The present invention relates to apparatus for applying an adhesive coating to one surface of paper or similar material wound into a roll, and the primary obj ect of theinvention is to .provide an improved pasting machine for applying paste to wall paper or the like.

A. further object of the invention is to provide an improved paste applyingdevice forV wall paper embodying an arrangement lo wherebyan even coating of paste is applied to one surface of the paper and drawn inl strips of anylength from the device.

A further object of the invention resides in the novel cutting means allowing cutting l5 of theV pasted paper to any desired length andl retaining the cut end of the paper in a position to be readily grasped for drawing further lengths of paper from the supply roll.

A further object of the invention resides in the provision of a pasting machinel for wall paper and the like, adapted to bepositioned upon one end-of a paper hangers tablel so as to permit relatively long lengths of pasted paper'to bedrawn from the machine and folded. in 4the usual manner preparatory to hanging. f

A still further object of the invention is to provide a device of this character which is of extremely simple construction, one allowing easy and thorough cleaning of the paste container, andv one which will not tilt as'the paper is being drawn from the machine.

Other objects and advantages of the invention will be apparent during thecourse of the following detailed description, taken in connection with the accompanying drawings forming a part ofthis specification and in which drawings: j 1' Figure 1 is a top plan view of the pasting machine showing fragmentary portions broken away for illustrating details of construction.

' Figure 2 isa View part in side elevation and part in longitudinal' section showing'the manner in which the paperis Vfed thru the pasting rollers. j

Referring to the drawings in detail. and wherein similar reference characters designate corresponding parts thruout the several views, the improved paper pasting machine has been shown including a box-like frame or casing 5 having a flat bottom wall 6, vertical side walls 7 and a rear end wall 8. f The frame 5 may bey formed from sheet metal or any other suitable material-and each side A wall 7 is provided adjacent therear wall 8 with an upwardly projecting extension 9 the forward edges of which are preferably inclined and extend to a pointbelow the upper edges Aof the side walls 7 providing-notches or 60 recesses 10in the upper edge of eachside wall at the forward ends of the extension plates 9. The lforwardvor kfront end of the frame 5 is left open and at the forward end of each. side wall 7 is formed an upstanding arm 11 65 forming bearing mountings yfor, a removable roll supporting shaft 12, adapted to support a roll of wall paper 13 between the forward ends of the side walls 7. l

`Secured with-a sealed joint between the side walls 7 is an upwardly and rearwardly inclined plate 15 the forward lower edge of which is secured'with a sealed joint to the bottom wall 6. The rear upper end of the inclined plate 15 extends slightly beyond the 75 forward edges of the recesses 10 at a location spaced below the upperedges'of the side walls 7 as clearly'shown in Figure 2. This rearwardly inclined plate 15 aside from forming a guide for the paper unwound from the roll 13, forms a paste reservoir or con-v tainer 16 for receiving paste adapted to be applied to one surface of the wall paper.

` AFiXedly mounted upon a shaft 17 suitably journaled in the side walls 7 slightly rear- S5 ward and below the recesses 10 is a kpaste applying roller 18v arranged to have its lower portion rotate in the paste contained in the reservoirl. The roller 18 is arranged to project slightly above the upper rear end of the inclined plate 15 and below the top edges of the side walls 7. By observingFigure 2 it will be seen that with this arrangement that the paper will be guided between the side walls 7 over the upper side of the roller 95 18 so that paste adhering to the circumference of the roller 18 will beapplied to one surface of the paper passing over che roller. A wiper isprovidedfor removing excess `paste from the rollerf18 and this wiper'is 100.

preferably in the form of a wiping brush including a brush bar 19 mounted between the side walls 7 beneath the rear portion of the inclined plate 15, and which brush bar carries suitable tufts of bristles 2O arranged in wiping engagement with the circumference of the roller 18.

FiXedly secured upon a shaft 22 journaled in the side walls 7 rearwardly and above the pasting roller 18 is a return roller 24 the circumference of which is spacedy slightly from the circumference of the roller 18.

' This roller 24 aside from serving to retain the paper in contact for a portion of the' circumference of the pasting roller 18 serves to returny the paper passed thereabout to a direction extending above the supply roll 13 with the pasted side of the paper uppermost.

Mounted upon one projecting end of the pasting roller shaft 17 is pinion 26 for meshing with a pinion of like diameter 27 fixed to a projecting end of the shaft 22 on which the return roller 24 is mounted. This positive drive coupling between the rollers 18' andL 24 insures rotation of the pasting roller 18 when a pull is exerted on the pasted portion of paper 28.

Cutting? means isp'rovided for cutting` off desired lengths of the pasted paper', and this i cutting means consists of a pivoted U-shaped cutter' mounted to be swung ,into and out of a cutting position. The cutter includes a cutter bar or blade 30 connected between arms 31 pivotally mounted as at 32 to the outer sides of the extension plates 9. The blade 30 is of a length slightly greater than the width ofthe frame and the arms 31 are of such length that when the cutter is swung into a cutting position as shown in dotted lines in Figure 2'the cutting edge of the blade will be disposed above the rear edge portion of the inclined plate 15. In full lines in Figure 2 the cutter has been shown in its inoperative position resting upon the f upper' edge of the side walls 7 rearwardly ofk theextension plates 9.` The recesses will permit of the cutting edge of the blade 80 engaging the upper edge of the plate 15 so that the paper may be readily torn on a line along the blade.

An expansion coil spring 35 preferably encircles the shaft 12 between one end of the roll 13 and one of the arms 11 for normally urging the roll into engagement with one of the side walls 7. This arrangement insures straight feeding of the paper along the inner surface of one of the side walls.

rlhe pasting machine may be of about twelve inches in length and in use is intended to be placed upon the upper' side of a paper hangers Vtable adjacent one end thereof. The shaft 12 may be removed and inserted thru the roll of paper to be pasted and after which the shaft is mounted in the arms 11 withl the roll unwinding from its lower side.

The end of the paper is trained over the roller 18 and beneath and about the roller 24 which returns the end 28 above the roll 13. With paste in the reservoir 16 it will be seen that when a pull is exerted on the end 28 that an even coating of paste will be applied to one` surface of the paper. After theV paste has been applied to a suitable length of the paper, the cutter is swung forwardly engaging the pasted paper end 28 and pressing the same upon the run of paper 40 along the reary upper side of the inclined plate 15. The

paper may then be torn along the blade 30 leaving a short runY of paper extending from the blade upwardly over the roller 24 which may be easily grasped for drawing further lengths of paper from the roll 13. This short run of pasted paperV is shown by the dot and dash line 42 in Figure 2.

The inclined plate 15 aside from permitting increased capacity of the paste reservoir' 16 provides a rest for the blade 80 during the cutting operation, permits of a guidey way being formed between the roll 13 and pasting roller 18 for the run lof paper 40, and also permits proper mounting of the wiper brush.

Since the upper sidev of the reservoir 16 is open it will be seen that the reservoir may be very easily refilled and that thorough clean? ing of the paste reservoir may bev readily accomplished.` By having the paste: reservoir and pasting and cutting devices arranged at the rear portion of the frame 5 it will be seen that there is little likelihood of the machine tilting upwardly at its rear end when a pull is being exerted on the paper in a direction forwardly of the machine.

From the foregoing description it willl be apparent that a novel and improved construction for paper pasting machines has been provided which is of extremely simple and durableY construction and one which may be easily operated for applying an even coating of paste to any desired length of wall paper.
