METHOD AND MACHINE FOR PAPER HANGING Filed May 13, 1954 v INVENTOR. JOSEPH o. NOWAK United States Patent METHOD AND MACHINE FOR PAPER HANGIN G Joseph C. Nowak, Holyoke, Mass.

Application May 13, 1954, Serial No. 429,526 3 Claims.' (cl. 118-40) This invention is concerned with applying adhesive to wall paper prior to covering the interior surfaces'of the walls of buildings.

Because of the high costs of labor, it has become prohibitive for many people to change wallpaper in their homes and buildings. Many others are using paint. As a result, the wallpaper industry has suflered.

Some people are able to apply the wallpaper to their walls themselves; but the vast majority are unable to do so. The latter group find it diflicult in applying the paste or adhesive evenly to the paper and to cut it properly.

It is an object of this invention to provide a device for applying paste to the wallpaper as the wallpaper is being hung upon the wall.

It is a further object of this invention to provide a device that will enable a person without experience to be able to secure wallpaper to walls in a workmanlike manner.

It is a yet further object of this invention to provide a device that applies the adhesive evenly upon the wallpaper preventing ugly wrinkles from forming.

These and other objects are obtained by use of a container having therein a plurality of rollers. A roll of wallpaper is placed upon a roller. The roller is made of an extra heavy material. The roller with the paper is placed upon a special roller which applies an adhesive stimulus to thepaper as it is unrolled and placed upon the wallall in one motion.

For a more detailed description, reference is made to the drawings in which Figure l is a perspective view of the entire assembly.

Figure 2 is a plane view of the roll of paper and the grooved roller.

Figure 3 is a diagrammatic view of a side elevation of the assembly of Figure 1.

Figure 4 is a diagrammatic view of a side elevation of another embodiment of the invention.

Figure 5 is a perspective view of the track guides for the roller pins.

The tub or container comprises two sides 1, a front 2, a back 2a, and a bottom 4 in the shape of a flower box. In the models constructed, galvanized iron or aluminum is the preferred material, although a plastic or synthetic material could also serve the purpose.

At each side 1 on the inside surface is a track guide 5. This is a flange or extension that is vertical to the surface of the sides 1.

A roller 6 has pins 8 in each of its ends. These pins 8 are spring mounted inside of roller 6 as at 8a (see Fig. 2). When the pins 8 are extended, they are slightly longer than the distance between the sides 1. Accordingly when roller 6 is placed inside of the tub, pins 8 are slightly compressed against the tension of their springs 8a causing the roller to be self retaining by virtue of the pressure of pins 8 against the sides 1.

On the roller are specially designed means, namely pitched grooves 7 which allow the solution 13 to be of the proper amount on the roller. The grooves 7 control or bias the adhesive solution as it is transmitted to the surface of the paper 10, which is mounted on roller 9 from roller 6. The diagonal direction of the pitched grooves 7 enables the paste to be applied smoothly to the paper instead of being spotted and causing lumps.

Roller 9 is placed within the roll of wall paper 10. The pins 11 are mounted in roller 10 as pins 8 are mounted in roller 7. Further pins 11 have springs within roller 9, not shown, which are similar in construction to 8a and enable the roller 9 to be secured to the tub by virtue of the pressure exerted by them.

Some manufacturers turn out rolls of wall paper wherein the center is of a tiny diameter. Rather than reroll this paper, there is provided a small diameter roller 12 (Figure 4). Because the weight of this tiny roller is insufiicient to maintain the roll of wallpaper in contact with the surfaces 7 of roller 6 as the paper is being pulled, the larger roller 9 is placed above the paper as shown in Figure 4.

It is always diflicult to cut the paper after it has been attached to the wall. Accordingly a cutting guide has been arranged on the back 2a of the tub. It is indicated by the line 3 formed by the flange sections 3a and 3b.

In operation, the wall paper 10 is placed upon a roller. If the paper has a large center opening, it is placed upon roller 9. If it has a narrow center opening it is placed upon roller 12. The tub is filled with a non-staining type adhesive solution 13. It is important that this solution 13 does not rise above the lower portion of roller-,6 since too much adhesive solution would be applied upon the surface of the wall paper 10. The roller 9 and paper 10 are then placed above the roller 6 in the tub. The operator merely pulls the paper 10. As he does, the

solution 13 which contacts and coats roller 6 is trans mitted to the paper 10. The pulling of the paper 10 causes roller 9 to move in a counterclockwise direction. Because of the weight of roller 9, the forces of friction create a friction pulley efiect and roller 6 rotates in a clockwise direction. In this manner roller 6 keeps coated with the adhesive solution 13 and applies it to the paper 10. The tracks 5 allow the rollers to spin on their pins 8 and 11 respectively.

An important detail is the bias grooves 7. These grooves allow the proper amount of adhesive solution to be coated on the surface of roller 6 so that the wall paper 10 does not absorb too much. coated, it will not go on the wall properly in that it will wrinkle and be lumpy. 111 models made prior to the embodiment herein, various types of surfaces were tried on the roller 6. It was after much trial and error that the grooves 7 were found to do the job best for the' specific purpose of controlling the amount of solution.

Once the proper length of paper has been placed upon the wall, it becomes necessary to cut oil the paper from the wall. The operator or amateur paper hanger merely pushes the paper down on to the cutting guide 3 and runs a blade along the guide 3, cutting the paper in a straight line. If the paper is too long when it is applied to the wall, at least the next piece will start out with a level and straight portion.

The operation is the same for the species of Figure 4.

The dimensions of the drawing have been exaggerated to teach more easily the features of the invention.

The change in size and shape of any of the components are within the spirit and scope of this invention.

I claim:

1. A device for applying an adhesive solution uniformly to wallpaper comprising a tub, guides at each end of said tub, a first roller having two ends and a spring pin in each end, said roller mounted in said tub whereby said pins are within said guides, pitched means If the paper is over-:

on said roller for biasing the amount of adhesive solu tion coating said roller, and a second roller of a heavy weight within a roll of wall paper directly above the first roller, said second roller having two ends and a pin on each end, said second roller mounted in said tub whereby said pins are within said guides.

2. A device for applying an adhesive solution uniformly to wall paper comprising a tub, a roller having two ends, a separate pin in each end, a separate spring within each end of said roller and each connected to said separate pin, a vertical track in each end of said tub, said roller mounted Within said tub and having each pin Within said track, a grooved surface on said roller, a wall paper roll, a roller within said Wall paper roll having suflicient weight to maintain the paper in contact with said other roller and mounted in said tracks within said tub, whereby when said wall paper roll is pulled, said first roller turns and coats said wall paper with said adhesive solution.

3. An apparatus for applying wall paper comprising a receptacle with a paste reservoir, a paste applying rollermounted in said receptacle and immersed partly in said paste, said paste applying roller having pitched grooves therein for biasing the amount of paste that is to be transmitted, a separate spring pin in each end of said paste applying roller, said spring pins being under compression within a pair of vertical tracks mounted on the inside of each end of said receptacle, a roller mounted for movement in said tracks and having suflicient weight to maintain it in contact with saidpaste applying roller and upon which a roll of paper is adapted to be placed, and a cutting guide on one longitudinal edge of' said receptacle for cutting paper straight.
