To all whom it may concern: v

Be it known that I, JAMEs B. AUSTIN, a citizen of the United States, residing at Dolgeville,in the county of Fulton and State of New York, have invented certain new and useful Improvements in all-Paper Pasting and Trimming Machines, of which the following is a specification.

This invention relates to improvements in devices for pasting and trimming wall paper and it has for its primary object the provision of a machine of novel construction which embodies certain facilities whereby the work designated may be'performed more efficiently with a minimum amount of labor and with a material decreasing of the amount of time necessary in performing these operations. w

A coiirdinate object is to equip the'device with guiding means, which will insure accurate training of the paper over the paste applying roller, the guide means being adjustable to permit conformation towall paper of various widths.

A still further object. of this invention is the provision of an efficient pasting means consisting of a' paste tank,- a corrugated roller and a second roller which applies the paste to the paper; the two rollers so arranged and mounted, and the corrugated roller mounted in hearings in a novel manner, so that it will at all times furnish the necessary amount .of the paste to the roller without necessitating any adjustment whatsoever.

Among many other objects of this invention are: the provision of an indicator and measuring means whereby the desired amount of paper may be measured as the paste is being appliedthereto' and to equip the measuring meanswith a signaling device in order that the operator may be warned when the desired amount of paper has been pasted; to provide a novel attachment for the machine whereby the papermay be out after the-desired amount has been pasted and measured; to provide a carrierto carry the paper afterit has been cut and pasted to a position from which it may be conveniently applied to the walls of the room; and to provide novel and efficient means for automatically trimming the edges of the paper immediately'after the same has been pasted.

With the foregoing and other objects in view, this invention consists in such novel drawings, wherein like characters of reference designate like or corresponding parts throughout the several views, and in which,

Figure 1 is a longitudinal sectional view through the improved pasting and trimming means; Fig. 2 is an end view of the same; Fig. 3 is a top plan view; Fig. 4 is a detail fragmentary view of the device showing the indicator and measuring means; Fig. 5 is a detail view, showing the manner of mounting the bearings of the corrugated roller within the paste tank; Fig. 6 is a cross-sectional view through guiding members showing the manner of adjustment therefor; Fig. 7 is a detail cross-sectional view through a portion of the operating'mechanism; Fig. 8

is a detail perspectiveview of athumb-screw employed in the mounting of thejpaste roller upon the machine; Fig. 9 is a detail sectional view of the signaling device employed in connection withthe measuring apparatus; Fig. 10 is a side elevation of one of the trimming cutters; Fig. 11 is a top plan view of the trimming cutter; Fig. 12 is a sectional view of a modified form of the mounting of trimming cutters upon the frame of the device; Fig. 13 is a detail view of a part of the pasting mechanism showing parts thereof broken away. 1

Referring more particularly to the drawings, the numeral 1 designates the frame of the machine whichconsists of a rectangularshaped body having the cross pieces 2 se cured to the lower ends thereof to form braces and make the device more substantial. Wheels 3 are mounted upon the shafts 4:, which shaftsa're in turn mounted in brackets 5. The brackets 5 are secured to the under surface of the frame 1 by any suitable fastening means as at 6. The wheels form a means for conveniently moving or transporting the'machine from one place to another.

A bar or'roller 10 is revolubly mounted within the two longitudinal sides of the frame 1 near the rear end 11' thereof and is adapted to receive the roll of the wall paper which is shown in dotted lines in Fig. 1 and designated by the numeral 12. The wall paper, after leaving the roller 10, passes through a pair of guide-ways 13 which are preferably constructed of sheet metal such as tin or the like and have the two sides 14 and 15 thereof bent and extending parallel one with the other. These metallic guideways 13 are securely mounted, through the medium of the sides 15 thereof and any suitable fastening means, to plates 16. The plates 16 are preferably constructed of wood or some other light material.

As shown to advantage in Fig. 6, the plates 16 are mounted in the framel, and when engaged with the opposite sides of the latter, leave a space 17 between the proximate edges of the plates to permit relative adjustment of the same. A threaded bolt 18 depends from each of said plates, and passes through a slot 19 in a plate 20, said bolt being adapted for threaded engagement with thumb-nuts 21. These bolts 18 and the thumb-nuts 21 and the slots 19 form means for securely holding the two plates 16 in place after adjustment, and consequently the two guide members 13 so that they may conform to the various widths of wall paper and prevent the same from buckling or runmachine.

The plate 20 is slidably mounted between the sides of the frame 1 and is provided with a screw-threaded portion 22 which extends longitudinally therein from the side 23 of the same. A screw-threaded rod 24 is adjustably mounted through the screwthreaded portion 22 and engages in a screwthreaded cup 22, the latter depending from the plate 16, and forms means for adjusting the two plates 16 and the guiding members 13. The screw-threaded rod 24 extends through an aperture 26 in one of the longitudinal sides of the frame and the head 25 is on the exterior of the frame forming a convenient means for adjusting the guide-ways from the exterior of the frame 1. The guides 13 may be simultaneously adjusted, since the shank of the bolt 24 has right and left hand screw threads formed thereon, the threads of one pitch being engaged in the cup 22, while the threads of the opposite pitch are engaged through the screwthreaded portion 22 of the plate 20, thereby exerting pressure on the plate 20 for operating one of the guides, while the opposite guide will be actuated in view of the pressure exerted on the cup 22. A retaining plate 23 is carried by the frame 1 and is in engagement with the bolt 24 to permit rotary, but preventing longitudinal movement of the latter.

plates 30 which are hingedly connected to the upper edges of the longitudinal sides of the frame 1 as at 31. A hollow roller 32 is disposed between the two plates 30 and has a pintle extending from one of its ends which is seated within the bearing formed by the hollow portion 34 of the screwthreaded lug or thumb-screw 35. The upper portion of the inner end of the thumb-screw 35 is cut away as is shown at 36. When the thumb-screw 35 is turned so that the cut-out portion 36 is upward, the pintle may be disengaged from the bearing 34 consequently permitting the removal of the roller 32 from its place between the two upstanding plates 30; but when the member 35 is turned, by means of the handle 37 thereof so that the cut-out portion is facing downwardly, the pintle will be held from displacement since the turning of the member 35 causes it to be fed I inwardly, thereby preventing its displacement and incidentally the displacement of the pintle which is carriedtherein. The opposite end of the drum 32 from that upon which the pintle is arranged, has a stubshaft 38 associated therewith which is engaged with a crank handle 39.

Flat springs 42 which have bearings 43 formed intermediate their ends are mounted, through the medium of the bearings 43 upon pins 44 which are mounted one.

in each of the upstanding plates 30. The springs 42 have a roller 45 mounted upon their lower ends and in such position as to engage the roller 32 at all times during the rotation of the latter. The upper ends of the springs 42 engage the crank portions 46 of a rod 47 which extends transversely across the frame being mounted in each of the upstanding plates 30 and having a handle por- 1 tion 48 formed upon one end and screwthreads upon the other end which are engaged by a nut 49. The turning of the rod 47 by means of the handle 48 and thus the raising of the crank portion 46 upwardly will decrease the tension with which the roller 45 bears against the roller 32 and pen mit of a thicker grade of wall paper passing between the two rollers. In this manner the rollers are adjusted to accommodate the va- 1 vided with a groove 50 which forms a surface upon which a belt 51 travels. The belt 51 passes about the roller 45 up over a roller 52 which is mounted in suitable bearings in the upper ends of the upstanding plates 30. This roller 52 has a plurality of strips of any suitable material such as cheese-cloth or the like passing therealoout and about a roller 54. The roller 54 is rotatably mounted upon the upper ends of a pair of bars 55 which are adjustably mounted by means of the pivoting pin 56 and the pins 57 thereof in the longitudinal sides of the frame 1. The pins 57 in the lower ends of the bars 55 travel in arcuate grooves 58 which are formed in the sides of the frame 1 to permit of the movement of the bars 55 longitudinally of the frame. v

A paste tank 60 which is substantially U-shaped in cross section is secured to the upstanding plates 30 directly beneath the roller 32 and has a roller 61 which has its outer surface corrugated as is shown at 62 revolubly mounted therein. The ends of the roller 61 have stub-shafts 63 formed thereupon. These stub-shafts 63 are seated within bearings 64 which are formed in rectangular blocks 65. The blocks 65 are mounted between guide-ways 66 which are secured to the ends of the tank 60 in any suitable manner as at 67 having their sides 68 bent at right angles to the sides which are secured to the ends of the tank and forming guide-ways for the blocks 65. Disposed between the sides 68 and engaging the under surface of the blocks 65 is an expanding coil spring 69 which tends to hold the roller 61 at all times in engagement with the roller 32. By corrugating the roller 61, it is seen that the paste is conveyed from the tank 60 to the roller 32, thereby insuring the efficient application of the paste to the wall paper when the latter is passed between the rollers 32 and 15.

Mounted in any suitable manner between the upstanding members 30 is a rectangular bar 70 which has a plurality of wires 71 secured thereto and extending upwardly therefrom. The wires 71 are bent substantially at right angles, one portion thereof to the other as is shown at 72 and the ends 73 of the same engage the surface of the roller 32 so as to receive the wall paper after the same has been pasted as it passes over the roller 32. When the wall paper is engaged by the ends of the wires 71 it passes downwardly over the same and is in turn engaged or re ceived by the curved ends 74 of the plurality of rods 75 which have their ends 76 secured to a roller 77. The roller 77 is rotatably mounted in suitable bearings upon the frame 1 and has a crank handle7 8 attached to one end thereof for actuating the same. The wires 75, after being curved over the roller 76, extend downwardly and are wound about a cross rod 79 which tends to reinforce them in order that they may perform their fuctions in an eflicient and practical manner.

The'paper, after leaving the roller 32 and the wires '71 immediately before it is receivedby the curved ends 74 of the rods 75, passes over a knife 80. which is carried by a supporting bar 80. The knife 80 and the supporting member 80 are securely con nected to the bars 84, which bars are in turn connected to a lever 81,'as at 85. The lever 81 is pivoted at 83 to one of the upstanding plates 30 and has a handle 82 formed upon its upper free end. When the lever 81 is moved upon its pivotal point, through the medium of the handle 82, the knife 80 will be raised upward, when the handle portion of the lever is moved downward, and brought into engagement with the paper which has been pasted. When it is desired to cut the pasted paper the knife 80 is raised upward so as to engage the paper and any suitable means such as a roller or the like is passed over the upper surface of the paper and forcing the same downward upon the edge of the knife 80 will cause the paper to be cut or severed.

Roller knives which trim the edges of the wall paper are rotatably mounted in bearings 91 which are in turn secured to the bearings 92 which are mounted upon the shafts 93. The shafts 93 have slots 94 cut therein which extend the entire length and which receive the ends of a coil spring 95 which is wound about the shaft and passes over the bearing 92 as is clearly illustrated in Fig. 11 of the drawings. The portion 96 of the spring 95 which is upon one side of the bearing 92 is wound about the shaft 93 in one direction while the portion 97 on the opposite side of the bearings 92 is wound in the opposite direction. This respective winding of the ends of the spring imparts force to the portion 98 of the same which engages the member 92 and causes the cutting rollers 90 to always be in engagement with the surface of the roller 32 or in engagement with the paper as the same is passing over the rollers 32. The bearings 92 and consequently the cutting rollers 90 are adjustably mounted upon the shafts 93 by means of thumb-screws 99 which pass through screw-threaded apertures in the bearings 92 and engage the shaft 93. The outer ends of the shafts 93 are square in cross-section and have ratchets 100 mounted thereupon. The teeth of the ratchets 100 are engaged by the pawls 101 mounted upon the outer surface of the upstanding plates 30. These pawls 101 tend to hold the spring 95 under tension when the same has been wound through the .medium of the square end of the shaft 93 which protrudes or extends through the upstanding plates 30.

In Fig. 12 of the drawings a modified form of the manner of mounting the shafts 93 is shown, the same having a coil spring 95 which serves a purpose similar to the coil springs 95 mounted thereabout and in a recess 96 within the sides of the upstanding plates 30, otherwise this mounting is identical with that shown in Figs. 10 and 11.

The stub-shaft 38 has a collar 105 mounted thereabout which has practically one 7 of the drawings. The disk 107 is fixedly mounted upon the angular shaft 108 which is engaged within one of the upstanding plates 30 and which is bent as is clearly shown in Fig. 9 of the drawings; This disk 107 is mounted immediately above a scale on one of the plates 30 which has a plurality of serially-arranged holes 109 formed about the outer edge of the same and spaced directly opposite the lines of the scale which designates the number of feet of paper which has been passed over the roller 32 or the number of feet of paper which has been pasted. A rod 110 has its inner end wound about and secured to the angular shaft 108 and its outer end extending outwardly so as to engage a small plug (not shown) which is inserted into the holes 109. The disk 107 is rotated through contact with the shaft 38, and when it has been sufficiently rotated to cause the outer end of the rod 110 to engage with a pin placed in one of the holes 109 for designating the amount of paper to be pasted, further rotation of the disk will cause the rod to be flexed rearwardly, continued rotation of the crank causing a projection 111 which extends outwardly from the rod 110 to strike the bell 112, since the rod is released immediately after passing the plug with which it engaged in view of its inherent resiliency, thereby announcing that the desired amount of paper has been pasted.

. This ringing of the bell will warn the operator that the desired amount of paper has been pasted. A coil spring 113 is connected to the outer end of the shaft 108 and to the collar 105. When the desired amount of paper has been wound from the roll 12 and original position or to fly back to the,

original starting point, while the spring 113 will also pull or draw the disk 107 back into engagement with the shaft 38, thus the machine will be ready for another strip of paper to be pasted and cut.

The cutting roller 11 1 which is constructed identical with the cutting rollers 90 is mounted upon a shaft 115 which is mounted in bearings in the two upstanding members 30. One of the bearings in which the shaft 115 is mounted is identical with the bearings of the ends of the shafts 93 upon which the rollers 90 are mounted and the cutting roller 114 is centrally mounted between the two upstanding plates 30 so that it will split the Wall paper directly in the center when this operation is desired.

U-shaped members 116 are pivoted to the I upstanding members 30 at 117 and are engaged by catches 118 upon the frame 1 holding the upstanding plates 30 rigidly in an upward position. WVhen it is desired to fold the upstanding plates 30 inwardly so as to make the machine more compact in form,

the catches 118 are released and the U'shaped members moved out of engagement with the lower edges of the frame 1. This will allow the upstanding plates 30 to be folded inwardly by means of the hinges 31.

The wall paper is first unrolled from the roll 12 and passing through the guide-ways 13, the end of the same is inserted between the two rollers 32 and 45. The crank handle 39 is then operated, which operates the roller 32, thus causing the rotation of the rollers 45 and 61 which in turn operates the other parts of the mechanism which are con nected thereto as'has been heretofore set forth. The rolling of the corrugated roller 61 will supply the roller 32 with paste which will in turn apply the same to thewall paper as it passes thereover and also as the wall paper is passing over the roller 32 the cutting rollers 90 will engage the outer edges of the same cutting the strips from 03 the edges as is necessary. The paper passing onward over the rollers and having the strips cut from the edges of the same will pass downwardly to be received by the series of rods 75. After a certain amount of the paper has been pasted and passed from the roller 32 and received by the series of rods 75, the crank handle 78 is operated: this will raise the series of rods to permit feeding the wall paper to the carriers 53. Thecontinuous rotation ofthe crank handle 39 and the pasting of the paper will also'impart rotary motion to the roller 52 upon which the carice riers 53 are mounted. This rotation of the roller 52 will impart motion to the carriers 53 and cause them to carry the paper to a position from which it may be conveniently put upon the wallsof a room.
