" This invention relatesv to metal structures, such as oil well derricks, towers of various types, building structures, `bridge piers, etc.l

The general object of the invention` is to provide van Iimproved metalY structure of the character stated, which may-be quickly erected or taken down. Y

Another object isto provide a sectional metal structurercomposed of tubular members detach?-V ably fitted and held together by slip joints, which permit a rapid'drop-in assembly and a fast dismantling of the structure. v

Another object is to vprovide a sectional metal structure composed of tubular members fitted and held together by slip joints, one member of certain joints being welded to certain of said tubular members.

` Another object is to provide a metal structure which is considerably stronger and more rigid than an angle-iron'oil Vwell derriok, and which offers Vless resistance Vto' wind, thus enabling the structure to withstand the heaviest'wind storm. Another object is to provide a structure of the character` stated which may be constructed of new or used pipe, such as oil well drill pipe.

A further object is to provide a metal structure `which will effectively resist fire, so that its members, after beingbent and twisted out of shape by the action of heat, may be'readily bent back into shape and used over again in reassembling the structure,thus effecting complete salvage of the structure from re. Y Other objects and advantages will appear hereinafter. f

Fig. 12 isa longitudinal section of oneof the tie rods.' i Figs. 13 and 14' are horizontal sections of modified forms of slip joints. v

Corresponding` parts are designated by the same reference characters in all the figures of the drawings. My structure primarily comprises -metal legs I, ygirts 2 and tie rods 3 of tubular form, which may be constructed of pipe, such as new or used oil :well drill pipe.

The legs lare detachably connected together j end-to-end by slip joints 4, as illustrated in Fig.

6, or by slip joints 5, as illustrated in Fig. 'l of the drawings, to form the corner posts |00 of my structure. t Y A iEach `of the slip joints li comprises a short such diameter as to fit closely within the legs I, and the upper portion of said piece of pipe 6 is tted within and welded to the lower end portion of a leg I, there being holes 'I drilled through the lower portion of said 'leg and the upper vportion of said smaller piece of pipe 6 to facilitate weldingV thereof together, the welding material filling said holes and pinning said piece of pipe to said ieg. The lower portion of the piece of`pipe which'projects below the lower -end of each leg`I forms the male member 8 of a slip joint V4;

while the upperend of each leg I forms the female member 9 of said joint, and the lower end of one leg -I is detachably connected to Ythe upper end of another leg by inserting the male member 8VV within the female member 9 of the ejoint 4, until the lower end of `the upper leg rests upon the upper end of the lower leg as illus- -trated in Fig.f6 of the drawings.

Each of the joints -5 is formed by taking a sec- "tion of oil well drill pipe I0, which has its wall thickened at its end as at I I', for cutting a thread -therein, and reducing the external diameter of said thickened end, as indicated at I2, to form the male -member I3 of said slip joint 5, the female member-I4 ofV saidjjoint being formed by the other end of a leg formed of a section'of 4drill pipe. The reduced end portion I2 of the pipe I0 provides an annular external shoulder I5 on the leg I, which is formed by said pipe at the upper end of said reduced end portion. The lower end. of one leg I is detachably connected, by means of slip joint 5 to the upper end of another leg I, by inserting the male member I3 at the lower end of an upper leg into the female member I4 at the upper end of a lower leg until the shoulder I5 of the upper leg rests upon the upper end of the lower leg.

The girts 2 extend horizontally across the sides of the structure and are each detachably connected at their ends to a pair of legs I at one side of the structure by slip joints I6, which joints comprise sleeves I1, and the ends I8 of the girts, which ends are bent downwardly to fit in said sleeves, said sleeves being welded to the inner sides of the legs I at the upper ends thereof and about midway between the lower and upper ends of said legs. Pins I1 are secured in the lower ends of the sleeves I1 and the girt ends I8 are provided with slots I8 extending upwardly from their lower ends to receive said pins when said ends are slipped into said sleeves whereby my structure is heldV rigid against twisting. The sleeves I1 may be formed of short pieces of drill pipe.

The tie rods 3 are arranged in pairs extending diagonally of the sides of the structure across each other, with their lower ends connected to the upper ends of a pair of legs I by connections I9, and with their upper ends connected to the next upper pair of legs near their upper ends by connections 20 immediately below the connections IS. Each tie rod 3 may consist of a main member 2| of small pipe, and

short end members

22 and 23 of smaller pipe or rods driven respectively partway into the lower and upper ends of said main section and extending beyond said ends, the portions of said

end members

22 and 23 within the main member 2I being welded to said main member. The outer end portions of the

Aend members

22 and 23 of the tie rods 3 are provided with

threads

24 and 25 respectively to be engaged by

nuts

26 and 21 respectively. Each connection I9 comprises an angle iron 28, a threaded lower end member 22 of a tie rod 3, and a pair of nuts 26 engaging said threaded end member. One member of each angle iron 28 is'welded to the outside of a leg I at the upper end of said leg, while the other member of each angle iron 28 is apertured to permit the lower end member 22 of a tie rod 3 to extend therethrough, the nuts 26 on said lower end member engaging the opposite sides of said other angle iron member. Each connection 20 comprises an angle iron 29, a threaded upper end member 23 of a tie rod 3 and a pair of nuts 21 engaging said threaded end member. One member of each angle iron 29 is welded to the outside of a leg I near the upper end of said leg immediately below an angle Yiron 28, While the other member of said angle iron 29 is apertured to permit the upper end member 23 of a tie rod 3 t0 extend therethrough, the nuts 21 on said upper end member engaging the opposite sides of said other angle iron member. By turning the

nuts

26 and 21, on the threaded

end members

22 and 23 of a pair of tie rods and causing the inner nuts to disengage and the outer nuts to engage the

angle brackets

28 and 29 through which said end members extend, the tie rods may be drawn taut between said angle brackets for tying a pair of legs I to the next lower pair of legs, and bracing the structure. 'Ihe inner nuts may then be turned against the inner sides of said angle brackets for locking the tie rods taut between the brackets at the ends of the rods, in position tying together two adjacent pairs of legs, and bracing the structure.

My structure, when adapted for use as an oil well derrick, is constructed with a. window 34 at one side, at the lower portion thereof, to accommodate the walking beam of an oil well rig.

Said window comprises a horizontal up-per girt member 3l, a pair of upwardly converging girt members 32, and a pair of horizontal girt members 33, all of which being constructed of tubular metal such as pipe. The upper ends of the converging girt members 32 are welded to the under side of the girt member 3I intermediate the ends thereof. The horizontal girt members 33 are welded at their inner ends to the converging girt members 32 intermediate the ends thereof. The window 30 is detachably connected, at the ends of the girt 3|, and

girt members

32 and 33, to legs I, by. slip joints I6. The girt member 3| is constructed like the girts 2 with depending male joint members I8 at its ends which slipinto the female joint members or sleeves I1 welded to the next lowermost legs I, intermediate the ends of said legs. The converging girt members 32 are formed at their lower ends with depending male joint members I8 which slip into the female joint members or sleeves I1 which are welded to the lowermost legs I intermediate the ends thereof. The short horizontal girt members 33 are formed at their outer ends with depending male joint members I8 which slip into the female joint members I1 which are welded to the upper ends of the lowermost legs I. The upwardly converging girt members 32 provide a space 34 in the lower part of one Side of the derrick, through which space extends the walking beam of an oil well rig.

When adapted for use as an oil well derrick, my structure is provided with a special form of top structure 35 and gin pole 36 mountedA on said top structure. Said top structure comprises plates 31, welded respectively upon the upper ends of the uppermost legs I, a pair of I-beams 38 resting respectively at opposite sides of the derrick upon the plates 31 at said sides and connecting members 39 connecting the ends of said 1 I-beams. The lower flanges of the I-beams 38 are bolted to the plates 31 by bolts 48. The connecting members 39 are formed with end flanges 4I which are bolted to the intermediate members of the I-beams 3 8 by bolts 42. The gin pole 36 comprises a pair of stanchions 43 and a horizontal bar 44 supported at its ends respectively by the upper ends of said stanchions. Each of said stanchions comprises a base plate 45, a pair of upwardly converging legs 46 welded at their lower ends to said plate, a horizontal sleeve 41 Welded to the upper ends of said legs, and a plurality of vertically spaced horizontal braces 48 welded at their ends to said legs respectively. 'I'he ends of the bar 44 are tted in the sleeves 41 of the stanchions 43. 'Ihe legs 46, sleeves 41 and braces r48 of the stanchions 43, and the bar 44, are of tubular form and may consist of sections of pipe. The base plates of the stanchions 43 rest upon the upper anges of the I-beams 38 respectively and are bolted to said flanges by bolts 49.

In assembling and erecting my structure, the lowermost legs I are rst placed upright with their lower ends resting upon a suitable foundation `50. vGirts 2 are placed between opposite 1egs 7 5 legs to which at the sides of the structure and the ends of said girts connected to said legs by slip joints I6 The remaining legs are assembled, together withV said lowermost legs end-to-end, and each leg is connected to the next leg by a slip joint 4, and as each pair of legs at each'side of the structure are assembled, girts 2 are connected at their ends to said legs by slip joints I6, the pins I1' engaging the slots I8 of said joints and preventing twisting of the structure. As each pair of oppositely disposed legs at each side of the structure are joined to the next lowerpair of legs, a pair of tie rods 3 are 'extended diagonally across each other and said tie rods are connected'at their lower ends by nuts 26, to the brackets 28, at the upper ends of said next lower legs, while the upper ends of said rods are connected to the brackets 29 near therupper ends of said upper pair of legs I, whereby each pair of legs is tied and braced to the next lower pair of legs. The top structure 35 is placed with the lower members of its I-beams 38 resting upon the top plates 31 on the upper ends of the uppermost legs I and said I-beams are secured to said top'plates by the bolts 40. The gin pole 36 is then placed with its base plates 45 resting upon the upper members of the I-beams 38, and said base plates are secured to said I-beam members by the bolts 49.

The structure may be readily taken down by disengaging the bolts 49 and removing the gin pole 36 from the top structure 35; disengaging the bolts 40 and removing said top structure from the top plates 31; disconnecting the tie rods 3 and disconnecting the girts from each pair'of said rods and girts are connected; and disconnecting and removing each pair of legs from the next lower pair of legs.

When used as an oil well derrick, the window 30 is connected to the legs I by means of the slip joints I6, which connect the lower ends of the girt members 32 and the outer ends of the girt members 33 to the lowermost legs, and the slip joints I6 which connect the girt member 3I to the next lower legs.

Referring to Fig. 5 of theA drawings, the girts 2 may consist of three members, an elongated intermediate horizontal member 5I and the depending end members I8, which intermediate members are joined at their ends tothe upper ends of said end members by welded mitered joints 52. The pins I1 and slots I8 of the slip joints I6 are used to prevent twisting of the strucand I8 are oval in cross Ihorizontal girts, slip joints ture when the girt members I8 and sleeve members I1 of said slip joints are cylindrical.

In the modied form of the slip joints I6 for the girts, shown in Fig. 13 the joint members I1 section to prevent twisting of the structure.

In the modified form of the slip joint I6 shown in Fig. 14, the joint members I1 and I8 are formed with engaging

flat sides

52 and 53 to prevent twisting of the structure.
