TRIMMER, AND FOLD.

Application filed August 2, 1828. Serial No. 655,889.

To all whom it may concern:

' ,Be it-known that I, PALACE BUTLER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Wall-Paper Pasters Trimmers, and Folders, of which the following is a specification. The object of this invention is to provide a machine for applying paste to the proper surface of wall paper, trimming one or both edges of the paper and folding and pilin it like it is usuall folded and piled W en pasted by hand or the operation of applying the pasted paper to a wall or ceiling.

A further object of the invention is to provide a machine capable of adjustment to paste and trim wall paper of varying widths fed into the machine from a roll, and to produce such a machine 11y porta le that it may be easily carried from place to place wherever the handling of paper is to be carried on; that will not wrinkle, tear or crease the aper orsmear paste upon the face or gured surface thereof.

I accomplish the above and many other minor objects which will hereinafter appear, by the mechanism illustrated in the accompanying drawings, in which- Fig. 1, is an elevationof that side of the machine from which the pasted and trimmed paper discharges.- Fig. 2, is an elevation of the crank-end of the machine, showing in dotted lines how the front section of the folded paper table may be folded upwardly and backwardly for the purpose of compacting the machine when it is to be carried around. Fig. 3, is an elevation looking at the opposite end from that shown in Fig. 2. Fig. 4 is a top plan view. Fig. 5, is a cross section of all but the legs, on the line 5- 5 of Fig. 4. Fig. 6, is a detail in perspective of a ortion of the table-track on which the pasted paper is folded and stacked, showing a hinged and folding end of said track. Fig. 7 is a side elevation of the plate that guides the universal shaft for moving the folding table. Fig. 8, is a convenient handling in that is simple, conven ient, com act, durable, efficient, and so readperspective view of the scraper for removing paste excess, the thickness of the blade belng exaggerated to more clearly show its corrugations, and Fig. 9 is a perspective view of the device for measurln the lengths of strips to be .cut oil.

Like characters of reference indicate like parts in the several views of the drawings.

relatively fixed base or table 10 supports the operative mechanism of my invention and for convenience the table is supported upon four folding legs 11. These are crossed in pairs as shownand the legs-of each pair are pivoted together at their intersections. They are held in crossed relation to each other by; two-bar brace 12.v The outer ends of the bars are ivoted to the respective legs .and their inner ends are lapped and also pivoted together. A stop 13 on' one allows the bars to break in one direction only. (See Figs. 2 and 3.) I

The legs of each pair, sloping in the same direction, are connected b a two-piece bar 14, pivoted together at 15. A stop 16 on one allows the bars to break only'in an upward direction for folding, and in use, thisispre vented by a diagonal brace 17 attached at one end to pivot 15, and havinga hook-slot at the other to hook over a pin 18 in one of the legs. By releasing the brace bars the bars and legs may be compactly folded for carrying from place to place.

Fixed to the top of table 10, are four standards 19, that support a paste-holding box 20, here shown as the segment of a 'cylin In its ends 21 oblique grooves 22 are formed to receive the end trunnions 23 of a cylinder 24. The lower portion of the cylinder is submerged in the paste and its function, when rotated, is to carry an excess of paste up and apply it to the wall paper. The grooves 22 allow for the easy removal of the cylinder whenit and the interior of the paste-box are to be cleaned. The box 20 has a clean out opening closed while the machine is in use, by a screw-cap 25.

Closing the grooves 22, are angle-bars 26, retained by pins 27, one-of which has a wing-nut 28, the removal of which allows the bars to be lifted off for cleansing purposes. MW

- member connecting whole, longitudinally the The vertical flanges of bars 26 support a rod 29,"'-on which a U-sha ed frame swings. e e stems of the frame parts which pass through a is in two-lapped 30, and. are held by a setpair of 100 s 30, screw 31. justed in width to receive rolls of wall paper of different dimensions between the stems. The stems of the U-shaped frame support a rod 32 on which the roll '33 of wall paper is mounted. The frame is adjustable as a the rod, a screw-t readed portion 34 of which, (see Fig. 4) passes through a nut 35 fixed to the ame. The rod 29 is rotated by a hand-wheel 36. A bar 37, much longer than the stems of the frame, is fixed to one of the stems to even the pa er against, so the paper will feed througi the machine properly. The i'ollof paper bears by gravity against the paste suppl mg cylinder 24, paper' being unrolle and threaded through the machine as shown in Fig. 5. It passes from the cylinder 24 to and over a roller 38, mounted ona shaft 39, the bearings for which are held closed and are re.- leased b the angle-bars 26. On an extended endof aft 39 IS a hand-crank 40, by which power is manually applied to operate the machine. The shaft 39 'is the master shaft from which all of the other operative parts are driven. A sprocket-wheel 41 on 39 is connected by a link-belt with a larger wheel 42 on a trunnion of cylinder 24.

Su ported by suitable standards that are attac ed to the angle-bars 26, is a bar 43, here shown approximately ovoid in cross section, to the tapering side of which the ends of apair of strap springs 44 are fastened. These pass under and around the bar and terminate above the roller 38 with bifurcations in which circular cutters 45 are rotatably mounted.

bolt 46 from the secured end of each spring 44, passes through the spring-body above it to a rocking cam 47, an by proper manipulation of the cam the spring may be released to raise the cutters away from the wall paper or compressed to bring them into cutting contact. The cutters are adjustable longitudinally of the bar 43 on the latter by releasing their cams which loosens the spring so they can be slid to desired position on the bar. This adjustment is to cut the edges of the wall paper at the right places.

The above described cam-adjustment of the cutters provides means for releasing one of the cutters when it is not desired to cut the edge of thepaper on that side of the roll. The cams also afford individual cutting adjustment, but the principal cutting pressure is secured by an arm 85 hinged to the end of bar 43 to rock it, which arm is held to a given position of the cutters by allows the frame to be ad-- of rod 29 by rotating.

' its greater shaft paper from adhering ma am an engagement with a toothed-rack 86, on

the end of the paste-box.

Additional cutters may is desired to trim the margins and also to cut the piece into narrower strips, at one operation.

The members 48, of the standards, supporting bar 43 are turved obliquely and so positioned 5, as to' properly support the trunnions of a roller 49 bearing by gravity against the printed face of the wall paper passing over the roller 38. The face of the roller may be plain, but it will preferably be corrugated spirally as shown in Fig. 1,. to even the paste on the pasted side of the wall paper passing between the roller 49 andthe roller 38, and more particularly, to feed the paper through the machine. On the end of the shaft 39 opposite the hand crank 40, is mounted a spur gear 51 having a diameter approximating that of the roller 38. The roller 49 has a spurgear 50 mounted on end to mesh with the gear 51 and of a diameter considerably lessthan that of the gear 51, such that in turning the roller 38, the roller 49 is thereby ositively driven through the ears 51 and 50 at a speed than t 1e speed of the roller 38. A scraper 52 is attached to the edge of the paste-box below roller 39 to remove all excess of paste from the latter; but to leave a. desired minimum on roller 39, I provide a series of corrugations or grooves 53 in the contacting edge of the scraper, but these may be omitted. Metal clips 54 of S-shape be used where it' as shown in Figs. 1, 2, 3 and the paste excess removed by the scraper.

olded The pasted paper'has now to be and stacked for convenient handling by the paper hanger, and to accomplish this I allow it to drop from roller 39 upon a platform 55 below, having a reciprocating travel, and to kee the pasted side of the to the side of the passes, I form the ribs 56' (see Fig. 1) on the side of the box.

The platform 55 has underside battens 56 with plates 57- attached to their undersides and pro'ectin outwardly and laterally.

The plates side on metal tracks 58, having flanges 59 turned over the extended edges of plates 57 to prevent derailing of the platform.

Supported by a hanger 60 from the middle of the track is a rack-bar 61 with cylindrical teeth which are engaged by a pinion 62 mounted on the end of a shaft 63 which is connected by a universal joint 64 (see Fig. 1) with a stationary shaft 65 bearpaste-box as it ing a sprocket-wheel 66 that is driven by a -belt 67 from shaft 39.

By the-above construction the shaft 63 and its pinion 62 have freedom of movement that ermits the one side the rack to the other "when it reaches an end of the rack, and thereby reverse the direction of travel of the rack and consequently of the paper folding platform to which it is attached. Movement of shaft 63 is limited by. a suitable cam-opening 68 in a fixed plate 69, and the return of the table by the pinion passing around the ends of the rack is insured by suitable stops, such asthe block 70 at one end and a bar or finger 71 at the other which finger cona wheel 76 on the master tacts with the downwardly bent end of a plate 72. The'plate 72 is pivoted to the platform and its bent end projects down through a curved slot in the table which slot is long enough to allow the plate and its bent end to swing out of the ath of finger 71, when removal of the plat orm from the machine is desired.

It is necessary often to change the position of the platform relative to the pasted paper coming to it, and this is accomplished by disengaging a dog 74, carried 'bythe shaft 39, from a toothed-wheel 75 on the hub'of s rocket-wheel 76. When the dog is out o engagement with wheel 75, the platform drive mechanism is released, and

- the platform can be moved to any required position and connected up again by re engaging the dog.

or very wide paper the platform is widened by plate extensions 90, having clamp plates 91 to engage the edge of the platform.

The track for the support of the reciprocating platform is made longer than the width of the paste-box above, by hinged bracket extensions 92. These have lower diagonal brace members 93 which, with the track portion above, are hinged to the ends of the main tracks and fixed brackets 94, by vertical pins 95. The hinge openings through members 93 are slotted longitudinally for a swinging movement of the bracket vertically to seat and unseat a locking-lug of the end of the brace, in a hole in bracket 94. The .above construction permits ofthe folding of brackets 92.

I have next to describe a means for measuring the lengths of wall paper strips, and for stopping the machine when the length it has been set for is measured.

A shaft 78 has a loose wheel 79 driven by a worm on a shaft 80, on which *is a sprocket-wheel that is driven by a link belt 81 from a Wheel on the shaft 39. The wheel 79 has a radially notched hub 81 with a notch of which a dog pivoted to shaft 78, is engaged.

pinion to pass fromunrolled paper passes A horizontal arm 83, of the do acts in the dual capacity of a pointer and also as a stop, with a dial-ring 84 fixed concentrically of shaft 78. The upper face of the dial-ring issuitably graduated, as in feet, and an adjustable stop 85 is fixed to it with which the arm 93 contacts and locks the machine when the arm reaches the stop. The operator then cuts off the pasted and trimmed strip with his shears, raises the arm until it passes the stop in the further operation of the machine, and dropping the arm again to horizontal position, continues the pasting v and trimming of another strip.

lVhile I have illustrated and described my invention with. more or less minuteness, it is capable of many modifications without departing from the spirit of the invention, and I therefore do not desire to be held strictly to the construction shown and described nor any more than is required by the appended claims.
