@FFEQE 1 Claim.

This invention relates to paper pasting apparatus, and more particularly to a wall paper pasting machine.

An object of this invention is to provide an 5 exceedingly simple and portable pasting machine which is very light in weight and which can be operated by any desired power means.

Another object of this invention is to provide a paper pasting machine of this kind which is so constructed that it will paste and fold any desired quantity of paper in a relatively short time so that a paper hanger will not waste undue time in the preparation of the paper for the wall.

A further object of this invention is to provide a device which will not injure or otherwise smear the exposed surface of the wall paper during the pasting thereof.

The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein:

Figure 1 is a detail top plan view of a device constructed according to the preferred embodiment of this invention.

Figure 2 is a sectional view taken substantially through the transverse center thereof.

Figure 3 is an end elevation of another form .30 of pasting roller.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally a reservoir or receptacle which is open at the top and which is adapted to receive a quantity of paste. This receptacle 10 is of any desired length and width and is relatively shallow.

A lower pasting roll 11 is journaled in a pair of uprights or frame members 12, which are secured by means of bolts 13 or the like to one wall of the reservoir 10. The roll 11 is adapted to be partially submerged in the paste positioned in the reservoir 10, and this roll 11 may have either a smooth surface or have the surface thereof provided with longitudinally extending and circumferentially spaced ribs so that a quan 'ty of paste will be picked up by the ribs as the roll 11 is rotated. ()ne end of the shaft 14 of the roll 11 extends through the side of the reservoir 10 and a crank or other power means, not shown, be connected to this extended shaft so as to rotate the roller 11.

An upper roller 15 is also journaled in the uprights 1 and is adapted to firmly hold a strip of paper into contact with the periphery of the pasting roll 11. This upper roll 15 may be constructed of metal or other relatively hard mate" rial so that it will not injure the exposed or outer face of the wall paper but will hold this paper firmly into contact with the lower roll, so that the paper will be drawn through the two rolls upon rotation thereof by the power member conneoted to the shaft 14. i

In order to support a roll of wall paper in a position where the paper may be readily drawn between the two rolls 11 and 15, I have provided a pair of bracket arms 16 having an angularly disposed inner leg portion or base 17, which is secured by means of bolts 18 to the opposite or rear wall of the container 10 from the frame 12.

These bracket arms 16 have mounted in the outer end portions thereof trunnions or stub shafts 19 which are adapted to have lateral sliding movement in the outer end of the arms 16 and are constantly urged inwardly by means of a coil spring 20 disposed about the shaft or trunnion 19, one end of the spring 20 engaging against one face of the bracket 16 and the other end engaging against an annular flange 21 carried by the 30 trunnion 19. This flange 21 is adapted to engage against the end of the roll so as to hold the turns of the paper against lateral movement and to prevent free unrolling of the paper while permitting the paper to be readily drawn through the two rollers 11 and 15.

A brace 22 which is provided with outturned opposite end portions 23 is secured to the bracket arm 16 and is disposed inwardly of the outer ends thereof so as to prevent spreading of these bracket arms and permit the use of relatively light material which will be rigidly held against spreading by the use of this bracing member 22.

A collar 24 is secured to the outer end of the stub shaft 19 and bears against a bearing 25 carried by the outer end of each bracket arm 16 and within which the stub shaft 19 is rotatably mounted. This collar 24 provides means by which the tension on the spring 20 may be suitably adjusted and so that the roll of paper mounted 10 on the trunnionsl between the flanges 21 will be positioned properly to guide the paper through the rollers 11 and 15. As shown in Figure 3, the lower or pasting roll 11 may be provided with longitudinally extending ribs 26, which may be constructed out of hard rubber or the like.

In the use of this device, the roll of paper may be mounted on the paper roll supporting means including the brackets 16 and the trunnions 19 and the free end of the paper with the outer sur- 1 face disposed upwardly trained over the top of the brace 22 and the rear edge of the reservoir and disposed between the two rolls l1 and 15. Preferably, the diameter of these rolls is such that a single turn of the lower roller 11 will pull through a length of paper substantially equal to one foot so that if desired, a suitable signal means may be connected to the operating shaft 14 so that it will not be necessary to count the turns of this roller 11.

After a length of paper equal to substantially a foot has been drawn through the rollers 11 and 15, the free end of the paper is lightly pasted against the adjacent wall of the reservoir 10 and the shaft 14 rotated additionally so as to draw additional paper through the rolls. By pasting the free end of the paper against the side wall of the reservoir 10, a fold is formed in the paper and this free end then releases itself from the side of the container after a small additional quantity has passed through the rolls and this free end then pasted against the moistened surface of this additional paper. As the roll 11 is rotating, the paper will then fall onto the first paper in folds with the pasted portion of each fold contacting one with another. When a sufficient quantity of paper .has been drawn through the rolls, it may be cut oif and the stacked .folds carried in one hand and then placed on the wall or ceiling in the usual manner.

The wall of the reservoir 10 adjacent the rollers 11 and 15 is disposed at the desired height relative to the paper passing through the rolls so that the pasted paper will engage the upper edge of this adianent'wall, and this wall acts as a wiper so as to wipe unnecessary paste from the bottom surface of the paper passing thereover. In this manner, the paste will be spread evenly over the bottom of the paper and the paste scraped off of the paper will flow back into the reservoir 10.

It will be noted from the foregoing that in the pasting of the paper, .it is not necessary to cut oi the length of paper equal substantially to the height of the room or the length of the ceiling, but that a consider-aide quantity of paper may be pasted at one time and this paper carried in one hand and then cut off as the desired lengths are placed on the wall or ceiling. It is, of course, understood that in the use of the paper, the paper is initially trimmed, but this trimming is preferably done as the roll of paper is being manufactured.

It will be noted from the foregoing that an exceedingly simple and very light paper pasting means has been provided whereby the pasting of the paper is facilitated and whereby it is not necessary in the papering of a room for two or more paperhangers to be present inasmuch as the paper .can be pasted as it is needed, and any desired quantity of paper can be passed through the rolls and then placed on the wall after which it may be cut the desired length,

'It is, ofcourse, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is:-

A paper pasting means comprising a container of substantially rectangular configuration, a pair of contacting rollers, a pair of bearing blocks for said rollers disposed within said container and engaging against opposite ends of said container and one side of said container, means for securing said blocks against movement, a pair of brackets secured to the opposite side of said container and disposed exteriorly thereof, a trunnion rotatably carried by each bracket, paper roll engaging plates carried by each trunnion, a spring about each trunnion engaging against said bracket to constantly urge said trunnions and plates inwardly to support a paper roll therebetween and to yieldably resist turning of said paper roll, the upper edge of the side carrying said brackets constituting a guide means for guiding the paper toward said rollers, and paste wiping means carried by the edge of said cantainer closely adjacent said rollers.
