Application filed May 12, 1927. Serial No. 190,848.

This invention relates to drum assemblies and more particularly to a drum assembly for use in connection with the draw-works of Well drilling apparatus. V

Changes in conditions in well drilling have brought to light the fact that the ordinary drum structure previously employed in the draw-works of well drilling apparatus is inefiicient and dangerous when employed with the present day deep well drilling apparatus and attempts to modernize this ordinary drum structure and. adapt the same for use with deep well drilling apparatus have so weakened the drum structure that it be comes dangerous. These drum structures, as ordinarily manufactured, are furthermore difficult to apply to the draw-works shaft and when applied, demand an excessive space on the draw-works shaft, due to the fact that the keys which hold the drum in position upon the shaft must be driven from the outer ends of the drums and accordingly keyways must be provided, which extend beyond the outer-end. of the drum hub. This provides a roughened shaft surface, which inhibits compactness, in that at opposite ends of the drum of the draw-works a paratus, there are arranged upon the sha t, elements which have rotation with relation to the shaft, so that these roughened shaft surfaces would tend to destroy the same. Furthermore, it has been found necessary in new drum structures to employ means for watercooling the flanges of the drums, due to the fact that these drums .heat excessively through their operation against the brakes when lowering heavy loads through long distances, as required in present day drilling apparatus. The combination of keyways and bores formed in the shaft for the passa e of water has a tendency to weaken the shaft, so that this shaft must be made of much greater size if a proper safety factor is to be preserved. Accordingly, an im portant object of this invention is to provide a-drum construction, such that the keyway slots for the securing keys may be positioned inwardly of the ends of the drum and accordingly permit theidrum structure to be as compactly arranged as possible for the size drum employed and which will permit of the use of water-cooled flanges upon the drum withoutthe formation of coinciding water passages and keyways, which woul bled.

weaken the shaft structure and necessitate the use of a largershaft.

A ,further object of the'invention is to provide a device of this character, in which the drum structure is such that the. roblem.

of circulating the cooling fluid an assembling the drum upon the shaft is greatly simplified.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of-illustration is shown a preferred embodiment of my invention and wherein Figure 1 is an enlarged fragmentary sectional view through the drum, shaft of a draw-works having a drum applied thereto in accordance with my invention;

Figure 2 is a similar view showing the manner of setting the keys of the drum I structure when positioned upon the shaft;

Figure 3 is a section on the line 3 -3 of Figure 2;

Figure 4 is a section on the line 4'4 of Figure 2.

Referring now more particularly to the drawings, the drum is formed in two sections 10 and 11, each having a hub portion 12 and a brake flange 13, which projects beyond the outer face of the outer end of its hub. These brake flanges provide an annular water circulation space 14. The inner end of the drum section 11 is provided with an extension 15 having a tapered outer face 16, which en ages with a correspondingly 'tap'ered face ormed u on the inner end of the drum section 10, w ich seats against the end of the section 11 proper and combines therewith to provide a continuous smooth drum surface. The inner face of the drum I each-drum section is formed with a pair of keyways 18spaced apart and adapted for the reception of ta ered ke s 19 inserted from the inner end 0 the hu Each hub section is furthermore provided with openings QOQpreferably four in number and uni formly spaced and twoof the openings of' each hub structure align with the keyways of the o posite, hub when the drum is assem-" he extension 15 has an inwardly directed flange 21 having openings 22 corresponding -in number and arrangement to the openings 20 of its hub formed therethrough The shaft 23 is provided with keyways 24, for the reception of the keys 19, the outer ends of which are spaced apart a distance less than the distance between the outer ends of the hubs when the sections of the drum are in assembled relation and the inner ends of which extend inwardly of the inner ends of these hubs. Bores 25- extend inwardly from the ends of the shaft 23 and terminate outwardly of the ends of the keyways. The shaft is provided upon its exterior from a point immediately outwardly of the ends of the keyways with threaded portions 20.

In assembling the drum upon the shaft, the keys are placed in position and the drum sections pressed upon the shaft are properly engaged with these keys. After the drum sections have been properly placed and the tapered extension 15 is fully engaged in the end of the section 10, collars 27 are screwed upon the threaded portions 26, so that they abut the outer ends of the hub 12. These collars are of such width that they do not project beyond the outer faces of the brake flanges 13 a distance greater than is absolutely necessar for clearance and the inner faces'of'these collars are formed with annular ooves 28, which are in communication with the associated bore 25 of the shaft through a radial port 29. The annu-.

' is made between the water spaces by insorting a conduit 34 through aligned

openings

20 and 22 and connecting the same, as at 35, with conduits 36 communicating with the water spaces 14 at points diametrically op osed to the conduits 32.

t will be obvious that by employing a structure of this character, the drum is not only capable of being more conveniently and compactly applied to the shaft 23, but may be much more readily handled, since the weight of these sections'will be considerably less than that of the ordinary drum structure which is ship ed as a unit. The operation of pressing t e sections upon the drum will be much easier than that of applying the ordinary drum, and at the same tlme, a very convenient and efficient method of providnig water circulation is provided without weakening the shaft 23 to the extent that is ordinarily necessary.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.
