Specification of Letters Patent.

Application filed. May 16, 1906. Serial No. 317,103.

To all whom t may concern:

Be it known that I, ALMON E. Norms, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Hoisting or Conveying Apparatus, of which the following description,

in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My invention relates to hoisting or conveying apparatus, being more particularly though not exclusively concerned with cableway apparatus and the provision of a new and improved system of fall rope carriers for such apparatus.

My invention will be best understood by reference to the following description thereof, when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the d1'awings,-Figure l shows the trolley carriage and an assemblage of the principal features of the'fall rope carrier system in a hoisting and conveying cable-v way apparatus embodying one form of my invention; Fig. 2 shows in side elevation an enlarged viewr of a main carrier trolley and carrier frame of the construction shown in Fig. l, together with its relation to the several ropes of the system; Fig. 3 shows the saine in front elevation, partially in section; Fig. 4 shows a portion of a cable-way with the trolley near the end of its travel and the carriers separated by their full distance, Fig. 5 shows the opposite end of the cableway with the trolley carriage near its starting point of travel, and Fig. 6 shows the cable-way partially broken away with the trolley carriage at an intermediate point.

Referring to the drawings, I have shown my invention by way of illustration as embodied in a cable-way apparatus employing as the hoisting and conveying unit a grab hoist A, which is supported from and operated through the medium of an overhead trolley carriage B, the latter mounted to travel along the cable-way a. The specific construction of the grab hoist forms no essential part of my invention and the same is shown herein merely as a conventional representation of any trolley-supported unit, it being understood that my invention is applicable to various constructions of cableway and other apparatus without reference to the hoisting unit employed.

The particular construction of the trolley and the number, arrangement or purpose of the various operating or other ropes employed is not essential to my invention, but in the illustrated embodiment thereof l have shown the trolley B, adapted for travel along the cable-way a under the control of an endless traversing rope o. As is usual in this class of apparatus, one end of the traversing rope o is attached to the trolley carriage B, and, after passing over a shea-ve Z on the tower X at the farther end otl the cable-way (Figs. t and 6) leads back in the return strand o longitudinally throi'lgh the trolley and to and over a sheave d upon the tower Y at the opposite end of the cableway and thence down toand about a :suitably driven and controlled rope drum c. The other end c2 of the traversing rope is attached to the opposite end of the trolley carriage and, after leading to the tower Y, passes over a suitable sheave down to the rope-winding drum c, the traversing rope thereby constituting in effect an endless rope controlling the travel of the trolley carriage according to the rotation of the ropewinding drum c.

In the present instance the grab hoist is controlled both for hoisting and for opening and closing by means of a single rope f. My invention is not limited to, nor essentially concerned with its application to tems employing but a single hoist-operatin rope, but the illustrative embodiment thereof will suiiiciently suggest its application to other systems and to thosev employing a plurality of ropes for controlling the hoisting unit. This hoist-controlling rope f is connected to the trolley carriage at f, and, after passing downward to the hoist over and about suitable sheaves thereon, leads up to and over the guide sheave f2 carried by the trolley, thence to a guide sheave upon the operating tower Y and down to and about a suitable rope-winding drum at the base thereof.

As is well understood in the art, the operating rope f requires distributed support through fall rope carriers or the like when the trolley is moved to a distance from the operating tower, and one of the objects of this invention is to provide such support in a simple but eifective way and under such conditions that danger of entanglement or ioo interference between the various parts constituting the fall rope carrier system is reduced to a minimum.

Referring now more particularly to Figs. l, 2 and 3, the operating rope f is given its additional and distributed support through the means of the separate main rope-carrying units or carriers g. These consist (Figs. 2 and 3) each of a carrier trolley frame comprising end plates g riveted to the flanged side plates g2, the latter vcarrying a bearing pin g3, upon which is journaled the carrier trolley Wheel g4, adapted to travel along the cable-way a and to transmit thereto the weight sustained by the depending carrier. This carrier frame is riveted to an elongated upright frame L, which depends from the carrier trolley frame and furnishes journaled support for one or more sheaves which are suitably positioned and arranged to sustain or assist in sustaining the weight of one or more of the operating ropes. At one side of the frame the returning strand c of the traversing rope engages with and is supported by a sheave It', the latter given suitable ournaled support between the side of the frame h and the overlying plate h2 riveted thereto. At the opposite side of the frame and somewhat below the level of the sheave L, is a second supporting sheave h3 journaled upon a pin sustained by the frame h and a plate h4 which is riveted to the frame. This sheave engages with and assists in sustaining the hoist-operating rope f.

AStill farther down near the lower part of the frame and journaled between the adjacent walls of the frame is a third sheave 7L, which underlies and assists in sustaining the other strand c2 of the traversing rope. Thus it will be seen that each carrier, supported directly as it is upon the cable-way offers support not only to the hoist-operating rope f but to the two strands c and c2 of the traversing rope as well.

Referring now to Fig. l, it will be seen that the Jforemost carrier unit g, or that next adjacent the main trolley carriage B, has

rigid attachment thereto, being connected at either side (front and rear end Fig. l) y through a pair of angle irons I7', which are each jointed or swiveled at one end to the trolley and at the opposite end to the carrier frame, so that the foremost carrier while permitted a certain flexibility of movement relative tothe carriage as is necessary for use upon the cable-way is rigidly connected thereto so as to be pushed or pulled thereby at a fixed Vdistance therefrom. As the trolley moves in one direction or the other the foremost carrier follows or precedes it. as the case may be, at a fixed distance predetermined by the rigid attaching frame. The end or transverse plates g of each carrier trolley frame form abutting or striking plates, which, when the carriers close in on each other', contact each with the adjacent end plate of the next adjacent carrier, so that when the trolley is near the operating tower or its starting point, as represented in Fig. 5, each carrier frame abuts against its neighbor` and the same are positively spaced near their upper portions by a distance equal to the length of the carrier trolley frame. As the trolley carriage is moved toward the operating tower Y from a distant position, where the carriers have been separated at intervals, as represented in Fig. 6, the carriers are overtaken one by one, each by its neighbor, as the latter itself is advanced by the foremost carrier and the intermediate abutting carriers, until they linally assume the closed-in position shown in Fig. 5. The strand el of the traversing rope is connected with the carriage by being secured at l7" to a transverse bar or member connecting the two lower members j of the rigid frame connection.

In order to distribute the supporting carriers uniformly as the trolley is moved toward the farther end of the cable-way, it is usual to provide some kind of distance or separating devices, those usually employed being some kind of unsupported flexible connections directly connecting the carriers themselves. Such connections, however, have usually been quite susceptible of entanglement, and to prevent the unsupported length of these flexible connections from being excessive, moreover, it has been necessary to reduce the interval between the carriers by increasing their number beyond what is actually necessary to afford effective support to the operating ropes. In the illustrated embodiment of my invention l have provided between the main carrying units, distancing means, which are free from danger of entanglement and act to separate or locate the carriers when extended at a predetermined distance interval. These are so arranged and constructed as to receive support between the main carrying units, perf mit-ting the selection of as great an interval between the extended carriers as may be desired. For this purpose any suitable means may be provided but there are here provided between the respective carrying units distance members consisting of spacing links K, K (Fig. l) which may be constructed in any suitable fashion and formed of any suitable material, but which preferably are light metal rods of suflicient size and shape to afford a certain degree of stiffness in order to prevent entanglement. These separating links are formed in pairs, the individual members of which, lc, r, respectively, differ principally in their mode of attachment at their lower ends. The link f: is provided with an elongated fiat eye 72, and the link 7c with a short but bent or inclined eye 7c3 formed at right angles to the eye k2, but

coupled therewith. This connection, as will be evident trom the description to follow, permits a certain tree endwise play between the two rods and, when the carriers separate, allows the rods to become partially opened or separated without that resistance which is interposed when one rod begins to litt the other. This connection practically eliminates the danger ot the rods in any way entangling or fouling each other during separating or closing movement of the carriers.

Each link receives overhead support from a carrying element of some kind. Starting with the end link of each series, as for eX- ample the link 7,1 shown in Fig. Q, the same is secured to the lower end of the main carrying unit, being provided for that purpose with an eye 71:4, which is linked to a shackle u", the latter swiveled to swing about a lower corner of the carrier frame 7L. The next adjacent link 7., to which it is coupled at its lower end, is `jointed at its upper end through a similar shackle connection to a link-carrying trolley Z, the latter consisting merely ot a simple sheet metal frame ot general upright rectangular outline, as viewed in side elevation, provided with thertrolley wheel Z through which it is sustained upon the strand c2 ot' the traversing rope. Each link or rod carrier has as its lower end a pair of shackles, to one ot which is attached the link 7c, as already described, and to the other of which is attached a link v, the latter having a construction at its lower end adapted to mate or couple with an adjacent link (Fig. l), sustained by an adjacent linkcarrying trolley. In this fashion there is provided a series of jointed separating linked pairs, the members of each pair being sustained upon adjacent link-carrying trolleys. This series of intermediate trolley supported links is jointed at each end to a main carrier by means of the main-carriersupported link described, the latter dit'fering from the other corresponding links of the series only by a slight difference in length. It will be obvious that when the carriers are separated these links are caused to separate or open by the separation of their trolley carriers, permitting a separation between the main carriers of approximately the aggregate length ot the links, as will be clear from Figs. a and G. .Vhen closed (Fig. they hang freely and without interference, as shown in Fig. l. The end link of the entire system may be attached or anchored to any stationary object, as the structure ot thetower Y.

lu the embodiment of my invention illustrated in the drawings, the cable-way is assumed to have a length et approximately 'T00 feet and with the number and length of separating links is suliicient to permit a span or interval between the carriers when fully separated ot approximately 100 feet,

the linked separating members, however, being adequately supported at intermediate intervals oit' approximately 2O feet. It will be understood that these figures are given merely as illustrative of advantages which follow from the use of this invention, the lat-ter being in nowise limited to dimensional or constructional details or the number ot spacing members employed. v

The link-carrying trolleys when the carriers are separated are supported upon the strand. c2 of the traversing rope,but the latter receiving' support from each carrier the weight of the links and connections is sustained directly upon the cable-way. This is a simple and convenient arrangement but it will be obvious that the intermediate support may be derived directly 'from the main cable a, as by mounting the link or carriers directly thereon or from other of the strands or cables thanv that shown. ln either case, however, it will be noted that the intermediate trolley carriers receive their ultimate support, whether directly or indirectly from the main cable c.

In the closed position ot' the carriers, as shown in Fig. l, the upright rectilinear ends of the link-carrying trolley trames come into abutting contact each with the other, the end members of the series similarly abutting with the corresponding and alining edges of the adjacent carrier frames t. The longitudinal dimensions ot' the link-carrying trolley frames are such that they act as spacers between the lower portions of the carrier frames, separating the latter along the traversing strand c2 by substantially the same distance that they are separated along the cable-way a. This construction, it will be seen, tends to maintain the carriers in a substantially upright position when closed in on each other and iirmly positions them `relatively to each other in fixed relation,

uite eliminatin0` an tendenc toward longitudinal rocking or displacement, leaving them in effect as separate but positively positioned and connected members of a supporting structure, and practically eliminating any possibility of interference or entanglement between their linked connections.

lVhile I have used the term rope 7 in referring to the cable and the various operating ropes of the system, it is to be understood that this term is used in a generic sense and to include other flexible power transmission devices, such as chains, wire cables, or the like, or other devices having like or equivalent functions.

lVhile I have shown and described in detail one practical embodiment of my invention, it is to be understood that the latter is not limited either to the application thereof herein shown, or to the form, details or relative arrangement of parts herein employed,

`but that extensive deviations may be made without departing from the spirit of the invention.
