SPECIFICATION Vfarming part of Letters Patent No. 382,684,v dared May 1s, 188s. Application tiled April 19, 1887. Renewed February 27, 1888. Serial No.'265,432. (No model.)
To all whom it may concern:
Be it known that I, THOMAS S. BowMaN, of St. Louis, Missouri, have made a new and useful Improvement in Printing-Machines, of
which the following is a full, clear, and exact description.
The improvement relates to means for readi ily changing the intervals between the print ing of the impressions. It is applicable to several styles of printing-presses; and it is illustrated in connection with a mechanism for printing impressions upon a continuous web ofpaper,subs`tantially as shown in the annexed drawings, making part of this specification, in which- Figure l is a plan of the improved press. Fig. 2 is a vertical longitudinal section on the line I l of Fig. 1, and Fig. 3 is a plan, upon an enlarged scale, of the form-bearing belt. f
The same letters of reference denote the same parts. .l
Only those parts of the press deemed essentalto an understanding of the improvement are included in the drawings.
A, Figs. l, 2, representsa roll of paper upon a shaft, a., journaled in the uprights B B. The web a is fed past the cylinder C, and is wound, say, into a roll, D. The form used in making the impressions is shown at E. It is attached to a belt,.F, which is carried around the rollers G and H. The parts are adjusted to cause the form E, as the belt moves around the rollers G H, to make an impression upon the web a as the web and form move past each other. The form E is flexible-such as a rubber type-to enable-it to bend as it is carried around the rollers, and to conform to the belt in its course. Motion is communicated to the movable parts of the machine by means of the pulley I upon the shaft J, which also carries the cylinder C and' gear K. The'gear en gages with the pinion L upon the shaft of the roller H, which is thereby d riven and the belt moved, as described. The shaft J is also furnished with a pulley, M, and the shaft d of the roll D is provided with a' pulley, d', and 4by means of a belt, N, motion is communicated to the roll D, and that roll thereby wound up. The pulley d is made smaller than the pulley M. The roller H may be provided with bands h, to cause the web a to be fed properly past the roller H. The distinguishing feature, however, of the improvement is the form-car rying belt F. This belt is carried around at least two rollers, G H, and is made to be lengthened or shortened, in order thereby to Y cause the form E tobe presented at longer or shorter intervals to the web a', and thus prov vduce the impressions farther from or nearer to each other upon theweb.
In Fig-3 is shown a desirable inode of alteri ing they length of the belt-namely, by theinsertion of the section f, snbstantiall y as shown. As the length of the belt is changed, the rollers G H, must be correspondingly relatively placed. It is better for the roller H to remain in one position and to changethe'support ot' the other end of the belt.
Gare made adjustable toward and from the roller H, the bearings in the present instance being in a cross-bar, O, which can be moved upon the frame P of the machine toward and from the roller H; but other means can be einployed for supporting the outer portion ofthe belt without necessarily altering the position of the roller G.V For instance, a third roller, ofthe nature of an idler-pulley,l may be used to take up the slack ot' the belt when it is lengthened. I
The improvement is especiallyadapted to the printing of impressions upon webs of Wrap-v pingpaper. It is customary for merchants to To this end, and as f a desirable means, the bearings g of the rollerV utilize sheets of wrappingfpaper as a means of f advertising.
I propose wmith thepresent machine to print sheets, however, must be of various sizes, andv the impressions must, accordingly, be printed closer together or farther apart upon the web. This can be accomplished with a formcarry ing belt capable of being lengthened and short` ened, substantially as described, and with each change in the spacing of the impressions a new roll of-paper can be used.
I claimmi 1. The extensible form carrying belt, in B B', the cylinder C, the extensible form-bearcombination with the impression-cylinder, as ing belt, the roller H, and the adjustable roller and for the purpose described.
2. The combination of the extensible form- G, substantially as described.
5. The combination of the cylinder C, hav- 5 carrying'belt, the roller H, and the cylinder` ing the continuous surface c, with the rollers C, substantially as described.
3. The combination of the adjustable roller G, the extensible fornrcarrying belt, the roller H, and tbe cylinder` C, substantially as de- Io scribed.
4. The combination ofthe shaft a, nprglits G H, and the extensible form-carrying belt, substantially as described.
