EDWYN ANTHONY, OF NEW YORK, N. Y.

PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 275,113, dated April 3, 1883.

Application filed November 15, 1882.

To all whom it may concern Be it known that I, EDWYN ANTHONY, a subject of the Queen of Great Britain, residing at New York, in the county and State of New York, haveinven ted anew and useful Improvement in Printing-Machines, of which the following is a specification.

My invention consists in a mechanism for printing simultaneously on both sides of two webs and causing them to issue, so that the method of associating webs together described in Letters Patent No. 263,748 (granted to myself and Jacob E. Harvey, and dated September 5, 1882) may be applied.

Figure 1 illustrates one arrangement of mechanism for accomplishing the above purpose; Fig.1,a modification of the said arrangement. Fig. 3 is a bottom view of Fig. 1. Fig. 2 shows how the mechanism of Fig. 1 may be used when only half the number of forms shown in Fig. l are placed on the machine. Fig. 4 is a plan view of the reversing device shown in Fig. 1. Figs. 5 and 6 are plan and side views,respectively, of a similar device, but one which deflects the path of the web without reversing its sides; and Figs. 7 and 8, similar views of another mechanism for reversing a web. I

D U are the form-bearing cylinders, their axes being parallel to one another. Round each are placed an appropriate number of impression-cylinders. When the forms (the maximum number being on the machine) occupy the whole circumference of the cylinder, then' two impression-cylinders will be required in connection with each form-bearing cylinder, asin Fig. 1. When only half the circumference is so occupied. then four impression-cylinders will be needed, as in Fig. 1; when only a third, six impression-cylinders, and so on, and corresponding numbers of carrier-cylinders must be used to conduct the webs from one impression-cylinder to the next. Thus when the impression-cylinders are four in number for each form-bearing cylinder there must be two carrier-cylinders for each; when six, four, and so on.

Fig. 1 illustrates the case of the maximum number of forms occupying one-half the circumference of the cylinder. There are four impression-cylinders, L K M N, in connection with D, and four, E F G H, in connection with No model.)

0, two carrier-cylinders, T V, in connection with the four first-named impression-cylinders, and two, R S, in connection with the four last named.

P Q are cutting-cylinders, and they may be placed in any convenient position.

Details of inking, cutting, &c., are not given, because this invention does not relate thereto,

and those operations may be effected in any usual and suitable Way.

Whatever portion of the circumference is occupied by the forms, the course of the webs may be described as follows: The web B is suitably conducted and completely printed on one side by the form-bearing-cylinder D. It is then led to and is completely printed on the other side by the form-bearing cylinder 0. Next it passes through a deflecting apparatus, such as Fig.4,Fig.7,orFig.5, (according to the object in View, as hereinafter explained,) and finallygoestothecutting-cylinders. The webA is first completely printed on the other side by the cylinder D, the web being able to cross the path of the web B through the open space caused by the deflecting device. Referring now more particularly to Fig. l, the web passes between D and L, round T, and thence between-D and K, thus getting printed on one side. It next passes between H and 0, round S, and thence between C and G, thus receiving an impression on its other side, after which it passes through the reverser (Fig. 4 being a plan view thereof) and goes on to the cuttingcylinders P Q. The web A passes between 0 and F, round R, and thence betweeen 0 and E. Now printed on one side, it is led round suitably-placed rollers X Y Z, and passes between the space 9 Zd (see Fig. 4) to the cylinder M, thence round V to between D and N, whence it issues completely printed on both sides, and goes to the cutting-cylinders P Q. The webs are now both printed on and issuing so as to satisfy the conditions necessary for associating any number of webs with them in the manner explained in the aforesaid Patent No. 263,748, when it is desired to print only papers the number of whose pages are even multiples of two. The added rolls must be printed on and issue as therein explained, and

When it is required to be also able .to print papers the numbers of whose pages are, odd multiples of two, then the mechanism shown in Figs. 5 and 6 must be substituted in Fig. l in place of the reverse therein shown. The course of the web A will be as before,.and also that of the web B, except that it will pass through Fig. 5 instead of through Fig. 4, and will therefore have its pages the reverse way up to what they were in the previous case. The two webs will thus, in this case, be printed on and issue in the manner described in line 42 to 53, page 1 of the aforesaid specification, No. 263,748; and the association of other webs with them may be effected, as therein described.

In the plan view, Fig. 3, the cylindersare shown of diii'erent lengths for the sake of clearness. Fig. 2 illustrates the machine shown in Fig. l as used to print a smaller number of pages. 011 the cylinders G and D only half the previous number of forms are placed, so that they occupy but one-fourth of the circumference. The roll A is not used. The roll B follows the same path which it does in Fig. 1 until it has passed between G and G. Thereupon, instead of beingled to the deflecting mechanism, itpasses round the roller W, thence between G and F, and afterward follows to the cutting-cylinders the same path which the web A does in Fig. 1. It is clear that the web will issue from the cylinder N completely printed on both sides. The cylinder Wis not shown in Fig. 1, because, unless it be required to use the machine in the way shown by Fig. 2, such a cylinder is unnecessary.

As before remarked, my invention is applicable whatever multiple the whole circumference of the cylinder D or 0 may be of the are occupied by the forms, nor obviously need each cylinder be the same multiple thereof. Thus the forms might go all around D and one-third round O,orvice versa, 850. It is unnecessary to illustrate various cases by diagrams, as these considerations do not afi'cct the principle of our invention. I give, however,one figure, Fig. 1, to illustrate the case of the forms occupying the whole surface of both cylinders. This figure also illustrates the use of the device Fig. 5, which deflects without reversing the web. The way of printing from half the number of pages will be similar to that in Fig. that is to say, the forms will occupy one-half of the circumference of Dand O,and the webA is not used. The web 13 follows the same path that it does in Fig. 1 until after it has passed between G and G. From thereit-must be taken by suitably-placed rollers, so as to pass between 0 and E, and afterward it follows the same course which the web A does in Fig. 1. Thus it will issue at N completely printed on both sides.

I will now more particularly describe the deflecting mechanism.

a k c andfe (I, Fig. 4, are triangular-shaped frames, made of any suitable material. They are equal in all respects. The angles at and e are right angles, and those at c and fare equal to any convenient angle less than fortyfive degrees. Taking, for cxample,each of the angles at c andfto be one of thirty degrees, then first the planes of the triangles must be inclined to one another at an angle of one hundred and nine degrees and twenty-eight minutes, approximately; secondly, the edges a it and e 61 must be placed so as to be parallel to one another, with any convenient distance between them, and so that the plane drawn through 70 e perpendicular to the plane of the web before it enters the apparatus may pass through the point 07; third, the rollers l and 9 must be fixed so that Z touches the edge df produced of the trianglefe d, and g the edge a 0 produced of the triangle a 70 c.

The axis ofg must be inclined at an angle of fifty-four degrees and forty-four minutes approximately to 70 c, at an angle of sixty degrees to (t e, and the axis ofl must be parallel to that of g. The rollers l and g should be placed at a sufficient distance apart to admit of other webs, &c., passing freely through one or other of the open spaces a g l and d lg.

The edges to c andfd should be somewhat rounded, so as not to have a tendency to tear the web while passing over them. The web should be passed over the triangle a k a, so that its central line passes over the middle point p of the side a c.

The course of the webin its passage through the apparatus is easily traced. It passes over the edge d f, then round Z, from thereroundg, and finally over the edge a o, issuing with its edges lying in the same pair of parallel planes that they did before the web entered the apparatus, but reversed, so that the upper surface of the web, before entering theapparatus, becomes the under surface on leaving the apparatus.

The mechanism, Figs. 5 and 6, consists of the same parts as does Fig. 4; but they are difi'erently arranged. Here the planes of the triangles a c 70 cl 0 f are parallel to one another. So are also their edges a c d f. The axes of the rollers g l are parallel to one another, and are inclined to the edges a c df at an angle equal to the complement of the angle 0 orf. The roller 9 touches the edge a 0 produced and the roller l the edge df produced, and the plane through k c perpendicular to the plane of thetriangle a 0 k must pass through the point (1. The central line of the web must pass over the middle point of the edge (1 f. The distance between the planes of the triangles depends upon the breadth of the widest web that it is desired to pass through the apparatus.

The course of the web in its passage through the apparatus may be easily traced. It will be observed that the web is deflected from its path and brought back again without the reversal of its sides, the deflection providing the open spaces a 0 l d f g, through either of which other webs, &c., may be passed. Fig. 7 is a plan view, and Fig. 8 another view, of an apparatus which, like Fig. 4, reverses the sides IIO IIS'

of the web; but the planes of the web on entering and leaving the apparatus are parallel to one another, as in Fig. 5, instead of being inclined to one another. Thisfactoften makes it more convenientthan the mechanism ofFigA.

The triangles a c" k" d 0"f are equal in all respects. The angles at k and e are right angles, and the angles at c andf any equal angles less than forty-five degrees. Thirty degrees is perhaps the most convenient size for these last-mentioned angles. The triangles are placed with their planes parallel, and so that the plane through 70 a perpendicular to the planes of the triangles passes through f e. The distance between the planes of the triangles depends on the breadth of the widest web which it is intended to pass through the apparatus. The roller g must touch the edge a 0 produced of the triangle a e k, and also the edge f" produced of the triangle 11 e"f. Its axis must be inclined to the edge a 0 and alsoto the edge df at an angle equal to the complement of the angle 0 orf. An inspection of Figs. 7 and 8 plainly are printed.

webs, now in sheets, must he conducted between tapes, and the circumferences of the form-bearing cylinders must be multiples of the arc occupied by the forms plus the interval between successive sheets at the time they are printed on.

The deflecting mechanism shown in Figs. 4, 5, and 6 I donot claim.

What I do claim herein as myinvention is- 1. The combination and arrangement of thetwo forth-bearin g cylinders (whose axes are parallel to one another) andimpression and carrier cylinders with the mechanism for deflecting (after it has been printed on both sides)the path of one of the webs, whereby two distinct webs are simultaneously printed on both sides, and are caused to issue as hereinbetore set forth, all substantially as described.

2. The combination of two triangularf'rames, fixed parallel to each other, with a roller whose axis is inclined at an angle to the planes of the triangular frames, whereby the sides of a traveling web or of sheets in tapes are reversed, all substantially as described.
