BOBBlN-WINDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 268,773, dated December 5,1882.

Application filed March 10, 1882. (Model) To all whom it may concern Be it known that l, STANISLAW B. GABaY- ELSKI, a citizen of Germany, residing at Cleveland, in the county of (Juyahoga and State of 5. Ohio, haveiuvented certain new and useful Improvements in Bobbin-Winders for Sewing,- Machines; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled to in the artto which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, in which- I Figure l is a front elevation of the bobbinwinder attached to a sewing-machine and ready for operation. Fig. 2 is a side elevation of the same, showing in dotted lines the position of parts when the bobbin has been filled 2o andthe'friction-wheel thrown out of contact with the balance-wheel. Fig. 3 is an isometrical projection of the prop. Fig. 4: is a bottom view. Fig. 5 is a vertical section taken upon the line at m of Fig. 1. Fig. 6 is an isometrical projection of the notched bobbin. Fig. 7 is an end elevation of the live-center, showing its catch. Fig. 8 is anisometrical projection of the stop that operates the prop. Fig. 9 is an elevation of the lower end of the 0 thread-arm,showing-the adjusting-slots. Fig. 10 is an isometrical projection of the bed-piece.

My invention relates to that class of devices used in transferring thread from an ordinary wooden spool to the bobbin of a sewing-nia- 5 chine shuttle, and has for its object an improvement of construction and the production of an automatic device that will stop the winding of thread as soon as the bobbin has received the required amount; and it consists in,

0 the construction and combination of parts, as

will be hereinafter more fully set forth.

In the accompanying drawings, Arepresents a rigid frame, which may be secured to a sewlug-machine by any suitable means, care being 5 taken to so locate it that the friction-wheel which it bears may be brought into contact 'with the face'ot' the balancewheel B. The frame is shown in this application secured to an arm, 0, of the standard which sustains the hearing of the balance-wheel by means of a screw passing through an upturned lug and into the arm.

D represents a bed'plate, hinged to an arm,

E, of the frame A, so as to have a limited vertical movement, to which are secured the operative parts of the thread-winded F represents a vertical standard, located at one end and forming a part of the bed-plate D, which affords a bearing for the shaft that carries the friction-wheel G on one end and the revolving or live center H on the other.

To the opposite end of the bed-plate is seecured by any suitable means a spring-bar, I, which carries the center J at its top. Between the centers H and J the bobbin K is held 6 pressed into the live-center by the spring-bar I, and there held for a rotary movement by a catch entering a slot in the end of the bobbin.

Between two backwardly-projecting lugs, L and M, of the bed-plate D is hinged a springstop, N, that is held in against the side of the bobbin by springs 0 and '1, attached to the bedplate and the stop. The stop hasa projecting thumb-picce, P, that is used in moving the stop by hand, and that rests against the curved side of a prop, Q- The prop Q consistsot' a slotted bar held to the bed-plate by headed screws, upon which the prop has a limited play, and is provided with a vertical projection havingacurved side atits upper end resting against the side of the thumb-piece P, where it is held by a spring, B,.secured to the bed-plate. and the end of the prop.

The lower edge of the prop Q has a projection, S, for resting upon the projecting arm U 8 of the frame A when the winder is in service.

To the back ends of thelugsLandMathreadcarrier, V, is secured by two headed screws passing through slots, by means of which it is rendered vertically adjustable, andclamping the lower end of the carrier to "the lugs. A suitable distance above the slots, so as to be in a proper position with regard to the bobbin. the thread-carrier is provided with an oblong slightly-curved aperture, W, extending across the carrier, with a length equal to 'the length of the shuttlebobbin. 'Immediatelyabove the aperture W the carrier is contracted to a narrow strip ot'metal, that may extend any required distance upward. Near its upper end it is pro- 2 v scares vided with a slot, X, extending diagonally downward from the edgeto the center of the carrier, where it terminates in a circular openingfor the reception of the thread. A suitable distance above the slot X a slot, Y, extends from the opposite side of the carrier diagonally downward to the center of the carrier, and terminates in a circular opening for the reception of the thread.

A spring, Z, is attached to the carrier by an adjusting-screw, a, a suitable distance below the inner end of the slot X, and extends by means of a slight curve to the intermediate point between the inner ends of the two slots, Where it rests upon the carrier. By tightening or loosening the screw it the spring can be made to exercise greater or less pressure, and thus control the tension of the thread passing beneath it.

In threading the carrierthethreadbispassed from the back side of the carrier to the bottom of the slot Y, then to the bottom of the slotX, passing under the spring Z, then down back of the carrier to the aperture, through which it is passed to the bobbin, n here it is wound.

The bobbin being empty and the end of the thread attached to it, the spring-stop N is let up against it, and the bed-plate is raised until the frictiorrwheel comes in contact with the face of the balance-wheel. This movement raises the projection S of the prop above the arm U of the frame, which permits the spring It to throw the prop in until the curved side of the vertical projection rests against the side of the thumb-piece of the stop and brings the projection S over the top of the arm U, upon which it rests and holds the friction-wheel in gear. As the thread is wound upon the bobbin the stop, which maintains a steady and constant pressure upon the thread, thereby regulating its even winding, is forced out from the bobbin, and, pressing against the curved side. gradually pushes the prop to one side, until at the moment the bobbin is full the prop passes off of the arm and the plate falls upon the arm, carrying the friction-wheel away from contact with the balance-wheel, thereby discontinuing the winding.

Having thus described my invention,Iclaim as new- 1. In a bobbin-Winder for a sewing-machine, the combination of theframe, prop, spring-stop, bed-plate, and friction-wheel, substantially as shown and described.

2. In a bobbin-winder for a sewing-machine, the combination of the frame, prop, bed-plate,

spring-stop, and bobbin, all arranged and opcrating to lower the bed-plate at the moment the bobbin is filled, substantially as shown and described.

3. The combination of the frame A, prop Q, spring R, and bed-plate D, whereby the bedplate is raised and lowered, substantially as shown and described.

4.. In a bobbin-winder for a sewing-machine, the thread-carrier V, provided with slotsY and X, and spring Z, with adj usting-screw a,whereby a required tension may be obtained, substantially as shown and described.

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