MACHINE FOR FOLDING CORSET PARTS.

SPECIFICATION forming part of Letters Patent No. 225,574, dated March 16, 1880.

Application filed November 20, 1879.

To all whom itmay concern:

Be it known that I, AUGUSTINE B. CURTIS, of Birmingham, New Haven county, Connecticut, have invented Improvements in Machines for Folding Fabrics, of which the following is a specification.

My invention relates to machines for folding the edges of corset-sections and other fabrics; and it consists in certain improvements whereby the folds may be regulated and the folded edges brought together.

In the drawings forming part of this specification, Figure 1 is a longitudinal section of a cor'set-section-foldin g machine, showing my improvements; Fig. 2, an end view, looking in the direction of the arrow, Fig. 1; Fig. 3, a cross-section on the line 1 2, Fig. 1; Fig. 4, a perspective view of one of the folders; Fig. 5, a plan view, and Figs. a b c d 6 dia grams showing the successive forms to which the edges of the fabric are folded.

In machines of this class heretofore made, an upper cylinder, A, and two lower disks or cylinders, B B, have been arranged as shown in Figs. 1 and 2, turning in bearings of a standard, C, and-a folder, D, consisting of a mandrel, g, with bent folding-plates, f f, has been arranged opposite the rollers and shaped to fold the edges of the sections or fabrics at :0, Diagram (1., successively to the positions shown in Diagrams b 0, when they are passed between the rolls and flattened, as

at d.

Toregulate the extent of either fold inde- 3 5 pendently of the other, I provide the mandrel g with a rib, 2', along its lower edge, which rib determines the position of the seam uniting the fabrics, the portion y of each fabric above said seam lying over the adjacent side of the no mandrel. If the rib is central, both portions 3 will be folded alike 5 but if the rib is to one side or the other one portion y will be carried with its edge nearer the web a, supporting the mandrel, so that this portion will be folded shorter than the other. Thus, if the rib is to the right, as shown, the right section will have a shorter fold than the left section, so

that when the two are brought together, as

in Diagram 6, the edge of the left section will extend beyond the other.

The contrary will be the result if the rib is at the left.

To permit the required effect without changing the mandrel, the rib z may form part of a piece adjustable to the right or left and capable of being secured after adjustment.

Heretofore the sections have left the machine in the form shown in Diagram (1. To fold them automatically together in the position shown in Diagram 0, I employ a second folder, E, constructed to receive the sections as they pass from the rolls and bend them together; and to accommodate the folder E to the irregular curved line in which the fabrics travel when the sections have curved edges, I pivot the folder E, or suspend it, so that it will assume the line in which the edgesv of the fabrics travel.

It will be apparent that the form of the rolls will depend upon the fold to be given, that the rolls may be geared and driven or be covered with adhesive material, and all moved by the friction of one driven roll.

To prevent the injury that results from folding fabrics having cross-seams I interpose strips of rubber s, or springs, between the journal-bearings and the tops of their boxes or guides, which will permit a slight yielding of the rolls when an extra thick piece passes between them.

Without confining myself to the construction shown, and without here claiming the combination of rollers A B B and folder D, which is the subject of a separate application for Letters Patent,

I claim- 1. The folder D, combined with pressure cylinders, and consisting of a mandrel, g, provided with a rib, t', and bent plates f f, substantially as set forth.

2. The combination, with the mandrel, of a rib, '13, substantially as and for the purpose set forth.

3. The combination, with the upper roller or cylinder and the lower parallel cylinders,
