COMPANY, OF NEW YORK, N. Y., A CORPORATION OF vrsn-av ronerrc.

Patented May It, 1915.

Application filed May 23, 1913. Serial No. 769,537.

To all whom it may concern Be it known that I, THoMAs S. HoMANs, a

v citizen of the United States, residing at Hempstead, in the county of Nassau and State of New York, have invented new and useful Improvements in Vise-Automatics,

or which the-following is a specification.

This-invention relates to improvements in line composing and line casting machines, and more especially to those of the linotype class wherein each line of matrices is pre--- sented to the mold by an elevator and the mold is moved up to the line of matrices preparatory to each cast.

The primary object of theinvention is to provide improved means for automatically interrupting the operation of the machine should. a line of matrices be improperly presented to the mold, thereby avoiding damage to the matrices or to any part of the machine.

.To this end, the invention consists in certain improvements, and combinations and arrangements or parts, all as will be hereinafter more fully described, the novel fea tures being pointed out particularly in the claims at the end of the specification.

In the accompanying drawings :-F igure 1 is an elevation of a portion of a machine of the linotype class as viewed from the left-hand side and embodying the present invention; Fig. 2 is a front elevation of the parts shown in Fig. 1; Fig. 3 is a detail perspective view of a portion of the stop or safety device; Fig. 4 is a top plan view. showing the vise frame and elevator in horizontal section, and having the present invention applied thereto and shown in position to permit operation of the machme; Fig. 5 1s a view similar to Fig: 4 but showing the device in a position to interrupt and prevent operation of the machine.

Similar parts are designated by the same reference characters in the several views.

. In the accompanying drawings one example of the invention is shown in connec-- tron With-a machine oi the well known linotype class as described and illustrated fully in the patent to O. lvlergenthaler, No. 436,532 granted September 16, 1890.

In the present instance 1 designates the disk or gear wheel which carries one or more molds 2.

3 designates the elevatorslide forming part of what is generally known as the first elevator, this elevator slide having an overhanging head at the top which carries jaws 4 which receive each line of matrices M between them, and'when the elevator is lowered the line'of matrices held by the elevator jaws is lowered to the proper level to be engaged by the mold 2. The elevator is guided to operate vertically on the vise frame 5, the latter having a cap 6 at the top which also guides the, elevator as well as the vise jaws which clamp the line of matrices in an endwise direction, all as will be well understood by those skilled in the art. The mold disk or wheel 1 is revolubly supported by a bearing7, this hearing being carried by a horizontally movable slide 8, and the slide 8ois provided with means for reciprocating it and consequently the mold disk or wheel 1 horizontally to move the mold 2 into engagement with the line of matrices supported by the elevator, preparatory to the casting of a slug, and after the cast has been made, the slide, together with the mold disk or wheel, is retracted or moved rearwa'rdly away from the mold, whereupon'the elevatormay ascend to carry the line of matrices to the distributing mechanism and the mold disk or wheel maybe rotated in the usual way to bring the mold containing the cast slug to the ejecting position. I

A vertical screw 9 is fitted in the vise,

. frame 5 and constitutes an adjustable stop;

the upper end of which is arranged. to be engaged by the under. side of a slide 10, the latter being fitted in a horizontal guideway 1] formed in the elevator slide 3. This slide 10 has a handle 12 whereby it may be shifted laterally at will, a guidepin 13 being provided to retain the slide in position and the under sideof the slide is formed with a 'I'BCQSS orinotch 14, shifting of the slide into the right-hand position as shown in the drawings bringing the unnotohed portion of the slide into position to engage the top of the screw 9 and shifting of the slide toward the left bringing the notch or recess 14 of the slide into a position to receive the upper for a purpose that will hereinafter appear. 0-

The mold slide 8 carries a guide 18, the latter having flanges to cooperate with the front and rear faces of the mold disk or' wheel, and a rigid arm 19 is fixed to saidguide and projects into a position to push forwardly the left-hand end of a bar 20 when the mold disk or wheel is shifted forwardly into the casting position. The bar 20 rests between lugs 21 on the vise frame 5, the upper lug 21 at the left-hand side being notched to receive a guide-pin 226m the bar 20, and the upper lug 21 at the right-hand side-of the vise frame having a retaining projection 23 to cooperate with a pin 24: on the bar.

, retain the left-hand end of the bar 20 in engagement with the arm 19. The opposite or right-hand end of the bar 20 extends into a position where it will engage the roller 26 carried by a lever 27 This lever 27 is adapted to cooperate with the startin lever 28, the latter being pivoted at 29 an provided with an arm 30 which is pivotally' connected to a link 31, the links 30 and 31 constituting a toggle and the link 31 being connected to the bar 32 which, when the toggle links are straightened, throws the main clutch of the machine out of operation and thereby stops the machine. The starting handle and toggle operate substantially as disclosed in the Mergenthaler patent above referred to, and in the machines at present in use, to disengage the main driving clutch and interrupt the operation of the machine when the toggleis straightened as-shown-in Fig. 5, the clutch being engagedand'the'machine in running condition when the starting handle is in-the position shown in Fig. 4. The lever 27 when pushed into the position shown in Fig. 5 by the -bar 20 will shift the starting handle into stopping position and will engage behind a lug 33 of the link 30 and thereby stop the machine and prevent further operation thereof. A lug 34 projects forwardly from the forward side of the bar 20, this lug serving as a fulcrum when it abuts against the slide 10 whereby the forward motion of the, mold slide will cause the arm 19 to push for- .wardly against the left-hand end of the bar 20 and thereby cause the bar 20 to rock about the lug 34: as a fulcrum, moving the right-hand end of the bar 20 rearwardly and into stopping position, asshown in In the construction shown in the present instanq/r, the machine is capable of handling :hand position, the lower unnotched face of A tension spring 25 operates to the slide then coming against the stop screw- -9, and in using the upper characters on the imatrices', the slide 10 is shifted toward the left and the notched portion 14 in the slide surface 16 on the slide 10 when this bar 20 .on the bar '20 will just clear-the stepped is pushed forward by the correspondingmovement of the arm 19 which occurs when the mold is moved up to the line of matrices prior to the cast.

When the slide 10 is moved toward the left, (as when the upper characters on the matrices are being used) the lug 34 on the bar 20 will-then just clear the top surface 17 on the slide 10 when the,

mold is moved up to the line of matrices,;

and in these two cases, when the matrices are properly presented to the mold, the bar 20, will not rock so as to move the starting handle into stopping position for the rea-,'

son that the lug 3 1 does not bear on a fulcrum. If, however, the elevator. does-not' descend to the proper point so as to bring,

theline of matrices correctly between the jaws of the vise, then the lug 34 will bear against the-rear side of the slide lO or the downward extension 15 vthereon, and the bar 20 will then rock in the manner shown in Fig. 5, throwing the clutch into disengaged condition and interrupting the operation of the machine. After the cast has been made, the mold slide recedes from the line of matrices and the elevator rises to carry the line of matrices to the distributing mechanism.

In machines of this class, the mold slide is moved forward during the time the ele- -vator is raised, for the purpose of ejecting the slug from the mold. The automatic stop which insures correct presentation of the matrices to the mold, as constructed in accordance with the present invention, will not interfere with this advancing movement of the mold wheel during the slug-ejecting operation, as the slide '10 and its extension 15 are then clear of the bar 20 and its fulcrum lug 34, and the operation of the machine therefore will not be interrupted. The present invention avoids the necessity of using special devices to prevent stopping of the machine during this ejecting period, the stopping device of the present invention being controlled )ositively according to the position occupied by the elevator and independently of the position of any intermediate parts. Also, the stop device of the present invention is inoperative when theelevator is raised toits upper position, as

well as when the elevator is lowered to its proper limit, and it provides a very simple ent positively on the position ofthe elevator as the elevator in that construction 'mnst push down'a vertically movable rod which is held up by a spring, and it frequently occurs that the rod remains down after operation of the machine due to binding or friction in the hearings, or for other reasons, and hencethe subsequent operations of the machine are not controlled by the safetyv device.

7 I claim as my 1nvent1on:

1. In a machine of the linotype class, thecombination with the first elevator for lowering a line of matrices to the casting level, the casting mold, the slide for carrying the mold against the line of matrices, and stopping means for the machine, such means being actuated during the forward movement of the mold and governed solely according to the position occupied by said elevator whereby operation of the machine will be interrupted should the elevator fail to present the matrices properlyto the mold.

2-. In a machine of the linotype class, the combination with themold, the slide carrying it, and the first elevator, of stopping means for the machine embodying a member-acted on by the forward movement of the mold-carrying slide, and a part in the first elevator adapted to form an operative conne'ctionfor said member, said part being inoperative relatively to said member when the lirst elevator is lowered to a position to' properly present matrices to the mold.

3. In a machine of the linotype class, the con'ibination with the mold, the mold-carrying slide, and the first elevator, of stopping means for the machine embodyi' g a lever arranged to be acted on by said mold slide during its forward movement, and a part on the elevator adapted to cooperate with said lever as a fulcrum, the stopping means being inoperative when said part on the elevator 15 above or below said lever.

4. In a machine of the linotype class, the combination with the mold, the mold-carrying slide, and the first elevator for presenting a line of matrices to the mold, of stopping means for the machine embodying a member arranged to be actuated by the mold slide as the latter brings the mold against the line of matrices, and a part on the elevator arranged to form an operative connection for said member when the elevator fails to bring the matrices to the proper casting level, said part on the elevator being adjustable to provide for the use of the upper or lower characters of pll[rail-character matrices.

In a machine of the linotype class, in combination with, matrices having a plurality of characters, the first elevator \for bringing a line of matrices down to casting position, and a. stop block having two sets of steps, each corresponding to the different character levels on the matrices, one "set, being adapted to stop the downward travel? of the elevator at the different levels as de sired, and the other set adapted to control the stopping, of the machine in event ofthe elevator not r arching the stop of its down ward travel.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
