GEORGE MARION MORRIS, OF OOHOES, NEW YORK, ASSIGNOR OF ONE HALF TO GEORGE A. HOUSE, OF SAME PLACE.

SEWING-MACHINE ATTACHMENT FOR SEWING ON BUTTONS.

SPECIFICATION forming part of Letters Patent No. 289,686, dated December 4, 1883.

Application filed April 18, 1883. (No model.)

To aZZ whom it may concern Be it known that I, GEORGE 1VIARION Mon- RIS, of the city of Oohoes, county of Albany, and State of New York, have invented a new and useful Improvement in Attachments to Sewing-Machines for Sewing on Buttons, of which the following is a specification.

My invention relates to that class of devices which are attached to sewing-machines for sewing buttons to fabric, and which are constructed with mechanism that moves the fabric and button back and forth beneath the vertical traverse of the needle.

My invention consists, as will hereinafter be detailed in the construction of a mechanism that-is combined with the foot-lifter, and

foot of a sewing-machine to swing the foot, and foot-raising mechanism around from be neath the needle'to facilitate the insertion of the button.

' My invention also consists in the construction of a spring-plate button-holder arranged to operate in combination with the presserfoot of the sewing machine, the details of which, as constituting my invention,.will be subsequently described herein.

-My invention also consists in the construction of the end of the vibrating fabric-carrier arranged to operate in combination with the spring plate button holder, the details of which construction, as constituting my invention, will be subsequently described herein.

My invention further consists in the subcombination of the factors employed when performing independent function, as will be stated in the claims.

Accompanying this specification and forming a part of it are three plates of drawings containing six figures illustrating my inven tion, and the parts of a sewing-machine with which it connects, and in all of the figures the same designation of parts by letter-reference is used.

Figure 1 shows a perspective of the mechanism and the parts of a sewing-machine with which the former is connected, a dotted line indicating the position of the foot, and springplate button-holder when swung away from under the needle. Fig. 2 illustrates in a perspective the foot and flat-spring button-holder as removed from the sewing-machine to betraised and swung out.

'ter show the the mechanism employed to swing the foot and button-holder. Fig. 3 shows a side elevation of the foot, buttonholder, and the lever by which the foot is cal section of the parts indicated at Fig. 2, taken on the line w w of that figure. Fig. 5 shows in perspective the end. of the button and fabric-carrier, and the annex A, a cross-- section of the same, taken on the line w 00 Fig. 6 shows the fiat-spring button-holder as detached and disconnected, and the annex'B,

a cross-section taken on the line a of this,

figure.

Fig. 4 shows a verti- The parts of the mechanism and those of the sewing-machine with which they connect are designated by letter-reference, and their function explained as follows:

The letter 0 indicates the sewing-machine table-plate, and E the fabric-carrier, which is actuated to vibrate horizontally by means of a cross-grooved cam on the sewing-machine shaft, a pivoted cam switch-lever, the pivoted lever F, and the pivoted connection made by,

the latter at a with the carrier, the latter being constructed to move between the guide bars I) b, all of which factors constitute the ordinary and well-known parts of a sewing-machine attachment, with the exception of my improved method of constructing the end of the carrier, which will be subsequently described herein.

The letter H designates the sewing-machine auxiliary presser-foot, and e a vertical shank attached at its lower end to the foot, so as to move with the latter, and S indicates a spiral spring surrounding said shank.

The letter G designates a bracket, which at g is shown as connected with the carrier E, so as to move withthe latter, and at its other end this bracket G is constructed with the attached vertical sleeve or cylinder I, within which are placed the presser-foot shank e and the spring S.

The letter K indicates a sleeved cap 'that is pivoted to the top of the shank e, and J a lever to turn said pivoted sleeved cap. On the side of the cap K there is constructed the cam G, and upon the stationary sleeve I the campin at. As thus constructed, when the lever and pivoted sleeved cap are turned around,

the cam O engages with the pin (2, and the shank and connected presser-foot are raised against the force of the spring S.

All the parts thus constructed and employed to raise the presser-foot are the usual and ordinary parts of a sewing-machine, and designed for that purpose, and they are merely illustrated and described to indicate my improvement as applied thereto to swing around the foot after it has been raised in the manner described.

To swing the presser-foot around, so as better to adapt it as I use it, I construct upon the sleeved andpivoted cap K a pin, 0, and upon the shank e the upwardly-extended arm a and connect said arm with the shank e by means of the arm-offset a, and produce in the sleeve I the vertical slot S, and the connected horizontal slot (1 for the vertical and lateral passage of said attached arm-shank and foot as raised and swung around. After the foot, the shank, and connected arm have been raised by the lever J, the cam G, and pin (1, as before described, and the motion of the lever J is continued, the pin 0 on the cap K engages with the adjacent side of the arm a and forces the latter, connected shank, and foot around, the offset a of the said arm entering the horizontal slot (1 where the parts are held in position, as shown at Fig. 2 and by the dotted line (2 of Fig. 1, against the recoil force of the spring S.

The letter O designates a pin placed on the cap K, which is placed a sufficient distance from the pin 0 to engage with the opposite side of arm a when the action of the lever J is reversed, so as to force the arm-offset out of the horizontal slot (1 when the presserfoot and attached parts are returned to position by the recoil force of the spring S.

- The letter D indicates a spring- )late buttonholder that is combined with the auxiliary presser-foot II to hold the button while being sewed to the fabric, and this button-holder is attached at one of its ends, as designated at h, to the under surface of the auxiliary presser foot II at its heel, and at its other free end is in contact with the foot under spring-pressure.

The free spring end of the button-holder plate is constructed with a circular opening, it, having inclined edges, and a slotted opening, n connecting the circular opening with the end of the plate, and forming an outlet therefrom. The slotted opening of is made to be vertically coincident in location to the slot 73 produced in the presser-foot.

\Vith the parts thus constructed and an ranged when a button is placed within the opening it, by forcing down the spring-plate button-holder D the latter forces it up against the under surface of the presser-foot to keep it securely in position, and with the button placed so that two of its eyes .are parallel to the vibratory motion of the carrier E, the fabric being beneath the foot and on the carrier, with the sewing-machine operated, the needle N will alternatingly and in sequence make a puncture in each of the buttoucyes, and thus sew the button to the fabric. When this has been done the sewed button may be drawn from out of the holder-grasp through the opening a".

The letter R indicates a raised ring formed on the carrier E around the needle-opening v, and the object of which construction is to force that part of the fabric immediately beneath the buttonup into the sink formed in the but ton bottom, so as to shorten up and make taut the stitches, and to hold the button firmly in place. WVhen my improved attachment is being used to sew on buttons which have no sink on their under surface, the carrier-plate E may be changed for one made without the ring R.

The foot, as thus adapted to swing around after having been raised, facilitates the proper and easy insertion of the button within the holding mechanism, and as thus held it is readily and securely sewed to the fabric.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
