LOW-QUAD MOLD FOR TYPE-MACHINES.

Specification of Letters Patent.

Patented June 28, 1916.

Application filed June 3, 1809. Serial No. 499,951.

To all whom it may concern:

Be it known that we, JOHN SELLERS BAN- onorr and MAURrrz C. INDAHL, of Philadelphia, county of Philadelphia, State of Pennsylvania, and useful Improvements in Low Quad Molds for Type-Machines; 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 of reference marked thereon.

The present invention relates to improvements in molds for type machines and espe cially to the class known as low quad molds for automatic type casting and composing machines, and it'consists in the construction, combination and arrangement of parts hereinafter fully described, the novel features being pointed out in the claims.

In the accompanying drawings illustrating a preferred form of embodiment-Figure 1 is a perspective view of the mold. Fig. 2 is a rear end elevation. Fig. 3 is a transverse vertical sect-ion on the line y-y, Fig. 6. Fig. 4 is a vertical section on the line 3-3, Fig. 6, uniting the point block. Fig. 5 is a partial sect'on corresponding with Fig. 4, omitting the main or lower mold blade section. Fig. 6 is a horizontal section on the line 20 02, Fig. 2. Fig. 7 is a view in perspective of several parts of the mold detached and separated one of the side blocks, the mold blade, and some of the screws being omitted. Fig. 8 is a perspective view of the main or lower section of the mold blade. Fig. 9 is a perspective of the upper or cutoff section. Fig. 10 is a perspective of the head for the cross-pin. Fig. 11 is a perspective of the cut-off section looking from the end and side opposite Fig. 9. Fig. 12 is a detail sectional view through the front stop or gage. Figs. 13 and 14 are diagrammatic views showing the-jet slide in two positions of adjustment.

Similar numerals designate like parts in the several views.

To the base plate 1, provided with the usual nozzle seat and jet opening 2, is adjustably secured an integral squaring block 3, the latter furnished with accurately dressed gaging surfaces 4 in planes at right have invented certain newangles to receive the side blocks 5, 6. The squaring block 3 is secured to base plate 1 by bolts passing through elongated openings permit-ting adjustment, the latter being effected through the agency of two or more pairs of screws 7 8, the members 7 of one set entering the squaring block with their heads overlapping and engaging the base plate and those of the other set 8, entering the base plate and overlapping the squaring plate in a manner well understood. To the base plate 1 opposite and in parallel with the inner edge of squaring block 3 is erected the front abutment, prefenbly constructed in superposed sections 9, 10, the upper section 9 overhanging or projecting beyond the lower section on the inner side thereof to form a top bearing and provided with a longitudinal recess for the reception of a shoe 11, the latter backed up by adjusting screws 12. Side blocks 5, 6, are adjustably secured to squaring block 8 in the angle be tween its gaging surfaces 4, as by screws 13, the inner edges of said blocks overlapping the inner edge of squaring block 3, as indicated in Figs. 1, 4, 6 and 7. The crossblock 14 has attached to the side next the front abutment 9, 10, a wearing plate 15 provided with a lateral off-set or rib 15 Figs. 1, 4 and 6, projecting beneath and engaged by the overhanging portion of abutment section 9, and to the lower surface of said cross-block are secured the jet blocks 16, Fig. 7 the latter extending beyond the cross-block and contacting with the inner edge of the squaring block 3 beneath the overhanging portions of the side blocks. The jet blocks 16 are disposed in sequence longitudinally of the cross-block and separated to form a transverse channel for the ejector blade 17, the end of said channel next the squaring block constituting the jet opening through which molten metal is injected into the mold cavity above. As thus constructed and arranged the cross block is maintained in working contact with the side blocks by adjustable shoe 11 and is held down to its seat on the base plate 1 on op posite sides, that is to say, by its engagement beneath side blocks 5, 6, on one side and by the top bearing furnished by section 9 on the opposite side, whereby lateral tilting of the cross block in a direction to open the joints in the mold cavity between the side blocks and cross block and the consequent distortion of said cavity by throwing the face of the cross block out of parallelism with the mold blade is prevented.

The gate pusher 17 is grooved in its lower edge to receive the cam 18 fast on the base plate said cam operating, as the cross block is reciprocated, to effect a longitudinal motion of the gate pusher for discharging the gate. Heretofore the base plate was perforated to form a passage for the gate when discharged by the pusher, but it sometimes happened that the gate or jet would become lodged in the passage and obstruct the cross block, besides which the presence of said opening in the base plate complicated in a measure the ever present problem of compensation and adjustment incident to variations in temperature. These defects have been cured by cutting away the corner of the squaring block 3, as at 19, Figs. 6 and 7, and recessing the base plate 1, as at 20, and locating the off-set section of cam 18 in such relation that the gate or jet will be dis charged in rear of the shoulder 21, so that should the jet hang up or adhere to the cross block it will be engaged and removed by shoulder 21 upon the return of the crossblock, and be discharged over the edge of the base plate instead of through the latter. Side blocks 5, 6, are spaced as usual, to form the mold blade channel, by an interposed gage, 2'. 6., point block 22 corresponding in thickness with the point dimensions of the bodies of the type to be produced, a tie bolt 23 assisting in retainin the blocks in contact with the point bloc The lower or main section 24 of the mold blade does not differ essentially, save as to height, from the integral mold blade ofthe prior art, and is provided with the three regular openings to-wit 25 for the point block 22, 26, for the front stop 27 and 28 for the cross pin 29, the latter carried by the cross head 30 of the mold blade adjusting devices or mechanism.

The principal improvement in the mold blade resides in the equipment and application of the upper or cut-off section 31. The operating portion or that part overlying the casting end of the main section and occupying the upper portion of the mold blade channel adjacent the mold cavity is necessarily of reduced dimensions and liable to be displaced or sprung and thus open the joint between it and the main section, to the serious impairment of the functions of the mold blade.

Owing to the fact that the die case has its movement in close proximity to the top of the mold it is not permissible to materially increase the height of the latter as by the application of superposed guiding devices for the cutoff section, consequently attempts have been made to control said section from below the upper surface of the mold and in rear of the side blocks, either by providing a beveled lateral extension on the cut-off section and a complemental undercut guide on the side block, by providing said section with a. vertical extension or web in parallel with the main section in rear of the side blocks; by reducing the lateral dimensions of each section to one half or less of the width of the mold blade channel and disposing the reduced portions side by side Within said channel; or by combinations of the above. There are objections to each of these schemes. The beveled side bearing is both difiicult to make and to maintain in adjustment; the narrowing of the main section for the accommodation of the dependent web of the cut-off section not only increases the difiiculties in the way of fitting but it also diminishes the strength and rigidity of the main section and its bearing in the mold blade channel; while the hearing afforded by the vertical extension of the cut-off section in rear of the side block is too remote to be completely effective unless an excessive degree of pressure is applied such as tends to retard the free movement of the cut-off section relatively to the main section.

The foregoing as well as other inherent defects in the prior structures, have been overcome by the following construction. The upper or cut-off section takes its bearing upon the upper edge of the main section, to the full Width of the latter, from the casting face to a point in rear of the point block opening 25, Fig. 4, "and said section is attached to a carrier 32 of substantial proportions, the latter disposed to one side of the mold blade channel and guided to reciprocate in a way formed between side block 6 and main section 24 of the mold blade. Cut-off section 31 and carrier 32 may be integral; but it is preferred to form the cut-off section with a lateral flange or rib 33 the latter fitted and fastened to the top surface of carrier 32 to permit a carrier of standard dimensions to be used in connection with cut-off sections of different point dimensions.

To afford an extended bearing for the rear end of the mold blade, squaring block 3 is provided with a rear extension or offset portion 34, the upper face of which is in a plane below but parallel with the top surface of the squaring block, 71. 6., the lower surface of the mold blade channel. The rear end of carrier 32 is off-set as at 35 to take a bearing upon said extension 34 and is supported laterally between two adjustable guides or plates 36, 36*, secured to extension 34. Plate 36 extends beneath and serves as a support for the rear end of main section 24, and it is mainly to permit the passing of this side guide or plate 36 that the surface of off-set 34 is depressed and the carrier provided with the downward extension or foot to which reference has been made. As thus constructed the so-called squaring block aifords gaging surfaces in fixed relation by means of which the side blocks are accurately positioned and held and the mold blade supported both within the mold blade channel and in rear thereof beneath the point of attachment of the mold-blade actuating devices, and by forming said gaging and supporting members as integral parts of a squaring block the rigidity of the mold is correspondingly increased and liability of distortion by variations in temperature under conditions of use is diminished.

Carrier 32 is also provided with a gage block 37 projecting through the front stop opening in the main section and in rear of front stop 27, said gage block contacting with the rear wall of the front stop opening 26 to aline the casting faces of the two mold blade sections for casting full body type. The outer end of gage block 37 contacts with a bearing 38 conveniently located on front stop 27, to assist in preventing the lateral displacement and tilting of the rear end of.

carrier 32.

The rear inner face of side block 6 together with the rear abutment on squaring block 3 are cut away or recessed as at 6 and 3, respectively for the accommodation of carrier 32 said recess in the side block surrounding a section 41 in the plane of the side wall of the mold blade channel against which the point block contacts, the carrier being recessed as at 39 for the passage of section 41. Side block 6 is also provided with a detachable cover plate 42 the inner edge of which abuts against cut-off section 31 above its point of attachment to carrier 32.

The top bearing for the mold blade as a whole is applied to the cut-0E section through its carrier 32, as follows: The carrier is recessed on the side next block 6, to provide a longitudinal bearing 43 to receive the top bearing 44 in the form of a flanged shoe supported upon the inner end of a bolt 45 whose outer end is fastened in a recess in side block 6. The inner portion of the recess is larger than bolt 45 and the latter is engaged at an intermediate point in its length by a set screw 46, operating to flex the bolt and cause its inner end to press top bearing 44 into contact with the complemental bearing 43 on carrier 32, thereby holding the cut-01f section in contact with the main section and the latter to its seat in the mold blade channel, the pressure being direct and extending the full length of the cut-0H section. A spring 47 interposed between top bearing 44 and side block 6 serves to hold the former to position and at the same time presses carrier 32 toward main section 24. To the rear end of carrier 32 is pivotally attached a lever 48, provided with a spring 49 and a latch 50, the latter in a position to engage a shoulder 51 on the cross head 30, carrying cross pin 29. referably the end of the carrier is slotted for the reception of lever 48 and the latter provided with a guiding extension 52 working in said slot to prevent displacement of the lever. The arrangement is such that when the mold blade sections are adjusted to aline their casting faces, as when the main section 24 contacts with carrier block 37 and the latter engages the front stop 27, latch 50 will be in position to pass shoulder 51, and will be automatically actuated by its spring to so pass the engaging shoulder, thus locking the carrier and cut-off section to cross-head 30.

To insure the engagement of latch 50 with its shoulder 51 when the mold sections are in their extreme forward or ejecting position the opening 28 in the lower or main section 24 is made slightly greater than the thickness of the cross-pin 29 so that when the latter engages the front wall of said opening, to clamp the carrier gage block 37 against front stop 27, shoulder 51 will slightly pass the point of latch 50 and the latter will automatically enter behind said shoulder. If now cross head 30 is retracted to dimension the mold, its movement will be communicated through latch 50 to carrier 32 for the cut-01f section and through gage blocks 37 to the main section, until arrested by the engagement of the main section with the limiting or dimensioning member WVhen, however, a low quad or space is desired it is only necessary to withdraw latch 50 and advance the cut-off section into the mold cavity, leaving the lower or main section 24 under the direct control of cross pin 29. These operations can be performed either separately or concurrently, that is to say, separate means can be supplied for releasing the latch and for advancing the cutoff section; but the preferred plan is one in which a single actuating member 54 is arranged to engage lever 48 in a direction to first withdraw the latch and then, by a continuation of the motion, advance the cut ofi section, to which end a stop 55 is arranged in the path of extension 52 to arrest lever 48. Actuating member 54 lies nor mally outside the path traversed by lever 48 when the sections are locked for simultaneous adjustment, as when full body type are called for, and any suitable control mechanism, of which examples may be found in Patent No. 828,450, of August 14, 1906, and application Serial No. 506,550, filed July 8, 1909, may be employed to produce or govern said actuating member and to maintain the cut-off section projected during the casting of the low quad or space. In the examples referred to actuating member 5% is advanced, to withdraw the latch and project the cut-off section into the mold cavity just before the cross-pin retracts to dimension the mold by seating the main section upon dimensioning member 53.

To prevent the entrance of foreign sub stance and to supplement the action of the top bearing, cover plate sections 56, 57, are secured to the rear abutment, the one engaging the upper edge of the main section and the other the carrier 82 above their bearings upon off-set 34.
