Abstract

Abstract A dry cell magazine with a movable contact plate elastically urging a dry cell against a fixed contact in order to securely hold the dry cell between the two contacts. A seesaw lever is mounted adjacent the movable contact plate for restraining the contact plate in an open position. The dry cell magazine has a cover member which engages an operation plate when the cover member is closed on the dry cell magazine. The cover member, operation plate, seesaw lever and movable contact plate are cooperatively arranged in such a manner that upon shifting the operation plate in one direction, the cover member is released from the operation plate and swings up and the movable contact plate is moved until it is retained by the seesaw lever.

Claim 2
Dependent Claim 80 words
A DRY CELL MAGAZINE COMPRISING: A CASING FOR RECEIPT OF SAID DRY CELL: A COVER MEMBER MOVABLY MOUNTED WITHIN SAID CASING: A MOVABLE CONTACT PLATE FOR ENGAGEMENT WITH SAID DRY CELL: AND MEANS FOR RETRACTING SAID CONTACT PLATE FROM SAID ENGAGEMENT WITH SAID DRY CELL AND FOR OPENING SAID COVER MEMBER, SAID COVER MEMBER HAS ONE EDGE HVING AN ARRESTING GROOVE WHICH IS IN CONTACT WITH SAID RETRACTING AND OPENING MEANS WHEN SAID COVER MEMBER IS IN A COLOSED POSITION
Claim 3
Dependent Claim 99 words
A dry cell magazine comprising: a casing for receipt of said dry cell; a cover member movably mounted within said casing; a movable contact plate for engagement with said dry cell; and a sliding operation plate having one edge in contact with said cover member and a second edge in contact with said contact plate, said cover member moving out of contact with said operation plate and said second edge of said operation plate moving said contact plate when said operation plate is moved in one direction, said operation plate being spring-biased in a direction opposite said one direction.
Claim 4
Dependent Claim 99 words
A dry cell magazine comprising: a casing for receipt of said dry cell; a cover member movably mounted within said casing; a movable contact plate for engagement with said dry cell; and a sliding operation plate having one edge in contact with said cover member and a second edge in contact with said contact plate, said cover member moving out of contact with said operation plate and said second edge of said operation plate moving said contact plate when said operation plate is moved in one direction, said operation plate being spring-biased in a direction opposite said one direction.
Claim 5
Dependent Claim 122 words
A dry cell magazine comprising: a casing for receipt of said dry cell; a cover member movably mounted within said casing; a movable contact plate for engagement with said dry cell; means for retracting said contact plate from said engagement with said dry cell and for opening said cover member; and a seesaw lever having a first end acting in response to said retracting and opening means and a second end adjacent said contact plate, said second end contacting and retaining said contact plate when said first end is retracted by said retracting and opening means, said seesaw lever releasing said contact plate for engagement with said dry cell when said cover member is placed in a closed position on said casing.
Claim 6
Dependent Claim 122 words
A dry cell magazine comprising: a casing for receipt of said dry cell; a cover member movably mounted within said casing; a movable contact plate for engagement with said dry cell; means for retracting said contact plate from said engagement with said dry cell and for opening said cover member; and a seesaw lever having a first end acting in response to said retracting and opening means and a second end adjacent said contact plate, said second end contacting and retaining said contact plate when said first end is retracted by said retracting and opening means, said seesaw lever releasing said contact plate for engagement with said dry cell when said cover member is placed in a closed position on said casing.
Claim 7
Dependent Claim 104 words
A dry cell magazine for use with an apparatus having a casing, said dry cell magazine comprising: a pair of contacts mounted within said casing for engagement with said dry cell; a movable contact plate mounted within said casing, one of said pair of contacts being connected to said contact plate; a cover member movably mounted on said casing; a slidable operation plate engaging said cover member when said cover plate is in a closed position on said casing; and means for retaining said movable contact plate out of engagement with said dry cell, said retaining means operating in response to said operation plate.
Claim 8
Dependent Claim 104 words
A dry cell magazine for use with an apparatus having a casing, said dry cell magazine comprising: a pair of contacts mounted within said casing for engagement with said dry cell; a movable contact plate mounted within said casing, one of said pair of contacts being connected to said contact plate; a cover member movably mounted on said casing; a slidable operation plate engaging said cover member when said cover plate is in a closed position on said casing; and means for retaining said movable contact plate out of engagement with said dry cell, said retaining means operating in response to said operation plate.
Claim 9
Dependent Claim 209 words
A dry cell magazine comprising: a casing for receipt of a dry cell; a fixed contact mounted in said casing; said fixed contact receiving one end of said dry cell; a movable contact plate mounted in said casing adjacent the other end of said dry cell, said contact plate biased against said other end of said dry cell for holding said one end of said dry cell against said fixed contact; a cover member movably mounted on said casiNg and biased to pivot to an open position; a seesaw lever mounted in said casing adjacent said movable contact plate; and an operation plate slidably mounted adjacent said cover member, said operation plate engaging said cover member when said cover member is in a closed position, said operation plate, said cover member, said seesaw lever and said movable contact plate being cooperatively arranged, so that shifting of said operation plate in one direction when said cover plate is in said closed position results in said cover member moving to said open position and results in said contact plate moving away from said other end of said dry cell, said cover member causing said seesaw lever to retain said movable contact plate away from said other end of said dry cell.
Claim 10
Dependent Claim 209 words
A dry cell magazine comprising: a casing for receipt of a dry cell; a fixed contact mounted in said casing; said fixed contact receiving one end of said dry cell; a movable contact plate mounted in said casing adjacent the other end of said dry cell, said contact plate biased against said other end of said dry cell for holding said one end of said dry cell against said fixed contact; a cover member movably mounted on said casiNg and biased to pivot to an open position; a seesaw lever mounted in said casing adjacent said movable contact plate; and an operation plate slidably mounted adjacent said cover member, said operation plate engaging said cover member when said cover member is in a closed position, said operation plate, said cover member, said seesaw lever and said movable contact plate being cooperatively arranged, so that shifting of said operation plate in one direction when said cover plate is in said closed position results in said cover member moving to said open position and results in said contact plate moving away from said other end of said dry cell, said cover member causing said seesaw lever to retain said movable contact plate away from said other end of said dry cell.
Claim 11
Dependent Claim 98 words
A dry cell magazine as defined in claim 5 additionally comprises a cell case for receipt of said dry cell and pivotally mounted within said casing, said cell case having a dry cell operating position and a dry cell removal position, said cell case cooperatively arranged with said operation plate, said cover member, said seesaw lever, and said movable contact plate, said cell case pivoting to said removal position in response to said shifting of said operation plate, said cell case moving to said operating position in response to said cover member being moved to said closed position.
