FALL-ROPE CARRIER.

I Specification of Letters Patent. -Pate11ted Sept. 12, 1911.

Application filed May 8, 1911. Serial No. 628,004.

To all whom it may concern:

Be it known that we, JOHN T. HORTON and EDWARD H. DELINE, citizens of the United States, and residents of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fall-Rope Carriers, of which the following is a specification.

This invention relates to fall rope carriers for cableways. V I

The object of our improvements 'is' to provide means simple in construction and re liable in operation for supporting the operating ropes of overhead'cableways. "With these objectsin view the preferred form of our improvements. is illustrated in the ac companying drawings wherein Figure l'is a side elevation of our fall rope carrier and Fig.2 is 'a corresponding end elevationpartly' in section. Figs. 3 to 7 inclusive are diagrammatic side elevations to a reduced scale illustrating modifications of our improvements. e

As the general function of fall rope carriers is well known it is deemed unnecessary to illustrate the'present device in connection with the other parts of a cableway.

Our improved device differs from the devices. of ;the prior art of which we. have knowledge in its increased simplicity of construction: and efliciency of operation. In simplicity of construction in that its framework is constructed of fiat bars of commerce without other machine work than shearing to length and drilling. In efiiciencyof operation'in that the supporting cable 'is gripped with a pressure in excess of that exerted by the grip actuating means, said pressure being increased by leverage due to the peculiar arrangement of the parts of our device.

Referring now particularly to Figs. 1 and said side' frames may be secured to end blocks 41, 4:2. Depending side arms 11, 12 arefixed at their upper ends midway the length of side frames 9, 1'0 and have rotatably mounted therein wheels 13, 14 for supporting the return run 4* of traction line 4: and hoisting or fall rope 5. Mounted co- :axia-lly with and fixed to cable traverse wheels 7, S, as by pins 17,18, are drive , wheels 15, 16 respectively. These drive wheels are illustrated as of the same diameter as traverse wheels 7, 8 which will cause the device to traverse cableway 3 at half the speed of'drive line 4. If it is desired to have said fall ropecarrier travel faster or slower than half the speed of drive line 4:, drive wheels 15, 16 or traverse wheels 1 7, 8, or all four must be changed in diameter to correspond withthe desired speed, according to well-known practice. [It will be observed that, to cause the fall rope carrier to travel at half the speed of drive line t, said line could equally well engage the upper sides respectively of traverse wheels 7, 8, 'and tension wheel 26 shifted to the right on pensing with drive wheels 15, 16. To cause traverse wheels 7, 8 to grip cable 3 and travel in rolling contact thereon we provide one or more gripper wheels as 19, '20 for engagement with the underside of said cable. These gripper wheels are rotatably mounted in the free ends respectively" of arms as 21 to wheel 19 and 22 to wheel 20. iSaid arms are pivotally mounted at their upper ends in convenient positions in side frames 9, 10 on pivots 23, 24, said pivots preferably being concentric with wheels 7, 8 all respectively. Arms 21, 22 are preferably double arms as 21, 21 on each side of wheel 19. To cause wheels as 19, 20 to grip the underside of cable 3 we provide tension wheel 26 for engagement with the upper side of traction line 4 preferably between wheels 15, 16. Said tension wheel 26 is rotatably mounted at 31 in the upper ends respectively of links 27, 28, the lower ends of said links being pivotally attached to arms 21, 22, preferably at 29,30 coaxial" with pp wheels 19, 20 resl e ?tively.

Said links 27, 28 are also preferably double as links 27, 27 on each side of wheel 26.

The length of 'links'27, 28 is such that r caused to grip cable 3. Also the arrangement of said links 27, 28 and arms 21, 22

. is such that the upward movement of either by wheels 7,8.

' concentric with wheel 8.

wheel'19 or 20 isless than the upward movement of wheel 26 whereby the gripping power applied by said wheels 19, 20 is greater than the power applied by line 4 to lift wheel 26. It will therefore be .ob-

served that the greater the tension on traction line 4 the greater will be the gripping effect of wheels 19, 20 on the under side of saidcablev 3 and on the upper side thereof By this arrangement any increase in power required to move the load carriage and fall block as for instance up the incline toward one of the supporting towers not shown will cause an additional tension on tract-ion line 4 and a correspondingincrease in the gripping ability, on main cable'3, of our improved fall rope carrier. 7 In the arrangement illustrated in Fig. 3 but one gripper wheel 19 is shown and link 28 of tension wheel 26 is therefore pivoted at its lower end to frame 9 preferably at 23 In Fig. 4 a similar arrangement to that of Fig. 3 is shown, differing therefrom only in the length of arm 27 which length is increased to bring wheels 26 and 19 in sub- 7 stantially the same vertical plane whereby -,of wheel 13 by short links as 36. In this arrangement the downward pull of lines 4 and 5 tend to slightly counteract the upward pull of wheel 26'. To reverse this tendency we proceed according to the showing of Fig. 7 wherein links 21, 22 have oppositely extending ears 37, 38 wherein are pivoted at 39, 40 the upper ends of links 33, 34 respectively. By this arrangement downward pull on links 33,34 tends to force wheels 19, 20

upwardly.
