Definitions

  • the invention has particular reference to a device which will engage a watch crystal while it is in place in a watch and remove it therefrom; which will pick up a watch crystal from a supporting surface and hold it in such a manner that its fitment in position in a watch bezel is greatly facilitated.
  • a tool of the kind to which the present invention relates is disclosed in my co-pending application for patent Serial No. 57,521, filed September 21, 1960.
  • FIG. 1 is a vertical sectional view through a tool for removing and fitting crystals, constructed according to the invention
  • FIG. 2 is a view of the under side of the device, with its supporting stand not shown;
  • FIG. 3 is an elevational view of the supporting stand
  • FIG. 4 is a top plan view of the supporting stand
  • FIG. 5 is a view of the central threaded stem, with certain parts of the device mounted on it;
  • FIG. 6 is an elevational view of the .tool
  • FIG. 7 is a top plan view of the same.
  • FIG. 8 is a face view of one of the crystal-engaging fingers
  • FIG. 9 is an edge view of the finger.
  • the casing or housing of the tool is composed of two sections or halves, the upper section being that generally indicated at 1, and it is of cup-shaped formation and includes a top wall 5, a circumferential rim 3 and a skirt 3a.
  • the rim 3 is for hand engagement to rotate the part 1 of the casing and it may be knurled as shown in FIG. 1.
  • the lower section of the casing is generally indicated at 2 and the same is also of cup-shape and it includes a bottom wall 4.
  • Both the upper and lower cup-shaped parts of the casing may be, like other parts of the device, composed of plastic material if desired, or they may be made of metal.
  • the lower cup 2 is of such internal diameter that the skirt 3a of the upper cup 1 fits within it so that the upper cap may be rotated as well as moved axially within the lower cup, and in telescopic fashion.
  • a boss 26 Centrally provided in the upper wall 5 of the upper cup 1 is a boss 26 providing a recess or well 6 which accommodates a hexagonal or other non-round nut 7, the well being complementary in shape to the exterior of the nut,
  • Saidstem 9 is provided at one end, or at the lower end of the tool, with a hexagonal o-r non-round head it fitted within the bottom wall 4 of the lower cup 2, thereby maintaining the stem non-rotatively with respect to said lower cup.
  • a sleeve 11 Mounted on the stem 9 adjacent to the head end of the same, is a sleeve 11, provided with an annular groove 12 (FIG. 1) that is engaged by the crystal-gripping finger's 13.
  • These fingers constitute crystal-engaging jaws and each of them is in the form of a flat, tapered metal plate having an enlarged head 15 at its upper end terminating in a rounded extremity 14, forming a notch 16.
  • the head 16 is formed with a nose portion 17 so shaped as to engage with the groove 12 in the sleeve 11 as clearly shown in FIG. 1.
  • This engagcment permits a rocking or pivotal movement of each of the fingers.
  • the upper edge of the nose portion 17 is curved as shown at 18, which curved portion extends under the concave side of a cupped washer 19 fitted around the threaded stem 9 and confined between the top of the sleeve 11 and a pair of nuts shown respectively at 2i) and 21 threaded on the stem 9.
  • a conical coil spring 22 is seated on the bottom wall of the lower cup 2 and is seated at the top in the notches 16 of the fingers 13. This spring biases the fingers to open or spread position.
  • the adjusting head 23 for the jaws is in the fo-rmof a frustro-conical follower having a central aperture 24 fitting around the stem 9 and freely movable up and down thereon.
  • a washer 25 is interposed between the top of the adjusting head 23 and the boss 26.
  • the adjusting head 23 is shown in a raised or elevated position away from the fingers 13, and the one finger therein shown is in its innermost position. The parts are shown in these positions primarily for illustration, since normally the flange 28 on the head '23 is in constant contact against the tops of the fingers.
  • FIG. 2 which shows the bottom of the lower cup
  • the bottom wall 4 of that cup is formed with a plurality of radial slots 27 through which the fingers 13 are extended to project below the bottom wall 4.
  • These slots are of such length as to permit the required pivotal movement of the fingers to thereby enable the fingers to accommodate various sizes of watch crystals between them.
  • twelve of these slots and twelve fingers are shown, but this number may be increased or decreased if desired, each of the slots accommodating one of the fingers as shown. In FIG. 1, only one of the fingers is shown for clarity in illustration.
  • the adjusting head 23 will be' moved up or down, so that its peripheral flange 28 will engage against the tops of the fingers 13 to move the. fingers pivotally toward one another or to permit them to separate under the biasing pressure of the spring 22.
  • the stem 9 is provided with an axial passage 29 and a rod 30 is freely slidable therethrough, the rod being provided at its upper end with a knob 31 forming a finger-piece, and at its lower end below the wall 4, with a conical head 32.
  • a central aperture 38 is provided in the base.
  • each of the posts is provided with a notch, forming a seat or shoulder on which .the tool is rested as shown in FIG. 4.
  • FIG. 1 only one of the posts is shown, but it.will be understood that the tool rests onall three of the posts when in its supported position on the stand.
  • the curvature ofthe upper. or concave surface of the concavity is suchthat it conforms to the arc of swing of the fingers 13.
  • tions or steps 40 and these steps are arranged in groups of .threeof differentheigh-ts.
  • thelower ends of the fingers Whenv the tool is rested on the seats 36 of the stand, and with the tool supported on threeof the disks of the same predetermined height, thelower ends of the fingers will be located at a given distance from the upper surfaceof the concavity-34 so that the edged the. crystal then resting on the surafce' of theconcavity, will be engaged by the fingers at such given. distance from the lower surface of the crystal. Thisallows a sufiicientamount of the edge of the crystal tobe exposed below the. lower ends of the fingers 13 to permit such portion'of the edge to be engagedinthe groove in the bezel of the watch when fitting the crys-. tal in place therein. 1
  • -.Sincethe crystals vary in height, and the lower-ends.
  • the projections or steps 40 are arrangedin groups of .three of diiferent height. For example, three of these. projections are arrangedfor a clearance of .010; three arranged fora clearance of .020; three for a clearance of .030 and three arranged for a clearance of .040, with. theseclearancesmarked on the projections. Additional projections of other heights can also be provided as required.

  • the crystal to be'picked up preparatory to beinginserted in the bezel of a watch is centrally positioned in the concavity 34 of the stand with. its convex facez disposed uppermost.
  • the tool is placed on the stand with the steps or projections'40 of theselected heightseated upon the seats or shoulders 360i the posts 35.- By depression of the rod. 30, the crystal will be heldvdow'n on the concavity ofthe. stand, while the upper cup 1 is rotated by finger engagement with its rim 3. This will cause.
