.13 Claims- (c1. 101-124) This invention relates to improvements in re istering devices for multicolor printing.

It is an object of the invention to provide'a registering device for multicolor printing whereby the articles to be printed are rotated until they assume the desired rotary position for commencement of the printing operation and are then gripped and held immovable during their passage from registering to printing position and until commencement of the printing operation actually occurs, thereby eliminating the possibility of anyslight rotary movement of the work that otherwise might take place, particularly if the weight of the article to be printed is slightly unl5 evenly distributed, between registration and the commencement of the printing operation.

Another object'of the invention is' to provide a registering device for multicolor printing wherein a printing frame is reciprocated for printing 20. and is moved substantially at right angles from its path of travel as it approaches each extremity of its stroke; and wherein means coaot with the printing frame for releasing the grip upon the article to be printed as the frame is returned to its position for reciprocation thereby permitting the article to rotate freely in contact with theframe.

A further objectof the invention is to provide such a registering device including a special elec-v tric control means by which the articles are successively registered and held immovable, which electric control means is cut out by movement of the frame back to itsposi-tion for reciprocation.

Having thus briefly and broadly stated some of the objects and advantages of the invention I will now proceed to describe an embodimentthereof with the aid of the accompanying drawings, in which? Figure 1 illustrates a side elevation of the in vention and a portion of aprintingmachine to which it is applied. Figure 2 is an enlarged sectional view takenon the line 2-'-2 of Figure 1, and

Figure 3 is an enlarged section on .the line 33 I of Figure 1;

Figure 4 is a wiring diagram.

Referring to the drawings, l designates a portion of a stand of a convention-a1 printingmachine upon which a carriage 2 is reciprocated by a connecting rod 3 mounted upon a crank 4 on a shaft 5 which is turned in any preferred manner .not shown. Mounted on both sides of the stand I are lugs 6 in which opposed pairs of stops 1 are provided. Carried by the carriage 2 are .two par- .allel rods 8 the axial alignment of which coinride with the direction of movement of the carriage. Formed in the rods 8 are cam slots 9 to receive the lower extremities of pins III which extend downwardly from a printing frame I I, which is supported by the carriage for reciprocation 6 Q therewith. As the carriage approaches each ex- .tremi-ty of its travel the rods 8 strike one pair of stops 1 and consequently their continued movement with the carriage is arrested. Then continued movement of the pins III with the printing 10 frame II and carriage 2 moves the said pins out of the cam slots 9 and raises the frame As the carriage and frame commence their return stroke and the rods are moved away from the stops 1 balanced springs l2 provided around the 15 extremities of the rods return the latter to their normal positions with'respect to the carriage 2 and pins lllshown in Figure 1. The pins then drop back into the cam slots 9 and the printing frame H is again lowered to its normal printing 20 position. Fixed on the stand-l is a suitable switch 34 having an upwardly extending operating arm 35 laterally from which a roller 36 projects which rests upon the top of the frame ll. Consequently as the latter is raised and lowered 25 the switch is actuated by movement of the arm 35 in a manner hereinafter described.

' Mounted upon the stand I and extending transversely of the path of movement of the carriage 2. and beneath the latter is a shaft l5 mounted 0 v for intermittent rotation-as shown in my co-pending application Serial No. 219,014. Fixed upon the shaft l5 are two opposed carrier plates l6 and i1. Radially mounted upon the carrier I 6 are a plurality of chucks l8 which are inwardly urged by springs l9, and'mounted upon'the carrier l1,

each opposite one of the chucks l8, are other chucks 20. Each opposed'pair of chucks l8 and 20 are intended to support an article A to be printed, moreover the chucks and the ar- 40 ticle between them are normally freeto turn so that the said article may be rotated to the Position it is to assume for commencement of the portion of the structure.

Provided around the outer periphery of the carrier l1, and preferably supported in annular insulated grooves formed therein, are two parallel sets of segmental contacts 24 and 25. Each segment of each set extends through substantially 90 and around like portions of the carrier periphery, by which I mean that the ends of the segments of the two sets are disposed in transverse alignment. Suitably mounted upon a bracket 26, supported by the stand I, are brushes 28 and 29 which wipe the segments 24 and 25 respectively in turn as the-carrier |1 rotates, and mounted upon a similar bracket 21 are brushes 38 and 3| which also wipe the segments 24 and 25. Between adjacent'pairs of segments 24, or 25, insulation 32 is provided by which each adjacent pair of segments is sufliciently spaced that no brush can be in contact with more than one segment at a time. Each of the segments 24 is connected with one extremity of the winding of one of the electro-magnets 22, and each opposed segment 25 is connected to the opposite extremity of the winding of that magnet by connections 33 and 31 respectively.

Supported for rotation by the stand I is a stub shaft 38- having a friction disc 39 thereonwhiche.

contacts the periphery of each chuck 26 in turn when the latter reaches a predetermined position and rotates it when it is free to turn. The shaft 38 is provided-with suitable means for rotating it as for-instance a sprocket wheel 40 over which a chain 4| passes which is driven from any suitable source-not shown.

Mounted on the stand I is a bracket 44 which carries a phototube 42, and suitably supported, as from the shaft I5, is a light source 43. When an article A supported between two chucks l8 and 20 is so positioned that its chuck 26 is in engagement with the friction disc39 it is interposed between the phototube 42 and the light source 43, so that when the said article or bottle A has been turned by the disc to its desired rotary position an electric circuit about to be described is closed through a phototube relay, and the magnet 22 which cooperates with that chuck 20 by which one extremity of the article is held is energized; then further rotation of that chuck and the article held thereby is prevented.

' I will now describe my electrical control means with4the aid of the wiring diagram shown in Figure The electrical system consists of the following parts already mentioned, namely the phototube 42, the switch 34, the electromagnets 22, the segmental contacts 24 and 25, and the brushes 28, 29, 30 and 3|; and in addition the amplifying tubes 45 and 46, a thyratron or other gaseous tube 41, resistors 48, 49, 50, 5|, 52, 53, 54, 55 and 56, condensers 51 and 58, a voltage regulator tube 59, sources of power 68 and 690, a neon-tube 6|,

and potentiometers 63 and 64.

. The phototube 42 is connected by a lead 10 to the grid of the amplifying tube 45, and a lead 1| extends from the plate of the latter to the grid of the second amplifying tube 46. From the plate of this second amplifier a lead 12 extends through the condenser 51 and resistor 56 to the grid of the gaseous tube 41. From the cathode of the latter a lead 13 extends to, the binding post G and from the post a lead 14 is connected to one side of the switch 34. The opposite side of this switch is connected by a lead 15 to the binding post C and from this lead a wire 15a also extends to the is not believed necessary to further describe this brush 29 which wipes the segmental contacts 25 as the carrier l1 rotates. The brush 28 which is in-the circuit with the brush 29 is connected to the latter through each of the electro-magnets 22 in turn as the shaft l5 turns. From the brush 28 a lead 16 extends which is connected to the binding post D and fromthe latter through leads 11 and 99 and through the resistor 52 to the negative side of the source of power 60; and another lead I8 extends from the post D to the neon tube 6|.

The brush 39 which wipes the segmental contacts 24 is connected by a lead 19 to the binding post F and from the latter by a lead 86 to the resistor 59 and from the latter through leads a and 99 also to the negative side of the source of power 60. The brush 36 is connected through one of the magnets 22 to the brush 3|; from the latter a lead 8| extends to the binding post E. This binding post is connected by a lead 82 to the plate of the gaseous tube 41. The binding post G is connected by a lead 83 to the positive side of the source of power 69 and also to the adjustable resistor 55, and from the latter a lead 84 extends through the resistor 5 IV to the lead 10. From this lead 84 a connection 84a is made to the potentiorneter 63 and a second connection 84b to the cathode of the voltage regulator tube 59. The plate of this tube is connected at 85a to a lead 85 which extends from the phototube 42 to a. lead 86 connecting the adjustableresistor 55 with the potentiometer 63. From the lead 84, which is grounded to the casing of the instrument as indicated at 81, a lead 88 extends to the negative side of the source of power 60a, The cathode of the tube 45 is connected to the adjustable resistor 64 through a lead 89. A lead 90 extends from the lead 1| through the resistor 54 to a lead 9| which connects the lead 12 through the resistor 48 to the positive side of the source of power 66a. The

lead 9| is also connected at 9|a to the potentiometer 63. The neon tube 6| is connected to the binding post C by .a lead 93. The cathode of the amplifying tube 46 is connected by a lead 94 to the potentiometer 63. The lead 12 between the condenser 51 and the resistor 56 is connected to the resistor 49 by a lead 95; this latter resistor being grounded as shown at 91 to the casing of the instrument. The lead 82 is connected by a wire 96 to the lead 13, and in the wire 96 intermediately of its length the condenser 58 and resistor 53-are interposed. The binding post H is grounded to the casing of the instrument at 98. The operation is as follows: When the phototube 42 is exposed to increasing light its internal resistance decreases thereby causing the potential on the grid of the amplifying tube to become more positive, this increases the current in the plate of the tube 45 and through the leads 1| and 90 so that the grid of the tube 46 becomes less positive, resulting in a reduction in the current through the lead 12 and thereby making the side of the condenser 51 connected to the lead 12 more positive. The reaction of the condenser tube causing it to act' as a relay and energize 1 one of the ele'ctro-magnets 22 by allowing current to flow from the power supply 66throughthe leads 99, 88a, 80 and 19, the resistor 58 and the binding post F to the brush 39; and from the brush 3| through the leads 8|, and 82, post E, and the plate and cathode of the gaseous tube 41, leads 13 and 83, binding post G and back to the source of power 69. When this occurs one of 75 i the chucks 20 is held immovable byits magnet 22. The carriers l9 and I1 holding the chucks l3 and 20 are then ready to be rotated through 90' to bring the work to its printing position. As m rotation of the carrier l1 occursthe segments 24 and 25 energized through the brushes 30 and 3! also come into contact with the brushes 28 and 29 respectively. Then short circuiting of the brushes 29 and 3| by one of the segments 25 extingulshes the gaseous tube 41, thereby cutting off the supply of power through that tube, but as the brushes 28 and 29 are directly supplied with power from the source 69 so long as the switch 34 remains closed the 1 magnet 22 between these brushes remains energized until rotation of the carrier I1 has ceased, and a downward movement of the printing frame ll causes the switch 34 to open. Then of course the circuit is broken, and the chuck 20 in conjunction with which that magnet 22 operates is again free to turn.

When the switch 34 is opened there is an induced potential from the magnet 22 which would cause a destructive are were this magnet not then connected to the neon tube 6| through the brush 29, lines 15a and I5, binding post C and the lead as, and through the brush :8, lead is, binding post D, and lead I8. This tube limits the voltage to a low value and avoids the destructive are that would otherwise occur, and also eliminates disturbances to other partsof the electrical system which might. cause undesired "firing" of the gaseous tube 41 by which one of the magnets 22 which has just come ,into' contact with .the brushes 30 and 3| would be energized. Similarly the wide spacing of the adjacent segments 24, or

25, is necessary'for the same reason.

The operation is briefly as follows: After the I carriers l6 and II have been turned so that-the work A carried by an opposed pair of chucks I8 and 20 is Po itioned between the phototube 42 and the light source 43, the chuck 20 and the work are rotated by the disc 39 until the work reaches such a rotary position that light, from' the source, of increasing intensity reaches the phototube. Then a circuit is-completed through the brushes 30 and -3| and the electro-magnet 22 connected to the segments 24 and 25 with which the said brushes 3!! and 3| respectively are in contact. Rotation of the work is then immediately haltedby the brake plate '2: carried by the spindle 2| which is then drawn into intimate contact with the magnet. As the carrier 11 is turned to move the work to printing position upward movement of the printing frame ll closes a circuit through the brushes 28 and 29 and the same magnet 22. This short circuits the gaseous tube 4'! and breaks the circuit through the brushes 30 and 3|, however the same magnet remains energized'throughthe brushes .28 and 29 until the work has arrived at its printing position and the frame II is again lowered to its position for reciprocation immediately prior to its next printing stroke. By the lowering of the frame the switch 34' is opened and the circuit through the brushes 29 and 29 broken, so that the work about to be printed is again free to rotate in contact with the frame during the printing operation.
