REENFORCING MEMBER FOR CONCRETE Filed Au 13, 1930 Patented Apr. 21, 1931 GEORGE H. REED, OF EATONTOWN, N JERSEY REECNFORCING MERIBER FOR CONCRETE Application filed August 13, 1930. Serial No. 475,052.

This invention relates to an improved clip for re-enforcing concrete, especially for columns and beams. The clipis secured to the metal beam or girder and extends therefrom 5 for a suflicient distance to give proper support to the edges and corners of the cement covering.

The object of the invention is to provide a device that can be installed from one place along the beam from one point as they are connected by a longitudinal wire. This avoids the necessity of a workman travelling along a beam to space and affix the clips.

Another object of the invention is to provide clips that are adapted for use on beams of diiferent widths and within certain limitations the same clips can be used on various parts of a building even though the dimensions of the beams vary.

' Another object of the invention is to provide a clip that presents a minimum of obstruction to the free flow and tamping or puddling of concrete. The clip is easily and cheaply manufactured and can be instantly attached to a beam.

The invention is illustrated in the accompanying drawing in which Figure 1 is an end elevation of a beam with my improved clips attached,this view also showing the mold or centering in which the concrete is molded.

Figure 2 is a side view showing my improved clip and a connecting wire. Figure 3 is a side view of the articles shown in Figure 2.

5 In the drawing 10 indicates a beam and 11 is the mold which is temporarily erected to hold thecement until it sets. The molding is erected after the clips are installed and, the cement is deposited and then tamped or puddled by a tool to seat it well under the beam in order to prevent air holes and subsequent weak portions in the cement. Some clips as previously made are provided with so many strands arranged at various angles and with so many joints that the cement can not flow and is difficult to puddle to a point under the center of the beam. The many wires also offer many points where the puddling tool engages the clip and dislodges it and when the cement is finished and set the of supply as a workman can feed the clips of the beam. These clips are notfirmly seated on the beam. This is avoided by'my new means which comprises a clip formed of astrip, usually round wire. The clip has two divergent arms 12 and .13 which form a V-shaped clip. The

ends of the arms are bent at an angle to the plane of the'arms and these form spacing strands 14. The ends of these strands are adapted toengage the edges of the beam. They are made to fo'rmsockets or open loops 15 which can be easily placed over the edges loops are formed by eX-. tending wire inwardly fromythetops of thestrands as at 16 and then into return bends to form the loops 15.

The clip can be made of spring wire and spring over the edges of the beam. The divergent arms 12 and 13 make it possible to fitthe clips. to beams of different widths and without the necessityof bending the ends and in all cases carrying the spacing arms to a point under the edges of the beams to strengthen the corners of the cement.

The clips may be secured at intervals to a feed or support wire 17 either by brazing or otherwise. This wire 17 not only holds the clips spaced but also assists in holding the arms 12 and 13 parallel with the bottom face of the beam 10.

The wire 17 also serves as a feeding means whereby a workman can place these clips successively on a beam at one point and then push them along and in this way avoid losing time and also avoid danger of moving along the beam to place the clipsin position.

Furthermore, it will be noted that the arms 12 on one side of the centre all incline in the same direction and the arms 13 on the other side incline in the opposite direction. The cement, when wet. is poured into the spaces between the beam and the mold and can flow along these arms without obstruction and thus be easily tamped and puddled to form a solid mass of concrete enclosing the wires and filling the space up to the bottom face of the beam 10.

I claim:

1. A re-enforcing' member comprising a longitudinal tie member, and clips rigidly secured to and spaced along opposite sides of said member, said clips comprising divergent spring arms with the ends bent up to form spacing members extending at an angle to the plane of the arms and having ends bent toward each other to form recessed engaging members whereby the device is fastened to a beam.

2. A device of the class described comprising re-enforcing clip members extended to form horizontally disposed divergent spring arms bent upwardly at the ends to form spacing members which terminateinbeamedge engaging portions, and a longitudinal tie member along which said divergent spring arms are inclined in opposite directions.

3. A re-enforcing device comprising a series of clips, each clip formed of wire bent to form divergent arms and then at an angle to the arms with the ends adapted to engage the edges of a beam, and a wire secured to the clips at the juncture of their divergent arms whereby the clips are spaced and by which they can be successively attached and spaced on a beam from one point of supply.

4. A re-enforcing member comprising a series of spring wire clips of a general V shape with ends spaced from the V and formed into open sockets to receive the edges of a beam, and a wire connecting the clips and secured thereto at the angle of the V of each clip.

5. A re-enforcing means for concrete structures and the like, comprising a longitudinal tie member, transversely distortable re-enforcing spring clip members spaced along said member and diverging from opposite sides thereof said clip members having means at their ends for connection with the flanges of a beam.

In testimony whereof he afiixes his signature.
