Abstract
Abstract A rail is tiltably mounted on a crank arm at one end of the rail or the rail is hung at both ends on pivotal link hangers. In the case of the crank arm, the rail extends from the attached end over center to the opposite side of the crank arm so that when the crank rises or lowers with the attached end of the rail, the other cantilevered end of the rail lowers or rises in the opposite direction to tilt the rail. In the case of the pivotal link hangers, the distance between the pivot points at the hangers is greater than the distance between their connection to the rail so that when one link extends downwardly to lower that end of the rail, the other link extends outwardly to raise the other end of the rail to cause the rail to tilt. A trolley rolls on the rail and supports a container, such as a wastebasket. The apparatus may be mounted on a desk and a wastebasket may be carried by the trolley. By tilting the rail the trolley rolls to the lower end of the rail and carries the wastebasket with it. Operating linkage, stops, etc. are provided to bi-directionally activate the tilt and to prevent overtilt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
Apparatus for extending a container from a housing for use and for retracting a container into a housing for storage, comprising, a rail having an outer end and an inner end; a trolley rollable on said rail for carrying a container; and means mountable on a housing tiltably supporting said rail between a first position inclining downwardly-outwardly to roll said trolley to said outer end of said rail to carry a container to a use position outwardly of a housing and a second position inclining downwardly-inwardly to roll said trolley to said inner end of said rail to carry a container to a storage position inwardly of a housing, said means comprising a shaft, means pivotally mounting said shaft, a crank-arm on said shaft, and stop means for limiting crank-arm angular motion between two points.
Claim 2
Dependent Claim
135 words
Apparatus for extending a container from a housing for use and for retracting a container into a housing for storage, comprising, a rail having an outer end and an inner end; a trolley rollable on said rail for carrying a container; and means mountable on a housing tiltably supporting said rail between a first position inclining downwardly-outwardly to roll said trolley to said outer end of said rail to carry a container to a use position outwardly of a housing and a second position inclining downwardly-inwardly to roll said trolley to said inner end of said rail to carry a container to a storage position inwardly of a housing, said means comprising a shaft, means pivotally mounting said shaft, a crank-arm on said shaft, and stop means for limiting crank-arm angular motion between two points.
Claim 3
Dependent Claim
136 words
In apparatus as set forth in claim 1, a remote end on said crank-arm extending radially from said shaft in a direction inwardly of a housing; said inner end of said rail being fixedly connected to said remote end of said crank-arm to swing angularly therewith; said rail extending from said remote end of said crank-arm past said shaft so that said outer end of said rail is over center and moves angularly in an opposite direction to said crank-arm during pivotal motion of said shaft and said crank-arm to raise said inner end and lower the outer end of said rail to cause said trolley to roll outwardly of a housing and to lower said inner end and raise said outer end of said rail to cause said trolley to roll inwardly of a housing.
Claim 4
Dependent Claim
121 words
In apparatus as set forth in claim 1, said means comprising a near pivotally mounted link-hanger and a remote pivotally mounted link-hanger; said outer end of said rail being pivotally connected to said near link-hanger and said inner end of said rail being pivotally connected to said remote link hanger; the distance between the points of connection of link-hangers to said rail being less than the distance between the pivotal mountings of said link-hangers themselves so that when one link-hanger extends downwardly to lower one end of said rail, the other link-hanger extends sidewardly to raise the other end of said rail to tilt said rail to cause said trolley to roll with a container into and out of a housing.
Claim 5
Dependent Claim
94 words
In apparatus as set forth in claim 2, said rail curving downwardly from its connection to said crank-arm as to lie below the pivotal axis of said shaft and then curving upwardly so as to lie above the pivotal axis of said shaft to provide added downward inclination at said trolley to accelerate it to start its roll when the shaft and crank-arm are actuated to tilt and to provide added upward inclination of said rail to decelerate said trolley to slow its roll when said trolley is reaching the end of its roll.
Claim 6
Dependent Claim
67 words
In apparatus as set forth in claim 3, said rail having upwardly curved ends adjacent its connection to said hanger links to provide added downward inclination at said trolley to start its roll when said rail is actuated to tilt and to provide added upward inclination of said rail to decelerate said trolley to slow its roll when said trolley is reaching the end of its roll.
