  • the guiding means cooperating with the crank may consist of a rotary rod connected with the crank said rod being also adjusted to the frame or to another xed part.
  • the crank may be eccentrically connected to the driving means of the stamp thereby obtaining that the stamp will move on a little so as to provide or increasev the pressing pressure at the time when the one end of the driving rod of the stamp remains in its position.
  • a-simple apparatus with a reduced number of mobile parts is obtained owing to the fact that the driving means of the stamp is fitted with a cam roll or a suchlike means moving on the one hand :in a sliding means adjusted to the frame or to another iixed part and on the other hand in a sliding means adjusted to the stamp-carrier.
  • the pressure on the arti- -cle to be pressed carried out by the stamp-carrier will only be kept up during the desired time. If, however, one wishes to increase said pressure, the press may be so constructed that the roll, cam, or suchlike means consist of several parts and that the sliding means being con-r nected with the stamp-carrier is or are eccentric with regard to the other part or parts.
  • Figure 1 is a side elevation View partially in section showing a part of an embodiment of the invention.
  • Figure 2 shows a schematic section of the press according to Figure 1.
  • Figure 3 is a vertical view of a part of another embodiment of the invention seen to the right of the line IV-IV of Figure 4.
  • Figure 4 shows a section of this part of the press.
  • Figure 5 shows a vertical view of that part of the press seen to the left of the line IV--IV of Figure 4, and in which the connecting rod is in another position.
  • Figure 6 shows a detail
  • Figure 7 shows a part of another embodiment of the invention.
  • the press shown in Figures 1 and 2 comprises a driving rod I being rotary connected in 2 with the stamp-carrier which is not shown.
  • Said driving rod is provided with a slot 3 in which moves the crank pin II of the crank disc 6 saidl crank disc being driven by the shaft 5.
  • Said crank pin is provided with a sliding block 1 so as to reduce the losses due to friction.
  • the driv-l ing rod I is Aalso fitted with a roller 8 which moves in a slide I IJ fixed on the frame 9 serving as guiding means for the roller 8. During the motion of the. roller 8 inthe slide I0 the driving rod and the stamp-carrier are moved. It is clear that the slide IU may be fixed to the driving rod I and the roller 8 to the frame 9 while for driving the press one is not tied to crank driving means.
  • the frame IU is provided with a cam II against which the extremity I2 of a pawl I3 is pulled by a spring I4 xed at the extremity of this pawl.
  • This spring I4 is connected all? its other end With a movable point as for instance to a rod xed to the hub of the driving rod. This pull of the pawl takes place when the driving rod is in position II.
  • the other end I5 of this pawl I3 is hook-shaped and is hooked on over the hub I6 of the driving rod I or to another means connected with said driving rod.
  • the press Works as follows:
  • the driving rod I now moves from position II to position III. Owing to the fact that the bearing surface of the driving rod I and the pawl is eccentric with respect to the centre of rotation of the'driving rod I and the stamp-carrier the latter is still able to move a little.
  • the extremity I2 of the pawl I3 is shaped in such a manner that it rolls along the cam II whilst the end I5 of the pawl I3 rolls on the hub I6 of the driving rod I. This operation is performed simultaneouslyY with the rolling of the end I2 along the cam I I. Owing to this construction the pawl I3 in cooperation with the hub IB and the cam lI will exert an additional pressure which will be kept up during the movement of the driving rod from position II towards position III and vice versa.
  • roller 8 travels over a very long course during the opening and closing of the stamp.
  • the power required for opening and closing the stamp is very small the'losses due to friction will be very small.
  • the displacement of the cooperating guiding means with reference to each other is very small whilst the ypressure is kept up owing to this fact notwithstanding the great power used the losses due to friction will be small.
  • Figures 3, 4, 5 and 6 show a part of the second embodiment of the press according to the invention comprising cooperating guiding means consisting of a slide 20 in which moves a roller 2I the slide being adjusted to the frame or to any other fixed part and the roller to the driving rod.
  • Thispress is driven by vmeans of afshaftY 28 and' acrank disc 29 withrthe crank pin 430l or by any other known means.
  • the shaft 3 I need not necessarily be eccentrically connected and that the guiding means may also be of such a shape that the driving rod will be able'to ⁇ set" the stamp inmotion until the end of its course and' consequently that the guidingy means will keepthe stamp in place during a greater or lesser time during the stroke of the driving rod so as tokeep up the pressure for a time after the movement of the stamp being necessary to obtain the desired shape.
  • cam roller or other means 33 Fig. 'Y-to the driving rod said cam roller or other means will work on the one hand in a guiding means 34 being movably or not adjusted to the frame or to another xed part and on the other hand to a sliding means 35 adjusted to the stampcarrier.
  • the mobile parts of the means 33 which move in the guiding means may be separated owing to this fact one of these parts may be eccentrically connected with the driving rod. It will thus on the one hand be possible to decrease the friction and on the other hand to increase the pressure a little.
