AUTOMATIC RAZOR BLADE ETCHING MACHINE Filed July 14, 1932 3 Sheets-Sheet 3 Patented Mar. 20, 1934 lesione i AUTOMATIC RAZR BLADE ETCHING MACHINE In Germany Claims.
The present invention relates to a razor blade etching machine of the automatic type, in which the rubber stamps serving for stamping the blade on both sides are actuated by lifting and pressure 5V devices.
.1n the known machines of this class the etched blades drop out of the machine immediately after being stamped, and it often happens that the etchingr becomes blurred because it is not given 1:15). time to dry. Further drawbacks connected with machines of the existing type are due to the employment of a rubber-covered bow or disc for removing the blades from their magazine, and the invention. proposes'ito eliminate all these draw- 415a backs by providing that the blades are taken one by one out of the magazine by a suction device capable ofmoving up and down, are stripped oif during the ascent of the. suction device by the stop plate of a slide, anddrop from the latter 2Q4v into shaft-like guides on a horizontal disc to which a Maltese cross is xed which is rotated by means of a crank pin secured to a cogwheel in, order to intermittently rotate the disc a certainextent, such as one-eighth of the revolution, so that, for example, the blade after being inserted in one of the shafts is etched in the known manner by the twostamps during the first partial rotation of the disc and drops out of the shaft opening only after the disc has made a certain number of partial revolutions, e. g. three-eighths. One form of the invention is illustrated in the accompanying drawings, in which Figure 1 is a view of the machine according to the invention and of the suction device and the disc conducting the blades to the stamps; Fig. 2, a top view of the machine; Fig. 3, a side View seen from A; Fig. 4, a side view seen from B; and Fig. 5, a rear View of the machine.
Referring to the drawings, the blades 1 are lstamped in the withdrawable magazine 2. The magazine plate 3 has a surface which is inclined to wards the inside of the machine and is connected with a screw 4 by means of which it is controlled and which carries a ratchet wheel 5 turned by the ratchet 6. The lever of the ratchet 6 is secured to a double slide 7 which can be reciprocated by a connecting rod 8 articulated with its other end to a crank pin 10 secured to the cogwheel 9. The cogwheel 9 is secured to the shaft 11 and is 5.0 'driven by the gear 12 disposed on a shaft 13 in the machine frame. The blades are taken out of the magazine 2 one by one by a suction device 14 secured to the shaft 15 at the other end of which a bevel wheel 16 is provided which engages a 5 5 'bevel wheel 17 on the shaft 18. To the other end April 19, 1932 (Cl. lill-44) of the shaft 18 a lever 19 is secured which by means of a cam 2G and a rod 21 rotates slightly over 99 at each rotation of the cam 29.
The cam 29 is secured to a shaft 13 driven from Y the main shaft 26 by means of the two sprocketsA 23, 24 and the chain'25, the main shaft 26 being driven by the pulley 27 and a motor or connecting gear, not shown. The advancing and returning motion of the shaft 18 and the lever 19 is transmitted to the suction device 14 which is thus moved 96 up and down. The suction device 14 is connected by a piping 28 with a vacuum pump, not shown. At each descent of the suction device one blade is taken out of the magazine 2 and stripped off again, during the ascent of the device, by a plate 29 having an opening through which the suction device 14 may pass to complete its upward motion.
The blade after being stripped off by the plate 29 slides into the chute 30 and then drops into one of the shaft-like guides 31 to 38 which are disposed in the horizontal disc 39. On the other end of the shaft 13 to which the cam 29 is secured the gear wheel 12 is provided which a ,crank pin 41 is secured which engages the Maltese cross 42 rigidly connected withthe disc 9. The Maltese cross 42 intermittently turns the disc 39 and has eight arms, so that every time a blade Y drops into the disc shaft under the chute 30 the disc 39 will be turned one-eighth of a revolution in the direction of the arrow. The etching of the blades takes place, as soon as the disc has completed the first eighth of a revolution, in the known manner by means of the two stamps 43, 44 which are moistened by the pad 45 lying between them. The two stamps 43, 44 are provided on their short Shanks with the rolls 46, 47 and are moved by the eccentric 48 so as to be placed over the blades in the shafts. After the first eighth of the intermittent motion of the disc 39 has been completed the rolls 49, 50 engage deep cavities in the eccentrics 51, 52, the rolls 49, 50 being positively controlled by springs in the bushes 53, 54. Simultaneously with the rolls 49, 50 move also the forks 55, 56 to which the rolls are secured as well as the stamp levers 43, 44 which with the forks 55, 56 are disposed on the joint shafts 57, 58, and the centric motion carried out by these elements towards one another brings about the stamping of the blades.
