Abstract
Abstract A bagging attachment intended for use with a shredding machine of the type which shreds garden waste and discharges it in an airborne stream spaced above but generally parallel to the ground. The attachment is in the form of an enclosure having spaced-apart front and back walls, side walls, and top and bottom walls. The front and back walls are self-supporting or hinged on the bottom wall. The front wall is of ''''picture frame'''' shape to register with the mouth of a refuse bag. The rear wall has an inlet opening which registers with the stream when the enclosure is supported upon the ground for direct discharge of the stream into the mouth of the bag. The side and top walls are formed by a single piece of porous fabric which serves to filter the escaping air, the edges being lapped over the supporting structure and held in place by a suitable fastening means, preferably of the hook-and-loop type. A slip joint is provided with the discharge chute so that the enclosure, with bag attached, may be readily slipped clear of the discharge chute, swung up to a bag-vertical position and shaken so that any collected dust or shredded material adhering to the porous fabric walls id dislodged into the mouth of the bag. In an alternate form of the invention, the structure includes a bottom wall panel having side flanges, a back wall panel having forwardly turned flanges and a front frame having rearwardly turned flanges, the adjacent portions of the flanges being secured by bolts or the like to form a rigid box structure, with flanges forming a continuous edge or supporting surface. The lateral edges of fabric forming a porous filter are secured along the supporting surface to complete the enclosure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
259 words
In a bagging attachment for use with a shredding machine having a discharge chute for discharging shredded garden waste in an airborne stream spaced parallel to the ground and for use with a plastic film refuse bag, the combination comprising an enclosure having front, back, top, bottom and side walls connected together about their edges, the front wall being of narrow picture-frame configuration defining a large central opening and having means for securing thereto in intimate registering relation the mouth of the plastic refuse bag, the back wall having a relatively much smaller inlet opening registering with the chute and in a position so that the flow from the chute is discharged in a concentrated straight stream through the large central opening directly into the mouth of the bag, at least a portion of the walls being formed of porous fabric, all of the air in the incoming stream entering the bag being turned back through the space surrounding the incoming stream for venting through the porous fabric so that dust and chaff entrained in the turned-back air is captured on the walls of the fabric, the inlet opening providing a loose slip joint connection with respect to the chute and the front and back walls of the enclosure being rigidly supported with respect to the bottom wall to permit the enclosure with the connected bag to be disconnected from the chute and swung into a bag-vertical position for bodily shaking and for dislodgement from the fabric and into the mouth of the bag the captured dust and chaff.
Claim 2
Dependent Claim

In a bagging attachment for use with a shredding machine having a discharge chute for discharging shredded garden waste in an airborne stream spaced parallel to the ground and for use with a plastic film refuse bag, the combination comprising an enclosure having front, back, top, bottom and side walls connected together about their edges, the front wall being of narrow picture-frame configuration defining a large central opening and having means for securing thereto in intimate registering relation the mouth of the plastic refuse bag, the back wall having a relatively much smaller inlet opening registering with the chute and in a position so that the flow from the chute is discharged in a concentrated straight stream through the large central opening directly into the mouth of the bag, at least a portion of the walls being formed of porous fabric, all of the air in the incoming stream entering the bag being turned back through the space surrounding the incoming stream for venting through the porous fabric so that dust and chaff entrained in the turned-back air is captured on the walls of the fabric, the inlet opening providing a loose slip joint connection with respect to the chute and the front and back walls of the enclosure being rigidly supported with respect to the bottom wall to permit the enclosure with the connected bag to be disconnected from the chute and swung into a bag-vertical position for bodily shaking and for dislodgement from the fabric and into the mouth of the bag the captured dust and chaff.
Claim 3
Dependent Claim
69 words
The combination as claimed in claim 1 in which the means for securing the bag includes a hoop member conforming to the picture frame configuration of the front wall and over which the mouth of the bag is registeringly folded, and means on the front wall for captively engaging the hoop with the bag in place to form a tight joint between the enclosure and mouth of the bag.
Claim 4
Dependent Claim
57 words
The combination as claimed in claim 1 in which the top and side walls are formed of a single rectangular length of fabric having securing means distributed along the edge thereof for substantially continuous edge-to-edge attachment to the cooperating portion of the enclosure, the securing means being readily disengageable to permit removal of the length of fabric.
Claim 5
Dependent Claim
256 words
The combination of a shredding machine having a discharge chute, a bagging attachment, and a refuse bag, the opening in the bag being spaced apart from the discharge chute, the bagging attachment being interposed directly between the discharge chute and the opening in the bag, the attachment being an enclosure having an inlet opening, an outlet opening, and a filtering element, the inlet opening being in direct generally alined communication with the outlet opening, the inlet opening being alined with the discharge chute, and the outlet opening being alined with the opening in the bag, so that the flow from the discharge chute is discharged in a concentrated undiverted stream into the inlet opening of the attachment, through the attachment, and into the mouth of the bag, bag securement means cooperatively associated with the enclosure for holding the mouth of the refuse bag in an open configuration and securing the mouth around the outlet opening and to the enclosure, the filtering element being a porous portion of the walls of the enclosure, the bag being formed of non-porous material so that the porous portion of the enclosure provides the sole communication between the interior of the bag and the atmosphere surrounding the bagging attachment, the outlet opening being substantially larger in cross section tHan the inlet opening and the incoming stream whereby all of the air in the incoming stream entering the bag is turned back and passes through the space surrounding the incoming stream and is vented through the filtering element of the bagging attachment.
