Abstract: An improved device for covering a laboratory animal feeder, specifically adapted for retrofitting to an existing laboratory animal feeder, which includes an inclined, flanged cover to decrease the likelihood of contaminants entering the feeder. The invention also includes an attachment means which allows animal food to be quickly and easily entered into a feeder without detaching the cover from the feeder.

Abstract: A versatile feeder for use in an automated feeding system of the type used to raise domestic birds and animals on a commercial scale comprising a pan member for containing and presenting feed for consumption, feeder tube means disposed above said pan member and connectible with a feed conveyor source, said feeder tube means having upper and lower feed gates for directing feed supplied to said feeder tube means from said feed conveyor source into said pan member, and rotatable collar means surrounding said feeder tube means for controlling a first feed flow directed through said upper feed gate into said pan member independently of a second feed flow directed through said lower feed gate into said pan member. Associated wing members may also be provided on said rotatable collar means to prevent access to said first feed flow by said consuming birds and animals prior to the feed reaching a limited feeding area defined within the pan member.

Abstract: A vacuum-formed instant/disposable bird feeder for dispensing seeds into both sides of the feeder tray using a diverter projecting into the seed reservoir as shown in particular in FIG. 4 is disclosed. A controlled flow of the seed is achieved by the diverter and by adjusting the distance between the bottom of the filling spout and the feeder tray.

Abstract: A pig feeder includes a hopper in which a supply of feed is stored, and a feed trough mounted adjacent a lower end of the hopper and in communication with the hopper through an opening therein so that feed in the hopper can pass into the feed trough. The trough includes a bottom wall, a front wall extending upwardly from the bottom wall and having a top edge, and a top face having a width extending between the top edge of the front wall and the hopper. The top face has at least one feeding hole therethrough which is substantially U-shaped having a curved portion and a straight portion, the curved portion of the feeding hole being remote from the hopper. The diameter of the curved portion is preferably equal to the height of the front wall so that pigs feeding from the trough must reach vertically downwardly to get to the feed.

Abstract: A disposable one-piece pet feeding dish having a thin walled central bowl surrounded by a thin walled outwardly sloping skirt, the bottom of the central bowl being substantially flat and lying in the same plane as the lower edge of the dish's skirt, a patch covered with adhesive affixed to the flat outside surface of the bottom of the bowl, and a sheet of release paper covering the adhesive surface of the patch.

Abstract: An animal feeder of the type in which a feed hopper discharges feed downwardly onto a shelf which intercepts the feed so that it does not drop directly to a trough under the hopper and shelf but requires action by the animal to brush the feed off the shelf. In conjunction with the above, a water supply line runs closely beneath the shelf and has at least one fitting or nipple directed laterally outwardly over the trough from which nipple the animal may drink directly. The nipple is of the type minimizing discharge of water directly into the trough. The shelf is so fashioned as to substantially prevent the animal from eating feed directly from the shelf.

Abstract: A combination pet feeder consisting of a divided food and water bowl centered and anchored on a flat and colorful rubber mat. The mat catches all spillages while dog feeds. The bowl stays in position at all times.

Abstract: An animal feeding device includes a food container preferably shaped as a composite cylindrical can with seamed metal closures, one of which is easily openable. A base member is attachable to the food container through a food distribution coupling to secure the open end of the food container thereadjacent. The food distribution coupling includes a retaining ring for detachably securing the food distribution coupling to the food container to allow food to fall downwardly therefrom through the opening into a food distribution chamber in the coupling therebelow. A plurality of food distribution ports are adapted to receive food from the food distribution chamber for carrying same into the food trough of the base member. The feeding device is capable of stacking by attaching successive containers to the bottom of successively positioned base members through the use of additional retaining rings beneath food container.

Abstract: An animal feed distribution device that includes a feed conveyor system which fills animal feeding station feed supply bins from central storage. The bins are connected in parallel to the conveyor system, and they receive feed from the system in sequence. At least the last bin designed to receive feed contains an end-looking, infra-red emitting diode component, and a counterpart photo-transistor sensor component, the components providing input information to an electrical control system circuit as the result of the interruption or non-interruption of an infra-red beam passing between the components. The control system circuit activates or deactivates the conveyor system in response to such interruption or noninterruption, which occurs as a conseqence of the feed level in the bin. Both sensor components are mounted opposite each other so as to extend inwardly for a minimum distance from the interior of the bin walls.

Abstract: A hog feeder is disclosed including an annular trough having an upstanding center member with a horizontal top surface. A vertical post extends upwardly and rotatably supports a tapered hopper having a discharge opening located above the plateau. A plurality of radial arms carried by a polygonal plate rotate between the plateau and hopper, the arms including outer ends engageable by hogs' snouts. A removable link interconnects these arms to the hopper. The hopper is vertically adjustable to control the feed rate. A watering system is also disclosed.

Abstract: An inhalation tower comprises two columns forming two concentric ducts each made up of segments fitted into one another. The segments forming the outer duct have an external annular portion at one end and an internal annular portion at the other end, the axial height of the latter being less than the height of the external annular portion, so as to leave a space for receiving a plate. The internal duct has radial connecting ducts which open into the end of a cylindrical cavity formed in the external segment, a space being reserved between the connecting duct and the diameter of an opening through the end of the cavity. The cavity is adapted to receive an inhalation chamber borne by the tray.
