My present invention relates to printing machines of the type utilizing the spirit transfer process and master elements having spirit responsive transfer material thereon for the printing of sheets of paper and the like.

More specifically, this invention involves a machine for printing the names and addresses of intended recipients, or similar data, on form letters or other mailing pieces and various types of inter-ofiice record material and the like.

An important object of my invention is the provision of a printing machine as set forth which is capable of receiving master cards or sheets of various sizes and shape, and which is capable of printing the required material on sheets of greater lateral dimension than that of the machine. To this end, I provide a printing machine comprising a base, a generally vertical support member extending upwardly from one side of the base, and cantilever structure extending transversely from said support member in overlying spaced relation to the base and defining therewith a passage for sheets to be printed, said passage having an open side so as topermit feeding through the machine of sheets having a greater lateral or transverse dimension than the lateral dimension of the passage.

Another object of my invention is the provision of a printing machine of the above type having a novel construction and arrangement which permits feeding therethrough of a master card or sheet having a greater dimension transversely of feeding movement thereof than said machine.

Still another object of my invention is the provision of a printing machine having no-vel means for feeding a sheet and master card toward each other and toward a common printing zone from spaced apart portions of the machine.

Another object of my invention is the provision of sheet-feeding means and master card-feeding means and control means responsive to insertion into the machine of a master sheet or card to energize the sheet-feeding means and card-feeding means.

Another object of my invention is the provision of means for adjusting said control means whereby to vary the timing of initiation of the card-feeding means relative to that of the sheet-feeding means, to adjust the position of a sheet to be printed relative to a cooperating master card at the printing zone of the machine.

Yet another object of my invention is the provision of novel means for guiding a master card and a printed sheet in different directions during discharge thereof from the machine, and of means for receiving the printed sheet and for stacking the used master cards in a predetermined order.

Another object of my invention is the provision of a printing machine comprising, a frame structure including a base having a magazine at one end for sheets to be printed, a generally vertical support member extending upwardly from one side of said base, a pair of spaced parallel cantilever arms extending laterally from said support member in overlying spaced relation to the base and defining with said base a passage for sheets to be printed, said arms cooperating to define a passage for master cards, said passages being opened at the side of 3,245,342 Patented Apr. 12, 1966 said machine opposite said support member, sheet-feeding means for feeding sheets singly from said magazine and between said space and cantilever arms toward a printing zone adjacent the opposite end of the base, cardfeeding means including coooperating card-feeding elements on said cantilever arms for feeding a master card in a direction generally toward a sheet delivered by the sheet-feeding means and toward said printing zone, sheetmoistening means for applying solvent liquid to said sheet during feeding movement thereof to said printing zone, means including a pair of cooperating rotary pressure and feed cylinders, one in said base and the other in one of said cantilever arms at said printing zone, for pressing the master card and moistened sheet together therebetween and for discharge of said card and sheet from said printing zone, drive means for imparting feeding movements to said sheet-feeding means and card-feeding means and rotary discharge movement to said feed cylinder, and a receiver for said card and sheet and including a sheetreceiving tray, a card storage rack, and a transfer device for stacking a plurality of said master cards in predetermined order on said rack responsive to discharge of said cards to said receiver.

The above, and still further highly important objects and advantages of my invention will become apparent from the following detailed specificaton, appended claims and attached drawings.

FIG. 16 is a schematic wiring diagram.

In the preferred embodiment of the invention illus trated, the numeral 1 indicates, in its entirety, a generally rectangular base having a top wall 2, and opposed

side walls

3 and 4 that are connected by

transverse frame members

5, 6 and 7 and a transverse flange 8. The flange 8 and frame member 7 are disposed at one end of the base 1, the transverse member being disposed at the opposite end thereof. The transverse member 6 is disposed intermediate the opposite ends of the base 1 and provides a stiffening element for the top wall 2, as does a transverse reinforcing bar 9.

The side wall 4 is formed to provide end flanges 10 and 11 and a horizontally disposed top flange 12, and extends upwardly from the level of the top wall 2 to provide a support member for cantilever structure involving a pair of

cantilever arms

13 and 14 that are bolted or otherwise rigidly secured to the upper end portion of the side wall 4 in overlying spaced relation to the top wall 2 and in spaced relation to each other. The free ends of the

cantilever arms

13 and 14 terminate substantially in the plane of the base side wall 3, the

arms

13 and 14 cooperating with the top wall 2 of the base 1 to define a generally horizontally disposed passage 15 for sheets or the like to be printed. Further, the

arms

13 and 14 cooperate to define a sloping passage 16 for master sheets or cards, the passage 16 sloping downwardly toward the passage 15 and merging therewith at a printing zone indicated generally at A adjacent one end of the base 1. It will be noted that the

passages

15 and 16 are open at the side adjacent the side wall 3 of the base 1 whereby to accommodate sheets and master cards of width which would cause the same to project laterally outwardly beyond the side wall 3 of the base 1.

At its end opposite end printing zone A, the top wall 2 cooperates with a supporting device 17 and a pair of

adjustable guide members

18 and 19 to provide a magazine for a plurality of envelopes, sheets or the like, to be printed. For the purpose of the present example, a plurality of sheets of paper are shown and indicated by the reference character X. The supporting device 17 comprises a supporting block 20 having a horizontally disposed flange 21 extending therefrom toward the top wall 2 and disposed substantially in the .plane of the top wall 2, a depending leg 22 and a pair of laterally spaced mounting rods or bars 23 extending longitudinally of the base through spaced flanges 24 in the transverse frame member 7. The mounting rods 23 are rigidly secured to the lower end portion of the leg 22 and are longitudinally slidable through the flanges 24 whereby the block 20 may be adjustably moved toward and away from the base 1. The

upstanding guide members

18 and 19 are provided with depending

anchoring tabs

25 and 26 respectively disposed in face-to-face engagement with the outer surface of the flange 8, and are releasably locked in engagement with the flange 8 by nut-equipped locking screws 27 that extend through suitable apertures in the

tabs

25 and 26 and through a pair of horizontally elongated slots 28 and 29 in the end flange 8 of the base 1, see particularly FIGS. 5, 7, 9 and 11. As shown by full and dotted lines in FIG. 11, the

guide members

18 and 19 may be adjusted to receive sheets X of various widths including sheets having a width greater than that of the base 1.

The afore-mentioned magazine is further defined by a plurality of axially spaced separator rolls 30 that are mounted on an elongated shaft or bolt 31 extending transversely of the base 1, the rolls 30 being separated by tubular spacers or the like 32 on the bolt 31. Adjacent its opposite ends, the bolt 31 is mounted on a pair of lever arms 33 that are pivotally mounted in brackets 34 anchored to the cantilever arm 13 by means of screws or the like 35, see FIGS. 4, 5, 11 and 13. The separator rolls 30 are urged in an upward direction away from the base 1 by coil tension springs 36 anchored at their lower ends to the spacers 32 and at their upper ends to the brackets 34, upward movement of the separator rolls 30 being limited by engagement of the lever arms 33 with adjustable stop screws or the like 37 that are screw threaded in the brackets 34, see particularly FIG. 13. The separator rolls 30 are held against rotation by the tightening of a nut 38 on one end of the bolt 31, the peripheral surfaces of the separator rolls 30 engaging the leading edges of the sheets X, as seen in FIG. 1, and being spaced above the top wall 2 of the base 1 only slightly greater than the thickness of one of the sheets X.

Primary feeding means for the sheet X comprises a plurality of generally segmental feeding drums 39 having radially inwardly extending flanges 40 mounted for limited radial movements on a transverse shaft 41 that is journalled in its opposite ends in suitable hearings in the

base side walls

3 and 4. The feeding drums 39 are disposed in spaced apart relationship axially of the shaft 41 and are anchored together by a pair of. laterally spaced parallel nut-equipped tie bolts 42 and tubular spacers 43. An elongated crankshaft 44 is journalled in the flanges 40 of the feeding drums 39 intermediate the tie bolts 42 and is provided at its opposite ends with crankpins 45 one of which is eccentrically journalled in a stub shaft 46 fast on an adjustment plate 47 that is journalled on the outer end of a radial arm 48 that is keyed or otherwise rigidly secured to the shaft 41 for common rotation therewith. The adjustment plate 47 is provided with a plurality of circumferentially spaced apertures 49 that selectively receive a detent 50 on the radial arm 48 to selectively hold the adjustment plate in desired adjusted relationship to the radial arm 48. The crankpin 45 at the opposite end of the crankshaft 44 is journalled in the radially outer end portion of a second radial arm 51, as shown by dotted lines in FIG. 7, the arm 51 being secured at its inner end to the shaft 41 in the same manner as the radial arm 48. Adjustment of the plate 47 causes the group of feeding drums 39 to move radially of the shaft 41 for adjustment of the feeding drums 39 relative to the top wall 2, each feeding drum 39 being provided with a sheet-engaging tire 52 of rubber or the like.

Means for imparting feeding rotation to the primary feeding drums 39 includes a continuously-operated motor 53 that is controlled by a switch 54, a single-revolution clutch mechanism 55, and a drive belt 56. The motor 53 is mounted on a bracket 57 that is supported by the

transverse frame members

5 and 6, the clutch mechanism involving a pair of cooperating

clutch elements

58 and 59 the former of which is mounted on the shaft 60 of the motor 53 for common rotation therewith. The clutch element 59 is keyed or otherwise secured to a shaft 61 for axial sliding movements thereon and for common rotation therewith, the shaft 61 being axially aligned with the motor shaft 60 and journalled in the side wall 3 and in a mounting plate 62 secured in laterally inwardly spaced parallel relation to the side wall 3 by mounting legs or the like 63. A cam 64 is mounted on the clutch shaft 61 for common rotation therewith, and has mounted thereon a bracket 65 to which is pivotally secured a shifter fork 66 having pin and slot connections 67 with the clutch element 59. The clutch element 59 is yieldingly urged toward engagement with the clutch element 58 by coil compression springs 68 interposed between the clutch element 59 and the hub of the cam 64. This engagement of the

clutch elements

58 and 59 against bias of the springs 68 is effected by a cam member 69 and a cam follower element 70, the latter of which is mounted on the shifter fork 66. The cam member 69 is integrally formed with an arm 71 which overlies the

clutch elements

58 and 59 and which is pivotally secured to mounting cars 72 on the bracket 57, one of said ears being shown in FIG. 8. The outer or free end portion of the arm 71 rides on the peripheral cam surface of the cam 64 and is adapted to be engaged by a hook element 73 projecting laterally from the lower end of a leg 74 the upper end of which is pivotally connected to one end of a bell crank lever 75 that is pivotally connected to the bracket 57, as indicated at 76. The other end of the bell crank 75 is pivotally connected to the armature 77 of a solenoid 78 mounted on the bracket 57, see particularly FIG. 8. With the parts positioned as in FIGS. 5 and 8, energization of the solenoid '78 causes the leg 74 to move upwardly and inwardly toward the arm '71 to move the cam member 69 out of engagement with the cam follower element 70, permitting the springs 68 to move the clutch element 59 into engagement with the clutch element 58. The depending leg 74 is provided with a tongue 79 that engages the cam 64- to move the hook-like element 73 out of engagement with the arm 71 during rotation of the

clutch elements

58 and 59. Upon completion of a single revolution of the clutch element 59 and cam 64, the cam 64 permits the arm 71 to drop into a position wherein the cam 69 will engage the cam follower element 70 to disengage the

clutch elements

58 and 59. The cam 64 then permits the depending leg 74 to drop into a posi tion wherein it can engage the arm 71 upon a subsequent energization of the solenoid 78. A second cam follower 80 is mounted on the outer end of a crank arm 81 pivotally secured to the mounting plate 62, as indicated at 82, and is yieldingly urged toward engagement with the cam 64 by a coil spring 03. A stop pin 84 on the plate 62 limits spring biased movement of the cam follower 80 toward the cam 64. The drive belt 56 is entrained over a cooperating pulley 85 fast on the shaft 61 and a second pulley 86 fast on the transverse shaft 41; and over-running of the feeding drums 39, when the clutch 55 is disengaged, is prevented by engagement of the cam follower element 70 with a depending portion of the arm 71, as shown in FIG. 5. Rebounding of the cam follower element 70 from said depending portion of the arm 71, and resultant reverse rotation of the feeding drums 39 is prevented by engagement of the cam follower 80 with the cam 64. With reference to FIGS. 4, 5, 7 and 10, it will be seen that the feeding drums 39 work through apertures 87 in the top wall 2 intermediate the separator rolls 30, the peripheral surfaces of the tires 52 frictionally engaging the bottom surface of the lowermost sheet X to be printed and imparting initial advancing movement to said lowermost sheet toward the printing zone.

Secondary feeding means for the sheets X comprises a pressure roller 83 mounted fast on a horizontally disposed transverse shaft 89 that is suitably journalled in the

side walls

3 and 4, the pressure roller 88 projecting upwardly through an opening 90 in the top wall 2 and underlying a moistener roll 91 that is journalled in a bracket or holder 92 secured fast to a mounting shaft 93 that is journalled in the cantilever arm 13 and the side wall 4 of the base 1. A moistening wick 94 is carried by a duct 95 in the holder 92, the wick 94 engaging the peripheral surface of the moistening roll 91, the duct 95 being connected to a reservoir 96 mounted in a holder 97 on the upper portion of the side wall 4, through a flexible tube 98 extending from the holder 97 to the duct 95. A leaf spring 99 secured to the shaft 93 maintains the wick 94 in engagement with the moistening roller 91.

The mounting shaft 93 extends outwardly through the side wall 4, and has mounted on its outer end a radial arm 100 that is engaged by a torsion spring 101 which yieldingly urges the mounting shaft 93 in a direction of rotation to move the moistening roll 91 in an upward direction away from engagement with the underlying pressure roller 88. At its outer end, the radial arm 100 is attached to one end of a coil tension spring 102, the other end of which is attached to the armature 103 of a solenoid 104 suitably mounted on the side wall 4 adjacent the upper edge thereof. The spring 102 is stronger than the torsion spring 101 so that, when the solenoid 104 is energized, the radial arm 100 is moved in a direction to lower the moistening roller 91 toward engagement with a sheet X passing th-erebetween and the underlying pressure and feed roller 88. A stop flange 105 limits outward 6 movement of the armature 103 with respect to the solenoid 104.

Intermediate the primary feeding drums and the secondary feeding means comprising the roller 88 and moistening roller 91, is disposed intermediate feeding means comprising a plurality of power-driven feed rolls 106 and cooperating pressure rolls 107, the former being mounted fast on a horizontally disposed transverse shaft 108 that is journalled at its opposite ends in the

side walls

3 and 4, the feed rolls 106 projecting upwardly through openings 109 in the top wall 2. The pressure rolls 107 are mounted in slotted brackets 110 carried by the cantiliver arm 13, and are yieldingly urged toward engagement with their respective underlying feed rolls 106 by suitable means, such as by torsion springs 111, see particularly FIG. 13.

A pair of cooperating printing and

discharge cylinders

112 and 113 are disposed at the printing zone A, the former being mounted fast on a horizontally disposed transverse shaft 114 journalled at its opposite end portions in the

side walls

3 and 4, and the latter of which is journalled in a yoke 115 that is carried by the cantilever arm 14 and yieldingly urged toward engagement of the cylinder 113 with the underlying cylinder 112 by a coil compression spring 116. Adjustment of the yielding bias of the spring 116 is had through a conventional adjustment nut 117 in a manner well known to those skilled in the art.

The

shafts

89, 108 and 114 outwardly of the side wall 4 have fixed thereon

respective gears

118, 119 and 120, these gears being connected by

idler gears

121 and 122, for rotation in a common direction and at equal speeds, the

rollers

88, 106 and cylinder 112 being preferably of equal diameter. These are driven from the shaft 41 by a gear 123 fast on the shaft 41, an idler gear 124 suitably journalled in the base 1 and having meshing engagement with the gear 123, and a pinion 125 fast on the shaft 108 and in meshing engagement with the idler gear 124, see FIGS. 3 and 4.

Means for feeding spirit-responsive printing sheets, hereinafter referred to as master cards, to the printing zone A, comprises an elongated card-feuding tray 126 and mechanism now to be described. The card-feeding tray 126 overlies and is secured to the cantilever arm 13, said tray having upturned and downturned stiffening

flanges

127 and 128 respectively at its opposite side edge portions, the former being disposed adjacent the side wall 4 and the latter substantially overlying the side wall 3 of the base 1. As shown, the tray 126 slopes downwardly toward the printing zone A, and has adjustably mounted to its upper surface a pair of laterally spaced transversely

adjustable guide members

129 and 130 for reception of master cards therebetween, a master card being shown in FIG. 7 and indicated by the reference character B. As shown in FIG. 2, the guide member 129 is formed with a base flange 131 that rests upon the top surface of the tray 126 and is adjustably secured thereto by a nut-equipped screw 132 extending downwardly through a transverse slot 133 in the tray 126. The guide member 130 is formed to provide a transversely elongated mounting tongue 134 that extends through suitable slots or apertures in the guide member 129 and upturned flange 127, the tongue 134 having therein a slot 135 for reception of a nutequipped anchoring screw 136 that extends downwardly through a suitable aperture in the tray 126 to releasably anchor the guide member 130 in desired adjusted position.

A plurality of power-driven card-feeding rolls 137 are mounted fast in axially spaced relation on a horizontally disposed transverse shaft 138 that is journalled at its opposite end portions in the upper portion of the side wall 4 and in an outer end Wall 139 of the contilever arm 13. The card-feeding rolls 137 project upwardly through opening s 140 in the card-feeding tray 126 and underlie a like plurality of cooperating pressure rolls 141 that are journalled on a horizontally disposed transverse shaft 142 supported at its opposite ends by radial arms 143 that are mounted fast on a transverse rock shaft 144 journalled at one end portion in the upper portion of the side wall 4 and at its opposite end in an end wall 145 of the cantilever arm 14. As shown in FIGS. 3 and 4, an actuator arm 146 is mounted fast on one end to the projected end of the rock shaft 144, and has its opposite end pivotally connected to the armature 147 of a solenoid 148 suitably mounted on the side wall 4 adjacent the top flange 12 thereof. A coil compression spring 149 anchored at its opposite ends to the side wall 4 and actuator arm 146 yieldingly urges the actuator arm 146 in a direction to move the pressure rolls 141 upwardly away from engagement with their respective underlying card-feeding rolls 137. As shown in FIG. 3, the card-feeding rolls 137 are driven from the gear 118 by means of a pinion 150 fast on the shaft 138 and an idler gear 151 suitably journalled from the side wall 4 and having intermeshing engagement with the gear 118 and pinion 150.

An angle plate 152 is suitably mounted on the cantilever arm 14 and carries a plurality of guide fingers 153 to guide the master cards B into the space between the

rolls

137 and 141. A pair of displaceable stop fingers 154 has end portions that normally project upwardly through the openings 140 to limit movement of the master cards B toward the printing zone A, as will hereinafter be described. The stop fingers 154 are rigidly secured to a rockshaft 155 that is journalled at its opposite ends in the side wall 4 and end wall 139 on a horizontal axis extending transversely of the machine. Outwardly of the side wall 4, as shown in FIG. 3, the rockshaft 155 has mounted fast thereon a crank arm 156 that is connected at its outer end to the actuator arm 146 by means of a rigid link 157. When the solenoid 148 is energized, resultant movement of the actuator arm 146 causes the stop fingers '154 to be retracted downwardly out of the path of travel of the master card B on the tray 126, thus permitting movement of the master card B toward the printing zone.

The

solenoids

78, 104 and 148 are controlled by respective ones of a plurality of

switches

158, 159 and 160. The switch 158 is mounted within the cantilever arm 14 by means of a mounting flange 161, and is provided with a depending actuator finger 162 that extends downwardly across the passage 16 in the path of feeding movement of a master card B. The switch 159 is mounted to the interior portion of the cantilever arm 13 and is provided with a depending actuator finger 163 that extends downwardly across the passage 15 in the path of travel of each sheet X as it is fed from the magazine toward the printing zone A. The switch is mounted within the cantilever arm 13 by means of a bracket 164, see FIG. 9, and is provided with an elon gated switch-operating crank 165 that cooperates with an actuator finger 166 to energize or deenergize the switch 160. The actuator finger 166 is pivotally connected at one end to the lower end of an adjustment bar 167, by means of a pivot pin or the like 168, the pivot pin 168 extending transversely through an elongated slot 169 in a vertically disposed partition member 170 depending from the cantilever arm 13 and tray 126, see particularly FIGS. 9 and 11. The actuator finger 166 includes a crank-engaging portion 171 that extends laterally through the slot 169, the actuator finger 166 having its free end portion normally disposed in the path of travel of sheets X and moved thereby to a switch-energizing position during forward movement of a sheet X toward the printing position A, as shown in FIG. 9. The upper end of the adjustment bar 167 is provided with a thumb nut-equipped screw 172 that extends through a slot 173 in the partition member 170 whereby to releasably lock the adjustment bar 167 in desired set positions. It will be noted that by shifting the adjustment screw 172 upwardly or downwardly in the slot 173, the actuator finger 166 will be caused to be shifted toward or away from the printing zone A, for a purpose which will hereinafter become apparent. As shown in FIG. 12, the actuator finger 162 moves into and out of a slot 174 in the cardfeeding tray 126; and, as shown in FIG. 10, the

actuator fingers

163 and 166 are movable into and out of elongated slot 175 and 176 respectively in the top wall 2 of the base 1.

The master card or cards B used with the machine of this invention are preferably adapted to have various data typed or written thereon relative to the name of a department, firm or individual, with the name and address only of the firm or individual imprinted on a given area of the master card with spirit-responsive car bon or similar material for duplication. The sheets X are preferably imprinted with desired information intended for distribution to the individuals or firms whose names and addresses appear on the master card B. Assuming that the spirit-responsive material is imprinted on the samearea of each master card, the

guide members

129 and 130 are adjusted to align this area of the master cards with the

printing cylinders

112 and 113. The

guide members

18 and 19 are also adjusted to position the sheets X with regard to the

printing cylinders

112 and 113 so that the names and addresses will be imprinted in the desired location on the sheets X. Assuming that the motor 53 is energized, the operator places a master card on the tray 126 and slides the same downwardly until the leading edge thereof engages the stop finger 154. During this movement, the actuator finger 162 closes the switch 158, causing the solenoid 78 to be energized to operatively connect the sheet-feeding mechanism to the motor 53. Then, as a sheet X is advanced by the feeding drums 39 and feed rolls 106, the actuating finger 163 is tripped thereby to close switch 159, energizing solenoid 104 whereby to move the moistening roller 91 into engagement with the sheet X as it passes therebetween and the power-driven pressure roller 88. Further, as the sheet X engages the actuating finger 166, the switch 160 is closed thereby to energize solenoid 148, causing the stop fingers 154 to be retracted and the pressure rolls 141 to simultaneously move into operative engagement with the master card B, whereby the cardfeeding rolls 137 move the master card B toward the

printing cylinders

112 and 113 and toward engagement with the sheet X between the printing cylinders. It will be noted that adjustment of the actuator finger 166 longitudinally of the slot 169 will vary the timing of energization of the solenoid 148, so that the spirit-responsive printed matter on the master cards may be adjusted on the sheets X longitudinally of the direction of movement of the sheets X through the machine. The drive gearing for the various feeding rolls and printing cylinders is such that the

clutch elements

58 and 59 are disengaged immediately upon discharge of the master card B and printed sheet X from the machine.

Rigidly mounted to the base 1 and extending longitudinally outwardly beyond the printing zone A is a receiver 177 comprising a sheet-receiving tray 178 and a master card storage rack 179 carried by an outer end wall 180 of the tray 178. The tray 178 is provided with a guide flange 181 and a stop flange 182, the former of which is adjustable transversely of the tray 178 and the latter of which is adjustable longitudinally of the tray 178. A master card transfer mechanism 183, carried by the end wall 180, is disposed in overlying spaced relation to the bottom of the tray 178, and is adapted to receive the master cards B as they are discharged from the

printing cylinders

112 and 113. For the purpose of guiding the discharged master card B to the transfer mechanism 183 and the printed sheets toward the bottom of the tray 178, I provide a pair of discharge guide members 184 one each disposed laterally outwardly of an adjacent end of the

printing cylinders

112 and 113, see particularly FIG. 4. The guide members 184 are mounted on a horizontally disposed transverse mounting rod 185 carried at its opposite ends by the side wall 4 and end wall 139 of the cantilever arm 13 in underlying relationship to the delivery end of the card-feeding tray 126. The guide members 184 are formed to provide laterally spaced horizontal guide lips 186 and angularly downwardly projecting intervening guide lips 187. The guide members 184 are so disposed that the master cards B move thereover while the printed sheets X move thereunder during printing and discharge thereof, the guide lips 186 dircting the master cards B in a direction to be received upon the transfer mechanism 183, the printed sheets X being directed generally downwardly toward the bottom of the tray 178.

The card-receiving rack 179 comprises a transverse housing 188 which defines a platform 189 for edgewise reception of master cards B as they are received, and a sloping backplate 190 for face-to-face engagement with the first-delivered master card. Backplate 190 is provided with a flanged brace member 191. The transfer mechanism comprises a deck 192 which is secured to the housing 188 and which slopes upwardly toward the printing cylinders 112 and '113; and a grid-like transfer element 193 that is normally disposed in face-to-face engagement with the top surface of the deck 192. Portions of the transfer element extend through slots 194 in the housing 188 and are rigidly secured to a horizontally disposed shaft extending through the housing 188 transversely of the receiver, the shaft being indicated by the reference numeral 195 and being journalled in the opposite end walls of the housing 188. As shown in FIGS. 14 and 15, the transfer element 193 is movable between its normal receiving position adjacent the deck 192 and a card-stacking position in closely spaced relation to the backplate 190, and is yieldingly urged toward said normal cardreceiving position by a torsion spring 196 within the housing 188, see FIG. 1. Means for moving the transfer element 193 from its card-receiving position shown by full lines in FIG. 14 to its card-delivery or transfer position shown by dotted lines in FIG. 14, comprises a solenoid 197 secured to the brace flange 191, a coil tension spring 198 secured at one end to an armature extension 199 of the solenoid 197, a crank member 200 mounted on a stub shaft 201 that is journaled in an end wall 202 of the housing 188, and a gear segment 203 operatively connected to the crank member 200 for common rotation therewith. The outer free end of the crank member 200 is connected to the opposite end of the tension spring 198, and the gear segment 203 has meshing engagement with a cooperating pinion 204 fast on the shaft 195.

The solenoid 197 is controlled by a switch 205 mounted within the deck 192 and having an elongated actuator finger 206 that extends upwardly from the switch 205 through an opening 207 in the top wall of the deck 192. As shown in FIG. 2, the housing 188 is provided with a slot 208 for reception of the actuator finger 206. It will be noted that the top surface of the deck 192 is provided with a pair of laterally spaced cushions 209, of felt or the like, upon which the transfer element 193 rests in its normal card-receiving position.

As each master card B is discharged from the machine, it falls upon the transfer element 193 and actuator finger 206, moving the actuator finger 206 downwardly to close the switch 205, thus energizing the solenoid 197 which imparts movement to the transfer element 193 to stack the master cards B with one edge on the platform 189 and in face-to-face relationship to the backplate 190. As the card is moved to its stacked position, the actuator finger 206 is disengaged, and returns to its position shown in FIGS. 1 and 14, whereby to de-energize the solenoid 197 and permit the torsion spring 196 to return the transfer element 193 to its normal card-receiving position, As subsequent printed sheets are delivered to the tray 178 and master cards to the transfer element 193, said master cards are stacked on the platform 189 in the order in which they were introduced to the machine, thus making it easier for the operator to replace the cards in their respective file.

My invention has been thoroughly tested and found to be completely satisfactory for the accomplishment of the objectives set forth; and, while I have shown and described a commercial embodiment of my printing machine, it will be understood that the same is capable of modification without departure from the spirit and scope of the invention, as defined in the claims.
