A TOR/Y5K J. KLESPER P'ASTE APPLYING DEVICE Sept. 19, 195 0 2 Sheets-Sheet 2 Filed June 2, 1947 INVENTOR. JOHN KLESPER l ATTO NE)- Patented Sept. 19, 1950 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to paste applying devices and more particularly to portable means for applying an adherent agent to one side of wall paper or the like.

The object of my invention is to provide a portable device to convey paste to one side of paper supported in a roll by the device.

Another object of my invention is to provide such a device that will apply a pre-determined thickness of paste to one side of the paper and distribute it evenly over the entire surface of one side of the paper.

A still further object of my invention is to provide a device that incorporates a means for severing the paper at any pre-determined length.

Still another object of my invention is to provide a device that is constructed in a manner to permit the component parts to be easily removed for cleaning purposes.

It is manifest to anyone familiar with the use of rolled wall paper, that it is sometimes quite a laborious and inconvenient procedure to apply an adhesive agent to one side of the paper and to cut the paper to a pre-determined length. With the device illustrated, described and claimed herein the paste or adherent agent may be conveniently conveyed to the paper and the paper may be fed or pulled over a coating roll and the surplus paste or adhesive agent'may be removed prior to the paper being cut to length.

The device may be easily transported and forms a compact unit having all the component parts arranged in a manner to permit their being mounted and replaced without the use of special tools or the like.

Other and further objects of my invention will become more apparent as the description proceeds and when taken in conjunction with the drawings in which Figure 1 is a perspective view of the entire unit in a closed position arranged for transporting.

Figure 2 is a top or plan View of the device in an open position showing the support for a roll of paper extending outward therefrom.

Figure 3 is a cross-sectional view of the assembled device with a roll of paper mounted outward therefrom and having the paper arranged for contact with the paste roller and the comb arrangement.

Figure 4 is a fragmentary cross-sectional View of the roller and comb arrangement with the paper shown in phantom passing over the comb.

Figure 5 is a fragmentary cross-sectional view of the front portion of the container illustrating the manner in which the cover may be held open in any position in its relation to the reservoir or lower part of the assembly.

Figure 6 is a side view of the paper roll support.

Figure 7 is a fragmentary perspective View of a portion of the comb, and

Figure 8 is a fragmentary View of a roller bearing arrangement showing the resilient retaining means employed for keeping the ends of the roller shaft in engagement with the bearings.

Similar characters of reference indicate corresponding parts throughout the several views and referring now to the same, the character II] shows the lower portion of the device forming an enclosure or reservoir into which the paste or adherent agent shown as II is placed. This lower portion or container I0 is provided at one of its ends with a drain plug shown as I2 which threadedly engages the wall of the container I 8. The front end of the container I0 is provided with an inwardly extending ledge or shelf arrangement I3 which is shown integrally formed with the outside wall of the enclosure II]. There is a cover unit shown as I4 which is hingedly attached. to the reservoir Ill by means of a piano hinge I5 or in any other convenient manner. The cover portion I4 is provided at its rearward end with a pivotally supported door I6 which is disposed to swing outward and may have its lower edge I'I serrated for severing, cutting or tearing wall paper or the like shown as I8 which passes through the device.

There is a main paste applying roll 19 which is mounted in bearings 20 and 2I in the reservoir section I0 .of the unit. The one bearing 20 is annular in construction and the other bearing 2I is of semi-radial contour as shown in Figure 8, and there is a resilient member '22 attached to a block 23 supported by the inner face of the end Wall of the reservoir II]. This resilient member 22 is disposed for retaining the shaft 24 of the roll l9 in engagement with the bearing 2| while the device is in use, and when the roll I9 is to be removed for cleaning it is merely necessary to move the resilient member 22 upward or it may be pivotally mounted so it can be moved sideways to release the end of the shaft 24 so that the roller I 9 can be removed.

I show a pair of outwardly extending brackets 25 which is provided with a hook portion .26 engaging the shelf or ledge I3 of the reservoir I0 and which is attached to the outer wall of the reservoir II] by means of a screw 21. The details of this support member 25 are shown in Figure 6. It is arranged for supporting a rod 28 onto which the roll of paper shown as 29 is mounted, and as the end of the paper 29 passes through and between the cover [4 and the ledge I3, a pair of eccentric levers 30 shown pivotally mounted at 31 may be moved to raise or lower the cover member [4 to permit the .paper l8 to enter the entire unit.

The cover member i4 is also provided with a small roller 32 which is longitudinally disposed within the cover and is located atapoint near the outer. peripheral surface of the main roller l9 onto which the paste adheres as it is being revolved. This small roller 32 has for its purpose keeping the paper I8 in engagement with the upper portion of the roller l9 onto whichtthe paste II has been applied.

There are alsotwo auxiliary rollers 33 and'33' which are longitudinally disposed and'mount'ed on

shafts

34 and 34 which are journaled in bearings within the wall of the cover member 14'. These two auxiliary rollers 33 and 33' have for apurpose 'keeping'the'paper 18 in frictionalengagement with a comb member shown as 35 which is longitudinally disposed adjacent to the auxiliary rollers 33 and 33' when the device-is in a closed position.

' This comb member 35 is hingedly supported by thewalls of the reservoir member a l and consists of a plurality of fingers or spaced members 35 which contact'the paste or adhesive agent on thebottom of the paper l8 where it has been placed by the rotation'of the paste roller 19. The rearward wall 31 ofthecomb member 35 is not slotted and is employed'for brushing off the excess'plate where the spaced members 36 of the comb '35 will distribute the paste evenly along the surface of the paper, the rear wall-31 of the comb member 35 will permit the 'comb'35 to'be pivotally adjusted as shown in Figure l, and this adjustment will determine the'amount of paste that will be retained on the" lower surface of the paper 18 as it passes over the comb 35.

' The paper I8 is permitted to leave the hinged or pivotally mounted door [6 at the rearward end of the cover I4 where it is pulled by the operator, and as'the paper l8 is-pulled throughthe entire device it will pass over the paste roller l9 and'will be taken from theroll 29 suspended by that bracket 25 in the forwardend of the entire uni 'It' will be manifest to anyone familiar'with the art that this type of device isvery compact in itsfconstruction and maybe: assembled and disassembled'for use in a comparatively short-period of time. 7 It will also be notedthat I 'show apair of .i'resilient clamp members "39 which are attached to the inside of the top of the coverrimemberiM and are employed'toretainthero'd 28 ontoawhich the roll of: paper 29 is applied. It will alsozbe' noted that the brackets25'may be adjustably and slidably moved sideways, eitherapart or towardone another to :guide the paper and support the various widths of paper that maybe used-and put through the device.

'The construction of thecomb member 35-is such that-the quantity of adhesive agent applied to the paper may be' governed byhaving the individual prongs or sectional members'fitficontactingthe-paste-onthe bottomofthe paper P8; :{Ihis will cause the-paste to be'spread evenly vover the entiresurface, and the rear-wall 31 of the comb member :35 will cause the surplus paste to be scraped-off the paper and depositedback-intolthe reservoir ill where it will be used over again.

In .the chosen embodimentsof my invention thereare many features notlheretofore :disclosed 4 I in the prior art and although I have shown a specific arrangement of the component parts, I am fully cognizant of the fact that many changes in the form and configuration of the component parts may be made without effecting their operativeness and I reserve the right to make such changes as I may deem necessary or convenient without departing from the spirit of my invention or the scope ofthe appendedclaims.
