No. 498,809 Claims priority, application Switzerland, Nov. 3, 1964, 14,174/64 2 Claims. (Cl. 112-83) This invention concerns a device for the attendance of the embroidery operation of an embroidery machine, the device permitting easy access to the fabric frames on the machines.
An arrangement of running boards is commonly used for the attendance of embroidery machines. These running board attendance devices have the disadvantages of hindering access for the attendance to the operations on the lower fabric frame of the embroidery machine. The application of hinged running boards has been suggested, e.g running boards which can be opened, to alleviate this condition of no access, but these hinged running boards are not completely satisfactory, especially for machines designed for a large stitching height and known as the high model embroidery machine.
The purpose of this invention is to provide an attendance device which will permit unimpeded attendance both on the lower and upper fabric frame of an embroidery machine incorporating these frames, and to provide easy and convenient accessibility and safety in the attendance of the embroidery machine.
This purpose is achieved by providing a novel ladder structure serving as a station which can be displaced along the embroidery machine and which is supported by two guides, at least one of these guides being fastened to the machine frame. Preferably the top guide extends over the entire length of the machine, but both guides may so extend. The ladder is swivel-mounted to assume various operative positions and is provided with a clamp device which intermeshes with a driven pulling mechanism attached to the embroidery machine in order to move the ladder positively, by the choice and under the control of the operator. The ladder is provided with a brake or an arresting device to make it more useful.
The object of the invention is illustrated by way of eX- ample in the accompanying drawing in which:
FIGURE 1 shows the arrangement of a ladder on the left side of an embroidery machine;
FIGURE 2 illustrates a cross section of line II of FIGURE 1;
FIGURE 3 is a partial cross section of the embroidery machine with a somewhat different construction of the ladder as compared to FIGURE 1;
FIGURE 4 shows the front side of a ladder with additional parts; and
FIGURE 5 is a side View of FIGURE 4.
The side pedestal 1 and the beam pedestal 2 are connected with the top and bottom beams 3 and 4 (FIG. 1). Between the two top and bottom beams 3 and 4, the fabric frame is hung up in the commonly known manner, but this is not further illustrated. The fabric frame 5 supports the fabric rollers 6 which take up the embroidered fabric 7 The top guide rail 8 and the bottom guide rail 9 (FIG. 2) are supported by extensions 10 and 11 which are attached to the beams 3 and 4. The construction as per FIG. 3 provides [for a direct attachment of the bottom guide rail 12 to the lower part of the beam pedestal 2.
The spools 13 and the thread rollers 14, as well as the thread guide rods 15 and the needles 16 with supports 17, are illustrated on the right side of FIG. 2. The endless traction cable 19, which is guided over the rollers 18 (FIG. 1), is continuously driven and extends over the length of the embroidery machine.
A ladder 20 is provided on each side, front and back, of the embroidery machine, and this ladder is fashioned as illustrated in the side View in FIGS. 2 and 5, or FIG. 3. In the construction illustrated in FIGS. 2 and 5, the bars 33 run at acute angles to each other, whereas FIG. 3 shows them arranged parallel to each other. Approximately from the middle of the ladder 20 upwards, the side hand grip rods 21 are arranged on the bars 33. The lower half of the bars 33 contain the footboa-rds 22. The support 31 (FIG. 2), which extends from the rear of a footboard to the rear bars 33, is provided to hold a spool or shuttle container 32. The upper and lower parts of the ladder 20 bear against the rollers 23 and 24, the top rollers 23 being of convex shape on the running surface to fit the guide rail 8. The rollers 24 are supported above the floor.
In FIG. 2, an arrow indicates how the ladder is swivelled and in this position is moved across the beam pedestals 2 to the next machine section. The modification as per FIG. 3 does not require the ladder to be swivelled. It can be moved freely along the entire length of the embroidery machine.
According to FIGS, 4 and 5, the ladder 20 is provided with a clamp device 26, 27 which engages the traction cable 19 by transmission from the twin lever 25 over the rod 29 both being mounted on the ladder. For its operation, the twin lever 25 is provided with two pedals 28. In the illustrated position of the lever 25, the top' clamp 26 is disengaged and the bottom clamp 27 is operational, effecting a displacement of the ladder 21 to the left when the traction cable 19 is in motion. By depressing the right pedal 28 in FIG. 4, the bottom clamp 27 is disengaged via the rod 29 and the top clamp becomes operational. Setting the lever 25 in its middle position permits the cable 19 to slide in the clamps 26, 27. Consequently, the ladder can be moved by hand. The ladder 20 can also be held in any desired position by means of the brake device coacting on the upper guide rail.
I claim:
1. An attendance device of a shuttle embroidery machine having a machine frame, upper frames for holding the fabric and lower frames for holding the fabric, said frames extending along the length of said machine, said device comprising: a swivelly mounted ladder serving as a station, said ladder being movable along the length of the embroidery machine; two guides forming a guide assembly, one above the other, corresponding to said upper and lower fabric frames; means fastening at least one of said guides to said machine frame to anchor the guide assembly to said machine; means on said ladder riding upon and supporting said ladder on said guides; driving means for moving said ladder along said guides; a pulling mechanism comprising an endless cable supported on and extending the length of the machine frame and driven by said driving means; and clamping means mounted on said ladder in position to engage said cable, the movement of said clamping means being under the control of the operator.
2. A device as claimed in claim 1, wherein said ladder has a brake device which engages one of said guides to lock said ladder.
