.20 Claims.

My invention relates to a machine for cutting,

pasting and folding wall paper.

It is a purpose of my invention to provide a machine of the above mentioned character that is simple in construction and which will measure off a length of wallpaper as may be determined by setting the machine to the length desired, which will prevent operation of the machine after the desired'length of paper'has been cut and had paste applied thereto, and which cannot be again operated until the machine is reset to cut the same length or any other desired length ofpaper. I

It is a further purpose of my invention to provide a machine of the above mentioned character, which is provided with cutting means for trimming the edges of a, roll of wall paper, and

which is also adapted for cutting out borders having straight edges, or widths of paper less .than the full width of the roll for fitting in corners or around openings, as may be desired.

Furthermore the cutting mechanism is so constructed and arranged that the paper will be cut substantially through, but not entirely through, so as to be not completely severed at the cut, whereby the portions of the paper that constitute the trimmings, or cuttings, will remain in place until the paper is removed from the machine after having had the paste applied thereto and after having been folded in the customary manner for easy handling after having had the paste applied thereto. The portion of the paper that is tobe removed can then be severed very easily from the strip that is to be used, by merely pulling off the trimmed edge portion, or other width of paper that is to be discarded.

It is a further purpose of my invention to provide a machine of the above mentioned character, into which a roll of paper can be readily mum period of time without the removal of any large numberof parts of the machine.

It is a further purpose of my invention to provide. a machine of the above mentioned character, in which the paste container, the paste roll and other parts that might require daily cleaning, can be removed from the machine as a unit and also readily replaced in position.

It is a still further purpose of my invention to provide a machine of the above mentioned character with means'for determining the length of paper that is to be cut 01! with paste applied thereto, comprising means for rotating the paste applying roller, measuring means operated by the 'movement of the web of paper through the machine, and stop means actuated by the measuring means for halting the operation of the means the particular details shown or described, except as defined in the claims.

Referring in detail to the drawings, m machine is provided with a pair of side frame members 20, which are secured in spaced relation to each other in any desired manner, as by means of cross members 2| having spacingsleeves 22 surrounding the same. Said side frame members 20 have depending bracket members 23 thereon that are provided with tubular sockets 24 for adjustably receiving tubular legs 25, whereby the height of the machine can be adjusted as may be desired, said legs being held clamped in adjusted position by means of suitable clamping screws 23.

Each side frame member 23 is provided with a threaded boss 21, which receives a screw-threaded headed member 23, whereby said members 23 are adjustable toward and away from each other. The inner ends of the members 23 are received in suitable sockets in the end of the shaft 23, whereby said shaft is rotatably mounted between said members 23 on the frame. The shaft 29 is provided with a threaded portion 30 for receiving the threaded hub portion 3| of a flange 32, a similar flange 33 being fixed on the shaft 29 in any suitable manner at the opposite end thereof, said flange 32 being removable and adjustable toward and away from the flange 33, so as to provide a reel of a width corresponding to that vent disengagement of the drum therefrom, and a collar or head 41 being provided on the other end of the shaft 4| to hold said shaft in assembled relation on the side plate 23. The drum 44 is provided with a continuous thread 43 on the outer surface thereof, the purpose of which will be described below. a

The roll of paper 34 is placed on the shaft 23,

- the flange 32 being removed for this purpose, and

after the roll 34 is in .place, and the flange 32 has been replaced the web of paper 43 extending from the roll 34 is placed over the shaft 33 incontact with the roughened rollers 31, as will be obvious from Figs. 1 and 3. Said web or paper 43 is also passed over a backing roller 50 forming part of the cutting mechanism, over a paste aplying roller BI and over a cutter bar 32 and a guide bar 33 to the exit end of the machine, in

threading it through the machine, ready to be operated upon.

I order to assure intimate contact of the web in with the rollers 31, and tension it, so that the measuring mechanism actuated therebyv will be accurate in its operation, and-in order to have smooth contact of the web 49 with the backin roll 50 of the cutting mechanism, a pair of rollers 54 and 55 is provided located on opposite sides I ing for said rollers comprises a pair of side memof a roll of wall paper 34 mounted ori the shaft 29 between said flanges 32 and 33. Suitable means can be provided, such as set screws, for holding the flange 33 in position and for holding the flange 32 in adjusted position.

Mounted in suitable bearings 35 in the side frame members 20 is a shaft 36, which forms part of the measuring mechanism. Mounted on said shaft 33 so as to be fixed in position thereon, are roughened or knurled rollers 31, said rollers being arranged at closely spaced intervals along said shaft 36. One end of the shaft 38 has a gear 38 fixed thereon, a collar 33 being mounted between said vgear'38 and the bearing member 33, said gear 33 meshing with a gear 43 mounted rotatably on a stationary stub shaft 4| mounted in a boss 42 on the one side plate 20, as will be obvious from Fig. 6. The gear 4|! has a tubular sleeve-like member I3 projecting therefrom, secured thereto by means of a flange l3. Said tubular member l3 being thus mounted on the shaft 4| to rotate with the gear 43. Said sleeve l3 has an elongated hub portion 43 of a drum 44 mounted thereon, said drum being detachably connected with the sleeve l3 so that the same can be rotated either with the sleeve or independently of the sleeve by suitable means, such as the thumb screw 45, a collar 46 being mounted on the shaft 4| to prebers 63 having the bars 53 and 51 extending between the same and having an upward extension through which the bar 33 extends, said bars 56,

51 and 53 securing said side members 53 together in predetermined spaced relation, being provided with threaded ends for receiving the nuts. 60 for securing the parts in position.

Each side frame member 20 is provided with a bracket 3|, shown more in detail in Fig. 11, fixed thereto by suitable fastening elements 62, each of said brackets having a hook-like flange portion 33 receiving a lug 64 on a member 58 under the same. Each member 53 is also provided with a lug 65 projecting therefrom, which is engaged by the clamping screws 86, said clamping screws being screw-threadedly engaged with brackets 61 on the side frame members of the machine. It will be obvious that the entire frame made up of the side members 53 with the rollers 54 and 55 extending therebetween can be removed by merely unscrewing the two screws 66 and slipping the lugs 64 out from under the overhanging flanges 83.

The roller 30 is made of hardened steel and cooperates with cutter members to trim the side edges of the roll of wallpaper and to cut the same in strips of desired width 'for placing around door and window openings, in corners, and other places where less than full widths of wall paper might be used, and for cutting borders. Cooperating also with the cutting mechanism is a scale, which comprises a cross bar 63, which is secured to upstanding brackets 33 on the side members 20, and serves as a means for holding the side members in properly spaced relation, said bar having a scale 10 thereon that is marked in ir'iches and fractions of an inch in a customary manner.

Mounted between the side members at in se- .cured thereto. and serving to hold said side members in properly spaced relation, is a bar I I which is rectangular in cross section. Said bar II may be provided with threaded ends extending through A lever 16 is mounted pivotally'on each of. the shafts, or rods, 14, each of said levers having a -pointer 'I'I mounted thereon, which cooperates with the scale 10 in an obvious manner. Each 1 lever also hasa curved upper end portion 18, i which has a thumb screw 19- screw-threadedly' mounted therein, said thumb screws I9 engaging at the lower ends thereof with the rod-like members I6 and serving to hold the levers I6 in adjusted position along the rods I4 and I5, and also serving to exert the desired pressure through the levers on the cutter members cooperating with the roll 60. Said cutter membersare rotatably mounted in bearings in enlargements 80 in the bifurcated lower ends of the levers I6, said cutters being provided with beveled edges so as to provide cutting edges, which are not knife edges, being somewhat blunt, but sufliciently sharp to cut the web of paper 49 in cooperation with the hardened roller 60. It will be obvious that the cutters II, the cutting edges of which align exactly with the tapered ends of the indicator members IT, can be' adjusted to any desired position within'the limits provided by means of the rodlike members 14 and 16 to trimthe edges of the roll of paper as may be found desirable.

- strip ofl. one side of the web and sometimes off the other side of the web, or even both sides thereof. By providing the scale and providing adjustable cutter members that'cooperate with the scale, widths of paper of any desired character can be cut on my machine, and in order to provide such adjustable cutter members the bar II is provided, said bar II being provided to ob- I vtain an adjustable mounting for intermediate cutter members that can be moved into position to-cut the desired width or strip of paper that may be necessary for a narrower space thanthe normal width of a roll ob paper, and which can be adjusted so as to be entirely out of cutting Said reduced nub portion a receives tion 92.

- the tubular body portion 99 of a lever having an arm 90, having a cutter member II mounted in suitable bearings in the bifurcated lower end of v saidarm 90, andha'ving an arm 92 extending therefrom in substantially the opposite direction to the arm 90, which is adapted to eng sewith the stop member 91 to hold the cutter member 9| in elevated position. as shown in Fig. l, and as shown for one of said cutter members in Fig. 3.

When it is'desired to engage a cutter member g with the web of paper 49 it is only necessary to slide the tubular portion 89 thereof lengthwise on the hub portion 98, so as to disengage the arm 92 projecting rearwardly therefrom, from the stop 81. and then replace the lever in position by sliding in the opposite direction on the hub portion with the rearwardly extending arm 92 thereof above the stop 91. The arm 92 has a thumb screw .94 screw-threadedly mounted therein,

which can then be adjusted to engage the upper face of the stop 91 to cause the cutter member 9| to engage the web of paper with the desired pressure. Each cutter member is provided with an indicator, or pointer member, 93 cooperating with the scale I0, to'indicate the position of said cutter member, said pointer, or indicator member,

position when only the edges are to be trimmed,

and which can be readily and quickly adjusted to position lengthwise of the scale and into and out of cutting position.

The mounting of each of these intermediate cutter members on the transverse bar 'II comprises a mounting member, such as shown in Fig.

.5, having a body portion 92, which has a recaligning with the cutting edge of the cutter member 9I. Said thumb screws 04 also serve to hold the cutter members in adjusted position on the bar II.

Pivotally mounted on the shaft I5 are links 94, which pivotally carry a rod-like'member 95 having sleeves 91 rotatably mounted thereon, on which the rollers 96 are mounted. Mounted in fixed position on the links 94 are the arms or links 90, said links 94 and 98 together forming a bell crank lever. Pivotally mounted in the outer ends of the arms 98 is a rod-like member 99, which is located above the rod-like member 95. A bracket member having a hub portion I00 is mounted on the rod-like member 1 I, being adapted to be fixed in position thereon by means of a set screw. Said bracket has an arm I02 ,ex-

tending therefrom, on which is pivotally mounted a lever I03 having a handle .portion I04 and a hook-like end portion I 05; which is slotted to re.- ceive the rod 99 having a plurality of recesses in the upper side of the slot for adjustably receiving the rod-like member 99'. It will be obvious that by adjustment of the handle member I04 the lever I03 can be adjusted to vary the position of the rod-like member 99, and thus the tom ofthe slot and be lifted by means of the hook-like end portion- I06 of the member I03, to

thus move the rollers 96 away from the paste roller ii. A post IOI is provided on the member I00, witl'rwhich a loop-like member IOI' on the handle is adapted to engage to hold the lever in such position that the rollers 96 will be elevated. The paste roller Si is mounted for rotation within the paste receptacle, or pan, I06, which,

preferably, has a sloping bottom so as to place the lowest'portion. I01 thereof substantially below the axis of rotation of the paste roller 5i. Said paste roller is mounted to be removable as 8|, said roller being, preferably, hollow and having end walls I I4 on which the shaft portions II3 are fixed. The shaft II3 can extend entirely acme I be n preferably, of hardened steel and bein detachably secured to said body portion I38 by a fastening element Ill. The lever I4! is urged toward a grooved stop bracket I42 provided on the frame member 28 by means of a coil spring. or similar resilient means, I43 chilling the headed 1 fastening element I44 on the 'bodyportlon I38 through the roller if desired, or stub shafts can I be utilized. Fixed on one of said shaft portions H3 is a pinion II8, said pinion being removable of the lever and having the other end thereof secured to the frame 28 in any suitable manner as by a' bolt 88. The lever is mounted on a pivot I48 and is provided with a handle member I48 for lifting the same against the tension of the along with the roller and the shaft and the pan,

so that the entire unit can be removed for cleaning paste off the same, when this is desired, the unit made up of the roller, paste pan and driving means therefor being readily transportable into position under a water faucet for washing the same of! when this is desired.

The-supporting member I88 is also provided with upstanding supporting members, or brackets,

H8 and H1 thereon. Said brackets II8 support the bar -I I8 for removing excess paste from the surface of the paste roller 8|, while the brackets 1 support the cutter bar 82 having a slot 8 A therein, with which theusual hand cutter tool cooperates to cut off the length of paper at the point where the same overlies said slot H8. The pan member I81 rests at one end thereof and along its inclined bottom on the top surface of a bracket I28 provided on each side frame 28 of the machine. Any suitable means; for detachably fastening the pan in position, so that it and the parts carried thereby will not move out of position, may be provided, such as the ears- I2l thereon adapted to receive a thumb screw I22 engaging a suitable threaded opening in each side frame member 28.

I Means for driving the paste roller is provided comprising a pinion I28 rotatably mounted on a stub shaft I24, which is rotatably mounted in a suitable bearing I28 in one of the side frame members 28, and which is provided with a collar I28 pinned thereto for holding the same in position in the bearing. Said pinion I23 is located toward the end of the machine carryin the roll of paper from the pinion I I8, so that upon pushing the pan I81 into position these pinions will mesh. A bearing I21 is also provided in the side member I28 for a shaft I28, which has the pinion I29 fixed thereto, meshing with the pinion I23, and which has a sprocket wheel I38 fixed thereto, over which the sprocket chain l3l operates.

Said shaft also has pinned thereto the hub portion I32 of a. crank I33 having a handle I34 thereon. Thus the shaft I28. and through the pinions I29, I23 and 8, the paste roller8l, are rotated by rotating the crank by means of the handle member I34.

The sprocket chain I3I sprocket wheel I38, which is mounted on the reduced end portion of the roller 88 to rotate with said roller, said'reduced end portion being indicated by the numeral I38 and having a ratchet wheel I31 mounted thereon, which is shown more clearly in Fig. 9. Both the roller 88 and the paste applying roller 8I rotate in a clockwise direction as viewed in Fig. 3, and the ratchet teeth are so positioned on the ratchet wheel I31 that such clockwise rotation of the shaft portion I38 and thus of the roller 88 will be prevented by engagement of the tooth, or pawl, I38 with said ratchet teeth. The pawl I38 is carried by the enlarged body portion I33 of a lever I48, said pawl, or tooth,

spring I43 when this is desired. Said lever I48 is provided with a downturned end reduced portion I41 forming a finger, the purpose of which will be described below.

Screw-threadedly mounted on the thread 48 on the drum 44 is an internally threaded ring member I48, which carries a bracket I48, upon which a block I88 is mounted, having an opening I8I therein adapted to receive the depending ilnger portion I41 on the lever I48. A scale I82 is slidably mounted in a corresponding recess I83 in the block I88, and an adjusting screw I84 engages .said scale I82 so that the zero point on said scale can be accurately aligned with the center of the opening I8l. The depending finger I41 also cooperates with the scale l82, which is provided with a set screw I88 mounted in the slot I88 for fixing the same in adjusted position, and the scale provided on the scale member I82 is callbrated in feet.

The drum 44 is, of course, rotated by means of the shaft 38, carrying the rollers 31 and the ratio of the gears 38 and 48 is such that each time that the rollers 31 rotate sufilciently for a foot of also operates over a length of the web 48 to pass thereover, the drum 44 will make one turn and accordingly the marks on the scale indicate one turn of the drum, which equals one foot of length of the web 48 passed over the measuringrollers. A scale is also provided on the face of a ring I18 mounted on brackets I18 (see Figs. 1 and 2) with which a pointer I81 mounted on the drum 44 cooperates, said scale dividing the ring I18 in twelve parts to thus indicate one-twelfth of a turn of the drum 44, or inches of length of the web 48 passing over the measuring rollers 31.

In order to cut off and apply paste to a, desired length of paper from the web 48, the web is cut oil at a suitable matching mark, by running a cutter transversely thereof over the groove I It on the cutter bar 82. These matching marks are dots or similar markings provided to indicate the proper places to cut oil the paper, printed thereon, so as to enable the paper hanger to match the pattern on adjoining strips of paper. With the paper in this position the thumb screw 48 is turned to release the drum 44 from the sleeve I8. The lever I48 is'then lifted to disengage the finger I41 from the opening I81 and the drum 44 is rotated on the sleeve l8 until the desired length of paper to be cut off is indicated on either the scale I82, or the scale I82 and the scale on the member I18, if a, different amount than an even foot is to be cut off. The exact alignment of the finger I41 with a mark on the scale I82 is possible due to, the provision of an indicator I83 on the finger I41. However, the scale on the ring I18 is so calibrated that when the 12" mark on said scale is in alignment with the pointer I81, the indicating member I88 will be exactly aligned with a foot mark on the scale I82. I

After the proper adjustment of the scale has been obtained, the thumb screw 48 is tightened to secure the drum 44 to the sleeve 'll'to rotate in unison therewith. Then, as the paper isdrawn through'the machine by rotation of the crank I33, the drum .will be rotated one turn for each foot of paper passingover the rollers 31 and, of

course, overthe groove or slot H9 in the cutterbar 62, The finger I41 will ride along on-the surface of the scale member I52 adjacent the scale provided thereon until the shoulder I59 thereon is reached, whereupon said finger I41 will drop off the scale member I52 and into the opening I6I. When this takes place the tooth,-

or pawl, I33 constituting a stop member, will engage between two teeth of the ratchet wheel I31, halting rotation of the shaft I36 and of thesp'rocket wheel I35, thus 'stopping rotation of the sprocket wheel I30 and the paste roller 6| also..

The web 49 isfnow ready to be again out off by means of the usual hand tool run over the cutter bar 52 over the slot II9. After this has been done the paper is again'ready for measuring, if the proper match mark is in position; and if not, then the finger I41 can be lifted out of the opening Iii and the mechanism rotated sufficiently by means of the crank to bring the match mark in proper position. After this has been done the drum can be released from the shaft M and the ward as it approaches the table I60, which will cause the same to adhere to the table and fold thereon in a well known-manner. Said table I60 is suspended from the tubular member 53 by means of brackets I6I having hook-like portions I62 extending around the tubular member 53. Fingers I80. are provided to guide the web 49 from the roll I to the cutter bar 52.

The machine as above described, is suitable for cutting widths of wall paper ofany desired dimensions and for trimming the edges of rolls of paper, but inasmuch as most wall paper borders are printed four to the roll, that is, four borders arranged longitudinally beside each other lengthwise of the length of paper, additional cutter members are necessary to cut out all the borders at the same time. In order to provide for such an arrangement, the machine may be modified as shown in Figs. 12 and 13, in which a portion of the paste roller Si is shown and the backing roller 50 with the web of paper 49 in position thereon. .The cutter members for trimming the edges are mounted on the members I6 in the same manner as previously described,- and the intermediate cutter members on the levers ,90 are provided on the square bar II in the same manner as previously described.

' However, instead of providing the scale member "I0 on the bar 66 shown in Fig. 1, a rectangular bar 66', serving both as a mounting for the additionalcutter members and as a scale, may be provided, the same being i quick detachably mounted in upward extensions I63 on the side frame members 20. Any suitable form of quick detachable mounting can be used, a slot I 64 being shown for receiving the member 68', and thumb screws I66 being provided for securing the same in position in the slots I64. The cutter members 'table I60, the plate side of the "web is being downand the mountings therefor'are similar to those described in connection with the intermediate cutters, comprising a mounting member 82', similar to the member 62, upon which the lever I66 is rotatably mounted, the same having a rearward extension I61 having a thumb screw 94' mounted therein engaging with the finger 61' for holding the cutter members I66 in adjusted position and in cutting engagement with paper in a similar manner to the thumb screw 64, said extension I 61 engaging under the finger 91- when it is desired to hold said cutters out of cutting position. The lever I66 has a bifurcated lower end portion, in which the cutter member I 63 is rotatably mounted, said. cutter I66 being similar tothe cutter 9I previously described.-

In cutting borders, preferably, four of the cutters I66 are mounted on the rod-like member 68, in such positions as to align with the edge por-. tions of the border where cutting is to take place. These, together with the edge trimming cutters 6| and the intermediate cutters 9I', can beso arranged as to cut the four borders out-of the roll of paper at the same time. Itis preferred, instead 'of merely elevating the cutters I66 out of cutting position, to remove these entirely when the machine is not being used for cutting borders. This can be done by unscrewing the clamping screws I65, removing the bar 66' and sliding the cutters and the mountings therefor off the bar and then replacing the bar 66', using it merely as a scale. The cutter members I68 do not have to be provided with pointers to operate on the scale for cutting borders, as the borders can be out without the use, of a scale, but -if desired, pointers can be provided on the body portions of these cutter members to cooperate with the scale on the member 69'. The carriers 90 and I6 for the cutter members. are, however, provided with pointers similar to those previously described, but of different shape and length to cooperate with the scale on the member 66', which will be in a different position than the scale 10., these being indicated by the numerals I1 and 93' and corresponding in function to the pointers I1 and 93 Referring to Fig. 2 it will be noted that the table member I can be swung on the hook members I62, so that the brackets I6I will extend upwardly instead of downwardly from the tubular member 53 with the table in an inverted position,

serving as a cover for the mechanism, so as to ing the machine, the legs 25 bein of course, re-

make the samemore compact for carryingipur- A handle, or handles, of suitable character (not shown) may be provided on the bottom side of the member I60 for convenience in carrymoved when themachine is to be disassembled for carrying purposes. In order to make a carrying means out of the table I60, a pair of brackets I 69 are provided having snap hooks I10 thereon for engagement around the shaft 29 when the; wall paper roll 34 has been removed therefromi The size of the sprockets I30 and I35 and the gears of the'train comprising the gears I29, I23 and I I5, is, preferably, such that the paste roller 5| will have a very slightly greater surface speed than the backing roller 50 for the cutting mechanism, thus keeping the web 49 tensioned even if some slight slippage occurs between the paste covered surface of the roller BI and the surface of the web of paper 49. The cutter members 8i are freely rotatably mounted in the levers carrying the same, the mounting for all said rollers 6 I V 1 being. preferably, on ball bearings, as shown in Fig. 14 for the rotating cutter member 8i, said ball bearings being indicated by the numeral I'll in Fig. 14.
