Abstract
Abstract A device for use in installing wax foundations in bee frames having side members fabricated from substantially dielectric materials and characterized by a plurality of electrically conductive foundation wires extended in substantial parallelism between the opposite side members. The device includes a table having a planar surface for supporting a bee frame. A pair of elongated electrical contacts of substantially inverted U-shaped configuration are mounted in spaced parallelism on the table for engagement of the mid-portions of the contacts with the opposite ends of the foundation wires whereby a DC voltage can be applied to the wires to heat the wires prior to the wires being embedded in a foundation sheet. The mid-portions of each contact is resilient and compression springs are arranged on the planar surface in supporting relationship with the mid-portions of the contacts to prevent sagging of the mid-portions thereby assuring proper electrical contact between the mid-portions and the foundation wires.

Claim 1
Independent Claim
199 words
A device for use in installing wax foundation sheets in bee frames of the type formed of substantially dielectric material and having a plurality of foundation wires extended in substantial parallelism between a pair of opposite sides of the frames, comprising: A. a table including a substantially horizontally planar surface for receiving in supported relation a bee frame characterized by at least one foundation wire extended between the sides of the frame; B. means for applying a voltage across the foundation wire of a bee frame supported on said surface including a pair of elongated, resiliently supported electrical contacts mounted on said table in spaced parallelism, each contact of said pair being of a substantially inverted U-shaped configuration having a pair of laterally spaced end portions rigidly affixed to the planar surface of the table and projected substantially vertically therefrom, and a resilient mid-portion integrally related to said end portions and extended in spaced relation with said planar surface; and C. means for urging the contacts into engagement with the foundation wire, including a compression spring mounted on said planar surface between the end portions of each of the contacts and disposed in supporting relation with the midportions thereof.
Claim 2
Independent Claim
199 words
A device for use in installing wax foundation sheets in bee frames of the type formed of substantially dielectric material and having a plurality of foundation wires extended in substantial parallelism between a pair of opposite sides of the frames, comprising: A. a table including a substantially horizontally planar surface for receiving in supported relation a bee frame characterized by at least one foundation wire extended between the sides of the frame; B. means for applying a voltage across the foundation wire of a bee frame supported on said surface including a pair of elongated, resiliently supported electrical contacts mounted on said table in spaced parallelism, each contact of said pair being of a substantially inverted U-shaped configuration having a pair of laterally spaced end portions rigidly affixed to the planar surface of the table and projected substantially vertically therefrom, and a resilient mid-portion integrally related to said end portions and extended in spaced relation with said planar surface; and C. means for urging the contacts into engagement with the foundation wire, including a compression spring mounted on said planar surface between the end portions of each of the contacts and disposed in supporting relation with the midportions thereof.
Claim 3
Dependent Claim
23 words
The device of claim 1 wherein the midportion of each of said contacts includes an intermediate segment of a substantially upright U-shaped configuration.
Claim 4
Dependent Claim
23 words
The device of claim 1 further including circuit means adapted to connect the contacts to the opposite terminals of a d.c. voltage source.
Claim 5
Dependent Claim
