This invention relates to printing machines of the type wherein the data to be printed is carried by movable printing devices as stencils.

The invention has particular reference to printing or addressing machines having provision for printing lists and especially duplicate lists of a part only, as the name and certain other data carried by each, or selected ones, of the printing devices or stencils.

In the use of an addressing machine in an insurance olice, for instance, each of the stencils or printing devices may contain the name of the policy holder with the amount of the policy in one line of the stencil and other data on other lines of the stencils. At times it is desirable to compile lists of the names of selected ones of the policy holders and the amounts of the policies without at the same time printing the other data contained by the stencils and an object of the pre-sent invention is an improved form of machine for this purpose.

It is also desirable to print duplicate lists of the names of the policy holders and the amounts of the policies and a further object of the invention is an improved form of machine for this purpose.

In accordance with this invention and as an object thereof the duplicate lists are secured to a movable holder and mechanism is provided for eiecting two printing operations upon the same stencil and for moving the holder to position the separate lists in succession in printing relation with the stationary stencil so that a separate list will be printed at each printing operation and then to advance both lists into position to receive on a succeeding line of the lists the data of a succeeding stencil.

ln the present machine, the list holder is advanced by .a reciprocating link that makes one complete cycle for each printing operation. The list, however, is intended to be advanced once for each two printing operations. Hence a further object of the invention is the provision of mechanism for so controlling the list advancing mechanism that the link is effective in advancing the list at alternate cycles only.

The machine of the present invention is arranged to advance the stencils between every two printing operations, when the successive stencils are such that the printing of the data carried thereby is desired. When, however, the data of a. stencil is not desired to be recorded, it is esirable to pass that stencil and advance to the next stencil to be printed from as rapidly as possible in order to save time. Hence a fur- 1935, Serial No. 15,593

(Cl. lill- 47) ther object of the invention is the provision of mechanism for effecting the advance through the printing position of stencils that are use-d for printingrevery other cycle of operation of the machine and for advancing unwanted stencils 5 every cycle of operation.

The printing machine embodying the present invention is providedl with selector mechanism to determine which stencils of the collection shall be used for printing. It is common to opw erate the selector mechanism to feel a stencil at each printing operation. In the present instance, however, this method of operation will result in an improper operation or the machine and hence it is an object of the present invention to provide mechanism that controls the selector mechanism in such manner that the selector mechanism is operated to feel a stencil but every other cycle, or printing operation, of the machine.

Further objects of the invention reside in a novel construction of the list holder and in the mechanism for advancing the holder.

A yet further object is generally to improve the construction and operation of printing and addressing machines.

The printing device used in connection with the present invention comprises a stencil 22 having a window therein occupied by a stencil sheet 24 bearing lines of printing data of which one line 26 may have the name of the holder of an insurance policy and the amount of the policy, and other lines 28 may contain various desirable data.

The machine of the present invention is intended to print the data of a certain part only of the stencil, as the data of the line 26, in duplicate upon a list, such as the list 30 of Fig. 19, such list having a panel 32 therein to receive the various names of selected stencils and a series of lines 34 arranged in a vertical column in which the data of the lines 26 of the selected stencils In the present instant two such lists are placed side by side and the machine is arranged to present the selected data of a stencil in duplicate on both lists.

The stencil 22 is provided with one or more selector perforations 36, or equivalent means, suitably positioned in the stencil, in accordance with well known practice, to permit the selection for printing of certain stencils only of a collection.

The machine embodying the present invention comprises a frame including a table or bed 38 supported on

legs

40 and 42. A pair of stencil rails 44 are spaced above the top of the table and extend in horizontally spaced parallel relation over the table and constitute a track in which the successive stencils 22 are advanced from a vertical stack of stencils contained in a stencil holder 46 located above one end of the track and through a printing position and into a stencil receiver 48 located at and depending below the track at the other end thereof.

The printing mechanism, see especially Figs. 1, 2 and 3, includes a vertically movable printing head 50 located above the stencil track and a vertically movable anvil 52 located below the stencil track. The printing head is provided with an impression pad 54 having a raised or stencil engaging section 56, see also Fig. 13, that is adapted to engage only with the line 26 of the stencil so as to print the data carried by this line only, the remainder of the impression pad being free from contact with the stencil. The printing head 50 is carried by the forwardly extended ends of arms 58 that are carried by a horizontal loop frame 66 disposed at the rear of the stencil track and pivoted on a shaft 62 carried by a bracket 64 secured to the under-side of the table 38. The raised portion or ledge 56 of the impression pad is suppliedwith ink by means of a horizontally swinging inking roller 66 that reciprocates forwardly and rearwardly over the face of the impression pad and into and out of rolling contact with the lowerrnost one of a series of ink conveyor rolls 68 which receive ink from a distributing drum l0, see Fig. 1, that is supplied with ink from an ink reservoir 12.

The construction of the printing head and the inking mechanism therefor is described and claimed in my copending application Serial No. 5,944, led February 1l, 1935, and need not be further described here.

The platen 52 is mounted between and is integral with the forward ends of arms 14 that are pivoted at 16 to the rear part of the bracket 64. The platen and the printing head are adapted to be reciprocated toward and away from each other in timed relation so that the platen supports a work sheet beneath and in contact with the stencil at the time the printing head moves into pressure engagement with the stencil.

The operating mechanism for reciprocating the printing head and anvil includes a horizontal shaft 'I8 supported by the bracket 64 and providing pivotal support for an operating arm which isV reciprocated in a vertical direction. Said arm is pivotally connected through a toggle link 82 with the lower end of an arm 84 depending frorn the loop frame 66 of the printing head so that the reciprocation of said arm 80 effect-s the reciprocation of the printing head. The reciprocation of the arm S0 also eiects the reciprocation of a generally vertically extended cam arm 86 having an upper cam face 88 that cooperates with a cam roller 98 carried by the platen for effecting the reciprocatory movements of the platen.

The arm 86, see especially Fig. 4, has a latch 92 pivoted thereto which is normally biased to hold its latch projection 94 within a notch of an operating sector 86 that is pivoted on the shaft 'i8 so that the arm 8U and sector 96 normally reciprocate in unison. The engagement of the latch with the sector, however, is under control of the selector mechanism and is at times disengaged from the sector as will be explained later. The sector 96 is reciprocated by means of a connecting rod 98 from a power plant |68, see Fig. l, of vwell known construction having mechanism under control of a foot pedal |62 that effects one complete reciprocatory movement of the connecting rod and hence one complete cycle of o-peration of the machine for each depression and immediate release of the pedal. When, however, the pedal is held down by the operative, as is the case with normal operation of the machine, the machine will operate continuously.V

The lists, such as the list 36 of Fig. 19, on which the data of selected stencils is adapted to be printed, is carried removably by a holder that is capable of step by step, or line by line, advance toward the printing position and also is capable of reciprocatory movement in a transverse direction. The list holder, see Figs. l, 2, 3, 4 and 12, includes a guide bar |64 that is secured to the table 38 of the machine in front of the printing head and projects forwardly at right angles to the stencil track. The bar is provided with a longitudinal Tslot and forms a guideway for a slide bar |06 of the stencil holder, which slide bar is T shaped in cross section to fit the groove of the guide bar. A plate |08 is secured at its median line to the top face of the slide bar and projects laterally in both directions therebeyond. A pair of undercut spaced parallel plates HEI are secured to the forward end of the slide brut once during this dual printing, mechanism is provided herewith for rendering every alternate reciprocatory movement of the list advancing link |60 ineffective in advancing the list holder. Said mechanism, see Figs. 1 and 3, includes a multi-lobecl cam disc |90, a notched brake disc |62, and a multi-toothed ratchet disc |94 pinned or otherwise secured together in the order named and mounted rotatably upon a stud shaft xed to the depending bracket |96 carried by the table 38 under the list advancing link |60. A ratchet arm |98 on the stud shaft is mounted concentrically with the cam and ratchet discs and is connected to the link |66 by a pin 200 which pin operates in a generally vertically positioned slotl 202 of said arm. Thus said arm |98 is reciprocated concurrently with said link |60.

Said arm |98 is provided with a pawl 204 that engages the teeth of the ratchet disc |94 and thus the ratchet and cam discs are caused intermittently to advance or rotate in a counterclockwise direction at each forward stroke of the link |60. A flat spring brake strip 265 is secured to and depends from the table 36 and has a reexed end which is adapted to enter successive notches of the notched brake disc |62, whereby to hold the set of discs releasably in any moved position thereof.

The link |60 is provided with a depending lug 208 which at its lower end carries a cam roller 2| 6 that at all times rests in contact with the cam disc |90. The cam disc is provided with a plurality of lobes 2|2 and thus the link 60 is supported either in an elevated or in a lowered position depending upon whether the roller 2|0 is upon the top part of a lobe or is inthe valley between two lobes. When the roller 2|0 is on top of a lobe the forward end of the link |60 is in elevated position and hence the latch |16 thereof can b-e engaged with one of the teeth |80 of the slide bar |16 of the list holder to advance the list. The front faces 2| 4 of the lobes 2|2, that is those faces that are directed towards the front of the machine, are substantially rectilinear -so that when any face is under the roller 2 I0, as

illustrated in Fig. 3, the face 2|4 is substantially parallel with the link |60.

'I'he operation of the mechanism is essentially as follows, see especially Figs, 3 and 14 through At some given instant the cam roller 2|0 and cam |90 are in the relative positions illustrated in Fig. 14, the cam roller and its link |60 being in advanced or extreme rear position. 'Ihe roller is upon a straight front face 2|4 of a lobe,

which face is generally parallel with the link |60 and hence the link is supported in a lowered position, free from engagement with the list holder. The link |66 now retracts or moves towards the front of the machine and the cam also moves in the same direction until both are in the position of Fig. 15, the roller and cam maintaining their relative positions but the roller and link being somewhat elevated and the high part of the lobe 2|2 being in the path of rearward movement of the roller. The link |60 now moves rearwardly. Since the cam is held stationary the roller climbs the cam lobe and hence the latch |16 of the link is elevated and caused to engage the list holder and advance it one line, the final advanced position of the link being such that the roller is on the tip of the lobe, as in Fig. 16. The link |60 now again moves toward the front of the machine, the cam also advancing and in such manner that the roller 2|0 stays on the tip of the lobe to the end of the stroke of link and cam, as

in Fig. 17. The latch |16 yields and drags over the teeth |80 of the list holder without moving the holder. The link |60 is then moved rearwardly while the cam is held stationary. During the initial part of such movement the roller drops off the tip of the lobe into the position of Fig. 18 before the lost motion between the latch block |66 and link |60 has been taken up and hence the link is free to move further or into the dotted position of the roller or into the initial position of Fig. 14 to begin a new cycle.

It is desired to compile the lists from the data carried by selected stencils only of the collection. Hence selector mechanism is employed to condition the printing mechanism to operate only upon selected stencils and to effect the passage of unwanted stencils through the printing position without printing therefrom. Heretofore the selectormechaism has been operated to feel a stencil at every printing operation. With the present machine, however, the feeling of a stencil at every printing operation would result in an improper operation of the machine. For instance, if a selected stencil was in printing position and the next adjacent stencil which is felt by the selector happens to be one that is not desired to be printed thereform the selector mechanism would operate to disable the printing mechanism following the rst printing operation on the stencil that is in printing position and would effect the movement of such stencil out of printing position. Thus only one of the desired two impressions from the same stencil would be made. Hence the selector mechanism is so arranged as to feel a stencil only during alternate cycles of operation of the printing mechanism.

The selector mechanism, see Figs. 1, 2, 5, 6 and 7, includes a selector frame 2|6 horizontally disposed above the stencil track adjacent the printing head and movable vertically toward and away from that stencil that is in the stencil track next to the one in printing position. Said frame has a vertical guide member 2|8 slidable in a guideway 220 carried by a bracket 222. The selector frame 2|6 has a plurality of pin receiving holes 224 into selected ones of which resiliently mounted. feeler pins 226 are adapted to be positioned, the position of the pins corresponding to the position of the selector perforations 36 of the stencil of Fig. 20. The arrangement is such that if a pin can enter a selector perforation during the descending .movement of the selector frame and electrically engage a stencil rail an electric circuit is completed'which either conditions the printing mechanism for a printing operation upon that stencil or disables the printing mechanism so that the stencil can pass through the printing position without being printed from, as may be desired. The vertical guide 2|8 of the stencil frame is provided with rack teeth 228 which mesh with a gear sector 230 fixed to a horizontal shaft 232 that is oscillated to effect the reciprocation of the stencil frame. The oscillation of said shaft is effected through an upstanding arm 234 that is fixed to the end of the shaft and is connected through a link 236 with the end of an upstanding arm 238 fixed to the shaft 240 at one end thereof. Said shaft at the other end has an upstanding arm 242 which is connected through a link 244 with the arm 246 of a shaft 248 located at the rear of the table 38 and cam roller 252 that engages the cam face 254 of the sector 96. The arrangement is such that on the latter portion of the upward movement of the sector the roller 252 passes along the inclined lower cam face 256 of the cam and hence the lever and the shaft 248 are moved in a counterclockwise direction under urge of a spring 258 connected to the arm 256. This movement of the shaft takes place during the latter part of the printing operation and effects the downward movement of the selector frame into stencil feeling position.

The completion of an electric circuit through a stencil energizes an electromagnet 266, see especially Fig. 5, located at the rear of the machine which magnet pulls down one end of a lever 262 that is pivoted intermediate its ends, and raises the other end thereof to effect the raising of a latch 264-, see especially Fig. 4, loosely pivoted on the shaft 248. The latch 264 is in control of a lever 266 pivoted intermediate its ends at 268 and having a lower end 216 disposed in position to engage the roller 212 of the latch 92 that controls the connection between the operating sector 96 and the operating arm 36 of the printing mechanism. A tensile spring 213 is connected with said lever 266 to bias the lever 266 for movement in a clockwise direction. The upper end of the lever is provided with a pair of vertically spaced

detents

216 and 218 and the latch 264 is provided with a reversible hook member 286 disposed between the detents and adapted in the position shown to engage the lower detent 216 and in the reversed position to engage the detent 219. In the position shown the arrangement is such that a printing operation is eifected when a circuit is completed through a stencil. In the reverse position of the hook 286 the opposite is the case. Thus with the arrangement shown the lever 266 is normally engaged with the latch 264 and the lower end of the lever is held in engagement with the latch 92 so that the printing mechanism is normally disabled. When, however, a desired stencil comes into selecting position the latch 264 is disconnected from the lever 266 thereby to release the latch 92 and to connect the operating arm 86 and the sector 96 to effect a printing operation. y

The lever 266 is restored into engagement with the latch 264 during a part of every printing operation by means of a cam block 262 carried by the operating sector 96 and engaging a roller 284 of the lever 266 to rotate said lever in a counterclockwise and resetting direction. Thus after every printing cycle the lever 266 is reset, with the mechanism so far explained, to disconnect the operating mechanism from the operating sector 96.

With this method of operation only one impression would be made of the saine stencil. Hence mechanism is provided to modify the above described manner of operation in such a way that the operating arm 86 and sector 96 when once engaged stay engaged for two complete printing operations. Said mechanism, see Figs. 4 and 5, includes a cam disc 266, a brake or retaining drum 268 and a ratchet wheel 296, al1 pinned or otherwise secured together forl conjoint rotation and rotatably mounted upon a stud shaft carried by a bracket 262 iixed to and extending from the rear of the table. The cam disc 266 is disposed beside and under the latch 264 and the latch has a depending projection 294 that rides upon the cam disc. The cam discV has a plurality of lobes 296 that successively engage and raise the latch 264. The

arrangement is such that when a lobe 296 is under the latch projection 294 the latch is supported in an elevated position and thus is disengaged from the tripping lever 266 for the latch 92. When the projection 294 is in the valley between two lobes the latch 264 is free to move downwardly and thereby to engage and lock the tripping lever 266 in a position where it holds the latch 92, disengaged from lthe operating sector 96.

The cam disc is rotated intermittently in a step by step manner, each step being one-half the distance between two consecutive lobes so that a lobe and then a valley are positioned successively under the projection 294 of the latch 264. With this arrangement the latch 264 is held in elevated position during every alternate printing cycle sc that it can not engage the tripping lever 266 and hold it in a. position to hold out the latch 92. Thus two printing operations are effected on any one stencil for one feeling operation thereof.

The cam disc 286 is held releasably in any advanced position by a resilient retaining strip 298, the relexed end of which enters the successive notches of the brake disc 286. The cam disc is advanced in a step by step manner by an arm 366 pivoted concentrically with the cam disc and having a pawl 362 that engages the successive teeth of the ratchet disc 296. 366 is reciprocated by means of a lever 364 connected with the operating arm 86 of the printing mechanism by means of a pin 366 carried by said arm and operating in a longitudinally eX- tended slot 368 of the link 364. With this arrangement the arm 366 is moved during the upper and lower parts only of the stroke of the arm 86.

Since two printing operations are made upon the same stencil it follows that the selector frame must be disabled during every alternate printing operation and that the stencil advancing mechanism must also be disabled for alternate printing operations. The mechanism for effecting these results will'now be explained with reference to Figs. l, 2, 6 and 7. The stencil advancing mechanism includes a pusher 3|6 which advances the successive lowermost stencils from the stack into and along the stencil track. The pusher is reciprocated by means of a connecting rod 3i2 which is located under the table 38 and is pivotally connected to the forwardly extended arm 3M, see Fig. 2, of a bell crank having a vertical hub 3I6 pivoted to the table and having a right angularly related arm 3|8, the end of which operates in a cam slot 326, see Fig. 4, of the operating sector 96. The cam slot 326 is so shaped as to eiect a complete reciprocation of the pusher for each complete reciprocation of the sector 96. The connection between the pusher and the connecting rod 3I2 is by means of a pin 322, see Fig. 7, connected with the pusher and operating in a longtudinally extended slot 324 of the connecting rod, which slot at the extreme end thereof has a lateral extension 326. When the pin 322 is in said extension the pusher and connecting rod are operatively connected for conjoint reciprocation. When, however, the link 3|2 is moved toward the left, Fig. 7, so as to position the pin 322 in line with the slot 324, the connecting rod is free for reciprocation without corresponding movement of the pusher.

The control of the connection between the connecting rod and the pusher is effected through cam mechanism generally similar to the cam The arm '.7'

Cil

mechanisms heretofore described. Said cam mechanism includes a multi-lobed cam disc 328, a brake disc 338, and a ratchet disc 332 pinned or otherwise secured together for conjoint rotation in the order named, and fixed to a vertical shaft 334 journalled in a bracket 336 carried by the table 38 beside the connecting rod 3 I2. A swinging arm 338 is pivoted on the Ybracket 336 and is located between the connecting rod 3I2 and the cam disc 328. Said link at its free end has on one side thereof a roller 348 that is engaged with the connecting rod and on its other side a roller 342 that is engaged with the cam disc 328. A tensile spring 344, see Fig. 2, serves to hold the connecting rod against the cam roller 340 and the cam roller 342 against the cam disc 328. The arrangement is such that when a depression or valley between two consecutive cam lobes 348 of the cam disc confronts the roller 342 the pusher p'n 322 is located in the lateral extension of the slot 324 of the connecting rod and the pusher is thus arranged for operation. So long as the valley between two lobes confronts the roller, the pusher is conditioned to advance a stencil for each stroke or cycle of the operating sector 96. When, however, a lobe of the cam disc confronts the roller 342 the link 3l2 will have been moved laterally to position the slot 324 of the connecing rod in line with the pin soV that the pusher and connecting rod will be disengaged and no stencils will be advanced, regardless of the number of strokes of the operating sector 96.

The advance of the cam disc is accomplished by the operating sector but only as determined by the selector mechanism; The camdisc is advanced progressively in an intermittent manner by means including an arm 348 pivoted on the rotatable cam shaft 334 and having a pawl 350 engageable with the teeth of the ratchet disc 332. Said arm 348 is reciprocated through a connecting rod 352, see Figs. 2 and '1, pivotally connected to the forwardly extended arm 3l4 of the pusher operating bell crank lever. The` free end of the rod is provided with a longitudinal slot 354 therein having at one end a lateral extension 356 in which slot and extension a pin 358 of the arm 348 can operate. A tensile spring 368 is connected with said connecting rod 352 and normally urges the connecting rod for lateral displacement into a position where the pin 358 is disposed in the slot 354 and thus the connecting rod and arm are operatively disengaged. When, however, the connecting rod is moved into the position indicated in Fig. '7 against the bias of the spring 368 the pin 358 is disposed inthe lateral extension 356 of the slotk and thus the arm and connecting rod are operatively engaged to effect progressive advancement of the aforesaid cam disc.

The purpose of this arrangement is to speed up the operation of the machine when stencils are passed through printing position without being printed upon. The normal arrangement is such that when a stencil is to be printed from, the stencils are advanced every second cycle of the machine. When, however, the selector mech- -anism finds an unwanted stencil it is desirable to move that stencil through the printing position as rapidly as possible and hence the stencil advancing mechanism is conditioned to advance a Vstencil at each cycle of the machine until the selector mechanism finds another stencil to be used for printing whereupon the stencil advancing mechanism is again set to advance a stencil every second cycle.

The mechanism by which this result is obtained and the connection between the connecting rod 352 andY the arm 348 is controlled includes a link 362 having a roller 354 at its forward end which engages the forwardlong edge of the connecting rod 352. The rear end of said link is pivotally connected to an upstanding arm 386 of the shaft 288, see also Figs. 4 and 5, to which the tripping lever 266 is xed. With this arrangement when the tripping lever 268 is in the position illustrated in Fig. 4 and thus is in a position to effect a printingoperation of the printing mechanism upon a selected stencil, the connecting rod 352 is held by the spring 216 of the tripping lever in engagement with the arm 348 and thus the pusher is arranged to operate every other cycle of the machine. When, however, the tripping lever 256 is held in latched position by the latch 264, which is the normal position except when a stencil has been selected for printing, the connecting rod 352 is free for movement into a disengaged position with respect to the arm 348 and the pusher is thus conditioned to be operated every cycle of the machine, the disconnection position of the connecting rod 352 and arm 348 being such that the pusher controlling cam disc 328 is left in such position that one of the valleys between the lobes confronts the roll 342.

It has been previously stated that mechanism is provided to prevent the selector from feeling f a stencil except during alternate printing operations. The mechanism is further so arranged that it feels every stencil. Thus if there are a succession of unwanted stencils advanced along the stencil track and one stencil is advanced every cycle of the machine theselector is arranged to feel each stencil and thus makes one operation for every cycle of the machine. When,

however, the selector finds a stencil that is to be printed from, the selector is arranged to be disabled for the next cycle. The mechanism for accomplishing this result includes a cam disc 368 fixed to the aforesaid shaft 334 that carries the pusher controlling cam disc 322. Said cam disc 368 is located above the table 38 and has as many lobes 318 as there are lobes on the cam disc 328, the lobes of both discs being in line. A link 31| is pivoted at its rear end to the upwardly extended arm 312 of the shaft 248 that reciprocates with the selector frame 2I6. The forward end of said link has a cam roll 314 that confronts the cam disc 368 and is movable toward and away from said disc and into and out of engage- Y ment therewith. Said cam disc 368V and roll 314 control the descending or operative movement i of the selector frame, which movement is underV urge of the spring 258, see Fig. 4, when the arm 258 Vfixed to the shaft 248 is freed for movement by the position assumed by the cam 254 of the operating sector 96. Thus when a lobe of the locking cam 368 confronts the roller 314 the selector frame is held from moving suiiiciently downward for a selector pin 226 thereof to engage a stencil. When, however, a valley between two lobes of said cam disc confront the roller 314Y the selector frame is free to descend into operative feeling relation with a stencil. The locking cam 368 is rotatable with the pusher controlling cam 328 and is so arranged that the selector frame is free to feel a stencilat the same operated to feel a stencil during each cycle but when the pusher is disabled the selector mechanism also will be disabled and thus will feel only once of each stencil selected for printing notwithstanding that two cycles of operation of the machine take place to effect the dual printing of the stencil.

While the machine has herein been described for making a dual impression of selected stencils it will be apparent to those skilled in the art that triple or more impressions can be provided by a proper arrangement and control of the various control cam discs without further showing.
