EMBROIDERING-MACHINE.

Specification of Letters Patent.

- Patented Jam-1917.

Application filed March 5, 1915. Serial No. 12,280.

To all whom it may concern Be it known that I, JosEF GRANz, a subject of the, German Emperor, residing at Plauen, in Vogtland, Germany, in the Kingdom of Saxony, have invented certain new and useful Improvements in Embroidering- Machines, of which the following'is a specification.

For the production of effective and uniform moss or plush-like or similar embroidery work on multiple needle embroidering machines, diverse apparatuses have already been constructed satisfactory result could not be obtained.

The drawbacks which are inherent in the hitherto used apparatuses of 'the kind referred to, are obvi .tted by the present invention, according to which the mossor plushlike naps are formed by the employment of tools that resemble tongs or shears and'are formed each with a pair of opposite ears or mouths adapted to open and close and when closed to engage around the needle and thread and to hold the latter loosely until the formation of the next stitch.

To make my invention more clear, I shall in the following describe one embodiment thereof, which is illustrated in the accompanying drawing wherein similar reference characters denote corresponding parts, Figure 1 being a front view of the device in closed position; Fig. 2 a diagrammatic view of the device in open position; Fig. 3 a side view of the device, and Figs. 4 to 6 illustrating the mode of operation.

In the drawing the embroidering machine is represented by needles 4 and the fabric by the line w-aa The new device consists of a series of implements or tools 2' having the form of tongs or shears and which are fulcrumed to a common shaft or bar 3 extending longitudinally to the machine. The

bar 3 is suitably so mounted in bearings 3 of the machine as to be capable of executing a lateral movement.

The two members of each tool 2 are formed at their lower ends with ears or mouths 1, which in open position of the tools are in the range of the needles 4:. As long as the needles are in the fabric the ears 1 remain closed (Fig. 1). On the retreat of the needles from the fabric the bar 3 will perform a short lateral movement, so that the closed ears 1 having caught the thread 45 will be moved out of the range of the needles permitting the latter to the loops. with which, however, a

; then cl pass into the fabric for the next stitch, (for clearness sake the shears 2 in Figs. 4, 5 and 6 are shown displaced vertically instead of to the sides of the needles 4 When the following stitches are not ordinary stitches but ones that produce loops or naps on the fabric, the needles Wlll move past the ears and enter the fabric. On the needle threads becoming tied to the shuttle threads the ears will open and drop of the needles the shaft or bar 3 will return nto initial position bringing the ears 1 back into the range of the needles. The ears will ose again (Fig. 2) so that the needles during the next'following'stitch will pass through them and the process will be again repeated. The closing and opening of the tongs may be effected by connecting rods 5, 6. The bar or shaft 3 as well as members 5, 6 may be operated by well known means (not shown as for instance such used for operating festoon apparatus, which means may be controlled either manually by the operator or automatically from the jacquard.

From the foregoing it will be clear that the new device as compared with the known old devices, renders the machine not only more efficient because more time is available for the'manipulation of the tools, but also allows the production of a faultless and uniform work, because of-the infallible catching of the threads by the opening and closing ears. Besides, by reason of the threads being loose in the closed ears in contradistinction to the old devices which clamp the threads tightly, the tambour frame maintains its unlimited freedom of movement.

Since various modifications may be made in the construction of my device without departing from the principle'of my invention, I do not wish to restrict myself to the details shown and described;

What I claim and desire to secure by Letters Patent is:

During the retreating movement 1. In an embroidering machine, the comcatch the thread thereof and while loosely holding said thread move it out of the range of the needle, then after the formation of the next stitch drop the formed loop and move back into the range of the needle to catch the thread for the next loop.

2. In an embroidering machine, the combination with the stitching needles, of adevice for producing moss or plush-like embroiderywork, comprising ear-like members of closing and opening and adapted capable to catch the needle thread and hold it loosely out of the range of the needle until the formation of the next stitch.

3. In an embroidering machine, the combination with the stitching needles, of a device for producing moss or plush-like embroidery work, comprising ear-like members capable of closing and opening and of moving laterally relative tothe needles, said earlike members being adapted to catch the needle thread and hold it loosely out of the range of the needle until. the formation of the next stitch.

4. In an embroidering machine, the combination with the stitching needles, of a device for producing moss or plush-like embroidery needle until the formation of the next stitch.

5. In an embroidering machine, the combination with the stitch ng needles, of a device for producing moss or' plush-like embroidery Work, comprising a member extendin longitudinally of the machine and movab e laterally to the needles, .a series of implements formed like shears or tongs and fulcrumed to said member, said implements being each formed with a pair of ear-like members capable of closing and opening and adapted to catch the needle thread and hold it loosely out of the range of the needle until the formation of the next stitch.

6. In an, embroidering machine, the combination with the stitching needles, of a device for producing moss or plush-like embroidery work, comprisin a member movable laterally to the need es and extending longitudinally of the machine and a series 'ofimplements formed like shears or tongs and fulcrumed to said member, said impleinents being each formed with a pair of earlike members capable of closing and opening and adapted to catch the needle thread and I hold it loosely out of the range of the needle until the formation of the next stitch. In testimony whereof I afiix my signature in presence of two witnesses.
