ERECTING CRANE AND GIN POLE.

Application filed January 15, 1923. Serial No. 612,817.

T0 all whom 'it may concer/n.'

Be it known that I, FoKKo BRANDT, a citizen of the United States, and resident of Kansas City, county l'of Jackson, State of Missouri, have invented a certain new and useful Improvement in Erecting Cranes and Gin Poles, of which the following is a complete specication. y

This invention relates to erecting cranes and gin poles for derricks, and has for its object to produce -an apparatus adapted for` attachment to the frame of the derrick at different heights as the height of the derrick increases, for the purpose of raising or lowering parts, particularly heavy parts, for incorporation -in the derrick, or for use in conjunction therewith for handling well casing, pumping apparatus and the like.

More specifically, the object is to produce lifting apparatus for enabling parts to be etiiciently raised or lowered within the derrick and thereby minimize the chance of injury to workmen or others, from falling parts or the like, and utilize the derrick structure itself-as a support for liftingand lowering parts without imposing lateral or twisting strains on the structure.

A still further object is to produce apparatus which can be easily and quickly secured in or removed from Operative position at any elevation, and which possesses maximum strength combined with light weight and economical construction.

With these objects in view, the invention consists in certain novel and useful features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood reference -is to be had to the accompanying drawings, in which:-

Figure l is a side elevation of the lower part of a derrick in course of erection and showing a crane in its lowest operative position thereon;

Figure 2 is a side elevation of the top of the derrick and showing the gin pole thereto in operative` position;

Figure 3 is a top plan view of the gin pole with the derrick in horizontal section adjacent the plane of the lower ends of the legs of the gin pole;

Figure 4 is an enlarged vertical section through the adjacent end of one pair of the leg sections of the derrick and the sleeve connecting such sections, the figure also showing the relation between said sleeve and the lower end of a crane;

Figure 5 is a section on theline V--V of Figure 4;

Figure Gis a perspective view of a pilot pin employed at the adjacent ends of superposed leg sections of the derrick;

Figure 7 isa fragmentary side elevation of the gin pole construction;

Figure 8 is a similar view with a part in central verticalsection;

Figure 9 is a vertical section of the sameconstruction taken at right angles to the section of Figure 8; and

Figure 10 is a .detail perspective view of part of the crane and pin pole construction.

ln the said drawings, l indicates the base frame of a derrick or the like, resting on concrete piers 2, the corner posts 3 of the derrick being composed of sections connected together by coupling sleeves 4. The sleeves at corresponding heights,`are connected by horizontal tie bars 5, and'sleeves of adjacent levels with one or more exceptions noted, are connected by crossedbraces 6. At a suitable height, one tier or panel of the derrick, at one side, as shown, has adjacent tie bars 5 connected intermediate their length by spaced uprights 7, to leave a space or passage for the operation lofa walking beam (not shown) if desired, and the framework at opposite sides of saiduprights is .stiened by crossed braces 8. The

special construction of the framework, how

ever, is important in this connection only in Irelation to the sectional construction of the corner posts and in the special type of coupling sleeves for the sections of said posts, as 'l the constructional features mentioned are important with respect to the crane and gin pole. -Reference is also made at this point tothe crown block assemblyf9, at the top of the de rrick, though the particular construction thereof is of no importance as regards this invention, except in `the fact -that it is composed of parts preferably assembled together after individual elevation to operative position and disconnected so that such parts or elements may be in- 4 dividually lowered to the ground.

ends of the post sections the coupling is diametrically enlarged as at 10, (see Figure 4) and from the lower end of such enlargement is split as at 11 to its upper end. At opposite vsides of thesplit are lugs 12 to be brought together to clamp the sleeve upon the upper post section, by a clamping bolt 13. Centrally of the said enlargement, the coupling sleeve is provided at diametrically opposite points with inwardly-projecting segmental lugs14 (see Figure 5) abutted at its under and upper sides by the ends of the underlying and overlying post sections, and at its lower end the coupling sleeve is provided with a perforated lug 15. To strengthen the post section connections but primarily for guarding against relative turning movement of said sections, a pilot pin is provided, composed of an upper portion 16 secured immovably in the upper post section, a reducedflower portion 17 .fitting in the underlying post section and a neck portion 18 from which projects opposite segmental lugs 19 fitting in the spaces between lugs 14 and cooperating with the latter' in carrying the load and preventing relative turning movements of the post sections, the pins also having tongues 2O projecting through the slits 11.to serve as guides in readily'interposing the lugs 19 between the lugs 14 and thereby insure longitudinal alinement of all of the perforated lugs 15 of j lowering rope 26.

the respective corner posts of the derrick to provide for the ready support of a crane or gin pole element, as for the proper support thereof,two of the sleeve-lugs 15 are employed, as will be noted by reference to Figuresl and 2.

For quickly and easily raising or lowering post sections, braces, etc. as the erection or dismantling of the der rick progresses, one or more cranes will be found convenient, and such cranes when coupled in pairs to constitute what is known as a gin pole, serve for raising and lowering material and the vlike within the derrick.

The type of crane employed, comprises a pipe 21 provided with a pair of arms 22 having depending pins 23 for pivotally engaging a pair of lugs 15 of adjacent sleeve couplings, said pipe having an. oppositelyprojecting arm 24 at its' upper end for the support of a sheave 25 and a lifting and As in the erection and dismantling of the derrick, the usefulness of the crane at any 'particularlevel ceases. it is shifted to a higher or lower level and engaged with a diderent pair of lugs 15, this adjustment being repeated until. all parts have been raised or lowered.

TWhen the derrick is completed and it is desired to provide for lifting beams for the crown. block or other heavy parts. a pair of cranes are secured as explained, on diagonally-opposite corner posts, and connected at their upper ends by a bar 27 (seeFigu'res 2 and 3). To make such connection secure and provide a stable and self-adjustable connection at each end of the bar, the arms 2.4 at the top of the cranes, are provided with diametrically slotted concave heads 28, and brackets 29 secured to the bar, have stems 30 extending through the slotted heads 28 and into the cranes, and downwardly-facing convex shoulders 3l engaging said concave heads, the arrangement being such that the bar is firmly supported should any slight inequality' exist in the angular positions of the cranes from any cause. To facilitate the ascent and descent of the derrick, one of the corner posts may be equipped with steps 32, clamped or otherwise firmly secured in place.

From the above description it will be apparent .that I lhave produced a structure embodying the features of advantage set forth in the statement of the objects of the invention and other desirable features, and it is to be understood that the invention is susceptible of modification in various particulars within the principle of construction and mode of eperation involved without departure from the scope of the appended claims. I clai'mz.
