6 Claims. (o1. 91-14) The invention relates to a machine for use in the hanging of paper and adapted to apply paste to the back face of the paper as the paper is unrolled, trim the edges, and measure the proper length for cutting off each strip so that the paper may be easily removed and applied toside walls or ceiling as desired. I

The object of the invention is toprovide a light and compact machine which can be easily dismantled for transportation, and which performs all of the operations necessary to unroll the paper, trim the edges, apply an even coat of paste of any desired thickness to the back face of the paper and measure the same the proper length for cutting off, all by the manual operation of a single crank. v

A further object is to provide a machine-of the character referred to which may be easily and readily opened up to give full access to the interior for installing the paper and filling the paste trough or pan.

Another object is to provide a machine of this character in which the paste is evenly distributed over the back face of the paper by meansof a spirally grooved roller and forced toward the center of the paper, preventing any paste from squeezing out at the end of the rolland getting on the pattern of the paper.

snu another object of the invention is the provision of such a paste applying roller or cylinder, which is compactly located and arranged to revolve in the opposite direction to the movement of the paper, so as to' insure a proper amount of paste being applied to the paper.

Another object is to rotatably mount the paste control roller in eccentric bearings provided with a lever for adjusting the position of the roller for applying a light or heavy coating of paste upon the paper, as desired.

A further object is to provide amachine of this character in which the working parts may be quickly and easily dismantled or knocked down.

A still further object is the provision of a novel and simple device for measuring the proper length of the paper for cutting off.

Still another object is the provision of means for splitting a strip of paper to any desired width as the same is unrolled and pasted.

A further object is the provision of means for controlling the roll of paper in the machine, comprising rod 'or shaft slidably mounted through the frame, and located through a spaced pair of disk flanges, one flange being fixed to the adjacent frame member, and the other flange being ;eccentric bearing for adjusting movable toward and from the opposite frame member to facilitate installing the paper roll, the movable flange being controlled from the outside of the frame by a spring loaded'bar which is operated by a lever, the bar placing tension upon theend of the paper roll.

A still further object is to provide a machine of this character having a carrier or conveyor for drawing thepaper out of the machinabeing. geared to run slightly faster than the rolls, so

as to keep the paper under tension.

Still another object is to provide means for adjusting this carrier from a vertical to'nearly a horizontal position for measuring different lengths of paper as may be required;

The above objects together with others which will be apparent from the drawings and follow-" ing description or which may be later referred to, may be attained by constructing the improved paper hanging machine in the manner illustrated in the accompanying drawings in which Figure 1 is a side elevation of the improved machine showing the same in operation;

frames l4 as at I3 and connected at their upper ends by a cross piece 55, is adapted to engage over the forward ends of the hinged frame members I4a.

A pair of rearwardly extending metal arms is connected to the L-shaped arms 48 and pro land 3.

A pair of links 54 is pivoted as at 55 to the arms 5! and at their ends they are connected by a cross bar 56 provided with a hand grip 51 I the pivots.

by means of which the links may be swung upon The forward edge of this cross bar comprises 8 a straight edge 58 and a hold-down roller 53 is A lever I03 is pivoted upon a bracket I04, fixed to the adjacent side of the frame, and provided 'with a depending lug I05 contacting the inner; surface of the spring arm 35, a hand knob I06 being provided upon 'said lever for pulling the same outward to move the flange 34 outward so as to relieve the tension upon the paper roll and facilitate the removal and replacing of paper:

rolls, when the rod 33 is withdrawn.

The paper is unrolled fromsaid rod 33 and as indicated atfP is drawn over the top of the paste roll 30 so as to apply paste from the trough to the back or under surface of the paper which then passes around a roll36 fixed upon a shaft 31 journaled in bearings 38 located through the hinged side frames '45., a sprocket 39 being fixed upon one end of said shaft for driving the roll 36 as will be later described. 1

a A grooved roller 40, preferably provided with; oppositely disposed spiral grooves 41 extending from the center toward eachend, is fixed upon a shaft 42 journaled ineccentric bearings 43 rotatably mounted through openings 44 in the side framesxl-l and provided'with levers 45 foradjustingthe bearings in order to adjust the "positionof the'roll 40 toward or from the roll 36 so as to evenly spread the paste in a film or coat-' 3 ing of any desired 1 thickness entirely across the back or under surface of the wall paper.

The side frames l4 have their upper-forward 1 portions-cut out as at 46 to receive the hinged side 3 frame members I43, which are connected togather at their upper rear corners as by the cross bar, 41, hinges 41" connecting said A hinged frame comprising a pair of inverted cross bar to journaled between the links 54. a

For the purpose of trimming the usual margin from. each side of the wall paper a pair of adjustable disk knives 60 is provided, one knife being adapted to trim each margin.

These disk knives are mounted upon blocks 6! 66 may be provided, being carried upon a block- 61 slidablyfmounted upon the rod 49 and. providedwith a springarm 68 having an angular upper end 6 9 terminating in thedownturned lip 70 adapted to engage over the ledge 1| upon the cross piece 50 and provided .with a knob 12 for operating the same. Y

,A relatively narrow roller 13" may be carried in abracket 74- supported upon the cross piece 50,; .said roller being adapted to hold the strip of wall; paper in contact with the upper side of the olle i -v Y I A conveyor is mounted upon the machine and comprises a pair'gof side frame members 15 between the lower ends of which is journaled a roller 16 mounted in open bearings 11 fixed 'to' the upperedges of the side frames I4, curved bars 13 being hingedly mounted upon said bearings andadapted to be, normally located in the position shown in Figs, 1, 3 and 4'for retaining the roller in'the bearings.

A-sprocket 19 is fixed upon the roller 76 and connected by a sprocket chain 80 with the sprocket 39 upon the roller 36, A hand crank sprocket 19 for manually the upper portion of the side. frames 15, by anadjustable connection indicated generally at 81, the lower end of the U-shaped rod being adapted to be received by thelugs. 83, at the lower rear corners ofv the side frames 14.0! against the stop pins 89' at the upperfrear corners of .said side frames.

A U-shaped bracket 90 is attached to the. upper end of the conveyor'by means of. brackets 9| and provided in each leg with a series of notches 92 adapted to receive opposite ends of a rod 93 to which one end of the paper strip may be con-' nected as at 94.

For the purpose of matching the strips a de-. pending rod 95 may be connected to one of the brackets. 9| as by a screw 96 and provided with adjustable pointers 91..

A weighted spool 98 is provided to cooperate with the pointers 91 to measure the length of a strip as will be later described.

A metal plate I 01 may' be fixed transversely across the conveyor beneath the straight edge 58' to that by means of a sharp knife or the like the paper strip may be cut off at this point.

For the purpose of rotating the paste roll 30 in the direction of the arrow shown in Fig. 3,v sprockets I08 and I09 are fixed upon the shafts of the conveyor roller 16 and the paste roller 39 respectively, and are connected by a chain III].

In the operation of the machine to paste, trim and measure wall paper, a roll of paper is placed upon the spool33, as indicated at 34.

Paste is placed in the trough 24 and the end of the roll of wall paper is placed, with the back down over the paste roller 30, between the roller 36 and the grooved roller 40 and then under the roller 13 and hold-down roller 59 and onto the endless belt 85 of the conveyor.

The crank 8| is then rotated in a clockwise direction, rotating the conveyor belt 85 so that the upper side thereof travels upward, rotating the paste roll in clockwise direction so as to apply paste to the back of the strip of wall paper and rotating the roll 36 in a clockwise direction so as to feed the strip of paper upward to the conveyor.

It should be understood that unless it is desired to split the strip of paper, the disk cutter 66 is moved away from the roll 36 by disengaging the spring arm 68 from the cross piece 50.

It should also be understood that the margin trimming disk cutters 60 are properly positioned to trim the margins from the strip of wall paper.

The frame 15 of the carrier, or conveyor is graduated, preferably up to forty inches, for measuring short strips of paper, but for measuring and matching longer strips for side walls and ceiling, the correct length may be obtained by raising or lowering the carrier to the desired adjustment, so that the required length of strip reaches the floor from the cutting-off point. For instance, if an eight foot length is required, for side walls, the carrier is so adjusted that when the end of the paper reaches the floor the paper may be cut oil at the straight edge 58, producing a strip eight feet along. By raising or lowering the outer end of the carrier, strips of greater or less length may be accurately m'easured.

When strips of much greater length are required, the folder is used, as shown in Fig. 1. The paper is then run about six inches beyond the end of the carrier and a rod 93 is inserted under the paper and placed in the outermost notch 92, and the end of the paper is press-ed over the rod and against the pasted surface of the strip, as indicated at 94, and the weighted roll 98 is placed on top of the paper, and the paper is run through the machine until the weighted roll reaches the floor, as shown in Fig.

1. This makes a singlefold, by which strips of from eleven to fourteen feet may be measured.

To produce longer strips two or more folds may be used, it being possible to accurately measure up to the entire length'of a roll, if desired. For a double fold, when the paper reaches the position shown in Fig. 1, a second rod 93 is placedbeneath the left hand side' 01 the depending loop .of paper and pressed into the next adjacent notch 92 in the folder arms, and the weighted roll 98 is placed on top of the paper, between the end of the carrier and said rod, and the machine is operated as above described. Four such folds may be made, folding the entire roll of paper.

The matching of the paper is accomplished by means of the depending rod 95 and the pair of pointers 91'. These pointers may be of different colors for convenience of the operator, one generally being green and the other red. For a straight across match only one pointer is used, but for a drop match the two pointers are used alternately.

Assuming that an eight foot strip is required, the machine should be operated to run out eight feet of paper as above described; then if the place on the margin where it says Join is at the cutting-off point 56, the machine is set for a straight across match by locating the green pointer to register with the place marked Join. A

For a drop match pattern the other, or red pointer is then set midway between the points marked Join, and each pointer is used alternately.

From the above it will be obvious that a very simple, efiicient and inexpensive apparatus is provided for quickly, easily and accurately pasting, trimming and measuring strips of wall paper for hanging, and it will be seen that the machine may be easily and quickly dismantled for transporting or storing the same and may be easily assembled and placed in condition for op eration.
