BUTTON-MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,427, dated January 22, 1889.

Appncaaon med April 5, 1888. sei-aina. 289,675. (No model.)

To all whom it may concern:

Be it known that I, CARL AUGUST PFEN- NING, a subject of the German Emperor, residing at Barmen Rittershausen, in Rhenish Prussia, Germany, have invented a new and useful Apparatusfor the Manufacture of Buttons, of which the following is a full, true, and exact description, reference being-had to the accompanying drawin This machine consists of' mechanism for forming buttons, especially he'mispherical in shape.

Iteonsists, essentially, oit two parts-thebase for receiving the mold and covering material, called the button upper part, and the cover for receiving the shank or button lower part.

My invention will be readily understood from the accompanying drawings, in which- Figure llrepresents a sectional elevation 5 Fig. 2, a top view of the cover; Fig. 3, a detail of the button-raising mechanism, and Fig. it mechanism for altering the size of the stamp for differentfshaped buttons.

B represents a cap or cover, and E the base fitting the same. The cap B may be pivoted upon the lower part or arranged in any other way so as to assume the position shown in Fig. 'l for making'the button when it is to be locked upon the base. The base itself contains a cylindrical core, C', driven upward through the cylinder E by suitable mechanism-for instance, an eccentric upon a shaft. The cap B sustains the part i2, which is'provided with a peculiarshaped slot, r r2. Through the center ot' the part G2 traverses the plunger or stamp S, driven downward by a spring, s, as shown. The lower part of the cover B, which is somewhat expanded, contains the disk-shaped guide-plate p, which is vertically adjustable in this space, and the springs bears against the part G2 and the guide or part p. \Vithin the movable guide or part p is screwed the stamp S', which traverses the ifolding-die B, as shown. The part B is held in the part B by the pronged wire d, as clearly shown in Figs. l and 2. On the withdrawal of this wire a different-shaped part may be substituted, and a corresponding difference may be made by substituting a new plunger, C', or a plunger with a variable head to correspond to different-shaped buttons.

The part B has a bending-flange, g, as shown. Through the center of the stamp S and the plunger S passes the wire hook 7L. The end of this hook may be a hook, as shown, or, it' a clotlrshank button is used, a point to catch in that cloth shank. The upper end ot the stamp S is provided with atransverse slot, is, as shown, and the wire itself is lifted by the button h2, having a stem, h3, adapted to drop into the slot at one position ot' its revolution, and otherwise to be sustained upon the edge by pin s. A pin, s', supportedl in the stem h3, serves to rotate the stem h3 into the position when it will drop in the slot. In Fig. l the pin rests upon the top of S, while in Fig. 3 it has dropped within the slot. This revolution is accomplished by the engagement of the pin s upon the xed pin f2, fixed in the part G2, as shown. The part S is provided with slots p2, with which a key,U, engages, so

that different parts S can be screwed into the stem S.

The operation of my machine can now be readily understood. The mold and button are dropped upon the core, which is at first depressed. By turning thehandle h2 the hook 7L is dropped and the shank hooked upon it, the cover being raised. This position is shown in Fig. 3. The button h2 is then raised and the pin revolved into the position shown in Fig. 2, thereby holdin g up the shank until it is again dropped by the revolution of the stem i3. The machine is then closed upon the mold and surrounding material. The piston C is then raised to the height shown in Fig. l, and the handle R being turned to the position shown in Fig. l the pin s strikes upon the fixed pinf2 and drops the wire hook 71, into the position shown in that figure. The continued turning of the handle R after the button lower part has been dropped into the button upper part and pressed therein by the stamp S raises the stamp S out of the way, and the continued upward motion of the core C bends in, by reason ot' the bevel g, the metal mold and cloth forming the button upper part around and embracing the button lower parti tUpon raising the cover B, the hook h being in its lower position, the button islreadily detached.

NV hat I claim as my invention, and desire to secure by Letters Patent, is-

l. In a button-forming machine, a cylinder IOO Within which the button is formed, a core for raising,` the button therein, a stamp having its axis coincident with the core, and a hook for sustaining` the button passing through said stamp, substantially as described.

2. In a button-forming' machine, a movable guide and a stamp, S, supported and centralized thereby `and detachably connected thereto, in combination with the spring;I 3, actuating said guide, and the handle R', travelingl in the slot 0", fo'r elevating the guide and stamp, substantially as described.

3. The combination, in a lnlttom-forming machine, of the cap B, the button-forming part B', provided with bevel y, and the stamp S', depressed by sprin s and raised by handle R', traveling' in the slot r', lsnbstanti ally as described.

4. The combination, in a Mitten-'forming machine, of a stamp, S', and a central longitudinallyanovable button-holding' wire, h', substantially as described.

5. The combination, in a` button-forming machine, of the stamp S, provided at its upper end with a slot, a central button-supporting wire traversing' the stamp, and an arm at or near the upper end of said supporting-wire, whereby the latter may be sustained from the top of the stamp or be permitted to drop into the slot therein, substantially as and for the purpose described.

In. testimony whereof I have signed my name to this specification in the presence of two subseribingl witnesses.
