Abstract
Abstract A pan having a perforated bottom is within and rests on the bottom of the snail trap container which is inserted into the ground. An upwardly extending handle of the pan carries a cover and supports it above the open top of the container to serve as a rain shield. The handle is hollow and receives a float. A liquid level gauge in the form of a rod is affixed to the float and projects upwardly through the top of the handle.

Total Claims: 7
Claim 1
Independent Claim
188 words
In a snail trap comprising an open-top container having side walls and a bottom defining a space for receiving a liquid, said container being adapted to be inserted into the ground and to receive in said space a liquid which attracts snails, the improvement comprising: a sieve-like, snail collecting device within said container and resting on the bottom thereof, said device having a periphery in juxtaposition to said walls, handle means comprising an upright extending vertically from the center of the device to a level above the top of the container for use in lifting the device out of the container, and includes a cover which projects outwardly beyond said walls and is at an elevation above the top of the container, wherein said upright projects above said cover, and wherein said upright has a hollow interior and a top, means providing fluid communication between the hollow interior and the space within the container, and including a float in said interior and having a stem projecting upwardly beyond the top of the upright to serve as a gauge to indicate the level of the liquid in the container.
Claim 2
Dependent Claim
