EDWARD N; MOOR, OF OAKLAND, CALIFORNIA TRAVERSE GRINDING, MILLING, AND DRILLING MACHINE FOR LATI-IES.

Specification of Letters Patent.

PatentcdSeptQZS,1913.

Application filed January 29, 1913. Serial No. 744,884.

To all whom it may concern Be it known that I, EDWARD N. Moon, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Traverse Grinding, Milling, and Drilling Machines for Lathes, of which the following is a specification.

My invention relates to the general class of lathe-attachments, and particularly to traverse machines adapted for such work as grinding, milling, drilling, etc.

The object of my invention is to provide a rigid, economically constructed and ad justably eflicient traverse machine of this class, and to this end my invention consists in the novel machine and in the construct-ion, arrangement and combination of its parts which I shall now fully describe by reference to the accompanying drawings, in which- Figure 1 is a front elevation of my ma chine. Fig. 2 is an end elevation, partly broken, of thesame, the spindle in the carrier being omitted. Fig. .3 is a section on the line 02-42 of Fig. 2.

1 is a rigid column which forms the stock of the machine. Through a central longituclinal bore of said column is fitted a bolt 2, the lower projecting end of which is formed with a foot flange 3 and its upper threaded end is fitted with ,a nut 4: which bears on a cap 5 on the head of the columnstoek. By retelring to Fig. '2 it will be seen that the column-stock is rig-idly clamped to and carried by the lathe-toolpost support 6, (.sutficiently indicated in dotted lines) by the foot flange 3 of the bolt 2 fitting the slot of said support, and by means of the. nut 4:, clamping the sup, port between said flange and the column foot. Thus the whole machine is firmly clamped to the tool-postswp ort, and may be readily fitted to lace anremoved; and by reason of the rigidity of the column, the whole device is rigid and stable.

About the column-stock 1 on a spline .or feather 7 thereon, as seen in Figs. 2 and 3, is fitted the split sleeve 8, adapted for accurate lineal movement or adjustment and to be rigidly fixed in the position to v which it is adjusted, by means of a bolt 9,

Fig. 3, through its meetin cars 10 at its The sleeve 5 when loosened for movement by relieving its bolt 9, is adjusted with facility and accuracy, by means of a screw 11. This screw, as seen in Fig. 2, has a handle 12 on its upper end, said end being seated in a lug 13 projecting from the cap 5 of the column stock and fitted with clamping nuts 14. The screw 11 is threaded through a nut 15 of the sleeve 8, and its lower .cnd finds a footing in a lug 16 projecting from the foot of the column stock. In order to define and accurately read the extent of the vertical or lineal adjustment of the sleeve 8, said sleeve is fitted with a pointer 17, as shown in Fig. 2, said pointer being itself adjustably carried in asoeket bearing 18 on the side of the sleeve and secured where adjusted by a set screw 19. The pointer 17 coacts with a vertical scale or line of graduations 20 on the column stock to afford the necessary readings.

The front of the sleeve 8 is formed with a boss 21 having a reduced portion 22, as shown in Fig. 3. Upon this reduced portion' is fitted and adapted to be turned for angular adjustment the annular body 23 of the spindle carrier 24. The carrier body 23 and the reduced portion 22 of the sleeve boss 21 have fitted to their faces the gage plate 25 the peripheral edge of which has angle-graduations 26, as seen in Fig. 2. A bolt 27 clamps these several parts together and fixes them rigidly in position. When the bolt 27 is loosened, the carrier-2 1 may be turned to an angular adjustment, the amount of which is readable on the graduations 26,. The gage plate 25 is anchored to the boss 21 by an anchor screw 28, shown in Fig. 1, and in dotted lines in Fig. 2.

The spindle carrier 24 is a split sleeve clamped by bolts 29 through its cars 30. In this carrier are mounted the spindle, the bushings, the chucks, the draw-in rod and such other arts as are usual. For the sake of illustratlon, I show in Fig. 1, the spindle 31, with its belt pulley 32, the bushing 33 the chuck 34 with its grinder 35, and the draw-in rod 36 with its handle 37. These parts illustrate a grinding machine though it must. be understood that for other work, such as milling, drilling, etc., the proper tools will be substituted for the grinder.

38 in Fig. 1 indicates an oil cup connection.

The up er portion of the carrier body '23 is forme with a split bearing 39 clamped by bolts 40.' This bearing is used for 'holding devices which form no part of the present application.
