- This invention relates to machines for printing addresses or other matter on periodical publications or the like and the salient object is to provide a novel automatic machine wherein a series of printing devices bearing address forms may be successively moved into printing position and wherein the periodicalsor the like may be successively fed into printing position'whereby an address may be printed upon each periodical.

Other objects are to feed the individual printing devices into printing'position and to automatically determine whether or not a printing device isto be printed so that impressions may be made from some of the printing devices while others will be as it is termed skipped; to interrupt the feed for the periodicals when a' printing device is to be skipped; and to retain a printing device from which an impression is to be made in-printing position in the event no periodical is fed.

* Heretofore periodicals have usually been fed into machines of the character to which this invention appertains by hand or they have been fed into the machine'automatically from a stack disposed adjacent the receiving endof the machine. 'Ihehand operation is expensive and requires one or more operators. The automatic stack feed time operation does'not always prove satisfactory in that more than one periodical is sometimes fed into the machine thereby preventingproper operation; It istherefore a. still further object to provide a novel feedingmechanism which will automatically feed only one periodical at a time into the machine and which will be positive and constant in operation.

Still further objects are to provide intermittently operating traveling chains for feeding the periodicals to the machine, to feed the periodicals I into printing position in. the machine after move I Fig. 3 is a longitudinal sectional view taken,

In the accompanying drawings, 1 is a suitable frame in which a drive shaft 2 is journaled-having a flywheel 3 on one end thereof driven by suitable means such as an electric motor (not shown). A handle 4 may be provided on the'flywheel for operating the machineby hand when so desired. A collar 5 rotates with the shaft and is rigidly mounted on 'the shaft 2 adjacent the flywheel. A pawl 6 on the collar is arranged adjacent the flywheel and is adapted to engage a slot in the shaft 2. The pawl 6 operates with the arm 8 (Fig. 4) which forces it into or out of the slot, a spring 9 normally holding the pawl inwardly. This mechanism forms the main clutch 10 that is clearly illustrated in Fig. 4. A gear 11 on the shaft 2 meshes with a gear 12v on the cam shaft 13 to operate the mechanism for feeding periodicals one at a time into the machine. The cam shaft 13 extends transversely across the machine and the ends thereof are mounted in suitable journals 14 and 15 in the feed mechanism casing 16. On the cam shaft 13 is a main gear 17 that drives a gear 18 (Fig. 1) mounted'on the shaft 19 of the belt conveyor through the idlers 20 and 20 (Fig. 1) journaled in the side of the casing 16; The wide idler gear 21 (Fig. 5) mounted on the stub shaft 23 is meshed with both gears 1'7 and 22. The gear 22 is fast on the shaft 26. Pulleys 2'7 spaced on shaft 26 are free to rotate with the shaft. Spaced from shaft 26 is a shaft 28 carrying pulleys 29. A pair of belts 30, 30' are directed about these pulleys as shown in Fig. 2. The pulleys are positioned and are of suflicient diameter to allow the bottom, edges of the belt to just clear the top of the machine and render suflicient friction to al- 7 low the articleto be printed to be carried longitudinally across the machine. As shown in Figs. 1 and 2, the shaft 28 is supported by uprights 31 mounted on the frame and these uprights have their bases groovedat 32 to permit longitudinal adjustment thereof. A gripper roll'rocker 35 is mounted on shaft 34 (Fig. 5) supported by a hanger 33 connected to the casing 16 and extending downwardly therefrom. A pair of juxtaposed arms 36 rigidly formed on the rocker 35 carry a shaft 37. A lever 38 is pivotally mounted on this shaft and carries a roller 39 riding on a cam 40 fixed to shaft 13. A spring 41 attached to the upper end of 'lever 38 holds roller 39 against cam 40 and rotation of the cam moves lever 39 rectilinearly, which motion is transmitted to gripper roll rocker 35. Arms 42 on rocker 35 support a shaft 43 on which the gripper rolls 46 are mounted. A shaft 47 mounted in the frame carries agear 48 driven from the main gear 17 through idler gears and 45' (Fig. 1). Feed rollers 50 are fast on shaft 47 opposite the gripping rollers 46. The rollers 46 and 50 are driven to rotate in opposite directions so that when the gripper roll rocker reciprocates toward the feed roller shaft 47 the article to be printed is grasped or clamped between the rollers and fed into the machine. In order to provide positive feeding of the periodical or other article to be printed, a pneumatically operated feed is provided comprising a rockable hollow rod or sucker bar 51 having one end pivotally connected to a valve casing and the other end connected to the side of casing 16 by an arm 53 that is free'to travel in a slot 54 in'the casing (Fig. 1). Means (such as an air compressor which is not shown) are provided for creating a vacuum in the sucker 1 bar. On the stud 5 5 (Fig. 3) extending inwardly from casing 16 are two levers 56 and 57. The sucker bar. 51 has open ends 51 movable between the shafts 43 and 47 to engage forward marginal edge portions of the bottom periodical of the stack to pull it downwardly and partly around the feed roller so that the gripper roller may clamp this bottom-periodical against the feed rollerto withdraw. the bottom periodical from the stack. While the sucker bar is thus operating the fingers 65, to be described, are sunk away from the stack and after the sucker bar has pulled the front portion of the periodical downwardly thefingers again engage the stack to prevent other periodicals from being affected while the magazine is being fed away. A pneumatic valve 66 (Fig. 3) in the valve casing is timed to create suction when the feed roller moves toward the periodicals and upon reverse movement this valve shuts off the sucking action and releases the grip on the periodical at approximately the same time the. rollers 46 and 50 engage the pe- 'riodical to carry it on into printing position. The

periodicals are arranged at the right hand end of the machine as viewed in Fig. 1. To feed the periodicals a chain feed shaft 153 (Fig. 10) is juxtaposed to the feed roller shaft and carries a* plurality of sprockets 154 and is rotated by a ratchet-155 fixed to one end thereof. Endless chains 156 arearranged on these sprockets and connect the chain feed shaft with another shaft (not shown) to move the chain along the table 157 to carry periodicals stacked thereon to feeding position. A bell crank 158 is loosely mounted on the chain feed shaft 153 and carries mechanism to rotate this shaft. One arm (Fig. 11) of the bell crank has a stud 160 fixed thereto to which one end of a link 161 is pivotally connected.

The other end of this link is pivotally connected to a stud 162 fastened to the gear 12. A pawl 163 is pivotally connected to the arm 164 of the bell crank for operating the ratchet. A spring 165 has one end connected to the pawl and the other connected to a lug 166 on the bell crank for normally holding the pawl against the ratchet. The cam shaft 13 has a cam 167 rigidly fastened thereto which operates against a roller 168 mounted on a cam lever 169 to reciprocate the cam lever. The upper end of the cam lever is pivotally connected to the feed control rocker 170 and reciprocates the same. A spring 171 normally holds the cam lever in operative posi tion against the cam. The feed control rocker 170 (Figs. 11, 12 and 13) has downwardly disposed feed control fingers rigidly connected thereto and against which a periodical strikes as it is being fed into the machine. Pressure against these fingers causes movement of the feed control rocker which is transmitted to the cam lever 169. When the feed control rocker is moved inwardly, the roller 168 is moved a short distance away from the cam 167 so that the cam only works on the roller at certain points and gauges the distance the arm 173 is to travel in operating the pawl 163. When the feed control fingers are moved inwardly substantially the full distance of this inward travel, the roller 168 is entirely removed from the cam 167 and when no movement is transmitted to the arm 173, the pawl is held away from the ratchet. To prevent a periodical from pushing the feed control fingers too far inwardly and prevent action of the pawl on the ratchet, a plurality of downwardly disposed stop fingers 145 are fixed on the frame in front of the feeding end of the machine to limit this feed of the periodical so that the pawl may be free to work the ratchet thus assuring proper feed of periodicals into the machine. When the periodicals are fed staggardly into the machine and while the feed control rocker reciprocates, the feed control fingers determine the movement of the arm 173 which controls the movement of the chain feed shaft for gauging the proper movement of the chains so that the periodicals will be continuously and properly fed into themachine. The sucker bar is timed so that on its forward movement there is a suction-in the bar for assisting in pulling the periodical into the machine and then release the periodical at the proper time by shutting off the suction. The lowermost periodicals should normally abut against the stationary stop fingers 145. If the lowermost periodicals do not abut against the fingers the oscillating feed control or feeler fingers 65 will move to the left (Fig. 12) to make contact with the front edges of the said periodical and the chain will operate to feed the lowermost periodical to the right (Fig. 12) into contact with the stationary fingers 145. Thus, the bottom periodical is positioned to be pulled downwardly by the sucker bar, as above described. In operation periodicals are arranged on the feed chains which travel along the table 157, due to rotation of the chain feed shaft, and place the periodicals on the feed shelf where they are propelled inwardly by the feed rollers, it being assumed that a printing device has been selected for printing and is in the proper printing position. The pneumatic suckers then pull the forward end portion of the bottom periodical downwardly between the feed rollers and the gripper rollers. The finger bar rocks forwardly and the finger bar fingers prevent more than one periodical from have gone through one cycle of operation and is again ready to feed and print another periodical. If, however, the selector-mechanism, to be de scribed,*is not functioning, or a printing device is not in printing position, or certain printing (18-. vicesnot to. be printed are fedinto the machine, the selector mechanism will operate to shut off the suction in the sucker bar and will move the I finger bar fingers to obstruct the feeding end a fan,

of the machine so that no periodicals will be fed into the machine. The belt conveyor, referred to, comprises shafts 19. and and shafts 71 and 72. Rollers 73 over which endless belts 74 are directed are mounted on these shafts and movement is imparted thereto from the belt roller shaft 19, the roller 73 on the shaft 19 being fast thereto while the other rollers are rotatably mounted on their respective shafts. The belts 74 carry the periodical to printing position and after it is printed they carry it beyond, the machine to a suitable table or receptacle (not shown) Suitable belt tighteners' 75 take up the slack in the belt 74. A longitudinal cam shaft 76 (Fig. 2) on the rearward side of the frame receives motion from. the drive shaft 2 through bevel gears '77 and 78. The platen 82 (Fig. 9) iscarried by a platen arm shaft 83 mounted in the frame of. the machine and is operable by cams provided on the shaft 76, this arrangement being shown in Letters Patent No. 1,481,860, patented January 29, 1924. A printing device magazine 85 is arranged at the rear of the machine medially thereof into which printing devices are introduced'which'are withdrawn therefrom and fed into printing position by intermittently oper-. atedfeed chains 87 which move a printing device through selecting position before moving it into printing position. The feed chains are arranged in parallel relation and are directedabout sheaves 90. and about sprockets 91 to be driven'thereby.

' The. sprockets are fixed toa shaft 92 (Fig. 6) and one of the sprockets has a number of projecting pins 93 -thereon. A pawl 94 carried by an arm 95 successively engages these pins to turn the sprockets and thereby impart a step-by-step movement tothe chains. The arm 95 is part of a rocker 96 and is actuated through suitable connections by cams on shaft 76. (See Fig; 9.) After the printing devices have been. moved through printing position they are engaged by a suitable packer rocker 102 (Fig. 1) so timed and constructed that as soon as the printing device 7 falls into a storage drawer supported below the printing deviceguideway, the packer urges the device and the preceding devices rearwardly in thev drawer to permit the passage of succeeding carries an upwardly extending arm 105' having a cam roller 106 thereon (Figs. 1a and 2). This roller rides on a cam 107 fast on driving shaft 2. One end of a spring 105" is fastened to bar 105 and the other end is fast to the frame to thereby hold roller 106 against cam 107. The forward end of bar 105 carries a clutch member 108 (Fig. 1) engageable with a clutch member 109 (Fig. 1) fast on the rod 110 communicating with clutch 10 on flywheel 3. When the clutch members are engaged as shown in Fig- 3 the machine is in operating position, but when disengaged the pawl 6 is held from engagement with the flywheel and therefore the machine is inoperative. When the roller 106 rides onto the low portion of cam 107 it moves bar 105 outwardly and also moves the clutch members 108 and 109 out of engagement, thereby lifting the rod 110 and disengaging the clutch 10. The arm 8 disengages the pawl 6 from the slot in the drive shaft 2 thereby interrupting operation of the machine and the drive shaft will operate idly. However, this condition is only desired when no printing device is to be fed. Therefore means are provided to hold the clutches in engagement when the printing device is operating properly. A rod 111 (Fig. 1) connects bar 105 to pivoted finger 112 (Fig. 9) arranged on the periodical rack. When the printing devices are arranged in the magazine, the finger 112 acts through rod 111 to move bar 105 outwardly, thereby holding the cam roller 106 from movement into the low spot of cam 107 and thus the clutch members 108 and 109 are held in engagement with each other. When there are no printing devices in the magaine the roller will move onto this low spot to disengage the clutch members and interrupt operation of the machine. When a printing operation is being performed the periodical or other article being printed is held against movement and this is attained by providing stops 113 and 114 (Fig. 1) to hold the periodical against movement with the belt during a printing operation. The stop 114 holds the periodical being printed against movement and the stop 113 prevents the succeeding periodical from being fed against or on top of the one being printed. Each stop comprises fingers 115 projecting from a bar 116 rigidly connected to a rod 117 supported in suitable bearings 118 carried by the frame and is provided with arms 119 (Fig. 3) supporting rollers 119 which lightly rest on the article to insure movement thereof with the belt. An arm 121 (Fig. 5) secured to the end of the bar 116 carries a roller 122 that is loosely mounted thereon. This roller rides on a cam 123 fast on longitudinal shaft 124 driven from shaft 19 through gears 125 and 126. When the rollers 122 ride onto the low portion of the cams the stops 113 and 114 fall downwardly by their own Weight. When the rollers move onto the high portion of the cams the stops are raised and when in this position the periodicals are free to be moved by the belt 74. The selecting mechanism of this machine operates in the manner described in the patents previously referred to, to determine or select some printing devices to be printed while others are, as it is termed, skipped. When a printing device is skipped a periodical is not fed into printing position and thus the periodicals are prevented from passing through the machine without receiving a printing impression. Furthermore, means are provided whereby the failure of a periodical to feed into printing position will prevent the discharge of a printing device from printing position that has been determined to be printed until a periodical moves into printing position. A rod 127 (Fig. 6) is connected at one end to an arm 127'" on a rod 127 which extends transversely in the frame. The other end of the rod 127 is connected to an angle lever 227 pivoted at 227 on the frame and adapted to engage a pin 227" on pawl 94 for releasing the pawl from pin 93 on sprocket 91. A spring 128' attached to the arm 127 and to the frame normally holds these parts in position with the pawl 94 out of operative relation to the pins 93 on the sprocket; but when a periodical is fed to printing position it will depress a roller 129, which is mounted on the arm 128 and projects up through an opening 130 in the table 130 of the machine, and the rod 127 is thus shifted to the right (Fig. 6) and the pawl 94 is then permitted by the angle lever 227 to engage one of the pins 93 for operating the printing device feed. In the absence of a periodical for depressing the roller 129, the feed pawl 94 will be held in inoperative position so that the printing device feed will not operate and this is desirable because a printing device to be printed should not be discharged from print ing positionuntil an impression has been taken therefrom. For insuring proper engagement of the periodical with the release roller 129 a double roller 134, carried by a rod 133 on a support 132 on the. frame, is arranged over the opening 130 in the table. When'there is no periodical present under the rollers 134 the release roller 129 will be projected by the spring 123' through the opening 130 in the table and between the rollers 134, as shown in broken lines in Fig. 6, and the feed pawl 94 will then be in inoperative position; but when a periodical is fed beneath the rollers it will force the release roller down against the tension of its spring 128 and cause the printing device feed to operate. A handle arm 131 is connected to the arm 127', which is in the form of a casting mounted on the rod 127 and forming a support for the arm 128 so that the printing device feed control may be operated manually when desired. This handle also functions as a counterweight to supplement the spring 128'. The handle arm 131 has a roller 135 thereon which rides on a cam 136 fastened on shaft 124. When the roller rides onto the low portion, of the cam 136 the wheel 129 is free to rise through the slot 130 and when the roller is ona high portion of the cam the wheel 129 is held downwardly. This arrangement permits a printing device to pass to printing position where it is retained for a printing operation. A bar 137 at the left hand end of the machine (Fig. 2) is similar to the stops 113 and 114. This bar serves to retard the movement of the periodical onto the receiving table and afford sufficient pressure to allow the periodical to be propelled by the belts 74. To prevent a periodical from being fed to printing position when a printing device is to be skipped a yoke 138 (Fig. 11) is pivoted to the frame and is operated by a rod 139 connected with selector pin bar 104. When the selector pin bar is operated by a printing device to be skipped, the yoke 138 is reciprocated. A bell crank 139 pivotally mounted on the frame carries a roller 140 which contacts with an edge of the frame and during reciprocation of the yoke this bell crank is moved. An arm 141 of the bell crank is connected to a rod 142 communicating with the arm of the pneumatic valve 66. Movement of the arm 141 causes rod 142 to move longitudinally and prevents reciprocation of the arm 69 thereby shutting off suction in the bar 51 to prevent the bar from drawing a periodical into the machine. A rod 143 is connected to the arm 141 and is operated in the same manner as rod 142 and prevents reciprocation of the finger bar170. When the finger bar is stopped it will be in the position shown in Fig. 3 and periodicals will be prevented from feeding. The periodicals travel in suitable guides fastened to the top of the frame to assure proper positioning thereof relative to the platen and also to assure proper orientation during a printing operation.
