RULING-MACI-IINE.
Application filed March 3, 1913.
To all whom it may concern:
Be it known that I, Harmon E. LIND- BLADH, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Ruling-Machine, of which the following is a specification.
My invention relates to ruling machines, and especially concerns the type in which means are provided for individually controlling the action of the ruling devices. Its purpose is generally to increase the precision of the machine and the ease with which it may be operated.
In the accompanying drawings, in which like characters designate similar parts throughout, Figure 1 is a broken top plan view of one embodiment of the invention; Fig. 2 is a side elevation thereof; Fig. 3 is an enlarged central vertical longitudinal section through a portion of the machine; Fig. 4f is an enlarged detail in front elevation of a part of the gate; Fig. 5 shows an enlarged section on the line AA of Fig. 1; Fig. 6 is a top plan view of Fig. 5; Fig. 7 illustrates in plan one of the carrier-sleeves for the controlling levers; Fig. 8 is a perspective view of a clip for securing said levers to one another; Fig. 9 shows in side elevation the spring for cushioning the penbeam and the adjusting means for said spring; Fig. 10 is a detail of the universal support of the pen-beam, and Fig. 11 illustrates a form which may be ruled by a single operation of my improved machine.
Journaled at their opposite extremities in a suitable supporting frame 10 are drums, one appearing at 11 in Fig. 2 of the drawings, over which operates a belt or feeding member 12. This belt passes above a guideroll 13 rotatable in the frame, and across atable l l havin its upper face lying in a substantially horizontal plane beneath the ruling devices, which are to be later described. Above the belt-drum 11 is journaled in the frame a feed-drum 15, between which and the belt the work or sheets to be operated upon are introduced from a delivery-shelf 16. Power is applied to the feeding members through a main driving shaft 17 carrying a pulley 18 which may be rotated at the desired speed by a belt from a convenient source of power. Fastupon the shaft 17 is a pinion 19 meshing with a gear 20 fixed upon the spindle of the feed- Specification of Letters Patent.

ing drum 15. This gear cooperates in turn with a gear 21 of the same diameter upon the spindle of the belt-drum 11, thus causing the advance of the belt and the pe riphery of the feeding drum at the same speed. To allow the driving power to be thrown off the machine, the connection between the' shaft 17 and pinion 19 is through a clutch 22 which may be shifted by a rod extending across the machine and having a handle in a convenient position to be grasped by the operator. As it may be desirable in adjusting the machine to temporarily operate itby hand, a crank 23 is secured to the spindle of the drum 15 adjacent to the handle of the clutch-rod.
Supported upon the top of the frame is a base-plate 2%, preferably in the form of an open rectangle, from the longitudinally 6X- tending side members of which rise opposite standards 25, 25, in which a transverse bar or beam 26 is supported near the rear of the table 14:. Upon this bar are mounted pens or ruling devices 27 of any suitable construction they being in the present instance of flexible sheet metal, each having a shank 28 which is grasped by a clamp 29 secured to the beam through set-screws 30. The points of this series of pens cooperate with the belt 12 over the table 14. They are sup plied with ink of the desired color by any convenient device (not illustrated).
At the opposite ends of the pen carrier beam are spindles 32 and 83 carried by frames 34:, 3% supported upon the standards 25. To enable the pen-beam to be adjusted vertically with respect to the work passing beneath it upon the belt, the frames are slotted and through these slots and through openings in the standards project bolts 36.
These bolts when tightened serve to fix the frames in the desired position upon the standards. To permit horizontal adjustment of the beam laterally of the machine, the spindle 32 is threaded through its frame 34:, and has a hand-wheel 37 by which it may be turned. To lock the threaded spindle in position, a handled nut 38 operating upon the spindle may be forced into contact with the frame. The opposite spindle 33 is mounted to slide with some lateral play through an opening in a swiveled turret and to rotate therein. The spindle 32 is connected by swivel 40 to a block 39, preferably movable on a pair of vertical trunnions 140 path of the screw, and the bar is thereby held in its upwardly tilted position until it is again released by throwing back the latch.
In this machine I furnish means for inde pendently controlling the engagement with the work of each pen of the series of this beam 26 and for simultaneously moving the entire series as well. Extending across the machine at the rear of the pen-beam 26 is a shaft or like support 46 fixed in standards 417, 47 carried by the base-plate 24. Upon this shaft, arranged in a single series, are fulcrumed lifting or controlling levers l-S each having a nearly horizontal arm l9 projecting beneath the beam 26 to a point near the forward extremities of the pens. The opposite arm of each lever is upwardly inclined, and has a substantially horizontal extremity 50 for contact with the actuating members to be hereinafter described. There may be carried upon the shaft 46 controlling levers for as many of the pens as may be at any time employed, those which it is not desired to actively use being moved to one side out of the path of the sheets traveling through the machine, as is shown in Fig. 1.
Since it is often necessary to operate closely adjacent pens, and as these pens are individually very narrow, the controlling levers must be thin, and consequently themselves present little bearing surface to the shaft 4E6. Therefore, if they were supported directly upon the shaft, they would tend to rock laterally and become disengaged from the pens. To overcome this difficulty, I preferably mount the levers in groups upon carriers, each group being held against angular lateral movement by such carrier. In the present instance, the levers are illustrated asbeing carried in pairs upon sleeves 51,-the interior of which fit theshaft 46 to slide thereon, while upon the exterior the levers oscillate, con tacting with one another at their adjacent faces. At one end of the sleeve is an integral flange 52 against which one of the levers rests, and at the opposite end is a removable flange 53 retaining the associated lever, this flange being secured in place by screws 54: engaging the end of the sleeve. The outer sides of each pair of the levers are provided with annular recesses surrounding the openings through which the sleeve passes, these recesses being of such size as to receive the flanges 52 and 53, their outer surfaces being practically flush with the faces of the levers. To prevent the rotation of the sleeves 51 upon the shaft 926, the latter has a spline 112 entering grooves along the interior of the sleeves, which are still freely movable across the machine. By this carrier arrangement I amable to place the controlling levers as closely to one another as though they were mounted directly upon the shaft, and yet provide them with positive support against lateral displacement. If it is desired that certain of the controlling levers shall move together as a nnit,for example the two levers mounted upon one of the sleeves,
a clip 55 may be placed over the ends of the portions 50. structed of resilient sheet metal, made in the form of a rectangle with an opening at one side and so flared at 56 that it may be readily placed in engagementwith the levers. When the pair of levers is thus connected, they may be moved togetherunder the influence of common actuating means and will then lift adjacent pens together. Obviously the clips may he made of different sizes to embrace (lill'erei'it groups of lovers.
To hold the levers which. are in use in correct relation to the pens with which they are to cooperate, he shaft i6 is provided with a series of generally V shaped rooves 57 (Fig. 6) extendin about a portion of the circumference of the shaft and respectively alined with the pens. Each controlling lever has a projection, preferably furnished by a stud 58 carried by a lever 59 fulcrumed at 60 upon the controlling lever. A spring 61, interposed between the end of the lever 59 opposite the stud and the controlling lever, forces the stud through an opening in the controlling lever and through a slot 62 in the sleeve 51. The pointed end of the stud is adapted to enter any one of the grooves in the shaft, according to the place to which the sleeve carrying the lever is moved. When thus positioned it is forced into the groove by its spring, furnishing a lat-ch readily releasableby pressure of the finger of the operator upon the outer end of the lever 59. lVhen in engagement with a groove, this latch holds the controlling lever and their sleeve against displacement along the shaft elfi, yet lea es said lever free to oscillate about the shaft. In tl is movement of oscillation the forward point of the controllin lever rests a ainst the underside of the corresponding pen, and when its opposite end is depressed raises the working point of the pen from the belt, this pen-movement being permitted by the flexibility of its shank.
To maintain each controlling lever normally in contact with its pen, there is secured to said lever a leaf-spring63 which extends over a rod or bar 64 supported near the top of the standards l7. However the This clip is preferably conlevers may be situated their springs, which are bodily movable with them, will find engagement with this rod and thus always be under tension, irrespective of lateral adjustment.
Fixed to the rod 64 near each extremity within the standards 17 are arms 66 held in place by set-screws 67. At the outer ends of these arms are openings to receive and sup port a rod or bar 68 engaged by set-screws 69 threaded through the arms. This rod 68 extends over and in close proximity to all the controlling levers and serves as a stop common to them. When the position of the rod is adjusted vertically by loosening the setscrews 67 and swinging the arms about the rod 64, the distance which the pens are allowed to move toward the work by the controlling levers is simultaneously varied for the entire series. This may be useful in connection with operations upon sheets which present irregular or wavy surfaces, since in this manner the clearance of the released pens from the sheets may be assured. To separately aline the controlling levers and to properly position their forward extremities with respect to the pens, each lever carries upon its upper edge an adjustable contact member or block 70 lying below the stop-rod 68. The upper face of the block is shown as inclined, so that upon its move ment longitudinally of the lever the vertical position of the point of contact between the block and stop-rod will be altered. To shift the block an adjusting member is provided, consisting of a screw 7 2 threaded through a lug 73 rising from the lever and having a non-threaded end-portion freely rotatable in the block. This end is retained in engagement with the block by a head 74: at one side and a collar 7 5 at the other. At the 'forward end of the screw is a thumb-piece by which it may be readily turned by the operator, and any one of the controlling levers thus quickly adjusted with respect to its pen without the use of tools. The screw 72 is held in its adjusted position by lock-nut 76 contacting with the face of the lug 73.
In some work, instead of lifting the pens individually, it may be desired to operate them all simultaneously. In such case it is convenient to rock the beam 26 as a whole upon its swivel 40 and spindle 33. To effect this movement the arm 41 may have a contact surface 77 (Fig. 2), which is engaged by a special controlling lever 78 fulcrumed near one extremity of the shaft 46. A spiral spring 79 (Fig. 3), extending between the baseplate and an arm 80 projecting from the beam near the spindle 33, draws the end of the screw 42 against a portion of the bracket 45. To cushion the downward movement of the relatively heavy beam, the end of the arm 80 contacts with a spring 81, shown as occupying an inclined position and projecting from a block or carriage 82 mounted to slide in a way 83. This carriage has a slot through which extends a screw 8 1 to secure it in position, this determining the cushioning effect of the inclined spring. Though differently proportioned to adapt it to the service it is to perform, the lever 78 is in no essential particular different from the levers 48, exceptthat as the former may be of ample width at its fulcrum point on the shaft 4L6, it is unnecessary to mount it upon a sleeve or carrier.
Sometimes, and especially when a form is to be ruled in which a second group of lines begin and end at corresponding points or upon which certain lines are very closely placed, much labor is saved in setting the machine for its work by having a second beam or pen-carrier 85 which may be oscillated as a whole to simultaneously lift its pens. This beam is mounted in advance of the beam 26 on standards 86 fixed to the base-plate 24 in a manner exactly similar to the arrangement of said beam 26. A controlling lever 87 fulcrumed beside the lever 78 upon the shaft 46 directly operates the beam 85. To cause the ends of the levers 78 and 87 to move more readily over the surfaces of the beam-arms, they may be provided at their contact ends with anti-friction rolls 88.
Journaled to oscillate in standards 89, 89 carried by the base-plate is a vertical series of shafts or supports 90, upon each of which may be variably fixed by set-screws 91 a series of actuating arms 92. These arms on the various shafts are of different lengths, but those on the same shaft are of the same length, having horizontal portions 93 and vertical portions 94 which are respectively parallel with one another upon succeeding shafts. All these vertical portions extend over the ends 50 of the controlling levers and coo ierate with slots 95 lying along the upper sides of the ends of the levers, these slots retaining the engaging points of the arms against disengagement. The portions 9 2 of the levers for each shaft occupy different vertical planes with respect to the other groups and thus clear them, so that all the arms of the various groups may be freely adjusted upon their shafts across the machine without interference with the arms of the associated groups.
To impart to each shaft 90, and consequently to each of its groups of arms 92 and corresponding groups of controlling levers and pens, the pen-controlling movement, there is fixed to each shaft 90 a driving arm 96. This arm is fixed by a set-screw 97 to a rod 98 forming one member of a rectangular fulcrum frame, the other members of which consist of the parallel shaft 90 and a pair of arms 99, 99 secured outside the arms 92.
Each driving arm 96 has at its outer or rear extremity an anti-friction roll 100 contacting with a'cam-surface 101 upon a wheel 102, the number of wheels corresponding to the number of different pen-movements. These cam-wheels are fast upon a shaft 103 journaled in standards 10%, 104E rising from the base-plate, and are rotated by a pinion 105 meshing with a gear 106 turning upon a stud 107 and also engaging a gear 108 on the spindle of the belt-drum 11. The stud is adjustable in a sector-shaped slot concentric with the shaft of the gear 108 and situated in an arm 109 depending from the underside of the base-plate. The pinion 105 is made readily removable so that by placing upon the shaft 103 pinions of various diameters and correspondingly adjusting the gear 100,
suitable limits.
the rate of travel of the cams with respect to the feeding members may be varied within The cam-surfaces may be furnished by plates 110, situated in peripheral grooves in the wheels 102 and secured by screws 111 engaging circumferential series of holes about the wheels. By altering the extent and location of the plates 11.0, the contour of each cam-surface may be varied to properly timethe operation of its group of actuating arms, controlling levers and pens. To permit a further adjustment of the throw of the actuating arms and therefore of the lift of the pens, each driving arm 96 is made in sections, there being a substantially vertical portion 113 carried by a short angle-arm which is fixed ,to its shaft, and a generally horizontal portion 114. These two sections are articulated at 115, the lastnamed having a downward extension at the extremity of which is a slotted sector 116, through which a bolt 117 is threaded into the vertical portion 113. One very marked utility of this adjustment is that if after having correctly arranged the cams to give the desired time of lift and release to the pens it is found that they do not properly discharge the ink for the particular grade of stock operated upon, the angular position of the portion 114- of the driving arm may be changed. This, without varying the point of application and removal of the pens with respect to the work, will alter the distance through which they move before they contact with the sheet, and therefore the force with which they strike, and thus cause the ink to be initially discharged with greater or less freedom. It will be seen that each fulcrumframe with its actuating arms 92 and driving arms 96 furnish a multiple-armed lever connecting a driving cam with one of the groups of controlling levers, and that the driving arm and actuating arms are each adjustable over the full width of the machine without interference with the opposite arms of the same lever. As the springs 03 force the arms 50 of the controlling levers against the arms 92 of the actuating levers, they also force the rolls 100 of the driving arms into cooperation with the cam-surfaces. To limit the movement of the driving arms after they have been released by the cams, I have provided a stop-bar 118 extending at the rear of the portions 113 of the levers, and adjustably mount its ends in slots extending horizontally along brackets 119 carried by the standards 89. To cushion the blow of the driving arms upon the stop-bar, thus reducing the shock and noise, sleeves 120 of resilient material, such as rubber, surround the bar. A sleeve for each driving arm is shown, preferably held in place by its own resiliency, and with these sleeves contact lugs 71 projecting from the portion 113 beyond the upper pivoted section.
Mounted outside the arms 99 directly on two of the shafts 90, since it is unnecessary to adjust them laterally of the machine, are actuating levers 121 and 122 for the controlling levers 78, 87 and their beams 26, 85, respectively. In the case of these levers the actuating and driving arms may be made integral. The latter arm, however, is prefer- L ably formed in adjustable sections similarly to the levers for actuating the individual pens. The transmission of movement from a driving cam to a distant pen-beam, as 85, through two cooperating levers, as 122, 87, instead of through gearing, as is usual in ruling machines, avoids irregularities in the striking of the pens upon the work which would be introduced by the backlash of the gearin The machine is equipped with a gate 123, which positions each sheet upon the feedbelt and automatically releases it for presentation to the pens. This gate consists of a shaft or support 12 1 mounted in bearings 125, 125 formed in the cam-shaft standards 104, and has fixed at intervals along it holders 126. In these holders are upwardly extending sockets or openings to receive teeth 127 each secured by set-screws 128. The gates are of considerable length and there fore tend to spring or bend in use, distorting the horizontal line at which the teeth contact with the feed belt, but with my improved gate each tooth may be independently adjusted by loosening its set-screws, shifting the tooth in its opening, and again turning the screws into engagement with the'tooth, thus producing a perfect alinement of the contact portion of the gate. From the shaft of the gate an arm 129 projects into cooperation with a cam 130 carried by the shaft 103. An anti-friction roll 131 upon the gate-arm is shown as drawn into contact with the cam by a spiral spring 132, extendingbetween a downwardly projecting arm 133 and the frame. The working contour of the cam 130 is such that the gate is for a brief period held in the path of an approaching sheet to position it upon the belt, and is then released at the correct time with respect to the cam wheels 102 to free said sheet and allow it to travel with the belt beneath the pens in accord with their lift.
The sheets to be operated upon may be so cut that their adjacent edges are not truly at right angles, and to present the sheets properly it may be necessary to adjust the angle of the gate with relation to the feed belt to cause the ruled lines to become parallel with the edges of the sheets which extend in the direction of said lines. To effect this, the base-plate 24 is movable upon the top of the frame, being pivoted at one corner upon a screw 134, and clamped in place by a screw 135 passing through a slot 136 (Fig. 1) in. the base-plate into engagement with the frame. lVhen it is desired to vary the position of the gate to correspond to the previously mentioned irregularity of the sheets, the screws 134 and 135 are loosened and the base-plate swung about the former through an angle corresponding to the departure of the edges of the sheet from a right angle, the slot 136 permitting this movement. Then both screws are again turned down to fix the plate in position. In thus positioning the gate both pen-beams and all the controlling elements are shifted to the same extent, so that the lift of the pens is not altered. I also prefer to provide for the independent adjustment of all the standards upon the base-plate, and to this end each of the standards 47, 89 and 104 has in its foot slots 137 lying longitudinally of the frame, through which slots pass screws 138 into threaded openings in the base-plate. The beam-standards 25 move in ways 139 in which they are secured by screws 141. By this means the position of the pen-bars, controlling and actuating levers, and cams and gate may be very precisely fixed with respect to one another and to the feed-belt.
To prepare this ruling machine to produce, for example, the form illustrated in Fig. 11,a controlling lever 48 is adjusted beneath each pen which is to be separately raised from the work. This is accomplished by sliding the sleeve 51 carrying the levers 49 along the shaft 46, the spring latch of the controlling lever being raised, and then re leasing this latch to allow the stud 58 to engage in the shaft a groove 57 which is alined with the pen. When all the pens of the beam 26 are to be lifted at the same time, the lever 7 8 is brought into action; and for the production of closely placed lines or for other exigencies which the operator may encounter in particular cases, the beam 85 and its lever 87 are employed. For each group of lines beginning and terminating at the same point, other than the two groups corresponding to the movements of the pens of beams 26 and 85 as a whole, a cam-wheel102, shaft 90 and driving arm 96 are utilized,
cessively advanced between the belt and the feed-drum. Upon reaching the gate they contact with its teeth and are squared on the belt by them, and then released by the action of the gate-cam at the proper time for pres entation to the pens. This time of release bears a definite relation to the period of operation of the pen and beam controlling cams, so that the beginning of the ruled lines will be at the proper distancefrom the forward edge of the sheet. As the sheets advance over the table beneath the pens those not lifted by the controlling levers produde their lines; and as the travel of the sheets continues the passing of the cam-surfaces 101 from beneath certain of the driving arms drop their pens, which also produce other lines. Thus the ruling of all of the lines running in this direction across the sheet is completed at a single operation, this continuing for each sheet delivered by the gate, the different lengths of lines being automatically controlled throughout. When another form is to be ruled, it is a comparatively simple matter to vary the pens, the actuating and controlling levers and their operating cams to meet the new conditions.
