FALL-ROPE CARRIER.

Specification of Letters Patent.

atented 13er. 8, 1.9M?.

Application filed April 21, 1913. Serial No. 762,561.

To alt Iwhom it 11mg/ concern Be it known that I, Jol-IN T. Hon'row, a citizen of the United States, and a resident of New York, borough of Brooklyn,`

in the county ot Kings and State of New York, have invented certain new and useitul improvements in Fall-Rope Carriers, oi which the following is a specification.

r1`his invention relates to Yfall rope carriers for cableways.

The object of my improvements is to provide positive means for causing said carrier to traverse the supporting cable and at a predetermined ratio of speed relatively to the speed ot' the driving line.

Another object of my improvements is to provide means for readily changing any given ratio of speed to some other ratio.

Other objects ot' my improvements will appear in the specification and be particularly pointed out in the claims.

lV ith these objects in view the preferred form of my improvements is illustrated in the accompanying drawings wherein- Figure 1 is a side elevation of my fall rope carrier and Fig. 2 is a sectional elevation on line Q, 2 of Fig. 1.

Before describing the invention in detail I desire to have it understood that the invention is not limited to the particular construction and arrangeurentJ of parte which I have illustrated and shall hereinaiter describe, and that various changes may be made in the mechanism without departing from the spirit or scope ot the invention, and that the phraseolog'v which 'I employ is for the purpose of description and not of limitation.

My improvements are herein illustrated as applied to that type of tall rope carrier set forth in Letters Patent of the United States Number 10039.61, granted September 12, 1911, on the joint invention of myself and Edward H. Deline. It will be obvious however to those skilled in the art that my present improvements are equally applicable to a wide variety of types of fall rope carriers and are not restricted to the particular type illustrated.

In the iigures of the drawing 3 is the usual supporting cable, 4 is the driving or traction line, l the return run thereof and 5 is the hoisting or fall rope. Two supporting cable traverse wheels 7, 8 are rotatably mounted on lixed axes supported between horizontal side frames 9, 10. For stability said side frames may be secured to end blocks as Depending side arms 11, 12 are fixed at their upper ends midway the length oil side frames l), 'l0 rcsj'iectively and have rotatably mounted therebetween the usual wheels 13, 'lfi for supporting the return run nl ot drivingline At and 'fall rope 5 respectively. Preferably mounted coaxially with cable traverse wheels 7, 8 are driving wheelsI 15, 1G respectively. These driving' wheels may be of some convenient diameter and are t'ree to rotate indejicndently of their respective. coaxial traverse wheels. (,iripper wheels 1l), E20 are provided tor engagement with the underside ot cable 3 and are rotatably actuated lfrom traverse wheels 7, 8 respectively by means to be hereinafter described. These gripper wheels are also urged upwardly to lgrip cable 3 between them and traverse wheels 7, 8 respectively. Said gripper wheels 19, Q0 are rotatably mounted in the `.tree ends oi arms 21, 22 respectively. Said arms are pivotally mounted at their upper ends in convenient positions in side iframes 9, l0 on pivots Q3, 24, said pivots preferably being' concentric with wheels 7, S all respectively. Said arms 21, 22 are preirably double arms as 21, 21a on each side oit wheel 19.

To 'anse wheelsl 1S), Q0 to grip the underside of cable 3 l provide tension wheel 26 for engagement 'with the upper side ot driving; line --l. Said tension wheel is rotatably mounted at S'll in the upper ends respectively o1 links 2T, 2S, the lower ends ot said links being;` pivotally attached to arms S21, 22, preferably at 29, 30, coaxially with gripper wheels 19, S20 respectively. Thus thef upward urge oi line 4l; under tension wheel 26 will cause that wheel, through links as 27, to pull upwardly gripper wheels as 1.9 to engagement with the under side ot' cable 3.

As my improved device, in that embodiment thereof chosen for illustration, is symmetrical relatively to a vertical plane through the axes of wheels 13, 14 Fig. 1, a further description of those parts on one side of that plane will suflice for both.

For causing gripping wheel 1.) to rotate and thus advance the carrier along cable 3 and I provide driving wheel 15 with gear 17 fixed thereto and concentric therewith and I provide driving wheel 15 with gear 18 similarly tired thereto, said gears being in mesh. Wheel 19 iixed to shaft 21) by pin and gear 17 s removably fixed to lli that shaft by key 82. Vheel 15 is fixed to sleeve 83 by pin 34 and gear 1S is remov ably iiXed to that sleeve by ley Said gears 17, 18 may therefore be readily removed from their respective positions and interohanged or gears of other sizes substi-V tuted, thereby varying at will the ratio of rotation of wheels 15 and 19. iVheel 15 is preferably of larger diameter than wheel 19 so that the traction of driving lineV L1 may be depended upon to rotate lthat wheel against the resistance of the train including gears 18, 17 and wheel 19 and Cause said wheel 19 to rotate against cable 3 and drive the fall rope Carrier along that cable. To provide added eilicieney for such drive, l, in some eases, provide wheel 19 with gear 3G iXed thereto for driving gear 37 of wheel 7. Said wheels are illustrated as of equal diameter and said gears will therefore be of equal diameter as shown.

I claim:

1. A fall rope carrier including in oom'- bination two supporting cable traverse wheels for engaging the upper side of the supporting cable, a driving wheel for engaging the under side of the driving line, a gripping wheel for engaging the under side of the supporting Cable, a tension wheel for engaging the upper side of the driving line, means for driving said gripping wheel from said driving wheel, and means for driving one of said traverse wheels from said gripping wheel. Y I

2. A fall rope carrier including in oombination two supporting Cable traverse wheels rotatably mounted in fixed relation to each other for engaging the upper side of lthe supporting cable, a driving wheel mounted eoaxially with one of said traverse wheels but rotatable independently thereof for engaging the under side of the driving line, a gripping wheel for engaging the under side of the supporting Cable, meansfor driving said gripping wheel from said driving wheel, a swinging arm, one end of which is mounted in fixedA relation relatively to one of said traverse wheels and in the other and free endlo which is mounted said gripping wheel, a tension wheel for engaging the upper side of the driving line and mounted tor movement toward and away from said driving line and means Connecting said tension and gripping wheels for Causing said gripping wheelto engage the supporting cable. y

A fall rope Carrier including in combination two supporting vCable traverse wheels for engaging the upper Aside of the supporting cable, Aa driving wheel for en gaging the underside et' thefdrliving line, a gripping wheel for engaging'tbe under side or the supporting Cable, a tension wheel. tor engaging the upper side ot the driving line, geared Veonneetions between said driving w'ieel and said gripping wheel, and geared connections between one of said traverse wheels and said gripping wheel.

41.11 fall rope Carrier including in combination two supporting cable traverse wheels rotatably mounted in fixedV relation te each other for engaging the upper side of the supporting cable, a driving wheel mounted eoaxially with one of said traverse wheels but rotatable independently thereof, for engaging the under side of the driving line, a gripping wheel for engaging the under side of the supporting cable, a tension wheel for engaging the upper side ot the drivingline and mounted for movement toward and away from said driving line,`geared connections between said driv- 1 ing wheel and said gripping wheel, and geared connections between one of said traver'se wheels and said gripping wheel.

Signed rat New York, in the county of new York and State of Newl York, this 17th day of April, 1913, before two subscribing witnesses.
