DERRICK. 2

Application filed July 28. 1925. :Serial No. 46,666.

tions and formed of a plurality of elements which are interchangeable in the various sectionsfor constructing the derrick of any desired height, I

This invention will be best understood from a consideration of the following detailed description, in view of the accom-' panying drawing forming apart of the specification; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in and lower portions and adjacent the'outer the appended claims.

In the drawings:

Figure 1 is a side view indetail of a form of connecting means for the girders and corner posts. v a

Figure 2 is a vertical section of the device shown in Figure 1.

Figure 3 is a horizontal section of the connecting means shown in Figures 1 and 2 taken along the line 33 of Figure 1.

Figure 4 is a view in perspective of the T-plate.

Figure 5 is a side elevation in detail of another form of the connecting means for the corner posts and girders.

Figure 6 is a plan view of the same.

Referring to Figures 1 to 4 inclusive a pair of corner posts 1 are shown in abutting relation sockets of a key plate 20. Said key plate is provided with a pair of

walls

21 and 22 connected together ata corner of the key plate and projectingabove and below the upper and lower surfaces of said plate and integrally formed with two adjacent edges.

of said plate. The opposite adjacent edges are provided with

keys

23 and 24 which project above and below the surfaces of the plate with the inner wall of the keys behaving their ends located in mg flush with an edge of the plate 20 so '2 that the keys project'beyond said edges of the plate. The key plate and abutting ends, of the post 1 are embraced by a gusset plate 25 having a pair of

side walls

26 and 27 located at right angles to each other. The said side walls are provided with openings' 28 and 28 adapted to receive either of the

keys

23 or 24.

A U-shaped bracket 29 is secured to each face 26 or 27- of the gusset plate25 adjacent their outer edges and are adapted to receive v the ends of a girder 29. 'A stop 30 is secured adjacent the inner edge of each wall of the gusset plate and adapted to receive the inner end in abutting relation of the girders '29. It will also be noted that the U-shaped bracket or guide 29 has its outwardly projecting sides 31 located at an acute angle to the horizontal so'that when the girders 29 are placed in position the girders will be located at an acute an'gle to the"hori-.

zontal; The stops 30 are provided with a Ii 32 adapted to engage over a girder 29 an maintain the same in position. The

side walls

26 and 27 at their 'upper free'edges of the side walls are formed 'elon-' besecured to the side walls inany' approved manner. The upper portion of the connection between the

side plates

26 and 27 of the gusset plate 25 is cut away as shown at to form a slot to receive a bolt 36, the bolt being passed through a diagonally disposed passage in one of the corner posts 1.

Referring to Figures 5 and 6 the key plate shown in the previous figures is likewise employed with the gusset plate 25, the gusset plate being provided with the usual elongated slots 33 and a slot 35 to receive a bolt 36 which passes through the slot and diagonally through a corner post 1. A sheath 40 is secured at its opposite ends to the

side plates

26 and 27 of the gussetv plate 25 and has an angular connecting member as shown at 41' for receiving the ends of the girders, 29. The sheath comprises a topplate 42 and side walls or flanges 43 which space the top plate from the walls of the gusset plate 25' to receive the girders 29. The

keys

23 and 24 are received within openings 28" in the side walls of the gusset plate.

What I claim is:

1. An element of a derrick construction comprising means for securing the abutting ends of corner posts'and girders in locked relationandcoinprising an angle iron having a pair of side walls disposed at right angles to each other, stops secured to the out er faces of the Walls, a bracket secured to each Wall adapted to receive the end of a girder with the end of the girder abutting the stops, and a key plate received between the walls of the angle iron and having sockets at its opposite faces to receive the abutting ends of the corner posts, and complementary means included in the angle iron and key plate for maintaining the relative position of the plate and angle iron.

2. An element of a derrick construction comprising means for securing the abutting ends of corner posts and girders in locked relation and comprising an angle iron having a pair of side Walls disposed at right an gles to each other, stops secured to the outer faces of the walls, a bracket secured to each wall adapted to receive the end of a girder with the end of the girder abutting the stops, and a key plate received between the walls of the angle iron and having sockets at its opposite faces to receive the abutting ends of the corner posts, said key plate being provided with lugs secured to a pair of its adjacent edges and projecting from opposite sides of the plate, the walls of the angle iron being provided with openings to receive the lugs of the key plate.

3. An element of a derrick construction comprising means for securing the abutting ends of: corner posts and girders in locked relation and comprising an angle iron having a pair of side walls disposed at right angles to each other, stops secured to the outer faces of the Walls, a bracket secured to each wall adapted to receive the end of a girder with the end of the girder abutting the stops, a key plate received between the Walls oflthe angle iron and having sockets at its opposite faces to receive the abutting ends of the corner posts, the brackets on the side walls being located above the stops whereby the girders are supported at an angle to the horizontal.

4. An element of a derrick construction con'lprising means for securing the abutting ends of corner posts and girders in locked relation and comprising an angle iron having a pair of side walls disposed at right angles to each other, stops secured to the outer faces of the walls, a bracket secured to each wall adapted to receive the end of a girder with the end of the girder abutting the stops,

and a key plate received between the Walls 5. An element of a derrick construction comprising an angle ironplate having a pair of walls at right angles to each other, said side walls being provided with elongated slots, a key plate interposed between the op posite ends of the angle irons andadapted to receive the abutting ends of corner posts, keys projecting from the adjacent edges of the key plate and adapted to be seated within the slots in the side walls of the angle irons, a sheath provided with pairs of laterally projecting flanges secured to each side Wall of the angle iron and to receive the adjacent ends of a pair of abutting girders.
