FEEDING DEVICE FOR SEWING-MACHINES.

SPECiPiCATfON forming part of Letters Patent No. 380,008, datedMarch 2'7, 1888.

' Application filed June 3,1886. Serial No. 204,001. (No model.)

To all whom itmay concern:

Be it known that I, ERASTUS WOODWARD', of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new 5 and useful Improvements in Feeders for Sewing-Machlnes, of which the following is a speci-, fication.

My invention relates to work-feedin devices used in machines of the type shown in Letters Patent No. 316,927, granted to me and T K. Keith, April 28, 1885, the feeding device shown in said patent being movable in any horizontal direction, so that it can carry the work in any direction under the needle 5 and cause the stitches to form various designs, as shown and described in said patent, and in }Lett ers Patent granted to me December 14, 11886, No. 354,499. Y

The object of the present invention is to so :mount the feeder in its support that its sermated zfaee willat all times, in the operation (of the machine, have an extended bearing rupon (the \work and be capable of conforming .tto inequalities in the thickness of the particular portion of the work on which it rests, thereby securing certainty in the movement of the work, and consequently in the position or character of the stitches.

I will now proceed to describe my invention,

0 so that those skilled in the art may be able to make and use the same, the invention being particularly set forth in the claims hereto appended. Of the drawings heretoannexed, and form- 33 5--;,r 1g a part of this specification, Figure 1 represents a top plan view, Fig. 2 a side view, and Fig. 3 a vertical central sectional view, of a feeding device and its immediately-attached parts. Fig. 4 represents the head of a sewing-machine of the kind described and illusitrated in the ,hereinbefore-mentioned Letters lPatent with ,my ,feeder operativel y attached \thereto.

rfiimilar letters of ,reference indicate similar partsiinall of -.the,figures.

Mylfeeder is designed, as will be seen by.

reference to the Letters ,Patent hereinbefore mentioned, to operateon the upper surface of the goods to move themdntowar'ious positions in order to form ornamental orembroidering stitches of various patternslordesignsthereon.

In the present instance the feeder o is formed of a plate of metal, having its acting face or under surface roughened or provided with points in the usual manner, and provided with a hole or opening, I), through which the needle works. One edge of the opening I) preferably has a V-shaped projection, b, which bears on the-work close to the needle A, and holds the work while herring-bone stitches extending substantially parallel with the sides of the said projections are being formed.

Ears care formed on the sides of the feeder and project upward therefrom, and by means of these cars and pivot screws or pins 8' the feeder .is pivoted to the ends and between the arms 0 c of a'yoke, y, as shown in Fig. 1. Yoke'y has a stud, d, projecting rearwardly therefrom, by means of which the yoke is pivoted to the shank or support e, so as to rock or turn therein, said shank being secured to a plate, B, which is free to rise and fall in guides on an arm, 0, attached to a longitudinallymovable rock-shaft, D, whereby the desired feed movements are given to the feeder, as shown in Fig. 4, and fully shown and described in the above-named Letters Patent. The pivotal connection of the yoke y in the support 6' being at right angles to the pivotal connection of the feeder with the yoke, it follows that the nature of the connection of the feeder withthe support 0 will be that of a universal .or gimbal joint, so that the feeder will always :be held with its serrated or roughened. face pressed .uuiformlyon all portions of the work immediately under the feeder, and will be capable .of being inclined as may be required to cause it to conform ,to folds or plaits or the inequalities in the thickness of the work, thus securing certainty in the movement of the goods and exactness in the position or character of the stitches.

It is obvious that the character of the cop nection between the feeder and the support,

whereby the feeder may be variously inclined with respect to the support to conform to the work under it, substauti ally as set forth.

2. The combination of the feeder, the yoke having a pivotal connection with the feeder, and the support e, having a pivotal connection with the yoke at right angles to the pivotal connection of the yoke with the feeder, as set forth.

3. The combination, with the feeder a, provided with the ears e, of the yoke y, having the arms 0 a, pivot screws or pins 8, stud, d, and support e, substantially as set forth.

In testimony whereof I have signed my name to this specification,in the presence of two sub- I 5 scribing witnesses, this 1st day of June, 1886.

ERASTUS WOODWARD. Witnesses:

O. F. BROWN, A. D. HARRISON.
