Abstract

Abstract A toaster in which a vertical toasting compartment is closed during a toasting operation by means of a movable bottom wall. After termination of the toasting operation the bottom wall is retracted so as to permit the toasted bread to be discharged from the compartment. The retraction of the bottom wall may be automatically controlled by a timing device and it may be effected by swinging the bottom wall downwardly on a horizontal pivot axis. The opposed side walls of the toasting compartment are movable in vertical direction and are coupled to the bottom wall in such a way that the side walls are lifted slightly when the bottom wall is retracted to its discharge position. A lostmotion coupling may be provided between the side and bottom walls so that the movement of the side walls is considerably smaller than that of the bottom wall and is effected in a jerky manner.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 127 words
A toaster, comprising a housing, two apertured walls extending vertically opposite one another within said housing to define therebetween a vertical toasting compartment, heating means located on the opposite exterior sides of said walls, a toasting compartment bottom wall movably supported within said housing between a first position in which it closes the lower end of said compartment, and a second position in which it permits toasted bread to slide out through the bottom of said compartment, wherein said vertical walls are supported for vertical movement within said housing, and a mechanism is provided which connects said vertical walls with said bottom wall so as to move said vertical walls upwardly when said bottom wall is retracted from its said first position to its said second position.
Claim 2
Dependent Claim 127 words
A toaster, comprising a housing, two apertured walls extending vertically opposite one another within said housing to define therebetween a vertical toasting compartment, heating means located on the opposite exterior sides of said walls, a toasting compartment bottom wall movably supported within said housing between a first position in which it closes the lower end of said compartment, and a second position in which it permits toasted bread to slide out through the bottom of said compartment, wherein said vertical walls are supported for vertical movement within said housing, and a mechanism is provided which connects said vertical walls with said bottom wall so as to move said vertical walls upwardly when said bottom wall is retracted from its said first position to its said second position.
Claim 3
Dependent Claim 28 words
A toaster as claimed in claim 1, in which said compartment bottom wall is pivotally supported in said housing on a horizontal axis parallel to said vertical walls.
Claim 4
Dependent Claim 83 words
A toaster as claimed in claim 1, in which said mechanism comprises a tie rod, means supporting said tie rod for vertical movement, means connecting said tie rod with said vErtical walls, a coupling means on said bottom wall, and a lost-motion coupling connecting said tie rod with said coupling means, the lost motion of said coupling being slightly smaller than the movement of said coupling means in response to the movement of said bottom wall between its said first and second positions.
Claim 5
Dependent Claim 48 words
A toaster as claimed in claim 3, wherein said lost-motion coupling comprises a link pivotally connected with the lower end of said tie rod and having an elongated slot therein, and said coupling means comprises a pin secured to said bottom wall and engaging in said elongated slot.
Claim 6
Dependent Claim 89 words
A toaster as claimed in claim 3, wherein a first horizontal slot is provided in said tie rod, and a second horizontal slot is provided in said vertical wall, the means connecting said tie rod with said vertical wall comprises a crankshaft supported for pivotal movement on a horizontal axis and having a first crank engaging in said first horizontal slot and a second crank engaging in said second horizontal slot, said first and second cranks extending in opposite direction relative to said horizontal pivot axis for said crankshaft.
Claim 7
Dependent Claim 30 words
A toaster as claimed in claim 1, wherein said vertical compartment side walls are mounted in said housing with play in a direction perpendicular to the plane of each wall.
