发明名称 Timer system for a cage
摘要 A cage for trapping an animal having a timing system for indicating the time that the animal was trapped in an enclosure. The cage is defined by a housing having an opening therein with a door which is opened to allow an animal to enter the housing. A closure arrangement responds to the animal passing through the opening for closing the door to trap the animal in the housing. A clock, having a second hand, minute hand, hour hand and an indicator hand that move with respect to a dial face, is secured to the housing. A lever responsive to the closure of the door activates a switch to stop the clock and provide an indication of the time that the door was closed by the location of the hour hand and indicator hand. If the indicator hand is located on the left hand side of the hour hand an animal was trapped within the first twelve hours after the trap was set and if the indicator hand is on the right hand side of the hour hand the animal was trapped more than twelve hours after the trap was set.
