Stamp machine with swinging type carrier.

Patented in the German Empire on March 21, 1906.

The invention relates to stamping machines with a vibrating type carrier and is that in such a stamping machine the type carrier by means of a him with forked end encompassing two-armed lever alternately vibrating. different size. is displaced, while at the same time by the drive shaft of the type carrier the linearly displaceable ink pad holder ίο is given a back and forth movement, that the type carrier first with the ink pad and then with the underneath it arranged printing table comes into contact.

In the drawing, the stamp machine is shown, namely Fig. 1 shows the machine in plan view and illustrates the device for engaging and disengaging the ink pad in and out of the path of the type carrier. Fig. 2 shows the machine in side view, partially in section, and illustrates the connection of the ink pad holder to the machine and the drive device for the ink pad holder.

FIG. 3 shows the left end of the machine in FIG. 1 in elevation.

Fig. 4 illustrates the device for

Swinging of the type carrier in side view.

Fig. 5 illustrates, partly in section

and partly in elevation, the means for adjustably mounting the paint pad in its Holder.

The type carrier c ¹ is driven in the following way:

As can be seen from FIG. 1, the arm c ^{4 of} the type carrier c ¹ engages rollers d ¹⁰ , which are seated on pins d ¹ arranged on a lever d. This lever d engages by means of a roller d ² in a thumb groove e ^{1 of} a groove disk β . As can be seen from Fig. 4, is

the groove e ^{1 of} the disc e with two book , 2

40

lines e ² and e ³ provided which, when the disc e is rotated, give the lever d and, by means of the pins d ¹ and rollers d ^10, the arms c ^{4 of} the type carrier c ¹ an oscillating movement. The indentation e ^{2 of} the thumb groove e ¹ brings the type carrier c ¹ into engagement with the ink pad g and back into its normal position, so that the ink pad g can be removed from its path. The indentation e ³ then swings the type carrier further down onto a table h and the object lying on it, in order to print the latter.

The color pad g, which is used to provide the types of wheels c ^{2 of} the type carrier c ¹ with color before they come into contact with an object placed on the table h , consists of a piece of felt g ¹ or other absorbent material, which is placed in a box g ² . As can be seen from FIGS. 1 and 2, the box g ^{2 is carried} by a holder or bracket g ³ , which can slide parallel to the oscillating shaft b of the type carrier in a slot a ^e provided in the frame a ¹ . The box g ² carrying the actual ink pad g ¹ is supported by adjusting screws g ⁸ in the bracket g ³ and is clamped on the same by a rod g *, the rods g ^{6 of} which slide in sleeves g ⁶ on the underside of the bracket g ³ and in the same can be attached by clamping screws g ⁷ (Fig. 2). The box g ² can be set at different angles using the adjusting screws "g ⁸

Positions in the bracket g ^{s are} held and raised and lowered. As a result of this adjustment of the box g ² , the ink pad g ¹ can be brought into the appropriate position when the amount of movement of the type carrier c ¹ is increased or decreased depending on the setting of the pivot point of the lever d.

The device for the rectilinear movement of the ink pad g ¹ to the type carrier c ¹ and

ίο away therefrom is the following:

On the shaft ⁴ of the cam face e e is fixed a thumb disk k, the two Vorspränge k ¹ and k ² has. These come into engagement alternately with a segment k ³ , so that an oscillating movement is imparted to a ^{shaft Ä 4 connected to it.} The movement of the shaft k ^l is transmitted to the bracket g ^{3 of} the ink pad by means of an arm k ⁵ and a rod k ⁶ , and the latter is accordingly alternately fed to and removed from ^{the type carrier c 1.} If the ink pad is below the type carrier, it is brought into engagement with the ink pad ^{through the indentation e 2 of} the thumb groove e ^{1 of} the disk e ^{and its type wheels c 2} 'are provided with color. As soon as this has happened, the type carrier is ^{returned to its normal position through the bulge of the thumb groove e 1} and the ink pad is then withdrawn into the position illustrated in FIGS. 1 and 2. If the indentation e ^{3 of} the groove e ¹ then engages with the roller d ^{2 of} the lever d , it swings the type carrier c ¹ downwards onto the table h and brings the stamp wheels c ² into contact with the object lying thereon. ■■ /, '' ■■. ^Λ

Claims (1)

Patent claim: , Stamp machine with oscillating type carrier, • characterized in that the type carrier (c ¹ ) is alternately set in vibrations of different magnitudes by means of a two-armed lever (d) which encircles it with a forked end, while at the same time the drive shaft (e ^l ) ■ of the type carrier the rectilinearly displaceable ink pad holder (g ^z ) is given a back and forth movement in such a way that the type carrier first comes into contact with the ink pad and then with the printing table arranged below it. 1 sheet of drawings.
