LINE SPOOL ASSEMBLY

Abstract: In a line spool assembly of the type wherein a spool member (1) is provided with an end flange (3) and an axially arranged outlet member (5), the provision of an arm (7) which is mounted freely rotatable about the spool axis and extends beyond the edge of the spool flange (3) and there carries a guide member (8) adapted to carry a line (4) from the spool (1) towards the outlet member (5) for the purpose of facilitating the winding off the line.

Description: Line spool assembly. The present invention relates to a line spool assembly comprising a spool member which is provided with an end flange, and the purpose of the invention is to facilitate the winding off of a line. In hitherto common constructions of line spools with end flanges, the line, when being hauled off from the spool is highly apt to be caught by the edge of the end flange, so that the winding off is hampered or even prevented. According to the invention this known inconvenience is avoided thereby that an arm is mounted freely rotatable about the spool axis, the free end of the arm extending beyond the end flange and carrying a guide member adapted to carry a line from the spool to an outlet member situated in the spool axis. In such an assembly a line will, during off-winding run freely from any point along the length of the spool to the outlet without being subject to great frictional or bending resistance and without any danger of jamming at the end flange of the spoolv The guide member at the end of the rotatable arm may be in the form of a solid piece of any material provided with a curved bore for the guiding of the line, but it is particularly suitable to make the piece in the form of a sleeve having its axis extending parallel to the spool axis and having a convex inner boundary surface, so that the line running from any point along the length of the spool will always enter tangen¬ tially to the inner boundary surface. The accompanying drawings illustrate an example of how the assembly of the invention may be brought into practice. Figure 1 is a side view of a spool assembly according to the invention. Figure 2 is an end view corresponding to that of Figure 1. Figure 3 is a side view in a larger scale and partly in section corresponding to that of Figure 1. In the drawings, 1 is a spool which is mounted on a support 2 and is provided with an end flange of a cover 1. A line which is wound on the spool is shown at 4 and is shown under off-winding with guidance of the line through an outlet 5. In the axis of the spool 1 and the flange 3 a radial arm 7 is mounted freely rotatable and extending beyond the edge of the flange 3 and there provided with a guide member 8 which carries the line 4 freely about the edge of the flange 3. In the embodiment which is shown in the drawings, the guide member 8 is in the form of a sleeve having a convex inner boundary surface, but obviously the member 8 may be otherwise formed, the essential being that the line 4 may run with the less possible resistance from the spool ' 2 forwardly to the outlet 5. During off-winding of the line 4, i.e. with pull in the line during the run through the outlet 5, each pull will cause the guide member 8 at the free end of the arm 7 to rotate around the spool as indicated by means of an arrow in Fig. 2 and is hereby maintaining the line clear of the edge of the flange 3, so that the flange cannot cause any obstruction to the free run of the line from any point along the height of the spool to the outlet 5. In the above description relatively to the drawing it is presumed that the spool 2 is stationary during the off-winding. If, on the other hand, it is freely rotating during off- winding, the arm 7 with the guide member 8 will follow the rotation of the spool 2 with the flange 3 and in this case also, perform its function.

Claims: Claims. 1. A line spool assembly comprising a spool member which is provided with an end flange, c h a r a c t e r i s e d i n an arm (7) which is mounted freely rotatable about the axis of the spool and extends beyond the edge of the end flange (3) and there carries a guide member (8) which is adapted to carry a line (4) from the spool (1) to an outlet member (5) situated in the spool axis. 2. A device as claimed in claim 1, c h a r a c t e r i s e d therein that the line guide member (8) is in the form of' a sleeve having its axis parallel to the spool axis (6) and a convex inner boundary surface.
