OF MAMARO BUTTON-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 783,073, dated February 21, 1905. Application filed November 25, 1903. Serial No. 182,590.

To (all whomit may concern: I

Be it known that I, THORVALD O. QUIsT, a citizen of the United States of America, and a resident of New York city, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Button-Sewing Machinesof which the following is a specification, reference being bad to the accompanying drawings, forming a part thereof. I

My invention relates to improvements in button-sewing machines, andparticularly to I means employed for locating the position of posed beneath the buttons with respect 'to the goods upon which they are to be sewed.

In sewing on buttons it has been customary heretofore to mark the places upon the goods upon: which they are to be sewed, such marks registering with buttonholes with which the buttons when in position are adapted to engage. This marking takes time, and, further,- the marks are sometimes wrongly placed, and, again, the buttons are sometimes sewed onto the goods in positions out of register with such marks.

In my present invention I have so arranged that that portion of the goods containing the buttonholes may be superposed upon the portion of the goods upon which it is desired to sew the buttons and have provided means for receivingthe two pieces of goods so superbutton-clamp and have provided means for forcingthe buttonholes open when in the sewing position, so that the buttons arranged for engagement with said buttonholes may. be sewed to the goods through the open buttonholes.

The result of my invention is to cause the buttons and buttonholes to always correctly register and to avoid the expenditure of time formerly employed. Y

A further result of my invention is to deliver the goods in a buttoned-up conditioiwithout further operation. 'Heretofore it has been necessary to expend time in buttoning up the goods by hand when it has been desired to deliver the goods in such condition. To accomplish the foregoing,'I provide a button-sewing machine with an expandingdevi'ce button-clamp may then be comprising two relatively movable claws located immediately beneath the button-clamp. These claws are adapted to engage or hook over the sides of a bnttonhole, so that when moved apart they will force the sides of' the buttonhole open to expose the material beneath same.

rial beneath the buttonhole. the stitches for sewing same passing-freely between the sides of the said buttonhole.

Myv invention further consists in certain novel details of construction and combination of parts, as will hereinafter more fully appear.

I will now proceed to describe mechanism embodying my invention and will then point out the novel features in claims.

In the drawings, Figure l is a View in side elevation of a button-sewing machine includingmechanismembodying myinvention. Fig 2 is an end view of same. Fig. 3 is a par tial end view and a view partially in vertical section through the button-clamp and buttonhole-expanding device. Fig. 4 is a detail top view, on a somewhat-enlarged scale, of certain portions of the machine, showing the buttonhole-expanding device in operation, certain parts being broken away in order to illustrate better the various features of construction and operation.

In the drawings I have shown a conventional form of button-sewingmachine comprising the usual bed-plate 1, overhangingarm 2, and front head 3. Stitching mechanism is represented by the needle-bar Ki, carrying a needle 5 and looping or shuttle mechanism 6. 7 designates "a combined work-support and button-clam p as a whole. This work-support and button-'clamp comprises a carrier 8, a plate .9, an overhanging arm 10, pivoted to the carrier at 11, and a button-clamp 12. N cc- A button inserted into and held by the sewed to the mate essary movements are imparted to the carrier 8, and hence to the for shifting the work-support and buttonclamp for presenting the button and material to which it is to be sewed in the proper stitching positions. The particular mechanism for imparting these movements is not illustrated in detail herein, being well known in the art parts supported thereby,

. 3 of the machine.

' stated are then placed and forming no part of the present invention. The plate 9 is'secured to the carrier 8 and forms a "support for the material operated upon. The button-clamp-12 comprises an upper rigid plate 13 and a lower spring 14 and constitutes not only a button-clamp, but also a top or presser member for the work-clamp. 1n thedrawings a buttoii is'shown in the position between the upper and lower plates of the work-clamp, such button being designated by referencecharacter 15. The arm 10 is provided with an extension 16, to which a link, cord, or chain 17 'is connected. This link, cord, or chain may connect with a treadle or other operating means whereby the arm may be rocked upon its pivotal support 11 to raise and lower the button-clamp. A spring 18 operates to move the parts in opposition to pressure applied through the link, cord.0r chain 17.

An expanding device is arranged beneath the spring-plate 14 of the button-clamp 12, such expanding device comprising two relatively movable claws. In the present embodiment of my invention 1 have shown one of the claws, 19, as stationary with respect to the button-clamp. The other claw, 20, is secured to a sliding plate 21, mounted to slide in guides upon the upper plate 13 of the button-clamp 12 and spring-actuated, by means of a tension-spring 22, in one direction. A bell-crank lever 23, fulcrumed at 24: upon a support 25, secured to the button-clamp plate 13, has one of'its arms in engagement with the said slide-plate 21 and. is arranged with its other arm in proximity to and adapted to be engaged by anabutment 26 upon the head When the button-clamp 12 is lifted, the upper arm of the said bell-crank lever 23 will be engaged by the abutment 26, so that the said bell-crank le ver will be rocked upon its support and will thereby move the plate 21 forward or in a direction towardthe line of movement of the needle. The effect of this movement will be to move the movable claw 20 into line with the stationary claw 19. The'parts are shown in these positions in Fig. 2 of the drawings. hen the workclamp is lowered, the bell-crank lever will be disengaged from the said abutment .26 and the spring 22 will be permitted to draw the plate 21 backward. The result of this, will be to move the movable claw 20 away from the stationary claw 19, as shown in Figs. 3 and 4 of the drawings.

In operation material in which buttonholes have already been made is superposed upon material'toi which it is desired to. attach buttons. The'link 17 is theredepress'ed, lifting the arm 10 and the work-clamp 12,-so as to leave a space betweenthelower side of .the button-clamp and'the upper surface o the plate 9. Tlie'materials superposed as above between'the plate 9 and the button-clamp 12 with a buttonhole longitudinally in .line. with'the down wardly-probutton-clamp,

jectingportions of the claws 19 and 20, and then slightly lifted, so as to cause the said claws to engage the sides of the buttonhole.

Tension upon the link 17 is now released,per-

mitting the arm 10 and button-clamp to descend, clamping the work between the button- .clamp and the plate 9 and a t ..th'e same time moving the claws 19 and 20 apart in the manner above stated. A button being now inserted between the plates 13'and 1a of the buttonclamp,the button may be sewed to the lower of the two materials.the stitches passingfreelv between the sides of the buttonhole thus held apart. Figs. 3 and T show the parts after the button-clamp has descended and the expanding device has opened the buttonhole ready for a sewing operation.
