SUPPORT FOR AERIAL WIRE ROPEWAYS.

SPECIFICATION forming part of Letters Patent No. 591 ,221 dated October 5, 189'?- Application filed December 18,1896. Serial No. 616,141. (No model.)

To all wfwm it may concern:

Be it known that I, JULIUS S. LANE, a citizen of the United States of America, and a resident of VVestport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Supports for AerialWire Ropeways, of which the following is a specification.

My invention has reference to aerial wire ropeways or rope haulage systems, and has for its object to render such systems available in the formation of dumps.

To this end my invention consists in rendering the standards or towers carrying the sheaves vertically adjustable, so that they may be progressively raised as the height of the dump increases.

The nature of my invention willbest be understood when described in connection with the accompanying drawings, in which- Figure 1 represents a perspective view of a tower embodying my invention. Fig. 2 is a detail sectional view, on an enlarged scale, illustrating the connection between the piles and the tower or standard. Fig. 2* is an end View of the top of the pile. Fig. 3 is a diagrammatic plan view illustrating a rope system going out and returning on a single line of standards or towers embodying my invention. Fig. 4 is a transverse section thereof. Fig. 5 is a side elevation. Fig. 6 is a diagrammatic plan view illustrating a circuit-line. Fig. 7 is a transverse section of Fig. 6. Fig. 8 is a vertical section illustrating modified means for progressively raising the standard or tower. Figs. 9 and 10 are face views of details thereof.

Similar letters and numerals of reference designate corresponding parts throughout the several views of the drawings.

Referring at present to Figs. 1, 2, 3, 4, and 5 of the drawings, the letter A designates a standard or tower, which may be of any suitable form and construction, but which in the present example I have shown in the form of a braced triangular structure. The standard or tower, as usual, is provided with a hanger 1, having bearings for the carrying-sheaves 2, over which passes the rope or cable 3, to which the buckets or carriers 4 are connected. The standard or tower is in the present instance supported upon three screw-piles of therein.

diameter of the screws and the holes filled with sand after the insertion of the piles If applied to existing sand-dumps, the piles may be screwed directly into the dump. In the present instance (Fig. 2 especially) I have shown each of the swivel-joints composed of a cap 6, attached to the head of the respective pile and provided with a spherical top 7, fitted into a socket 8, formed in the base of the standard or tower. The cap is secured to the base of the tower by means of a bolt 9. By applying a suitable wrench to the caps, which may be provided with square heads, or by applying a wrench to the piles the standard or tower can be raised progressively with a minimum expenditure of labor. The line may be constructed to go out. and return on the same line of standards or towers, as shown in Figs. 3, 4, and 5, or it may be constructed in the form of a loop, going out on one set and returning on another set of standards or towers, thus making a wider dump and with a depression in the center, as shown in Figs. 6 and 7.

In case of rock-dumps it may not be found practicable to unscrew the pile, and for such a case I provide the construction shown in Figs. 8, 9, and 10. In this'construction the standard or tower is raised relatively to the piles, the latter remaining stationary. For accomplishing this end I attach to the shank of the pile a split'clamp 10, provided with nuts 11, adapted for the reception of adjusting-screws 12. Said screws engage at their upper ends with a split head 13, secured to the pile, and intermediate of the same and the base of the standard or tower is secured a split bushing 14, upon which rests the base of the standard or tower. Above the base is secured a collar 15 to hold the said base down. By turning on the screws 12 12 the I i as a ropeway, and the latter is therefore prefstandard or tower can be progressively raised with the increase in the height of the dump. When necessary, an additional length of pile is-coupled to the end 16 of the pile, and the several operative parts are readjusted to correspond.

In case of completion of a rock-du mp where the material is so course that the screw-piles cannot be removed by the process of unscrewing it is my purpose to arrange for detaching the pile from the bottom screw by withdrawing the pile and leaving the screw in the dump. This maybe accomplished by threading the screw to the shank of the pile, so that on unscrewing the pile it will leave the screw.

It is of course to be understood that I do not wish to restrict myself to any particular form for the standards or towers, or for the piles, or to any particular conveying system, the main feature of my invention being the provision of means for progressively raising the standards or towers in aerial wire ropeways or wire-rope haulage systems. It is also to be understood that in place of an aerial ropeway a line of tramways or light bridges supported on screw-piles could be used in the same way; but these would not be as flexible erable.

I am aware that heretofore aerial roadways have been constructed with a view of alternately raising and lowering the supports for the track for effecting the propulsion of a car in either direction by gravity. Such constructions I do not claim, as my invention relates particularly to means for progressively raising the track as the dump is built up or its height increased, with aview of keeping the track at a proper elevation above the dump.

What I claim as new is 1. An aerial tramway comprising means for the transportation of sand or minerals, and a series of supports for said means for trans portation individually provided with means 1" or their progressive raising as the dump is built up or increased in height, substantially as and for the purpose set forth.

2. A support for aerial tramways, combined with one or more screw-piles rotatively connected therewith to adapt the structure for progressive raising as the dump is built up, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 9th day of December, 1896.

JULIUS S. LANE.
