EYELET-HOLE ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 270,696, dated January 16, 1853.

Application filed November 13 1882. (Xo model.)

To all whom it may concern:

Beit known that I, CALVIN E. RANDALL, of Natick, in the count-y of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Eyelet-Hole Attachments for Sewing-Machines, of which the following, taken in connection with the accompanyin g drawings, is a specification.

My invention relates to an attachment to be the purpose of simplifying the operation and reducing the expense of Working eyelets by machinery; and itconsists, first, of a gage-pin connected to and arranged to revolve about the needle with the cloth-carrying mechanism, and adapted to gage the distance of an eyelet from the preceding one.

It further consists in an adjustable pin connected to and arranged to revolve about the needle with the cloth-carrying mechanism, and adapted to determine accurately the distance of one eyelet from a preceding one, as .will be more fully described.

My invention is illustrated in the accompanying drawings as applied to the eyelet-Working sewing-machine shown and described in the Letters Patent No. 227 ,640, granted to George M. Morris, May 18, 18805`but it may be applied to any eyelet-workin g machine with equally good results.

In the drawings, Figure 1 is a perspective view of the Morris machine above referred to with my improvement attached thereto.

Fig. 2 isv a partial sectional plan of the same, drawn to an enlarged scale. Fig. 8 is a vertical section on line a: on Fig. 2, with my attachment revolved one-fourth of a revolution around the needle from the position shown in Fig. 2, drawn to a. still larger scale. v Figs. 4 and 5 are respectively a plan and an elevation of my attachment; and Figs. 6 and 7 represent modications of my attachment and the manner of connecting it to the ratchet feed- Wheel.

As the sewing mechanism of the machine illustrated is constructed, arranged, and operates in precisely the same manner as described in the Letters Patent to Morris before cited, and as such'mechanism,per se, forms no part of 5o myinvention, it need not be described here further than to make clear the connection therewith and the operation of my attachment.

applied to eyelet-Working sewing-machines for I Will now proceed to describe my invention and its application to the machine illustrated, and in order that persons skilled in the art -mayclearly understand its application, I will first refer to such parts of the machine as are necessary to a clear understanding of my invention.

A is a circu'ar feed-ring or annular disklike plate, provided with ratchet-teeth upon its periphery, and mounted upon the Worksupporting plate B,and within a circular opening in the plate C, secured upon said plate B, and having a portion of its outer edge covered by the annular plate D. The Work-supporting plate B is connected to the bar E, to which an intermittent reciprocating motion is imparted by suitable mechanism for the purpose of causing the formation of the over-edge stitches, and the leed-ring A is intermittently moved about its axis and the axis of the needle by the pawl a, pivoted to and operated h v the reciprocating bar b. The inner edge of the feed-ring A is curved, as shown, and its annular hat up'per surface is provided Witha circular series of sharp needle-like points or spurs, c c, as shown in Fig. 3, upon which the fabric is placed in such a position that the spur or bodkin d shall puncture the same at the point where it is desired to form an eyelet as the fabric is forced down thereupon by Y gage-pin g, adjustably secured to the arm h,

which in turn is secured to the upper side ot' the feed-ring A, so as to revolve about the needle and be reciprocated toward and from the front end of the machine therewith.

For use upon the particular machine shown and described, I prefer tov make my gage in the form shown in Figs..4L and 5, in which the arm his shown as projecting radially from and forming a part of the annular plate 71.', in which are formed a series of small holes, i, corresponding in number, size, and location to the series of spurs c c, set in the upper side of the feed-ring A', so that by inserting said spurs c c in the holes i z' and pressing the ring h down hard upon the upper surface of the feed-rin g A the gage will be secured to said feed-ring sufliciently to insure its revolution therewith and the proper registering ofthe work.

The pin g is formed with a shoulder to re-st upon the upper side of the arm h, which is slotted, as shown,to receive the shank or reduced portion, and is secured in any desired position in said slot by means of a screw or nut, fi', Jfitted thereto and adapted t bear upon the under side ofthe arm 7L, as shown in Figs. 3 and 5.

If desired, the annular plate It may be dispensed with, and the arm h may be secured directly to the feed-wheel A by means of the screws jj, as shown in Fig. 6, without affecting the principles ot' my invention. Again, the pin g may be tixed in the arlnh, and said arm may be pivoted to the feed-ring Aby the screw 70,' so fitted that it may clamp the arm l1, to the ring in a radial or a tangential position, as shown in Fig. 7and still maintain the same general features of myinvention-viz., a gage pin secured to and movable with the feeding apparatus, and adapted to be adjusted toward and from the axis ot' motion ot' said feed mechanism.

1n working eyelets by machinery as hereto- A work, the pin g having previously been adjusted and setat the proper distance from the center of the feedring.

What I claim as new, and desire to secure by Letters Patent of the United States, is

l. In combination with an eyelet-worliing mechanism, a gage-pin connected to and adaptf ed to revolve about the needle with the clothcarrying mechanism, substantially as and for the purposes described.

2. In combination with an eyelet-working mechanism, anladjustable gage-pin connected to and adapted to revolve about. the needle with the cloth-carrying mechanism, substantially as described.

3. In combination with the feed-ring A,pro vided with the spurs c c, a gage for determining the distance between twoeyelets,composed of the pin g, arm h, and the annular plate h', provided with the series of holes t' i, substantially as described.

In testimony whereof [have signed my name to this specificatiomin the presence ot'two subscribing witnesses, on this 10th day of November, A. D. 1882.
