"The present invention relates to road form railssuch as are employed in the building of? such articles are shed oflthe rail tread.
Another object of the, invention is the pro vision of novel bracingand stake receiving means on the rail. I Affu'rther object is the provlsion of novel meansfor binfiingthe rail and st aketogether,
andastillfurtheri object is to provide means whichsimultaneousl 1 with the binding of the rail and stake toge her will also create an expansive action'between the tread andbase flangesof the'rail. v r e The inventionhas for another object the provision of novel means for simultaneously clampingorbin ing adjoining rails and corresponding stakestogether. and also obtaining anexpansive action within the rails to secure them together in" alinem nt. p
A stillifurther object is the provision of rail bracing, staking and binding means of siniple, practical and eflicient construction, which maybe readilyformed'from sheet metal ex cepting. the stakes.
With the foregoing and other objects in view, which will be apparent as the descrip tion proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made-within the scope ofwhat is claimed, without departing from the spiritiofthe invention.
The invention is illustrated in the accompanying drawings, wherein Figure 1 is an elevation of the improved form. r A 1 Fig. 21isa cross section of one ofthe rails showingthelbracing and binding means in end view.

6is perspective view of another modi- Fig'sf7, 8 and 9 are views corresponding with F ig. 2'd'ep icting other modifications.
Fig. 10 is a section on the line 10'10 of Fig. '9.
The form rails are bent from "sheet metalo suitable gage, and each rail has the vertical web 14,'base' or base'fla'nge with an upa standing flange orlip 16, and tread or tread flange 17 with a depending secondary flange or lip 18. The bevelled tread issu-bstantially the same asdisclosed in my Patent No.
I 1,637,998, granted August 2, 1927, and provides a single line-of contact immediately above the web 14. Y
" The base15 is wider than the tread 17, and they are connected by a brace 19 of suit-able sheet metal-which has its upper and lower ends overlapping and riveted, welded or otherwise secured-to the lips or secondary flanges 1'6 and'18, preferably at theinner side" thereof. One of the braces19 may be located adjacent to each end of the rail and one or more braces may be provided at points between theendsofthe rail. Said braces connecting the trea'd'and" base of the rail will strengthen same opposite to the web 14.
Each brace '19 has an 'outstruck or outwardly pressed portion 20 with an upper aper-' ture 21 to receive a stake 22 driven downwar'clly through the brace into the ground or sub-base, the rail base 15 having an aperture 23 below "the aperture 21 for the passage of the stake. The portion 21'is semi-circular in horizontal section so'a-s to'fit snugly against the stake 22, and the aperture 21' is ofja siz to'snugly receive the stake, so thatmaterial falling overthe tread of the rail will not drop down around the stake-within the stake opening or socket. The portion 20 also'provides a concaved seat forthe stake.
A'binding member 24. composed of alplate of suitable sheet metal, is slidable in the rail,
7 and as shown isslidable init-he adjacentend portions of adjoining alined rails to maintain said i-a-ilsin a'linement end to end. The menr bei- 24'hasthe upper edge portion 25 inclined to bear upwardly against the tread 17 of each rail, with the upper edgeofjthe member 24 seating in thebendbetween the web'l and tread 17, and the lower edge portion 26 of said member-is inclined re'vei'sely and-seats in the bendibetween the web 14 andbaselfio f each rail. The member 24 has the outstandin portion 27 of-V-shaped erosseeefiien provitl is l'QrilllQllt in vertical and horizontal direciug a ridge extending lions t ransversely ot' the rail. edges 28 are pr ed outwardly from the ridge of the portion 2? to contact with the stakes l2 behind the braces 1!). so that when the member Q-l is driven behind the braces and stakes (toward the left in 4;). the members Q-Lt tend to separate the rail webs ll and stakes thereby clamping the stakes against the portions 20 and bases 15. This will bind the rails and hitllfl together to prevent relative vertical nmvement thereot. At the same time, when the member 2% is driven between the webs 14 and stakes 22, said member is brougl'itunder compression, tending to flatten said member, and as a result the upper and lower edges of the member are moved or forced apart against the tread and base of each rail. The member Q-t is thus given a vertical expansive action so as to bring the upper and lower portions thereof tightly against the treads and bases oi the rails. therebv creating a binding action between said member 2a and rails simultaneously with the binding of the rails and staliestogether. This will securely bind the rails, stakes and member it together, to hold the rails together in atinemcnt and in proper position on the stakes.
The member '24 has a. striking lug 29 thereon near one end to receive the blows of a hammer or other implement for driving the member it in either direction, and it will be apparent that the member 52% may be retracted into one rail (the right hand rail as seen in Figs. 1 and i) when the rails are separated and assembled, and said member may then be driven into the other rail when they are positioned end to end and the stakes 22 driven through the apertures 21 and 23. As the wedges 28 are. driven into engagement with the stakes as seen in Fig. 4-. thereby clamping or binding the stakes and braces together; the pressure everted on the intermediate po1= tion of the member ll will be transmitted upwardtv and downwardly to the upper and lower edges ot said member so as to t'orce them tightly against the treada and bases of the rails. thereb binding the member 24 and rails together also. l driving the member 2iin the opposite direction this will relieve the pressure between said member and rails. as well as releasing the stakes 22. \Vith this arrangement it is possible to simultaneously bind the rails and stakes together as well as binding the rails together through the joint member ll. The member Q-l may be positioned to hold the rails in alinemeut with the stakes 2' loose so that the stakes may be driven or withdrawn while maintaining the rails in alinement endto end. When the member llis retracted the rails may be assembled or separated, and the stakes 92 may also be driven into pla e or withdrawn. and by a single op eration. that ol driving the member 'i-l into place. the rails stakes and member :L'l ar bound togethcrczu-h to the others. The membcr 2i may also be moved to releasim position iron: the stakes while maintaining the rails in alinem tband it is unncr'e -sanv to remove the stakes. and the stakes may alro be renlovcd without releas-;ing the member '2 l thus providing advantages in building up and launching down the form. When the mcu'ibcr 24 is drivon out of wedging contact. with the stakes it is capable ol' sliding 'i'reelv in the raile, but when it. is driven into wedging contact with the stake. said member expands or spreads vertically so ttf-t to become tightly (lfx'litllltltll between the treads and bases of the raila. The lug E29 striking the brace 19 will prevent. the member 2 -itrom being driven too tar so as to pass completely from the corresminding rail. and will prevent the wedges 28 from pass-i 9' beyond the i-ttll((f-l.
Fig. 5 shows a horizontal rail tread 17 on which is bolted or otherwise secured an angle iron 30 having an upstanding flange above the rail web to support the wheels of bridges, finishing machines, etc.. as well as strihcotl's and other inmlements on the rail with a single line of contact. The rail tread 17" as well as the rail tread 17 above described may thus be made of considerable width, whereas is would be impractical to make the ordinary rail tread of unusual width because the surface would be too wide for the contact of: the wheels of finishing and other machines, owing to the fact that sand, pebbles, stones and other particles would accumulate on such rail treads. whereas with the present invention a wide tread may be used with only a single line o't contact between the tread and the wheel or implement n'ioving thereon.
Fig. 6 illustrates an auxiliary tread 31 mounted on a horizontal rail tread 17*, said aimiliarv tread 3-31 being of triangular section, and may be formed of sheet metal or tubular stock, to provide a single line oi contact and a beveled or inclined surface sloping outwardly from said line of contact. As shown. the inclined or bevelled portions are pressed downwardly. as at 32. for receiving clamping bolts or elements which tasten the auxiliarvtrcads down on the. rail treads.
Fig. 7 showsa portion 17" bent back outwardly from the upper edge of the rail web it", and having an outstanding flange 19" to which the upper end oi the brace 19 is secured. The binding member 24 has its up per end 25 extending verticall into the pocket or groove between the web ll"- and portion 17 The doubled portion or bend between the web It and portion 17" provides a single line of contact for the wheel or device which moves on the rail.
Fig. 8 illustrates a rail the tread 17 of lit) which is bevelled outwardly and inwardly so as to slope insopposite directions, {whereby sand, pebbles, stones and other particles will be shed inwardly and oi twardly. The tread has aridge formed by a rather sharpangle so as to provide a single line. of "contact for wheels and other devices movable on the rail.
The binding member 24 bears upwardly underthe ridge of the treadand has a downturned fian e 25' hearing against the inner portion. of ihe tread 17% I Figs. 9 and 10 illustrate the use of oblique slots 28 in the portion 27 of the member 24 through which the stakes 22 pass when in (toward the leftin Fig. 10) with the stakes 22 driven downthrongli the braces 19, slots 28.and rail bases 15". The inner edges of the slots 28 as well as the wedges 28 provide oblique cam surfaces to contact with the stakes for binding the parts together.
-may also be used in connect-ion with braces and stakes between the ends of the rails, and
said members when used with individual stakes may be of shorter length and need have only a single wedge 28 or slot 28", the
double wedges or slots being used at the rail joints.
