Specication of Letters Patent.

Application filed July 26, 1910. Serial No. 573,884. j U

To all whom it may concern:

Be it known that I, WILLIAM JACKSON, a citizen of the United States, and a resident of the cit of New York, borough of Brooklyn, in t e county of Kings and State of vNew York, have invented new and useful Im rovements in Printin -Machines, of which the following is a fu 1, clear, and exact description.

The invention relates to wal] paper p-rinting machines, and its object is to provide 'certain new and useful improvements in rinting machinesfor printing wall paper orders, whereby the paper after it receives the imprint by the printing rolls is accurately cut lengthwise along the contour ofthe imprint. For the purpose mentioned, use is made of a cuttin roll rotating in unison with the printing rol s and having a peripheral cuttlng edge corresponding to the contour of the imprint produced on the paper by the printing rolls.

' impression c linder B in the A practical embodiment of the invention ris represented in the accompanying drewings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a perspective view of part of the wall paper printing machine provided with the device for cutting the paper lengthwise along the contour of the imprint; and Fig. 2 is a sectional side elevation of the same.

The printing machineis mounted on a suitably constructed frame A, in which is mounted to rotate the impression cylinder B andV the rinting rolls C for producing the imprint B on the paper E passing around the p sual manner. The shaft'C of each of the prlnting rolls C is provided at one end with a pinion C2, in mesh with a gear wheel F rotating in unison with the lmpression cylinder B, sothnt the printing rdlls G rotate in unison with each other, and each printin roll C is suplied as with ink by a suitable inking device indicated in Fi printing rolls (Jg The printing machine so far descri ed is Patented J une 6, 1911.

of well known tye, and it is not deemed]` necessary to furt er describe the detailmechanism thereof.

.On the delivery side of the (printingmw 'chine are arranged rolls-H van I, of which the roll I is acutting roll and the roll H any impression roll, and between the said rolls passesthe paper E after it has received the imprint D of' the printing rolls C. The` 60 ings J held ad'ustably on the frame A, s0 i shaft I of the roll I is journaled. in4 bearas to permit o moving the roll I closer to or farther from the roll H, which lutter. is `v journaled in the frame A. The shaft I of the roll I is connected by a gearing K withv the gear wheel F, so as to'rotate the roll I in unison with the printing rolls C. On the peripheral face of the roll I is arranged a continuous cutting edge I2, conforming in shape to the contour D formed on the imprint D by the printing rolls C, and as the cutting roll I rotates in unison with the printing rolls C, it is ,evident thatwhen the machine is running the cutting edge I cuts the paper E lengthwise along thecontour D of the imprint D. The paper E, after it is cut lengthwise as described,` passes over a roll L, and then the portion having the.im.
