Application'January 16, 1948; Serial No. 2,693 6Claims. (o1. 91- 51) This invention. comprisesnovel and useful improvements in a wall paper pasting machine and more specifically. pertains to a device for expeditiously and conveniently applying paste to pieces or rollsof wall. paper as desired.

The principal object of this invention is to provide an apparatus which will facilitate the convenient and eflicient applying of paste to pieces or rolls of wall paper.

A veryimportant feature of the invention consistsinproviding acombined paste receptacle and paste-applying apparatus for coating wall paper with paste.

A further featureoftheinvention consists in providing aframe pivoted within the receptacle upon which frameisjournalled a pasting roll which isimmersed throughout most of its circumference in..the paste contained within the receptacle; together with guide means carried by theframe below theupper surface of the paste rollfor depressing apiece or-sheet of wallpaper over theupper surfaceof the pasting roll whereby-thelatteris enabled to apply. paste to the wall paper duringsliding. movement of the paper over the roll; togetherwith. a support element carried by the frame above the pasting roll for supporting thepasted portion .of thepaperand preventing. the unpasted. surface-thereof from contacting the pasting roll.

Still further importantfeaturesof the invention reside in. the provision of a supporting frame which is .pivotedwithin the receptacle at one end thereof, whereby. the upper: end of the frame may be moved into or out .of the open end of the receptacle; together with fastening means for supporting and securing: the unpivoted end-{of the. frame in operative positionin the receptacle.

A still further feature of. the invention resides in the provision ofa pluralityof supporting. studs extending within the receptacle froma side wall thereof, for supportingrthe endof a piece ofpaper as the latter is threaded or applied to the pasting roll and guide grippers.

A final feature of the invention tolbe specifical- 1y. enumerated herein resides in the provision of a pasting apparatus, which :shall be compact, of light weight, easily applied to or removed from paste boardsand whiehlshall be particularly. for easy use by paper hangers in the customary methods of pasting, trimming and applyingwall paper.

These, together with .various ancillary. objects and features of the. invention which will later become apparent. ,as the following, description proceeds, are attained by this device, a preferred 2 embodiment of which is illustrated by way of example only. in the accompanying drawings, wherein:

Figure 1 is a perspective view, parts being broken away, of a preferredtembodiment of the invention;

Figure 2 is a top plan view .of the embodiment illustrated in Figure 1;

Figure 3 is avertical longitudinal sectional view through-the invention; and

Figure i is vertical transverse sectional view taken substantially by the, plane of the section 1i'rie-4.,4 of Figure Band 'illustrating'in dotted lines the position of a piece or sheet of wall paper in proper position in: the, apparatus for pasting.

Referring. now more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout thevarious view, the numeral, I0 designates. an open-ended casing H! of 'any suitable size, shape and material butpreferably of suificient dimensions to receive standard sizes of wall paper therein. The receptacle I0 is providedlwith'front and rear side walls 12 andv l4, together with end walls 16 and I8, the upper end of'the receptacle being open as above mentioned.

Extending, through and between the front and rear walls l2'and l4 and preferably adjacent one of theendwalls such as "5, is a pivot pin 20 preferably. positioned above the level of paste to be contained within the receptacle, for pivotally supporting thereon a frame containing the various partsof the pasting. apparatus. This pivot pin may. comprise a bolt or shaft extending entirely throughthe side walls l2 and M; but in some instances may consist merely of stub axles carried by the front andrear walls v and extending inwardly. therefrom. In any. event, the pin- 29 constitutes a hinge oraxle-about which an end member:- 24. of. the. frame is hinged for pivotal movement as .by journals or bracket 26.

The other endmember of the frame consists of an endplate. 28providedwitha horizontally and inwardly. disposedishoulderportion 30 which is adapted to.-selectively. engage and rest upon a support. Zlappropriately positioned in the receptacle.

Thissupport 22 may beof similar construction to that of the hinge pin-20, and is preferably providedasby means ofa pivot 32, witha fastener 34 of. any conventional design, adapted to be selectively. :moved into position. to .overlie and. rest upon the shouldered. portion 30, to thereby prevent upward movement-of the shoulder from the supporting pin 22., r

Although the

pins

20 and 22 have been shown as separately applied to and extending entirely through the walls I? and M of the receptacle 10, it will be readily understood that they may alternatively consist of integral inward extensions from these walls.

As shown best in Figures 1 and 4, the

end plates

24 and 28 are provided with aligned depending lugs or

portions

36 and 38 respectively, which preferably terminate just above the normal level of the paste within the receptacle, for a purpose to be later set forth.

As shown best in Figures 1, 3 and 4, a U-shaped frame consisting of upstanding legs 40 and M connected by a horizontally disposed back portion 42 is provided, the latter preferably being rigidly secured upon the bottom portion or bottom wall of the receptacle. The upper extremities of the legs 40 and 4-4 are provided with bifurcations 46 and v48 for a purpose to, be later set forth, these legs extending upwardly between the end plates '24 and 28 of the frame. The abovementioned depending lugs or

brackets

36 and 38 have secured therebetween parallel guide rods or

members

50 and 52 at opposite sides of the frame. These guide

rods

50 and 52 are preferably composed of bolts or the like having nuts 54 and 55 on the screw threaded extremities of one end thereof. By means of these nuts, the end members of the frame may be tightly and rigidly secured togetherto form a rigid assembly which is pivotal about the pin 29. Extending inwardly from the

leg members

40 and 44 of the U-shaped member, are a pair of aligned

stub axles

58 and 60 upon which parts is journalled a pasting roll 52 of any suitable material, which as shown in Figure e is preferably positioned with its lower surface justabove the bottom of the receptacle and its upper surface above the normal level of liquid within the receptacle. This roll is preferably provided with a plurality of longitudinally extending grooves 64 constituting means for conveying and retaining paste and applying the same to the surface of a paper with which the roll comes in contact as set forth hereinafter.

Rigidly secured between the upper ends of the

end plates

24 and 28, is a longitudinally and centrally disposed support rod 66 which is adapted to be received within the

bifurcations

46 and 48 when the frame is in its lowered position as shown in Figure 3. This support rod or element 66 thus serves to assist in properly positioning the frame when in its lowered position and ready for operation, and serves a further purpose as set forth hereinafter. I I I I I As shown best in Figure 2, aplurality of longitudinal spaced studs 68 I are screw threaded through the rear wall I4 into the interior of the receptacle at a suitable position above the level of the liquid therein as shown in Figure 4. These studs constitute, a support means for a sheet or roll of paper as the latter is threaded into and positioned in the device for pasting thereby.

The operation of the apparatus is as follows:

The frame, including the three

members

50, 52 and 66, is raised by pivotal movement of the frame about the hinging pin 20, whereby the other end of the frame '28 is elevated above the support rod 22' and above the open'portion of the receptacle ID. a sheet or the end of the roll of paper as indicated in dotted lines in Figure 4, is now applied to the device. For this purpose, the end of the paper is drawn over the side l2 beneath the two raised guide grippers 50 and" 52, and above the upper surface of the pasting roll 62, thence upwardly as indicated by the arrow and over the upper support member 66, and then drawn outwardly over the front wall l2. It will be noted as shown in Figure 4, that the paper is disposed with a surface to receive the paste downwardly on the lower plate, and upwardly on the upper plate, whereby the paste portion is prevented from contacting the design surface of the paper. When the paper has been disposed beneath the two guide grippers 5B and 52, the end of the same is adapted to rest upon the support stud 88, whereupon the frame is lowered into the receptacle with the support rod 8.6 received in the

bifurcations

46 and 48. This depresses slightly the paper about the upper surface of the pasting roll 62, in the position illustrated in Figure 4.

The end of the paper is then grasped by inserting the fingers of the operator between the studs 68 and the paper drawn about the guide member 50 and over the supporting rod 66 as above mentioned. It will thus be seen that the supporting studs prevent the end of the paper from dropping down into the paste when the paper is initially inserted in the device, and it is desired to use the end of the paper and to apply paste thereto.

Since in customary operation the paperhanger cuts off a piece of paper the exact size which it is desired to use, it is obvious that there can be no waste permitted when drawing this paper through the machine for applying paste thereto. In the present apparatus it is possible to employ quite small pieces of paper, since as the end of the paper is drawn across the pasting roll in initially inserting the paper in the device, the same becomes coated with paste and then rests upon the supporting stud while the

guide rods

50 and 52 are lowered into their operative position. The supporting rod (it not only serves the purpose of lending rigidity to the frame, but also serves to prevent undesirable contact of the pasted upper fold of the paper with other objects, and also prevents the danger of soiling the unpasted side of the wallpaper by accidental contact with the pasting roll.

From the foregoing the manner of constructing and operating the device and the advantages arising therefrom .will be readily understood. Since numerous modifications and changes will readily occur to those skilled in the art after a consideration of the foregoing specification and attached drawings, it is not intended to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents maybe resorted to falling within the scope of the appended claims.
