MOLD LINER FOR TYPE CASTING MACHINES Filed Feb. 21, 1950 INVEN TOR. Joe Barnes.
ATTORNEYS Patented Jan. 20, 1953 UNITED STATES PATENT OFFICE 2,626,044 MOLD LINER FOR TYPE GAS-TIN G MACHINES I Joe Barnes, Columbus, Ohio Application February 21, 1950, Serial No. 145,492
My invention relates to a mold liner for type casting machines. It has to do, more particularly, with a mold liner which is useful on various makes of type casting machines in use at the present time, such as the Linotype and Intertype machines. The invention deals particularly with indicating means on the liner for indicating the point or thickness of the liner and the length of such liner. Type casting machines of the general type indicated are provided with a large number of mold liners of various thicknesses and lengths. In the casting of slugs for type or lines of type with these machines, it is necessary to vary the thickness of the mold spaces to produce slugs of different thickness (point) and also to vary the length of the mold spaces to produce slugs of different length (ems or pica) which will correspond to the width of the column desired.
At the present time, the mold liners are provided with numbers stamped in the outer edge of the liner to indicate the thickness or point and the ems or pica which indicate the length of such liners. It is very difficult for the operator of a machine of the type indicated to read the fine stampings applied to the thin edge of the liner. This is especially true after they have been used on the machine for some time and the fine letters become covered with molten meta1, grease, et cetera. Considerable time of the operator can be saved and the operators efiiciency-can be increased, if the indicia on the mold liner can be read easily and quickly.
It is the main object of my invention to provide a mold liner of the type indicated which has a novel arrangement for indicating quickly to the operator, while the operator is in his usual position, the thickness and length of the mold liner in position in the mold.
Still another object of my invention is to provide indicating means associated with the mold liner which is not only so positioned that it can be readily observed by the operator but is of such a nature that large numerals may be used as the indicia.
Still another object of my invention is to provide a mold liner wherein the indicia thereon is so located that there will be little possibility of it becoming covered with molten metal, dirt, et cetera, so that it cannot be deciphered.
Another object of my invention is to provide indicia means on a mold liner which is so arranged that it will be readily observable but which will not interfere with the normal rotation of the mold carrier.
A further object of my invention is to provide an indicating structure for a mold liner which is extremely simple and will not add any substantial cost to the mold liner.
Various other objects will be apparent.
According to my invention, I provide a left hand mold liner which is adapted to take the place of the usual liner that has the thickness and length indicia stamped on the thin edge thereof. This mold liner is provided with an extension or tab which extends from the end of the mold when the liner is positioned therein. This liner extension or tab is curved in the direction of rotation of the mold-carrying disc and within the circumference thereof so as not to interfere with the rotation thereof. The flat upper or outer surface of the extension or tab is provided with large numbers for indicating the thickness and length of the liner, and conse quently, the thickness and length of the slug to be produced in the mold. The tab or extension is so located that the numbers thereon can be observed readily by the operator from his position in front of the machine although on some models a slight turn of the mold mounting disc is necessary to bring the tab liner into view.
The preferred embodiment of my invention is illustrated in the accompanying drawing wherein similar characters of reference designate corresponding parts and wherein:
Figure 1 is a diagrammatic view illustrating a type casting machine to which my invention may be applied.
Figure 2 is a front elevational view of the moldcarrying disc of the machine with the molds thereon.
Figure 3 is a perspective view of a mold liner according to my invention which is useful on an Intertype machine.
Figure 4 is a perspective view of a mold showing the liner of Figure 3 positioned therein.
Figure 5 is a perspective view similar to Figure 3 and showing a liner according to my invention which is useful on a Linotype machine.
With reference to the drawing, in Figure 1 I have illustrated a type casting machine which may be of any suitable make and which is provided with the usual mold-carrying disc 6 that carries a plurality of molds 1 in the usual manner. In Figure 2, I have illustrated that four of these molds are provided and are arranged chordal to the circumference of the disc 6. The machine shown in Figure 1 is provided with the usual opening 8, which is somewhat enlarged for illustration, in the frame thereof adjacent the 3 disc 6 by means of which the left hand or upper mold liner of the mold, which is in normal or operating position, can be seen. This mold liner is indicated by the numeral 9 in Figure 1.
The mold liner is provided with a body 10 of usual form which, as shown in Figure 4, is positioned between the walls of the mold at the one end thereof and is clamped in position in the usual manner. However, I provide a comparatively long tab or extension I l at the end of the liner which extends a substantial distance beyond the end of the mold. This liner II is curved or angled in the direction of rotation of the mold disc 6 so that it will lie within the circumference of the disc as shown in Figure 2. The extension or tab ll may be provided on its upper or outer face with large numerals I 2 which indicate the thickness and length of the mold cavity that is determined by the thickness and length of the liner. The right hand liner I3 at the other end of the mold need not be provided with indicia as to length and hasnopartin this invention.
It will be noted from Figure 1, that the tab i l of the liner 9 provided on the mold, which is in operative position brought about by rotation of disc 6, will be so positioned that the numerals l2 thereon can be observed readily by the operator sitting in front of the machine or on some models by a slight turn of the disc. The operator can thus, quickly determine by a glance through the opening 8 that the space formed in the mold by the liner will produce a slug of certain predetermined thickness and length.
The liner 8a shown in Figure .5 is exactly the same as that shown in Figure 3 insofar as the indicating means is concerned. The body Illa, however, is slightly different since it is used on a different make of machine. This body Ina is of the character used on a Linotype machine.
It will be apparent from the above description. that I have provided a mold liner for type casting machines which is provided with novel indicating means. The means is so located that large indiciacan be provided thereon and can be seen readily by theoperator. Furthermore, this indicia is so located that it will not become-covered with molten metal, grease, dirt, et cetera, during operation of the machine.
Various other advantages will be apparent.
Having thus described my invention, what I claim is:
1. A mold liner for forming the end of the cavity of a type casting machine which comprises walls'ections spaced apart by mold liners between the ends thereof to form a longitudinal cavity for receiving a slug, said mold liner comprising a body adapted to'be disposed in the end of the mold, an extension adapted to project outwardly from the mold and longitudinally of the'cavity thereof, said extension being provided with indicia on a face thereof for indiciating .tending mold cavity adapted to have a type slug set therein, the mold liner in the leading end of each mold based on the direction of rotation of said disc being provided with an extension which extends longitudinally from the leading edge of the mold in the direction of the length of the mold cavity, said extension being turned inwardly so that it is located within the circumference of said disc, said extension being provided with indicia on the outer face of its inwardly turned portion for indicating the thickness and length of the liner.
.3. In combination with a mold for a type casting machine, said mold comprising wall sections which are spaced apart by mold liners at the ends thereof to form a longitudinally extending mold cavity adapted to have a type slug set therein, the liner positioned at one end'of said mold having an extension on the end of said liner projecting longitudinally from the end of said mold in the direction of the length of the mold cavity, said extension having its projecting end turned downwardly from the plane of the body of the liner and the upper face of the downwardly turned portion thereof being provided with indicia for indicating thelength and thickness of said liner.
