GUIDING DEVICE'FOR SEWING- MACHINES.

SPECIFICATION forming part of Letters Patent No. 598,353, dated February 1, 1898.

A li ti fil d December 23, 1898. Serial No- 494,582. (No model.) 7

To all whom it may concern:

Be it known that I, RUssEL G. WooDWARD, a citizen of the United States, residing at Waukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of

' which the following is a description, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon.

Myinvention relates to an improvement in sewing-n1achines, and especially to a construction of presser-foot, throat-plate, and cloth-folding device cooperating with a plurality of needles arranged in such away that a line joining them is at an angle to the line of feed.

The invention consists in the matters hereinafter described, and referred to in the appended claims.

In the drawings which illustrate the invention, Figure 1 is a plan View of a cloth-plate of a sewing-machine, showing my invention applied thereto. Fig. 2 is a side elevation of the same, partly in section. Fig. 3 is a plan view of the throat-plate detached.

Inthe drawings, A represents the clothplate of the machine; '13, the throat-plate; C, V the presser-foot; D, the folder or hemmer, and .E the feed-dog, the last being of wellknown construction.

F F are the inner and outer needles, re-

spectively, and, as shown, are arranged in a vertical plane forming, an oblique angle with the line of feed. I

The throat-plate B is secured to the clothplate in the usual way and has slots for the passage of the feed-dog. It has a raised portion a and openings c c, arranged in a vertical plane forming an oblique angle with the line of feed, and the raised portion 0L of the throat-plate in front of needle F,is cut off at an angle, as shown at 7), corresponding, substantially, to the angle at which the line-joining needles and the. line-joining slots in the throat-plate are arranged respecting the line of feed; or, in other words, the line of the cutoff portion of the throat plate is approximately parallel with a line joining the slots 0 c or the needles F F.

The presser-foot C is secured to the bar 0 in the usual manner and has an upwardlyturned toe d, the base of said upturned portion being formed on an angle corresponding to that of the arrangement of the needle.

In combination withmy throat-plate I do, however, propose to use a cloth-folding guide or hemmer D of peculiar construction. It is provided with a slot 6, registering with the front portion of the slot in the throat-plate through which the feed-dog passes, and its inner end, or that portion adjacent to the needles, and from which the folded or hemmed cloth emerges, is cut off at an angle corresponding to the angle of the other parts described. By so constructing the folder and throat-plate it will be seen that the former may lie up close to the needles, so that each side of the end of the folder is equidistant from its respective needle, and the goods, when passing from the same, will be seized by the feed, and that portion of the fabric which is to be sewed by the hindmost needle will be stitched thereby as soon after its passage from the folder as that portion stitched by the forward needle, thereby preventing the danger g of twisting and distorting the goods, which would exist were the forward needle allowed to make a number of stitches through one part of the goods before the other part had been stitched at all, or were one part of the goods required to be fed a considerable distance after its passage from the folder before it came under the action of its needle.

What I claim is- 1. In a sewing-machine, the combination with a plurality of needles, so arranged that a line joining them is at an oblique angle to the line of feed, of means for holding the goods on the bed-plate,a throat-plate having a raised portion, the front of which is formed on an angle to the line of feed substantially the same as the angle of the line joining the needles, and a cloth-guide, substantially as described.

2. The combination, in a sewing-machine having a plurality of needles so arranged that 9 5' a line joining them is at an oblique angle to the line of feed, a presserfoot, a throat-plate having a raised portion, the front of which is formed at a corresponding angle to the line of feed, and a clothguide having its portion nearest the needles also out ofif at substantially the same angle to the line of feed, substantially as described.

3. A sewing-machine comprising a plurality of needles, so set that a line joining them is at an oblique angle to the line of feed, and a throat-plate provided With a raised portion, the front of which is formed on a line approximately parallel With the line joining said needles, substantially as described.

4. The combination in a sewing-machine having needles so arranged that a line joining them is at an oblique angle to the line of feed,

of a presser-foot having its front bearing extremity formed on a line approximately parallel with the line joining the needles, a throatplate having a raised portion, the front of which is also at an oblique angle to the line of feed, and a cloth-folding device having its portion nearest the needles out off at a corresponding angle to the line of feed; substantially as described. In testimony whereof I affix my signature in presence of two Witnesses.
