The present invention relates to a machine for attaching hinges Umbrella poles. 1 shows a side view and FIG. 2 shows a basic layout of the machine.

The purpose of the present machine is that which has been prepared and manufactured on another machine To provide the hinges, Fig. 3 and 4, sheet I, with a notch in the middle, and to bend the umbrella pole around. A 'notched hinge is in Fig. 5 and 6, sheet I, is shown, while Figs. 7 and 8, sheet I, the finished Show umbrella pole with bent hinge. Holding the hinge on the bar when pressing is done by pressing the same into corresponding previously attached Ver. causes depressions of the umbrella pole.

The machine at hand has to perform the following operation during one revolution:

After a hinge has been inserted into the clamping device S , this piece must be brought under the tool head by means of a slide mechanism. The clamping device is held in the position under the tool head until a notch is pressed into the center of the hinge, which is caused by the downward movement of a tool head. The latter also contains a second, longer tool of special shape, which in the same companionway results in the transfer of the notched hinge around an umbrella pole in a previous passage. While the larger and front tool holds the umbrella pole with a hinge, the hinge is completely attached to the pole by two pressure stamps attacking from different sides. The hinge located in the clamping device and provided with a notch is transported under the front tool by a slide mechanism, through which the hinge is pushed out of the clamping device when the tool head descends a second time, in order to bring about a suitable position of the hinge for inserting the umbrella pole. .

After performing these operations, the flywheel initiating the movement is disengaged and the machine stops. To the Preparation for the new next turn of the machine is punched and attached to the Hinge with trimmed edges inserted into the jig, and an umbrella pole placed over the notched hinge, whereupon the machine resumes its work, can "begin" as described above.

The machine consists essentially of a cast iron stand A, Fig. 1, with which all parts of the machine are connected. The movement is transmitted through shaft B by means of a flywheel, which is only indicated here and also serves as a pulley. Non-circular discs CDE, Fig. 9, 10 and 11, sheet II, sit on shaft B.

At the beginning of the operation, a hinge of the form shown in FIGS. 3 and 4 lies in a piece S, FIG. This piece S is also visible in Fig. 2 and has two slide rods s which end in prismatic pieces and one in corresponding openings

Claims (2)

Bed, connected. The rods s are also connected by a cross piece Q., Fig. 2, so that the parallel guidance is maintained under all circumstances. The piece 5 is moved to the shaft B with the aid of the slide rods s. This is brought about by two non-circular disks C, FIG. 9, seated near the bearings on shaft B. The disks, Fig. 9 to 1.1, are drawn as they sit against each other on the shaft. While the slide apparatus remains stationary, the nose provided with the disc E, Fig. 10, causes the head, provided with tools .W1W1 and guided in the stand, to go down. The tools wound W1 are shown in different views in FIGS. 14 to 19. The larger collar of the disk E causes; now a print with the stamps W Wj. The first stamp provides the hinge with a notch on a corresponding die. At the same time, however, the larger punch W1 moves downwards, taking a hinge provided with a notch during the previous rotation, over which an umbrella bar is placed, with it, until the hinge rests. During this decline, the hinge between tool W1 is bent around the umbrella pole. The duration for the pressure of the tools W and W1 is determined by the size of the. The arc of the largest diameter is determined, Fig. 10. While the tool W1 holds the umbrella rod in its lowest position, namely holding it on both sides of the hinge, the hinge that has already been bent is 13, pressed firmly around the umbrella pole from both sides at the same time. The movement of the plunger mechanism takes place from the shaft B by means of the disk Z), Fig. 11. The pressure is exerted by the protruding lugs of the disk mentioned and is only intended to serve as a completion work. The disk D moves the roller r firmly connected to the pressure stamp mechanism. In this way, the movement is transferred from the catch to the pressure stamp. The punch d is moved directly, the punch J1 indirectly, with the aid of a lever h fastened to the bed of the machine. In order to save space, the disc which carries the roller r is mounted on an inner disc F, which is loosely seated on shaft B, in such a way that the first disc with the entire pressure ram mechanism can make a reciprocating movement on the inner disc . The disk F is firmly connected to a rod q, FIGS. 2 and 13, which is guided in the stand A. The rod ends in an upper (o) and lower (u) prismatic part. which is guided in corresponding hollow forms of the bed, FIG. The middle parts of the bed above and below serve to guide the pressure ram mechanism. The retraction of the ram d {, which is not permanently connected to the lever h, takes place through a spring G2, which after exerted pressure, by virtue of its tension force, brings the pressure ram d1 back again. The return movement of the entire plunger mechanism is effected by a spring G located behind the shaft B and visible in FIGS. 2 and 13. When the rotating disk E, FIG As a result, the head rising and falling in the stand A only moves so far down that the punch W1 now pushes the hinge in the piece S, which was already provided with a notch in the first larger decline of the head, out of the piece S and in the position suitable for inserting the umbrella pole. The umbrella pole, on which the hinge is attached, is removed from the side. The return movement of the slide mechanism, the angle lever mechanism for moving the tool head, the pressure ram mechanism is carried out by the spring G1, which, like G and G2, can only come into effect when the lugs of the movement disks D and .is no longer act on the mechanisms concerned act. The flywheel, which sits on shaft B and also serves as a pulley, is automatically disengaged by a known mechanism after each revolution. During this time a new hinge is inserted into the piece S after compressing the spring f, FIGS. 2 and 12, and the machine can then work again. Patent-Α nsρrüch: A machine for fastening hinges to massive umbrella poles, which is characterized by the arrangement of the following essential parts: 1. a clamping device S., in which a hinge is inserted before the start of a machine rotation and is held in place by a clamping lever mechanism; 2. the connection of this tensioning device with a sliding mechanism, the latter with the help of non-round disks and springs or their replacement the back and forth Transporting the former back in order to get the hinge in a suitable position to bring the tools WW ₁ and temporarily hold them in this position until they have done their work;
the double downward movement of the tool head by means of an angle lever and a drive pulley on shaft B with two lugs, Fig. 10, of which the larger one brings both tools to action and by means of W the notch in the hinge, means W ₁ the pressing down of the umbrella rod and hinge, holding the former and bending the latter, and of which the smaller lug brings about the outside of the notched hinge from the clamping device and laying down the hinge over the slot to produce the later bend; the arrangement of two pressure stamps dd _1} by means of which the final pressing of the hinge around the umbrella rod is effected, the umbrella rod being held by the tool W ₁ during the pressure. For this purpose 2 sheets of drawings.
