Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
110 words
A timing device comprising: a contact assembly; a contact actuator for actuating said contact assembly; an electromagnet for resetting said contact actuator in response to a reset signal; a driven gear containing a cam surface thereon controlling movement of said contact actuator; a motor for driving said driven gear; means for coupling said motor to said driven gear; a molded frame to which said contact assembly, said contact actuator, said electromagnet, said means for coupling and said motor are attached; a housing covering said molded frame; and a base member to which said electromagnet is attached, said molded frame being partially sandwiched and fixed between said base member and electromagnet.
Claim 2
Dependent Claim
110 words
A timing device comprising: a contact assembly; a contact actuator for actuating said contact assembly; an electromagnet for resetting said contact actuator in response to a reset signal; a driven gear containing a cam surface thereon controlling movement of said contact actuator; a motor for driving said driven gear; means for coupling said motor to said driven gear; a molded frame to which said contact assembly, said contact actuator, said electromagnet, said means for coupling and said motor are attached; a housing covering said molded frame; and a base member to which said electromagnet is attached, said molded frame being partially sandwiched and fixed between said base member and electromagnet.
Claim 3
Dependent Claim
22 words
A timing device as in claim 1, wherein said electromagnet is attached to the base member by at least one fastening device.
Claim 4
Dependent Claim
46 words
A timing device as in claim 1, wherein said contact assembly and said electromagnet are attached to said molded frame so that the moving direction of an armature of said electromagnet and the moving direction of the contact blades of said contact assembly are in parallel.
Claim 5
Dependent Claim
45 words
A timing device as in claim 1, wherein the contact assembly is attached to the molded frame so that one side of said contact assembly is located adjacent said base member and the contact blades of said contact assembly extend upwardly from said base member.
Claim 6
Dependent Claim
49 words
A timing device as in claim 4, wherein the contact actuator is attached to the molded frame so that said actuator touches the free ends of the contact blades which are located on a side of said contact assembly opposite to that side which is adjacent said base member.
Claim 7
Dependent Claim
15 words
A timing device as in claim 1, wherein the molded frame is made of plastic.
Claim 8
Dependent Claim
47 words
A timing device as in claim 1, wherein the contact assembly is attached to the molded frame so that said contact assembly is arranged in a narrow space located between said molded frame and said housing, said molded frame and said housing both being made of plastic.
Claim 9
Dependent Claim
42 words
A timing device as in claim 1, wherein the terminals of said timing device are located at the bottom side of the device adjacent said base member and the time setting means is located at the top side of said timing device.
Claim 10
Dependent Claim
16 words
A timing device as in claim 1, wherein said housing is attached to said base member.
Claim 11
Dependent Claim
35 words
A timing device of claim 9, wherein said housing and said base member form a substantially closed space in which said motor, contact assembly, contact actuator, electromagnet, means for coupling, and molded frame are enclosed.
Claim 12
Dependent Claim
113 words
A timing device comprising: a molded plastic frame; a plastic housing covering said molded frame; a contact assembly attached to a side portion of said molded frame; a contact actuator attached to a top portion of said molded frame; an electromagnet for resetting said control actuator arranged on another side portion of said molded frame and attached to a projection on said molded frame; camming means mounted to said frame causing movement of said contact actuator; a motor arranged in a space enclosed by said molded frame and attached to said molded frame for controlling movement of said camming means; and, a base member attached to a bottom portion of said molded frame.
Claim 13
Dependent Claim
113 words
A timing device comprising: a molded plastic frame; a plastic housing covering said molded frame; a contact assembly attached to a side portion of said molded frame; a contact actuator attached to a top portion of said molded frame; an electromagnet for resetting said control actuator arranged on another side portion of said molded frame and attached to a projection on said molded frame; camming means mounted to said frame causing movement of said contact actuator; a motor arranged in a space enclosed by said molded frame and attached to said molded frame for controlling movement of said camming means; and, a base member attached to a bottom portion of said molded frame.
