SOLAR ORIENTATION DEVICE
First Claim
Patent Images
1. A servomechanism for orienting an item of equipment with respect to a moving heat source comprising:
- a base member, at least three bimetallic beams restrained by support means mounted on said base member, crank means rotatably mounted with respect to said base member, means operably connecting said crank means and said bimetallic elements comprising at least three connecting links rotatably attached to said crank means, wherein said bimetallic beams are arrayed in a manner such that radiant heating from said heat source will cause said bimetallic beams to deform and thereby initiate movement of said item of equipment to cause it to track said moving heat source.

Abstract
A servomechanism apparatus which will continuously track a moving heat source through its plane of travel. A plurality of bimetallic elements are connected to a crank on an orientation shaft in a manner such that as the elements individually deform under radiant heating, they will actuate the crank and rotate the orientation shaft in a direction corresponding to the direction of movement of the moving heat source.

2. The servomechanism of claim 1 wherein said support means comprise thin flexible strips which will allow the beam ends to deform laterally and rotationally when said beams are subjected to said radiant heating.
-
3. The servomechanism of claim 2 wherein said thin flexible strips comprise bimetallic elements which deform when subjected to a temperature change.
-
4. The servomechanism of claim 1 wherein said bimetallic beams eacH comprise a plurality of transversely oriented corrugations, and said connecting links comprise pretensioned wirelike means.
