TYPE-MOLD.

T0 all "Lc/0171, 'it 77mg/ Concern Be it known that we, JOHN SELLERS BAN- cRor'r and Maunrrz C. INDHL, of Philadelphia, in the county of Philadelphia and .State of Pennsylvania, have invented certain new and useful Improvements in rl`ype- Molds; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to improvements in what are known as low quad type molds or such as are adapted to produce both type and spaces or quads the two latter either shoulder high or shorter.

Molds of this class, as heretofore constructed, have been provided with a cut-olf for the upper or character end of the mold cavity, usually in the form of an independently movable section of the mold blade or dimensioning and ejecting member, the latter being formed in two longitudinal sections, superposed the one upon the other, whereof the lower or dimensioning member is connected with the mold adjusting devices, while the upper or cut off member is controlled by selective adjusting means whereby it is either projected beyond the lower section, to close the end of the mold cavity, or sustained in register with the operative end of the lower section, to form a continuation of the side wall of the mold cavity. This arrangement permits the production of two lengths of quads, one shoulder high, resulting from the seating of a blank matrix on the mold with the two mold blade sections alined and subject to the mold adjusting devices, and the other shorter by the thickness of the upper or cut ofi' section of the mold blade, resulting from the projection of the latter into the end of the mold cavity so as to form an end wall therein against which the cast is made. These molds are specially designed for use in connection with automatic type casting and composing machines equipped with a series of matrices adapted for selective individual application to the end of the mold after the manner disclosed in Patent No. 625,998 of May 30, 1899.

In the case of printing type the height of the character above the shoulder is deter- Specicaton of Letters Patent.

mined by the depth of drive, z'. c. the depth of the countersunk depression in the matrix, and in commercial matrices this amounts to .O3 in.; hence it follows that the difference between character type and spaces or high quads, such as result from the seating of a blank matrix in the mold with the faces of the two mold blade sections in alinement, is but .03 in.

Under some circumstances, as when a considerable interval is occupied by quads, this difference is insufficient to prevent smearing by the transfer of ink from the quads to the surface upon which the impression is taken, hence the introduction of the low quad mold whereby the quads are formed of less than shoulder height. It has been found in practice, however, that a length of quad best suited for stereotyping is not so well adapted for other classes of work, such as electrotyping, owing to the fact that the latter requires less depth than the former for the white, the deeper cavities produced by the low quads tending to retain and prevent or retard the drawing of the softer or wax like impression material commonly employed in this process. Moreover, although the cut-off feature of the low quad mold is applicable to the interword spaces as well as the quads, it is not commonly so used for stereotype work on account of the relatively deep and narrow cavity produced thereby which interferes with the proper withdrawal of the flong.

Now it is the object of the present invention to furnish a mold capable of producing, selectively, spaces and quads of three or more diiferent heights and adapted for use in composed matter designed either for direct printing, stereotyping or electrotyping, to which end the mold is equipped with a mold blade formed of a series of superposed longitudinal sections and provided with means whereby the intermediate section or sections can at will be coupled and maintained with its end or casting face in alinement with either adjacent section, the one under the control of the cut-0E or low quad mechanism, and the other under the control of the mold dimensioning mechanism, the arrangement being such that when the several sections are maintained with their casting faces in the same plane they form a side wall of the mold cavity for the production oit either character type or shoulder hiO'h s races or Quads' when the intermediate is held in register with the dimensioning section the upper or outer section responding to the low quad mechanism may be projected to close the end ot the mold cavity for the production ot spaces or quads ot' a height shorter than shoulder height by the thickness ot said cut oit' section', and 'when the intermediate is coupled with said outer or cut ott' section the two will operate in response to the cut ott' controlling devices to close the end ot' the mold cavity for the production ot spaces or quads ot a height less than shoulder high by an amount equal to the combined thicknesses ot the two cutoff sections.

1n the accompanying drawings illustrating a preferred 'form of embodiment ot' the invention Figure 1 is a perspective ot the mold. Fig. 2 is a partial section in the plane oit the mold blade. Fig. 3 is a perspectiie view oi" the tri-sectional mold blade, the sections being` disconnected and. dctached. Fig. Lt is a partial section transversely oit the mold blade, in the plane ot the through bolt. Fig. 5 is a perspective o1 the mold blade with the sections associated together, the upper section being in dotted lines. G is a partial section showing the arrangement ot the adjustable top bearing for the mold blade. Fig. T is a diagrammatic view showing the arrangement of mold blade sections when subject to the mold dimensioning mechanism. Fig. 8 is a similar view in which the upper section is controlled by the cut-ott mechanism for closing the end ont the mold. Fig. 9 is a similar view with two sections of the mold blade under the control of the cut-ott mechanism and the third section subject to the mold dimensioning mechanism.

Lilie letters ot reference in the several iigures indicate the same parts.

llllith the exceptions hereafter noted the mold illustrated is in all essential particulars the same as that disclosed in Patent No. 962,411, dated June 28, 1910, and is adapted ttor operation in connection with the cut-oil controlling and mold dimensioning mechanisms referred to therein.

lt will suffice 'tor purposes of identication to designate some ot' the principal elements oit the prior patented structures such as the base plate 1, side blocks Q, cross block et, main or lower mold blade section 5, upper or cut-ott mold blade section 6, and its carrier 7, latch 8 pivoted in said carrier, and cross head 9.

i-lccording to the present invention there is interposed between the lower and upper mold blade sections 5, G. an intermediate, independently movable section 10 of the same width as the lower section and provided with a bearing 11 for the reception of a Suitable actuating device, the latter represented by a lever 19 pivotally supported on side block 3, and provided with a yielding retainer such as actuating spring 13, whose action on said lever can be reversed, as by detachably connecting its outer end to either of two supports 1-/1 located on relatively opposite sides ot the pivot of said lever. rlhe upper face ot side block 3 is recessed for the accommodation ot lever 12 so that no obstruction is presented to the free movement et the die case above the mold, said recess being bridged by a suitable cover plate, as shown. Lower section is further provided with a gaging member 15 against which the rear end oit intermediate section 10 abats when the inner or casting faces of the two sections are in register (see Figs. 5, 7 and 8) and the intermediate section 10 is also provided with a gaging surface 1G adapted to contact with a complemental gaging member 17 on the carrier 'T when the casting lace ot the upper and intermediate sections (3, 10 are in register (Figs. 7 and 9).

yl`he proportioning and arrangement ot the parts is such that when the carrier T is coupled with the mold dimensioning devices, as through the engagement off latch 8, intermediate section 10 will be clamped and held between gaging surfaces 15 and 1T, with its casting tace or end in register with those of the lower and upper sections 5, (3, (Fig. 7) and tl e mold blade as a whole will be under the control of the dimensioning mechanism for casting character type or shoulder high spaces and quads, said dimensioning mechanism being represented in this case by the cross head 9 and cross pin 21 through which the adjusting and ejecting movements are transmitted to lower section TWhen, however, the cut oil controlling devices, represented by lever 2Q, are brought into action, as by engagement with latch S, the intermediate section 10 will be coupled with and respond to the action ot' either' the cut-ott7 controlling or the mold dimensioning mechanism accordingly as its actuating de vices are set in one direction or the other` Thus, it spring 13 is set to maintain the intermediate section 10 in contact with ing member 15, the intermediate and lower sections will be maintained with their casting faces in register and subject to the action ot the mold d imensioning devices while the upper section G alone responds to the cut-ott controlling mechanism (see Fig. 8) thereby producing a low quad or space, whose length, as compared with the normal or shoulder high space, is determined by the thickness oit' the upper section 6, and its width set-wise, b v the conjoint action ot" the intermediate and lower sections. lllhen, however, the action of spring 13 is reversed` so that it operates to hold intermediate section 10 in engagement with gaglng member 17, the intermediate and upper sections will be advanced in unison in response to the cut-olf controlling devices (see Fig. 9) and the produced space or quad will now be shortened by an amount equal to the thickness of sections 6 and l0. Thus through the cut-off controlling mechanism and actuating devices of the intermediate section it becomes possible to selectively obtain from the same mold spaces or quads of three different lengths and such as are best adapted for the purpose for which the composed matter is designed to be used, whether for direct printing, stereotyping, electrotyping or other purposes.

lt is of importance that the sections of the mold blade should be maintained in sulticiently close contact to prevent the entrance of molten metal into the joints between them during the casting operation, which latter, as usual, is performed under considerable pressure. In the present instance this point is attained through pressure applied to the top guide 23 resting upon and engaging the lower member of carrier 7 and transmitted through the top section 6 to intermediate section l0 and thence to lower section 5, whereby the latter is held to its seat in the mold blade channel.

Having thus described our invention, what we claim as new is:

l. A type mold provided with a casting chamber terminating at one end in a matrix scat and havingl one of its walls divided into a series of independently movable sections superimposed one upon the other in planes substantially parallel with said matrix seat.
