To (ZZZ whom it may concern I Be it known that I, Jot-IN T. Honfon, a citizen of the United States, and a resident of New York, borough ofBroolrlyn, in the county of Kings and State of New York, have invented certain new and useful 1m? provements inFall-ltope Carriers, of which the following is a specification.

This invention relates to fall ropecarriers and has for its object to provide a device of the class specified in which themow ing parts are mounted and guided for free movement and in which the frictionincident to such movement is reduced to a mini. mum.

My invention is in the natureof improvements upon the device of United States Patent 1003261, granted September 12,1911,

. Horton and Deline.

section is taken on line 2, 2 of Fig. 1.

In the drawings accompanying this specificationI have illustrated the preferred e1nbodiment of my improvements wherein Figure 1 is a side elevation of a fall rope carrier. Fig. 2 is an elevation, partly in section, of what is shown in. 1. The Fig. 3 is a detail view, partly in section, corresponding with the lower part of Fig. 2. Fig. 4 is a rear view of a portion ofwhat is shown in Fig. 1.

As the general function of fall rope carriers is well known it is deemed unnecessary to illustrate the present device in connection with other parts of the cableway or to de scribe other than briefly, the general operation of such a carrier.

One of the objects of the present improvements is to reduce friction and undue wear in the parts thereof due to a tendency of the driving or traction line f to deflect the floating frame, including members 5, 6, 7 and 8, from its normal general plane of movement.

Another obj ect of my improvements is to prevent the return run l of traction line t and the hoisting or fall rope 9, from becom ing unseated in their respective supporting wheels 10, 11.

Mounted in main frame 12 are two cable traverse wheels 13, 14- and depending from said main frame between said wheels is frame member 15 rotatably. mounted in which are wheelsflfl and 11 above referred to. Traverse wheels 13, 14: engage and are supported by the usual. main cable 16. Coaxially fixed relatively to wheels 13, 14 are drive Wheels as 1.7 and rotatably supported specification bf Letters Ifatenc. Application filed November 21, 1912. Serial No. 732,704.

on swingable arms 5, 6 pivoted to main frame 12 are gripper wheels 19,320 respectively for engagement with the: underside of cable 16; flcnsion wheel are; .rotatably mountedin the upper ends respectively of links 7 and 8 and the lower eiidsof said links are pivotally attached to arms 5, 6,

preferably coaxially with gripper wheels 19, 20, respectively. 1 As traction line 4 is necessarily lodated at one side of the vertical. plane through main cable 16 the tendency of that traction line is to deflect to the right, Fig. 2, the upper part of. thefloating framecomprising members 5, 6, 7 and 8 and to. deflect to the left the lower parts of that floating frame. For maintliining said floating frame, including swingable arms 5, 6, in its normal plane of movement and for preventing sidewisc de flection thereof I provide means including a resistance bar 25 which may beconvcniently bolted to rear member 15 of frame 12 with the outreaching ends of that bar in close proximity to the heads as 26 of pivotal bolts 91 and. 23 whereby said bolt heads and rear swingable arms 5, 6 are permitted free movement in their normal plane of action but are prevented from deflection to the left, Fig. 2. By thismeans any tendency of swingable arms 5, 6 .to defiect to the left, Fig. 2, is prevented.

Just above rope supporting wheel 11,

groove of wheel 11 as shown in Fig. 3. Also said wheel 27 ispreferably mountedfor free movement lengthwise its axis as illustrated, so as to permit evenv wear on its cylindrical surface. Also as this wear is rather severe I preferably mount said wheel upon an cccentric bushing 29 so that by loosening the nut of bolt 28 said bushing may be rotated to adjust wheel 27 relatively to rope supporting wheel 11. Rope supporting wheel 10 may also be provided with a second wheel 30 for engagement with its rope 4 for bold ing said rope in engagement with supporting wheel 10. a I claim: a 1. A fall rope carrier including in combination, two supporting cable traverse wheels rotatably mounted in fixed relation to each other, a gripper wheel. for engagement with the under side of the supporting cable and rotatably mounted in the free end of a swingable arm, a tension wheel for engagement with the upperside ofsaid driving line and rotatably mounted inthe upper end of a second swingable arm, the free ends of the gripper wheel and tension wheel arms being linked together, and means remote from the fixed axes of said swingable arms for maintaining said swingable arms in their normal planes of movement respectively.

2A fall rope carrier including in combination, two supporting cable traverse wheels rotatably mounted. in fixed relation to each other for engaging the upper side of the sup: porting cable, a wheel mounted coaxially with and fixed to each cable traverse wheel for engagement with the lower side of the driving line, a gripper wheel for engagement with the under side of the supporting cable and rotatably mounted in the free end of a swingable arm the other end of which is rotatably mountedo-n an axis fixed relatively to the cable traverse wheels, a tension wheel for engagement with the upper side of said driving line and rotatably mounted in the upper end of a second swingable arm, the free ends of'the gripper wheeland tension wheel arms being linked together, and means remote from the fixed axes of said swingable arms for maintaining said swingable arms in their normal planes of movement respectively. b

3. A fall rope carrier including in combination, two supporting cable traverse wheels rotatably mounted in fixed relation to each other, a gripper wheel for engagement with the under side of the supporting cable and rotatably mounted in the free end of a swingable arm, a tension wheel for engagement with the upper side of said driving line and rotatably mounted in the upper end of a second swingable arm, the free ends of the gripper wheel and -tension wheel arms being linked together, and means between said swingable arms and said main frame for maintaining said arms in their normal planes gripper wheel and tension wheel arms being linked together, and a resistance bar fixed to said main frame and coacting with said swingable arms for preventing sidewise deflection of said swingable arms.

5. A fall rope carrier including in combination, two supporting cable traverse wheels rotatably mounted in fixed relation to each other for engaging the upper side of the supporting cable, a wheel mounted coaxially with and fixed to each cable traverse wheel for engagement with the lower side of the driving line, a gripper wheel for engagement with the under side of the supportlng cable and rotatably mounted in the free end of a swingable arm the other end of which is rotatably mounted on an axis fixed relatively to the cable traverse wheels, a tension wheel for engagement with the upper side of said driving line and rotatably mounted in the upper end of a second swingable arm, the free ends of the gripper wheel and tension wheel arms being linked together, and means between said swingable arms and said main frame for maintaining said arms in their normal planes of movement respectively.
