PRINTING- MECHANISM Specification of Letters Patent.

Patented July 30, 1907.

Application filed April 14,1906. Serial No. 311,645.

To all 'whom it may concern:

Beit known that I, FREDERICK Cr. JAHN, a citizen of the United States, residing at the borough of Brooklyn, city and State of New York, have invented certain new and useful improvements in Printing Mechanism, of which the following is a specification.

The present invention relates generally to that class of machines wherein someinstrumentality thereof is Operable only by reason of the presence of the article being handled or Operated on, for such purpose, for instance as printing, marking, counting or registering vsuch article.

It has for its object, among other things, to provide a simple and efficient feed mechanism by which the accurate feed of individual pieces from a stack, bunch or pile of such pieces is insured; to provide an automatic mechanism having a wider range of application both as to size and texture of the article, sheet or other matter capable of being handled thereby, and, when employed in a printing or marking machine as to the variability in the location of the impression that may be applied to such article than was possible in machines heretofore in use; and -furthermore to improve and simplify the construction and operation of such mechanism to the end that unskilled persons may run and Operate the same with little or no instruction.

The improvements are embodied in a machine which consists generally Of a feed mechanism by which the pieces of material or articles to be handled are separated one by one from a bunch, stack or collection of the same and carried singly forward for subsequent operation, and with which is associated an instrumentality, such as a printing couple or a counting device or both,

` the active function or operation of which is dependent upon the prcs-ence'of the piece or article with which it, or they are designed to coperate.

In the machine illustrated, the article such as a sheet or slip of paper, which is often of fi-imsy or light texture, instead of bearing the burden, as heretofore, of directly bringing about the active function of the operating instrumentality thereof, is utilized simply to set a function-controlling device in condition so that its subsequent or further movement which results in the operation of said instrumentality, is brought about by the act of the machine itself. In consequence of the article merely serving to set a device in condition for subsequent automatic operation, such operation may actually take place at any time early or later in the ma- As a better understanding of the invention Wili-.be 1

had from a detailed description of the improv,

chine such description will now be given, reference being had to the accompanying drawings, in which:

Figure l,is a side elevation. Fig. 2, is a plan View, the gear casing being removed. Fig. 3, is an end elevation, the gear c; ing being in section. Fig. 4, is a partial vertical transverse section taken on the line 4, of Fig. 1. Figs. 5 and 6 are horizontal sections taken respectively on approximatelylines 5 and 6, of Fig. 1, some of the parts being omitted and others broken away. Fig. 7, is avertical transverse section taken on the line 7, of Fig. 1, the counting device and its connections being added. Figs. 8 and 9 are diagrammatic sections taken on the line 8 of Fig. 4, of a portion of the feed mechanism, showing different positions of the feed controlling cylinder. Fig. 10 is a diagrammatic eleva tion of the operative parts of the machine, certain of the parts being in their moved positions; and Fig. 11 vis a similar view of a portion of said parts showing them in ak changed position. Figs. 12 and 13 are detail sectional closed elsewhere.

Referring to said drawings: a' pair of side frames 100,

101, united by suitable tie-bars a and carried by a base 1 02 aford'widely separated bearings for the spindles of the -main operating parts of the machine. The space between the side frames is occupied by the transmitting gearing which may be covered by a surrounding casing b; while those parts of the machine which actually engage the article, such as a sheet or slip of paper or other material being handled or operated upon, are carried `by the overhanging ends of the spindles which project laterally outward from the inner side frame 101 with no outer support therefor that would otherwise restrict the use of the machine to articles of less than a given width.

The operating parts of the machine consist in the main of a feeding mechanism A; a printing, couple or other suitable -instrumentality B, and, preferably, a stacker or receptacle Cfor the orderly collection of the articles handled by the machine. And they may also consist of a counting or registering device D, either in addition to the printing couple B or for use `in lieu thereof.

Specificially considered, the improved feeding mechanism A is composedz of one or more endless carrying bands 21 stretched around distantgrooved rollers 22, 24 which thus present a horizontal supporting and ear rying surface for the articles to be operated upon. Interposed in the active carrying portions of the endless bands, between the rollers 22, 24, is mounted a grooved feed controlling cylinder 20, the groove or grooves of which are shaped to permit the non-grooved portion Of th'e cylinder to project at times above the surface of the band or bands so that their carrying function is noneffective and at other times to permit the surface of the band or bands to project above the cylinder so that `their carrying function isrendered effective, thereby obtaining an intermittent feeding movement with a continuously rotating instrumentality. As shown in Figs. 1, 8 and 9 the carrying band groove 3 of the cylinder 20, for the major portion of its circumferential extent is deep enough to permit the non-grooved portion of the cylinder to project above the surface of the carrying band, the remaining portion 4, of the groove being made shallow or less deep so that the surfaceof the carrying band is projected thereby above the cylinder with the result that when the deep portion 3 of the cylinder groove is passing a given point, s uch as the opposed surface 25, as in Fig. S, no feeding movement' will be imparted and when the shallow portion 4 of said groove is passing said point, as in Fig. 9, an effectivefeed will take place. The non-grooved portion of the cylinder 20, coincident with the shallow portion 4 of the groove may be cut away or depressed as at 2, to lessen the needed projection of the carrying bands at their effective feeding point. Where the feeding mechanism is required to feed sheets or slips shorter than one half the circumferential length of the feed cylinder 20, two or more such shallow band-projecting portions 4 may be provided so that instead of causing the feed of one sheet or slip at each rotation of the cylinder, two

or more such sheets may be fed at each rotation thereof.A

A number of narrow carrying bands 21, in lieu of a single wide band, is preferably employed and the feed cylinder 20, is consequently formed with alternate rings and grooves, as shown in Fig. 4; and there is provided an idler roller 23 to sustain the carrying bands in their horizontal position under the Weight of the bunch or stack of articles resting on them in position to be fed through the machine.

All of the bands 21 need not pass to and around the roller 24, but one or more, such as the outermost one, may pass around the feed cylinder 20, as shown in Fig. 2.

The horizontal supporting surface of the bands may.

be extended by a table plate 30, that is supported from the side frame 101, or by an idle roller 31, as indicated by dotted lines in Fig. 1. I

With the feeding mechanism there is associated an opposed surface or separator in the form of a flexible wiper 25, with its free forward end resting upon and in some instances bearing with more or less pressure on the feed cylinder andserving to prevent the feed of more than one article at a time and coacting with the effective portion of the feed cylinder to permit the feed of single articles at a time, and only at predeter- -mined moments. The wiper 25 is a narrow flexible rubber strip removably clamped between the foot of its holder 26 and a clamping piece 28 carried thereby, The holder is removably and adjustably secured by screws 27 to the side frame 101 and supports the wiper in a fixed position over the feed controlling cylinder 2O so that a wedged shaped entrance or throat is formed for the leading ends of the articles in position to be fed through the machine. The wiper rubber is preferably formed with a canvas backing to prevent its stretching, and to impart increased elasticity thereto may be reinforced by vone or more flat steel springs 1, Fig. 2.

There is preferably associated with the carrying bands 21 an upper set of bands 32 that are stretched around grooved rollers 33, 34 and coaet with the under set of bands 21 in carrying `between theml the article forward through the machine. The two sets of bands ferm upper and under, traveling supports for the sheet or slip holding it closely confined between them and preventing its becoming crumpled or displaced when causing the operation of the controlling or setting device which governs the operation of the succeeding and normally inactive instrumentality of the machine to be presently described.

The mechanism to which the articles are advanced by the feeding mechanism is represented in the present instance b y the printing couple B which consists of an intermittently operable printing or marking surface or roller 35 carried by a driven spindle 51, and an impression surface or roller 3G, between which the articles handled by the machine pass. The impression roller like the feeding instruinentalities constantly rotate while the printing roller and its spindle rotate aceording as the controlling device is set to cause or permit its effective movement.

The surface of the printing roller is inked by a felt roller 37, carried by a stud projecting froma bar 3S that is adjustably and removably held in place by a clamp nut 39. To aid in 'keeping the surface of the inking felt roller smooth and free from ridges it may be in surface contact with a positively driven metal roller 40 which constantly rotates the felt roller and thus relieves the printing roller of that duty.

The space between the bight of the carrying bands and the impression roller is preferably bridged by lower and upper guides 41, 42 to guard and direct the may be associated with the bottom rods to aid in properly collecting the delivered articles. The receptacle may be provided With one or more overlying rods 45 adjustably carried by a transverse bar 4G projecting from the side frame to guide the articles from the printing couple into the receptacle and prevent their following around with the printing roller;

The mechanism for bringing about the 'timely operation of the normally inactive instrumentality of the machine, such as the driven spindle 51 of the printing couple B, or ofthe counting device D, or both, consists in the main of a controller e, which in the present embodiment normally holds the driven spindle against 'movement and whichv controller in itself normal-ly occupies a non-operable position; an article-operated device c, for. setting the controller in operable position and a power actuated device d, for moving the controller.

The controller a, has afi independently movable member f, which may be set into operable position by the action of the setting device c, as each article is presented thereto, so that the actuating device or stud d, will in its rotation engage the movable member f, and thus impart the necessary movement to the controller to cause or permit the effective operation of the driven spindle and consequentlyof the printing couple or counting device orboth.

The setting device c consists of a finger depending from a rock-spindle 6 across or into the path traversed by the article being handled by the machine and in the present instance lies in the space between contiguous bands of each set of carrying ban'ds 2l, 32, to be rocked forwardly during the onward movement of said article. The spindle 6 carries an arm that is connected to one end of a link 7 whose lower slotted end engages a rock arm 8 fast to a rock shaft 50, to the outer end of which is affixed the movable member or finger f. On the inner side of the side frame 101the rock shaft 50 carries a contact or radial pin 9 movable to flrst meet a shoulder or horizontal pin 10 projecting from a second rock-arm 1l mounted loose on said rock-shaft and thereafter to rock said arm 11. This rock-arm 11, is in turn connected by a link 12 to one end of a lever 13 carrying the controller stop-forming star wheel c that' normally engages a roll 14 carried rigidly with the driven spindle 5 1 and thus holds said spindle against rotation.

The article `carried by the feed mechanism collides with the setting device finger c and rocks it, which, through the link 7 and arm 8 moves the rock-shaft 50 against the slight pull of a spring 52 rto bring the radial pin 9 against the pin 10 as indicated by dotted lines, Fig. 12, and at the same time position the finger f in the path of movement of the actuating stud d as in`Fig. 10. rlhe parts will remain in this position so long as the setting finger c is held in its rocked position, Figs. l() and 11, by the continued presence of the article that has caused its movement and until in the course of its movement the actuating stud d makes contact with the finger f as in Fig. 11, and' thereby cause the radial pin 9 to rock the arm 11 and through the link 12 rock the stop carrying lever 13 against the pull of its spring 15 as indicated in Figs. 11 and 13 to release the controlling stop e from the roll 14 and allow the driven spindle 5l to rotate. As soon as the stud d passes the finger f the controlling stop e under the pull of its spring 15 returns to its original position in Figs. 1 and 10 ready to meet the stud 14 upon the completion of one turn of the driven spindle 15, and after having caused the article to be marked or counted Aor both marked and counted. And as soon as the article has passed beyond the setting finger c it and the movable finger f under the pull of the spring 52 return to the normal position shown in Fig. 1. The slotted end of the link 7 permits the rocking of the shaft 50 and arm 8 when moved by the stud d without necessarily moving said link and finger c.

The actuating stud d is moved in a circular path and in the present embodiment is conveniently carried by the feed controlling cylinder 20, or so as to make. turn for turn with said cylinder, so that for each article fed by the feed mechanism a movement of the controlling device will be effected. The time at whichthe actuatingl stud may meet and move the movable member f of the controlling device, with the result thatv the marking or printing of the article shall occur early or' later in the movement of said article and consequently be marked or printed at any desired point in its length, may be regulated and determined by changingr the location of said stud on the cylinder 20. For this purpose said cylinder-is formed on its outer end with an undercut groove 58 concentric with its axis and with the stud fitting saidjgroove and rendered in any proper way adjustable therein. When the feed controlling cylinder J20 is adapted -to feed more than one article during each rotation thereof as hereinbefore mentioned, the stud d or additional studs will be arranged to actuate the controlling stop c, once for each sheet fed.

The means for rotating the driven spindle 51 whenever it has been released in the manner just described consists in providing a constantly rotating or driving part such as a toothed wheel 53, Figs. 5 and 7, that is mounted loose on the spindle 51 and constructed to drive said spindle by a suitable friction device. f For lthis purpose the toothed Wheel carries a pair of disks 54,

one on each side of the toothed wheel in frictional contact with and between coacting disks 55 fast to the spindle. The frictional 'bearing faces of the disks 55 may be provided by fiber disks .1G to lessen the Wear. One of the disks 55 is formed integral with the head carrying the stop engaging roll 14 and is fixed to the spindle; and to compensate for the Wear of the frictional faces as well as to increase or diminish the frictional contact between the disks, the other disks 55 like the toothed wheel and its disks is longitudinally movable on the spindle toward the other or fixed disk 55 and is engaged and held against rotation with respect to the spindle bya slidable key 17 passing diametrically through said spindle and pressed against said movable disk bya suitable spring 18 within one end of said spindle, the tension of whichmay be regulated by a screw 19. i As the toothed wheel 53 constantly rotates in theoperation of the machine it results that as soon as the controlling stop e is removed from the roll 14 the 'spindle will immediately partake of the rotation of said toothed wheel by reason of the said frictional connections between .the toothed wheel and said spindle.

The printing roller 35 may be of the segmental form shown and is mounted on and secured to the projecting end of thel driven spindle 51 in any suitable manner. In the present instance it is secured in place by a wedge shaped spline 5G fitting a longitudinally inclined groove in the spindle and adjusted in place by the flange of a screw 57 threaded into the end of the spindle as in Fig. 7. By this means of securing the printing roller to the spindle the roller may be adjusted longitudinally or turned thereon so as to locate the printing surface in any desired position with respect to the spindle and its stop engaging roll 14.,

Certain members' of ther operating parts are mounted to yield with respect to coacting members to permit the machine to feed and handle articles of different thicknesses. Thus the grooved band-carrying roller 31 is mounted loose on a spindle carried by a rock arm 60, see Fig. 5, that is connectedl to one end of a suitable spring 61 to yield upwardly with respect to the carrying bands 21 and feed cylinder 20. The under grooved 1' roller 24 around which passes the bands'21, is secured to a driven spindle 62 mounted in a two-armed lever G3, see Figs. 6 and 7, to yield downwardly against the pull of a spring 64 with respect to the upper grooved roller 34 that is mounted on a driven spindle 76 supported in fixed bearings. The impression roller 36, preferably covered with rubber, is secured to a driven spindle 65 that is` mounted in a swinging frame 66, Figs. 6 and 7, to yield downwardly against the push of a spring pressed rod 67 with respect to the coacting printing roller 35;

' the upper position of the impression roller being limitedby its frame meeting the end of an adjusting screw stop 68.

Motion is communicated to the several operating parts, preferably, by means of a hand operated wheel 103 connected to rotate the main spindle 69 which carries the driving toothed wheel 70. l'lhis wheel 70 meshes with a pinion 71 mounted with another toothed wheel 72 on a transverse spindle 73. The toothed wheel 72 in turn meshes with a similar toothed wheel 74 fast to the spindle 75 to which the feed controlling cylinder 20 is secured, see Fig. 4. The toothed wheel 72 also meshes with a smaller and intermediate toothed wheel 77 rotating loosely on the spindle supporting the stop carrying lever 13, which wheel 77 meshes with and drives three other toothed wheels, one wheel 78 fast to the spindle 76 carrying the grooved roller 34, the driven toothed wheel 53 mounted on the spindle 51 and a toothed ,wheel 79 fast to the spindle 80 to' which the metal roller 40 is secured. The toothed wheel 78, meshes with a toothed wheel 81 fast to the yieldingly mounted spindle 62 which carries the grooved roller 24; and the toothed wheel 53 meshesy with and drives a toothed wheel 82 fast to the impression roller spindle 65.

As a means for operating a suitable `counting device D, Fig. 7, the driven spindle 51 has secured to its end a pin-carrying hub 83 arranged at each rotation of the spindle to impart a step movement to a suitably shaped gear 84, which through the sprockets on the hub of said gear, see Fig. 2, communicates its step by step motion through a chain 85 to a Vdriving pinion 86 in mesh with a` pinion 87 fast to the actuating spindle ofthe counter. The construction being such that at each rotation of the driven spindle 51 the units wheel of the counter will have been moved one step and then locked against rotation. Any suitable counting mechanism may obviously be employed, but that partly represented in the drawings is fully set forth and described in a'companion application filed by me in the U. S. Patent Ofiice on or about February 28th, 1906, Serial No. 303,336'.

The operation of the improved mechanism will have been understood from the foregoing description. 1t may be added, however, that the articles such as sheets or slips of paper or other material, preferably in quantity, are placed horizontally on the carrying bands 21 in proximity to the wiper holder 26 with their inner longitudinal edges against a suitable guide plate 104 'fixed to the outer side of the side frame 101. Motion being imparted to the gearing through the hand wheel 103 all the several parts will move with the exception of the driven spindle 51 and the instrumentalities with which it may be connected, such as the printing roller 35 and counting device D which remain at rest. Atl the appropriate moment the undermost sheet or slip on the carrying bands 21 which probably with others on the start of motion to the machine have been moved up to the bight of the wiper 25 and feed cylinder 20, will, when the high part 4 of the cylinder grooves and the cutaway portion 2 of said cylinder arrives approximately at the wiper, positively carry the loweirnost sheet forward beneath the wiper and thence between the bands 21 and 32 and thus separating it from the collection of sheets resting .on the bands 21. The

bands 21 and 32 carry the separated sheet forward to the" printing couple B and in doing so causes its leading end to collide with and rock the setting device finger c thereby moving the finger f into the path of movement of the stud d. This stud it should be remarked has been positioned in its groove in the cylinder 20 to cause the release of the driven spindle 51 at the moment when that portion of the sheet that is to receive the mark or impression will arrive 'in proper position on the impression roller 36 to be marked by -the printing roller 35 on the rotation of said spindle 51. This adjustment of the stud may for instance cause the printing roller to mark the leading end of the sheet,its tail end or any intermediate-place between its ends, according as it may be previously determined. The finger f, having been moved into operable position by the act of the sheet, will then be met by the stud d on the rotation of the cylinder-20, and moved so as to rock the controlling stop e away from the stop roll 14 thus freeing the driven spindle 51 and allowing it to rotate and thereby cause the sheet to be marked, and `if the counting device Dbe employed, have simultaneously counted the sheet. Instantly the stud d leaves the finger f the controllingstop e will return to itsnormal position 'ready to stop the driven spindle 51 upon the completion of a single rotation thereof.,

The specific details of the machine thus organized may obviously be changed and modified without departing from the scope of the invention; and other suitable feed mechanism maybe employed in lieu of that shown.
