April 18, 1939. H. P. PALLESEN SELF-INKING STAMPING MACHINE FOR LINED OR THE LIKE Filed Sept. 14, 1956 Patented Apr. 18, 1939 UNITED STATES FTENT OFFICE SELF-INKING STAIVIPING MACHINE FOR LINEN OR THE LIKE 2 Claims.

This invention relates to a self-inking stamping machine for marking linen or the like, including an inking device mounted on a lever for the stamping head composed of type wheels and a 5 rigid abutment influencing the lever of the inking device. In known machines of this kind the lever of the inking device is influenced in one direction by a weight and in the other direction by a spring. This does not ensure either uni- 10 form inking or the removal of the inking pad from the type.

According to the invention, these defects are eliminated by the fact that carrier lever of the inking device is in the form of a bell crank 15 lever and is provided with two notches in the range of its contact with the fixed abutment, one of which serves to cause the inking pad to making temporary contact with the type when the stamping head moves downwards, while the 20 other serves to locate the inking device when the stamping head moves upwards in a position of rest, in which the device is removed from said stamping head.

One embodiment of the invention is illustrated by way of example in the accompanying drawing,

wherein:

Fig. 1 is a side elevation of the machine with the self-inking device,

Fig. 2 shows the notched lever of the inking 30 device in side elevation.

Fig. 3 shows the notched lever of the inking device in front elevation.

Mounted on the base plate a there are two bearing uprights b carrying the shaft d of a two 35 armed rockable lever c. On one arm of the lever c is mounted the stamping head 6 with type wheels 9 rotatable on the removable pin f.

The self-inking inking device h is rotatably mounted laterally on the lever c. It substan- 40 tially comprises a rockable lever with an abutment arm I and an arm carrying the stamp pad container m. In the vicinity of the point Where the two arms meet two notches 2' and k are formed.

45 Disposed on the base plate a there is an abutment n with rubber buffer 121 for the lever arm 0.

In order to cause the lever c to return into its position of rest after each stamping operation, a connecting member with a projection 01 is 50 disposed at the free end of lever 0. One end of a spring p is attached to said projection and the other end thereof is anchored in an eye p1 of the base plate a.

Disposed on the base plate a under the stamp-' 55 ing head e there is an anvil q with a rubber pad (11, on which pieces of linen are placed during the stamping operation to receive the blow of the marking types.

The lever c is provided on its arm carrying the stamping head e with a connecting piece 1' having a projection 11 to which is pivotally attached a vertical pullrod s. This rod .9 is extended downwardly by means of a chain s1 and is passed through the base plate and the top of the table on which the machine is mounted, and at its lower end it is connected to a pedal s2 whereby the downward movement of the stamping head e is eifected during the stamping operation.

Mounted on the lever 0 there are two extension pieces 15 with a connecting piece 151, disposed there- 15 between. Secured to this connecting piece h, as by screws or otherwise, there are one or more springs 132, with arresting projections for the type wheels.

Fixed to the bearing standard I) there is an arm a which carries a rotatable roller 11 serving as an abutment for the inking device h. In the upper position of rest of the stamping head ,e the roller 21 is in the lower notch i.

The operation of the self-inking inking device 25 h during the stamping operation is as follows:- When the stamping head e is caused to move downwards by treading on the pedal 82, the roller 1) is forced out of the notch 11 and caused to engage in the notch 70. The stamp pad container m is thereby pressed on to the type wheels and performs the inking thereof. During the further downward movement the lever arm I is applied to the roller 1) and is moved upwardly thereby, the stamping pad container m being positively moved from within the range of the piece of linen to be stamped. When the pedal s2 is released the stamping head e and the inking device h automatically return into their position of rest. The roller 12 automatically engages the notch i and prevents the stamping pad container m from being applied to the type wheels. It is to be noted that between the notches k and i there is left a projection k and it is this element which temporarily moves the pad container m into en- 5 gagement with the type wheels during the movements of the lever arm Z.

I claim:

l. A self-inking stamping machine comprising in combination a printing anvil, a stamping head movable toward and from the anvil, an abutment fixed relative to the anvil, a bell crank lever pivoted relative to the head and movable bodily therewith, an inking pad positioned laterally of the lower end of the bell crank lever, said bell crank lever being provided with spaced notches and a projection therebetween, the lowermost of said notches being normally engageable with the abutment to normally maintain the inking pad spaced slightly from the stamping head while the projection during downward movement of the head coacts with the abutment to temporarily press the inking pad against the head while continued downward movement causes the second notch to engage the abutment and efiect swinging of the bell crank lever to move the inking pad to a position remote from the stamping head.

2. A self-inking and stamping machine comprising in combination, a printing anvil, a stamping head movable toward and from the anvil, an abutment fixed relative to the anvil, an inking device including a bell crank lever freely suspended from the head and movable therewith, an inking pad carried laterally of the lower end there,- of and the rear face of the lever being provided with contact means for coacting with the abutment during the movement of the stamping head to first move the pad into inking engagement with the stamping head, and then swinging the lever to maintain the pad in the position remote from the head to permit the latter to engage with the printing anvil.
