ARTHUR SABORSKY, 0F LAKEWOOD, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO

THE ADVANCE MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORA- TION OF MAINE.

PRINTING-MACHINE.

Specification of Letters Patent.

Patented Feb. II, 15H9.

To all whom it may concern:

Be it known that I, ARTHUR SABoRsKY, a subject of the Emperor of Austria-Hungary, residing at Lakewood, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Printing-Machines, of which the following is a specification.

One object of the invention is to provide a simplified form of construction adapted to print matter upon blanks successively.

Another object ofthe invention is to provide a machine having parts which work automatically to reduce to a minimum the labor required to operate the machine.

Another object of the invention is to provide an improved printing machine adapted to print or impress subject-matter upon one side of a series of blanks, such as cards, and to print the same or constantly changing subject-matter upon the opposite side of a series of blanks.

Another object of the invention is to provide an improved printing machine in which separate printing mechanisms are correlated for conjoint or separate operation whereby a series of blanks can be printed with the same subject-matter on either or both sides, or different subject-matter printed on one side of each blank.

The invention has reference to that class of printing and addressing machines in which a series of blanks are fed one at a time to separate printing positions and in which a series of printing slugs are first stored in a magazine from which they are automatically propelled to the printing position of the minor printing ,device and thence in turn are propelled to a separate magazine into which they fall by gravity onto an automatically movable support.

I preferably provide yfor the removal of the slug storing magazine and its alinement with the slug receiving magazine so that the used slugs can vbe transferred back to the storing magazine in a simple manner and the latter replaced by-a magazine filled with a new series of slugs.

The invention includes automatically acting mechanism whereby the blanks will be propelled with precision to the main printing device, which is shown to be preferably a rotating drum or segment, `and in which the movements of the drum control the movements of feed rollers for the blanks, so that the speed of the peripheries of drum and feed rollers will always be substantially equal and no slip can occur.

The invention also includes a reciprocating device, hereinafter called a shuttle, for automatically transferring the addressing slugs or cards from the magazine, which may be removable, to their printing position, and-for automatically returning them to another magazine, which may be stationarily arranged in alinement with the reinovable magazine.

It includes a reciprocating plunger which receives the slugs from the shuttle, impresses them upward against the blank and then lowers them, whereupon the aforesaid shuttle removes them from the plunger and transfers them to a magazine. It also includes automatically acting mechanism for lowering the addressing slugs in the magazine, the distance of the thickness of one slug as fast as they are transferred from said plunger.

The invention includes an upper detachable magazine and a lower fixed magazine, which are provided with alined openings through which the slugs collected in the lower magazine can be elevated and restored to the upper magazine.

The invention further includes intermitting'mechanism for operating the reciprocating slug transferring shuttle at times when the plunger is not in motion, and intermittin mechanism for feeding the blanks between t ie printing strokes of the plunger, thus permitting the slugs to remain under the blanks in printing position while the impression is being made thereon.

The invention includes also a cam for operating the plunger which impresses the slugs upon the blanks and which is provided with two rest surfaces, one permitting the deposit of the slugs upon the plunger, and the other permitting the removal of the slugs therefrom.A

The invention accomplishes the desired objects heretofore enumerated by means of the combination and arrangement of parts and construction of the various details hereinafter described, exemplified in the accompanying drawings and specifically pointed out in the claims, but modifications thereof can be made which do not depart from the scope of the claims.

In the accompanying drawings Figure 1 is aside elevation of a printing machine embodying my invention. Fig. 2 is a plan view of the movable shelf in the lower magazine; Fig. 8 is a fragmentary vertical section through the lower magazine and shelf; Fig. 4 is a transverse section thereof; Fig. 5 is a plan view of the machine; Fig. 6 is a side elevation of the machine opposite that shown in Fig. 1, showing the m-ain operating shaft therefor, and connections for the blank feed rolls, both magazines being omitted; Fig. 7 is a longitudinal section of the machine showing the main printing drum and plunger which impresses the addressing slug u-pon the blanks, and also the racks which operate the slug transferring device, and also the -blank feeding devices; Fig. 8 is a front elevation of the machine; Fig. 9 is a rear elevation of the machine; Fig. l() is an enlarged transverse section through the machine on the center line of the printing position for addressing slugs, showing the plunger, the guides for the slugs, and the alunffer guide Fio. 13b is a. sectional view h b 5 D showing one of the two cams for adjusting the pressure roller relatively to the printing cylinder; Fig. 13C is a longitudinal section of coupling for the divided cam rod; Fig. 131 is an elevation thereof showing a scale for angular adjustment; Fig. 14 is a perspective view of the movable bottom for the blank holding box; Fig. 15 is a perspective view of the adjustable feeding knife which lies upon the bottom of the blank holding box; Fig. 152L is a section' showing an improved reversible form of knife edge; Fig. 16 is a detail View of the adjusting gear for the eccentric on the sleeved shaft which operates the blank feeding bottom of the card box; Fig. 162L is a side elevation thereof; Fig. 17 is a perspective view of one of the addressing slugs; Fig. 18 is a side elevation of the locking device for the crank which operates the shuttle moving mecha.- nism; Fig. 19 is a plan view thereof; Fig. 20 is a side view of the locking cam therefor.

In the drawings, 1 is the frame of the machine; 2 is the main driving shaft which may be operated by any suitable power and from which all the movements of the machine are preferably obtained.

3 is the printing drum which'is mounted loosely upon a shaft 6. and preferably detachably connected with the same by means of a clutch 32. The printing drum maybe operatively connected with the main shaft 2 'by means of spur gears 4, 5, 4, and 5. 3X indicates means, preferabljy7 a roller, for supplying ink to the printing devices on the drum 3. The roller 3X may be mounted on standards in any suitable manner. 3 is the pressure roller, preferably an idler, the shaft WV therefor being-'mounted in the bearings E, E,=which may be adjusted by-means of eccentrics E, E', (Fig. 13b) mounted upon a divided shaft E2. The vshaft E2 is rotated by means of a lever- E3.

E4 indicates a stop to limit the movement of-the lever E3. The stop E4 is preferably adjustably mounted, in any well known-manner, on an arc E5 which 'is fixed to the frame 1.

The shaft E2 is divided to permit adjustment of the eccentrics E independently. F

indicates a sleeve surrounding the innerends of the sections constituting the shaft E2. F2 indicates a scale (see Fig. 13d) to indicate the adjustment of the shaft.

6 is a spur gear upon the shaft 6 of the printing drum, which gear is provided with a blank portion 7, and 8 is a similar spur gear having a corresponding blank surface 9 correspond-ing fto the blank surface 7 of the gear 6. By means of thesegears the intermittent movements of the machine are obtained.

Upon the hub ofthe gear ,Sis-mounted the sprocket wheel 10 operating the chain 11, and thereby the sprocket wheel lupon the shaft 13 of one of a pair of feed `rolls 14, 14 for the (blanks. The rolls 14, 14 are preferably placedv in adjustable bearings 142, 142 in the bed plate. The feed rolls 14, 14 are provided with interlocking gears 15, 15. A second pair of `rolls 16, 16, are operated by sprocket wheels 17, 17 a chain 18 upon the lower roll shafts and spurgears 19, 19, upon the shafts of the rolls 16, 16. A platform 2O supports the blank as it is fred by the feed rolls to the printing drum.

The relative diameters of the rolls to the printing d-rum are such .that the speed of their peripheries is precisely the same, which prevents any possibility of the cylinder or drum slipping or causing* smearing of the ink upon-the blanks. The rolls are preferably formed of hard material, such as steel, which may be spring operated to firmly grip the blank between them.

At 21 is shown the boX in which the blanks 22 22, are stored. The rear wall 23 and front wall 37 of the sectional box are preferably inclined to make the rear edges of the blanks overhang one another, and a knife plate 25 having a thin edge Q5 and mounted upon a sliding rbottom 26 feeds the blanks one at a time to the feed rolls.

The movement of the bottom is also intermittent, being preferably controlled by the intermitting gears 6 and 8. The movement of the sliding bottom is designed to coperate with the movement of the rolls, and is preferably operated by means of an eccentric 30, carried by a hollow shaft 31 which is sleeved' over and adjustably secured to a gear 27 fixed to a shaft 28. The gear 27 may be drivenby a gear 29 upon one of the feed roll shafts. The eccentric 30 is arranged to engage bearing walls 32, which are provided on a member secured to and depending from the bottom 26. The walls 32 are arranged in front and rear of the eccentric 30 so as to be engaged thereby as it rotates to move the bottom 26 forwardly and rearwardly.

The movable bottom moves at less speed than the feed rolls so that when the blank comes into contact with the rolls they carry it away from the bottom until they intermit, the blank being then in the addressing position where it lies until printed.

The amount of lead or timing of the sliding bottom and knife relatively to the rolls, so as to control the position of the blank at the printing position at the opening 20a, when the address is printed thereon, and also changing the width of margin for the main printed communication, is obtained by means of an adjustable connection between the gear 27 and sleeved shaft 31, which carries the eccentric 30. In Figs. 5 and 16a, a crank 33 is shown upon the sleeved shaft 31 and a pin 34 on said crank passes through a circular slot 35 in said gear 27, and is clamped thereto by means of a nut 35a.

The relative positions of the eccentric and crank to the gear 27 and shaft 28 can then be read in the graduated edge 36 of the slot. By means of this adjustment the blank can be advanced to be engaged by the rolls at any desired period of their movement, and since the rolls rotate during a definite period only, the entire travel of the blank up to the addressing position can be determined by timing accurately the moment when the rolls first commence tol feed the blank.

The front wall 37, preferably having the same inclination as the rear wall of the blank holding box, is adjustably attached to the frame, whereby it may be positioned to prevent more than one blank from passing out at a time. The blanks pass underneath the lower edge of the front wall 37 as they are fed to the rolls, and are thereby prevented from flying up at the forward edge when passed out from under a pile of blanks.

This plate 37 is accurately adjusted to the thickness of the blank to be fed by means of camsC, C, and an operating rod C Vtherefor.

. The blank holding box comprises angular plates 21 adjustably mounted upon a bar 38 for transverse adjustment to adapt them to the size of the blanks. The bar 38 is attached to terminal angleJ bars 39, 39, which are longitudinally adjustable upon the bed plate. 40, 40, indicate set screws for securing the bars 39 in any position to which they may be adjusted.

The sliding bottom is mounted in guides 41, 41, formed in the opposite sides of the bed plate, and the feeding knife 25 is guided in grooves 42, 42, in the movable bottom, and clamped when properly adjusted by means of the screws 43, 43, as shown in Figs. 7 and 13. The knife edge 25 itself is slightly raised above the surface of the knife so as to take hold of the lowest blank.

This edge can be made adjustable to adapt it for feeding blanks differing in thickness by pivoting in a recess, B', in the knife plate a separate blade B, as shown in Fig. 15a. rlhe blade B may be provided with a multiple number of edges any one of which may be arranged for engagement with the blanks by removing the blade B from the recess B and disposing the desired edge at the forward end of the recess.

B? indicates screws which serve to adjust the blade B at different angles so as to cause its front wall or edge to project above the surface of the plate any desired distance.

Graduated scales 44 and 45 on the meeting edges of the knife and movable bottom (Fig. 5) and 46 on the supporting bracket 39, 39, for the box are shown in Figs. 5, 14, and 15, by means of which accurate adjustments can be made for the size of the blank.

50 indicates a plunger vertically movable in a suitable bearing formed in a block G which is carried by the frame 1. At its upper end the plunger 50 is provided with a head 50 which receives the address slugs S and moves them upwardly through the opening 20a. L indicates horizontal guides through which the slugs S are delivered to theplunger 50 or head 50 thereof. The guides L are provided in the walls of the block G. 51 indicates a platen against which the plunger 50 presses each slug when it moves upwardly, and this effects printing on a blank which has been delivered to a position over the opening 20a. The platen 51 may be adjustably mounted in a cross bar 52.

The platen is suspended from the bar 52 by means of screws K, K, and springs K,

l, which permit vertical adjustment. The

platen is preferably adjusted by means of the three screws V, V, V set in the bar 52 in staggered relation to each other so that the level can be adjusted in all directions.

rEhe head 50 of the plunger is provided with an extended edge H which receives thc slug and keeps it from falling off sidewise. The plunger operates upon the slug in the guide block G at a point intermediate between the two pairs of feeding rollers and the blank is held firmly by them while being printed. The plunger then falls to a lower level carrying the slug with it which is then removed from the plunger through horizontal guides L, L, in the guide block Gr.

These movements of the plunger accompanied by two rest periods of the plunger while the slug is being placed upon the plunger and while it is being withdrawn therefrom, are obtained by means of a cam 53 mounted upon a shaft 54 operatively connected with the drive shaft by means of spiral gears 55, 56, and bevel gears 57, 58, and shaft 59, thus giving the cam a continuous uniform rotary movement, speeded to equal one rotary movement of the printing drum.

Operatively connected with the intermittent movement of the machine is the device for withdrawing the addressing slugs from the upper removable magazine at the upper level L, and advances them to the plunger upon 4that level, and which, after the plunger has operated and moved downwardly until its head is in the plane of the guides L, withdraws the slug therefrom and moves it through the guides L to the lower magazine (see Figs. 5, 7, 10, 11,-12 and 13).

60 is a magazine preferably removably mounted upon a hollow head 61 of the cross bar 52. The magazine 60 is preferably provided with side ribs 62, 62, which are insertible -in grooves 63, 68, formed in the head 61. The magazine is adapted to hold a pile of slugs S and permit them to slide downwardly as one after another they are fed to the printing position.

64, 64, indicate a pair of bars arranged on opposite sides of the mouth of the receptacle in the same horizontal planes as the guides L, L, 64 indicates pairsl of spring plates fixedv in any well known manner to the adjacent side walls of 'the receptacle and the bars 64, and serving to maintain the latter normally in position to support the slugs thereon in superposed relationship (see Fig. 10). 65, 65, indicate a pair of arms mounted on pivots 65. Each of the pivots 65 is mounted in a lug 65a formed integrally with the adjacent side wall and overhanging liange of the head 61. Surrounding each pivot 65 is a spring 65h which normally operates to maintain the arms in the position shown in Fig. 11. The inner ends of the arms 65 are provided with bent ends which engage the bars 64, las shown in Fig. 11. The arms 65 extend late-rally into position to be engaged by the opposite ends of a yoke shaped lever 66 having engaging lugs 66 for operating the rock arms 65. Then it is desired to separate the bars 64, 64, to open the mouth or lower end of the receptacle, the lever 66 is swung upwardly. This operation serves to swing the levers 65 about their pivots and to move the bars 64: away from each other. When :the bars 64: are thus operated, `the opening into the upper magazine is unobstructed vand the slugs may then be moved from the lower vmagazine upwardly thereirrto, `or to a position above the .bars 64. The lever 66 is preferably pivoted =to opposite `sides 4of the head 61.

The upper edge .of the holding bars is in `the same horizontal line with the Vguides L, L at the upper level on which the slugs are fed sto the plunger. Below this finagazine yand having an opening in line with the opening in :the upper magazine is a. lower magazine Y67, the receiving end of which is placed below the lower horizontal level yof guides L, L in which the slugs are returned from the plunger, and they drop .one at a time therein upon a movable shelf B3 which automatic-ally falls the thickness of `one slug before the next is carried thereto.

The slugs pass from the aipper magazine t-o the plunger-one at a time -upon the Iupper level in horizontal .guides L in the previousl-y mentioned ,guide block G, and are returned' through the guides L in said guide block at the lower level to the lower magazine where they drop upon said shelf, as shown in Figs. 8 `and 10.

rIhe device `for imo-ving the slugs in the aforesaid guides consists of `a shuttle or reciprocating .member 71 slidably ymounted in the do-vetail guide 72 in one side wall of the guide block G This `shuttle is provided -w-ith V,an upwardly vand inwardly extending linger 73 which engages the slug at the upper level and also with the downwardly extending finger 7l which engages the slug at the lower level.

4'One of the typeholding slugs is shown in Fig. 17 and is provided with .a notch 75 which the finger'73 engages and thus perfect alinement is assured. The slug is provided with fdownwardly and inwardly turned sides 76, which an yoverhanging edge H of the plunger engages.

The finger 7 3 is provided with a pivoted pawl 7 8 spring pressed `at `76 at its outer end which moves the slug to `the plunger but passes under the slug in the upper magazine on its reverse movement. false open-'ing 79 is shown at the .other end of the slug, permitting the finger to operate properly in case the slug should by mistake be reversed in the magazine, and in this manner breaking or jamming'the slug carrier will be prevented.

The shuttle is operated to move the slugs upon the plunger and remove them therefrom when the Vplunger is at its lowerlevel are constructed and arranged so that the vtion of the frame 1.

by means of a rack 80 upon one side of the shuttle, a gear 81 engaging the rack, a second gear 82 of one thi-rd the diameter of the gear 81, the said gears secured upon a common `axis and moving in unison, the gear 81 being larger than the gear 82, and a second rack 83 which operates the gear 82 and reciprocates in a groove 84 in the frame.

This rack is given an intermittent reciprocating movement by means .of a connecting rod 85, and crank 86 mounted upon the end of shaft 28 'opposite to that to which the gear 27 is secured, and which receives the intermittent movement from the feed rolls for the blanks. l

The difference in speed of the gears 81 and 82 gives a quick movement to the shuttle, and moves a slug to the plunger and removes it therefrom to the lower magazine, in one reciprocation of the plunger.

l preferably provide means indicated as an entirety at J, for maintaining any desired slug in the printing position whereby the same address can be printed on the blanks as they are successively fed to such position. TheseV means may be provided between the cra-nk 86 and the adjacent por- Of these means, J7 indicates `a rock shaft rotatably mounted in a bearing formed: inthe hub of the crank 86. JX indicates a key fixed, to the shaft J7 and preferably provided with two wings J J 2. The key J x is preferably arranged in a slot or space provided between a pair of lugs providedV on the hub of the crank V86. J3 indicates a slot formed in the shaft 28 and arranged to receive the wing J when the shaft J Y is rocked to a predetermined position thereby locking the crank and shaft together. J 4 indicates a groove formed in the adjacent wall of the frame 1 and arranged to receive the wing J2 when the rock shaft J 7 is moved to another position, thereby locking the hub of the crank 86 to the frame 1. The wings J, J2 are constructed and arranged so that when the wing J engages the groove J3, the wing J2 is out of engagement with the walls of the slot J4; on the other hand, when the wing J2 engages the walls' of the groove J f, the wing J is out of engagement with t'he walls of the slot J 3, so that when the parts are in this latter-position, the shaft is disconnected from the crank. The key J X is flattened on one edge, as shown 'at J3, to be engaged by a spring J5, the purpose of which engagement is toV maintain the rock shaft in either position to which it may be moved. The parts just described key J f can only operate to lock rthe hub of the crank 86 tothe frame 1 when the crank has movedan addressing slug into the printing position. Y

A movable shelf B3 for the lower magazine (see Figs. 2, 8 and 4) is lowered the thickness of' one slug during the one complete movement of the plunger in the following manner.

One of the roller shafts of the rolls 16 is extended and a bevel gear 88 thereon engages a bevel gear 89 upon a vertical shaft 90. Movable up and down upon this shaft and keyed thereto is a spur gear 91 engaging an idler spur gear 91', engaging in turn the gear 912, both gears 91 and 912 being suitably mounted in the movable shelf B3. The gear 912 is mounted upon a shaft 92 carrying a worm 93. This worm engages a vertical rack 94 provided on a rod 94a depending from the head 61 and slowly lowers the shelf with the intermittent movement derived from the rolls. The vertical shaft 90 preferably makes one revolution while the intermitting gears are engaged, thus moving the shelf B3 a distance equal to the thickness of one slug.

The shelf is mounted on rollers 95, 95, in guides 9 6, 96, provided on the rod 94a. The shelf can be raised when desired to elevate the slugs in the lower magazine back to the upper magazine by first releasing the worm from the rack 94.

The release is made possible by mounting the worm shaft 92 upon a spring pressed pivoted frame 97, and this frame can be moved away from the rack by means of a pivoted pawl 98 operating upon a catch 99 on the frame 97, and a projecting ledge 100 serves as a handle to lift the movable bottom.

The rack does not extend entirely to the bottom 101 of the magazine, but a space is left in which the movable bottom can rest without further movement when the magazine is full. A similar space is left at the top of the magazine to prevent the movable shelf from being raised too high, and also, to permit the shelf to drop after it has raised the slugs to fill the upper magazine.

When it is desired to return used slugs to the upper magazine, the holding bars 64 are withdrawn, the worm 93 is released from the rack 94, and the bottom holding the slugs is raised to the top of the magazine.

In this manner the used slugs are returned to the same receptacle in which they were previously stored and arranged in the same iiXed to the spool D2. D3 indicates a disk having its periphery shaped `to form a spiral or worm. The disk D3 is fixed, preferably by a set screw D3, to the shaft 54, and meshes with the gear D5 in order to drive it. When it is desiredto unwind the ribbon from the spoelDz, the disk'D3 is moved longitudinally ofthe shaft 54 against'` a collar D7. The operations of the/various pai-'ts and intermitting movements of the machine succeed each other in the following manner:

The printing portion ofthe printing drum includes about one-half of its surface, and the drum and plunger operatingV cam are continuously inv motion. The intermitting gears control all other movements and at their first movement the feed rollscommenceto move to feed the blanks forwardly.

VVhilet-he drum is prin'tingthe communication the blank feeding member starts back, and the shuttle returns the used slug" tov the lower magazine. Themovable shelf is dropped in the lower magazine and the plunger` cam is moving the plunger up` to the The movable shelf in the lower magazineisalso 'at rest at this time.

As all the parts of the machine'are connected'togetherand correlatedito print the blanks as ythey are' successively fed from the' blank holder to the printing' positions, the element to which power is applied'may be driven at any desiredrate ofl speed;

To those skilledI in the art of making mechanism of the class described, many alterations in construction'and widely differing embodiments andapplications of my invention will suggest themselves without departing from the spirit and'scope thereof; My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
