Improvement in Sewing Machines.

iMPROVEMENT EN SEWING-MACHINE$.
Specification forming part of Letters Patent No. 115,656, dated June 6, 1871.
To all whom it may concern:
Be it known that we, HANNAH G. SUPLEE and J on): H. MooNnY, of San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improveinent in Sewing-Machines; and we do hereby declare that the following is afull and exact description of the same, reference being bad to the accompanying drawing and to the letters of reference marked thereon.
This invention consists of athread-holder, adapted to hold the upper end of the outer line of the bight of the thread (while the bight is being drawn by the hook over the bobbincase) in a line parallel, or nearly so, to the line traversed by the needle,at a point removed from said line about the width of the bobbin-case, as will be fully described hereinafter.
In the drawing, Figure 1 represents a side elevation of a machine having our improvements attached thereto; and Figs. 2, 3, 4, 5, 6, 7, 8, 9, 10, and 1l,views of parts detached.
To enable others skilled in the art to make and use our invention, we will now proceed to describe fully its construction and manner of operation.
The invention in this. application is shown applied to a machine having an elliptic hook.
A represents the cloth-plate B, the bobbin-holder, holding the bobbin 1); O, the looper or hook,wl1ich is provided with a slot, 0, upon one side; and D, a finger-hook, located upon the lower side of the cloth-plate. The hook or plate D is arranged upon the cloth-plate in such relation to the hook G that the latter, in its revolution, passes above and below the projecting end of the former by means of the sides of the slot 0.
The operation is as follows: As the needle begins to ascend the loop of the thread is caught by the hook G in the usual well-known manner, and by its revolution is carried about the bobbin-case. As the book 0, however, passes the finger-plate D, the outer line of the bight or loop is caught by its recess d, in which latter it is held untilthe loop is discharged from the hook C. By means of this construction the loop of the thread is held as follows: Its inner line is held at the upper end by the needle and at the lower by the inner edge of the hook C, while its outer line is held at the upper end by the finger-plate D and at the lower by the outer edge of the hook O, the sides being united by the thread lying in the groove of the hook. It therefore follows that we are enabled to form .the thread-loop with parallel I sides, or nearly so, the width between the sides being determined by the width of the hook O and the relative position of the fingerplate D; It will be perceived that by this means we are enabled to pass the thread over the bobbin-case without 'undue friction upon any part, and also that we can use, if desired, a very large bobbin. A large bobbin is shown in the drawing,the holder of which is adapted, as shown, for its reception.
In practice it may not be necessary to hold the outer line of the thread-loop at a point as far away from the line traversed by the needle as would be indicated by the width of the bobbin-case. We therefore do not limit ourselves to the precise point at which the thread may be held.
Having thus fully described our invention,
what we claim as new, and desire to secure by [L s.] JOHN H. MOONEY.
