OHIO, A CORPORATION OF OHIO FORM FOR CONCRETE ROAD CURBING Application led November 14, 1927. Serial No. 233,016.l

This invention relates to a form for concrete curbing.

It is often desirable to provide a raised curbingalong one or more edges of a conoreted surface, as, for example, the edge offa concrete roadway. Of course, there are other concreted surfaces where it would be desirable to provide curbing, and it should be understood that concrete roadways are speciically mentioned herein simply as an illustration of a well known concrete surface commonly provided with a curbing.

In covering a surface, suchas a roadway, with concrete, it has been customary to cover a part of such surface and then to build up on the part thus -constructed the required curbing. Difficulty has been experienced in constructing the curbing because of the fact that the form used therefor has had a tendency to shift during the pouring and tamping of the concrete. Of course, after the original concrete surface has fully set and the usual side form therefor removed, it has been possible to Vuse a curbing'form, anedge of which engagesthe ground, which will not shift during the pouring operation. However, this method of constructing the curbing has the disadvantage of eliminating the bonding action between the concrete of the curbing and the concrete of Ythe surface, which occurs when the former is pouredv before the latter has fully set.

The principal'object of the present invention is to provide a form for concrete curbing which will not shift transversely during the pouring and tamping operations, and which,

therefore, permits the curbing to be poured beforel the concrete ofthe surface has fully set;

.f @Other objects and advantages, such as ease ofvapplication and location of the form, cheapness of manufacture,'as well as details of construction, will more fully appear hereinafterfas the description proceeds. 1

In carrying out Ythe invention, itis contemplate'dlto use longitudinally extending memhers'spaced'transversely from each other a widthjequal to 'the curbing width desired. @ne of these ymembers will be provided with meansl for ,maintaining -the form against transverse displacement, while both of the members will be provided with means for supporting the form upon the edge of the concreted surface in the necessary horizontal plane.

An embodiment of the invention is illustrated in the accompanying drawing, wherein F l shows the form in perspective, and Fig. 2 shows the form applied to a concrete surface with the curbing arranged therein, said view being a' vertical section through the form, curbing and concrete surface.

The form comprises longitudinally eX- tending side members l and 2. These members are spaced transversely of each other a distance equal to the desired width of the curbing. The member l is of plane configuration, while the member1 2 is an angle, the foot 3 of which is of less width than the main part. The side member 1 is formed with a vertical width greater than the vertical Width of the main part of the member 2, for a purpose which will later become apparent.

An angle member il, the bottom of which is in the same horizontal plane as the bottom of the foot 3, is secured to the outer side of the member l. This angle member may extend the entire longitudinal length of the member l, or there may be a number of separate angle members of less length secured to the member 1 but longitudinally spaced therealong. In order to maintain the members l and 2 in their proper spaced relationship, cross members 5 spaced longitudinally of the form have their opposite ends secured respectively to the members l and 2. These cross members are in the form of substantially U-shaped angle bars, the legs of the U being the portions that are secured to the longitudinal members.` 'In order to give strength to the form as a whole, the cross members illustrated are in t e form of angle bars, but it should be understood that such members may take other forms. In the present embodiment, the cross members 5 are secured to the membersl and 2 by welding the same thereto, but it should be pointed out that other securing means are within the purview of the invention. l'

Likewise, it would seem opportune at this time to have it clearly understood that ab though the form is shown as made up of sheet .metal it might equally as well be formed Vof wood or other materials.

As heretofore pointed out, it is customary to construct the curbing for a concrete surface after .a portion lo f suchsurface has been poured and surfaced. This method .isfollowed either before the concrete of the surface has fully set `or after it has fully set. The form of the present invention particularly adapted for use in the first method of constructing the curbing although nit ,could be used with the latter. The manner in which the form is arranged upon ,the concrete sur,- face is clearly shown in Fig. 2. It is placed in ,position yalong .the kedge of the surface so that .theangle ..4 rests .upontheupper edge ofv the usual side form imember .6, while lthe foot ,.3 rests upon .the .upper surface .of the concrete. This application of the form .to the concrete should .preferably .take place prior to the .time that the concrete willfhave become permanently and fully set. /Vhile the usual side member 6 may be vprovided with a straight upper edge, it has been found convement, not only in .applying the. .curbing form but also in positioning ,the side member 6, to provide such upper edge with an outwardly and downwardly turned portion 7. When the curbing form has been positioned with the angle 4 upon the upper edge .of the side member 6 and the foot 3 upon the .upper surface of the concrete, the lowermost portion 8 of the member l will extend downwardly behind the side member 6. This lowermost portion, when thus engaged behind the mem? ber 6 together with the angle member 4, will clearly prevent transverse displacement of the curbing form outwardly of the concrete surface or roadway, Therefore, when the concrete is poured for lthe curbing, the form will be held against shifting outwardly and will also be held against shifting inwardly. The last mentioned shifting movement is prevented because of the fact that the curbing form is preferably applied before the concrete has permanently set, whereby theV part 8 will extend downwardly between the member 6 and the main body of the concrete. Hence the portion 8 will be held against trans? verse movement inwardly of the roadway or other surface by the restraining action ofv the concrete. It will thus be possible to quickv ly and accurately arrange the form for re- 1 @giving the Concrete. .curbing in such manner that .the .curbing will .follows .definita meas.

'termined line along .the edge-of the roadway.

After the concrete' ofthe curbing and the Concrete. of the roadway-have become were manentl-y .set Qr have .Set .sufficiently to, allow the removal ef thevform, the .Gross members 5 will prevde a convenient romasaing Suchyremeval- .Freinthe. iferesei ng description; it will be apparent that thefermaeelnprisngthe pres-- ent invention is of such construction that it may be readily positioned and located in its properplace along the edge of the roadway, and will, at the same time, remain definitely in position during the pouring, tamping, and setting of the concrete.. Because of the fact that theform will be held against transverse vdisplacement by the usual side form 6 and the cOnQrete, it .will .be possible to pour .the concrete v.of Ythe curbing before the. concrete of the roadway has becomel fully and perma nent/ly set, thereby procuring aI bonding ac-A tion therebetween so that the roadway and its .curbing wil-l :in .reality be a continuous, unitary, concrete body. l

The invention will be susceptible of .variations, modifications, and adaptationswithin the .scope of .the .appendedclaims- Having .thus described .my invention, il claim: A a 'Awformy for a concrete curbingcomprising :members spaced transversely of each other a .distance equal. to the :curbing width desired, and means on .each of said members to support the form horizontal.ly,.the means on one of said .members .together with the member forming .an angleV .adapted v.to `engage the top and side o'f vthe .usual side form to position the curb' form and .to hold .the same against 4transverse movement.

2. A form fora concrete curbing adapted to :be applied to an edge of a concrete surface before the concrete thereof .has permanently set comprising interconnected spaced longitudinally extending members of unequal vertical width, the member of'greatest vertical width adapted to lie adjacent the edge of the concrete surface and to extend between the same` and the lusual side form therefor a .distance equivalent to its width in excess of that of the other member.

3. yA form for a concrete vcurbing. adapted to be applied to a concrete surface after the main body of the concrete has been poured and before the same has permanently set com'- prising longitudinally extending members spaced'transversely of each other a distance equal to the curbing width desired, horizontally extending means on both of said members for nsupporting the formfupon thev concrete surface, and vertically extending means on one .of said members for' holding the form againstl transverse displacement.

4. A form for a concrete curbing adapted.v

to be applied V:to lan edge`of a concrete surface before the concrete 'thereof' has permaiA nentlyset comprising interconnected longitudinally extending members 'spaced 'translV versely of :each-other a distance equal to Jthe curbing width desired, on'eof. saidmembers having a base portion of 'substantial hori' zontal Awidth andv thefotherv of said members being of grater'vertical widththan therfirstl named member, supporting means .for said' last-.named member egnneetedgthereto sorthat.

the bottom surface of such supporting means lies in the same horizontal plane as the bottom of the base of the first-named member', whereby when said form is applied the base of said first-named member will rest upon the upper face of the concrete inwardly of the edge thereof and the supporting means upon the other of said members will rest upon the upper part of the usual side form for the concrete surface, while the lower portion of the last-named member will extend downwardly between said side form and the concrete so that the curbing form will be held against transverse displacement in either direction.

5. A form forl a concrete curbing comprising a longitudinally extending vertical member, means secured to said member intermediate its upper and lower edges extending horizontally outwardly thereof, a second longitudinally extending vertical member having a horizontally extending portion along its bottom edge lying in the same 'horizontal plane as the means on said first member, and means interconnecting said members to hold the same in parallel relationship, the portion of said first-named member below the horizontal means being adapted to hold the form against transverse displacement.

In testimony whereof7 I hereunto aiiix my signature.
