A load cell is interposed between one end of the bottom chord of the truss and the table flange and a block is interposed between the opposite end of the bottom chord and the table flange.  A flattened flexible tube is disposed on edge along a similar flange on the opposite side of the table.  Blocks are inserted between the flexible tube and the top chord of the truss to simulate a uniform snow load when the tube is inflated.  One-half the total load is measured directly by the load cell and the deflection of the center of the bottom chord is measured by a scale on the table. If the deflection remains within an allowable amount so as to not close a limit switch within a prescribed loading interval, a timer actuates a rubber stamp to mark the truss as having passed the test.

Abstract: ABSTRACT OF THE DISCLOSURE     A time-lag fuse is provided which exhibits improved breaking capacity due to its novel construction.  It comprises a fuse element which is securely positioned within an insulating cylindrical tube such as a glass cartridge, and a plurality of sintered ceramic bodies (e.g., cylindrical or polygonal) are circumferentially disposed within the tube so as to define a space therewith to achieve the required fusing and time-lag character-istics.  The sintered ceramic bodies are arranged so as to define a plurality of spaces between adjacent pairs of the ceramic bodies and the insulating tube in order to buffer the pressure created by arcing between the ceramic bodies and the insulating tube during a current overload.  The fuse of the present invention overcomes the drawbacks of the prior art devices which include, for example, difficulty in stabilizing fuse characteristics.
