11 .Claims. (Cl. 2712.4)

This invention relates to strip feeding apparatus and methods, and more particularly to such apparatus and methods achieving a compound motion of the strip.

While not so limited, the invention is well adapated for use with addressograph machines and the like, wherein a strip of series connected detachable record forms are fed to and from an imprinting station.

T he object of the invention is to improve the construc tion as well as the means and mode of operation of strip feeding devices, whereby such devices-may not only be economically manufactured, but will be strong-and sturdy in construction, of relatively compact nature, adaptable to a wide range of usage, but having relatively few parts and be unlikely to get out of repair.

It is an object of the invention to enable plural column listing upon a single record form.

A further object of the invention is to provide for motion of the record strip in a lateral as well as a longitudinal sense.

Another object of the invention. is to introduce a principle of dual feed in machines of the kind described wherein different parts of a manifold strip assembly may be advanced dilferent amounts, makingit possible, for example, to make efiicient use of a summary record strip.

A further object of the invention is to achieve in a machine of the kind described a compound motion ofthe strip involving a differential advance of different parts of the strip in a longitudinal sense plus lateral columnar adjustment of the strip assembly as a unit.

Still another object of the invention is to provide for columnar adjustment of the strip automatically and as a part of the machine operation.

A still further object of the invention is to present dual feed mechanisms independently operable as a part of the machine operation.

Still another object of the invention is to introduce a new method of strip feeding, substantially as herein disclosed.

A further object of the invention is to provide a strip feeding device possessing the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein disclosed.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described or illustrated in the accompanying drawings, or their equivalents.

Referring to the accompanying drawings, wherein is shown one but obviously not necessarily the only form of embodiment of the invention,

Like parts are indicated by similar characters of reference throughout the several views.

In the illustrated instance, the strip feeding apparatus and method of the present invention are disclosed as an attachment of an addressograph machine. The feeding apparatus is operable upon a manifold strip assembly made up of a part 20 and another part 21 (Fig. 1). In the present strip assembly, the part 20 thereof includes series connected check forms 22, with offset stub porture on the addressograph machine which provides a support therefor in the form of a table 28. As seen also in Fig. 4, brackets 29 are mounted on the table 2 8 and support a pack holder device 31 having separate compartments for respective supply packs, in which the

parts

20 and 21 are placed in the machine for feeding. The free ends of the

parts

29 and 21 of the strip assembly project out of the holder 31 toward what may be considered the front of the machine, or the left hand end thereof as viewed in Fig. 4. Beyond the holder 31, the separate .parts of the strip achieve a superposed, adjacent relation, resting on a bridge-like member 32. The member 32 inclines downwardly toward the table 28, and, at the lower end thereof, the strip assembly separates again into its component parts, passing over

respective feeding devices

41 and 38. The strip material comprising the manifold strip assembly is marginally perforated, and the feed- 3 1

ing devices

41 and 38 include pin wheels which engage the marginal perforations in the strips for positive feeding thereof and for the maintaining of accurate registration.

Beyond the

feeding devices

41 and 38 the strip assembly resumes its unitary form and passes in a generally reverse direction over the table 28 toward the rear of the machine, or the right hand end thereof as viewed in Fig. 4. About mid way of its travel over the table 28, the strip assembly passes through the addressograph imprinting station, indicated diagrammatically herein at 37. As will be described, by intermittent feeding increments imparted to the strip assembly, successive record forms are brought to the imprinting station, are there imprinted upon, and then are moved on for separation or for refolding. Toward the end of the table 28, the strip assembly again is separated into its

parts

20 and 21, the part 20 passing over a feeding device 34 and being directed thereby into a refold compartment 39, and the part 21 passing over a feeding device 33 and being directed thereby into a refold compartment 42.

'It may thus be considered that there is associated with the strip part 20 a front feeding device 41 and a rear feeding device 34 and that there is associated with the strip part 21 a front feeding device 38 and a rear feeding device 33. The

separate strip parts

20 and 21 may thus be advanced independently of one another or in unison and they may, moreover, be advanced differentially, that is, in increments or steps of differing lengths.

Considering the

feeding devices

33 and 34 and 38 and 41 in greater detail, and referring to Fig. 6, the

rear devices

33 and 34 respectively include

transverse shafts

43 and 44. On the shaft 43 pin wheels 35 are detachably secured in spaced apart relation with strip sup-porting discs 45 therebetween. The shaft 44 has pin wheels 36 detachably secured thereto and in a spaced relation different from that of the wheels 35, supporting discs 46 like the discs 45 being mounted on the shaft 44 between the pin Wheels 36.

The front feeding device 38 (Fig. 2) includes a pair of pin wheels 47 complementary to the pin wheels 35, detachably secured on a shaft 48. The feeding device 41 includes pin wheels 49, complementary to the pin wheels 36, and detachably secured to a shaft 51. The pin wheels 47 and the pin wheels 49 are respectively surmounted by paper or strip guides 52 and 53.

Referring to Fig. 4, forwardly projecting brackets 54, attached to the addressograph machine, support a transverse frame member 55 which provides a mounting for the front

pin wheel shafts

48 and 51. The

rear shafts

43 and 44 have their one ends received in

respective bearings

56 and 57 in a frame supported bracket 58, while the opposite end of the

shafts

43 and 44 are received in respective frame supported bearings 59 and 61.

With respect to the

front feeding devices

38 and 41, these are mounted in a projecting frame 62 fastened to the member 55. Frame supported bearing

housings

63 and 64 receive the opposite ends of the pin wheel shafts.

48 and 51, the housing member 63 containing

bearings

65 and 66 corresponding to the above mentioned bearings 59 and 61, and shown in Fig. 8, and the housing member 64 containing bearing elements (not shown) corresponding to the

bearings

56 and 57 aforementioned. The bearing

elements

56 and 57 and the corresponding bearing element in the housing member 64 are of identical construction. Thus, as seen in Figs. 6 and 7, the bearings are cylindrical and include needle bearings 67 and ball bushings 68. The several shafts have a direct mounting in the bearings 67 and 68 and project through and beyond such bearings into respective air cylinders or dash pots 69.

The

several bearings

59, 61, 65 and 66 also are identical and are generally the same as the

bearings

56 and 57. Thus, as shown in Fig. 8, the bearing 66 includes needle bearings 70 and a ball bushing 71. In this instance,

however, there is interposed between the needle bearing 70 and the ball bushing 71 one end of a sleeve 72. The other end of the sleeve 72 is pinned to a shaft 73. The shaft 73 projects out of the sleeve 72 and is received in a bushing 74 with the outer ends of the shaft 73 and bushing 74 being interconnected through a variable member 75. A frame supported bearing 76 is aligned with the bearing 66 and cooperates therewith in supporting the assembly comprising the sleeve 72, shaft 73 and sleeve 74 for rotary motion relatively to the frame 62.

The shaft 51 extends through and beyond the bearing 66 into the sleeve 72 where a key 77 thereon is slidingly received in a groove 78 in the sleeve. The shaft 51 accordingly is connected to the sleeve 72 for unison rotary but relative axial motion.

A sleeve 79 is similarly installed between the bearing 65 and a frame mounted bearing 81. The shaft 48 is received in and connected to the sleeve 79 in the same manner that the shaft 51 is received in and connected to the sleeve 72. Further, the sleeve 79 is connected to a shaft '82 and the latter is engaged with a sleeve 83 through a variable 84, all in the same manner as described above with respect to sleeve 72 and its associated parts.

The opposite ends of the

shafts

51 and 48 extend through the bearing housing 64 into another housing 85 containing dash pot air cylinders corresponding to the cylinders 69 of Fig. 6. The variables 75 and 84 are not disclosed in detail herein, it being understood that these devices perform a known function in permitting the

shafts

48 and 51 to be rotatively adjusted manually, independently of such rotary driving mechanism as may be provided therefor.

The bearings 59 and 61, associated with the left hand end of the

shafts

43 and 44, as viewed in Fig. 6, are as before described like the

bearings

65 and 66. There is, moreover, a sleeve 86 associated with the bearing 59 and a sleeve 87 associated with the bearing 61 corresponding to the

sleeves

72 and 79. The

sleeves

86 and 87 receive the

respective shafts

43 and 44 for unison rotary and relative axial motion, also in the same manner that the

shafts

48 and 51 are received in the

sleeves

72 and 79. Further, the

sleeves

86 and 87 are similarly mounted and actuated. Referring to Fig. 12, where sleeve 86 is shown by way of example, the outer end thereof is pinned to a stub shaft 88 which extends through a bushing 89 installed in a frame mounted bearing 91. The outer end of the shaft 88 and of the bushing 89 are interconnected by a tube 92 forming part of a variable like the variables 84 and 75 previously described. The bushing 89 is formed with a gear 93, serving a purpose hereinafter to be described.

The shaft 43 and the shaft 48 are interconnected for unison rotary motion, and the

shafts

44 and 51 are similarly interconnected. Thus, the aforementioned gear 93 meshes with a gear 94 (Fig. 7) mounted in a frame supported bearing 95, and the corresponding gear (not shown) associated with sleeve 87 meshes with a gear 96 in a frame supported bearing 97. The gear 94 is on a shaft 98, also carrying a mitre gear 99. The gear 99 meshe with a similar gear 101 on a shaft 102, such shaft extending alongside the strip feeding apparatus and having a bearing in housings 103. The gear 96 is on a shaft 104, also carrying a mitre gear 105. The gear 105 meshes with a similar gear 106 on a shaft 107 which extends in parallel relation to the shaft 102 and is similarly supported.

The shafts 102 and 1.07 extend toward the front of the machine and have their ends received in

respective bearing housings

108 and 109. Extending through and beyond housing 108, the shaft 102 has a mitre gear 110 thereon meshing with a similar gear 111 on the bushing 83. Similarly the shaft 107 extends through housing 108 and an offset extension 107a thereof is geared to a mitre gear 112 meshing with a like gear 113 on the bushing 74. According to the construction and arrangement shaft 43 of feeding device 33 and of shaft 48 of feeding device 38. Also, rotation of the gear corresponding to gear 93, and associated with sleeve 87, willresult in a corresponding and simultaneous rotation of the shaft 44 of feeding device 34 and shaft 51 of feeding device 41.

The actuation of such gears is effected by individual motorized units contained in respective housings 114 and 115 (Fig. 2), with the unit of housing 114 being shown in some detail in Fig. 7. The construction and mode of operation of the motorized units is substantially the same as those disclosed in Davidson et al. application, .Serial No. 62,798, filed December 1, 1948, now Patent No. 2,700,334,-for Strip Feeding Device. Such mechanism will accordingly be only briefly described herein. Thus, and referring to the unit shown in Fig. 7 as operative upon gear 93, the gear 93 meshes with a gear116 on a shaft 117 in the housing 114. Also on the shaft 117 is a gear 118 meshing with a large gear 119 on ahousing supported shaft 121. The shaft 121 extends through the housing 114 into driven relationship with a motor 122. Also on the shaft 121 is a disc123, sometimes called a program disc, the circumferential spacing of notches 124 on its periphery determining the length of successive steps of advancement of the record strips.

In the operation of the machine, the direction of rotation of the motor 122 is clockwise as viewed in Fig. 7.

Rotation of the disc 123 in this direction normally is prevented by a pawl 125 which engages one of the .teeth 124 of the disc 123. The pawl 125 is released or disabled by a finger 126 on a lever 127, the movement of which is controlled by an electromagnetic device 128. Energizing of the device 128 results in a. counter .clockwise rocking motion of the lever 127 and a releasing of the pawl 125. In moving to releasing position, the pawl 125 rocks in a clockwise direction and acts upon a plunger 129 of a switch 131 which is in a circuit with the motor 122. Thus the release of the pawl 125 serves also to initiate operation of the motor 122 so that as substantially concomitant operations the pawl 125 is moved out of engagement with a tooth 124 and the motor 122 is energized to rotate shaft 121 and associated parts leading to gear 93 and gear 94. The energizing of the electro- .magnet 128 may be of momentary duration, and, once released, the pawl 125 is free to return tocontact with the periphery of the disc 123 and will reengage the first encountered notch 124 thereon thus interrupting the feeding operation.

It will be understood that the motorized device above described is effective upon the

feeding devices

33 and 38, and that another and substantially identical motorized device is provided for operating the

feeding devices

34 and 41. The second said device, as noted, is contained in housing 115 and is made up ofparts like those above described, including a separate and individual motor 132 (Fig. 2). Referring to Fig. 13 of the drawings, the

electromagnet 128 of the motorized units, the switches 131 thereof and the

motors

122 and 132 are connected in an electrical circuit 133 controlled by a switch 134. Thus, when the switch 134 is closed the electromagnets 128 are energized and a strip feeding operation ensues as above described. When the switch 134 opens, the electromagnets' 128 are deenergized and the strip feeding operation is interrupted, as the pawls 125 return to normal positions on the periphery of the respective'discs 123. Also included in each motorized unit, and indicated generally in Fig. 13 at 135, is a delay means operable to hold the switch 131 closed until the disc 123 has advanced at least the distance of one notch.

.The switch 134 is shown in Fig. 11 as operated by a cam 136 mounted on a shaft 137 and ,having a single actuating formation 138 on its periphery. Considering the switch 134 to be normally open, the illustrated construction and arrangement of parts is such as to cause the switch-134 momentarily to'close once for each revolution of the shaft 137. The latter is mounted in a frame member 139 and carries a gear 141 meshing with a gear 142 on a shaft 143. The shaft 143 is the principal clutch shaft of the addressograph machine. For each revolution thereof the machine completes a cycle of operation, including an actuation of the imprinting mechanism. The gear 141 is approximately twice as large as the gear 142. Thus, since twocomplete revolutions of the shaft 143 and gear 142 will be required to effect one complete revolution of the shaft 137 and gear 141, it will be understood that the switch 134 is closed once for each two revolutions of the clutch shaft 143, This means, therefore, that feeding of the record strips in the instant illustrated embodiment of the invention is accomplished on every other or alternate imprinting operation.

Also in accordance with the instant embodiment of the invention, it is proposed to advance the

parts

20 and 21 of the record strips differentially. There will accordingly be a difference in spacing between the notches onvthe. disc 123 of the one motorized unit as compared with the spacing between notches on the corresponding disc of the other unit. Should no diiferential feeding of parts of the strips be required, both parts of the strip could be attached to onengaged by a corresponding pair of feeding devices, with the other pair of feeding devices made ineffective by temporarily disabling the associated motorized unit. In this connection, and as shown in Fig. 13, there is associated with each electromagnet 128 an individual disabling switch 144. The elements 145 and 146, in the diagram of Fig. 13, represent safety switches of various kinds.

Turning now to a consideration of the means for shifting the feeding devices laterally for plural column listing, as seen in Figs. 6 and 14 the

shafts

43 and 44 are interconnected by a shift member 147 which connects the

shafts

43 and 44 for unison motion in a lateral sense but permits relative rotation thereof. One end of the member 147 is connected by a link 148 to an arm 149 on a shaft 151. The latter extends in a direction parallel to the longitudinal axis of the machine from the rear thereof to the front and at its far end is connected to another lever or arm 152. The lever 152 is connected by a link 153 to another shift member154 which is constructed and arranged like the member 147 and serves to interconnect the

shafts

48 and 51 in the same manner that member 147

interconnects shafts

43 and 44. It is thus seen that the

several shafts

43, 44, 48 and 51 are so interconnected that motion of one set of shafts in a lateral sense is partaken of by the other set of shafts, with the motion of both pairs of shafts being in the same direction.

The described lateral motion of the feed shaft is accomplished from the aforesaid. clutch shaft 143. This shaft has on it a gear 155. Meshing with the gear 155 is a gear 156 on one end of a cylindrical body 157 formed with a circumferential cam groove 158. An actuating lever 159 is pivoted intermediate its ends at 161 and carries at its one end a pin 162 received in the groove 158. In response to rotation of the body 157, the lever 159 is moved in an oscillatory sense as the pin 162 follows the groove 158. The groove 158, in the present instance, is so formed as to cause the lever 159 to move in one direction during one revolution of the shaft 143 and then to return in the opposite direction during the next succeeding revolution of the shaft 143.

The opposite end of the lever 159 has an elongated slot 163 therein receiving a vertical pin 164. The pin 164 is interconnected by a link 165 with the similar pin 166 set in the shift link 147. As will be understood, the described oscillatory motion of the lever 159 is effective through the link 165 to move the shift members 147 and'154 bodily in a lateral sense.

An adjustable clamp 167 is mounted on the lever 159, in a position overlying the slot 163. The member 167 may be adjusted to vary the position of the pin 164 with respect to lever 159 to thereby vary the degree or amount of movement of the shift lever 147.

The air cylinders 69 (Fig. 6) serve a purpose in damping the lateral shifting motion of the feed shaft. Also assisting in this function is a dash pot 169 (Figs. 3 and 14), the cylinder of which is fastened to the frame and the piston of which is connected to link 153.

The

pin wheels

47 and 49 at the front of the machine are interconnected by tie members 171. Pivotally adjustable on the tie members 171 are side arms 172 carrying a deflector roller 173 which directs one part of the strip out of the path of the other.

It is thought that the operation of the strip feeding apparatus will be largely self evident from the foregoing description. Briefly, however, one cycle of addressograph machine operation will find the record strip assembly extending through the printing zone 37 (Fig. 4) with the stub 23 of a check form in printing position. As this cycle of operation is completed and the stub 23 imprinted, at the start of the next succeeding operation, the shifting lever 159 is actuated to move the feeding devices laterally whereby to move the stub 23 out of printing position and to move the check form proper 22 into printing position. The imprint, occurring near the end of the cycle, accordingly is made upon the check 22. Now as the machine enters a following cycle the record strip assembly is advanced in a longitudinal sense, and, at the same time, the shifting lever 159 moves in a reverse direction to that previously effected and moves the feeding devices back to their original position. The close of this cycle accordingly finds the check stub of the next succeeding record form in imprinting position, and the imprinting feeding and shifting operations continue as above. The longitudinal feeding of the record strip assembly occurs, as before noted, on every other cycle of operation. Further, the

strip parts

20 and 21 are fed different amounts, it being unnecessary with respect to the summary strip 27 to allow space for a heading or other material which may appear in the check forms. It will be understood that the method and apparatus of the present invention is applicable generally to plural column listing and is not limited to work upon record forms of any particular kind or use.

From the above description it. will be apparent that there is thus provided a device of the character dedescribed possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect.
