To all whom it may concern:
Be it known that I, Otto Kampfe, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented an Improvement in Traps for Animals, of which the following is a specification.
My invention relates to a trap of peculiar form and construction for catching small animals such as Rodentia Myomorpha, and especially rats and mice of all kinds.
In connection with the form of traps heretofore employed for catching small animals such as rats and mice, many people object to the proximity of the animal when dead in the trap, also to being obliged to handle the animal to remove the same from the trap, and if a trap is wet, as would be necessary in drowning an animal therein, either the trap is injured by being wet or when dry becomes rusty and unsightly, and thereafter soils the hands in further use. There are also other and perhaps numerous objections to the well known forms of traps.
In carrying out my invention, I preferably employ a glass jar as the main portion of the trap and in connection with an apertured closing end or removable cover therefor, I employ two arms, an arched member and bait carrying bar pivoted to the arms. A pivoted spring actuated apertured closing disk is connected to the closing end or removable cover and this latter is held open projecting into the jar by being caught on a ledge of the arched member. I may employ a convex or flat bottom to the jar and silver the same so as to simulate a mirror, or arrange the bottom to receive a mirror, in which the animal surveying and about to enter the trap, sees itself in the reflecting surface and believing that another animal is also after the bait, hastens its determination to seize the bait, which act immediately springs the trap and releases the closing disk, which at once goes to its seat, closing the aperture in the end or cover and imprisoning the animal in the trap. An aperture made in this closing disk is filled with fine wire gauze permitting the entrance of air to the animal in the jar and the entrance of water either under a faucet or when the entire trap is immersed in a pail of water to drown the animal, the removable parts permitting the dead animal to be dropped out of the trap. The glass vessel is easily cleansed and the metal parts preferably being galvanized, do not become rusty or unsightly in use.

In the form of my invention shown in
The full lines in
When the animal enters the trap and grasps the bait or nibbles at the same, this shifts the bait bar
The device is simple in construction, readily cleansed and kept clean; it is more permanent and lasting than a wooden trap, and more humane in its functions. If the base of the jar or vessel is formed with a mirror, as I prefer, the trap is more effective in its operation.
I claim as my invention:
1. An animal trap comprising a body, a removable apertured cover, a spring actuated disk hinged to swing into the said trap body, arms also projecting into the body or vessel both removable with the cover, and pivoted devices carrying the bait supported by said arms and adapted to be held in an operative position by the spring action of said disk when the trap is set.
2. An animal trap comprising a body, a removable apertured cover, a spring actuated disk hinged to swing into the said trap body, arms also projecting into the body or vessel, an arch bar pivoted to said arms, a bait bar and a shoulder connected therewith, the bait bar carrying the bait on its free end and the shoulder serving to receive the free end of said disk.
3. An animal trap comprising a body, a removable apertured cover, a spring actuated disk having an aperture filled with fine wire gauze hinged to swing into the said trap body, arms also projecting into the body or vessel and pivoted devices supported thereby and carrying the bait at one end and adapted to be held in an operative position at the other end by the spring action of the said disk when the trap is set.
4. An animal trap comprising a body, a removable apertured cover, a spring actuated disk having an aperture filled with fine wire gauze hinged to swing into the said trap body, arms also projecting into the body or vessel, an arch bar pivoted to said arms, a bait bar and a shoulder connected therewith, the bait bar carrying the bait on its free end and the shoulder on its opposite end serving to receive the free end of said disk.
5. An animal trap comprising a cylindrical body of transparent material such as glass closed at one end and having a screw threaded neck at the other end, a removable screw threaded cover apertured, a disk closing the aperture in the cover and having a spring actuated hinge and opening inwardly into the body of the transparent vessel, arms projecting into said vessel and devices pivotally connected to said arms and adapted to support the bait at one end and to be held at the opposite end in a set position by the free edge of said disk under the tension of the spring hinge.
6. An animal trap comprising a cylindrical body of transparent material such as glass closed at one end and having a screw threaded neck at the other end, a removable screw threaded cover apertured, a disk closing the aperture in the cover and having a spring actuated hinge and opening inwardly into the body portion of the transparent vessel, arms projecting into said vessel, an arch bar pivoted to the free ends of the arms, a bait bar and shoulder connected to the arch bar, the bait bar at its free end adapted to carry the bait and the shoulder to receive the free edge of the disk and the parts to be held as set by the spring action of the hinge of the disk.
7. An animal trap comprising a cylindrical body of transparent material such as glass, having a concavo-convex end silvered to simulate a mirror, and having a screw threaded neck at the other end, a removable screw threaded cover apertured, a disk closing the aperture in the cover and having a spring actuated hinge and opening inwardly into the body of the transparent vessel, arms projecting into said vessel and devices pivotally connected to said arms and adapted to support the bait at one end and to be held in a set position at the other end by the free edge of said disk under the tension of the spring hinge.
8. An animal trap comprising a cylindrical body of transparent material such as glass, having a concavo-convex end silvered to simulate a mirror and having a screw threaded neck at the other end, a removable screw threaded cover apertured, a disk closing the aperture in the cover and having a spring actuated hinge and opening inwardly into the body of the transparent vessel, arms projecting into said vessel, an arch bar pivoted to the free ends of the arms, a bait bar and shoulder connected to the arch bar, the bait bar at its free end adapted to carry the bait and the shoulder to receive the free edge of the disk and the parts to be held as set by the spring action of the hinge of the disk.
9. An animal trap comprising a body, a removable apertured cover, a spring actuated disk hinged to the inner surface of the cover, arms connected to the cover and projecting into the body or vessel, and pivoted devices supported by the arms and carrying the bait and adapted to be held in an operative position by the spring action of said disk when the trap is set.
10. An animal trap comprising a body, a removable apertured cover, a part coming between the cover and the end or the body to which the cover is secured and apertured to correspond with the cover, a spring hinge actuated disk opening into the body, arms projecting into the body or vessel and devices pivoted to the arms and carrying the bait and adapted to be held in an operative position by the spring action of the disk, when the trap is set.
