HANS PETERSEN, onDAvENPonT, IOWA, AssIGNon To THE ILINOGRAPH COMPANY, or

' 'DAvENPoRn ToWA, A CORPORATION.

To all whom t may concern:

Be it known that I, HANS PETERSEN, citizen of the United States, residing at Davenport, Iin -the countyof Scott and State of Iowa, have invented certain new and useful j Improvements in Molds for Linotype-'Machines, of which the following is a specifica-- tion.

The invention relates to improvements'in molds, particularly adapted for use in connection with linotype machines.

In the operation of linotype machines, it

, is desirable to cast slugs of a wide variety of sizes to meet various conditions, and heretofore whenever it has beenrequired to change one size slug to another, which frequently happens, it has been necessary for the operator of the machine to substitute liners of sizes different both in width and length for those previously used to make the mold cavity of a predetermined size to produce the desired slug. These changes require considerable time on the part of the operator, as well as a vast amount of labor, and it has also been found that a great variety of equipment must be stored to meet the conditions encountered by the printer.

. The present invention aims to overcome the diiiiculties arising from the use of older types of devices, and in its broadest aspects provides a structure by which the operator may remain seated at practically all times and make the necessary changes with respect to the mold cavity'to adapt the mold for casting slugs of anylength and thickness with but the use of a single laterally adjustl 1- able liner entering the mold cavity from its 'open side. In carrying out the present invention the mold carrying wheel is preferably provided with a series of molds having body cavities tapering fromfront to rear and having channels in the capl portions thereof of differentdepths and tapering in the oppol site direction, as shown in Figure 5, while Ithe mold cavities of thedifferent molds are the same sizes so'that a single liner maybe used for adjusting the portion of the prede:A

termined mold cavity to remain open at the will of the operator, it of course being.. apparent that the deeper the grooves in )the mold cap the wider the finished slug will be.

Application led October 20, 1916. Serial No. 126,765.

-alined with the trimming knives, and these locking devices or pins are inserted within the mold cavity at a predetermined time after the .liner has entered the said cavity so that certain of the locking devices are covered bythe liner, which closes a portion of the cavity. The locking devices obviously prevent any movement of the slug, except when the mold cavity occupies a'position in direct alinement with the trimming knives, at which time suitable automatic means withdraw the locking devices to release the cast slug. l l

l Themold is not only designed to cast slugs of the straight type, but may also be used for casting slugs of the overhang type such as described in my copending application, Serial No. 119,226, as it is apparent that it is often desirable to use the slugs of an overhang type in preference to the ordinary straight slug.

In the accompanying drawings the preferred embodiment of the invention is illustrated, but it will of course be understood that many changes can be made to meet various conditions without departing from the spirit thereof.

. In the drawings:

Fig. 1 'illustrates a portion of the lino- 'type machine carrying the adjustable liner,

with the mold wheel and a mold supported thereby separated from the liner and occupying its normal position just previous to its advance'to casting position. Fig. 2 shows the parts in section when the mold wheel has been moved upon its dowels so that the liner has entered the mold cavity. Fig. 3 showsthe parts of the apparatus in their assembled positions with the mold cav- .i opened to' its extreme length, the mold eel being forward or in casting position and the plunger 13 being disposed within the mold cavity.

Fig. 4L is a detail view of the locking devices and the ac tuating mechanism therefor with parts broken away. i

Fig. 5 is a modified view of the mold wheel in which the same is provided with two molds for producing slugs of different widths.

Fig. 6 is a view of the parts when the mold is in ejecting position, showing plungers or pins withdrawn from the mold cavity.

Fig. 7 is a sectional view showing the mold cavity, the movable liner and its support.

Referring now more particularly to the drawings wherein like reference characters indicate corresponding parts the numeral l designates a movable mold carrying wheel which may be of any approved construction and mounted'with reference to the casting pot in any well known manner. The mold wheel has one or more openingsftherein seating suitable mold portions, each mold comprising a body part 2 and a cap 3 which are secured within the openings in any approved manner, the mold slot being tapered from front to rear, the mold cap 3 having a plurality of oppositely tapering transverse grooves thereln for a purpose which will hereinafter appear. In Fig. 5 of the drawings I have disclosed a view of the mold wheel, in which the same carries a pair of molds each having ribs or grooves therein of different widths so as to produce slugs of a thickness of from 6 to 16 points as the occasion may require upon the proper kshifting of the mold wheel, while the mold cavities are of the same size to be regulated by a single liner 5. The molds, whether one or more be used, are `preferably composed of separable body and cap portions, fastened together or to the mold wheel, or both, with an intervening stationary liner forming a third side wall of the mold cavity. The matrices, not shown, which are disposed adjacent the face Aof the mold when the same is in a position for receiving a supply of metal, may be recessed to produce a slug4 of the overhanging character if desirable, this slug being of a construction such as cast in the apparatus disclosed in my pending application, Serial No. 119,226.

To provide an adjustable ,supporting means for mounting the liner 5 so as to permit the same to be inserted at any desired point into' the cavity of the mold for regulating that portion of the cavity which is to remain open to receive a supply of metal, a stationary portion 6 of the linotype frame has arranged therein an elongated slot or opening 7, provided with an entrance 8 on one side and receiving an angular block 9, having a part disposed within the slot and retained against sidewisevmovenent by frictional conti'ct with the walls thereof and carrying at its outer end an upstanding support 10, receiving the tapering liner 5. The

liner 5 is recessed in its upper and lowersurface so as to eliminate as much friction as possiblewhen the same contacts with the mold cavity as the only portions thereof which engage the walls of the cavity are the beaded or raised edges. The slot 7 is of a relatively great length so as to permit any adjustment of the block 9, which in turn carries the liner 5 entering the open side of the mold cavity and upon the adjustment of the block the length of the cavi-ty may be increased or diminished to form a cavity of a predetermined size.

The grooves in the mold preferably occur at regularly spaced intervals, coinciding with standard printers measures, the unit of which is the pica-em. The grooves in the mold would, therefore, occur either spaced one em apart in multiples or divisions thereof. The liner 5 is at all times carried by the upstanding support 10 which is adjustable and appropriately moved to determine the length of the mold cavity. It will be understood that this forms one of the abutments for confining the line of matrices from which theline is cast; the adjustment may be made in any wellknown manner. It will be understood that some variations in the construction are possible and that, for instance, the opposite matrix` confining abutment. termed the stationary vise-jaw, designated by reference character 24, might also carry a liner similar to that carried by the adjustable jaw in which case the mold proper will consist merely in a body and cap portion separately fastened in their proper position to the mold wheel Without being connected together.

The liner normally occupies thepostion dlsclosed in Fig. l of the drawings, that 1s out of contact with the mold parts, but when it is desired to cast a slug, the liner 5 andthe mold wheel occupy the relative positions disclosed in Fig. 2, at which time the tapered liner is inserted within a portion of the mold cavity and a supply of molten metal is then injected within the cav ity lling the same and casting a slug of a predetermined length and width. The liner 5 is tapered to permit the same to be readily introduced into the similarly tapered cavity from its open end, and in order to prevent any accumulation of dirt' or dust upon the surface of the liner support forming a portion of one side of the mold, ychannels 1l are arranged therein which receive the dust or dirt accumulating around this portion of the mold that would ordinarily prevent a perfect seal between the jaw or liner support, and a portion of one side of the mold.

Arranged Within a cavity in one side of the frame 6 and underlying the block 9, are a plurality ofcoil springs 12, bearing upon the under side of the block, these springs being slightly compressed when the liner is inserted within a portion of the mold cavity to insurel the holding of the y same in itsproper relative position while the lliner enters the mold. When the mold wheel and the linerv are in the relative positions 'disclosed in Fig. 2, that is the mold wheel has been revolved and moved for- .ward so as to permit the liner to enter a portion of one of the mold cavities, a lsupply of molten metal is then forced into the cavity from a casting ,potof any approved construction (not shown),'il1ing that .por-

tion of the cavity las well as the recessed .matrices lying adjacent thereto and the `slight trimming action will at all times producea finished slug, that is rectangular in shape The'mold wheel can carry any number of molds desirable, and in Fig. 5 I have shown the mold wheel as carrying a pair of molds. If a number of moldsare used the grooves therein are of different depths, so that each mold will cast a slug of a different width, but the mold cavities 25 of the different `m0lds are all of'uniform dimensions to permit a single liner to be used for varying the length of any number of mold cavities. i

It is particularly desirable that some means vbe employed for retaining the slugs within the mold during-the withdrawal of the liner therefrom, and to this end I mount upon the mold wheel in any suitable 4Inanner a plurality of plungers 13 passing upwardly through the bodyof the mold andl having attached to 'their lower ends coil springs 14, which sprlngs are also secured to the body of the mold wheel and normallyJ tend to force the plungers upwardly so that their ends are disposed within the mold cavity. As the plungers are ofthe same specific construction and all operate simultaneously a detail description of only one will be given. Carried by the elongated plunger 13 isa wide head 15 Ahaving a rounded face portion to which the coil spring 14 is attached. Suitably mounted upon the mold wheel beneath the body of the mold is a shiftable regulating bar 16 maintained in position by a bracket 17 rig-` idly {itted tothe mold wheel and having upstanding arms 18 to retain this bar against sidewise movement, but to permit a horizontal adjustment thereof. The regulator bar 16 has arranged )therein a plurality of sockets 20, corresponding in number to the number of plungers 13 and normally occupying a position away from the beveled heads carried by the plungers' so that the straight lower edge o the regulatlng bar other plungers are held lowered by the liner if it occupies that portion of the cavity. When the plungers are within the cavity and the linerin an operative position, a supply of molten metal is then injected within the mold filling the recesses in the matrices A (not shown) and casting a slug of the predetermined size. The regulating bar is automatically actuated at a predetermined Atime afterA the mold wheel has moved toward the liner upon its supporting dowels, the liner preventing the entrance of those plungers which would ordinarily enter that part of the mold cavity covered by the liner,

. while the remaining plungers are permitted to enter the cavity. The operating means preferablyv consists of a pair of cams 21 and 22 projecting outwardly from the frame 7 and disposed in different vertical planes. 'Ihemold wheel normally occupies a' position as disclosed in Fig. 1, that is spaced i from its liner, but when the same comes forwardin any well known manner the liner enters a portion of the cavity, and then the cam 22 working in theslot 23 of the regu- 'lating bar pushes the bar so that the openings therein overliethe beveled heads of the plungers, permitting the plungers 13 that do not underlie the liner to enter the mold cavity. W'hen the parts are in this position a supply of metal is injected into the mold cavity and a suitable slug cast.

After a slug has been cast in the mold cavity the mold wheel is then moved back on its dowel pins, withdrawing the liner from the cavity, and during this withdrawing action the plungers 13 retain.v the cast slug within the cavity against the friction caused by withdrawing the liner, and the mold wheel is then revolved past a suitable trimming means for shaping the bottom of t-he slug which is not shown, as'it forms no part of the invention. when revolved until it has reached its normal position, that is t0 say a three-quarter turn from the casting posit-ion, is shown in Fig. 6. At this point the wheel again comes forward on its dowel pins, and during this movement the cam 21 contacts with the .inner edge of the slot 23 in the regulator bar shifting the bar in a direction opposite the movement given the bar by the cam 22, so as tomove the sockets therein out of registry with the plunger heads 15 and withdrawing The mold wheel l the relative. positions shown in the plungers from the cavity to permit the slug to be ejected by a suitable ejector and passed between the trimming knives for a 'final treatment.

Having briefly stated the invention the operation may be described as follows: l

The parts of the mold normallv occupy Fig. 6, at which time the liner 5 is Withdrawn from the mold cavity and the plungers 13 are in alowered position, being retained in this condition by the regulating bar 16. When it is desired to cast a slug, thevmold wheel carrying the mold revolvesa. quarter of a turn to the'position shown in Fig. 1 and thence the mold wheel moves forward on a pair of dowel pins so that the liner 5 enters and closes a predetermined portion of the cavity as disclosed in Fig. 2 and Fig. 3. During this shifting of the mold wheel and after the liner has entered the mold lcavity to such an extent as to overlie the plungers 13, the cam 22 riding within the slot 23 in the regulator bar 16 moves the bar laterally to such a position as to allow the sockets 20 to overlie the heads of the plungers 13 so that part or all of the plungers are then raised by the tension springs 14 and enter the mold cavity. `A supply of molten metal is then introduced into the cavity and a suitable slug cast in that portion of the cavity not closed by the liner. The `mold wheel and mold are then withdrawn from the liner 5, but during this withdrawing action of the mold wheel from the liner 5, the upper ends of the plungers 13 still remain withinl the mold cavity for retaining the slug in place against the friction caused by the withdrawing of the liner on one end of the slug. The mold wheel then revolves past a suitable knife (not shown) which'trims the bottom thereof and the plungers 13 also serve to retain the slug in its proper position during this trimming action and prevent the same from being pushed from the mold cavity. V'Vhen the mold wheel has reached its normal position, that is to say three quarters of a turn from the casting position, it again comes forward on its dowel plus and the cam 21 engages the inner edge of the slot 23 in the regulator bar 16 moving the bar in a direction the reverse of the direction the bar is actuated by the cam 22 and causing the lower edge of thebar to engage the heads of the plunger-S13 and withdraw the plungers from the mold cavity to permit an ejector blade to force the slug from the mold so that it may be passed between the trimming knives.

While the preferred embodiment of the invention has been illust-rated and described, it will of course be understood that the structure disclosed is capable of many changes without departing from the spirit of the invention.
