Definitions
- the present invention relates in general to a multi-axial work support and positioning device for use in the manufacture and repair of jewelry which greatly increases the efficiency of the jeweler in performing his work.
- the device represents a major advance in the equipment available to a skilled jeweler and thereby a corresponding increase in production and a reduction in costs.
- Emmert (709,399) is directed to a multi-jawed vise supported on a stationery base A and a heavy upstanding column C.
- the vise may be swiveled in a horizontal place through 360 degrees about the column C.
- the vise may also be swiveled bodily about horizontal axis d′. It may be adjusted further rotatably about a horizontal axis in bearing D.
- the Kapp patent (851,292) shows an adjustable bench pin 1, 29 mounted on a heavy work bench 9 by means of a clamp 2.
- Two swivel fittings 11, 16 and 32, 34, along with adjustable pin 26, permit the bench pin to be adjusted about a vertical axis and also about two different horizontal axes to accommodate the needs of the jeweler.
- the Rowland patent (1,446,811) shows a work holding clamp assembly consisting of a supporting bar or rod 3 mounted on a work bench or other support by means of brackets 1, 2.
- Spherical clamp connections 8, 13, 21, 27 support screw clamps 12 and 26 to hold relatively heavy parts for welding or other operations.
- the Merrell patent (4,295,640) shows a ring and bracelet mandrel arrangement adjustably supported upon an elongated rectangular base 14 and an upright holder 16.
- the patent to Reed et al. (4,595,186) is directed to a rotatable welding fixture for holding a pipe fitting against a welding table so that socket welds between the fitting and a length of pipe can be fabricated in one continuous operation.
- the unit comprises a small vertically adjustable work table fixed to a central depending spindle 16 which is rotatably and telescopically supported in an upstanding tubular column 13.
- a cube shaped clamping unit 30 is mounted on top of the table and provided with a series of different diameter dowels 36-39 to hold a pipe fitting such as an elbow in position for welding it to a pipe section 58.
- the cut-outs in the table such as the cut-out 63 may be used to permit a deck flange type fitting to be bolted solidly to the table for welding a section of pipe 80 to the flange 70.
- One object of the present invention is to provide a multi-axial work support and positioning device which greatly increases the efficiency of a jeweler in manufacturing or repairing jewelry.
- Another object of the invention is to provide a device of the character set forth above for use in the manufacture and repair of jewelry and capable of presenting an article of jewelry in numerous positions permitting work to be performed thereon.
- a further object of the invention is to provide a device of the foregoing type having a compact platen positionable rotatably and axially with work holding devices situated about the periphery of the platen so as to leave a clear deck area thereon for performance of the work.
- Still another object is to provide a device of the character referred to above including precision type work positioning and holding devices for presenting the article of jewelry to the craftsman.
- a further object of the invention is to provide a device of the foregoing type including means for moving the work holding device along three coordinate axes.
- a multi-axial work support and positioning device having 360 degree swivel motion which may be clamped in any given position about its vertical axis; the platen is adjustably positionable at a variety of selected positions along its vertical axis; work holding devices are situated about the periphery of said platen leaving a clear deck area thereon for performance of the work; and precision type work holding and positioning means are included for moving a work holding device along three coordinate axes.
- the device 10 comprises a platen 11 which in the present instance is of generally rectangular form with slightly rounded corners.
- the platen 11 has a central depending pivot shaft 12 with an integral hub 14 at the top which is secured to the underside of the platen as by means of screws.
- the pivot shaft 12 telescopically engages an axial bore 15 in upstanding column 16 which is fixed to a base 18.
- the column base which may be square or some other shape providing the necessary stability, is mounted on an underlying support surface such as a work table (not shown) and secured in place by hold down bolts 19.
- the platen 11 may be raised or lowered axially of the column 16 and retained in any elevated vertical position by means of the shaft clamp lever 20 on the column. The platen 11 may also be retained in any given angular position by means of the clamp lever 20.
- the clamp lever 20 is associated with a pair of bushings 21, 22 and a screw 24 rigidly fixed to the lever 20.
- the bushing 21 is disposed in threaded engagement with the screw 24.
- the column 16 and pivot shaft 12 may also include additional means for relative vertical and angular positioning.
- the pivot shaft 12 may be provided with one row of axially spaced diametrical holes 25, any one of which may accept a diametrical positioning pin 26.
- the diameter of the pin 26 may be on the order of 0.187 inch.
- the axial location of the pin on the pivot shaft will determine the height of the platen 11 relative to the column 16.
- the positioning pin 26 will engage the upper end of the column 16 and the platen can be turned to the desired angular position at the height dictated by the pin 26 and top surface of the column. Engagement of the clamp 20 will hold the platen in that position.
- the top surface of the column 16 may include a pair of relatively shallow V-grooves 28, 29 intersecting at an angle of 90 degrees. With the cooperation of the pin 26, this arrangement provides four distinct angular positions about the axis of the pivot shaft 12 and column 16. The platen can be quickly shifted from one such angular position to any other and then locked in the desired position by the shaft clamp lever 20.
- the platen 11 has four sides, 30, 31, 32 and 33 each equipped respectively with a specific auxiliary device for working on jewelry.
- One side 30 of the platen which in this instance happens to be longer than the two adjacent sides 31, 33, supports a device known as a bench pin 34.
- the latter is shown as a wedge shaped wood block which may have a V-shaped slot for use in temporarily holding a part to permit a filing or other tooling operation.
- the bench pin 34 is held against the underside of the platen by the bar clamp 35 and associated screws.
- the bar clamp 35 is designed to accommodate all sizes of bench pin.
- the shorter side 31 of the platen supports a small vise 36 which may be adjusted throughout a 180 degree rotational path (Figs. 1,8,9).
- the vise includes an inwardly projecting adjusting clamp 38 which slidably and rotationally engages a mounting bar 39 of circular cross-section fixed to the underside of the platen 11.
- the clamp is actuated by handle 40.
- the other longer side 32 of the platen has located thereon a ring size mandrel 41 (Figs. 1,1A,6).
- the inner end 42 of the latter has a pair of radially spaced flats 43 and is secured to the underside of the platen by means of a V-type mandrel clamp 44.
- the clamp comprises a V-block 45 swivel mounted on the underside of the platen 11, a pair of laterally spaced blocks 46,47 fixed to the underside of the platen, and a clamp bar 48 fixed to the blocks.
- a knurled knob 50 has a threaded stem 51 which engages a tapped hole in the clamp bar and aligned threaded sleeve 49, pressing the mandrel end 42 against the swivel block 45. Prior to tightening the knob 50, the mandrel and swivel block may be set to the desired angular position within the range of approximately 160 degrees in a horizontal plane. The knob 50 is then tightened, securing the mandrel in the desired angular position.
- an engraving head 54 may be mounted in the ring mandrel clamp 44.
- the engraving head has a clamp engaging section 42A with flats 43 substantially identical to that of the inner end 42 of the mandrel.
- the clamp engaging section may be secured in the clamp 44 by means of the knurled knob 50.
- a generally U-shaped bracket 55 is fixed at one end of the section 42A. The opposite end of the bracket 55 terminates in a captive ball 56 which provides a swivel support for the engraving head 54.
- a socket bore 57 Adjacent the remaining shorter side 33 of the platen, a socket bore 57 is located which receives an adjustable mounting 58 for a universal soldering clamp.
- the platen also includes two additional socket bores 57, one adjacent side 31 and the other adjacent side 32 for receiving additional universal soldering clamps. This permits the work to be held in any position or attitude to permit soldering of complex and minute pieces of jewelry.
- the platen 11 is also formed with a series of recesses 59, 60, 61 in its top surface extending parallel to and adjacent its longer side 30. It may also have additional recesses (not shown) adjacent its other longer side.
- the recesses are useful for collecting filings of precious metal or holding minute tools or components like stones and pearls incident to working on jewelry.
- a micro work positioner 62 is utilized (Figs. 10-13).
- the micro work positioner in the present instance is securely mounted on top of the platen adjacent the shorter end 33 thereof opposite from the vise 36.
- the work positioner 62 comprises a base 64 defined by a pair of opposed mounting blocks 65 connected by a pair of laterally spaced guide bars 66. The ends of the guide bars are slip fit into corresponding bores 67 in the mounting blocks and retained in place by set screws 69.
- Each mounting block 65 has a centrally located vertical bore 68 which receives an anchor screw 68A.
- Each screw 68A has a large knurled head and engages a threaded bore in the platen 11, thereby anchoring the work positioner 62 on the platen.
- the micro work positioner 62 includes a hollow, generally rectangular slide 70 formed with a pair of laterally spaced bores 71 which slidably engage the guide bars 66 and permit the slide to be moved longitudinally of the bars 66 between the mounting blocks 65 (Figs. 10, 12, 13, 20).
- the slide 70 is of inverted, generally U-shaped cross section in a direction perpendicular to the guide bars 66. It has a large central cavity 72 of generally rectangular shape and which is intersected by a pair of relatively short, laterally spaced guide bars 74 spaced vertically above the longer guide bars 66.
- a second slide 75 of stepped configuration is formed with a plate portion 76 generally coextensive with, and overlying, the top face of the slide 70.
- the slide 75 has a generally rectangular depending portion 78 integral with the plate portion 76 and somewhat smaller than the width of cavity 72 in a direction parallel to the guide bars 66.
- the depending portion 78 of the second slide 75 is rigidly connected to the short guide bars 74 as by set screws 79 in threaded bores 80.
- the short guide bars 74 and slide 75 are mounted for axial movement in unison relative to aligned bores 73 of the slide 70 (Fig. 13).
- the work positioner 62 further comprises an upstanding tubular guide 81 fixed as by means of a press fit within a vertical bore 82 in the central portion of the second slide 75 (Figs. 11-13).
- the tubular guide 81 is further secured in the bore 82 by means of set screw 77 and threaded bore 77A which communicates with the bore 82.
- Surrounding the tubular guide 81 is a telescoping sleeve 84 fixed to an oblong arm 85 as by means of a press fit.
- the arm 85 is precluded from turning by an upstanding pin 87 press fit within a bore 88 in the slide 75, and telescopically extending into an aligned bore 89 in the oblong arm.
- Two diametrically opposed set screws 86 are adjusted to position pin 87 in the center of the bore 89 with all relative lateral motion eliminated.
- the set screws 86 do, however, permit the arm 85 to move freely in a vertical direction with the sleeve 84.
- a biasing spring 91 is housed within an enlarged bore surrounding the tubular guide 82 and exerts an upward biasing force upon the oblong arm 85 and telescoping sleeve 84.
- the degree of vertical adjustment of the telescoping sleeve 84 relative to the fixed tubular guide 81 is controlled by means of adjustment knob 92 at the top of the guide 81 and sleeve 84.
- the knob 92 has a threaded stem 94 which engages threads on the inner bore of the tubular guide 81 to control the motion of the sleeve 84 along the guide 81.
- the work positioner 62 has a cross arm 96 adjustably mounted on the telescoping sleeve 84 (Figs. 10, 11, 13).
- the cross arm 96 has a transverse bar 98 adjustably supported in a bore through the cross arm.
- the bar 98 may be secured in a given position by means of clamping knob 99 and its threaded arm.
- One end of the bar 98 has a double swivel fitting 100 which supports the work holding tweezer fingers 101 (Fig. 10).
- Adjustment of the micro work positioner 62 may be initiated by starting with the approximate positioning devices. First, the slide 70 may be shifted manually in a horizontal direction along the guide bars 66 to a desired position. Next, the cross arm 96 may be positioned manually in a vertical direction on the telescoping sleeve 84 and secured there by tightening the coarse vertical adjustment knob 102. The transverse bar 98, swivel fitting 100, the work holder 101 may then be adjusted and secured by tightening the adjusting knob 99. The fine vertical adjustment is then made by turning the knob 92 in the proper direction to align the work holder vertically with another work holder. The fine horizontal adjustment is achieved by turning fine horizontal adjusting knob 103 which operates against the pressure of biasing spring 104 to align the work holder horizontally with the other work holder.
- a swivel fixture 105 the first figure an exploded view and the second an assembled view.
- the fixture 105 comprises an annular head 106 for receiving a work support unit such as the shellac pan assembly 108 (Figs. 16-18) or the ring clamp assembly 109 (Fig. 19).
- the fixture 105 has a mounting stem 110 similar to the stem 42 of the ring mandrel, or the stem 43A of the engraving head bracket (Figs. 14, 15, 18).
- the mounting stem 110 like the others, has a pair of opposed flats 43 for engagement by the mandrel V-clamp 44 on the underside of the platen.
- the head 106 has a reduced diameter extension 111 rotatably engaged within a bore 112 in the stem 110 and retained therein by means of tension screw 113 and bias spring 114.
- the bias is sufficient to hold the fixture head 106 in a given angular position which can be easily overcome manually.
- the head 106 When moved by the user to a desired angular position, which may be any angle within 360 degrees, the head 106 may be locked in that position by means of clamp screw 115.
- the shellac pan assembly 108 (Figs. 16, 17) is fashioned as a round metal holder comprising a heavy depending handle 116 surmounted by a cylindrical hub 118.
- the latter has a rim 119 of somewhat larger diameter with a shallow cylindrical recess 120 defined therein.
- the recess 120 is adapted to hold a shallow cylindrical pan 121 containing a body of shellac 122.
- the pan 121 has a peripheral groove 124 formed adjacent its base. Three knurled retaining screws 125 extending radially through the rim 119 engage the groove 124 to secure the pan in the recess 120.
- the holder without the shellac pan is inserted into the annular head 106 of the fixture 105 (Fig. 18).
- the cylindrical hub 118 has a snug sliding fit with the aperture 126 of the annular head and the lower face of the rim 119 seats firmly on the top face of the head.
- the mounting stem 110 of the fixture is inserted into the V-type mandrel clamp and the latter is tightened by the knob 50.
- the pan 121 which is made of aluminum alloy for rapid heat conductivity, and which has previously been filled with shellac that has solidified, is now quickly heated and the piece of jewelry to be worked upon is set partially into the shellac.
- the piece When the shellac has cooled, the piece is securely held in place and the pan is inserted into the cylindrical recess 120 in the holder.
- the retaining screws 125 are tightened to hold the pan in place.
- the fixture 105 is turned to the angular position desired by the jeweler and clamped in that position by the screw 115. The preparation for work by the jeweler is now complete.
- the knurled screws 125 are loosened and the aluminum alloy pan is removed from the cylindrical hub 118 of the holder.
- the pan is then heated and the shellac softens quickly, enabling the jeweler to remove the piece without difficulty.
- the small amount of shellac residue on the piece is easily removed with alcohol.
- a ring clamp 128 is there shown for use in the work fixture 105 described earlier herein.
- the ring clamp has a handle 129 surmounted by a cylindrical hub 130 with an aperture for receiving the upper end portion of the handle. The latter is retained in the hub 130 by means of set screw 131.
- the upper portion of the hub 130 is also formed with a rim 132 of somewhat larger diameter than the lower portion.
- the handle 129 has a large knurled-head screw 134 projecting from its lower end and which, when tightened, brings the clamping jaws 135 together holding the ring securely in place.
- the ring clamp 128, with the ring in place, may then be inserted into the annular head 106 of the swivel fixture 105 and angularly adjusted as in the case of the shellac pan assembly 108.
- the head 106 and ring clamp 128 may be clamped in that position by clamp screw 115 and the ring is ready to be worked upon by the jeweler.
- the ring clamp 128 is opened by loosening the clamp screw 134, the ring is removed from the jaws 135, and the ring clamp 128 is removed from the annular head 106.
