SPECIFICATION forming part of Letters Patent N 0. 374,498, dated December 6, 1887'.

Application filed April 27, 1887. Serial No. 286,312. (No model.)

To all whom it may concern:

Be it known that I, ADOLPH SEGAL, a subject of the Emperor of Aust1'ia-Hungary,and a resident of Camden, Camden county, New Jersey, have invented certain Improvements in Paper-Lining Machines, ofwhich the following is a specification.

The object of my invention is to construct a paper-lining machine which will be less expensive and otherwise more acceptable than the cylinder machines now used for the purpose, and this object I attain in the manner which I will now proceed to describe, reference being had to theaccompanying drawings, in which- Figure 1 is a side view, partly in section, of a paper-lining machine constructed in accordance with myinvention; Fig. 2, a plan view of the same with the conveying-belts and their carriers omitted, and Fig. 3 a transverse section of part of the machine.

A, B, and D are three frames,having guides for the bearings of pairs of rolls (6, b, and drespeotively, the upper roll of each set being adjustable and controlled by pressure-screws, so that the pressure exerted upon the paper passing between the two rolls may be regulated as desired.

Fis an end frame, having guides for the bearings of a pair of rolls, ff. The shaft of the lower roll a has three pulleys, 9,71 and t, the pulley 9 being intended to receive a drivingbelt,the pulley h to receive a belt which drives a pulley, h, on the shaft of the lower roll f, and the 'pulleyt' to receive a belt which drives a pulley, t", on the shaft of the lower roll I), the latter shaft having asecond pulley, j, which is intended to receive a belt for driving a pulley, j, on the shaft of the lower roll d, so that all the rolls are driven at the same surface speed. The lower roll f rotates in a pastetrough, f, and serves to distribute the paste upon the surface of the upper roll f, by which it is applied to the under side of a sheet of paper drawn from a roll, 0, suitably mounted adjacent to said roll f, the contact of the paper with the surface of the roll 7 being insured by means of an upper press-roll, 0. An endless belt or apron, G, of felt or other suitable material, passes around the upper roll a, thence between the rolls bb, thence around the upper roll (1, thence under a roll, m, over a roll, m, and under a second roll m, and thence to the roll a, and a similar endless belt or apron, H,

passes around a fixed roll, a, mounted in bearings in a bracket on the frame F, thence be tween the rolls a a and b b, thence around the lower roll d, thencearound a roll, p, and back around a roll, p, thence under a carrier-roll a, and back to the roll n. Between the rolls" a and d, therefore, these two belts are in contact with each other and travel at the'same surface speed, and these contact portions of the belts aresubjected to the heat of upper and lower steam-coils, I and J, carried by suitable bars, 8, at the opposite sides of the machine, shields t, of sheet metal,being preferably interposed between the belts and steam-coils, as shown in Fig. 1. Steam enters oneend of each of the coils I and J through suitable branches from the steam-supply main K, and the water of condensation is discharged from the opposite end of each coil through suitable branches into the discharge-main M. The rolls a,b,and d are hollow, and are also heated, the shafts of these rolls being tubular, and steam entering through the shaft at one end of the roll, while thewater of condensation is discharged through the shaft at the opposite end of the roll in a manner usual in calendering-machines. The sheets of pasteboard which are to be lined are deposited upon the projecting portion of the lower belt, H, between the roller 12 and the rolls a, and as each sheet passes between the rolls a the pasted sheet of lining-paper w is pressed upon the upper surface of said paste- 85 board sheet and caused to adhere thereto. The sheet of papery-with its lining pasted thereupon, is then carried forward by the belts G and H between the steanrcoilsl and J, so that the sheet is partially dried before passing be- 0 tween the heated rolls lib, from whichitis carried by the belt between the second set of steam-coils I and J, and thence between the heated rolls d d, so that when it issues from between the latter rolls it is perfectly dry and the paste is firmlyset.

Although I prefer to use three sets of heated rolls and two sets of steam-coils, as shown, I may in some cases dispense with the rolls d and the second set of steam-coils, the first set of steam-coils being in this case madelong enough to insure the proper drying of the paper in its passage from the rolls ato the rolls b.

It will be observed that the rolls m and p" are adjustable by means of screw-shafts w, so that the belts G and H may always be under proper tension.

The central frame, B, carrying the rollsb b, is higher than the end frames, A D, the object of this construction being to cause a slight bending of the sheet of pasteboard asit passes between the rolls b 72, whereby the upper surface of the sheet is stretched, and any wrinkles that may have formed in the lining-paper are removed therefrom. By this means, moreover, the steam-coils I and J are caused to occupy an inclined position,so as to facilitate the rapid dralinage of the water of condensation from said CO1 s.

The heating of the rolls a, b, and d may be dispensed with without departing from the main feature of my invention; but such heating is always preferred.

I claim as my invention- 1. The combination, in a paper-lining machine, of pasting devices, upper and lower carrierbelts, successive pairs of presser-rolls supporting and driving the belts,said pairs of rolls being located at a considerable distance apart, and means for heating the carrier-beltsin their passage from one pair of rolls to the next pair, all substantially as specified.

2. The combination, in a paper-lining machine, of upper and lower carrier-belts, three sets of rolls acting on thesame, the second set being in a different plane from the first and third sets, pasting devices, and means for heating the conyeyer belts, all substantially as specified.

3. 'The combination, in a paper-lining machine, of the pasting devices, upper and lower carrier-belts, successive pairs of presser-rolls supporting and driving said belts, said pairs of rolls being located at a considerable distance apart, and means for heating the rolls and for applying heat to the belts as the latter pass from one pair of rolls to the next pair, all substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ADOLPH SEGAL.
