To all whom it may concern."

Be it known that I, PAUL W. BIDWELL, a citizen of the United States of America, and resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Paper-Finishing Machines, of which the following is a full, clear, and exact description.

This invention relates to machines, for the surface finishing of paper, of a class comprising peripherally cooperative rotative cylinders maintained in pressure one sidewise against another-and having cloth or other appropriate material forming working coverings for the faces thereof which are in conjunction, and between which the paper, to partake of a surfacing or finish corresponding to such face coverings for the cylinders, is passed.

A principal object of this invention is to so construct and organize a machine of the general character indicated that the covering or coverings for the co-acting periph eral portions of one or more of the cylinders may be .practicably constituted by extremely long endless aprons, to produce cross seam marks in the paper at but infrequent intervals, which aprons, nevertheless, are so mechanically controlled that they acquire folded. dispositions at locations comparatively near the cylinders, and within a comparatively small space.

Other objects of the invention, as hereinafter rendered apparent, are attained in and by the constructions, and arrangement or combination, of parts embodied in the machine.

The invention is described in conjunction with the accompanying drawings and is defined in the claims.

In the drawings :Figure 1 is a side elevation of the improved machine, certain appurtenances thereof being shown in vertical section. Fig. 2 is' a front elevation of the machine. .Figs. 3 and at represent in elevations at right angles to each other, a provision for the displacement of the receptacles in which the long aprons may be disposed from working relation to the machine whereby receptacles for other aprons may be brought to place. Figs. 5 and 6 are diagrammatic "iews showing modifications or entensions of the idea of means comprised within the present invention and hereinafter described.

In the drawings, 1 and 2 represent cylinders of the general character of calender rolls mounted in suitable hearings in the machine frame A, the lower cylinder being represented as journaled in fixed bearings a, while the upper one is journaled in movable bearings a to which cylinders pressure may be applied by the screws [2 having the operating hand wheels 6 B represents the driving shaft of the machine having the clutch pulley C thereon and by the pinion d meshing with the gear wheel 6 on the extendedjournal of the lower to texture or surface character, are each in their running endless length of several hun-.

fired, or even fully or more than a-thousand,

eet.

For the imparting to the paper to be finlshed a cloth-like surface, the aprons are made of textile material, either comparatively fine or coarse as required for the nature of the work to be performed in the machine and by making theaprons extremely long, more or less nearly as above stated, the transverse seam mark in each of the aprons will be brought to its working relation between the peripheral cooperative cylinders of the machine.

Means comparatively close to the cylinders are provided for causing a disposition of the portions of the aprons which are away from the cylinders in reversed loops or folds and within small space for the occupancy thereof; and to this end I provide upwardly open receptacle F and F adjacent, and one above, and the other below, the cylinders. lhese upwardly open receptacles are rounded at the side and bottom thereof and are supported in stationary positions in any suitable manner, one, for instance, being by brackets h suspended from the ceiling, and the other by brackets hrsuspended below the floor, which latter is apertured for the free run of the lower apron by one course thereof to and into the receptacle and by the other course thereof out and away from the latter.

i, z' 'and 71? represent rods or high tension rolls for the course of the apron running from the upper receptacle to a half encircL ing engagement down and around the upper cylinder 1; and i and 2' represent a pair of positively driven feed rolls having their location near the open edge of the receptacle at the side thereof for the incoming of the tape. These feed rolls are geared together, and one thereof is driven in any suitable manner, as by a driving band 11 running around a pulley i thereon and driven by a pulley i on a line shafting. These as shown are supported on the receptacle F.

A roll or other guide for the course of the apron D which has its returning course to the receptacle F is represented at 11 Located in relation to the course of the apron D running from the receptacle F to the upper cylinder and adjacent the latter is a device for the lateral expansion of the apron whereby it will run, comparatively v taut and unwrinkled in its width, to the cyl:

inder. And this device which is represented by G in the stated situation is what may betermed as a curved surfaced herringbone plate, the ribs or serrations from the middle to one end thereof being inclined reversely to those comprised between the middle and the other end of the plate so that under the tendency exerted by the reversed ribs or serrations to outwardly spread the apron passing thereover the desired effect is accomplished.

The apron the receptacle F to and with a half encircling engagement around the lower cylinder 2 has provided therefor the tension rods or guide rolls adjacent the lower cylinder 2; and in position to be rounded by the course of the apron E running to such cylinder isa device Gr to have thesame operative or expanding effect on the apron as the a pulley above mentioned one G. This is represented as what is commercially known as a barrel expander, and in itself not my invention, it being mentioned as to its nature, however, that it comprises a rotative cylinder having blades or slates sinuously or 'helically arranged around the roll and internal means for distending such blades at the side in engagement with the apron or belt running thereover and retracting them at the opposite side. This barrel expander is shown as having on its shaft Gr a pulley is around which runs a driving band 10 driven from k fixed onthe driving shaft of the machine.

Adjacent the open-edge of the receptacle F at which the course of the apron E-enters on its return from the cylinder 2 are a pair of positively driven feed rolls 7'' and 9' the E for its course running fromthe shaft G of the rotative expander, and.

expanding devices G and G of different spe-' cific characters, but both having substantially the same operative effect, it is to be here stated that both expanders may be of herringbone-plate type, or both may be of the rotative blade and barrel type.

In Fig. 1, H represents a supply roll of paper to be surface finished, H representing supporting brackets therefor, and'J represents the take-up or winding roll of the paper; J? represents the supporting brack ets therefor, and 00 represents the course of the paper running from. the supply to the take-up roll between the cooperative cylinders and the aprons forming continuously running or working faces of such cylinders.

Each endless apron of the extreme length heretofore emphasized, upon being positively drawn at the receiving side of the' curve-bottomed receptacle and precipitated thereinto will automatically dispose itself .into reversed folds as measurably indicated lot of the paper, only one of the aprons is employed in conjunction with one of the cylinders.

The machine may be adapted or equipped for imparting repeated surface finishings'on one or both sides of the paper, and it may also be adapted or equipped for imparting a surface finishing action several times to one side of the paper and a lessened number of surface finishing actions to the other side;

and in this connectionreference is made tothe diagrammaticview, Fig. 5, wherein the

cylinders

1, 2, 3 and 4 are represented, aroundand between which run the aprons D and E, the paper guidance being such as to receive two surface finishings on both of'the sides thereof.

The paper being subjected to the action of but three cylinders will receive double surface finishings on both of its sides, while if the number of cylinders were increased, a corresponding increased number of finishings on both sides would be acquired.

around and between all of which one of the aprons has its running course, while the other apron E is by the guide rolls m n,

after partially encircling the cylinder 1 diverted from its course around and between the

cylinders

2, 3 and 4 and again carried only between the cylinders 4 and 5. Under this arrangement the paper r..ceives the four finishings on its top side and but two on its under side; and, of course, variations may be made inthe number of the cylinders and the running arrangements'of the aprons whereby other relatively excessive surface finishing to one side is acquired beyond that imparted to the other side of the paper. Such variations of finish are often very desirable especially of what is known as cover papers, blotting paper and some other grades.

The cylinders of the set, of whatever number, may be composed of steel, chilled iron. or other metal, cotton, paper, husk or other fibrous material or a mixture of materials whereby the cylinders are hard and unyieldin g, or possessed of more or less resiliency or elasticity.

Cylinders of one or more of the kinds as just referred to may be employed in the machine as found best adapted to meet the surface finishing requirements thereof.

Indication is made in Figs. 3 and 4 of the manner in which receptacles for the accommodation, compactly of the aprons are movably supported so that one may be displaced from its working relation to the machine I proper to permit another one of the receptacles to be brought to working position.

- L represents atrackway from which by the trolleys or wheels 0 carried by the brackets p secured on the opposite sides of the receptacle, the latter has a suspension and running support.

Assuming that it is desirable to substitute for use in the machine an apron carried in one of the receptacles by another carried in a similar receptacle therefor, the one apron is disconnected at its transverse seam and.

run into its receiverwhich is then moved along on the trackway (the driving band for the receptacle-carried feed rolls being, ofcourse, temporarily disconnected), and then the other apron and its carrying receptacle is brought to place, the ends thereof carried in relation to their guiding means and to the cylinders and joined or seamed.
