Be it known that 1, FRANKLIN C. HALL, a citizen of the United States, residing at lil., Albertville, in the county of Marshall and State of Alabama, have invented certain new and useful improvements in fell .Vindlaisses, of which the following is a specilication.- i

This invention appe'rtains to hoisting applia'nces and more particularly to ay novel device for raising well buckets.

The primary object of the present invention is the provision of a well` windlass, which will be easy to operate, and in which thewell bucket can be raised or lowered in a minimum of time with a few turns of an operating` crank.

Another object of the invention is the provision of an improved well windless embody- 20 ing novel means for supporting the hoisting drinn and operating gears, and novel'means for forming the gear casing and for supporting the entire windlass over the well.

A still further object of the invention is to provide a well windlass of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a small cost.

With these and other objects in view, the invention consists in the novell construction, arrangement and format-.ion of parts, as will be hereinafter more specifically described and claimed, and illustrated in the aecompa-nying drawings, in which drawings:

Figure 1 is an end elevation of the improved well windless, l

Figure 2 is afraginentary vertical section taken on the line 2-2 of Figure 1 illustrating thenovel means of mountingl the gears withinthe casing and the means of associat-v ingone end ofthe drum with the said' casing,

Figure 3 is a side elevation-of the improved windlass,

drum ofthe windlass' taken on the line 4.--11 of Figure 3 looking in the directionVV of the arrows,

Figure 5 is a fragmentary longitudinal section taken on the line 5-5 of Figure l illustrating the means of supporting the end of the drinn remote from the gear casing.

Referring to the drawings in detail, wherein similar reference characters designate cor- 5 responding parts throughout the several Figure L1 is a cent-ral sectionthrough theJ views, the letter A generally indicates the improved well windlass7 which includes a drum 10V prei'erably formed of light meta-l possessing the necessary tensile strength. This drum 1() embodies end ydisk shaped 60 plates 11 and .12 which are connected together by spaced hub slats 13 which are arranged in annular formation around the axle center of the drum'. lf preferred the axial center of the end plates 11 and 12 can be increased in thickness as at 14- to insure against breakage at these points. A supporting shaft 15 is provided for the drum and this shaft Vis of a polygonal shape in cross Section one end of the same being provided with a short pintle 16 which can be extended through an opening 17 in the end disk 11. The other end disk 12 is provided with a polygonal shaped opening 18 which conforms to the configuration of the shaft 15 and permits the insertion of the shaft into the said drum. This end of the shaft 16 is a-lso p-ovided with a. cylindrical bearing pintle 1 Arranged at one end of the drum 10 is a gear casing 2O which also forms a support for the drum. This gear casing 2O preferably includes companion sections 21 and 22, which meet at the longitudinal center of the easing. The companion sections 21 and 22 include arcuate end walls 23 and spaced liarl side walls rlhis casing gradually decreases in width toward its lower end, as can be clearly seen by referring to Figure 1 of the' drawings. The lower termina-ls of the companion sections 21 and 22 are provided with companion barrels 25 for the reception of a hinge pin 2G, which hingedly connects the said companion sections together. The casing is formed in this manner to Vpermit ready association of the gears therewith, :as will be hereinafter'more fully described. The upper terminals ofthe companion sections 2-1 and 22 are provided with abutting a-pertured ears for the reception of.V a retaining bolt 28 Awhich holds the sections againstopening movement. The meeting edges of the side walls 24- of the sections 21 and 22 of the gear easing are provided with upper and lower pairs of semi-circular notches 29 and 30 respectively which form bearing openings when the sections are in their closed positions. Anoperating shaft 31 isirotatably positioned in the upper bearings 29 and suitable outwardly extending bearing cups 32 are carried by the sections for the reception of ball bearing races 33. Theouter end of the operating shaft 31 is preferably flattened for the reception of any operating crank 34 to permit the ready turning of the said opera-ting shaft. A relatively large spur gear wheel 35 is positioned in the upper end of the casing and is mounted directly on the shaft 3l, and this shaft is preferably flattened between the side walls of the gear casing for the reception of the said gear. A relatively small spur gear 37 is rotatably mounted in the lower end of the gear casing. and meshes with the relatively large drive gear 35. This gear is mounted upon the bearing pintle 19 of the drum shaft 15 and the bearing'pintle between the side walls of the gear casing` is flattened as at 38 for supporting the said gear 37 so as to insure the rotation of the shaft 15 therefrom. These side Walls n 24 of the sections 21 and 22 around the bearing notches 88 are provided with semi-annular flanges 39 which are adapted to form bea-ring cups for the reception of ball bearing races 40 when the sections are in their closed position. The ball bearing races 40 form effective means for supporting the said bearingpintle 19 of the drum shaft 15. By the construction of the casing, the bearing pintle 19 and the shaft 31, the gears 35 and 87 can be readily placed upon the said shafts and positioned within the gear casing and held against accidental displacement.

The gear casing 2O can be supported in any desired way and as shown, the opposite end walls 23 thereof support lateral extending brackets Lt1 which terminate in base plates L12 which can be bolted or otherwise secured to supporting standards 48 carried by the well.

Any desired gear ratio can be used, such as a ratio four to one and it is to be also noted that the diameter of the drum 1() is considerably greater than the diameter of the spur gear 37 and thus it is obvious that only a few turns of the crank 34 will be necessary to raise the well bucket from the well. Any desired means can be utilized for supporting the opposite end of the drum from the gear casing, and as shown a bearing is employed for receiving the pintle 16 of the drum shaft 15 and a suitable ball hearing race 46 is mounted within the bearing ll5. This bearing't is bolted or otherwise secured to a suitablesupport 47 mounted upon the well.

From the foregoing description, it can be seen that I have provided a novel windlass of exceptionally simple and durable construction, which is so constructed that the parts can be readily removed when necessary or desirable for repair and the like.

Changes in details may be made without departing from the spirit or the scope of this invention, but

What I claim as new is:

1. A well windlass comprising` a. drum, a drum shaft therefor extending beyond the ends of the drum and terminating in bearing pintles, and a bearing for one of said pintles, a gear casing' including a pair of companion sections arranged to abut at the longitudinal center of the casing, means con` necting the companionr sections together, the meeting edges of the sections being provided with mating semi-circular upper and lower pairs of bearing notches forming bearing openings, the lowermost bearing openings receiving the other pintle of the drum shaft, an operating` shaft rotatably mounted in the upper pair of bearing openings, the sections of the casing having semi-annular flanges surrounding the bearing' openings defining bearing cups when the sections are in their closed position, ball bearing races mounted in the cups for supporting the operating shaft and the last mentioned pintle of the drum shaft, the portionA of the operating shaft and the portion of the last mentioned pintle extending into the casing being of a polygonal shape in cross section, a relatively large spur gear mounted upon the polygonal shaped portion of the operating shaft, and a relatively small spur gear meshing with the first mentioned spur gear, mounted upon the polygonal portion of the last mentioned pintle ofthe drum shaft, and an operating crank for the operating shaft.

2. A well windlass comprising a drum including end disks, connecting slats for the disks arranged in annular formation, a cylindrical opening formed in one disk, the other disk having a polygonal shapedI axial opening therein, a drum shaft of polygonal shape slidably fitted in the polygonal` shaped opening' in ther end disk and having` a. bearing pintle formed ou one end thereof fitted within the cylindrical opening in the other end disk, a bearing support for said pintle, the other end of the shaft remote from said end provided with the pintle, being also provided with a pintle, a gear casing rotatablyy receiving the last mentioned pintle, a relatively small spur gear detachably mounted upon said last mentioned pintle for movement therewith disposed within the gear casing, a relatively large spur gear disposed in the gear casing meshing with the relatively small gear, and means for rotating said relatively large gear laterally extending brackets formed on the opposite sides of the gear casing, and attaching plates carried by said brackets.

In testimony whereof I affix my signature.
