MACHINE'FOR PASTlNG A' ND MOUNTING SHEETS.

SPECIFIGATION forming part of Letters Patent No. 546,506, dated September 17, 1895. Application filed July 1, 1895. Serial No. 554,563- (No-model.)

To (0Z6 whom it may concern.-

Be it known that I, HARRY CARLISLE, a subject of the Queen 0 Great Britain, residing at Shutesbury, in the county of Franklin and State of Massachusetts, have invented a new.

and useful Improvement in Machines for Pasting and Mounting Sheets, of which the following is a specification.

My invention relates to amachine forpasting printed, lithographic, or photographic sheets and mountin thesame upon a back ing-sheet of cardboard of any desired thickness suitable fort-he size and uses of the sheets, which are of pictoria'i or ornamental character for advertising and other uses. Heretofore these sheets have been pasted and mounted by hand, and the inoistening action of the paste and the action in various directions of the brush or other device in handmounting the pasted sheet upon the sheet of cardboard inevitably stretched the pasted sheet more or less unevenly, so as to change its proportions, with the result that it was difficult, if not quite impossible, to die out ornamental forms or to cut up with-true margins sheets on which a number of pictures were printed; and the object ofmy invention is to overcome these difliculties.

In carrying out my invention I employ a receptacle for a pile of printed sheets, a table adjustable for the size of the sheets being pasted and mounted, and upon which table one sheet at a time is deposited anddelivered to the gripper upon a revolving cylinder, a brush-for pressing the sheet against the cylinder and for slightly moistening the same, a trough for paste anda pasting-roller running thereinjand in contact with the cylinder for transferring paste to the sheet, a stand for holding the pile of superposed sheets ofcardboard, a table on which one sheet at a time as the same is united to the sheet of cardboard. The sheet of cardboard with a printed sheet attached passes along onto an endless belt or apron and is conveyed away and re ceived upon a table or other receptacle. 3e-

fore the sheet of cardboard and attached is a partial elevation and section of the cylinder and pressure-roll and gears transversely of the machine.

The main side frames are shown at A, and the upper frames at A, and B are brackets extending 'out from one side of the machine and carrying the table 0, and C is a recep tacle for superposed printed sheets placed face up. l

D represents brackets extending out from the other side of the machine and carrying a table E, and E is a receptacle for superposed sheets of cardboard. v

F is the power-shaft in suitable bearings upon the frame A, and F is the driving-pulley. The cylinder a is provided with a shaft mounted in suitable bearings upon the main frame of the machine, and part of the cylinder is of reduced diameter. Upon one end of the cylinder-shaft is agear a, meshing with a small gear upon the end of the power-shaft F, the same being driven byv the pulley F in the direction of the arrows, and upon said cylinder a, is a gripper-blade a running lengthwise of the cylinder at one'edge of the part that. isof reduced diameter. A brush 1) extends across the machine between the main side frames and is mounted at its ends in suitable frames b, resting on the side frames, and the forward and backward adjustm nt of this brush is efitected by screws bi. A aste- Fig. 4 is a side elevation of the main frame, cylinder, and adjacent parts in larger size; and Fig. 5'

g erases roller 0 is provided with a shaft and :at one end with a gear 0', which meshes with the gear a on the cylinder-shaft. This paste-wheel is supported by" frames at the ends of its 5 shaft, which frames rest upon the main side of the machine, and d is a trough extending across between the main side frames andat an inclination, serving as-a catcher for the waste paste that may fall from different parts of the machine in its operation. .Apressureroller 8 is provided with a shaft 0, that is inv suitable bearings 6 upon the upper side frames A of the machine, and upon the shaft 0 is a loosegear e meshing with the gear a, of tho'cylinder a, so that the power-shaft F, through the gears, operates the cylinder and paste-wheel and the pressure-roller. The hand adjusting wheels. and screws 3 s for the boxpr bearing of the pressure-roller are to be operated to bring said pressure-roller nearer to or farther from the cylinder a, and the up-. per wheel and screw 8 are to be elevated slightly abovethe box of the shaft, so as to permit the pressu re-roller to rise for'inequalities in the thickness of the cardboard sheets.

The table 0 is slottediat opposite sides len- 'gitudinally of the machine Fti'lfi-iSmpQ-Oildld with a cross-bar f and standards f, that pass through said slots and through the ends of the cross-bar", and there are guide-rods f 2 passing through the standards ffi'the object of the cross-bar, standards, and guide-rods being to provide for different sizes of printed-sheets, said parts being capable cit-adjustment and asliding' motion, so that whatever size the. printed sheet may be its forward edge can be brought into the right position for engagement by the gripper-blade. A guidearod g is secured along one edge of the table E, and a sliding standard g surrounds this guide-rod and-rises therefrom, and to this standard 9 is, connected a rod 9 the opposite end of the rod being connected to the gear a by a crank- 5o pin, so that with the rotation of the gear a longitudinal sliding motion will be imparted to'the standard 9. Upon the surface of the table E areslideways h h, and straddling these slidewaysis a; cross-head h, to which Qcross-head is connected a slotted bar k and a cross-head 1 extending laterally of the table E, isprovided and connected to thestandard g, at one end, and upon its opposite end is a roller 1''. vThe slotted bar h and cross-head it are ad'justablyconnected to the cross-head 2' by'a. bolt7, This adjustment between the cross-head iand the bar k is necessary to provide for the rarious sizes of the sheets of cardboard.

Adjacent to he pressurerollereand about on line with i aft o'is a trough 7c,supported I at the sides .7 to machine and'provided with upon the sli a scraping'b ade'k, and extending trough it is at 76. The surp removed from e surface of the roller e by the scraper into the trough is, and as said trough 7c is inclined toward the end where the spout k is 1ocat'ed the accurnniated paste runs by gravity down said trough and is discharged through the spent 7: into the paste holder or box 61 beneath. I provide an endless belt or apron Z, running upon a series of rollers Z and e'xtendin from near the c lindot a longitudinally over ti table (I and beyond, and I provide an adjn virapplying a tension by an ad u-sting d to this endless belt Z, which belt or a ron is preferablyniade of rubber fabric, and 1 prorolier Z for vide a scraper m and adjusting tbevicewm therefor by which pressure is appiiedio the scraper m, so as to thoroughly cleanse the surfaceof the endless belt from paste or water. A roller 12 is provided, and around the .same this endless belt 6 passes, and on the end of its shaft is a sprocket Beneath the roller n is a cleansing-brush n 'in'- a tank of waterin and on theshaft of said brush is a sprocket 4, and a chain 5 passes around the sprocket 6 on the power-shaft Rand in turn around the sprockets 3 and at, so as to rotate the roller n and drive the endless beitand rotate the cleansing-brush n to cleanse the surface of the endiess belt and wash thesaine with the water taken up from the tank 22?, and the surplhs water in turn is removed by the scraper m, so as to leave the advancing portion of the endless belt or apron clean.

The operation of the machine is as foilou's: The cylinders, and adjacent rrts being tated by power, as hereinbetore descrii'r an attendant takes from the pile of printed sheets on the sheet-receptacle '6 one sheet t at atime and lays the same face up on timetable O, passing the forward edge of he printed sheet through an opening made betweenthe surface of the table and a shield 2, whose otfice is to actas a guide to locate the forward end ofthe sheet and to receive any paste thrown elf from the cylinder and prevent falling on the printed surface of the sheets,

and the back edge of the sheet is piecedagainst the crossbar j", which cross-bar has been previously set, hereinbefora de scribed, for the size of the printed sheet. in thisposition ot' the printed sheet its forward edge is lll'POSiilOll to be'engaged by the gripper bar a as the cylinder comes around. The rotation of the cylinder pulls the sheet with the printed face next/the cylinderoif the table :and draws the same downward past the brush .b, .the action of whichis to even thefsheet on the cylinder and to moisten the same slightly. lhe further rotation of the cylinder carries the sheet between the same and the paste roller 0,-so that the surface is thoroughly and evenly pasted. In the meantime another at tendant-tahes e c oard sheet from the receptacle an said cardboard sheet 2; j, on the table it is IZO- low the center of the pressure-roller e and the I union of these two commences. As the cylin- "der a revolves further the arm of the gripperblade strikes a cam-plate 10 upon the side of the mainframe, and the gripper-blade is thereby opened and kept open to receive the for- L ward edge of the next printed sheet, which has already been placed in position by the attendant upon the table 0 to be engaged as the gripper-blade closes by the action of a spring a as its arm a runs off the cam-plate 10. As the cylinder at advances from the point where the gripper-bladeis opened the printed sheet by the pressure exerted by the roller 2 is united to the under face of the cardboard sheet and the surplus paste is pressed out sidewise, and as the""cardboard sheet passes'o'ut from between the cylinder and pressure-roller a row of surplus paste is left upon the pressure-roller to be removed by the scraper 70 into the trough k and to gradually, as it accumu-v lates, find its way by the spent it into the paste-holder d. The'cardhoard sheet with the printed sheet attached passes'out onto the endless belt or apron Z, is conveyed along upon.

such belt, and at the distant end is removed by another attendant and the successive sheets placed in a pile'or set aside for drying. The

second printed sheet, as received by the cyliuder (1, occupies exactly the same position upon the cylinder as did-the previous'sheet, so that while the surface of the cylinder not occupied by the sheet receives paste from the pastingroller the same does not get upon the printed face of the sheet, and as the cylinder revolves this paste with each rotation is largely or wholly removed by the action of the brush 1) and is to a greater or less extent delivered upon the surface of the sheet as the same passes the brush. These operations are continuously repeated for each sheet. Should there be any paste upon the edges of the cardboard as the same is delivered upon the end less belt, this paste will probably be left upon the belt, and as the belt passes its lowest point it is wetted and washed by the action of the cleansing-brush or brush-wheel n, and the scraper m, which extends laterally across the endless belt and presses thereon, removes all of the surplus water and paste, so that as the belt. returns to the point for receiving each cardboard sheet it is cleansed, so that no pastev remains to touch the printed faces of thesheets.

The cardboard sheets employed not only vary in area but in thickness, and provision cardboard.

must be made for the varying thicknesaand it frequently happens that a number of sheets supposed to be of the same thickness will vary slightly, so that a yielding action must be provided for in connection with the pressureroller e, and, while said pressure-roller with thin sheets of cardboard should revolveat apmoximately the same surface speed as the cylinder (1, when the thickness of the cardboard sheets is materially increased there would arise a binding action because of the looseness between the gears ofand e that might have a tendency to tear the moist printed sheet as the same is being pasted upon the surface of the cardboard. To provide for these contingencies and to insure the pasting of the sheet and overcome the liability of tearing the same, I place the gear-wheel e loosely upon the shaft 0 of the pressure-roller, and I provide a hand-wheel 'r' upon a threaded end of the shaft 0, as will'be seen in Fig. 5,

and-between the hand-wheel'r and the loose gear-wheel e I provide a rubber washer r and a clamping-nut r on the outer end of the threaded shaft, outside the hand-wheel, and the object of these parts is to clamp and frictionally hold the loose gear-wheel e against a'collar 8 upon said shaft 0 with just suliicieut power to cause the pressure-roller to rotate with the cylinder at, and should there be any strain on the parts because of difference in speed the shaft will slip in the hub of the gear 2 so that no harm will come to theprinted sheet as the same is being pasted upon the Any desired pressure can be brought to bear by the operation of the handwheel 4' upon the loose gear e? to produce friction between the parts.

In my improvement there is little or no stretch of the printed sheet as the same is moistened by the paste and the sheet secured to the sheet of cardboard, as the action is so quick that there is no time for the paste to strike through the paper, so that with printed sheets containing a large number of small pictures there is no distortion of the parallel lines between the pictures,.such as is the case where the sheets are mounted by hand, and no difficulty arises in sheets mounted by this machine in cutting up or dieing out the sheets after they are pasted to the cardboard.

I am aware that machines have heretofore been made and used wherein a continuous web of paper or of fabric has been employed and has been pasted and passed through a machine, and upon the surface of the same too sheets of cardboards have been secured by to be taken by the gripper, n pnsterollcr for pasting the backs of the printed sheets, adjusteble means for locating one sheet of card board at n time and for moving the same to meet the pasted printed sheet, and a roller above the cylinder for pressing the printed. sheet and card-board together, snbstnnii-tilly as set forth.
