LATE NEWS PLATE CASTING- MACHINE Application filed January 19, 1927, Serial No. 162,116. Renewed March y16, 1931.

This invention relates to the casting of late news plates which are to be inserted in the ordinary stereotype plates for printing articles of news which come in too late tobe incorporated on the regular printing plates.

The principal objects of the invention are to provide a method of casting these late news plates which will avoid the necessity'of having a linotype operator make up as many duplicate slugs of the late news device as there are duplicate printing plates usedin the edition; to provide means whereby these late news plates can be castin a manner similar to the usual stereotype printing plates but I" with a small casting machine capable of producing more than one plate at an operation, when desired; to produce means whereby the said casting machine is operatedautomatically for this purpose; to provide means for holding a plurality of matrices in the concave back of said casting machine; to provide means for loperating two complete sets of matrix clips therein, and to provide means for ejecting the plates automatically one after the other with the rotation of the core or cylinder and sawing off the tails.

Other objects andadvantages of the invention will appear hereinafter. Reference is to be had to the accompanying drawings in which f Fig. lis a plan of a late news "platecasting device constructed in accordance with this invention showing the parts in position for performing the casting operation;

Late news is generally printed on a portion of the newspaper which is left blank for that purpose and reserved for news that comes in too late to be cast into the regular printing plate. The late news device therefore has to be made up with the greatest possible economy of time and effort at the last momentY before going'to press.V Each oneis set up by a linotype operator and these linoy type slugs constitute the printing surface ofv Each one' Under present vconditions the larger newspapers are printed in such great editions that it is necessary to have duplicate plates and cylinders for the same .edition of the paper. In such cases it is necessary for the linotype operator to make up just as many sets of slugs for the late news-as there are duplicate plates for use in printing the papers. This causes a waste of time just when time is most valuable7 that is, the last period before going to press.

The purpose of this invention is to make up a single linotype slugas a master; the same as in the preparation of a regular 'stereotype plate. From this a matrix is made as in the general process of stereotyping. VAs many of these matrices may be made as are necessary. They are used tov cast late news plates ofv less than pagesize which areto be used in connection with the usual plates with lblank spaces that are made'up for their'insertion as the news comes in. This reduces the time required by the linotype operators and isl of very great value for thereason that the'press has to waitonly for a single set-up by the linotype operator and then for the casting of as many of these partial late news plates as .may be desired. v Y

On account of the customary size of the late news section I lfind it possible to cast two'late news plates against the periphery of the cylinder or core. vThis cylinder is of the usual this invention whichcomprises a frame or bracket 10 fastened to the side of a melting furnace 11. The furnace, of course, is provided with the usual melting pot and may be provided with any desired means for filling the mold. This bracket 10 is pressed against the furnace by a foot 12 and supports the entire machine. Y

The power is supplied from any desired source to a driving gear 13 mounted on a shaft 14 supported in bearings on this bracket 10. This shaft has a worm 15 thereon driving a gear 16 located on a vertical shaft 17 supported by the bracket 10. On. the shaft 17 is a cam 18 havingv a cam groove 19 for receiving a roll 2O which is adjustably fastened to a shelf 21 which projects out rearwardly from the casting back 22 forming-a part of the mold.` This back and shelf are mounted to slide in a rectilinear direction, being guided in ways or guides 23 on the bracket 10. The cam groove 19 is so designed that for a major portion of the cycle7 that is for one rotation of the shaft 17, the casting back 22 is forward in casting position permitting the plate to be poured and cooled. It is also equipped with a low portion which withdraws the back 22 and holds it in that-position. During this portion of the cycle a gear 25 on the bottom of a journal 26 which supports and carries with it the casting core 27 is rotated by a segmental set of gear teeth 28 fixed to the gear 16. This segment 28 has just enough teeth on a portion of its periphery to cause the cylinder 27 to rotate through a half revolution and come to a stop when the groove 19 is ust ready'to cause the back 22 to advance into position for casting more plates. On the f shelf 21 are two vertical shafts 29 on which are fixed casting bar levers 30 at opposite sides. On these shafts are arms provided with cam rolls 31 operating in cams 32 fixed to the` Guides 23. The motion of the box 22 toward and from the casting position swings the levers to cause the casting bars 33 to open and close, as will appear from a comparison of Figs. 1 and 2. This is for the obvious purposes of opening and closing the opposite edges of the mold formed between the back 22 and the cylinder 27.

rFhe matrices are clamped in the box by means of a removable vertical bar 35 in the center which'engages the adjacent edges of two matrices and clamps them in place against vertical rods 40. The bar 85 is moved up and down by a hand lever 34. V Two matrix clips 36 clamp the matrices on their outer edges. These clips are moved toward and from clamping position by means of handles 37 pivoted on studs 38 at the extreme vedges of the casting box. The handles carry pins 39 entering horizontal slots in the clips. These pins cause the clips to move up or down as the handles are operated. The

` stads 3S acting in inclined slots 41 cause the clips to move into clamping position as shown in Fig. 1 or to recede from the matrix when the handles are pulled up.

It will be seen that I have Shown two matrices M clamped in position in this way. These matrices cover an arc of less than 90 degrees and in fact considerably less. On account of their small curvature no means has to be provided for stripping the matrix from the plate when the casting box is open. It will be understood, however, that they are of the same kind as the matrices used in casting full plates, but the whole mold is much shorter.

The cylinder 27 is provided with one or more circumferential grooves 44 in which fit rings 45 which are stationary. These rings are provided with strippers '46 that project toward the core or cylinder 27 and strip the plates and tails. The strippers are carried by the fixed guides 23 and in turn support the rings 25. Ihave shown two of these rings and strippers, one for the plate and the other for the tail. They pry the castings away from the cylinder if there is any tendency for them to stick to it. On the cylinder 27 are recesses 27a into which project tongues or ridges from the tails of the casting plates to hold the tails in place on the cylinder after they are sawed'off. Y

The cylinder is cooled by means of apipe 48 delivering water to two orl more pipes 49 which are open at the bottom. They admit water into a trough formed by the side of the cylinder 27 and a cylindrical partition or jacket 50 centered inside the cylinder. When this space is filled, the water flows over the top of the acket and escapes through a passage 51 in the bottom into a chamber 52 and then through an outlet pipe 53.

For the purpose of cutting the tails from the plates I provide a tail cutting saw 55 on a vertical 'shaft 56 .rotated by bevel gearing 57 on the shaft 14. This saw rotates constantly and in contact with the cylinder so that as the'- plates are delivered by the rotation of the cylinder the saw will cut all the ris-ers from their respective plates. Then both tails and plates are separated from the cylinder by the strippers 46.

This machine will castas many duplicate late news plates of standard thickness as may be desired from matrices' molded in the ordinary way from a single set-up of linotype matter. molded for any run. By the use of these matrices this machine rapidly produces a large number of plates therefrom effecting obviouslya great saving of time. The use of two plates of less than 90 degrees arc in the width on one half of the cylinder does not require the stripping of the matrices from the plates when the box is open. This is because the plates do not go half way around the cylinder and consequently do not cling to it.

Only one or two matrices need be The strippers are used to be sure to separate the plates and tails if they adhere to the surface of the cylinder.

It will be seen therefore that these late news plates can be cast with sufficient sped so that the late news matter can be provided as fast as it can possibly be needed in the last period before going to press. Furthermore all the plates will be alike and not dependent upon a new set-up of the linotype matter,y at any time. The linotype operator usually can take a little more time than heretofore, thus increasing his accuracy.

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is l.
