Specification of Letters Patent.

Application led March `17, 1914. Serial No. 825,249.1A

To' 'all'whom itmay concern:

Bei-it known that iI," EDWARD Nl Moon, a citizen of the `United States, residing at @alsv landfinthecountyof Alameda and Stateoty California, have `invented :certain new and useful mprovements in1 Traverse-Machines for Lathes,of which the `followinglis a speci- Imation;-

My invention relates to the general class of llathe attachments and 'particularly to traverse-machinesadapted for suchwork as gear'-` cutting, milling," indexing, drilling, grinding, etc. My invention'is particularlyV adapted for and is applicable to that generaltypev of thesetraverse:attachments of *.vhich the-machinepatented by me September 23, 1913,' No.- 1,073,698,A is -an illustration, and my invention, in a sense, maybe consideredas anf'improvement on said machine, the general object of' the improvement` being to adapt-'saidmachine for a. variety of condi? tions and uses thereby making it more' elli cient.

To this end Emy invention consists in the'- novel machine and in the constructiomoar-4 rangement and vcombination of its parts which I shall now fullydescribeby reference toJ the accompanying drawings, in which'- Figure 1 is a yfront elevation of -my machine. Fig. 2 is an end View of the same. Fig. 3 is an elevation showing' the worm gearing.` Fig.4 is an elevation of my ina-- chine showing the spindle and its connec tions turned to a position parallel with the stock. Fig. 5 is a longitudinal section of the spindle carrier. Fig. 6 is an elevation of my machine showing the use ofa stepped pulley for variable speed driving. F ig. 7 is an end elevation of Fig. 6. Fig. S is a fragmentary view showing the spindle pulley. Fig.v` 9 is an elevation of my machine showing thev use of an index plate and index pin. Fig. 10 is an elevation, partly in section, of the same, taken at right angles to the elevation of Fig. 9.

1 is a rigid column which forms the stock of the machine. This column has passed through it longitudinally a bolt 2, the lower end of which has a foot flange 3 and its upper end a nut 4, bearing upon a cap 5 on the column head. By means of the footflange 3 the stock 1 is fitted to the lathe toolpost support in the usual manner and is clamped thereto by the bolt 2 and nut 4.

About the column-stock 1, on a spline or feather7 thereon, ist'ted the split sleeve S adapted for'i lineal adjustment on the stock, and to be'rigidly'fiied by means of screwbei'ng seated in a Ylug '13 projecting from` the cap 5.' The screw is threaded` througha nut-15 of the sleeve 8.

The sleeve r8 is formediwith a circular bearing face 16 having 'a central boss 17, andan annular "l'shaped slot-18. To--the circular bearing vface/1G is fitted the flangebody 190i thefsp'indle carrier'20.' The fitting -is onel which will'permit thevangular adjustment of the spindle carrier relatively tolthefbearing face 16 of the'sleeve 8, a pivotal connection'being made lby fitting the flange-body 19 rotatably upon thelcentral boss'17 of the bearing'fa'ce 1G. The connection is insured by a central bolt 21, and is rendered rigid in the various angular adjustments, bythe three bolts 22 which have their heads fitted in the annular slot-18 of said bearing 'facef16- Thecentral bolt 21 and two of thefbolts 22, flanking 'the-cen# tral boltyfrm a line of bolts which are `made to serve the double 'purpose of'holdingl thel bearing 4face 16 and the flange body 19 together, and ot serving to clampthe split spindlecarrier together at its meeting edges, as shown clearly in Fig. Ll.

23 is an arm which by means of a `split foot-clamp 23" is rotatably fitted upon the spindle housing 24 which is clamped-in the spindle carrier'20. The arm is Xed in any angular position to which it may be adjusted, by means ot'a bolt 25 in its footclamp.- The'arm'23is slottedat 26in'a radial line having the spindle carrier for a center. Thisarm A3 serves as a holder for adjustably attaching various devices to be used in the many operations and positions of which the machine is capable. Thus in Figs. 1, 2 and 3, I show this arm in connection with a spindle driving mechanism, adapted to be operated by an overhead countershaft.

27 is a plate which carries a short shaft 28, with a pulley 29 to receive the power. The shaft 28 has a worm 30. The plate 27 is carried by the arm 23, being clamped thereto and adjustable in the slot 26 thereof by the back plate 31 and the bolts 32 which pass through and are adapted to move in said slot. The worm 30 engages with a Patented Oct. 6, 1914.-

worm gear 33 on the spindle 34 of the machine. rlhe adjustment of the shaft 28 provides for varied distances from the spindle axis and, therefore, for Various diameters of gears Whether of the Worm or spur type. Also the angular adjustment of the arm 23 about the spindle housing serves as a belt tightener for the overhead belt.

As l have shown in Fig. 4, the spindlecarrier together With all its connections may itselil be adjusted to various positions, as, for example, parallel With the stock, by turning its body flange relatively to the bearing face of the sleeve 8.

In Figs. 6, 7 and 8, I shoW the slotted arm 23 as having applied to it a belt and pulley transmission of the stepped-pulley type, for'variable speed. In this case a stepped pulley 35 is carried on a short shaft 36, adapted to be adjusted in the` slotted arm and fixed thereto by a nut 37. 38 is the belt from an overhead countershaft to a pulley 39 on the shaft 36. 39 is a belt from the stepped-pulley to a pulley 40 on the spindle 34.

ln Figs. 9 and 10, I show the use of the slotted arm 23 in connection With an index pin 41 adjustably carried therein, as seen in Fig. l0, and an index plate 42 carried on the spindle 34.

rShe spindle housing 24 Which is clamped in the spindle carrier 20 is shown in Fig. 5 as containing the spindle 34, with its pulley 40, the bushings 43, the chuck 44, and the draw-in rod45 with its handle 46.

ln the several figures, the tool of the spindle is shown with abrasive Wheels 47. though it is to be understood that other tools may be substituted, according to the Work, such, for example, as circular milling cutters, fly-cutters, drills and drill-chucks, etc.

I claim l. A traverse machine for lathes comprising a stock with means for securing it to the lathe member; a member fitted to said stock for lineal adjustment thereon; a spindlecarrier carried by said member and angularly adjustable With relation thereto; a

spindle-housing 'clamped in the carrier', and having a tool-operating spindle therein; an arm carried by and radially extending from the spindle housing, said arm being angularly adjustable on said housing; devices adjustably carried by said radial arm; and devices carried by the spindle and coacting with the devices carried by the radial arm.

2. A traverse machine for lathes comprising a stock With means for securing it to the lathe member; a member itted to said stock for lineal adjustment thereon; a spindle-carrier carried by said member and angularly adjustable with relation thereto; a spindle-housing clamped in the carrier, and having a tool-operating spindle therein; an arm carried by and radially extending from the spindle housing, said arm having an elongated lineal slot and being pivotally mounted for angular adjustment on said housing; devices carried by'said arm and adjustable in the lineal slot thereof; and devices carried the spindle and coacting With the devices carried by the radial arm.

3. A traverse machine for lathes comprising a stock With means for securing it to the lathe member; a member fitted to said stock for lineal adjustment thereon, said member having a circular bearing face; a split-car` rier for the spindle, having a flange-body, a central bolt passing through the meeting edges of the split spindle carrier to clamp said carrier, said bolt also passing through the flange-body of the spindle carrier into the bearing face of the lineally adjustable member to pivotally connect said parts; and lateral bolts also clampingv the spindle carrier and passing through the flange body into the bearing :tace and having a circular play in said face. l

In testimony whereof l have signed my name to this specication in the presence of tWo subscribing Witnesses.
