sermon-campfire machine,

Application filed Sap To all whom it may concern: I Be it known that I, WILLIAM HERZOGya: citizen of the United States, and a. resident of Garfield, in the county of Bergen and. State of New Jersey, have invented a new and Improved Button-Grinding Mac'hine,-

exact description.

My invention relates to machine, and a particular object'of in invention is to form perfect buttons'from sec onds by means of a machine'of simple construction containin relativelyfew parts, and which is adapter? to form buttons of different shapes and sizes.

With the above and other objects-in view, as will more fully hereinafter appear, the

details of construction and arrangement of parts hereinafter fullydescribed, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

' 7 but showing the shafts used'in forming flat-face buttons; Fig. 14 is an end view of the recessed shaft shown to the left of Fi 13; Fi 15 is a transverse section throu the axis of this shift; Fig. 16 is a side e vation of' a shank button; and Fig. 17 is an edge viewof a section of a grooved grindsuitable construction has extending upwardly from opposite-ends thereof, a pair of standards 20, m the upper ends of which is journaled a drive shaft 21. Looselv mounted upon one end-of the drive sha is a loose pulley wheel 22 and a driving pulley wheel 23, which driving wheel is actuated by belting 24 from-any suitable source of power. Loosely mounted centrally upon the shaft 21, is a swinging car- *riage 25, which carriage comprises a base plate 26 ositioned below and extending parallel with the shaft 21. Projecting u wardly from this base plate and loose y mounted on the shaft 21, are four supporting arms 27, 28, 29 and 30. The upper ends of these arms terminate in bearing bosses 31, 32, 33 and 34, and extending in alinem'ent through the bosses is a chuck spindle 35. Rigidly mounted upon the spindle 35 between the bosses 31 and 32, is a gear.36 permanently in mesh with a gear 37 rigidly mounted .upon the shaft 21, and correspondingly, between the bosses 33 and 34 and contactmg with the boss 33, is a gear 38 permanently inv mesh with a relatively broad gear 39 rigidly mounted upon the shaft 21. It will be seen that by this construction motion is transmitted from the shaft 21 to the spindle 35. The spindle 35 is interrupt- .ed betweenthe central bearings 32 and 33, to form a chuck member 40, the end of which is reduced, which reduced end has screw threads 41 thereon (see Fig. 7 and has a slot, 42 extending diametrically through theend 43; said slot being enlarged on'opposite sides of the center thereof to form apair of spaced apartapertures 451; engaging the screw threads 41 is a nut 44, and inserted in the apertures 451 are a air of spaced-apart pins 45, which pins are eld rigidly inplace by means of the chuck formed by the nut 44 engaging the split threaded end of the chuck member 40.

Thesepins are constructed to pass through the eyes 46 of the seconds. The opposite member 47 of the spindle has a pair ofspaced-apart apertures 48 in the edge thereof, into which apertures are positioned the pins 45. In order to facilitate the ejection of the pins, a slot 49 'is positioned in the end of the member 47 in rear of the apertures 48, and in order toseparate the chuck member from the member 47 the latter member is slidable longitudinally in the bearing bosses 33 and 34 against the action of a coil spring, 50, which coil spring has one end bearing against a washer 51 adjacent the bearing 34, the other end of which spring is in engagement with the side of the gear 38. In order .to bring the button 52 carried by the'pins into engagement with the grinding 'wheel or stone 53 hereinafter described, an arm 54 has one end pivoted by means of a pin '55 to an extension 56 projecting integrally from the rear of the face plate 26. This arm extends some niaterial distance to the front of the machine and terminates in a convenient handle 57, so that by raising the arm 54 by means of the handle 57, the carriage 25 may be swung on the shaft 21, to bring the button 52 into variable engagement with the grinding wheel 56. The extent of this engagement may be varied by means of a bolt .58 passing through the extension 56 and adapted. to bear on the top of the bed19'. This bolt is locked in position by means of a .lock nut 59. By means ofthis same arm 56, the belting 24 may be thrown from the loose pulley 22 to the actuating pulley 23, and vice versa, by means of a belt-throw 60,

which belt-throw comprises a strap-engaging loop 61 rigidly mounted on one end 0 a lever 62, to the other end of which lever is attached a bar 63 extending along the front of the machine preferably on a' level with the bed 19 and having a pair or upwardly-extending fingers 64 disposed on opposite sides of the arm 54. The bar 63 is guided in position by means of a guiding bracket, from which guiding bracket extends a pair of pins 56 disposed about opposite sides of the bar. It will be seen that by this construction the movement of the arm 54 to the right or left on its pivotal connection will throw the gear 38 and belt shifter into operative or inoperative position. y

To permit the application of the button to the revolving grindstone 53, a verticallyextending plate 660 is rigidly mounted on the bed 19 on the opposite side of the carriage 25 from the extension 56, andhas an L-shaped slot 67 therein, in which slot is adapted to be positioned the arm 54. It will be seen that when the arm 54 is in the horizontal. portion 68 of the slot, as shown more particularly in Fig, 3, the belt 24 is onthe loose pulley and this plate 660 looks the carthe wardly from the bed 19.

to withdraw the button from the revolving grindstone and to throw the belt on the loose pulley simultaneously, and, at thesame time, to separate the members 40 and 47, to remove the button without waiting for the spindle 35 to come to a full stop. This entire operation may be performed simultaneously by the actuation of the arm 54, and for this purpose, an L-shaped le-' ver 69 is fulcrumed by means of a 'pin '70 to the plate 660 and to one side ofthe vertical portion of the L-shaped slot 67. The upper end of the lever 69-is offset toward the carriage, as shown more particularly in Fig. 4, and pivotally mounted in the upper end of said lever is a roller 71 maintained in engagement with the front face of the gear 38 by means of a coil spring 72, which coil spring has one end attached to the plate 660 on the side of the slot 67 opposite the pin 70, the other end of which sprihg is attached to the outer end'of the horizontal leg 73 of the lever69, as shown more particularly in Fig. 2. This horizontal leg 7 3 extends across the horizontal portion 68 of the slot 67 so that forcing the arm 54 to the right, will swing the lever 69 into the position shown in Fig. 3, forcing the gear 38 againstthe action of the spring 50, thereby disengaging the apertures 48 from the pins 45, as shown in full and dotted lines in Fig. 7-, and permitting the removal of the button 52. It will be seen by this construction, assuming the button to be in engagement with the grinding wheel 53, that the depressing of the arm 54 in the horizontal portion of the slot 67, will withdraw the buttonfrom its engagement with the wheel,-and then moving the arm to the right into the horizontal portion of the slot, will simultaneously shift the belt 24 to the loose pulley and will withdraw the member 47 from its engagement with the pins 45. By means of this arm 54, the button ismaintained manually in contact with grindstone .53, butshould it be desired to g1vethis button any particular shape, a

former cam. 74 of suitable configuration, such as'shown in Figs. 6, 10 and 12, is rigidly mounted upon the .outer end of, the member 47, whichformer cam is adapted to engage upper end of astandard 76 extending uphe grindstone 53 is mountedin transverse alinement with the button 52 and is aroller 75 rotatably mounted upon thev referably mounted. at' -one end of a shaft ?7, which shaft is. journale'd in a floatin' chuck Z8 vertically adjustable in astandar stan ard is transversely adjustable on a track 81 extending rearwardly from the bed '19. The shaft 77 is rotated independently of 1 the rotation of the drive shaft 21, by

means of a pulley 82 rigidly mounted on may be modified to carry a lain-faced button such as is shown in l'gs. 13 and 16. For this purpose the end of the member 40 is recessed to form a pocket 84, the edge of which pocket is corrugated to form a crown edge 85 adapted to engage one face of the button. The end of the member47 is 'simi larly recessed, into which recess is disposed a rubber or fabric cushion 86 held in posi-' tion by means of a screw .87, which cushion is adapted to'bear' on the opposite face of the button 52. It will be seen by this construction that the spring 50 acting on the member 47 forces the button into engagement with the crown head 85, forming a clutch to hold the rotating button in engagement with the grinding-wheel 53.

Where it is desired to give a rounded edge to the buttons, a grindstone having a groove 88 (see Fig. 17) in its periphery, may be substituted for .the square edged stone shown in the other figures.
