Specification of Letters Patent.
Application filed October 19, 1910. Serial No. 587,794.
To aZZ whom it may concern:
Be it known that I, LAURENCE S. LACE- MAN, a citizen of the United States, and'a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Poles, &c., of which the following is a specification.
This invention has relation to open-work or skeleton structures, such as are suitable for use as poles for carrying, for example, telegraph wires,-telephone wires, overheadtrolley wires, electric lighting wires, masts, staffs, columns, towers, beams, girders, concrete reinforcements, and a variety of other purposes: its purpose being to provide an open-work or skeleton structure formed of metallic elements integrally united with each other, and having its elements so formed and disposed that the structure will have maximum strength while being comparatively light, and may be most economically produced.
This purpose and others which will appear from the hereinafter description are secured by the construction illustrated in the accompanying drawings to exemplify what is at present regarded as very desirable forms of the invention, but to the de tails of which the invention, in its broad aspect is not restricted.
In the drawings:
Figure 1 is an elevation of a structure embodying the present improvements.
Fig. 2 is a transverse sectional view on the plane of the line 22 of Fig. 1, drawn on a larger scale than Fig. 1.
' Fig. 3 is a view in transverse section, showing a slightly different structure embodying the present improvements.
Fig. 4 is a like View of another form of structure embodying the present improvements.
Fig. 5 is a like view ofstill a difi'erent structure embodying-the present improvements. V Fig. 6 is a like view of another form of structure embodying the improvements.
Fig. 7 isa like view of a form whereof the structure of Fig. 5 is a unit instead of the complete article.
Fig. 8 is a like view whereof the structure shown in Fig. 6 is a unit instead of the complete article. 7
.Fig. 9 is a like view showing a structure composed of specifically different members from those preceding, and embodying the present improvements.
F lg. 10 is a like view showing members substantially like those of Fig. 9, but dit' ferently arranged, in accordance with the present invention.
Fig. 11 is an elevation of a structure' embodying the specific form of elements shown in Fig. 9, said Fig. 9 being taken on line 9 of Fig. 11. I
The same characters of reference designate the same parts in the several views.
The present structure comprises one or more longitudinal members, each having a plurality of portions which face in different directions and are adapted for weldable union electrically with other members placed 'members also may be variously arranged with relation to each other and to the longitudinal member or members and may be of various numbers or sizes, to accord with requirements of various structures which embody the present invention. Thus, for example, thcre may be a series of the side members on each side of the structure, and these members may be arranged transversely, diagonally, or both, of the structure, or otherwise as desired, within the broad spirit of the invention.
Various forms of longitudinal members and various relative arrangements of longitudinal and side members are shown, but it is not intended to restrict the invention to these particular forms and arrangements, although they are preferred.
The illustrated forms of longitudinal members include a star-bar, marked 20 in all the forms where it appears, a Tbar, marked 80, wherever it appears, a Y-bar, marked 40 Cit an example and is marlred 50. Other forms of such members suitable for the purpose of the present invention will readily suggest themselvesv The side incmbersare marked 120 wherever they appear. in all of the herein exemplified forms of the in- Yention flat strip is suitable for weld-able union with the longitudinal members, and as such strips are desirable for use in the present structures this form of side members is shown in all the accompanying figures of the drawings, though other forms may be employed, ifprcferred. In Fig. l a skeleton structure, rectangular in cross section, is shown as composed of a series of spaced side members on each of its sides, connected with each other by longitudinal members arranged in the angles of the structure. The side members are spaced apart along the length of the longitudinal members and the longitudinal members have separated welding places, hereinafter particularly de-= scribed, at which they are integrally united to the side members by electric welds. These welding places on the side members face' in different directions, each longitudinal member therefore being wcldably united to the side members on two difierent sides of the structure. In this particular exemplifica tion some of the side members, on each side of the structure, extend transversely of the structure while others extend diagonally and cross each other. The structure thus formed is comparatively light. may be inexpensively produced. and has the utmost strength and du ability. liloreorer, it may be easily transported and will withstand wind stress as well as all other strains and stresses to which it may be subjected in use. Again, the structure is such as to permit convenient access to the electrodes or terminals employed in the welding operation. to all of the intersecting portions, and toe relative disposition of the members is such as to permit the structure to be supported by the table used in welding and to be moved along'such table as the welding operation progresses. This materially contributes to the ease with which the structure may be formed and proportionately reduces the expense of such structure.
ll hile the rectangular T ture is a desirable one, yet it cross sectional shape, including other of polygons as well as round or rounded shapes.
in the particular esemplification shown in I Fig. l, the longitudinal'me nbers are cornal .b 9% U r T n a a' '"n poser. 01 star ars a i ,n lei niches tv F 1g. 2 1s will be noted t. she members 1120- are each weldai united to the edges of two adjac s of the for eldin places the each other, and the shape of the star-bar is such that its limbs face in different directions so as to present welding places 21 to side members arranged at an angle with each other.
The form exemplified in Fig. 3 is substantially like that already described, except that it employs l -bars in the angles of the structure, as the longitudinal members, in stead of star-bars.
l ig. l shows a trianguular structure whose longitudinal members are formed of i-bars l0 arranged in the angle thereof and connected with each other by side members 12c.
In Fig. 5 there is shown a rectangular structure wherein the body is formed of a star-bar whose limbs extend of the cor ners of the structure and have their edges weldably united to the surface of the side members which are connected with each other, in this form, by said star-bar.
in Fig. 6 a triangular structure is shown, composed of a (-bar it) which extends longitudinally thereof, and the side members 120 are connected with each other by a "Hoar and have their surfaces welded to the edges of the latter.
in the form shown in Figs, 5 and 6, the
members referred to form the complete structure, but, as exemplified by Figs. 7 and 8 they may form corners of structures, certain of the side members 1'20 being prolonged from one side to the other.
in Figs. 9 and 10, various relative arrangements of channel bars with transverse members are exemplified. Thus in Fig. 9, the transverse members, 120, are disposed outside of the channel bars and the transverse bars are welded to the edges thereof, while in Fl 10, the channel bars are outside the transverse members and the latter welded to the surfaces thereof.
tlbriously, it is not wholly essential to the invention considered in its broadestaspects that there be side members on all sides of the structure.
It will be apparent to those familiar with the art of electric welding that the relative disposi ions and forms of the members herein described are such as to adapt the mems to he weldably united with each other ir places of contact, and the mode of like welding, will, it is thought, be apparalso to such persons. Therefore it is be unnecessary herein to explain anner of prodi'icing the welds or to the means therefor, further than to hatthe contacting portions of the metal are reduced to a plastic condition by an electric current passing therethrough, and the moleeul re caused to. coalesce by presis for producing this current welding places 21 are separated from y and for applying it and press- .which the side members are disposed; and
also to the fact that while the forms shown in Figs. 9 and 10 are specifically a form of channel bar, and have been so described herein, yet the other illustrated forms also are such as substantially to provide channels extending longitudinally of the members between the limbs, and hence the term channel when used in the subjoined claims is employed in a full generic sense and unless,
otherwise defined, is not intended particularly to relate to the form which has hereinbefore been referred to as a channel bar. The members 120 may be provided with welding projections. These projections are shown on the horizontal members as continuous ridges which are marked a. The projections on the diagonal members are marked I). It is understood, of course, that these projections rest against the vertical members and that said members are welded together by these projections.
Having thus described the invention what I believe to be new and desire to secure by Letters Patent, is:
1. A corner connection for skeleton frame Work, comprising a corner member and side members, the corner member having three or more radially extending limbs 0rv flanges, the side members being united to said limbs or flanges in pairs on contiguous sides of the corner member, each point of contact between the side members and corner member being a spot weld.
2. A structure comprising a plurality of longitudinal members and side members connecting the longitudinal members with each other, said members being relatively arranged to form a polygonal frame having the longitudinal members in the angles thereof and each of said longitudinal members having limbs which extend in difierent directions from a common center, the edges of the limbs being in contact respectively with the adjacent side members and electric welds integrally uniting the contacting portions of the longitudinal and side members with each other.
i 3. A structure comprising a plurality of longitudinal members, side members connecting the longitudinal members with each other, said members being relatively arranged to form a polygonal frame having the longitudinal members in the angles thereof, each of said longitudinal members having limbs which extend in different directions from a common center, tWo of the limbs being in the same plane, the edges of the limbs being in contact respectively with the adjacent side members, and electric welds integrally uniting the contacting portions of the longitudinal side members with each other.
4. A structure comprising a plurality of longitudinal members, side members connecting the longitudinal members with each other, said members being relatively arranged to form a polygonal frame having the longitudinal members in the angles thereof, each'of said longitudinal members having limbs which extend in different directions from a common center, the limbs being arranged to extendopposite each other and in the same plane with each other, the inner edges of the limbs being in contact respectively with the adjacent side members, the outer edges of the limbs being in contact respectively with bars joining the same, and electric welds integrally uniting the contacting portions respectively with each other.
In witness whereof I have hereunto set my hand at New York, county of New York and State of New York, this lith day of October, 1910.
