A separately attachable poultry perching device and system, specifically for use with a hexagonal shaped pully wired poultry feed trough.
Large scale production and retail distribution of free range and cage free poultry eggs are held to special regulation for certification standards. Detailed management standards for laying hens are outlined by the Humane Farm Animal Care Animal Care Standards, Egg Laying Hens (2017 Standards). These rules are regularly updated to meet the evolving technology and goals. While the topics are outlined separately in the regulations, actual management practices are very much intertwined in their design and effect on the farm. The design of an egg laying operation that meets certification standards can be challenging to achieve. There are limitations among existing equipment technology which makes for cumbersome and inefficient work. Indoor feed systems must be raised above the seated ground by a given height and separated from each other by required distance. Due to frequent cleaning of debris underneath the feed trough, current trough systems are designed to be hung from a barn roof for raising by pully system during cleaning phase and to be lowered back into position after cleaning is completed. This design is currently the accepted standard design within the industry for meeting certification requirements. The design offers an acceptable level of efficiency on the farm, minimizing the amount of labor needed to organize the barn for cleaning.
Apart from regulation that controls practices relating to indoor feeding are requirements pertaining to the design of indoor perching. According to the Humane Farm Animal Care Animal Care Standards, Egg Laying Hens (2017 Standards), at least 20% of all perches must be elevated above the floor space by a minimal distance (more than 16″ and under 1 meter above the floor space) and accommodate a certain density of hens per square foot space. It is likely soon with rule amendments that 100% of perches will need to be elevated above floor space for improved conditions as commercial demand grows. Perches must further sufficiently accommodate 6″ of perch length per hen for the given density of hens within the barn area. Round perch bars must be at least 1″ in diameter and no greater than 3″ round, without sharp edges and having no less than 0.5″ gap space on either side to allow for proper and safe gripping.
Existing perching equipment are not designed to coordinate well with the standard pully-lift feed equipment. One existing perch design comprises lengths of perch bars separately held on pully lift lines connected to barn rafters. By this design, both perch bars and feed troughs are lifted up to rafter level for proper barn clearance when tall tractor equipment must be brought to clean the barn. The total weight of suspended feed troughs together with the weight of suspended perch bars weigh heavily on barn roof rafters, significantly wearing down the life span of barn infrastructure. Installation of this type of system is also more costly and cumbersome due to the need to install pully devices on the rafters. Any adjustment to the location or number of perch bars in the barn would require removal and reinstallation of pullies to meet design requirement. Precision of installation is further required as the location where the wires are installed on the rafter dictates their proximity to the troughs below. Wire suspended perch system is essentially costly, inefficient and inflexible to management.
Yet another alternative perch design provides an “A-frame” scaffolding system constructed around the feed trough to achieve elevation and spacing requirement. The perch bars are seated lengthwise along a scaffold device which raises the perch bars above ground in multi-tier fashion. When the bar is to be cleaned, the A-frame scaffolding device would be disassembled to enable pully-lift of the feed troughs and reassembled upon lowering of the troughs when cleaning is completed. This system is labor intensive and inefficient. Larger barns either require more units of this device to accommodate the lengths of feed trough and hen density, which in turn makes for more cumbersome assembly and disassembly process. Many individual hands are required to construct the A-frame scaffolding device around the hanging feed trough to avoid damage or injury to nearby equipment. A great deal of labor and work hours is expended by this design. Installers are further subjected to stay in the barn for longer periods of time, surrounded by unhealthy poultry manure and dust particles.
U.S. Pat. No. 3,050,030, filed Jun. 1, 1961, provides another feed trough and perch design disclosing a multi-tiered feed trough interconnected vertically above each other within an open crate environment and having perch stands connected thereto. This system is designed for hobbyist operation with smaller number of birds. The design itself would likely create too dense of an environment to properly conform with current stringent spatial requirements.
A considerable need remains for an inventive solution that improves upon indoor perch design and management systems that conforms with regulatory standards of the industry. There remains a need for a more efficient system of management, that is safer to handle, and has the capability of accommodating more than minimum certification requirements, particularly as the rules continue to become more stringent and as demand continues to grow.

The invention herein pertains to a separately attachable poultry perching system and device, specifically to be utilized with long poultry feed troughs hung from barn rafters. The device comprising separately attachable and detachable components for assembly onto an already assembled and in place poultry feed trough device and system. The particular poultry feed trough device and system contemplated by this application is a long feed trough that is hung from barn rafters by retractable or liftable pully means. The long feed trough preferably having a consistent cross-sectional shape along its length which may either be geometric or round in nature or a combination of both. The cross sectional shape of said poultry feed trough is preferably hexagonal in nature according to current standards but may also embody other geometric or rounded shapes. The device of this invention is intended to be easily and safely assembled by one or more individual, wherein the device by its separate components separately surround one or more ends of a long poultry feed trough in a yoke like manner. The device assists to lift the feed trough slightly off the ground surface, providing lift support and therefore alleviating pulling pressure against the barn rafter along the pully lines from where the troughs typically hang. At least two or more such device units are attached along the length of said long feed trough, cradling said feed trough securely and stably on the ground surface while allowing for a taught connection between the pully lift system and the top portion of the feed trough. The combined affect comprising a pully line connection to the top of the feed trough which prevents tipping of the feed trough and further a ground support system in the device to provide stability and alleviate wear against the barn rafters.
The device of this invention further providing means for attaching perch bars parallel to the length of said long feed trough. Each said device unit further comprising a flat planar piece serving as a bridge which fits within said device unit and extends beyond the left and right sides of said device unit, extending a distance to the left and right side of said long feed trough. The bridge portion having a plurality of circular perforations therethrough of the same diameter as a perch bar. Wherein two or more device units being attached to said long feed trough, supporting said feed trough above the ground level in stable manner, and wherein further one or more perch bar is sleeved through at least one of said circular perforation of said bridge portion. Said one or more perch bar being supported above the ground surface at either side of said long feed trough and having minimum to no pull effect against the rafters along said pully lift system due to the ground-lift support provided by said two or more device units.
The device of this invention comprising a bracket portion, a bridge portion, and one or more perch bar. Said bracket portion comprising individual bracket units that each comprise two identically shaped plates (also referred to interchangeably as half bracket pieces). During assembly, each half of said two half bracket pieces are positioned to face each other in flush manner and wrap around the cross-section of a pentagonal shaped feed trough forming a yoke like support around the feed trough. Each of said two half bracket pieces are separately attachable and detachable from said feed trough without changing the position of said feed trough. This may be achieved by separately wrapping each half around the left and right sides of said feed trough cross section. The two half bracket pieces may comprise completely separate portions or alternatively interconnected at the top end by swivel connection. The ability to separate each half bracket piece from each other allows each bracket unit to be assembled and disassembled without disturbing surrounding equipment and safely by a single individual.
Each half bracket piece of said two half bracket pieces for each bracket unit further centrally having an indentation centrally on the same side edge, which may be the left or right side edge, comprising half the cross-sectional shape of said long feed trough. Each said half bracket piece also having an indentation at its each top end with the shape of a semi-circle. The indentations at the top end and centrally should be on the same side edge of the overall bracket piece. Each half bracket piece further having a first and second side. Said first side comprising a flat planar surface. Said second side comprising a flat surface and further providing a first planar ledge perpendicularly extending from said half pentagonal indentation and a second planar ledge perpendicularly extending from said bottom ledge forming a toe-hook.
The two half bracket pieces, when combined in overlapping manner around the cross section of said feed trough surrounds the feed trough much like a yoke, lifting said trough above the ground surface at a predetermined height. The first planar ledge of each of the combined half bracket pieces facing opposite direction away from each other, forming a horizontal shelf. Said horizontal shelf providing vertical support to the bottom surface of said feed trough. The second planar ledge of each of the combined half bracket pieces also facing opposite direction away from each other and forming a horizontal extension at the ground level, giving the device overall footing and stability. At the edge of each second planar ledge exists at least one perpendicular extension approximately but no greater than 1.5 inch wide, also referable as a toe-hook piece. Each said toe-hook piece is intended to be sleevable through a perforation on the ground surface. It is worthy to note that the ground surface of a typical indoor poultry bar comprises a raised grid flooring system with approximately 1 inch square perforations to allow collection of debris underneath. The ground surface, as referenced within the poultry management industry, refers to the supporting surface which may be raised above the actual ground level. The toe-hook as it is sleeved through the ground surface, helps to hold the overall device and system in more rigid position to prevent lateral shifting against movement of the hens. The toe-hook piece is in fact a small vertical piece extending perpendicularly from said bottom ledge. Said toe-hook piece is preferably not greater or less than 90 true vertical so as to avoid actual hooking and retention onto the perforated ground surface. This is important because the feed trough and device assembly are intended to be lifted together in tandem by said pully lift system and should be able to be removed and reset without interference or additional assistance. Each half bracket piece being identical in shape for ease of manufacturing, catalogue packaging and sale in parts.
Each device unit further comprising a bridge that is straight and flat in shape with holes strategically perforated centrally along its length. At either ends are U-shaped grooves or alternatively circular perforations. Each U-shaped groove or circular perforation is intended to accommodate a perch bar. Said U-shaped groove portion may cradle a perch bar while the semi-circle indentation of the top portion of a first half bracket wraps around a left side of said perch bar and a semi-circle indentation of the top portion of a second half bracket wraps around the right side of said perch bar. The effect comprising a perch bar being completely surrounded by a yoke feature and suspended above the feed trough by a pre-determined distance. The benefit of this particular design allows for a perch bar to be placed in suspension without actual sleeving of the bar through a hole but rather by mere assembly of the individual components of the device. The circular perforations along said bridge portion would require actual sleeving of said perch bar therethrough.
Essentially, the bridge portion being positioned between a first and second half bracket piece at the top end, surrounding a perch bar that is positionable and suspendable above said feed trough. The entire assembly of said bracket unit surrounding said feed trough and perch bar(s) is seatable above said ground surface while connected to said pully lift system. Upon full assembly, the components of said device of this invention (the two half bracket pieces and bridge surrounding said perch bar and feed trough) are removably connected in place by bolting or screwing means. Two parallel adjacent feed troughs may be tandemly connectable by a bridge portion between their respective bracket unit assemblies with at least two or more perch bars positionable through said bridge portion. Alternatively, each feed trough maintains its own stand-alone position but with one or more perch bar suspended parallel to its length by assembly of this invention.
Other features, advantages, and object of the present invention will become more apparent and be more readily understood from the following detailed description, which should be read in conjunction with the accompanying drawings.
A preferred embodiment of the invention herein is provided according to
