GEORGE IIELLIAR COLLEY, OF JACKSON, MICHIGAN, ASSIGNOR TO THE IVEEKS COLLEY MANUFACTURING COMPANY, OF SAME PLACE.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 549,184, dated November 5, 1895.

Application filed July 10, 1894.

To all whom it may concern.-

Be it known that I, GEORGE HELLIAR COL- LEY, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Sewing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to sewing-machines, but more particularly to two-needle or multiple-needle machines of the rotating-shuttle type, such as disclosed in the Letters Patent granted to me November 14, 1893, No. 508,600.

The invention will first be hereinafter more particularly described with reference to the accompanying drawings, and then pointed out in the claims at the end of the description.

Referring to the accompanying drawings, forming'a part of this specification, Figure 1 represents a front view of a shuttle-race and so much of a sewing-machine as is necessary to illustrate the invention. Fig. 2 is a side view of the shuttle-race with the needles and holder arranged above same. Fig. 3 is a sectional plan View on the line III III of Fig. 2, and Fig. 4 is a sectional view on the line IV IV of Fig. 3.

In the drawings, A denotes the work-plate of the sewing-machine; B, the overhangingarm of the frame or goose-neck which supports and guides the needle-bar O and pressure-foot bar D.

c c are the needles arranged upon an arm or needle-holder having the usual needlesockets and socketed head to receive the needle-bar and provided with a lateral extension 0*, so as to set the needles carried thereby in line with the needles in the usual needlesockets. Secured upon said extension 0 by the set-screws 0 are the sliding clips 0 0 having sockets and set-screws, as shown, for the attachment of the needles. D is the pressure-foot bar, and d the pressure-foot carried by said bar.

The parts as thus far described are of the usual or well-known construction in rotatingshuttle machines and may be operated in the usual way, or they are such as disclosed in Serial Nb. 517,046. (No model.)

my aforesaid patent, and therefore further description thereof herein is not deemed necessary.

E is the raceway arranged below the needle-holder C in any suitable manner, and preferably consists of separate circular sections E and E though this number may be varied, if desired. The section E is stationaryand may be of the ordinary construction, but is preferably of the improved form shown and is provided with studs 6 and e, on which the section E is adjustably held. These studs have one'end of each secured to the section E and the other ends passed through apertures in the section E on which the said sections are slidingly held. The stud 6 may be provided with a head 6 on the outer end thereof to limit the movement of the section E the said section carrying a set-screw 6 adapted to engage said stud and by which the section may be adjusted and held in the proper position. Each section is preferably provided with two races 6 and e and has on the outer surface thereof a plate 6 which serves to retain the shuttles in the races 6 The inner portion of each section is provided with a circumferential recess or slot to receive a segment .G, the said segment being pivotally secured in said circumferential slot by the pins or screws g and each provided with a circumferential slot or guide-groove g in its inner curved surface, which coincides with the groove 6 to form a supplementary race in said section. The segment G may be thrown downwardly on its pivot by the knob or button g secured to said segment, as shown in dotted lines in Figs. 2 and 3. Each segment is held in a raised position by a sliding pin 1 or plunger h engaging an aperture 9 of said segment. This plunger is held within a sleeve h, which is secured to and extends outwardly from the section. The plunger is normally pressed inwardly by a spring 7L surrounding the stem of the plunger 7; and arranged within the sleeve It. On the sleeve is arranged a projection or pin 7L3 engaging a slot h of the handle 7L To remove the shuttle from or insert a shuttle into one of the races having the hinged segment, the operator, by pulling the plunger h against the tension of the spring h and disengaging it from the aperture of the segment, will permit said segment to be thrown on its pivot, as shown in dotted lines in Figs. 2 and 3, by a downward pull upon the knob or butten 9 The plunger may be retained in a disengaged position by simply pulling the same outwardly by its handle and then slightly turning said handle, so as to prevent the slot 7L from registering with the pin it shown in dotted lines in Fig. 3. After the insertion or removal of the shuttle the segment may be raised and the handle turned to its normal position, at which time the pin 7L3 and slot 7% will register, when the recoil of the spring 71,

will throw the end of said plunger into engagement with the aperture of said segment, thereby rigidly holding the same.

I desire to have it understood that I do not wish to confine myself to the exact construction shown and may vary same in some instances without departing from the spiritof section so as to form a supplementary race,

and means for opening and closing said segment to permit the insertion or removal of an additional shuttle,substantially as described.

2. In a rotating shuttle sewing machine, the combination of a multiple shuttle-race co1nprising a stationary and an adjustable section, the latter being provided with a circumferential slot, a segment fitting said slot provided with a guide-groove coinciding with a groove in said section to form a supplementary race, and means carried by said section for opening and closing said race to permit the insertion or removal of an additional shuttle, together witha needle-bar and the needleholder supporting the adjustable needle-sockets, and means for securing the latter in various positions, substantially as described.

3. In a rotating shuttle sewing machine, a multiple race comprising two or more sections adjustable with relation to each other and provided with .a pluralityof interior circular guide'grooves or races, each section having a circumferential slot, a segment fitting said slot and provided with a guide-groove coinciding with a groove in the section so as to form a supplementary race, and means carried by said section for securing the segment in said circumferential slot, substantially as described.

4. In a rotating shuttle sewing machine, a multiple race comprising two or more sections adjustable with relation toeach other and provided with a plurality of interior circular guide-grooves or races and with a circumferential slot, a hinged segment fitting said slot and provided with a guide-groove coinciding with a groovein the section so as to form a supplementary race, and a spring: pressed pin carried by the section for lockin g said segment within the slot, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE l-IELLIAR OOLLEY.
