Abstract: A one way gate primarily for pigs is located between a pair of parallel panels to be mounted in a fence line and includes two gate portions each defined by a transverse rail across the passage between the panels at a height above the passage and a plurality of fingers hanging from the rail separately pivotal in one direction only to the animal to pass and prevented from rotation in the opposite direction. The distance between the gate portions is less than 3.0 feet so as to be less than the length of the animal to prevent an animal being located between the rails and greater than 0.5 feet such that an animal attempting to lift the second fingers cannot simultaneously lift the first fingers.

Abstract: Gestating sows are housed in a series of gestation stalls arranged in a row and backing onto an open alley along a rear of the row of stalls into which the sow can enter by backing out of the stall. A common trough extends along the front of the stalls and is fastened to the floor by fasteners which connect trough sections end to end. The common trough provides a support for the front end of the side walls defining the stalls. A rear gate closes the rear of each stall and connects to a front gate of the stall operable to close the rear gate by the sow as it moves in the stall toward the front. The rear gate latches closed to prevent entry of another sow but is releasable by rear pressure on the rear gate from the sow backing out.

Abstract: An animal feeder includes a hopper above a shelf onto which feed can fall to be taken by the animal or dropped into a trough below the shelf. The height of the shelf is adjustable in a course movement to move the shelf from a low height for smaller animals to a raised height for the animal after they have grown. The shelf is also adjustable in fine movement to change the width of the opening through which the feed passes to control feed rate. The shelf is carried on straps which extend along the end walls of the hopper and are movable by an adjustment linkage defined by a plate carried on the end wall and a manually adjustable lever mounted for pivotal movement on the plate. The lever has two pivot positions on the plate providing the two course adjustments and two graduated scales for the fine adjustment each cooperating with a respective pivot position.

Abstract: A feeder for feeding animals at the weanling stage has a trough with two opposed outwardly inclined front walls over which the animals can reach for taking feed from the trough and a feed hopper for discharging feed downwardly onto a shelf above the trough. Water is supplied into the trough so that the animals may take the feed dry on the shelf or wet from the trough. Water is normally supplied through a first water supply line which has a series of nipples controlled by the animals. However, while the weanlings are very young the first water supply line is closed off and water is supplied from a second supply line which is managed by a timer and water level sensor.

Abstract: An adjustable water supply pipe has a pair of bite nozzles at a bottom end and a wall bracket holding the pipe vertical but allowing the height of the pipe to be adjusted. The bracket has a wall plate with top and bottom plates bent outwardly to define two aligned openings for the pipe. The top plate has a slot which holds the pipe fixed in the upstanding position but with a mouth at one side to release the pipe to an inclined position. The bottom plate is inclined to the horizontal such that the upstanding pipe is jammed against sides of the opening and such that the inclined pipe is free to slide longitudinally. The top plate includes fingers which cooperate with a locking ring on the pipe to hold the pipe upright and the slot is shaped to hold a non-circular portion of the pipe against rotation.

Abstract: A weigh scale and a sorter unit mounted at a front gate for guiding the animal after weighing when the animal emerges from the front gate is transported from pen to pen within a barn on ground wheels with the sorter unit being mounted so as to be movable from a deployed position to a retracted transport position by folding or sliding, in which a total length of the weigh scale and sorter unit is reduced relative to a total length thereof in the deployed position for maneuvering the weigh scale with sorter unit attached during transportation.

Abstract: A two sided feeder for feeding animals as they grow from a first smaller size to a larger size includes a trough with a shelf mounted above the base of the trough with a feed hopper positioned for depositing feed onto the shelf and a water pipe formed from a rectangular tube and extending along the trough at a position underneath the shelf with a plurality of water nipples at spaced positions along the water pipe. A plurality of divider members are clamped on the pipe each between two of the water nipples such that the divider members together act to separate one side of the trough from the other side to prevent the passage therebetween of the animals when at the smaller size.

Abstract: A decorative lawn ornament for supporting an object, such as a rain gauge, comprises an assembly featuring a decorative member, a support device and a support mechanism. The decorative member comprises a metal plate shaped to have visual appeal having a hole therein for mounting on the support device. The support device features a receiving portion for supporting the object, a mounting portion for detachably engaging the plate and a reinforcing portion for supporting said receiving portion on said mounting portion. The mounting portion features a groove in the top surface of a protruding member which extends from one side of the plate to the other through the hole. To mount the plate on the support device, the top edge of the hole in the plate fits within the groove and the bottom edge of the hole slides over the bottom surface of the protruding member and snaps into place.

Abstract: In a hog production plant the hogs are divided into a series of separate pens within the hog plant based generally on weight such that the lightest hogs closest to the initial weight are arranged in the first pen when the arrive and the heaviest hogs closest to the final market weight are arranged in the last pen. Each pen includes a sorting scale arranged to receive a hog therein and to weigh the hog for selection of one of two outlet paths leading to the next pen of the series or, in respect of the last pen, to a discharge location.

Abstract: A farrowing crate is defined by a cage having a main central flooring section for the sow and two side sections for the piglets. A feeder is located at the front wall for supplying feed to the sow when standing and includes a hopper mounted on a front gate outside the crate for and a trough for receiving feed discharged from the hopper. The trough is formed by a base plate lying substantially flat on the flooring from the hopper rearwardly to a raised transverse restricting member to restrict the escape of feed formed by an inverted V-shaped rib formed in the base plate spaced from the front wall and extending generally across the base plate to define a trough area of a height which allows the sow to lie with its neck and head over the restricting member without discomfort. The gate panel includes guards each side of the opening to restrict side to side movement of the sow's head. The trough is restricted by sides at the sides of the sow flooring.

Abstract: An animal feeder includes a hopper above a shelf onto which feed can fall to be taken by the animal or dropped into a trough below the shelf. The height of the shelf is adjustable to change the width of the opening through which the feed passes to control feed rate. The shelf is carried on straps which extend along the end walls of the hopper and are movable by an adjustment linkage defined by a plate carried on the end wall and a manually adjustable lever mounted for pivotal movement on the plate.
