This invention relates to a combined road form and rail, useful in the-construction of roads, concrete paving, and the like.

It is usual in the paving of roads and streets with concrete or similar material, to employ a metallic form in the nature of a channeled or equivalent shaped beam to serve as a confining wall for the wet concrete and atthe same time be used as a tracir or rail for the concrete mixing or other apparatus supported upon a vehicle. Such metallic forms or rails have been secured and aligned in place by means of various devices comprising straps, stakes, and wedges for the stake to fix and support the rail form in predetermined positions. It is an object of this invention to provide a new type of means for locking a rail form to a stake for supporting the same thereby in predetermined position.

It is a further object of the invention to provide a novel stake binding means which also serves as an anti-buckling support for the web of a channeled road form, and a support for the top flange thereof.

The invention comprises in combination with a channeled rail form, buttress means for directly securing and supporting the web of the railto its base, said means serving as a stake holder for wedging said form in pre determined position to a stake.

Otherfeatures of the invention will be ap parent from the following description and explanation. The preferred form of the invention is herein explained in accordance with the requirements of the patent statutes, but it will be understood that changes may be made without departing from the spirit and scope of the invention. It is intendot therefore, to limit the invention only in accordance with the appended claims.

In the accompanying drawing,

v Figure l is a view in elevation of a rail form fixed in position and strengthened by a plurality of my novel stake buttresses.

Figure 2 is a section along the line 2-2 of Figure 1.

Figure 3 is a section along the line 33 of Figure 1. K t

Figure 4 is a perspective of my novel stake buttress in blank form before it is bent and assembled.

In the prior art, it has been proposed to insert stiffening members between the top and bottom flanges of a rail form, and it has also I6 been proposed to provide such stifl'ening mem bers with straps and stake boxes to secure the form in position. In all of such prior pro posals, one of the objects has been to adequately support the top flange of the form. 00 These prior proposals, however, have not been entirely satisfactory, either because they require a number of complex manufacturing operations in the fabrication of numerous parts, or else they did not provide means to Ciprevent buckling of the web of the rail, and therefore, the web had to be made of great thickness to eliminate this disadvantage. I have obviated the above disadvantages by providing a buttress member which not only 10 prevents buckling of the web portion of the rail form, thus permitting a web of thin section to be used, but also serves as a support for the top rail flange, without being secured or attached thereto, thus avoidingexpense in assembling. The buttress member further serves as a stake fixing member.

Referring to the drawing, a road rail of channeled form having a body or web 1, base flange 2, top flange 3, and depending flange i is provided with apertures 5 in the base flange thereof. Secured to the web 1 by welding, brazing, or the like, is the buttress member 6. This buttress member is preferably of channel configuration and consists of a leg portion '2 and a stake holding portion 8 forming an obtuse angle K therewith. The stake holding portion 8 is provided with an aperture 9 for receiving a stake 10 and is also provided with slots 11 for receiving a wedge 12. The buttress 6 has its leg portion welded, or otherwise secured to the base flange 2 at its lower end 22, defining an acute angle R with the base flange 2. It should be noted that the buttress leg 7 is not bent around the stake 10, contacting therewith only at the aperture 9 and indirectly thru the wedge 12. The wedge 12 is provided with a bolt 13 and nut 14 to serve as a stop to prevent disengagement and loss of the wedge. The buttress Serial No. 542,607.

member 6 is fabricated by notching a suitable channel iron at 15, and shown in Figure 4,

forming bevels 16 and then bending the portion 8 toward the portion 7 to bring the notched or cutout edges 15 together. The slots 11 and the aperture 9 may be placed in the buttress before or after fabrication. If desired, the meeting edges of the notched portionmay be welded, brazed, or the like, but ordinarily this is not necessary.

In placing the rail form in position, the wedge 12 is loosened and the stake is driven into the side of the road bed 26, passing thru the aperture 9 of the buttress 6, and the aperture 5 of the base flange 2. The wedge is tightened when the rail form is adjusted to any suitable position. It will be clear, however, that the form may be positioned first and the stake driven later, or any other arrangement for placing the device in use can be made without departing from the invention.

- The buttress type stake holder and strengthening member may be applied, if desired, to 25 other rail forms. It is preferable to use the same with the channel form as shown, but the invention is not limited thereto. It will also be observed that while I have shown the buttress member provided with a certain angular arrangement in respect to the rail form with which it is used, these angles may be varied together with other details of the invention. The wedge member is placed in slots disposed between the stake 10'and the web 1, to provide a position where said wedge is out of the way with less danger of workmen tripping thereover, and by being placed in the portion 8, providing a good height from the ground with consequent better leverage. However, the'wedge can be disposed on the other side of the stake 10 in the leg 7, if de-- sired.

The angular buttress-type stake holder I have shown, by reason of its special shape and its position when assembled, not only permits easy removal of any undesirable concrete or earth ac'cumulation'around the stake, but also prevents such formation by providing a shelter about the stake.
