TED R. WYNN BY 19 7' TORNE Y5 United States Patent WALL FAPER HANGING APPARATUS Ted R. Wynn, Birmingham, Ala. Application November 12, 1953', Serial No. 391,465

12 Claims. c1. 216-6) This invention relates to wall paper hanging apparatus and is an improvement over thatv described and claimed in my co-pending. applications for patent, Serial No. 222,429 filed April 23., 1951, which matured into Patent No. 2,662,657 on December 15, 1953, and Serial No. 227,866 filed May 23, 1951, which matured into Patent No. 2,662,658 on- December 15, 1953 An object of my invention is to provide paper hanging apparatus embodying improved means for applyingv the paste to the paper whereby the paste is not pressed outwardly of the outer edges of the paper.

Another object of my invention is to provide paper hanging apparatus including improved means for steadying the same. against the surface to be papered and at the same time preventing the apparatus from pressing the paper against the surface to be papered.

A further object of my invention is to provide paper hanging apparatus embodying a paste container, an endless mesh belt mounted tor rotation with a portion thereof below the surface of the paste in the container and constructed to provide uniform tension without stretching or shrinking under various operating conditions.

A A further object of my invention is to provide means for applying uniform quantities of paste to the paper as it passes through the apparatus.

A further object of my invention is to provide improved means for trimming the paper together with means for adjusting the apparatus whereby it will accommodate paper of different widths.

A still further object of my invention is to provide apparatus of the character designated having handle means adapting tlie apparatus for use in various operat ing positions, such as applying the paper to. walls and ceilings of rooms or for use in applying paste to strips of paper. 4 Apparatus embodying features of my invention is illust'r'ated in the accompanying drawings forming a part of this application, in which:

Fig.1 is a front elevational view of the ap aratus, partly broken away and in section;

Fig. 2 is a sectional view taken generally along the line II-II of Fig. 1; I I

Fig. 3 is a fragmentary plan View of one end or the apparatus; and V c Fig. 4 is a plan view showing the handle member removed from the apparatus and drawn to a smaller scale.

Referring now to the drawings for a better understanding of my invention, I show a frame comprising side Walls and 11' spaced apart by a paste container 12. The paste container is substantially U-shaped as viewed in cross section and comprises vertically extendingwalls 13' and'14' and a curved bottom portion 16.

' The ends of. the U-shap'edpaste container are secured to the side walls 10 and 11, by any suitable me'ans' su'ch as welding; to form a fluid tight joint therewith. The portionoftheside walls 10 and 11 at the end ofthe paste container thus form thee'nd walls for the'paste con tainer'. j

The rear edge of the side walls 10 and 11 extends up 2 wardly and rearwardly to form arearwardly projecting portion 17. The upper edges of the side walls 10 and- 11 slope forwardly and downwardly as at 18- to form a curved upper edge.

Openings

19 and 21 are provided in the forward portion of the side walls 10 and 11 for receiving the ends of a rod 22 which is of a size v to fit within and rotatably support a roll of wall paper indicated at 23. The rod 22 is secured in place by means of nuts 22a. Slidably engaging the rod 22 adjacent opposite ends thereof are a pair of

disc members

24 and 26 having openings therein for receiving the rods 22. The openings are positioned on center, thus causingthe discs to engage a portion of the apparatus and be held against rotation in a manner to be described hereinafter Openings 27 and 28 are provided in theside walls-10 and 11 upwardly and inwardly of the rod 22 for receiving the ends of a guide rod 29, which is securedin place by means of nuts 29a. Extending between the side walls 10 and 11 and secured thereto by means of nuts 31 is a rod 32. Slidably engaging the rod 32 .is 3.. cylindrical member 33 having a longitudinally extending opening 34 therethrough. A substantial portion of the rod 32' adjacent each end thereof is threaded as at. 36. Positioned against the ends of the cylindrical member 33 and surrounding the rod 32, as shown in Fig. 2 are paper trimmers 37. The trii-nmers are preferably in the form of razor blades. Th'readedly engaging the rod 32 adjacent the trimmers 37 are disc-shaped spacer washers 38 which are locked in position by means of adjusting nuts 39. By positioning the trimmers outwardly of the spacer washers 38, the distance between the trimmers may be increased, thus permitting wider sheets of paper to be employed. While I show only two spacer washers 38, I contemplate employing the required number of such washers to accommodate the cylindrical member to the width of the paper used. The spacer washers 38 are of thesame diameter as the body of the cylindrical mem: ber 33, thus providing a continuous smooth surface for engaging the paper.

Extending between the side walls 10 and 11 inwardly of the cylindrical member 33 is a rod 41 which is held in place by means of nuts 42. The

rods

29 and 41 are positioned so as to engage the paper and hold it in contact with the cylindrical member 33, as shown in Fig. 2. The rod 41 is also in position for the upper end of the. trimmer to come in contact therewith as it tends to rotate in a counter-clockwise direction. The trimmer thus acts as a thrust washer to prevent unscrewing of the spacer washers 38 and nuts 39, thereby maintaining the trimmer in a fixed position.

Mounted for rotation between the side walls 10 and 11 above the paste container 12 and in

suitable hearing members

43 and 44 is a roller 46. Extending between the side walls 10 and 11 adjacent the bottom of the paste container 12 and within the confines thereof is a rod 47. Passing over the roller 46 and the rod 47 is an endless mesh belt 48 formed of a material which holds the required amount of paste to apply an even coatto the paper and does not stretch or shrink under various operating conditions. In actual practice, I find that a plastic mesh belt formed of polyvinylidene chlo'- ride, sold under the trade name Saran is satisfactory in every respect. In order for the belt' to hold the required amount of paste and to prevent telescoping of belt over itself and to prevent it from rolling up against the end walls of the apparatus, the plastic mesh belt should have from 25 to 45 ends or lineal threads per inch and from 15 to 3'5 ticks per inch on both the face and back thereof.

Mounted for rotation between the rearwardly project ing portions 17 of the side walls 10 and 11 on suitable bearing pin members 50 is a roller 49. The roller- 49 is cut away as at 51 adjacent the ends thereof to provide end portions of a diameter less than the central portion thereof. As shown in Fig. 3, the paper 23 projects outwardly of the enlarged central portion of the roller 49 and is spaced from the smaller diameter end portion thereof, thus preventing paste from being pressed outwardly of the outer edges of the paper and causing what is commonly called backlash. In order to accommodate the roller 49 to receive paper of different widths, the length of the enlarged diameter portion of the roller should be slightly less than the minimum width of the paper to be employed.

Suitable openings

52 and 53 are provided in the side walls and 11 for receiving a handle member 54. As shown in Fig. 4, the handle member is substantially U-shaped and is provided with inwardly projecting members 56 and 57 for pivotally engaging the

openings

52 and 53. The handle member 54 is provided with a detachable handle proper indicated at 53 which is secured to the base of the U-shaped member. Where it is desired to apply the paper to the ceiling of a room, a longer handle proper 58 is substituted for the short one shown in Fig. 4. Also, a flexible member, such as a cord 55, is attached to the handle member when it is desired to apply paper to a high wall. This is accomplished by lowering the apparatus to the floor thus permitting the operator to smooth the paper onto the wall as he moves down a ladder. Suitable brace members 59 and 61 conmeet the handle proper and the U-shaped member.

Mounted for rotation on the bearing pins 549 outwardly of the side walls 10 and 11 are a pair of rollers in the form of disc members 62 and 6?. As shown in Fig. 3, the

disc members

62 and 63 are larger in diameter than the enlarged diameter portion of the roller 49, thus spacing the roller 49 from the surface to be papered.

Extending between the side walls 1%) and 11 in position to contact the inner surface of the mesh belt 48 and remove excess paste therefrom as it rotates, is a rod 64 which is secured in place by nuts 66. Also, the upper portion of the vertically extending walls 13 and 14 of the paste container extend inwardly and downwardly at substantially 45 angles to form flanges 13a and 14a. The flange 13a bears against the belt 48 holding it in contact with the rod 64 thus efiecting a uniform coating of paste on the belt. The inwardly extending flanges 13a and 14a also prevent spillage of the paste.

From the foregoing description, the operation of my improved apparatus for hanging paper will be readily understood. To insert a roll of paper 23, the rod 22 is removed by removing one of the nuts 22a. One of the

disc members

24 or 26 is then removed from the rod 22 and the roll of paper inserted thereon. The disc member is replaced on the rod and the rod is inserted in the apparatus and held in place by means of the nut 22a. The roll of paper 23 and the

disc member

24 and 26 are moved longitudinally along the rod 22 until the paper is m proper alignment with the trimmers 37. The sheet of paper passes behind the guide rod 29, around the forward side of the cylindrical member 33 Where it comes in contact with the trimmers 37, thence under the guide rod 41 where it contacts the belt 48 and passes over the roller 46 therewith. After leaving the roller 46 the paper, having a uniform film of paste thereon, passes around and under the roller 49 thence upwardly of the apparatus where it is pressed against the surface to be papered by any suitable means, such as a brush. As the paper passes over the roller 49 the outer edges thereof are out of contact with the roller due to the fact that they are spaced from the cut-away portions 551. Accordingly, the paste is not pressed outwardly toward the outer edges of the paper, thus preventing the paste from getting on the outer edge of the paper.

As the paper is removed from the rod 22, the

eccentric disc members

24 and 26 contact the rod 29 thus limiting rotation thereof and locking the same in place. While I have shown two trimmers 37 for trimming the paper as it passes over the cylindrical member 33, it will be apparent that one trimmer may be employed where the wall paper is to be lapped. That is to say, the apparatus is adapted to trim one or both sides of the paper depending upon whether the edges of the paper are to lap or abut. The

rods

29 and 41 assure that the paper is held firmly against the cylindrical member 33 as it passes thereover thus providing a smooth and even cut by the trimmer.

When it is desired to run a wider sheet of paper through the apparatus, the spacer washers 38 and the trimmers are removed. The spacer members 38 are then positioned between the trimmer and the cylindrical member 33 thus spacing the trimmers further apart. Additional spacer washers 38 are employed where it is desired to position the trimmers in position to cut wider sheets of paper.

As the plastic mesh belt passes over the roller 46 and the rod 47, the rod 64 and the flange 13a contact the inner and outer surface thereof so as to prevent the paste from building up thereon, thereby controlling the amount of paste which adheres to the belt.

The

disc members

62 and 63 being larger in diameter than the roller 49 serve to steady the apparatus against the surface to be papered and prevent the roller 49 from pressing the paper against the surface in a manner to cause the paste to flow toward the outer edges thereof and cause backlash of paste.

When it is desired to apply the wall paper to a ceiling a longer handle member 58 is employed. The apparatus is then supported by a person who precedes a second person who smooths the paper onto the ceiling by any suitable means. Where the paper is to be applied to a high wall, the flexible member 55 is attached to the handle proper 58 and the apparatus is lowered to the floor, thus enabling the operator to use both hands in smoothing the paper onto the wall as he moves down a ladder.

My improved apparatus is also adapted for use as a pasting device and trimmer alone. This is particularly desirable when it is desired to apply paste to short strips of paper prior to placing them on the surface to be papered. Also, where a person does not have a second person to precede him in applying the paper to a ceiling, the paper may be trimmed and paste applied thereto before the paper is applied to the wall in the usual manner. Where the device is to be used for a trimming and pasting device only, the handle member 54 is clamped to a table or other suitable support. The paper is then pulled back over the top of the apparatus. The

rollers

49 and 46 are so positioned as to prevent the paper being removed from coming in contact with the paste as it is pulled across the rollers.

From the foregoing it will be seen that I have devised an improved apparatus for hanging wall paper. By providing improved means for applying uniform coatings of paste to the paper together with means preventing the paste from flowing toward the outer edges thereof, the paper is delivered to the surface to be papered in clean condition. Also, by providing an improved adjustable trimmer for my apparatus, the paper is automatically applied to the surface to be papered at the required width for either abutting or lapping the same. Furthermore, by providing a mesh belt which applies the required amount of paste to the paper and does not shrink, stretch or wrinkle under various operating conditions or telescope upon itself or parts of the apparatus, my apparatus operates substantially trouble free without clogging or applying excessive or insufficient amounts of paste.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the' spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
