PATENT OFFICE.

CLASS S8: Pressing.

The improvements to the patent no. 40535 protected screw press consist of:

1. In the omission of the piston and the fixed nut, the latter by a movable one Nut held with two lugs by a crown fastened with bolts, is replaced, making it possible to give the press stand the shape of a gooseneck without giving intermediate ledgers.

2. In the reinforcement of the guides to be perfectly accurate and strict on the Get the base of the press guided frame.

3. In the reversal of the full part of the flywheel plate, in order to avoid that the lubricating materials with the friction plates, which themselves with washers or cheeks are studded with leather, come into contact; the leather strap attached to the flywheel is arranged, is thereby eliminated.

4. In the use of a lever with a counterweight, making the step in elimination comes and the changing mode of action of the press becomes completely automatic.

It is noticed, that · the head of the connecting screw is conical in the hub of the flywheel, whereby each wedge is avoided and that a horizontal crosspiece is applied so that the nuts of the crown which environmentally the nut conceives ^one, not twist which ensures perfect strength.

The improvements indicated above are from the accompanying drawing to see.

Fig. Ι is a front view of the press.

Fig. 2 shows a side view of the same and

Fig. 3 in vertical section the nut and the foot bearing of the screw spindle.

In these figures, P and P ^{1 are} disks, the inner jaws of which are respectively covered with leather ρ. p ^{1 are} occupied. These come into contact with the flywheel M , the hub of which is connected to the conical head ν of the screw V without being wedged. The movable nut V ¹ belonging to the screw is provided with two lugs and is held by a crown B ¹ . This arrangement makes it possible to give the stand B the shape of a gooseneck and to omit the intermediate bolt D specified in the main patent. A cross piece χ secures the nut against rotation (Fig. 1). The locking screw g goes through the full part of the pan C, which is precisely fitted in two parts in the crosspiece / press and countersunk in the same, and the guides nn ¹ have a larger diameter in order to form a perfectly rigid frame which exactly opens the base of the press is performed.

The full part m of the flywheel plate M is reversed to prevent the lubricating or other materials from coming into contact with the inner jaws of the disks PP ^1. To press some products, inventors use an arm with a counterweight f ¹ on the lever /, which means that the step J indicated in the main patent is no longer necessary.

Claims (1)

Patent claim: At the by DRP No. 40535 protected screw press, the replacement of the solid mother C through a held by the crown B ¹ traveling nut V ¹ for the screw F, which bears on top of a conical part of the flywheel plate M without wedging, and the replacement of Fufshebels J through the with arm and Counterweight f ¹ connected lever /, in order to be able to produce the stand of the press in the form of a gooseneck without the intermediate bolt D , and furthermore the changing action of the press automatically and to make the frame necessary for lifting the form completely rigid. For this purpose ι sheet of drawings.
