SAFETY-DRIVE FOR DBILLING-MACHINE DRUMS.
Leis-,6%.
To all whom it may concern:
Be it known that We, ABIA J. SHARE. and
JOHN O. FOSTER, citizens of the United States, and Vresidents of Harrisonville, in the county of Cass and State of Missouri, have invented a new and Improved Safety Drive for Drilling-Machine Drums, of Whichthe following is a full. clear, and exact description.
In operating drills ofthe type generally known as dropping. drills, the ro e or cable ttacned to the drill and vwin ing on a rum is controlled by a speeding lever,
whereby the cable is alternately slackened lieve the drive devices the said patent, the disposition of Vthe and tautened to raise and lower the drill. In the practicalloperation of such drills the drive devices for actuating the drum are `subject to severe'stra'in exerted on the cable and acting on the `drive through the inedium of the drum. Ina patent granted to us December 2, 1913, No. 1,080,334, safety drive means isprovided involving the use of compression springs interposed between the drive and the winding drum of the drill-v ing machine to cushion the shocks and reoii strains. In
springs is such as to take care of compression, and an important object of the present invention is to provide an arrangement of springs positively fastened at the ends to the drive and driven elements thereby causing the springs'to function for both compression and extension.
The invention also has for an object to provide a more direct application ci? the springs to the drum.
The invention Will be particularly exO plained in the speciic description following.
vided on supporting standards 5,' or the like.
In the bearings is mounted to turn a wind ing shaft 6, Which may be driven 1n any suitablemanner. In the present example l Specification of Letters Patent.
Patented Jan. 23, 1917.
Application fu april 29, 191e. serial No. 94,374.
we have shown a gear wheel 7 on the shaft and indicated in dotted lines a -pinion 7 meshing therewith and mounted on a shaft 7" to be driven from any convenient source of power (not shown).
The drum 8 in the present instance, is loose on the shaft 6 and receives the usual drilling rope or cable 9 which is given a suitable number of turns about the drum, and in practice, connects with the drill, running over guides and subject to the usual speeding lever (not shown), to alternately tighten and release the drill and then permit the same to drop. The power disk 10 is nia-de fast on the winding shaft 6 by a adjacent to one head 11 of the drum 8, said head 11 ,constituting the driven. member. interposed between the drive element 10 and the driven element 11 are the cushioning' springs 17 which We secure positive at `their' ends, respectively, to the said drive 14. The respective lugs, 13, 15, overlap and constitute seats for the springs 17, the ends of which are received on the respective pins 1li 16.
lach stud or pin 14, 16 has a threaded shank 18 extending through holes in the lugs 13, 15 and provided with nuts 19 to secure the same in position. Each pin 14, 16 is notched at its base at a side thereof, as al 20, best seen in Fig. 6. In the driven disk l1 transverse recesses or holes 20 are formed adjacent to the lugs 13 and similar recesses or depressions 21 are formed to the opposed. face of the drive disk 10 adjacent to the lugs 15. The springs 17, at the ends thereof, are. given abend to lie in the respective recesses 20, 21. Thus, the notched formation of the pins, 14, 16, and the engagement of the springs in the recesses of the drive and driven disks constitute one means for positively securing the ends of the springs to said disks, and an important result' is obtained in that we are enabled to give the desired end springV to the cable for the successful operation of the well drill. The positive fastening of the springs at both key or the like, and said disk is positioned ends causes. the same to act under both conipression ;rd extension and to take up the rebound of the drill instantaneously, thus enabling the drill to make a greater number of strokes per minute than is possible with springs simply abutting at their ends against the lugs of the respective disks. To strengthen the lugs, 13, l5, brace ribs 13, 15a, are produced at the backs of the lugs at the junction of the same with the respective disks. Also, it will be observed from Figs. 2 and 3, that the lugs are disposed in planes at an angle to radial lines to dispose the springs in the proper positions about the disks. In the present instance the driven disk 11 is shown as secured to the drum ilange by bolts 12 which pass through holt holes 11 in said disk.
Having thus described our invention, We claim as new and desire to secure by Letters Patent:
l. In a cushioned driving mechanism, a drive and a driven clement, presenting opposed lateral faces formed with transverse posite lateral faces formed with transverse recesses, springs interposed bet-Ween said elements, studs having threaded Shanks, the said elements having lugs through which the said shanks extend, and nuts rigidly Y securing the studs to said lugs, the studs furthermore having lateral notches at the bases thereof in which portions of each spring, ne r the ends thereo, are received, the extrem'ties of each spring extending :trom the said notches into said, recesses.
