Specification of Letters Patent.
Patented Feb. 20 1917.
Application filed. May 4, 1916. Serial No. 95,392.
To alt whom it may concern:
Be 1t known that I, LOUIS Lane, a citizen of the United States, residing at 33 West F ifty-first street, Bayonne, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Setting-Gages for Prong-Cutting Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
The present invention relates to a gage for accurately setting a jewelmounting in the proper relation to a cutter for forming prongs upon the mounting to retain'the jewel thereon.
To form the prongs in such a machine, the ring or other article of jewelry is furnished with a mounting in the shape of a cup of metal having walls of suflicient thickness to furnish the prongs, and the present invention provides a gage adapted to fit within the cup when the holder carrying the ring is suitably set in the machine, so that the axis of the cup will be in line with the cutter and the cutter thus enabled when traversed repeatedly across the cup in different angular positions, to remove the metal between the several prongs and leave them standing in their desired position.
A prong cutting machine of such character is fully shown in my prior application No. 7 9,554 filed February 21, 1916, for patent on automatic prong cutting machine, and I have shown a part of such machine in the annexed drawing, to illustrate the relation of my improved gage thereto;
In the said prior application I showed a slide movable longitudinally beneath the cutter and a carrier mounted upon the slide and furnished with a vise or holder to sustain the ring or other article bearing the mounting.
The gage described in said application for setting the mounting, is wholly detachable from the carrier and requires to be applied and fitted to the mounting manually; and the object of the present invention is to furnish a gage which is constantly sustained in the proper relation to the cutter so that when the mounting is retracted from the cutter it may stand below the gage, and the mere depression of the gage into the mounting serves to center it so that it can be securely fastened upon the carrier in the right relation to the cutter. v
The invention will be understood by reference to the annexed drawing, in which Figure 1 is an elevation of part of the head of a milling machine with the apparatus for sustaining the jewel mounting beneath the cutter, and the gage mounted upon an arm projected above the cutter-arbor;Fig. 2 is a plan of the arm with the gage-carrier thereon; Fig. 3 is an end view of thearm with the gage-carrier mounted thereon and the guide for the gage-spindle shown in section; Fig. 4 is a section on line ww in Fig. 1.
T Figs. 2, 3 and 4 are upon a larger scale than Fig. 5 is a plan of the apparatus with the parts above the cutter a omitted. Fig. 6 is a horizontal section at the top of the guides f in Fig. 1.
Of the parts shown in my prior application 6 designates the rotatable carrier, and c the jaws of the vise, provided with hinged clamping pieces 0 for holding the ring 6. d is the slide which sustains the carrier, 7 are guides to control the movement of the slide upon a base 9, and h a pan in which the base is supported upon the table A of the milling machine.
The front end of the head B of the milling machine is shown in Fig. 1, carrying the arbor C upon which the cutter a ismounted to form the prongs upon the mounting a. A hand-lever i is shown to reciprocate the slide 5 upon the base 9, to traverse the mounting a beneath the cutter a, and means is provided to partly rotate the carrier 6 upon each retraction of the mounting from the cutter.
When thus retracted, the slide is arrested at the same point by a stop-screw t, and the slide is set in this position when the ring or other article of jewelry is to be clamped by the jaws 0.
At such time the gage is applied to the mounting upon the ring during the clamp ing operation, to set the axis of the mounting in an exact line with the edge of the cutter a.
Means for automatically rotating the carrier upon the slide is shown in Figs. 6, the same as in my prior application.
The carrier is provided with a cylindrical shank b fitted to rotate in a hole in the top of the slide d (which in Fig. 6 is not shown as it is removed by the section plane) and the means which rotates the carrier operates automatically at each reciprocation of the slide by the successive engagement of a series of pins 6 upon the shank b, one of which pins contacts at each reciprocation with a pawl Z pivoted on the base 9. The stopscrew 6 limits such retracting movement which exposes the mounting for insertion in or removal from the vise.
The usual arm D is shown carried upon the head B above the arbor C, and the improved gage is mounted upon such arm and its parts designated by numerals.
1 designates the gage, carried by a chuck 2 upon a gage-spindle 3 which is preferably movable in a guide-tube 4. Such tube is attached to aearriage 5 which is slotted to move longitudinally upon a block 6 having a foot '7 mortised into one side of the arm D, as shown in Fig. 4. The block is held adjustably in the mortise by bolts 8 and is provided with a flange 9 upon its outer end to embrace the carriage.
The carriage is provided with set-screws 10 which are fitted to seats 11 upon the side of the arm D, and which set-screws in conjunction with the bolts 8 enable the block and the carriage to be adjusted laterally upon the arm. I
A set-screw 12 is inserted in the end of the carriage to bear upon the end of the block, to adjust the carriage longitudinally upon the arm. These lateral and longitudinal adjustments enable the operator to set the gage 1 exactly in line with the edge of the cutter,
1 as shown in Fig. 1, and thus when the gage is applied to the mounting, the mounting will be set so that the cutter crosses the axis of the mounting, and upon the successive shiftings of the mounting, will transform it into prongs of uniform size.
As the mounting'upon a finger ring is often very small, it will be readily seen that a slight deviation from the axial agreement of the parts will make. the cutting of the prongs lop-sided and their dimensions quite unequal.
The spindle 3 is held normally raised by a spring 13, its upward movement being arrested by a pin 14: which contacts with a collar 15 in the top of the spindle-guide 4.
The spindle is depressed by a hand-lever when applying the gage to the mounting. The bottom of the spindle is provided with a chuck 2 having jaws adapted to grip the shank of the gage and thus to receive gages of various sizes required for setting mountings of different dimensions. Such chuck furnishes a means of rapidly substituting one gage for another whenever required.
The arm D of the milling machine is in practice adjustable longitudinally upon the head and secured when adjusted by a setscrew D; but no such adjustment is employed in the present case, as no means is provided for moving the arm with such "delicacy and accuracy as can be effected by the set-screw 12.
The ring is moved under the cutter after each partial rotation and then retracted from the cutter to permit another rotation, and it is in such retracted position that the ring is applied to the carrier and clamped thereon.
Prior to such clamping operation, the gage is pressed downward to enter the cup of the mounting, and thus sets the mounting in the desired position and holds it there during the clamping operation.
Fig.- 3 shows the application of the lock and gage-carriage to one side of the arm D,
and Fig. 2 shows the application of the spindle-guide 4: to the side of the carriage, which construction brings the gage-spindle several inches distant from the center of the arm, and in a suitable position for the gage to fit into the ring mounting a, as shown in Fig. 3, when the mounting is retracted from the cutter.
Different cutters would be used for cutting large and small mountings, but the edge of such cutter would in all cases be adjusted over the center of the rotatable carrier Z) and the gage would therefore operate the same with all such cutters.
The longitudinal and lateral adjustments provided for the gage-carrier 5 enable the setting of the gage accurately at any time to the same center line.
Having thus set forth the nature of the invention what is claimed herein is:
1. The combination, with an arbor-head having an arbor and cutter, of a rotatable carrier having a ring-holder, means for manually reciprocating the carrier and holder to and from the cutter, a setting gage movable vertically over the holder when retracted from the cutter, and means for adjusting the gage laterally to place the same in the same vertical plane with the cutter, whereby to center the ring mounting in the holder relatively to the cutter.
2. The combination, with an arbor-head having an arbor and cutter, of a rotatable carrier having a ring-holder, means for manually reciprocating the carrier and holder to and from the cutter, an arm extended from the arbor-head over the ring holder and an adjustable setting gage carried by the arm and movable to center of the ring mounting in the holder when it is retracted from the cutter.
3. The combination, with an arbor-head having an arbor and cutter, of a rotatable carrier having a ringholder, means for manually reciprocating the carrier and holder to and from the cutter, an arm extended from the arbor-head over the ring-holder, a block mounted adjustably upon the arm, a carriage adjustable longitudinally upon the block, a spindle-guide upon the carriage with a spindle movable vertically in the same and carrying a setting gage, a spring to raise the spindle, the same.
4. The combination, with an arbor-head having an arbor and cutter, of a rotatable carrier having a ring-holder, means for manually reciprocating the carrier and holder to and from the cutter, an arm extended from the arbor-head over the ring-holder, a block mounted adjustably upon the arm, a carriage adjustable longitudinally upon the block, set-screws and bolts for adjusting the block and carriage laterally upon the arm,
'usting the carriage longiand a lever to depress a set-screw for ad] tudinally upon the block, and a spindleguide upon the carriage with a spindle movable vertically in the same and carrying a setting gage.
5. The combination, with means for prong cutting a finger ring mounting, of a carriage having a spindle-guide mounted thereon, a gage-spindle movable vertically in the guide and having a chuck adapted to removably hold diverse setting gages, and means for adjusting the carriage to center the gage over the ring mounting.
In testimony whereof I have hereunto set my hand.
