Abstract
A spool assembly for pintle or other kind of cables, which is simple and efficient in use and is advantageously made of a very small number of standardized elements that can be assembled in a plurality of ways to meet any specific requirements, such as, for example, the need for a handle, the need for having a pair of spools immediately available to the user, or the need for a stopper to rigidly hold the external end of the pintle. The assembly has one or two cylindrical spool in which pintles may be wound. It also has one or two cylindrical spool receiving members having a cylindrical peripheral wall, a flange preferably in the form of a ring projecting radially inwardly from one of the edges of the peripheral wall to hold the spool, a plurality of hooks integral to and projecting from the other edge of the peripheral wall at given intervals, and an opening provided in the peripheral wall to allow the cable wound in the groove of the spool to be pulled out. The assembly further has a flat, preferably ring-shaped circular cover having an external diameter that can be engaged by the hooks and held tight by these hooks against the other edge of the spool receiving member, to form therewith a casing in which each spool is freely mounted.
Description
SPOOL ASSEMBLY FOR PINTLE
Background of the invention a) field of the invention The present invention relates to a spool assembly for use in storing and handling a cable-like member which is preferably but not necessarily a pintle.
b) brief description of the i riot art In the paper making industry, it is of common practice to use fabric l0 belts that are made of sections connected to each other to form an endless loop.
Such belts carry the wet fibrous sheets that are prepared from the processed pulp.
It is also of common practice to connect the adjacent ends of the belt sections by means of seams made by passing a cable known in the trade as a "pintle"
through a tubular passage formed by intermeshed loops of fabric yarns projecting at the ends of the adjacent sections when the same are intefitted and held together.
Usually, the pintle consists of a mono- or multi-filament yarn whose leading end is attached to a stiff guiding wire made of metal, which acts as a needle to facilitate insertion of the yarn into the passage formed by the loops.
Further details regarding the use of pintles to connect fabric belt 2 o sections, can be found to the preambles of U.S. patent Nos. 4,842,212 to ASTEN
GROUP, INC. and 5,033,618 to ALBANY INTERNATIONAL CORP.
Of course, it is necessary that the pintle be stored and made available in such a manner as to make its use and installation as fast and easy as possible, especially in the case of replacement of used or damaged sections of the endless belt of a paper making machine) which must be made in a very fast manner on the premises.

BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is an exploded perspective view of a spool assembly according to the invention, including two independent spools mounted in parallel relationship;
Fig. 2 is a cross-sectional view of one side of the spool assembly showing Fig. 1 in semi-assembled form.
Fig. 3 is a perspective view of a portion of a spool receiving member for use in a spool assembly according to the invention) the member including a locking tab to hold the cable projecting out of the spool.
DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
The spool assembly 1 according to the invention as shown in the accompanying drawings is intended to be used for storing and handling at least one and preferably two cable-like members 3, 3' which preferably but not necessarily consist of pintles made of one or more yarns 5,5' connected to a stiff guiding pin 7, 2 0 7'.
The spool assembly 1 comprises eight basic elements preferably made of molded plastic material, namely:
- a pair of identical spools 11, 11';
- a pair of identical spool receiving members 21, 21';
- a flat cover 41:
- a handle 51; and - a pair of identical stoppers 61,61'.
Each spool 11,11' is formed with a radially outwardly opening groove 12 in which the corresponding pintle 3 may be wound. The spool 11 which has a 3 o given outer diameter and a given thickness "T", preferably comprises a central hub 13 in which is made a spindle-receiving hole 14, a peripheral ring 15 having a square, U-shaped cross-section that opens radially outwardly and defines the above ~:
,, S.w...
2~~38~~
mentioned groove 12, and a plurality of radial arms 16 joining the central hub 13 to the peripheral ring 15.
Each spool receiving member 21,21' has a central axis which, when the spool assembly is in assembled form, is coaxial with the spindle receiving hole 5 14 of the corresponding spool 11,11', and comprises a cylindrical peripheral wall 22 having a pair of opposite edges 23,24 that are round in shape. The peripheral wall 22 also has an outer diameter, an inner diameter that is substantially equal to or slightly larger than the outer diameter of the corresponding spool, and a height "H"
that is substantially equal to or slightly larger than the thickness "T' of the spool.
Each spool receiving member 21,21' also comprises a flange 25 projecting radially inwardly from one of the round edges, say 23, of the peripheral wall 22 to hold the corresponding spool 11,11' when this spool is coaxially inserted therein through the opening defined by the other one of the round edges. Preferably, as is shown, the flange 25 of the spool receiving member is in the form of a flat ring that extends in a plane perpendicular to the central axis of the member. Such a flat ring has an inner edge 26.
Each spool receiving member 21,21' further comprises hooking means integral to and projecting from the edge 24 of the peripheral wall 22 at given intervals along this edge and in a direction parallel to the direction of the central axis of the 2 o spool receiving member. These hooking means preferably consist of a plurality of small, slightly resilient hooks 27 that are circumferentially distributed along the edge 24 of the peripheral wall 22 of the spool receiving member, each hook 27 being sized and positioned to engage a hook-receiving slot 43 provided for this purpose in the cover 41 as will be explained hereinafter.
An opening 28 is provided in the peripheral wall 22 to allow the cable 3,3' wound in the groove 12 of the corresponding spool to be pulled out, when the spool is inserted into the member. As is clearly shown in Fig. 1, the opening extends centrally between the edges 23,24 of the peripheral wall 22 of the spool receiving member and is elongated in a direction perpendicular to the central axis 3 0 of this member. The opening 28 also has a pair of opposite ends 29,30 that taper radially inwardly toward each other.
The flat cover 41 is circular in shape and has an external diameter 2~g3884~
sufficient to make it engageable by the hooks 27 and held tight by these hooks against the edge 24 of the spool receiving member to form therewith a pair of parallel casings in which the spools 11,11' are freely mounted. As is shown, cover 41 is preferably in the form of a flat ring which extends in plane perpendicular to the central axis of each of the spool receiving members when said members are hooked to it. This feature combined with the ring shape of the flange 25 of each member makes it possible for the spindle-receiving hole 14 of the spools 11,11 ' to remain accessible and usable even when the spools are mounted in the casings formed by their corresponding spool receiving members 21,21' and their common cover 41.
1 o Preferably, the cover 41 has an external diameter that is larger than the outer diameter of the peripheral wall 22 of each of the spool receiving members 21,21'. As a result, a peripheral portion 42 of the cover projects radially outwardly from the spool receiving members 21,21' when these members are hooked to the cover 41.
The hook receiving holes 43 mentioned hereinabove are made in this peripheral portion 42 at such locations as to be engageable by the hooks 27 projecting from each of the spool receiving member 21,21'. Other hook-receiving holes 44 may be provided in the peripheral portion 42 of the cover to receive hooks 52 projecting from both ends of the handle 51, when such a handle is wanted.
2 0 Like the handle 51, the stopper 61,61' are not compulsory and can be used only if desired. Each stopper 61,61' is devised to be snapped onto one of the casings formed by the spool receiving members 21,21' and the cover 41 to rigidly hold any portion of the cable projecting outwardly from this casing through the corresponding opening 28. As is shown, each stopper is L-shaped and sized to fit onto the peripheral wall 22 and the flange 25 of one of the spool receiving members.
For this purpose, each stopper has a hook 62 at one end that is sized and positioned to engage the inner edge 26 of the flange 25 and another hook 63 at another end that is sized and positioned to engage the outer edge of the cover 41.
Notches 31 may be provided along the inner edge 26 of the flange 25 to prevent the 3 o stopper from inadvertently rotating about the corresponding casing. A
padding 64 may be provided on the arm of the stopper that is adjacent the peripheral wall 22 in use, to give room and retain the cable 3.
a ~Q8388~
As can be understood, when only one cable-like member 3 is wanted, the spool assembly can be made of one of the spools, say 11; one of the spool receiving members, say 21, and the cover 41 exclusively, with or without the handle 51 and/or one of the stopper.
Instead of incorporating one or two stopper 61, 61' as disclosed hereinabove, the spool assembly 1 according to the invention may include spool receiving members 21, 21' on which a locking tab 71 is integrally molded, as is shown in Fig. 3. The tab 71 extends outwardly of and parallel to the peripheral wall 22 of the receiving member at a short distance from the opening 28 and is 1 o positioned and shaped in such a manner as to receive and rigidly hold by pinching the cable 3 that projects out of the opening 28.
1 o Preferably, the cover 41 has an external diameter that is larger than the outer diameter of the peripheral wall 22 of each of the spool receiving members 21,21'. As a result, a peripheral portion 42 of the cover projects radially outwardly from the spool receiving members 21,21' when these members are hooked to the cover 41.
The hook receiving holes 43 mentioned hereinabove are made in this peripheral portion 42 at such locations as to be engageable by the hooks 27 projecting from each of the spool receiving member 21,21'. Other hook-receiving holes 44 may be provided in the peripheral portion 42 of the cover to receive hooks 52 projecting from both ends of the handle 51, when such a handle is wanted.
2 0 Like the handle 51, the stopper 61,61' are not compulsory and can be used only if desired. Each stopper 61,61' is devised to be snapped onto one of the casings formed by the spool receiving members 21,21' and the cover 41 to rigidly hold any portion of the cable projecting outwardly from this casing through the corresponding opening 28. As is shown, each stopper is L-shaped and sized to fit onto the peripheral wall 22 and the flange 25 of one of the spool receiving members.
For this purpose, each stopper has a hook 62 at one end that is sized and positioned to engage the inner edge 26 of the flange 25 and another hook 63 at another end that is sized and positioned to engage the outer edge of the cover 41.
Notches 31 may be provided along the inner edge 26 of the flange 25 to prevent the 3 o stopper from inadvertently rotating about the corresponding casing. A
padding 64 may be provided on the arm of the stopper that is adjacent the peripheral wall 22 in use, to give room and retain the cable 3.
a ~Q8388~
As can be understood, when only one cable-like member 3 is wanted, the spool assembly can be made of one of the spools, say 11; one of the spool receiving members, say 21, and the cover 41 exclusively, with or without the handle 51 and/or one of the stopper.
Instead of incorporating one or two stopper 61, 61' as disclosed hereinabove, the spool assembly 1 according to the invention may include spool receiving members 21, 21' on which a locking tab 71 is integrally molded, as is shown in Fig. 3. The tab 71 extends outwardly of and parallel to the peripheral wall 22 of the receiving member at a short distance from the opening 28 and is 1 o positioned and shaped in such a manner as to receive and rigidly hold by pinching the cable 3 that projects out of the opening 28.
