,-.This invention. relates` to a tool for. use in handling. small parts ofdelicate machinery..
Inv general the device comprises. two ngers which` arepivotally connected. to a. body member and which are adapted to swing towardv and away from each other for grasping or releasing apart to behandled. A rod., slidable in the body member, with links connecting said rod. and the i-nger members, serves to effect a relative movement of. said fingers. In the form of the invention. hereinafter described in detail,. the fingersare urged apart by pressing downwardl'y onthe rodA and are automatically forced together by the aid. ofa spring device.. Recesses may loeV provided in the lowermo'st ends of the iingers for. accommodating the part to be handled and. the shape of said ends and saidl recesses maybe varied to accommodate any particular part, without departing from thel spirit of the invention. .I
Muchdi-iiiculty is encounteredin removing, particularly the second-hand of a lwatch without breakingthe same. It is also` di'flicult to. subsequently hold and ream ther opening in' the hub portion thereof. Applicant]` has therefore chosen to form the ends of the finger members andf the recesses therein to accommodatethe second-hand' of a watch.
An object of the invention isthe provision of` a tool which serves as a vise in removing handling or iitting watch-hands or other delicate parts.
Another object is the provisionV of av tool for removing, handling or fitting delicate' parts, which includes two pivotarlly supported grasping fingers adapted for movementtoward and away from each other for grasping o'r releasing a part and spring actuating means for normally urging saicl fingers together.,v i
AA further object of the' invention is the provision of a tool for removing, handling or fitting Ithe second-hand of a watch, which includes two pivotally supported grasping ngers adapted' for relative swinging movement and having means formed at their free ends which are cooperative to receive the hub of a secondehand and permit the sleeve portionthereof to project outwardly between said fingers.
nAnother object is to provide a device ofthe character above referred to, wherein the grasping `fingers are provided withv elongated grooves which are cooperative when the ngers are together-to dene an opening to` accommodate a drill or'the like when it is desired to ream the hub opening in a second-handY or other delicate part.
A still further object is to. provide a tool of the character referred to, which is compact and has a minimum number of workingY parts, substantially all of. which are hidden from view.
This invention possesses many other advantages anch has'otherobjects which may be made more easily apparentfromr a consideration of one embodimentV thereof. For. this purpose one form is shownin the accompanying drawingA and forming part of thepresent specification. I shall invention; but it is to be understood that thisdescription is not to be taken. in a limiting sense, since the scope ofthe invention is best defined in the appended. claims.
Referring to ,thel drawing Y Figure 1 is an elevation, partly in section, of a tool constructedin accordance with theA pres.- ent invention; n V
Figure 2A` is a vertical sectional view through thetool. f', j v
kFigure 3' isan end. elevation taken as indicated, byline 3'-3 ofFigure. 1 and' showing the grasp'- ing ngers in anfopen position.
Figure 4 is a transverse sectional view taken as indicated Vby lined- #1- of Figure 2 and Y Figure 5 isan enlarged: fragmentary sectional View of the grasping ends` of the finger members and showing 'a 'second-hander" a watch heldj therelc'iet'ween` j Referring more' in particular tothe' accom-` panyingkzlrawing,l applibants invention includes a body portion' 10, the outer surface of which may be formedsuch as tof-make the tool most easily handled when" kworking with: delicateV parts. Two depend/ing iingers-".'ll 'andv `12fvare pivotally connected' at the lowerendof the bodyl member 10 as by the aid' of pivotpins 153fandll'.'l Said ngers are 'adapted to be moved;Y towardvand away from each other inV a4 manner more fully hereinafter set forth, for the purposeof grasp-v ing orj releasing a part to be handled-1.
' `In orderl to' make a more compact and' neater appearing tool, applicant prefers in the present instance to enclose the'pivotediends-of thefinger members 1I and' '12; H'e accomplishes this by forming a'holl'ow shell-portion 15, (shown in Fig'- ures 2` andi 4) at the lower' end of the` body member 10 and into which thesomewhat reduced end' port'ions 16"and' 17of'the fingers enter. Thepi'vot pins 13 and 14 pass through the reduced'portions of the iingers andare supported in the 'walls' of the hollow' shell' portion 15,. as shownclearest inl Figuret. Although not shown, applicant prefers to provide a relatively loose' fit between the pivot pins 13 and 14 and the openings inathe ref' duced portions of the fingers. This is for: the purpose of further enhancing jay free movement of said ngers.
Where exceptionally small and delicate'parts are involved,.it is desirous to usefa verysmall tool. Applicant is able to construct such a tool in ac-v cordance; with his invention by arranging the parts in the manner.' hereinafter described.' A
tubular guide member 1:8 yis .secured in the bo'cly member 10 and projects somewhat below the lower end thereof. The finger members 1l and 12 are provided with semi-circular grooves 19 and 20 which are cooperative when the fingers are closed to define an opening for receiving `the lower end of vsaid tube 18. In other words, when the fingers are together, they completely surround said tube as shown in Figure 4. The reduced portions 16 and 17 of thefinger members and also the grooves, are curved as at 21 and 22 to permit the fingers to swing'cn the pivots 13 and 14.
The finger actuating means consists of a rod 23 slidably supported in the guide sleeve 18.` It proi jects below the bottom of said sleeve and carries on its lowermost end an enlarged portion 24. Links 25 and 26Hserve to connect said enlarged portion with the finger members 11 and 12.y One end of said link members enters slots in the enlarged portion 24 -as shown in Figure 3 and is pivotally held therein by a pin 27. The other end. of said links 25 and 26 enter recesses 28 and 29 in the fingers` 11 and l2 respectively and are pivotally held therein by the aid of .pivot pins' 30 and 31.
The rod 23 may be urged downwardly tol spread the fingers apart, as by the aid of a button 32 at its upper end. Said button has an extended portion 33 which enters a spring receiving chamber 34 in the upper end of the body member 10 and is screw threaded onto said rod. A coiled spring 35 between ashoulder 35a on said extended portion 33 and a shoulder 36 at the bottom of said chamber, serves to urge the rod upwardly for normally holding the fingers together.
As heretofore stated, the shape of the free ends of the finger members and also the recesses formed therein, may be varied without departing from the spirit of the invention.
In the present instance the grasping ends of said fingers are designed to accommodate a second-hand of a watch as clearly Vshown in Figure 5. Suitable recesses 36 and 37 are cooperative when the fingers are together for receiving the hub portion 38 of the second-hand, while the usual sleeve 39 is permitted to extend downwardly through an opening 40 defined by the two fingers. In the event that it is desired tol enlarge the-opening 41 of the sleeve 39, or remove somethingtherefrom, applicant has provided semicircular grooves 42 and 43 in the finger members, which are cooperative when said` members are together to form an opening into which a drill or other tool may enter.
Fromthe foregoing description, the actuation of the tool should be clear. When usedto remove the second-hand of a watch,the fingers may be moved apart by pressing` the button 32 as shown in Figure 1.` After placing the fingers on the watch dial and on either side of the second-hand, the button may be released, whereby the spring urges the fingers together and the somewhat sharpened portions 44 of the finger ends serve to pry the second hand loose and urge it into the Y receiving'apertures vwhere it is held as between the jaws of a vise.
I claim:
