The specification discloses a machine device (10) driven by an inline electric motor (15) to reciprocate a cutting blade (12) when removal of a glass or similar panel is required from a surrounding mount structure, the machine device (10) includes an actuating mechanism having a first input shaft (22) rotatably driven about an input axis (23) by the electric motor (15), a second output member (24) including a connection (42) for a cutting blade (12) restrained for reciprocation along a second output axis (25), a first swivel connection (32) eccentrically disposed laterally from the input axis (23), a second swivel connection (31) having its swivel or pivot point on said second output axis (25), and a connector (26) connecting the first and second swivel connections (32, 31).
A drive arrangement for converting rotary drive motion into reciprocating motion, said drive arrangement including a first member mounted for rotation about a first axis, a second member axially spaced from said first member mounted for reciprocation along a second axis disposed coincident with or parallel to said first axis, a connecting member connected to said first member by first swivel connection means and to said second member by second swivel connection means whereby upon rotation of said first member about said first axis a line connecting said first and said second swivel connection means cycles between a position being in line with said second axis and at least one position forming an acute angle with said second axis.
A drive arrangement for converting rotary drive motion into reciprocating motion, said drive arrangement including a first member mounted for rotation about a first axis, a second member axially spaced from said first member mounted for reciprocation along a second axis, a connecting member connected to said first member by first swivel connection means and to said second member by second swivel connection means, the first swivel connection means being disposed laterally spaced from said first axis.
