LINTEL BAR.

Application filed October 24, 1927. Serial No. 228,191.

This invention relates to lintel bars to support masonry over window openings in walls and like structures.

The object of the present invention is to generally improve and simplify the construction and operation of bars of the character described; to provide a lintel bar which can be readily attached to the ordinary steel beams used in structural steel buildings to support the brick or other material employed over a window opening or the like, or which can be used alone as a lintel bar; to provide a built-up structural steel lintel bar which presents a slot for the reception of a steel window sash and which is so positioned that the lintel bar may deflect or settle without imposing any weight or load on the sash; and further, to provide a lintel bar which may be used across spans or openings of practically any dimension without changing the structure thereof.

The lintel bar is shown by way of illustration in the accompanying drawings in which:

Fig. 1 is a perspective view showing a. window opening in a. wall and the type of sash with which the lintel bar is used,

Fig. 2 is an enlarged sectional view on line IIII, Fig. 1, showing a. crosssection of the lintel bar,

Fig. 3 is a. similar section. showing a. modi fled form of a lintel bar.

Referring to the drawings in detail and particularly Figs. 1 and 2, A indicates a brick wall or the like in which is formed a window opening for the reception of a steel sash, such as indicated at B. Extending across the opening for the purpose of supporting the brick work is a lintel bar, generally indicated at C. The bar shown in this instance is a built-up bar as it consists of three sections of angle iron, such as indicated at 3, 4 and 5. These bars are assembled as shown in Fig. 2 and they are secured with relation to each other by a single row of rivets or the like as indicated at 6. The upper bar 3 separates the lower bars 4 and 5 and as such provides a continuous slot 7 across the window opening which is adapted'to receive the upper portion of the steel sash indicated at 8. A bar constructed in this manner has a numbenof advantages, first, it provides a bar which combines great strength with low cost of ma terial and fabrication, secondly, a bar is pro vlded, in the lower face of which is formed a groove to hold the upper portion of the sash in position, third, it produces a bar which may deflect or settle without imposing any load on the sash proper, fourth, a bar is provided which may be readily attached to the steel frame of a structural steel building or which may be used alone as a lintel bar, fifth, a bar is provided which forms an ideal support for the brick work or other material employed, sixth, a bar is provided which is suitable for practically any span which may be encountered, i. e., a number of lintel bars are employed which are suitable for spans of 6 ft. and less, but special bars are usually required where the span is greater. The lintel bar shown in this instance is capable of use in either instance without resorting to any changes except in the size of the angle bars employed, and seventh, a bar is provided with a wide top flange, such as indicated at 9 which provides lateral stiffness and materially increases the load carrying capacity of the bar.

Another form which the lintel bar may assume is shown in Fig. 3. In this instance, two lower angle bars are employed as indicated at 10 and 11. These are separated by alongitudinally extending plate 12 so as to form a slot 13 for the reception of the sash; and where greater strength is required. two upper angle bars may be applied as indicated at 14.

While certain features of the present invention are more or less specifically described, I wish it understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finishes of the several parts employed may be such as the manufacturer may decide or varying conditions or uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent 1. A lintel bar comprising a pair of angle bars adapted to span a. window opening and a third bar disposed between the angle bars and riveted thereto, said third bar forming a spacer between the angle bars and the lower edge of said bar being disposed above the base flanges of the angle bars so that a. 1ong1- tudinally extending slot is formed between flanges of the angle bars so that a longitudithe base flanges of the angle bars. nally extending slot is formed between the 10 2. A- lintel bar comprising a. pairnof angle base flanges of the angle bars, and a flange bars adapted to span a Window opening, a formed on ithe upper edge of the: third bar 5 third bar disposed between the angle bars and and paraliel with the base flanges of the angle riveted thereto, said third bar forming a bars. spacer between the angle bars and the lower edge of said bar being disposed above the. base STEPHEN S.
