Definitions
- the present invention generally relates to compaction machines, such as those used to compact landfills and, more particularly, to an improved wire guard for use on the wheels of the compaction machines.
- wire guards are used to prevent refuse from wrapping around the axles.
- Previously known wire guards were constructed of steel plate and supporting gussets that were welded together, or steel plated with steel castings welded together. Because these previously known wire guards were constructed of multiple parts, they occasionally required hardfacing with alloy welding wire to extend their wear life.
- Some of these wire guards additionally include cleats turned sideways at the edge of the wheel. However, because cleats are tapered on both sides, the wire guard is not completely at the edge of the wheel, potentially providing a path for wire to enter and also preventing edge to edge compaction from the wheel.
- the claimed wire guard is cast steel as a single part. As a result, it can be heat treated to through harden it, thus, reducing the need for hardfacing.
- the wire guard is made of segments that include a center cleat to provide additional traction. However, the wire guard extends all the way to the edge of the wheel.
- the wire guard requires no fabrication and can be welded in place. This is a significant advantage over other wire guards that require expensive and time-consuming fabrication.
- the wire guard may also have a drop down lip that allows the wire guard to protect the lateral edge of the wheel wrapper.

- FIG. 1A depicts a compactor wheel 4 with one embodiment of the wire guard 2 invention as disclosed herein.
- the wire guard 2 is mounted on the lateral edge 12 of the wheel wrapper 3 closest to the axle of the compactor (the “lateral side”).
- the wire guard 2 is affixed to the wheel 4 by welding.
- the wire guard 2 is affixed along the lateral edge 12 at cleats 8 .
- some space is created between the edge of the tapered side of each segment 6 and the lateral edge 12 of the compactor wheel 4 .
- the wire guard 2 is affixed along the lateral edge 12 at cleats 8 and flanges 18 , in which the lateral side of the wheel guard 2 is flat such that no space is created between the edge of the tapered side of each segment 6 and the lateral edge 12 of the compactor wheel 4 .
- the application of the wheel guard 2 directly to the lateral edge 12 of the wheel wrapper 3 provides more compaction area than known wheel guards made from welding flanges to casted cleats.
- the width of the wire guard 2 should be such that wires, ropes, and other debris are prevented from wrapping around the compactor axle.
- the width of the segments 6 is 7.25 inches from the base to the top of the cleat. In a preferred embodiment, the width of the segments 6 is 8.25 inches from the base to the top of the cleat. The width could, however, be narrower or wider.
- the wire guard 2 is comprised of a series of segments 6 that are welded directly to the compactor wheel 4 .
- the wire guard 2 can be comprised of any number of segments 6 as necessary to complete the circumference of the compactor wheel 4 .
- the wire guard 2 is made of eight (8) segments 6 that circumscribe the wheel 4 .
- Each segment 6 is made of cast steel. This is particularly advantageous over the prior art that required fabricated flanges on cleat castings, or gussets. It should also be appreciated that segment 6 can be heat treated to through harden it and extend the wear life. The through hardened casting also provides consistent wear of the wire guard segment 6 , including the cleat 8 and flange 18 . Any known method in the art for heat treating for through heating cast steel may be used.
- Previously known wire guards required hardfacing with alloy welding wire to increase the wear life.
- the manufacturing and/or installation process for hardfacing adds extra welding and expense to the known wheel guards.
- These known wheel guards also require periodic maintenance of hardfacing as the wheel guard wears.
- Another advantage of the disclosed invention is that the steel casting provides uniform wear of the cleats 8 and the wheel guard flanges 18 , while some known wheel guards combined cleats and welded flanges that would unevenly wear with use.
- each segment 6 can be welded to the lateral edge 12 of the compactor wheel 4 at lateral side weld 13 and distal side weld 11 and to each other at segment-segment lateral side weld 7 and segment-segment distal side weld 5 as they are installed radially around the outer edge of the wheel wrapper 3 with the outer surface of the wheel 4 that contains features, such as the cleats 8 , used for traction.
- the lateral side weld 13 must be done at the lateral edge 12 interior side of the wheel wrapper 3 (not shown). Compared to the prior art, it is much easier to install the segments 6 onto the wheel 4 .
- the casted segments 6 are designed to be flat and perpendicular on the horizontal outside lateral edge 12 of the wheel wrapper 3 , thereby reducing or eliminating wear on the outside lateral edge 12 of the wheel wrapper 3 .
- the installer does not have to weld fabricated flanges to cleat castings or gussets on other fabricated versions. Because the segments 6 include both the cleat 8 and the flanges 18 , the need for a gusset or other members for attaching the segments 6 to the wheel wrapper and/or other segments is eliminated. Additionally, because it is cast, weld fillets can be integrated into the design for easier, stronger, and less expensive welding.
- each segment 6 has a flange 18 that is made of a primarily flat side 14 , which will be closest to the axle, and a tapered side 16 .
- the tapered design can be appreciated in FIGS. 2B , 2 C, 2 E, and 2 F.
- the primarily flat side 14 does not require perfect flatness.
- each segment can have two tapered sides 16 .
- each segment has two flat sides 14 .
- the tapered side 16 includes a center cleat 8 , as can be appreciated in FIGS. 2A-2D .
- the center cleat 8 provides additional traction for the compactor and increases wear life of the wire guard 2 by reducing or eliminating spinning and slipping of the compactor wheel 4 when climbing on logs and hard objects.
- the center cleat 8 and the flange 18 are more resistant to wear as a result of the optional through-hardening of the casting.
- the tapered design of the flange 18 and center cleat 8 allows for longer wear life and penetration of trash and refuse as the wire guard 2 wears.
- the cleat 8 need not be perfectly centered in each segment 6 .
- the segments 6 may contain a drop down lip 10 , as shown in FIGS. 2E and 2F .
- Each flange 18 also includes at its terminal edge an off-set/overlapping flange edge 20 that is complementary to the adjacent flange 18 . This allows the flanges 18 to be welded to each other. It additionally allows the wire guard 2 to accommodate imprecisions in wheel circumference due to wearing down of the wheel wrapper 3 or rebuilding of the wheel 4 . Larger overlapping flange edges 20 permit larger variations in wheel circumference.
- FIGS. 3A-3F show an additional feature of the preferred embodiment.
- Each segment 6 may also have an overhanging lip, referred to herein as the drop down lip 10 , which is a piece of metal that extends over the edge of the wheel 4 toward the axle.
- the size of this drop down lip 10 may vary, but in one embodiment, the drop down lip 10 extends as much as 1.25 inches, shown in FIG. 3F . In another embodiment, the drop down lip 10 extends as much as 0.25 inches, shown in FIG. 3D . In still another embodiment, the drop down lip 10 extends as much as 0.5 inches, shown in FIG. 3E .
- the drop down lip 10 provides several advantages. First, the drop down lip 10 protects the lateral outside edge of the wheel wrapper 3 , thereby eliminating wear on this edge.
- the drop down lip 10 provides additional surface area for welding. This is particularly useful in instances where the outside horizontal surface of the wheel wrapper 3 has become worn and tapered, making it difficult to weld a wire guard 2 to the wrapper 3 .
- the drop down lip 10 allows the segment 6 to be welded to the inside of the wheel wrapper 3 , which would not be worn because it does not come into contact with refuse.
- FIGS. 4A-4F illustrate yet another embodiment of the present invention each segment 6 has a flange 18 that is made of a primarily flat side 14 , which will be closest to the axle, a tapered side 16 , and without the drop down lip 10 .
- the construction of the wire guard 2 with lack of a drop down lip 10 can be appreciated in FIG. 1B , which allows for easy installment by welding only on the outside of the wheel wrapper 3 .
- the tapered design can be appreciated in FIGS. 4B , 4 C, 4 E, and 4 F.
- the primarily flat side 14 does not require perfect flatness.
- each segment has two flat sides 14 .
- the tapered side 16 includes a center cleat 8 , as can be appreciated in FIGS.
- the center cleat 8 provides additional traction for the compactor and increases wear life of the wire guard 2 by reducing or eliminating spinning and slipping of the compactor wheel 4 when climbing on logs and hard objects. As previously indicated, the center cleat 8 and the flange 18 are more resistant to wear as a result of the optional through-hardening of the casting. The tapered design of the flange 18 and center cleat 8 allows for longer wear life and penetration of trash and refuse as the wire guard 2 wears. The cleat 8 need not be perfectly centered in each segment 6 . Each flange 18 also includes an off-set/overlapping flange edge 20 that is complementary to the adjacent flange 18 , which can be seen in FIG. 4D .
- the wire guard 2 described herein provides many advantages over the prior art, including requiring fewer pieces and less welding, and the ability to be installed without requiring fabrication of a custom guard. Additionally, it is through hardened, thus reducing wear on its features, and it protects the lateral edge 12 of the wheel wrapper 3 .

Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 61/697,470 by Crystal and Griffiths, filed Sep. 6, 2012, which is incorporated herein by reference in its entirety.
- The present invention generally relates to compaction machines, such as those used to compact landfills and, more particularly, to an improved wire guard for use on the wheels of the compaction machines.
- Compaction machines, which are used to compact landfills, encounter the problem of wire, rope, cable, and other trash becoming wrapped around the axles of the compactor machines. As a result, the compactor wheel, axles, and seals can become damaged and require replacement and significant downtime. Typically, wire guards are used to prevent refuse from wrapping around the axles. Previously known wire guards were constructed of steel plate and supporting gussets that were welded together, or steel plated with steel castings welded together. Because these previously known wire guards were constructed of multiple parts, they occasionally required hardfacing with alloy welding wire to extend their wear life. Some of these wire guards additionally include cleats turned sideways at the edge of the wheel. However, because cleats are tapered on both sides, the wire guard is not completely at the edge of the wheel, potentially providing a path for wire to enter and also preventing edge to edge compaction from the wheel.
- An improved wire guard design is presented herein. The claimed wire guard is cast steel as a single part. As a result, it can be heat treated to through harden it, thus, reducing the need for hardfacing. The wire guard is made of segments that include a center cleat to provide additional traction. However, the wire guard extends all the way to the edge of the wheel.
- The wire guard requires no fabrication and can be welded in place. This is a significant advantage over other wire guards that require expensive and time-consuming fabrication.
- The wire guard may also have a drop down lip that allows the wire guard to protect the lateral edge of the wheel wrapper.
- Further advantages of the invention will become apparent by reference to the detailed description of preferred embodiments when considered in conjunction with the drawings:

For purposes of explanation, specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that these specific details are not required to practice the invention. Descriptions of specific applications are provided only as representative examples. Various modifications to the preferred embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the scope of the invention. The present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest possible scope consistent with the principles and features disclosed herein.
- Referring to the drawings,
FIG. 1A depicts a compactor wheel 4 with one embodiment of thewire guard 2 invention as disclosed herein. Thewire guard 2 is mounted on thelateral edge 12 of thewheel wrapper 3 closest to the axle of the compactor (the “lateral side”). In preferred embodiments, thewire guard 2 is affixed to the wheel 4 by welding. As can be appreciated inFIG. 1A , thewire guard 2 is affixed along thelateral edge 12 atcleats 8. In this embodiment, some space is created between the edge of the tapered side of eachsegment 6 and thelateral edge 12 of the compactor wheel 4. In another embodiment, as shown inFIGS. 1B and 1C , thewire guard 2 is affixed along thelateral edge 12 atcleats 8 andflanges 18, in which the lateral side of thewheel guard 2 is flat such that no space is created between the edge of the tapered side of eachsegment 6 and thelateral edge 12 of the compactor wheel 4. The application of thewheel guard 2 directly to thelateral edge 12 of thewheel wrapper 3 provides more compaction area than known wheel guards made from welding flanges to casted cleats. The width of thewire guard 2 should be such that wires, ropes, and other debris are prevented from wrapping around the compactor axle. In one embodiment, the width of thesegments 6 is 7.25 inches from the base to the top of the cleat. In a preferred embodiment, the width of thesegments 6 is 8.25 inches from the base to the top of the cleat. The width could, however, be narrower or wider. - The
wire guard 2 is comprised of a series ofsegments 6 that are welded directly to the compactor wheel 4. Thewire guard 2 can be comprised of any number ofsegments 6 as necessary to complete the circumference of the compactor wheel 4. In a preferred embodiment, thewire guard 2 is made of eight (8)segments 6 that circumscribe the wheel 4. Eachsegment 6 is made of cast steel. This is particularly advantageous over the prior art that required fabricated flanges on cleat castings, or gussets. It should also be appreciated thatsegment 6 can be heat treated to through harden it and extend the wear life. The through hardened casting also provides consistent wear of thewire guard segment 6, including thecleat 8 andflange 18. Any known method in the art for heat treating for through heating cast steel may be used. Previously known wire guards required hardfacing with alloy welding wire to increase the wear life. The manufacturing and/or installation process for hardfacing adds extra welding and expense to the known wheel guards. These known wheel guards also require periodic maintenance of hardfacing as the wheel guard wears. Another advantage of the disclosed invention is that the steel casting provides uniform wear of thecleats 8 and thewheel guard flanges 18, while some known wheel guards combined cleats and welded flanges that would unevenly wear with use. - After through hardening the casting, each
segment 6 can be welded to thelateral edge 12 of the compactor wheel 4 atlateral side weld 13 anddistal side weld 11 and to each other at segment-segment lateral side weld 7 and segment-segmentdistal side weld 5 as they are installed radially around the outer edge of thewheel wrapper 3 with the outer surface of the wheel 4 that contains features, such as thecleats 8, used for traction. For still other embodiments that contain a drop downlip 10, it is evident that thelateral side weld 13 must be done at thelateral edge 12 interior side of the wheel wrapper 3 (not shown). Compared to the prior art, it is much easier to install thesegments 6 onto the wheel 4. In some embodiments, thecasted segments 6 are designed to be flat and perpendicular on the horizontal outsidelateral edge 12 of thewheel wrapper 3, thereby reducing or eliminating wear on theoutside lateral edge 12 of thewheel wrapper 3. The installer does not have to weld fabricated flanges to cleat castings or gussets on other fabricated versions. Because thesegments 6 include both thecleat 8 and theflanges 18, the need for a gusset or other members for attaching thesegments 6 to the wheel wrapper and/or other segments is eliminated. Additionally, because it is cast, weld fillets can be integrated into the design for easier, stronger, and less expensive welding. - As will be appreciated from
FIGS. 2A-2F , eachsegment 6 has aflange 18 that is made of a primarilyflat side 14, which will be closest to the axle, and atapered side 16. The tapered design can be appreciated inFIGS. 2B , 2C, 2E, and 2F. The primarilyflat side 14 does not require perfect flatness. In another embodiment, such as shown inFIG. 1A , each segment can have two taperedsides 16. In still another embodiment, each segment has twoflat sides 14. In a preferred embodiment, the taperedside 16 includes acenter cleat 8, as can be appreciated inFIGS. 2A-2D . Thecenter cleat 8 provides additional traction for the compactor and increases wear life of thewire guard 2 by reducing or eliminating spinning and slipping of the compactor wheel 4 when climbing on logs and hard objects. As previously indicated, thecenter cleat 8 and theflange 18 are more resistant to wear as a result of the optional through-hardening of the casting. The tapered design of theflange 18 andcenter cleat 8 allows for longer wear life and penetration of trash and refuse as thewire guard 2 wears. Thecleat 8 need not be perfectly centered in eachsegment 6. Optionally, thesegments 6 may contain a drop downlip 10, as shown inFIGS. 2E and 2F . - Each
flange 18 also includes at its terminal edge an off-set/overlappingflange edge 20 that is complementary to theadjacent flange 18. This allows theflanges 18 to be welded to each other. It additionally allows thewire guard 2 to accommodate imprecisions in wheel circumference due to wearing down of thewheel wrapper 3 or rebuilding of the wheel 4. Larger overlapping flange edges 20 permit larger variations in wheel circumference. -
FIGS. 3A-3F show an additional feature of the preferred embodiment. Eachsegment 6 may also have an overhanging lip, referred to herein as the drop downlip 10, which is a piece of metal that extends over the edge of the wheel 4 toward the axle. The size of this drop downlip 10 may vary, but in one embodiment, the drop downlip 10 extends as much as 1.25 inches, shown inFIG. 3F . In another embodiment, the drop downlip 10 extends as much as 0.25 inches, shown inFIG. 3D . In still another embodiment, the drop downlip 10 extends as much as 0.5 inches, shown inFIG. 3E . The drop downlip 10 provides several advantages. First, the drop downlip 10 protects the lateral outside edge of thewheel wrapper 3, thereby eliminating wear on this edge. Second, the drop downlip 10 provides additional surface area for welding. This is particularly useful in instances where the outside horizontal surface of thewheel wrapper 3 has become worn and tapered, making it difficult to weld awire guard 2 to thewrapper 3. The drop downlip 10 allows thesegment 6 to be welded to the inside of thewheel wrapper 3, which would not be worn because it does not come into contact with refuse. -
FIGS. 4A-4F illustrate yet another embodiment of the present invention eachsegment 6 has aflange 18 that is made of a primarilyflat side 14, which will be closest to the axle, atapered side 16, and without the drop downlip 10. The construction of thewire guard 2 with lack of a drop downlip 10 can be appreciated inFIG. 1B , which allows for easy installment by welding only on the outside of thewheel wrapper 3. The tapered design can be appreciated inFIGS. 4B , 4C, 4E, and 4F. The primarilyflat side 14 does not require perfect flatness. In still another embodiment, each segment has twoflat sides 14. In a preferred embodiment, the taperedside 16 includes acenter cleat 8, as can be appreciated inFIGS. 4A-4C . Thecenter cleat 8 provides additional traction for the compactor and increases wear life of thewire guard 2 by reducing or eliminating spinning and slipping of the compactor wheel 4 when climbing on logs and hard objects. As previously indicated, thecenter cleat 8 and theflange 18 are more resistant to wear as a result of the optional through-hardening of the casting. The tapered design of theflange 18 andcenter cleat 8 allows for longer wear life and penetration of trash and refuse as thewire guard 2 wears. Thecleat 8 need not be perfectly centered in eachsegment 6. Eachflange 18 also includes an off-set/overlappingflange edge 20 that is complementary to theadjacent flange 18, which can be seen inFIG. 4D . This allows theflanges 18 to be welded to each other. It additionally allows thewire guard 2 to accommodate imprecisions in wheel circumference due to wearing down of thewheel wrapper 3 or rebuilding of the wheel 4. Larger overlapping flange edges 20 permit larger variations in wheel circumference. - The
wire guard 2 described herein provides many advantages over the prior art, including requiring fewer pieces and less welding, and the ability to be installed without requiring fabrication of a custom guard. Additionally, it is through hardened, thus reducing wear on its features, and it protects thelateral edge 12 of thewheel wrapper 3. - The terms “comprising,” “including,” and “having,” as used in the claims and specification herein, shall be considered as indicating an open group that may include other elements not specified.
