BUTTON-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 582,? 59, dated May 18, 1897.

Application filed February 9, 1893. Serial No. 461,593. (No model.)

To all 1071,0772, it nut l concern/.-

Be it known that I, WILHELM NAGEBORN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a certain new and useful Improvement in Button-Making Machines, of which the following is a specification.

The object of my invention is to reduce the cost of manufacturing buttons, especially those made from mother-of-pearl, although my machine is applicable to the making of buttons from bone, vegetable ivory, and the like; and my invention is an improvement upon machines havinga rotating table or support carrying the button-blanks, and particularly upon the machine invented by myself and George Carlyle, upon which an application for Letters Patent was filed May 23, 1892.

In carrying out my invention I provide a machine having several tools performing different operations which act upon two or more button-blanks simultaneously, each blank being operated upon by the different tools in succession,such machine being so constructed and arranged in its several parts that the blanks can be delivered to and removed from the machine with rapidity, and the several operations can be performed quickly and without unnecessary loss of time.

In its general features my machine consists of a series of traveling button-blank-holding chucks traveling, preferably, over and under or around a stationary table or support, the chucks being opened and closed at the proper intervals by the forward movement of the whole series. Above these traveling chucks and in line therewith are supported the rotating forming, centering, and drilling tools. These tools are held in chucks placed upon rotating spindles which are capable of a vertical movement toward and away from the traveling button-holding chucks simultaneously, which movementis imparted to them by a suitable frame which also acts as an end bearing for the spindles. This frame is depressed by a lever moved by the operator to bring the tools in position to act upon the blanks simultaneously, and when the operation is performed the frame and tools are returned to their normal positions by the pressure of the springs coiled around the spindles. The upward movement of the lever operates to release the pawls engaging with the traveling buttonholding chucks and operates the mechanism for moving said chucks, so that upon the next downward movement of the operating-lever the respective tools will act upon the next blank. Thus the different tools will act succcssively upon each blank and simultaneously upon different blanks. At the point where the blank is to be placed in the chuck the chuck rides over a cam situated in its path, which gives it an outward movement in its block, thus allowing its jaws to open. The blank is then inserted, and as the chucks are shifted along by the return movement of the operating-lever the one which has just received a blank rides off the cam and is forced backward in its block by means of a spring. The blank is then firmly held by the chuck. To release the completed button, the chuck rides over a similar cam placed so as to operate at a point under the table, so that when the grip on the button is released the button will drop out.

In the accompanying drawings, Figure 1 is a front elevation of the machine; Fig. 2, a partial cross-section and side elevation; Fig. 3, a top plan View, the tool spindles and supports and frame being omitted; Fig. 4: a central longitudinal section of the table and blocks of the blank-holdin g chucks,the chucks being shown in elevation; Fig. 5, a separate elevation of the table and blocks of the blankholding chucks and of the notched wheels which impart motion to the chucks; Fig. 6, an elevation taken on the line 6 6 of Fig. looking in the direction of the arrow, some of the parts being omitted; and Fig. 7 ,a section through one of the button-blank-holding chucks.

A is the table or support, constructed, preferably, of the form shown, and over or around which the blank-holding chucks B travel.

B are the chuck blocks or seats.

The table or support A in cross-section is constructed in the form of the letter H, as shown in Fig. 2, and rounded at the ends, as shown in Figs. 1 and 4. The side as has a flange so all around it which fits into slots 4) 011 the blocks 13. The other side of the table y has a channel y all around its outer side, and in this channel travel pins 10, which are rigidly held in the extensions wof the chuckblocks 13. The chucks extend between the sides of the table, and on the web .2, connecting the sides of the table, are formed the cams tand t, before referred to. The channel 3 and pins it serve to guide the chucks and seats around the table and also prevent them from falling awayfrom the table as they pass under it.

C are the spindles carrying the tools 1 to 5 and rotated by belt connection with the pulleys C, and D are the bearings through which the spindles work.

The bearings D are secured by screw-bolts to the supports E and E, so that the spindles may be given different positions relative to the button-blanks, as shown in Fig. 1.

F is the frame by the depression of which the tools carried by the spindles are brought into operative position.

The operating-lever G is pivoted at a to the post (Land is provided with a rounded lug b, resting on the lower cross-bar of the frame F. At the short end of the lever is a socket in which is placed a spring-projected pawl c, which engages with the ratchet-teeth e on the gear-wheel d. The wheel (I meshes with the pinion d, which pinionimeshes with the pinion (Z on the shaft 6. The shaft 6 passes through the table A and carries the notched wheel f. A similar wheel f, Fig. 5, is carried by the shaft 6', mounted in bearings at the opposite end of the table. The notches g on these wheels engage with the pins h on the seats of the traveling chucks. Under the top plate of the machine is a rock-shaft 1, supported in bearings 7a. This shaft carries locking-dogs Z and l, which extend through openings in the top plate and engage with the notches m in the chuck-blocks 13. Projecting downwardly from the rock-shaft 2' is an arm n, and between this arm and post a is placed spring 0. This spring acts to throw the dogs Z and Z into the notches m. Pivoted at p on the lever Gis a dog 1'), whichis thrown forward by a light spring q, secured to the lever G.

The bntton-blan k-holdin g chuck is formed, preferably, of three jaws, tapered on their outer surfaces for a portion of their length and held together at their lower ends by a collar '1'. An opening is formed through the center of the chucks into which the d rillin g-tools enter after passing through the blanks. \Vhen each chuck rides up onto the cam i, it is forced outward and the jaws of the chuck will separate slightly, and the button-blank is then placed in the recess u. A spring S is coiled around the cylindrical portion of each chuck between the collar 9' and the under side of the chuck-blocks, and when each chuck rides off the cam the spring forces the chuck back into the block, and by reason of the taper given the jaws of the chuck and the corresponding incline of the block the spring action will wedge the jaws together until they have a firm hold on the button-blan k. \Vhen each chuck rides up onto the cam t the same action takes place and the button will drop out.

The operation of the machine is as follows: A blank is inserted in the chuck which is at the moment on the cam 15 and the lever G is moved downward. The downward movement of the lever will cause the frame F to move downward, and consequently the tools 1 to 5. As will be seen in Fig. 2, the dog 12 is held against the arm n by the spring (1 when the lever G is in its normal position. The pressure of the dog p against the arm n in this position does not affect it, as the spring is of much less tension than the spring 0. In moving the lever G downward the inclined meeting surfaces of the dog 1) and arm n will slide past each other, and as the dog 12 clears the arm n the spring (1 will throw the dog 1) to the forward limit of its movement. The position of the lever G and the pawl c and dog 9) are now as shown in dotted lines in Fig. 2. This is the position when the tools are operating upon the blanks. There being, however, no blanks under the tools the lever is returned to its normal position to shift to the nextposition the chuck which has just received a blank. That is accomplished by raising the lever G, causing the pawl c and dog 1) to act simultaneously upon the teeth 0' and arm 72, respectively. The pressure of the dog 1) upon the arm 11 starts the pawls Z from the notches, and the power exerted on the wheel (I, through the teeth 0' and pawl 0, will rotate the wheel f, and consequently shift the blocks 13. The pawls Z and notches m being wedge-shaped the dog 1) simply acts to start the pawls l by its upward pressure on the slightly-curved end of the arm 'n, the pawlsl being forced entirely out of the notches by the shifting of the blocks 15. In the meantime the dog 2) will have been forced backward against the pressure of spring g by the further movement of the lever G, this being accomplished by the inclined meeting surfaces of the arm n and dog 17. The pressure of the spring 0 will keep the pawls 1 against the blocks 13 and force them into the notches of the succeeding blocks when they have been moved the proper distance. The next chuck is then in position to receive a blank, and as the lever G is moved downward tool 1 will operate upon the first blank inserted. \Vhen the operation is completed, the lever is returned, with the same result as before. This will place another chuck in position to re ceive a blank, and upon moving the lever downward again tool 2 will operate upon the first blank and tool 1 will operate upon the second. \Vhen this operation is completed, the lever is returned, as before, to its normal position and another chuck stands ready to be fed with a blank and the operation repeated. \Vhen the first blank inserted has been operated upon by tool 5, it is ready to be dropped from the chuck, and this is done when the chuck rides onto the cam t.

I do not limit myself herein to the use of the precise form of the table and button-holding chucks shown and described, as the same may be altered without departing from the spirit of my invention. Instead of the flat table shown a circular or oval-shaped support for the chucks may be employed, the operating-tools being placed at the proper angles.
