HENRY A. WISE WOOD, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO DETROIT TRUST 00., TRUSTEE, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN PRINTING-MACHINE.

Application filed January 13, 1894, Serial No. 496,819.

To all whom it may concern:

Be it known that I, HENRY A. Wlsn W001), a citizen of the United States, residing at' New York, in the county of New York and State of New York, have invented a new and useful Improvement in Printing-Machines, of which the following is a specification.

The aim of this invention is to improve the 7 arrangement of parts and devices in traveldrawings, in which,

Figure 1 is aside elevation of a printing press arranged to work after my invention, Fig. 2 is a sectional elevation of the operating parts of the press, Fig. 3 is a diagram illustrating the movement of. the cylinder or cylinders, and Fig. 4 is a diagram illustrating the arrangement of the cam or cams that controls or control the feed of the web.

My invention relates to traveling cylinder web printing presses, or to traveling cylinder 1 Web perfecting presses, such as is shown and described in Letters-Patent granted toJohn H. Stonemetz, January 3, 1888, No. 376,053, or in Letters-Patent granted to Joseph L. Cox, July 5, 1892, No. 478,503. The op- "'1 eration of this form of press is Well understood, and in brief, is as follows :The printing couple consists of a bed upon which the form of type is placed, and of a traveling impression cylinder around which the web is led together with web manipulating devices,

which hold the web stationary while the impression is being made, or while the impression cylinder is in contact through the Web with the form, and which feeds or shifts the web forward for a new impression while the cylinder is thrown out of impression or is off of the form in either direction. The move ment of the impression cylinder, while the same is printing, may be called the printing movement, and the movement while the impression cylinder is not printing, and while the web is being fed may be called the reversing movement. In all presses of this class, heretofore designed and built, the reversing movement of the cylinder compared Specification of Letters Patent.

with the printing movement of the cylinder, so far as time is concerned is equal or is less.

In the Cox patent, before referred to, the time of the printing movement of the cylin der and the time of the reversing'movement of the cylinder, is the same, or, if the cylinder is driven forward and backward by a crank movement, the cylinder is in impression and out of impression for a quarter revolution of the crank.

I have found by practical experiments that the feed of the'web is the action that is determinative of the speed at which the press can be run, and that if a longer time is given to the feeding of the Web while the reversing of the cylinder is taking place, as compared with the printing movement of the cylinder, that the parts can be run at a much higher rate of speed than in the old arrangements.

Therefore, my invention consists of a traveling cylinder web printing press or web perfecting press in which the impression cylinder is reversing off the forms at either end thereof a longer time than the same is in contact with the forms, and printing. I have further found that an efficient arrangement is, if a crank is used to actuate the cylinder, to arrange the mechanisms so that the cylinder is in impression for one-sixth of a revolution of the crank, and out of impression, the web being fed, meanwhile during twosiXths of a revolution. With this arrangement, the web can be fed easier, as revolution for revolution, compared with the old devices, there is much more time to start, shift, and stop the web, and by this arrangement, I have found that I can greatly increase the speed at which the press can be run, as the printing can be done practically at any speed.

My invention further consists, in combination with a perfecting printing press of the character before referred to, of an off-set Web which is manipulated and fed by the same devices which manipulate and feed the web to be printed, and with guides, so arranged that the off-set web can be led through the machine so as to clear the first impression cylinder, and so as to prevent contact of the web-to-be-printed with the second impression cylinder.

I An apparatus embodying these improve ments, is illustrated in the drawings.

Referring to the drawings and in detail, A

represents the usual side frames of a press.

B and F represent. two stationary form beds which may be arranged in any conthese reciprocating carriers in the usual way are the impression cylinders D and E.

Arranged in the reciprocating carriers at each side of each impression cylinder, are form rollers G-G, to which ink may be supli'ed in any of the usual ways, not necessary liere to describe or show in detail, and these form rollers are so arranged that they will ink the forms on both the forward and backward movements of the impression cylinder, whereby an impression canbe made on both the forward and backward movement of the impression cylinders.

Forms 6 and f may be placed upon the stationary beds. The web to be printed may be fed to the machine from a web-roll W, and the path of the web to be printed, through the press, is as follows :-From the roll, the web is led between the continuously running feeding-in rollers 10. 11, and 12, then around the looping feeding-in roller 13, then around the stationary roll or guide 14.

' From this last guide, the web is carried to the guide 15 mounted in the carriers 0, under the first impression cylinder E, then around the guide or roll 16 also mounted in the. carriers 0 to the stationary guide or roll 17. a roll 18, which may be made adjustable in any of the usual ways, for the purpose of obtaining register between the two printing mechanisms. From this registering roll 18, the web passes to the guide or roll 19 carried by the carriers C, under the second impression cylinder D, around the carrier or guide 20 also carried by the carriers 0, to the stationary roll or guide 2]., then around the looping feeding-out roller 22, out between the continuously running delivery rollers 23, 24, and 25.

The looping rollers 13 and 22 are mounted in carriers 26, which are mounted in suitable guide-ways 27, formed in the main frames A, so that the looping rollers will be capable of vertical movement. Connected to the carriers or blocks 26 are arms 28 which have extensions 29, which are fitted into ways 30,

and these extensions 29 carry rollers 31, which engage the grooves 32 of track cams 33 mounted on shaft 34. Springs 340 may be arranged between the extensions 29 and a stationary part, if desired, to counter-bah ance the weight of the looping rollers and their appurtenances.

35 represents a shaft, which is journaled in bearings secured'to the main frames, and this shaft may be the driving shaft of the ma- From the roll 17, the web is led around with the second impression cylinder.

chine, if desired, and power may be supplied to the same, in any of the usual ways. Mounted on this shaft 35 are pinions 36-36, which mesh with and drive crank-wheels 3737 mounted on a shaft 38, which is journaled in the side-frames AA. These crank wheels 37 carry crank-pins 39, which connect by pitmen 40 to studs 41 on the carriers C, and by this means, the impression cylinders will be reciprocated forward and backward over the forms- Also meshing with one of the pinions 36 is an intermediate 42, which intermediate 42 mesheswith, and drives a gear 43 mounted on the end of the cam-shaft 34. The gear 43 is preferably made of one-half the size of the driving gears 37, and by this means, the cams 33 will turn twice for each forward and backward movement of the impression cylinders. The impression cylinders will be driven practically by a crank or cranks 380, of the radius at which the crank-pins 39 are set. Meshing with the intermediate 42 is a gear 44, which is mounted on a suitable stud,

and arranged to turn with the gear 44 is a I such, for example, as is shown in Fig. 1.

If it is desired to do nice printing, an off-' set web may be used to prevent contact of the first printed side of the web-to-be-printed This off-set web 'w may be led in from a roll W and may travel with the web to-be-printed as far as the roll 14. From the roll 14, the web E0 may be led under the first bed F, by meansof suitable guides or rolls 49 and 50, andmay unite with the web-tobe -printed on the roll 17, as shown in Fig. 2.

Instead of introducing the off-set web as above described it is evident that the offset web may be introduced between the surface of the first impression cylinderand the web to be printed, and may thereafter be trans ferred to the opposite side of the webtobe printed by any suitable arrangement of guide-bars. plate introducing the off-set web at the other end of the machine; that is to say, the ofi-s'et web may be led from its supply roll directly to the roller 17. From the roller 17, the web-'to-be-printed and the off-set web may travel together until the two webs are delivered from the continuously running delivery rolls, when the off-set web may be wound up into a roll W by any suitable winding device, as for instance, the cylinder 51, upon which the roll W may rest. This cylinder 51 may be driven continuously by any suitable means, as for instance, by means of pill- In some cases, I also contemleys 61, 63, and belt or cord 62, from any suitable part of the machine, as for instance, the last continuously running feeding-out roller 25. By this means, it will be seen that I can use an off-set web in a press of this character without complicating or increasing the mechanism, and simply by the addition of two guides or rollers, and by the addition of a rewinding device. Of course, so far as the first part of my invention is concerned, the off-set web need not be used therewith.

The relative arrangement between the feeding mechanism and the cylinder driving mechanism is peculiar, and may be comprehended from the diagram shown in the last sheet of the drawings. In Fig. 3 thereof, I have illustrated the crank movement which operates to move the impression cylinders, and as the pitmen which connect the cranks with the carriers, are so long the slight varia tion due to the use of the same may be neglected, and the cylinder may be considered as being driven directly by a crank as 380. In the arrangement which I have shown, I have given more time to the feeding or reversing movement of the impression cylinders than to the printing movement, and in the especial arrangement, I have made the reversing or feeding movement of the impression cylinders double the printing movement.

, Thus for one-sixth of a revolution of the cranks, the cylinders will be printing, for two sixths of a revolution, the cylinders will be reversing at one end of the form, for the next sixth of a revolution, the cylinders will be printing on the opposite movement, and for the next two-sixths, the cylinders will be reversing at the opposite end.

It will be seen by the plotting shown in Fig. 3 that the movement of the cylinders off the forms is not very large as compared with the movement of the cylinders while in impression, but it will be seen that the time of the movement of the cylinders while they are out of impression is greater or double the printing movement. This enables me to run the ress at a much higher s eed than has been before possible, because can, for instance, double the speed of the press, and still give the web the intermittent feed in the same time as in the presses where the printing movement and feeding movement are the same, and as the speed at which the printing is done, does not afiect the same, the increased speed will not affect the product. The cam or cams, to actuate the looping rollers, have necessarily to be proportioned to suit this arrangement, and in Fig. 4, I have shown in diagram, the peculiar form of cams used. Thus, in these cams, the same will be roportioned to move the loo ing rollers up or two-sixths of their .revo ution, and to draw the looping rollers down for four-sixths of a revolution of said cams, the downward movement giving the web its intermittent feed between the rollers or guides 14 and 21. Of course, so far as the broad scope of my invention is concerned, that is, of giving more time to the feed than to the printing, other devices can be used without departing from the scope of my invention, as expressed in the claims.

In Fig. 3, the reversing movement of the cylinders at the left, is represented by the distance between a and b; the printing movement in either direction, by the distance between I) and c, and the reversing movement at the right, by the distance between 0 and d.

In Fig. 4, the movement of the cam, which allows the web to remain stationary, is represented by that portion above the lines 6 and f, and the feeding portion of the cam is represented below the lines e and The function of the looping rollers in this class of machines is to 'hold the web stationary during the printing movement, or in other words, to absorb the web which is fed into the machine during the printing movement, and to give the same out during the reversing movement.

In a machine constructed according to my invention, the time of the printing movement is shorter than the time of the reversing movement, and it follows that the loopers are not required to hold the Web stationary during so long a period, and hence they may move more slowly, and cover shorter distances.

In a machine, in which the time of the printing movement of the cylinder is equal to the time of the reversing movement of the cylinder, the looping-rollers would have to take up twelve inches of web in order to print a twenty-four inch sheet, Whereas in a ma chine constructed according to my invention, and having the time of the printing movement of the cylinder equal to one-half of the time of the reversing movement of the cylinder, the looping-rollers would only have to take up eight inches of web in order to print,

the same length of sheet, which results in a considerable saving in power, and in wear of the parts. So far as this part of my invention is concerned, the same may be applied to a traveling cylinder printing press, in which a single cylinder is used, or in which a plurality of impression cylinders are used.

The details and the mechanisms for accomlishing the functions herein described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.
