AUTOMATIC BoBBIN-wmniis MACHINE.

Application led January 13, 1922. Serial No. 528,981.

To @ZZ whom it may concern.'

Be it known that I, LUDWIG HAssLER, a citizen of the Republic of Germany, and a resident of Plauen, Germany, have invented certain new and useful Improvements in Automatic Bobbin-Winding Machines, of which the following is a specification.

The present invention relates to an automatic bobbin winding machine and particularly to means for transmitting oscillatory motion to the spindle carrying the thread guides.

With automatic bobbin winding machines, it is known to impart oscillatory movement to the spindle of the thread guides by crank operated gears or eccenter. When using a crank a connecting rod is always required and the latter participating in the oscillating movement produces flying masses which disturb the quiet operation of the machine when in rapid motion. On the other hand when the guides are driven through the medium of an eccenter much friction is produced, the guides easily wea-r out and the movement is also unquiet.

This invention has for its object to obviate these drawbacks and consists in a novel means for transmitting oscillatory motion to the spindle of the thread guides whereby the objectionable iying masses and friction are eliminated and the machine can work with a greater number of revolutions than when using the ordinary transmission means heretofore mentioned insuring the quiet precise winding of the bobbins.

rlhe invention is illustrated more or less diagrammetricallv in the accompanying drawing, in which, Fig. 1 is an elevation; Fig. 2 a top plan view thereof with a part shown in section; and Figs. 3-6 are diagrams illustrating the operation of my machine.

Referring to the drawing more in detail a denotes a gear fixed to the main driving shaft a of the machine and which meshes with the gears b fixed on the bobbin spindles e. `he gear a also meshes with a gear c which forms part of the mechanism for transmitting oscillatory motion to the spindle of the bobbin guides. A justably mounted in the gear c is a member f having a hole o to serve as a socket.

uniform movement necessary for the.

Extending transversely of the gear o is the spindle lo carrying the thread guides d and rotatively supported at both ends of the pointed supports fn. Embracing the spindle cand pivotallv connected thereto by a pin Z is a forked piece z'. This piece is provided with an arm h, the free end of which is formed to a ball L which engages the socket g so that when the gear c revolves the arm h will swing in a circle andthrough the forked piece i impart oscillatory motion to the spindle c (Figs. 4 and 6). The mem'- ber-f may be displaced in the gear c and locked in position bv a set screw m (Fig.` l), the displacement aording an adjustment of the socket a nearer to or farther from its central position, in order to cause the arm 72, to describe a larger or smaller circle and therebv control the stroke of the thread guide according to the particular bobbin length.r There may be several thread guides on the spindle c according to the number of bobbin spindles used.

What I claim isz- 1. ln an automatic bobbin-winding machine, the combination with a thread guide spindle and a driven gear, of a member pivotally connected at one end to said spindle and fixed to the face of said gear by a uni- 1 versal joint, so that during the rotation of said ,gear` one end of said member will swing in a circle around the axis of said gear and cause the other end to oscillate said guide spindle.

2. In an automatic bobbin-winding machine, the combination with a thread guide spindle and a driven gear. of a member pivotally connected at one end to said spindle, a radially adjustable socket in the face of said gear, and a ball joint at the opposite end of said member borne in said socket, so that during the rotationof said gear, said member will move in a conical plane and thereby cause said spindle to oscillate.

3. In an automatic bobbin-winding machine. the combination with a thread guide spindle and a driven gear, of an arm formed at one end to a fork embracing said spindle and pinned thereto and at the op osite end with a ball, a socket in the face o said gear arranged away from the center thereof, and bearing said ball so that during the rotation of said gear, said arm will be caused to describe a conical plane and thereby transmit oscillatory motion to said spindle. and thereby transmit oscillatory motion to 4.
