Specification of Letters Patent.

Patented May 24, 1910.

Application filed J'uly 26, 1906. Serial No. 327,912.

To all whom it may concern:

Be it known that I, EVERETT S. DUNA- VANT, of Louisville, county of Jefferson, State of Kentucky, have invented a certain new and useful Improvement in Molds and Operating Mechanism for Type-Machines; and I 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 the figures of reference marked thereon.

This invention relates moie especially to the class oftype molds employed in connection with automatic type casting and composing machines, such as the monotype, wherein a series of matrices is arranged for the separate and successive application of its members to a single body-mold, the latter provided with means for regulating or adjusting the size of the cavity to correspond with the character or space designated by the selected matrix, and it has for its principal object to so increase or enlarge the capacity of the mold that either short or full body types may be produced as desired.

To this end the invention consists broadly in equipping the niold with a plurality of independently movable mold blades arranged in juxtaposition between side blocks, the casting face of one mold blade of normal or full height and that of the other of shorter height and operating beneath an overhang or projection on the side block, the arrangement being such as to present two available mold cavities of different capacities, the one of full longitudinal dimension, open at one y end for the reception of the matrix and dimensioned laterally by the adjustment of the primary or long face inold-blade for character or full body type, and the other closed at one end by the overhang, the latter constituting the end wall, and dimensioned laterally by the short face or supplemental mold blade, for short body space type or quads.

The invention also includes means for selectively setting the mold for either variety of type and for automatically controlling said selective means.

It also includes minor features pertaining to the construction and arrangement of parts all as hereinafter fully described and pointed out in the claims.

In the accompanying drawings illustrating a preferred form of embodiment of the invention specially adapted for use in connection with one of the monotype machines.

Figure 1 is a vertical section of a portion of the type casting and composing machine, with the improvements applied thereto. Fig. 2 is a top plan view of a portion of the machine including the mold and substituted type carrier. Fig. 3 is a sectional view of the mold. Fig. 4 is a detail perspective showing mold blades in position for character type. Fig. 5 is a similar view of the mold arranged for short type or quads. Fig. 6 is a top plan view of the mold blade actuating devices including part of the type machine with which they are immediately connected. Fig. 7 is a detail perspective of the mold detached, t-he cross-block being omitted. Fig. 8 is a top plan view of the transfer motors. Fig. 9 is a top plan view of the control valves for the transfer motors. Fig. 10 is a vertical section of the control valves, Fig. 9. view showing the air connections.

Corresponding numerals in the several figures designate like parts.

For purposes of illustration the invention is shown applied to the machine of Patent No. 633,088, dated Sept. 12, 1899, to which reference may be had for a full disclosure of its construction and operation.

It will suiice for present purposes to refer only to those parts with which the iinprovements have direct connection, such as lever 105 for transmitting the ejecting movement to the mold-blade; adjustable stop rod 116 for gaging the position of the moldblade when retracted for dimensioning the mold; type carrier slide 217 and cross-bar 323 of the pneumatic controlling system. In addition mention may be made of the two way movable die case 26 provided with a series of matrices and operating to present any one opposite the mold; the centering pin 41 for clamping the selected matrix upon the mold while the cast is being made,

and the movable pump nozzle 7 8 through' which molten metal is injected into the mold.

Fig. 1l is a diagrammatic The numerals heretofore given are those found in the prior patent designating corresponding parts.

The mold 1, aside from the improvements to be described, may be of any approved construction, such as that shown, provided with side blocks 2, 3, movable mold blade 4, and a movable cross-block 5. The form illustrated is substantially that of Patent No. 752,814, dated Feb. 23, 1904, but, as will be apparent, other constructions are admissible.

Heretofore the mold has been equipped with a single mold blade herein denominated the primary mold-blade, and when a blank matrix was presented and clamped upon its open end the space or quad cast would of necessity be shoulder high, that is, it would be the full length of the mold cavity and shorter than character type by an amount equal to the depth of the drive only.

As the drive is necessarily shallow and the blank type are not subjected to the same pressure, in printing, as the character type, a slight longitudinal movement suffices to bring their ends into the plane of the printing surface, resulting in an undesirable marring of the printed impression. Attempts have heretofore been made to overcome this defect by constructing the mold-blade in sections, superposed one upon the other, and providing means whereby, when character type were to be produced, the two sections would be locked together and thus caused to operate the same as the integral mold blade; but when blank type were required, the upper section would be advanced to close the end of the mold, and the type cast against the Linder face of the projected section would be shortened anv amount equal to the thickness of the projected part of the upper section. It has been discovered, hovever, that similar and equally good results can be secured and without otherwise interfering with the normal functions of the machine by the introduction of a second or supplemental mold blade alongside of the primary inold-blade thereby providing separate mold cavities for character type and short quads or space type, which end is attained as follows: The side blocks 2, 3, being set or adjusted to present an opening double the thickness of the primary mold-blade 4, a second or supplemental mold-blade 6 is inserted beside the first. The casting face or end of this supplemental mold-blade is somewhat less than shoulder high, that is, it is cut away or reduced on its upper edge below the matrix receiving surface of the primary mold blade 4, the deficiency being supplied by a projection 7 formed upon or secured to the side block 2. The underside of this projection 7 is fitted to the upper face of the supplemental mold blade 6, with the side next the cross-block in the plane of the contacting face of the latter or parallel thereto, and the face next the primary or normal mold-blade 4 in the plane of the contacting faces of the two mold-blades, the object being to form metal tight joints between said projection on the one hand and the supplemental mold blade, primary mold blade and cross-block on the other.

The parting line of the two mold-blades is preferably located in a plane bisecting the jet opening 8 so that metal may be injected in front of either mold blade while the other is maintained in its extreme forward position. As thus arranged if the supplemental mold blade is advanced beneath proj ection 7 until its casting face contacts with the cross block, and it is there held, its side next the primary mold-blade 4 will serve in lieu of the side block 2, to form one face of the mold cavity in front of the primary mold-blade and of which the latter constitutes the dimensioning element. The mold is now in condition to form full body or character type in the usual manner, that is to say, the cross-block being in position, the mold-blade 4 adjusted and the selected matrix clamped, molten metal is injected through the jet opening, after which the primary mold-blade is advanced flush with the cross-block and the type -ejected into the carrier. When, however, it is desired to cast a low body space type or quad, it is only necessary to retain the primary moldblade 4 in its forward or ejecting position and adjust the supplemental mold-blade for dimensioning purposes, so that when the molten metal is injected the type will be cast within the cavity now formed in front of the supplemental mold blade 6 instead of the primary mold-blade and of which the overhang or projection 7 constitutes one end wall. lt is evident that the type thus cast will be shorter than any blank cast in front of the primary mold blade, and that the degree will be determined by the thickness of said projection or the remoteness of its under face measured from the plane of the matrix seat on the mold. It will thus be seen that the mold is provided with a single casting chamber divided into two longitudinal operating sections or portions, the one competent to produce short body type as defined by the end wall and covered by the movement of the supplemental mold-blade and the other competent to produce long or full body type and defined by the opening for the reception of the matrix and covered by the movement of the primary mold blade.

Various forms of mechanism may be applied for controlling the relative positions of the two mold blades and applying the dimensioning adjustments to either, as required, and the preferred form illustrated by way of example is specially adapted to the requirements of the particular machine, to the end that the designating action may be derived from the same perforated strip which controls the other mechanisms. To this end each mold blade is separately coupled with the prime mover of this branch of the machine, to wit, lever 105. It is to be borne in mind that in the machine of the prior patent this lever is moved to advance the mold blade for ejectingr the type, and, on its return, deposits the mold-blade against the previously adjustable stop rod 116 for dimensioning the mold for the next cast.

Lever 105y is connected through a double compression member (such as a rod 9 carrying cross pin 10 located between opposing spring 11 on sleeve 12) with two transmitting members, such as levers 13. Each lever 13 engages one of two slides 14 arranged to abut against the stop rod 116 or a cross head applied thereto, and each slide is in turn coupled with one of the mold-blades,- as by a pivoted member 15 provided with a projection. 16" for entering the cross-pin hole 17 in the mold blade, a spring 18 serving to hold said pivoted member Ain engagement and permit its withdrawal for the removal of the mold. The means described are substantially duplicates of the single actuating mechanism of the prior patent, and are competent to transmit the ejectin-g and adjusting movements to the two mold-blades separately, hence it is only required that competent means be supplied for holding either mold-blade in its extreme forward position, to fully develop the functions of the mold controlled by the other mold-blade.

Although, as is obvious, manually controlled shifting and locking devices might be applied for' positioning and holding one mold-blade stationary while the other remained in action, the preferred plan is one in which this locking action is automatically performed, and, by preference, by the controlling record strip of the machine. Such a mechanism is illustrated comprising a motor and locking pin for each mold-blade, and a valve mechanism controlled by a perforation in the record strip for admitting pressure to said motors alternately as required, the arrangement being such that the motor connected to the supplemental moldblade is normally under pressure and its locking pin engaged, to advance the supplemental mold-blade and hold it in position against the pressure of retracting spring 101 and one spring 11, so that the primary moldblade may be operative for casting full body or character type of different dimensions; and when a short body type is to be formed, the special perforation in the record strip, by admitting pressure to the motor devices of the valve mechanism, will cause the latter toy transfer pressure to the motor of the primary mold-bladel and release the supplemental mold blade so that the former will in turn be locked and the latter released and brought into action. pposite each transmitting member 13 is arranged a motor consisting of a cylinder 19 and piston 20, the

latter in position to engage its member 13- a locking pin 22 carried by or coupled with a piston 23 whose cylinder is in open co-mmunication with the cylinder 19 of its motor j so that when pressure is admitted to the motor the pin 22 will be projected to lock and hold the transmitting member 13, and

with it the mold-blade connected therewith,

in its forward position. The motor of the locking pin is also provided with means, such as` retracting spring.23*, to assist in its withdrawal. Means are also provided for designating which mold-blade shall be locked and which adjusted in connection with each cast made, that is to say, for determining whether the type shall be of the `long or short body variety. In the preferred construction this function is performed by a valve mechanism provided with two passages 24E, 25, each leading from the source of pressure to one of the motor cylinders 19. Each passage 24, 25, is controlled by a valve 27 or 28 adapted to intercept the flow of air and open an exhaust when in one position, and close the exhaust and admit pressure when in another position. The two valves 27, 28, are connected for simultaneous movement through lever 29, and one of them, 27, is provided with a retracting spring 30 and motor, the latter represented by the piston end of the valve working in a cylinder 31 communicating, through duct 32, withhthe port 33 of cross bar 823 with which the special signal perforation cooperates.

Normally valve 28 stands with the passage 2-1 open, thus admitting pressure to the motor of the supplemental mold-blade and holding the latter in its forward position with the locking bolt engaged, while valve 27 closes the passage 25 leading to the motor of the primary mold-blade and opens exhaust passage 34, thus reducing pressure in said motor and permitting the withdrawal of its locking bolt, leaving the primary mold-blade free to respond to its actuating devices. This condition is maintained so long as port 33 is retained closed by an imperforate section of the record strip and pressure is thus withheld from the valve motor 31. The special perforation in line with port 33 is usually associated with those for the spaces or quads, although it may be used in connect-ion with any type signal, in which case it will operate to extinguish the character designated thereby. lVhen said special perforation is brought into registry with port 33 pressure will be at once adj iso shifting of valves 27, 28, so as to admit pressure to the motor of the primary moldblade, thus advancing and locking the latter, at the same time opening exhaust passage 34 and closing supply passage 2l, thereby taking off pressure in the motor of the supplemental mold-blade and permitting the withdrawal of its locking pin so that said supplemental mold-blade will be responsive to its actuating devices.

lnasmuch as the use of the double mold construction herein described involves a delivery of the type at either of two adjacent points in the travel of the type carrier it is obvious that the capacity or range of the latter should be correspondingly increased which can readily be accomplished by so proportioning and adjusting' the clamping members of the type carrier that when presented in front of the mold, in position to receive the type delivered by either mold blade, they shall open suiiiciently to uncover both mold cavities.

The preferred form of type carrier shown is that illustrated in Patent No. 625,998, dated May 30, 1899, minus the diagonal rib for elevating and depressing it, as these movements are not included in the machine illustrated.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is
