June 17,1930 G. H. MILLER CURB FORM Filed Sept. 7. 1928 Patented June 17, 1930 UNITED STATES PATENT OFFICE GEORGE E. MILLER, or MILWAUKEE, WISCONSIN, ASSIGNOR '10 METAL FORMS COR- IPORATION, 0F MILWAUKEE, WISCONSIN CURB FORM.

Application filed September 7, 1928. Serial No. 304,420.

In building of present day concrete structures such as roads, there is employed a reinforcing structure such as steel rods which are extended transversely and in some instances longitudinally of the construction and are embedded in the b'uilding'materials, usually concrete. Where it is desirable to have a permanent curb on the side of the road and at an elevation somewhat above the roadway, the reinforcing rods may be allowed to project beyond the roadbed and imbedded in the material forming the curb prior to the paving of the road; the rods reinforcing both the roadway and the pavement and constituting tie members therebetween.

In constructing a road in this manner, the curb may first be laid with the rods in place, the concrete being poured in between the forms embedding the ends of the rods and forming a support therefor when the concrete of the curb has taken its set. The curb constitutes in this manner a support for the rods while the roadway is being laid in the usual manner as by'machines moving along 7 tracks at the side of the roadway.

It is seldom feasible to lay the curb and the roadway simultaneously, consequently, the utilization of tie members between the two constructions is of considerable importance.

This invention proposes an improved form of curb form whereby to facilitate the laying of the reinforcing for combination road and pavement constructions. In the utilization of curb forms of this character, when the curb has been completed and the materials have taken their set, the curb forms are re; moved and may be used elsewhere for a similar purpose. It is desirable therefore that the curb forms should be so constructed that the sections may be readily taken apart and removed from the projecting rods with a minimum manipulation of parts and without any unlatching operations.

A further desirable characteristic is that the rails should be so constructed for the above purposes that the structure thereof will not be weakened and will stand up with sufficient strength and durability for the stress to which they are subjected.

In order to provide a device filling these requirements, I have evolved a curb form made of sections having a slip connection therebetween and formed with notches through which the tie rods may project. The strength and durability of the construction is maintained by surrounding these notches with a marginal reinforce, which may be in the nature of a flange and which may provide further reinforcing of the side rail by having a bracket member formed thereon. In the construction, is also included, means for attaching the side rails to the ground which may be in the nature of boxes or yokes mounted on the base flange of the device, each having an aperture therein in alignment with an aperture in said flange through which aligned apertures suitable stakes may be driven into the ground on which the side rails are placed. 7

Other objects and advantages will appear in connection with the detailed description of the device which follows and will be incorporated in the claims appended thereto.

In the drawings, constituting a part of this specification,

Figure 1 is a perspective view of a curb form made in accordance with the principles of my invention showing the same from the rear aspect. a

Figure 2 1s a perspect ve-mew of the form viewing the same from the side of the working face.

Figure 3is a detail fragmentarily showing a curb form having a notch therein and illustrating the relation of a tie rod to said notch.

Figure 4 is a section on the line 44 of Figure 3.

Referring to the drawings in detail by reference numerals, the same numerals, designating the same parts in all figures of the drawings, 10 designates the curb form of which the present invention constitutes a' part. The form comprises the usual ground or base flange 11 adapted to rest upon the ground, and an upright flange 12 having a working face 12 which in practice defines the side of the road, curb or sidewalk, and is provided at its top edge with a curved head portion 13 from which extends downwardly the depending flange 14.- and which, with the I head 13, overhang the base flange 11 protectively thereto.

the curb form is made in detachable sections which may be readily taken apart and are of such length as not to constitute too great a burden to the workmen in transferring them from one place to another.

In order that the sections may be detached 2 with facility one fromthe other, the sections are each provided at opposite endswith members designed-to interlock one with the other to hold the working faces of the various sections aligned within the same common plane. Any suitable device may be used forthis purpose. In the present embodiment the means is disclosed in the form of a pair offlangesrespectively designated by the numerals 14 and 15 positioned respectively on the adjacent ends of two contacting forms. The flange 14 is preferably in the nature of a flat piece of metal riveted or otherwise secured to the end of the member to which it is attached and lying flat against said member with a portion thereof projecting therefrom. The flange 15is preferably formed of a short length of angleiron with one flange 16 thereof secured in a suitable manner, as by rivets, to the base flange 11' of the other curb form and having a flange 17 extending upwardly therefrom in parallelism with the flange constituting the working face or body of the device and spaced therefrom a distance equal to the thickness of the member 14*.

When the forms are placed together end to end as shown in Figure 1, the member 14;

will be projected between the flange 17 and the member 12 and will be held in place by these members and the rebent portion 14 of the track head 13. The forms are also provided with suitable means whereby they may be anchored to the ground against displacement or disarrangement from their proper alignment along the roadway. For thispurpose I have used a well known construction in the nature of yoke members 18 having parallellegs 19 secured to the ground flange 11, by flanges 20, and to the upright portion of the device by flanges 21. The base flange 11'and the arched connection 22 between the legs 19 are provided with aligned apertures through which suitable stakes 23 may be driven into the ground and held in position relative to the road rails by means of wedges 24 passing through suitable slots in the legs. It will be noted that the yoke members not only constitute means cooperating with the main structure of the curb form for supporting the stakes 23 but also constitute a substantial reinforce to the sheet metal construction of the road rail.

As has been above stated, it is frequently desirable to reinforce the structure of the roadway by means of metallic structure such as tie rods running in various directions within the aggregate of which the roadway is constructed and where a permanent curbing is to be formed on the margins of the road or a sidewalk to be built'adjacent there to out of material similar to those used in building the roadway, it is customary to allow the tie rods to project laterally from the roadbed and in order to permit this, the curb forms are therefore constructed with slots or notches formed at intervals therein corresponding to the position of the rods.

These notches, which are designated by the numejral 25, are preferably extended through the base flange 11 and about half-way up. the working face 12. By this arrangement it is apparent that the sections of the curb form may be lifted from astride the rods which are designated in the figures by the numerals 26 and removed to another location for further use.

The weakening of the structure caused by the formation of these notches is compensated for by the provision of marginal reinforcement in the nature of sheet metal flanges 27 and 28 extending transversely of the members 11 and 12 and marginallyv of the slots or notches 25. The construction of the device is further reinforced by bracket members 29 with which the flanges 27 and 28 are integrally formed and which extend from the base member 11 to a position substantially at the top of the member 12 and into 0011'.

extending through the notchesv 25 andanchored in position by the stakes 23, forms being positioned, of course on both sides of the proposed curb. The aggregate may then be deposited between these forms in the usual manner by machinesrunning on suitable tracks of a well known character and after the finishing thereof may be allowed to set and obtain a predetermined hardness whereupon the stakes 23 may be removed. and the forms lifted section by section from their position. The curbs so formed may now be depended upon as a support for the rods until the paving of the road has been completed.

. The simplicity of construction of this device makes for its facile manipuluation. No bolts or locks are to be released except the wedges 24 prior to the simple lifting of the sections apart and their removal from one location of usefulness to another. No particular skill is necessary in the manipulation of this device and there are few parts connected therewith which can get out of order.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States is:

1. A road rail of the class described, comprising, in combination, a base, an upright body, a head portion, the base having notches therein which extend part way up the upright body, and reinforcing members placed adjacent said notches, secured to the base and engaging the under side of the head portion for reinforcing the road rail.

2. A road rail of the class described, comprislng, 1n combinatlon, a base, an uprlght body, a head portion, the base having notches therein which extend part way up the upright body, and reinforcing members on each side of said notches and engaging the under side of the head portion, the reinforcing members having flanges secured to the base and upright body portion.

In testimony whereof I affix my signature.
