'To all whom it may concern.'

and-improved means for loosening the needle threads prior to their boring holes in the embroidery surface.

The invention is clearly illustrated in the.

accompanying drawing, Which, with the letters of reference marked thereon, form a part of this specification and in which is .shown a side elevation with parts in Avertical transverse section. Y v

Referring to the drawings, a represents in a conventional way the, well-known .embroidery jacquard mechanism. I

:zris the'pie'ce of. embroidery or material to be operated upon.

b is the needle and c the opener or borer.

d is an emery roller, varound which passes the thread carried by the bobbins t suitabiy supported on the bobbin bearer e, the latter being carried by a lever y mounted on the shaft f, on which latter also is mounted the lever lc, which Alatter carries the roller or escalpement d of the thread, all as seen clearly in t e upper part of the ligure.'

The lever 7: has the arm Z, to which is pivotally attached one end of the vertical link g, the ,shifting of which is automatically-done by the jacquard mechanism, or by a Atwolarmed lever a mounted to swing on a holt orthe like m, having one end provided with an elongated slot engaging a pin as on the link g and the other end provided with a similar slot engaging a pinpon the board y, which latter is arranged parallel with the material. i

A spring h fast at one end to the iever .t andfat its other 4end to some iired part of the machine, serves to hold the lever in either position, because the maintaining power in both end positions passes upon one side or the other of the center of motion f of said lever, as will be readily understood.

The upper part ,of the gure shows the position of the parts in the position for embroidering. The lower portion of the figure When thelink g is moved upward, the parts shows the same parts inposition for boring.

are moved into the position shown 1n the j lower part of the figure.y When it is wished to embroideri again, the link is pulled downward.

boringn Fo Lhxis reason, the thread is shown obliqnely stretched downward in the lower portionv ci the ligure, as shown ate". ln the upper part of the figure, the portion of the thread z' is shown as horizontally stretched. ln order to loosen the thread so that the oblique position z" becomes possible, the link is moved and the levers turned on their ivot or shaft f, as will be readily understood? itl/*hat is claimed as new is:-

rlhev embroidery surface must be 'shifted a certain distance downward before ln a device of the character described,

the combination with the embroidering needie and the borer, of bobbin bearers pivotally 'inouned, and means for moving them to and fro in the direction of the material to be embroidered.

Q. ln a device of the character described, the crnnbination with the embroidering neeally nn'i-unted,` levers carrying said bearers means for moving them to and fro in the direction of the-material to be embroidered, and a spring connected to one of the levers at one eiid and at the other end .to a fixed lever in either of its positions.
