MACHINE ron rns'rrne WALL-PAPER.

Specification of Letters'Patent.

Patented Mar. 26, 19 18.

Application filed. February 28, 1916. Serial No. 80,929.

'To all whom it may concern:

Be it known that I, WVILLIAM J. DUNN, a subject of the King of Great Britain, and resident of the city of Mont-real, Froviuce of Quebec, and Dominion of (-Janada, have invented certain new and useful Improvements in Machines for Pasting VVall-Paper, of which the following is a specification.

The present invention relates to portions of a machine of the class described, which machine in character is similar to that shown in Patent No. 1,131,685, granted March 16, 1915, to Dunn and Taylor, and entitled Wall-paper pasting and trimming apparatus.

One'object of the invention is to provide a knurled roller for thepurposeof evenly spreading a paste over the back of the paper and crowding the surplus paste to the side edge of the paper, where it can be removed.

A. further object of the invention is to make these knurled rollers in section, so that they can be adjusted to different widths of paper.

A further object of the invention is to adjust the knurled roller with respect to the periphery of the paper so as to vary the thickness of paste on the surface thereof.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings:

Figure 1 is a plan view showing a portion of a pasting and trimming machine with the roller of the present invention in operative position;

Fig. 2, a vertical section through a portion of the machine, and showing the said roller; Fig. 3, a detail showing a side view of the roller and its mounting; and

Fig. 4:, a detail showing how the roller is constructed to enable sections to be added thereto or detached therefrom.

The roller is carried by a frame 5 of suitable construction, in which frame is mounted a paste distributing roller 6, which applies paste to the back surface of a strip of paper 7 coming from a roll 8. The foregoing mechanism may be of any suitable construction and will not be described in detail.

After leaving the paste roll 6, the paper passes over a roll 9, and above this roll 9 is a knurled distributing roller 10. The distributing roller is carried at each end by an arm 11 pivotally mounted upon a shaft 12*. of the distributing roller 10 are removably mounted in the arms to permit an easy and quick removal therefrom if desired. j

The distributing roller 10 is composed of end sections 12 of reduced diameter, which are threaded at their inner ends as at 13 (see Fig. 1). The central portion 14 of the roller is of knurled formation. When it is desired to make the roller of greater length than in Fig. 1, supplemental knurled sleeves 15 are slid over the end of the reduced portion 12 of the roll, and the supplemental sleeves are interiorly threaded to mesh with the threaded portion 13 of the roll, and when they are aflixed in position as in Fig, 4, obviously the roll is increased an amount in length equal to the length of the said supplemental sleeves 15. Thus, by attaching or removing these sleeves, the length of the roller can be adjusted to conform to different widths of the paper.

Owing to the fact that paper will vary in thickness, and that upon some kinds of paper it is desired to place a different thickness of paste than on others, the distributing roll 10 is formed so as to be capable of adjustment with respect to the surface of the paper passing therebeneath. To accomplish this, I provide thumb screws 16 threaded through the arms 11, bearing against the frame of the machine (see Fig. 3) A spring 17 is provided, normally holding the arms 11 down. It is obvious that by manipulation of the finger-piece 16, the height of the roller can be adjusted as desired.

I claim:

1. In a machine of the class described, the combination of a frame, a holder for a roll of paper carried by the frame, means for applying a layer of paste to one side of the paper, a paste distributing roller having a grooved peripheral face, means for adjusting the height of said distributing roller above the pasted surface of the paper, sub stantially as described.

2. In a machine of the class described, the combination of a frame, a holder for aroll of paper carried by the frame, means for applying a layer of paste to one side of the paper, a paste distributing roller having a grooved peripheral face, means permitting a changing of the length of said distributing roller to accommodate different widths of paper, substantially as described.

3. In a machine of the class described, the combination of a frame, a holder for a roll of paper carried by the frame, means for applying a layer of paste to one side of the paper, a paste distributing roller having a grooved peripheral face, a pair of swinging arms carrying the distributing roller and pivotally mounted on the frame, means for raising and lowering the free ends of the arms to adjust the heights of the distributing roller With respect to the pasted surface of the paper, substantially as described.

4. In a machine of the class described, the combination of a frame, a holder for a. roll of paper carried by the frame, means for applying a layer of paste to one side of the paper, a paste distributing roller having a grooved peripheral face, means for adpisting the height Of said distributing roller above the surface of the paper, means permitting a change in the length of said d1s tributing roller to accommodate different Widths of paper, substantially as described.

5. In a machine of the class described, the

combination of a frame, a holder for a roll of paper carried by. the frame, means for applying a layer of paste to one side of the paper, a paste distributing roller havin a grooved peripheral face, a shaft on Which said roller is mounted, a detachable end sec-; tion forming a nortionof said roller and adapted to be detached from the body of the roller and moved away from said body along the shaft to vary the width of the roller, substantially as described.

6. In a machine ofthe class described, the combination of a frame, a holder for a roll of paper carried by the frame, means for applying a layer of paste to one side of the paper, a paste distributing roller having a grooved peripheral face, a portion of said roller being detachable from the remainder and adapted to be moved away from said remainder to varv the length of said roller, substantially as described.
