i. upon, and the fabric, with the buttons sewed To @ZZ whom, it may concern:

' -Be it known that I, GEORGE D. MCOREEDY, a citizen of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Attachments for SewingIachines to Sew Buttons on Fabrics, of which the following is a specification, reference being had therein to the accompanying drawings and letters of reference marked. thereon. Y y f ,My invention relates to improvements in attachment-s for sewingmachines to sew buttons on fabrics. y

The object of my improvements are to provide means whereby buttons may be'easily and rapidly placed in4 position to be operated on, easily and rapidly; removed or passed along, so as to sew on a series of buttons on the same fabric.

Referring to the drawings, Figure 1 is a plan. Figs. 2 and 3 are elevations. Figs. 4, 5, and 6 are plans of parts of my invention; and Fig. 7 is a plan of a special and specific part of my invention containing a button, N. Similar letters refer to similar parts throughout the several views.

The plate A in Fig. 3 represents a portion of the plate of an ordinary sewing-machine.

To the bar B, adapted to be reciprocated, (see Figs. 1, 2, and 3,) I permanently attach the stud or spindle F and standard D, and to the bar B, I also attach the carrying-plate I,v (see Figs. 1, 2, 3, and 4,) provided with the thread and needle-hole I.

At d, I hinge the lever E, (see Figs. 1, 2, and 3,) and provide the lever E also with a central oblong hole, h, (see Fig. 1,) for the stump F to pass through.

To the outer end of the lever E, I attach the spring presser-plate J, and between the bar B and lever E and around the stump F, I interpose the spiral spring IFI. The object of this spring II is to throw up or return the leverE toits normal position. y

On the upper side of the lever E', I secure upon the stump F the cam-lever G. This eamlever is secured upon the stump F by the retainingpin f, which engages with the cam g upon the head of the cam-lever G.

Upon the outer end ofthe spring presserplate J, I secure the button-gage K, so as to cause the center of the button to come directly 4object of this spring L is to press down and holdflrmly in position the button while being sewed onthe fabric. By the conjoint 4action 65 of the gage K and spring L, the button is held in position while being sewed to the fabric. This position of the button is fully illustrated in Fig. 7, where the button N is placed over the center of the holes I', I, and P and a por- 7o tion of the slot M and against the gage K, and

is held down by the spring L, which spring L,

in Fig. 7, is shown by broken lines.

My attachment is adapted to be reciprocated on the plate A of a sewing-machine through 75 the guideclips C, (only one being shown here,) by any of the well-known methods, (which I deem unnecessary to describe,) asufcient distance to allow the needle of the sewing-machine to alternately enter the eyes aand n of 8o the button N.

The operation of my invention is as follows: The cam-lever G is placed in position so as to allow the lever E and springplate J to bc forced 'up bythe spring H to the position sub- 85 stantially as shown in Fig. 2. The operator places the fabric between the plate I and the presser-plate J, with the place where the butt-on is to be sewed on directly over the hole I in the plate I. It may be well here to observe go that the center of the holes I and Pis placed over the center of the hole I in plate I. The operator then turns the cam-lever to the posi tion shown in Fig. 3. The operation of the pin f and cam g during this last-named move- 95 ment causes lever E and springplate J to' be pressed firmly down upon the fabrica, substantially as shown in Fig. 3. The operator then introduces the button beneath the buttonspring L to the position substantially as shown roo peated.

the vertical needle of the ordinary sewing-ma chine to. enter the eyes n and n alternately, thereby sewing the button fast to the'fabricc.

When it is desired to sew on in a line several buttons on the same fabric, the operator draws the fabric forward inv the direction of theV open slot M asufficient distance. The thread that secures the button just sewed on passes out through the slot M, another button.

is passed in against the gage K, under the button-spring L, and the operation is rapidly re- The gage K maybe made to receive abutton of any desired diameter. Reversing Y ythe lever G to the position shown in Fig. 2

releases the fabric.

By the use of my invention buttons may be very rapidly sewed onigarments, and thebuttons may be placed against the gage K always in the same position. The only care in this Iespect required of the operator is to place the button so the bar of the button n will be crosswise of the machine, as shown in Fig. 7.

Havingrthus 'described myl invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The spring presser-plate J, provided with a perforation, P, for the sewing-machine nee- `dle to pass through, and a slot, M, extending from said perforation laterally for the removal of the fabric, and a spring provided with a 3o perforation for the passage of the sewing-machine needle, and adapted to receive and press down the button upon the plate J, and a gage,

K, to press the button against when inserted beneath the spring, all as set forth and speci- 3 5 fied. Y

. 2. The adjustable lever E, having attached thereto the pressenplate J, provided with a gage, K, perforation P, slot M, and buttonspring L, and so constructed as to be suscep 4o I Vitnesses:
