IMPROVEMENT IN MACHINES FOR TURNING THE EDGES 0F COLLAR-BANDS. 85c.

Specification forming part of Letters Patent No. 184,891, dated November 28, 1876 application filed March 6, 1876.

To all whom it may concern Be it known that I, ROWLAND S. NORTON, of Chicago, county of Cook and State of Illinois, have invented a new and useful Improvement in Machines for Turning the Edges of Collar-Bands and other articles of varying width, which is fully described in the following specification, reference being had to the accompanying drawings, in Which- Figure 1 represents a side elevation of my machine; Fig. 2, a sectional view, taken on the line w m, Fig. 1; Fig. 3, a sectional view of one of the tubular arms which carry the folding-guides; Figs. 4, 5, and 6, detail views of the standard and adjustable plates, upon which the pattern-wheel is mounted; Figs. 7 and 8, plan and edge views of one disk of the pattern-wheel Fig. 9, a plan view of the inner face of the adjusting-disk of said wheel;

' Fig. 10, a sectional view of the wheel, taken on the line y 3 Fig. 7. Fig. 11 represents a device to be attached to the wheel, to adapt it to large patterns; Figs. 12, 13, and 14, views of the adjustable devices upon which the folding-guides are mounted; and Fig. 15 represents a strip of collar-bands as prepared for the machine.

The object of my invention is to provide a machine upon which the edges of collars, collar-bands, cuifs, and other like articles may be turned and folded, ready for stitching upon a sewing-machine.

The invention consists in a circular pattern plate or cam, corresponding in size to the article before turning, and mounted upon an adjustable wheel, with which it turns, around which a prepared strip of articles passes to turning-guides which are mounted upon sliding arms controlled in their position by the pattern-cam, against the edges of which they press. It also consists in various subordinate devices and attachments, all of which will be hereinafter more fully described.

In the drawings, A represents a standard, upon which is mounted a pattern-wheel, B. The journal-shaft of the wheel is attached to a plate, a, which is adjustable vertically in dovetailed grooves upon a second plate, a, which, in turn, is adjustable horizontally upupon the standard A by means of horizontal slots a in the latter, and set-screws passing through the slots into the plate a. The wheel B is constructed with two disks, B and B, the former being provided with a hub and a flanged rim, within which the latterisrec'eimd, being also fitted about the hub. A series of sliding arms, b, are fitted in radial grooves in the disk B which are provided with a series of teeth or projections, 12, upon their inner sides, and with wedge-shaped flanges on their edges, which fit in corresponding guideways in the sides of the slots. They also carry points upon their upper ends, which project through the rim of the wheel, and upon the same ends screw-threads are cut. This inner face of the disk 13 has a spiral groove cut upon it, as shown in Fig. 9 of the drawings, into which the teeth on the slides b are fitted when the two disks are brought together. The disk B is movable independently about the hub of the disk B and by its rotation the slides are adjusted back and forth in the radial grooves of the disk B The disk B is provided with one or more pins, W, to assist in turning it around, and it is fastened to the disk B by a circular plate, D which is screwed to the hub of the other disk.

"A metallic circular pattern-plate, O,ismounted upon the wheel B by means of a series of holes, 0, in it,into which the points on the ends of the slides 11 are caused to enter, and through which they project. This pattern is made of the exact size and shape of the collarband or other articles before the edges are turned, and by means of the sliding arms b patterns of different sizes may be fitted to the wheel. For the purpose of accommodating very large sizes a short supplementary arm, 1), (shown in Fig. 11,) with a point at one end, may be screwed to the upper ends of the slides b, so as to extend their range of adjustment. Two standards, D, are placed upon opposite sides, and just in front of the wheel B, and upon them are mounted tubular arms D which inclose sliding rods d, which are forced inward toward the wheel by means of a coiled spring, (1 and are provided with small rollers d at their inner ends. The standards D are at tached to plates D whichslide in dovetailed grooves in other plates to adjust the distance between the standards. A short standard, E, is also mounted upon the inner end of each of these sliding rods, to each; of" which is atare placed in an inclined position, so that the ends farthest from the pattern will be nearer each otherthan their opposites. These guides are fixed to independent plates or wires, which are adjustably attached to other plates e which are also adjustably attached to the standards E. By these devices the guides may be adjusted both vertically and horizontally, so as to be brought into any desired position but the adjustment may be efi'ected by any other devices suitablefor this purpose. By adjusting the journal-shaft on which the wheel and patterirplate are mounted the latter is arranged so thatits edges will pass between the rollers on the ends of the sliding rods cl, andas the pattern is rotated with the wheel G the rollers follow the contour of its two edges, and thus the opening between the turning-guides always corresponds to the width of the pattern-plate immediately below them,

but at the point of egress must be the same as r the width of the turned article. A forked guide, F, is attached to the inner end of each of the sliding rods d by means of slots in the guides and setscrews f, so that they may be adjusted. A strip of articles cut to the pattern desired is fed through each of the guides F to the pattern-plate G, passing around underneath the latter. These strips are arranged to conform exactly to the pattern-plate at one or both edges, and are held in place thereon by means of wires f one end of which is attached to the upperend of a circular frame, Gr, within which the pattern wheel and plate, are located. The wire passes around underneath thepattern-plate, and is attached to a tension device, g, on the other end of the frame G, by means of which it is tightened about the pattern-plate sufficiently-to keep the stuff in place thereon. Two standards, H, are placed just in front of the tubular arms D in which are mounted two pairs of round bars, h, which are adjustable in slots in standards, so as to accommodate different thicknesses of the stuff 7 to be folded. Still another set of standards,

' such as collar-bands, collar-tops, cufl's, 850.,

ioined together, as shown in Fig. 15 of the drawings, which represents a strip of collarbands, L, prepared in this way for folding.

Wherever "there are re-entering angles in such strips, as at L, Fig. 15, it is necessary to slit the strip, as shown in the drawing, to insure the satisfactory folding of the cloth at these points by the turning-guides.

The operation of the machine is as follows The strips, prepared as described, are placed in the guides F, and carried underneath and around thepattern-plate, being arranged thereon, so as to exactly fit it, and held in place by thesurrounding wire and points on the endsof arms I). When the strips are brought round to the front again, upon the upper side of the pattern-plate, they are separated, the upper one being carried through the upper pair of turnin g-gnides, and the other one through the lower pair. Thence the two strips. are passed respectively through the upper and lower sets of round bars h, and are'conducted to the rollers I, the upper strip passing over the upper bar z, and over the upper roller, while the lower strip is carried underneath the lower bar 11 and under the lower roller. After passing around the rollers, as described, the two strips are brought together in front of the rollers and passed between them, the rollers being adjusted so that, when rotated by meansof the crank attached to the lower one in the direction indicated by the arrows in Fig. 1 of the drawings,the two strips will be drawn through them together. This action of the rollers causes the proper feeding of the strips to the turning guides, and the rotation of the wheel and pattern-plate, by means of which the position of the turning-guides is regulated. As

the strips pass through the turning-guides the edges are turned over, and as they pass immediately between the round bars h the folds are pressed down, which operation is continued as the strips are drawn tightly over the straight edges of the bars z, and completed by passing around and through the pressure-rollers. The folded strips are brought to one side and held in the guide K, sees not to interfere with the passage of the strips from the bars h to the rollers. The course of the strips in the operation described above is indicated by the dotted lines in Fig. 1 of the drawings.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, isj 1. In a machine for turning collar-bands and other like articles, a pattern'cam, O, of the size and form of the article to be turned, substantially as and for the purpose set forth.
