BUTTON-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 643,587', dated February 13, 1900.

Application-iisd May 11, 1899. Serial No.716,412. (No model.)

the invention is readily adaptable for dress-` ing, facing, drilling, and finishing machines.

The invention therefore consists in the combinations and constructions of parts set forth in the claims, and the accompanying drawings illustrate a button-facing machine embodying the invention and minor improvements incidental thereto, all of which will be clearly understood from the following description, taken in connection with said'drawings,;

in Which- Figure 1 is a side elevation of the complete machine. Fig. 2 is a rear elevation thereof.

Fig. 3 is a central vertical longitudinal section through the machine. Fig. 4 is a transverse section on line 4 4, Fig. 3, looking upward.

5 5, Fig. 3. Fig. is a sectional view of the n sleeve and chuck for holding the blank. Fig.

7 is a detail perspective view of a portion of the tool-carrier disk, showing the adjusting device for the sleeve in which the tool-holding tubes play.

The base of the machine, as shown, consists of a three-armed spider A, having a central hub in which is stepped and supported the lower end of a tubular shaft B, the upper end of which is guided and journaled in the hub of. a spider A', similar to the base, but inverted and supported on the latter by the connecting-rods A2, by which the frame is rigidly bound together.

On the lower end of shaft B just above base A is keyed a worm-gear C, which meshes with a worm C, the shaft of which is journaled in suitable bearings Oi., attached to the base A, as shown, and this worm-shaft 'is driven by means of a pulley O3 and belt c from a pul- Fig'. 5 is a transverse section on line ley d, attached to a large belt-pulley D and therewith journaled on a stub-shaft rigidly secured to a bracket D', which is adj ustably secu red to one 0f the uprights A2 of the main frame. On shaft B above gear C is also rigidly secured a pair'of disks E E', which are rigidly united and rotate as one with shaft B. In the peripheries of these disks are formed vertical journal-bearings having removable caps e', as shown, and in said journals are mounted vertical sleeves F, which are provided with collars F on their upper ends, by which they may be suspended on the upper disk E and extend through and below the disk E', as shown. Within these sleeves are button-holding chucks G, which extend entirely through the sleeves and are provided with split and tapered upper ends which project above the collars of the sleeve and are adapted to receive the button-blanks, while their lower ends are rounded oi, as shown. The chucks G are splined to the sleeves F, so as to rotate therewith, but are capable of longitudinal movement within the sleeve. The said chucks and sleeves are preferably constructed substantially as described in my application for patent on chuck, Serial No. 715,199, filed May 1, 1899, to which I refer for more particular explanation thereof. The sleeves F are provided with combined weights and pulleysfintermediate the disks E E, so that their weight will tend to hold the chucks down and cause the sleeves to close the chucks when the chucks are pushed upward through the sleeves, substantially as described in my aforesaid application. Y

Below the disk E and above the screw C' is an annular cam-plate I, upon which the lower edges of the chucks G rest. In the machine shown there are ten chucks, and this cam-plate I is provided with a raised portion I,extending for about two-thirds of its diameter, and with a depressed portion I2 for the remaining portion of its diameter, the upper and lower parts of the cam-plate being connected by the rising and falling portions/it". The cam-plate Il is fixed; but'it is obvious that as the series of chucks is traveled thereover each chuck will be alternately raised and depressed, according to whether it travels on the high or low portion of the camplate. A part I3 of the lower portion I2 of IOO the cam-plate is preferably made removable, and any chuck may be removed from the holder by simply rotating the latter until such chuck is over the part 13, which may be removed and permit the chuck to drop vertically out of the sleeve. By this means the chucks may each be removed and changed when desired with facility.

Upon shaft B, above plate E, is a tool-carrier disk J, having a number of tool-holders constructed substantially as shown in my application for tool-holder, tiled April 19, 1899, Serial No. 713,576, each holder having a vertical sleeve portion j, provided with a bifurcated tangy", which passes between guides Js upon the top of disk J, with its bifurcations embracing a bolt J2 on the disk. The guides J3 are provided with bolts J", by which the holder can be accurately positioned laterally. The tool-holding tubes K are vertically movable in the sleeves y', but in the construction shown are not rotatable and are provided with weights K', by which they are depressed by gravity, the construction and operation of these tool-holders being substantially such as is kdescribed in my aforesaid application, Serial No. 713,576.

The tool-holder Jisrctatable with the shaft B, but is capable of a slight vertical movement thereon to permit automatic sharpening of the tools. As shown, it is splined to the shaft B by means of a pin b, passing through a slot b' in shaft B and transtixing a shaft L within and extending above the upper end of shaft B and carrying on its upper end a large wheel M, which is ratcheted on its uppersurface, as at M', and is engaged by a dog m, connected to the upper end of a lever m', which is pivoted on an arm B3, projecting from shaft B. The lower end of this lever is adapted to contact with an adjustable bolt A, tapped into the upperspiderA', so as to oscillate the lever m' as it is moved therepast by thc rotation of shaft B. The position and extent of movement of lever m can be regulated by a screw m3, tapped through an extension B6 ou arm B3. The rocking of lever m' causes dog m to turn wheel M very slightly while it is being rotated with the shaft B, and thereby move shaft L longitudinally relatively to shaft B, and as shaft L is screw-threaded into the hub of wheel M, as shown at L, consequently each time the ratchet M is actuated by the lever m shaft L and tool-holder .l are lowered slightly. This is for the purpose of resurfacing or grinding the tools k after each operation, each tool being presented once during each of its orbital movements to the action of a grinder O, which is mounted on a stub-shaft O', having journals in a bracket O2, attached to the frame, and havinga pulley 03, by which it is driven by a belt ofrom a suitably-driven pulley o', also mounted on bracket 02, brackets O2 and 0- being adjustably secured to one of the uprights A2 of the frame, as shown.

Aare made fast in position.

A spring J5 may be interposed between the tool-holder J and the upper spider A' to assist in holding down the tool-holder, if desired. Between the tool-carrier J and the chuckcarrier (i. e., disks E E') is a tool-setting plate P, which is loose on the shaft B, so that it can be turned slightly thereon, although it willnormallyrotatetherewith. ltisprovided with a series of notches p in its periphery, whichv permit the chucks G to present the blanks to the tools 7i: during the normal operation of the machine. When it is desired to set the tools, the plate P is turned until its projections p' are opposite the tool-holders K, and then the latter are adjusted inwardly until the tools lo are stopped by projections p' on the setting-plate. Then the tool-holders This plate P therefore insures a proper setting of the tools in an easy and expeditious manner.

On two of the uprights A2 are journaled loose horizontally-disposed pulleys Q Q', and ou the intermediate upright, to which the bracket D' is attached, is another bracket R', provided with a stub-shaft, on which is journaled a belt-pulley R. The driving-belt S comes from a counter-shaft or prime mover (not shown) down under pulley D, is given a quarter-turn and led to and around the pulley Q', and thence is brought back partly around the periphery of the chuck-carrier to the other pulley Q and contacts the outer peripheries of the pulleysfof the several chucks intervening between the pulleys Q Q'. It is then brought back toward pulley R, given a quarter-turn, and passed around pulley R up to the prime mover, so that by a single belt a number of the chucks are driven. Only those chucks are driven whose pulleys f are brought into contact with that portion of the belt S between the pulleys Q Q', and those chucks whose pulleysfare not in contact with the belt will not rotate. As the machine is arranged all the chucks which are traveling along the raised portion l' of the cam will bc rotated during such travel by the belt S, While those of the chucks which are traveling over the part 12 of the cam-plate will not be rotating and will be open and may be supplied with blanks by the operator while passing along the portion l2 of the cam-plate. As the chuck travels over the rising portion z' it is lifted and its tapered upper end engages the tapered upper end of the bore of the sleeve F and lifts the latter, with its pulley, as indicated in the drawings, the weight of the sleeve and the pulley being sufficient to close the chuck tightly on the blank, as described in my application, Serial No. 715,199, aforesaid. As soon as the chuck reaches the upper portion l of the cam-plate its pulleyf strikes the belt S, and thus the chuck is rapidly rotated on its axis while it is traveling over the part l of the cam-plate. As the chuck reaches the descending portion t" of the cam-plate its pulley passes out of contact with the belt S, and consequently the chuck stops IIO rotating and the Weight of the sleeve and the pulley causes the chuck to drop, and as the chuck can drop farther than the sleeve, which is arrested by its collar F', it releases the blank, which is then removed mechanically. A suction-tube T may be employed to remove the blanks from the holders, as indicated in Fig. 1 of the drawings.

It should be particularly noted that each blank holder or chuck has its corresponding tool-holder, there being one tool-holder for each chuck, and such tool-holder always maintains its position relatively to the chuck-that is, it travels therewith during the operation of the machine. In the machine shown the tool-holder and the chuck-holders are supposed to travel continuously; but whether they travel continuously or step by step the tool-holder always moves with its chuck, and vice versa, and this. as stated at the outset, I consider a most valuable feature of the invention, because after the tool-holder is once adjusted relatively to the chuck there is no uncertainty in the operation, as there would be if the chucks presented the blanks successively to different tools or different holders were successively brought to operate in connection with the chuck. In my machine the chucks and the holders are in pairs, the same holder always Working with the same chuck, and vice versa,and it is this correlation and cooperation continuously maintained in the machine which I consider of the greatest importance therein and produces absolute` uniformity in operation and product.

To recapitulate briefly the operation of the machine,it is started andthe chuck-holder and tool-holder rotated, preferably continuously or step by step, and those of the chucks whose pulleys f contact with the belt S are rotated on their axes while they describe a circular orbit around the shaft. Those of the chucks Whose pulleys are free of the belt and are passing over the lower portion I2 of the camplate are ready to receive the blanks, which are fed thereto by the operator. Then as they ride up on the incline i the chuck is raised and in so doing is closed by the weight of its sleeve and pulley which is lifted by it, and as the chuck travels along part I of the cam-plate its pulley is brought into contact with the belt S and the chuck rotated and simultaneously the blank is brought into contact with the tool. The tool-holders being Weighted are free to drop by gravity until the blank is properly dressed. When the blanks first touch the tool, they lift it up and it cuts the blank more or less rapidly, according to the weight of the tool-holder, as described in my application, Serial No. 713,576, aforesaid. The trimming operation may continue during the entire time the chucks are traversing the portion I' of the cam-plate, which insures ample time for the complete dressing of the blanks. The descent of the tool-holder is limited, so that the blank cannot be injured if the cutting or dressing is completed before the chuck has traversed the part I of the camplate. When the chuck reaches the descending portion t', it opens and the button is removed and a new blank inserted, while the chuck moves along the part I2 of the camplate.

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