MACHINE FOR SEWING LOOPED FABRICS.

SPECIFICATION forming partof Letters Patent No. 556,585, dated March 1'7, 1896.

Application tiled January 18, 1892. Serial No. 418,417. (No model.)

To all whom it may concern,.-

Beit known that I, CHESTER MCNEIL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Sewing Looped Fabrics, of which the following is a description, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

My invention relates to improvements in sewing-machines, and particularly to those machines designed for sewing looped fabrics; and it consists in the matters hereinafter described and referred to in the appended claims.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved machine; and Fig. 2 is a view, partly in section, on line Fig. 1.

In the drawings the details of construction of the sewing, trimming, and overseaming mechanisms are the same as shown and described in Letters Patent No. 407 ,286 of July 16, 1889, granted to H. H. Fefel; but it will be understood that as far as the particular sewing, trimming, and overseaming mechanisms are concerned other apparatus accomplishing the same purpose might be substituted for that herein shown. Y

Referring now to the drawings, A represents the main part or frame of the machine attached to a suitable bracket, as A.

1 represents an overhanging arm, herein shown as the goose-neck, and 2 the longitudinally-extending arm which supports the clothplate 3. The main driving-shaft 4 is herein shown as arranged vertically and having bearings on the arm 1 and support 2.

C is the needle-arm lever pivoted to the frame of the machine and actuated from the main driving-shaft by the usual system of eccentrics and connecting-rods. Connected to this arm C, so as to reciprocate simultaneously and in a longitudinal direction, are the needle-bars 14 and E, carrying, respectively, the ordinary straight-sewing needle a and the oif'erseaming-needle b. The lower end of the main shaft 4 carries a looper 5 and also an eccentric, which operates a horizontally-moving plate 7, to which is attached one blade B of a trimmer. Co-operating with this blade B is a second blade B', which, as shown, is stationary. This shaft 4 also carries an eccentric which is encircled by the yoke 15 of a rod 16, connected bya universal joint with a lever D, upon the outer end of which is a looper E, so disposed as to move in oblique directions through the cloth-plate 3. Operated by suitable connections from the main shaft- 4 is a rock-shaft F, through which motion is communicated to a spreader-hook G, the same having its points so disposed that at a proper time it takes a loop of thread from the looper E and conveys it to the path of the reciprocating needle b for forming an overseam on the edge of the fabric.

It is not deemed necessary to further describe the construction of the particular mechanisms for sewing, trimming, and overseaming the fabric, since they are the same in respect to detail as in the patent above referred to, the difference consisting in the various arrangements of parts-that is, in the setting of the parts to operate just at right angles to the positions which they occupy in the patent mentioned.

I will now proceed to describe my other improvements, whereby the machine shown is adapted for use particularly in sewing looped fabrics.

While the support for the rotatable material-carrying cylinder is in the present case a vertical overhanging arm identical with the goose-neck of the machine, and while this construction is possibly preferable because of the greater compactness of the machine and is therefore claimed by me, nevertheless it will be understood that in its broadest sense the invention is not limited to such construction, but the cylinder may be attached to any other portion of the head of the machine or to a separate overhanging arm, bracket, or support. Attached to the overhanging arm (herein shown as the goose-neck or head of the machine) is a cylinder H, having suitable impaling-pins upon which the goods to be sewed are placed. This cylinder is rotated in a hori- Zontal plane from the main shaft 4 through the connecting-shafts and gear-wheels shown IOO in Fig. 1. By this arrangement it can be seen that the material can be placed on the cylinder and fed to the sewing mechanism with the greatest ease.

I represents the presser-foot, which is provided with suitable openings for the passage of the needles a and b and trimmer knifeblade B. Said presser-foot between the trim mer and overseaming-needle b is cut away to allow of the operation of a rotatable brush K, which removes the lint from the fabric arising from the action of the trimmer. This brush is herein shown as mounted on one end of a suitable shaft c journaled in suitable bearings on the throat-plate and having near its opposite end a belt-pulley cl, over which runs a belt e driven from the main shaft 4 through the bevel gear-wheels f g.

Various modifications and changes in the details of construction of the herein-described machine may be made without departing from the spirit of my invention.

It will of course be understood that I propose to use in connection with the cylinder herein illustrated the usual co-operating parts, such as stripping-plates, impaling mechanism, (imc. which are common in machines for sewing looped fabrics.

I claim as my inventionl. In a machine for sewing looped fabrics in combination with stitch-forming mechanisms for straight sewing and overseaming respectively, a trimmer between the two stitch-forming mechanisms, a brush between the trimmer and overseaming mechanism, and a rotatable material-carrying cylinder for holding the material and feeding it into position to be operated upon; substantially as described.

2. In a machine for sewing looped fabrics in' combination with stitchforming mechanism comprising a needle for straight sewing and a needle for overseaming, a trimmerbetween the two needles, a brush between the trim mer and overseaming-needle and a rotatable material-carrying cylinder attached to the head of the machine whereby the material is supported and fed into position to be operated upon; substantially as described.

In a machine for sewing looped fabrics, a main vertical shaft, a vertical overhanging arm, a horizontally-rotatable material-carrying cylinder attached to said overhanging arm, a horizontally-reciprocating needle for forming a straight stitch, a trimmer behind said needle, a second horizontally-reciprocat ing needle for overseaming arranged behind said trimmer and a rotating brush between the trimmer and overseaming-needle; all substantially as subscribed.

In testimony whereof I affix my signature in presence of two witnesses.
