This invention relates to a machine for duplieating and forming smallv articles, such as vwatch parts or. the 1ike.
An object of this invention isy to provideV a machine in the iorm of a small milling machine which will permit the formation of the various parts of a watchfrom a sample part, the newly formed part being produced with very close pre- CSion. v
Another object of this invention-is to provide ar machine of this kind which can be mounted on bench, or other plane surface and will quickly and accurately cut the work piece to the` desired configuration.
A vfurther object of this invention is to provide a machine. of this kind which includes interchangeable or positionable parts so that the sample holding chuck can be adapted to meet varying; conditions.
To theforegoingobjects, and others Which may hereinafter more fully appear, the invention consists of the novel constructionL combination and arrange,mentl ofY parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it isl to be understood that changes, variations, and modiiications may be, resorted to which fall within the scope of the:` invention as relai-med.

Figure 8v is a fragmentary planviewshowing the mountingr of severallattachments: on the des nice. l y
FigureQ is a sectional view taken on theline 9.9 of Figure 8..
Figure. 10 is a sectional view taken on the line lll-IIJ of Figure 8.'.
- Referrinate the drawings,l the numeral l5 designates generally a frame or basey which is formed, ef. opposite. end members l l and I 2..l the. end mem bei: ll' havingrubber ieet. I3 secured. to. an eut= wardly projecting flange I4. The end member l2 has rubber fet I5 mounted on the lowerend thereof. The end members Il and i2 are connected together by a pair of connecting bars I6 which hold the end members ll and l 2 in upright position.
A motor Il is mounted on a bracket I8 which extends upwardly from the ilange I4 and the motor Il has a drivingY pulley I9 in a lowermost position. The end mJnber l2 has mounted on the upper end thereof an inwardly projecting right-angular table 29 which provides a support for a rotary chuck generally designated as 2|. The chuck 2i is mounted in a bearing slee-ve 22 formed with an upper annular ange 23v engag` ing on the upper side of the table 20 andthe bearing sleeve 22 is secured against rotation by means of' a set screw or other fastening means 2d. Thetable 2li is also split or slotted as indicated at, 25 and a clamping screw 26 extends' across the slot 25 and co-'acts with the set screw 24 in irmly locking the bearing sleeve 2.2 in the table 26.
Thechuck 2i includes a. sleeve 2l which is rotatable within the bearing member 22 and the lower end of the sleeve 27 has a groove pulley 28A thereon about which a driving belt 2a engages. The belt. 29 is also trained about the driving pulley lvrotated by the motor il. The sleeve 2l' has mounted on. the upper end thereof a jaw contracting head 3e which is larger in diameter than the diameter of the sleeve 2l and rotatably engages on the upper side of the flange 2.3. The jaw contracting head .iiiV is formed with a tapered bore 3l within which a plurality of tapered jaws 32engage. The jaws 32 are carried by a threaded.
shaft or stem 33 which is threaded into the sleeve 2l and theshaft or stem 23 has mounted on the lower end thereof a knurled wheel 34 which is disposed below the sleeve 2i.
A stationary chuck, generally designated as 35, is also carried by the, table. 2li` at'one side ofi the chuckv 2i. Therstationary chuclc is adapted to hold a sample article in a position whereby' the sample may be duplicated as wiil be herein-- after described. The chuck 35 includes a sleeve 35 which extends through the tabley 2Q and is tightly secured relative thereto by means of a set screw 3l. The chuck 25 also includes a jaw contracting head 3B which is` formed with a tapered bore 39 within which work clamping jaws 4u, engage. Thev head 33 forms a shoulder 4l. at,
the lower end thereof which engages on the upper side of the table 2,6. Theiaws d have extending downwardly therefrom a threadedadiusting or.
jaw operating shaft 42 on which a knurled wheel 43 is secured below the sleeve 36.
A vertically adjustable tool holding table, generally designated as 44, is formed with a vertical front side 45 having a dovetail channel 46 within which a dovetail key 41 carried by the end member I2 slidably engages. The table 44 also includes a horizontal upper side 48 which is disposed in parallel relation to the table 20. The table 44 is adapted to be locked in vertically adjusted position by means of a shim 49 which is interposed in the dovetail channel 46 and is clamped against the tongue 41 by means of a pair of locking screws 59 on which lock nuts i are threadably mounted.
The table 44 is adapted to be vertically adjusted with precision by means of a micrometer adjusting member 52 which engages a threaded shaft 53 xed relative to the stationary table 28.V TheV micrometer table adjusting member 52 is disposed in a vertical position and extends above the horizontal table member 48. The table 48 is formed with a pair of openings 54 and 55 through which the chuck members 2| and 35, respectively, are adapted to project.
A tool carriage generally designated as 56 is slidably and adjustably mounted on the horizontal table member 48 and includes a base plate 51 formed with a dovetail tongue 58 engaging in a dovetail guide channel 59 formed in the table member 48. The channel 59 is disposed substantially centrally between the two openings 54 and 55 and extends to the outer end of the table.v
The carriage 56 includes a transversely extending tool rest or rib 6U which is formed with a pair of channels 6| and 62 within which a pair of tools 63 and 64, respectively, are adapted to engage. A clamping bar 65 engages over the tools 63 and 64 and is tightly secured relative to the rib 69 by means of a pair of bar securing members 66. The tool 63 is a cutting tool and is disposed in a position to intersect the vertical axis of the chuck 2l. The tool 64 is a follower tool and is disposed in a position to intersect the vertical axis of the stationary chuck 35.
Referring now to Figures 8 to 10, inclusive, in certain instances it is desirable that the sample article be disposed in depending position above the table 48. The chuck 35 is removed from the table 29 and is then disposed in an inverted position above the table 48. A vertically disposed supporting post 18 is mounted in an opening 19 formed in the table 48 and fixed in vertically adjusted position and in circumferentially adjusted position by means of a set screw 80.
A horizontally disposed bracket arm 8| is mounted in an opening 82 formed in the post 18 being endwise and circumferentially adjusted by means of a set screw 83. The arm 8l is formed with an annulus or head 84 at its inner end through which the sleeve 36 of the chuck 35 engages and the sleeve 36 is vertically adjusted in the annulus 84 by means of set screw 85.
Where it is desired to use an engraver or hand cutting tool for cutting the work piece carried by the chuck 2 I, a tool rest 86 is disposed above the table 48 and at.one side of the chuck 2l. The rest 36 is formed with a shank or arm 81 which engages through an opening 88 formed in a vertical supporting post 89. The supporting post 89 extends through an opening v90 formed in the table 48 and a set screw'S locks the post 89 in vertically adjusted position and in circum-` ferentially adjusted position. The shank 88 is fixed in endwise adjusted position by means of a set screw 92 which is threaded into the upperI portion of the supporting post 89.
In the use and operation of this device the work-i piece is clamped into the chuck 2l and is disposed in extending position above the table 44. The
motor l1 is connected with the source of electricl carrying the work power so that the chuck 2l piece will be rotated at the desired rate. The
sample work which is to be duplicated is-clarnped` into the chuck 35. The carriage 56 is adjusted horizontally and the table or vertically movable carriage 44 is vertically adjusted by the Vernier adjusting means 52. The tool 64 is a bluntl tool which is adapted to engage the sample work,
' whereas the tool 63 is a, cutting tool which will cut the work piece as the vertically and horizontally movable carriages are adjusted.
With a device of this kind exceedingly small articles such as are used in or form parts ofY Watches may be accurately and quickly duplicated and the finished Work piece will be precision made so that it will accurately t into the watch or the like in the same manner as the original article.
