  "title": "Loading and unloading apparatus and method incorporating sliding floor system",
  "abstract": "A method and apparatus for loading a batch of turkeys or other cargo into multilayer containers. A method of unloading the turkeys or cargo from the multilayer containers. Each container or coop includes a liftable gate at each end that enables access into the container through either end, and a slidably moveable floor positioned over a rigid permanent floor. As the turkeys are introduced into the containers, the slideable floor is retracted into the container, pulling the bird farther back into the container. Similarly, to unload the turkeys, the slideable floor is extracted from the container, moving the birds out of the container. A removable holding wall may be located at the end of the slideable floor to urge any hesitant turkeys out of the container.",
  "claims": [
    "1. An apparatus for loading or unloading turkeys from a coop, the coop having sidewalls, end walls, a permanent floor, and a moveable flexible floor overlying the permanent floor, a moveable gate in at least one end wall of the coop, the gate for selectively opening and closing an access port into the coop cavity, the apparatus comprising: (a) a floor extracting mechanism adapted and configured to extract the moveable flexible floor from over the permanent floor and out from the coop through the access port; and (b) a floor retracting mechanism adapted and configured to retract the moveable flexible floor over the permanent floor and into the coop.",
    "2. The apparatus of claim 1, wherein the moveable floor slides over the permanent floor.",
    "3. The apparatus of claim 2, wherein the floor extracting mechanism comprises a strap adapted for attachment to an end of the moveable floor and a winch.",
    "4. The apparatus of claim 3, wherein the floor extracting mechanism is positioned on a moveable turkey loader assembly.",
    "5. The apparatus of claim 3, wherein the floor extracting mechanism is positioned on a fixed turkey unloading assembly.",
    "6. The apparatus of claim 2, wherein the floor retracting mechanism comprises a cable adapted for attachment to an end of the moveable floor and a winch.",
    "7. The apparatus of claim 6, wherein the floor retracting mechanism is positioned on a moveable vehicle.",
    "8. The apparatus of claim 6, wherein the floor retracting mechanism is positioned on a fixed turkey unloading assembly.",
    "9. A method of loading turkeys to a transport coop of the type having four walls, a slideable floor positioned on a permanent floor, and an openable gate in two opposite sidewalls, the gates closing an access port into the coop, the method comprising the steps of: (a) extracting at least a portion of the slideable floor out of the coop; (b) positioning a turkey on the extracted floor; and (c) retracting the slideable floor with the turkey thereon into the coop, wherein the step of extracting is accomplished by hooking a first cable to an end of the slideable floor and pulling the slideable floor out of the coop, and further wherein the step of retracting is accomplished by hooking a second cable to another end of the slideable floor and pulling the slideable floor into the coop.",
    "10. A method of unloading turkeys to a transport coop of the type having four walls, a slideable floor positioned on a permanent floor, and an openable gate in two opposite sidewalls, the gates closing an access port into the coop, the method comprising the steps of: (a) extracting at least a portion of the slideable floor out of the coop; (b) removing a turkey from the extracted floor so that no turkeys remain on the floor; and (c) retracting the slideable floor into the coop, wherein the step of extracting is accomplished by hooking a first cable to an end of the slideable floor and pulling the slideable floor out of the coop, and further wherein the step of retracting is accomplished by hooking a second cable to another end of the slideable floor and pulling the slideable floor into the coop.",
    "11. The method of claim 10, wherein the step of extracting further includes attaching a removable holding wall to the slideable floor.",
    "12. A method of loading turkeys into a transport coop of the type having four walls, a slideable floor positioned on a permanent floor, and an openable gate in one sidewall, the gate closing an access port into the coop, the method comprising the steps of: (a) extracting at least a portion of the slideable floor out of the coop through the access port; (b) positioning a turkey on the extracted floor; and (c) retracting the slideable floor with the turkey thereon into the coop, wherein the step of extracting is accomplished by pulling the slideable floor out of the coop, and further wherein the step of retracting is accomplished by pulling the slideable floor into the coop.",
    "13. A method of unloading turkeys from a transport coop of the type having four walls, a slideable floor positioned on a permanent floor, and an openable gate in one sidewall, the gate closing an access port into the coop, the method comprising the steps of: (a) extracting at least a portion of the slideable floor out of the coop through the access port; (b) removing a turkey from the extracted floor so that no turkeys remain on the floor; and (c) retracting the slideable floor into the coop, wherein the step of extracting is accomplished by pulling the slideable floor out of the coop, and further wherein the step of retracting is accomplished by pulling the slideable floor into the coop."

Nos. 5,388,948 issued Feb. 14, 1995; 5,466,116 issued Nov. 14, 1995; 5,505,582 issued Apr. 19, 1996; and 5,735,664 issued Apr. 7, 1998; and pending U.S. patent applications Ser. No. 08/874,084, filed Jun. 12, 1997 now abandoned, entitled Turkey Coop Unloading Apparatus and Method, and Ser. No. 08/960,278, now U.S. Pat No. 6,048,157 filed Oct. 29, 1997, entitled Turkey Coop Unloading Apparatus and Method, are hereby incorporated by reference.\n\nThis invention relates generally to the loading and unloading of contents of multi-layered containers, and more particularly to a method and apparatus for loading and unloading live poultry, and particularly turkeys, to and from a plurality of multilevel coops on a transport truck, with minimal damage to the turkeys.\n\nPoultry, and in particular turkeys, is typically housed for transport to processing plants in multi-layered cages, coops or containers carried by a large transport vehicle such as a flatbed trailer truck. Loading the turkeys into the coops at the farm in a systematic manner so as to avoid piling or congestion of the turkeys in the loading area and to avoid damage to the turkeys has long been a problem. Further, unloading the turkeys, for example at a processing facility, is further a problem for the same reasons.\n\nIt will be understood that while the invention hereafter is described with respect to the handling and processing of turkeys from transport trucks, the principles of this invention are not to be limited thereby.",
