PASTING APPARATUS.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed July 12, 1915. Serial No. 39,438.

To all whom it may concern:

Be it known that I, WARD B. DUNLAP, a citizen of the United States, residing at Delaware, in the county of Nowata and State of Oklahoma, have invented certain new and useful Improvements in Pasting Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved pasting apparatus and has for its primary object to provide a machine for this purpose which is primarily designed for applying paste to wall paper whereby the papering of walls may be greatly expedited.

It is one of the more particular objects of the invention to provide an improved mounting and construction of paste container and means arranged therein for uniformly applying the paste to the paper.

The invention has for an additional ob ject to provide means for removing the surplus paste from the paper and an improved mounting for a rotary cutter knife, whereby the paper drawn from the roll may be subsequently cut in sections of the desired length.

. The invention has for still another object to provide means for trimming thepaper, and operating said trimming mechanism either simultaneously with the pasting device or independently thereof.

It is a further general object of my invention to improve and simplify the construction of paste applying machines of Y the above character, whereby the same may be very easily and quickly assembled and arranged in condition for use, the machine, as a whole, consisting of comparatively few parts which are positive and reliable in their operation.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a paste applying machine constructed in accordance with the preferred embodiment of my invention; Fig. 2 is a front elevation thereof;

- Fig. 3 is a longitudinal section; and Fig. 4

is a detail perspective view of the cut off knife and the support therefor.

Referring in detail to the drawing, 5 designates two parallel side walls which are connected together and held in spaced relation by'a plurality of transversely extending rods or bolts 6. The side walls 5 are also provided at their opposite ends with the spaced upper and lower longitudinally projecting arms 8. Each side wall is further provided with a central longitudinally extending slot 9 which opens at its outer end between the spaced arms 8. The container or receptacle for the paste, shown at 10, is preferably cylindrical in form and arranged between the spaced side Walls .5. This conbrush is provided at itsopposite ends with.

trunnions 16 which are journaled in bearing plates 17 arranged upon the outer faces of the plates 5 and extending vertically across the'slots 9 said faces. The opposite ends of the caring plates 17 are sooured to the plates 5 by suitable screws 18. It will be understood that the trunnions 16 on the ends of the rotary brush project outwardly through the slots 12 in the end walls of the container 10, and one of these trunnions has a large gear wheel 19 fixed thereon, the extremity of said trunnion beingof rectangular form to receive the socket of a suitable crank 20, whereby the brush may be manually rotated. The bristles of the brush 15 project outwardly through the opening 11 in the side wall of the container, and at the upper side of this opening opposite to the tubular bead 13, a guard plate 21 is hinged, as at 22, upon the container wall. Additional vertical bearing plates 23 are also secured upon the outer faces of the arms 8 on each of the side plates 5, and in these bearing bars the trunnions 24: on the ends of the lower roller 25, are journaled. One of these trunnions has a gear wheel 26 fixed thereon which meshes with a power transmission gear 26""journaled upon a stub shaft 26 secured in the side plate 5, said transmission gear also meshing with the gear 19. Thus, the rotary brush and the roller 25 are rotated in the same direction.

has a similar slot 29 formed therein.

Through theseslots, the trunnions 30 on the ends of the upper roller 31 are disposed. In the upper end of each of the arms 27, a. vertical rod 32 is slidably engaged, the lower end of said rod being provided with the bearing block 33 for engagement upon one of the roller trunnions 30. A spring 34 is arranged upon said rod between the upper end of the arm 27 and said bearing block. Upon the rod 32, a nut 35 is threaded, and by adjusting this nut, the tension of the spring 34 may be regulated, as desired.

To each of the vertical bearing bars 23, and centrally thereof, a forwardly projecting arm 36 is secured. The forward end of each of these arms 36 is provided with a socket to receive one end of a transversely disposed bar ,37. A longitudinally extend;

ing kerf 38 is cut in the upper face of this bar and a metal plate 39 is also countersunk in the upper face of the bar at the outer edge of the kerf 38. A wire rod 40.

extends in longitudinal parallel relation to the bar 37 above the same and has itsends angularly bent, as at 41, and the extremities thereof turned inwardly and en aged through openings in the arms 36 and tting into sockets formed in the ends of the bar 37.

42 designates a rotary steel cutting disk adapted to travel in the kerf 38. This cutting disk is journaled upon an axle pin 43 fixed in the lower bifurcated end of a vertically disposed bar 44. This bar is formed with an opening through which the rod 40 is loosely engaged and said bar may be readily shifted longitudinally upon the rod and the cutting disk 42-moved along the guide kerf 38.

When the parts are assembled or arranged 'in position between the side plates 5, the curved guard plate 21, which is hinged upon a wall of the paste container 10,.ex-

tends over the upper roller 31 substantially in concentric-relation thereto, suitable stop lugs or supports 45 being fixed to the inner faces of the side walls 5 upon which this guard plate is adapted to rest.

In conjunction with my improved pasting apparatus, I provide means for trimming the paperas it is drawn from the roll. To this end, uprights or standards 46 are securedto thev rear ends of the side walls 5 and between the same the two rollers 47 and 48 are rotatably mounted. The bearings for the lower roller 48 are stationary while the upper roller 47 is vertically movable between the standards and is yieldingly held against such vertical movement by the springs 49 which are mounted in a similar manner to the springs 34 of the roller31, above referred to. Each of the rollersi47 and 48 has a cutting ring or annulus 50 fixed thereto adjacent one of its ends, and

the cutting ring on one roller operates in the annular groove 51 in the periphery of the upper roller and cooperates with the cutting ringon the lower roller to produce a shear cut of the paper as it is drawn between the rollers. The upper edges of the spaced walls 5 are connected by parallel barsor ribs 52, and these ribs are received in notches, indicated at 54, in the lower faces of the cleats 53. These cleats are connected by spaced slats 55 upon the opposite ends of which the bearing members 56 are secured. In these members, the gudgeons of a paper roll P are journaled. In the upper ends of the uprights 46, the ends of a rectangular roller '57 are removably mounted, and upon this roller the trimmed paper is adapted to be wound when the pasting mechanism is not being used. Upon one end of the shaft of the roller 57 a belt wheel 58 is fixed, and a similar wheel indicated at 59 is also secured upon one end of the shaft of Qhe lower roller 48. This wheel isadapted-to be connected bv a crossed driving belt 60 to the belt wheel 61 which is fixed upon one end of the brush shaft. When it is desired to operate the trimming mechanism independently of the pasting device, the wheels 58 and 59 are connected by a power transmission belt 62. One end of the shaft of the lower roller 48 is square so that the crank 15 may be readily applied thereto.

the paper from the roll P is drawn between the trimming knives 51 on the rollers 47 and 48 and then extended forwardly beneath the container 10,'as clearly shown in Fig. 3, and

upwardly over the lower roller 25 so that the paper will be engaged by the brush 15. The bristles of the brush projecting through the opening 11 in the container wall willcontact with the paper sheet. It will be understood that the crank 20, as it is turned, rotates the pasting brush and rotation is also transmit ted through the medium of the belt 60 to the roller 48. The peripheries of the rollers 47 and 48 are engaged so that the paper is fed thereby to the machine and, at the same time, is cut or trimmed by the knives 51. The spring pressed upper roller 31 bears upon the paper sheet an d operates in conjunction with the lower relatively stationary roller 25 to remove the surplus paste from the paper. The curved guard plate 22 prevents this paste being carried upon the 'periphery of the roller 31 and thrown for per face of-the bar 3 42 on the rod 40, saiddisk cooperating with the edge of the metal late 38 and the upg to cleanly cut the paper. When it isno longer desired to use the machine, the brush 15 is removed so that the paste will not dry upon the brush bristles and render the same stifi and unfit for subsequent use. This removal is readily accomplished by simply detaching the bearing plates 17 from the side walls 5 of the machine and then shifting said roller forwardly through the opening 11 in the wall of the container 10. It is, of course, understood that the rollers 25 and 31 must first be removed from the side plates of the machine before it is possible to remove the brush. If desired, the side plates 5 may also be disconnected, and the entire machine very compactly arranged for convenience in transporting the same from place to place. The apparatus as a whole is positive and reliable in its operation and provides Very convenient and serviceable means for facilitating the application of paste to wall paper. It is, of course, understood that the brush, as well as the rollers 25 and 31, will be of somewhat greater length than the width of the wall paper, as this width, after the paper has been trimmed, will vary to a greater or less extent. It will also be noted that, while I have shown and described the preferred construction and arrangement of the several elements of my invention, the device is susceptible of considerable modification therein and I, therefore, reserve the pzivilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire toclaim and secure by Letters Patent is 1 1. A paper pasting machine including a paste container vhaving a longitudinal openin a rotary brush mounted within said contalner, the bristles of the brush projecting outwardly through said opening, and means arranged adjacent to said opening exteriorly of the container to positively pull a paper sheet over the exterior surface of the container wall and past the opening therein for contact with the bristles of the rotary brush.

2. A paper pasting machine including a paste container having a longitudinal openmg in its wall, a rotary brush mounted within the container, the bristles of said brush extending through said slot, paper guiding and feeding means arranged contiguous to said slot exteriorly of the container and adapted to draw a paper sheet around the base portion of the container in contact with the wall thereof, and past the slot in the container whereby paste is applied thereon by the bristles of the brush, and guard means on the container wall adapted to be positioned with respect to said guiding and feeding means.

3. A paper pasting machine including spaced side plates, a, paste container mounted between said side plates having a longitudinally extending opening and slots in its end walls communicating with said opening, a rotary brush removably mounted within the container, upper and lower rollers mounted contiguous to the longitudinal opening .in the con-tainer, said roller being vertically movable, a guard plate arranged upon the container wall at one side of said longitudinal opening, a paper roll support,

the paper being extended from the roll between said rollers, said guard plate extending forwardly over the vertically movable roller, and gearing for positively rotating the brush and said lower roller.

4. A paper pasting machine including spaced parallel side plates, a cylindrical paste container having a longitudinal opening in its wall and a tubular head at one edge of said opening, a fastening -rod extending through said bead and the side plates, a guard plate hinged upon the wall of the container at the other edge of said opening, a rotary brush mounted within the container, the bristles of the brush projecting through said opening, upper and lower rollers mounted between the side plates forwardly of the container and contiguous to the opening therein, said guard plate projecting forwardly over the upper roller, the paper extending beneath the container and upwardly and forwardly between said rollers, and gearing positively rotating the brush and the lower roller.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
