, 14 Claims.

This invention relates to olivaging machines and more particularly to machines for the rounding of corners of the recesses or passages in bearing jewels, although not so limited.

One object of the invention is a semi-automatic machine whereby the relative movement of the several parts is automatically effected whil the operations on the passages in the bearing jewels is controlled manually.

another object of the invention is an olivag ing machine of the character described which is' readily manipulatable to eifect the purpose at hand.

Yet another object of the invention is the provision of an olivaging machine whereby a plurality o'f jewels maybe worked upon at one and the same time.

' A further object of the invention is improved means for positioning the jewels to be worked upon.

Yet another object of the invention is means to retain the jewels in position while at the same time capable of simultaneous release for any acce'ss to the jewels.

Still another object of the invention is to ro tate the jewels while they are being worked upon.

It is also sought by this invention to provide an olivaging machine which is practical from the standpoint of simplicity of construction and ease and convenience in manipulation.

These and other objects of the invention and the means for their attainment will be more apparent from the following detailed description taken in connection with the accompanying drawings illustrating one embodiment by which the invention may be realized and in which:

Figure l is a plan view-of the machine of this invention;

Figure 2 is a view partly in elevation and partly in section taken in the plane indicated by the line 2--2 of Figure 1 and looking in the direction of,thearrows-;

Figure 3 is a sectional view taken at right angles to the section illustrated in Figure 2 on the line 3-3 of Figure 1;

, Figure 4 is a fragmentary view on an enlarged scale showing jewels retained in slots by means of positioning or retaining fingers;

, Figure 5 is a planview taken in the plane indicated by the line 5-5 of Figure 4 and looking'in the direction of the arrows; and

Figure 6 is a view similar to Figure 5 but showing the displacement of the jewels in the performance-of work thereon.

Referring first to Figures 1 and 2, the base of the machine is indicated at II]. This base may be circular in plan and adapted to stand upon a table or other support. It is formed axially with a recess l2 in its lowermost portion which opens into a fru'sto-conical bearing surface M adapted to receive a -frusto-conical annulus I6 by which a table I8 is mounted for rotation on the base Ill. The table is secured to the annu-' lus l-G, as by pins 20 and ascrew 22.

The table l8 is illustrated a rectangular in cross-section and conveniently of a length greator than the diameter of the base. It is formed with a dovetail 2-4 (Figure 3) on its upper surface in which a rectangular groove 26 is formed. In the groove 26 is a gib 2B. A pair of brackets 30 are mounted on the dovetail 24 so they may be equally spaced from the axis of turning 'of the table I8 and to which they are secured in predetermined spaced relation as by the screws 32 countersunk in the gib 28. These brackets support the wire 34 which passes through the aperture 3'6 in the bearing jewels 38, as illustrated in Figures 4, 5 and 6.

The upper ends of the brackets 30 are formed with diametrically positioned grooves 40 adapted to receive a rod 42 retained in position in the groove by clamp members 43. Spaced arms 44 depend from the rod 42, to which the arms are pinned, as at 46, to maintain a rigid relationship between the arms and the rod. These arms 44 depend downwardly and the free ends thereof are formed with grooves or slots 48 at their lower ends through which the ends of a wire 34 pass and which ends are secured to the arms as by the screws 50.

On opposite sides of the table l8 are diametrically disposed columns or posts 52 (Figure 3 which are secured to the base ID as by the bolts 54. On these columns is mounted a bridge member 56 extending generally transversely of the table I8 and immediately thereabove. This bridge member 56 is formed on its upper surface with a dovetail 58 guiding a slide 60. The slide 60 carries, longitudinally, a spacer 62 which is secured to the slide 60 as by the screws 64. Supported on the spacer 62 is a bead carrying member 66 shown as an elongated rectangular plate 66 formed with a plurality of longitudinal parallel grooves 68 receiving, respectively, the beads 10 (see Figure 4). The bead carrier 66 is shown as positioned on the slide 60 by means of pins 12 passing through notches 14 in the ends of the bead carrier 66 and seated in the slide 60. To the rear of the slide 60 there is mounted a fixture 16 formed with ears '8 to which a pitman 80 is pivotally mounted whereby the slide may be reciprocated.

The beads are rotated by relative movement between the bead carrier 66, actuated by the pitman 80, and fingers overlying and frictionally engaging the beads, the wire 34 being within the aperture in the jewel and in contact with corners or edges in the apertures. While the jewel carrier 66 is moved in one direction by the pitman 80, the reciprocating fingers 86 above the slide mounted, as at 81, on a bridge member which, for convenience, is illustrated as a composite member shown at the right in Figure 3, as well as in Figure 2. mounted, as at 81, on the bridge member and the bridge member and fingers are always moving in the opposite direction to that of the jewel carrier 66. This bridge member is illustrated as comprising a transversely extending block 8| from which rigid arms 82 extend in a horizontal plane on opposite sides of the spacer 62 and slide on the slide 60. These serve to guide the bridge in its reciprocation. Extending upwardly from the bridge block BI is an ear carrying portion 83 to the ears 84 of which are pivotally mounted a plurality of the so-called fingers 86 extending over the grooves in the bear carrier and overlying the beads in frictional contact therewith. The bridge is also provided with a rearwardly extending portion 88 formed with an ear 90 to which is connected a pitman 92. The two pitmen 80 and 92 are respectively connected to the ends of a rocking lever 94 pivoted as at 96 and actuated by a link 98 connected for reciprocation to some prime mover such as the disk Hi6 driven by the belt I62.

Extending upwardly from the bridge is a pedestal I04 carrying cam means I06 which will raise the fingers 86 up oiT the beads to permit their insertion and removal as will be understood. As illustrated, the cam member I06 is pivoted as at ID! on an ear I08 on the pedestal I04 and is of a length such that when swung downwardly, as by handle Ill], will depress the inner ends of the fingers, that is, the ends to the right of the pivot 87, as viewed, and retain the fingers 86 in an upwardly tilted position ofi the beads so that access may be had thereto for removal and replacement,

It will thus be seen that once the wire 34 has been threaded through the passages in the jewels 16 and they are disposed in the grooves 68, that the jewels will be caused to rotate about the wire by the relative reciprocation of the carriers and fingers. By turning the table H3 at an angle to the slide 60, the beads are moved to positions in echelon with respect to one another, as shown in Figure 6, whereby the wire is brought into contact with those edges of the passages which it is desired to round off, to the desired degree depending upon the angular movement of the table l8. Since the table is capable of movement with respect to the slide through a wide angle closely approaching half the circumference, any desired radius of curvature of the edges, within wide limits, may be effected and it may be said that universal movement of the wire with respect to the beads, or vice versa, is permitted by the fact that the beads are free to move in the groove, both longitudinally of the groove and rotatively with respect thereto with the wire at any permissive angular relation to the axis of the groove as well as to the axis of the jewels.

The fingers 86 are pivotally.

skilled in the art in the composition, configuration and disposition of the component elements going to make up the invention as a whole as well as the instrumentalities effecting relative movement of the several parts, some of which may be united in a single member for convenience in manufacture and assembly, and no limitation is intended by the phraseology of the foregoing description or illustrations in the accompanying drawings except as indicated in the appended claims.
