to the accompanying drawings, and to let-V ters or figures of lreference marked thereon, which form a part of this specilication.
The present invention has for its object a hand-printing stamp for stamping different inscriptions, such as addresses on envelope, papers, etc. The main feature of the invention consists in the combination with a spring actuated vertically movable stamp, the lower end of which carries an inking pad; of a pattern band, providedl with perforations, corresponding to the several 1nscriptions, said pattern band being given a stepwise motion by each movement of the stamp.
On the drawing is illustrated a form of the invention.
Figure 1 is a section on line I-I of Fig. 2, and Fig. 2 is a side view of the same.
The vertically movable stamp 1 with an ink pad is kept in place by means of a spring 2 and is slidably mounted 1n frame 3. Said frame 3 also carries ratchet wheels 4;, gears 5, 6, toothed segments 7, guiding rollers 8 for guiding pattern band 9, drums 10 which are connected with ratchet wheels 11 and gears .12. The frame 3 is yieldingly mounted in frame 13, by means of bolts 14, 15 and is kept in position by means of springs 16. On frame 13 is mounted the double pawl 17 engaging the ratchet wheels 1 and bolt 19 ifor driving toothed segments 7.
The bolt 19 is slidably mounted in bore 21 in frame 13. A spring 23 tends to pull the bolt out of its operative position in which it is maintained by means of a pin lock or the like not shown. Two bores 21 are provided, and the bolt 19 may be placed in either of them so as to cooperate with either the left hand or right hand toothed segment 7. The drums 10 are loosely mounted on shafts 24C journaled in frame 3, and are each eonnected to its shaft by a spring 20, one end of which is secured to the drum and its Vof the inking pad.
other end secured to the shaft. The ratchet wheels 11 and gear wheels 12 are secured to the shafts 24 and the ratchet wheels 11 are adapted tobe engaged by pawls 22 mounted on the drums 10, so as to prevent backward rotation of the drum with respect to the shaft when the band is wound on the drum, while it does not connect the drum and ratchet wheel when the band is wound,
off the'said drum. The apparatus manner:
When stamp 1 is pressed downward, frame 3 will band 9 is pressed against any object placed beneath, such as a paper, a letter or the like. The pattern stamped in the pattern band will be printed through the same by means During said movement of frame 3, bolt 19 acts to rotate one of the toothed segments 7 according to which bore 21 the bolt 19 is in, and the shaft 24 rotated, thus tightening spring 20. At the same time operates in the following pawl 17 passes along ratchet wheel 4 into a position, in which it engages the next tooth. When the pressure on stamp 1 ceases, the said stamp and frame 8 will be carried back to their original position by means of springs 2 and 16. It is to be understood that the spring 2 which operates the stamp is stronger than the springs which operate the movable frame.
During the upward movement pawl 17 will rotate ratchet wheel 4 and gear 5 connected therewith, and said gear will again rotateV gears 6, mounted on. rollers 8. Hereby the pattern band is moved one step, being wound off the left drum 10` and upon right drum 1() by means of spring 20. By each pressure on the stamp the said operation will take place, the band being wound ofi' one drum on to the other, one address or inscription being stamped for each pressure.
The direction of movement of the pattern band may be altered by swinging the double pawl 17 toward the left, so that its right tooth engages ratchet wheel 4. Bolt 19 is removed 'from its position and placed in hole 21, engaging toothed segment 7 on the left hand side. Further pawl 22 is brought out of engagement with ratchet wheel 11 on the right hand side, pawl 22 on the left hand side being simultaneously brought into engagement.
The drums may also be so mounted that also be pressed down, so that they may be changed, so that a number of drums with different pattern bands may be used.
Claims: Y 1. In handprinting stamps the combination with a vertically movable spring actuated stamp, provided with an inking pad .at its lower end; of a pattern band, provided with perforations, correspondin to the sev'- eral inscriptions or addresses to e stamped, said pattern band being given a stepwise motion by the reciprocating movement of the stamp.
2. In handprinting stamps the combination of a vertically movable spring actuated stamp, carrying an inking pad at its lower wheels with oppositely directed teeth, a
double pawl, mounted on the stationary frame cooperating therewith for rotating the pattern band drums in one or the other direction, a spring actuated stamp slidably Y' mounted in the movable Jframe, the tension of the spring acting on said stamp being stronger than the tension of the springs acting on the movable franrle.-
4. In a hand printing stamp, a stationary frame, va spring pressed stamp, band carrying spring drums, guide rollers for the band, pinions `on the guide rollers, a gear wheel meshing with the pinions, a sliding and tionary frame and carrying said'mechanism,
and mechanism for putting the springs of the drums under tension during the operation of stamping. f Y Y 5. In a hand stamp,a stationary frame, a. sliding and spring pressed frame mounted on the stationary frame, a shaft mounted in v'che siiding frame, and carrying a pinion and ratchet wheel, a spring drum loose on'the shaft, a pawl on the drum for engaging the ratchet, a toothed segment on the sliding frame and eng-aging theppinion of the said,
shaft, and lstops on the stationary framerfor operating` the segment when the sliding flame is depressed. l l 1 In testimony that I claimthe foregoing l as my invention, I have signed my naineY in presence of two subscribing witnesses.A
