Description

Patented Sept. l, 1931 UNITED STATES WALTER s. EDGE, OF wnscnninnn NEW JERSEY ME'IAL E01) FOR BUILDING CONSTBUCTION, ET.;

Application filed March 6,

My invention relates to metal rods and their use.

The object of my invention is to provide metal rods and especially iron rocls of small and medium diameters at a low cost and with at least one surface extending longitudinally of each 10d or set of rods, that presents the raw metal of the rod er set, when the same are finished while leaving the 1 remaining surfaces coated with the thin seale with whieh they are eovered when they leave the rolls whieh form them.

My invention will be more clearly understoocl by referring to the drawings which form a part of this specifieation in whieh- Figure l is a cross seetional view 0f a sheet of iron embodying a plurality of circular portions, whieh become separate rods when the sheet is divided midway between the said circular portions by a slitter er saw.

Figure 2 is a similar viewto that shown in Figure l, including a gang of slitters f01' separating the rods.

Figure 3 is a cross seetion of a finished rod embodying 1ny inventio1n Figure 4 is a perspective view of a num be1 of rod's, illustrating an arrangement whereby the raw surfaces are brought into contaet for welding them together.

Figure 5 is a view showing one rod welded t0 another, the rode being arranged at a right angle t0 each other.

Figure' 6 is a cross seetional view of a set of hexagonal rods, as formed prior to separating them into single rods.

The rods may be formed with any des'ired eross section, andmade into single, double, er any pred termined number, as desired,

40 by simply cutting through the web 0f the sheet.

In the following des0ription I shall refer to two or more rods joined by a web 0 1 web portions, as a set 0frods.

A, A, etc. indieate the body portions of the rods and B, B, etc, the web portions formed integral with the body portions.

C, C, etc., indicate the raw metal surfaces provided by separating the rods with saws 01' slitting tools t0 proVide a single r0d 1'928. S61ial N0. 259,393.

asillust rateclin Figure 3, having a web on each side thereof, eachef which is' p'rovidetl with-a r'aw su1faceC', which extends the full length of the rod, while leaving the remaining surface in the normal condition in which it leaves the rolle.

D, D, D, ete. inclicate the saws.

It is obvious that a web may be formed on one side 0f the rod only by sawing through the sheet direetly adjacent the body 0f the rod on one side, thus leaving a web on the oppositesicle only. The advantages 0f this construction are; first, the 1OCl is stronger and stiller by reason of the web portions; seeond, the raw surfaces per1nit 01: easy spot welding, and third; they are less costly to make by reason 0f a nun1br being rolled simultaneously.

Where concrete is to be 1e-inforced by rods, as in buildings and clam eonstructions, etc., I may use a set 0f rocls in place of single r0ds in many cases ancl reduce the cross seetions in size in many instances, tlms saving in weight of metal ancl at a lower cost.

I am aware that rocls have been rolled o1 formed by rolling in sheets t0 provicle separate rods at a low eost, but I believe it is new to provide rods with webs as above 4 set forth and with webs having a plane raw surface extending their entire length anal provided by the process of making as above set forth, and therefore believe both Ehe process and produet t0 be new und useful.

Having thus described my invention I elaim as new ancl desire t0 secure by Letters Patent:

l. A metal rocl 0'f the character clescribed having a web fonned integral therewith extending its entire length and having one sicle of said web provicled with a plane surface exposing the raw metal resulting from a sawing 01 shearing operation.

2. A metal r0d of the character deseribed having a web formed integral therewith extending its entire length on opposite sicles thereof, eaeh web having a plane surface exposing the raw metal resulting from a sawing 01 shearing operation.

3. A rolled metal 10d 0f the character sie described having a web formed integral therewith extending longitudinally thereof its entire length, the outer face 0f the web exposing the raw metal resulting from a sawing 01 shearing action and the remaining portion being covered by its outer normal covering as it leaves the rolls which form it.

4. A rolled metal rod of the character described having web portions formed diametrically opposite to each other and extending the entire length thereof and having their outer faces formed with plane surfaces exposing the raw metal resulti1'1g from a sawing 0r shearing action.

In testimony whereof I have affixed my Signature.

WALTER S. EDGE.
