""IMPRQIIEIyII-:NT IN ENDpLEss WIRE-ROPE WAYS.

.l Specificationforming part of Letters Patent No. 115,310, dated May 30, 1871.

l To all whom` it may concern:

Beit known that LANDREW SMITH HAI.`

l .LIDIE, of San Francisco, `in the county of San l Francisco andin the State of California, haveinvented an ImprovedEndless Wire-Rope'Way, of `which the `following is a specification, reference being had tothe accompanying draw- This invention relatesto `that class of endless wire-'rope ways or wire tram-ways in which- .l the cars or buckets are secured by means of suspensionrods to hangers or carriers perma- `nently attached to theirope, said hangers or carriers consistingl essentially of a projecting arm fastened tothe ropeby a-thin steel clasp or other suitable devicein such a manner as not to interfere with the guidesor pulleys over or aroundlwhich the rope may pass. rEhe ob-y ject of this invention is to so improve the details of constructionthat bearing-pulleys with `deep grooves maybe used along the line for sustaining the rope. rIhis I accomplish by the employment of a hanger or carrier, consisting `of an armsecured by a thin steel band or oth "er suitable device to the` upper part of the rope, and proceeding fromthe rope upward so as to clear the sides or faces of the vgrocive,-and projecting over the upper and outer edge of the groove and terminating in a suitable horizonl tal wrist or joint to which the suspension-rods are attached. l In order that a carrier or hanger constructed in this manner may pass freely around the horizontal pulleys used at the ends of` the Vline, the `upper face of the grooves of j said pulleys `must be made to flare as much as j is necessaryr to` clear the hanger and its fasteners, much more, of course, than when a hanger is used which proceeds from the upper and `outerquarter of the rope, and the upper face l. of which is horizontahbr nearly so, and on a tangent to the top of the rope, and with which `the depth of the grooves in the bearing-pulp `leys used does not greatly exceed half the diameter of the rope. l In the accompanyingdrawing Figures 1 to 6`represent forms of myimproved hanger. Fig.

" i l `7 represents a form of end .pulley suitable Vfor 1 f the formsof `hanger shown in the drawing.

`Each part is distinguished by the same lety ter whenever it appears in the drawing.

A is the hanger, consisting, essentially, of an arm, B, secured to the upper part of the rope G by the thin steel band G, and proceeding fromL the rope upward so as to clear the sides or faces of the groove D of the bearing-pulley E, and projecting over the upper and outer edge F of the groove, and terminating in a horizontal wrist or `joint, H, to which the ,sus pension-rods are attached. I is the end-pnl ley. J is the groove, the upper face of which is vertical, forming a drum or cylinder, K, in order to clear the vertical inner faces of the hangers of the forms shown in the drawing. In each ofm the forms shown the hanger consists of a horizontal plate, L, a vertical part, M, and the thin iron or steel band G. In Figs. l, 2, and 3 one end of the steel band is secured to hooks O on the end of plate L. The other end of the band terminates in a screw that passes through a hole Ain L, the vertical part` `M being a block fitting snugly between the plate L andthe rope. The whole is secured firmly together by screwing down the nut P. With this construction of hanger the cylindrical part of the end pulley may be as high as desired, to prevent the possibility of the escape of the rope* over the upper edge. The parts may be secured together by riveting, as shown in 4, or, instead of rivets, both `ends of the band N may be provided with a nut and screw, and the form of the faces of the. pulleys may be modified accordingly. In Figs. 5 and 6 the plate L, the vertical part M, and the band VGrare all forged in one piece. The band G is tightened around the rope by means of a key driven through the key-way R, and is secured by rivets S. To prevent the escape of the rope from the groove D, pulleys 'I may be placed immediately over the bearv an arm, B, secured to the upper part of the y rope C, and proceeding from the rope upward so as to clear the sides of faces of the groove D of the bearingpulley E, and projecting over the upper and outer edge F of the groove, sub- 2 1 :159ste stantially as herein described, and for the -purl 4.
