Fig. 4 is a section showing a slightly modified form of wird suitable for use when bricks or bloc s are used.

lJig. 5 is a detail perspective view of a B modification showing a different manner designates a cross tie which may be of any usual or approved construction, and for the tie shown, it will be understood that the ordinary metallic yokes commonly used in the construction of underground street railways may be substituted.

The tie may rest upon any suitable foundation, such as soil, ballast, concrete, etc., and in the present monolithic system of pav ing illustrated, thc tie is superimposed upon a concrete base 3 which supports the binder 4, and wearing surface 5 of asphalt, but it should be understood that my invention is equally appropriate to pavements wherein the wearing surface is of concrete, bricks, blocks, etc.

The numeral 6 designates the rail of ordinary construction havingfillers 7, of concrete or any suitable "material, and'in the present instance, the outer faces of the filler are straight, as indicated at 8,'so as under no circumstances to 'form a lock between the rail. and filler, and the adjacent portions of vthe pavement. Vhere the top portion. of the rail, above the-Web -is narrower 40l than the base, the upper portion of the v,filler is extended so as to be in direct vertical line with-thebase, and where the base of the rail. ,i snarrower than the top portion, ythe filler is extended at the bottom, so that 45, in all cases, -the'side surface of the fillers will be straight.

The numeral '8' designates a Ymetallic guard,.two of which. are preferably einplyed, one on,v cachgsidc otthefraih adja- "S'Ocent to the'. track. `They are ident-ical in form, and one of the. gi'iards on'- which lever side of the .raildesireth may be omitted,

but as before slated, it. is preferable to employ two guards as iii such a case` obviously, 'the paven'iei'itioii bothsides'of the Jin the i'iia'in-., vertical, Ii-Qifi'oii'sf and tegral horizontal l-ior'tions' 10,. and vare of considerable length, in practice being te-ii or more feet long. for a purpose which.v

will presently become apparent.

horizontal portions 10 of the guard at siii able intervals are anchor imembers 11 proieefoo'r vided with eyes 12 which embrace reinforcing rods 13 which are embedded in the concrete base 3, uiid'serve the double func tion of anchoring the guards and reinforcing the concrete und' consequently the paving, adjacent to the rails, and Ato'further 70 reinforce the base, I preferably provide additional reinforcingrods 14 which run. longitudinally of the rails, and are in sections sutliciently long to reinforce the con'- crete above the tie, or they may be continuous, that is to say, only limited in length by the necessities which characterize the easy or practical handlin of the rods. In the form shown' in igs. l and'-2, the guards serve as a boundary for the pavement, wherein the wearing surfacel and binder are brought entirely up tothe rails, which is rendered entirely practical by. the position 'of the parts shown, in that the viration of the rail is not in any Way iinparted to the upper portion of the roadbed, the same' being entirely independent of the vertical movements of the rails, which is one of the most important features of the present invention. Where the pavement is of aI type other than monolithic these guards form a boundary for the bricks ad'acent to the rails.- v

eferringA back ,to the Figs. 1 ,and 4v, the numerals 26 `and '2'7 designate filler-'backersarranged on opposite sides of the web ofthe raili These are preferably slightly seated in the concrete filler'7, and -a-re"preferably formed of asphalt, or a material having yielding or owin'g characteristics. :Spaces or voids as indicated by 28, areleft between base and ball of the rail, at the top andbottom of these members, so as to provide space into'which the material of said members may flow or expand, to correspondto any inward and outward movement jt'he rail fillers' may have. vThese membersfare subor blocksv stantially continuous and extend'iioi'l'thieeni tire length'of the rails, and ofcourse correspond in length to" the filler. This arrange` mentA provides for' the contractionundfexpansion of` the rail fillers and the payel .f

ment adjacent thereto, so vas to maintain' a comparatively tight joint betweenfthe-palr'ts at all times, but not sufficiently tight to prevent the independentvertical movement of the rail and parts carried thereby', whichas has been stated.l is one of the" objects of. the present invention.'

ln Fig; 4 a modification' is shown wherein' the guards are so shaped as to adaptthem 'to receive thebricks or blocks commonly used. instreet railway construction."`-In this instance, vertical portions 15 ofthe guards"- arecorisiderubly longer than' that shown in Depending from the outer edges ofit'lgf principal 'I `zontal portions o f the g'uard'ahown in Figs.

rods 13, as in the main figures.

Fig. 5 shows a modified form of guard,

which comprises a'plate 18, which extends l to the surface of the roadway, and downwardly toa point some distance above the cross tie 1,"` it being important that this plate sto Short of the tie, so as notte have any of te vibrations f the tie incident to travel tobe communicated to the plate, and `through it to the pavement. In thisform, l. provide Ilaterally extending lugs 19 at intervals, having apertures 20 therethrough to 4embrace the` rods 13, to keep the plate firmly tied` to the paving base, and to insure its true vertical position relative to the rail and filler. i

VIn Fi 6, is illustrated another form of anchor'or the guard plate 18. This' contemplates puiichinv or separating ii. lon tudinal section 21 roui the plate and splitting it, as indicated at 22, which section is bent at theA point b at right angles to the plate, und then the split ends ofthe portion 2l are .bent in opposite directions to forni oppositeiy extending anchor arms 23 parvallel Vwith-the mainbody of the plate.

- 13 and 14 and by tyingthe guards to the In the construction shown, .it will'be readily seen that by the provision of l'long guard plates firmlyftied in the base, `a long 'durable wearing surface is formed adjacent to the rails and that the vconstruction is such that I can 'provide a much heavier concrete base than is possible in' ordinary construction, strengthening thev Wearing surface adjacent to the tracks, and .thus giving Vit structural strength at the points where needed, itbe-v ing well knownl that the usual lWearing surface has little or no structural strength. A

`The strength of the concrete 3 is further greatly increased by the presence of the rods rods 13, the ipards are prevented from having any roc 'ng or lateral movement and their inner'faces, adjacent to the railand rail filler, arekept alwaysin true'vertical position.` y The concretebase is stopped in true vertical line with .the inner face of the vertical portions 9 ofthe guards', as indicate-,dat so thiitfrom the top edge-'of the guard to the tie or support for the rail, there is a true `vertical surface and the -rail filler and rail,

are entirelyiindependent of allfportions `of i the roadway abovethe tie, 'so that the `vibrations of the rail, which 'are invariiii ble, u

and `cannot be' obviated are not transmitted,

in any` degree to the `street str iictureadja cent" tothe rai1s,lthus completely protecting the street and adding to. itsrdurability; It Willbe further noted that in fthe con-v struction sho-wn in Figs. 1 and 2, and in the construction shown in Fig'. 3,'the wearing the saine before suggested, teen feet Vin length, or really limited in. length only by the condition incident to cona anchoring rods lis the and 2` In the kind of pavement illustrate d'in' r Fig.V 4, or one in which blocks or-bricks aref` surface and binder 4l adjacent to the rails, 65

'I ain aware that it is not broadly new to provide a rail with guards having for their purpose the prevention ot vibrations oi the rail being imparted to the pavement adj.ficcnl'- the rails, butjso far as l ain aware., these have never `been of' practical c onstifiiction` or operation, either because their'lorni `was"` such that in their use' they were `soinewh atl tied to the rail. and naturallyl partake cfits` short as to virtually become 'the equivalent vmovement, or that they have been inadelso",

and subject to f., condition' of strain and vibra tion length as to cover or span two or more cross ties, and as a matter of fact in will ,be from ten. to .six-i` veniently handling and laying the guards'.

Referring to Figr'?y Which is a detail lonyw ,gitudinal view1 o f so much of a section ofpavement as is necessary to illustrate-tliez.,V

idea, the numeral 25 designates a"seiiesof;

Thisis on account*of-'fiv the fact thatthe-pavement adjacen'ttof the y track is suiiciently reinforced forthis j' sort of pavement by the guard plates.
