wall paper pasting and trimming machine, the senile beingshoWn attached to a table or suitable support, and parts heing broken away to better illustrate the machine;

l is a crosseection through the ma chili certain parts shown in an adj ueted position, in dotted lines supper-tin,u,

, and trinuned, either along one or both ed gee,

and semi-ed in two parts or strips, if desired.

The machine includes a frame 1 and a paste tank 2. The frame is made, preferably rectangular in shape, having the side rails 3 and 4- the front rail I. and a rear rail 6. The rail 6 has an overlying: angular portion 7 adapted to rest on a table or other support The tank 2 is of suitable shape and is adapted to detachahlr secured to the frame 1, tl'lrough hinged catches 8 carried on the front and side Walls of the tank 2,, adapted to engage lugs 9 secjaired to the front and side rails 5, it) and l of said frame. All operative iarts of the ma chine are carried on the frame 1, and by detaching; the tank it may be easily filled with paste and access had to all operative parts, although to get to and. remove such operative parts it is not necessary to remove said 'lrame. l

The rails 3 and 4; of the frame are rovided with depending hangers 10 hav inn; hearinr s 1]., These hangers, when the frame 1 and the tank 2 are assembled, eX- tend dou 'uto the tank 2 alongside of the side Walls of the tanlt, and journaled in said hearinu's 1] are stub shafts of the pasting roller It in understood I may provide the roller with etub shafts at each end. or with one shaft extending through the roller. ",lhe roller' 12 constitutes one of the imocn'tant features of the machine.

sprin tenuniversal use.

trimming machines,.the pasting roller has the exception of brass, they rust, and all stroys the c'overin; g.v

being dead and glossy, they would not hold t-he paste and therefore not a success. Attempts have been made to make the roll of wood, but it dries out, and when hollowed out they warp. Tubular tin rolls have been tried, with a covering of some suitable material, but these have not been a success, because the acid in the paste eats it up and deh [y pasting roller is made of aluminum and hollow. Being hol low, it agitate-s and constantly mixes the paste as it revolves, thus keeping the paste always in. workable ctmdition. Aluminum is porous and acts morelike wood without any of its disadvant-z-iges. The suriace of the roller is made rough by planing, or by other suitable means. Such a surface will hold the paste and insures the same being uniformly distributed over the surface of the paper and it will not rust. Experience has. taught that a pasting roller made of aluminum, with its surface roughened, will do the work, where all others have failed. Said roller .12 is provided with slightly raised annular portions 13 of suitable width providing frictionalcontact points for the paper, between the trimming roller and said pasting roller] The drawings do not show the surface of the roller 12, roughened, except thesurface of one of the annular portions 13, see Fig. 6. Here the annular por tion 13 is shown provided with angularly disposed grooves 13", whiclu in addition to giving a more eflieient gripping surface, to provide traction to roll the paper through the machine, also provides for taking up the paste and distributing on the paper at the traction points.

14c designates the trimming roller. This roller has stub shafts or trunnions 15 and journaled in bearing plates 16 and 17. each of which is pivoted at 18, to a side rail ofthe' frame 1 and provided with an adj us'ting screw 19 having a threaded conneetion' with a. nut 20 on the side rail of the frame. The plate 16 has an opening 21 therethrough, into which may be inserted and have a bearing, a stub shaft or trun nion of'the roller 14:, and the plate 1.? ha, a curved slot 22 opening out of the upper edge of'the plate, into which the short shaft or trunnion 15 of the roller 1; may be insorted and have a hearing. The roller 14-, when in position, is immediately above the roller '12 and cooperates therewith, when paper is fed or drawn through the machine, toreceive paste from said roller 12. Adjusting the screws 19 will raise or lower the hinged'plates 16 and 17, thereby adjusting the roller 1+, relatively to the roller 1'2, so

as to provide for the passage of very thin or very thick paper between said rollers, and also to take care of any unevenness in. the thickness of the paper.

Q3 designates a cutter supporting shaft. This shaft is preferably square in cross-section, its opposite ends being rounded and having a bearing in the side rails 23 and l of the frame. Slidably carried on said shaft are a plurality of collars 24-, each collar having a pair of upwardly extended spaced cars 25 and a laterally extended boss 26 provided with a threaded opening there through. Pivotally mounted between each pair of ears 25, is an arm 27, and each arm is bifurcated at its forward end between which is journaled a suitable paper cutting disk 28. The rear end of each arm 27 is provided with an enlargement having an opening through which is carried a threaded stem 9, which has a threaded connection with the threads in the opening in the boss 26 on the collar 2-1. Between the enlargement 30 of each arm 27, and the boss 26 of each collar 2'1, and on the stem 29, is a coil spring 30 to provide for flexibility between the cutting disks 2S and the pasting roller 12. The stems 29 above the arms 97 are pr vided with collars or shoulders 30, 0 that when the stems 29 are screwed down, the ends of the arms 27 on which are journaled the disks 28 will be raised, elevating said disks, the springs 30" acting to hold the cutting isks 28 in operative position and yielding to permit the disks 28 to rise when necessary to conform to the work. Each stem 29 has a finger-hold portion I l. It is understood, that the collars 21: may be slid along the square shaft to any posi tion, wiiereby one or both edges of the paper may be trimmed, and if desired, one of the cutters positioned so as to cut the paper into two parts or strips.

The cutter supporting shaft 23 is adapted to be rocked in its bearings for the purpose of raising the cutting disks 28 from the position shown in full lines in Fig. 2 into the position shown in. dotted lines in said figure, whereby the trimming roller 11- may be re moved from its hearings. or replaced, as the case may be. To rock the shaft 2 I ])1'o-- vide levers 32 secured to each end thereof.

Secured to opposite ends of said cutter supporting shaft 23 and located within the frame 1, are plates In these plates are journaled a rod 36 to which is secured a brush 37 made up of a series of bristles sccured to the rod and arranged. somewhat in the manner shown in Fig. 1. It intended that the rod 36 may be rocked in its bearings, so as to ad'iust the brush 37, which in operative position, wipes the paper passing aroi .l the trinnning roll 14 so that only a given quantity of paste will remain on the ltll) ill-3 'I ll) ii ii paper as it passes from said trimmin. roll, to adjust the. rod 36 and the brusi All", I provide an arm 38 secured to one end of said rod and connected with the outer end of said arm is a threaded rod 39 which passes loosely through a boss a-i-(i connected with the plate 35, and having a threaded engagement with said rod 39, and tearing against the boss 40, is a thumb nut l1. It is obvious that upon turning; the thumb nut 41, in one direction, the rod. 39 will be moved upwardly, oscillating the arm 38 and rocking the rod 36 so as to cause the brush 39 to bear against the paper passing over the trimming roll 14, and if the thumb nut 41-1 is turned. in the other direction, it will move the rod 39 in a direction which will oscillate the arn'i 38 and lock the rod 36 so as to relieve the pressure of the hrnsh 37 against the paper passing over the trinnning roll 14. The thumb nut 41, the threaded rod and the arm connection 38 with the rod 230. may be employial by the operator :tor adjusting the initial position of the brush 37. Through the agency of the thiunh not i1. and its connections with said rod 36. the operator may adjust the positi on oi the hrush 37 at any time, and by means of the lore s 32 and pivotal latches 34:, he nary incre .se the pressure of the brush against to paper, or release the pressure wherehr more or paste may be-wiped oil; also place sufiiip-ient tension on the cutters ES to pro iierly trim the paper.

he latches 3+1: are pivoted on the rails 3 and it at 33, and each latch has the weighted and i i to retain the latches in operative position, their niovernentin one direction heinp; limited by screws 33 with which they engage. When the levers 32 are depressed and caused to have a locking: engagement with the on aging portions of the latches ii. he cutting: disks :23 and the brush 37. will he placed in an operative position, see Fin: and will hold the parts in this po- -:ition; it being: assured that thethumb nut l1 has been adjusted so that the brush. 37 is hearing agnrinet the paper passing around the trimming roll. 14L in a manner su'llicient to wipe oil the excess paste.

To protect the cuttersupporting: shaft Fifi. and the slip 57011711! and adjusting means for the cutters. trom being smeared or be ruining; clogged with paste during the to tation oi the pasting: roller 12, which constantly agitates and, lifts the paste during its rotatioin l n'ovide the guard 41. best -ieen in Fig. 2. which said guard extends tl.il(lt-irl the machine parallel with the roller flii and above and to one side of the same. and 3-. cured at its opposite ends to the plates 32?. which in turn are secured to the opposite ends oi the cutter shaft '23.

"lhe paper sup iorting reel .01" spindle is designated &2, and when in operative position on the. frame, is journaled in the slotted bearings 43 secured or attached to the inside faces of the side rails 3 and 4. The reel is located. at the rear of the frame and. when the paste tank 2 is connected or attached to the frame 1, the reel as shown, is outside of the tank, or located to the rear of the rear wall of the tank. The reel comprisesthespindle 42 and the disks 41-4: and 4-5, which are adapted to be screwed on to the opposite threaded ends to of said spin dle -12; a lock nut 17 being provided for locking the disk or in its adjusted position on said spindle 42. i i

To place a roll. of paper on the reel, the disk 45 is removed and the disk 414C adjusted. and locked. in position. The position of the disk 44. on the spindle 42 will detern'iine whether or .not it is desired to trim that edge of the roll, and also whether ornot paste will he applied the full width of the roll. After the roll of paper has been placed on the spin dle, the disk 45 is screwed on to the spindle so as to confine the roll of paper between the two disks and guide the same through the machine. The paper it is drawn ofl of the reel, will pass over a guiding roller 48 journaled on the side rails 23 and 41;, at a point preferably just above the edge oi the rear wall. of thetank 2 so as to protect the paper as it is carried from the reel into the tank. The paper is passed over the pasting roller and around the trimming roller 14:, in the manner shown in Fig. A flat spring 4.9 which is secured to the side rail 3, is adapted to have a healing against the out side surface of the disk =14 ofthe reel. This s1 ina will place a tension. on the reel and retard its rotation suflieiently to prevent the paper from unwinding. except asit may be drawn. through the machine, in the manner explained.

designates a cut-off shield and gage. 'lhis shield. and gage s of a 'iproximatel the same width as the :trame .1. and is pivoted at 51 on the overlying angular portion '7 oi the rear rail 6 of the frame, so that said shield and gage may be raised out oli' position to permit the insertion or removal of the reel for applying a roll. of paper there to. or reniovinp, the same therefrom. When in lowered position. the forward edge of the shield and cage 50, rests on the trinimin 5; roller 1 11-. so that the paper leaving the trimming roller 14 will pass up over said shield and gage. somewhat in the manner shown in Fig. 2. This shield and gage will protect the paper and prevent the same becoming entangled or aisni.11,a around the roller in the case that it should bGCOIl'lP torn or split. The shield and gran-c 50 is provided with a plurality of cutting edges These cutting ed extend crosswise of the machine and are soispaced that an operator when he desires to sever a pasted strip.

liO

lllii of the cutting edges 52, selecting that cutting edge which will enable him to sever the strip with as little waste as possible.

These cutting edges may be spaced with a view of permitting the operator to cut a strip from the roll, so as to match up the paper with as little waste as possible, that is to say, where you have a dro-pmatch, afterit is ascertained which cutting edge 52 to use in severing the paper, so as to bring about a proper match of the par er, such edge will be used throughout the pasting and out ting operation. The cutting edges 52 are spaced at predetermined distances so as to best adapt the machine to the uses of drop matching. These cutting edges are further useful wherethere is no aim to bring about a drop match but where in the event the paper is drawn out more than intended, the operator running his knife along one side of the cutting edges best suited for the purpose, thereby obviates unnecessary waste.

For supporting the machine'on a table orother support, I provide a bracket 53. This bracket has an arm 54: adapted to engage the under side of the table or support 55, and is further provided with a rest portion 56 upon which rests the tank 2, and somewhat as shown in Fig. 2 The bracket 53 includesa bar 57 adjustably connected I with the main portion of the bracket by means of a bolt 58, passing through the bar 57 and through a'slot 59 in said bracket. The upper end of thebar 57 is bent and formed with a right-angled portion ()0 adapted to be seated in a cut-out portion in the table or support 55, so that its upper face is flush with the upper face of the said table or support. 7 The bar 57 is adjustable on the bracket so as to adapt the bracket to different thicknesses of tables or supports in connection with which it is desired to use the machine.

It has been shown and explained, that one end of the shaft of the roller 14 is journaled'in a slot 22 opening out of theupper edge of the plate 17. To yieldingly hold this end of the shaft in its bearing, I place on the shaft a sheave wheel 64 around which passes a belt 63, which also passes around an idler pulley 62 connected with one end of a 'coilspring 61, the opposite end of said spring connected with the table or support 55. To remove the roller 14 the belt 63 is slipped off the sheave wheel 64, as will be understood.

In operation, the shield and gage 50 is swung up out of the way, the reel removed and a rollof paper placed thereon, the disks 4A and 45 adjusted on the spindle of the reel to properly position the roll of paper for pasting and trimming as it is drawn through the machine. The tank 2 is detached and filled *with paste and resecured in assembled position on the frame 1. The paper in being threaded through the machine, is passed over the guiding roller 48, over the upper surface of the pasting roller 12, around the trimming roller id and over the shield and gage 50. The cutting disks 28 are positioned at suitable points on the out tcr supporting shaft 23, according as it may be desired to trim one or both edges of the paper, or for severing a roll into two parts or stips, and one or all of such cutting disks adjusted so as to bear down upon the paper passing over the trimming roll 14, as may be desired.

The brush 37 is adjusted in a position which will wipe off the paper as it comes from the pasting roller, it being obvious that said brush may be adjusted so as to wipe oi? more or less of the paste, as is (l\- sired. As the paper is drawn through the machine and over the pasting roller and be neath the cutters, paste is applied thereto and the paper out or trimmed. When a strip of suitable length has been drawn from the machine, the operator will, by means of a suitable cutting tool, pass the same over the paper and along one of the cutting edges 52 of the shield and gage, and sever the strip from the roll.

I have described the pasting roller as having a roughened surface, which as stated, facilitates in holding the paste to be applied to the paper and said roller being hollow, the paste is kept in agitation and constantly mixed, and as the paper is drawn over the pasting roller and around the trimming roller, the action of drawing the paper, rotates the trimming roller and the Same having frictional engagement with the annular raised portions 13 of the pasting roller, will rotate said roller. The raised portions 13 on the pasting roller are so very slight, that there is not much space, if any. left between the surface of the pasting and trimming roller, and as the trimming roller may be adjusted relatively to the pasting roller, it is obvious that paper of any thickness may be passed between the two rollers and the application of paste to the paper assured.
