Referring now in detail to the drawing, I0 designates an instrument embodying the invention. The same comprises a casing I I having a bottom wall I2, Side walls I3 and tubular end portions vIl and I5. The casing V I I is open at the top and is formed with a central substantially cylindrical chamber I6. -The casing tapers from thesides thereof towards the ends as shown in Figs. 1 and 2 of the drawing.v The end portion I4 thereof is formed with an axial through openingvls com.- municating with chamber I6 and extending .to one end of the casing. Part of the through opening I8 is internally screw threaded as at I9. The end portion I5 of the casing is formed with an axial bore 20. Said casing has a -iiat top surface 2i as shown in Fig. 3 of the drawing, The axial bore 20 communicates with chamber I6. f
Said chamber has a flat bottom wall 22 and an inner cylindrical surface 24, The side walls I3 are formed at their outer surfaces with aligned, circularvrecesses 25. At the center of each recess is a threadedopening 26. The bottom wall I2 is formed in surface 22 thereof with a central threaded opening 28 for the purpose hereinafter appearing. 1
Chamber I6 may be closed by a cover 36 lying on surface 2l. The-cover 30 may beattached to the casing by means of a set. screw 32 passing through an opening therein and screwed into a threaded opening 33 in portion I4 of the casing.
Screwed within the threaded opening I9 is an inner externally threaded sleeve 35. The sleeve 35 is formed with an axial through bore 36. It extends beyond the casing as at 31. .Attached to member 35 is an outer sleeve 40 coaxial with sleeve 35. Sleeve 40 has an end portion 4I fitted onto portion 31 of said member 35. Adjacent portion 4I is an internal collar 42 contacting the outer end of member 35. Said sleeve 46 is also formed at its outer end with an opening 44 for thepurpose hereinafter appearing.
Extending through opening 36 in member 35 is an axial shaft 45. The shaft 45 extends to both sides of member 35. Attached to the inner end 46 of shaft 45 is a beveled gear 41 abutting the inner side of member 35 and projecting into the cylindrical `chamber I6. Gear 41 may be pinned to the 'shaft or otherwise attached thereto. Pinned to shaft r45 and abutting the outer end of member 35 is a collar 49. Attached to the outer end of shaft 45 is an axial sleeve 59 located within the outer sleeve 40 and terminating short of the outer end of said inner sleeve. Said axial sleeve 50 is forrried with a longitudinal slot 5| for the purpose hereinafter appearing.
The outer sleeve 40 is attached to portion 31 of member 35 by means of a set screw 40aor in any other suitable manner.
Attached to the bottom wall i2 of the easing is a screw 55. Screw 55 is formed with a shank 55 screwed within the threaded opening 28. It has a shoulder 51 contaetih'g the upper surface 22 of bottom wall [2i of the casing. It is also formed with an enlarged head 58.
Rotatably` mounted on screw 55 is a beveled gea-r S meshing with the beveled gear 41. Gear 60 is formed 'with an aiial opening 5| to receive shoulder 51 "and head 58 of screw 55. VThe bottom surfac'eof gear 50 rests on the bottom walls 22. Itis heid on the Abc'ittom surface '22 by the Yscrew 55 while permitting the gear to rotate. Attached to the top of gear 6U is a central bridge or hub 64 overlying the head of the screw '55. Said hub S4 is formed with Van onset threaded opening '5. Screwed into 'said threaded opening is a pivot pin 66. Connected to 'said pivot 'pin 'is a link 61. l
Mounted for recprocation within the axial opening 2t of the easing is 'arod 1Q. Rod 10 is formed' with a slot 1| at one end. Fixed to the 'rod and traversing 'said 'slot is a pivot pin 12. The link 61`is pivoted at Vits opposite end to the 'pivot pin 12. It will now be understood that as shaft 45 is rotated, gear 41 willturn gear 260, VVtifh'ich 'turn will reciprocate 'member 10.
Will squeeze together the'slitted portions 15 to fgrip the shankV 81 'o'f aniinstrument inserted `into 'the l`opei`1`i'1"1g 14. v'/Vhen member 82 is rotated in Van opposite direction, it lwill *loosen slitted 'portions 15 t0 pe'lfni't the shank '0f the tO'Ol to be withdrawn from 'the chuck.
v The instrument |0 lmay be operated by'means `fof "a usual 'flexible'sha'ftfone 'end of which is "shown 'at 90. Thieiiexibleshaft E90may be `provided kat `'one end with a connector lhead 9| 'formed with an annular groove 92 'of curved Ihe ball "95 projects into groove 92. -It also 'projects into 'opening '94. "The opening 44 has diameter 'greater jthal the diameter *O'f lball 95. The openin'g`i94, however, is smaller.
the head 9| is slipped into the sleeve, the ball 95 will open up the split sleeve 93 and permit said head to move past the ball, which permits the ball 95 to snap into the groove 92. The head 9| is attached to the easing Sla, for the rotary fiexible shaft 95. The head 9| is formed with an axial through opening 96a. Attached to the flexible shaft 96 is a rod 91 which passes through the axial opening 96a. The rod 96 may enter the sleeve 50 which is nxed to the gear shaft 45. On rod 91 is a rib or key 98 which enters the slot 5|. It will now be understood that rotation of the flexible shaft 96 will cause rotation of shaft 45 for operating the mechanism.
The instrument may be attached to a usual drill press |00 for operation thereby. In such event, the sleeve 40 is removed by unscrewing the vset screw 48. The usual chuck of the drill press may then be engaged with the projecting end of shaft 45 as shown in Fig. 5 of the drawing. The casing may be held against rotation by vmeans of a pair of arms |0| which may be attached as at |02 to the frame |03 of the drill press. The arms |0| may be attached to the sides of the casing Said arms may be provided with bosses |04 which enter the recesses 25. The said arms may be formed with through openings |06 registering with the opening 26 to receive screws |01 for attaching said arms to the casing. The tool 81 is attached to the instrument and is reciprocated vertically. When the drill is operating the instrument may be lowered Aor raised and Aadjusted in position. To this end the arms |0| may be formed with slots |0|a to .receive the attaching screws `|02 which pass through the slots. The provisions of the slots permits adjustment of the arms |0| and .instrument |.0.
Some jewelers have flexiblerotary shafts which are provided with a taperedA chuck Yat one end. To attach the instrument |.0 to such a chuck, the :sleeve 40 isremoved. Also sleeve 35.is unscrewed together with shaft 45, collar 49, and gear 41. As shown in Fig. 6, there is then 4screwed into the threaded opening I9 a sleeve 31a similar to sleeve 35. Extending through the screw 31a is a shaft ||0 to one end of which is attached a gear 41 similar .to the gear 41 of Fig. V3. Also attached to shaft ||0 is a collar 49 ysimilar Ato the collar 49 in Fig. 3. The shaft ||0, however, preferably extends rearwardly to greater length than shaft 45.
Mounted on the rear end of screw 31 is a sleeve |2. The sleeve ||2 may be attached 'to screw 131 by means Vof an attaching screw 40a. Sleeve |,2 has a tapered internal opening A| |3 to receive the usual tapered chuck on a ,flexible shaft. 'The tapered chuck may enter the sleeve I|2 and Will -grip the Vrear .end ofshaft |0 to rotate thelatter.
If desired, the sleeve ||f2 may be entirely removed so that larger chucks maybe iused as grip shaft I0.

Surrounding portion 200 is a coil Compression spring 20'2 interposed between shoulder 20| and an internal shoulder 203 formed between bores |11 and |18.
Any suitable means may be provided to rotate member |85. As member |85 rotates, the
The same comprises aY 6.. cammed edge` |88 will move member-19t tothe right. Thespring 202'wi1lmovemember |9| to the left. Thus' as member 85 rotates, member |9| will be reciprocated.A Member |9| maybe provided at its outer end with a chuck to grip the shank |82 of a tool similar to the structure shown-in Fig. 8. :l 1 y y Y IIf desired, the-instrument may be -attachedto a usual jewelers lathe. In suchevent-the member 85 iszreplaced by amember 20, having a shaft portion |200(r .as shown in Fig. 7. of the drawing.; Attached to theshaft |20a is a collar |2|'.1The collarv |'2| maybe pinned to shaft l|20 and is tapered. sofas to cooperate with the chuck of a jewelers lathe. The shaft |20 is provided with. a` usual `keygroove |23 withan annular groove |24 adjacent thereto and with a rear externally screw threaded end portion |25. With such construction, the instrument may-be lattached to a jewelers lathe. The jewelerslathe may, furthermore be provided with arms |26 having bosses|21 received in recesses |21 in theside walls-of the .instrument casing. Said bossesare provided with central through openings |281; to receive screws 28 screwed within threaded openingsA |26a of saidcasing, at the bottom ofthe recesses for; attaching said arms to the casing. `'The arms |26 may be attached to any f'lxedsupport to prevent the casing vfroml rotating as the zmember|20 -is rotated for operating -the instrument j -g ,l f It v'will beunderstood that shafts 45 or ||0 I ,nay be replaced by shafts such as shaft |20a adapted to be=received in'a-jewelers chuck, if desired. l
It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that al1 matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
