(9) The housing 12 comprises a lower housing body 36 and a housing cover 38 which is bolted, glued, and/or otherwise secured on top of the body 36. Although other shapes can be used, the outer perimeter 18 of the housing body 36 is preferably circular to facilitate holding the stuffing device 2 in one hand. At least most of the outer perimeter of the housing cover 38 also has a corresponding circular shape, except for the attachment ear 32 which preferably projects from the perimeter of the housing cover 38. It will be understood, however, that the attachment ear 32 can alternatively project from the perimeter 18 of the housing body 36 or from both the housing cover 38 and the housing body 36.

(10) The open side slot 20 of the housing 12 extends laterally from an outer perimeter opening 40 of the open slot 20 to an inner end portion 42 of the open slot 20. The inner end portion 42 of the open side slot 20 is preferably located in the central portion or area of the housing 12. The open side slot 20 also has (i) an open top 44 at the top 14 of the housing 12 (i.e., through the housing cover 38) and (ii) an open bottom 46 at the bottom of the housing 12 (i.e., through the bottom of the lower housing body 36). The open top 44 and the open bottom 46 extend along the length of the open side slot 20.

(11) The housing 12 also includes (a) an open drive wheel slot 48 in which the drive wheel 24 is rotatably positioned and (b) an open idler wheel slot 50, opposite the drive wheel slot 48, in which the idler wheel 26 is rotatably positioned. The drive wheel 24 and the idler wheel 26 are preferably perpendicular to the open slot 20. The open drive wheel slot 48 extends from, and is preferably perpendicular to, the open side slot 20 and includes: an open inner end 52 which is in communication with the inner end portion 42 of the open side slot 20: an open top 54; an open bottom 56; and a closed outer end 58. The open idler wheel slot 50 also extends from and is preferably perpendicular to the open side slot 20 and includes: an open inner end 60, opposite the open inner end 52 of the drive wheel slot 48, which is in communication with the inner end portion 42 of the open side slot 20; an open top 62; an open bottom 64; and a closed outer end 66.

(12) The drive wheel 24 is secured or formed in fixed position on the turning member 30 so that the drive wheel 24 must rotate with the turning member 30. The turning member 30 includes (a) a first segment 68 which extends through a perimeter opening 70 of the housing 12 to a first side 72 of the drive wheel 24 and (b) a distal segment 74 which extends from the opposite side 76 of the drive wheel 24. The first segment 68 of the turning member 30 rotatably extends through one or more bushings and/or bearings 78 which are held in a cavity 80 forned in the lower housing body 36 adjacent the drive wheel slot 48 on the first side 72 of the drive wheel 24. The distal segment 74 of the turning member 30 rotatably extends through one or more bushings and/or bearings 82 held in a cavity 84 formed in the lower housing body 36 adjacent the drive wheel slot 48 on the opposite side 76 of the drive wheel 24.

(13) In the embodiment 2 of the inventive stuffing device shown in FIGS. 1-3, the turning member 30 of the device 2 is a hand crank for rotating the drive wheel 24 by hand.

(14) The idler wheel 26 is rotatably held on an idler shaft 86 which extends through the idler wheel 26. A first end segment 88 of the idler shaft 86 extends into a cavity 90 formed in the lower housing body 36 adjacent the idler wheel slot 50 on a first side 92 of the idler wheel 26. An opposite end segment 94 of the idler shaft 86 extends into a cavity 94 formed in the lower housing body 36 adjacent the idler wheel slot 50 on the opposite side 96 of the idler wheel 26.

(15) The idler shaft 86 is retained in the lower housing body 36 by a pair of pins 98 and 100 which extend, respectively, into the idler shaft cavities 90 and 94 of the lower body 36 and through the end segments 88 and 94 of the idler shaft 86. The pins 98 and 100 prevent the idler shaft 86 from rotating and are perpendicular to the idler shaft 86 so that the idler shaft 86 can slide on the pins 98 and 100 and carry the idler wheel 26 toward and away from the drive wheel 24. The one or more biasing elements 28 used in the inventive stuffing device 2 continuously urge the idler shaft 86 and the idler wheel 26 toward the drive wheel 24.

(16) In the embodiment 2 of the inventive device shown in FIG. 2, the biasing elements 28 are coil springs which are positioned in the idler shaft cavities 90 and 94 around the pins 98 and 100. However, it will be understood that other common types of springs, or other biasing elements, can alternatively be used.

(17) The drive wheel 24 has a contacting surface 102 which surrounds the drive wheel 24 and extends toward or into the inner end portion 42 of the open side slot 20 of the housing 12. The idler wheel 26 has a contacting surface 104 which surrounds the idler wheel 26 and extends toward or into the inner portion 42 of the open side slot 20, opposite the contacting surface 102 of the drive wheel 24, such that a gap 106 for receiving the rope or other cord 22 of the bag 4 or 10 is formed in the inner end portion 42 of the open side slot 20 between the contacting surface 102 of the drive wheel 24 and the contacting surface 104 of the idler wheel 26. The biasing elements 28 acting on the idler wheel 26 operate to continuously press the rope or other cord 22, regardless of size, into gripping contact with drive wheel 24 while also allowing the gap 106 between the drive wheel 24 and the idler wheel 26 to expand as needed to receive a cord 22 of larger diameter.

(18) The contacting surface 102 of the drive wheel 24 can be formed of any material which is effective for gripping the rope or other cord 22 and pulling the cord 22 throu.sup.gh the inventive stuffing device 2. Examples of such materials include, but are not limited to, polyurethane rubber and polyurethane silicone. To further assist in gripping, and to operate as a guide for retaining the cord 22 in place between the drive wheel 24 and the idler wheel 26, the contacting surface 104 of the idler wheel 26 is preferably concave (inwardly curved).

(19) An alternative embodiment 110 of the inventive stuffing device is depicted in FIGS. 4 and 5. The alternative embodiment 110 is the same as the embodiment 2 shown in FIGS. 1-3 except that the turning member 112 of the inventive device 110 is a drive shaft which is preferably rotated by a power tool. By way of example, the drive shaft 112 is shown as having a hex head 114 on the projecting outer end thereof for turning the drive shaft 112 using an impact driver, a power drill, a pneumatic wrench, or other power tool.

(20) The inventive stuffing device 110 is well suited for production in larger sizes, e.g., for use in a stand 8 of the type shown in FIG. 5 for hanging and stuffing a larger life safety bag or other large bag 10. However, the inventive stuffing device 110 can also be produced as a smaller hand-held device for, e.g., holding the device 110 in the open top 6 of a smaller throw bag 4.

(21) The apparatus 120 illustrated in FIG. 5 which uses the stand 8 for stuffing a larger bag 10 comprises: a horizontal frame or platform 122 of the stand 8 which is supported above the ground or floor 124 by a plurality of upwardly extending legs 126: a plurality of bag hooks or other bag attachments 128 which extended downwardly from or are provided on the bottom of the horizontal frame or platform 122; a holder 130 on the bottom, on the top, or in the horizontal frame or platform 122 which holds the inventive stuffing device 110 or 2 above or inside the open top 132 of the bag 10; a pulley or other guide 134 for the rope or other cord 22; and an arm 136 which extends upwardly from the horizontal frame or platform 122 to support and position the guide 134 above the inventive stuffing device 110 or 2.

(22) In the method of the present invention for stuffing a rope or other cord 22 into a throw bag 4, a life safety bag 10, or other bag, the inventive stuffing device 2 or 110 is positioned in or above the top opening 6 or 132 of the bag 4 or 10. Before, during, or after this step, the cord 22 of the bag 4 or 10 is delivered into the open side slot 20 of the stuffing device 2 or 110 and is positioned in the gap 106 between the contacting surface 102 of the drive wheel 24 and the contacting surface 104 of the idler wheel 26. Subsequently, the crank handle 30, drive shaft 112, or other turning member of the stuffing device 2 or 110 is turned to rotate the drive wheel 24 to pull the cord 22 through the stuffing device 2 or 110 and thereby deliver the rope or other cord 22 into the bag 4 or 10.

(23) If the stuffing device 2 or 110 is a hand-held device, the stuffing device 2 or 110 will preferably be held in the top opening 6 or 132 of the bag 4 or 10 by hand. The hand-held device will preferably be a device 2 as illustrated in FIGS. 1-3 and the turning member of the device 2 will preferably be a crank handle 30 which is turned by hand.

(24) If a stand 8 is used to stuff the bag 10 as illustrated in FIG. 5, the step of the inventive method of positioning the stuffing device 2 or 110 in the top opening 132 of the bag 10 will preferably also include hanging the bag 10 from the horizontal frame or platform 122 of the stand 8. In addition, the stuffing device used in the stand 8 will preferably be the device 110 illustrated in FIGS. 4 and 5 and the turning member of the device 110 will preferably be a drive shaft 112 which is turned using a power tool.

(25) Thus, the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned above as well as those inherent therein. While presently preferred embodiments have been described for purposes of this disclosure, numerous changes and modifications will be apparent to those in the art. Such changes and modifications are encompassed within the invention as defined by the claims.
