FRANCIS LEE CASTLEMAN, OF PEN COYD, PENNSYLVANIA.

COLUMN CONSTRUCTION.

Application led January 19, 1923. Serial No. 613,655.

To all whom t may concern:

Be it known that I, FRANCIS LEE CASTLE- MAN, a citizen of the United States, and resident of Pencoyd, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Column Constructions, of whlch the following is aspecification.

My invention relates to buildin columns and particularly to compound co umns for use in constructing the frameworkof high buildings and similar structures, and has for its object the provision of a compound column, H-shaped in cross section, wherein the outer faces of the column in a direction parallel to its web are equidistant from each other throughout the length of the compound column, or throughout a portion of the length of the compound column through a number of successive stories. It also has for its object the provision of a compound H-sha ed column wherein the overall dimension ace to face of the column sections is made constant in adjacent, similar columns of varying cross sectional areas.

In high buildings employing compound columns the cross sectional area decreases from the bottom section upward, because the load on the column also 'decreases from the bottom towards the top thereof. Heretofore, it has been the practice to vary the overall dimension, face to face ofthe cover plates of the columns with variations in the cross sectional area, so that, in a direction parallel to its web, the distance between the outer faces of the cover platesof each successive column section upward is less than that of the preceding section. It also has been the practice with different loads due to different paneling or concentrations on upper floors and requiring different areas, to increase or decrease the dimensions .over the outer faces of the column cover plates in accordance with the sectional area of the column. This practice hasbeen due to the fact that in H-shaped columns as heretofore built, the web plates have been of uniform width and the distance back to back of the angles on the edges of the web plates a constant dimension, while the cross sectional areas of the columns differed and the distance between the outer faces of the cover plates of the columns varied in adjacent columns or in adjoining sections of a column or both.

from face of walls and center of column.

If the outer faces of columns for successive floors and adjacentcolumns are placed in a vertical plane to make the connections of the lwall beams alike-for adjacent columns and for successive floors, then the center of the columnsbecome out of line for adjacent columns and for columns at successive floors, land this makes the interior framing to the columns different for each column, having a different area and different for each successive floor. Such arrangement also leads to complication in the location and settin of the columns due to the variations in co umn centers.

According to my invention a compound column is provided which has a uniform dimension over its flanges with varying cross sectional areas in different sections of the column. This construction also permits a column adjacent to the one shown but having a different area at each floor to be constructed with the same distance over the flanges. Thus the adjacent column may start with the section designated generally by the numeral 3 on same floor where column ,shown has section 2 and have section 4 on next iioor, or same floor that column shown has section 3, and so on upfward, both columns having the same distance over the outer faces ofl the flange angles.

In the accompanying drawings, forming part of this specification, Figure l is a side elevation showing the lengths or column sections of the upper portion of a compound.- column embodylng my invention.

Figure 2 is a similar view showing the lengths or column sections of the lower p01'- tion of such column, being a continuatimi` from the line X-X of Figure 1.

Figure 3 is a transverse section of the column on the line III-'III of Figure 2.

Fi re 4 is a transverse section on the line V-IV of Figure 2.

Figure 5 is a 4transverse section of the column on the line V-V of Figure 1.

F' re 6 is a transverse section on the line- I-VI of'Figure 1. l

Figure 7 is a plan showing a typical building floor construction using compound columns made in accordance with my -invention.

Figure 8 is a similar plan of a building 4floor at a higher elevation in the height of the building of Figure 7.

Referring nowl to Figures 1 and 2 of the drawings, the numeral 2 in a general way designates the lowermost length or section and 3 its lengthwise adjacent section, in a .compound column made in accordance with my invention. The lower end of the next section 4 rests on the upper end of the section 3 and the lower end of the upper section 5rests on and is supported by the upper end of the adjoining section 4. The joints at the abutting ends of the transversely divided column sections 2, 3, 4 and 5 are joined by means of splice plates 6 in assembling the compound column.

By reference to Figures 3, 4, 5 and 6 ot t e drawings, it willl be seen that each length or transversely divided section of vthe compound column is formed of a web plate 7 having pairs of angles which are riveted to the sides of the web plates at the longitudinal edgesthereof with the op-A positely extending legs of the angles 8 forming anges, to which, in the sections shown by Figures 3, 4, and 5, cover plates 10 lare riveted.

The web plates 7 of the various sections of the compound column generally are of the same thickness and likewise the angles 8 generally will be of the same size and cross sectional area, in each of the several lengths or sections making up the assembled compound column. However, when `found necessary or desirable the thickness of the web plates 7 and the size or thickness of the angles 8, or both size and thickness, may vary, in making the cross sectional area of each column section less than that ot' the colunm section immediately below, it.

Each of the column sections 2 3 and 4 is provided with cover plates 10, these lcover lplates as shown extendmg lengthwise from end to end of the section of which they form part. The cover plates are riveted to the angle members 8 of the column in the old and well understood manner. The cover'plates 10 are made of varyin thick.- nesses, each section or length of t e compound column generally having cover plates of less thickness than that of its lower, abutting section, butin columns embodying my invention the outer faces of the cover plates on any one column section are in alinement with the outer faces of the cover plates of its abutting column section or sections.

The'uppermost section 5 of the column illustrated .in the drawings is shown 'formed volf a web plate 7 and angles 8, the cover the angles 8 in the same manner as in the lower sections of the column.

By reference to Figures 1 to 5 it will be seen that the cover plates 10 on the section 2 of the columns are generally ot' greater thickness and of greater cross sectional area that those on the column section 3 supported by the section 2, shown in Figure 3, andthat the cover plates ot' the section 3 are of greater thickness than those on the section. 4 of Figure 5. lBy reference to Figures 3 to '6 it also will be seen that the web plate 7 of each successive section upwardly of the compound column is of greater Width than the web plate 7 of the section immediately beneath it and that the angles 8 of each successive column section upwardly are stepped outwardly from the angle members o the precedingc'olumn section.

eference to Figures 7 and 8 will show that although the cross sectional areas of the column sections illustrated in Figure 7 are eater than those of the'column sections i lustrated in Figure 8 the wall beams 11, 12 and 13 and 14, the Hoor girders 16 and the lfloor beams 15 of the floor ot' Figure 7 are of exactly the same length as the correspondingmembers on the floor illustrated in Figure 8.

Italso will be seen that the cover )lates 10 on some of the column sections s own in Figure 7 are of greater thickness 'than others in this Figure and that the same is true in regard to the columns shown in Figure 8 and, notwithstanding the differences in thickness of the cover plates and cross sectional area that the columns, in a direction parallel to the webs thereof are of the same width, out to out of the cover plates, while the beams framed to these column sections are of the same length, not only on each floor but, when desired, ma 'be on each of the various floors of hig buildings.

Obviously the colunms of `any one floor may be varied in cross section, to care for differences in the loads on the columns, due

to different paneling, and concentrations on a higher floor, while the columns are all of the same overall dimension face to face plates in a direction parallel to the side "faces of the web plates is maintained the same throughout the entire length of the column, or throughout a series of stories, thereby eliminating lthe necessity of fillers at the splices, and providing a` construction in which the floor girders and other parts connecting to the columns for the entire building or for any de-sired number of 4stories may be of the same length.

Another important advantage is that columns constructed in accordance with this invention will have the outer faces of the cover plates at a constant distance from the face oi the Walls, thus simplifying and' facilitating the placing of brick, stone, terra cotta., or other material of which the Walls are made. A further advantage of this column is that the overalll dimensions of columns constructed in accordance with this invention will be the same on each Hoor and on successive groups of floors, which enables the forms for ireproofing to all be alike and facilitates the placing of fireprooing around columns.

lVhile in Figures 1 to 6 a column is shown made up of four abutting lengths or sections,

in which thedistance face to face of the cover plates is the same in Iall of the column sections, it is not to be understood that in constructing buildings -employing such olumns that the columns need be of the same dimension face to face of the cover plates, in all sections of the column. For' example, say in a building having twenty stories, it will be desirable to make the compound columns for the first ten stories of the same dimension face to face of the cover plates, and to make the columns for the next ten stories smaller, but in which the dimension face to face of its cover plates will be the same throughout the sections making up such column for the ten stories.

W'hile I have described and illustrated only one specific construction of column embodying my invention, various other modilied 'constructions may be made without departing from the scope of the appended claims.
