To aZZ whom it may concern.-

Be it known that 1, AUGUST 0. KRONQUEST, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Corrugating Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The main object of my invention is to corrugate sheet-metal vessels, and particularly cylindrical, conical, or frustum-shaped vessels.

It consists in certain novel features of construction and in the arrangement and combinations of parts, as hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a side elevation of a corrugating-machine embodying my invention. Fig. 2 is afront elevation of the same, parts of the machine being broken away and shown in section. Fig. 3 is a vertical section of the machine on the line 3 3, Fig. 2. Fig. 4: is a horizontal section on the line 4 4, Fig. 3, showing the stationary die and its support in plan View; and Fig. 5 is an enlarged vertical section of the dies on the line 5 5, Fig. 3, and a front elevation of the rotary face-plate or holder, a part of which is broken away and shown in section to show its actuating connections.

A designates a suitable column or frame upon which the parts of the mechanism hereinafter described are mounted. It may be conveniently cast, as shown, in the form of a hollow column or standard, with a suitable base to rest upon a floor or other foundation and support it firmly in an upright position.

B and C are corrugating-dies constructed and arranged to form one or more corrugations of the desired shape at a time. The

stationary die B is mounted upon the upper side of an arm or support D, formed at its rear end with a cylindrical shank d, by which it is adjustably secured in the column A. The movable die 0 is formed on the upper side with a cylindrical shank C, which is adjustably secured in a slide E by means of a clamping-block e, bolted to said slide. The slide E is movable vertically toward and from the stationary die B in ways ct a on the column or frame.

The shanks c and d are arranged at right angles or transversely to each other, so that the two dies may be adjusted by turning said shanks in their bearings to work properly together. Dies of dilferent forms and sizes maybe used to produce corrugations of vari ous shapes and to operate upon vessels of different sizes.

F is a driving-shaft supported horizontally in suitable bearings at the upper end of the frame or column, above the slide E. It is formed or provided with an eccentric or crank f, which is connected with said slide by an adjustable pitnoan G, comprising a box g, mounted upon said crank, and a rod g,thread ed at its upper end in a socket in said box and having a ball-and-socket connection at its lower end with said slide. I By turning the rod g the connection between the crank and slide is lengthened and shortened and the upper movable die is adjusted to work properly with the stationary die or to operate upon vessels of different sizes.

H is an annular rotary face-plate or holder which is adapted to turn upon the periphery of a stationary plate or ring I, mounted upon the support D between the column A and the stationary die 13. This ring I may be formed with the arm or support D and is arranged eccentrically thereto, so'that its periphery passes on the upper side below the working face of the stationary die B, as shown in Figs. 2 and 3. The face-plate or holderH is formed in its front side with one or more concentric annular grooves h, adapted to receive and hold the rims of the vessels to be corrugated. On the back side said holder is formed with an annular channel, in which a flanged ring J is fitted to turn. Between the rearwardly-projecting flange on the outer margin of the face-plate or holder and the forwardly-projecting flange on the inner edge of the ring J are interposed intermittent friction grips or dogs K. These grips are pivoted at their inner ends in the flange on ring J and are held in yielding engagement at their outer ends with the flange on the faceplate or holder H by springs 70. The ring J is held in place in the face-plate or holder H by a ring j, attached to said face-plate and overlapping said ring J. The face-plate or holder is held in place upon the bearing plate or ring I by keepers 'i, bolted to the sides of the die-support D and projecting outwardly therefrom over the inner edge of said faceplate, as shown in Figs. 2, 4., and 5.

L L are transversely-slotted segmental clamping-plates adjustably attached to the front side of the face-plate or holder H by bolts Z, passing through the slots in said clamps and threaded in said face-plate. They are adapted to be set up against the outside of the vessel, next to its rim, which is inserted in one of the grooves h in the face-plate, and to securely hold the rim of said vessel in said groove while the vessel is being corrugated, as hereinafter explained.

M is a crank wheel or disk mounted upon one end of the shaft F. It is formed in its outer facelwith an undercut groove m, extending diametrically across it, and in said groove is adjustably secured the shank of a crankpin m.

N is a horizontally-disposed lever fulcrumed at its rear end to a bracket on the frame or column A and formed at its front end with a longitudinal slot 02, which is engaged by said crank-pin. The lever N is connected by a rod 0 with an army", projecting radially from one side of the ring J.

The machine herein shown and described is designed, primarily, to corrugate the sides or body or complete the corrugation of sheetmetalvessels the bottoms of which are formed and corrugated separately and afterward attached to the body or sides. The machine so constructed for this class of work operates as follows:

Suitable dies for forming corrugations of the desired shape on a vessel of a given size having been inserted in the machine and adj usted to work properly together and the feeding mechanism having been properly set by the adjustment of the crank-pin m to turn the vessel by intervals exactly corresponding with the width of the corrugations produced by the dies, the vessel to be corrugatedis inserted between the dies, the upper die being raised, and its rim is secured by the clamps L in the proper groove h on the face-plate or holder H. When the vessel to be operated upon has a bottom which has been previcorrugations, according to the width and con struction of the dies, is formed, the face-plate and vessel attached thereto remaining quiescent during the operation. As the slide E ascends and the dies are separated the ring J is turned in the direction indicated by the arrow on Fig. 2 by means of its connections with the crank-wheel M. When said ring is turned in this direction, the grips or dogs K are forced outwardly into engagement with the flange on the face-plate or holder H, thereby causing said face-plate to turn with said ring an interval corresponding with the width of the corrugation or corrugations formed by the dies B and 0. Another section of the vessel is thus presented in proper position for the operation of the corrugating-dies. As the slide E, with the die 0, descends, the lever N also descends, turning the ringJ backward in a direction opposite that indicated by the arrow on Fig. 2. When turned in this direction, the grips or, dogs K yield at their outer ends against the tension of the spring away from the flange on the face-plate or holder H, which remains quiescent until it is again turned forward in the manner above explained.

The operations above mentioned being repeated in the manner described, the corrugations are progressively formed, one or more at a time, the vessel being intermittently turned forward when the dies are separated until a complete revolution is made, whereupon the machine is stopped either manually or automatically by means not shown. The corrugated vessel is detached and removed and replaced by another.

In corrugating the sides of vessels the bottoms of which have been previously corrugated the dies B and C are made to overlap the previously-formed corrugations, so as to produce'unbroken continuations thereof, the upper die being transversely recessed to receive the seam or joint between the bottom and body of the vessel, as shown in Fig. 3. The corrugations are thus made to pass through the joint between the parts of the vessel.

Various changes in minor details of construction and arrangement of parts may be made without affecting the principle or mode of operation of the machine and without departing from the spirit and intended scope of my invention.

I claim- 1. In a corrugating-machine the combination with dies and mechanism for opening and closing said dies, a rotary face-plate or holder provided with means for attaching a sheetmetal vessel thereto in position to pass on one side between said dies, and means for intermittently turning said face-plate or holder when the dies are separated, substantially as and for the purposes set forth.
