Animal feeder

Abstract

A feeder for a horse or another animal includes a container with an open top end and a closed bottom end, a lid for closing the top end, a bottom opening proximate the lower end of at least one of a front and rear wall of the container, a gate normally closing the opening, a cable connecting the top of the gate to a winch, and a control assembly for periodically operating the winch to wind or unwind the cable on the winch to open the gate at predetermined times during the day permitting access to the feed, and for closing the gate after preselected intervals to prevent further access to the feed.

Claims

1. An animal feeder comprising a stand; a container mounted on the stand, the container including a front wall, a rear wall, a pair of opposed side walls, a top opening, a closed bottom end and a lid on the top opening for protecting feed in the container from the elements; a bottom opening proximate a lower end of at least one of said front and rear walls; a gate normally closing said bottom opening; a cable having a first end attached to a top end of the gate; a winch carrying a second end of the cable; and a control assembly for periodically operating the winch to wind or unwind the cable on the winch to open the gate at predetermined times permitting access to the feed, and for closing the gate after preselected intervals to prevent further access to the feed.

2.

DETAILED DESCRIPTION OF THE INVENTION

[0011] In the following detailed description, the feeder is referred to as a horse feeder. However, depending upon the feed, the feeder can be used to dispense feed to other animals.

[0012] With reference to FIGS. 1 to 5, the basic elements of a horse feeder in accordance with the invention are a stand carrying an elongated, rectangular cross section container which are indicated generally at 1 and 2, respectively.

[0013] The stand 1 is made of aluminum tubes and includes a pair of elongated, spaced apart, parallel feet 3 interconnected by a pair of crossbars 4. A post 5 extends vertically upwardly from the center of each foot 3. The posts 5 are maintained in vertical positions by diagonal braces 6.

[0014] The container 2 is pivotally mounted between the posts 5 on stub axles 7, which extend from crossbars 8 on the sides 10 and 11 of the container 2. The container 2 can be rotated between the vertical, use or feeding position shown in FIGS. 1 to 5 and a horizontal, feed loading position shown in phantom outline in FIG. 3. Movement beyond the feeding and feed loading position is prevented by a pair of L-shaped stops 12 and 13. The vertical limiting stops 12 are mounted on second crossbars 14 on the sides 10 and 11 of the container 2. When the container 2 is in the vertical, feeding position, the outwardly extending arms of the stops 12 bear against the posts 5, preventing rotation of the container beyond the vertical in one direction. When the container 2 is rotated to the horizontal position (counterclockwise in FIGS. 1 and 4, clockwise in FIG. 5), the outwardly extending arms of the stops 13 bear against the posts 6, preventing rotation of the container 2 beyond the horizontal loading position. The container is releasably retained in the vertical, use position or the horizontal, loading position by a pin 15 (FIG. 6), which is inserted through aligned holes (not shown) in an arm of one of the stops 12 or 13 and in one post 5. A handle in the form of a ring 16 (FIG. 6) is provided on the outer end of the pin 15 for facilitating insertion and removal of the pin. Feed, in the form of bales of hay (not shown), is loaded into the container 2 via the open top end of the container which is covered by a lid 17.

[0015] The feed is discharged from the container through openings 18 in both the front and rear walls 19 and 20, respectively. Of course, a single opening 18 can be provided in the front or rear wall for feeding a single animal. The openings 18 are normally blocked by gates 21 and 22 on the front and rear of the container 2. The gates 21 and 22 are slidably mounted in tracks 24 connected to the bottom corners of the container 2. The gates 21 and 22 have inverted V-shaped upper ends 25. Cables 27 and 28 extend upwardly from the apexes 29 and 30 of the upper ends of the gates 21 and 22, respectively, to a winch 31. The cable 27 extends directly upwardly to a bottom drum 32 in the winch 31. The cable 28 extends upwardly from the gate 22 around pulleys 33 and 34 mounted in brackets 36 and 37 at the upper ends of the rear and front walls 20 and 19, respectively to a top drum 39 in the winch 31. Discs 40 and 41 are mounted on the drums 32 and 39 for centering the cables 27 and 28 in the winch 31.

[0016] As best shown in FIG. 7, the winch 31 also includes a generally U-shaped housing with holes 43 in a rear wall 44 for mounting the winch on the front wall 19 of the container 2. A toothed wheel 45 is mounted on the drum 32 inside of a side wall 47 of the winch housing. The drum 32, which is defined by a shaft extends through the side wall 47 of the housing into a control assembly which includes a box mounted on the front wall 19 of the container 2. The box 48 containing a reversible motor 49 (FIG. 2) connected to the outer end of the winch drum 32 for rotating the latter. A second toothed wheel 50 is mounted on one end of the upper drum 39 and meshes with the lower toothed wheel 45. While the drum 32 and the toothed wheel 45 rotate in one direction, the drum 39 and the toothed wheel 50 rotate in the opposite direction, whereby the gates 22 and 23 are simultaneously raised or lowered. The toothed wheels 33 and 39 can be releasably locked in one position by an optional pawl 52 pivotally mounted on a pin 53 extending through the side wall 47 of the side wall 47 of the winch housing for engaging the teeth on the wheel 45.

[0017] As well as the motor 49, the control box 48 contains batteries (not shown) for providing electrical power to the motor and a microprocessor 54 (FIG. 2) for controlling operation of the motor. A solar panel 55 is mounted on the front wall 19 of the container 2. A wire 56 extends between the panel 55 and the batteries in the box 48 for charging the batteries. The microprocessor is programmed so that at predetermined timed intervals during the day, the gates 21 and 22 are opened, permitting access to the feed through the openings 18 in the front and rear walls 19 and 20 of the container 2.

[0018] When loading feed into the container 2, the lid 17 is removed from the top of the container 2. Bales of hay are loaded into the container 2 by turning them sideways. The height of the posts 5 is such that when the container 2 is rotated to the loading position (shown in phantom outline in FIG. 5), the open top end of the container is at the height of a tailgate of a pick-up truck which reduces the amount of lifting required during loading. The container 2 can be loaded with enough bales of hay to provide feed for several days before it becomes necessary to load more feed. The lid 17 is replaced on the open top end of the container 2 and the container is returned to the vertical, feeding position shown in FIGS. 1 to 5, permitting gravity to move the feed toward the bottom of the container.

[0019] The microprocessor 54 is programed to operate the motor 49 at predetermined times to fully open the gates 21 and 22. After a preselected interval, the motor 29 is operated in reverse to close the gates 21 and 22. The microprocessor 54 can be programed to open and close the gates 21 and 22 any number of times and for any intervals during the day.
