RULE-PUNCHING M ECHANjfSM.

Application filed May 2, 1923, Serial our invention relates to devices for punching' or notching type-bars, slugs and rules to receive inserted column-rules of the so-called lino-tablar form, extending'transversely of the punched typehars and rules. It is the particular object 015 our invention to" provide,

a punchfor producing small triangular or wedge-shaped notches opening to the printing face of a type-metal rule or rule-slug, in which the punch or perforating member is'so' guided and supported as' not to be liavble'to deflection, bending or breakage, by continued use for the purpose forwhich it is intended. A further object'of our invention is to provide a rulenotching punch mechanism wherein the depth of the notches is gaged solely with re spect to the printing faces of the rules or slugs, so that variations in the height'ot' the punched members willnot affect the relative height of the inserted column-rules, and the printing faces of the latter will be always perfectly alined with other printing-faces of a form. A further object of our invention is to provide a simple and convenient mechanism adapted. to securely hold an assemblage or gang of punch-units, together with a plurality. of spacing plates and gages, in positive and definitely alined relation to each other, whereby any desired number ofnotche's may hem-ado simultaneously in a type-metalv rule, type-bar or slug, the notches being accurately located longitudinally ot the rule or slug and also with referencetothe printing-face thereof, and the punching operation repeated to produce any number of parts notched in exact duplication of each other. Our invention further comprises means by which a plurality of punch-units may be assembled and held in a definitelymeasured relation toeachi other, determined by the thickness of spacing members iuterspaced with the punch-units, the spacing members beingxof standardized thickness and varying only in multiples of a fixed unit-thickness. More particular objects of our inventionwill appear hereinafter.

In carrying out our invention according to the illustrated embodiment thereof, we provide a plurality of punchese'achof which is formed from a flat steel, bar 20 of rectangular sectional form, the thickness of the bar being slightly more than the greatestwidth oi the notchesto be f'orme'ch The lower rear portion oithe bar is recessed at each side to leave a thin flat blade 21 of which the front edge merges into the triangular or wedgeshaped part 22, the latter:eoinprising 'the punch proper or perforating. member, and the widest portion thereof being: alined' with the front-edge of the bar 20.; as-shownin'Fig. The blade 211 projects'ifora short distance below thelower endof the triangular part 22; and the front edge 2310f fsaid projecting portion forms a gage for limiting-the distance to whicha rule or slug-may be inserted beneath the-cutting edges at the lower end of the part 22; Near the'upper end of the bar -20 a notch'fl l is formed in the rear side there of for receiving the actuating member. At about the level of the lower side'of the notch 24* there is a transversely extending's'top-pin 25which projects slightiyat eaehsi'deof the bar. Theguide or housing-for thepuneh is formed by two symmetrical parts- 26 and'27 which are secured'together by aplurality of screws 28, said screws entering. threaded openingsin the part" 26, and=the flat heads of thescrews beingxeountersunk in the part 27.

The adjacent sides of the parts 26 and 27 are channeled to form a passage for receiving the punch-bar slidably between them, the width of the channel bein greater at the upper portion than at the lbwer portion, so that both the main upper portion of the bar and the thin web or blade 21 at the lower portion are guided and supported laterally as shown in Fig. 9. At the front side of the housing, near the lower end thereof, is a rectangular transverse recess 29 which intersects the front portion of the channel for the punch-bar, so that the-rear end of said recess 29 is slightly behind the gage-surface 23 at the front edge of the bladeQl, as best indicated in Fig. 7'. The portion of the housing beneath said recess 29 forms the die-block which supports the work and into which the lower end of the part 22 passes at the completion of a punching operation. The opening for said part 22 fits the same closely for a short distance below the recess 29, and a larger clearance-opening 30 extends therefrom to the bottom of the housing, as best shown in Fig. 8. The punch-bar may be withdrawn from or inserted into the upper end of the housing, and the stop-pin 25 limits the depth to which the bar may enter the housing. Below the recess 29 the front face 31 of the housing is inclined forwardly, and a corresponding rearwardly inclined face 32 is formed atthe back of the housing, said inclined faces 31 and 32 being accurately positioned with respect to the punch, so that when said faces are'engaged by the hereinafter described clamping means a series of the punch-units may be properly alined with each other.

Referring now to the holding and actuating means for the described punch-units, in the preferred and illustrated embodiment thereof we provide an integral base-member 33 having perforate foot-portions 34 adapted to be secured by bolts orscrews to a suitable support. The upper side of said base-member is a plane-surfaced table, except at the rear edge where there is an upwardly projecting flange or gib 35, the front face of which is undercut so as to fit against the rear inclined faces 32 of the punch-housings when the lower ends of the latter rest upon the table. Said flange or gib 35 thus forms a fixed clamp-member which serves to accurately aline any. number of the punch-units. A; parallel, coacting, movable clamp-member is formed by a bar 36 which is mounted pivotally in a recess or trough 37 extending longitudinally of the base intermediate its front and rear sides. The clamp-bar 36 extends above the table suificiently to engage the inclined faces 31 at the front sides of the punchhousings, the rear side of the bar being undercut to fit against said faces. In the lower portion of the trough 37 is a rod 38 of which the ends are held in the end-portions of the base, and a tubular sleeve 39 is disposed upon the rod intermediate said end-portions. Lugs 40 on the lower portion of the clampbar 36 fit pivotally about said sleeve 39, and

the central one of said lugs 40 is cut away at the rear side so that a screw ll, which extends through the rear side of the trough, may en gage the sleeve as shown in Fig. 6. A plurality of small coil springs 42 are disposed in pockets formed in the rear side of the clampbar, said springs engaging the rear side of the trough and tending to swing the bar forwardly away from the punch-housings. Clamp-screws 43 extend through the base from the front. side thereof, said screws having winged heads, as shown, and the rear ends thereof being engageable with the clamp-bar to press the samefirmly against the faces 31 of the punch-housings. As said clamp-screws engage the'bar 36 at points intermediate the punch-housings and the fulcrum-rod 38, there is a tendency to bend said rod rearwardly, and the screw 11 is used to prevent such bending of the rod.

Between the gib 35 and clamp-bar 36 the table is slotted from end to end, the slut being parallel with the clamping members. In said slot at the ends of the base are fitted hearing blocks 4%, and a similar block 45 is disposed at the middle of the slot, said blocks being fixedly held in place by means of setscrews 46 extending through the base from the rear side, as shown. Said bearing-blocks support revolubly the ends and central portion, respectively, of a shaft 4:7, of which one end is extended beyond the base and carries a crank 48. The portions of said shaft intermediate the center-block 45 and end-blocks 4A are threaded to form right-hand and lefthand leadscrews, on which are mounted the vice-jaws -19. The lower portions of the vice jaws fit slidably in the slot of the table, and the upper portions of said jaws extend above the surface of the table, as shown in Fig. 11. By rotation of the crank 48 the jaws are moved toward or away from each other, according to the direction of rotation.

A rocking-shaft 50 extends longitudinally through th rear portion of the lame, beneath and parallel with the gib 35, and upon the projecting end-portions of said shaft are fixedly secured the arms 51 and 52 which cxtend upwardly therefrom. Said arms have rcarwardly projecting lugs 53 intermediate their upper and lower ends, and between said lugs the cross-rod 54 is fixedly secured. An arm 55 is formed integrally with the arm 59., and extends forwardly from the rockingshaft,alongside the end of the base and beneath the projecting end of the vice-screwshaft a7. a head 56 in which a latch-pin .37 is slidably held. A small coil spring, indicated by dotted lines in Fig. 1, is arranged around the latch-pin within the head 56, said spring en- At the front end of the arm 55 is gagin a shoulder on the pin and pressing the sameton' -ard the base. An opening is formed in the end of the base for receiving the inher end of the latch-pin, and when the same is entered in said opening it holds in fixed normal position the rocking frame comprising the arms 51, 52 and 55, the shaft 50. and the cross-rod 54. The punch-actuating lever is mounted. pivotally between the upper ends of the arms 51 and 52, said lever coi'nprising a bar 58 having an integrai forwardly extending lip 59, termii'lating in a rounded head 60 adapted to lit within the notches Qel of the punch-bars, and a handle 61 secured upon the central portion of said bar and extending upwardly therefrom. Screws 62 extend through the frame-arms 51 and 52 into the ends of the bar 58 to form the pivotal conn'ection of said members. Near the ends of the bar 58 are rearwardly projecting fingers 63, and from said fingers the tension springs 64 extend downwardly to connect with eyebolts 65 on the rear side of the base. At one end of the bar 58 is an upwardly extending lug 66 having a threaded opening therein to receive an adjusting-screw 67, the rear end of said screw being adapted to engage a stop lug 68 on the arm 51, whereby to limit the lifting movement of the actuatingdever, as effected by the springs 64. By grasping the head of the latch-pin 57 and pulling said pin outwardly to disengage the same from the base, the rocking frame is released and may then be tilted backwardly to a position such as shown by dotted lines in Fig. 2. The punch-actuating lever is thereby disengaged from the punch-bars, and the space above the clan'iping devices is cleared to provide easy access to the parts held thereby.

In the table or top of the base, in front of the trough 37, there is a rectangular groove which extends at one end through a lug 690n the end of the base. In said groove is slidably disposed a bar 70, the same being retained in the groove by a thin cover-plate 71. At the front side of the lug 69 is a knurledhead set-screw 72 which may be tightened against the bar to hold the same in longitudinally adjusted positions. To the upper side of the bar, adjoining said lug69, there is secured a finger plate 73 which extends rearwardly and has a vertical lug 7 4 integral therewith. Said 111g 74 forms an end-gage for positioning long rules or the like with respect to punches held by the vicejaws and clamped between the gib 35 and clamp-bar 36. For short rules, and for typeslu'gs and the like, the longitudinal position with respect to the punches is gaged bymeans of plates 75 which are clamped in the holding devices in the same manner as the punch housings. One of said gage-plates 75 is ind icat'ed in Fig. l. adjoining each of the viceiaws. The thickness of thepunch-housings is preferably a unit of printers measure,

usu'al-lyone pica, so that it" a series of the housings are assembled in the holding means alongside each other, the punches will be positioned tor notching rules and the like at points spaced apart one pica. When a series of the punch-housings are so assembled, if it should be desired to omit the notches at one or more points on the rule, the punches may be removed from the respective housings,

and the remaining punches then operated without changing the assembly of the housin gs. To avoid the use of. an excessive number of the punch-housings for filling out the desired longitudinal spacing of the punches to be operated, we also provide a plurality of spacing-plates 76, which are of the same outline form as the lower portions of the punchhousings, so as to fit between the clamping i'i'iembers and 36, but. of which the thickness is varied so that by suitable combinations of the plates any desired spacing of the punches may be attained. Preferably, the thickness of the spacing-plates is varied in multiples of the point unit of printers measure, some of the plates being, for example, two-points thick, others six-point, and others twelvepoint or one pica. The ordinary spacing-plates 76 are recessed at their front edges to the same depth as the recesses 29 of the punch-housings, so that when a rule or rule-slug with athin hair-line printingface is inserted for punching, said printingi'ace will not be marred or deformed by engaging the ends of said recesses, but will engage only the gage-races 23 of the punchblades 21. As the portions of the printingfaces so engaged with the faces 23 are cut away by the operation of the punch s, it will be apparent that the remaining portions oi? the pi-intiin daces of the punched rules will show no deio nation, even it the rules should be pushed against the gage-faces 23 with an necessary force. 7

Referring to Figs. 13 and 14, there is shown a special form of the spacing-plates,

761, whereinthe recesses are formed with a shoulder or offset 77, beneath which a thin slot 7 Sextends back to at least the depth of the recesses 290i the punch-housings. When punching thin rules A, one of said special plates 76]. is preferably disposed alongside each of the punch-units, so that, when a rule is inserted for punching, the same will extend into the slot 78 as shown in Fig. 14. The plates 761, when so employed, serve as strippers to prevent lifting of the rule during the withdrawal of the punches therefrom, which might deform the notches or the printing-face of the rule. The special plates 761 are also employed when punching a type-bar or slug B with a rule-face, such as indicated in Fig. 13. For this purpose the shoulder 77 is so located as to engage the shoulder of the slug B when the same is inserted to the proper depth beneath the punches. It should be noted that the slug B is of the character formed by linotype and similar type-bar casting machines, wherein the shoulder of the slug is always at a uniform distance from the printing-face, although the over-all dimension of the slug may not be exactly typc high. It will thus be seen that when the punched notches are gaged from the shoulder of the slug the notches will be located in the same relation to'the printing-face as if gaged directly from said face, and without liability of the printing face being marred by the gage.

In the preparation of ruled printingtorms it is often desirable to employ typeslugs C of the character indicated in Figs. 15 and 16, having at one or more places intermediate the type-faces c lugs 79 which may be punched or notched to receive linotabla r colunmrules of which the base-portions will rest upon the shoulders of the slugs. For use with type-slugs of this kind, we provide special gage and spacing-plates 702, one ofwhich is shown in Fig. 12, in connection with one of the punch-units. Said plate 762 has in the front side thereof a rectangular recess similar to the recess 29 of the punch-housing, but with the end 81 of said recess slightly in front of the end of the recess 29, which is indicated by a dotted line in said Fig. 12. l/Vhen the plates 762 are assembled with the punch-units in the clamping mechanism, said end-faces 81 are alined with the gage-faces 23 of the punches. When the slug C is inserted for punching, the type-' faces a engage the surfaces 81,, and the lugs 79 are thus positioned with respect to the punches as shown in Fig. 7, so that the .notches punched in said lugs are properly positioned for holding the inserted rules with their printing faces at the same level as the type-faces.

From the foregoing the general operation of the mechanism will be apparent. \Vhen changes are to be made in the arrangement of the punch-units, the latch-pin 57 is pulled out to release the rocking frame which carries the punch-actuating lever, and said frame is tilted backward to disengage the lever from the punches. The crank 48 is then turned to move the vise-jaws 4-9 apart, and the clamp-screws 4.3 are turned to relieve the pressure of the clamp-bar 36 against the punch-housings and spacing-plates. Said members can then be removed or additional members inserted in the holding mechanism in the proper arrangement according to the workto be done, after whichthe crank 48 is turned to press the vise-jaws lightly against the ends of the assemblage, then the clampscrews 43 turned to press the parts lightly against the gib 35 to properly aline them, and finally both the vise or side-clamping means and the bar 36 or end-clamping means tightened up to securely hold the parts in alined and adjusted relation. For short rules, and for type-bars and sings, the longitudinal relation thereof to the punches is gaged by means of the plates 75, which are arranged at the proper distance from the punches. For rules of which the length is greater than can be accommodated by one of the plates held between the visc-jaws, the lug 7a is employed as an end'gage, the bar 70 being adjusted to hold the lug in the desired position, and the bar being secured in adjustment by the screw 72. After clamping the punch'units, spacing-plates and gages in the desired positions, the rocking frame is swung forward to engage the head 60 of the punch-actuating lever in the notches 2a of the punch-bars, said frame being retained in operating position by the latchpin 57. The rules or type-bars to be punched are then inserted beneath the punches, being pushed lightly rearward against the gaget'aces,and the lever-handle 61 then pulled forwardly to force the punches down through the work. The chips or punchings pass down through the clearance-openings 30 into a longitudinal groove in the table, from which they may be removed from time to time, as necessary.

It will be obvious that by the formation of the perforating members 22 integrally with the blades 21, and the guiding and supporting of said blades at their sides and rearward eugc, the members are effectually prevented from being deflected, bent or broken by normal and proper usage of the mechanism. It will also be apparent that by the use of the spacing-plates 76 of standardized thickness, and the use of the vise-jaws to press the assemblage firmly together longitudinally of the alining clamp members 35 and 36, the punches may be easily located in exact and measured relation to each other, and retained in such relation during operation upon any number of parts.
