Patented May 6, 1941 MACHINE FOR PREPARING WALL AND CEILING PAPERS FOR HANGING Beatrice Maud Thomas, Pendlebury, Manchester, England Application January 3, 1939, Serial No. 249,025 In Great Britain January 13, 1938 6 Claims.

This invention relates to machines for preparing for hanging, lengths of paper to be used as coverings for walls and ceilings, and has for its main objects to provide improved means for applying adhesive .to the paper and for obtaining adhesive-coated lengths in a convenient manner for folding; for trimming the selvedges of the paper; for measuring or marking-01f pre-determined, pattern-matched or other lengths of paper; for guiding the paper as it passes to the trimming means; for severing the measured lengths of paper, and for cutting strips or bands of narrow-width paper. A minor object of the invention is to provide all these improvements in combination in a portable, collapsible machine which may be conveniently carried from place to place where the paper-hanging is to be done, and may readily be set up for use in those places.

In the accompanying drawings, the various features of the invention are illustrated by way of example, both in combination in a single machine, and separately for use selectively, since any one or more of the improvements may be adopted independently of the others.

Figs. 11 to 14 are end views of various forms of strip severing or marking means.

Fig. 15 illustrates a still further alternative for strip-severing or marking.

Referring to Figs. 1 and 2 more particularly, the improved machine, in the form illustrated,

comprises an operative portion denoted generally by the reference A and a supporting portion denoted generally by the reference 13, these two portions being detachable one from the other.

The operative portion comprises a framework having end plates or castings l and three tie bars or rods 2, said rods having screwed ends on which the end plates are located between nuts 3. Alternatively the tie rods could have reduced ends or could carry shorter tubes, and the plates be located against the shoulders formed by the larger diameters of the tubes. Supported on the two lower tie bars 2, and held in position by screws 3 in the end plates I, is a trough 4 for the adhesive, in which trough is rotatably mounted a pasting roller 5. The said roller 5 is carried in bearings 6 on the ends of the trough 4, the trough, bearings, and roller, being removable as a whole from the framework, and one of the bearings 6 being open so that the roller may readily be removed from the trough. As shown, the trough has a part of its upper wall cut away at 4 to facilitate its being filled, and has its end parts of narrower width (for a purpose hereinafter set forth), and it is also provided with reinforcements on its under face to contact with the tie bars 2 on which it is supported; The pasting roller 5 is covered with a coarse woven fabric to assist in carrying adhesive.

Above the pasting roller 5 is a pressure roller 1, this being shorter in length than the pasting roller and shorter than the normal width of paper to be treated, and having extended hollow trunnions 5 by which it is mounted on a nonrotating rod 8, the ends of the rod normally lying in open slots 9 in the upper edge of the end plates 1. Such pressure roller 1 is drawn against the pasting roller 5 by means of springs til, which operate between the said rod 8 and abutments ll engaging the lower edges of the end plates l. Adjacent the said open slots 9 are shorter slots I2 in upwardly extending parts of the end plates l, into which shorter slots the rod 3, carrying the presure roller, may be placed when it is desired to release the paper or pasting roller from pressure, the said spring [0 then serving to retain the rod 8 in such shorter slots.

By making the pressure roller shorter in length than the pasting roller, and shorter in length than the width of the paper to be treated, there is no risk of its picking up adhesive from the pasting roller and transferring it to the pattern side of the paper. 7

On the ends of the pasting roller, are serrated raised parts [3, and on the extended trunnions of the pressure roller are rubber-tired discs [4, these being slidably keyed to the said trunnions so that when in one position they will ride on the said serrated parts [3, and thus lift the pressure roller slightly from the pasting roller, which results in there being a heavier layer of adhesive applied to the paper, whilst when in positions clear of those raised parts I3, they allow the springs II] to have their full eifect on the pressure roller. The .said .abutments .H, to which the springs I 3 are connected, are, in actuality, the ends of a rod l5, extending across the machine below the trough 4, and. the lower faces of the. end plates I are serrated or scalloped to receive such rod in a number of varying positions with respect to the pressure roller I, each of which positions brings about a different degree of tension in the springs I0, and thereby varies the compression of the rubber tire of the discs I 4 and of the raised parts I3 on the pasting roller 5, to vary the amount of adhesive applied to the paper.

Projecting inwardly from each end plate I, is a cranked. spindle It, adjustable inwardly, outwardly and rotatably, being held in the set positions by the screws I7, and each such spindle carries at its inner end a flexible flap I8 adapted to .bearagainst the margins of the paper as it passes around the pressure roller 1, and thus removeany surplus adhesive.

Mounted in bearings I 9 in the end plates I is a supporting roller 20, the end and centre portions of ,whose periphery, at least, are roughened, as by knurling. Within each end of such supporting roller, at a distance from the extremity, is a wall 2!] which, in addition to supporting the As shown in detail in Fig. 6, there is provided a roll-supporting rod 32, rotatably located in externally-screwed bushes .33, each of which bushes has two parallel faces by which it is nonrotatably but slidably held in the slots 34 in the .the placing of a roll of paper on the rod, that end of the rod being bluntly pointed. By preference, the removable bush 33, is held captive to the end plate I, as by the chain 31 and nut 38.

roller on the spindle 2!, serves as an abutment for a compression spring 22.

formed with-a keywayat its ends, and each end As will be seen more particularly from Fig. 4, the spindle 2| is carries a slidable cutting disc 23 which, by the The said boss or hub 25 carries at its inner extremity a rubber tire 21 adapted to press against theroughened surface of the supporting roller 20, or the paper thereon, and the boss, with the cutters and the tire, is maintained in position against the pressure of the spring 22, by a bracket 28 which is slidable on the stud 28 and I may be held in any desired position by the screw 29. The bracket 28 has two fingers 33 and 3i, the lower one of which, 30, is the wider and is curved downwardly to direct the severed selvedge or margin downwards through the frame, whilst the upper one, 3 I, is the narrowerand lies over the upper tie rod 2 to prevent accidental rotation of the bracket 28 about the stud 26, due to the weight of the selvedge-guiding finger, should the screw 29 be left loose. The front portion of the trough 4 is foreshortened at the ends, as above explained, to accommodate the selvedge-guiding means whilst allowing the trough to rest on the adjacent tie rod 2.

From a consideration of Fig. 4, it will be ob- W served that, for each edge of the paper, the two cutters 23 and 24, together with the rubbertired boss 25, which acts as a driver for the upper cutter, and also the selvedge-guiding finger 30, may be moved as a single unit to any desired position firstby the mere slackening of the screw 29 and then by either allowing, the spring 22 to move the'um't outwards or by pushing the unit inwardsyuntil the desiredposition is reached, whereupon the screw 29 is tightened again.

Carried in. forwardly-extending parts of the endplates I, is the means for receiving the roll o'fip'aper to be) treated and, forguidingit tothe selvedge trimmers, such means being adjustable to various width of paper.

, Each bush 33, is fitted at the inner end, with a fiyer plate 33 loosely rotatable thereon, and each bush is provided also with a disc-like nut 40, which nuts, by being screwed back against the inside faces of the end plates I, determine the distance between the two fiyer plates 39, which plates therefore may be screwed close up to the ends of the roll of paper and prevent lateral movement of the paper with respect to the selvedge trimmers. The propinquity of the flyer plates 39 and the selvedge trimmers 23, 24, ensures the continuous register of the selvedges with the trimmers.

Extending across the machine and carried by the end plates I, is a grooved bar 4|, the purpose of which is explained below, whilst parallel with and in close proximity thereto is a further bar 42, of square section for the greater part of its length, but of round section for a short distance near each end. The bar 42 may carry some or all of a number of devices such as are illustrated in Figs. '7 to 15. All such devices have a body 43, with a square hole to slide on the bar 42 whereby they are held in operative position, as

I in Figs. 7, but when moved onto. those parts of the bar 42 which are ,of round section, they fall toan inoperative position, as inFig. 9. 'Alternatively the body, 43 mayhave an open slot so as to be passed over parts of the bar'42 of smaller section, and then moved endwise to engage the parts of larger section.

One of such devices comprises a pair of cooperating cutting discs 44 in spring-pressed engagement with each .other, which may be employed for severing the web fofpastedpaper into narrow-width bands as illustratedfor example in Fig. 9. This operation is to be distinguished from selvedge-trimming, since the latter cannot be carried out eifectively inamachine of this class, on paper whichhas been pasted Another of such devices consists of a spiked roller 45 suitable forperforating papers which cannot conveniently be dealt with .bythe cutters '44, of which perforating'devices theremay be two; whilst other devices comprise the ,knife lade 46, the wire markerAI, thepencil 48 and the marking wheel 49;, The marking devices may, as illustrated in Figs. 13 and 14, be arranged for use before as well as after pasting, since they do not pierce the paper and'therefore would not allow adhesive to reach thepattern side. Referring again toFig, 2 there is shown a collapsible measuring device 50, for examplea telescopic or an articulated member,.one.end of which is detachably'held in jaws 50?.ih one of the end plates I. On theother end plate I, substantiallyopposite the jaws 5B? is formed a small horizontal web part 53* for a purpose hereinafter explained. I

The--supporting portion of the machine comprises the box and lid 5|, 52, of a carrying case, hinged together at one end and these are adapted to contain the operative portion (including the collapsed measuring member 55) and the table described below.

The box and lid 5!, 52, when in the supporting position, constitute parts of an A frame, held in fixed angular relation by the link or hook 53. On the upper end of the lid 52 are projecting cars 54, under which one of the lower tie bars 2 of the operative portion may engage, the other lower tie bar resting on the box 5! (see Fig. 1). Extending from the box 5|, and detachably housed in sockets 55 thereon, are two arms 56, on which is slidably placed a hinged table 51, stops 58 limiting the approach of the table to the operative portion of the machine. The table 5? is in two parts hinged together to allow its being placed in the box or lid.

In operation, for preparing full Width wallpaper for hanging the rod 32 is lifted to detach the loose bush 33 from the end plate I, the bush is then drawn from the rod 32, the roll of paper is placed upon the rod 32 and the parts 32 and 33 are then replaced. The flyer plates 39 are urged against the ends of the roll of paper by means of the nuts 40. The selvedge trimming cutters 23 and 24 are then set to the correct position for severing the selvedges of the paper on the roll, the paper is fed between the rubber tires 2! and the supporting roll 20 to effect such severance, and from thence it passes between the pasting roller 5 and the pressure roller 1. The flexible flaps l8 wipe the margins of the trimmed paper, and the paper may then be drawn forwards over the pressure roller I and over the operative part of the machine towards the table 51.

It will thus be seen that the machine is operated merely by drawing the paper through it, and that the pasted paper emerges from the machine in a substantially horizontal direction with the pasted side uppermost. This lends itself to the usual custom of paper hangers, according to which a pasted length of paper is given a long fold at one end and a short fold at the other end to facilitate its being carried to the wall or ceiling to which it is to be affixed. By drawing the paper over the table 5! to the correct distance and then folding back the outer end so as to lie in a double width on the table, and by then severing the paper from the supply roll by drawing the rotating knife 59 along the grooved bar 4 I, and thereafter folding back the severed end so as to lie over the central part of the severed length, the paper is in the disposition usually adopted in the hand treatment of paper, that is with a long fold and a short fold. The table, as will be seen from Fig. 1, need only be quite short, even for out lengths of several feet.

Should it be desired to obtain narrow width strips, say half width strips, the rotating cutters M are placed in the desired position, and the paper, on leaving the pressure roller 1, passes between such cutters and is thereby divided longitudinally.

Assuming the paper to be a patterned paper, the side-by-side lengths of which are to be matched, the improved machine facilitates such matching. When threading up the machine, a distinctive portion of the pattern is cut from the paper and fixed on the horizontal web 50 of one end plate, and the paper is then drawn from the machine to the required length which has been marked at 59 on the collapsible measuring device 5!). Before severing, the paper is now drawn a further distance until the part of the pattern on the said horizontal web 50* has its replica in line in the length of paper. The point to which the free end of the pasted strip now extends is marked on the measuring device 50 at 60, and for further lengths it suflices merely to draw the paper each time to such further mark 51 and then sever it on the grooved bar 4!, the distance between the first and second markings representing the surplus required to effect matching of the pattern.

In a modification not illustrated the grooved bar 4| and the bar 42 may be combined into one, but this may necessitate the removal of the adjustable devices before severance of the pasted strip can be effected.

What I claim is:

1. In a wall paper pasting machine, a pasteholding trough, a pasting roller rotatable therein, a pressure roller above the pasting roller, the pasting roller being of greater length than the width of paper to be treated, and the pressure roller being of shorter length than the width of the paper to be treated, and flexible means for wiping the margins of the pasted face of the 7 paper as it passes around the pressure roller, for delivery in a substantially horizontal position, pasted side uppermost.

2. Means according to claim 1 wherein the trough and pasting roller is removable from the machine as a Whole, whilst the pressure roller is independently mounted in the machine.

3. Means according to claim 1, wherein the pasting roller and pressure roller have co-acting resilient parts, and wherein adjustable tensioning means is provided to vary the compression of such resilient parts to vary the amount of adhesive applied to the paper.

4. A wall paper pasting and trimming machine, according to claim 1, having a support extending across the machine beyond the pasting roller,

and having means adjustable along the support for marking the pasted strip to obtain narrow width lengths, the support being of varying section, so that the means for marking the paper are held in an operating position when on a part of one section, and fall to an inoperative position when on a part of another section.

5. A wall paper pasting and trimming machine, according to claim 1, having a support extending across the machine beyond the pasting roller, and having means adjustable along the support for severing the pasted strip to obtain narrow width lengths, the support being of varying section, so that the means for severing the paper are held in an operative position when on a part of one section and fall to an inoperative position when on a part of another section.

6. A wall paper pasting and trimming machine, according to claim 1, having a support extending across the machine beyond the pasting roller, and having means adjustable along the support for perforating the pasted strip to obtain narrow width lengths, the support being of varying section, so that the means for perforating the paper are held in an operative position when on a part of one'section and fall to an inoperative position when on a part of another section.
