POSED IMPRESSIONS This invention relates to printing presses and has specific reference to a press for color printing of graphic logs on long narrow strips of material to be printed.

It is a common practice now in the drilling of oil or other wells to keep a Well Log, which gives a graphic record in colored transcription of the different strata of earth penetrated in the drilling operation. The geological departments of the oil industries consistently use such logs. Heretofore, the procedure in making the logs is to use colored ink or pencil applied by hand to a base form printed on a long narrow strip of paper marked ofi in intervals of drilling depth. One size of form used comprises a strip of paper approximately five feet long and three inches wide lined transversely over the length of the sheet at one inch intervals each representing 100 feet of well depth. A inch wide strip runs along the left side of the log, and this strip is subdivided into inch wide spaces, each representing ten feet of well depth.

Several copies of the well log are usually required, each an exact duplicate of the other. However, rarely are more than 10-20 copies of the well log required. It will be seen, therefore, that accurately preparing these copies by hand would be a painstaking, tedious and time consuming process, while a conventional press andoperating it with suflicient accuracy for exact color registration would be prohibitive. Moreover, a conventional press, such for example as a proof press which is satisfactory for black printing, is inherently not sufiiciently accurate in operation to give overprinting registration necessary for color printing of the type discussed. Attempts to use color photography and colored typewriting processes have proved unsuccessful. In short, the hand coloring of well logs has heretofore been better and cheaper.

Therefore, it is a primary object of this invention to provide a printing press for a multicolor process on an elongated strip of material to be printed and capable of correct multicolor registration.

Another object of this invention is to provide a press for printing an elongated strip of material having a paper supporting matte associated with accurate collimating means and clamping means for holding the material to be printed immovably in place throughout its length to insure against travel of the material during successive overprintings.

Another object of this invention is to provide a printing press having a press roll which is geared to passover said material to be printed in non-slipping contact-so that successive colors may be printed on said material in correct color registration.

Another object of this invention is to provide a printing press for printing an elongated strip of material having at least one type holding chase in which the type is locked in position by lateral pressure so that the type will not move from its correct position during successive printings and so that vacant spaces may be left in the printing surface where desired.

Another object of this invention is to provide a printing press. having at least one chase in which the type is easily set and held in trans-' verse-cut slots.

Another object of this invention is to provide a printing press having two lift-out rollers which are readily removable to speed up the multicolor process and which whenremoved leave all the remaining rollers uncontiguous to facilitate cleaning.

Another object of this invention is to provide a printing press having an inking roller unit with contiguous rolls therein of different diameter so that each roll makes contact with its neighbor roll along a different line on each revolution to more evenly distribute ink and reduce roll wear.

Still another object of this invention is to provide a printing press for applying a multicolor process to anelongated strip of material to be printed which is easy'to set up for operationand in which corrections may be readily made.

With these and other objects in view, reference is made to the accompanying drawings and detailed description thereof which is set forth for the purpose of explaining the invention in its preferred embodiment, but which is not meant to limit the scope of the invention except as defined in the appended claims.

In its broadest concept this invention embodies a printing press for printing a multicolr well log in correct color registration on an elongated strip of material to be printed. Means are provided for correctly registering each strip of material on a matte on the press and further means are provided for locking the material in place along its entire length on the matte. Type which is. set in transverse cut slots in a chase to be used in the press is easily set and allows the chase and type to be locked in place by a' member exertin lateral'pressure along the entire length of the chase. provided with mechanism whereby it contacts the printing matte when moved in only one direction and whereby the roll rotates. at a peripheral speed equal to the movement along thematte to prevent relative movement of the'paper to the type. An inking roller unit is provided with readily removable lift-out rolls for quick color changes and contiguous rolls of different diameter to insure even distribution of ink'therein and means are included for alternately looking out the press roller unit and the inking roller unit as the matte is respectively positioned in a loading or a printing position.

Referring particularly to the drawingsFigures 1 and 2 show the printing press. In of'this invention in broken up longitudinal sections. An elongated frame ll acts as a support for the press. Standards or bearing posts l2, preferably of bronze, are spaced at intervals along one side ,1

of the frame to carry a round rail l3 which is journalled for rotation on said standards. A gear rack I4 is carried on a rail I which is on the other side of the frame and parallel to the round rail. Together the round rail and the geared rail form a track I6. A pressroller unit H. is mounted for movement along the track l6 and is parked at one end of the press on said trackwhenthat unit is not in operation. 7

An inking roller unit generally designated as A press roller unit is 23 is normally parked at the other end of the track from the press roller unit. This unit comprises a group of rolls and gears to explained in detail in relation to Figure 8 later on. A lockout 24 is fixed on the round rail to hold the inking roller unit in its parking position when it is not being used. Another lock-out Z5 is fixed on the round rail in opposite phase to lock out for the inking roller unitso that itmay be moved over the central portion of the frame when the lock-out 24 is in position to hold the inking roller unit back. Note that the lockouts do not obstruct the entirecircumference of the round rail, for when one lockout is turned downward, it leaves the rail free at that end of the track for the roller unit at that end to move along the frame.

Along the longitudinal center of the frame I! and between the rails of the track is a printing press bed. 26 for mounting at least one type carryin chase 2? as shown in Figure 5. A matte frame 28 having a matte 29 mounted therein is rigidly secured to and extends radially from the round rail to move with said rail as it is rotated. Ordinarily, the round rail is rotated in a 180 are so that the matte moves from a horizontal loading position at the side of said frame I l to a horizontal printing position over the bed 26. One or more arms 39 extend from the side of the frame H to support the matte when it is in the loading position.

The control mechanism A handle operated mechanism 3! is positioned at the end of the round rail where the press roller unit is parked to actuate the round rail. This mechanism as shown in Figure 3 comprises a housing 32 from which extends a crank shaft 33 on which is fixed a crank arm; 34 with a handle 35. A crank arm36 is fixed. to theinner end of said shaft 33. the crank arm 36 through a gear crank 38. The gear 31 engages a gear 39 which is fixed to the round rail I3. When the handle 35 is in the position shown by the dotted lines, the matte is in the printing position over the bed of the printing press. Also, the lookout 24 holds the inking roller unit in its parking space. When the handle 35 is in the position shown by the dotted lines, the matte is in the loading position on the extending plate. 30. In this position the look-out 25 will hold the press roller unit in its parking space and the inking roller unit may be moved forward over the bed 26. It is to be noted that the gear crank 38 is positioned on the gear 37 by a pivot stud 38' in such location that when the matte is moved from one extreme position to the other, it moves through its intermediate position quickly but slows down to ease into the extreme positions. gradually. This provision prevents wear and tear onthe matte and provides the conventional slow approach to the type.

The matte and printing material clamp Finger clips 45 arearranged along saidshafts at.

intervals to clamp a material to be printed in A gear wheel 31 is connected toplace throughout the length of the matte on both sides thereof. The matte 29 includes a sheet metal base 46 with a rubber covering 4'! for better receiving type impressions. Collimation pins or pegs 48 protrude from the rubber covering along one side of the matte at spaced intervals. The material to be printed is provided with holes along one side thereof to register with the collimation pins on the matte. Thus, all sheets of material to be printed placed on the matte will always be in the exact same position. With every sheet of the material to be printed placed on the matte in proper registration on the collimation pins and the finger clips lowered into contact with the material to be printed, every sheet will always be registered in the exact same manner on the matte and held throughout its length against movement out of such registration.

A toggle coupling 49 is located on the matte at the end thereof toward the inking roller unit and connects one rotary shaft of the matte with the other so that when one is turned to clamp down on the material to be printed the other will do so simultaneously. The coupling includes a crank arm 59 fixed to each shaft and a separate connecting bar 51 joining each crank arm to the opposite extremities of a centrally positioned plate 52 which is pivoted at its center 53 to the end plate 43.

On the end of the matte toward the extension plate 30, there is an end plate 54 journalling the ends of the shafts 44 as shown in Figure 10. The end plate 54 has an upward extension 55 through which passes a pivot bolt 56. A head 51 covers one end of said bolt and a cotter pin 58 in the other end holds the bolt against longitudinal movement. A latch 59 is carried by the bolt 56 in a slot 69 of the extension 55. A spring 59', shown in Figure 12, forces the bottom of the latch out from the slot 60. The latch is serrated on its upper edge for finger control if desired. A latch handle BI is fixed to the end of the inner shaft 44 by a positioning screw 62 so that the shaft will turn when the handle is moved. The latch handle is slotted to receive an angular latch key 63 which is pivoted within the slot at 64 and has a projection 65 beyond the slot for hand operation. A spring 63 pushes the key to extend it out of the slot toward the latch. As shown in Figure 12,..the key 63 fits into a recess 66 within the edge of the latch 59 to lock the latch handle in place. When the latch handle is down as in the locked position the finger clips on the shaft 44 are clamped down against the matteand a material to be printed placed thereon. The latch handle turns the inner shaft to which it is attached and that shaft in turn actuates the toggle coupling to turn the other shaft to the clamped position.

Though the material to be printed clamping mechanism just described can be operated by hand, it can also be operated automatically. The plate extension 30 of theframe H is bolted to the frame by a bolt 81. An angular control member 68 is pivoted to the extension 39 at 69 for limited movement thereon. The control member 68 has an angular surface on its extreme end at 10. A spring H gives resiliency to the control member when the member is contacted.

When the matte is returned to the loading position from the printing'position, it swings in an are so that the latch 59 contacts the end of the control member 68 at the end 10. A forward sloping edge 12 of the latch 59 slides along the end and forces the latch backinto the recess against the spring 59'. The latch is thus moved away from the key 63 so that the latch handle is free. Since the key 63 protrudes from the'inner side of the latch handle, the key is caught on the end 10 as the matte swings further down into the loading position. Thus the latch handle is suspended to keep the shafts 44 turned to, a position which unclamps the clamping fingers thereon. To reclamp the clamping mechanism, the key 63 is actuated by hand operation of the projection 65 to remove the key from the surface end 10 of the control member. The latch handle then falls to the position shown in solid lines in Figure 10, the clamping position.

The press roller unit 5 The press roller unit shown in Figures 3 and 4 is contained in a housing 72. A press roll 13 is suspended within the housing on a pair of pivoted side plates 14 on either side thereof. An axle 15 runs through the roll 13 and is journalled in the side plates. The housing has a front gear wheel '16 and a rear gear wheel 11 on one side and normal Wheels 15 and T! on the other side. The front wheels are joined by an axle l8 and the rear wheels by an axle 19. The rear gear wheel 1'! drives a gear 89 on a stud shaft 8|. Another gear 82 on the stud shaft drives a gear 83 on the press roll axle to turn the press roll. These gears are arranged in a ratio such that. the press roll will roll in non-slipping contact over the back of the matte as the press roller unit is pushed forward.

The side plate 74 on the gear side of the unit is anchored on to the end of the stud shaft 8| The stud shaft is supported on its inner end by a positioning plate 84 which is bolted to an upper bar 85 and a lower bar 86. On the normal wheel side of the unit the side plate 14 is anchored by a through bolt 8'! and a spacer ring 83 to the side of the housing. A lifting bar 89 is attached to the forward end of each side plate 14 to raise same. The upper end of each bar 89 is connected to a crank arm 90 which is fastened by screws 9| to a bar 92. An operating lever 93 with a knob 94 is attached tothe central portion of the bar 92 and extends through a slot 95 in the top of the housing.

The inking roller unit The inking roller unit 23, as shown in Figure 8, has a carriage 99. The gears for driving and operating this unit are all arranged on one side thereof. A drive gear 91 is carried by a transverse axle 98 at the rear of the carriage. A wheel 99 on axle 98 as shown in Figure 7 supports the inking roller unit on the rail [3. A gear I99 is fixed to the axle 98 transmitting power from gear 9'! to operate the rolls of the unit as the inking roller unit is pushed forward on the track. The gear Illll meshes with a supply roll gear "H, which in turn meshes with a transfer roll gear I02. Gear I02 engages a large distribution roll gear I03 which drives a forward inking roll gear H9 and a rear inking roll gear III at the bottom of the carriage. An eccentrically mounted gear H2 at the front of the inking roller unit is normally disengaged from the gear rail, but is engaged with the gear rail when the unit is pulled back to its starting place to raise the inking rolls from the type during the initial distribution of ink on the rolls and during cleaning. The axle I I3 which carries the idler H2 carries an eccentric idler wheel and handle (not shown) on its other end.

ampere Figure 2-1 shows how thegears are supported by a longitudinal plate H4= held in spaced relation to the side of the carriage 98 byspacers- A supply roll H9 carries the ink initially and transfers it to a transfer roll I25 which places. The latter. roll ink on the distribution roll IZ I distributes ink tofront and rear inking rolls I22 and I23 respectively for inking the type. The supply roll andthe distribution roll are also lift-out rolls designed-for easy removal forquick operation of the multicolor process. In Figure 9 one of the lift-out rolls has a fixed axle I24 borne by bearings I25 in the carriages 96 and the plate H4. A removable axle I26 is connected at one end for rotation with the fixed axle by a multi-jam coupling I21. The other end of the axle I26 is held in a detent I23 within the carriage. A steel ball I29 is forced outward from a tapered hole I30 by a spring I3I whichv isheld by a screw 132. The ball is greater in diameter than the end of the hole so that it cannot come out. The end of the axle I26 is provided with a curved surface which engages a" portion of the ball to hold the axle firmly but also so that it can rotate. By lifting on the axle I25 at the end toward the detent it is easily snapped out of the inking roller unit. When both lift-out rolls are removed, none of the rolls remaining in the unit are touching one another. This enables easy cleaning, saves ink, and in addition, prevents flats in the rolls when the unit is out of use. Note also that all gears remain engaged at all times even if the lift-out rolls are removed in order to expedite cleaning and prevent damage to gears in handling. All rolishave the same diameter as the gears which drive them so that they will contact each other without slipping against one another.

The type chases The type and method of setting same for the printing press of this invention is shown in Figures 13-17. The chase block 27 of the color printing chase is preferably made of hard aluminum alloy into which are cut transverse slots I33. Steel spacers I3 are set into the slots. Clips I35 are punched into the steel spacers to secure them in a vertical position within the slot. A type slug I36 is used on the color chase. For printing spaces for descriptions on the log, numerals and transverse lines marking the 100 foot sections are printed by-a type slug I3? which is employed in a description chase I38. Linotype slugs bearing the descriptive word of the well sample taken are inserted between the adjacent slugs I3! with furniture spacers inserted to fill in the blank spaces andhold the descriptive word slugs in firm printing position. Since no over-printings of the description chase are required, accurate registry of thev words is not necessary. When printing in color, a furniture spacer occupies the space of the description chase.

Fig. 1'7 shows how the type I35 is adapted to give greater variation to the log by having symbols cut in its printing surface, and how the printing surface of the type may be partly cut away to show degrees of symbolizing. The type slugs are made to have some clearance between the spacers so that they. may be set more quickly. A black log chase for printing the division lines between- :back to its parking. space.

The chase lock A unique chase lock has been devised to lock these-chases in the bed of the pressframe. In Figures 6 and '7, the bed has the movable side I40 and a stationary side I40. Soft material- I4I lines the inside top andbottom of the movable side. Plates I42 are positioned'at intervalsalong the outside of the movable side of the bed; A connecting arm I43 joins the plate I42 with a crank arm I44which is fixed to a pivot shaft I45. The shaft I45- extends through the side of the frame II and has another crank arm I46 on its lower end; A- connecting rod I47 connects all the crank arms I45 along the side of the frame II to actuate same in unison as a handle I48, as

shown in Figure l, is moved to-apply the chase lock. Thus all chases and any furniture spacers which may be used are locked in one operation.

Even pressure is-applied throughout the length of" the chases, and the individual type slugs are locked in place between the movable and stationary side of the bed. In this manner the type is not dislocated by longitudinal compression of the type from one endof the elongated chase to.

In accordance with the invention, the chasesare compiled and thenthe appropriate chases areplaced into the bed of the press-and locked. The appropriate color'of ink isapplied to the supply roll of the inking roller unit. The inking unit is moved backand. forth out of. contact with the type and the ink isdistributed evenly on the inking rolls due to the different diameter of the rolls.

The material to be printed or paper which has been appropriately perforated is placed on thematte in proper registration over the collimation pins andithen the paper clamp looks it in place. The inking. roller unit is broughtinto contact with the type and rolled. back and forth over it. :once.. Theimatte is closed and the press roller swung. back to the loading. position,v the paper clamp is automatically opened on. both sides of' the paper and the log paper'can be removed. The operation is then repeated for other printings. It isto be noted that by cutting the paper to be used withthegrainrunning. the long way and by per.- forating only the amount of paper to be printed atone run, greater. accuracy in collimating' the paper is achieved.

From the foregoing-it is apparent that the press of. this invention ensures themost correct color regist-rationin' the printing. of a multicolor log on' an elongatedistrip of) material to b'e'printed. Not only is the material to be printed carefully registered'and clamped'in place throughout its length, but the type is held firmly. against dislocation throughout its length. as well; In. addition, the press roll is incontact withthe matte while moving. in: only one. direction toavoid travel of. thethe ten-foot. well depth. intervals, and also for. 75. matte oventhe type;

When the matte is.

' Furthermore, this printing press enables fast operation of a multicolor process. Not only may the type be set quickly, but spaces not needed may be left vacant. Also, the paper clamp is partially automatic to speed up the loading of paper. The lift-out rolls are readily interchangeable and the ink rolls are easily cleaned.
