Pneumatic timing attachment for an electromagnetic device

A timer attachment for an electromagnetically operated device wherein the device includes:

• a housing having a side and a member that is movable in the housing from an at rest position to an operated position in response to an energization of an electromagnet, said attachment comprising:
• a housing part secured to a side of the housing in either of two selected positions, an operator movable along an axis in the housing part, means in the housing part for translating movement of the member to the operator for causing the operator to move from a first position to a second position an adjustable interval after the member is moved from the at rest position to the operated position when the housing part is secured at the side of the housing in one of the two selected positions and for causing the operator to move from the second position to the first position an adjustable interval after the member moves from the operated position to the at rest position when the housing part is secured to the side of the housing in a second of the two selected positions,
• a cover secured on a side of the housing part,
• a slider mounted for movement adjacent a underside surface of the cover, said slider having a pair of spaced advisory legends on a surface that is adjacent the underside of the cover with the distance between the legends equal to a distance between a pair of openings in the cover,
• a pair of oppositely facing inclined surfaces extending toward the side of the housing from an underside surface of the slider,
• and a pair of individually operable plungers extending through the housing part with each of the plungers having a first end engagable with one of the inclined surfaces and a second end engageable with portions of the housing for actuating one of the plungers and moving the slider in a first direction when the housing part is secured to the housing in the first position and actuating a second one of the two plungers and moving the slider in a direction opposite the first direction when the housing part is mounted in the second position.

A timer attachment for an electromagnetically operated device wherein the device includes:

• a housing having a front end and a member that is movable in the housing from an at rest position to an operated position in response to an energization of an electromagnet, said attachment comprising:
• a housing part secured at the front end of the housing in either of two selected positions, an operator movable along an axis in the housing part, means in the housing part for translating movement of the member to the operator for causing the operator to move along an axis from a first position to a second position an adjustable interval after the member moves from the at rest position to the operated position when the housing part is secured at the front end of the housing in one of the two selected positions and for causing the operator to move along the axis from the second position to the first position an adjustable interval after the member moves from the operated position to the at rest position when the housing part is secured at the front end of the housing in a second of the two selected positions,
• a pair of parallel sockets extending axially along and spaced equidistantly on opposite sides of the axis, a pair of switch cartridges inserted into the sockets in either of two positions with the switches having plungers movable by the operator in either of two directions and indicia visible on external surfaces of the cartridges indicating two different modes of contact operation of the cartridges when the cartridges are inserted into the sockets in either of the two positions,
• a cover secured at a front end of the housing part, said cover having openings extending through the cover from a front side of the cover to a rear side of the cover including openings for viewing the indicia,
• a slider mounted for movement adjacent the rear side of the cover, said slider having a pair of spaced advisory legends on a front surface that is adjacent the rear side of the cover with the distance between the legends equal to a distance between a pair of the openings in the cover,
• a pair of oppositely facing inclined surfaces extending rearwardly from a rear surface of the slider,
• a pair of individually operable plungers extending through the housing part with each of the plungers having a first end engagable with one of the inclined surfaces and a second end engageable with portions of the housing for actuating one of the plungers and moving the slider in a first direction when the housing part is secured to the housing in the first position and actuating a second one of the two plungers and moving the slider in a direction opposite the first direction when the housing part is mounted in the second position said inclined surfaces and advisory legends having a position on the slider for exposing one of the legends through an opening in the cover when the slider is positioned by the inclined surfaces at a first position and exposing a second one of the legends when the slider is positioned by the inclined surfaces at a second position, and
• a first pair of slats extending in opposite directions from the slider for obscuring a first pair of openings in the cover and a first pair of indicia when the slider is in the first position and a second pair of slats extending in opposite directions from the slider for obscuring a second pair of openings in the cover and a second pair of indicia.
