This invention pertains to sand reels, such as are used in connection with well drilling rigs to operate the sand line.
One of the objects of this invention is to provide an improved construction for the driving mechanism for a sand reel which Shall render the same more economical to manufacture and more eiicient and reliable in service.
Further objects will appear from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a plan view of part of a drilling rig showing` sand reel mechanism embodying this invention;
Figure 2 is a side view of Figure 1;
Figure 3 is an enlarged detail sectional view of the band wheel clutch drum and its operating mechanism;
Figure 4 is a top view of part of Figure 3, showing the band tightening mechanism;
Figure 5 is a side view of the sand reel clutch ldrum and brake mechanism;
Figure 6 is a detail of the operating connections of Figure 5, shown in plan view;
Figure 7 is a detail of the brake tightening device of Figure 5, shown in side view;
Figure 8 is a perspective view of the bell crank usedfor tightening the clutch bands;
Figure 9 is a top view, enlarged, of the driving sprocket andits mounting;
Figure 10 is a front view of the same; and
Figure 11 is a perspective detail of the bell crank mechanism.
Referring to the drawings, 1 designates the main sill, and 2 and 3 the head and tail sills of a standard drilling rig. 4 designates the band wheel shaft mounted in bearings 5 and 6 inthe usual manner and carrying a band wheel 7 Mounted on cross sills 8 by means of brackets 9 in which it is journaled is the sand wheel shaft 10, carrying the sand reel 11.
Bolted to the band wheel 7 by means of bolts 12 is a clutch drum having a web 13 and a rim 14. The web `13 fits over and encloses the regular hub flange 130 of the band wheel. Formed on the web 13 is a flange 15 having formed in its Outer periphery an annular recessl, adapted to provide a. bearing for Serial No. 132,363.
the hub 17 of a driving sprocket 18. The clutch drum is preferably split across the diameter so that it mayv be assembled around the shaft 4, the two halves being bolted together after assembly by means of bolts 19, as shown in Figure 3. The sprocket 13 is also spiit so that it may be assembled upon the ange and seated in the annular' recess 16 so as to be movable therein.
The mechanism described in the preceding paragraph provides a releasable connection for driving the s rocket 18. lVith the parts in the itions sliown in Figures 3 and 4, the clutchiasnd 24 is loose on the rim 14, and the drum may rotate with the band wheel 7 without driving the sprocket 18. Under these conditions the sprocket 18 remains stationary, rotating on its bearing 16 on the drum hub. When it is desired to start the sprocket 18, the element 39 is pulled downwardly shown in Figure 4, thereby rocking the s raft 36 and swinging the arm 35 to the left. This arm is pivoted by pins 43 to the collar 34 so that its movement will move said collar to the left, Figures 3 and 4, thereby rocking the lever 30 on its pivot 31 so as to pull the rod 29 outwardly or to the right, Figures 3 and 4. This action swings the bell crank 27 about its pivot 26, so as to draw up the bolt 42 to tightn en the clutch band 24. This band, then, is thus tightened upon the rim 14 so as to grip the same, thereby causing the sprocket 18 to rotate with the drum and the band wheel 7.
The sprocket 18 is connected by a chain 44 with a corresponding sprocket 45 on a sleeve 46 loosely mounted on the sand reel shaft 10. The sleeve 46 carries a disc 47 which lies closely adjacent the outer rim of the clutch drum 48 on the sand reel shaft 10. The drum 48 usually is provided with two drum surfaces, the outer one of which is adapted to carry a clutch band 49, while the inner surface carries a brake band 50. This drum is xed to the sand reel shaft 10. The disc 47 is provided with a lug 51, similar to the lug 32 on the sprocket 18, and has pivoted thereto a lever 52, similar to the lever 30. The disc 47 is also provided with a lug 20, similar to that described for the sprocket 18, and having Similar connections with the clutch band 49 for tightening the same through the action of a thrust rod 29, as described for the tightening of the clutch band 24.
The lower forked end of the lever 52 is connected at its ends with a pair of thrust rods 53. These rods pass through perforations in the sprocket 45 and are carried by a sliding collar 54, similar to the collar 34, and whose groove is engaged by pins 55 carried by the forked ends of an arm 56 pivoted at 57 on a bracket 58 supported on the bearing bracket- 9. The arm 56 is pivoted at its lower end to a bell crank 59 pivoted on one of the sills 8 and which has connected thereto a pull rod 60 running to a convenient` place for operation so that the operator may Work this rod in order to tighten or release the clutch band 49 in a manner similar to that described for the clutch band 24. The pull rod 60 may also be connected to a lever 61 pivoted at 62 and connected at its other end to a rod 63 connected to operate a toggle 64 working a bell crank 65 pivoted to a bracket 66 and connected to operate the pull rod 67 for tightening the brake band 50. The mechanism just described in connection with the sand reel clutch drum 48 provides a releasable connection for driving the sand reel and for stopping the same at will. Vs'hen the operator pulls on the rod 60, the bell crank 59 is swung to the right, Figure 6, thereby operating the rods 525 so as to swing the lever 52 on l its pivot 51 to force the rod 29 to the right, Figure 5, thereby releasing the clutch band 49. At the same time, through the agency of the lever 61 and the connections 63 to 67 inclusive, the brake 50 is tightened so as to hold the sand reel against rotation. By pushing on the rod 60, the parts are moved in the opposite direction and the clutch band 49 is tightened while, the brake 50 is released. lVhen the clutch band 49 tightened, the same grips the drum 48 so as to cause it to rotate with the disc 47.
It will be seen, therefore, that this invention provides a simple construction for a sand reel drive of this type. ln putting the device into service, the operator first starts the sprocket 18 by operatingl the rod 39 so as to tighten the clutch band 24 in order to set said sprocket into motion. Thereafter he may start and stop the sand reel at will by operating the rod 60 as above described.
This invention provides a simple and rugged construction for this mechanism. The clutch drum is provided with an annular recessed bearing which has an integral flange on its out-side end, and the sprocket hub is seated in this bearing for rotation therein. The sprocket is split so that it may be mounted in its bearing so that the outer flange of the bearing may be made integral therewith, thereby increasing its strength and cheapening its construction. The improved form of lug 20 and the construction of the bell crank 27 are such as to simplify the means for tightening and releasing the clutch band and render the same adjustable so as to vary the tension thereof when required.
It is obvious that various changes may be made in the details of construction without departing from the spirit of this invention; it is to be understood, therefore, that this invention is not limited to the specific details shown and described.
Having thus described the invention what is claimed is:
1. A well drilling rig including a drive shaft mounted Iin bearings and a band wheel on said shaft and between the bearings, and sand reel driving mechanism constructed and arranged for assembly over the drive shaft and against the band wheel and comprising: a split clutch drum having a bearing and constructed for mounting over the drive shaft and against the band wheel, a split driven element constructed for mounting on said bearing and having a band for engagin said drum, and means for moving said ban into and out of cooperation with said drum.
2.

3. A well drilling ring including a drive shaft mounted in bearings and a band wheel on said shaft and between the bearings, and sand reel driving mechanism constructed and arranged for assembly over the drive shaft and against the band wheel and comprising: a split clutch drum having a bearing and constructed for mounting over the drive.
