Abstract
Abstract An electromagnetically reciprocating motor assembled in a housing, and including an electrical circuit having normally open contacts, and arm mounted in the housing and actuable to close said contacts, a magnetically permeable core, a spring yieldably urging said core in travel to actuate said arm to close said contacts, a solenoid, effective when energized to counter said spring and reverse the travel of said core to open said contacts; said contacts being assembled in and projecting from a plug, the housing having a socket to removably receive said plug to facilitate replacement of worn contacts, and a closure adapted to enclose both plug and socket to resist introduction of moisture and dirt into said housing; one said contact having a flat face, and the other contact having an arcuate face, to effect a rocking, wiping, cleansing action upon closing of the contacts.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A reciprocating, electromagnetic motor including a housing having a bottom wall and a continuous side wall, said housing containing a solenoid, an electrical circuit to energize said solenoid, said electrical circuit having a pair of contacts tensioned to have a normally open position, and having a closed position, to close said circuit, yieldably resistant means urging said contacts to said closed position, said yieldably resistant means yielding to energization of said solenoid to allow said contacts to open, a plug member, assembling said contacts to removably plug into said housing in an operative position, and a socket formed in the housing wall to removably receive said plug.
Claim 2
Dependent Claim
107 words
A reciprocating, electromagnetic motor including a housing having a bottom wall and a continuous side wall, said housing containing a solenoid, an electrical circuit to energize said solenoid, said electrical circuit having a pair of contacts tensioned to have a normally open position, and having a closed position, to close said circuit, yieldably resistant means urging said contacts to said closed position, said yieldably resistant means yielding to energization of said solenoid to allow said contacts to open, a plug member, assembling said contacts to removably plug into said housing in an operative position, and a socket formed in the housing wall to removably receive said plug.
Claim 3
Dependent Claim
68 words
A reciprocating electromagnetic motor as set forth in claim 1, a magnetically permeable core movable by said yieldably resistant means to close said contacts, and responsive, when said solenoid is energized, to overcome said yieldably resistant means and allow said contacts to assume said normally open position, and an annular, magnetically permeable disc, rigidly carried by said core and disposed thereon to intensify said response to said energization.
Claim 4
Dependent Claim
65 words
A reciprocating electromagnetic motor as set forth in claim 1, a boss projecting from said side wall, said socket being formed in said boss, and having a bottom surface, a hole extending through said bottom surface to communicate with the interior of said housing, a closure removably received on said boss, and one of said contacts protruding exteriorly through said closure to receive electrical current.
Claim 5
Dependent Claim
90 words
A reciprocating electromagnetic motor as set forth in claim 1, said pair of contacts being respectively mounted on electrically conductive elongated arms, one arm being tensioned to establish said normally open position, a magnetically permeable core movable by said yieldably resistant means to close said contacts, a circuit closing device Actuated by said core to engage said one arm with a force predetermined to flex said arm after said contacts are closed, whereby a rubbing action is effected between said contacts to effect a self-cleaning, mutual wiping of said contacts.
Claim 6
Dependent Claim
58 words
A reciprocating electromagnetic motor as set forth in claim 4, one of said contacts having a flat contact face, the remaining contact having an arcuate face, whereby the flexing of said elongated arm causes a slight, arcuate, rocking travel of said arcuately formed contact upon the flat face of the opposite contact to effect said mutual wiping action.
Claim 7
Dependent Claim
65 words
A reciprocating electromagnetic motor as set forth in claim 2, a boss projecting from said side wall, said socket being formed in said boss, and having a bottom surface, a hole extending through said bottom surface to communicate with the interior of the housing, a closure removably received on said boss, and one of said contacts protruding exteriorly through said closure to receive electrical current.
Claim 8
Dependent Claim
84 words
A reciprocating electromagnetic motor as set forth in claim 3, said pair of said elongated arms, one arm being tensioned to establish said normally open position, a magnetically permeable core movable by said yieldably resistant means to close said contacts, a circuit closing device actuated by said core to engage said one arm with a force predetermined to flex said arm after said contacts are closed, whereby a rubbing action is effected between said contacts to effect a self-cleaning, mutual wiping of said contacts.
Claim 9
Dependent Claim
58 words
A reciprocating electromagnetic motor as set forth in claim 7, one of said contacts having a flat contact face, the remaining contact having an arcuate face, whereby the flexing of said elongated arm causes a slight, arcuate, rocking travel of said arcuately formed contact upon the flat face of the opposite contact to effect said mutual wiping action.
