EDWARD K. WARREN, OF THREEOAKS, MICHIGAN.

SPECIFICATION forming part of Letters Patent No. 739,461, dated September 22, 1903.

Application filed February 20,1901. Serial No. 43,044. (No modeL) T0 on whom it may concern:

Be it known that I, EDWARD K. WARREN, a citizen of the United States, residing at the village of Threeoaks, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Machines for Manufacturing Stiffening Material, of which the following is a specification.

This invention relates to an improved machine for the manufacture of corset-stiifeners from fibrous material.

The objects of the invention are, first, to provide a machine which shall properly manipulate and hold fibers, so that they can be wound into a flat bundle, wind them there, and then secure the same in such flat blade or bundle by suitable stitching. o

The machine is particularly adapted for the manufacture of the stiffening material called featherbone, although it is adapted to pro duce stiffeners from any stiff fibrous material. An object is to provide a machine where it will be possible to easily regulate the amount of fiber fed into the same; second, to prop-.

erly wind the same into a flat blade without such winding reducing the bundle of fiber to a cylindrical form, and then providing a mechanical means for delivering the same in this flattened condition into a sewing machine and sewing it all in a continuous operation.

From these statements and the detailed description which follows the complete objects of a machine embodying my invention, the,

driving means for the difierent parts being omitted and the same being reduced to a very simple form for the purposes of the illustration, it being desired to remark that the ma chine in practice will be provided with ten"- sion devices and compensating devices and various expedients and couplings to insure their continuous and satisfactory operation. As my invention does not pertain to these subsidiary devices, I have not illustrated them. Fig. 2 is an end View from the lefthand end of the feeding device, showing the circular aperture for the reception of the fibers in the first instance. from the right-hand side of the feeding device, showing the flattened throat at G for the discharge of the fiber on its way to the winder or flier and presenting an end view of the support H. Fig. i is a detail transverse sectional' view on line 4 .L of Fig. 1. detail view, partly in section, on line 5 '5 of Fig. 1, showing a pair of feed-rolls for compressing the blade and delivering it perfectly flattened to the sewing-machine K. Fig. 6 is a detail perspective view of the finger or support H over which the flattened bundle of fiber is delivered as it is being wound, so that it will preserve the flattened form under such treatment.

In the drawings similar letters'of reference refer to similar parts throughout the several.

views, and all of the sectional views are taken looking in the direction of'the little arrows at the ends of the section-lines.

Referring to the lettered parts of the draw-v Fig. 3 is a view Fig. 5 is a in gs, A is a suitable base on which the various parts of my improved machine are supported. It is not attempted to show these different parts drawn to a scale.

B represents a central standard or bracket which supports a-flier .or winder, the same revolving on a central hollow, spindle O, the

aperture through the spindle being rectangular in cross-section a d; beingformedin an independent core for convenience in manu facture. On this spindle is a revoluble sleeve I on which is the driving-pulley E, and a disk E, which carries a guiding-finger or arm c,-with suitable loops'c c, for .the thread d from the spindle. The spool b is supported on the spindle adj ustably on cones Ct a,so that it will revolve thereon with slight friction.

On the left-hand end of the base A is supported a bracket F on hinge F, adjustable in position by set-screw F. On the front of this bracket is supported a plate I, through which is around perforation having a funnellUU shaped guide I. A pair of feed-rolls J J, with suitable means, as interlocking gears e c and pulley f,for actuating the same,are supported in the upper portion of the bracket. To the right of this bracket F is supported a plate G, having rectangular aperture G, through which the fiber is delivered on its way to the winder, the plate G being suitably beveled away to form a guide into this throat G. A little support H, tapered to a point, is secured just beneath this flattened throat G and extends outwardly a suitable distance therefrom,over which the flattened bundle of fibers passes. The point of this support is so situated as to extend a little distance within the mouth of the aperture of the spindle O, and the winding-thread is delivered in such manner in the winding operation as to embrace the support H at the same time that it embraces the bundle of fibers. This prevents the winding of the thread upon the flat blade of the fiber compressing it into a round cord again. The blade is then delivered through the rectangular aperture in the spindle G, passes out between the delivery-rolls L L at the right hand of the flier, which rolls are also provided with suitable actuating means, as appears in Fig. 5, and with means for putting tension upon the same, so that the flattened blade of stiffening material will be delivered in the best form to receive the row of stitches made by the sewing machine K through the center of its length,which retains the fiber in a flat blade by a single winding and a single row of stitches.

I am aware that it will probably be desirable to provide tension devices between the 'rolls L L and the sewing-machine K, which will avoid the necessity of actuating these two machines at substantially the same rate. An appropriate tension device appears in a satisfactory structure not invented by me, and as such tension devices are not a part of my invention I do not show them here.

The blade when it passes from the sewingmachine can be wound onto a reel M oriotherwise properly taken care of for storage or use. It will be seen that fiber delivered to this ma chine through the throat I, having the circular aperture, can be very evenly fed into the same. The rolls J J then compact the same into a flattened cord or blade, which passes through the rectangular throat Gr over the flat support H. lVhile the flattened cord or blade is passing over this support II it receives a wrappingthread, which also embraces the flattened support H at the same time and is thereby prevented from compacting the same into a round cord again. The blade before it has opportunity to collapse is passed into the rectangular passage of the spindle and drawn by carrying-rolls L L out therefrom and still further flattened or compressed thereby and delivered to the sewingmachine K, where a row of stitches passes down through the center of the same, binding the wrapping-thread securely in place on the flat cord or blade.

The reel M serves a very useful purpose in putting tension on the cord and holding it perfectly flat and straight while the sewingmachine is performing its work and is useful in that way. It is not an absolute essential, however.

I have here produced a machine which performs operations which greatly economize the manufacture of fiat blades or cords from fibrous stiffening material. The structure I have illustrated is largely diagrammatic. There is a great variety of ways of arranging the feed-rolls and of supporting and of driving them. The number of winding devices that can be employed is also very large, and in place of a single thread being wrapped around the bundle of fibers the winder might be double or triple. A single winder, however, is suflicient for the purpose. The blade might be delivered from this winder direct to the sewing-machine without the compression-rolls L intervening, but they are found to serve a very useful purpose. The sewing-machine can be of any variety. These different parts can be geared to operate in unison or can be separately operated, so I have not shown gearin gs for connecting the various parts, as that would be readily accomplished by the skilled mechanic. It is thus apparent that the details of the structure can be greatly varied without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
