MACHINE FOR PRINTING WADS ON-BOTH SIDE S.
SPECIFICATION forming part of Letters Patent No. 524,610, dated August 14, 1894. Application filed April 30, 1894. Serial No. 509,480. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES R. RICHARDS, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Printing Wads on Both Sides; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to the class of machines illustrated and described in Letters Patent No. 506,37 4, for a machine for printing wads, granted to me October 10, 1893, and has for its object to perfect certain of the details of construction of said machine and to so improve the machine as a whole that it will print both sides of the wad simultaneously, the requirements being, as stated in my former patent, that the machine shall work rapidly, shall print the wads clearly, shall manipulate them in such a manner that no blurring shall take place and that the machine moreover shall be capable of receiving the finest adjustments and at the same time be simple in construction and not liable to get out of repair.
With these ends in view I have devised the novel machine of which the following description in connection with the accompanying drawings is a specification, numbers being used to designate the several parts.
Figure 1 is a side elevation of the machine complete; Fig. 2 aside elevation on an enlarged scale the point of view being from the side opposite to that in Fig. 1; Fig. 3 a section on the line w in Fig. 4 theinking mechanism being removed and the operative parts of the machine being in end elevation as seen from the left in Fig. 2; Fig. 3 a detail view illustrating in side elevation and in inverted plan the lower end of the expelling rod; Fig. t a sectional view on the line .2 z in Figs. 1, 2 and 5; Fig. 5 a vertical section on the line yy in Figs. 3 and 4; Fig. 6 an inverted plan view corresponding with Fig. 4 portions of the machine beingin section on theline m min Figs. 1, 2 and 5; Fig. 7 asection on .the line 83 in Fig. 8; Fig. 8 a section on an enlarged scale on the line i; v in Figs. 7 and 9; Fig. 9 a detail plan view corresponding with Fig. 8; Fig. 9 a detail sectional view on the line 0 0 in Fig. 9; Fig. 9 a detail sectional view on an enlarged scale on the line u u in Fig. 9,but showing the dial as having advanced to an intermediate position, a wad in one of the holes in the dial appearing in' elevation, and the end of the stripper plate also appearing in elevation. Figs. l0, 1O, 11, 12, 13 and 14 are views on an enlarged scale illustrating the inking mechanism detached, Fig. 10 being a section on the line 19 p in Fig. 11, and Fig. 11 an end elevation,both of said views showing the position of the parts when the inking rollers are taking ink from the ink supply rollers, Fig. 12 being a side elevation showing the parts at the completion of the forward movement of the inking rollers, Fig. 13 being a similar view showing the position of the parts at the instant a wad is being printed, the inking rollers being at their retracted position as in Fig. 10 but the ink supply rollers being out of operative position, and Fig. 14 being a .detail view illustrating the special mechanism for rotating one of the inking rollers the point of view being opposite to that in Figs. 12 and 13, said view being in fact a section on the line p p in Fig. 11 but looking toward the right, 2'. e.-in the opposite direction from that indicated by the arrow; Fig. 15 a detail sectional view on an enlarged scale illustrating .the construction of certain mechanism under the bed, which is shown clearly in elevation in Fig. 2; Fig. 16 a similar view illustrating the construction of the lower end of the wad tube; Fig. 17 a similar view illustrating the construction and adjustment of the lower ink distributing table; Figs. 18 and 19 are similar views illustrating the adjustment of the dial feed pawl, and Fig. 20 is a detail plan view of the tube holder detached.
1 denotes the bed of the machine and 2 suitable legs by which it is supported.
Power is applied to drive the machine by a belt not shown running over a pulley 3 on the shaft 4 journaledin boxes 5 upon a standard, 11. e., a heavy casting 6, which rests upon the bed, s mid standard being held in position by bolts 7 which extend upward through the bed and'engage threaded holes in the base 8 of the standard.
9 denotes a disk at one end of shaft 4 having a cam groove 10 which is engaged by a roller 11 carried by a slide 12 which carries the upper printing die or types as will be fully explained.
13 denotes a bevel gear on shaft 4 which engages a'corresponding bevel gear 1t on a vertical shaft 15 which is journaled in upper, middle and lower bushings denoted respectively by 16, 17 and 280, bushing 16 having a flange 18 which rests upon a web 19 in standard 6, the bushing extending through said web, bushing 17 having a flange 20 which rests-upon the-top of thebed, the bushing itself-extending through thebed as shown in Fig. 5, andbushing280 having a flange-28l which-restsupon a casting 282 secured tothe i under side of the bedbymeans of bolts or screws-283, see Figs. 2 and 4, said bushing extending through the casting as-shown in Fig. 5. At the lower end of shaft 15 is a bevel .5 gear 284 which engages-a corresponding bevel with the exception of the printing dies or typesaredriven by means of disks 21, 22,. 23
and-'24 on shaft 15, disk 2l being above thebed,and; disks 22, 23 and 24 being below the bed,and each of said disks being provided 1 with a cam groove, saidgrooves being denoted respectively by 25, 26,27 and 28,- cam groove25 being in disk 21, &c.
For convenience in description I will state here that the mechanism by'which the wad carrying dial. is moved is driven from disk 21, the inking rollers are-driven'from disk 22,
theink distributing tables are driven from' disk 23 and theink supplying-mechanism is driven from-disk 24;.
The wads are fed to. the machine in tubes 29:each.wad tube being provided with a cutoff 30-in'its lower end and a weight 31 being placed above: the wads in the tube to .force theme-downward. The wads are placed in the tubes in any suitable manner and when a tube is-exhausted another one is put in its place and the cutoff drawn out to letthe wads pass down-ward. The'machine does notrequire to be stoppedin changing tubes.
and 16. At the inner end of this bracket is a head 247'having a slot 248m one side, and
.on opposite sides of the slot cars 249, through which a screw 250 passes, see Figs. 2 and 4..
Oneend only of this screwis threaded the other end passing loosely through the ear and being provided with a head 251 adapted to be engaged by a hand piece 252 for conven- The wads as L theyleave thetubes pass into a wad receiver 32 which is carried by a bracket 33, see Figs. 3
ience in operation. The hand piece is made detachable, but is ordinarily allowed to remain on the head so that if necessary the wad receiver may be removed without an instants delay and a new one substituted and clamped in place by a movement of the hand piece. From the wad receiver the-wads pass into holes 34 in adial 35. The edge of the dial, 216., the operative portion, is made the exact thickness of the wads themselves, the central portion of the dial being made thicker, see Fig. 8, and being attached by means of screws 36 to a drum 37 the periphery of which is provided with teeth comprising a ratchet 38. The
drum and ratchet lie in a recess 39 in a casting 40 which is movable transversely to the bed in the mannerwhich I will presently describe. The dialturns upon a standard 41' which extends upward through the casting said standard being provided with ahead 42- and being locked in positionby asetscrewpassing through thehead-and engagingsthe casting. The edge of the dial rests=upon a ring 291 which lies in a-recess 331 in casting 40 and is secured to the. casting by-screws: 292.
The casting is also provided with a vertical recess 332 to receive thelowerplnnger see Fig.
.7, with a transverse recess 333,-see Fig. 1 in connection with Fig. 7-whichpermits the lower inking roller to. pass over the surface of the lower-die or types as will be mor'efully explained and with a recess 334,-see Fig. 7, which receives the edgeof the lowerinking table. This recess does not appear inany other view'and is not of the essence of my invention, it being-merely a removal of metal to accomodate oneof the operative parts. After the wads have been placed inholes 34 inthe dial they are-carried .ove'rthe surface of the ring, the partsbeing tittedv so accurately that but one wad can passinto a hole at a time thereby wholly preventing any cloggingof the wads. "This ringis provided with a hole 315, see Figs. 5 and 8, which registers with one of the holes in the dial and with the upper and lower dies or types. Theprinting of the wads takes-place at this point aswill bemore fully explained.
83, see Fig. 7, denotesanotherholethrough ring 291, through casting 40-and through the bed. This hole registers with atube.3l6,see Figs. 2 and.3, through which the printed wads are expelled from the machine as will presently be fully described. Between-holes 315 -and 83 in ring 291 there is formed a:curved printiswholly prevented and the inkorr both sidesof :theprinted wad is permitted to dry more or less during the time that elapses'between the printing of the wad and the instant of its expulsion from the machine. The upper end of the standard is reduced and screw threaded to receive a curved spring disk 43 which bears upon the top of the dial, the pressure of the spring disk on the dial being adjusted by a nut 44 engaging the threaded end of the standard, and said nut being locked in position by a lock screw 215. This construction will be found clearly illustrated in connection with another part of the machine in Fig. 15, which see in connection with Fig. 8. This spring disk is in practice so adjusted as to produce sufficient friction to stop the forward movement of the drum and dial the instant the application of power to the ratchet ceases.
The construction of wad receiver 32 and bracket 33 by which it is carried will be clearly understood from Figs. 3, 4, 8 and 16. The wad receiver is provided with slots 49 in order that the operator may see if the wads are feeding properly, and with an external screw thread 50. The lower end of the wad receiver is passed through a hole in the bracket in which it is adjusted vertically by means of a nut 51 which engages the thread and rests upon the top of the bracket, being held therein by screw 250 engaging ears 249 as already described. After adjustment nut 51 is locked in position by a check nut 52. In addition to this vertical adjustment the wad receiver has an adjustment toward and from the dial and also alateral oscillatory adjustment. The bracket carrying the wad receiver is carried by a stud 53 which lies in an opening 54 in casting 40. The stud is made fiat sided and the opening shaped to correspond therewith so as to prevent the stud from turning therein, see Figs. 7 and 8. The stud is also provided with a collar 55 which rests on the bottom of an enlargement of the recess. The upper end of the stud is threaded and is engaged by a nut 56. The lower end of the stud is also screw threaded and is engaged by a nut 57 which bears against a washer 58, the latter engaging the under side of the casting, this portion of which overhangs the supporting plate 59 upon which the casting is adjustable as will be more fully explained.
The adjustment of the wad receiver toward or from the dial is effected by means of a screw 60 which turns freely in thecasting and engages stud 53, said screw being provided with a collar 61 which lies in a corresponding recess of the casting, and being retained in position by means of a plate 62 secured to the outer side of the casting. The outer end of the screw is squared as at 63 to receive a wrench when it is required to adjust the wad receiver in or out relatively to the dial. The
oscillatory-adjustment of the wad receiver is efiected by means of a screw 64 which passes through a block 65 on the casting and bears against an arm 66 extending outward from bracket 33, see Fig. 4.
Should it be required at any time to adjust the wad receiver toward or from the dial nut 57 is loosened and screw 60 turned toward the right or left as may be required to impart the required inward or outward movementto the bracket and wad receiver. After the parts have been adjusted they are locked in position by tightening up nut 57.
Should it be required to give to the wad receiver slight lateral adjustment nut 56 is loosened and screw 64 is turned either in or out as may be required, it being of course understood that the end of said screw bears at all times against arm 66. Having secured the desired adjustment of the wad receiver and bracket, the parts are locked in position by tightening the nut 56. In order to prevent the possibility of screw 64 moving to the slightest extent in use I provide a check nut 67 which must be turned backward before the screw can be turned. Having set the screw to give the required adjustment to the bracket it is locked there by tightening up the check nut. The lower ends of the wad tubes simply fit down into the upper end of the wad receiver which is made just large enough to receive them.
The upper ends of the wad tubes are supported by springs 68 secured to a block 69 upon an arm 70 extending from the upper end of a rod 71, see Figs. 1 and 6, the lower end of said rod being rigidly secured in arm 66 of bracket 33. The springs are curved as at 72 to just receive and hold the tubelock ing it firmly in position but permitting it to be easily removed when exhausted and a filled tube substituted in its place.
In addition to the adjustments of the wad receiver just described casting 40 is movable bodily transversely of the bed, carrying with it the dial, wad receiver, wad tube and the va: rious parts just described. Supporting plate 59 upon which the casting rests is rigidly se cured to the bed and is provided with a dovetail 73, this dovetail engaging a corresponding way in the under side of the casting, a'gib 74 being placed between the dovetail and the way, said gib being adjustable by set screws7 5 which are provided with lock nuts, see Figs. 2 and 3. This construction enables me to move the dial and all the parts operating in connection therewith out from under the dies or types should it be necessary to remove any of said parts from the casting for any purpose whatever.
At one end of supporting plate 59, see Fig. 8, is a block 76 through which a screw 77 passes. The inner end of this screw serves as a stop to determine the inward movement of casting 40 in movingit back to place. I-Iaving once given to screw 77 the proper adj ustment it is secured in position by a lock nut 265. Intermittent rotary motion isiinparted to the dial by means of a pawl 78 pivoted to one arm of a lever 79. This lever is practically a bell crank lever, the two arms being at approximately right angles to each other. The lever is provided with a sleeve 80 which turns on a stud 81 extending upward from the bed, said stud constituting the fulcrum The. pawl is retained in-engageof the lever. ment with the ratchet by means of a spring 82 one end of which is connected to the pawl, the other to the lever.
The specialconstruction of pawl 78 is clearly sided and of greater size one way than the other. This flattened portion passes through a slot 256 at the inner end of the inner arm of bellcranklever 79.
2"? is a setscrew in-lever 79 the inner end of which passes into the slot and against which one edge of portionv 255 of the stud.
rests. This set screw is locked in position after adjustment by check nut 258. Theupper end of stud 253 is reduced and threaded as at 259, said threaded portion being engaged by a nut 260 which bearsagainst the shoulder at the lower end of the reduced portion. The lower end of said stud is also threaded and is engaged by a nut 261.
It will of course be apparent that nut 260, will retain the pawl in position on the stud and nut 261 will hold the stud in position in the slot in lever 79, the tightening up of the nut drawing the collar against the leverr Stud 253 is additionally. held in position by the set screw 257 it being apparent that the pressure in useis all in the direction of the screw. This set screw afiords a very fine adjustment in setting the pawl in position and also serves as astop to. prevent the stud which carries the pawl from being moved out of position after adjustment. At the inner end of the pawl is an angle arm 262 which is provided with a hand piece 263 for convenience in disengaging the pawl from the ratchet when it is desired to move casting 40 and the parts carried thereby out from under the dies or types.
264. is a stop pin in lever 79 which prevents the possibility of the-pawl being thrown far enough away from the ratchet under any circumstances to permit it to become permanentlydisengaged. Should thepawl bethrown violently away from the ratchet arm 262 will come in contact with the stop pin and the pawl will at once drop back to place. At the outer end of the other arm of lever 79 is pivoted a segmental slide, block or shoe 266,.see Figs. 4 and 7, which engages cam groove 25 in disk 21, each rotation of said disk causing an oscillation of the arm carrying the pawl and I consequently producing a backward movement of the pawl over theface of the ratchet anda forward movement of the pawl which carries the ratchet and with it of course the moving any farther than the exact distance they are carried by the pawl, by the pressure of spring disk 43 upon the upper surface of the dial.
The wads afterbeing dropped into the holes in the dial from the wad receiver are carried around into position to be acted on by the .at its inner end and internally screw threaded at its outer end, andprovided with an enlargement 89 whichrests upon the end of the carrier. The threaded end of sleeve 88 extends beyondthe carrienand is engaged by a nut 91. The internal thread at the outer end of the sleeve is engaged by a flanged nut 92. An adjusting screw. 93 passes through the flanged nut and bears upon a washer 94. within the sleeve. 1 A coil spring 95 is interposed between the plunger, and the washerfthis spring being sufficiently rigid to insure a perfect print upon a wad but atthe same time yielding sufficiently to prevent the slightest injury to the type under any circumstances. In practice the flanged nut'is screwed down tight upon the endof enlargement 89. Adjusting screw 93 is turned in forcing the washer inward as far as may be required to give the required rigidity to the spring. When the screw has been properly adjusted it is locked in position by a set nut 96. On the inner side of each. carrier is a lug 97 which may be cast separately and secured thereto as shown in the drawings, ormay be .cast integral therewith if 1 preferred. This lug is internally screw threaded to receive a screw 98 by which the carrier and the various parts moving therewith may be adjusted vertically.
The head of each screw 98 restsupon, and said screw turns freely in, a lug 99 extending from one of the slides (12 or 290) said slides being provided with grooves 100 to receive lugs 97 on the carriers, lugs 99 on the slides being directly in line with lugs 97. The head of each screw, denoted by 267, is secured in place by a pin and is provided withholes to receive a turning, red, said screws being also provided with collars 268 which lie on the inner sides of lugs 99, and act to hold the screws against endwise movement except as carried by the slides. The portions of the screws which engage lugs 99 on the slides being unthreaded and the portions engaging lugs 97 on the carriers being threaded, it follows that rotation of the screws must necessarily move the carriers and accompanying sible adjustment. The upper slide is provided on its inner face with a roller 11, and the lower slide with a roller 289 which engage respectively cam grooves and 288 in disks 9 and 287, each rotation of said disks acting to impart a complete reciprocation to the slides. The inner and outer sides of the slides are both shaped to form dovetails,
the outer dovetails lying in correspondingly shaped grooves 101 in the carriers and the lnner dovetails lying in the correspondingly shaped grooves 102 in plates 103 and 293 which are respectively rigidly secured to standard'ti and to casting 282 in any suitable manner, for example by heavy screws as shown in Fig. 5. Gibs 10. are provided on both sides of these dovetails, said gibs being adjustable by means of set screws 105 which are locked in position after adjustment by check nuts 106.
In order to prevent the upper and lower dies or types from striking each other should there be no wad between them when the inward movement takes place I provide means which I will now describe for limiting the movement of each plunger and consequently of the die or types carried thereby. Thelower plunger 85 by which the lower die or types are carried passes through a bushing 269 which passes through the bed and is provided with a flange 270 which rests upon the bed. The portion of the bushing below the bed is threaded as shown and carries three nuts indicated respectively by 271, 272 and 273. Nut 271 is turned up tight against the under side of the bed to lock the bushing rigidly in position. The lower nut 273 serves as a stop and is engaged by a block 274 which is rigidly secured to the lower plunger 85 in any suitable manner as by a pin 275. I have shown nut 273 as provided with a flange 276 on its lower side which is engaged by the block. This flange simply adds thickness to the central portion of the nut which engages the screw thread. The upward movement of the lower plunger is regulated by placing nut 273 at the exact position required and looking it there by turning nut 272 down upon it tight, the latter not serving simply as acheck nut. The downward movement of the upper plunger 85 is determined by the engagement of a block 277, which is rigidly secured to the plunger by means of a pin 278 or in any suitable manner, with a stop plate 294 the outer end of which partially incloses the. upper plunger as indicated in Fig. 5 so as to pro vide ample surface for engagement by the block. The shape of this plate may be readily understood by reference to Figs. 1, 3 and 4 in connection with Fig. 5. It will of course be apparent that the exact shape of this plate is not of the essence of my invention, it being groove 296 in standard 108 presently to he described which carries the inking mechanism, see Fig. 3. Block 295 and with it the 299 is a set nut which is turned down to lock the screw in position after adjustment. As already stated block 295 slides in a groove in standard 108, it being immaterial whether the entire block engages the groove or whether thegroove is made narrower as shownin Fig. 1 and is engaged by a reduced portion of the block. The block and stop plate are rigidly secured in position after adjustment by a bolt 800 which passes through a slot 301 and engages standard 108. It will be seen that I am thus enabled to give a very fine adjustment to both upper and lower plungers.
It is of course required in practice that the die or types carried by both plungers strike the opposite sides of the Wad with sufficient force to give a clear and sharp impression upon the wad. On the other hand it is absolutely necessary that the upper and lower dies or types should be prevented from coming in contact with each other should there be no wad in the special hole in the dial which registers with the dies or types when the inward movement takes place. accomplished by the adjustment just described.
It will be seen that the several exceedingly fine adjustments just described enable me to secure what is practically absolute accuracy in adjusting the parts, it being practicable to take up wear from use in any portion of the machine so as to retain perfect accuracy of adjustment for any reasonable length of time.
It will of course be understood that the several parts of the machine are timed to correspond with each other, each rotation of shaft 4: causing a forward movement of the dial, presenting a new wad to be printed,and also causing a reciprocation of the slides, carriers, types, &c., whereby the wad is printed on both sides. After receiving the impact of the type in printing the wad is prevented from being lifted out of the hole in the dial by means of a stripper plate 302, see Figs. 1, 4, 5 and9, which is provided with an attaching arm 335 having a slot 336, and is secured to a bracket 303 by a screw 304, which passes through the slot. This stripper plate is provided with a hole 307 which is adapted to register with the holes in the dial but is smaller so as to prevent the possibility of the wad being drawn out from the hole in the dialwhen the upward movement of the upper plunger takes place. At the outer end of the stripper plate on its under side, see Fig. 9 isacurved groove 337 which extends from hole 307 to the edge of the stripper plate at one side of the center. The location of this groove when the This is made by the upper die or types and its purpose is to prevent. the print upon the upper side of the wad from being blurred by the stripper plate as the printed wad is carried along by the dial. There is ordinarily no plate but under certain circumstances however, the edges of the wads may be sufficientl y ragged to prevent the wads from fitting perfectly inthe holes in the dial so that contact between the wads and stripper plate is possible. This however, does not affect the operation of the machine to the slightest extent and owing to the fact that the printed portion of the wad is under groove 337 blurring of the print on the upper side of the wad is made impossible, blurring of the print on the under side being made impossible by groove 317 in ring 291; It is of course essential that this stripper plate be capable of very tine adjustment. This I accomplish in the manner which I will now describe and which will be clearly understood from Figs. 9 and 9. The vertical adjustment isobtained by means of a screw 305 which passes through the stripper plate and bears upon the top of the bracket.
To raise or lower the stripper plate it is simply necessary to loosen screw 304 and turn screw 305 in or out as may be required. Having obtained the desired adjustment screw305 is locked in position bya checknut 306,. and the bracket is locked in-position-by turning in screw 304. Bracket 303 is secured to the bed by a bolt 308 which passes through slot 309 in the base of the bracket. This slot permits the'bracket and stripper plate to be adjusted longitudinally relatively to the dial as will be clearly understood from the drawings. The adjustment is elfected' by means of a screw 310 which passes through the base of the bracket in the horizontal plane and bears against bolt 308. After the bracket has been given thenecessary longitudinal adjust ment by means of this screw the screw itself is locked in place by turning down check nut 311 andthe bracket is lockedin place by turning down bolt 308. Transverse adjustment of the bracket and stripper plate is pro- Vided for by means of a screw 312 which passes through the base of the bracket and bears against a stump 313 whiclrextends upward through the bed.
It will of course be understood that both longitudinal and lateral adjustments are effectedbeforebolt 308 is turned down to place, the latter serving to lock the bracket itself.
' Adjusting screw 312 is provided with a check nut 31 1 by which it is locked in position after adjustment.
Turning now to Figs. 5, 6, 10 and 12 in connection with the general viewsI will describe the inking mechanism which is driven from contact between the wads and the stripper 'ard.
disks 22, 23 and 24. The entire-inking mechanism is carried by a plate 107 which is vertically adjustable on a standard 108 cast integral with or rigidly secured to aplate 109 which is itself rigidly secured to the bed by heavy screws as shown in Fig. 7. The back of plate 107 is so shaped as to form a way to receive standard 108, the standard being preterably beveled upon one side as at 110, see Fig. 1, and provided with a shoulder 111 on the other side, see Figs. 1 and 4.
112 denotes a gib having angle pieces 113 which I place between plate 107 and the stand- This gib may be set up to take up lost motion by means of set screws 114 which are provided with lock nuts 1 15. The angle pieces act to-prevent the possibility of the gib becoming displaced in use. Plate 107 is-retained in engagement with the standard by means of a plate 116' which engages-shoulder 111 in the standard and is secured to the plate by screws 117.
118 denotes a screw engaging plate 109 and having a head 119 provided with a bearing 120 engaging the under side of plate 107, and with 'holes 121 to receive a turningrod. It will be. seen that the entire weight of plate 107 and the inking mechanism rests upon bearing 120."
Should it be desired at any time to. give vertical adjustment to the entire inking mechanism, this result may beaccomplished by turning screw 118 either way as may be required to raise or lower plate 107 and the parts carried thereby.
As has already been fully explained slides 12 and 290, carriers 87 and the dies or types receive intermittent reci-procatory motion through the engagement of rollers lland 289 on the slides with the cam grooves indisks 9 and 287. It will be seen in Fig. 3 that the shape of the cam grooves is such that when the plungers are at their-retracted position they will be held stationary for an instant. The relative position of the types at this moment is clearly shown in Fig. 13. While the types are temporarily stationary'at the retracted position they are inked by means of upper and lower inking rollers 122 and'318, the former being carried by a slide 124 and the latter by a bracket 319 rigidly secured thereto. Casting 40 as already stated is provided with a recess 333, see Fig. 1, which permits inking roller 318 to pass over the surface of thedie or types carried by'the-lower plunger. Slide 12 reciprocates in a groove in plate 107, movement being imparted to said slide by means of a lever 125, see Figs. 10 and 13, said lever being fulcrumed on a stud 126 extending outward from plate 109. The lever is connected to the slide by means of a link 127 pivoted to the upper end of the lever and to the slide as at 128.
129 denotes a connecting rodone end of which is provided with a yoke 157 in which the lower end of the lever 125 is pivoted, the
"other end of said rod being pivoted between ICC ears 130 on a dove-tail slide 131 moving in ways in a block 132 which is cast integral with or rigidly secured to the under side of the bed. At the inner end of slide 131 is a roller 133 which engages cam groove 26 in disk 22 carried by vertical shaft 15, see Figs. 5 and 6. Connecting rod 129 is suitably curved, see Fig. 6, to avoid interference with block 274 on the lower plunger.
It will of course be apparent that there must be no lost motion whatever or looseness ofparts in a machine required to run with the absolute accuracy necessary in machines of this class. In order to insure the necessary perfection of adjustment even after long continued use Iplace a gib 134 between slide 131 and the block which may be set up at any time by set screws 135. Connecting rod 129 is made in two parts, one part being pro vided with a right and the other with a left hand screw thread, said threaded parts being engaged by a nut 136. It will be seen that rotation of nut 136 will either lengthen or shorten the connecting rod as may be required thereby changing the position of slide 124 in its groove in plate 107 and of course changing the position of the inking rollers. Below slide 124 in a similar groove in plate 107 is a slide 137. The shape of slides 124 and 137 in cross section is clearly shown in Fig. 3. On the sides toward each other the slides are both provided with shoulders 138 which are engaged by a plate 139 which is itself secured to plate 107 by screws 140, the sides of the slides below the shoulders being parallel. The opposite sides of the slides are inclined, said slides being widest at the bottom, the grooves being of course correspondingly under-cut to receive them. Gibs 141 are placed between the slides and plate 107 and may be set up to compensate for wearin long continued use by screws 142.
In Fig. 12 the position of the partsis shown at the instant the inking rollers are inking the dies or types and in Fig. 13 the position of the parts is shown at the instant the types are at their inward position, as in the act of printing a wad. At this instant the inking rollers are at their farthest position toward the left, that is away from the types. While the inking rollers are moving backward and also when moving forward again toward the the types, they pass over the surface of ink distributing tables 143 and 320, from which the inking rollers receive sufficient ink to ink the types for each impression.
In Fig. 10 the inking rollers are shown as receiving ink from the ink supplying mechanism this being a position of the parts that takes place only once during a pre-determined number of revolutions of shaft 15 and the operating disks, in the'present instance, once in eighteen revolutions all of which will presently be fully explained.
Before proceeding to describe the manner in which the ink is supplied to the distributing tables, I will describe the operation of the distributing tables themselves. The upper ink distributing table, 143, is carried by a verticalshaft 144 which is journaled in a hub 145 carried by a bracket 146 which is rigidly secured to the top of plate 107 by screws 147, see Fig. 4. Just above the table on shaft 144, is a ratchet 148, see Figs. 12 and 13. Above the ratchet is a screw thread 149, and at the upper end of the shaft is another screw thread 150. The vertical adjustment of the table is determined by a nut 151 which engages thread 149. After the table has been fixed at the eXact' adjustment required it is locked there by means of a set not 152. Nut 151 is held in contact with the lower side of the hub by means of a curved spring disk 153 which is provided with a central opening through which the upper end of shaft 144 passes, the tension of said spring disk being adjusted by a nut 154 engaging thread 150 and said nut being locked in position after adjustment by a set nut. 155. The special purpose of the spring disk is to cause sufiicient frictional contact between nut 151 and the hub to insure that the disk and ink distributing table shall be carried forward at each actuation of the machine the exact distance that the operating mechanism moves and no more, that is to say the friction being sufiicient to stop the movement of the ratchet and ink distributing table the instant the forward movement of the operating mechanism ceases.
The lower ink distributing table, 320, see Figs. 10 and 17, is carried by a vertical shaft 321 which is journaled in a standard 322 which extends through the bed and upward therefrom, casting 40 being cut away as at 334, see Fig. 7, to receive the edge of the table. The portion of the standard below the bed is screw threaded and is engaged by a nut 323 by which the standard is rigidly held in place. Shaft 321 carries a ratchet 148 and is provided with screw threads 149 and 150 in the same manner as shaft 144. The vertical adjustment is determined by a nut 151 which engages thread 149 and is locked in position by a set nut 152, nut 151 being held in contact with nut 323 by a curved spring disk 153 provided with acentral opening through which the lower end of shaft 321 passes and the tension of said disk being adjusted by a nut 154 engaging thread 150, the operation of the spring disk being precisely the same as the similar disk used in connection with the upper ink distributing table which has just been described in detail.
156, see Fig. 4, also dotted lines in Figs. 12 and 13, denotes a groove in the upper surface of the upper ink distributing table which receives any oil that may possibly collect upon the upper side of the table and renders it impossible for any oil to run over the edge of the table and mix with the ink on the under side thereof.
The ink distributing tables are given slight rotary motion at each actuation of the machine by means of pawls 158 pivoted to crank arms 159, see Figs. 3 and 4, extending outward from blocks which are vertically adj ustable on a rock shaft 161 extendingabove and below the bed, see Figs. 2 and 3. This rock shaft is journaled in a bracket 162, having a flange 324 which rests upon the bed and a threaded portion which extends through the bed and is engaged by a nut 325 by which the bracket is held in place.
163-is a flange on rock shaft 161 which rests upon the top of bracket 162, the weight of said shaft and the parts carried thereby being supported by said flange. 164 denotes screw threads on shaft 161. Blocks 160 are preferably connected to the rock shaft by keys and grooves so as to permit them to be readily adjusted or removed if necessary. When the blocks have been properly adjusted they are locked in position by nuts 165 above and below the blocks. See Fig. 3.
166 denotes springs secured to blocks 160, the free ends of which bear against the pawls and act to hold them in engagement with the ratchets. At the lower end of rock shaft 161 is a hub 167 having extending outward therefrom a crank arm 168 to which a connecting rod 169 is pivoted. At the inner end of this connecting rod is a yoke 170 which embraces shaft 15. This engagement of the yoke with the shaft retains the connecting rod at all times in operative position.
172 is a roller on connecting rod 169 which engages cam groove 27 in disk 23.
It will be seen from the above that each rotation of shaft 15 and disk 23 produces alongitudinal reciprocatory movement of the connecting rod, which in turn through crank arm 168, produces an oscillation of the rock shaft, the backward movement of said shaft causing pawls 158 to move backward over one tooth on ratchets 148 and the forward movement thereof causing the pawls to move the ratchets forward one tooth, the forward movement of the ratchets being stopped as already stated the instant the forward movement of the pawls ceases by friction between nuts 151 and hub 145 and standard 322 caused by spring disks 153.
Turning now to Figs. 4, 5, 10 and 12 I will describe the ink supplying mechanism.
173 is a block extending outward from slide 137. The ink supplying mechanism is carried by brackets 174 which are rigidly secured to slides 175, see Figs. 10 and 11, which are adapted to be adjusted in grooves in the block. This adjustment is eifected by means of disks 176 carried by screws 177 which engage the end of the block. The edges of the disks engage recesses cut in the inner sides of the slides as clearly indicated in Figs. 10 and 11. The disks being rigidly secured 'to the screws it follows that rotation of the 1atter will move the slides, brackets, and entire inking mechanism longitudinally relatively to the block. The slides are locked in position after adjustment by means of screws or bolts 326, which pass through slots 330 (one appearing in Fig. at) in the slides and engage the block. It is of course necessary to loosen the screws before an adjustment can be made in use. Slide 137 by which all of the parts just referred to are carried receives motion in the manner which I will now describe.
178, see especially Figs. 4, 10 and 11, is a rock shaft, one end of which has its bearing in plate 109, and the other end in a bracket 179 which is secured to the bed by screws 180. At one end of this rock shaft is an arm 181 which extends upward, see Figs. 1 and 11, and is connected to slide 137 by a stud 182 which passes through a slot 183 in the back of plate 107 and is rigidly fixed in said slide. The outer end of stud 182 turns freely in a block 184- which slides in a recess 185 at the upper end of arm 181, said block being shown in Fig. 1 and in dotted lines in Fig. 13. At the other end of rock shaft 178 is an arm 186 which extends downward and is pivoted in a yoke 187 at the outer end of a connecting rod 188. At the inner end of said connecting rod is a yoke 189, see Fig. 2, whichembraces a short shaft 190 which turns on a stud 191 extending downward from the bed. The upper end of this stud passes through the bed and is threaded to receive a nut 192. Just under the bed is a collar 193 which is drawn up against the bed when the nut is tightened up, thereby lockin g the parts firmly in position.
194: denotes a disk on shaft 190 which is made integral therewith or rigidly secured thereto, and is provided with bosses 195. In the present instance four bosses are shown on saiddisk.
196 denotes a ratchet also carried by shaft 190. In the present instance I have shown the ratchet as provided with a hub 197 and as attached to the shaft by a set screw .198. Below the ratchet is a collar 199 which turns freely on the shaft and is provided with an outwardly extending arm 200.
201 denotes a pawl atthe outer end of this arm which engages the ratchet, and 202 a spring secured to the outer end of the arm and acting to hold the pawl in engagement with the ratchet.
203 is a connecting rod one end of which is pivoted to arm 200 as at 204:, see Fig. 6, the other end being provided with a yoke v205 which embraces shaft 15. This engagement of the yoke with the shaft retains the connecting red at all times in operative position.
207 is a roller on connecting rod 203*which engages cam groove 28 in disk 24:-
It will be seen from the above that each rotation of shaft 15 and disk 24 causes a longitudinal reciprocatory movement of the connecting rod which in turn, through the oscillation of arm 200 moves pawl 201 backward over one tooth of the ratchet and when the forward movement takes place carries the ratchet, shaft and disk 191, having bosses 195, forward a distance depending upon the number of teeth in the ratchet. In the present instance I have shown the ratchet as provided with seventy-two teeth. It therefore requires seventy-two actuations of the machine, 'i. e. rotations of shafts 4 and 15 and the cam disks carried thereby, to produce one revolution of the ratchet and disk.
Upon the upper side of connecting rod 188 is a roller 208 which is adapted to lie in contact with the surface of disk 194: and to be engaged by the bosses on said disk. A spring 209 one end of which is connected to a pin 210 on the under side of the bed, the other end being connected to a pin 211 extending outward from yoke 187 at the outer end of the connecting rod, acts to hold the roller in contact with the periphery of the disk until said roller is engaged by one of the bosses 195. Each time one of these bosses comes in contact with roller 208 on connecting rod 188 said connecting rod is forced outward longitudinally against the power of spring 209. This movement swings arm 186 outward, oscillates rock shaft 178 and of course swings arm 181 which extends in the opposite direction from arm 186 inward, thereby moving slide 137 and the ink supplying mechanism carried by said slide inward toward the inking rollers, this position of the parts being clearly shown in Fig. 10 as will presently be more fully explained. It will be apparent from the above that this inward movement of the ink supplying mechanism toward the inking rollers takes place in the present instance once in eighteen actuations of the ma chine, there being seventy-two teeth in the ratchet and four bosses producing this movement on disk 194 which moves with the ratchet. This adjustment of the parts I have found to work perfectly satisfactorily in use. Should it be found necessary to supply ink more or less frequently to the inking rollers, disk 194 would be removed and a new one substituted having more or less bosses 195,
for example a disk having two, three or six bosses, it being preferable although not essential, that the number representing the bosses on the disk be contained an even nu mber of times in the number representing the teeth on the ratchet. Shaft 190, the disk, ratchet, collar, &c., are retained upon stud 191 in the manner which I will now describe. Shaft 190 is threaded at its lower end and is engaged by a nut 212, collar 199 lying between the ratchet and this nut, the nut being screwed up tightly enough to prevent lost motion but without interfering with the free movement of the collar. It is of course essential however, that the ratchet shall not be carried forward any more than the exact distance the pawl moves. This result I accomplish by a friction device similar to the ones used in connection with the dial feed ratchet, and the feed ratchets which carry the ink distributin g tables. The lower end of stud 191 is screw threaded and is engaged by a nut 213.
214 denotes a curved spring disk having a central opening through which the lower end of the stud passes. The edge. of this disk have been correctly adjusted nut 213 is locked in position by lockscrew 215 which engages the end of said stud, the head of said screw engaging the outer face of the nut.
216, see Figs. 4c and 10, denotes masses of thick ink in boxes 217, having at their forward ends ink-supplying rollers 218 which are preferably corrugated. These rollers are carried by shafts 219 journaled in the sides of the boxes. Within the boxes are slides 220, the forward ends of which extend partly under rollers 218 and act to determine the quantity of ink that can be taken up by the ink supplying rollers the slides when moved up in contact with the rollers acting as scrapers and when moved back slightly permitting a limited quantity of ink to pass through the openings between the slides and the rollers and to be taken up by the rollers. At the rear ends of the boxes are blocks 222. The rear ends of the slides extend through these blocks and are engaged by screws 223 carrying disks 224, which engage recesses cut in the rear ends of the slides, see Figs. 10 and 11. The disks being rigidly secured to the screws it follows that when the screws are turned in or out in the blocks the engagement of the disks with the slides will move the latter in or out relatively to the ink supplying rollers thereby regulating the size of the openings and consequently the quantity of ink taken up by the rollers. Slides 220 are locked in position after adjustment by means of screws 327 which pass through slots, not shown, in the slides and engage blocks 222. In making an adjustment these screws are slightly loosened and are then tightened up again. The position of rollers 218 is changed axially at each backward movement of the boxes by the mechanism which I will now explain.
225, see Figs. 11 and 14, denotes ratchets on shafts 219, these ratchets as well as the rollers being rigidly fixed to the shafts.
226 denotes arms which swing on shafts 219 and carry pawls 227 which engage the ratchets, said pawls being held in engagement with the ratchets by springs 228. At the lower ends of arms 226 are rollers 229 which engage slots 230 in uprights 231 and 328 the bases of which are rigidly secured to the bed by screws 232, and 329.
.233, see Figs. 4, 11 and 1 1, denotes shafts which'are adapted to turn in swinging arms 226 and carry at their inner ends lugs 231 which are adapted to engage corresponding lugs 235 extending outward from the rear ends of pawls 227. Shafts 233 are provided
