Definitions

  • the present invention relates more particu-- larly to the matrix clamping jaws and. molds of machines of this class and it provides novel cooperative relations between these parts of the machine whereby portions of the printing edges of slugs beyond the type characters thereon will always be cast automatically at a predetermined level which will enable zinc or other forms of printing plates containing cuts or the like, which must stand at the same type height as the characters on the slugs when assembled or made up in the printing forms, to be mounted directly on the slugs, thereby avoiding the necessity of milling off or otherwise reducing the height of the blank portions of the slugs to bring them to the proper height for such purpose.
  • the movably arranged vise jaws are each provided with a continuous rib which projects from the casting face thereof and extends over the entire length thereof, this rib however being wider than the height of the casting slot of the mold instead of equal thereto and engaging with vertical faces on the front of the mold adjacent to the top, bottom and ends of the casting slot and set back from the usual vertical front face of the mold a distance equal to that to which the rib projects toward the mold from the face of the respective vise jaw.
  • the present invention further provides alining rails on the vise jaws to cooperate with the usual matrix alining groove in the mold as an additional means for improving alinement and for aiding in the support of the vise Jaws during justification of the matrix lines.
  • Figure 1 is an elevation of a portion of a slug casting machine equipped with automatically movable vise jaws as viewed from the rear, the vise jaws being provided with the low-quad ribs according to the present invention
  • Figure 2 is a front elevation of a slotted slug casting mold recessed according to the present invention above and below the casting slot to receive the ribs on the vise jaws;
  • Figure 3 is a vertical section on an enlarged scale, taken on the line 3-3 in Fig. 1;
  • Figure 4 is a vertical section, on an enlarged scale, taken on the line 4-4 in Fig. 1;
  • Figure 5 is an enlarged view of a portion of the section shown in Fig. 3;
  • Figure 6 is a view similar to Fig. 4 but showing the relation between the alining rail on one of the jaws and the mold as the latter advances prior to the slug casting operation;
  • Figure 7 is an elevation of a slug cast in accordance with the present invention.
  • I designates a portion of the vise frame
  • 2 designates the mold disk
  • 3 and 4 designate the cap and body of a slug casting mold mounted on the molddisk, the mold having a slot or casting cavity 5 in which the type bar or slug is to be cast.
  • the mold disk may carry a plurality of molds as usual in machines of this class, each mold for example being of a different size to produce slugs of different sizes, and the mold disk is rotatable to bring a selected mold thereon into casting position.
  • the movable jaw or jaws will close the mold slot at the front thereof beyond the end or ends of the matrix line presented between the jaws.
  • different lengths of matrix lines may be presented in front of the mold and the casting slot in the mold may be longer than the matrix line, in which event the closing movement of one or both jaws against the line will cause the casting face or faces of one or both vise jaws to cover and close the front of the mold slot beyond the end or ends of the matrix line.
  • each vise jaw is provided with a longitudinally extending rib l5 or I6 which projects toward the mold from its casting face and is on substantially the same horizontal level with the mold slot 5.
  • the rib l5 or IE on each jaw is preferably formed on a slide II or I 8 suitably secured to the respective vise jaw, as by fitting thereof into a dove-tailed recess in the casting face of the jaw, as shown, and the slide on each jaw also carries or has formed thereon a rail 19 or 20 which is parallel to the respective rib l5 or IE.
  • Each of the rails I9 and 20 occupy the proper height on the jaws to enter the usual matrix alining groove 2! formed in the front face of the mold and to engage the top edge 22 of such groove, and these rails l9 and 20 preferably project from the faces of the vise jaws for a greater distance than the ribs l5 and Hi.
  • the vise jaws are of the same thickness as the width of the body of the matrices as usual, so that the casting edges of the matrices held between the vise jaws will be in the same plane as the casting faces of the jaws, and while a slug is being cast in the mold, the character bearing edges of the matrices and the casting faces of the jaws engage the front faces of the upper and lower mold sections 3 and 4 and form a metal tight joint or facewise lockup therewith while molten metal is being injected into the mold slot to cast the character bearing slug. If the line of matrices between the vise jaws is shorter than the length of the mold slot, the edge of the slug beyond the matrices will be blank due to the casting thereof at one or the other end of the mold slot against the lib dill
  • the function of the ribs l and IS on the vise jaws is to enable casting of the blank portion or portions of the slugs beyond the characters produced by the matrices, at some predetermined height, as for example a height which will enable the blank portion or portions of the slugs to support directly thereon and at the proper printing height a printing plate or the like, the thickness of which is greater than the depth of the character punchings in the matrices.
  • each of the ribs l5 and I6 is of greater width than the vertical distance between the upper and lower walls 23 and 24 respectively of the mold slot, and in order to accommodate the width of the rib beyond these upper and lower walls of the mold slot, longitudinal recess portions 25 and it are provided adjacent to the walls 23 and 2t, throughout the length of the front faces of the respective upper and lower mold sections 3 and t, as shown in Fig. 2.
  • These recess portions are of the same depth from the faces of said mold sections as the distance to which the ribs lb and iii project from the faces of the vise jaws, and they present vertical faces 21 and it which cooperate with the faces of the ribs to and it on the vise jaws.
  • the mold liners 2d and it which space apart the upper and lower mold sections 3 and d and define the ends of the mold slot, and which liners may be either separate members inserted between the upper and lower mold sections or part of one or the other section, are set back from the front face of the mold the same distance as are the surfaces fl and it from the front face of the mold, so that the vertical front edges of these liners, in conjunction with the vertical faces 2i and 2b which lie in the same vertical plane therewith, form a recess which extends entirely across the front face of the mold and closes the bottom of the recess beyond the ends of the mold slot and will be engaged by and will form a metal tight fit with the vertical faces on the ribs it and it.
  • the upper and lower walls of the recess portions lb and it may be beveled or inclined at opposite angles as shown and the upper and lower edges of the ribs it and it correspondingly beveled, or these walls of the recess portions may be perpendicular to the face of the mold in which case the upper and lower edges of the ribs lb and it would also be perpendicular to the faces of the jaws, but in any case according to the present invention it is intended that these walls of these recess portions present an opening at the front of the mold which is somewhat wider than the ribs iii and it in order to permit free entry of said ribs and permit the vertical faces of the ribs it and it above and below the walls fill and f t of the mold slot to engage the vertical faces fl and it of the recess at the front of the mold and thereby form a facewise metal tight lock up at the front of the mold slot beyond the matrices.
  • the blank portion or portions of the slug beyond the matrices will be devoid of such fins since the projecting ribs iii and it on the vise jaws completely close the mold slot at the front beyond the matrices by metal tight engagement of the vertical faces of the ribs against the opposed vertical faces fl and it of the recess in the mold and by similar metal tight engagement of the vertical faces of the ribs i b and it with the opposed vertical front faces of the mold liners ft and lit.
  • These fins thus cast on the slug will be trimmed off when the slug is ejected forwardly out of the mold and through the usual side trimming knives commonly used in machines of this class.
  • ribs lb and it on slides Ill and it removably mounted in the respective vise jaws may be employed having ribs iii and it of different widths to suit mold slots of different heights for casting slugs of different point sizes, but it will be obvious that since it is necessary only for the vertical faces of the ribs lb and it to seal or close the mold slot at the front by engagement with the vertical faces fl and it and the front edges of the liners which close the bottom of the recess which extends entirely across the front face of the mold, a rib of given width on the face of each jaw may be used with several different height mold slots.
  • alining rails on the vise jaws to cooperate with the usual matrix alining groove in the mold as the latter advances against the matrix line in the usual manner assures alinement of the upper and lower edges of the lowquad casting ribs on the jaws with the upper and lower walls of the recess in the mold before the ribs enter such recess.
  • the ribs on the jaws are narrower than the recess in the mold, it is desirable that the clearance between the edges of the ribs and the upper and lower walls of the recess be made as small as possible in order to prevent escape of molten metal at the points where the jaw faces contact with the end matrices of the line, and such is made possible by the present invention.
  • the engagement of the alining rails on the jaws against the top edge of the alining groove in the mold prevents tipping of the vise jaws endwise under the influence of the upward drive applied to spacebands in the line during justification thereof.
  • a slotted slug casting mold having a recess extending across the face thereof longitudinally of and intersecting the mold slot, and a pair of vise jaws movable longitudinally of the face of the mold and having casting faces cooperative therewith, at least one of said jaws having a continuous longitudinally extending rib projecting from its casting face to cooperate with said recess in the mold face.
