To all whom it may concern.-

Be it known that I, ELIJAH G. RINNER, a citizen of the United States, residingat Coshocton, in the county of Coshocton and State of Ohio, have invented a new and useful Machine for Facing Corrugated Paper, of which the following is a specification.

This invention relates to machines for facing corrugated paper; and its primary object is to provide means of novel construction whereby a facing-sheet may be held in contact with a corrugated sheet subsequent to the application of paste and said paste dried by the direct contact of products of combustion and heated 'air with the paper-holding means.

A still further object is to provide a holder of novel form to which flames may be directly applied without injury thereto or to the paper sheets carried by the holders.

With the above and other objects in view the invention consists of a frame in which are mounted endless belts adapted to be operated in unison by mechanism provided for that purpose, "each belt being formed of a multiplicity of metallic slats which are so proportioned and arranged as to form a flat unbroken surface wherever the belt is straight.

The adjoining straight portions of the two belts are parallel and are adapted to receive between them the pasted corrugated and facing sheets and to carry them longitudinally through the machine. During this movement heat is applied directly to the belts, so that the paste is quickly and thoroughly dried.

The invention also consists of certain other novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a side elevation of the machine, a portion thereof being broken away to show certain parts in section. Fig. 2 is a section-on line a: as, Fig. 1. Fig. 3 is a section on line 1 y, Fig. 1. Fig. 4 is a perspective view showing two of the slats connected. Fig. 5 is a transverse section through the intermediate portion of one of the slats. Fig. 6 is a transverse section through the end portion of one of the slats. Fig. 7 is a perspective view of a heater for use in connection with a belt, and Fig. 8 is a detail view of a portion of a modified form of chain.

Referring to the figures by characters of reference, 1 is a frame of any suitable construction and preferably formed of channeled metal, and journaled upon the lower portion of this frame adjacent one end is a driveshaft 2, having a pulley 3 thereon for receiving motion through a belt 4 from any suitable source of power. A small gear 5 rotates with shaft 2 and meshes with a large gear 6, mounted on a shaft 7, which is rotatably supported in suitable bearings 8 and has a small gear 9 suitably fastened to it and meshing with an intermediate gear 10, the shaft 11 of which is supported, preferably, by brackets 12, arranged at one end of the machine. Shaft 11 carries sprockets 13, arranged between but close to the sides of the frame. Gear 10 meshes with another similar gear 14, secured to a shaft 15, which is journaled on brackets 16, disposed above brackets 12, and sprockets 17 rotate with the shaft 15 and are similar to and disposed directly above the sprockets 13.

Extending from the other end of the frame are brackets 18 and 19, the lower brackets 18 constituting supports for a rotatable shaft 20, having sprockets 21 thereon, while the upper brackets 19 support a shaft 22, carrying sprockets 23. Longitudinallyslotted supporting-plates 24 are secured to the sides of the frame at points between s

rockets

13 and 21, preferably by means of c amping-bolts 25, extending through the slots in said plates, andeach of these plates has an inwardly-extending arm 26. These arms support bed-strips 27, which extend longitudinally of the machine between the

sprockets

13 and 21.

Sprockets

13 and 21 carry an endless belt A of novel construction, and another similar belt B is carried by the sprockets 17 and 23. Each of these belts is made up of a plurality of similar slats, each consisting of iron or other heat-retaining material which will not be affected by the application of flames thereto. These slats have been indicated at 28, and each has a broad flat face extending throughout the greater part of the width of the machine, and the longitudinal edges of the slat are beveled and provided at their points of conjunction with the flat working face 29 with ribs 30, which extend throughout the length of the slat. Two sets of parallel ears 31 extend from one of the beveled faces of the slat adjacent its ends and overhang the rib 30, and projecting from the other beveled slat in alinement with the spaces between the ears 31 are ears 32. All of these ears have openings 33 therein to receive pivot-pins, whereby the ears of the slats maybe connected, as shown in detail in Fig. 4. Openings 34 extend through the end portions of the slats, and between these openin s each slat is channeled longitudinally, as shown at 35. The openings 34 are adapted to receive the teeth of the sprocket, so that when motion is transmitted to sprockets 13 and 17 through the mechanism described the two endless belts will be operated in unison.

That portion of the lower belt A which is located between the upper portions of sprockets i3 and 21 is held straight by the bedstrips 27, which, as shown in Fig. 3, constitute bearings for the ends of the slats 28. The hanging portion of the belt A can be supported in any preferred manner, as by means of strips 36, carried by angular arms 37, which are slotted longitudinally, as shown at 38, and are held in place by clamping bolts 39.

The upper belt B has its lower portion res't-.

ing close to a corresponding part of belt A, while its upper portion is supported by strips 40, mounted on longitudinallyadjustable arms 41, which are preferably secured to the frame 1 by means of bolts 42, extending through slots 43 in said arms. A roller 44 extends under the upper portion of belt B and between the strips 40, and this roller is journaled in boxes 45, slidably mounted in guides 46 and resting on a cam 47. This cam is mounted to swing on a bolt 48 and has a lever 49 extending from it, the weight of which serves to hold the box 45 normally pressed upward, so that the roller 44 will bear upward against the belt B and cause the same to be tensioned or taut under all conditions.

Any desired means, such as burners 50, extend under the upper and lower portions of belt A at desired points, and these burners may be supplied with fuel through inletpipes 51. If preferred, guards 52 can be extended over the burners to prevent flames from coming into direct contact with the belts. While ordinary gasburners have been shown inconn'ection with the machine,

also fed thereinto at the same time. The sheets will therefore be pressed tightly to gether by the belts and at the same time will be conveyed through the machine and over the heaters which are disposed under the upper portion of belt A. The paste will thus be quickly dried, and. when the sheets are discl'iarged from between the belts they will be permanently secured together.

Considerable importance is attached to the particular construction of each belt, because said belt presents a perfectly flat surface to the sheets, and. there is therefore no danger of the sheets becoming torn or otherwise disfigured, as would be the case where shoulders were formed in any way upon the belt. The machine can operate at a high speed, and the belt will retain the heat to such an extent that after it has been once thoroughly heated there is no danger of the same cooling to any appreciable extent between the heaters. The cams 47 serve to automatically hold the upper belt taut and to prevent it from crushing the corrugated sheet.

Instead of forming integral ears on opposite portions of the slats said slats can be connected, as shown at Fig. 8, by means of plates 53, which are secured upon the end portions of the slat and have their ends pivotally connected, said plates forming chains each link of which is fastened to a slat. This construction is much more simple than that in which the integral ears are employed, and should one of the links become broken it would only be necessary to remove it from the slat and the slat itself would not be injured.

The preferred form of the invention has been set forth in the foregoing description; but I do not limit'myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of the claims.

What is claimed is- 1. In a machine of the character described the combination with a frame; of an upper and a lower belt carried by the frame and each belt consisting of fire-resisting and heatretaining material, the adjoining portions of the belts being parallel, means for moving the parallel portions of the belts in the same direction in unison, adjustably-mounted bed strips for supporting the upper and lower portions of the lower belt, adjustable bedstrips for supporting the upper portion of the upper belt, and a gravity-operated tensioning device bearing upon said upper portion of the up er belt to hold the lower portion of said be t parallel with the corresponding portion of the lower belt.
