No. 789,381. PATENTED MAY 9, 1905.

SPECIFICATION forming part of Letters Patent No. 789,381, dated May 9, 1905. Application filed September 6, 1904. Serial No. 223A23.

To all whom it may cmwern:

Be it known that I, DANIEL S. Post, acitizen of the United States, residing at Painesville, in the county of Lake and State of Ohio, have invented certain new and useful Improvements in Coal-Chutes; and I do declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in coal-chutes; and the improvement consists in means for adjustably securing two or more chutes together, substantially as shown and described, and more particularly pointed out in the claims. v

The object of this invention is to provide a simple and durable construction which is adapted to adjustably connect two or more chutes together and which comprise means to make one complete chute suitably strengthened to withstand the load and which will not interfere with the passing of the coal or other material through the chute.

In the accompanying drawings, Figure 1 is a perspective view of two sections of my improved coal-chute connected in supporting re lation with each other. Fig. 2 is an enlarged perspective view of the larger or connecting end of one of the sections. Fig. 3 is a perspective view in detail of one of the chainh'ooks for engaging the side of the chute. Fig. 4 is a side elevation of a portion of two sections in connected relation with the hooks engaging the upper edge of the upper chute.

My invention is used mainly for delivering coal from wagons; but it may be used for other purposes, and usually the two chutesections A are sufficient; but more sections may be connected together, and the connecting and sustaining portions of the chute must be constructed accordingly with this end in view. Each chute-section is trough-shaped and tapered with the largest width at the upper end. The object in having them tapered is primarily to permit them to be telescoped together for convenience in cartage and also to permit one chute to slide within the other for adjustment.

The upper edge of each side wall 2 of each section is preferably rounded over and strengthened by a rod 3, running centrally within bead 4C the full length of said sides. A strengthening-band of metal 5 and 6 is secured across the bottom and side of each end of sections A. The reinforcing-band 6 at the upper or larger end of the chute-sections is preferably provided with a depending flange 7 across the bottom of the sections and which has an opening 8 at each side, through which chain 9 is threaded. Hooks 10 at the ends of chain 9 are utilized to engage the upper chutesection either through openings 11 in the sides 2 thereof or clamped to engage over the upper bead i, as shown in Fig. 4. Chains 9are of suificient length to provide a substantially truss connection which is sufficiently strong to hold any two sections together under the weight to be carried. I-Iooks 10 are preferably constructed of semi-oval material to provide an inner flat face 13, which is adapted to make close engagement with the sides 2 of the chute-sections and having a rounded portion 14: where it enters within the chute to provide the least obstruction to the passing coal.

An important advantage over other constructions rests in the free and unobstructed passage for the coal through the chute no matter whether it be small or lump coal and in the further advantage and convenience in adjusting the sections to varying conditions.

What I claim is 1. In coal-chutes, the combination of troughshaped sections constructed to telescope one within the other, and chain-and-hook connec- 5 tions secured to the ends of said sections and adapted to secure said sections together.

2. In coal-chutes, a section substantially as described comprising a trough member having a reinforcing-band at one end with a de- 9 pending flange, a chain attached to the end of said sections and hooks for said chain adapted to engage with other sections.

3. In coal-chutes, tapering trough-shaped sections provided with reinforcing-bands at 4. In coal-chutes, the combination of a plu- In testimony whereof I sign this specificarality of trough-slumped sections constriicted tion in the presence of two Witnesses. to telescope one into tie other, the encs of w 1 said sections overlapping, and flexible connec- DANIEL PObT' 5 tions engaging the end of the lower section at Witnesses:
