SLIP-SHEETING MACHINE.
Specification of Letters Patent.
Patented Apr. 28, 1914.
To all whom it may concern:
Be it known that I, HOWARD K. KING, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a new and useful Slip-Sheetin Machine, of which the following is a speci cation.
My invention relates to improvements in means for separating slip sheets from between printed sheets. 1
The object of the invention is to provide improved means for automatically separatin and delivering into different piles the printed sheets and intervening slip sheets.
As is well known, the practice in connection with color printing, especially by magazine publishers, is to interpose a blank slip sheet between the printed sheets to prevent smearing or transferring of the colors.
Where very large editions are printed the separation and removal of the slip sheets from the printed sheets, before the latter are folded and bound, becomes quite a serious problem and the object of the pres ent invention is to provide means for automatioally accomplishing this work with speed and accuracy.
The invention comprises means. whereby the slip sheets are'diverted to one pile, while the printed sheets are diverted to another pile, irrespective of the order in which the said sheets are found. That is to say, even in case two slip sheets are found together they still will be diverted to their respective pile.
The invention comprises calipering means, whereby advantage is taken of the diiference in thickness between the prints sheet and the slip sheet, so that certain mechanism is set in operation depending entirely upon the thickness of the sheet passing through the calipcring device.
The invention comprises switchin or (iiverting moans controlled by said mec ianism.
The invention also comprises improvements in automatic table actuation.
The invention also comprises automatic switching means, adapted normally to switch to different piles alternate sheets, and man- 'ually operative means for arbitrarily reversing the action of the switching means while the machine 15 operating.
The Invention also comprises other details of construction which will be more speclfically described and illustrated.
Referring to the drawings, illustrating by way of example, suitable mechanism for effecting my invention Figure 1 is a plan view with tapes, side guides, pushers, chain guards and gulde rods removed. Fig. 2
1s a side elevation of half of the machine.

In describing the present invention it will be understood that the sheets from the pile 60, resting on table 61, see Fig. 2, are fed forward by the combing wheels to the drop and feed rollers 62 and 63 in the usual manher and by mechanism similar to that shown in my Patent No. 789,809, May 16, 1905. The relative position of the drop and feed rollers 62 and 63 with respect to the mechanism of the present invention is shown in Fig. 22.
lt will be understood that the pile of sheets resting on table 61 is composed of printed sheets and slip sheets normally alternately arranged. ln'order that the machine work automatically, irrespective of the arrangement of the slip sheets and the printed sheets, it is necessary that one be thicker than the other.
The present machine embodying my invention has been adapted for operating upon slip sheets which are thicker than the printed sheets. It will of course be understood that by slight changes in the several parts, the device would be equally effective for operating upon slip sheets thinner than the printed sheets. As the sheet reaches the drop and feed rollers (32 and 63, see Fig. 22, it passes between the elements of a calipering device, as indicated in Fig. 22, which controls an air vent from a c amber containing a pneumatic diaphragm, such as is shown in Figs, 27, 28 and 29. This diaphragm controls mechanisms for shifting pins in arotating element, which we-will term a time wheel. 'lhese several pins, according to whether or not they are shifted by the diaphragm, either omit to, or actuate a switch which determines the course dr direction of travel of each respective sheet which asses throu h the detector or caliper elements. That is to say as the sheet passes throu h the caliper elements and then through t e drop and feed rollers 62 and 63, and then through the drop and feed rollers 64 and 65; it travels on suitable tapes in the usual way between rollers 66 and 67 to the stop (38, whence, according to the position of the switch mechanism, the sheet takes one of two different directions of travel.
Switch mcciicmiom.'llhis switch mechanism is shown in Figs. 27, 30, 81 and 32, and. consists of the member 69 mounted on. the rocking shaft 7 0. The point 71 of member 69 is adapted to project into thc annular channel 72 of roller 67. This is shown'in Figs. 31 and 32. lit is also adapted to rock to the position in which the point stands away from the roller and out'of the annular channel, as shown in dotted lines in Fig. 27. It will be obvious that when the point 71 lies within the channel 72 of roller (57 the sheet traveling bet-ween rollers 6G and 67 will travel over the top surface 74 of men1- her 69, whereas when the point is raised out of the channel 72 and away from the surface of roller 67, the sheet will be deflected by the are shaped surface 73 of member 99 and thus carried around the roller 67. When the sheet passes over the incline surface 74 of member (39 it is carried by the rods 75, see Figs. 7 and 22 beneath the tapes 76, to a pair of nippcrs 77. These nippers 77, there being two pairs, are carried on a pair of chains 79. These nippers are properly actuated to have an open position to receive the sheets, and are t ion closed upon the'shect to move the sheet forward and then deliver the same to a pile 80, see Fig. 3 as hereinafter to be described When the sheet passes between the roller 67 and the are shaped surface 73 of switch (59, it passes between the rods 81 and 82, see Figs. 7 and 22, to the nippcrs 78, whereby it is carried and delivered to the pile 83, see Fig. 3. When the sheets are delivered alternately t0 nippers 77 and 78, only alternate pairs of nippcrs 77 and 78 will receive the sheets, the others moving idly.
Ualpering dcoice.-'lhc caliperiug device is shown in Figs. 23, 24-, 25 and 2(3. lts relative position with respect to other parts is indicated in Figs. 1, 2 and 22. This calipering device comprises. a sleeve S l. This sleeve 84: is adjustably secured to the hollow rod 85, which is connected with the stationary framework. This sleeve supports the bifurcated uidcs 86 between which is trunnioned at 8 the caliper element 88. lntcgral with caliper element 88 is the upwardly extending arm 89, controlled by the spring 90 and having the surface portion 91 adapt ed to engage. and close the end of nozzle 92. The other caliper element is indicated by 93. -By suitable adjustment of the guide 86 which is secured by the graduated nut 94, threaded on the rod 85, the required space between the caliper elements 88 and 93 is secured. The spring 95 is provided within the hollow rod 85 and presses upon the lower. part of the sleeve 84 and serves by opening the discharge nozz e 92.
to takeup all pla between the adjustable nut 94, the fed 8 and the sleeve 84. The spring 90 normally maintains the part 91 of arm 89 against the end of nozzle 92. It will be noted that the nozzle 92 thereby serves as a stop for the arm 89 and conseuently for the calipering element 88. In t is position by a suitable adjustment of sleeve 84, a sufiicient clearance is left between the culiper elements 88 and 93 for the passage of the thinner of the two sets of sheets, whereas when a thicker sheet, for eriample a slip sheet, is presented to the callpering elements, there is not sufficient clearance, while said elements are in said normal positiomand element 88 is thereupon raised y the thicker sheet. This carries the arm 89 into the position shown in Fi 24:, thirtier 6 spring 90 is connected at its upper end to tie pm 96 which is'slidably mounted for the purpose of adjusting the tension of the spring. The spring 90 is connected at its lower end with the arm 89. This spring normally maintains the part 91 of arm 89 against the end of nozzle 92, and hence maintains the caliper element 88 in its lowest position. At the same time, due to the direction of the pull of the spring, it maintains the trunnions against the upper surfaces of their bearings and thus takes up all possible play of the caliper element.
Tail gripper.-As the sheets pass through the drop and feed rollers64 and 65 they are carried along the tapes 97 beneath the rods 98 toward the drop and feed rollers 66 and 67 and the stop 68. In order however to reduce the speed of travel of the sheets along tapes 97 just prior to their striking the stop 68, I provide the following mechanism. The wheel 99 is provided with a projection 100, see Fig. 22. The wheel 101 is adapted to coiiperate with said projection 100. Wheel 101 is preferably mounted on a resilient support and provided with a yielding surface having suitable frictional qualities, such as rubber. The diameter and speed of revolution of wheel 99 is so related that the projection 100 will engage each sheet against the wheel 101, just previous to the front edge of the sheet reaching the stop 68, so as to reduce or check the speed of the traveling sheet just prior to its engagementwith said stop 68, in order to prevent injury to the sheet or the violent rebound thereof.
Side gui 7es.Upon reaching the stop 68, the sheet is enga ed between the jaws 102 and 103 of the si e guide nipper, shown in Fig. 20, which operates to bring the sheet into proper register against stop 104 in manner similar to that shown in my Patent No.
942,079'dated Dec. 7, 1909. After being brought to proper register, the sheets are then delivered, between rollers 66 and 67,
either to pile 80 or pile 83 as the case may be, as above described.
Pneumatic switch actuation-As already pointed out, when a thin sheet passes through the cali erin device, the elements thereof are una ecte but when a thicker sheet, such as slip sheet, passes through the caliperin device an air nozzleis opened which a ectsthe pneumatic head controlling the switch actuation. The pneumatic head is shown in Fig. 29. This pneumatic head comprises the casing 105 containing a diaphragm 106 which is connected with the piston 107. This diaphragm 106 is subjected to the pressure of an air supply, from any suitable source, such as blower 221, connected through .pipe 108, which tends to keep the piston extended into the position shown in solid lines against the tension of springs 109. This piston carries the guide member 110 which is provided with incline surfaces 111 and 112 adapted to cooperate with .pin 113 carried by the wheel 114.
The position of the guide member 110 depends upon the pressure in the chamber 115 back of diaphragm 106. This is controlled in the following manner: The feed of air to chamber 115 through pipe 108 is reduced to the very small opening 116 by means of a flattened plug 117 inserted in the restricted channel 118 which communicates with pipe 108. Connected with chamber 11:) is also the pipe 119 which terminates in the nozzle 92 as shown in Figs. 23, .24 and 25. When nozzle 92 is closed the pressure of air admitted through aperture 116 is sufficientto actuate diaphragm 106. and piston 107, against the tension of springs 109, to carry the guide 110 into the position shown in solid lines in Fig. 29 and to maintain it in such position; When however, nozzle 92 is opened by the movement of the calipering element and arm 89, as already described,
the air will escape from chamber 115 through pipe 119 faster than it can enter through aperture 11 6,due to the relative capacities of nozzle 92 and aperture 116, with the re suit that ressure is reduced in chamber 115 and .the (iaphragm 106 and piston-rod 107 yield to the tension of springs 109 to carry the guide member 110 into the position the switch arm 120 and hence does not dis-- turb the position of the switch 69 as shown in l igs. 27 and 32.
it will be understood that the time wheel and the particular pin actuated is so timed to the position and movement of the particular sheet passing through the calipers, and thereby allecting or not afi'ecting the pin, that the switch will be in the position indicated in advance of the time the sheet reaches a position to be ail'ected. by the switch.
When a thick sheet, such as, for example a. slip sheet, passes between the calipering elements as already described, the nozzle 92 is opened and airpassing from chamber permits the piston 107 and the guide member 1 10 to respond to the actuation of springs 109, to move into position shown in dotted lines in Fig. 25). in this position the pins 113 are not affected by the guide 110 and will encounter the switch member to actuate the same against the tension of the spring 122, to move the switch member (39 into the position shown in dotted lines in Fig. 27, that is, the point 71 is raised out of channel 71 and away from the surface roller 67. This insures the passage of the slip sheet around the are shaped surface 73.
lit will be understood that each sheet actuates the caliper to control the actuation of a particular pin 113, which controls the actuation of the switch just in advance of the time that that particular sheet reaches the switch. The double incline of guide 110, also of guide 121, is simply to prevent accident in use the machine is turned backward.
1i and operating mcc/mnJsm.Tn case there is not sullicient ditl'erence in the thickness of the sheets to cause this automatic detection or calipering which controls the pneumatic shifting of the pins, a. hand controlled device may be utilized for securing the switching of alternate sheets to the different piles 80 and 83.
Ordinarily or normally, slip sheets and printed sheets are piled in alternate relation. it happens however that two slip sheets may sometime be together or there may be a failure to feed one or the other of said sheets so that this order of arrangement may be reversed from time nto time. To meet this condition the following mechanism is prorided: The hub 123 is feathered on the shaft 124 of the time wheel 114 so that said hub will rotate with said time wheel. On this hub are provided the two arms 125 projecting into the same plane, and the arms 126 also projecting into the same plane but in a different plane from that of 125. Arms 125 are provided with pins 127, While arms 126 are provided with pins 128. As shown in Fig. 30 this hub and its several arms are all in the neutral position, that is, in a position that they will not encounter the lever aoee eoe 129 which is also connected with the switch 69 as clearly shown in Fig. 31. The hand lever 130 is pivoted at 131 to the stationary framework and is connected with the hub 123 by a pin projecting in the annular channel 132. By pulling the handle 130 to the left the hub is moved carrying the pins 127 into the operative osition so that the arm 129 will be actuated for alternate sheets. [is long as this corresponds to the order of the sheets being delivered, they will be properly distributed to the two piles. When however the order changes, the lever can then be moved to the right bringing pins 128111 the operative relationship with lever 129 and the switch is again shifted to change the order of delivery. It will be understood that when the hand operating mechanism is used, the cam. or guide 121 is removed, so that the pins 113 may remain in the in-- operative position.
Nippcr supporting and actuating meamn As all the nippers are alike and are similarly actuated, it will be sufficient to describe one set, such as shown in Figs. 15 and 16, which are carried by the chain 79. The chain 79 is carried by the sprockets 133 and 134. Both of these sprockets are mounted on studs on a common frame, which frame is adjustably mounted on the machine. For example, sprocket 133 is mounted on the stationary stud 135. This stud is mounted on the adjustable frame 136. The sprocket 133 is provided with a hub upon which is mounted the gear 137. Gear 137 is driven by gear 138 feathered on shaft 139. The said gear 138 is kept, in all positions of adjustment, in proper relation with gear 137 by means of the yoke 140 connected with the frame 136 and the channel 141 connected with gear 138. It is obvious of course that shaft 139 is connected with suitable source of power and operated relatively with the other parts of the machine. Sprocket 134 is mounted on stud 142 which is mounted in the slot 143 in the same framework 136 and provided with a tightening bolt 14-4 for the purpose of taking up wear on the chain or maintaining proper tension thereof. The entire framework 136, carrying both sprocket wheels, is slidably mounted on the rail 145 having a dove tailed engagement therewith. Said frame is further supported on the rail 146, and the adjustable actuation of said frame is secured by means of the adjusting screw 147. All of the nipper sprocket carrying chains are similarly mounted, and adjustable to suit the size of the sheets to be acted upon.
Nipper 00nstmcti0'a.As shown in Figs. 10, 13 and 14, the nipper comprises a fixed jaw 148 and a movable jaw 149. The fixed jaw 148 is integral with the channel portion. 150, forming a link in the chain as clearly shown in Figs. 10 and 14. The movable jaw member is secured to the pin 151. To pin 151 is secured one end of spring 152, while the other end is secured to the collar 153, which may be turned for adjusting the tension of the said torsional spring 152. This spring serves normally to maintainthe movable jaw 149 in the closed position with respect to the fixed jaw 148. Connected with the movable jaw 149 is the arm 154, carrying the antifriction roller 155. This antifrietion roller is adapted to engage, during the travel of the chain around the sproclret wheels, with the stationary cam surface 155, to cause the opening of said nipper to receive the sheet at the beginning of its travel. Upon leaving the surface of said cam the nipper closes, due tothe actuation of the torsional spring, as above described, to hold the sheet and carry the same to the delivery position, whereupon the nippers engage the cam surface 156, to cause the opening of the same to release the sheet just prior to its encountering either step 157 or stop 158, as: the case may be, see Figs. 2, 3 and 5.
Guides and j0gg@rs.--After the sheets have reached stops 157 or 158, as the case may be, they float down upon their respective piles 80 and 83 between guides 157 and 159 and between guides 158 and 160. Suitable guides such as.161 and 162 are also provided on the sides of the sheet to coiiperate in causing the sheet to float down straight onto the pile. Joggers, such as 163 and 164. are provided suitably connected and actuated for jogging the sheets on three sides of the pile to keep the pile true; examples of such actuating means are shown in Fig. 5 and indicated by the cam 165 and cam 166 and the levers and connecting rods shown in association therewith.
An example of a jogger and guide located on the side of the machine from which the sheets are withdrawn, is illustrated in Figs. 20 and 21, also in Fig. 2. 167 indicates the guide and 168 the jogger. These elements are pivotally mounted so that they may be made to withdraw their obstruction from the pile when it is desired to move the pile of sheets from the machine. The guide 167 is pivoted at 169 and is provided with suitable latching means to hold it in either of two positions. The jogger member 168 is pivoted at 170 and is adapted to turn on said pivot to assume the horizontal position above the pile of sheets. In Figs. 34 and 35 is shown another jogger 171 which is slightly different in form and which is used in connection with pile 80. The actuation is similar to the actuation of the jogger shown in Fig. 26.
Tabla actuating mechanisms-The piles 80 and 83 are delivered to the tables 172 and 173 respectively. These tables are mounted on frames which are supported by the screws 174 and 175, see Figs. 1,2 and ,3. These screws are turned in one direction .to elevate the table and in another direction to lower the table.
Lowering a0tuation.-It is desirable that there may be a lowering actuation to correspond approximately to the feed of the sheets thereto. It is also desirable that there may be anactuation independent of said feed where it is desired to lower the table arbitrarily to-the truck or the like. For these different actuations I provide the following means: Referring to Figs. 36, 37 40 and 41, the driving shaft 176 is provided with a friction wheel 177, provided with a suitable peripheral frictional surface. This wheel 177 coiiperates with a frictiondisk 178 which is mounted on the shaft 179 and is provided with the spring 180 for securing the proper pressure contact between the two frictional elements. The adjustment of spring 180 is secured by the nut 1.81 on the'threaded sleeve 182 which surrounds said shaft 17 9. Shaft 179 is provided with gear wheel 183 and also with the worm 184. Gear 183 coiiperates with the gear 185 mounted on shaft 186 which carries at its other end the beveled gear 187. Worm 184 coiiperates with the gear 188 loosely mounted on shaft 189, while gear 187 coiiperates with gear 190 also loosely mounted on shaft 189. It will be noted that the gear 190 and gear 188 are driven in the same direction and that the said gears are so proportioned that gear 190 is driven at a. much higher speed than gear 188.
0Zutch.-Mounted and feathered on shaft 189 between the gear 188 and gear 190 is the clutch element 191 having a double clutch face. One face is adapted to coiiperate with the clutch face on 188 and the other is adapted to coiiperate with the clutch face on element 190. This clutch element 190 is also connected by a suitable yoke 192 with the actuating lever 193. This hand lever 193 is provided with the spring controlled bolt 194 which is also manually operated by the maintaining clutch relations .with 188, the other clutch relations with 190, while the middle hole maintains the clutch in the neutral position. It will thus be seen that with the clutch in relationship with 188 the table is fed downwardly in approximate relation with the feed of sheets thereto while in clutch relation with 190/the table may be lowered arbitrarily at much reater speed. It will be understood that sha t 189 is properly geared by bevels 197 and 198 to shaft 199, see Figs. 36 and 39 and shaft 199 is provided w1th a gear 200 cotiperatin with a gear 201 on the screw 174. l't will e understood that the pair of screws for each table are driven together.
I Adjustment of cede-In order to secure the required spee to correspond with the hand clamp 195 and the bolt is adapted to engage in either of three holes 196, one hole-
