IMPROVEMENT IN ELEVATED WIRE-WAYS.

Specification forming part of Letters Patent No. 142,5, dated September 16,1873; application filed June 26, 1873.

1'0 all whom it mayfconcem:

Be it known that we, HENRY T. LANTIS and NELsoN DAVIS, of Atlanta city, Alturas county, Territory of Idaho, have invented an Improvement in Wire-Rope Ways; and we do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the-art or science to which it most nearly appertains to makeand use our saidinvention or improvement withoutfurther invention or experiment.

Our invention relates to improvements in the rope or tram ways in which a traveling endless wire-rope is suspended at intervals upon pulleys-or other supporting mechanism for the purpose of providing a medium for transporting freight from one place to another.

Our improvements consist of a novel construction and arrangement of the pulleys which support the rope, and a peculiar pendant from the rope'for supporting the weight or load to be transported, the two being so arranged that the pendant can pass between the pulleys in a vertical line from the middle of the rope, thus permitting theload to be suspended directly below the rope without the intervention of saddles or angular pendant-rods, such as are in use at the present time.

In order to more fully explain and describe ourinvention reference'is had to the accompanying drawings forming a part of this specification, in which- Figure l is aview of our machine, showing an edge view of the pulley, and a transverse section of the rope. Fig. 2 is a side sectional elevation.

Let A represent the upper cross timber of the frame-work which supports the wirerope at-any one. point. This cross-timber we divide in the middle into two parts by cutting away a transverse section at b, Fig.2, of the "required width, or the cross-timber may be made of two separate pieces of timber, whose ends are separated the reqnireddistance apart. In order to support these separated ends weemploy an inverted U-shaped block or casting, 0, the opposite legs or sides of which are secured upon the opposing ends of the timbers, so that it will form a bridge above the slot or space I) for supporting the two ends of the timber. Proper braces will. also be used I forholdingthepartsofthecross-timberinplace. D D are two half-pulleys, each of which has a when the pulleys are'placed with their grooved edges together, a complete pulley groove will be formed. Two horizontal shafts, f, are

ity of this plate supports the upper end of an oval metal framev orloop', K, the lower end of which i's formed of two parallel plates which hers A, so as to form a passage, S, Fig. 1, which will bein line with the passage between stand. at an angle to the timber A, and, being contracted at the lower end until the narrow passage isformed, it will serve as a guide forthe purpose'liereinafter described. M represents' the rope which is used in this classot' tramway. This rope will pass through the U-shaped casting or bridge, and lie in the groove formed by the two half-pulleys D D. To this rope at intervals we secure apermanent hanger or pendant, 0, the lower end of which is provided with a hook, 1), upon which the load or weight to be transported is placed.-

This pendant is secured by athin plate of sheet passage between the half-pulleys when the rope is moving. The oval frame K, with its pass'age S, serves to guide the plate t of the pendant into the passage between the halfpulleys. I

By this means we provide a strong and substantial bearing for the rope, and one which will permit of the use of 'a pendantwhich hangs vertically from the rope, thus avoiding the great cost and inconvenience consequent on using the saddle and bent pendant.

In witness whereof we hereunto set our 4 hands and seals.
