ABRAHAM L. COOMBS, OF LYNN, MASSACHUSETTS, ASSIGNOR TO THE IVHEELER do WILSON MANUFACTURING COMPANY, OF BRIDGE- PORT, CONNECTICUT.

TWO-NEEDLE SEWING-MACHINE AND GUIDE THEREFOR.

SPECIFICATION forming part of Letters Patent No. 419,584, dated January 14, 1890.

Application filed April 2, 1889.

To all whom it may concern:

Be it known that I, ABRAHAM L. OooMBs, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Sewing=Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. I

This invention relates to improvements in sewing-machines, and has for its object to provide a two-needle machine having an ordinary presser-foot-as, for instance, a roller presser-footwith an additional presser-foot adapted to serve as a guide for the needles to prevent them coming in contact with each Other.

My invention consists in the combination, with a presser-foot of a sewing-machine having two closely-adjacent needles, of an independent vertically-movable needle-guide foot having two guide-eyes for said needles, as hereinafter more fully described, and as indicated by the claims hereunto appended.

Figure 1 shows in elevation the needle-bar, presser-bar, and independent foot or needleguide and operating parts embodying this invention, the needle-bar and guide for the needles being in their uppermost position; Fig. 2, a similar View to Fig. 1, the needlebar and guide for the needles being in the lowermost position; Fig. 3, a side view of the parts shown in Fig. 2, and Fig. 4 details of the independent foot or guide for the needles to be referred to.

The frame or arm a of the machine, the needle-bar I), having two closely-adjacent needles 2, the presser-bar 0, (herein shown as having a roller presser-foot,) and means for lifting the said presser-bar are all of usual construction. An independent needle-guide bar at has its hearings in the arm or head a to move parallel with the needle-bar b, and its foot (1 is normally held down upon or near to the work by means of a spring (1', which is interposed between the bearing projection of the arm and the collar, shoulder, or projection (1 secured to or formed upon Serial No. 305,651. (No model.)

- A collar or should er I) is secured to or formed upon the needle-bar b, which, as the latter rises and falls, strikes the under side of the collar or projection d and raises the bar d, and as the said needle-bar b falls the spring d causes the bar cl to fall. The two opposite positions of the needle-bar and the relative positions of the guide-bar d may be seen in Figs. 1 and 2. By this foot it will be seen that the two needles remain continually in the guide-eyes thereof, so that there is no chance of fouling.

I do not desire to limit myinvention tothe means herein shown for moving the needleguide bar or foot, as it is obvious that it may be moved in various ways.

I- claim .1. In a sewing-machine, the combination, with apresser-bar and a foot or presser, of a needle-bar having two closely-adjacent eyepointed needles, andan independent vertically-movable needle-guide bar provided with a needle-guide foot arranged adjacent to said foot or presser and having two eyes for said needles, substantially as set forth.

2. In a sewing-machine, the combination, with a presser-bar and foot or presser, of a needle-bar having two closely-adjacent eyepointed needles, an independent verticallymovable needle-guide bar provided with a needle-guide foot arranged to bear on the work adjacent to said foot or presser and having two guide-eyes for said needles, and means for raising and lowering said needleguide foot, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ABRAHAM L. COOMBS.
