LINTEL-BAR.

Specification of Letters Patent.

Patented Jan. 28, 1913.

Application filed December 5, 1911. Serial No. 664,108.

To all whom it may concern:

Be it known that I, WALTER M. Evmmo, a citizen of the United States, residing at Duluth, in the county of St. Louis and S ate of Minnesota, have invented certain new and useful Improvements in Lintel- Bars, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in lintel bars. I

The object of my invention is to provide a lintel bar which can be readily applied to the ordinary steel beam used in structural steel work for supporting the brick or other wall over an opening, or which can be used alone as a lintel bar.

Another object of my invention is to provide a bar of this character that will reinforce the beam or wall and provide a nonslipping surface upon which to maintain the masonr or wall.

Anot er object of my invention is to rovide a superimposed foundation upon w iich a wall or structure may be readily and substantially built.

In the accompanying drawings-Figure 1 is a transverse cross-sectional view of a channel beam provided with my improved lintel bar. Fig.2 is a modified form of the lintel bar applied to an I-beairu Fig. 3 is still a further modified form showing dilferent means of securing the lintel bar to the beam. Fig. 4 shows two of my improved lintel bars secured together forming a beam upon which the masonry may be built.

Referring now to the drawing, 1 represents a channel beam to which the preferred form of my beam is applied. In this form the lintel bar 2 is in the form of an angle having a vertical portion 3(resting against the channel beam and bolted thereto by means of bolts 4. The lower face 5 of the horizontal portion 6 of the bar is at right angles to the vertical portion and preferably smooth and formin a continuation of the lower face of the c annel beam,.as will be clearly shown in Fig. 1 of the drawings. The upper face 7 of said horizontal portion of the bar is corrugated longitudinally, the corrugation 8 starting from the inner and gradually increasing in depth and width toward the outer end, in order to properly proportion the strength of the beam relative to the stress thereupon. The corrugations 8,

the upper side of the base of the beam, as

clearly shown in Fig. 2. In'this form the under face of the lintel bar is provided with a recess 9 adapted to fit the base 10 of the I-beam 11. The upper face is provided with a cutaway portion 12 and a longitudinal corrugation 13, to hold the mortar and the like, the same as in the form shown in Fig. l of the drawings. The lower face 14 of the I-beam and the lower face of the lintel bar are flush, the same as in Fig. 1. In this form the vertical portion 15 of the bar is provided with an opening 16, through which passes the bolt 17, which also passes through the web 18 of the beam and by means of which the bar is secured to the beam.

In the form shown in Fig. 3 of the drawings, the bar is made flat and having the cutaway portion 12 and the longitudinal corrugation 13, thesame as in F i 2, but the vertical portion is omitted. he bar is therefore bolted directly to the base 19 by means of bolts 20. v

In the form shown in Fig. 4, I take two lintel bars, such as shown in Fig. 1, and se-' cure them together by bolts 21, which forms a beam of itselfand forms a lintel bar for the reception of bricks and masonry.

Having thus described my invention, what I claim and desire to secure by Letters Patent -is-- 1. lintel bar comprising a body-portion adapted to be secured to a beam, 'a lateral extension carried by' the body-portion and its upper face having longitudinally extending corrugations increasing in width from the inner edge toward 'the outer edge, the upper faces of the pro'ections forming thecorrugations being in t e same plane.

2. A beam comprising a main metal sup-. port, an auxiliary bar riveted to the main support and extending laterally therefrom for supporting a superimposed wall, said lateral extension of the auxiliary bar having longitudinally extending grooves increasing in width from the inner to the outer edge, the outermost faces of the projections forming the grooves being parallel and in the same plane.

3. A lintel bar comprising a body-portion adapted to be bolted to a beam and having its lower face flush with the lower face of the beam and its upper face having longi: tudinally extending corrugations increasing in width and depth from the inner edge toward the upper edge, the upper faces of the projections forming the corrugations being in the same plane.

4. A lintel bar comprising a base, having longitudinally extending corrugations in its upper faces increasing in width and depth from the inner to the outer edge, the lower' face of the base being smooth, the upper face of the projections forming said corrugations being parallel with the smooth surfaces of the lower face, and a wall extending at right angles to the base for securing the lintel bar'to an auxiliary support.

5. A beam comprising a main flanged metal support, an auxiliary bar riveted to the main support and resting upon the upper face of the flange thereof and extending laterally therefrom for supporting a super-imposed wall and having its lower face flush with the beam, a portion of the lower face of the auxiliary bar made to conform to and snugly rest upon the flange of the main support.

6. A beam comprising a main flanged inetal support, an auxiliary bar riveted to the main support and resting upon the upper face of the flange thereof and extending the beam and its upper face having corrugations increasing in size from the inner edge toward the outer edge.

8. A beam comprising a main flanged metal support, an auxihary bar secured. to said support and restingupon the upper face of the flange thereof and extending lat-- erally therefrom, a portion of the lower face of the auxiliary bar made to conform to and snugly rest upon the flange ,of the support and the balance of the lower face thereof bein flat and in a plane with the lower face of the flange, and the upper face of the said extension of the auxiliary bar having longitudinally extending corrugations increasing in width and depth from the inner edge toward the outer edge, the upper faces of the projections forming the corrugations bein in the same plane.

In testimony w ereof I hereunto aflix my signature in the presence of two witnesses.
