TYPOGRAPHICAL CASTING-MUERTE.

Specification of Letters Patent.

Application led July 28, 1916. Serial No. 111,765.

To all whom 'it may concern:

Be it known that I, GEORGE P. KINGSBURY, a citizen of .the United States, residin -at Brooklyn, in the county of Kings and tate of New York, have invented certain new and useful Improvements in Typographical Casting-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler, No. 436532, wherein a type bar or slug is cast in a slotted mold against an assembled line of matrices presented momentarily thereto and confined between a pair of clamping jaws, and wherein the slug after casting is removed from the mold by an ejector which advances from the rear' and pushes it forwardly between a pair of trimming knives into a receiving galley at the front of the machine.

In practice, it is frequently necessary to produce the type bars or slugs of different lengths to accord with the width or measure of the body or columnv to be printed, and this practice necessarily involves the use of molds of appropriate length. It is also essential in most instances that both the ejector and the line clamping jaws be adjusted to correspond to the length of the mold in use or the slug to be cast therefrom. It sometimes happens, however, through carelessness or inexperience, that the operator failsr to make these adjustments, which failure often leads to disastrous results. For instance, if the ejector blade is too lwide to enter the mold, serious damage is bound to occur, and the same is true if the distance between the clamping jaws is less than the length of thecomposed line; or if the distance between the jaws is greater than the length of the line, a bad squirt is apt to result. l l

is the object of my invention to obviate the' foregoing objections, and to that end,

I have provided mechanism which insures the'corresponding adjustments of the line clamping 4and slug ejecting devices. More specifically, I have connected both of these mechanisms to a common adjusting means, so that the adjustment of one effects the corresponding adjustment 0f the other. .In

be made therein which will still be comprised within its spirit. I therefore desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specied in the claims.

Referring to the drawings:

Figure l 'is a front perspective view of detached portions of a linotype machine with my -invention applied thereto;

Fig. 2 is a vertical section through a portion of the jaw adjusting devices;

Fig. 3 is aside elevation, partly in section, showing theconnections between the line clamping and slug ejecting mechanisms;

Fig. 4 is a section on the line 4 4 of Fig. 3;

Fig. 5 is a similar view showing the parts in different relative positions, and

Fig. 6 is a section on the line 6 6 of Fig. 5.

There are two general methods followed for casting type bars or slugs of different lengths, one involving the employment of a so-called adjustable mold, i. e., one whose mold slot may be shortened or lengthened to the required extent, and the other involving the 'use of a plurality' of interchangeable molds having casting slots of the dierent lengths desired. In the present instance,

this latter method has been adopted for purposes of illustration. The several molds, only one of which is shown, marked B, are carried by the disk'B-1 (see Fig. 3) which is rotatably mounted upon the mold slide B2 so as to present the selected mold first in a horizontal position to-coperate with an assembled line of matrices, and thereafter to carry the mold around to a vertical posiltion, as indicated, to .locate itin front of the ejector mechanism which expels the slug therefrom. Y

During the casting operation, the composed line of matrices is supported before the mold between the clamping jaws C and D suitably sustained in the vise frame A. The left hand jaw D is mounted as usual to slide horizontally in a guideway in the vise frame so that the distance between it and the opposing jaw C may be varied according to the length of line employed. The position of the jaw D is determined by the adjustable straight-toothed rod E slidably supported in the vise frame and passing through a nut or block (shown by dotted lines in Fig. 1) which is adapted to be shifted laterally to a slight extent under the influence of the justifying devices in the ordinary way. The rod E is connected to the nut by the locking bolt or latch G mounted thereon and formed with teeth to engage those of the rod. In effecting the adjustment of the jaw D, the locking bolt G is first raised to disengage it from the rod E, and the latter is then moved endwise in one direction or the other as required. For this purpose, the rod is provided at its outer end with the arm E2 to which is connected the bar or member E3 extending toward the right across the top of the vise frame A and connected to the operating devices later to be described. Before and after the rod is thus moved, the locking bolt G is moved to its inactive and active positions, respectively, these operations being carried out by means of the pivoted springactuated lever H and the underlyin bar I. The bar I is seated upon and carrie by the bar E3, the latter bein provided with a series of buttons or protu erances (not shown) which normally engage in recesses or depressions formed in the under face of the bar I, so that when the bar I is moved longitudinally with respect to the bar E3, it will also be shifted or .cammed laterally to rock the lever H upwardly and disengage the connected bolt G from the rod E. The spring I8 connected at one end to the bar E3 and at its opposite end to the bar I serves to restore the latter to its original position on the former and thus to allow the bolt G to be rengaged with the rod E. The foregoing parts and their mode of operation are fully set forth in the Kennedy U. S. Letters Patent No. 1,139,980, dated May 18, 1915, to which reference may be had for further particulars, if desired.

The slug ejecting mechanism herein illustrated is of the kind represented in the U. S. Letters Patent to John R. Rogers, No. 967,796, dated August 23, 1910, comprising the series of parallel Ablades or sections F1 arranged one above another and guided between the vertical face of the mold slide B2 on one side and the fixedvertical plate F3 on the opposite side. The several sections are free to move forward and backward i11d9' pendently, and also so that any desired number may be brought into action conjointly to form an ejector of a width corresponding to the length of the slug to be cast, while the other sections remain inactive in their backward position. These ejector sections are actuated by the corresponding members F2, mounted in grooves of the mold slide B2 and adapted to be coupled to the main actuating slide F through the medium of the vertically adjustable bar F4, which has its lower end arranged to travel forward and backward on the rod F5 attached to the vertical slide F6. The slide F6 is adapted to be raised and lowered to select vany desired number of the ejector blades for use, or to eHect their operative connection with the main actuating slide F. v

The foregoing parts taken from the two patents mentioned have been selected merely vby way of example and to illustrate a preferred embodiment of my invention, such parts being in practical and commercial use today. It should be understood` however, that my invention may be adapted to other constructions which'might require a totally different form of mechanism from that herein illustrated. My invention is directed broadly to any suitable means which will insure the corresponding adjustments of the line clamping and slug ej ecting mechanisms. In the present instance, such means comprise a common adjusting device connccted to both mechanisms, so that their adjustments may be carried out simultaneouslyv and to corresponding extents.

In the particular embodiment illustrated, the common adjusting device is in the form of an operating hand-lever M2 pivotally mounted at its rear end upon a transverse stud M3 fixed 'in the framework. Also pivotally mounted upon the stud M3 is a further lever O connected at its rear end to the vertical slide F6 controlling the adjustment of the ejector mechanism. These two levers are normally connected together in advance of their pivot by means of a locking pin P, which may however, be operated to disconnect them when desired, as will later be described. The connections between the operating lever M2 and the jaw adjusting means comprise a pair of vertical rods or links L1 and M1, the latter being pivoted at its lower end directly ALo the operating lever, and the former to a hand plate L2 also pivoted thereon, as at L3, and formed with' 'and provided at its forward end with 'a similar bevel gear J meshing with rack teeth I2 formedon the bar I, which controls the jaw locking means.

In eiiecting the adjustments of the parts, the operator grasps the lever M2, pressing in the hand plate L2 to disengage its etooth t L4 from the sector L5. This relativemove-4 ment of the hand plate shifts the connected l rack L upwardly, effecting the independent rotation of the sleeve J2, which consequently moves the bar I longitudinally to theright to disengage the locking bolt G from the j aw adjusting rod E. The operating lever M2 is then moved upwardly or downwardly as re` quired, carrying with it both of the racks L and M, and causing the rotation of their respective bevel gears J and K, which thus shift the rods I and E3 conjointly to the left or right according to the direction of movement of the operating lever to set the jaw D in the desired position. This movement of the hand lever M2 is also communicated to the operating lever O for the ejector adjusting lslide F3, which is accordingly moved upwardly or downwardly as the case may be to select the requisite number of the individual ejector blades F1 or to control their connection with the actuating slide F. After the parts have been adjusted in the above manner, the operator releases his hold upon the operating lever, and the connected plane L2 isI then pushed away by its spring L3 to restore the engagement of its locking tooth L1 with the sector L5 and thus to hold the parts in their operated position. The locking movement of the plate L2 also restores, through the connections described, the rengagement of the locking bolt G with the toothed rod E, which holds the jaw D in its adjusted position. In short, when the distance between the clamping jaws C and D is varied, the width of the ejector blade is altered to correspond, these adjustments being effected simultaneously and by means of a common operating device.

It is sometimes desirable to cast short` lines on long bodies, or the like, in which event itis necessary to set the clamping jaws at a distance apart less than the length of the mold slot, and it may be desired todo this without disturbing the width of the ejector blade. For this reason, I have provided means whereby the operating lever M2 may be disconnected from the ejector adjusting slide F3 at will, so that the lever may be operated to effect the independent adjustment of thei line clamping jaws. the present-instance, such means comprise 'the a. locking pin `P before referred to, which passes transversely through holes or apertures in the levers M2 and O. The aperture in the lever M2 is open from below so as to permit it to straddle the locking pin or to be disengaged therefrom, but near its inner face the lever is formed with a air of inwardly projecting lips M1 partly dlosin the aperture and adaptedto embrace a xed collar P1 on the locking pin. Normally, thefcollar1 P1 is held within the lipsM1 by a spring j P3, as in Fig. 4, but when the pin is drawn to the right a ainst the action of the spring, the collar is s ifted out of engagement with the lipsv andv passes into the enlarged and unobstructed portion of the aperture, as in Fig. 5, in whlch position of the `parts the lever may clear the pin and be free to be moved upwardly independently of the lever O (see Fig. 6). The locking pin is held iny the latter or inactive position by means of a cam shaped piece P8 fixed thereon and arranged to coperate with a beveled sector plate N fixed to the pivot stud M3, the sector plate being of sufficient circumferential extent to allow the disconnection of the parts in various adjusted positions. The engagement of the piece P3 with the plate N also serves to maintain the ejector adjusting slide F-3 in its set position during the independent operation of the lever M2. The locking pin P is provided with a handle P2 to facilitate its manipulation.

As previously stated, I have shown my invention merely in preferred form'and by way of example and as applied to a specific style of mechanism,. but obviously many modifications and alterations therein, and in its mode of adaptation, will suggestthemselves to those skilled in the art without departure from its scope.
