WALL PAPERING MACHINE Filed Feb. 5, 1932 2 Sheets-Sheet 2 wig Arthur Zloyd,

INVENTOR ATTORNEY Patented May 29, 1934 UNITED STATES PATENT OFFICE 3 Claims.

The present invention relates to an improved machine for papering the side wall and ceiling, and the purpose of the invention is to provide, in a machine of this kind a paste trough which will accommodate itself to the paper as it passes between a paste applyingbrush and the roller, according to the angle of the machine relative to the side wall or ceiling.

' Another purpose is to provide a machine, which applies the paper to the wall, subsequent to the application of the paste, and afterwards sever the paper at a point according to the height of the Wall or the width of the ceiling.

Another purpose is to provide in amachine of this kind a handle having a spring tensioned pivotal joint with the frame of the machine, so that the handle may assume various positions relative to the frame as the paper is being applied.

A further purpose is to provide a spring ten- 0 sioned roller cooperable with the paper for retaining it in contact with the paste applying brush, which is mounted in the paste trough.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and i combination of parts to be hereinafter set forth,

'35 of the frame of the machine in elevation, and

other parts of said frame in section.

Figure 5 is a View in elevation of the frame of the machine, showing the side thereof opposite to that shown in Figure 4.

Figure 6 discloses details of portions of the knife 51 and movable cutter 52.

Figure '7 is a detail view of one of the ears 9 .10, so that the sleeves may be adjusted in differto show more clearly how a rod 10 may be supported in a bearing of the ear, for in turn to support a roll of wall paper.

Referring to the drawings 1 identifies a frame of the wall papering machine, which may be constructed of any suitable metal preferably die drawn or die stamped sheet metal, for example aluminum, and this frame comprises a body 2, a rear wall 3 and the opposite end walls 4. These end walls have diverging arms 5 and 6, in bearings of which rollers 7 and 8 are mounted. The rollers 7 and 8 include a central rod, and a body of suitable composition, such as rubber, felt and fibre, such as will act to apply the paper to the wall. While the rollers 7 and 8 are designed to possess a proper hardness, they can not be too hard, such' as would result in an improper application of the paper to the wall. Either roll 7 or 8 may be used to roll the paper on the Wall, and thereby roll out any blisters or air pockets.

The body 2 of the frame is provided with lateral ears 9 at each end of the body, and journaled in bearings of the ears is a rod 10 for the support of a roll 11 of wall paper. The rod 10 removably fits in the bearing of one of the ears, while the other end of the rod is held against movement in the bearing of the other ear 9 by means of a spring holder 12. For instance the spring holder 'is fixed in any convenient manner at 13 to one ent positions to accommodate wall paper rolls of different lengths.

Connecting the end walls 4 of the frame are guide rods 19 and 20, over which the wall paper 21 from the roll 11 passes. The end walls 4 of the frame have vertical slots 22, and mounted in the slots are the end portions of a rod 23, on which a roller 24 is carried. This roller 24 preferably consists of a composition of rubber and felt, mostly felt, and the wall paper passes under the roller, which acts to keep the wall paper in contact with a paste applying roller brush 25, which passes through openings of the end walls of a paste trough 26. That is to say a rod 27 of the paste applying brush passes through the openings of the end walls of the trough and the ends of the rod 27 are journaled in bearings of the end walls 4 of the frame. Connected to the ends of the rod 23 are coil springs 28, which in turn are fastened at 29 to the exterior of' the end walls 4 of the frame. By means of the springs 28 the roller 24 is held in position to normally hold the wall paper against the roller brush 25. The upper ends of the slots 22 have offset portions 30, which may receive the rod 23, when the roller 24 is raised out of contact with the wall paper, so that the wall paper 21 may be passed over the guide rods 20, when another piece of wall paper is to be applied. I

The roller brush 25 rotates with the rod or shaft 27, and one end of the rod 27 has a pulley 31, with which a belt 32 engages. The belt 32 in turn passes about a pulley 33 on one of the pintles of the roller 8, so that when the roller 8 rotates by engaging with the wall paper and rolling it on the wall 34 rotary motion is transmitted from the roller 8 to the roller brush 25, through the medium of the belt 32. The belt 32 is crossed as shown in Figure 3, so as to rotate the roller brush 25 in the opposite direction to the roller 8, but in the same direction with the passage of the wall paper under the roller 24. However, due to the pulley 31 being of a larger diameter than the pulley 33 the roller brush will rotate slower than the roller 8, in which case the roller brush will act to brush the paste on to the wall paper, which passes under the roller 24 at the same relative rate of speed as the rotation of the roller 8.

The paste trough 26, due to the rod 27 passing through openings in the end walls of the trough, oscillates on the rod, therefore: will accommodate itself to the position of the frame, when the machine is used for applying wall paper on the wall or the ceiling. The fact is the paste trough is provided with weights 35 at both ends, depending from the bottom of the trough, acting to balance the trough according to the position of the machine. Suitable collars 36 are fixed on the rod 27 to hold the trough in position preventing endwise movement. Suitable collars 36 are adjustably secured on the guide rods 19 and 20 by means of set screws 37, said collars being provided for the purpose of guiding the wall paper over the rods. vIt is obvious that the collars 36 can be adjusted according to the width of paper.

On the end of the rod or shaft 27 opposite the pulley 31, a second pulley 38 .is mounted, and a belt 39 engages about the pulley 38 and in turn about a pulley 40 on one of the pintles of the roller ,7. The belt 39 is. also crossed in order to impart movement to the roller-7 in the same direction as the roller 8, that is to say when applying paper to the ceiling.

In applying paper to the side Wall 34 of a room, the wall paper having been engaged against the roller brush and over the guides 19 and 20, is pulled far enough through to lap it'over the roller 8, the paste. on the paper acting to dampen the paper sufliciently to cause it to lightly adhere to the surface of the roller, and when the machine is positioned as in Figure 1 so as to engage the roller 8 against the side Wall 34 the paste covered surface of the paper will adhere to the surface of the wall, and then by moving the frame downwardly the roller 8 will roll the paper flat against the surface of the wall, and since a handle 41 ishingedly connected to the body 2 of the frame and capable of being moved outwardly, the machine can be operated on the full height of the wall 34.

In applying paper to the ceiling, the wallpaper is pulled sufficiently under the roller 24 and over the guides 19 and 20, then over the roller 8, and then allowed to engage entire surface -of the roller 7. In this instance the machine is first placed which are pivoted at 58 to the interior of the side in the opposite corner of the room, that is the corner opposite but remote from the wall 34, in which instance the machine is drawn across the ceiling, the rollers 7 and 8 operating in the direction of the arrows shown on Figure 1.

The hinge between the handle 41 and the body 2 of the frame comprises a headed hinge pin 43, which engages through the ears 44 of the handle and through the ears 45 projecting from the bottom of the body 2 of the frame. A coil spring 46 is carried by the hinge pin 43, and ends of the spring engage at 47 and 48 with the body 2 and the upper end of the handle 41, in order to so tension the spring as to retain a lug 49 depending from the body 2 in engagement with a shoulder 50 on one of the ears 44 of the handle, thereby holding the frame normally in an upright position relatively in alignment with the handle.

A severing mechanism comprising a stationary knife 51 and a movable cutter 52 is carried by the side wall of the frame. The movable cutting knife is held in position by screws 53 passing through slots 54 of the cutter, and due to the slots the movable cutter has limited movement. The movable cutter has a saw tooth cutting edge 55, the teeth of which are beveled, and is adapted to cooperate with the straight cutting edge of the stationary knife 51. Normally the movable 'cutter 52 is positioned with its saw teeth cutting edge spaced from the straight cutting edge of the knife 51, so that the wall paper may pass therebetween. When a strip of wall paper is applied to the wall 34 at full height, the movable cutter is moved in the direction of the stationary cutter, the saw teeth piercing the paper and thereby severing it.

In order to operate the movable cutter links 56 pivotally depend from the cutter 52 and are in turn pivoted to the remote ends of the levers 57,

wall of the frame of the machine. The adjacent ends of the levers 57 are in turn pivotally connected at 59 to the upper end of a link 60, which passes through the side wall of the frame. A spring 61, which is located between a collar 62 on the link 60 and the shoulder 63 of the side wall of the frame tensions to hold the link 60 in its uppermost position, in which case the movable cutter will be held normally in a downward position with the cutting edge of the cutter 32 spaced from the straight cutting edge of thestationary cutter, to permit of the passageof the wall paper between the edges. The link 60 in turn pivoted at64 to an operating rod 65 mounted in suitable guides 66 of the handle 4. T

Obviously by pulling upon the rod 65 when the machine has reached the lower end of the wall 34 the movable cutter will operate to sever the paper, regardless of what position the handle assumes with respect to the frame, due to the 11.35 fact that the joint 64 is in close proximity to the hinge 43. The trough 26 has a cover 67 through an opening 68 of which the bristles of the roller brush operate, thelongitudinal edges of the opening 68 acting to slightly engage with the endsof the bristles of the roller brush so that therewill not be too much paste transferred from the trough to the paper, just'enough to cause proper adherence of the paper to the wall.

The invention having been set forth, what is-1'45 claimed is: Y

at remote sides of the frame,-said'frame having a course for the wall paper, a roller paste applying brush journaled in end walls of the frame, a tensioned roller constituting an element of said course for holding the paper yieldably against the brush to gauge the film of paste on the paper, a weight balanced paste trough swung on the pintles of the brush, whereby the paste gathered by the brush may be applied to the surface of the paper traveling through the course, and means carried by the frame for the support of a roll of wall paper, the paper from which passes through the course and is engaged with one or both of the papering rolls, means operatively connecting the roller brush and the papering rolls for transmitting revoluble movement from the latter to the former, said frame having guide.

slots in its ends for the reception of pintles on the tensioned roller, said guide slots having offsets at their upper ends to receive the pintles to hold the tensioned roller in an inoperative position.
