COLUMN.

Specification of Letters Patent.

a atenteu only 17, 1906.

To all whom it may concern:

Be it known that I, FREDRIGK P. ANGELL, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Columns; and I do hereby declare the following to be a full, clear, and exact description thereof, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, wherein Figure l is an elevation, partially in section, of my improved column. Fig. 2 is a cross-section of the column. Fig. 3is a crosssection of a column and shows an iron band about the same for holding together the staves comprising a column preparatory to stapling. Figs. 4 and 5 are types of staples having points disposed atright angles to their body portions employed for securing together the staves comprising a column. Fig. 6 is a modified form of a barbed strip employed for the same purpose. Fig. 7 is a perspective view of a staple having diverging points, and Fig. 8 is a cross-section of a part of a column and shows a dowel-pin inserted between the adj oined edges of the staves comprising a column.

My invention contemplates the use of a series of staves having at least one of their ends tapered and the abutting edges of the staves machined on axial lines so that when placed together they will form a round or cylindrical shaped column, the same being held together by means of metallic staples striding .the adjoined edges of the staves and driven within the same from the interior wall of the column to secure the column together.

Usually in constructing a 'staved column the staves near their edges have been provided with longitudinal kerfs adapted to receive bonding means of wood or metal, and in either instance the wood is weakened along the adjoining edges where the staves unite, owing to the kerf running the whole length of the staves. My invention is designed to overcome this objection and to construct a column very stout and rigid, whereby but little lumber will be necessary in their construction, whereby the same will be tasty and neat in design and appearance, and whereby the same can be expediently and economically manufactured.

In the drawings like marks of reference refer to corresponding parts throughout the different views.

A represents the column, B an iron band for securing together the staves comprising a column until stapled, and C staples such as are employed for securing together the adjoined edges of the staves comprising a column.

The column comprises a series of staves a, having an arc-shaped exterior and a wedgeshaped cross-section, as shown. These staves are uniformly tapered along their upper edges and their edges may be fluted or corrugated and capable of interlocking when placed edge to edge within a column, the edges of the staves being machined on axial lines, so that when the staves comprising a column are together the column will present a round and even surface.

In Fig. 8 I have shown a dowel-pin b, inserted. within holes 0, bored within the edges of the staves a. The holes 0 are disposed along the edges of the staves in such manner that when the several staves comrising a column are placed edge to edge the lioles will be oppositely disposed, so that dowel-pins placed therein will interlock the staves so assembled. By the use of the dowel-pins corrugating the edges of the staves may be dispensed with, as the pins prevent the staves from lateral displacement. After the staves are set up to form a column metallic bands or rings B are fitted over the same to secure the column together until the several staves have been connected along their edges by means of metallic staples C, driven so that the barbs thereof will engage the adjoined edges of the staves comprising the column and secure the same together. These staples are driven from the interior of the column at intervals along the edges of the staves, as shown in Fig. 1, until the several staves comprising the column are stapled together. The bands or rings B are then removed and the column sanded and smoothed ready for use.

In Fig. 6 I have shown a modified form comprising a barbed strip D for securing the edges of the staves together. This strip could be used in sections containing three or more barbs or could be used the whole length of the column, as deemed expedient.

In Fig. 7 I have shown a staple having four points set divergingly and in such manner that one point of each end of the staple will lean toward and one point away from its body portion. By this provision as the points are forced into the wood they will be still more diverged and not only tend to firmly draw the adjoined edges of the staves together, but will also be prevented from loosening from their anchorage, as will be readily comprehended. in Fig. 8.

In lieu of a four-pointed staple it would also be apparent that a staple having two points would answer well for the purpose, provided its points were disposed either to diverge or converge from their body portion in such manner that when driven into the wood the points would exert a tendency to draw the adjoined edges of the staves together.

I would not be understood as confining myself to any particular form of staple for securing the edges of staves together nor to the particular shape of the column shown, and. I hold myself entitled to any and all changes in the form and minor details that would be compatible with the spirit and intent of my improvements.

Having, therefore, described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a tubular column, the assemblage of staves joined together at their edges and me tallic staples overlapping the adjoined edges of said staves and driven Within the same from the interior of the column to secure said staves together.

2. In a tubular column, the assemblage of staves joined together at their edges and metallic staples overlapping the adjoined edges of said staves, said staples having double, oppositely disposed barbs at either end thereof driven within said column from the interior thereof in such manner that, said barbs will diverge when. driven, and. bind the edges of said staves together.

3. In a column, the assemblage of staves having oppositelydisposed holes formed within their edges and dowel-pins inserted within said holes and adapted to connect said staves together, and metallic staples overlapping the adjoined edges of said staves and driven within the same from the interior of the column to secure said staves together.

4. In a column the assemblage of staves unitedly oined together, anda metallic strip having barbed points adapted to overlap the adjoined edges of said staves driven therein from the interior of the column to secure the same intact, for the purpose set forth.
