Application filed November trap doors, and said chutes being provided with means for cooperating with the doors for opening the doors sufiiciently to allow the discharge of ore from the chute into the bins,

and subsequently allow the doors to drop down to closed position.

The particular structural details andtheir relative arrangement and association will be come more readily apparent from the following description and drawings.

In the drawings Figure 1 represents a fragmentary top plan view showing the general assembly and cooperation of parts, certain of the trap doors being broken away and certain trap doors on the opposite sides being twisted to open position.

Fig. 2 is a side elevation showing the details of the trap door lifting means.

Fig. 3 is a transverse sectional view through the upper part of a bin constructed vin accordance with the invention with the tripper and its chutes in elevation.

Fig. 4 is an exaggerated longitudinal section through the discharge end of one of the chutes.

Attention is first invited to Fig. 3 wherein it will be observed that the storage bin is denoted by the numerals 9 and 10. The numeral 11 designates generally a supporting or central roof structure or the like of appropriate arrangement. Embodied in this structure are spaced parallel T-beams 12. These constitute supports for the rails 13 and the rails serve to accommodate the transporting means of the tripper. The tripper is generally denoted by the numeral 1 1 and comprises i a container having a pulley l5 accommodat- 1, 1930; seriaina aeasie;

In this connection, I call attention: to the flat formation; the slot oneach side being: 'defi'ned'by horizontalwooden stringers mt and 1 9.

Inasmuch as the, chutes are providing with lifting shoes on the discharge ends, as the shoes rise beneath and are in sliding contact 'I claim as new is with the doors, it is evident that the doors are lifted and the ore slid into the bins in an efficient manner.

The present embodiment of-the invention has been disclosed in considerable. detail merely for the puropse of exemplification since in actual practice, it attains the features of advantage enumerated as desirablein the statement of the invention and the above description.
