Application filed June 4,

My invention relates to trap nests for hens.

The object of my invention is to provide it nest into which it hen can enter from one side but can not leave ire-m the other side until she lays an egg, the respective doors being operated by the weight of the hen and controlled by the My invention is more fully described in the accompanying specification and drawing in which- Fig. 1 is an elevation of from the exit side, F193. 2 isu sectional elevutiou of some, Fig. 3 is an elevation viewed from the entrance side, Fig. l is an elevation of the nest viewed from the exit side with the trap door open, Fig. :3 in a sectional elevat on with the nest lowered, F5 6 is an elevation viewed from the entrs e side with the trap door closed, Fig. 7 is en elevation showing at shade over the entrance, Fig. 8 is a sectional plan view, l igs. 9 and 10 are details showing the construction of hinges, Figs. 11 and 12 are detailed views of at the corners of the nest box, and Fig. 13 is an elevation showing arrangement of several trap nests with s common conveyor.

My trap nest consists of shousiug 1 provided on one side with an entrance aperture end on the other side with an exit aperture V A nest board is placed inside of the housing and is hinged with hinges 5 to the front wall of the housing (at the entrsnce side). The other end of the nest board rests on 1% block 6 by means of 21 supporting board 7 which is hinged to the lower side of the nest board l. The nest bosrd l provided with e circular depression 8 forming a nest for a hen.

At the bottom oft-his depression there is an aperture communicating with an inclined trough or spout 9 which is directed with its opening against the sup- 7. This trough forms u which may strike the sup porting boerd T in its iuovei 11' thereby knocking this supporting board oil the rest block 6. The side of the board 7 is provided with acushion 10, also it cushion 11 is placed on top of the block 6.

The rear end of the nest board l is connected by means of a link 12 with n arm which is rotetively mounted on 3. pin 14 with its central portion. The front end of the gr n 13 is connected by means of a link porti u 51' b05111 l slide tor :m c"

with e board 16. One end of this board is notatively mounted on 2!. pin 17. The link 15 is connected near the pin 17 so that the freeend of this board 16 tends to hang down, .oyerbahincing and lifting the nest board 4 through links 12 and 1' end the arm 13. In this position the board is hidden below the lower edge of the entrance sperture 3 and does not obstructthe entrance for the hen.

The rear end of the nest bom d l is connected by means of it link 17 with a board 18 rotetively mounted on pin 19. The link 17 is connected near the point of suspension so that the weight of the heard, through the link 17, tends ,to .oyerbulnnce the weight of the nest board 4:, raising some to its normal operating position as shown in Figs. 1, 2 and 3. In this position the board 18 hangs against the exit aperture .3, closing some to the hen.

As can be seen from the above, the boards 16 and 18, with their combined weight, tend to support the nest board l in its upper or operating position, leaving the entrance eoerture open and the exit closed.

The bottom 20 of the housing is placed at an angle so that the egg can roll outside through an aperture 21 into it box 22 or on a belt conveyor 23.

A number of such nests may be placed in a row as shown in Fig. 13 and connected with a belt conveyor 23 which may .be operated iii-anuo l ly when required iby'means of e. handwheel 24- end a. belt 25.

A shade or shield 26 may be attached to the well of the housing on the outside order to protect the nest from the rain and from thesuirs rays.

Figs. 9 and 10 illustrate the preferred method of melting hinges for the nest hoard 4. For this purpose eye screws 2? are used with rods or wires 28. The corners of the housine or box 1 may be connected by means screws 30 to one board and hooked under a. E -bolt $1 attached to the other board.

The operation of my trap nest is as follows. I

The nest board 4 is normally kept in its upper p QSl-idO n by the weight of the closing boards 16 and 18 and is supported by the swinging or hinged stand board 7. In this position the hen can enter through the open gate 2,. the exit gate 3 bei-ng closed, the hen llO other side of the nest.

must either remain in the nest or return through the front or entrance gate 2. it she lays an egg 32, this egg operates the trap nest as follows: it rolls through the aperture in the trough 9 and strikes the rest board 7, pushing it oil? the supporting block 6. The nest board t, under weight of the hen, settles to its lowest position, raising the gate bars 16 and 18. The gate bar 16 in its raised position closes the entrance gate 2 and the gate bar 18 opens the exit gate 3 allowing the hen to leave from the This enables the henlqeeper to select the hens which are laying eggs from those which are idle.

The rolls on the inclined bottom 20 into a. box 22 with a cover 33. When a number of such nests are placed in a row, as shown in Fig. 13, a belt conveyor 23 may be used for the eggs (see also Fig. This conveyor may be moved from time to time by the handwheel 24-, thereby bringing all the eggs into one place at the end ot the conveyor.

Vhcn the hen leaves the nest, the gate bars 16 and 18 swing down under their own weight, raising the nest board 4t through links 15 and 17 until the rest board 7 rises above the block 6 and swings into an operative position as shown in Fig. 2. The nest is then ready for another hen.

The advantage of my trap nest is that it is entirely automatic in its action and effectively sorts out the laying hens from those which are idle; the removal of the eggs is also accomplished automatically into a box or conveyor outside of the nest.

I claim as my invention:

1. In a trap nest, the combination with a housing of a nest board, the opposite sides of said housing being provided with en trance and exit apertures, boards pivotally supported on the walls of said housing in a cooperative relation to said apertures, links connecting said boards with said nest board, said boards being arranged to stay in the lowered positions, one 01 said boards when in a lowered position being adapted to open said entrance aperture, and the other of said boards when in a lowered position being adapted to close said exit aperture, the weight of said hoards lending to keep said nest board in a raised position. means to lock said nest board in its raised, position, said. locking means being adapted, to be relcased by an egg laid by the hen.

2. In a trap nest, the combination with a housing of a nest board, the opposite sides of said housing being provided with entrance and exit apertures, boards pivotally upported on the walls inside of said housing, said nest board being pivotally connected to the wall of said housing at one end, a link connecting the free end of said nest board with one of said boards, an arm pivotally supported on the "all of said housing, a link connecting one end of said arm with the free end of said est board, a second link connecting the other end of said arm with the other of said boards, said boards being arranged to hang down by their weight and to raise the free end of said nest heard through said link connections, one of said boards when in a lowered position being adapted to open said entrance aperture, and the other of said boards when in a lowered position being adapted to close said exit aperture, a locking support for the free end of said nest board, said support being adapted to be released by the laid by the hen, and means to remove said egg from the inside of said housing.

3. In a trap nest, the combination with a housing of a nest board hinged with one end to the wall of said housing, the other end of said nest board being free, the opposite walls of said housing being provided with entrance and exit apertures, closing boards for said apertures pivotally supported on the walls of said housing, operating connections between said closing boards and the free end of said nest board, the weight of said closing hoards tending to keep said nest board in a raised position, means to lock said nest board in its raised position, said looking means being adapted to be released by the movement of an laid by the hen, one of said closing boards being adapted to open the entrance and the other closing board being adapted to close the exit aperture when said nestboard is in its raised position, the functions of said closing boards being reversed when said nest board is depressed under the weight of said hen.

4. In a trap nest, the combination with a housing of a nest board, the opposite walls of said housin being provided with entrance and exit apertures, closing boards for said apertures pivotally supported on the walls of said housing, operating connections between said closing boards and said nest board, the weight of said closing boards tending to keep said nest board in a raised position, a supporting block pivotally suspended underncath said nestboard and adapted to support said nest board in the raised position, an inclined trough with an aperture at the bottom of said nest board and directed against said supporting block, said supporting block being adapted to he released by the impact of an egg from said trough thereby letting said nest boardv be lowered bythe weight (it a hen, said nest board in its downward movement being adapted through said connections to close the entrance aperture and to open the exitaperture for said hen.
