1 Claim.

This invention relates to a wallpaper machine,

and has for the primary object the provision of a device which is especially adapted to assist a paper hanger in the preparation of wall paper pri-or to the application thereof to a wall or ceiling by providing a support for the roll of wall paper and permit the paper hanger to obtain any desired length of paper from the roll of Application March 24, 1943,v Serial No. 480,364

paste or adhesive into and from the drum by way of the ends thereof.

Arranged within the drum are agitators Il each in the form of an attaching strip I2 riveted or otherwise secured to the drum and groups of bladesl I Sfarranged at right angles tothe attachingstrip. The pitch of one group of blades' is reverse to the other group, of blades so that paper thus supported with adhesive or Paste' tion, reference is to be had to the following de scription Iand accompanying drawing, in which Figure 1 isa top plan view illustrating a wall paper machine constructed in accordance with my invention,

Figure 2 is a transverse sectional view illusj trating the device.

Figure 3 is a vertical sectional view` illustrating the paste or adhesive applying drum which therein of a roll of wall paper free for unwinding. The trough includes an arcuately curved wall 8 and end walls l of substantially, rectanwhen the drum 8 rotates the circulation of the paste or adhesive in the drum will be in the direction of each end of the drum. The drum rotating within the paste or adhesivewith the` agitators Il will keepthe paste or adhesive from congealing' and becoming lumpy.

Also Kduring the rotation of, 'the drum, the

outer periphery thereof will become coated with the adhesive or paste. t

The end walls l are provided with slots M extending diagonally from the drum and freely receive therein a rod or shaft I5 located slightly laterally of the drum and above the supporting shaft lil of said drum.

The rod or shaft i5' supports a roll of wall -paper i6 so that as the paper unwinds from the roll it may pass against the outer periphery of the drum 8 and under a guide pulley roller il as the paperleaves the trough, bringingabout guiar shape. The end walls are secured to the arcuately curved wall 6 to prevent leakage between said parts with the end walls extending a limited distance below the arcuately curved walls to provide rests for the support of the trough;

Rotatably supported within the trough is a paste or -adhesive applying drum 8 .partly submerged in the paste or adhesive contained within the trough. 'I'he ends of the drumv are fullyy open and have secured thereinend/ strips 8 forming journals to receive a shaft I0 carried by the end walls of the trough.

The ends of the drumfbeing substantially open will permit a free circulati/on or fiiowirof the the applying of paste or adhesive to one face of the paperv as it is unrolled from the roll of paper.

The end walls l are provided with slots I8 extending downwardly from the upper edges thereof with one slot located slightly laterally of the other slot., The slotsslidably and rotatably receive pintles i9 on the ends of a pressure roller 2B adapted to contact the paper as it travels over the drum '8. The pressure roller 20 due to the arrangement of ,the slots i8 may move freely upwardly and downwardly as well as rotate and isy positioned angularly to the drum 8. ff'Secured to one end of the roller 20 is a disc type knife 2l which overlaps one end ofthe drum 3 and coacts therewith in trimming one edge of the paper as it is fed from the trough. The angular relation of the roller 20 with respect tothe drum 9 positions the knife at an angle to one end t of the drum so that the knife coacting with said end of the drum will have a shearing or scissors action in severing or cutting the edge of the paper.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that a very' practical machine has been provided for supporting a roll of wall paper free of contact withforeign matter and will permit the paper to befed from the machine with ad hesive or paste evenly and thoroughly applied to one face thereof and at the same time trim the unfinished edge of the paper.

This will permit a paper hanger to easily and quickly preparewall paper for hanging and will y conserve both manual eiort and time. Furthermore, it will be seen that a device of the kind described is portable so as to permit placing thereof in any convenient place by the paper hanger and also clo'se to the portion of the wall or ceiling on which the paper is to bev applied.

'I'he device lwhile in operation, that is,A having the paper fed therefrom will keep the paste or adhesive thoroughly agitated to prevent congealing thereof so as to assure the proper application of paste or adhesive to the wall paper.

Referring to my modified form of invention,as shown in Figure 4, the pressure roller 20 has sub'- stituted therefor a double roller 22 supported by a shaft 23. This shaft is bent slightly intermediate its ends to support the rollers 22 at an angle to each other and applied to the rollers are disc type knives 24 similar to the knife 2 i The knives 24 coact with the ends of the drum i in trimming both edges of the wall paper as it is fed from the machine. The rollers 22 being arranged angularly with respect to each other position both knives 24 angularly to the ends of the drum 8 so that the knives will have a shearing action with said ends of the drum.

In a wall paper machine, a trough for coating material including end walls extendingl above the level of the trough, a drum rotatably mounted in the trough and partly submerged in`the adhesive and having its ends fully open to permit the adhesive to enter said drum, means for supporting a roll' of wall paper mounted on the end wallsabovethe trough and drum for manual unwinding and movement overand in contact with said drum, a roller rotatably and slidably mounted on the end walls of the trough above the latter and the drum and at an angle to the drum and adapted under its weight to force the paper against the drum. a cutting disc secured to one end of the roller and overlapping one end .of the drum and supported by said roller at an angle to said end of the drum to have a shearing cutting action therewith, and groups of blades secured to the interior of the drum for agitating the adhesive in the drum and acting to work the im adhesive toward the ends of said drum.
