7 3 Claims. 01. 33- 189) The present invention relates to apparatus for marking wallpaper in such manner that the same may be out to length after the border which bears the pattern indicating marks has been trimmed off.

Wallpaper usually has a border'at each edge thereof bearing marks which indicate the pattern limits so that-by cutting the paper in line with these marks placement .of several strips so cut on a wall, with the upper end of the several strips in a straight line, causes the pattern of the several strips to match. These marks which indi-' cate the pattern and which are usually placed on a border provided at each side of the wallpaper are removed when the borders are trimmed off, as must be done prior to placing the paper on the wall, with the result that no indication is left other than the pattern itself to permit matching of the pattern of one strip with the pattern of the next adjacent strip. Therefore, in order to permit matching of the patterns of adjacent strips it is necessary to cut the strips to length before the borders are trimmed therefrom.

The principal object of the present invention is to provide apparatus whereby rolls of Wallpaper may be trimmed and marked on the sides opposite to that bearing the pattern in order that when the wallpaper is placed upside down on a table for the purpose of receiving an application of adhesive it may be cut to length. In other words, this invention aims to provide wallpaper with pattern indicating marks on the rear face thereof at the points where it should be cut in order that by placing adjacent strips on a wall with their upper ends in line matching of the patterns on adjacent strips automatically results.

With the above and other ends in View the invention consists in matters hereinafter more particularly set forth with reference to the accompanying drawings in which Figure 1 is a. plan View; Fig. 2 is a front elevation partly in section Fig. 3 is a vertical transverse section;

Fig. 4 is an elevation of a measuring device;

Fig. 5 is a vertical transverse section thereof,

and

Fig. 6 is a perspective of a strip of paper. Like characters of reference are employed throughout to designate corresponding parts.

The numeral l designates a machine frame having a table 2 at the top thereof and a pair of rollers 3 and 4 at opposite sides of the table. The roller 3 is adapted to have a roll 5 of wallpaper placed thereon and the roller 4 is connected by a sprocket and chain arrangement 6 to a shaft 1 carrying cutters 8. The shaft 1' is adapted to be rotated through means of a hand crank 9 or may be power driven through the pulley H) from any suitable power source. The cutters 8 cooperate with the lower set of cutters ll so that when the 5:

paper is unrolled from the roller 3 on to the roller 4 the border is trimmed therefrom. This'mechanism above described represents a conventional wallpaper trimmer. g

The table 2 is provided with a slot l2 which 10 extends transversely with respect to the direction of movement of the paper thereon. Mounted beneath the slot l2 is an ink pad l3 with a cam surface It adjacent'one end thereof. A rod l5 is slidably mounted beneath the table and has 15 a marking disk l6 supported on its inner end by a flexible element l7. -When the rod I5 is manually moved toward the r'ighthand'side of Fig. 2 the marking disk is moved up the cam surface l4 and'across the ink pad l3. The cam surface l4 0 elevates the marking disk to a plane where it engages the underside of the paper extending across the table 2 and the pad 13 maintains this contact and'inks the disk edge so that an ink gear train23; Adjacent the pointer 2| gradu ations 24 are. provided, the graduations prefer- 35 ably being in foot units. The pointer-2 I may be moved manually relative to the shaft 22 to a position where it engages a pin 25 which defines the zero adjustment thereof, and such movement the gear train 23 or the disk 20.

In Fig. 6 there is shown a strip 26 of wallpaper of the pointer may take place Without disturbing 40 v i having the usual border 2'! at each side thereof.

The surface 28 between the border is that which bears the ornamental pattern and the marks 45 29 on the border represent the pattern limits. If the paper strip is cut transversely in line with 1 one of the marks 29 to form it into a plurality of strips, and such strips are placed upon a wall with their upper edges in horizontal alinement, 50 the patterns on the adjacent strips will match. The purpose of the present invention is to provide a mark 38 on the surface of the strip 26 opposite to that which bears the pattern in order that the borders 21 may be trimmed therefrom 55 and the paper out to length after the strip is trimmed. This is accomplished by rotating the roller 4 to unwind the paper roll 5 from the roller 3 and wind the same upon the roller 4, thereby causing the paper to move over the table 2 and the disk 20, being in contact therewith, is caused to rotate and operate the pointer 2|. When the pointer 2| indicates that a required length of paper has passed over the table the roller 4 is stopped. If at the time the roller 4 is stopped one of the marks 29 is opposite the pointer 3|, the rod 15 is pulled outwardly manually to actuate the marking disk and apply a mark 30 to the bottom face of the paper. If at the time the roller 4 is stopped the pointer 3| I is not in accurate alinement with one of the marks 29, the roller 4 is actuated by the crank 9 to move the paper an additional amount until the next mark 29 coincides with the pointer 3!. The rod I2 is then actuated to cause a mark 39 to be applied to the rear face of the strip. Prior to the winding of the paper upon the roller 4 the borders are trimmed therefrom and the roll of paper which is formed upon the roller 4 is removed therefrom and transferred to a table where it is placed upside down for the reception of the usual adhesive. As the paper is drawn over this table it is cut at each of the marks 30 and the adhesive is applied thereto. The patterns on the strips so formed register when the strips are hung adjacent to one another with their upper edges and in horizontal alinement.

Although a specific embodiment of the invention has been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention and such changes are contemplated.

What I claim is:

1. In a machine of the character described, a table over which a strip of paper is moved and having a recess in the top thereof, an indicator for indicating length of paper passing over said table, a roller for actuating said indicator and rotated by movement of the paper, an ink pad mounted in said recess below the top of the table, an operating member within said recess below the top of the table and movable transverse of the paper, and a roller marker within said recess to engage said pad and mark the paper upon transverse movement of said operating member.

2. In a machine of the character described, a table over which strip paper passes unwinding from one roll onto another, said table having a recess in the top thereof, a marker pad disposed in said recess and having an upper cam surface,

a marker roller arranged to ride on said cam surface within said recess and upon movement in one direction rising to mark the underside of the paper, manually operable means movable transversely of the paper to move said roller.

3. In a machine of the character described, a table over which strip paper passes unwinding from one roll onto a driven roll, means for driving said driven roll, means for supporting said driving means and mounted on said table, an indicator mounted on said supporting means and operable to indicate length of paper passing over said table, an actuating roller for the indicator and engaging and rotated by movement of the paper, said roller being mounted on said supporting means, said table having a recess in the top thereof, and a'manually operable marking device in said recess and operable to mark the underside of the paper.
