SPECIFICATION forming part of Letters Patent No. 696,629, dated April 1, 1902.

1. Serial No. 82,606. (No model.)

Application filed November 16, 190

To all whom, it may concern: Be it known that I, MAX GARBEIL, acitizen of the United States, residing in the city and county of Philadelphia and State of Ienn sylvania, have invented certain new and useful Improvements in Machines for Making Buttons, of which the following is a specification.

This invention relates to machines for the manufacture of buttons of mother-of-pearl, horn, or similar material, my principal object being to provide a simple and eificient construction and organization of mechanism whereby the application of the disks or blanks I5 to,their treatment upon, and subsequent removal from the machine may be expeditiously effected.

The invention, as generally stated, comprises a novel construction and arrangement of work-holding chucks and supporting and actuating mechanism therefor, together with tool supporting and operating devices and certain other novel features of construction and combinations of parts, which will be here- 2 5 inafter particularly described and claimed.

In the drawings, Figure 1 is a plan of ,my improved machine. Fig. 2 is a side elevation thereof. Fig. 3 is a transverse section, as on the line 3 3 of Fig. 1-. Figs. 4 and 5 are devel: o opments of the upper and lower gear-wheels, respectively, for effecting the intermittent rotation of the chuck-bearing shaft. Fig. 6 is a longitudinal section, enlarged, through one of the chucks and its adjuncts. Fig. 7 is an elevation of one of the chucks removed from its sleeve or casing. Fig. Sis a vertical section, enlarged, through the tool-holder and its supporting and operating parts, as on the line 8 8 of Fig. 1. p

A represents the supporting-frame, comprising the bed 1 and standards 2. 3 is the main shaft, having its bearings in brackets A on said frame and being equipped with the fast and loose pulleys 5 6, respectively. On the respective ends of the bed are pedestals 7, provided with suitable boxes 8, in which are journaled the respective ends of a longitudinally-disposed shaft 9. Keyed or otherwise secured on this shaft is a spiral gear 10 of special construction, with which coacts a special gear 11 on a lower transverse shaft 12, having its hearings in brackets 13 on the bed-plate. On one end of the shaft 12 is a bevelwheel 14, in mesh with a similar wheel 15 on a vertical shaft 16, having its bearings in abracket 17, depending from the bed-plate. The lower end of the shaft 16 carries a bevelwheel 18, which also coacts with a similar wheel 19 on the main shaft. Hence when power is applied to the main shaft the motion is transmitted therefrom through the intermediate gearing to the transverse shaft 12 and thence through the gears 11 and 10 to the longitudinal shaft 9. The construction of the gears 10 11 is such that the shaft 9 is intermittently rotated thereby and also temporarily locked at the end of each step or movement. In the presentinstance the shaft 9 makes one-third of a revolution during each movement thereof. The peripheries of the two gears are shown developed in Figs. stand 5, by reference to which it will be observed that at regular intervals the spiral or inclined teeth of the upper wheel 10 are reinforced and mutilatedthat is, at each place two adjacent teeth are thickened and foreshortened on opposite sides of the wheel to afford a transverse interdental space, as indicated at 10, and it will also be observed that the lower wheel is provided with a few spiral teeth only, the remainder of the periphery being provided with a circumferential rib 11. WVhen the teeth of the lower wheel are in engagement with the teeth of the upper wheel, the latteris rotated thereby one-third of a revolution; but when the rib of the lower wheel registers with the transverse interdental space such rib locks the upper wheel in place until the teeth reugage the teeth of the upper wheel, in which case the latter is turned another third of a go revolution, when it is again interlocked with the rib, as before, and so on the upper wheel is intermittently turned and locked by the lower Wheel.

Affixed to the shaft 9 are two heads 20, which conjointly constitute a chuck-bearing frame, in which are j ournaled at equidistant points from the axis of the shaft three rotatable sleeves 21, Fig. 6, each of which sleeves is provided in the space between the two heads with a flanged wheel 22. Passing about the uppermost wheels is a belt 23, which also passes around a large driving-wheel 24 below the bed-plate. The wheel 24 is carried by a shaft 25, journaled in the free end ofa frame 26, which is sleeved on the main shaft. On the two shafts are sprocket-wheels 27 28, respectively, which are geared together by a chain 29, whereby the shaft 25 is positively driven from the main shaft and the motion is transmitted from the shaft 25 to thefianged wheels 22,about which the belt 23 passes,there by rapidly revolving the sleeves carrying said wheels. It will be seen that the frame 26 will rise and fall during the intermittent rotation of the chuck-frame and that the belt 23 will be thereby maintained in operative engagement with the two uppermost wheels in the latter frame.

At the inner ends of the respective sleeves are chucks 30, which are adapted to receive and hold button-blan ks. Each of these chucks comprises a longitudinally-split tube 31, provided with a screw-threaded portion 32, that is screwed into an internally-threaded portion of the sleeve. The split portion of the tube projects beyond the sleeve and constitutes a series of clamping-jaws, which are socketed, as at 33, for the reception of the button-blank. The normal tendency of the jaws is to separate or open, and hence means are provided to close the same and effect the clamping of the work therebctween. To this end the jaws are formed near their acting portions with beveled surfaces 34, which are embraced by a correspondingly-beveled annulus 35, which is slidingly fitted within the forward end of the sleeve. By retracting this annulus the beveled surface thereof coacting with those of the jaws will force the jaws to gether, and by returning the annulus the jaws being free will resume their open or normal position. Extending axially through the sleeve and thechuck-tube is a spindle 36, provided at its forward end with atransverse pin 36,which is connected with the annulus. The rearward end of the spindle extends outwardly of the sleeve and is provided with a collar 37, between which and the sleeve is interposed a stout spring 38, that tends normally to retract the spindle and annulus, and thereby close the jaws. By this construction it will be seen that the acting or clamping portions of the chucks occupy at all times the same vertical plane regardless of variations in the diameter of the blanks applied thereto and that therefore the position of such blanks in respect to the turning-tool (hereinafter described) to which they are presented is always uniform.

Rising from the bed-plate rearwardly of the chuck-frame is a post 39, provided with a cam 40, that lies in the path of the rearward ends of the spindles during the intermittent rotation of said frame. Thus the spindles successively engage the opposing cam and are pressed inwardly thereby to effect the release of the chuck-jaws. At each dwell of the frame the spindle is maintained retracted by the action of the cam, and the jaws controlled by the particular spindle are therefore in open position for the reception of a button-blank. In the next succeeding movement of the chuck-frame the spindle, escaping the cam, resumes its normal or retracted position, and the blank is thus clamped by and between the jaws. At the same time another spindle engages the cam and the above-described operation is repeated, and so on successively the advancing spindles engage and escape the opposing cam. Mounted on the bed forwardly of the chuck-frame and on the side thereof diametrically opposite to that where the cam is located is a slide-rest 41, to which is fitted a slide 42, carrying a turning bit or tool 43, that is designed to act upon and shape the face of the rapidly-rotating button-blank opposite thereto in one of the uppermost revolving chucks. The slide is reciprocated toward and from the chuck-holder at predetermined intervals in a manner to act upon the successive blanks during the stages of rest of the intermittently-rotatable holder. When the chucks are opened through the instrumentality of the cam 40, as above described,the turned buttons are removed there from by the attendant, and other blanks to be turned are then applied to the open chucks. In the present instance the slide-rest is provided with a rearwardly-extending rod 44, which is maintained yieldingly in contact with a cam 45 on the shaft 12 by means of a retracting spring or springs 46, secured to the slide and to one of the pedestals 7, the peripheral contour of the cam being such as to effect the progressive advancement of the slide toward the button-blank and then to release the slide to permit the spring to retract the latter. A set-screw 47, fitted in the slide, acts against the opposingextremity of the rod to permit relative adjustment between the rod and slide. (See Fig. 8.)

The tool 43 is fitted to an inclined guideway in the forward face of the slide and is therein adjustable in respect to the plane of the button-blank, as need may require. The butt of the tool rests upon a tapped block 48, through which extends a suitably-disposed set-screw 49, carried by a bracket 50, bolted or otherwise secured to the slide, whereby when said screwis manipulated the block may be raised or lowered, as desired, to accomplish the corresponding adjustment of the tool. This tool extends freely through a transversely-slotted bolt 51 in the slide, so that by properly turning the screw-nut 52 of the bolt the tool may be released preparatory to adjustment and may then be clamped in the predetermined position of adjustment.
