Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A bread baker including; an oven; a pair of plates within said oven and arranged to be positioned within a baking pan on opposite sides of a quantity of bread dough within said pan; a driver engaging said plates and arranged to move said plates towards and away from each other to squeeze the bread dough between the plates; and, a controller coupled with said driver and with means for heating said oven, and arranged to activate said driver to squeeze said bread dough at a first predetermined time following a first predetermined time interval, and to activate a selected one of said driver and said means for heating said oven following a second predetermined time interval subsequent to said first predetermined period of time and time interval.
Claim 2
Dependent Claim
128 words
A bread baker including; an oven; a pair of plates within said oven and arranged to be positioned within a baking pan on opposite sides of a quantity of bread dough within said pan; a driver engaging said plates and arranged to move said plates towards and away from each other to squeeze the bread dough between the plates; and, a controller coupled with said driver and with means for heating said oven, and arranged to activate said driver to squeeze said bread dough at a first predetermined time following a first predetermined time interval, and to activate a selected one of said driver and said means for heating said oven following a second predetermined time interval subsequent to said first predetermined period of time and time interval.
Claim 3
Dependent Claim
55 words
The bread baker of claim 1 wherein said controller is arranged to activate said driver to squeeze said dough at a second predetermined time following said second predetermined time interval and to activate said means for heating said oven after a predetermined time interval subsequent to said first and second predetermined times and time intervals.
Claim 4
Dependent Claim
38 words
The bread baker of claim 1 wherein said controller is arranged to activate said means for heating said oven for a predetermined heating period following said second predetermined time interval and then to deactivate said means for heating.
Claim 5
Dependent Claim
39 words
The bread baker of claim 1 wherein said controller includes a plurality of interval controls each operative to determine a respective one of said time intervals and adjustable to permit said respective time interval to be varied in length.
Claim 6
Dependent Claim
80 words
The bread baker of claim 1 wherein each of said plates is arranged to be positioned generally vertically and parallel to the other of said plates with the lower edges thereof adjacent and parallel to the bottom of said pan, and wherein said driver engages an upper portion of each of said plates and moves said upper portions towards and away from each other thereby pivoting said plates towards and away from each other generally about the lower edges thereof.
Claim 7
Dependent Claim
77 words
The bread baker of claim 5 wherein said driver includes a pair of plate engagers, each of said plate engagers defining a recess engaging opposite sides of a said plate upper portion in such a way as to permit relative sliding movement between said recess and said plate upper portion, and said driver being operative to move each of said plate engagers reciprocally back and forth along a line generally perpendicular to the planes of said plates.
Claim 8
Dependent Claim
53 words
The bread baker of claim 5 wherein said driver includes a pair of parallel driver rods each mounted generally perpendicular to the planes of said plates for reciprocating axial movement, a plate engager coupling each of said rods with one of said plates, and a motor for moving each of said rods reciprocally.
Claim 9
Dependent Claim
24 words
The bread baker of claim 7 wherein said motor moves each of said rods at a speed of about one complete cycle per minute.
Claim 10
Dependent Claim
