Abstract
Abstract A device for lifting and manipulating hot trays, principally aluminum foil containers for food products, is constructed with a substantially tubular, insulating handle, and a pair of cranked tines projecting from the forward end of the handle. The separation between the tines, corresponding to the lateral dimension of the tray to be lifted, is adjustable by means of radial slots machined around the periphery of a bezel in the forward end of the handle and by allowing for the radial displacement of one, or both, of the cranked tines in the handle into engagement with a particular slot.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
A hot tray manipulating device, comprising: handle means, a pair of lifting tines, each of said tines comprising a root segment, a cranked portion substantially orthogonal to said root segment, and a forward segment substantially parallel to said root segments, socket means for retaining said root segments of said pair of tines rotatably mounted in said handle means with said segments in parallel relation and said cranked portions in angularly displaced relation, and adjusting means comprising plural retaining means on the handle means for selective engagement with the tines to provide selected angular displacement between said tines.
Claim 2
Dependent Claim
97 words
A hot tray manipulating device, comprising: handle means, a pair of lifting tines, each of said tines comprising a root segment, a cranked portion substantially orthogonal to said root segment, and a forward segment substantially parallel to said root segments, socket means for retaining said root segments of said pair of tines rotatably mounted in said handle means with said segments in parallel relation and said cranked portions in angularly displaced relation, and adjusting means comprising plural retaining means on the handle means for selective engagement with the tines to provide selected angular displacement between said tines.
Claim 3
Dependent Claim
49 words
The device of claim 1, wherein: said adjusting means include at least two slots in the peripheral portion of said handle means, said slots radiating from a socket means orifice in which one of said tines is rotatably mounted and adapted for retaining the tine against relative angular movement.
Claim 4
Dependent Claim
36 words
The device of claim 2, additionally comprising bias spring means in said handle means for urging the root segment of said one of said pair of tines into engagement with a preselected one of said slots.
Claim 5
Dependent Claim
62 words
The device of claim 3, additionally comprising: at least two other slots in the peripheral portion of said handle means, said slots radiating from a socket means orifice wherein the other of said tines is retained; and a bias spring in said handle for urging the root segment of said other tine into engagement with a pre-selected one of said other slots.
Claim 6
Dependent Claim
46 words
The device of claim 1, wherein said adjusting means include a bearing orifice in said socket means for the rotationally free retention therein of one of said pair of tines, and torsional bias spring means for urging said one tine into proximity with the other tine.
Claim 7
Dependent Claim
33 words
The device of claim 5, wherein said adjusting means additionally include lever means for manually displacing said one tine relative to the other tine against the urging of said torsional bias spring means.
