T all whom it may concern:

- Be'it known that I, Fnrrz C. Lucnr. bAir,

of New York city, in the county and State of New York, have inventedeertain new .and useful Improvements in Line-Casting Machines, of which the following is n specificat-ion. i I

These improvements in line casting ma: chines have to do with the mold in which the slug or'line is case-said mold being a travelinginold, which moves from casting to ejecting position and return, as usual in machines orihis class; and they relate more particularly to a traveling mold ofv this character which is varis'bleas to the length and width of its mold space and is combined with suitable means for automatically closing the mold to one 'len th and width or another as required, and a so with means for automatically opening themold in both directions during its travel. A mold of this general character is not here broadly claimed, inasmuch as I have made it the subject of my patent for improvements in line casting machines, No. 944,981 of December 28, 1909. In the mold of my said patent the closin of the mold to predetermined lengthand width, takes place through the agency of spring actuated means which automatically o crate as soon as the mold, on its return movement from ejecting to casting position, quitsthe devices by which it is opened in both directions. In my present application, in lieu of said spring actuatedv means, I employ stops which operate not only automatically but positively to close the urold to. redetermined length and widththis action taking place near" the close of the return movement'of the mold from ejecting to casting position; and these stops I unite with independent ad usting means whereby the sto 5 may be set to close the mold antomatical y and positively to varying lengths and widths as required. 'In this way the action of-the parts of the mold is rendered more certain and accurate, and I am cnabifed to dispense entirely with spring actuated .mold closing devicesn point of some practical importance, inasmuch as the heat due to the casting operation is apt to have an injurious influence on the springs used for this purpose.

In the accompanying drawing to which. I shall now refer for a better understanding of my. improvemcnts-Figure l is a front elevation of a mold embodying my improve- Linn-cesium G- mecnmn.

In the drewings'G is the carrier frame.

F is the slide mounted in the carrier frame and adapted to slide'thercin for the zurpose of convcyingzrhe mold from. cast- .llfi to ejecting position and return. r I ihe mold consists of the cotton and top jaws l, 2, mounted in the slide, and the 7 sprin -impelled spring yielding side pieces 3 an ,5 housed in and interposed between the jaws. These pieces. which form. the, eside walls of the mold, sre housed, the one, I 3, 1n the lower aw, and the other, 5, n the upper jaw. They are spring pressed by springs 4 and 6. each to ard lhe'fucc of the. opposite jaw, and they-form tight filing side wallswhich are self sting to verity tions in riLiiniir-t; l'etween he top and botion: jaws.

This movement of the-lower .jniv will, according to its direction, cause the' side-piece 3 which it carries to approach'or rccede from its fellow side piece carried.

The slide l is held and guided in its movetudinul rib 30 on its'top, which enters u corresponding grlimve in the carrier frame; and, by a. rib 22 on itsbottczn, which enters .1 corresponding 3, grt' ove in the bottom to the carrier frame. ll-ih is formed as a rack to engage a pinion 21 mounted in by which the slide may be moved at proper intervals from custingto ejecting position and return.

The parts thus far described are the some my aforesaid Patent No. 944,981.

In order to open and close the mold, I provide the wedge 15, with an upwardly 23, 23 againstwhich alternately the linger between casting sndejecting position. V The linger 15 corresponds to the like designated part in my aforesaid Patent No. 9-l .95l. It extends up from the Wedge through a slot in the slide F and projects into 3. longitudinal channel formed in the top of the rib 30.

The stop 23, corresnoncls in purposeand function to the. like designated part in my suidPatent No. 99 931. As the moldmoves to the right from the position shownin Fig. l to ejecting position, the stop 23 meets the finger 15', and thus arrests the wedge 15, slightly before the mold reaches eg'eciing. osition, in this way relieving'the upper In order to again close the mold the stop 23' is so located t-lirit' on the return of the. mold from ejecting to rusting position itmeets the finger 15- and thus arrest-s the wedge 15 slightly before the mold reaches casting position; andus the wedge isthus held stationarywhile the mold still continues wedge positively forces down and closes the pressed is determined by the position of the stopv 23' relzitivel to the finger .15", and therefore by making this stop 23'- adjustable so that it will meet the finger 15" sooner or later during the return movement of the as desired. Obviously such edjustment can be provided for in many Ways. I prefer for this purpose toforin both sto s 23, 23 on, or firthem to, a bar a, at a from each other slightly less than the length of traverse of the slide, the her being adjustistance apart ably secured to the top of the carrier frame G by thiunb screw or bolt 3' which passes into the topof the frame through longitudimi slot 3 in the bar. The stops project down through slots in the carrier frame into the path'of moieuient of the finger 15". By aefiusting the our lengthwise of the-frame Gr the position of the closing stop 23 can be varied at will to determine the width of the mold. space. At the same'tinie, inasmuch as the distance between the two stops 23, 23 is invariable, it follows that no matter what may be the width o1 the slot, the 0 ening movement of the mold will always e the some.

To open and close the mold lengthwise, and to vary the length of the slot, I use a similar system of stops in connection with the lower jaw, with the difference, however, that in this case the two stops are not connectcd so as to be adjustable together, but

the closing stop is adjustable-dude endently ofthe opening stop, \vlnch :ndee' may he,

' and preferably is, a fixed stationary stop, by .the'acnon or which the mold space is opened always to its maximum length, whatever may be the position of the closing stop. Munifestly the structural details of devices for this purpose inoywvidel vary Under the arrangement shown in t. e drawing, the stationary opening stop is formed by the vertical our 6 which is seen ed to the top and bottom rails of the carrier frame G and extends in front, and crosswise The closing stop consists of a horizontal rod t, parallel with the face of the mold and mounted in :1 vertical bar f which, like the vertical bar t, is secured to the top and bottom rails of the carrier frame G. The end of o f the mold.

closing stop rod 25, and the verticul opening I bar t, are in the path of movement of :1 finger'or other projection 'r on the lower aw 1.

In order to adjust the sto') bar 15 so that it shall meet. the finger a sooner or" later during thercturn movement of theimold from ejecting to casting position, the stop her fits in a horizontal undercut guide groove on the innot face of the arm t wherein it can move lengthwise; and it is held in adjusted position by a set or clamp screw 15, as shown more clearly in Fig. 7. Thus by varying the position of 'ie closing sto t-', the length of the mold slot or space can e varied at pleasure. But whatever the length of, the mold slot when closed, itwill always be opened by the stationary stop 6 to the same extent-tlmt is, to the maximum length.

i may connect the two stops t, t for the lengthwise opening and closin just as the two stops-23, So, For the widthwise opening and closing are connected; or I may make the two stops :23, 23 separate, and with separate provisions-tor adjustment. 4 i

It is not important that the widthwise opening stop 23 be adjustable, any more than in tht case of the lengthwise opening stop t. But it is essential. that the closing stop 23' should be both longitudinally adjustable and combined with means for hold ing it rigidly-and unyieldingly in its adjusted position. The capacity for lengthwise adjustmentis essential because thereby the width of the slot is determined; and. the stop in whatever position it may be set must be rigid and unyielding, because it cannot otl erwisefinsin'e the accuracy of closing which is indispensable to good work. The

arrangement, however, which on the whole- I prefer isillustrated in the drawing. Ob-

viously these and other structural details of the mold can be. widely varied by the skilled mechanic without departure from the spirit of myinventiom' I therefore do not'limit myself to the particular details of construction herein shown and described in illustration of my inventionz'But What I claim and desire toseeure by Letters Patent is as follows: a

1. A linotype mold mounted to recipro cate bodily and comprising, in combination,

ing the upper jaw, stops 23 23' for automatically and positively moving he. wed 'e in relation to the other parts as the mo d moves to and fro, and means for adjusting said stops.

3. The reciprocating linotypemold ineluding the wedge to vary the width of the mold space in combination with a front stop to move the wedge in a direction to ermit the mold to open, a rear stop longitut inally adjustableto move the wedge in a direction and to an extent to close the mold to any predetermined widthaand means for holding the rear stop rigidlyv in adjusted position.

.4. A longitudinally reciprocating linotype mold having one member movable longitudinally in relation to the others for the purpose of changing the length of the mold space in combination withstops for automatically and positively opening and closmg the mold to one length or another durin its movement to and fro.

5. A longitudinally reciprocatin linotype f mold having one member movable longitudinally in relation to the others for the pur pose of changing the length of the mold space, in com ination' with a fixed, stop for automatically opening the mold to maximum length, and an adjustable stop for automatically closin the mold to one length or another as desire 6. Ina line casting machine, a traveling mold variable as to the length and width of the mold space in combination with adjust able means for automatically and positively closing the mold to one length and width or another as required, and means for automatically opening the mold in both direc-' tions during its travel. 7
