WALL-PAPER TRIMMING AND PASTING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 650,215, dated May 22,1900.

Application filed July 24, 1899. Serial No. 724,898. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, JOHN T. AVERY, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improve ments in VVall-Paper Pasting and Trimming Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a machine for applying paste to wall-paper and for trimming the edges thereof preliminary to affixing the paper to the walls or ceiling of a room.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a top or plan view of my machine. Fig. II is an enlarged detail View showing two of the adjustable rotary cutters. Fig. III is an enlarged detail sectional view taken on the line III III, Fig. 1, looking in the direc-' tion indicated by the arrow crossing said line. Fig. III is a section taken on the line III" III, Fig. III, looking in the direction indicated by the arrow crossing said line. Fig. IV is a sectional view taken on line IV IV, Fig. I, looking in the direction indicated by the arrow crossing said line. Fig. V is a View in side elevation. Fig. VI is a detail View of the delivery-roller and adjustable slitting knife adapted to operate thereagainst. Fig. VII is a vertical sectional view taken on line VII VII, Fig. IV, looking in the direction indicated by the arrow crossing said line.

- 1 designates the frame of the machine, containing a paste-receiving box 2, the bottom of which is preferably inclined, so that the paste will run to the forward end of the box. Mounted in the side walls of the frame 1 is a shaft 3, on which a roller 4 is carried and which rotates in the direction indicated by the arrow thereon in Fig. IV. ,One end of the shaft 3 extends through one side of the frame 1 and is journaled to a bearing-screw 3, mounted in a bracket 6, located exterior of the frame 1'. The opposite end of the shaft 3 is journaled to a similar bearing-screw 3", mounted in the other side of the frame 1.

On the roller 4 is a covering 5, adapted to travel in the paste contained by the box 2 The covering 5 maybe of any suitable absorb ent material, such as cloth, or a cylindrical brush may be applied to the circumference of the roller;

7 designates arms located over the sides of the frame 1 and connected by tie-rods 8 and movably secured to the said sides by hinges 9. The arms 7 carry a pressure-roller 10, adapted to rotate in the direction of the arrow associated therewith to bear upon the wall-paper (indicated byadotted line extending through the machine) and hold it to the pasting-roller 4. when the said pressure-roller is in the lowered position shown by full lines in Fig. IV. The shaft of the roller 10 is mounted in bearing-screws 10, extending through the arms '7. When the pressureroller is not in use, it may be elevated into the position shown by dotted lines, Fig. IV. The arms 7 are set back on the sides of the frame 1, so that the roller 10 is not directly over the center of the roller 4, which position of the roller 10 causes the wall-paper to be held against the periphery of the roller 4 a greater distance than it would were the roller 10 directly over the roller 4.

11 is a shaft journaled at one end in one side of the frame 1, extending through the other side of the frame 1 and journaled at the otherend in the bracket 6. On one end of the shaft 11 is a tight tape-drum 12. (See Fig. III.) Wound upon the drum is a tape 13, provided with a handhold let. By pulling on the tape 13 the shaft 11 is revolved, and to wind up the tape when released the shaft is surrounded byacoiled spring 15, one end of which is made fast at 16 to one side of the frame 1, the other end being secured at 17 to a ratchet-wheel 18, carried by the shaft. If it is desired to hold the shaft from turning back when the tape has been pulled out, this may be done by pivoting pawls, 19 to a side of the frame 1, so as to engage the ratchet-wheel when desired, as shown in Figs. III and III. On a sleeve 20, that is secured to a side of the frame and which fits over the shaft 11 next to the drum 12, is a loose pulley 21, having an inner groove 22 to receive a belt 23, that passes over a pulley 24 on a shaft 3 of the paste-roller, so, that thepasteroller is revolved when the drum is turned by pullingon the tape 13, the pulley 21 having a ratchet21 and a spring-pawl connection 25 (see dotted lines, Fig. V) with the When the tape 13 is being wound up, the pawl 25 slips over its ratchet 21. The pulley21 hasfa second or outer reets.

26 to receive a belt 27, that drives the cutters,

hereinafter referred to. Secured to the inner. faceof the pulley 21 is a ratchet-wheel28,

engaged by a pawl 29, pivoted to the frame 1. (See Fig. V.) V The pulley 21-is thus held.

I When thefpaperis. wound. onto theroller 30, as explained, (the roller 30 turning in the directionl of the arrow associated therewith',) its freer-end is grasped and drawn over'the idler; 34and therefrom. onto the pasting-roller 4, passing underthe pressure-roller 10, itbeing understood that the reverse side of the paper is always presented downmost to the pasting-roller. As the paper leaves the past-v ingrrollerit passesv over a series of scrapers 37., seatedsin: the sides of the frame 1, which also-form-the side walls of thepaste-box and; extending" thereacross,.. said scrapers being designed to remove the surplus. paste from thempaper.

Each cutter 44 is backed by a coiled spring 45,held in place by a set-collar 46. Immediately beneath the shaft 38 is a similar shaft 47, the ends of which are journaled in bearing-screws 48. On the shaft 47 is a pulley 49, that also receives the belt 27,, as shownin Fig. V. On the shaft 47 are circular cutters 51, that co- '.operate with the'cutters 44, which are also loosely keyed to the carrying-shaft. The cutters. 51 are backed by springs 52, held forward by set-collars 53. The cutters turn in the direction of the arrows shown associated therewith in Fig. IV. The arrangement of these cutters is clearly illustrated in Fig. II. "As the paper leaves the scrapers 37 'it is carried between the circular cutters 44 and 51, which are held together by the springs 45 and 52, and the trimming of the paper is thereby accon1plished-. If it is desired to trim but one'edge of the paper, the cutters 44 and 51 at the oppositeside of the machine Lmay be moved tothe ends of thejsh'afts 38 and 47 by releasing the set-screws inthfe col- 'lars 46 and 53.

On leaving the cuttersthe paperpassesto l shaft of which is mounted in bearing-screws E55. The delivery-roller-54 is provided with guide-flanges56, adapted to direct the course gof the paper as it passes under said: roller.

gT-he paper is taken'i'ro'm beneath thefdelivgover idler-rollers-57, journaled onbearingiscrews 58, seated in standards 59,, that are ;connected by tie-rods 60 and supported-from ;the frame of the machine.

When, however, the paper is to :ting-knife is not in use, it. may be loweredby- It will therefore be seen thatthe slitting-knife ported'on a spindle (not shown) is placed close to the roller 30. Theoperator then takes the end of the paper and places it face inward under the clamps on the roller and turns the roller. This the operator does by simply putting the hands on the roller and turning it. It of course turns very easily, as there is no pull on the paper. After the paper has been wound onto the roller 30 the operator takes hold of the end of the paper and passes it over the roller 34 and on through the machine, as shown by dotted lines. As it passes through it comes in contact with the roller 4, which causes it to-be pasted. As it comes out of the machine itis trim med, and the operator places it against the wall. Supposing the machine to be resting on the floor, he would conduct the end of the paper to the wall at the ceiling and with a brush, as usual, cause the paper to be smoothed on the wall down to the mopboard. The operator would then cut it 01f at the mop-board and take the end up to the ceiling again and repeat the operation. While the paper is being pulled through the machine by the left hand, the handhold 14: of the tape-coil is grasped by the right hand to rorate the tight pulley 11. The pulley 11 is connected up with the paste-roller and cutters to paste and trim the papers simultaneously with the passage of the paper through the machine. The rotating of the tight pulley 11 winds up the spring on the power-shaft to Wind up the tape each time it is unwound.
