19 Claims.

The present invention relates to improvements in typographical machines, and more particularly to-1ine casting machines of the general class disclosed in U.S. Letters Patent No. 436,532 granted 5;, September 16,- 1890 for producing type bars or slugs-from character bearing matrices, wherein assembled-.lines of matrices, each having a characterin an edge thereof, are clamped endwise between vise jaws and presented to a mold-so that the character bearing portions of the matrices close the casting cavity along the front thereof, molten-metalbeing injected into the mold to cast the type bars or slugs -againstthe matrices and thus formprinting `characters on the front edges .e ofthe slugs.

The invention relates lmore particularly to the matrixlline'clamping jaws` of machines of this class-,and it provides novel means for mounting It-hasalso been proposed to provide a rib pro- Y jectingfrom `the casting face of-a vise jaw in positionfto enter the front of the mold cavity or to otherwise cooperate with the mold, as with a recess in the face thereof, to produce slugs of lowquad height.

Molds having different height casting cavities have also been employedto produce slugs in the different point sizes required in printing, and to correspondftherewithribs of different widths are required on the vise jaws and different size charactersor borders are needed. While the ribsor the characters may be provided on separable or exchangeable slides in the faces of the jaws,` it has been found dicult and costly to accurately t and securely fasten such slides into thejaw-faces and much time is consumed in exchanging them. Moreover, especially in the case ofv ribs intended to enter within the mold cavity or into alrecess` adjacent thereto, it has been foundfimpractical to obtain correct alinement of the lparts to permit their proper cooperation when the moldadvances in the usual manner to effect facewise and metalV tight lock up prior to casting.

f Thisdifficulty arises because of variations in dif- 1935, Serial N0. 18,911

ferent machines and fromA the fact that the vise jaws, particularly if they are movably arranged for quaddng and centering matrixlines, must have considerable freedom or play intheir guides A in order to avoid resistance totheir closing and opening movements.

According to the present invention, means are provided whereby avise jaw which is inuse may be easily and quickly exchangedfor another vise jaw whenever itis necessary to substitute ajaw with a different size rib or character. bearing portion on its casting face and for `adjusting the jaw to properly aline the rib or character bearing portion on` its face with the cavity or recess in the mold. In carrying out the invention, an adjustable intermediate member is provided between the vise jaw andthe usual. jaw supporting block,,this` member being preferably carried by the supportingblock and adapted to receive and locate the jaw thereon and to retain it yieldingly, as by a springpressed locking device which is capable of release to instantly disconnect the jaw from its support andpermt substitution of another jaw having a rib of different size or a casting face of different form. thereon. The present invention thus,V overcomes the disadvantages` attendant upon the use of exchangeable casting slides in the jaws and the adjustment `provided. for the jaw enables perfect alinement of character bearing portions or low-quad castingribs on the faces of the jaws with the mold cavity, or with cooperative recesses in the molds, to be attained when thejaws are employed on different machines.

To these and other ends, the invention consists in certainimprovements and combinations and` arrangements of parts all as will be hereinafter more fully described, the features of novelty being pointed out more particularly in the claims at the end of this specification.

plungerd, the inner end 35er the screw'33 being conicaltoprovidea :bevelle'd surface which surrounds the depression 34 therein and is similar tothe conical :head 25 on .the plunger 24.

The manner of applying the vise jaw to its 'adaptor member, according to the present invention, .is shown clearly in Fig. 5, from which it will be seen that the vise jaw is applied by engaging .the recess 23 therein over the projection `22 .on the adaptor member and then swinging the router end of the .jaw downwardly, whereupon downward pressure on the jaw will cause the conical or bevelled surface 35 on the screw 33 to ycam .theplunger 24 inwardly by engagement with its conical head 25, .thus bringing the depression 34 in the inner end of the screw 33 into alinement and locking engagement with the conical head 25 on the plunger. In order to insure drawing of the jaw rmly into place on the shoulder 22, a tapered pin 36 may be fixed in the upper wall of a recess 31 provided in the jaw to accommodate the locking plunger 24, this tapered pin being arranged to engage against the lug 30 as the outer end of the jaw is swung into locked position, and in order to position the jaw laterally on the adaptor member, longitudinally extending shoulders 38 are provided along the front and rear sides of the adaptor member, these shoulders engaging the inner side Walls of the recess 31 of the jaw as the latter moves into its locked position, thereby alining the face 39 of the adaptor member with the casting face 40 of the vise jaw.

The plunger 24 and screw 3 3 thus comprise cooperating parts to yieldingly and removably lock and retain the vise jaw rmly on the adaptor member and to permit removal of the jaw merely by forcing its outer end upwardly to disengage the screw from vthe plunger. The invention thus provides means for mounting a vise jaw for pivotal movement relative to its support and locking means releasable upon such pivotal move` ment of the jaw to enable disconnection of the jaw from its support for the purpose of exchanging the jaw for another jaw of diierent form, and an adjustable adaptor member for locating and retaining the jaw on its support, which enables the jaw to be mounted thereon in proper vertical alinement on diierent machines and in such position of alinement as to assure accurate engagement of a rib projecting from the casting face of the jaw with a recess in the face of the mold with which it cooperates during a slug casting operation.
