COLUMN FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 360,134, dated March 29, 1887.

Application filed November 8, 1886. Serial No. 218,331. (No model.)

To all whom, it may concern.-

Be it known that I, AUGUSTE BLASER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Columns for Buildings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to improvements in columns for buildings.

The object of my invention is to produce a column or post which can be adjusted lengthwise and used as a means for supporting depressed or overloaded floors in shops or factories, or in old or dilapidated buildings. It is also an object to make such columns as light as consistent with the materials employed, and with a View of making the columns plain or ornamental.

The column proper consists of a metallic shaft, and either a metallic capital or base where there is provision for adjustment as to the whole length of the column, or of a metallic shaft in connection with both a metallic capital and a metallic base, and where there is provision for longitudinal adjustment by making either or both the capital and base adjustable lengthwise of the shaft. The adjustability is provided by forming a thread at the end of the shaft and tapping either or both the capital and base, according to the construction preferred.

It is often necessary to temporarily strengthen floors of warehouses or shops and factories in buildings having a number of stories, and where heavy machinery or materials are tem porarily placed, and in large shops it is desirable, and sometimes necessary, to have as much clear space as possible, and yet at times loads may necessarily be temporarily placed upon overhead floors which would be too great for the supporting-floor to stand, when it becomes necessary for the time being to support the floor from below. Floors are often overloaded and depressed before any provision is made for supporting them, when they must be raised to a level before or at the time props or posts are placed beneath them. In old or dilapidated buildings it is often desirable to level up the depressed floors. Especially is this the case where such buildings are to be repaired for future use as shops or factories. Various expedients are resorted to in raising a floor preliminary to placing supports beneath it.

My improved adjustable column is intended for use in such places, and on account of its adjustability it serves as the tool for raising the depressed floor as well as the supportingcolumn. This is of great advantage in rooms already filled with merchandise or machinery, &c., as in factories. The column is also especially adapted to be moved about within a given locality without taking it down, as may be desirable in construction-shops in providing more room for the passage or setting up of large machinery.

For cheapness I prefer ordinary gaspiping for the shafts and castings for the capitals and bases.

The accompanying drawings show three modifications of my adjustable columns resting upon a floor, f, and supporting a ceiling, 0, the right half of each being in mid-section.

Figure 1 shows a hollow shaft, 1, having a capital, 12, supported by means of a nut, 11, screwed onto the exterior of the shaft and where the latter is screwedinto and supported by a base, 21. Fig. 2 shows a similar shaft, 2, supported by and screwed into a base, 22, and having a nut, 17, screwed onto its top and supporting a capital, 13, having a projection, 19, extending down into the end of the shaft. Fig. 3 shows a similar shaft, 3, supported by a base, 23, and having a capital screwed onto .its top.

The simplest modification is that shown in Fig. 3, where the shaft (piece of gas-pipe) 3 has a plain end, 10, resting within a corresponding recess in the base 23 and upon a flat bearing, 24, belonging to the base. Here the be placed upright, after which the shaft may be rotated (by means of a pipe-wrench) until the capital bears against and supports the ceillng c.

In the modification shown in Fig. 1 the base 21 is hollow and tapped to receive the thread 5 on the lower end of the shaft 1. A nut, 11, is screwed upon the thread 4. at the top of the shaft, and the capital 12, which is hollow, fits down around the end of the shaft and rests upon the upper surface of the nut 11. Here .the base 21 may be put in place, the shaft 1 screwed into the base, the capital 12 placed over the top of the shaft and upon the nut 11, and the column adjusted so that the cap 12 will bear against the ceiling c and support it by turning the shaft 1 within the base 21, or by screwing up the nut 11, or by both operations.

In the modification shown in Fig. 2 the lower end of the shaft 2 has a thread, 7, which screws into the tapped base 22. The upper end of the shaft 2 has a thread, 6, onto which a circular nut, 17, screws, and the latter has an enlarged upper end, 16, upon which the flange 15 of the capital 13 rests. The capital-13 may be hollow, as shown, and has a central part, 19, which extends down into and fits within the shaft 2. 14 represents ornamental parts of the capital. In placing this modification the shaft 2 may be screwed into the base, the nut 17 screwed down upon the shaft, and the capital 13 placed over the shaft and lowered until the part 19 enters thelatter and the flange 15 rests upon the enlargement 16, when the nut 17 or the shaft 2, or both, may be turned and the capital brought to bear against and support the ceiling c.

It is evident that various changes could be made in details without departing from the spirit of my invention. For example, the

lower end of the hollow shaft 3 could rest upon and arounda corresponding part of a base, or it could be tapped and screwed onto the base. The upper end of the hollow shaft could be tapped and the capital could have a part like the part 19 in Fig. 2, threaded and adapted to screw into the end of the shaft.

It is evident that a gas-pipe could have a tapped casting at one end only, and still an- U 2. In acolumn for buildings, the combination of a metallic shaft, a suitable base, a nut,

and a capital, the nut screwing to the upper end of the shaft and the capital being formed to fit and be supported by the nut, substantially as set forth.

- In testimony whereofI affix my signature in presence of two witnesses.

AUGUSTE BLASER.
