METAL-TURNING MACHINE.
SPECIFICATION forming part of Letters Patent No. 753,158, dated February 23, 1904. Application filed July 2, 1902. Serial No. 114,155. (No model.)
To all whom it may concern:
Be it known that I, THoMAs W. R. MCCABE, a citizen of the United States of America, residing at Winsted, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Metal-Turning Machines, of which the following is a specification. I
The object of my invention is to provide a machine of the class specified having features of novelty and advantage and adapted for producing work of the required precision and nicety at a small expense of operation.
My invention consists in the combination of a stationary cam-holder and a table rotating thereabout, suitable tools being carried by the table and having operating-levers which are controlled in their movements by the cams.
My invention also embodies the details of the construction whereby the desired object is attained.
In the drawings, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a detail view of the turret-controlling devices. Fig. 3 is avertical sectional view showing the column on which the rotating table is located and the cam-holder. Fig. i is a plan view of the table and the cam-holder. Fig. 5 is a sectional view through one of the lathes. Fig. 6 is a detail view of the frictional drive for the spindle. Fig. 7 is a plan view of one of the lathes, showing in detail the operating mechanism.
I will describe in detail the construction of my machine,from which its operation will be clearly understood.
A is the column, upon which is mounted the table B, having the trough C. The table B is driven by the worm-gear 5 and the screw b, which is operated through suitable connections to the shaft Z2 which in turn is geared to the shaft of the pulley c. To the top of the column is fixedly secured the cam-holder D by means of the bolt (Z. As will be seen from Fig. 3, this cam-holder has a series of circumferential grooves a), in which are mounted cams (Z 2 for operating the lathe and tool-holder. On the table B are located a number of lathes E, as shown in Fig. 4:. These lathes are in general of the ordinary type of jewelers? latheS,
and the number employed is not material. They are equipped with the ordinary spindle l, tail-stock 2, frictional driving-clutch 3, and the chuck 4, as is clearly shown in Fig. 5.
Mounted on the table in operative relation to the lathe is the tool-holder or turret F, which is cylindrical in form and mounted in suitable bearings ff and carries the tools projecting radially therefrom. The bearings of this tur ret are mountedon a carriage having a compound slide toward and away from the lathe and lengthwise thereof, the part K moving toward and away from the lathe and the part K moving lengthwise thereof, being operated in a manner to be hereinafter described. The shaft on the tool-holder F carries at one end the ratchet G, which cooperates with a trippingpawl 16, carried by a reciprocating arm 17, which in turn is acted upon by the lever 18 through the pin 19. The lever 18 is pivoted, as at 20, and its free end is engaged by suitable cams, as shown at 21 in Fig. 2, which are so ar ranged that they will trip the lever and through the pawl-and-ratchet-wheel connection turn the turret so as to present the proper tools to the work at the proper time. Between these cams 21 are arranged spring pressed plates 22, against which the free end of the lever 18 rests, exerting a continual pressure on the turret, which tends to hold the tools down on the toolrest 23 and prevents their vibration or what is known as chattering.
Each lathe is driven independently, as by a motor M, and it is to be understood that the table is continuously rotating about the column A and the cam-holder D. All the motions of the lathes and the turret are controlled automatically by levers, with the exception of the tail-stock, which is operated in the usual manner by the attendant through the lever 7.
The frictional driving-clutch has the pivoted shifting lever 3, connected through the link 3 with the double-ended trip I-I, carrying the adjustable contact-pieces kit, which lie in diiferent planes. The chuck is opened by the lever 5, connected with the lever 6, and is closed by the spring 5 as soonas the lever 6 rides off of its operating-cam. The movement of the carriage K toward and away from the lathe is controlled by the lever 8, connected with it by the link 8 and having the contact-points 9 10, which are located in different planes. The lengthwise movement of the carriage K is controlled by cross-head 11, which works in the slot 13 and is moved by the trip 12, having the contact-points 14 15, which are located in different planes. Each contactpoint of the operating-lever has its corresponding cam properly positioned in the camholder so that as the table rotates the levers are moved by cams to perform their work at the proper moment.
But a single attendant is needed for this machine, and his position may be taken at a point about opposite the cam which operates upon the lever 6 to open the chuck through the lever 5. At this time the clutch 3 is out of engagement and the lathe-spindle is still. By throwing the tail-stock lever 7 a piece of work maybe inserted in the lathe. As the lever 6 rides off of its cam the spring 5 closes the lathe-chuck and the piece of work is securely positioned. The contact-point h of the trip H is now moved by its cam, throwing in the clutch 3 and setting the lathe-spindle in motion. Assuming that the proper tools are in position ready for the work and that the first operation is to top off the collars w y 2, which are seen in the piece of work in the lathe, the contact-point 9 of the lever 8 will next be engaged by its cam to move the turret-carriage up the proper amount. The contact-point 15 of the trip 12 will next be engaged by its cam moving the carriage K to the left through the cross-head 12 working in thegroove 13. This movement accomplishes the topping operation. The contact-point 14: is next engaged to. move the carriage K back to the right. The contact-face 10 is now engaged to withdraw the turret. The lever 18 through the pawl 16 engages the ratchet G and turns the turret to present a new set of tools, which we may assume are the tools for facing one side of each of the collars m 1 a. The contact-piece 8 is engaged by its cam and moves the carriage in performing the facing operation. When this is finished, the contact-piece 10 is engaged by its cam and the carriage withdrawn. The turret is turned again by the lever.18 to present a third set of tools, which may be for facing the other sides of the collars, and the bell-crank lever 8 is operated in the same way with the same results. may be presented for turning down the pinions at each end of this shaft. The several operations will probably have consumed most of the time required by the table in making one revolution. After the last operation is performed the contact-piece h is engaged by its cam and throws the clutch 3 out of engagement. The lever 6 now rides upon its cam and opens the jaw 4, the tail-stock lever 7 is operated by the attendant, and the piece drops out and a new piece is inserted, and the same sequence of operation is gone through again.
Another set of tools Each lathe is initially provided with a rough piece of work, and in its course of travel the necessary operations are performed' upon it, and when it returns to the place where the work was inserted a finished article is delivered.
In Fig. 4 I have shown several cams (Z mounted in the cam-holder. These cams are 'not arranged in any particular order, but are simply shown to indicate how they will look from a top view of the holder.
In describing the operation of this machine I have confined myself to the conditions to be met in finishing what is known as a clockpiniona shaft with the three collars m y .2. It must be evident that a large variety of work can be. done on a machine of this kind, it being only necessary to properly adjust the cams to move the parts as and at the time desired. All parts would operate in the same way, the adaptation of this machine for different sized and styles of work being merely a matter of readjustment.
