UNITED r STATES 5PATENT NEricEo MACHINE' FOR TURNING AND DRlLLlNG METAL.

SPECIFICATION forming part of Letters Patent No. 425,556, dated April 15,' 1890.

Application filed October 24, 1889. Serial No. 328.044. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM VATTIE, a citizen of the United States, residing at forcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Turning and Drilling Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specication, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to turning and drilling machines in which the pieces to be turned and drilled are fed to the machine through a magazine; and the object of my invention is to provide a machine for turning and drilling pulleys and other metalpieces which shall be automatic in its operation; and my invention consists in certain novel features of construction and operation of a turning and drilling machine, as will be hereinaftery fully described, and the nature t-hereof indicated by the claim.

Referring to the drawings, Figure 1 is a side elevation of a machine embodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 is a detail view of the wormshaft and its accompanying worin-gears. Fig. et is a cross-section on line c at, Fig. l, looking in the direction of the arrow o., same figure. Fig. 5 is. a cross-section on line Fig. 1, looking in the direction of the arrow b, same figure. Fig. G is an enlarged detail drawing of the feed-plunger. Fig. 7 is an end elevation of the same, looking in the direction of the arrow, Fig. 6. Fig. 8 is an enlarged detail drawing of the grip-bar. Fig. 9 is an end elevation of the. same, looking in the direction of the arrow, 8. Fig. 10 is'an enlarged detail drawing of the grip-cam. Fig. 11 is an enlarged detail drawing of the feedcam. Fig. 12 represents a roll or pulley after the same has been turned and drilled by my machine. Fig. 13 represents, on an enlarged scale, a det-ached central longitudinal section of that portion of the machine in the space about one inch wide on either side of sections line a: az, Fig. 1. Fig. 14C represents, on an enlarged scale, a front view of the cutter-head and a pulley in position therein being operated on 5 and Fig. 15 is a central section on linegy y, Fig. 14..

I have shown in the drawings my machine madedouble; but as one side of the machine is just the reverse of the other, the description of one side will describe the other side. Therefore it will only be necessary to describe one side of the machine.

In the accompanying drawings, l is the bed of my machine, upon which the head-stocks and stands for holding the various parts of my machine are secured.

2 is the driving-pulley, which is fast to the shaft 3, running in the boxes or bearings 4C of the head-stock 5, and receives its motion from a belt and counter shaft overhead. shown.) The gear Gis fast on the shaft 3, and, revolving with the driving-pulley 2, imparts motion to the two gears 7.

The gear 7 on one side of the machine, receiving mot-ion from ther gear 6, turns freely on the shaft 8, and has the face of itshub cut into teeth to receive the teeth of the clutchsleeve 9, which slides freely on the shaft S by means of the handle 10, and is kept from revolving about the shaft S by a key or feather. (Not shown.) Then the teeth of the clutch- 'sleeve 9 are engaged with the teeth in the face of the hub ofthe gear 7, the shaft S will revolve in the bearing in the head-stock 5 in a direction opposite to that of the shaft 3, and the velocity of rotation of the shaft S will be to the velocity of rotation of the shaft 3 as the number of teeth in the gear 6 is to the number of teeth in the gear 7. The mill or cutter head 11, of any ordinary construction and having the cutters 11 secured on the face thereof, is fast to the shaft S and rotates with it. The gear 2 is fast to the shaft S and gives motion to the worm-shaft 13 through the system of gears 1i, 15, and 1G. (See Fig. 4.) The gears 14 and l5 are fast together and turn freely on the pin 31, fast in the arm 32,which turns freely on the worm-shaft 13, and is held rigid to the bed 1 by the screw 33, Fig. 1. The velocity of the worm-shaft 13 can be altered by changing the gear la for one of greater or less number of teeth, and the slot 34 in the swinging arm 32 is to allow for change of position in bringing the two gears 12 and 14 into mesh.

The rotation of the worm-shaft 13 in the (Not y bearings 35 causes the revolution of the three cam-shafts 17, 18, and 19 by the

worms

20, 21,

and 22, fast on the shaft 13, (22 being shown in Fig. 2 by the removal of some parts ot the machine,) meshing, respectively, with the worin-

gears

23, 24, and 25, which are fast, respectively, on the shafts 17, 18, and 19.

The feed-cam 26 is fast on the shaft 17, held in the

bearings

36 and 37, Fig. 5, and by its lo rotation in the direction of the arrow, Fig. 1,

gives motion to the segment-gear lever 27, hung freely on. the pin 38 by the roll 28 at the lower end of the segment-gear lever 27, traveling freely in the groove of the cam 26. The segment-gear meshes with the rack 29 in the feed-plunger 30, ca-rried in the bearings 39 of the head-stock 40 and parallel with the shaft 8, causing the feed-plunger 30 to move in accordance with the shape of the cam 26, the zo rack 29 answering for a key or feather by passing through the bearings 39, and so preventing any rotating movement of the feedplunger 30.

Figs. 6 and7 show an enlarged detail drawing of the feed-plunger 30. The plunger 30 l is hollow, and the central part of the chainber 41 is so large that the drill-carrying spindle will not touch it, but will bear only at the end of the feed-plunger toward the mill y 3o or cutter head at the smaller part 42 of the chamber, thus giving small friction-surface. The extreme end of the plungerV has a recess 43, of such a size as to freely admit the hub of the pulley to be turned and drilled,

- while the smallest part of the chamber 44,

which opens into the recess 43, is just the size of the drill used and is perfectly concentric with the outside of the plunger. The beveled end 45 of the plunger 30 is intended .1,0 to fit into and fill the inside edge of the rim of the pulley to be turned and drilled, and when the pulley is pressed upon the plunger 30 by the grip-bar the rough pulley is centered by the inside edge of the rim and the 45 hole is bound lto be drilled concentric with this inside edge, and consequently with the outside surface after the plunger has fed the pulley through the cutter-head 11. Therefore the result must be aconcentric and wellbalanced pulley.

The grip-cam 46 vis fast on the shaft 18, held iii the bearings 18', and revolves in the direction of the arrow, Fig. 1. The roll 46 travels freely in the groove of the cam 46, and imparts the motion of the cam 46 to the slidebar 47, which slides freely in the bearing 48 in a direction parallel to the shaft 8 and the plunger 30, and the motion is conveyed from the slide-bar 47 to the grip-bar 49 through the 6o fastening 50, made fast to the slide-bar 47 by the screw 51, Fig. 2, and holding the grip-bar 49 by the set-screw 52. lThe grip -bar passes through the hollow center of the shaft 8, and has a bearing only at the end near cutterhead 11 to give as little friction-surface as possible.

Figs. 8 and 9 show an enlarged detail drawing of the grip-bar. The end 53 has a recess 54 at the extreme end, of such a size as tofreely admit the hub of the pulley to be turned and drilled, and a still deeper recess 55 to receive the end of the drill when it shall have passed through the pulley. The extreme end of the part 53 is provided with notches 59, which fit loosely into the holes 56 in the web 57 of the pulley, Fig. 12, and prevent any tendency on the part of the pulley to rotate, the diameter of the end of the bar 53 being small enough to press against the web 57 of the spring 62 every time the pulley is grippedv and centered, and this compression will be greater or less, according to the imperfections in the different pulleys of acertain class and size.

The drill-cam 65 is fast on the shaft 19, held in the bearings 66, and revolves in the direction of the arrow, Fig. l. travels freely in the groove of the cam 65 and imparts the motion of the cam 65 to the slidebar 67, which slides freely in the bearing68I in a direction parallel to the shaft 8 and the' plunger 30. The motion of the slide-bar 67 is conveyed to the drill-carrying spindle 70 through the connection 71, made fast to the slide-bar 67 by the screw 72, Fig. 1, and forked at the hub 73, so as to allow the spindle 70 to turn freely within the fork.

' The drill-pulley 74 is fast ou the shaft 75,

which is carried by the bearings l7 6 in the head-stock 77. The shaft is hollow, and the spindle 70 is of a size to slide freelybackward and forward through it on a feather or key, so that thespindle 70 will revolve when the pulley 7 4 revolves. the end of the spindle 70 and has a bearing in the part 44, Fig. 6, of the chamber within the plunger 30.

The driving of the pulley 7 4, and consequently the rotating motion of the drill 78, is effected by a belt from a counter-shaft overhead, (not shown,) and is entirely independent of the motion of the main driving-pulley The roll 69 IOO The drill 78 is fast on 2, while the longitudinal motion of the drill 78 and spindle 70 is directly through the medium of the pulley 2.

'The rolls or pulleys 83 are fed to the machine by means of the magazine or feedbring the roll or pulley resting upon it in a line with the plunger 30 and grip-bar 49.

The operation of the machine is as follows: Supposing the drill-pulley 74 to be running and the magazine lilled, as represented in the drawings, by the pulleys S3, the feed-plunger 30 in its extreme rearward position, which allows a pulley to drop onto the shelf S2 between the plunger 30 and the grip-bar 49, which is advancing toward its extreme forward position. The pulley as it rolls from the end of the magazine is kept from falling onto its side by the pressure of the light flat spring S4, (see Fig. 5,) under which it has run by its own momentum, and which is fastened to the shelf S2 of the magazine The camshaft 17 turns in the direction indicated by the arrow and the plunger 30 advances and moves the pulley toward the cutter-head ll. The camshaft 18 turns in the direction indicated by the arrow and the grip-bar 49 advances to its extreme forward position and grips the pulley firmly against the plunger 30, thereby centering it with the cutter-head. The spring 62 in the grip-bar 49 is somewhat compressed, and thus allows for any Variation in thickness of the different pulleys. The plunger 30 starts forward rapidly at lirst, as the roll 2S on segment-gear lever 27 passes from the point a to the point b on the cam 26, Fig. ll, and the pressure of the flat spring 82 maintains the pulley in its upright position. The several cams are so timed that the grip-bar 49 arrives at its extreme forward position just before the cam-roll 2S reaches the point Z) on the cam 2G, and the firm gripping and the centering of the roll and the compression of the coil-spring 62 are the consequence. The plunger 30 and the grip-bar 49 now move together toward the cutter-head, carrying the roll firmly between them, and in passing through the cutterhead the pulley is turned to the required size. Meanwhile the shaft 19 has been turning in the direction indi cated by thc arrow, and the cam G5 is so timed thatthe drill 7S is advanced j ustas the pulley is gripped by the grip-bar 49. The shape of the drill-cam is much steeper than the feed-cam 26, causing the drill to overtake the pulley and pass through it, drilling a uniform hole concentric with the turned surface. The drill passes through the pulley and is withdrawn just as the pulley passes wholly through the cutter-head and drops down. Then the roll 45 on the slide-bar 47 reaches the point c, Fig. l0, in the cam 4G, the grip-bar 49 is rapidly withdrawn as the roll passes down the steep incline of the cam to the point d, and the finished pulley is allowed to drop below through the cutter-head into a box placed for its reception. The roll 28 of the cam 26 now passes from the point f to the point g, bringing the plunger 30 to its original position, and the roll 46 advances to the point h on the cam 46, and the operation is completed.

My machine above described is especially adapted for turning and drilling the rolls used on the pattern-chains of looms, one of which is shown full size in Figxl.

It will be understood that the details of construction of the several parts of my machine may be Varied from what is shown and described and equivalent devices used without departing from the principle of my in- Vention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a turning and drilling machine, the combination, with mechanism for gripping and centering the rolls or pulleys and mechanism for feeding them to the cutter-head, and means for operating said mechanisms, of mechanism for drilling the center hole in said rolls or pulleys and mechanism for turning the exterior surface thereof, and means for operating said mechanisms, all combined together and operated substantially as set forth.

XVILLIAM VATTIE.
