IMPROVEMENT IN SEWING-MACHENES.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may concern Be i'tvkn'fown that we, JAMES NnALn and Pagen BECK, both ofthe city of Bridgeport, in the county of Fairfield, and State of Connecticut, have'invented a new and useful Improvement in Sewing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the construction, character, and operation of the same, reference being had to the accompanying drawings, which make part of this specification,- in Which- Figure l is a perspective view of the outer end of the vibrating lever, or needle-bar, showing a section of the needle-bar, needle, foot-piece, and guide.

Figure 2 is a plan of a section, cut vertically through the stud by which the needle is attached to the needlebar, showing the socket, or collar by which the needle is secured or attached.

Figure 3 is a perspective view, enlarged, of the socket, or collar which binds the needle, when tightened by the nut or female screw.

Our improvement consists in attaching the needle to the end of the needle-bar, by a loose stud working in a guide, so that the point of the needle will always be moved 'in the same direct line, without reference to the curvilinear motion of the vibrating end of the needle-bar, which will enable us to use a straight needle in any kind of sewing-machine.

.lhe object of 'our invention is to enable machines, having curved needles attached to vibrating arms, to use straight needles, and this we accomplish by attaching a straight needle to a loose stud in the vibrating arm, which is revolved partially at each vibration of the arm, and in this way keeps the needle always in a vertical position.

0n, or outside of this stud a, we place a socket, or

collar,.as shown in tig. 3, and indicated at c c, iig. 2, with two notches in its end, asshown at g g, g. 3, to

steady the needle in its place, so that the stud a mayV play freely in the end A of the needle-bar, to allow-the rectilinear motion of the needle.

And we make the rear end of this stud asquare, or oblong, in its cross-section, so that it may work freely but accuratelyin the vertical rectilinear guide d, so

as to keep the4 needle bin the same vertical plane, vwithout reference to the curvilinear motion of the vibrating end A of the ,needle-bar, as the 'guide d will control the direction of theneedle.v

` On the front portion of the stationary bar B, which sustains the foot O, We fit a vertical guide made with parallel sides, as represented at d, iig. 1, to receive and guide or control the inner end e of the stud a, which will keep the needle b in its vertical plane, all as indicated in gnl.

The advantages of our improvement consist in that by the use of the loose stud a, with its square end e, and the guide d, we are able to use the straight needle b with the needle-bar, whose vibrating end has a curvilinear motion.

What we claim as our invention, and desire to secure by'Letters Patent, is

The combination of 'the loose stud a and straight needle b with the parallel, or rectilinear guide d and needle-bar-A, when they are constructed, arranged, and iitted for use, substantially as herein described and set forth.
