4 Claims. (o1.-;11s 24s) This invention comprisesnovel and usefulim- :provements in-a wallpaper pasting machine, more specifically pertains to a device for expeditiously and conveniently applying paste to pieces or rolls of wallpaper as desired, and constitutes an improvement and a continuation-impart of my copending application, SerialNo. 2,693, filed January 16, 1948, and now matured into Patent No. 2,512,221, issued June 20, 1950. 7 v

. r The principal object of this, invention is to pro- ..videan improved wallpaper pasting machine of "the character and general type set forth in my :above identified copending application, but .wherein the quantity of paste applied towallpaper and the like may be accurately controlled. A further important object of the invention is ,to provide a. wallpaper pasting machine in which the paste applying roller may have excess paste, :beyond :apredetermined quantity, expeditiously and conveniently removed therefrom.

' A very important feature of the invention resides in the'provision of anapparatus providing a combined paste receptacle and paste applying .roller journaled therein, together with a surplus .paste removing roller having :an advantageous .and novel coaction with the paste applying roller. T These, together with various ancillary objects and features of the invention, which will later become apparent as the following description proceeds, are attained by the present invention, a

:preferredembodiment. of which has been illustrated, by way of example only, in the accompa'nying drawings, wherein:

Figure l is a perspective view, parts being "broken away, of a preferred embodiment of the "invention;

Figure 2 is a top plan viewof the embodiment illustrated in Figure 1;

Figure 3 "is a vertical longitudinal sectional view thru the invention; and. V

Figure 4 is a vertical transverse sectional view taken substantially upon the plane. of the secition line 4-4 of Figure 3, and illustrating in dotted. lines the position of a piece or sheet of wall-' paper in proper position on the apparatus for pasting.

The embodiment of the invention disclosed hereinafter and in the accompanying drawings,

; includes the identical apparatus set forth in my above identified copending application. The same numerals have been applied to the present L drawings and description as have been employed my copending application, and like numerals designate similar parts throughout the various views. The numeral designates an open-endedcasing of any suitable size, shape andmateri-al but .preferably of sufficient dimensions to receive standard sizes of wallpaper therein. The receptacle I0 is provided with front and rear side walls I2 and I4, together with end walls 16 and,l8, the upper end of the receptacle being open'as above mentioned. 1

Extending through and between the front and rear walls l2 and I4 and preferably adjacent one of the end walls, such as [6, is a pivot pin 28 preferably positioned above the level of paste to be contained within the receptacle, for pivotally supporting thereon'a frame containing the various parts of the pasting apparatus. This pivot pin may comprise a bolt or shaft extending en"- tirely through the side walls l2 and I4, but in some instances may consist merely of stub axles carried by the front and rear walls and'extending inwardly therefrom. In any event, the pin 20 constitutes a hinge or axle about which an'end member 24 of the frame is hinged for pivotal movement, as by journals or brackets 26. I

The other end member of the frame consists of an end plate 28 provided with a horizontally and inwardly disposed shoulder'portion 30 which is adapted to selectively engage and rest upon a support or pin 22 appropriately positioned in the receptacle.

Although the pins 20 and 22 have been shown as separately applied to and extending entirely through the walls l2 and l4 of the receptacle l8, 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 providedwith 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. I

As shown best in Figures 1, 3 and 4, a U-shaped support bracket consisting of upstanding legs 48 and 44 connected by a horizontally disposediback portion 42 is provided, the latter preferably being rigidly secured upon the bottom portion or bottom wall of thereceptacle. The upper extremiand 38 have secured therebetweenlparallel:guide -rods or members 50 and 52 at opposite sides of 50.

the frame. 4 4 These guide rods 58 and 52 are preferablycomposed of bolts or the like having nuts '54 and 56 .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 se- Extending inwardly member are a pair of aligned stub axles 58 and 88 upon which parts is journaled a pasting'roll 62 of any suitable material which, as shown in Figure 4, is preferably positioned with its lower surface just above the bottom of the receptacle and with its upper surface above the normal level of liquid within the receptacle.

In my above identified copending application, this roll was preferably provided with a plurality of longitudinally extending grooves, and which constituted means for conveying and, retaining paste and applying the same to the surface of a paper with which the roll comes in contact. In the present instance, however, it is preferred, although not absolutely essential to the features of this invention, to form the roll 62 of a smooth, cylindrical shape, as clearly illustrated in Figures l and 4 of the drawings.

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.

As shown best in Figure 2, a plurality of longitudinally spaced studs 68 are screw-threaded through the rear wall [4 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 apparatus as so far described is exactly of paper may be accurately regulated, and

wherein surplus paste may be wiped from the roll and returned into the paste receptacle therein.

Pivoted to the upstanding legs 40 and 44, as by pivot pins 10 and 72, are a pair of supporting arms 14 and 16, which, at their lower ends, are

connected by a transverse shaft l8, upon which is rotatably journaled a roller 80. As will be readily apparent, the shaft 18 and the arms 14 and '16 may be integral so as to constitute a U-shaped member, or if desired the ends of the members 14 and 16 may constitute stub axles upon w'hich'and between which the roller 80 is journaled. In any event, it is intended that the roller 80 shall be rotatably mounted so that the same may revolve either in contact with or in fixedslightly spaced relation with respect to the cylindrical surface of the roller 62 during rotation of the latter in order to wipe or remove surplus paste therefrom.

In some instances, it may be found satisfactory to let the roller 80 rest upon the convex surface of the cylindrical roller '62 throughout the entire length of either of these members.

However, it is deemed preferable to provide means for spacing the roller 80 from the surface of the roller 62 by a predetermined distance, and such means may conveniently comprise sleeves, collars or bushings 62 and 84, which may be suitably carried by the roller 80 at predetermined positions thereon. In some instances, it

t may be found desirable to form the collars or spacer sleeves 82 and 84 as integral extensions or projections of the roller 80; while in other instances it may be found desirable to form the members 82 and 84 asv separate elements which are mechanically applied to'and attached to the roller 80. In the latter instance, it will be seen that various sizes of spacer sleeves or rollers 82 be permitted to remain upon the roller 62 and be applied by that roller to the wallpaper as will be apparent from Figure 4. Of course, excess paste will be removed from the roller 62 by the Wiping action of the roller 80.

From the foregoing, it will be apparent that the apparatus functions in identically the same manner as that set'forth in my previously mentioned copendingapplication, except for the addition of the means for regulating the thickness of paste applied to the roller 62 and for removing surplus paste therefrom, this latter means functioning independently of the rest of the device inorder to apply the desired quantity of paste to the paper. in an even and uniform film thereon. As will be readily understood, the excess paste removed from the roller 62 by the roller 86 will drop down into the receptacle as shown in Figure 4.

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 10. A sheet or 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 I2, beneath the two raised guide rods 50 and 52, and above the upper surface of the pasting roll 62, thence upwardly above the surplus paste removing roll 80, and thence upwardly as indicated by the arrow and over the upper support member 66 and then drawn outwardly over the front wall [2. When the paper has been disposed beneath the two guide rods 50 and 52, the end of the same is adapted to rest upon the support studs '68, whereupon the frame is lowered into the receptacle with the supportrod 66 received in the bifurcations 46 and 38. This depresses the paper slightly 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 '66 and the paper drawn about the guide member 56 and over the supporting .roll 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 into the device, and it is desired to use the end of the paper and to apply paste thereto.

Since, in customary operation, the paper hanger cuts off a piece of paper the exact size which it is desired to use, it is obvious that there can be no waste permit-ted 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 thepasting roll in initially inserting the paper in the device, the same becomes'coated with paste and then rests ,upon the supporting studs, while the guide rods 50 and 52 I are lowered into their operative position. The.

supporting rod 66 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 soilingthe unpasted side of the wallpaper by accidentalcontact with the pasting roll. r 7

From theforegoing, 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 transversely of said receptacle and secured besaid frame on opposite sides of saidpaste roll, a

, Wiper roll journaled on said upstanding arms and 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 may be resorted to, falling within the scope of the appended claims.
