To til/3 7% it may concern cles and goods of various kinds, across rivers in places Where low level bridges cannot, for navigation purposes he used, or Where terry boats are not suitable, it is common to provide a transporter brie ge comprising an overhead girder carried by suspension chains supported by piers or standards and provided with a traveller from which is suspended. by means at ropes, a 'ilattorin, frame or cage to carry persons, vehicles, goods and so forth, the traveller being; traversed along the girder from one end thereof to the other by a motor mounted upon it, or by one or more ropes worked by a stationaiy engine at one side of the river. Transporter arrangements oi" this kind are necessarily very heavy, and are expensive to construct, erect, maintain and WOlhC and for this reason are impracticable in many places where a tansporter system is desirable.
'lransportmr suspension arrangements comprising a chain, cable orrope suspended lt'rom the upper ends ot a pair oi piers or standards at opposite sides ol a river and carrying a traveller that can be traversed :lron'i one end of the chain or ta uivalent (hereinafter re'lerred to generically as llexible suspension means) to the other by a rope or ropes and :lrom which a plat'l orn'i, Frame or cage (hereinafter referred to generically as a plat'lbrn'i) is suspei'uled by elunns, ropes or the like, aresometimes used for carrying;
of the flexible suspension means, in accordance with the varying gradient or curve of the suspension. member, soxtha-t it the plat form started and terminated its journeys at ordinary ground level, that is to say, withoutthe use of inclined approaches,
which are objectionable, it would, except at times of low tide, have to pass through the river. 'lonsequently, although such a suspension transporter arrangement is a coinparatively light structure and is much less costly to construct, erect, maintain and Work than the heavy rigid overhead transporter bridge arrangement first herein referred to, its use is limited to tidal rivers, and to certain periods of the day, for transporting only certain classes of goods and is quite in applicable, as heretofore constructed and operated, for use in cases Where it is desired that the starting and stopping places shall be at ordinary ground levels in order that heavy articles or bodies, for instance motor cars, lorries and other vehicles and loads, can be run on to the platform without having to raise them, and afterwards run ell the platform without having to lower them, or without having to provide inclined approaches to the starting and stoppii'ig phices, and Where the platform shall not, during its to and fro journeys, rise and :lall to any considerable extent-by reason ol'hthe SUSPQH" sion chain hanging in the term of a catenary.
Now the present invention has for its object so to adapt or construct a suspension transporter arrangement of the general hind referred to, that the platform shall be suspended lroni flexible suspension means in such a manner that during," its to and fro journeys across the river over which the arraiua ement ope ates, it will rise and fall only through a very small height so that the starting and stop iing places at the sides of the river can he at the ordinary ground level. of the banks oil? a navigable river across wliich passage is desired.
For attaining his object in a sus 'iension transporter arrangement according to the iirczezent invention, the flexible suspension means employed. is adapted to serve as a tie);- ihle rack and the movable platform. used. therewith is supported therefrom through supporting and traversing means coni n'isingg; a traveller (iereinatter callednthe controller) provided with mechanism adapted to gear with and be operated by the flexible suspension means when the controller is hauled or moved from one end thereof to the other, and compensating; lowering and raising mechanism, automatically operated or controlled from the controller mechanisn'i. and from which the platform is suspended by one or more depending rods, chains,
cables or the like (hereinafter called for brevity and distinction the sup porting chain or chains). The construction and operation of the said lowering and raising mechanism are such that although the controller will,
during its travel, rise and fall to an extent depending upon the versed side of the catenary curve of the flexible suspension means used, the point or points of support for the platform from the lowering; and raising; mechanism will fall and rise only to a very small extent so that the platform will travel in a nearly horizontal or in a slightly waved path.
To enable this result to be attained, the point or each point of connection of the supporting chain or each supporting,- chain, c ying the platform, to the lowering and raisingmechanism operated by the control ler, is so arranged and operated that it will raise the platform when the controller is de scending one portion of the flexible suspen sion means and will lower the platform when the controller is ascending the other curved portion of the said flexible suspension means, with the result that, in relation to a horizontal plane, the said point of connection will remain nearly level and at the same height during the whole journey of the traveller alon the catenary curve. The flexible suspension means may be provided with two controllers, each having a. point of suspension for a supporting chain as described. Also, in some cases the overhear. flexible suspension means may comprise two or more members arranged side by side and at a suitable distance apart and each provided with one or two controllers.
Theflexible supporting means may comprise one or more link chains. In order to provide flexible suspension means suit-aliile for the purpose set forth but of less wei; it than a link chain or chains, so as to admit of the invention beingmore readily and economically applied in the construction of suspension transporter arraiuremengs of the kind referred. to, of greater length or span, say of the order of magnitude of one thou sand feet and upwards, than can be done when one or more link chains are used. the
iiexible suspension means used may advan wheels when the controller is traversed over them. clonvenicntly, the. tceih may be formed, in one or more loim'itudinal sets on a large number of metal slccvcs arrang d end to end, and adapted to be suitably lixcd to the wire rope or ropes.
Nith a. view to preventing relatively cndways movement between the ropes and sleeves, due to tmnperature changes. these parts may advantag coiisly be formed, oli metal having the same co-clloicnt of expansion. Also, with a vie to reducing weight, the teeth may be made hollow.
In flexible suspension means constructed as just described, it will, be uiulcrshmd that as the wire rope or ropes is or arc. covered by the sleeves, it Or they will not be subjected to friction with the controllcr and will therefore have a long; life. .llso, as the rope or ropes will become coated with oily or greasy matter from the controller it or tbcy will not be subject to oxidation. .ilso, the sleeves can, when ncccssuuv. be easily r newed.
Or, in lieu of using one or more wirc ropes of round or substaniially round shapc in section. as the llliillllt suspentuou means for carrying); the rack or raclo-i. a. length ol liar wire rope may be used for c:u'r .in;r the racu or raclrs.
ll ith a suspension transporter :uruiu w ment according to this invention. the :ut vantages of an overhead var-pension tl'iiliH- porter bridge, namely, that it a light :-:lructure, cheap to construct, erect, maintain and work in comparison with the heavv rigid overhead transporter bridge arrangement commonly used. and is safe and i'clicblc in operation. can be obtained without the di :ulvantzrn'cs of the known couslruciimis of overhead suspension tralr portcr bridc'cr: :13 heretofore constructed and operated.
Overhead suspension transporter bridge arrangements accordiiur to the invention, and. :ulapted to act in the manner set. forth. can be constructed in various forms.

Fig. 5 shows in vertical section and Fig. 6 in side elevation. portions of the lowering and raising mechanism shown in Fig" 2.
Fin. 7 is a cross section on the line of Fig. 8 and Fin. 8 is a cross section on the line D l) of Fig. 7, showing a n'lodilied arrangement in which the flexible suspension means comprises a wire rope with sleeves llG and two sets of teeth forming flexible racks. Fig. 9 shows in side view, a modification of the arrangement shown in Figs. 7 and 8.
Figs. 10, 11 and 12 are similar views to Figs. 2, 3 and 4: respectively but showing flexible suspension means comprising two wire ropes with sleeves and a single flexible rack. Figs. 13 and 14: show the two ropes and associated parts in cross section and longitudinal section respectively and to a larger scale than Figs. 10, 11 and 12. Figs. 15 and 16 show in cross section modified constructions of flexible suspension means. Figs. 1'7 and 18 show in cross section and side elevation, a further modified construction of such suspension means. Figs. 19, 20 and 21 are diagrammatic views showing further modified arrangements hereinafter more particularly described.
According 1301 the example shown in Figs. 1 to 5 inclusive, the flexible suspension means comprises a chain 0, carried by the upper ends of a pair of openwork piers, standards or trestles Z2 and c suitably supported. at opposite sides of a river A, the chain being composed of links or plates and pins forming what is known as a pitch chain. The ends of the chain rest on the piers, standards or trestles, and are securedby stays or guys d that extend downward at an angle to the ground to which they are anchored in the usual way.
Associated with the suspension chain a is a controller with hoisting and lowering mechanism, marked collectively e in Fig. 1, from a point of which are suspended links 7" and chains or wires f for use in carrying a platform 9 below. The controller is provided at its upper part with two transversely arranged driving shafts h each provided at its central portion, between two bearings '21, 2' with a chain or sprocket wheel 71: adapted to gear with and be operated by the suspension chain a; when the controller moves over it. To each of the outer ends of each of the driving shafts 72. is fixed a toothed. wheel m that gears with and drives anotherand larger toothed wheel a fixed to the outer end of a short transverse counter shaft 0, the two counter shafts being mounted in hearings in the controller frame r below the shafts h.
For the purpose of relieving the shafts 7i and sprocket wheels of part of the weight of the controller and the parts suspended therefrom, there may, as in the example shown, be arranged. between the sprocket wheels is, an idle sprocket wheel 3 mounted to turn about a shaft 6 and to gear with the suspension chain a, the bearings a for the shaft t and wheel 3 being made vertically adjustable, as for example under the control of screws 10 so that the wheel can be adjusted and set to take a considerable amount of weight off the sprocket wheels is.
The two counter shafts 0 are arranged coaxially with a space between their inner and adjacent ends. To the inner end of each of these countershafts is fixed a chain or sprocket wheel 1 over and with which works a freely dependent chain to, that may conveniently be an endless chain, though it may be an open ended chain having its free ends extending downward. W hen an open ended chain is used, a receptacle can be suspended from the controller frame to receive the free ends of the chain. Connected to the two freely dependent chains, say at the centre of their lengths, is a transverse supporting or suspension pin 1 (hereinafter called the supporting pin) which couples the two chains together with a space of a few inches between the two chains. To the central portion of this supporting pin is revolvably connected, in the manner shown in F L and 5, the supporting links f, or chains, used for carrying the platform 9 below. The pin 1 is preferably made of the form shown in Fig. 5, large in diameter, and with a large central portion to withstand the bending strain to which it is subjected. The means used for attaching the links 7 to the pin 1 are alsoenlarged to afford. sufficient strength to ensure an effective connection. In the example, the links are jointed to a strong link 3 that encircles and is seated upon the pin 1. through the intermediary of a renewable bearing 3. The central portion of the pin 1 and the corresponding bearing portion of the link 3, or bearing 3 are preferably made of spherical shape as shown to allow for any slight inequality of wear in the two supporting chains w to which the pin is connected.
Suitably shaped and arranged guards may be associated with the ch ain or sprocket wheels 4) and chains w to prevent any possibility of their getting out of gear with one another. In the example. this is provided for by the constri'iction of the controller frame r, as will be seen from l igs. it and 8. r is a guard fixed, to the frame 1- to prevent the chain It coming out of 'gear with the sprocket wheels Z: and in the arrange ment shown, the lower ends of the links 7 are connected through pairs of splayed or diverging bars or wire ropes f to the plat form 9 near to opposite ends thereof.
The controller 6 and with it the platform 9 may be hauled to and fro along the suspensionchain a by a rope a that extends from the winding drum of a reversible winding engine a arranged. at one side of the river, conveniently on a raised part of the standard 6, over thecontrollcr e, to which it is suitably connected at (a around a sheave a carried by the other standard 0 and thence back over the suspension chain, controller and first standard to the winding drum of the engine. The arrangement is such'that when the controller 6 is hauled by the rope a in one direction from its starting posi tion, it will descend one curved end portion of the suspension chain a and its sprocket wheels 70 will be rotated by the suspension chain, and the two adjacent freely dependent chains to will be simultaneously operated in a direction to raise the supporting pin 1 between them so as to maintain the platform in such a position that it will, in relation to a stationary horizontal plane, remain nearly at the same height, this action continuing until the controller reaches the central and lowest part of the suspension chain, at which time the pin 1 will reach the highest part of its travel in relation to the pair of wheels '0 over which the chains w, to which it is connected, pass. As the controller commences to ascend the opposite upwardly curved portion of the suspension chain a, the pin 1 will, in turn, commence to descend on the opposite side of the pair of chain or sprocket wheels '0, but in such a manner in relation to a stationary horizontal plane, that it will remain at approximately the same height, this action continuing until the controller reaches the end of its forward journey. Upon the controller making its return journey. the direction of operating the gearing will be reversed and the above described operations of the pin 1 repeated, but the pin and other mechanism will then move in the reverse direction. WVith the arrangement described, the platform will move in a curved path that extends slightly downward from each end and then curves slightly upward to the central portion of the path which is ofupwardly convex form.
as shown by the line a; in Fig. l, the platform 9' being at the same height, from a horizontal plane, when at each end of its travel and also at the centre of its travel.
Figs. '7 and 8 show an arrangement wherein the flexible suspension means instead of consisting of a link chain. as hereinbetore described. comprises a single steel wire rope 5 of circular section provided along its length with a number of metal sleeves, arranged end to end and adapted to be securely fixed to the rope, the sleeves being provided along their length with teeth adapted to gear with the teeth of gear wheels on the controller. In the example shown, each sleeve is divided horizontally into two parts 6 and 7 formed of sheet metal. The upper part 6 is bentor shaped, as between dies. to form a central concave portion fitting over the rope. and two side portions each of which is shaped to form a row of teeth 8 or 8. The central portion of the lower part 7 of each sleeve is also bent or shaped as shown. to form a central portion fitting the underside of the rope, and two side portions that are slotted to form rows of fingers 7 that are bent over the side por lions of the upper part of the sleeve and lil into the recesses betwcen the icclh :s so as to tightly clamp the said sidc portions of the upper part oi the sleeve lo the lower part thereof at these points.
Each sha lt /i (l ig's. 2 and 3) ot the controller has fixed to it two toothed wheels 7.: a (see Fig. 7), to gear with the two rows of teeth 8, 8 and carries an intermediate grooved wheel 9 arranged to run on the central convex upper surface ol the sleeves 6, 7 so as to relieve the toothed whccls Z ot the w ight of the controller and its load. The joints 10 between adjacent lowcr portions 7 ot the sleeves may coincide with the joints 11 between the adjacent upper portions (3 ot' the sleeves. as shown in Fig, 8; or the two sets of joints may be staggered. llhe joints between the adjacent upper portions (3 of the divided sleeves may be arranged to be slightly open so as to permit the sleeves to move angularly with l'cl'er ence to one another to compensate for the varying curvature or movement of the flexible rack as a whole when the conlrollcr with the load is being moved along such rack.
Fig. 9 shows sleeves similar to those shown in Figs. 7 and s but each mode in two parts of cast metal connected together by bolts i" and nuts 7 Instead o'l using a single wire rope. to form the flexible suspension means. two. three or more wire ropes may be used. grouped in any desired way and connected together sideways by the sleeves. which are. adapted to suit.
Figs. 10 to ll inclusive show a suspension transporter arrangement in which the flexible suspension means comprises two wire ropes 5 arranged side by side. ln this example. double sleeves l2. 1E2 are adapted to be fixed. to the two ropes and carry bctween them a row of teeth 13. such double sleeves with intermediate teeth bciu I'ormed out of a piece oi" sheet metal which is pressed or stamped between dies to form the row o'l teeth l3 and curved side. porlions lo il'orm the sleeves 12. 115 which. al'lcr being placed on the ropes. are bent around the same so as to become tightly chnnpod thereto (see Fig. 13). To facilitate the bending: of the edge portions oi the piece of metal around the ropes they are slotted to jl orm lingers 12' that can be readily bent to the shape shown. .ln this case each of the shafts 72 ot the controller has fixed to it a toothed wheel Z: to {Jfear with the row of teeth 13 carried by the successive double sleeves l2. l2 and is provided with two grooved siuiportinp wheels 9. f) arrang'ged to run on the convex upper portions o. the successive double sleeves i2. .12". The vcrtically adjustable intermediate shaft 2 ol the controller (Figs. 1] and 12) is also llll iaraoro controller shown in Figs. 10 to 14 inolusive corresponds to that shown in Figs. 1 to 6 hereinbetore described and it acts in the same way as that controller.
To facilitate quick and accurate assembly of the sleeves on the rope or ropes with the teeth in the longitudinal set thereof, or each longitudinal set thereof, in a row or rows, so that they will gear in an efficient manner with the gear wheels 70, or 72 on the controller, their adjacent ends may, as shown for example in Fig. 12, be provided with corresponding inter-engaging projections 1st and recesses 15 that ensure theirbemg placed 1n the correct relative positions around the rope. The inter-engaging projections 14 and recesses 15 also serve to keep the several sleeves in line and to preserve, as far as possible, an unbroken wheel track, that is to say a track in which there is not a straight transverse line of division between the upper portions of adjacent sleeves. The sleeves are held firmly against each other by larger sleeves 15 (see Fig. 12) rigidly fined to theend portions of the wire rope or ropes near to the points of suspension of the rope or ropes from the sup-porting standards I), 0 (Fig. 1).
l In order that the teeth shall gear in an ellicient manner with the toothed wheels on the controller, they may advantageously be so termed and arranged, as shown in Figs. 7, 8, 13 and 14," that the pitch lines of each set thereof correspond in position, as seen in side view, with the longitudinal axis of the wire rope 5, or ropes 5, 5*, so that the relative position oi: the teeth will not be materially atlected when in position for use. When three ropes are used, as in the example shown in Fig. 15, one, namely 5, may be arranged centrally above the other two 5, 5 and each sleeve may be. composed of an upper portion 6 adapted to extend over the upper rope and down over the sides of the two lower ropes, and a lower portion 7 adapted tolit the underside oi the two lower rope and to be connected to the upper portion oi the sleeve in either ol': the ways hereinbetore described. The upper portion oi the sleeve may be provided, at opposite sides thereof, with rows oi: teeth 8, 8 and with an intermediate flat or convex track portion 8. the pitch lines of the teeth being well below the top of the composite rope. In the case or tour ropes, they may be arranged in two superposed pairs. as shown in Fig. 16, with the sleeves 6-7 adapted to surround them, and provided with two rows of teeth 8, 8
" Figs. 17 and 18 show flexible suspension means comprising a flat wire rope 18, provided with sheet metal sleeves having racks 5?, 8" and an intermediate bearing surface constructed. and applied as hereinbefore described with reference to Figs. 7 and 8.
Flexible racks such as described although speei ally advantageous for suspension transporter arrangements of long span, can of course advantageously be used for relatively short spans. Also, they are applicable for use in any case where a flexible gear chain or rack has been required, or is required, for driving purposes. Eiuch flexible racks will form the subject Off a separate application for Letters Patent.
Instead of using a single controller 0 with compensating raising and lowering mechanism, as hereinbetore described, two such controllers may be used, on the flexible sus pension member a, as shown in Fig.19, the said controllers being connected together at a suitably fixed distance apart, as by a distance member 6 so as to form two points 1 of suspension for two sets of links, chains or wire ropes 7', f for use in supporting a With such. an arrangement, the two controllers will reach the lowest part. of the suspension member a, one after the other. As the angle of descent on starting from either end slightly exceeds the compensating upward motion imparted by the controllers, such slight variation in the level of the platform 9 that might result from this arrangement, can be reduced by arranging the points 7 oi connection oi. the supporting chains or wires f to the platform at a greater distance apart longitudinally than the distance between the centres of the two transverse supporting pins 1 on the two controllers, that is to say, between the centres of the two controllers.
When two or more suspension members a are used, each suspension member may be provided with one controller, or with two controllers, there being say two sets of supporting links or chains f in the one case and tour or more supporting links or chains in the other, tor carrying the platform g be low, with the aid it may be, of pairs of splayed. or diverging chains or wire ropes f between the lower ends of the supporting links or chainsand the ilat'liorin. .llig. 20 shows two suspension members (L each provided with two controllers iln each of these cases the two controllers in the one case, and the tour or more controllers in the other, would be suitably braced together by connections 0 in order to maintain them 111 correct relative positions. Also, in each of these cases the hauling rope a may be attached to a connection a midway between the pair or pairs of controllers. Or a separate hauling rope could be used with each suspension member and. the controller or controllers thereon. Such arrangements will be readily understood from the forego ing description without the aid of additional drawings.
The controller or controllers instead of being hauled across the suspension chain or chains by a rope, may be fitted for instance with an electric motor 2st (Fig. 21) and driven by electric energy supplied through a cable 25 from an electric generator 26 on one of the banks of the river.
With a transporter suspension arrangement constructed and operating as hcreinbefore described, the starting and stopping or landing; places for the platform can be arranged at the ordinary ground level on the banks of a river, so that vehicles and other loads can readily pass on to and from the platform and, if necessary, an upper platform 9 (Fig. 19) may be provided for passengers, which may be reached by stairs extending upward from the lower platform, or by stairs arranged at each of the landing places at opposite sides of the river.
The load carrying means, herein called a platform, can of course be constructed in. various forms. For heavy traffic it may consist of a long box-like structure resembling a railway vehicle without wheels, that may be divided up vertically or horizontally, or both vertically and horizontally, into compartments or floors to receive and hold vehicles, goods and so forth and to accommodate passengers. Or the platform may be of square or other convenient form.
It will be obvious that transporter suspension arrangements such as herein described may, with advantage be constructed and used for carrying passengers, vehicles and goods across valleys, ravines and the like where other means of transport present much ditliculty, and such use is contemplated and intended to be covered by the present invention.
The details of construction of transporter suspension arrangements according; to the invention can be variously modified.
