CONCRETE-REENFORCING MEMBER.

Application filed July 5,

To all whom it may concern.-

Be it known that 1, JOHN G. Turn, a citizen of the United States, and a resident of Youngstown, county of Mahoning, and

State -of Ohio, have invented a new and use 'ful Improvement in ConcreteReenforcing Members, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention relates to reenforcing elements for concrete construction. More particularly it involves insert members so con- 16 st-ructed as to be securely anchored in the adjacent concrete and having an outer face designed to be seated flush with the surface of the concrete so as to serve as at protecting element therefor and where desired, also afford a point of attachment for shaft hangers, fixtures, etc., in concrete buildings. The object of my invention is to improve metallic inserts of this character and to distribute the metal used in their manufacture in such a manner that the maximum of supporting strength may be obtained from the least amount of structural material. Through the use of an I-beam cross-section, I may produce an insert of great rigidity. Furthermore, instead of punching out sections of metal and anchoring the members by means of auxiliary parts, I form the anchoring members from the punched out portions. Other objects of my invention will appear in the course of the following description.

My invention also includes a simplified method of producing a reenforcing member of this character and in place of a series of machine operations, I employ but two operations, a rolling and a pressing operation. This may be followed by a punching operation to provide the anchoring elements referred to, where it is desired to so imbe-d the reenforcing member as to permit it to withstand severe strain.

To the accomplishment of the foreogoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claim. I

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one 1921. Serial No. 482,301.

of various mechanical 'forms in which the principle of the invention may be used.

In said annexe-d drawing Fig. l isa perspective view of a reenforcing-insert showing a channelway with an anchoring element in place, as well as an auxiliary reenforcing bar;

Fig. 2 is a detail perspective view show ing the end closure of a channelway in position;

Fig. 3 is a fragmentary bottom plan view; Figs. l to 7 are each detail cross-section views showing the channeled insert at various stages of its construction;

Fig. 8 is a perspective view ofthe curbbar type of insert, and

Fig. 9 is a cross-section view "of the bar crete constructions (see Figs. 8, 9) or it I may be an insert bar 3 in which the outer portion 4 is of channel-like form designed to provide an anchorage or point of attachment for shaft hangers and fixtures of various kinds.

In making an insert bar of the type shown in Figs. 1 to 7 inclusive, but two operations are employed to shape the main portion thereof.

First a bar is rolled to the cross-sectional outline shown in Figs. 6 and 7, having a central upstanding web 5 on its upper side and narrow downwardly extending flanges 6 at the margins of its horizontnllv extending portions 7. At intervals regular indentations 8 are formed in the lower edges of the opposite flanges (see Fig. 3). At the top of the web 5 a T-head 11 may be formed giving to the entire insert bar the structural strength of an I-beam.

As the second step in forming the channeled insert, the outer sections of the horizontally extending portions 7 to each side of the position of the web 5, are pressed downwardly to vertical position, as shown in Figs 4 and 5, and the lower portion of the insert bar is then of substantially rectangular cross-section, the narrow flanges 6 forming its base having their adjacent edges 9, which may then be moved in the slot to any position desired.

To prevent plastic concrete entering the channel-way, the open ends thereof, prior to insertion of the bar, into permanent position,v are closed by means of caps 10, preferably formed of light metal and having a notched flange to closely engage the end of the channel portion of the bar.

The web preferably has punched therefrom two holding elements, 14; and 15, bent in opposite directions and preferably attached to the Web atrespectively opposite ends. These punched out elements serve as anchoring members for the insert and are most: effective when bent downwardly as well as outwardly so as to have their lower ends 16 atan angle to their original position in the web. The bending back of the anchoring members also permits a bar 17 to be inserted through the opening 18 so formed at right angles to the insert member where such additional reenforcing seems desirable.

Where the reenforcing bar is designed for use as a curb bar 1, (Figs. 8 and 9) to be set at an angle upon a curb or upon the edge of a column or upon any other edge of'a construction where a corner bead or curb reenforcement is necessary, the anchoring elements, 21 and 22, may be bent in the same manner as that above described or the punched out portions may be formed to one side of the web entirely and be attached to the web at the same ends (see Fig. 8) although where special requirements make it necessary the adjacent elements may be oppositely directed.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed,.providedthe means stated by the following claim or the equivalent of such stated means be employed. I 1

I therefore particularly point out and distinctly claim as my invention A combined reenforcing and protecting metallic insert for concrete structures comprising a face portion adapted to be exposed as a part of theouter surface of such structure, a web member with a T-shaped head adapted to be imbedded in said concrete 60 forming substantially an I-beam with said* face portion and elongated integral anchoring members inclined downwardly and outwardly from said web member to maintain said reenforcing member in immovable relation to the adjacent concrete, said anchoring members leaving elongated openings in said web members.

Signed by me, this 29 day of June, 1921.

JOHN C. TIMM.
