This invention relates to stencil printing or adressing machines.

One of the objects of the present invention is an improved machine for automatically addressing envelopes. V

In an envelope addressing machine of the character of the present invention the stencils or address bearing devices are moved from a holder through printing position and fall into a receiver. The envelopes are moved from a holder into and out of printing position and fall into a receiver. The location of the stencil and envelope holders and receivers is a matter of considerable importance in providing a well appearing machine having simple and accessible parts and arranged wherein the printing operaticn can be watched; and in the present invention the stencil and envelope holders are arranged at opposite ends of the machine while the stencil and envelope receivers are located at the opposite sides of the machine, with the stencils and envelopes moving in the opposite direction into a common'printing positionand thence moving at right angles to theirprevious line of movement into their respective're'ceivers. Such an arrangement constitutes a further object of the invention. g

It is quite common to utilize only a portion of the total number of addresses of a stencil collection and it is an object of the present invention to provide improved mechanism for effecting the printing of selected addresses only on the envelopes and to move envelopes into printing osition only in accordance with selected stencils.

The operation of the printing mechanism is controlled by selector mechanism governed by the stencils, the stencils controlling the completion of an electric circuit that governs the selector mechanism. For some purposes it is desirable to effect the operation of the printing mechanism when the electric circuit is made by the stencil and at other times to interrupt the printing operation when the. circuit is interrupted by the stencil. It is an objectof the present inven tion to provide a selector mechanism which not only controls the operation of the printing mecharsm but also of the envelope feeding mechanism and that can be conditioned readily to operate as desired under both conditions.

A further object is generally to improve the construction and operation of addressingv machines.

The machine embodying the present invention comprises ahorizontal table 20 supported at the top of a base or frame 22. A holder 24 for a vertical stack of stencils 26 is located at one end of said table and extends upwardly thereabove. The successive lowermost stencils of the stack are moved from the stack by means of a reciprocatorypusher 28 of more or less usual construction and operated in more or less the usual manner into and along the rails 30 and 32 of a track which extends horizontally in spaced relation above the table toward the other end thereof and connects with other and right angularly disposed rails 30a and 320. which extend to the rear of the machine and guide the stencils into a position Where they 55 fall from the rails of the track into a stencil receiver 34 located beneath the track. The stencils are or may be rectangular in shape, as illustrated in Fig. 17, and are moved in the direction of their length along the rails 30 and 32 into and out of a printing position and thence in the direction of their width along the rails 30a and 32a into the stencil receiver.

The pusher 28 is reciprocated to move the stencils from the holder into the track by means of a link 38 which is located under the table 20 and is pivoted at one end to the pusher and at the other end to an arm 38 of a vertical hub 40 which is oscillable on a vertical stud 42, see Figs. 1 and 3. tended arm 44 that is located in a cam slot 46 formed in the upper extension of an arm 48 that is pivoted to a bracket 50 securedto the table 20. The shape of the cam groove is such that when said arm 48 is moved from a raised position into the lowered positionshown in Fig. 3, a stencil is caused to be moved from the holder into and along the track. The arm 48 is actuated in more or less the usual manner by a reciprocating connecting rod 52 from a power mechanism 54 that is now well known in the art, which mechanism has a shaft 58 that is driven continuously by means including the pulley 58.

The stencils are advanced in a step by'step manner through the printing position and thence into the wide portion of the stencil track or into the rails 30a, 32a. Separate mechanism is employed to move the stencils in a step by step manner along the wide portion of the track and into the stencil receiver. Said mechanism, illustrated more particularly in Figs. 2 and '7 through 10, includes a reciprocatory slide 60 which is horizontally slidable in astationary guide member 82 that is disposed above the rail 30a. Said slide carries a bracket64 which extends over the wide portion of the track and has a shaft 60 journalled therein that supports a finger frame 68 having forwardly directed fingers I0. Said frame can be lowered into position to engage the forward wide edge of the stencil and thereby move the stencil rearwardly along the wide track. The finger frame can also be moved to an elevated position to be free from engagement with the stencils at the time'the slide 80 moves forwardly. It will be understood that in the present machine a stencil is advanced along the track at each cycle of operation of the machine and hence the fingers I0 are adapted to be in lowered position and to engage a stencil and move thestencil rearwardly at each rearward stroke of the finger frame. The

finger frame has a rearwardly extended arm I2 that is connected with a tensile spring. I4 that tends to rotate the arm in a counterclockwise direction to bring the fingers 70 in a lowered position to engage the stencils. The fingers I0 are raised and lowered by means including a bar I6 which is extended horizontally over the frame parallel with the wide portion of the stencil track. The finger frame has an upwardly extended arm -18 that carries a roller that rides upon the upper face of saidbar. Said bar is secured 'toa frame 82; see especially Figs. 2 and-4, that is horizontally pivoted to a bracket 8-4 fixed to the left hand portion of the table. The bracket is raised and lowered in timed relation to the movement of stencils, not only for the purpose of controlling the positions of the fingers I0 but also for effecting the positioning of the envelopes into printing position, as will presently appear. by means including a shaft 86, see Figs. 1, 2, 4 and Said hub 40 has a laterally ex-- 5. Said shaft is journalled in brackets 88 and 90 beneath and transversely of the table and is rotated in timed relation to the stencil movements. Said shaft at its forward end is provided with a cam 92 which engages a roller 94 of an arm 98 that is secured to the frame 82. The shape of the cam and its relation with the roller 94 is such that it causes said frame 82 and consequently the bar I8 to be lowered at the time the fingers 10 are above and forward of the front edge of the stencil. The slide 60 that reciprocates the fingers I0 is also reciprocated'in timed relation to the stencil movement in such manner as to bring the fingers into position in front of the successive stencils in the wide portion of the track at the time the line of stencils in the narrow portion of the'track isstationary and to move the stencils outof the line of movement of the stencils in the narrow portion 'of the track before said stencils are advanced. This movement of the stencils in the wide portion of the track is carried out at the time an envelope is being moved into printing position.

The reciprocating mechanism for the slide E0 includes a link 98 which is pivoted at its front end to the slide and at its rear end to the upper end of a lever I 00, which extends downwardly over the left hand end of the table and is pivoted on a pin I02 to the frame 22. The lower end of the lever is connectedby means of a connecting rod I04 to a crank arm I08 fixed to a'shaft I08. Said shaft is journalled in an arnr IEO of the aforesaid bracket 90 at right angles to the shaft 86 and drives said shaft by means of the miter gears H2. The shaft I08 is driven through a sprocket H4 and a chain I I6, see especially Figs. 1 and 5, from a shaft II8 which isconnected through reduction gearing I20 with the shaft 58. The arrangement is such that the shafts 8B and I08 make one complete revolution for each cycle 2 of operation of the machine.

tencil printing mechanism is located at the printing position and-is illustrated particularly in Figs. 1, 2 and 3. Said mechanism includes a printing-roll I22 which is rotatably mounted be:

tween the forked arms I24 of a bell crank lever I26 that is pivoted on a shaft I28 carried by the bracket 50. Said bell crank lever has a downwardly depending arm I30 that is pivotally connected through a link I32 to an arm I34 that is pivoted at I36 to the bracket 50 concentrically with the actuating arm 48. A platen 138 carried by a pivoted frame I40 beneath .the printing roll I22 and the stencil track and is movable upwardly tohold an envelope disposed beneath the 1 1' track into position to be engaged by a stencil therein. The platen is reciprocated by a cam arm I42 which is fixed to the arm I3 4. The arrange ment is such that when said arm I34 is moved upwards in a counterclockwise direction, the platen and printing roll I22 are moved toward each other. v

The arm I 34 is at times adapted to be connected with and at other times disconnected from the actuating arm 48 depending upon whether or not it is desired to print from the stencil that is the next to be moved into printing position. end the arm I34 has a latch member I44 pivoted thereto and extended upwardly thereabove. The

latch member has a detent I46 that is adapted to .1

enter a recess I48 of the arm 48 whereby to establish an operative connection between said arms 40 and I34. A spring I50 serves to urge the latch member I44 into position for engagement with the arm 48. Selector mechanism presently to be de- To this scribed isprovided to: control thev position. of the latch and to determine. whether ornot the printing mechanism is to be reciprocated after certain stencils have been'moved into printing position.

The printing roll M22 is supplied. with inkv in more or less the usual manner by mechanism I5! not herein necessary to describe;

The envelopes that are adapted to be addressed by the present machine are'contained in a verticalstack l 52,, see Fig. 1,.in an envelope holder I54; Said envelope. holder isdisposedatitheleft hand end of the table in line with the narrow portion of the stencil track and comprises an upstanding front plate 56 and an opposed upstanding rear plate I58. The front plate I55 is provided with a horizontal-ear ltfi at the bottom thereof which slides upon a ledge I62 of the. table so that the plate can be moved forwardly and backwardly to adjust the holder for various sizes of envelopes. The rear plate l58 is similarly providedv witha horizontal ear i ii that overlies andrides upon the ear 1%. The cars are longitudinally slotted and a screw U56 passes through the slots in said ears and into the ledge 562 whereby to secure the plates releasably in adjusted position. A horizontal rod 162? extends loosely through the side plates above the bottom thereof and is adapted to support the stack of envelopes in an inciined position so that the frontedges thereof are against a va'tical guide plate Ht. Said plates 56 and I58 are provided with parallel forward extensions H2 and 114 which constitute tracks along which the envelope is guided into printing position, the track l'i' i being behind the printing roll and being longer than the track H2. The envelopes are moved into printing position and against an adjustable stop member H73. Said stop member has an arm $18 loosely pivoted thereto at the rear end-and. adapted to bear by its weight against the successive envelopes as they are being moved forwardly out of printing position for the purpose of preventing the edge of theenvelope that is adjacent the stop from moving" upwardly as the envelope is ejected. The forward-edge of the stack of envelopes rests upon-a feed roll 98%, see more particularly Figs. 1, 2; 4, 5 and 6; Saidfeed roll is loosely mounted upon the shaft 65 and the upperflpcrtion of its periphery extends through an opening in the table Ziland into the lower portion of the envelope'holder. A portion of the periphery of. the feed roll or drum is'occupied by a pair'of opposed corrugated rubber bands i8! which are secured to the at the opposite edges. thereof. The remaining peripheral portion of the'dr-um is smooth and is adapted to pass under the stack without withdrawing envelopes therefrom. The rubber hands when engaged with the stack of envelopes has sufiicient frictional en gag-ement therewith to move the successive lowermost envelopes out of'the stack and toward the printing position. The envelope feed drum is adapted to be stationary atthe time a stencil is passed through the printing position without printing therefrom. Hence the drum is provided with clutch mechanism for connecting it opera tiveiy with. the driving shaft 83. The clutch mechanism includes a disc wt that is fixed. to the shaft 86 and has a notch m8 in its periphery. The drum 189 has a latch arm 88 pivotedon a pin iQii fixed to the web of thedruin, the arm being urged by a spring I92 constantly toward engagement with the periphery of the disc 84. The latch arm has a detent I51 that can enter the notch #88 and therebyestablish driving connections between the drum and the shaft. When to prevent the feeding of an envelope.

theidetent 594 is out; of the notch the disc can rotate independently of. the drum and the-drum is, held stationary by a brake member I96. that frictionally. engagesthe periphery of the drum; The driving engagement between the arm I 88. a11d the disc it is controlled by mechanismwhich in turn is governed by: the stencils in such manner that a stencilwhich is, to be. passed through the printing position without being printed therefrom disengages the arm and disc so that the shaft 86' can rotate; whilethe drum is stationary and hence Said mechanism includes a clutch tripping rod Hi8 hieh is horizontally slidable in the bracket. 9.0. in one direction-toward the drum to position its .in;-

end between the disc 18d. and the latchzarm In this position the rotation. of. the drum and the arm causes a cam portion 28%? of the arm to ride over the end of the. pin I98 and thereby move "the latch arm outwardly to disengage it from the driving disc, 1M, whereupon thefeed drum becomes stationary. This-stationary position of the drum is illustrated in Fig. 4, where the ends of the envelope driving bands H82 are just in position to engage the lowermost envelope of the stack when the drum is again advanced. Therod let. is slidable in the opposite direction out of position between the latch arm I83 and the disc [86 whereby to permit the latch arm to move inwardly so. that the detent. I94 rides upon the periphery of the disc and ultimately drops into the notch i 88 thereof to establish the driving connection between the disc and the drum.

The movements of the rod 98 are controlled;

at will, by either one of independently operable clectrornagnets 2532 and 28 which are mounted upon .a bracket 2% securedv to the underside of the table at the rear portion thereof. An. armature 298 overlies both electromagnets andis pivotally mounted in between them, the armature being loose on a shaft 2H3 which is carried by a supporting structure 212. The armature has a bifurcated extension 2H5 at one end in which the notched portion 256 of the tripping rod I98 is loosely received. Movement of the armature in a counterclockwise direction serves to move the rod 198 into a clutch disengaged position and or holds the control circuit open, as desired. One

of the eleetromagnets, asthe electromagnet 204. is arrangc-id to establish connection between the driving shaft 36 and the envelope feed drum: iBil when the control circuit is completed whereby to permit. the feeding of the envelope into printing position. The other el-ectromagnet 202 is arranged to establish driving connections between the shaft and drum, and the consequentfeeding of an envelope when the control circuit is open andto break the driving connect-ion and prevent the feeding. of an envelope when the control circuit is closed. the purpose of selecting whichever electromagnet is desired for operating the armature Zi-ip Said mechanism. includes a hand operated armv 218 which is carried by the pivot shaft 2H3 and. located in a slot 22s of the armature. An overcent-er spring 222 is connected to the arm. M8 to holdqthe arm either in the position shown in Mechanism is provided for Fig. 12, 01' in a similar position on the otherside of the center of the shaft2I0, as desired. The

arm 2 I8 in the position shown in Fig. 12 engages one side wall of the slot 220 so that the spring 222 holds the armature against the electromagnet 204 and away from the electromagnet 202. Hence when the electromagnet 202 is energized the armature is attracted thereto against the pull of the spring and consequently moves the tripping rod I98 in a position to disengage the clutch mechanism and prevent the feeding of an envelope. When the electromagnet 202 is unenergized the clutch mechanism is engaged and the envelope feed drum rotates continuously with its drive shaft'86 so that successive envelopes are fed out of the envelope holder, the feeding of envelopes being interrupted only at times when the electromagnet 202 is energized. When the arm 2 I8 is in the opposite position the armature 208 is held against the electromagnet 202 and away from theelectromagnet 204. In this position the tripping rod I98 normally holds the clutch disengaged and the clutch is engaged only when the electromagnet 204 is energized.

The successive envelopes are not moved completely into printing position by the feed drum I80 but only sufficiently toward the printing position to be engaged by a pair of feed rolls 224 and 226, see especially Figs. 1, 2 and 4, which are disposed close to andin front of the outer rail of the narrow portion of the track, and which rolls advance the envelopes into the printing position. The lower feed roll 224 is an idler roll andis journalled in a bracket 228 that is secured to the underpart of the table and extends upwardly through an opening therein. The upper feed roll 226 is continuously driven and is fixed to a shaft 230 that is journalledin the aforesaid bracket 82. As has been previously described the bracket 82 is reciprocated in a vertical direction by the arm 96 and cam 92 for the purpose of controlling the movement of the stencils along the wide portion of the track. This reciprocatory movement of the frame 82 also moves the roll 226 toward and away from the idler roll 224 whereby to control the advancing of an envelope between said rolls. When said frame 82 is in a lowered position the roll 226 is in position to bear upon an envelope thereunder and to move the envelope into printing position. The movements of the frame 82 are so timed that envelopes are fed into printing position before the completion of the printing movement of the platen and printing roll. The feed roll 226 is adapted to have a greater peripheral speed than that of the feed drum I80 whereby to move the envelopes rapidly in printing position. The roll 226 is driven by suitable means as the chain 232 which is' passed over a sprocket 234 fixed to the shaft 236. The chain passes over an idler pulley 236 and also over a slack take-up roll 238 joumalled ona spring urged arm 240 and about a driving sprocket 242 that is fixed to a hub 244, see especially Fig. 5, that is loose on the shaft 86. The hub 244 has a pulley 246 fixed thereto which is driven by a belt 248 from a pulley250 fixed to the shaft 56. The roll 226 need not rotate in any timed relation with other elements of the machine so that the chain 232 can be replaced by a belt or other driving means if desired.

After the printing operation has been effected the envelope that is disposed in printing position is adapted to be removed or ejected therefrom toward the front of the machine along a line parallel with the guiding edge of the stop member I16. The ejector mechanism, see especially Figs. 1, 2 and 4, comprises a pair of continuously rotat ing feed rolls 252 which are disposed in front of the printing roll I22 and are fixed to a drive shaft 254 journalled in brackets 256 carried by the front track 32. Said shaft 254 is rotated continuously by a belt 258 that is passed over a pulley260 of said shaft and also over a pulley 262 of a jack shaft rotatably supported in the lower portion of the base of the machine and driven by a belt 264 from a second jack shaft 266 which in turn is driven through a belt268 from the shaft 56 of the power mechanism. The continuously rotating rolls 252 cooperate with a pair of idler rolls 210 that are loosely journalled in upstanding arms 212 of a slide 280, which slide is vertically reciprocable in a bracket 282, see especially Figs. 4, 15 and 16. Movements of the slide are controlled by a lever system including an arm 284 which is fixed to the inner end of the shaft 286 journalled in arms of the aforesaid bracket 228.v Said arm 284 overlies the rear face of the slide 280 and has a1ongitudinally elongated slot 288 therein in which a roller 290 of the slide 280 is located so that reciprocatory movement of said arm 284 in a vertical direction causes the raising and lowering of the slide. A spring 292 is connected with said arm 284 and serves to maintain the slide 280 yieldingly inun elevated position or in cooperative relation with the continuously rotating driving rolls 252. An arm 294 is fixed to the front end of the shaft 286 and has a cam roller 296 thereon which is in engagement with a cam 298 fixed to the drive shaft 86. The cam is so arranged as to effect the raising and lowering of the slide 280 at suitable periods. When theroller 296 is opposite the depressed portion 300 of the camthe spring 292 urges the slide upwardly and thereby presses any envelope that may be thereabove against the feed rolls 252 so that the addressed envelope is ejected forwardly out of printing position and, if desired, into a suitable receptacle 302 that lies mainly below the table. velopes is timed to take place after the platen and printing roll have released the envelope and prior to the movement of a new envelope in a printing position. i

It has been stated heretofore that selector mechanism controlled by the stencils is provided so that unwanted stencils,'that are automatically located, can pass through the machine without being printed therefrom. Said selector mechanism is illustrated particularly in Figs. 1, 2, 3 and 14. Said mechanism includes a selector frame 304which is disposed above and is reciprocable toward and away from the narrow portion of the track at one side of the printing position and is fixed to a shaft 306 journalled in a bracket 308 carried by and electrically insulated from the table. Said selector frame can carry one or more selector pins 3 I 0 which when the frame is lowered can make electrical contact with one or the other of the electrically grounded tracks 30, 32, if the stencils 26 have passages 3I2, see Fig. 17, therethrough that are aligned with one or more of the selector pins at the time the selector frame is, moved downwardly. The arrangement can be such as to effect; the printing of the stencil that permits a selector pin to move through a passage 3I2 and electrically engage the track; and it can also be such as to prevent the printing operation of the machine on the stencil that permits the electrical contact between a selector pin and the track. The selector mechanism, like the envelope feeding mechanism heretofore described, is caill cated bya link3l4 which "is pivotally connected to, but is electrically insulated from, an upstanding arm Silt of the shaft 336. Said link is also pivotally connected at its rear end to an upstanding arm 3. 8 of a shaft 320 which is journalled-in a bracket and has a depending arm 323 that extends through a passage in the table and terminates in a cam roller 326 that is disposed at one side of the upwardly extending projection 328 of the reciprocating arm 43, and is maintained in engagement with a cam face 333 of saidarm. Said cam face is so arranged that, at the upper portion of thestroke of said arm 43, the arm 324 is permitted to move ina counterclockwise direction whereby to move the selector frame downwardly to feel the stencil therebeneath and thereby determine whether or not a printing operation shall be effected on such stencil. The selector mechanism includes a frame 332 which is pivoted at to the bracket 322 and has a depending arm 336 provided with an extension 333 that overlies a roller Mil carried by the upper end of the latch arm I, which arm as has beenexplained, controls theconnection between the arm tiland the printing mechanism.- Said frame 332 is urged by a spring 342 for movementin a clockwise direction to permit the engagement of the latch arm M lwith the actuating arm 88. The frame 332 has an upwardly extended detent arm 333 that has opposed upper and lower detents 33.8 andt ill respectively that lie on opposite sides of a latch member 358. Said latch member 353 is carried reversibly by an arm 352 that is loose onthe shaft 322i]. When the latch member 353 is in the position shown it is capable of engagement with the upper detent 348 and in such position conditions the mechanism to effect a printing operation on a stencil that does not permit contact to be made between a selector pin and the track. When the latch member 359 is inverted and is in position to engage the lower detent 348 the arrangement is such that a printing operation is effected on the stencil that. permits contact to be made between a selector pin and the track. Vv'hen the latch member is free from the upper detent 348 it can drop. a

The latch member is raised and lowered by means of a lever 354 which is pivoted intermediate its ends at 353 to the bracket 322 and one end of which lies beneath the latch member 35t'and the other end of which carries an armature 358. Said armature is moved downwardly into attracted positionby an electromagnet 35 t whereby to elevate the latch 355i; and the armature moves upwardly into released position by the weight of the other end of the lever. The electromagnet 35D is in the circuit of the track and the selector pi so that it is energizedwhen connection is established between a pin and the track. The electromagnets "26-2 and 204 that control the operation of the envelope feeding mechanism can be connected inseries with the selector pin circuit but preferably are controlled through a separate circuit by the energization of the electromagnet 330, which magnet acts as a relay for the circuit of the envelope feed control magnets. .To this end the armature 353 carries an insulated movable contact member 332-which cooperates with the insulated stationary contact membertiit that is in the circuit of the aforesaid magnets. The'circuit'connections are illustrated inFig. ,13 andneed not be explained in detail.

Current for actuating the electromagnets can be derived from any source as the transformer .365. A double throw switch 353 is provided forselectively and separately connecting the electromagnets 202 and 2Mv in .th'eircontrol circuit.

The frame 333 is provided with a forwardly di- 1 rected arm 3W that hasalatch roller .312 thereon that cooperates .with'a cam face 3'24 of the actuat :ing armilt... Whensaid arm is moving upwardly the cam face causes the irame 332 to move in a counterclockwise direction so that-the. detent t lt :is disengaged from the. latch Imember .359 which then can. drop if the electromagnet 3.631s notenergized. vIf this is the case, whenthe arm 25 moves downwardly so that the cam 3' moves away from the roller 3ft 2 the spring 3.42 willithen move-the frame in a clockwise direction; away from the latch arm: its so that':said latch, arm can engage the actuating v'armbil, and, on the nextupwardistroke of said arm, erl ectthe printingoperation. Thecam 3Y4 rotates the frame 332 in a counterclockwise direction, or into a position where the latch member M4 is disengaged, at each. upward stroke of the arm ,48, and .the latch member 3551 in, the electromagnet deter: mines whether or not theuframe will .be held in such position to hold the latch member 14.4 out of engagement. cams 3,33 and 31.4 is such that the selector frame is in lowered position and hence acontact is made if one is toibe made and the electromagnet 360 is energized at the time the cam- 31.4 is .passingout from under the roller 3,72 and permitting the frame 332 to move in a. clockwise direction. ,If the circuit is closed and-themagnet isenergized ieue t ste ci he c mm ene 3138 wi not 1 be J energized and the latch member. 350 will notbe raised and hence the frame 332 is free to m e a clockwise d e t o and .pe mittbe engagement of the latchmember i 44 andthereby 5.
