Be it known that we, WILLIAM J. DUNN and HENRY B. TAYLOR, 'bothof the city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Wall- Paper-Hanging Devices, of which the following is a full, clear, and exact description.

This invention relates to improvements in wall paper hanging devices and the object is to provide a simple and inexpensive machine which will quickly and easily hang, accurately trim and paste the paper.

A further object is to provide a device which will hold the trimmed and pasted paper conveniently for matching the pattern of the paper already hung, and which will cut the paper transversely when the pattern has been matched.

A still further object is to provide means for cutting the paper to any width when working around door, windows, etc.

Another object is to provide a machine of this character which may bequickly'and easily adjustedto any height of room or any standard width of paper, and which may be operated from the floor.

To accomplish these, objects,

the'floor, having at the top thereof a paper handling device driven by a suitable belt from a pulley conveniently located on-the support. The paper handling device comprises a paper roll support, a pair of feeding rolls having trimmers on the ends thereof, a paste reservoir containing a revolving drum over which the and finally a pair of discharge A manually controlled cutter is provided outside the discharge rolls for severing the trimmed and pasted paper after the same is adjusted to position on the wall.

In the drawings which illustrate our inventionand throughout all the figures of which similar numerals refer to corresponding part-sz-F1gure 1 1s a general slde elevation of the device in operation. Fig. 2 is an enlarged side elevation of the paper handling device. Fig. 3 is a vertical section of the paper handling device, on the line 10-11 of Fig. 4. Fig. 4 is a plan view of the paper handling'device. Fig. 5 is a front elevation of the same, partly in sec- "rolls showing the trimmers.

front elevation of he adjustable cutters in I operative relation. Fig. 8 is a fragmentary section on the line 12 13 of Fig. 2, and shows the method of suspending the paste reservoir. Fig. 9 is an enlarged detail view of the support extending device.

In the drawings, 14 designates the base I upon which the machine stands, 15 the lower tubular members of the support, and 16 the upper members of the support which telescope within the'lower members and are preferably solid. A small housing 17 fixed near the top of each of the tubular members 15, and each contains a gear 18 .which meshes with teeth 19 formed on the members 16 so that the said members constitute reciprocatable racks. A crank 20 is provided for rotating the gears to raise the rack members 16,- and small pawls 21 to hold the gears againshrotation are provided in the housings 17 Mounted on the upper ends of the racks 16, are a pair of similar side-plates 22 connected at the back byrods 23 to form the framework of the paper handling device. At the front of the framework, a. loose paper supporting spindle 24: is mounted in the L'-shaped slots removable for the 26 of paper. The

25, so as to be readily insertion of a. fresh roll space between-the plates 22 is sufficient to allow the insertion of the widest standard paper used but, in case it is desired to use narrower paper, a small guide plate 27, such as shown in dotted lines in Fig. 5, may be placed on the spindle 24: to keep the shortrroll in proper position. Above and behind the indle 24, is a revoluble shaft 28 on wh1ch is mounted an adjustable paper guide 29, which may be shifted along the shaft according to the width of paper used. The shaft 28 itself forms a guide over which the paper passesto the feed rolls 30 and 30", arranged one above the other. On each end of these rolls the trimmers are mounted, each trimmer comprising a frusto-conical roller 31 fixed to the upper or drive roll 30, and a. grooved roll 32on the lower roll 30, cooperating with the fnusto-conical roller to form shears w ich trim of the margins of the paper and leave the edges perfectly smooth and parallel in order that the paper one end of the feed rolls are fixed as to' position, while those on the opposite ends are ad ustable to accord with varying widths of margin or varying widths of pa-- per. In order to render the adjustment possible, the body of the rollends'a considerable distance from the side plate 22 0 that the trimmers may be readily shifted on the roll spindles 33. The upper trimmer is locked tothe spindle by a set screw 34, while the lower trimmer. is loose on the spindle but is held in engagement with the upper one by alight helical spring "35. compressed between itself and the end of the roll. This arrangement best shown in- Figs. 4 and 6.

The pasting device consists of a paste reservoir 36 containing a large partially submerged roller 37 which is made hollow and open at the ends so as to leave the maximum of space for the paste. This roller is mounted on a shaft'38. The ends 39 of the paste reservoir extend upwardly to the top of the side plates 22 and are hooked over the same so as tosupport the paste reservoir, the turned over portions being seated in depressions 39 in the plates 22. The shaft 38 is mounted in bearings 40 seated in slots in the. ends of the reservoir and plates 22. These bearings are flanged inside and out, as shown best in Fig. 4, and are-accurately fitted so as .to prevent leakage from the reservoir. The front edge of the reservoir is provided at the ends with recessed lugs 41 adapted to support a shaft 42 carrying the paste scraper 43. -The scraper 43 is in the form of a plate which is approximately balanced across the shaft 42, the rear edge thereof extending into contact with the roller 37 and'the front edge lying adjacent the-feed rolls 30 and 30*, so as to form a table to guide the paper when the same is being inserted in the machine. The front portion 44 of each end of the scraper is turned around the shaft 42 to hold the scraper in place. At each end of the scraper is a rearwardly projecting lug 45 which engages the ends of the paste roller 37 andscrapes the paste therefrom so that surplus paste will not be deposited on the edges of the paper where itwould squeeze through the joint when the paper is pressed against the wall. The amount of paste supplied by the roll 37 is regulated by the scraper, which may be raised or lowered by turning the finger nuts 46. These nuts 46 are grooved to engage pins 47 projecting from the ends of the reservoir and are thereby held against reciprocation, so that by turn ing the nuts, the threaded rods 48, pivotally attached to the scraper on which the nuts are mounted, will be moved vertically to adjust the scrapen The rods. 48 are pivotally attached to the scraper in order that they may be easily swung inwardly to disengage the nuts from the pins 47 and allow the scraper and shaft 42 to be readily lifted from the lugs 41 for cleaning, or for the removal of the roller 37. By first removing the heavy idler roll 49 which is'mounted in slots 50 inthe reservoir ends and plates 22,

the entire pasting device, comprising'the reservoir, paste roller and scraper, may be lifted out of the machinein one operation and without in any way disturbing the paper in the machine. This feature'is of great convenience for cleaning or filling. the

device while in operation, and also greatly facilitates the changing of paste rollers and scrapers when a different width of paper is to be used. This changing of the paste roller for different widths of paper is necessary' as the rollermust be of such length as to deliver paste to within, say, 3 2' of an inch of the trimmed edgeof the paper to allow. I

is pressed against the wall. If the paste for expansion of the paste when the paper roller'is larger, the paste is delivered to the very edge of the paper and, if it does not immediately flow over the edge of the paper,

it will do sowhen the paper is hung and thus mar the finished work. Each length of paste roller requires a correspond ng scraper inorder to keep the ends of the roller free from paste. To overcome. the

necessity of having different. rollers for different widths of paper, the roller 37 isprovided with one or. more removable sections 37, which may be slipped off the shaft 38 and thus shorten the roller for use with narrow paper.

A de plate 51 is fixed between the plates 22 in front of the feed rolls and serves to guide the paper between the rolls when the machine is being prepared for use.

Between the guide plate 51 and the shaft 28, a pair of shafts 52 and 52 are journaled one above theother, in the plates 22, and

each carries an adjustable cutter, which cut- I ters cooperate to cut the paper to any width when working around doors and windows,

. or in corners. The cutter 53 on the upper graduated shaft 52 is adjustable to any point on the shaft where it may be locked by means of a set screw 54, while the cutter 1 p leng h whi e t e pper roll is formed of aplurality of short rollers or wheels 60 spaced well apart on the shaft 61. These rollers in a horizontal line with the contacting surfaces of the discharge rolls, is a horizontal cutting table 63 having a longitudinal slot 64 therein. This table projects beyond the front of the device, as clearly shown in the drawings, in order to allow the body of the machine some clearance from the wall. Above the table 63" is a housing 65 which projects considerably beyond the end plates 22. Within the housing is a small carriage 66 having a cutting wheel 67 'ournaled in the lower portion thereof and a apted to ,cooperate with one edge of the table slot 64, to form shears for cutting the paper transversely. The slot 64 also acts as a guide or track for the carriage,,which is held in close contact therewith by means of a semi-elliptical spring 68 mounted within the top of the housing 65 and engaged by rollers 69 on the top of the carriage. The shifting of the carriage is accomplished by means of cords or chains 70, of equal length, attached to each end thereof and passing out of the ends of the housing over rollers 71. These cords depend a suitable distance and are provided at the ends with weighted balls-or handles 72. Since the cords 70 are of equal length, one handle will be higher than the other when the carriage is .at the end of its travel, and the operator will, therefore, be enabled so to tell at a glance which cord to ull in order to draw the carriage across t e device to sever the paper.

The rotation of thevarious rolls and cutters is effected by any suitable gearing opas t e 4.5 erated from a convenient point, such belt gearin shown in the drawings. It is however, 0 vious that chain or wheel gearin or a combination of the two, may be substituted. A large drive pulley 73 is mounted on an adjustable bracket 74. on the lower member 15 of the support, and is provided with a suitable handle 75. This pulley is connected by a belt 7 6 with a pulley 77 on the shaft of the upper feed roll 30.

Mounted on the same shaft as the pulley 7 7 are two other pulleys 78. From one ofthe pulleys 78, a crossed belt 79 runs to the pulley 80 on the drive shaft 38 of the paste roller 37, while from the other pulley 78 a belt 81 runs to the pulley 82 on the shaft 61 of the. upper discharge roll. This belt also passes over and drives thepulley 83 on the upper shaft 52 ofthe adjustable cutters.

All the feed rolls are preferably of rubber mounted on metal cores orshafts.

All the cutting devices comprise two coiiperating members which act like shears and, therefore, preclude any possibility of tearing the paper. Only one member of each pair of rolls or cutters is positively driven, the other member revolving by frictional contact with the driven member or moving paper.

In setting up the machine, the paste reservoir is first filled and the scraper adjusted according to the thickness of paste used. The paper roll 26 is then placed on the spindle 24 and inserted in themachine and the paper passed over the shaft 28, be

tween the shafts 52 and 52 over the guide 51 and between the feed rolls 30 and 30 The roll 49 is preferably removed and the paper drawnback over the paste roller 37 and the roll 49 replaced over the paper. The paper is then drawn forward and passed over the guide 62 between the discharge rolls 59 and 60, and over the cutting table. If, in the latter part of this operachine, it will be coated with paste as i passes over the roller 37, so that there will be only a very smallamount of waste caused by unpasted paper. This waste portion may be trimmed ofl. if desired by pulling the higher of the two handles 72, so as to draw the carriage 66 across the paper, the cutting wheel 67 therein cooperating with the table slot 64 to form shears which sever the paper and at the same time cut theends at exactly right angles with the side edges thereof. The device is now moved'up to the wall 84 to be papered and the support ex tended by turning the crank 20 until the paper handling device is raised to the correct height. The correct height may be ascertained by measuring 'the distance from the picture molding 85, cornice or ceiling to the top of the cutting table, which distance should equal the distance from the front edge of the table to the cutting slot, in order that when the paper lying horizontally on the table is severed and swung to a vertical position, it will exactly reach the picture molding 85. When the machine has been set as to height, the bracket 74 carrying the drive pulley 73 is adjusted to properly tension the belt 76. The driving pulley is now rotated to operate the paper handling mechanism which delivers the 'tion the, paper is drawn through the ma i trimmed and pasted paper, the paper being dam and heavy with paste does not curl but alls in a vertical line from the edge of the cuttingtable. When the lower end of the paper strip reaches the skirt board 86,

I to. sever the same.' The machine is moved to one side and the paper pressed into place Y in the usual manner. 'The next length of paper islowered in the same way until the pattern on the two strips matches, andis thensevered at the top as before. *When a door, window or corner, is reached, the adjustable cutters 53 and 55* are adjusted on their shafts 52'Qand 52' to cutJa strip of paper the required width., .In setting the cutters 53. and 55', th e distance ismeasured from the stationaryend trimmers 31 and 32,

the cutters being set as shown in Fig. 7. Otherwise the operationis the same. As the paper passes between the feed rolls :and 30, it also passes between the trimmers mounted on the ends of these rolls and-the edges trimmed perfectly smooth and parallel by the overlapping cut-tin edges of the cutters, as will be easily un erstood by aninspection of Figs. 5 and 7. The roller 37 revolves through the paste'inthe reservoir 36 and raises a constant fresh supply therefrom, the amount of which is gaged by the scraper 413 beforeitis deposited on the paper passing over. the roller. Wall paper is always rolled with the face or pattern side in and it will be'obvious from Fig. 3, that by taking the paper from the back of the roll 26, as shown, the reverse side will be in contact with the paste roller. By doubling the paper around the roll 49, it is discharged over the edge of the cutting table with the pasted side away from the machine and toward the-wall, so that after the paper roll is once inserted in the ma-' chine, it need not be touched by the operators hands at all, thus eliminating any danger of soiling. The trimming from the edgesof the paper will pass down through the space at the ends of the. scraper formed 38 when a different width of paper is used.

As the "scraper cannot be conveniently made in sections, a small bar 45 is adjustably mounted thereon so that it maybe slipped out to scrape the end of the roll when the portion 37 't-hereof is removed, as indicated in Fig. 4. I
