WALL PAPER PASTING MACHINE Filed April 28, 1950 2 Sheets-Sheet 2 Patented Nov. 29, 1932 UNITE'DQF STATES PATENT OFFICE RUSSELL 1. MANN, or, 'coornnsnuiaa: rnnnsYLvANIA, assrenon ro Mortars L. sorRAnsnY, orAL nNrown, PENNSYLVANIA WALL PAPER TASTING miionmn Application filed April 28,

- This inventionrelates topasting machines, andmore particularly to an apparatus for pasting wallpapers.

An important object of the invention Is to provide an apparatus of this character which may be readily and cheaply manufactured and which will provide a pasting means el1m1- nating the ordinaryobjections of such machines in that it prevents tearing of the paper and piling up of paste in such manner that'it passes to the outer faceof the paper.

In the ordinary wall paper pasting machine it is necessary that the paste-applying medium, usually in the form of a roll, be madeof a length equal to the largest size of. wall paper which is to be pasted. When shorter sizes are used, portions of the paste-applying means are exposed, with the result that no paste is removed from these portions and a considerable quantity, accordingly, collects thereon finallypassingfrom these portions to the upper surface of the paper.

A furtherand more specific object of the present invention is the provision of a structure ofthis characterwherein means are provided for removing pastefrom unused portions of the roll. a A further object of the invention is toprovide an apparatus of this character which may be very readily and rapidly cleansed.

A further object of the'invention is theprovision of a structure of this'character having means whereby the paper maybe moved out plied thereto, thereby preventing collected paste from soaking the paper tosuch an extent that it tears readily and can be'handled only with considerable difficultyh i A still further object of the invention is to provide an apparatus of this character in which the paste-holding vat,in which the operating means is arranged, can be made of relatively small sizeand still contain as much paste as the vat of the ordinary pasting ap- ,paratus.

1 Astill further object of the invention is to provideapparatus of this character having the paper roll. mounting means of such con-l of contact with the paste-applying medium at 1930. 'serialNo. 448,014.

struction that the roll may be very readily if applied and removed. 1 a These and other objects I attain bythe construction shown in the accompanyingdrawings wherein, for the purpose of illustration,- I have shown a preferred embodiment of my invention and wherein: f V

Fig. 1 is a side elevation of the machine; Fig. 2 is a sectional view showing the paste applying mechanism; 1

Fig. 3 is a plan view of the machinewith the web and clamping means removed; and Fig. 4 is a fragmentary sectional view showing the paper elevated'from contact with the paste roll. a

Referring now more particularlyto the drawings, the numeral 10. generally designates a vat, the side walls 11 and 11a of which have at one end thereof a pair of projecting arms 12 and 12a mounting a paper roll shaft 13. Arising from arms 12 and 12-11 are a pair of upwardly-extending arms 14: equipped at their upper ends with clamps 15 to engage a bench or table 16. The arm site end swinga-ble from a position where-it clearsthe' arm ,12 to a position where it is disposed at the innerend of a slot 20 formed a in this arm. Adjustably mounted upon, this shaft adjacent the first-mentioned end thereofgis a collar 21 having a means 22 for securiing the same in adjusted positions and having attached thereto one end of a spring 23 the'opposite end of which bears against a disk 24 slidable upon shaft 13. .When the paperroll is placed between" this disk and the arm '12, the disk maintains friction thereagainst preventing too rapid unwinding of the roll or-any loosenesswhich would tend to cause misalignment.

Within the vat 10 adjacent the end wall 25 thereof'most nearly adjacent shaft 13 is disposed a pasting roll 26. Pasting roll 26-is hollow, comprising a cylindrical body 27 supopenings in the spiders affording space per mitting paste placed in the vat to pass to the interior of the roll. The spider. 28 has a squared shank 30 adapted to engage in a socket 31 formed in the inner end of a stub shaft 32 ,rotatably mounted in the wall 11' and having at its outer end a pulley '33. The spider 29 has a cylindrical gudgeon 34adaptw ed to seatin a bearing socket 35 formed in the inner face of'the wall 11-a, this wall having an inclined slot 36 extending from the top thereof to said socket,and affording a means for introducing the g'udgeon 34 into the socket or removing the same therefrom. Extending transversely ofthe vat in parallelism to roll- 26 is a shaft 37 having atone end thereof a stationary spring-pressed blade 38 bearing upon the corresponding end of the roll and at the'opposite end thereof a .longitudinally adjustable spring-pressed blade39.bearing upon the adjacent end of the roll. Adjustment of the spring-pressed blade 39 is effected through a collar 40 slidable upon the shaft and securable in adjusted positions thereon, this collar having attached thereto one end of a spring 41 surrounding the shaft and having its opposite end secured to the blade. Shaft 37 is bodily removable from the vat, having one end held in position in the lower end of a groove 42in the sidewall 11 bymeans of-shouldered latch springs 43 which may besprung out of latching position-to permit the shaft to be introduced to, or removed from, the lower end of the groove. The opposite end of the shaft is seated in a socket 44 formed in the wall 11-00. Thefront ends of the side walls have projecting upwardly therefrom a pair of arms 45 rotatably mounting a roll 46 the lowerportion of the periphery of which lies sli htly below a plane touching the upper end 0 the rear wall 25 and tangential to the pasting roll 26. One end ofthe roll 46 has secured thereto a pulley 47. connected-by a belt 48 with the pulley 33. When roll 46 is rotated, the roll 26 will be rotated.- I I Between the walls 11 and 11a is disposed .a. doctor bar 49 having a wiping strip 50 adapted to contact the under surface of a stripof paper passing from the pasting'roll to the-under surface of the roll 46. This doctor bar has its ends mounted in brackets 51 each comprising a channel closed at its lower'end'to afford a seat for the bar and each having a projecting stud 52 passed through an arcuate slot 53 formed in the supporting side wall 11 0r 11-a. Thumb nuts '54 mounted upon the studs serve to lock the brackets in adjustedpositions and to determine the tension with which ct-he wiping strip 50 engages the sheet. From. the roll 46 the paper strip passes .overxthe upperedge of a bar '55: connecting the upper ends of arms14tothe table 16; The upper surface of 1 "this "bar is preferably slotted, or otherwise formed as at 56 to provide a guide for the cutting knife used in severing the paper.

In order that the paper may be held out of contact with the pasting roll when the actual pasting is not taking place, the upper end of the side wall is, formed with a notch 57 in which is normally disposed a transversely-ex- .tendingbar 58. This bar is securedto the ends of arms 59, each of which is mounted upon a pin 60 'rotatably mounted inthe corresponding sidewall ll'or 11a. The outer end of one of thesepins has an operating crank 61, the weight of which together with the weight of the paper bearing upon bar 58 normall tends to maintain the bar in position in notch 57. The crank 61 may, however, be swung into engagement with a frictional spring catch 62 carried by the outer face ofarm 11 and when in this position will be retained against return movementuntil a predetermined pressure is brought to bear upon the bar. 3 When the arm is in'this position the bar 58 is elevated to an extent such that the paper web'VV from the roll R is lifted from the surface of pasting roll 26, thus'preventing this web from collecting'suificient moisture to become weakened or stained. An additional friction means for the web is provided between the bar 58 and the roll R, this web comprising a transversely-extending carrier 63 bearing a flexible strip 64 adapted to engage against the web. The carrier 63 has its ends mounted in brackets 65 carried by the adjacent faces of arms 12, l2-a and is held in, position against these brackets which are merely in theform of open seats by means of latch springs 66. V

In'use of the apparatus, the paper roll is placed in position upon shaft 13 and the tension means 63 is removed from its bracket 65 to permit the paper to be fed over the bar 58 and the pasting roll, and then replaced. The paper is then-passed successively over the doctor bar 49, under and about roll 46, and over bar 55 to the table 16, the vat having beenpreviously filled with paste. As the paper is drawnover roll 46, the tension applied theretov by spring 23 and by the tensioning means 63 insures rotation of roll 46 and this rotation is transmittedto the pasting roll 27 causing the same to rotate in the direction of the arrow of Fig. 2, and carry paste to andagainst the surface of the paper with a wiping motion. Excess paste is removed fromthe roll by blades 38 and 39 which have previously been properly adjusted. Roll 26 in its rotation, due to the fact that the paste enters the interior thereof, tends to assist in agitating the paste and keeping the same in properly mixed condition. When a. suflicient length of pasted paper has been withdrawn, the operator severs this stripand shifts the crank 61 to its latched position. When the pasted strip has been usedand a'second strip is'desired, he'merely grasps the severed end of the web and exerts a pull thereon. This pull must be suflicient to overcome the friction engendered by the tensioning means and the spring 23 and the tension of the latch 60 is set at such a. point that it will automaticallyv release to permit bar 58 to move to its normal fposition prior to any movement of paper r The pasting thus continues at the point where it was previously discontinued so that there are no unpasted portions'on the sheet.

It will be obvious that a construction of this character may be relatively cheaply manufactured and will eliminate the objectionable features of previous devices of this character.

It will also be obvious that the constructionemployed is capable of a certain range of change and modification without in any manner departing from the spirit of my invention I, accordingly, do not limit myself to such specific structure except as hereinafter claimed.

I claim: 1

In a pasting machine, a pasting means, a paper roll holder and a paperguide roll arranged at opposite sides of the pasting means, a bar between the paper roll holder and the pasting means over which the paper from a paper roll supported by said holder is adapted topass, said bar being normally disposed by gravity in a position such that'it exerts no force tending to elevate the paper from the pasting means, means for shifting said bar to elevate the paper from engagement with the pasting means, spring latch means for maintaining the bar in its elevated position, and means for applying tension to a paper roll upon said holding means such that the pressure applied by the paper to said bar automatlcally disengages said spring latchto,

permit the bar to assume its normal position.
