This invention relates to embroideringmachines, and especially toa device for suitably connecting to one another the frames ofA two embroidering-machines arranged beside each other in a line.

With this end in view and for the purpose of avoiding counterweights in said machines the frame of one machine in the present invention is so constructed as to form the counterweight of the `other machine. This is attained by arranging both frames upon the ends of levers rigidly connected to one another and placing the supporting-levers of one frame at an angle ofone hundred and eighty degrees in regard to the other, so that when the one frame is lifted the other per' forms a downward movement. By this arrangement counterweights are avoided, so that the attendant has not to operate any dead-load.

In the annexed drawing two embroidering-machines are illustrated in back view provided with the improvementl referred to. Supported upon the main intermediate frame-partition a oftwo embroidering-machines arranged beside each other are both the main girders b. c represents the lother frame-partitions, and d e the two embroidering-frarnes.

Pivoted to the axes f g h are angle-leversft m, t m k, and 7c m. The horizontal arms i of said levers which extend in one direction support the frame d, while their other oppositelydirected horizontal arms c support the frame e. Fixed to the end of said lever-arms i and 7c are rollers lu., adapted to slide in the slot of thereof all the three axesf g h and the levers fixed theretomust perform like movements. The two frames d and e are of quite equal Weight, so that, as stated above, the framed` forms the counterweight of the frame e, and

vice versa, andthe one frame must move upward when the other one is moved downward by means of the pantograph o.

Pivoted to an axis p in the frame-partition a is a two-armed lever g r, provided at its free end with rollers o, adapted to slide in the streets s t, fixed to the frames d and e. -Conf sequently when the frame e is moved by means of the pantograph o to the right the lever r partakes in this movement, and the lever g moves or oscillates quite the same distance as the lever r in the opposite direction, the frame d the right.

I-Iaving now fully described my invention7 I declare that what I claim ispartaking in this movement to 1. In embroidering-machines the combiv nation of two embroidering-machines, each provided with an embroidery-frame, pivotal lsupporting members for said frames and means of moving the one frame an equal dis.- tance as the other frame in opposite direction.

2. The combination of two embroideringframes, connected supporting means therefor causing one frame to act as a counterbalance to the other and effecting synchronous movement of'said frames in opposite directions vertically, and means causing synchronous movement of said frames horizontally.

3. The combination of two embroideringframes, connected supporting means loosely secured to said frames causing one to act as a counterbalance to the other and effecting synchronous movement of said frames in opposite directions vertically, and means loosely secured to said frames and causing synchronous movement thereof horizontally.

4. The combination of two embroideringframes, movably-mounted supporting members therefor connected with each other and causing one frame to act as a counterbalance to the other and effecting synchronous movement of said frames in opposite directions vertically, and a lever connecting said frames and causing synchronous movement thereof horizontall 5. The combination of two embroideringframes, pivotally-mounted bell-crank levers connected with each other and secured .to

TOO

thereof in opposite directions vertically, and

a pivotally-mounted lever connecting adjal cent ends of said frames and causing synchronous movement thereof horizontally.

6. The combination of tWo embroideringframes arranged end to end and provided With supporting streets, bellcrank levers connected with streets at remote ends of said frames, a rocking lever connected With streets at adjacent ends of said frames, rods connecting said rocking and bell-crank levers causing synchronous movement of said frames in opposite directions vertically, and a pivotally-mounted lever connected with streets at the adjacent ends of said frames causing synchronous movement of the same horizontally.

7. The combination of tWo embroideringframes, and means causing one of said frames I5" to act as a counterbalance for the other.

8. The combination of two embroideringframes, means causing one of said frames to act as a counterbalance for the other, and means effecting synchronous movement of 2o said frames.

In testimony whereof I aiiix my signature in presence of two Witnesses.
