NT FIQ EMBROIDERY-FRAME.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed February 12, 1913. Serial No. 748,010.

To all whom it may concern Be it known that I, MORRIS SoHonNrnLD, a citizen of the United States, residing in Rorschach, Canton of St. Gall, Switzerland, have invented new and useful Improvements in Embroidery-Frames, of which the following is a full, clear, and exact specification.

The object of the present invention is an embroidery frame which is distinguished from the embroidery frames hitherto in use, by the feature that it is composed of two distinct groups of frame members or rods, the frame members or rods of one group being placed upright so as to constitute the lateral parts of the frame and arranged so as to be only movable in a vertical direction relatively to stationary machine frame parts, While the frame members or rods of the other group carrying the fabric constitute the upper and lower parts of the frame and are guided by the members or rods of the first group so as to be movable relatively to them in a horizontal direction.

In the accompanying drawing, some constructional examples of the invention are illustrated as follows:

Figure 1 shows a partial front elevation, with certain parts in section, and Fig 2 a vertical section of a preferred construction in which the embroidery frame is supported adjustable transversely 'to its stitch motions, that is to say, transversely to the fabric plane ;v in Fig. 1, some parts have been omitted for the sake of clearness. Fig. 3 shows a modification in which the frame is rigidly mounted on the .machine frame. Figs. 4 and 5 show a guide for the frame rods of the one group. Fig. 6 shows in plan view a detail of the mechanism shown in Fig. 1.

Around fixed pivots 1 (Fig. 1) there move supporting bolts 4 which are connected one with another by compulsorily operated elements 2, 3. The embroidery frame is held in a position of equilibrium upon rollers 5 which are placed revolubly and adjustably in the axial direction upon the pivots 4 (Fig. 6), in consequence of the action of a counterweight 6, which, by means of a bar 7 and a lever 8, is guided to move parallel with itself. The rollers 5 are correspondingly supported in suitable tracks 9; these roller tracks 9 are provided with shoulders in front and behind (Fig. 2) in such a manner that they carry the rollers 5 with them along the pivots 4 when a pushing away of the frame from the fabric plane or an approach thereto is effected. These roller tracks 9 are each rigidly connected with a vertical frame rod 12 guided vertically in the guides 10 and 11, and on the other hand, they serve for the guidance of a lower horizontal frame rod 13 in the horizontal direction, and also an upper horizontal frame rod 14 is guided in sockets 15 of the vertical frame rods 12 in the horizontal direction. The

horizontal frame rods

13, 14 which form the one group of frame rods consequently participate in the vertical motions of the vertical frame rods 12 forming the other group, but they can also be moved relatively to these latter in the horizontal direction. The up-and-down motion of the embroidery frame, that is of the two groups of frame rods, is effected by means of the bolts 4, by the turning of the wheels 2,

while the horizontal relative displacement of the

frame rods

13, 14 is effected by the displacement of one of them and by a parallelogram lever connection 16, 17 18 which turns upon the stationary axles 19 and is made compulsory or positive for both horizontal frame rods in like manner. The vertical rods 20 which are rigidly connected with the

horizontal frame rods

13 and 14 are. for strengthenin purposes.

The

parts

21, 22, 23, 24 Fig. 2) are well known parts of the shuttle mechanism (shuttle tracks, shuttle driver bar, shuttle drivers, shuttle board). In the construction shown in Fig. 2 the guides 10, 11 of the frame rods 12 are attached to the shuttle boards 24. These latter are supported by the plungers 25, which are adjustable in bearings 26 on the machine frame 27, so that the entire embroidery frame is transported on the moving-out or forward or backward adjustment of the shuttle tracks upon the parts 25.

The

embroidery frame

12, 13, 14, 20 is provided as shown in Fig. 2 with

fabric rollers

28, 29, 30, 31 movably supported in the well known manner on the

frame parts

13, 14, 20, so as to allow of the displacement of the frame transversely to the fabric plane, but it might also be provided only with stretching devices for the fabric of the well known kind if the fabric rollers were placed outside the fabric frame.

According to Fig. 3 the vertical frame rods 12 are guided in fixed bearings 32 on the cross bars 27 in a vertical direction. Moreover, the vertical frame rods 12 are so bent over above and below, that a moving out of the shuttle mechanism is possible without a transverse movement of the fabric frame. The guiding of the vertical frame rods 12 is effected as shown in Figs. 4 and 5 by means of movable rollers 33 in such a manner that a displacement can only take place in the axial direction, while any turning motion of the frame rods 12 about themselves is prevented by means of a longitudinal rib 3% on the frame rods 12. The number of the driving points for the vertical and horizontal frame parts or rods is here of no importance.

Obviously the arrangement illustrated in the drawing according to which the weight of the frame rests upon the pivots 1 placed below the frame is only shown by way of example.

l/Vhat I claim is:

1. In an embroidering machine, a stationary machine frame, a fabric frame composed of two separate groups of frame rods, one of which has its frame rods distributed in upright position from distance to distance over the length of the frame so as to constitute side and intermediate frame parts and arranged so as to be only movable in a vertical direction relatively to the machine frame, while the frame rods of the other group carrying the fabric constitute the upper and lower longitudinal parts of the frame and are independently guided by and coupled to the frame rods of the first group so as to be movable relatively to them in one and the same horizontal direction.

2. In an embroidering machine, a stationary machine frame, a fabric frame composed of two distinct groups of frame rods, constituting the upper, lower and lateral parts of the frame, the frame rods of one group being placed upright so as to constitute the lateral parts of the frame and arranged so as to be only movable in a vertical direction relatively to the machine frame, while the frame rods of the other group constitute the upper and lower parts of the frame, extending over the whole length thereof, and are movably carried by the frame rods of the first group so as to be displaceable relatively to them in a horizontal direction, positive guide rollers being provided for the upright frame rods of the first group.

3. In an embroidering machine, a stationary machine frame, a fabric framecomposed of two distinct groups of frame rods constituting the upper, lower and lateral parts of the frame, the frame rods of one group being placed upright so as to constitute the lateral parts of the frame and arranged so as to be movable in a vertical direction relatively to the machine frame, while the frame rods of the other group constitute the upper and lower parts of the frame and are movably carried by the frame rods of the first group so as to be displaceable relatively to them in a horizontal direction, adjustable guide means being provided for the upright frame rods of the first group.

4:. In an embroidering machine, a machine frame carrying a shuttle board, a fabric frame comprising two distinct groups of members, the frame members of one group being placed upright and movable in the Goples of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
