Sept. 13, 1938. G. s. TOMPKINS 2,130,253 r SWIFT GUARD- Filed May 29, 1957 L INVENTOR IGERALD SAMUEL TOMPKINS BY HIS ATTORNEYS Patented Sept. 13, 1938 UNITED STATES PATENT QFFiQE.
SWIFT GUARD Application May 29, 1937, Serial No. 145,625
6 Claims.
This invention relates to swift guards, and has for its main object to prevent strands of yarn of a skein from catching on the points of the swift spokes.
Another object, in mounting skeins on swifts preliminary to winding, is to prevent damage of the skein due to careless handling such as when an operator impales a skein over the spoke ends or points.
A further object, in the winding operation, is to prevent the slack strands of yarn at the surface of a loopy skein, from falling over the points of the swift spokes and causing tangles and yarn breakage. With the present invention any such strands cannot wrap around the spokes, but are cammed past and over the ends of the spokes, without hanging up or stopping the rotary motion of the swift.
In the drawing- Figure 1 is a plan of a swift having a guard according to the present invention; and
Figure 2 is an end elevation of the same showing in full lines the skein mounted thereon, and in dotted lines the skein partially mounted.
The form of swift shown comprises a hub 3 and divergent spokes 4 radiating therefrom. There are two sets of spokes one at each end of the hub which is accordingly of hour glass shape, preferably of wood and having enlarged ends 5 and 6 to receive the respective sets of spokes. Metal spindles i and. B extend axially therefrom, to journal the same for rotation.
Opposite pairs of spokes carry yarn supports ID. These yarn supports are preferably loops of cord 35 slipped over the ends of the pairs of spokes and adjustably held in position by their own tension or slight inward cantilever bending of the spokes, or both.
The guard according to the preferred embodi- 40 ment of the present invention shown by way of illustrative example, engages the outer ends of adjacent divergent spokes and extends inward therebetween, thus forming a star shaped guard. In the form shown a pair of separate wire guards each have a number of outer points l2 equal to the number of spokes of the skein swift upon which these guards are mounted. Each point of the guards is suitably fastened in a shallow groove H3 in the outer end of each spoke, from which 50 point the wire curves as at M, inward toward the swift hub, meeting at a point l5, thus forming reentrant portions [6. The wire is preferably a single piece, having its ends soldered or brazed as shown at I? but a larger number of joints in other 55 positions may be provided if desired.
In order to prevent the loose portion of the skein from becoming entangled under the inner points l5 of the guard, these points l5 are joined by members l8 such as rubber bands passed over the spokes 4 and the outer wire guard points l2 associated therewith. Of course a single longer rubber band could be passed around inside alternate spokes, or both forms could be made of wire.
It should be noted that the re-entrant portions 5 or angles 16 of the guard greatly facilitate the mounting of the skein on the yarn supports. The skein 20 partly mounted as shown in dotted lines in Figure 2, being on the outside of one of the spokes as shown at 4b for example, may pass 10 through the two adjacent re-entrant portions it.
v This provides slack to facilitate passing the skein over the outer end of the next spoke 4c. The yarn support if carried by that spoke need be moved toward the hub only a slight distance to provide 15 the slack necessary to pass the skein over the end of the last spoke db. After the skein has been passed over all of the spokes of one side, onto the yarn supports Hi, the yarn supports are adjusted by pushing them outward, to center the skein and 20 also maintain it taut.
I claim:-
1. A swift comprising a hub and divergent spokes, yarn supports carried by said spokes, and a guard engaging the outer ends of adjacent divergent spokes and extending inward therebetween.
2. A swift comprising a hub and spaced sets of divergent spokes, yarn supports extending between opposite pairs of said spokes, and a guard for each set engaging the outer ends of adjacent divergent spokes and extending inward therebetween.
3. A swift comprising a hub and divergent spokes, yarn supports carried by said spokes, and a star shaped guard, the outer parts of said star shape engaging the outer ends of adjacent divergent spokes.
4. A swift comprising a hub and divergent spokes, yarn supports carried by said spokes, and a wire loop guard secured in notches outwardly facing in the ends of adjacent divergent spokes said guard extending inwardly between the adjacent spokes.
5. A swift comprising a hub and spaced sets of divergent spokes, yarn supports extending between opposite pairs of spokes, and a guard for each set comprising a star shaped wire loop guard, the outer parts of said star shape being secured in notches in the ends of the spokes of the swift.
6. A swift comprising a hub and spaced sets of divergent spokes, yarn supports extending between opposite pairs of said spokes, a guard for each set engaging the outer ends of adjacent divergent spokes and extending inward therebetween, and means connecting the adjacent inwardly extending portions.
