Tuscania-METAL STRUCTURE..

To all whom it may concern..- l

, Be it known that I, EmuoND MoLLoY, a citizen of the United States, and a resident of the city and county of Ihiladelphia, State of Pennsylvania, have invented n'eW and useful Improvements in Tubular-Metal Structures, of which the following is a specification, rei'- erence being had to the accompanying drawin s.

dy invention relates toa metal structure which is made'r built up of tubular or pipe metal.

. representingl a part The obj ect in view is to rodu'cel a skeleton structure of pipe metal W 'ch shall have its members or "parts united so firmly together as to possess great strength and rigidity.

The metallic structure is adapted for a variety of uses and may be made in various forms, such as a post or column, aegird'er, &c. It is to be understood thatv I do not restrict myself to any particular form or use new structure made in accordance with my invention. m

he invention will be fully described in connection with the annexed drawings, wherein- I f l Figure l is" a sectional view, partly in elevation,v of a -portion of a meta ic structure of my staff used in con.- nection with a member or runner of the tubular stixucture. Fig. 1*- 'is' a sectional plan view of the parts shown by Fig. 1. Fig. 2is a plan view, partly in section, umn made 1n accordance with this invent' ion. Fig. 3 is an elevation, partl ,the post or column shown )y Fig. 2. Fig. 4 is an end elevation, partly in section, of a girder or beam made in accordance with this invention. Fig. 5 is a plan view of the girder or beam shown by Fi .'4.. Fig. 5 is an end view, and Fig. 7 is a p an view, partly in sectionrepresentinv one form of hinged couplingjwhich may be used to connect a girder or earn with a post or column as contemplated by this invention, Y Fig. 8 is a plan yiew, partly in section, of a divided T-coupin imilar letters refer to similar parts throughout the several views, and the letters in the specification correspond to those on drawings.

In Fig. l I have shown a stan" c with tivo plugs o. These plugs, which are preferably made solid and from hardened metal, are provided with shoulders m and lugsm and are receivable stationary in the ends of the pipe.

The outer end of each plug is made tapering,

as shown at p, so as to perform substantially the functions of' a drill or countersink. The ends of the staff a have screW-threaded thereon the Ts b, and concentric with parts of the Ts b are the pipe-irons c. The Ts are connected with the staff a by means of right and left hand screw-threads, so that when the staff a is turned by suitable means .(as Witha Wrench) the plugs o, being stationary in the staii ,Will turn with it and drill into the pipe-irons c sufficiently to make `arigid structure. 1

. The combination of the stad a, the Ts b, and the plugs o constitutes what I have termed a lstem, and the use of the stem will be 4apparent in the description to lfollow. Figs. 2 and 3 shon1 a Wayof combining these stems with pipe-irons as sustaining members to'form a triangular upright. It is obvious, of course, that various other geometrical forms may be constructed in a similar manner. Such an upright is adapted for use-in a su port or post for the girders'or beams. (Sliown in Figs. 4 and 5.)

In Figs'. 4 and 5 I have shown the stems combinedw'ith sustaining members in such a manner as is suitable to form a beam, the shortest side or lower part being thebottom or Weight-carrying part of the girder or beam. In all cases the pipe-irons c arey the sustaining members and are invariably the members running in. the longest direction'in the object to be framed. As seen in Fig. 5, I have placed the stems alternately or in staggered position on the pipe-irons,

and such stems may be as close together as desired, thus enabling the construr-Por to make a girder of suilicient strength to suit the purpose in hand.

In Figs. 6 and 7 I have shown what I term a hinge-coupling d g. T wo oi' these couplings are shown in the upper part of Fig. 3. These Cou )lings form an efficient means of securing t ie girder or beam to a postv where it is desired to support girders or beams by posts only. Thesel couplings, as stated, are hinge-joined and can be 'placed at any desired height and closed on'thepipes over a stem on the post, aspshown. It will be apparent, of course, that the girder shown 1n Figs. 4 and 5 might be used -in any form of structure and could be supported by a Wall or other suitable means just as Well as by the particulariorm oi post which I have illustrat-ed. Inother Words, the girder can be @rder or IOC' . tion- I ,l

Pipe-irons may be lengthened, by short L Without the plugs; but

y tal. It is obvious also that a stal? vvsolly of' shown in Figs. 2v and 3. lt will beappereii-t that the hinge-couplings, es shown in. Eig. 3, may be turned vto receive` the. pipe-irons, (shown in Fig. 5,) thereby connecting the post and girder.,

'In Fig. 8 of the drawings I have shown a hinged Tcoupling which is especially adapted for use in connection with an emergencystem. Said' coupling consists ofconopleinenM tal members l. lz', jointed together at i, and provided with an outside 'thread' .yon its diep branch, said branch beine shown as bi'olten:

away to represent 'an inside thread jf.. iThis T is adapted toclose over a stad andis fastened with a socket. screwed yupon the outside thread of the drop brsnclnwhichenables the regular staff to perform its customsry liu-nc-A closc'nipples on the inside or on the outside by sockets or by butting them. and breelitiug the butt-joints at intervals between the stems. I' y l The stems in many cases may be usci-ul in no esse are they serviceable.

Other pipe-shapedoriiis, Without re crd to size, may be connected andreinioreet by stems 'and made useful, es well es ornamensolid metal would ensiver the saine purpose and the end thereof might be pleinen' tapered.

lt ma i be remarked that a frame having three si es, the runners of which ere psiallel, cannot be other than accurate, since the stems on eachside are all oan equal length. Other accurate useful forms with parellelv runners, though. sides of' unequal area, baving Steins of an. eqiiil length are as easily pron duced.`
