AERIAL ROPE TRAMWAY.

SPECIFICATION forming part of Letters Patent No. 534,316, dated February 19, 1895.

Application filed August 9, 1894.

To a/ZZ whom it may concern.-

Be it known that I, SEBERN A. CooNEY, a citizen of the 'United States of America, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Aerial Rope Tramways, of which the following is a specification.

The present improvements relate generally to cable tramways, but more particularly to aerial rope ways wherein the trolley with its suspended bucket or load is supported by and travels along a ropeway stretched between distant points, and is propelled along such ropeway by a motor cable having some attachment to the trolley or its frame.

The invention has for its object to provide exceedingly simple and effective means for gripping the motor cable to the trolley or car and also to provide in connection therewith means for causing the automatic gripping and releasing of the motor cable.

With these ends in view the improvements consist in the novel structure, arrangement and combinations of parts hereinafter fully set forth.

To aid a more ready understanding of the invention a detailed description of a practical embodiment thereof vwill now be given in. connection with the accompanying drawings, in which- Figure 1 is a front elevation of a portion of an aerialitramway and a trolley and its suspended bucket and the motor cable with full and dotted lines indicating the positions of the automatic grip operating devices relative to the grip on the trolley or its framing. Fig. 2 is an end elevation thereof, the rope of the tramway and the motor cable being vin section, and one of the rigid supports for the ropeway usually located at the termini; the automatic grip operating devices being indicated by full and dotted lines. Fig. 3 is an enlarged front elevation of a motor cable grip or gripping device with the contiguous portion of the trolley frame. Fig. 4 is a vertical transverse section .taken on the line 4, 4, of Fig. 3. Fig. 5 is a sectional detail on the line 5, 5, of Fig. 4; and Fig. 6 is a like detail on the line 6, of Fig. 4.

The invention now to be particularly described while particularly applicable to an Serial No. 519,899. (No model.)

will be described in connection therewith,l

may obviously be applied to and employed in other forms of tram or railways, and with cars, trucks or trolleys other than those especially adapted for aerial ways, and hence it is to be understood is .not necessarily limited in its useful applications to the precise structures herein shown and described.

As shown, the trolley A, per se, consists of the usual pair of grooved truck-wheels a., supported and connected together by a pair of side plates a', which Wheels are arranged to travel along a track in this instance provided by a properly stretched ropeway B supported a distance above the ground in any of the Well known modes notpnecessary to mention here. The bucket or other carrying .frame b is of A-shape of flat bar iron pivoted at its upper end on a pivot b fixed to the trolley side frames of and at its lower ends isformed with hooks b2 which carry the bucket b3 suspended between them. Intermediate of its upper and lower ends the frame bis provided with an open cross frame b4 of iiat bar iron riveted to the opposite vvertical legs of the frame, such cross frame approaching diamond form with attened corners; andvvertically and midway of the cross frame is riveted or otherwise secured a grip carrying plate b5.

The carrying plate b5, see Fig.4, is provided with a bearing c for the horizontal spindle c of a grip Wheel d forming one member of the gripping device C, and with a pair of bearings efor a transverse screw shaft f having connection with the grip shoe g forming tne other member of the gripping device C, said gripmembers being adapted to coact to grip a motor cable D. y

f The bearing c for the spindle c is slightly elongated, see Fig. 5, so that the spindle with the grip wheel d may be adj usted vertically by a set screw h; and the spindleis flattened on its opposite'sides to lit said bearing without turning and so as to form a shoulder c2 for contact with one side of the bearing; the opposite end of the spindle having a nut c3 to secure the spindle in place after each vertical adjustment. The spindle projects outward from the bearing to the front of the carrying plate b5 and forms a support for ICO the grip wheel d whic his loosely journaled thereon and is confined between the bearing c and a head on the spindle c.

The grip wheel d is arranged to underlie the motor cable D to take its weight and to oppose and counteract the thrust of the grip shoe g when gripping the cable and also when the grip is open to rotate loosely against the underside of the motor cable. Said wheel in the main is formed with a straight slightly conical circumferential flange with a shallow central recess d for the cable, as is seen in Fig. Il.

The grip shoe gis formed by a longitudinal horizontally arranged block having in its under surface a gripping recess or groove g to take over the motor cable and curved to correspond with an arc of a circle concentric with the grip wheel CZ so that in gripping the cable, the latter will be bent over the top surface of the grip wheel CZ and thus the gripping surface and power of the grip are materially increased, as is indicated in Figs. 1 and 3. The grip-shoe or block g is arranged to be adjusted toward and from the grip wheel d, and for this purpose is carried or formed integral with the short arm of a bell crank t that is mounted in a vertical recess in the carrying plate if on across stud or rod t. The upper end of the long arm of the bell crank fr', is bifurcated, see Fig. 6, to receive a nut f traveling on the screw rodf, and the opposite limbs of the bifurcation are provided with the slot t2 to engage studs or projections f2 extending from the opposite sides of the nut so that the movement of the nut is communicated to the bell crank and causes it to rock on its pivot to move the grip shoe into or from gripping action.

The screw shaftf may be rotated in any suitable manner either by hand or power or automatically by the travel of the car or trolley with which the gripping device is used. In the present embodiment of the invention, the screw shaft f has secured to it a plain Iianged wheel or pulley k, through which the screw shaft maybe rotated.

The means foi` automatically opening and closing the grip members in the present case are arranged parallel with the line of movement of the trolley along the rope tramway so that the grip is operated in the travelor movenient of the trolley. Thus at or near one end of the tramway there is properly supported a longitudinally arranged bar, beam or timber E adapted to be borne upon along its under side by the wheel 7.a of the gripping device C in the movement of the trolley so that such wheel shall be rotated to rock the bell-crank t' and close the grip-shoe g in firm gripping contact with the cable on the grip wheel (l. At or :near the other end of the tramway another longitudinally arranged bar, beam or timber F is supported that is adapted to be borne upon along its upper surface by said wheel 7i: in the travel of the trolley whereby said wheel is rotated to rock the bell crankt and remove the grip shoe g from gripping contact with the cable.

The surface of the operating wheel 7.: or the surfaces of the closing and releasing bars E, F, may be faced with some friction-increasing material; such as soft rubber or the like, to better insure the wheel t being rotated when traveling in contact with said bars.

In Fig. 2 is shown a rigid supporting shoe G firmly bolted to a beam G', such shoe serving as a support for the rope forming the ropeway to hold it rigid at the termini of the way, as is usual in such structures.
