The present invention 'relates to improvements in paper hanging machines and has for an object to provide an improved machine of this nature which will more efficiently and 5 economically hang and apply the paper to both Walls and ceilings.

Another object of the invention resides in providing an improved paper hanging machine which will mechanically and successively carry l out the operations of conveying the paper to the place of application, whether it be upon the wall or the ceiling, holding ythe paper in its position of application, and brushing or pressing the paper firmly upon the wall or ceiling whereby to finally l apply the same.

A further object of the invention is to provide an improved paper lhanging machine in which the operations described in theforegoing paragraph may be manually controlled with a minimum of effort and with a high degree of accuracy.

A still further object of the invention is to provide an improved paper hanging machine in which the parts will be grouped into relatively small compass for ease in transportation and to occupy confined spaces, the parts being so coordinated and relatively arranged that the same may be operated centrally from a power unit of small capacity. v

A still further object of the invention is to provide for a magazine roll of the wall paper upon the machine in positioning relatively to other agencies whereby the paper may be trimmed at its edges if desired, cut off into appropriate lengths and applied with adhesive, all prior to being transferred to the conveying and applicator appliances.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, andwill be more particularly pointed out in the claims appended hereto.

Referring more particularly to the drawings, I4 designates a platform mounted upon casters or rollers I5 and carrying in common the various devices which contribute to this machine. 25

The paper or rather the roll of paper is indicated at I6, the same being detachably carried in supports Il erected at a suitable point upon the platform I4 whereby the paper uncoiling from such roll I6 may be readily directed through 30 the trimmer knives I8 which are appropriately journaled or mounted in a frame or suitable support I9. These trimmer knives act on the side edges of the paper, they being spaced apart in pairs as indicated in Figure 8. 35

From the trimmer knives the paper passes to the transverse shearing knife 20 also shown in Figures 1 and 8, such knife being mounted in .a supporting frame 2l also carried by the platform I4. 40

On the platform and adjacent the shearing knife 20 is the paste applying device carried by a frame or supporting structure 22 and consisting generally of two opposed rollers 23 and 24, the latter of which rolls around in a trough 25 45 containing a body of paper hangers paste.

These various devices, or such of them as are driven, for instance the rolls 23 and 24 and the paper roll I6, may be operated from the same source of power, which in this instance, for pur- 5 poses of example, may be an electric motor 26 also mounted upon the platform I4 and having a belt connection 2l to a main power shaft 28. As shown in Figures 1 and 2 the shaft 28 has a belt connection 29 to the shaft 30 of the lower 55 roller 24, and the latter shaft 30 has a belt connection 3l to the roller I6 or its shaft 32.

The main shaft 28 is journaled in uprights 33 mounted on the platform I4 and braced by the diagonal braces 34 or other suitable form of braces.

The shaft 28 carries at its outer end portions bevel gear wheels 35.

As shown in Figure 1 three bevel pinions 36, 31 and 38 are disposed in mesh with the gear wheel 35 at-one side of the apparatus. These bevel pinions 36, 31 and 38 are upon the convergent end respectively of shafts 39, 4|] and 4l. These shafts converge towards the shaft 28 as a center. The shafts are journaled in appropriate bearings on the uprights 33 and on suppo-rting arms 42 and 43 which are mounted on the up'- rights and diverge upwardly therefrom.

The shafts 39, 40 and 4l at one side of the machine are for the purpose of sliding the paper carrying and the brush arms as hereinafter described. On the opposite side of the machine are three similar shafts 44 for accomplishing the rotary movement of the arms. The shafts 44 have bevel pinions 45 which mesh with the bevel gear wheel 35 at that side of the machine.

Three arms are ordinarily used in the machine, these arms being designated broadly A, B and C. Of these arms, two namely A and C, are paper carrying arms having clips at their outer ends for grasping the edge of the wallpaper; while the intermediate arm B is a brush arm and carriesI a brush at its outer end. The arms A and C are substantially identical except for their position, the same being carried by the divergent arms 4l and 42. A description of one of these armsA will suflice for both. Figures 3, 4 and 5 show one such arm which we will call the arm C. At the left end of Figure 3 there is' shown one of the shafts 44 extending up through a gear box 46. Within the gear box are opposed bevel p-inions 41 and 48 in mesh at diametrically opposite points with a bevel gear wheel 49 fast uponv one end of a shaft 50. The bevel pinions 4 1 and 48 are loose upon the shaft 44 and are selectively locked to rotate with the shaft 44 by means of a sliding collar 5I having pins 52 for interlocking sockets 53 in the. bevel pinions 41 and 48. A lever or hand piece 54 serves to throw the slidingk collar I toward and from the pinions 41 and 48.. When the Vlever 54 is thrown to one side the pin 52 at that side. will enter socket 53 of the adjacent bevel pinion 4-1l or 48 whereby the shaft 50 will be driven in one direction. By reversing the movement of the lever 54 the other bevel pinion will be connected with the drive shaft 44 and the shaft 50 will beturned in the opposite sense or direction.

The shaft 50 has rounded trunnionsl at its ends for the purposes of its mounting in the supports of the machine but throughout the majo-r portion of its length it is preferably substantially square as shown in cross-section in Figurel with its upper side open for a purpose later described. Within the hollow square portion of shaft 50 is rotatably mounted a broad gear wheel 55. This broad gea-r wheell 55 extends through the right hand end of shaft 58, as shown in Figure 3, and enters a gear box 56 similarto the gear box at the left hand end of the shaft. This gear box contains a bevel pinion 51 fast on broad gear wheel 55. Bevel pinion 51 is adapted to be driven in one` or the other direction accordingly as a shifting lever 58 isl thrown in the one or theother direction. This shifting lever is, connected. with a: sliding collar in the gear box, whichcollar is driven by a shaft 4I and thereby drives the bevel pinions 60 and 6I whenever the pins 62 of the collar engage the sockets 83 ofthe bevel pinions 60 or 6I. Thus the rotation of the broad gear wheel 55 is quite independent of the rotation of shaft 50 in which it is mounted.

Slidably mounted on the square part of shaft 58 is a square sleeve 64. This square sleeve will not rotate on the shaft 58 or relatively to the shaft 50. The square sleeve '64 forms part of a casing of which a round sleeve 65 also forms a part. rl'he sleeves may be of any desired crosssectional form, but the square cross-section of thel sleeve 64 and shaft 50 is convenient as causing rotation of the sleeve with the shaft but allowing the sleeve 64 to be moved axially along the shaft.

The upper sleeve 65 carries slidably therein the arm C. As a matter of fact the arm C is preferably made in two sections 66 and 61 of which the outer section 61 slides telescopically within the inner larger section 66. The outer section carries the clip 68 having movable jaws 69 kept closed by the spring which is associated with the pivot about which the two jaws 69 are adaptedto move in opening and closing. One of the `jaws has a hood 12 to which a cord might be axed which cord extends down to the platform I-4 for the purpose of pulling upon the string and upon the jaws 69 when it is desired to release the paper when the clip is in a high position out of reach of the paper hanger. Y

The arm section 66v isI provided with teeth 13 meshing with a pinion 14 carried by the sleeves. This pinion meshes with the teeth of the broad gear wheel 55. As indicated in Figure 3, the teeth of pinion 14 will slide along the teeth of the broad gear wheel 55 when the sleeve 65- is slid axially along shaft 58. Thus the broad gear wheel 55 will drive the pinion 14 no matter what the position of sleeve 64 is upon shaft 5D.

In a similar way another pinion carried` by the sleeves at the side thereof meshes with the teeth of broad gear Wheel 55 and with the teeth of a rack barr16- carried by the outer arm section 61 and extending alongside the roundupper sleeve 65. Thev ratio of gear wheel 14 and 15 is preferably different. y

It will be understood that the rotation of shaft 58 in either direction as controlled by the shifting lever 54 will cause the arm C to rotate withshaft 50 in one or the other direction, and the arm C may be slid through the upper sleeve 65 in one or the other direction by operation of the opposite shifting lever 58. Thisr shifting lever 58- causes the broad pinion 55 to rotate in one or the other direction. The broad gear wheel imparts similar motion to pinions 1-4 and 15. When pinion 14- is driven clock-wise in Figure 5 the arm 66 is moved to the right and so moving the outer arm section 61 is' telescoped with-in the arm section 66, the gear ratio being such that the rack bar 16 is moved more rapidly than arm section 66. Thus the clip 68 may be moved towardor from the wall or vthev ceiling.k It may be pointed toward the wall or ceiling or to an appropriate place rthereon by rotation of the shaft 50.

Referring morefparticularly to Figures 6f and 7, a somewhat similar construction is shown with reference to the brush arm B.

The brush itself is indicated at 1.1 and it isl carriedwithin the outermost arm portion 80'having the elongated slots 9| as shown. This arm portion 801 is mounted Within the armsection 18 and is attached thereto by a pin 9.2' passing clockwise direction.

through'the slotsv 9| which permits movement of the outermost arm inwardly and outwardly relative to the arm section 18. A coil spring 93 is housed within the arm section 18 having the inner end of the spring abut the plate or member 94 whichis secured tothe arm section 18, and having the outer end of the spring contact with the inner end of the outermost arm portion 80.

Y This coil spring 93 is normally expanded when the pin 92 engages the ends of the slots 9| in the outermost arm 80 as shown in Figure 7, but when pressure is placed upon the outside of the brush 11 the slots 9| permit the outermost arm to move rinwardly upon the pin and compress the coil spring. One end'of a flexible strip 95 of steel tape is attached to the outer end of the coil spring 93, and its other end extends through the slot 95 in the arm section 18 to a'greater or lesser length according to the contraction or expansion of the coil spring 93 and serves as a signal for the operator regarding the amount of pressure exerted upon said spring.

A rack bar 8l is attached at one end to the arm section 18 by a rivet 91 and its other end extends rearwardly to mesh with a pinion 82. The pinion in turn meshes with a broad gear wheel 83 which allows the pinion 82 to be moved axially along the broad gear wheel 83. The broad gear wheel 83 is journaled to rotate within a square or other form of hollow shaft 84 having an open side through which the pinion 82 may engage the teeth of the broad gear wheel 83. A square or other formed sleeve 85 is slidable on shaft 84 but rotates with the shaft to adjust the position of the sleeve along the shaft.

The Ysleeve 85 carries an upper sleeve 86 which may also be square or of other desired form and which slidably receives the arm section 19. The shaft 84 is journaled in the uprights 33 and has round trunnion end portions for this purpose. The shaft 84 is rotated from the shaft 44 by means of the gearing in the gear box 81 at one 'end of the shaft. As this gearin-g has already been described in connection with Figure 3 it is thought that no further description of the same is necessary. A gear shift lever 88 controls the direction of rotation of shaft 84.

yAt the right hand end of shaft 84 is another gear box 89 containing gear shift mechanism in all respects identical with the gear shift mechanism shown at the right hand end of Figure 3 so that no further description thereof is needed. This gear shift mechanism provides for rotating the broad gear wheel 83 in one or the other direction accordingly as the lever 98 is shifted to one or the other side.

In the operation of the device, the upper paper carrying arm C is rst shifted to the position shown in Figure 9. This is accomplished by throwing the lever 58 shown'at the right hand of Figure 3 in one direction whereby to cause pinion 14 in Figure 5 to rotate in a clock-wise direction. This is attended by the arm C moving to the right in Figure 4. As large section 65 moves to the right, small outer section 61 will be moved faster in the same direction and thus caused to enter the tube or large section 66. When the condition of the parts as shown in Figure 9 is arrived at, the lever 58 is thrown into neutral discontinuing further rotational movement of the broad gear wheel 55.

It is then desired to move the arm C to the position shown in Figure 10. This is accomplished lay-rotating the shaft .50 in a counter- This is accomplished by throwing the lever '54 at the left hand end of Figure 3 in the appropriate direction. When the parts have arrived in the position shown in Figure 10, the lever 54 is shifted back to neutral. Then the opposite lever 58 may be shifted so as to project the clip 68 downwardly toward the paste applying rollers 23 and 24 so as to receive the end of the paper roll therefrom, the jaws 69 being open for this purpose. To accomplish this downward projection of the clip 68, the lever 58 is thrown in the direction opposite to that first described in order to cause the pins to rotate in an opposite sense and therefore project the arm sections 66 and 61. When an appropriate downward point has been reached the lever 58 is again thrown into neutral. After the paper has been rmly grasped by the clip 68, the lever 58 is again so shifted as to cause the movement of the arm upwardly until the sections 66 and 61 are nally collapsed; whereupon the lever 58 is again shifted into neutral, and the opposite lever 54 is so shifted as to cause the shaft 50 to rotate the arm back from the position shown in Figure 10 to that shown in Figure 9.

As the paper is pulled out it may be trimmed along its edges by the trimmer knives I8. When a suitable length for covering a wall or ceiling is drawn out from the roll of paper I6, the knife 28 may be brought down to Sever the paper stripped from the roll. The arm C may then carry the upper edge portion of the paper out to a high point upon the wall as to the angle between the ceiling and wall which position is indicatedin Figure 12. During this time the brush arm B may be offset, as indicated in Figure 2, to one side of the path of movement of the paper up to and against the wall; but after the paper is in a suspended position against the wall, being held thereto by the arm C as indicated in Figure 12, the brush arm B is shifted axially along its shaft 84 until it is in position to wipe up and down against the paper upon the wall. To cause the brush 11 to advance against the paper, the lever 90 at the right of Figure 6 is rst thrown in an appropriate direction to cause the gear wheel 82 to move in an anticlock-wise direction. When the brush has been moved up against the suspended paper strip, the brush shaft 84 is rotated as by throwing the lever 88 at the left end of Figure 6 in the appropriate directi-on. The brush 11 thereupon wipes down the wall and presses the paper firmly thereagainst, smoothing out the paper during its descent. As the brush will tend to travel in a true arc about the shaft 84 as a center, and the at vertical wall precludes any arcuate movement at the outer end of the brush end B, the brush is permitted to move relatively by operating the lever 98 to cause the reverse gear to actuate. This action will permit a slow and gradual shortening of the arm B without affecting the continued downwardly swinging movement of the arm. The positioning of the coil spring 80 as shown and explained will at all times keep the brush y11 up to its work and maintain the necessary pressure of the brush 11 upon the paper.

On referring to Figure 12, it is here diagrammatically shown how both arms A and C hold a strip of paper at opposite ends up against the ceiling. This strip of paper has been received from the paste applying rolls and it is ready to be rmly pressed against the ceiling by action of the brush arm B. Inasmuch as this brush arm B occupies anintermedate position between the paper carembodiment of this invention without departing and meansfor sliding the sections with respect ryingl arms A and C, the brushy arm B may beA swung back` and forth by the selective engagementk of the lever 88 at the left endof; Figure 6,r

while the arms A, B and C are shown as composed of twosections they may be composedof any desirednumber of sections.

A suitable measuring d-evice 98, as shown in Figures l and 8 is readily attached to the support I9A for the purpose of measuring the desired length of Wall paper as the same is unwound from the roll it during the operation of thedevice. Arms A and C are constructedto carry in their outermost sections the clips 68 having the movable jaws 6,9 which can` be varied in shape or design as Well as other types of clips for the purpose of more efficiently working on borders and in corners.
