'TRACK 'FoR memspsni) SUSPENSION RAILWAYS.

Application filed 'January 24, 1925,Se'al No."4,568, and in Germany'February-G, 1924.*

The invention concerns ahigh speed suspension railway for suspension cars travelling with very. great velocity about 20O`-300 M. P. H. on a single'rail `:and particularly the Construction 'and arran ement of the per -nanent way for this `ralway. .Further the invention is concerned with the details of the supporting means and also the'construction works and steel work on which the railsupports are fixed;

The rail itself must, in this invention 'be protected against variations of temperature, for example housediina tunnel-or tube or constructed of a material whiclris'in-itself as far as possible inditferent to temperature changes such as Invar whose expansiom.

coefiicient for'temperature is so small as. .=to. be practically negligible. 'Sinceall shocks on 1 the car must be avoided at this high speed the rail must' have throughout its whole length an absolutely smooth surface' and must be made of a material which will Iot rust and which'is unaffected by atmospheric influences. Unevennesses or joint-spaces which are present in the ordinary railway would at the great speed have `a serious elt'ect not only on the rail 'but also onthe ns prung parts of the running-gears of the cars. Since small iuequalitiesof-'the track are in practice 'unavoidable the'rail must` he supported in an elastic manner. and at the same time those portions of the track which must give heneath the weight of the car must he kept as light as possible; thatir' the rail itself and the pa rts immediately adjuceut which must givcsutlicieutly quickly under the shock. Those unavoidably heavy parts such as the adjustment-arrangement for the rail brackets may advantageously be transferred to points which give very little in the elastie movements of the system. The reason for this is that the inertia of an oscillating mass as is well known'is dependent on the product of the mass and the square of its velocity.

Since the jointless rail of temperature-indilferent material remains Suspended withont any appreciable expansion or contraction the girderwork being ofordinary material must be construeted in such a nanner as to be free to expand and contract independently of the rail. To this end are araranged iu this invention supports which hy hinging and bending allow the girdcrwork to expand independently of the rail not only without introducing serious stresses but 'which :are able to give' vertically in an elastienanner. v i

Our invention is :illust-rated diagrammatieallyan'd by way of example'in the accompanyng drawings in which: v

Fig. 1 shows in elevation and Fig. 2 in plan a diagrammatie example of the git-derwork system for the supporting of the raiL Both rails 1 are fastened to the girderwork 2 by means of a t'riangulated projection consi'sting of the arms 3 and 4:. Atcboth ends of the arms 3 and 4 hinges 5 are introduced. The girderwork 2 is carried on colunns (i which rest on hiuged beariugs 8 on the the above pur- 13- illustrate's-xan' adjustable rail greater the distance" apart of'the bearerarns-,'the"greater must be the weight of the rail and vice-versa. Therefore'there must be in this construction' 'one particular ar- -angementwhich -is the=most favorable. To `=this end one may reduce the weight of the bearer-arm of Fig. 6' by making it of such a section a's'to have' a constant'bendingresistanee the section in consequence varying intproportionto the length; In this way 'its mass-center approaches still nearer to the supporting girder-work so that the mass to be moved is reduced still further; A further' reduction of the' mass of the bearerarm can' be' etfected by using material with a must be mounted 'on the previously con-* structed -g'irderwork the bearer-arms inter'- posed must be such as to permit the exact' alig'nment of the rail. A 'similar alignr'nent 'is necessary at the curves and inthe transition from the straight trackfiln order that in sucha transitionno violent increase of centrifugal force of the car shall take plate at the high speed the curves must be made according to certain definite laws andbe laid quite smoothly. For this purpose in this invention an arrangement (see' Figs. 13 to 16) is provided which makes possible the exact alignment of the rail both vertically and horizontally.

On the gussetplate 31 (see F ig.' 13), which is fastened to the heurer-arm is arranged the rail-bracket 32 in a nanner that it is vertically adjustable while for horizontal adjustme'nt the side plates 33 are provided. In either movable part namely the rail-bracket 32 and the sideplates'33 the usual boltholes are 'replaced by larger oval slots 37 and 37, respectivcly in which engage projections of the plates 38 and 38* respectively. The latter are. iu the regions of the projections. provided with holes 35 and 35 in which the t'astening bolts fit Very exactly. The series ot looking plates with the bolt-holes drilled in different positions is stoeked in a systematic assortment. In fitting the rail-holders 32 those locking-plates are chosen in which the holes 35 and 35 correspond exactly with the holes 38 and 38 in the gussetplates 31 when the rail has been correctly aligned. Thus by the looking-plates and in particular the arrangement of the holes drilled in them any desired adjustment of the rail 1 relative to the girderwork can he ohtained. When the looking-plates with their projections are engaged in the slots in the rail-lolders and the bolts are passed through the holes and bolted up, the adjustnent of the rail is rendered permanent. Of

course the function of the oval slots and projections can be performed in other ways such as 'circular pro-jections and eccentrically drilled bolt-holes. For the tinest adjustnents of the rail a special arrangement shown in F i 14 is provided resembling a pair of divic ers the operation of which is carried out in eonj unction with an optical arrangement shown in Figs. 15 and 16. On the rail 1 is fixed a telescope 43 and at a distance away a cross hair 4:4. The adjustment of' the rail on the holder is performed as follows. Two pairs of dividers as shown in Fig. 14 fit 'with their wingnut-ends. 39 in the holes 34 of the fixed part of the holder while the ball-ends 40 engage'with the holes 36 in the corresponding -movable parts of thelolder (rail-bracket and side plates). By turning'the screw spindle 42 by means of the hand-wheel 41 the movements of the 'rail-holder 'parts'ean be carried out very lexactly; 'For the. alignment the optical ar- 'rangement is employed until the desired positionis attained. On the dividers may besmounted a scale for reading ofl' the movement given'; When the adjustment of the various parts has been'concluded by means of ,agauge or similar' device, the appropriate looking-plates are selected from the series having bolt-holes, the distance apart of which is appropriate to the particular case. c

These plates 38 will be bolted up with their projections engaging in :the spaces 37. For the easier selection ofthe appropriate plate they will be stamped with indicating narks .u

and so formed that one set of plates can be used' for both adjustment-s. Naturally the two separate adju'stments can be provided for at different positions on the bearer-arms.

For instance the horizontal adjustment can be made by means of the rail-bracket at the end'of the bearer-arms and the vertical adustment provide-d for at the point where the supporting arms join the girderwork. J\ decsve factor n this question is as lxfol'v explamed the distribution ot the spi-unguasscs.

The constructions supporting the mil must be shaped to conform with the circm'- stances ot' any particular case. If an existing railway, canal or road be used in order to save earthwork and transport-costs the Construction for carrying the quick-railwav must have a profile such as to allow the particular traflic to pass freely. They (our-:ist then of girders carried on posts or art-.hes (see sections Figs. 17-23). In the ari-angement of this -girderwork is taken into rousideration that inspection and repair-ork must be carried out on the track and consequently platforms 47 (see 18,' 20, "22, and 23) are provided and in addition a track 46 (see Figs. 17-22) along which re pair-cars 45 can travel. Also the repair-cars shown in Figs. 17 to 19 and 21 and 22 cau springs with one another, and rails Secured to the free ends of the said brackets.
