CORRUGATING-MACHINE.

Specification of Letters Pacent.

Patented Feb. 16, 1911a.

Application filed March 3, 1914. Serial No. 822,127.

In the preferred form of my invention, a I

heated revoluble roller provided with corrugations coacts with a second heated revoluble roller provided with corrugations which intermesh with and are movable longitudinally with reference to the corrugations of the f first roller, the latter being provided with a cam which operates an oscillatory lever mechanism whereby the second roller is movable longitudinally in contact with said first roller.

In the accompanying drawings, Figure 1 is a front elevation of a machine embodying my improvements; Fig. 2 is an elevation of the end thereof from which it is operated; Fig. 3 is an elevation of the opposite end of the machine; Fig. 4 is a perspective view of the detached lever mechanism; Fig. 5 is a broken perspective view .of the heating -mechanism; Fig. 6 is a sectional view'of an end of a corrugating roller and its journal; Fig. 7 is an enlarged plan view of a section of a corrugated roller; Fig. 8 is an enlarged sectional view of apart of a corrugated roller; and Fig. 9 is a broken sectional view of a modified roll construction.

The machine, as illustrated in the drawings, comprises the housings 1 provided with the blocks 2 in which are mounted the journals 3 and 4 of the corrugated roller 5, and the blocks 6 in-whioh aremounted the journals 7 and 8 of the corrugated roller 9.

The journal 3, which carries the fast and loose pulleys 10 and 11, has fixed thereon a cam12. A lever 13, fulerumed on the hearing 14 fixed to the housing 1, is provided with the bifurcations 13 forming a yoke within which revolves the cam 12, the yoke being provided with a roller 14' which engages the cam whereby the lever is oscillated when the roller 5 is revolved. A channel 7' in the journal 7 has a loose collar 15 engaged therein, the collarbeing provided with the laterally extending hubs 15, on which are engaged the links 17 connected with the,

bifurcations 13, whereby theosoillation of the lever 13 effects the reciprocation of the roller 9.

The rollers are made hollow for the purpose of facilitating the operation of heating them, and, as illustrated in Figs. 7 and 8, they contain the radial passages 18 for heated gases. The heating operation is suitably effected by the introduction, through the journals of the respective rollers or either of them, of an air pipe 19 having a perforated section 20 within the roller and a gas pipe 21 having a perforated section 22 within the roller, the jets delivered from the respective perforations intermingling to provide the desired combustible mixture' A blower 23 may be used to force'air through the pipe 19. It will be understood that instead of heating by gas, the operation may be effected by forcing steam through the pipe 19.

As shown in Fig. 9, the lower roller 5 may have its ribs 5 provided with notches 5 for holding the paper against lateral movement with the roller 9, the paper being engaged in the notches or by the irregularities of such ribs to provide the necessary frictional resistance against slipping.

In operation, the revolution of the corrugated roller 5 effects the simultaneous revolution of the corrugated roller 9 intermeshing therewith, while the revolution of the cam 12 with the roller 5 effects the oscillation of the lever 13, which acts through the links 17 and collar 15 to effect the reciprocation of the roller 9, whereby the paper board passing between the rollers 5 and 9 is corrugated by the revolution of the rollers and ironed by the longitudinal movement of the reciprocating roller. The effect of this operation is to give the desired set to the corrugated product by ironing it simultaneously with crimping it, with distinct improvements in the matters of economy of operation, smoothness of finish and perfecing the revolution of the other of said rollfl ers, and means whereby the revolution of one of said rollers effects the longitudinal movement of the other of said rollers.

4. The combination of housing mechanism, a corrugated roller journaled therein, a second corrugated roller journaled in said housing mechanism and movable longitudinally therein, means whereby said first roller reciprocates said second roller, one or more of 'said rollers being hollow and having passages for a heating medium, and means for heating one or more of said rollers.

5. The combination of a corrugating roller having means for obstructing the lateral movement of material pressed thereon with a corrugated roller coacting with said roller first named, and means for reciprocating said .second roller longitudinally.-

6.,The combination with a pair of intermeshing corrugated rollers, with mechanism whereby said rollers are revolved, and mech RALPH w. NAZEL.
