EUGENE E. LA ROSE, OF HACKENSACK, "NEW JERSEY.

ROTARY-REGISTRATION MACHINE.

To (LU/1.0720777, it may concern:

Be it known that I, EUGENE E. LA Rose, a I

larly with that step in the manufacture of decorative printed matter where it is desirable to perform a second operation thereon, such' as cutting out wall paper borders or printing one or more additional prints in a separate machine, and relates especially to the second operation in which it is essential to register with the pattern of the first or some preceding operation.

To those familiar with the art to which this invention appertains, it is well known that it is very di'iiicult to secure a perfect registration upon or during the second operation and that a machine which will successfully accomplish this result in a perfect manner is a desideratum. For example,

while the printing rolls and the cylinder or rev-oluble bed in rotary printing machines are supposed to have an equal circumference speed, yet in practice that is very seldom found to be the case and the pattern is printed short or long according to whether the cylinder or the print rolls are traveling the faster. Furthermore, it is also well known that the materials that are being printed on will vary more or less in length after they have been operated on, and manifestly this will change the length of the printed pattern. Besides, there are a number of other causes that will change the length of the printed pattern from the true length of the pattern rolls, this being so when the second operation is required to obtain'a desired result; hence a flexible method to obtain registration in the second operation must be employed and obviously the more direct, sensitive and controllable the mechanism is, the more perfect will be the registration obtained.

Specification of Letters Patent.

Patented @et. 31, 1916.

Application filed August 12, 1914. Serial No. 856,510.

In all of the machines made or inethods heretofore employed or proposed within my knowledge, reversing gear mechanism is employed to obtain the desired result and consequently there is a back-lash set up in the gears, and one of the primary objects of my invention is a simple, durable, eflicient, sensi tive and very easily controllable flexible mechanism for this purpose in which the transmission is in one direction only and does not change to vary the speed of the operating rolls to obtain the desired registration so that no back-lash is possible, it being one of the main objects of my invention to avoid the use of any gear or moving part of the transmission that is released or reversed to obtain the required adjustment of the operating roll and when the machine is started, all looseness of the parts such as clearance between the gear teeth or any other parts, is taken out and, as there is no reversing or releasing of my transmission mechanism, there is no looseness of the parts to interfere with obtaining the required perfect registration.

In other words, one of the primary objects of the present invention is a machine of this character in which the fleXible transmission is operative to change the speed of the operating rolls without releasing any member of the transmission, whereby all loose motion and intermittent control is done away with.

A further object of the invention is a registration machine in which there are eifective means for obtaining manual control of the circular registration where a positive or constant adjustment is made to compensate for any variations between the length of the printed pattern and operating roll; and in addition thereto, an emergency adjustment that can be operated to cause a quick and greater range of speed between the operating roll or rolls and the printed matter contained on the cylinder as, for example, when there is a tear or other defect in the web or sheet, such emergency adjustment, or rather the mechanism providing therefor, when released, providing that all of the parts will return to the position of the positive or constant control to which the mechanism has been initially set or adjusted.

Another object in this connection is. to provide means whereby the speed of the web 0 linder and web treatin rolls ma be controlled, and means whereby the speed of the web treating rolls may be controlled independently of the first referred to controlling means. In other words, whereby the web cylinder and treating rolls may be brought to a very slow speed, if desired, and then the speed of the web treating rolls increased or diminished relative to the speed of the cylinder without necessitating the stoppage of the web cylinder and the consequent stoppage of the paper.

The invention has for a still further object improved means for obtaining a lateral control or adjustment of the operating rolls in multiple from one point of control, located so that the operator will not have to shift from the position of the other controls, but at his place at the front of the machine, can operate all of the different parts, not only as regards the circumferential or rotary adjustment but the transverse or lateral ad-- justment, without shifting his position or without losing control of any of the parts. And the invention also aims to generally improve machines of this character so as to render them more useful and commercially desirable.

With these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain details of construction, arrangement and combination of the parts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which,

Figure 1 is a side elevation of a machine embodying the principles and improvements of my invention. Fig. 2 is a top plan view thereof, parts being broken away. F ig. 3 is a view in the nature of a diagram showing the web as it is passed around the cylinder and the operating rolls acting in conjunction therewith. Fig. 4; is a detail plan view,

partly in section, of the means for manually adjusting the transmission to secure the ro-' tary or circumferential registration. Fig. 5 is a side elevation thereof, the parts in sec tion and partly broken away. Fig.6 is a detail sectional view on the line 6 6 of Fig. 5. Fig.7 is a side elevation of a part of the means for obtaining transverse or lateral registration by the late al. adjustment of the operating rolls. Fig. 8 is a detail view of the main clutch for starting and stopping the machine, and Fig. 9 (Sheet 2) is a detail view of one of the operating rolls. 2

Corresponding and like parts are referred to in the following description and designated in all of the views of the accompanying drawing by like reference characters.

Referring to the drawings, the numeral 1 designates a web with a design printed thereon from a prior operation, the web of paper passing over the pulling out roll 2 with which it is held in contact by the roll 3. The web 1 passes into my improved registering machine between the guide flanges 4 and thence passes through or around the tension rolls 5. It then passes around the revoluble bed or cylinder 6 (Fig. 2) with which it is held in contact by means of a dummy roll 7 mounted inadjustable bearings (not shown). As it passes around the cylinder 6, it meets successively any desired number of operat ing or web treating rolls, there being two of these in the present embodiment of the invention, designated 8 and 9, respectively, although it is to be understood that the in vention is not limited in this regard. It is also to be understood that the operating or web treating rolls may be either print rolls or cutting rolls. For example, as indicated at the outset of the specification, after the web of paper has been operated upon and printed with the desired decorative design, it is passed into my improved machine for a second operation which may be a printing operation or the like, or a cutting operation as for instance the cutting of the border of a wall paper design. Hence the term web treating rolls as applied to the rolls 8 and 9 which are driven by the flexible transmission of my invention is to be considered as a comprehensive one and not limited in any sense to an operating roll of any particular character. I

As the web passes the last operating or treating roll in the series, it extends up over the conveyor roll 10 and thence to the endless apron or conveyor 11 from whence it is discharged, as desired.

The cylinder 6 is driven at a predetermined constant speed by means of a pulley 12 which is mounted loose on the transversely extending drive shaft 13 and is operatively connected thereto by a clutch mechanism hereinafter described, said drive shaft hav a pinion Pl keyed or otherwise fixed thereto, said pinion meshing with a gear w ieel 15 on the shaft 16 of the cylinder. said gear wheel having a pitch equal to the diameter of the cylinder, as best illustrated in Secured to one end of the drive shaft 13 is a bevel pinion 17 which meshes with a bevel pinion 18 splined on a longitudinally extending and horizontally disposed countershaft 19 which is movable longitudinally in its bearings and which has keyed thereon to move longitudinally therewith a friction drive pinion 20. The pinion 20 has its periphery in driving contact with the face of a friction disk 21 which is mounted on a stub shaft at one end of the frame work, said friction disk being in a sense, the master wheel of the flexible transmission which constitutes my invention and being provided on its edge or periphery with gear teeth 22.

These teeth mesh with pinions 23 and 24 that are carried by the shafts 25 of the web treating rolls 8 and 9 hereinbefore referred to, and thusit will be' understood that the speed at which the disk 21 is operated will control the speed of revolution of said web treating rolls, it being understood that the pitch of the toothed disk 21 corresponds to the pitch of the driving gear 15 and cylinder 6 and that the pitch of the spur pinions 23 and 24: is equal to the diameter of the web treating rolls. The ratio of the diameters of the friction pinion 20 and friction disk 21 is such that when adjusted at a neutral point indicated by the line 26, the speed of the friction gear disk at the pitch line of the gear will be equal to the surface speed of the cylinder 6. In order to vary the surface speed of the web operating rolls 8 and 9, the countershaft 19 is movable longitudinally in its bearings as hereinbefore stated and improved means are provided not only for moving this countershaft to a predetermined point so as to obtain the constant ratio, but means are also provided whereby a quick shift of said shaft may be effected, after which the shaft will automatically be returned to its set or constant speed, as required. These means will now be described.

A shipper lever 27 is fulcrumed intermediate of its ends as at 28 on a bracket 29 carried by the main frame work of the machine, said lever being provided at one end with a yoke 30 which is operatively connected by pin and slot to the countershaft 19, and the other end or arm of said lever passes inwardly in a lateral direction and is mounted between two longitudinally disposed plungers 31, as best illustrated in Figs. 4: and 5. The plungers 31 are encircled by coil springs 32 and are mounted in a car- -riage 33 which is slidably mounted in a guide way formed in a bracket 34 carried by the frame work. Movement is imparted to the carriage 33 by means of a threaded actuating rod 35 which is provided at one end with a hand wheel 36 and hence, it will be understood that as this actuating rod is turned inone direction or the other, the entire carriage will be moved rearwardly or forwardly, as the case may be, and the shipper lever 27 will be correspondingly moved, whereby the countershaft 19 is moved longitudinally in its bearings and the position of the friction pinion 20 is shifted toward or away from the center of the friction disk 21, whereby to increase or decrease the speed of rotation of said disk and as a consequence, the speed of rotation of the web treating rolls 8 and 9. Manifestly, bythe provision of the spring held plungers 31 betweenwhich the inner or handle arm of the lever 27 is mounted, a quick movement may be imparted otherwise injured at any .point and then when the speed of the web treating rolls 8 and 9 has thus been excessively varied so to speak, just as soon as the operator releases his hold upon the lei er 27, it will be returned to its normal or set position and the constant or set speed will be automatically resumed.

For the convenience of the operator, a vertically adjustable seat 37 is provided at the front of the machine, said seat being carried by a pedestal or standard 38 whereby the inner or handle end of the lever 27 will always be in convenient reach of theright hand of the operator or attendant. Immediately to the left of the standard 38 a clutch operating foot treadle 39 is disposed, the same extending rearwardly and being fulcrumed at its rear end and being connected at one end to a bell crank lever ell, one arm of which, as at 412, is adapted to engage a clutch collar 43 on the drive shaft 13 so as to press said collar into frictional engagement against the hub of the drive pulley 12 and operatively connect the latter to the shaft.

Mounted on the shaft 13, at the inner side of the drive pulley 12, is a pulley 41 1 around which a drive belt 45 passes, said belt being designed to drive the pulling out roll 2 and mounted within the frame work on the drive shaft 13 at the right hand side of the frame work is a pulley 46 around which a drive belt 47 passes, said belt also passing around a pulley 48 on the shaft of the conveyer roll 10.

From as much of the specification as has preceded in connection with the correlated views of the accompanying drawings, it will be understood that the operator sitting in front of the machine on the stool 37 will watch the web as it passes through the machine around the cylinder 6 and between the same and the web treating rolls 8 and 9 and if any advancement or retardation of said rolls is required, he will merely turn the hand wheel 36 in the required direction to move the 'countershaft 19 and the friction pinion 2O rearwardly or forwardly until the proper constant ratio of speed has been secured. Should the paper be torn at any point, for example, or defective in any way, so that a quick shift in the flexible transmis sion becomes necessary, it is only necessary for the operator to grasp the inner or han dle end of the lever 27 and move the lever forwardly or rearwardly as required until the defective portion of the web shall have passed, whereupon it is only necessary for him to release the lever and it will be automatically brought back by the spring held plunger 31 to its initial set position.

As stated at the outset of the specification, it is not only necessary and desirable to provide for circumferential or rotary registration, but for lateral registration also and the means I have provided for that purpose, I

' shall now describe.

Extending laterally from the main frame Work of the machine and secured thereto in any desired way, is a threaded stub shaft as on which a casting 50 (see Figs. 2-and 7) is mounted, said casting embodying divergent arms 51 which carry segmental bars 52. Each of the shafts 25 of the web treating rolls 8 and 9 is provided at one end with an adjustably mounted grooved thimble 53 and the segmental bars 52 have their edges received in the grooves of said thimbles, respectively. The casting 50, which as an entirety, together with its concomitant elements, constitutes a lateral shifting device for the web treating rolls in multiples or simultaneously, is provided with an extension arm 54 on the end of which is secured or formed a toothed segment 55 which meshes with a laterally widened pinion 56 on a transversely disposed actuating rod 57 journaled in a bearing 58 and provided at its inner end, convenient to the 'operators stool 37, with a hand wheel 59. Obviously, by rotating the actuating rod 57, the casting 50 will be turned on the threaded shaft 49 and, owing to the threaded engagement of the casting with the shaft, the former will be moved in or out, as required and the web treating rolls 6 will be correspondingly moved. Hence a perfect registration, laterversely considered, can be operated without 1 the operatoror attendant leaving his seat, and that the operator has control at this point over the speed at which the machine will operate and that in case of a bad place in the paper, he can quickly adjust the machine so as to produce a speed such as may be required until the proper adjustments to obtain theregistration have been obtained.

7 It will also be seen that in my machine, all

motion is transmitted to the flexible friction driving mechanism in one direction and that operating the machine to obtain the registration will not cause any reversing or releasing of any, gear and neither will there be any lost motion set up in the transmission mechanism. It is furthermore pointed out that with my invention the control of the speed of the web feeding cylinder 6 is to a certain extent independent of the control of the speed of the web treating rolls. Thus with the web treating rolls running at any desired speed the'speed of the web feeding cylinder 6 may be controlled by operating the clutch l3 and the speed of the cylinder 6 may be thus brought from maximum to a complete standstill, or vice versa, as thenecessities of any particular case demand. Thus, for instance, the web having become in a condition such that a large range of adjustment is required to get the web treating rolls into'proper registration with the printed matter upon the web, the speed of" the feeding cylinder may be slowed down until the adjustment of the web treating rolls is made. If the feed of the web were continuously at a high rate of speed there would be more or less paper passed around the cylinder while this adjustment of the paper treating rolls was being made and the paper just passed around the rolls would be wasted, as it would be out of regis tration with the web treating rolls. If the feeding cylinder 6 were stopped inorder to make the required adjustment while the web treating rolls continue to rotate, then the treating rolls would have to'be taken out of contact with the web. Unless they were out of contact they would have a tendency to tear the web, as the slippage of the rolls would come all at one point of the web, and further, in case of using the rolls for cutting, the adjustment, with the paper being fed at a relatively high speed, that is, at its normal rate, could only be very slight with out putting the web in such a condition that it would not pass around the cylinder in an operative condition. If, however, the web can be slowly fed forward while the registering adjustments are being made, there will be no great strain on the web at any one point as it is moving while in contact with the cutting rolls, and a maximum range of adjustment can be made without putting the web out of running condition, and a m nimum amount of the web passed through the machine while making these adjustments.

"The ability ,to control the speed of the web and independently control the registration of the web treating rolls is very important in this class of machine, as it is possible to operate with a very small margin of waste, while in those machines where the web is constantly driven at a normal rate of speed without any provision for regulating the speed of the web and independently regulate the registration controlling means, the amount of web that is spoiled while registration is being secured is very great in proportion, especially if the web is in a poor or broken condition. A further important advantage derived from the construction above statedis that if the machine has to be stopped, that is, if theweb has to be stopped in order to make the registration adjustments, and if the web operating rolls have as a consequence to be moved from contact with the web upon the cylinder, more or less trouble will be caused and there will be more or less waste,'as the adjusting of the roll to obtain a proper contact with the web is a matter requiring great care and more or less trials being made to prove it correct. This proving up U causes a waste of material, and the more trials that are necessary the more waste there is.

It is to be noted by reference to Fig. 2 that in my mechanism the speed of the transmission shaft 13 is controlled by means of the clutch t3, and that when this clutch is completely thrown out the transmission shaft will be entirely disconnected from the power and will stop, and that various speeds may be secured for this shaft by properly operating the clutch A slowing down of the speed of the shaft 13 would of course also slow down correspondingly the speed of the counter-shaft l9 and consequently reduce the speed of the friction disk 21 and the web treating rolls, but it will be obvious that the speed of the web treating rolls may be increased with reference to the speed of the counter-shaft 19 or shaft 13 on the cylinder G by shifting the friction wheel 20 farther toward the center of motion of the disk 21, or that the speed of the web treating rolls may be decreased below that of the cylinder 6 by'shifting the wheel 20 toward the periphery of the disk 21. Thus the speed of the web and the speed of the web treating rolls may beindependently controlled within certain limits. It will of course be obvious however that it would not be possible nor desirable when the web is running very slow to run the web treating rolls at a very high rate of speed.

While the accompanying drawings illustrate what I believe to be the preferred embodiment of my invention, it is to be understood that the invention is not limited thereto, but that various changes may be made in the construction, arrangement and proportions of the parts without departing from the scope of the invention as defined in the appended claims.
