MACHINE FOR FACILITATING THE TRIMMING OF WALL-PAPER.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed April 19, 1913. Serial No. 762,281.

To all whom it may concern:

Be it known that I, CHARLES GREEN, Jr., engineer, a subject of the King of Great Britain, residing at 21 Northdown street, Kings Cross, London, England, have invented certain new and useful Improvements in Machines for Facilitating the Trimming of Wall-Paper, and of which the following is a specification.

This invention refers to apparatus for attachment to a machine for printing wallpapers, through which apparatus the paper before it has been printed is caused to travel, and by passing between grooving rollers set at the required distance apart, grooves are impressed on opposite sides of the paper at a distance apart corresponding with the pattern to be printed onthe paper and so as to leave the unprinted edges of the paper that is, the list or trimmings, outside the said grooves.

Now in machine-printed wall-papers the pattern is, not always printed in an exactly central position on-the roll of paper, the result being that the unprinted edge or list varies in width, sometimes being wider on one side of the printed pattern than on the other, and therefore to fulfil the requirement of grooving the paper always at the edges of the pattern about to be printed, means are provided, according to this invention, for the simultaneous lateral adjustment of .the set of grooving rollers or disks relatively to the wall-paper while the machine is running, and the said grooving rollers are so laterally adjusted by a hand controlled mechanism; thus the grooving rollers are always made to correspond with the edges ofthe pattern being printed. Moreover it is also desirable that convenient means should be provided by which the operator can at any time desired throw the grooving rollers into and out of operation.

' The object therefore of the present invention is to provide an improved construction of apparatus or machine, and by which the before mentioned requirements are efiiciently carried out, and the said invention will now be described with reference to the accompanying drawings.

Figure 1 shows in two portions a sectional front elevation of the apparatus applied to the frame of a wall-paper printing machine, and Fig. 2 is a sectional end view of the said apparatus, Fig. 3 being a detail in plamhereafter referred to,

A portion of a frame 1 of a wall-paper printing machine is shown at Fig. 1, to which two brackets 2, 3 are attached. One of these brackets 2 is formed with guides 4 on which an adjustable standard 5 is carried, while a similar standard 5 is fixed to or formed with the bracket 3. The adjustment of the said standard 5 to the right or left is effected by means of a screw-threaded shaft 6, carried in the standard 5 and engaging with its screw thread in a correspondingly screw-threaded bearing or nut in the standard 5; the lateral adjustment shaft 6 is fitted at each end with a hand wheel 6", by which it can be rotated and thereby vary the distance of the standard 5 from the standard 5*. The

standards

5, 5 carry in bearings two

shafts

7 and 8, which in their turn carry the grooving rollers 9 and 10, and 11 and 12, the edges of which are held together with a pressure which may be adjusted by mechanism now about to be de scribed.

The bearings of the shaft 8, carrying the lower set, in this instance, of grooving rollers 11, 12, are slidable in guides in the

standards

5, 5", and immediately below the axis of the shaft 8 is a shaft 13 also carried in bearings in the

standards

5, 5". The shaft 13 is fitted with eccentrics 14c, 15, the eccentrio 14 being revoluble with the shaft 13 by means of a feather and groove, so that the said shaft 13 can slide endwise through the standard 5 justment of each side of with collars.

Vertical sliding bearings 16, 17 for the shaft 8 carry

adjustment screws

18, 19, the heads of which rest upon the

eccentrics

14, 15 respectively. The pressure adjustment shaft 13 is fitted at one end with means by which it can be given the necessary angular adjustment, such as with a lever 20, to cause the separation or bringing together of the grooving rollers 9, 10, 11 and 12.

The width between the grooving rollers 9 and 11 and 10 and 12 is regulated by a screw adjustment 21 working in conjunction with a screw thread on the shaft 7 the said screw adjustment moving a sleeve 22 to which the grooving roller 9 is attached, and which sleeve 22 carries a projecting flange 23, which takes between two collars 24: carried on' a sleeve 25 on which the grooving roller;11.issupported.- The sleeves 22 and and accompanies the lateral adthe standard 5, being fitted on the bearing in that standard 25 are carried upon feathers and grooves on their

respective shafts

7 and 8, so that they can be adjusted endwise thereon but must accompany the revolving motion of the said shafts.

The paper to be grooved is shown in the dot and dash lines at 26 in Fig. 2, and it will be seen that it passes over a guiding roller 27 and under a guiding roller 28, and between these two rollers it passes between the grooving rollers.

The

shafts

7 and 8 are driven at a uniform speed by means of

spur wheels

29 and 30, by a belt wheel 81, shown by way of example, or by gearing.

WVhen the apparatus is at work and the wall-paper is passing through the grooving apparatus to the printing machine, the grooving rollersare rotated and impress deep grooves from opposite sides into the paper in such positions as to register with the edges of the pattern to be printed thereon, and if these grooves show the least sign of leaving the desiredpath, one of the hand wheels 6? is turned, which traverses the standard 5, the latter carrying with it the

shafts

7 and 8 and the shaft 13, but not moving laterally the

rollers

27 and 28, the standard 5 sliding over the spindles of the said rollers. One of the rollers 28 for eX- ample, is shown at Fig. 3 where one spindle end 28 is capable of sliding through its bearing in the laterally adjustable standard 5, while the other spindle end is held by collars in its bearing in the standard 5*.

A little practice soon enables the operator to keep the grooving rollers or disks running steadily upon the exact line where it is desired to groove the paper. Paper grooved in this way is sold in the piece, and the un-' printed edges protect the piece from injury either from light, damp or other cause. They also protect the paper during thepasting operation. The tearing off of the strip leaves a beveled edge on the paper, which is especially suitable for abutting against the edge of the next piece of paper which is to be applied adjacent to it.

What I claim as my invention and desire to secure by Letters Patent is p 1. Apparatus for grooving wall-paper as it enters the printing machine to facilitate the trimming thereof; comprising two pairs of grooving rollers between which the paper passes, two parallel. shafts carrying said rollers, standards in which bearings for the opposite ends of said shafts are provided,
