LUTHER SHERRHJL, OF NASHVILLE, TENNESSEE, ASSIGNOR TO MERGENTHALER LINOTYPE COMPANY, A CORPORATION 0F NEW' YORK.

TYPOGRAPHICAL MACHINE.

To all lwhom t may concern.'

Be it known that I, LUTHER SHERRILL, a citizen of the United States,l residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Typographical Machines of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to typographical machines, such as linotype machines of the eneral organization represented in Letters atent of the United States to O. Mergenthaler, No.- 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appearl in print and then composed in line in an assemblin elevator, the composed line then trans erred through an intermediate channel into a vertically movable first elevator whichlpresents 1t to a mold, whereupon the mold is filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through a distributing mechanism to the magazine from which they started. More particularly, it relates to that class of machines designed to handle matrices provided with two or more superposed characters, and wherein the assembling elevator, intermediate channel, and first elevator are each provided with two sets of supporting rails whereb the matrices may be composed and maintamed at an upper or lower level, or both, as desired, to locate the selected characters in operative position.

W'hen it is desired to cast a'slug from the lower characters of all of the matrices of a composed line (as for a solid line of italics), it is the usual practice to assemble and maintain such matrices, not at the upper level as would otherwise be required, but at the lower level, and then to arrest the rst elevator in a slightly raised position so as to locate the selected characters opposite the mold slot, such arrest of the elevator being ordinarily effected by a stop member mounted on the vise frame and adapted to be thrown into action at the willof the operator. Similarly, in the use of head-letter matrices or matrices with characters above 14: pt. the same practice is followed so as to eifect the proper alinement of the matrix characters with the mold. slot.. The foregoing practice Specification of Letters Patent.

Application led .Tune 28, 1920. Serial No. 392,207.

has given rise to very serious objections, as 1t frequently happens that an operator, through oversight or carelessness, will assemblematrices at the upper level while the elevator stop is in action, which will result.

vent the delivery of the matrix line to the mold except under the proper conditions. To this end, the machine is equipped with a safety device which acts when the elevator stop is in active position to prevent the transfer of the matrix line into the elevator, unless such line.is composed at the. lower level. In the embodiment herein illustrated, the stop is in the form of a pivoted lever carried by the first elevator and movable to active or inactive position thereon,.and the safety device is in the-form of a rod connected at one end to the pivoted lever and having its other end arranged to be moved into and out of the first elevator at its entrance, the arrangement being such that when the stop is moved to active and inactive position,

the rod will be 'projected into and withdrawn` from the first elevator respectivel thereby preventing or permittingthe transfer into vsaid elevator of matrices standing at the up- .per level, according to the position/of the lplied to the speciic kind of machine mentioned, but obviously manyl changes and variations may be made therein without departing from the spirit of the inventio which, it is therefore to be understood is no limited to any .specific form or embodiment except in so far as such limitations are specified in the claims.

Referringto .the drawing Figure 1 is a front elevation-of a portion of a linotype machine having the present improv'einents applied thereto:

Fig.. 2 is a vertical section taken through the casting mechanism, and showing the first elevator in raised position preparatory. to the engagement of the mold with the matrix line for the casting operation; and I Fig. 3 is a top plan view of the parts shown in Fig. 2.

The matrices X (herein. shown as of the two-letter variety) ai'e stored in the magazine A and are released' therefrom in the v usual way by the manipulation of the keyboard B, whence they pass into the assembling elevator C wherein they are composed in line. After composition of the line, the elevator C is raised into registration with the intermediate channel l), such movement of the elevator tripping the transfer carriage E, which thereupon shifts the composed line to the leftinto the first elevator or transporter F. 'llhe first elevator then descends to locate the line before the casting mold G, which immediately advances from therear into engagement therewith preparatory to the casting operation, all as well understood in the art. As before indicated, the assembling elevator C, the intermediate channel D, and the first elevator F are each provided vvith two sets of supporting rails, for sustaining the matrices at the upper or lower level, as required. rllhis construction is so well known that no detailed description thereof seems necessary, but, to identify the parts, it may be noted that the matrices are sustained at the upper level in the assembling elevatorl C by the retractable rails C1 and C2 (Fig. l) and in the first elevator F by the retractable blade or rail F1 (Fig. 2), which latter figure also shows the fixed rails F2 for sustaining the matrices at the lower level in the first elevator. lt may also be noted that the mold Gr is formed at the frontI with the two superposed grooves G1 and G2, in one or theother of which the alining ears of matrices engage according to the `level at which they are sustained in the first elevator. ing lof the construction and operation of these parts is desired, reference may behad to the Rogers Re. Patent No. 13,489.

ln the normal operation of the machine, the first elevator F is allowed to descend to its lowermost position, as determined by the engagement of its set-screw F3 with the top face of the vise frame H. ln this connection, it is pointed out that the elevator is provided with a second set screw F4 arranged to engage and depress the vise automatic l 1 as the elevator comes to rest. However, for reasons previously noted, the machine is usually equipped with a stop member which may be thrown into action at will to arrest the first elevator in a raised j position with reference to the mold, as shown in Fig. 2, but when the elevator is thus arrested, it is necessary that the matrices be sustainedtherein at the lower level, as.

otherwise the objections before mentioned will arise. Thns, if the matrices were sustained at the upper level, as indicated by the dotted lines in Fig. 2, it is evident that their lower ears would fail to enter the upper alining groove G1 of the mold G as lf a fuller understandieeenee the latter advances from the rear, so that injury to the parts or a bad squirt would necessarily result.

According to the present invention, and to obviate the foregoing objection, means are provided to prevent the entrance of the composed line into the first elevator at the upper level when the elevator is to be arrested in its raised position. To accomplish this result, specically, the stop member 'for the first elevator is mounted directly thereon, and the elevator is further equipped with -a device connected to the elevator stop and which is arranged to be projected into and out of the elevator as the stop member is moved to active and inactive position,.re spectively. ln the preferred embodiment illustrated, the elevator stop is in the form of a horizontally disposed angular lever 0 pivoted to the underside of the elevator head by a screw-bolt or pin 01 and provided on. its two varms with interponents 02 and 03, respectively, the former being arranged to coperate with the set-screw F3 which limits the descent of the elevator, and the latter being arranged to coperate with the set-screw F 4 which actuates the vise automatic H1. The longer arm of the pivoted lever projects to the right beyond the elevator head (Fig. 3) so as to provide a handle portion within easy reach of the operator while seated at the keyboard, and stop pins O4 and O5 serve to limit the movement of the lever in opposite directions. rlihe pin O4 is arranged to arrest the lever in its active position i. e. with the interponents 02 and 03 beneath their respective set-screws F3 and F t as shown by the full lines in Fig. 3, while the pin 05y is arranged to arrest the lever in its inactiveposition 1'. c. with the interponents located clear of the set screws as shown by the dotted lines in said figure. lt is apparent, that by adjusting the stop lever to active or inactive position, the first elevator will be arrested in raised relation to the mold (Fig- 2),` or allowed to accupy its normal relation thereto, according to the adjustment of the stop lever.

Referring now to the safety device, it is merely in the form of a small rod F connected at one end' to the handle portion of the stop lever 0 and having its opposite end slidably arranged in a hole or opening cut through the front wall of thel first elevater at its entrance and ata point located above the fixed matrix supporting rails F2, the length of the rod being such that it will be projected into and withdrawn 4from the elevator as the stop lever is moved to active and inactive position respectively. Consequently, if the matrix line should be improperly composed at the upper level while the elevator stop isin action, the rod F will bar the entrance to the first elevatorchannel (Figs. 2 and 3) and thus prevent the lbe assembled at their lower level before the'y can be transferred into the first elevator for the type casting operation. It will be understood, of course, that when the elevator stop lis out of action,l the matrices may be composed at the upper or lower level or both, as the elevator in such condition ofthe stop is permitted to descend to its normal position.

It is 'particularly noted that, in the foregoing arrangement, the parts are extremely simple and can be made at small cost and aplied to the machine without the slightest di culty `or delay', and this without involving any radical alteration in the existing machine parts. In addition, the arrangement is strong, durable and compact and such that it may be easily and conveniently manipulated. The form and arrangement of the elevator stop as above described is also very advantageous, quite apart from its association with the safety device,.it being remembered that the stop lever is carried by the first elevator and is provided with a handle portion projecting beyond the same toward the right within easy reach of the operator while seated at the. keyboard.

These and other advantages will be apparent to those skilled in the art. However, in its broader aspects, the invention is not limited to the precise construction shown and described, as many changes may be made in the details thereof and still be comprised within its scope. Generally speaking, it is to be understood that the invention is not limited to any specific form or embodiment except in so far as such limitations are specified in the claims.

Having thus described my invention, its construction and Inode of operation, what I claim is as follows:
