This invention relates to sheet pull-up and registering devices adapted for association with sheet feeders, folders, or any instrumentality where the use of said devices is desirable.

One object of the invention is to provide sheet pull-up and registering devices that will efficiently and accurately register relatively thin sheets such as Bible stock or the like.

Another object of the invention is to provide devices that support the leading edge of the sheet and operate through frictional engagement therewith, to pull it up to the sheet registering devices without crumpling or tearing the sheet.

A further object of the invention is to provide means for accurately registering the sheet after it engages front stops and is pulled up to said means by the pull-up devices.

Another object of the invention is to provid sheet pull-up and registering devices that are adjustable to accommodate sheets of various sizes and wherein the frictional engagement of the pull-up devices with the sheet may lie-varied as desired.

Other objects of the invention will appear as r the following description thereof proceeds.

In order to more clearly understand the invention reference may be had to the accompanying drawings which illustrate one embodiment of the inventive idea and wherein:

Fig. 9 is a fragmentary side elevation, partly in section, of the sheet pull-up and registering devices, showing the sheet engaged with front stops moved rearwardly of the sheet registering device;

and Y Fig. 10 is a view similar to Fig. 9, showing the front stops moved forwardly of the sheet registering device and the sheet pulled up thereto.

Referring to the drawings, wherein like reference characters designate like parts throughout the several views, 5 indicates a suitable source of power preferably comprised by an electric motor the armature shaft 6 of which has fixed thereon a pulley 7. Passing around the pulley 'l is a belt 8 that also passes around a pulley 9 fixed on one end of a main power shaft 10 journaled in suitable bearings on the side frames (not shown) of a paper folding machine.

Fixed on the opposite end of the shaft 10 is a pinion 11 that meshes with an idler gear 12 which in turn meshes with an idler gear 13 that V framework and around rollers 20 carried on arms 21. The arms 21 are fixed on a rock shaft 22 journaled in suitable bearings on the machine framework and said arms carry weights 23 which normally act to depress the arms 21' and the rollers 20 so as to take up the slack in the tapes 18.

The sheets are fed from any suitable source of supply to the feed roller 17 and tapes 18 and the latter carry the successive sheets forward from a feed boardl? to movable front stops hereinafter described. As herein shown, a drop rollor mechanism is employed in conjunction with the feed roller 17 and said mechanism comprises and is operated by the following instrumentalities. Fixed on the main power shaft 1c is a pinion 24 that meshes with an idler pinion 25 journaled on one of the side frames of the machine. This idler pinion 25 meshes with a large gear 26 fixed on one end of a driven shaft 27 that is journaled in suitable hearings on the machine framework. The shaft 27 has fixed thereon adjacent the gear 26,12. cam 28, and straddling said shaft between the gear 26 and the cam 28, we is a fork 29 formed on one end of a link 30 which carries a roller 31 that is spring-pressed into engagement with the cam 28 by means to be presently described. The link 30 is pivotally connected at 31 with an arm 32 that is fixed on a rockshaft 33 journaled in suitable bearings on the machine framework. Fixed on the rockshaft 33 are arms 34 that carry a rod 35 on which are mounted drop-rollers 36 that are raised by the cam 28 when the sheet is fed between the feed 3 ers 36 are then lowered through the medium of an arm 37 that is fixed on the rockshaft 33 and operated rearwardly by a spring-pressed rod 38,

one end of which is pivotally connected to said arm. The opposite end of the rod 38 extends through a suitable opening formed in a stud 39 on the machine framework. Carried on the rod 38 between a collar 40 thereon and the stud 39, is

a coil spring 41 which is compressed when the drop-rollers are raised and thereafter acts to lower said rollers as described. The sheet is then fed forwardly to the front stops, to-be acted on by pull-up, registering, and, folding devices hereinaftr described.

Thefront stops are preferably comprised by and operated through the medium of the following instrumentalities. Fixed on the driven shaft 27 is a bevel gear 42 which meshes-with a bevel gear 43 that is fixed on one end of a shaft 44 journaled in suitable bearings on the machine and extending longitudinally thereof substantially at right angles to'the shaft 27. Fixed on the opposite end of the shaft 44 is a bevel gear 45 that meshes with a bevel gear 46 rigidly secured on a shaft 47 extending transversely of the machine and journaled in suitable bearings on the framework thereof. This shaft 47 has fixed on one end thereof, a cam 48 that engages a spring-pressed roller 49 carried on one arm 50 of a double bell crank lever pivoted at 51 on a stationary part of the machine. A second arm 52 of this bell crank lever has pivotally connected therewith one end of arod 53 the opposite end of which extends through a suitable opening in a stud 54 carried on one of the side frames of the machine. 'Carried on the rod 53 is a coilspring 55 one end of which abuts against the stud ,54, the opposite end of said spring abutting a collar 56 fixed on the rod 53. It will thus appear that the bell crank 50, 52 is cam operated in one direction and spring-operated in the opposite direction so that the roller 49 always follows the cam 48. A third arm 57 of the double bell crank lever has pivotally connected therewith one end of a link 58 the opposite end of which is pivotally connected with an arm 59' that is fixed on one extremity of a rockshaft 60 extending transversely of the machine and journaled in suitable bearings on the side frames thereof. Fixed on the rockshaft 60 adjacent opposite ends thereof are arms 61 the free ends of which are pivotally connected at 62 with extensions 63 of U-shaped brackets 64. The brackets 64 are secured to, or formed integrally with, bars 65 that are reciprocated on rollers 66 journaled in suitable bearings on the side frames of the machine.

Mounted on the bars 65 for reciprocating movement therewith and adjustment longitudinally thereof, are brackets 67 and secured to said brackets is a bar 68 that extends transversely of the machine and carries the front stops 69. In the operation of the machine, the front stops 69 move rearwardly to be engaged by-the leading edge of the sheet, whereupon said stops are moved forwardly and the drop rollers 36 are raised, to provide for the operation of the pull-up and sheet registering devices on the first sheet and the feeding of the next sheet forwardly from the feed board 17'.v This rearward and forward movement of the front stops 69 is effected by the described connections therefor with the bell crank 50, 52, 57 that is rocked by the cam 48 and the spring 55. In accordance. with the present invention, the operative position of the stops 69 may be changed as desired to accommodate sheets of different sizes and this is preferably effected through the medium 'of the following instrumentalities.

Journaled in suitable bearings on the brackets 64 is a shaft 70 having secured on one end thereof a crank handle 71 for turning said shaft. Fixed on the shaft 70 between the arms of the brackets 64 are worm gears 72 that mesh with worm gears 73 fixed on screw shafts 74 extending at right angles to the shaft 70 and threaded through suitable screw threaded openings in the brackets 67. It will thus appear, that when the shaft 70 is rotated by the crank handle 71, the brackets 67 will slide along the bars 65 in a direction corresponding-with thedirection of rotation of the shaft 70, whereupon the bar 68 and the stops 69 will likewise be moved to change theposition of the latter in accordance with the size of the particular sheet that it is desired to handle in the machine.

After the stops 69 are moved rearwardly, the pull-up devices above referred to act on the sheet to pull it up to the sheet registering devices. In the preferred embodiment of the invention illustrated in the drawings, two-.pull-up and sheet registering devices are employed, the same'being adjustable toward and away from each other to accommodate sheets of various sizes and each carrying one of the sheet registering devices. The.construction' and operation of the two sheet pull-up and registering devices, together with the adjusting mechanisms therefore, are identical and it is therefore only necessary to describe one of the same. The pull-up devices preferably compriseand are operated through the medium of the following instrumentalities. Fixed on the shaft 47 is a cam 75 between which and the cam 48 is arranged a link 76 having a forked end 77 engaged over the shaft 47. The opposite end of the link 76 is pivotally connected with one arm 78 of a bell crank that is rigidly secured on a rockshaft 79 extending'transversely of the machine and Journaled in suitable hearings on the framework thereof. The other arm 80 of this bell crank has pivotally connected therewith one end of a rod 81 the opposite end of which extends through a suitable opening in a stud 82 carried by one of the side frames of the machine. Mounted on the rod 81 between a collar 83 thereon and the stud 82 is' a coil spring 84. The link 76 carries a roller 85 that is caused to follow the cam 75 by the spring 84. It will thus appear that the rockshaft 79 will be cam operated in one direction and spring-operated in the opposite direction as the shaft 47 is rotated through the described driving connections therefor with the shaft 27.

Fixed on the side frames of the machine and extending transversely thereof is a bar 86 arranged in substantially parallel relation with the rockshaft .79. Mounted on the bar 86 and the rockshaft 79; for adjustment laterally of the machine, is a bracket 87 having a dove-tailed slot 88 and spaced apertured ears 89. The slotted portion 88 of the bracket 87 is slidably engaged over beveled edges 90 of the bar 86 and the rockshaft 79 extends through the apertures in the ears 89 and is provided with a longitudinal keyway 91 as clearly shown in Fig. 1 of the drawings. Mounted on the rockshaft 79 between the ears 89 and the bracket 87 is an arm 92 having a key or pin 93 engaged in the keyway 91 of the rockshaft 79. Attached to the arm 92 is one end of a connection 94 the opposite end of which is secured to an arm 95 of a bell crank 96 mounted on the bracket 87 in suitable openings formed in arm 134 of an L-shaped time: indicated spaced ears 9'! of said bracket (Figs. 1 and '1).

The other arm 98 of the bell cranklever 96 is.

' is provided-with an adjusting screw 106 that engages the cross bar 105 and can be turned tdraise or lower the bar 104 about the pivot therefor provided by the bell crank 96. The other arm 107 of the bell crank 103 has attached thereto one end of a connection 108 the opposite end of which is secured to the arm 95 of the bell crank 96. It will thus appear that rocking motion of the shaft '79 acts through the connections therefor with the bar 100 to raise and lower the latter at certain intervals during the operation of the machine. This up and down movement of the bar 100 is utilized to intermittently raise a roller 109 which in its operativeor lowermost position acts to hold the sheet in frictional engagement with the pull-up device proper. The roller 109 is iournaled on the lower end of a slide 110 (Fig. 2) that is providedat' its upper end with a plate 111 carrying at one side thereof an adjusting screw 112 that engages the bar 100 and regulates the amount of upward movement imparted thereby to said roller. The slide 110 is guided on a brackat 113 carried by the bar 104, said slide having a slot 114 through which projects pins 115 and 116 that are secured to the bracket 113 and act to retain the slide 110 thereon as clearly shown in Fig. 2 of the drawings. The plate 111 also carries an adjusting screw 11'! having connected therewith one end of a coil spring 113, the opposite end of which is connected with the pin 116. The spring 118 acts to lower the roller 109 in engagement with the sheet, the screw 117 being adjustable to vary the tension of the spring 113 in ac-- cordance with the adjustment of the screw 112.

The bracket 113 is provided with a dove-tail slot 119 engaged over the beveled edges 120 of a guide plate 121 secured to the bar 194. A guide block 122 carried by the guide plate 121 is ad= justable along the latter and may be secured in any desired position of adjustment by a set screw 123. Journaled in a suitable bearing on the guide block 122 is a screw shaft 121 that isthreaded in a boss 125 formed on the bracket 113.

It will thus appear, that in addition to the adjustment of the bracket 113 and roller 199 provided by the guide block 122, said bracket and roller may be further and more accurately adjusted forwardly or rearwardly as desired by rotating the screw 124 in the proper direction.

The pull-up device proper is preferably carried by a horizontally extending frame-like'bracket 126 provided at one end with upwardly bent arms 12? secured to the front face of the bracket 87 as by machine screws 128. The bracket 126 is further provided with opposed parallel guide slots 129 in which is slidably mounted a plate 130 provided at one end with a slot 131 extending longitudinally thereof. During the operation of the machine, this plate 130 is reciprocated in the guide slots 129 by the bar 68 which for this purposeis provided with a flange 132 having a slot 133 therein through which extends a vertical broadlyat 135. The other or horizontal arm 136 of said bracket is secured to the plate 130 by a bolt 13'! that extends through the slot 131 and by means of which the plate 130 may beadiusted rearwardly or forwardly relative to the bar 68 to accommodate sheets of various sizes. on the end of the plate opposite that provided with the slot 131, is mounted a pull-up member which is preferably comprised by a friction pad 138 of leather or suitable material that is secured in any suitable manner, as by stitching 139 (Fig. 6), to 11.

plate 140. The plate 140 is provided in one end thereof with an opening 141 for a set screw 142 which may be secured in any one of a series of screw threaded openings 143 formed in the end of the plate 130 carrying the pad 138. It'will thus appear that the pad 138, through the medium of the set screw 142 and threaded openings 143, may be adjusted to any desired position longitudinally of the plate 130. As the sheet is fed forwardly by the conveyor tapes 18, it passes over and is supported by the pad 138 until the leading edge of the sheet engages the front stops 69. At this time, the roller 109, through the operating connections therefor with the rock shaft '79,

lowers into engagement with the sheet on the pad 138, whereupon the front stops 69 and the bar 68 are moved forwardly carrying therewith the plate 130. The sheet, being frictionally engaged between the roller 109 and the pad 133, is thus pulled up by the latter to the sheet registering devices each of which is mounted on one of the brackets 126 and preferably comprises the following devices.

Two spaced pairs of springmetal clips 144 (Figs. 3, 4, 5, 7, 9- and 10) have outwardly bent ends 145 into which the leading edge of the sheet is pulled by the pull-up device 138. As said edge of the sheet advances between the arms of the spring clips 144, it engages points or lugs 145' of a sheet registering bar 146 to the opposite extremities of which are secured, as by set screws 147, the upwardly bent forward ends 1480f the spring clips 144 (Fig. 3). The bent up forward ends 148 of said clips are preferably received in formed in a bracket 153 that is slidably mounted on one side of the bracket 126, the bar 151 being retained on bracket 153 as by plates 154 and set screws 155. The bracket 153 is provided on its under side with a beveled tenon 156 that is slidably mounted on the bracket 126 in a dovetail slot 157 formed on one side of said bracket at the top thereof. Formed in the tenon 156 is a slot 158 for a leaf spring 159 that is secured to the bracket 153 by a screw 160 and frictionally engages the bottom of the dovetail slot 15?. The bracket 153 is provided with a boss 161 through which is threaded a set screw 162 adapted to engage the bracket 126 to hold the bracket 153 and the sheet registering bar 146 in any desired position of adjustment on the bracket 126. Rotatably mounted in a boss 162' of the bracket 153 is a screw shaft 163 provided at one end with a turning knob 164. This screw shaft 163 is threaded through a suitable opening in the end of an arm 165 of a small bracket 166 that is will thus appear, that by-rotating the screw shaft 163, a further and more accurate adjustment of the sheet registering device 146 may be obtained if desired.

Through the medium of the screws 106, 112 and 117, the roller 109 and the friction pad 138 may be adjusted relatively to obtain frictional engagement between these elements that is sufficient to pull the sheet up against the sheet registering devices and at the same time allow for slippage between said elements in the event one side of the sheet is pulled up against one sheet registering device before the oppositeside of the sheet is pulled up to the other sheet registering device. For example, if a sheet is fed to the sheet registering devices out of alignment therewith, the leading edge of the sheet will engage one sheet registering device before it engages the other sheet registering device. In this event, the roller 109 and pad 138 at the side of the sheet engaged with the first sheet registering device, will slide relatively to the sheet to prevent crumpling or tearing thereof, and the opposite side of the sheet will be acted on by the corresponding pull-up device until the leading edge of the sheet is brought up against both of the sheet registering devices. This is illustrated diagrammatically in Fig. 4 by dotted lines which show, for example,

the position of the leading edge of the sheet in and out of alignment respectively with the side registering devices. After the sheet has been properly registered, the roller 109, through the connections therefor with'the rockshaft 79, is lifted, at which time thesheet may be folded by any suitable means for this purpose.-

The folding means herein shown preferably comprises and is operated by the following instrumentalities. Fixed on the shaft 27 is a cam 168 that engages a roller 169 journaled on the free end of-an arm 170 that is fixed on one extremity of a rockshaft 171 extending transversely of the machine and journaled insuitable hearings on the side frames thereof. Rigidly secured on the rockshaft 171 adjacent opposite ends thereof, are curved arms 172 that carry a folding knife 173 which, during the operation of the machine, is raised and lowered by the arm 170 through the medium of the cam 168 and a spring-pressed rod 174. One end of this rod 174 is pivotally connected with the arm 170, the opposite end of said rod extending loosely through a suitable opening in a stud 175' carried by one of the side frames of the machine. Mounted on the rod 174 between a collar 176 thereon and the stud 175, is a coil spring 175 which is compressed when the high part of the cam 168 engages the roller 169 to lift the folding blade 173. After the sheet has been registered as above described, the low part of the cam engages the roller 169 whereupon the spring 175 causes said roller to follow the cam and depress the arm 170 which then lowers the folding blade 173. As the folding blade 173 descends, it engages the registered sheet between the bight of a pair of driven folding rollers 177. These rollers 177 deliver the folded sheets onto conveyor tapes 188 that carry the sheet to a second folding mechanism or to any desired point of delivery for the sheets. The folding rollers 177 and the tapes 188 are arranged and operated in a well known manner and since they form no part of the present invention it is not necessary to describe the same in detail. I

The pull-up and sheet registering devices, as previously mentioned, are relatively adjustable laterally of the machine to accommodate various sizes of sheets. For this purpose, the bar 86 is provided at the ends thereof with brackets 189 in which are journaled screw shafts 190 the outer ends of which carry crank handles 191. These screw shafts 190 are threaded through bosses 192 on the brackets 87, and itwili thus appear, that by turning said screw shafts, the brackets 87 and the various parts of the sheet pull-up and registering devices can be adjusted laterally of the machine as desired.

The operation of the sheet pull-up and registering devices will be clearly understood from the foregoing and may be briefly summarized as follows. After the sheet has been fed between the feed roller 17 and the drop rollers 86, the latter descend to engage the sheet with said feed roller which, through the medium of the tapes 18, then advances the sheet so that the leading edge thereof passes over the friction pads 138 and under the rollers 109 which at this time are separated by raising movement of the bar 100. The rollers 109 are then lowered into engagement with the sheet, whereupon the front stops 69 are moved forwardly carrying with them the plates 130 and the friction pads 138. Through the frictional engagement between the rollers 109 and the pads 138, the sheet is advanced or pulled up by the plates 130 until the leading edge of the sheet passes between the opposed arms of the spring clips 144 and engages the sheet registering bars 146. After the sheet is properly registered against the bars 146, the rollers 109 are lifted by the bar 100, whereupon the folder blade 178 descends and folds the sheet in the bight of the rollers 177 which then deliver the folded sheet to the tapes 188.

It will appear from the foregoing that mechanism embodying the present invention will pull and straighten up the sheet without danger of tearing the same, and that through thevarious adjustments provided for the mechanisms, an extremely accurate register of the sheet is obtained. Moreover, the pull-up devices for the sheets in addition to their primary function, also act to support the leading edge of the sheet prior to acting on the same, which is a desirable function in the case of relatively thin sheets that otherwise" would require independent supporting means therefor.

While the invention has been described particularly as respects application thereof to a knife folding machine, it will of course be understood that the invention may be employed in other types of folding machines, or with various ity where the use of pull-up and sheet registering devices is desirable. Moreover, while one embodiment of the invention has been illustrated in the accompanying drawings, it is to be expressly understood that the invention is not limited thereto or otherwise than by the terms of the appended claims.
