ROAD FORM.

Application filed May 20,

The present invention relates to an improved form for use in shaping or moulding concrete roads, pavements, curbing or the like, and has for its object to provide a form of this character which embodies novel features of construction whereby it can be readily set up in operative position or removed therefrom and will result in a great saving of time and money on either large or small jobs of the character mentioned.

Further objects of the invention are to provide a form of this character which is comparatively simple and inexpensive in its construction, which will withstand rough handling without danger of getting out of repair, and which can be used repeatedly with out any appreciable deterioration.

lVith these and other objects in view the invention consists in certain combinations, arrangements and associations of the parts, as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following descript-ion and accompanying drawings, in which I Figure l is a transverse sectional view through a metal road form constructed in accordance with the invention, one of the stakes and hangers being shown.

Figure 2'is a rear elevation of a fragmentary portion of the road form, showing one of the stakes and supporting brackets or hangers.

Figure 6 is a rear elevation of portions of two rail sections, showing the coupling, tongues which, are. utilized to connect the abutting ends of two rail sections when they are assembled in operative relation.

Figure 7 is an end view of one of the rail sections.

Corresponding and like parts are referred to in the following description and indicated in all of the views of the drawing by like reference characters.

For the purpose of illustrating and making clear the fundamental ideas constituting and embodied in they invention, one specific 1920. Serial No. 382,808.

construction has been illustrated by the drawings and will be described in the specification.

- The numeral 1 designates a stake which is preferably formed of angle iron and which has the lower end thereof pointed so that it can be readily driven into the ground. The two flanges of the angle iron stake are each provided at the upper ends thereof with the;

transversely disposed serrations 2, and one of the flanges is provided at an intermediate point in the length thereof with a series of triangular notches 3, said notches being arranged with upper horizontal portions and downwardly inclined inner sides. These stakes serve to support the rail or concrete moulding element, a series of the stakes being driven inthe ground at proper intervals along the line of the form.

The rail is formed of a plurality of similar and interchangeable rail sections 4, said f sections being conveniently formed of sheet metal, and having what may be termed a channel a shaped formation. The working faces a with which the concrete or other plastic material is brought into intimate contact when the form is in use are fiat and smooth, and the longitudinal edges of the rail sections are provided with the rearwardly projecting returned fiangeso. The coupling means which is utilized for connecting the abutting ends of the rail sections is illustrated by Figures 6 and 7 Coupling tongues 6 project from opposite ends of each rail section at opposite sides thereof, the arrangement being such that each rail section is reversible and interchangeable. There are no rights and left's, and it is impossible to make any mistake in assembling the railsections. The coupling tongues 6 are shown as formed of sheet metal pieces: which are seflanges of adjacent sections when a number of the sections are assembled in end to end relatlon. I

The hangers or supports 8 are carried by the rail sections l. Each rail section is provided with one or more-of the hangers 8 and said hangers are shaped to fit accurately against the rear face of the section and en- ,t ust formed with a laterally extending arm 8 which is adapted to litagainst either flange of the angle iron stake, being provided with serrations corresponding to the serrations 2 of the stake and arranged to interlock therewith. Suitable fastening means such as ti e U shaped clamp 9 is provided for securing the arm 8 to the stake. Said clamp is pivoted at 10 to the hanger arm 8 and pro vided with a handle 11 for convenience whe manipulating the same. The U shaped clamp 9 is adapted to straddle the flange or the stake and the hanger arm 8 and bring the two said members into a tight and forcible engagement with each other 1 when the handle is swung outwardly into a position at right angles to the stake. The two arms of the clamp 9 have such a rela- 'tion, however, that when the handle 11 is swung upwardly or downwardly, as the case may be, depending upon the manner in which the elements are assembled, into a position substantially parallel with the stake the clamp will be disengaged from the stake and the hanger arm 8 can be separated therefrom. It will be obvious that, with this construction, the hanger or support can be quickly mounted upon the stake or detached therefrom, and that the hanger verticallyadjustable upon the stake, since the hanger arm 8 can be raised or lowered upon the stake within the limits oi the serrated portion 2 thereof. It will also be obvious that the hanger can be clamped upon either flange of the angle iron stake, this being due to the interchangeability of the moulds or rails.

A pedestal or bearing plate 12 is adjustably mounted upon the intermediate portion of the stake, said plate being adapted to enthe surface 01" the ground and to prevent the stake from sinking after it has been initially driven into proper position. This bearing plate, which is illustrated in detail by Figure 4, is provided with a triangular opening 14 which. is adapted to slidably receive the angle iron stake. The plate is thus susceptible 01: being moved up and down upon the stake, and after being positioned at the proper elevation thereon it is shifted laterally to bring one of the corners of the triangular opening 14 thereof into an inter locking engagement with one of the triangular notches 3 of the stake, as indicated by Figure 3. then in this position the plate is locked against upward movement on the stake, and the stake is prevented from sinking into the ground in such a manner as to destroy the alinement ot' the rail sections.

in setting up the road form a series ot the stakes 1 are driven in the ground at suitable intervals andin proper alinement. The rail sections at may then be assembed to produce a continuous rail which is supported at the proper elevation and held in accurate alinement by locking the hangers or supports 8 upon the stakes 1. Tie smooth working faces l oI the rail sections provide an effective moulding surface for the concrete or plastic material of which the road,

pavement or curbing is formed. The channel rails are so shaped that when using a tam-ping machine or any other device which rides upon the rails, any stone, concrete or the like resting upon the flanges will be dislodged and removed by the wheels 01" the f' .llltlOlllllQ, the flanges being comparatively narrow. It will also be noticed that the top and bottom flanges are similarly shaped" so that the rails are reversible and either flange can beused as the riding edge. This results in convenience in erection, as well as saving, should one edge of a rail be damaged or rendered inoperative for any reason. While one possible embodiment of the inventionhas been illustrated in detail it will be understood that many changes and modifica tions can be made without departing in any manner from the spirit of the invention.
