Abstract
A high temperature bottom-loading research furnace is provided having a lifting mechanism comprising a V-shaped wheels and corresponding guide members for raising and lowering the furnace oven door. The lifting mechanism facilitates precise opening and closing of the door which, along with other mechanical features, reduces the heat loss from the furnace and, accordingly, reduces the amount of energy needed to operate the furnace.
Claims19
A high temperature furnace for use in laboratories, comprising:
- a control cabinet;
- a support platform underneath the control cabinet, with a portion of the platform extending beyond the control cabinet;
- an elevated furnace oven adjacent to the control cabinet positioned above the portion of the platform extending beyond the control cabinet, the elevated furnace oven having a top, sides, bottom, a chamber, and a door which opens from the bottom of the oven;
- a support frame for securing the control panel, support platform and furnace oven in their respective positions relative to each other;
- and
- a lifting mechanism for elevating the oven door to a closed position at the bottom of the oven, and for lowering the oven door to an open position below the bottom of the oven and above the support platform;
- the lifting mechanism comprising a vertically disposed support panel securely fastened to the support frame, the support panel including two vertically disposed rectangular guide members mounted to a front surface of the support panel, each of the guide members having a V-track along a longitudinal edge thereof;
- the lifting mechanism further comprising a carriage for carrying the oven door, the carriage having at least two V-wheels rotatably mounted thereto, with each of the two V-wheels engaging the V-track on one of the guide members;
- the lifting mechanism further comprising means for raising and lowering the carriage.

A high temperature research furnace for use in laboratories, comprising:
- a control cabinet;
- a support platform underneath the control cabinet;
- an elevated oven positioned laterally of the control cabinet and at an elevation higher than that of the support platform, the furnace oven housing a top, sides, bottom, a chamber, and a door which opens from the bottom of the oven;
- and
- a lifting mechanism which elevates the oven door to a closed position at the bottom of the oven, and lowers the oven door to an open position below the bottom of the oven;
- the lifting mechanism comprising a vertically disposed support panel securely fastened to the support frame, a carriage for the oven door movable vertically at a fixed horizontal distance from the support panel, and means for raising and lowering the carriage;
- the vertically disposed support panel comprising two vertically disposed guide members mounted to a front surface of the support panel, each of the guide members having a vertically disposed V-track along an edge thereof;
- the carriage comprising at least two V-wheels rotatably mounted thereto, with one of the two V-wheels engaging the V-track on each of the guide members.

A lifting mechanism for a high-temperature laboratory furnace, comprising:
- a vertically disposed support panel having a vertically disposed longitudinal slot therein;
- two vertically-disposed rectangular guide, members mounted to a front surface of the support panel, each of the guide members having a V-track along a longitudinal edge thereof;
- a carriage for carrying an oven door, comprising an upright back frame, a horizontal carriage platform, one or more side walls, and four V-wheels rotatably mounted to the back frame such that two of the V-wheels engage each of the two V-tracks;
- a reversible motor mounted to a back surface of the support panel above the longitudinal slot;
- a vertically-disposed threaded rod engaging the reversible motor and extending downward therefrom;
- and
- a connector rod passing through the longitudinal slot, having a first end fastened to the carriage and a second end fastened to the vertically disposed threaded rod;
- such that when the reversible motor turns in one direction the carriage is raised, and when the reversible motor turns in an opposite direction the carriage is lowered.
