MACHINE FOR ASSEMBLING THE PARTS OF BUTT-HINGES AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

To all whom it may concern:

Be it known that we, I-IERMANN STELLER and RUDoLr PIEPENSTOOK, subjects of the Emperor of Germany, and both residents of Oeckinghausen, near Karthausen, Westphalia, Germany, have invented a Machine for Assembling the Parts of Butt-Hinges and the Like, of which the following is a specification.

The present invention relates to a machine by means of which the parts of butt hinges as well as other hinges, and the like, are automatically assembled. The parts of the hinges, viz., the flaps, the pins and the knobs are fed through inclined channels onto a table where, by means of rams and slides, the two flaps of the hinge are joined to their knobs and secured to the hinge pin. Finally, the completed hinge is automatically expelled from the machine. All these operations are effected automatically and no other hand-work is required than the deposition of the parts into the feeding channels. Such deposition may, if desired, also be automatically efiected.

In the accompanying drawing the invention is illustrated, Figure 1 representing a plan of the machine, some parts thereof being shown by broken lines only, for the sake of clearness, Fig. 2, a side View of the same, Fig. 3, a cross-section on the line AA of Fig. 1, and Fig. 4, a View of one of the de tails of the machine.

The mechanical elements of the machine are arranged on a table top 1 which is supported on legs 2. On said table top four

rams

3, 4, 5 and 6 are arranged in horizontal position and in such a manner that each ram is parallel to another and in alinement with a third. The rams are slidably guided by means of their holders in bed-plates 7 and are moved in axial direction by eccentrics 8 slidably guided on the table top at right angles to the rams. The slides are tensioned, together with the levers, by springs 23, and the levels engage the cams by means of rollers 20.

The various hinge-parts are fed onto the table top by means of

inclined feeding channels

24, 25, 26, 27 and 28 which in Fig. l are shown by broken lines only. Any known automatic device may, if desired, be provided for supplying the hinge-parts to the channels. The channels are open at their lower ends so that the lowermost hinge-part always rests on the table top or on the special supporting plate provided thereon for the purpose.

The holder of the ram 5 has an off-set arm 31 connected thereto which arm, at the movement of the holder, engages the hingefiap 32 protruding through the channel 27 and places the same in front of the slide 21. Thereupon the latter moves and advances the flap so that its eye gets into alinement with the rams 3 and 5. These rams then approach one another, the former carrying with it a pin 30 from the feeding channel 28, and the latter a knob 29 from the channel 25. Both these elements are forcedby the ram into the eye of the flap 32 and secured thereto, the knob with its stem and the pin with half its length. The slide 21 acts on the flap by means of a U-shaped frame, the member 38 of which is disposed so as to move clear of the flap as long as no knob or pin is connected thereto. Down-turned lugs 39 (Fig. 4), however, while moving clear of the flap itself, engage the knob and the pin when these have been connected to the flap. After such connection, therefore, the flap will be advanced by the arm 38 so that the hinge pin gets into alinement with the rams 4 and 6. These rams, which have been at work meanwhile, now complete the hinge. An off-set arm 40, connected to the holder of the ram 4, engages the flap 32 protruding through the end of the feeding channel 26 and passes the same within reach of the arm 41 connected to the slide 22 which arm advances it into alinement with the rams 4 and 6. At the subsequent movement of the rams, the ram 4 takes a knob 29 from the end of the feeding channel 24 and forces said knob into the eye of the flap 32 simultaneously with forcing the latter on the hinge pin of the flap 32 which is disposed in the path. Finally the completed hinge is expelled from the machine by an arm 48, connected to a right-angled extension on the arm 41, and deposited through an aperture 44 in the table top into a suitable receptacle. The

arms

41 and 43 are disposed so as to keep clear of the flaps themselves and advance them by engagement with the eyes.

In order to secure the flaps firmly in position while the rams operate, the following arrangement is provided: A plate 35 is adapted to rock about a shaft 34, the rocking being eflected by a cam 87 mounted on the shaft 13 and cooperating with a spring 36. Lugs 33 and 42 on the free end of the plate are disposed so as to place themselves over the eyes of the hinge-flaps and prevent lateral movements of the same when the plate is acted upon by the cam 37. This is done simultaneously with the operation of the rams. The engaging surfaces of the lugs are grooved, as shown in Fig. 3, to coincide with the eyes, a firm hold on the flaps being thereby obtained. The paths followed by the various hinge-parts on the table, particularly those of the knobs 29 and of the pins 30, are also grooved so that no spontaneous movement of the elements takes place. The movements of the rams and of the slides are regulated so that the hinge-parts are put through the various stages of the operation in due order. While the rams operate for connecting the parts fed into alinement with the same, the arms 31 and 40 feed fresh flaps into reach of the

slides

21 and 22. The slide 21, while feeding one flap into alinement with the rams 3 and 5, feeds the previous one into alinement with the rams 4 and 6 by means of its arm 38. Similarly, the slide 22, while feeding one flap, by means of its arm 41, into alinement with the rams 4 and 6, expels the previously completed hinge from the machine by means of its arm 48. After the return movement of the rams and their arms, a fresh pin and fresh flaps and knobs are fed by the channels into operative position. In order to enable the elements to be correctly adjusted and to adapt the machine for hinges'of various sizes, the rams are connected to their holders by means of screws 46 passed through longitudinal slots 45. For the same purpose the

slides

21 and 22 are connected to the levers 19 by means of adjusting screws 47.

The described construction and combination of the elements may be modified within the scope of the appended claims without departing from the spirit of the invention. Machines of correspondingly modified construction may be used for the assembling of other kinds of hinges.
