UNITED STATES PATENT OFFICE.

LYMAN D. HOWARD, OF COLUMBUS, OHIO, ASSIGNOR TO JOSEPH A.

JEFFREY, or

DEVICE. FOR LOWERING SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 545,201, dated August 27, 1895.

Serial No. 383,432. (No model.)

To 66 whom, it may concern:

Be it known that I, LYMAN D. HOWARD, a citizen of the United States, residing at O- lumbus, in the county of Franklinand State of ()hio, have invented certain new and use i'ul Improvements in Devices for Lowering and Delivering Coal or other Materials, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improved mechanism for receiving and temporarily storing or lowering and delivering materials of certain sorts, such as coal, grain, rise. It is well known that in handling, transporting, and piling coal there is much loss incident to the breakage and abrasion of the particles, especially where the coal is allowed to fall a considerable distance, as when delivering it from the cars through the trestles at wharfage points.

The object of the present invention is to provide a means for receiving coal at points where it is to be lowered or piled. The de vices I employ can be also used to prevent impairing the appearance and quality of the coal from exposure and preserve the luster and freshness of appearance, which, as is well known, enhances its marketableness.

Theessential features of the invention can be embodied in several forms. In the drawings I have shown some of the simple forms of devices adapted to carry it out.

Figure 1 is a top plan view of a mechanism embodying my invention. Fig. 2 is a side view of the chute-sections. Fig. 3 is a vertical section of one of the chute-sections. Fig. 4. is a side elevation of a mechanism similar to that in Fig. 1, it having a modified form of guide and suspending device. Fig. 5 is a top plan view of the tube-section shown in- Fig. 3. Fig. 6 is a section on line as :r, Fig. 2.

A A A A represent a series of verticallymovable chute-sections, A being the top one of the series, A the bottom one, and A A the intermediate. They may be of any suitable shape, dimensions, and capacity. Preferably they are constructed so as to easily telescope one with another. They may be circular or angular in section and cylindrical in general form or otherwise shaped. As shown, each is of the form of a frustum of a cone, all being substantially equal in size and capacity. They are open at bottom and top. Each is provided at the upper end with an exterior ring H, which not only strengthens the chute-section, but also can be utilized for carrying guides, suspending devices, stops, &c.

G G are arms extending outward from the sides of the ring on the bottom cone A and adapted to have one or more cables, chains,

The cable shown at K passes over sheaves, such as that at N, and thence to an engine for lifting the vessels.

The chute-sections can be suspended from each other, if desired, in such way that when .they are lowered each will be stopped and held at a predetermined place, but from which it can be lifted upward as soon as those below it have been drawn up far enough to come into engagement with it. This can be done by connecting each to the next by two or more chains; but when very heavy materials such as coals-are to be manipulated it is desirable to provide a lateral-support'bracing and guiding for the series of chutesections supplemental to the vertical support above described. For thisI prefer to employ one or more rigid guides, each having a beam G, arranged to prevent the chute-sections from swaying laterally in either direction. In the construction shown this is accomplished by providing each chute-section with a plate or arm 13 opposite each guide G and bearing against it.

In Fig. 1 there are two guides G G diametrically opposite and two plates 13 B, the guides being supported by a frame having posts E E and girts F F and the chute-sections A A A being at the center vertically of this frame. The plates or arms B are recessed or have extensions C O, which lie by the sides of the guides G and act to still further steady the vessels.

In Fig. 4: a mechanism is shown having only one rigid guide G, the chute-sections being connected on the opposite side by chains M, secured at the ends to eyes M. The rests for the chute-sections are provided by brackets J each adapted to engage with one only of the vessels. This can be readily done by hHV'.

ing the recesses in the end of the plates B on or other suitable supporting means attached.

each chute-sectionextend inward a little far ther than that on the one above and having the rests or stops J situated gradually nearer the center of the vessel. As shown, the edge of the guide G is inclined inward and down ward, so as to bring the stops J to the desired points. It will be seen that whenthe series of chnte-sections is lowered the lower ones will all pass below the upper stops J; but the upper one will engage it and rest upon it till all are again elevated, and the same is true of each in turn. The ends of the parts 0 can bear against verticalflanges I I, formed on or secured to the guide bars G.

'iVhat I claim is- I 1. In a coal lowering or piling mechanism,

the combination of an upper supporting frame, a'downwardly extensibledelivery dnct'formed of a series of duplicate conical downwardly narrowing sections, the upper section supported from said frame, one or more ropes extending downward to thefbottom section and adapted to elevate the sections below the upper one, a guide or brace for preventing lateral movement of the sections, and stops for preventing the sections from escaping re spectively one from the other.

2. In a coal lowering or piling mechanism, the combination of the top supporting frame, a downwardly extensible duct formed of overlapping sections with the upper section supported from said frame, one or more ropes secured to the lower section for elevating it and lifting those above it, the movable sections of said series being provided at their upper ends with laterally extending guide or brace arms,

sides of the said sections, and stop devices on each movable section engaging with stop devices on the section above it tolimit their body and one or more laterally extending supporting projections,0ne or more vertical series of stationary supports or rests, each of said series being adapted to engage with one of one or more stationary guides or braces at the I the supportingprojectious on a section of the delivery duct, and an elevating rope eonnected to thelowermost section, whereby each section can be'vertically supported independ ently of the others, but they can all be elevated together when the bottom one is lifted, substantially as set forth.

In testimony whereof I affix my signature in presence of two'witnesses.

LYMAN D. HOWARD.
