METALLIC POST.

SPECIFICATION forming part of Letters Patent No. 551,770, dated December 24, 1895. Application tied. April 29, 1895. Serial No. 547,694. lie model.)

To all whom it may concern;

be it known that I, FERDINAND Jonxsox, a citizen of the United States, residing at New London, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Posts; and I do hereby declarethe following to be a suitici'ently full, clear, and exact description thereof-as to enable others skilled in the art to make and use the said invention. p

This invention relates to posts for fencing and the support of lamps, lanterns, electric insulated lines, &e.', and has for its object cheap production of light and substantial posts. by combining metallic bars with bracing-plates in such a manner as to adapt them to. be readily planted in the earth or concrete foundations, and when planted to resist the usual disturbing causes; and to this end it consists in the art of attaching plates transversely to metal bars, or thereby uniting two or more metallic bars by such plates so as to brace each other, and the forming by such post.

' transverse plate..- Fig. Qshows a like View of transverse plates a means of driving such posts into the earth, and of securing them when so planted.

I will now proceed to particularly describe the mode of making and practicing thisinvention, referring in so doing to the accompanying drawings, which- Figure 1 shows an elevation of a single post; Fig. 2, an elevation thereof as bent to better secure it in the earth. Fig. 3 shows a double Fig. 4 shows a quadruple post. Fig. 5 showsa plan view of Fig. 1; Fig. 6, a detached view of the transverse plate on Fig. 1 before said plate is attached to the upright post. Fig. 7 shows. a section of the post in the plane immediately above the point of attachment of the plate. Fig. 8Ishows a section of the twin post shown in}! lg; 3 immediately above the the quadruplepost in section at the same part. Fig. 10 shows detached view"'of=.=a,plate for quadruple pbs s. Fig. 11'- shows a'fdetached. viewofa plate fora triple post. i Fig. 12 shows the die and punch for piercing the plates. .Fig. 13 is a tool for attaching cross-plates to the posts, and Fig. 1a taperspectiveyieW of a quadruple'tapering post. i W The posts in these several instances are made of what are known as. rolled shaped irons or steel, and may be of any of the usual forms of angle, channel or .1: forms of crosssection. The horizontal plates are made of fiat pieces of ductile metal,and have apertures punched in them, with a tongue raised in the act of punching, which being set back again into flatposition impinges strongly against the upright bar, and by corrugations made in the web of the upright bar, at points intermediate between the edges of the post, above and below said plate, lock the plate against any cndwise motion on the post, and against any bending of the tongue in the plate from the flat plane to which it has been forced in attaching it to the post. Several of these plates may an oblique direction and in some cases it may be done preliminary to driving, thus aitordin g a'resistan'cc to the lifting of the post out of the earth. as in the'case of line-posts 0t fences for inclosures for cattle-grazing grounds.

Referring to the drawings, 1 represents aflanges or edges thereof; 5, the transverse plate 6, the aperture in the transverse plate; 7, the tongue in such aperture, which tongue 7 is made of such dimensions as when raised that it leaves an aperture adequate to pass the post, and when pressed downwardly it impinges upon the web 2 of the post 1, and is slightly upset orcompressed in. so doing.

plate 5 is done by a die, (shown in Fig. 12,)

- which has the portion of the die 11 (marked 10) raised above the plane of the rest, and the be attached to posts when of considerable upward in the cutting or' punching process The piercing or punching of the holes 6 in the ing operation, and then the driving is done in post; 2, the web of the post; 3 and 4, the

punch 12 cuts the web upon this raised por :3. A post consisting of two or more vertical, tion 10 of the die 11 with a shearing action or iln-linedbarsof shape rolled metal, a transand curls it upward before completing the aperture and expelling the waste metal or scrap through the die 10. The corrugations in the post 1 to retain the plates 5 in position are made by a compressing-tool (shown in Fig. 13 in detached View) in which there are grooves or corrugations 13, which grasp the web 2 of the post 1 and bend itinto corrugation It above and below the plate 5, so that the inner and outer margins of the hole t in the plate 5 have a portion of the web 2 bent outward and inward pressing and firmly resting upon them.

The same operation of applying the implement shown in Fig. 13 may be made to bend the tongue down into the flat position, so that a single operation answers to attach the plate 5 to the post 1. The upperends of compound or multiple posts may be either fastened by rivetingor bolting or may be made by simply bending a single bar over upon itselt, so as to form two post-s from the same bar, or they may be secured to each other by any of the head or cross pieces required for use in supporting lamps or electric insulating devices.

Having described my invention and the operation thereof, what I claim is 1. As an article of mahufactnre a post. adapted for fencing and like uses provided with transverse braces, fitted in contact with both the internal and external surfaces of the post and secured by the impingement of the brace upon opposite sides of the bar or bars I forming the upright of such post and by eorrugations formed in the central part of the I breadth of the upright bars above and below therein with tongues compressed against the bars, and corrugations in said bars, resting upon the sides of the transverse plate substantially as and for the purpose set forth.

lost s formed of two or more strips or bars of shape rolled metal with a series of plates of execssivel y tsmaller length and breadth scoured transversely thereto by perforations provided with tongues compressed against said bars, and secured in position longitudinally on said bars b'ycorrugations formed in the web of said bars upon opposite sides of said transverse plates, forming as assembled tapering compound columns ofsaid bars, with transverse plates substantially as and for the purpose set forth.

4. The combination of one or more posts Formed of rolled shaped metallic bar with a plate transversely secured thereon by a tongue of metal formed integrally with said plate, and forced into flat plane therewith and into tirm impiugementupon said bar substantially as set forth.

5. The combination of one or more posts formed of rolled shaped metallic bars with a transverse plate or plates fitted to make contact with both the internal and external surfaces of said bar or bars and secured inposition by corrugations of portions of the center of breadth of said bars contiguous to said transverse plate or plates substantially as set. forth.
