In broad terms, my machine comprises a suitable supporting base upon which is mounted a reciprocable platen upon which an object having a surface to receive a superficial coating may be placed. On the base is mounted a plurality of separate reservoirs 'in which fluid coating materials of different types or colors may be placed, and reciprocabl-y mounted on the base, adjacent the platen, is an applicator frame which carries a separate applicator for each of the reservoirs. Flexible means is provided connecting each reservoir withits respective applicator so that the nuid coating material in they reservoir will be conducted to. the applicato-r. Each of the applicators has a 4controlled port therein through which the fluid coating material may flow. Power means is provided for moving the platen so as to bring the surface of the object carried .thereby into juxtaposition with the applicator ports and means is provided for maintaining these relative positions of the object and applicators during a predetermined interval of time.

Means is provided, operative during the said interval of time, for primarily opening the ports of the applicators to allow the fluid coating material therein to contact the surface of the object carried by the platen and fo-r secondarily moving the applicators along said surface of the object so that the coating material will be deposited on the object surface in a layer of appreciable area. Means is provided, associated with each applicator for varying the thickness of the individual coating being applied thereby and means is also provided for varying the relative movement of theA applicators and the surface of the object so that the area receiving the coating may be selectively varied. After the object has received its coating, the platen and applicators are cycled back to their starting positions so that another object to be coated may be placed on the platen. Means is provided, associated with the power means, for limiting the cycles of the moving parts of the apparatus.

In greater detail, the machine comprises a horizontal table I3 which may be provided with a plurality of depending legs I4 by means of which the table may be supported in an elevated position above the surface of a floor or other supporting surface. Formed in and extending through the table I3 is a rectangular opening I5 in which is mounted for vertical movement a horizontal complementary rectangular platen I3 on which the object to be coated, such as the sheet of paper I1, may be placed. Suitable stops which may be ridges or pins I1 engage the edges of the sheet I1V to position it and prevent shifting thereof on the platen.

Means is provided for moving the platen I6 in a vertical direction, between elevated and depressed positions. Disposed below the table I3 and extending transversely across the opening I is at least a pair of shafts I8 which are journaled in suitable bearing brackets I9 secured by bolts 2I to the lower surface of the table adjacent the longitudinal edges of the opening, each having fixed for rotation therewith one or more disk cams 22 which engage the lower surface 23 of the platen I6. Each of the shafts has fixed for rotation therewith a sprocket 24 which meshes with an endless chain 26 so that the cams 22 are connected together for synchronous rotation. It will be seen that when either one of the shafts I8 is rotated, preferably in a clockwise direction, the successive surfaces of the cams coming into engagement with the lower surface 23 of the platen will be first, the lifting face 21, which raises the platen to the upper limit of its travel as shown in Figure 3; second, the upper dwell face 28, which is arcuately concentric with the axis of rotation of the cam and which maintains the platen at its elevated limit of travel during substantially 180 degrees of rotation of the cam; third, the lowering face 29, which is reversely complementary to the lifting face 21 and which permits the platen to descend to its lower limit of travel; and finally, the lower dwell face 3| which is also arcuately concentric with the rotational axis of the cam and which retains the platen at its lower level until the cycle is repeated and the lifting face 21 engages the platen to again lift the latter.

Power means is provided for rotating the shafts I8, to reciprocate the platen, and means is provided for limiting the rotation of the shafts to unit cycles. the table I3 is a motor 33 which drives, through a suitable speed reducing gear 34, a power shaft 36 which is divided into a pairof independently Mounted on an extension 32 of rotatable sections, one of which is journaled in the reducing gear housing 34 and the other of which is journaled in suitable bearings 31 mounted on the table extension. A clutch 38, which is preferably the positive jaw type, is provided for connecting the two sections of the power shaft 36 for rotation together. As is best shown in Figure 3, a jack-shaft 39, journaled in suitable bearings secured to the lower surface of the table extension 32, is positioned below the power shaft 36, and the respective shafts are provided with sprockets 4I which mesh with an endless chain 42 so that the shafts are connected for rotation together. Another endless chain 43, which engages sprockets secured for rotation, respectively, with the jackshaft and one of the camshafts I8, connects the latter shafts for rotation together.

The clutch 33 is preferably of the selectively engageable type and is provided with an operating lever 44 which, when depressed, withdraws a pin 46 from engagement with a shoulder 41 formed on the head 48 of a latch pin 49 reciprocally mounted in bearings 5I carried by one section of the clutch. Release of the latch pin permits one end thereof to be projected by a spring 52 into a notch 53 which thereby locks the two sections of the clutch together and consequently connects the two sections of the power shaft 35 for rotation together. This, of course, causes the camshafts I8 to rotate and to cycle the platen I6 between its depressed and elevated positions. After the clutch makes one revolution, a sloping surface 54 on the head 48 of the latch pin 49 engages the lever pin 46 and causes withdrawal of the latch pin from the notch 53 thereby disengaging the two sections of the clutch and stopping the cycle of the platen when the latter is in its lowest depressed position.

Mounted by bolts 56 on the upper surface of the table I3, and positioned in spaced pairs adjacent the transverse edges of the table opening I5, are slide bearing blocks 51 on which is slidably supported, for movement horizontally across the surface of the platen I6, a coating applicator slide comprising spaced parallel side rails 58 connected together adjacent their ends by transverse cross members 59 and having integral eX- tensions 6I provided with horizontally directed top and bottom flanges 62 and 63, respectively. Secured by mounting screws 64, to the cross members 59, is a plurality of applicator support members each comprising a U-shaped strip 66 of exible metal having transversely alined and longitudinally spaced pairs of apertures 61 therein as shown in Figure 9. Coating applicators, generally indicated by the numeral 38, are removably mounted, as will be presently explained, in each pair of the apertures 31. The number of sets of apertures 61 provided longitudinally of the applicator support members determines the number of vertical columns 69, Figure '1, which will be imprinted on the sheet or color card I1, and the number of applicator support members provided transversely of the applicator slide determines the number of separate vertically spaced imprinted areas which will appear in each column 69.

Each of the coating applicators, as is best shown in Figures 4 and 5, comprises a body 1I having in opposite sides thereof grooves 12, which are complemental, in cross-section, to the strips of the applicator support members 63, having pins 13 mounted therein which are engageable in the apertures B1 of support member strips. Since the strips of the support members are flexible. and may be forced' apart, to disengage the pins 13 from the apertures 61, the applicators may be readily separated from the support members' for replacement or cleaning. Extending vertically through the applicator body 1| is a rectangular' bore 14, and secured to the body 1| at and concentric with the upper end of the bore is a tubular nipple 16. ToV the nipple 1-6 is attached one end of a flexible conduit 11, which may conveniently be rubber tubing, the other end of the conduit being connected to a suitable discharge nipple extending from the bottom of a preferably cylindrical hopper 18 carried on an elevated platform 19 which is supported, by legs 8|, on the table I3. A hopper 18 and conduit 11 is supplied for each of the coating applicators used, and in the hoppers may be placed considerable quantities of the various types of colors of coating materials, to be applied to the sheet or color card I1, which material may flow through the conduits 11 into the bores 14 of the applicators.

Means is provided at the lower end of the applicator body for permitting coating material contained in the bore 14 to flow therefrom to be deposited n the surface of 4the sheet or color card I1, and means is provided for controlling the flow of said coating material. Formed 0n and extending horizontally from one transverse side of the applicator body 1I, adjacent the lower end thereof, is a pair of parallel lugs 82, `each of which, on the inner face thereof confronting the other, is provided with horizontally alined ,guide grooves 83 which extend transversely ,of and into the bore 14. One transverse wall of the applicator body bordering the bore 14 is cut away to a plane coinciding with the upper side of the guide grooves 83. A sheet metal gate 84 is slidably mounted in the guide grooves and has a lip 86 which extends angularly downwardly to terminate in the plane of the lower horizontal end of the applicator body and in contiguous relation to the forward edge of the bore 14 which edge may be termed the leading edge of the port. A lever 81 journaled on a pivot pin 88 carried by the applicator body 1| has its lower end extending through an aperture provided adjacent the rear edge of the gate 84 so that movement of the lever will cause the gate to move in the guide grooves 83 and to create a discharge port for the bore 14 defined by the parallel side edges and the forward transverse edge of the lower end of the bore 14 andthe lowermost edge of the lip 86. A spring 89 engaging, `atit's'respective ends, the lever 81y and the applicator body 1| serves to forcibly return the lever toa normal `position of rest in which the port of the applicator bore 14 is closed.

When the platen is raised to its uppermost position, the upper surface of the sheet I1 will contact the lower endl surface of the applicators carried by the applicator slide. It will, therefore, be seen that if the gate 84 is moved toopen the applicator port, the coating material contained in the applicator will come into contact with the surface of the sheet I1. It will be noted, upon careful examination of Figure 5,I that the guide grooves 83 lie at a slight angle withd respect to the horizontal so that when the gate 84 is moved by the lever 81, the lowermost edge of the gate will be gradually elevated thereby creating between it and the surface of the sheet I1 a gap having a vertical dimension which depends upon the degree of movementofthe gate ,from its closed to its fully opened position. It will be seen that with the gate open, movement of the applicator across the sheet will draw a stripe of the coating material on, the sheet and that the thickness of the coating will be determined by the extentto which the gate is opened.

Means is provided, operative when the platen and the sheet I 1 carried thereon are in their uppermost position, for primarily operating the levers81 to open the applicator ports and secondarily for moving the applicator slide to move the applicators bodily across the surface of the sheet. Mounted on and fixed for rotationwith the power shaft 36 is a disk cam 9| having a cam groove 92 thereinV engaging a cam roller 93 carried by and journaled on one end of a connecting rod 94 which is supported and axially slidable in a bearing 96 mounted by bolts 91 on the table I3. The other end of the connecting rod is provided with a clevis S8 having in the spaced parallel side arms thereof vertically elongated slots 99 in which is slidable a horizontal pin ||l|` carried at the distal end of a lever |02 fixed for rotation with a shaft |03 which is journaled in bearing brackets |04 extending from a cross-member |05 which ties together the parallel side bars |86 of a valving slide mounted on and slidable relatively with respect to the applicator slide. The slidable mounting of the valving slide is effected by clips |81 which are secured to the side bars |86 by bolts I 68 and extend downwardly along the inner sides of the side bars 58, and the slides are held against relative vertical displacement by pins |89 which are iixed in the side bars 58 of the applicator slide and which engage elongated slots III provided in the clips |81. The valving slide is provided with separate trip bars II2, for each transverse set or row of applicators, which are secured at their ends to the side bars |86 and are provided with adjustment screws I|3 which, when the valving slide is moved, engage the applicator levers 81.

Fixed on the shaft M3 and extending toward the applicator slide is a centrally positioned valving slide latch lever I E4 and a pair of applicator slide latch levers I I6. Both the lever ||4 and the levers IS have at their distal ends, respectively, downwardly directed spurs I I1 and IIS. Mountu ed medially of the ends of the cross-member is a latch bolt block ||9 having a recess |28 therein and an axial bore |2| in which is sildably mounted a valving slide latch bolt I 23. The latch bolt |23 has at its upper end, and positioned within the recess |28, an enlarged head |24 between which and the bottom of the recess is interposed a coil spring |26 which normally urges the latch bolt upwardly toward the upper end of the recess. An annular collar |21 threaded into the block ||9 engages the head |24 of the latch bolt and limits the upward movement of the latter, and the opening in the center of the collar is to allow admittance of the spur |I1 into the recess |20 to contact the latch b-o'lt head for the purpose of depressing the latch bolt. A. latch bolt aperture |28 provided in the cross-member 62 of the applicator slide is positioned to come into axial alinement with the latch bolt I 22 so that the latter may pass into the aperture |28 and thereby lock the valving slide andthe applicator slide together,

As will be most clearly seen in Figure 5, blocks |29 are secured Vto each of one pair of the slide bearing blocks 51 below the bearing plates` Isl thereof, and apertures |32 bored vertically through the blocks |29 and ybearing plates |3I, and axially registrable with latch apertures I 33 provided in the ange 63 of the applicator slide, slidably receive U-shaped applicator slide latch bolts |34 each being provided with upwardly directed arms |36 having shoes |31 mounted on the upper ends thereof and springs |38, secured at their opposite ends, respectively, to the bearing blocks 51 and the latch bolts |34, resiliently urge the latch bolts in an upward position.

At the start of an operative cycle, the platen I6 is at the lowest level of its travel resting on the lower dwell face 3| of the cams 22, and the combined applicator and valving slides 58 and |06 are about midway of their recovery stroke to the left-hand end of the machine. A sheet of material I1 to be coated is now placed on the platen I6. The operator now depresses the operating lever 44 which engages the power shaft clutch and connects the power shaft for rotation, through the reduction gear 34, with the drive motor 33. As the power shaft rotates, rotation will be imparted to the cams 22 through the chain drive to start the platen I6 upwardly, and rotation will also be imparted to the disk cam 9| which will drive the applicator and valving slides toward their aforesaid left-hand limit of travel. This limit is reached just as the upper dwell surfaces 28 of the cams engage the underside of the platen which is now at its uppermost position with the sheet I1 engaging the lower end of each of the applicators 1I. Continued rotation of the power shaft will cause further rotation of the disk cam 9| which now starts moving the connecting rod 94 toward the right as indicated by the arrows |39 of Figures 2 and 8. The elevated position of the platen will not be altered by continued rotation of the cams 22 sincev the platen is resting on the concentrically arcuate upper dwell surfaces 28.

Referring now to Figure 2, it will be seen that when the connecting rod 94 starts its motion toward the right-hand end of the machine, the lever |02 will be urged upwardly thereby imposing a downward force on the latch levers I I4 and |I6. This will swing the lever ||4 downwardly so that the spur II1 enters the recess |20 and contacts the head |24 of the latch bolt |23 depressing the latter until the lower end thereof contacts the upper surface of the cross-member |05. The arrangement of the parts is such that the spurs I|8 of the latch levers-| I0 do not descend quite far enough to contact the shoes |31 of the applicator slide latch bolts |34 which are engaged in the apertures |32 and, therefore, lock the applicator slide to the table.

As soon as the latch bolt |23 bottoms, the

horizontal movement of the connecting rod 94 will be imparted to the valving slide thereby causing the latter to move toward the right until the latch bolt |23 registers with and snaps into the aperture |28 thus locking together the valving and applicator slides. This primary movement of the valving slide and the engagement of the latch bolt |23 in the aperture |28 causes two distinct actions. First the movement of the valving slide moves the trip bars ||2 to press the levers 81 toward the applicator bodies thereby moving the respective applicator gates 84 to open the applicator ports so that the coating material in the several applicator bores 14 will come in contact with the surface of the sheet. Secondly, the spurs I|8 which were held out of contact with the latch bolt shoes |31, by the bottomed -latch bolt |23, will now descend to engage the shoe thereby depressing the latch bolt |23 and causing the latter to unlock the applicator slide from engagement with the bearing plates |3I. Since the valving and applicator slides are now locked together, and since the applicator slide is freed, they will be moved by the connecting rod as a unit thereby causing the applicators to be moved linearly over the surface of the sheet |1. This Will cause the coating material issuing from the port of each applicator to be deposited in short stripes |42, as shown in Figure '1, thus forming the separate coating or color areas which are the equivalent of the familiar adhesively attached color chips found on the color cards or charts distributed to dealers or consumers by paint or other coating material manufacturers.

As heretofore explained, the thickness of the color coatings, and consequently the density of the color, depends upon how far the individual ports of each applicator is opened, this being controlled by the individual adjustment screws I|3 provided on'the trip bars I2 for each applicator. It is thus possible to regulate the'machine so that only a very thin coating of a material possessing good covering qualities is deposited in one area of the sheet I1 while a considerably thicker coating of a material having poorer covering power is deposited in another area thereof.

After the disk cam 9| has rotated to move the interlocked valving and applicator slides as far as they will go to the right, as viewed in Figure 3, which is the degree of throw of the cam and which incidentally governs the length of each coating stripe |42, the cam will start on its recovery cycle thereby causing the connecting rod 94 to start recovery movement to the left as indicated by the arrow |43 of Figure 9. This immediately causes the lever |02 to be swung downwardly thereby raising the spurs II1 and I I8 out of engagement, respectively, with the head |24 of the latch bolt |23 and the shoe |31 of the latch bolt |34. As soon as the latch bolt |23 is released, from the aperture |28, the collective action of the springs 89 of the applicatorswill forcibly cause the valving slide to be shifted to to left relative to the applicator slide, vas shown in Figure 9, thereby allowing all of the applicator ports to fully close simultaneously thus cutting off the contact of the coating material in the applicator bores 14 with the surface of the sheet I1.

The timing between the components of the drive mechanism of the machine is such that immediately following the release of the valving slide, to effect closing of the applicator ports, the platen and the sheet I1 carried thereby will start to move downwardly away from the bottom of the applicators, directly after which the continued movement of the connecting rod 94 will cause the applicator slide to be moved to the left to the point marking the start of the operative cycle as described above. The power shaft 36 will now have made one complete revolution and the clutch will become disengaged, in the manner previously described, thereby disconnecting the shaft 36 from the drive motor 33. The coated sheet I1 may now be removed from the platen I6, replaced with a blank sheet, and the cycle of operation repeated by depression of the operating lever 44.

In Figure 12, I have shown means whereby the length of the color stripes |42 may be varied. It will be seen in Figure 3 that since the throw of the disk cam 9| is fixed and the length of the connecting rod 94 is invariable, the travel of the applicator slide will be between xed limits,

equal to the throw of the cam, which will determine the length of the stripes |42. In the structure of Figure 12, I provide a two-piece connecting rod, the main section |46 thereof, at the end adjacent the slides, being provided with a diametrically reduced shank |41 which is internally bored and threaded to receive the threaded stem |48 provided with an enlarged head |49. The clevis 98 is provided with an integral tubular sleeve which is in slidable telescopic engagement with the shank |41 and is provided with a pair of longitudinally extending slots 52. A pin |53, passing transversely through and secured in the stem head |49 enters and is movable in the slots |52. It will be seen that by removing the pin |0| from the lever |02, the clevis may be disengaged from the lever and rotated thus causing the stem |48 to be rotated so that the stem head |49 may be positioned at various distances from the end of the shank |41. This will, of course, position the pin |53 at various distances from the right end of the slots |52. When a solid connecting rod is used, as shown in Figure 3, the movement of the applicator slide starts very shortly after the connecting rod starts to move toward the right. However, if the telescopic connecting rod of Figure 12 is used, the main section |46 of the connecting rod will move to the right until the pin |53 engages the right end of the slots |52 before motion will be imparted to the clevis 98 and, therefore, before motion is imparted to the valving and applicator slides. It'will be seen, therefore, that this lag or lost motion will be deducted from the amount of throw of the cam 9| thereby producing a stripe |42 having a length which is less than the maximum obtainable with the solid connecting rod.

It will be seen from the foregoing detailed description of my invention that I have provided a machine of the class described which is very simple in construction; which may, by the simple expedient of manipulating the several adjustment screws I3, be quickly adjusted to vary the thickness of the individual coatings applied to the separate areas of the sheet |1; that this adjustment may be accomplished even though the machine is in operation; that the improved applicator is capable of making clean-cut deposits of coating material without any wastage of the latter; that the applicators may quickly be removed from the machine for cleaning, thus materially reducing the set-up time necessary to effect rearrangement of the colors deposited on the sheet |1;.and that although a large number pf separate color stripes |42 are grouped together, the mechanism necessary to produce them is extraordinarily compact thus rendering the machine capable of occupying only a small amount of floor space. In addition to the above features, the machine may be operated at high speed, the output being governed by the rapidity at which the operator can replace. the coated sheets with blank ones.

It will further be observed that the applicators are of Vsuch character and so supported that a plurality of stripes may be applied thereby to a sheet with very little space between the stripes. This is an important consideration from the point of View of economy of production and compact-ness of display.
