EMBROIDERING-MACHINE ACCESSORY.

Specification of Letters Patent.

Patented July 8, 1913.

Serial No. 703,037.

To all whom it may concern:

Be it known that we, EMIL Mnr'rnnn, S12, a citizen of the Republic of Switzerland, and residing at Gossau, Switzerland, and EMIL METTLER, Jr., a citizen of the Republic of Switzerland, and residing at Romanshorn, Switzerland, have invented certain new and useful Improvements in Embroidering-Machine Accessories; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

When embroidering large patterns as garments or the like which in their whole extension can be embroidered only by repeatedly reeling the fabric up, it happens, that when after completing a part of the pattern and the fabric is reeled up, the latter is distorted in lateral direction so that the portion of the fabric continuing the completed portion of the pattern does not exactly join this portion but is somewhat spaced therefrom. Also during the embroidering proper, as for instance in the perforating or punching, the fabric is unfavorably distort-ed in lateral direction, so that at all events the neat appearance and the accuracy of the pattern is diminished and in many cases repeated em broidering becomes necessary.

The object of the present invention is a device for the use in handor shuttle-embroidering machines, for preventing the fabric from being distorted by the embroidering or reeling.

In the accompanying drawing the inven tion is illustrated by way of example.

Figure 1 is a rear elevation showing parts of an embroidering machine with a device according to this invention. Fig. 2 is a side elevation of the device. Figs. 3 and 4 are cross sections, showing the same at different working positions.

The device comprises two wooden bars a and b, which are connected together by hinges 0. Each bar is provided outside with pins d which are arranged at distances equal to the designs. The pins of the bar a project at right angles to the surface of the bar (Figs. 3 and 4) while the pins of the bar 6 are rearwardly directed. The bars can be turned to form an angle with each other (Fig. 3) or to be stretched out in the same vertical plane. In order to secure the bars in the latter position, a latch c is pivoted to the bar 7), which latch is mounted to engage the head of a screw f in the bar a (Figs. 2 and 4).

The device when used is mounted above the surface to be embroidered and parallel to the fabric rollers. In order to attach the device to the fabric, the bars are moved into the angular position shown in Fig. 3. Firstly the pins of the lower bar Z) and hereafter the pins of the upper bar a are caused to penetrate the fabric. Then the bars are moved into the position shown in Fig. 4 and secured in position by means of the latch a. By turning the bars into this position the fabric is maintained stretched in a vertical direction. The device remains in this position during the embroidering and the reeling operation and prevents the fabric from being distorted in the horizontal direction of the machine, the pins cZ fixedly holding the fabrics. As soon as the bars arrive near the fabric rollers, they are released from the fabric and displaced. I'Vhen removing the device the operations are performed in a succession reverse to that first described.

Of course several such devices are necessary for each story of the machine, the devices for each story being arranged side by side in a horizontal row. The single devices may be of any suitable length and the devices may at their joints simply oin or overlap each other or they may be connected in any suitable manner.

We claim 1. In a device for preventing the distortion of the fabric in embroidery machines, a pair of rails directly flexibly connected at their proximate edges and provided with pins at their opposite edges for penetrating the fabric and holding it from distortion under all conditions of operation of the embroidery machine.

2. In a device for preventing the distortion of the fabric in embroidery machines, a pair of rails directly flexibly connected at their proximate edges and provided with pins at their opposite edges for penetrating the fabric and holding it from distortion under all conditions of operation. of the embroidery machine, and means for holding the rails in engaging position with the fabric.

3. In a device for preventing the distortion of the fabric in embroidery machines, a pair of rails directly flexibly connected at their proximate edges and provided with pins at their opposite edges for penetrating the fabric and holding it from distortion under all conditions of operation of the embroidery machine, and means to hold the rails in the same plane when in engagement with the fabric.

4. In a device for preventing the distortion of the stretched fabric of embroidery machines, a pair of light rails hinged together at their proximate edges, pins in their opposite edges spaced apart in accordance with the repeat design, and means for latching the rails together in engagement with the fabric.

5. In a device for preventing the distor tion of the stretched fabric of embroidery as our invention, we have signed our names in presence of two subscribing witnesses.
