This invention relates to a method of making columns.
This invention further relates to the making of columns having either a straight,
5 taper or an entasis, and is especially adapted 'to the xpaking of columns which are to be used as flag poles or the like, and the prin-' cipal object of the invention is to provide an improved process of forming such columns. A further object of this invention is to "provide an improved method of making a column in sections which may be assembled without the use of rivets or bolts and yet have in its finished form a smooth curvature .15 or taper from end to end without breaks in the contour thereof. I
Columns which are first fabricated in sections, and later assembled without the use of rivets or bolts, have been known in the art. 'These, however, have usually been of the type in which the adjoining ends of the sections are telescoped with respect to each other, and they are open to the objection that the finished column does not have in the tapered line appear at the points where one section telescopes into the other. These columns are further objectionable on the ground that it is practically impossible to form a column having'a straight tapered appearance by giving the column the proper entasis. i In the manufacture of steel flag poles, a wide variety of sizes is called for, including varying lengths varying diameters at several points along the respective lengths, and varying thicknesses of the walls at different points in the respective lengths of the poles.
Attempts have heretofore been made to construct tapered flag poles from sheet metal by initially cutting the metal tothe necessary trapezoidal shape, and thereafter forming the same into the tubes from which the pole is built up.
, Such poles, however, as have been'so constructed have not been well received in the trade, as they have necessarily been made in but a few sizes, and, owing to shop limitations the same have been made with relatively thin walls, and of too. large diameters, to render them acceptable except under certain limited conditions.
..,.,;To attempt to manufacture flag poles a smooth taper, but, on the contrary, breaks ,in conventional detail two abutting se variety of lengths, diameters at several points along the respective lengths, and wall thicknesses throughout the respective lengths, as called for in the ,trade, wouldrequire an expenditure for shop equipment which would be prohibitive.
These and other dificulties have been overcomeby the improved method of formmg columns of the type herein described.
More specifically stated, one of the objects of this invention is to provide an improved method of making a column which will have a smooth, cdntinuous taper. V
'A further object of this invention is to' provide an improved method of making an assembled column which may, if desired, be formed with the proper entasis to present a pleasing appearance. .n. I
A further object is to provide an improved method of making an assembled column which will be practically, a onepiece strudture after completion."
TENT/OFFICE- A further object is to provide an improved method of making al column for use as a flag pole or the like in which the wall thick-' ness may be varied throughout the length to provide the greatest possible strength with a minimum of weight.
A further object is to produce an improved method of making an assembled column for use as aflag pole or the like which column will possess unusual strength,
durability, and be practically a one-piece structure after completion, and which may be economically made.
The nature and characteristic features of my invention 1 will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which: i
Figure 1 shows a finished column, in this case intended for use as a flag pole;
Fig. 2 is a perspective view of one of the sections making up the columnand also showing the first step in the process of forming the column-;'.
Figs. 3, 4 and 5 are views similar to 2, but of sections of successively smaller 1n1- tial diameter than that disclosed in Fig. 2,
the. same being used for forming the progressively-smaller sections of the column;
ons l as Fig. 6 is a fragmentary section shcing.
andmeans for uniting the same, as w .the reinforcing means" preferably used to strengthenthecolumn at the points of junc ture ofthe sections;
Fig. 7 is a .sectiontaken on the line 7-7 ofFig.6;
Fig. 8 is a fragmentary section showing .in detail 'twoabutting sections and a modi- I fied' form of reinforcing 'mea ns used to Fig. 8; and
strengthen the columns-at the points of juncture of the sections;
Pg. 9 is a section taken on the line .99 of "Fig. 10.is .a'n end elevation 'of'oneof the sections in the swaging blocks ,used for formlng-the sections atone stage of the proc- 'ess.
' Referring to thedrawing, inthe' particular embodiment of my invention therein shown, 1' denotes a. column which may be composed are .single tubularsection, or a plurality ofsections 2, as the c'ase may require in eaeh particular instance.
I beveled or cha-mfered'as at. 3. Each section is also preferably provided with a plurality The ends of each of the sections I are of aperturest near the ends thereof.
Reference numerals5 and 6 refer to' reinforcing means which may be used to. strengthen the column at the points of uncture of the different sections'-numeral' 5 referring to structural angles, while reference numeral 6 designates tubular reinforcing readily procured the market in stock' Having described the component parts of the applicants device, the method by which itisconstructed will now beset forth.
- The. starting point is a tubular section,
preferably a length of pipe suc-h as may be sizesand-various thicknesses. If the column desired is below a certain height, only one.
section is necessary; otherwise aplurality of sections are "used. I 1
A slot 7- is first cut in the tube. This slot .is of elongated V-shape, and if the column is to be given an entasis, the edges of the slot are correspondingly curved. The cut ting is preferably .done by means of an acetylene cutting torch, although, of course,
it willbe understood that'oth'er 'means for cutting the slot may be employedif desired.
After the slot of the desired shape iscut in the tube, the tubeis then placed in apress (not shown) between swaging blocks 88,
' and swaged to. bring-the margins of the-slot together, the tube being constantly turnedduring the swaging operation, as well as being moved lengthwise, thereby to close/the slot and form the tube'into the proper tapered sh'apej" After the margins of the slot have thus been brought together, and the section of the column formed to sha e, the
adjoining edges of the slot are then welded together, preferably by means of the well 'known arc welding process, although here again'it will be understood that other means may be done in the shop or on the field. The
which requires 4 and welded toone end of the section,- prefera-bly'l'by filling up the holes 4with metal deposited by the arc welding process. This sections are now fitted together as. shown-in" Figs. 6" or 8, and welded :both at the point of juncture 3 and at the remaining holes 4.
This welds the sections directly to each other, forming a unitary column, and also Welds the sections to the reinforcing means,
thus strengthening. the column at the junction point. I
The above disclosure; scriptive .of a typical illustration-of the invention, but it should, of course, be understood that manychanges may be made with out departing from the'spirit of the invention. For instance, reinforcing means different from those disclosed may be used, or
is intended as dethe reinforcing means may be. omitted -en-,
tirely in some instances, yet the column will be strong enough for the use intended. Or the column may be used for other purposes than a. flag pole.
