IMPROVED MOUSE-TRAP
Three snap traps on a disc; the invention is the rim.
A circular wooden cover holds three spring-loaded snap traps, one in each of three orifices. The springs operate in the usual manner. An annular tin rim is sunk into a groove around the lower edge of the cover and secured with rivets, and metal partitions are driven into the underside to separate the orifices. The rim prevents the wooden cover from cracking.
“I am well aware that traps have been employed with metal rims, but not in a circular form, nor attached in the same manner. I do not, therefore, claim, broadly, the idea of employing a metal band in mouse-traps.”— Anthony G. Davis, from the specification
And the world did not beat a path to his door.
