick.' To' close 'one side of the chute 11 and immediatel thus form the narrow vertical chute down which the slugs drop, plate 17 which I extend at its lower end down over the upper part of the st ick 13. At the lower part ofthe stick and 1n sub'- .stantial alinement with the plate 17 is a described as to its operation, except to say forms Vone wall ofthe slot down w that as a slug slides down` it draws back into alinement with the plate 17 and out of the path of 'the descending slug, and then 1mmediately moves forward and pushes the slug along the stick out of the path of the next descending slu As best shown ingig. 2, the forward face late 17, ich the slu l fall,'and my invention relates articular y to an extensible and retractab e'gulde which is adapted to form the opposite wall of the said chute or slot.

For this purpose I provide a jointed guide 20 formed of a series of short thin strips or bars 21 pivotally joined end to end and capable of being folded back upon themselves, as shown Iin full line in Fig. 2, or extended in end to end relation, as shown in dotted lines in said figure. I pivotally mount this jointguide at one end to the linotype machine at one side of the chute 11 near the lower end thereof or where the slugs strike the curved plate or guide 12. The guide 20 is set on edge and is capable of being extended or lengthened in position opposite to the lower end of said plate 17 and the inner face 19 of the pusher 18 so as to form the opposite wall of the chute down which the slugs move on the stick 14. I make the guide 2() yieldable laterally so that even should a slug be caught between the end of the pusher and the guide no dama e can result.

It will now be c ear that I am enabled to guidethe extremely short slugs as well as the longer ones, chine from producing short slugs to produc- 19 of the pusher, together with the ustrated'in Fig.- 2, allo the slugs,

I provide the thin stick. This and when Ichange the mainglonger ones, I can readily shorten the guide 20 to vpermit longer slugs to be properl7 assembled by the pusher 18-' will also be plain that I can quickly and readily lengthen or shorten the guide' 20' to properly guide any length of slug which can be produced upon the machine,

and that when producing full length slugs the guide can readily be folded back out of 'ducing type bars of various lengthsv and having an inclined stick or slug assembly platform, the combination therewith of a rlaterally yieldable slug guide extending over saidplatform, said guide being retractable and extensible for accurately guiding type bars'of various lengths as they slide down said inclined assembly platform. 2. In a'linotype machine capable of producmg type bars of various lengths and having an inclined stick or slug assembly platform down which the slugs are adapted to slide to be assembled in column form, a slug assembly member adapted to push the slugs laterall into column form, and a foldable gui e arranged over said stick adapted to be pulled out or pushed back to adjust its length to correspond with the length of the slugs being produced, and said guide being yieldable inthe direction of the transverse movement of thev slugs as they are assembled into column form to prevent inadvertent stoppage of the slug assembler.

3. In a machine of the kind described, having an inclined assembly platform down which the type bars slide'to be assembled in column form, a guide projecting over the platform composed of a plurality of yieldable members pivotally joined at their ends and adapted to be extended over the platform in end to end relation to guide short length type bars down the platform and adapted to be folded back in parallel relation to properly guide longer type bars down the assembly platform and to permit the longer type bars to be moved transversely by the assembler member.

In testimony whereof, I have hereunto set my hand this 2 day of February, A. D. 1918.

CHARLES L. MOHR.
