J. NOGUERA BOBBIN HOLDER Oct. 1, 1946.

" Claims. (c1. sea-1st) This invention relates to mechanism for suspending bobbins in the creels of spinning or preparing machines.
Mechanism for this purpose is described in U. S. Patent No. 2,095,518 (F. Casablancas) which comprises a cylindrical casing which is adapted to rotate freely on a fixed part of a'frame and inside which there is provided a catch formed by a rotatable member of elongated form which may take up two positions, one horizontal, in which it projects through apertures in the wall of the casing, thus forming projections for retaining the bobbin, and the other vertical, in which it does not project from the tube and permits of withdrawing or fitting the bobbin. The mechanism according to the present invention is of this general type but possesses several advantages over the existing constructions as hereinafter explained.
According to the presentinvention, mechanism of the type described comprises a resilient member of elongated U-shape mounted within the cylindrical casing with th arms of said member extending downwardly and embracing between them the rotatable catch, the end of one am being formed as a hook which is adapted, on
. upward movement of said member with respect to the rotatable catch, to engage said catch and to rotate the catch into the vertical or horizontal position. r
According to the preferred embodiment, the rotatable catch comprises a pair of aligned elongated hexagonal plates spaced apart by two parallel plates disposed one on each side of the pivot of the catch, the aforesaid hook engaging one or other of said parallel plates to cause rotation of the catch. According to a further feature of the invention, the necessary movement of the resilient member within the cylindrical casing is effected by means of a collar which encircles the cylindrical casing and is provided with means adapted to engage the loop of the U-shaped resilient memher through vertical slots in the cylindrical casing. whereby upward movement of said collar causes upward movement of the resilient member and rotation of the catch. Said engaging means may also support a dished member for locating a coil spring bearing between said dished member and the upper end of the cylindrical casing and against the action of which the collar is raised. The bottom surface of the collar may be bevelled whereby, in the horizontal position of thecatch,
tbe'bobbin is held between said bevelled suriace v v a"? and the upper inclined edges, of the hexagonal catch.
The invention will now be described by way of example with reference to the accompanying drawing,inwhich:
Figure 1 is a'vertical section through a bobbin-- suspension. mechanism according to the invention;
Figure 2 is a partialsection on the line 11-11 of Figure-1, and
Figure 3 is an elevation'showing a bobbin in position on the bobbin-suspension mechanism.-
The mechanism comprises a die cast tube Ill having a die cast cover 4 I secured to its upper end, by being screwed to a flange its on the tube. A plate I2 is tightly held between the top face of the tube In and an abutment ii on said cover It and the whole is rotatably mounted on a screw It by means of balls It and inner ring it. An
outer casing I1 is also supported by the. screw is. In the lower part of the tube It is a catch it. comprising a pair of aligned elongated hexagonal plates is spaced apart by two parallel plates 30 mounted on a pin 2 I. which is rotatably supported by'the tube ill. Vertical slots 22 are formed in the wall of the tube In to allow the ends of the plates It to protrude beyond the tube ill in one position of the catch. A resilient member 23 of elongated U-shape is supported. at its upper looped end 24 by means of a key which extends stitute a locating member for a coil spring 29 which bears between said dished member 28 and the plate It; It will be seen that upward move ment of the thimble 21 against the action of the spring 29 causes upward movement of the resilient member by reason of the engagement of the key 25 with the looped end 24 of the resilient member 23. ,The arms 30 of the resilient member 23 extend downwardly and embrace between them the rotatable catch it. The end of one of said arms is bent back upon itself to form a hook 3| which is adapted, on upward movement of the resilient member as aforesaid. to engage one or other of the plates 20 to cause rotation of the catch.
The bottom surface of the thimble 21 is bevelled as at 32 whereby, in the horizontal position of the catch l8 as shown in Figure 1, the bobbin 33 is held between said bevelled surface 32 and the upper inclined edges 36 of the plates H (see Fig- Such a construction presents several advantages over the existing art.
Thus, owing to the pressure of both arms 30 of the resilient member 23 towards the centre of the catch IS, the catch is completely moved into its new position by the upward movement of the resilient member, making the attachment and removal of the bobbin easier and quicker. In the construction of the existing art, the catch is not brought into a definite vertical or horizontal position until the pawl has descended and pushed against-it again.
Furthermore, once the hook 3| has been brought into engagement with one of the plates 20, it is retained in engagement therewith by the resilience of the U-shaped member 23, whereas in the construction according to the existing art,
, the pawl is urged towards the centre of the catch only by the remotely-placed top spring. As in the present construction the top spring 29 is not required to swing the hook inwards, it is possi- Ible to use a lighter spring whereby the operation of the bobbin holder is correspondingly lighter.
Finally, owing to the freedom of movement of the U-shaped member 23 in the downward direction, due to the fact that the hook only becomes operative during the upward movement of said member, it is possible for the operating collar 21 to descend until it bears on the bobbin with the result that the lbobbin is ripped between the collar and the catch and is therefore eiiectively centred with respect to the :body of the bobbin holder.
What I claim and desire to secure Patent 01 the United States is: i
a 1. Mechanism of the kind described for suspending bobbins in the creels of spinning or preparing machines, comprising a tubular. casing, a catch pivotally mounted in said tubular casing so constructed as to be rotated into either a horizontal or vertical position, a resilient member by Letters of elongated U-shape mounted within said tubular casing having arms depending downwardly and embracing between them the catch, a hook carried by one of the arms of said resilient member adapted on upward movement of said member to engage and rotate said catch into either the horizontal or vertical position.
2. Mechanism accordin to claim 1, wherein the rotatable catch comprises a pair of aligned elongated hexagonal plates spaced apart by two parallel plates disposed one on each side of the pivot of the catch, the aforesaid hook engaging one or other of said parallel plates to cause rotation of the catch.
3. Mechanism according to claim 1, wherein movement of theresilient member within the tubular casing is eifected by means of a collar which encircles the tubular casing and is provided with means adapted to engage the loop of the U-shaped resilient member through vertical slots in the tubular casing.
4. Mechanism according to claim 1 characterized by the fact that the movement 01' the resilient member within the tubular casing is effected by means of a collar which encircles the tubular casing and is provided with means adapted to engage the loop of the U-shaped resilient member through vertical slots in the tubular casing and the engaging means support a dished member for locating a coil spring bearing between said dished member and the upper end of the tubular casing and against the action of which the collar is raised. g
5. Mechanism according to claim 1 characterized by the fact that the movement of the resilient member within the tubular casing is eii'ected :by means of a collar which encircles the tubular zontal catch.
