Abstract
Abstract A suction type bug catcher and ejector comprising a manually operated piston in a cylinder having a bug confining cell which holds bugs captive that are caught with the air drawn into the cylinder by the inward movement of the piston. An air vent is provided to exhaust the air from the cylinder and bug confining cell when moving the piston outwardly to reset it for a subsequent suction stroke. The bugs captured are ejected from the confining cell when the piston is moved forcefully outward while the vent is closed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
A suction type bug catcher and ejector comprising a hollow cylindrical body member having a cap at one end and is open at the opposite end and a bug confining cell therein consisting of a self-closing gate which opens to a forceful flow of air, and a screen barrier; a piston arranged to be manually reciprocated within the body member by a piston rod slidably mounted in the cap, to cause a forceful flow of air inwardly or outwardly of the body member through the said open end and self-closing gate and confining cell, in response to a like movement of the piston; and an air vent extending from the body member ahead of the piston throughout the length of the piston rod, a vent opening at the end of the piston rod oppositE of the piston, arranged to be covered or uncovered to change the directional flow of air from the body member when the piston is moved toward the open end of the body member.
Claim 2
Dependent Claim
167 words
A suction type bug catcher and ejector comprising a hollow cylindrical body member having a cap at one end and is open at the opposite end and a bug confining cell therein consisting of a self-closing gate which opens to a forceful flow of air, and a screen barrier; a piston arranged to be manually reciprocated within the body member by a piston rod slidably mounted in the cap, to cause a forceful flow of air inwardly or outwardly of the body member through the said open end and self-closing gate and confining cell, in response to a like movement of the piston; and an air vent extending from the body member ahead of the piston throughout the length of the piston rod, a vent opening at the end of the piston rod oppositE of the piston, arranged to be covered or uncovered to change the directional flow of air from the body member when the piston is moved toward the open end of the body member.
Claim 3
Dependent Claim
131 words
A suction type bug catcher and ejector comprising a hollow cylindrical body member having a cap at one end and is open at the opposite end and a bug confining cell therein consisting of a self-closing gate which opens to a forceful flow of air, and a screen barrier; a piston arranged to be manually reciprocated within the body member by a piston rod slidably mounted in the cap, to cause a forceful flow of air inwardly or outwardly of the body member through the said open end and self-closing gate and confining cell in response to a like movement of the piston; the rim of the said open end of the body member having recessed portions to allow the inflow of air when the said open end has been blocked.
