' plates of metal each. rovided with a central Be it known that I, MAURICE LAOHMAN, a\ opening'3. By re erencethe plates 2 are citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fenceposts, of which the tlon.

My present invention relates to the construction of skeleton metal posts or poles conlilprising intersecting members secured toet er. i g The inventioh is particularly useful in the construction of fence posts owing to the simplicity and beauty. of the structure when completed.

The object of the invention is to. provide a simple, strong, ornamental, and at the same time, a cheap post for use in fences and for other purposes.

The invention consists in the improved post construction hereinafter. more particularly described and then specified in the claims. a

In the accompanying drawings, Figure 1 is a side elevation of a fence post constructed in accordance with this invention.

Fig. 2 is a transverse cross-section taken on the line 22 Fig. 1.

Fig. 3 is an enlarged front elevation of one of the upright members showing-the manner of preparing the same at the point of intersection with a transverse member.

Fig. 4 is an enlarged front elevation showing one of the points of intersection between the upright and transverse members before applying the welding button.

Fig. 5 is an enlarged plan view of the weldlng button and Fig. 6 a central crosssection through the same.

Fig. 7 is a transverse section through one of the intersections between the members showing the completed joint, the section be- 7 ing taken on the line 7-7 Fig. 4.

In the drawings, 1 indicates the upright members preferably arranged parallel with each other and of which there may be any number desired while 2 indicates the transverse members any desired number of which are provided in spaced relation and 'arranged to intersect theupright members 1 at the desired intervals. g

The uprights l are preferably T-shaped in cross-section while the m m rs. 2 a e following is a specificasquare 1n form a though they maybe of any desired shape in contour and the material thereof 18 of a thickness approximately equal to the thickness of the web T-shaped uprights 1.

The uprights may engage theiplates' at portion of the any point about the periphery thereof but with a slot to take the web of the uprightas shown.

Certain portions of the flanges of the members 1 at the points of intersection with the plates 2are cut away as shown in Fig.

3 to leave a restricted mass 4 isolated from the flange and which is practically a bringing forward or exposing ofv the web of the T. This is effected by forming openings 5 in the flanges at each side of the web of a length to leave a short portion ofthe web exposed at the point 4. By preference the openings 5 do not extend to the outer. edges of the flanges for the full length of the openings but only sufiicient metal is re-- moved at the edges of the flan es to provide openings 6 as wide as the thickness of the transverse plates 2 so that when the web of the upright isinserted in the slot in the plate 2 the squared corner of the plate is permitted to be brought forward in the openings 6' until the edge is flush with the outer face of the'upright membersyl, the outer ends 7 of the flanges bearing on the opposite surfaces of the plates 2 as shown in Fig. 4 to prevent any tendency of the members to rock relative to each other. By this formation the squared corner or edge 8 of the plate 2 is brought into the same plane as the outer edge of the exposed web 4 and the'intersecting edge 8 and exposed web 4 form a cross thearms of which are of equal thickness.

9 indicates a welding button preferably in the form of a disk provided withan annular ridge 10 intermediate its edge. The

ridge 10 is of such diameter that when the K is such that it will conceal the openings 5 in the member 1 and is preferably coextensive with the width of the flanges of the uprights 1. It will be understood that the weldingbutton 9 may be of any desired shape or contour for purposes of ornamentation.

The button 9 is placed over the intersection of the members 1 and 2 so that the rid e 10 intersects the parts 4 and 8 as previous y described. The points of intersection of the ridge with the parts 4 and 8 form isolated points of contact which allow the parts to be readily and quickly joined by the electric welding process.

To electrically weld the button 9 to the members 1 and 2, the parts are held between the electrodes of a suitable electric welding machine and current is passed from one electrode to the other through the work at the same time pressure being applied, preferably through the electrodes, to force the parts'together and complete the weld. As the electric current passes from the members 1 and 2 to the button 9, the points of isolated contact formed by the intersections of theridge 10, exposed web 4 and edge 8 soften and by the application of pressure coalesce with each other and form four points of welded union at each joint, the points at which the welded unions take place being indicated at 11 in Fig. 4. It is thought that any further description of the electric welding action is unnecessary, the process being now so well known and universally practised.

As indicated in Fig. 7 the slot formed in the plate 2 to take the web of the-uprights 1 is preferably of less depth than the web and the web is provided with a recess to allow for the short slot and to form shoulders 12 which engage opposite surfaces of the plate 2 and lock the upright 1 against any tendency to longitudinal slippage.

It will be understood that the shape or design of the post as well as its parts and the details of construction may be varied Without departing from the spirit of the invention as expressed in the appended claims.

What I claim as-my invention is "1. A metal post. comprising T-shaped'upright members, transverse plates inter-' secting said members at spaced intervals and having the Web of said membersseated in arecess thereof, the flanges of said members being removed at the intersection to expose theweb and whereby the edge of the plate is brought into the same plane with the outer surface of the upright and a ridged button" havin the ridge thereof welded to the edge of the plate and the exposed web of the upright to lock the members together.

2. 'A metal post comprising T-shaped upright members, transverse plates intersecting said members at spaced intervals and having the web of said members seated in a recess thereof, the flanges of said members being removed at' the intersection to expose the web and whereby the edge of the plate is brought into the same plane with the outer surface of the upright and a ridged button having the ridge thereof welded to the edge of the plate and the exposed web v of the upright to lock the members together, the outer edges of the flanges of the uprights engagmg opposite surfaces of the plates.

Signed at New York, in the county of New. York and State of New York, this 28th day of December, A. D'. 1915.
