CHARLES M. MEAD, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF T0 MARK M. VIORSTER, 0F LOS ANGELES, CALIFORNIA.
DOUBLE-DECK WEB BED-AND-PLATEN PRINTING-PRESS.
Application filed August 9, 1911.
To all whom it may concern:
Be it known that 1, CHARLES M. MEAD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Double-Deck Web Bed-and- Platen Printing-Press, of which the following is a specification.
This invention relates more particularly to a job printing apparatus by means of which duplicate order books and the like can be simultaneously printed, perforated, numbered and assembled.
It also includes an attachment applicable for use with one or more job printing presses for the purpose of feeding a web to the press and of taking the web from the press, and delivering the printed sheets ready for issue, either as single sheets, consecutively numbered or otherwise; as letter heads, dodgers and the like; or as duplicate sheets, plain or consecutively numbered as the case requires; or as bill-heads and the like perforated and numbered in duplicate.
An object of this invention is to provide a novel unitary machine which will perforate in duplicate, number in duplicate, cut in duplicate and gather in duplicate sheets properly arranged as original and duplicate sheets ready for delivery to the stitcher and binder for making books or pads of billheads, sales-books and the like.
Qther objects of the invention are simplicity, compactness and invariable appropriate performance of the necessary operations at the proper times.
Duplicate order books are usually made of a determined number of so-called original sheets interleaved with so-called duplicate sheets, the original sheets being consecutively numbered from unity beginning at the top original sheet and ending at the bottom original sheet, and the duplicate sheets being correspondingly numbered, one for and following each original sheet; the number of original sheets in each book varying according to convenience; and I shall illustrate the invention herein as adjusted for numbering books comprising fifty original and fifty duplicate sheets.
Another object is to provide for adjusting the mimbering de ices to the ditterent sizes and forms of original and duplicate sheets, also to adjust the machine so as to number the leaves of some of the books and Specification of Letters Patent.
Serial No. 643,215.
to omit to number the leaves of others of the books being printed at one run, so that a single run of the press may produce one or more sets of numbered books, and one or more sets of unnumbered books; thus at one run, to supply various wants of different customers.
A further object is to provide means for issuing clean-cut sheets. This latter object is effected by providing means gripping the original and duplicate sheets while the same are being severed from the body sheets.
Other objects and advantages of this invention may appear from the subjoined detail description.
F or convenience of description the terms original web and duplicate web will be used to designate the webs respectively for forming the original and duplicate sheets of the manifold.
Broadly considered the invention includes the combination with a platen printing press, of means for feeding a web to the press, and rotary means timed with the press to intermittently draw the web from the press.
It also includes the combination with the parts just enumerated, of means for feeding a second web to the web drawing means and mechanism timed with the web drawing means for cutting oil the webs into sheets.
It also includes the combination with two platen printing presses of means for feeding webs to said platen printing presses, means timed with said presses to intermittently draw said webs from said presses, numbering mechanism timed with relation to the intermittent web drawing means and mechanism timed with said intermittent web drawing means to cut oil sheets from the web.
Other objects, advantages and special features of invention may appear from the subjoined detail description.
The invention includes the combination with one or two platen presses, as may be required, of a double deckrotary web attachment; and it also includes said attachment and parts thereof. Said double deck rotary web attachment comprises a combination of mechanisms which may be enumerated as follows :Mechanism X for drawing the webs; mechanism A, for adjusting the upper web relative to the cut-off;

Fig. 25 is a diagram illustrating the travel of the original and duplicate webs when the attachment is combined with only one press for printing only the original sheets the duplicate sheets being left blank.
The invention may be applied as a unitary machine having a single unitary frame of any desirable form, which carries two platen presses and the apparatus which I call the attachment, all arranged in fixed relation to each other on the one frame. F or convenience in supplying the invention at minimum cost to printing establishments already supplied with one or more platen printing presses the apparatus herein termed the attachment may be can structed independently of a specially manufactured frame for the printing presses; and where it is desired to mount both platen presses and the attachment on a common floor Y, said attachment will be placed between the printing presses as indicated in Fig. 2i, and said lioor will serve as a common frame for both presses and the attachment.
In the drawings 1 and 2 represent webs fed from rolls 3, 1-, which may be situated on opposite sides or both on one side only of the attachment. These webs when run through the attachment are finally brought together with those sides up; ermost which are to receive the numbers, the duplicate being underneath the original.
5, 6 designate the two platen presses between which may be located the attachment through which, in the complete apparatus, the two webs are run on their way from the platen presses to the tray on which the completed sheets are finally laid.
here both original and duplicate sheets are to be printed the web 1 is led from the roll 3 to tie press 5 and from such press over suitable guide-rol ers to the upper part of the attachment; and the web 2 is led from the roll 4 through the platen press 6 over the guide-roller 7 into the attachment underneath the original web as diagramed in Fig. 2-l. lVhere the attachment is between the presses, and only the original is to be printed and the duplicate is to be unprinted, the web 2 is used as the original; being led through the press over the guideroller 7 on to the upper part of the attachment, while the web 1 is led from the roll 3 directly to the lower part of the attachment as shown in Fig. 25, without being passed through a press.
In Fig. 2% the web 1 is led up from the press over the guide-rollers 3, S and 9 which are above the mechanisms of the attachment, and thence down to the top-web adjusting roller 10, thence over the perforating roller 11, thence underneath the rider roller 12, thence around the pair of pulling rollers 13, 14- and thence out between the delivery pulling rollers 1 1 and 15. The duplicate web is led from the press 6 over the lower guide-roller 7; and thence under the lower web adjusting roller 10 thence over the duplicate perforating roller 11"; and thence under the lower pulling roller 16 and around said roller and between it and the delivery pulling roller 15 and thence out between the delivery pulling rollers 14 and 15 and beneath the web 1.
here it is desired to print only the original, the web 2 is used for the original and is passed through the press 6 over the guideroller 7 under the lower web adjusting roller 10"; thence over the perforating roller 11 and thence to the pulling roller of the web drawing mechanism X, as above described, while the web 1 is led directly from the roll around the guide rollers 18, 19, 20; thence over the perforating roller 11, and thence under the lower pulling rollers 16 and 15 and out from between the rollers 15 and 14 toward the cutting mechanism I.
The numbering devices 21 and 22 for the two webs are arranged between the perforating rollers 11 11" and the pulling rollers of the web drawing mechanism X.
It is thus seen that a feature of this attachment is the arrangement of web drawing mechanism at one end and web adjusting mechanism at the other end of the attachment and mechanism for operating on the web, as the perforators and numbering devices between the adjustable web adjusting rollers and the web drawing rollers; and said web-drawing mechanism and numbering devices work intermittently and alternately to one another.
The presses 5 and 6 may be reversely fed as in Fig. 21 so that the printing effected by one is on the under side and that effected by the other is on the upper side of the webs, respectively at the presses and numbering is done on the upper side of both webs at the numbering devices.
In the arrangement shown in solid lines in Fig. 24L the webs are reversely arranged and the pressesare set with the type facing away from the attachment; and when both its press 6 at the top and leaves such press from the bottom, and consequently the printing is at all times on the upper side of the web 2.
Ordinarily where an attachment has been installed and only one press is to be used, the arrangement will be such as is shown in Fig. 25, the web 2 being taken from the roll directly to and over the guide-roller 7 and under the lower web adjusting roller 10 and the web 1 will be carried as directly as possible to the perforating roller 11. In this way the long pull on the web that is apparent in Fig. 24 between the press 5 and the adjustable roller is avoided, but by providing the guide rollers 3 8, 9 the use of two old presses with a new attachment is made easy and by providing the guide rollers 18, 19 and 20 the pull on the unprinted web is shortened. However, when the two platen presses and the attachment are in the relative positions shown in Fig. l the web 1 remains as the original web and may be printed by the press 5 while the press 6 is standing still; being thrown out of gear by a clutch, not shown.
Where the original and duplicate webs are to be printed as indicated in Figs. 1 and 24:, it is necessary that the printed portions coming from the two printing presses must exactly register with each other and in order to secure such registration it is necessary that the length of the web between the delivery web drawing rollers li and 15 and each of the presses shall be in each instance some exact multiple of the size of the printing forms of the press and it is also necessary that the cut-off shall operate in due relation to the delivery rollers lt and 15 as they deliver the printed sheet.
The frame 23 of the attachment when made as a separate part of the machine is of any desired construction, preferably of angle-iron or channel-iron, these difierent materials being used in accordance with the best methods of the structural art within the judgment of the builder.
Mechrmsm A for adjusting the upper web.-Referring now to Figs. 3 and 4, the upper web adjusting or take-up roller 10 is carried by an adjustable head 24; fixed by bolts 25 to connections that are preferably sprocket chains 26 which pass around the upper and lower pulleys that are preferably sprocket wheels'27, 28 arranged in pairs. The upper sprocket wheels 27 are fixed by set screws 29 to a shaft 30 which'is j ournaled in boxes 31 on the frame 23 and secured against shifting by means of collars 32 and. provided with a handle 33. The lower pulleys 28 are mounted on a common axis 3 journaled in the arms 35 and secured against shifting by collars 36. Said arms 35 are pivoted by pivot bolts 37 to the frames 23 and are adjustably held by tension bolts 38 by means of which the arms 35 may be drawn down in order to hold the endless connections 26 taut. The upper web adjusting roller 10 is adjustably secured to the head 24 by bolts 39 that are held between the head 24 and the head bar 40 and that pass through slots tl in journal hangers 42 in which the journal pins 43 of the roller 10 are carried. The bolts 39 are held between the head 24 and the head bar 40. Said head bar is held to the head 24: by the bolts 44: paming through the spacers 45 located between the head 24; and the head bar 410. Said head and head bar are mounted between the vertical guides 46, 47 arranged in pairs on opposite sides of the machine and which form the vertical ways 48 for the ends of the head and head bar. Space blocks 4-9 are held by the bolts as to contact with the guides 46, 47 to prevent endwise movement of the head and consequently of the roller. The handle 33 affords means to move the connection to move the head and theadjusting roller up and down.
The mechanism B for adjusting the lower web relative to the cut-off and other mechanisms that operate on the printed web below the levels of the supporting rollers 9 and 11 thus to increase the distance the web travels between the press and the cut-off and other mechanisms that operate on the printed web is practically the same as that just described and in the drawings the parts of the mechanism B which correspond to parts of the mechanism A are indicated by corresponding characters with the addition of indices.
Mechanism 0 for pepfomting the upper weY).The perforating wheel 50 is a finelytoothed sharp-edged wheel j ournaled by the stud 51 on the arm 52 fixed to a shaft 53 that is journaled in clamping boxes 54 on the frame 23 and provided with a handle 55. The clamping boxes 54 are blocks provided near one end with a bore 56 to receive the shaft 53 and being split at 57 to form arms 58, 59 which are transversely bored to receive a bolt 60 which passesthrough a flange 00 of an angle-iron forming part of theframe 23, said bolt 60 being provided with a thumbnut 61, so that the arms 58, 59 can readily be drawn together so as to hold the shaft 53 with any desired degree of friction, by this means to adjust the perforating wheel 50 into and out of cooperative relation with the perforating roller 11 as shown in Figs. 3 and 1, respectively. The perforating roller 11 is provided at intervals of about t of an inch, more or less, with grooves 62 into which the sharp tooth edges 63 of the perforator wheel 50 may run. The gudgeons 6-l of the perforating roller 11 are carried in notches 65 of brackets 66 fixed to the frame and when the perforators 50 are thrown out of commission as seen in Fig. 1 the perforating rollers may be lifted out and replaced as described.
The perforating wheel can be adjusted to any suitable positions upon the shaft 53 and may be securely fixed thereto by set screws. The perforating wheel may be raised and lowered out of and into commission as desired by means of the handle 55. Any desired number of perforating wheels may be applied on the shaft 53.
The mechanism D for perforating the lower web corresponds to that just described and parts corresponding to those of mechanism C are indicated by corresponding characters with the addition of an index.
Separate numbering V mechanism is employed for intermittently numbering the webs respectively between the presses and the web drawing mechanism. The numbering mechanisms are operatively connected with and are timed with the platen presses.
1U eeham'sm E for numbering the upper web.The mechanism for numbering the web (see Figs. 6, 7 8) comprises a bed 67 under the web, an automatic numbering machine 68 and intermittent mechanism connected with the operating parts of the apparatus to intermittently operate the numbering machine in synchronism with the platen of the press. Any desired number of the machines 68 may be employed, there being as many automatic numbering machines as there are bill heads or other printed articles contained in one impression of the form.
The automatic numbering mechanism is provided with a cross-head formed of bars 69, 70, spaced apart by washers 70" and fastened to each other by bolts 71 and being in parallelism with the web-carrying rollers, and forming tracks for the numbering machine carriages comprising opposite sides of said bars 69, 70, and adjustably clamped upon said bars by bolts 72 having thumb nuts 73 provided for that purpose.
The stems b of the numbering machines are fixed by pins 0 to axles (Z which are ournaled in the blocks a and against which axles the type and ink-pad retracting springs e impinge to normally hold the guide feet 7 depressed toward the web and allowing the stems b to move down relative to the feet when said feet impinge upon the web; and thus allowing the type to be forced down onto the inking ribbon above the web.
By means of the axles the numbering ma chines are gravity-adjusted to properly act on the inking ribbon above the web.
By constructing the cross-heads and carriages as shown, one or more numbering machines may be mounted on each cross-head and can be shifted therealong transversely of the web so as to provide for numbering the web at whatever point required. Each numbering machine is independently movable. Said cross-heads are provided with perforated end plates 74, 75, through which vertical actuating rods 76 play, said rods being provided with adjusting collars 77 held by set-screws 78 to support the lower end plates 75. Depressing springs 79 are fixed on the rods 76 by adjusting collars 80 which compress the springs 79, thus yieldingly holding the cross-head down firmly upon the supporting collar 77. Longitudinal clamps formed of bars 81, S9,.held toward each other at their ends by bolts 9 are provided to mount the slidable rod guides 83 and also to support transverse shafts.
The rod guides 83 are slidable on and adjustably fixed to the guide bars 81. 82, by means of clamp bolts it that pass between said guide bars and are tightened therein by nuts 2'. Boxes 7' having studs 7r that also pass between and are clamped by guide bars 81, 82, are provided to support ribbon roller shafts hereinafter described.
Several sets of upper and lower numbering mechanisms may be provided for the apparatus. In Fig.6two such sets are shown. The upper and lower cross-heads of each set are connected together bv the vertical actuating rods 76 that work through the guides 83. and that are provided with extens on joints 84 pivoted at 85 to the rods 76 and pivoted at 86 to U-shaped sliding clamps 87 that are fixed by bolts 88 that pass through the limbs of the clamp and are secured by the wing nuts 89. Said clamps 87 are adiustablv clamped on the cam levers 90 provided with the riders formed of rollers 91 that rest upon the peripheries of the cam wheels 92. The rollers 91 are mounted in pairs upon shafts 93 93 and the cam wheels 92 are mounted in pairs upon the secondary shaft 94 and the main shaft 94.
The means for numbering the lower web correspond to those just descr bed and are marked in the drawings with like characters distinguished by indices.
In Figs. 6 and 7 like parts are designated by like characters, ind ces being applied to such characters to distinguish the parts variously located. The secondary shaft 94 shown in Figs. 6 and 7 is driven by the main shaft 9 through sprocket gears 95 and chain 96. The parts more directly relating to the main shaft 94 are distinguished by indices. The shafts 94 and 94 are journaled in boxes 97 fixed to the frame 23 and the sprocket wheel 95 and the cam wheels 92 are fixed on the main shaft 94: which is driven by the large sprocket wheel 98 driven by the sprocket chain 99 driven by the speedincreasing gear 100. The peripheries of the cams 92 and 92 are mainly circular, being provided with recesses 101, 101 adjoining the circular portions 102, 102 that are .curved so as to allow the riders 91, 91 to the weights of the levers 90 and 90 and the numbering mechanisms carried thereby respectively, so that at each revolution of the cams 92 92 the rods 81 are vertically reciprocated. On the main shaft 91' is also fixed the knife-operating cam 101 which carries the wiper wheel 105 the stub axle 106 of which is fixed to the knife-operating cam 101. As the levers 90 and 90 move up and down they vertically operate the cross-heads and the numbering machines carried thereby.
Mechanism G and H for shifting the inking ribbon-The inking ribbon shifting lever 107 is fulcrumed to the frame 23 by the fulcrum pin 108 and is arranged above the wiper wheel 105 and is pivotally connected by the pin 109 with the vertical connecting rod 110 which is guided by the guide 112 that is fixed to the frame 23. Said connecting rod 110 is pivotally connected by means of pins 113, 113 with the slotted pawl-levers 11 1, 111 which are fulcrumed on the axes 115, 115 of the ribbon rollers 116, 116', there being ratchet wheels 117, 117 fixed to the axes 115, 115 and operated by the pawls 118, 118 that are pivoted to the pawl levers. It is thus seen that at each revolution of the knife operating cam 101 the ribbon roller will be rotated a distance, thus shifting the inking ribbon 119, 119. Sets of ribbon-shifting rollers that are practically alike are reversely arranged on opposite sides ofthe connecting rod 110, so that whenthe pawls 118 on one side of the connecting rod are in engagement, the ribbon will be shifted in one direction'and when the pawls 118 on the other side of the connecting rod are in engagement with the ratchet wheels the ribbon will be shifted in the other direction, care being taken that only the pawls on one side will be thrown in at the same time. The ribbon passes from one ribbon roller 116 to the other ribbon roller 116 under depression rollers 120 which extend across the machine and are located just above the paths of the webs 1 and 2.
Mechanism 1 for cutting the printed and numbered duplicate sheets from, the web..At each revolution the knife-operating cam 101 (see Figs. 1 and 19) depresses the roller 121 which is mounted on the cutter lever 122 that is fixed by bolts 123 to a in a stationary box 128 that is fixed on one side of the frame 23. The cutter shaft 127 carriers the cutter arm 129 fixed thereto, and to the end of which is pivoted by a pin 130 the knife-operating connecting rod 131 that is pivoted at its upper end by pivot 132 (see Fig. 13) to the cutter knife 133 which is pivoted by the pin 131 to the lower stationary blade 135 of the cutter. A spring 136 (see Fig. 1) is connected at its lower end to the cutter lever 122 between the box 121 and the roller 121 at its upper end to a bracket 137 that is fixed to the frame 23. The purpose of this spring is to hold the cam roller 121 against the cam 101. The cutter shaft 127 extends across the frame 23 and through a box 138 and is provided with an arm 139 to which the cutter arm retracting spring 110 is connected to assist the spring 136 to lift the cutter knife 133. By means of the springs 136 and 110 the cutter lever 122 the cutter arm 129 connecting rod 131 and the free end of the knife 133 are normally raised to admit the web between the knife'and the lower cutter blade 135.
It is necessary that the paper be held firmly on both sides of the knife during the operation of cutting and also that the web shall be stripped from the knife as the knife rises. The delivery rollers 11, 15 hold the webs on one side of the cutter, and the movable gripper aw 111, in connection with the stationary gripping aw 111, intermittently hold the webs on the delivery side of th cutter.
The stripper 112 loosely rides on the top of the knife, and is provided at its ends with sleeves 113 that slide up and down on the gripper operating rods 111 to which the gripper jaw 111 is fixed, and which rods slide up and down in guides 115. Said rods are mounted at their lower ends on a cross bar 116 (see Figs-11', 12,) which is fixed by nuts and bolts 117 to a central gripper lever 118 that is journaled by the box 119 on a shaft 150 that is journaled in boxes 151 on the frame 23.. The lever 118 is provided at its sides with rollers 152, 152 which are operated in succession by the intermitting cams 153, 151 that are adjust-ably fixed by set screws 155 to the main shaft 91. The gripper lever 118 is yieldingly held down by the spring 156 and is lifted in opposition to said spring by the intermittent cams 153, 151 which are arranged in such operative relation to the other parts of the machine, that, just preceding the descent of the knife 133 they will allow the-spring 156 to bring the gripping jaw 111 to gripping position.- The intermittent cutter operating cams 153, 151 have carrying arcs 157, 158 of more than 180 concentric with the main shaft 91'. The cam wheels are spirally arranged relative to each other on the shaft to leave a recess 159 between their carrying .arcsl57,
158 so that during the greater portion of the revolution of the main shaft 9 1- the cams will support the lever 118 to uphold the gripping jaw 141, but during a less portion of such revolution will allow the lever 14 8 to descend. The recesses 159 of the cams are on one side of the shaft to allow the rollers 152, 152 to be simultaneously fully depressed for an instant so that the gripping jaw 111 may be momentarily forced by spring 156 to grip the webs.
The rollers 152 and 121 are arranged on diametrically opposite sides of the main shaft 91 and the tip of the cam 101 is arranged diametrically opposite the combined recess 159. so that the cutting stroke of the knife is effected at the instant the gripping stroke of the gripper is effected. In this way the web is firmly held by the gripper at the instant the sheet is cut off and is then released. The cam 161- forms on one side of the shaft an arc concentric with the shaft and on the other side of the shaft, with a cusp of much greater radius so that both the knife and the gripper bar are normally raised.
By means of the set screws 155 the cutteroperating cams may be adjusted to reduce or increase the "idth of the recess, thus to increase or decrease the length of the gripping and cutting stroke.
In order to prevent the knife from lifting the severed ends of the web as the knife returns upward the stripper 112 is vertically movable relative to the knife, there being for this purpose slotted fingers 160 adjustably fixed to the stripper by bolts and nuts 161 and underneath the web the receiving bed 162 is arranged immediately below the stripper so that when the knife descends the stripper will rest on the webs and hold them tightly on the receiving bed while the knife is making and withdrawing from its cutting stroke. That is to say, the stripper will come into contact with the web immediately before the knife begins cutting the web and will rest on the web throughout the remainder of the descending stroke and a part of the return stroke of the knife; being held in place by the sleeves 1 13 on the rods 111.
Referring now to Fig. 13, broken lines indicate positions of the knife and stripper on the cutting stroke. These positions are clearly seen in Fig. 16. hen the knife ascends the stripper lags behind until theknife is fully withdrawn from the stationary cut-' ter blade 13-5; whereupon the knife again lifts the stripper. In order that the cutting knife may be comparatively light and will make. a close cutting engagement with the stationary cutting blade means are provided for holding the knife tilted transversely away from the stationary blade and sprung longitudinally toward the stationary blade; and the stationary blade is aslant transversely toward the cutting knife. This will.
be understood by reference to Figs. 11, 15, 16, 17, 17 and 17". The knife is loosely fulcrumed on the pin 13-1 and ful ruined in hole 163, the fulcrum pin 131 being of less diameter than the hole 163 through which the pin extends, said pin being screwed into the stationary blade 135 and into the frame An adjustable shim 161 provided with a. slot 165 is fastened to the contact side of the knife by set screw 166. Said shim is bifurcated at its lower edge and is slidable up and down relative to the fulcrum pin 131 between the furcations of the shim. The shim is wedge shape diminishing downwardly, and by shifting it down or up relative to the knife it will tilt the knife at a greater or less angle relative to the stationary blade. At the free end of the knife a swinging arm 1.67 is hung from a stud 168 on which it is secured by collar 169 and the arm is in sliding contact with a finger 170 that projects from the free end of the knife. The swinging arm is resiliently held by a sprin 171 against the finger 170, thereby springing the knife toward the stationary cutter blade 135. The knife spring 171 is held in place by a guide bolt 172 passed through and loosely held at one end by the lower end of the winging arm 167, and held at the other end by the bracket 173 riveted to the frame The lower stationary blade 135 fixed to the frame 28 by bolts 1.7 1 and is held atilt by the shim 175 that is interposed between the blade and the frame. By this tilted arrangement of the blades, the cutting edges are always in cutting relation to each other so that when the knife is moved down it will invariably cut the web smoothly and the blades have a self-sharpening tendency when operated. The stationary gripper jaw 1 11 is tightly fixed on the bolts 176 that are fixed to the frame 23; and is provided on its upper edge with a rubber gripping strip 177 to coiiperate with a like strip 178 on the upper gripping jaw 141 so to cushion the gripping stroke and to insure a tight grip on the webs between said strips.
Mechanism Z1" for resiliently holding the web.-The upper delivery pulling roller 11 is stationarily mounted being journaled in'the bars 179 that are fixed to the frame 23 by bolts 180, and the lower side of the roller is just above the level of the receiving bed 162 so that practically the web coming from the under side of the roller will pass horizontally to the bed. (See Figs. 19, 11, 12 and 15.)
The upper pulling roller 13 is mounted on a lever 181 that is fulcrumed by bolt 182 to the frame 93 and is connected with tension spring 183 to force the upper pulling roller down upon the upper delivery roller, thus gripping the web between the two.
main shaft 9 1.
The lower delivery pulling roller 15 is mounted on a lever 18 1 fulcrumed to the frame at 185 and pressed upward by the spring 186 carried by the rod 187 and hanger 188 which is fixed to the frame 23 and the lower pulling roller 16 is mounted on a lever 189 fulcrumed at 190 on the frame 23 and pressed upward by the spring 191 mounted on a rod 192 which is fixed to the frame 23. By this means the web is gripped and fed in true position to the receiving bed 162.
It is important in the operation of this machine including two printing presses by which both originals and duplicates are simultaneously printed that the webs shall be pulled or fed with exactness, so that they will perfectly register. Otherwise the webs may creep with relation to one another and a slight creeping would mar or spoil the completed job. This fact has proved in many experiments to offer a very great difii culty and to overcome this the pulling rollers are provided with a facing 193 of sand paper or its equivalent.
A satisfactory facing is made of the sandpaper known to the trade as No. 2 garnet, said paper being coarse, rough surfaced, very light and not liable to wear out or become smooth.
In case the facing becomes smooth it may be renewed by replacing with new, the paper being cut to the exact circumference of the roller and its edges being fastened to the roller by small tacks as indicated at 1941 in Fig. 12.
Mechanism L for regulating the length of the web delivered to the cut-0fi.lt is necessaryin a machine of this character that the delivery sheets shall be cut off in certain lengths and that the line in which they are cut off shall exactly register with the division between the printed forms on the webs. For this purpose the pulling roller driving arm 195 is fixed to and revolves with the To this arm 195 is adjustably fixed the crank-pin 196 adapted to lit in any one of the series of holes 197 that are at different radial distances from the main shaft 91. To this crank-pin is connected a pitman 198 which is connected by a wristpin 199 to an adjustable clamp composed of two clamp- plates 200, 201, which are placed face to face and are provided with recesses 202 in which a pulling extension arm 203 may slide; and upon said arm the clampplates may be tightly clamped by means of the clamping bolts 204:, 205, the former of which pass through a spacer 206 that is in contact with the arm 203. The clamp bolts 205 are arranged on the opposite side of the recesses 202 and arm 203 from the spacer 206 for the purpose of springing the clamping plates 200, 201, totightly clamp the pulling arm 203. By loosening the bolts 205 the clamp plates and spacer may slideon the pulling arm 203 radially toward and from the axis 207 of the pulling spur wheel,208 which is rotated by engagement of the detent 209 with the teeth 208 of the spur wheel; said detent being carried pivotally by the pin 210 on the pulling lever 211 that is journaled by the boxes 211 on the axis 207 of the pulling wheel 208. The'spring 212 holds the detent in engagement with the spur wheel 208.
A pair of back stop pawls 213 are mounted on elongated stems 214 that are pivotally mounted on the frame 23 by a stud shaft 215. The tips of said pawls have beveled edges 216 engaging in beveled peripheral grooves 217 in the rim of the spur wheel on opposite sides of the teeth 208 thereof. wires or chains 219 to the stems 211 to hold the back stop pawls in frictional engagement with the grooves on the rim of the wheel 208 behind the detent 209. The purlVeights 218 are suspended by pose of the pawls 213 is to prevent retraction of the pulling wheel 208, the teeth 208 of which mesh with pulling roller main gear 220 fixed to the shaft 11 of the delivery pulling roller 14-. The teeth 208 are fine and the diameter of the wheel is large so as to minimize variation in the cut off. The pullin rollers are provided with gears 223, 22 225 and 226, respectively which are in a train that gives the proper directions to the several pulling rollers 13, 14 15 and 16. 0
In practical operation the crank arm 195 revolves as the shaft 9-1 rotates and this reciprocates the pitman 198 and swings the pawl 209 to rotate the wheel 208. The length of stroke of the pawl can be roughly adjusted by changing the pin 196 to the appropriate one of the holes 197. The fine adjustment of the stroke is then made by shifting the clamp forming the plates 200, 201 along the pawl arm extension 203 to increase or decrease the radius of the wristpin stroke. In this way the length of the web which is drawn forward at each revo lution of the main shaft may be minutely cletermined and accurately gaged, so that each sheet will be of the appropriate length.
Mechanism M for delivering the cut-o7? sheets in sta07c.The fly-operating lever 227 is fulcrumed at one end to the frame 23 at 228 and is provided intermediate its ends with a cam roller 229. A connecting rod 230 is pivoted to the other end of the fly-operating lever 227 and is connected with a crankpin 231 adjustably mounted on the mutilated gear wheel 232 the teeth of which mesh with pinion 233 fixed to the shaft 234 of the fly 235. A retracting spring 236 fastened to the frame at one end and to the crank arm 237 contact with the cam roller 229 and move the lever 227 down so as to operate the fly 235 on the back stroke of the arm 195, thus operating the fly to take the cut-off sheet and deliver it in the tray 240 while the web is resting. The are 239 is about a quadrant so that the operation of the fly occurs only during about one-quarter of the revolution of the main shaft. The fiy-operating cam 238 is adjustably fixed to the shaft 94 by a set screw 241 and can be turned relative to the shaft 94 and the arm 195 so as to operate the fly 235 at the appropriate time.
In Figs. 1 and 2, 242 indicates the usual paper guiding fingers which are shown mounted on the slotted arms 243 that are secured by thumb nuts 244 to the receiving tray 240, thus to keep the paper straight on the tray. A brake lever 245 is connected by a shaft 246 with a crank arm 247 and connecting rod 248, lever 249 and link 250, with a brake shoe 251 that is adapted to engage the fly wheel 252 of one of the platen printing presses. Said printing presses are connected in timed relation with each other by the train 253, and said presses are connected by sprocket wheel 254 and sprocket chain 255 with sprocket wheel 100 and shaft 256 on which the sprocket wheel 100 is mounted, and which is also provided with sprocket wheel 257 to drive the sprocket chain 99. A web roll brake indicated at 258 is provided to prevent the web from racing.
In Fig. 1 two power belts 259, 259 are indicated for driving the presses 5 and 6 and two sprocket chains 255 and 255 are shown, one connecting the press 5 and the other the press 6 with a sprocket wheel 100 of the attachment, it being understood that a sprocket wheel be provided for each of the sprocket chains and that either chain may be thrown out of gear by clutches, the handles 260 of which are shown and that one of the gears in the train 253 may be removed and the sprocket wheel 100 driven by the sprocket chain 255 may be thrown out of action when it is desired to pass the duplicate web 2 through the attachment unprinted.
In practical use it is understood that the method of connecting the presses with the mechanism of the attachment may be varied within the judgment of the constructor, so that either or both of the presses may be run as desired.
In Fig. 23 there are shown one complete and two fragmentary sheets cut fromthe webs. The original and duplicate sheets 500 and 501 are printed to form the leaves of order books, there being four of such leaves to each sheet.
The practical operation of the machine will be understood from the foregoing.
To print the sheets for a book containing printed original and duplicate sheets the webs 1 and 2 from the rolls 3 and 4 will be carried through the printing presses and through the attachment to the pulling rollers as indicated either in Fig. l or Fig. 24 and then upon applying power to drive the mechanism the two presses and their mechanism will operate to produce and deliver the printed sheets onto the tray 240.
WVhen it is desired with the arrangement shown in Fig. 24 to omit the printing from the duplicate sheet the webs will be led through the attachment in the manner suggested by Fig. 25.
