PAPER FOLDING AND PASTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 488,271, dated December 20, 1892.
Application filed June 25, 1892- Serial No. 437,979. (No model.)
To all whom it may concern.-
Be it known that I, TALBOT 0. DEXTER, of Fulton, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Paper Folding and Pasting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention consists in a novel organization of a machine designed for inserting and pasting a supplemental sheet into the fold of the main sheet of paper. Said supplemental sheet may form twoor four pages and thus, when connected to a main sheet forming eight pages, a ten or twelve page paper is produced. And the invention also consists in certain peculiarities of the details of the machine as hereinafter fully described and specifically set forth in the claims.
In the annexed drawings Figurel is a side elevation of a paper folding and pasting machine embodying my invention, Fig. 2 is a plan view of the same, Fig. 3 is a rear end view, Figs. 4 and 5 are enlarged detail views of the mechanism for lifting one of the pasters and the shaft of the feed rollers, Fig. 6 is an enlarged plan view of a section of the gagebar, Figs. 7 and 8 are transverse sections respectively on lines 00, cc, and y, y, in Fig. 6, Fig. 9 is a face view of a section of the folding blade, Fig. 10 is a plan view of the main sheet of paper showing by dotted lines the line of folding and by full lines the lines of pasting, and Fig. 11 illustrates the method of inserting the supplemental sheetinto the fold bar twhich I hinge to the front edges of of the pasted main sheet.
Similar letters of reference indicate corresponding parts.
Arepresents the main supporting frame of the machine across the center of which extend the two folding rollers RRwhich are disposed contiguously side by side and journaled in suitable bearings secured to the frame A. The main sheet of paper to be folded and pasted is carried over the folding rollers in a direction parallel with said rollers by means of the usual longitudinally traveling tapes e-. Said tapes are arrunning on rollers ee. ranged at opposite sides of the folding rollers to carry the said main sheet of paper so as to lie with the center of its width over the bite of said rollers.
To the rear end of the frame A are firmly secured the brackets B-Bon which is journaled the rock-shaft Oextending across the frame parallel with the folding rollers R-R. On this rock-shaft are rigidly mounted the brackets C'-G'which extend upward therefrom and have firmly secured to their tops the feed table D-which is thus supported above the passage of the main sheet and is inclined toward the folding rollers and has its delivery edge over the bit-e of said rollers. Thisrock-shaft receives its rolling or rocking motion by means of an arm Efixed thereto in a pendent position and having pivoted to its lower end a roller E -by which it bears on a cam F-fastened to a counter shaft f-wl1ich is parallel with the rock shaft and receives rotary motion from the shaft g-of the driving pulley g-by beveled gears fand f" as shownin Fig. 2 of thedrawings. Aspring rod upushes the table in opposition to the pressure of the cam. The rocking of the shaft Otilts the feed-table Dso as to carry the delivery edge thereof toward and from the bite of the rollers RR-and thereby facilitates the delivery of the paper toward the said rollers.
In front of the delivery edge of the tableD is a gage-bar a-secured at opposite ends to the frame A. From the rear bottom edge projects a cushion or yielding plate c-, the free edge of which is in the path of the edge of the folding-blade G. For said cushion I prefer to employ a stout rubber strip which ll connect to the bar a by means of a supplemental terposed between the heads of said bolts and III the vertical straps Cb -by which the supplemental bar is hinged to the plates ct", as shown in Fig. 7 of the drawings. The paper sliding from the feed-table D drops with its advanced edge onto the cushion c-, and, in order to prevent said edge of the paper from on the top of the cushion 0 when in its normal position. Said stops are adjustably secured to the gage-bar by means of stems b projecting horizontally from the stops and passing freely through perforations in the bar a, and set-screws b-inserted in screwthreaded sockets in the top of the bar a bear with their inner ends on the stems b', and thus confine the stops in their adjusted positions. The folding blade G is attached to and actuated by a vertically reciprocating pitman -which receives motion from a lever T- pivoted to the frame and connected at one end to said pitinan, and having pivoted to its opposite end a roller, by which it bears on a cam I-fastened to the countershaft, f. Said folding-blade is above and in line with the ciprocating movement of the pitman P causes the blade to intermittently descend and enter between the folding rollers immediately above the bite thereof.
The mechanism thus far described performs the function of foldingthe paper, which is effected in the following manner. The main sheet of paper is carried by the tapes e (2 over the top of the folding rollers and by means of suitable stops in the path of the paper it is arrested so as to hold it with the center of its width directly over the bite of the rollers R R. While the main sheet is in this position the attendant of the machine places the supplemental sheet upon the table D which is then automatically tilted by the mechanism hereinbefore described. The tilting of said table causes the supplemental sheet to slide down until said sheet is arrested by the contact of its advanced edge with the stops 5. Said edge then resting upon the cushion o. By the time this is effected the folding blade G descends and first comes with its bottom edge into contact with the top of the marginal portion of the supplemental sheet, and, in the farther descent of the blade, the marginal portion of the sheet which has rested on top of the cushion o, is bent up and pressed tightly against the side of the blade G by the free edge of the cushion c. Said blade thus receives a secure hold on the edge of the supplemental sheet and carries the same down onto the subjacent main sheet and forces the combined sheets into the bite of the folding -,rollers It which rotate and draw the said sheets with downward projecting pins (1 d which pierce the paper in the descent of the blade.
In order to allow the main sheet of paper to be readily introduced to the feeding devices I employ at the feeding side of the machine a shaft h disposed at right angles to the folding rollers R R andjournaled in suitable bearings. To this shaftI fasten arms h h in the free ends of which I journal the shaft 6" of the upper or biting tape-rollers e, and to readily introduced between top and bottom rollers e 6.
Automatically with the folding of the paper as before described I paste the supplemental bite of the folding rollers RRand the resheet to the main sheet by means of the following devices. To the underside of the tiltin g table D near the delivery edge thereof I attach a paste-trough j provided in its bottom with a slot through which protrudes thelower portion of the periphery of the pasting-roller j secured to the end of the shaft k which extends to one side of the frame A and is journaled in suitable bearings, and by means of a sprocket-wheel attached to said shaft and a sprocket-chain connecting said wheel with another similar wheel connected to a suitable rotary shaft, the aforesaid pasting roller receives rotary motion. The attachment of said pasting device is one of the salient features of my invention in that the table D, when in its normal position,supports the paster ataproper elevation above the main sheet to allow the latter to freely enter between the folding rollers, and in tilting the table the paster is carried nearer to the said rollers and brought in contact with the main sheet and thus pastes the sheets a greater distance across the same. On the opposite side of the folding rollers R R is another paster disposed in a line at right anges to the folding rollers and over the plane of the feed passage of the main sheet of paper. This paster is supported movable vertically and constructed asfollows: Along one side of the frame A and mounted thereon is a rock-shaft L to one end of which is fastened a horn l which extends across the top of a cam Z attached to the rock-shaft O on which the tilting table D is mounted. To the opposite end of the rock-shaft L is firmly secured an arm n which is thus oscillated in a vertical plane. To the free end of this arm is secured the paste-trough 0 which is provided with a slot in its bottom, and through which slot protrudes the bottom portion of the pasting roller 0 fastened to the end'of a shaft 19 which is parallel with the arm n and is journaled in the bracket 7' by which the arm n is attached to the rock-shaft L. A pinion t fixed to the shaftp and meshing with the pinion of the subjacent roller R imparts rotary motion to the shaft 19 and pasting roller attached thereto. By the arrangement of the two pasters at opposite sides of the folding rollers R R the in serted supplemental sheet becomes pasted to both sides of the folded main sheetin the passage of said sheets between the said rollers and thus said sheets are securely united.
