MAX E. BIERSAOH, OF MILWAUKEE, WISCONSIN.

STAMPINGHMACHIN'E.

SPECIFICATION forming art of Letters Patent No. 632,548, dated September 5, 1899.

Application filed February 3,1899. Serial No. 704,370. (No modeli) To (.LZZ whom it may concern:

Be it known that I, MAX E. BIERSACH, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented new and useful Improvements in Stamping-Machines, of which the following is a specification.

My invention relates to improvements in stamping-niachines,and pertains especially to that class of stamping-machines illustrated in connection with my former application, Serial No. 662,170, filed December 16, 1897, for machines for making antitacks.

The object of my invention is to provide means for stamping or printing labels, with especial reference to that class of labels which are stamped or printed upon metal or other rigid surfaces.

In the following description reference is had to the accompanying drawings, in which- Figure 1 is a front View of my invention. Fig. 2 is a top view of the same. Fig. 3 is a sectional view drawn on line so a: of Fig. 1. Fig. 4 is a sectional view drawn on line y y of Fig. 1. Fig. 5 is an enlarged detail view drawn on line U U of Fig. 1. Fig. 6 is a rear View with the inking-pad and other parts removed to show the interior construction of the vertical reciprocating printing-head, and Fig. 7 is an enlarged detail view drawn on line T T of Fig. 6.

Like parts areidentified by the same reference-letters throughout the several views.

A bed-plate A is reciprocated horizontally underneath a vertically-reciprocating printing-head 13, the latter being actuated from the source of power by means of the belt 0, pulley G, eccentric D, adjustable connectinglink cl, and lever E. The motion of the printing-head is communicated to the bed-plate through the springs F, rack-bars F, pinions f, shafts f, gear-wheels G,and horizontal rackbars G. The printing-head is supported between and guided by the vertical posts H, and the die or printing plate I is supported underneath the head by means of rods 1, which extend upwardly through guide-apertures in the head, to which they are secured by means of springbuifers J. The object of the springs J is to permit sufiicient downward pressure to afiix the stamp and at the same time relieve the strain which would be experienced if the printing-die were secured rigidly to the head.

In order to supply the'ink to the die or printing plate I, I have provided an inkingroller K, which is actuated from the head B by means of the ears L, links L, ears M, crosshead M, lever N,and roller-supporting forked arm N. The cross-head M is'su'pported upon a rod 0, which connects'the supporting-posts H and forms afulcrum' for the lever N. The forked arm N is secured to the lever N by a hinged joint P and by a connecting-spring Q, so that the inking-roller K will pass yieldingly under the stamping-die I, one edge of which is curved upwardly so as to receive the inking-roller on its under side.

R is an inking-pad supported from the posts H by the arms S, cross-barT,and springcushion U. I It will be observed that as the printinghead B is moved upwardly its motion will be communicated through the connecting-links, cross-head, lever N, and forked arm N to force the inking-roller underneath the stamping-die I, while with'the reverse movement of the head B its movement will be communicated to swing, the inking-roller outwardly across the ink-pad R, from which it receives a fresh supply of ink.

The operation of my device is as follows: The material to be printed'upon is first placed upon the bed A, the printing-head B being then in its raised position, with the inkingroller K- underneath the die I. \Vith the downward movement of the head B the inking-roller is swung outwardly across the pad R, and the bed A is drawn inwardly underneath the head B and die I until it engages a stop V in the rear of the machine underneath the inking-pad R, the head 13 being permitted to continue its downward movement by reason of the springs F, interposed between the head and the upper ends of the rack-bars F. The continued downward movement of the head after the bed A is brought v in contact with the stop V brings the die I into forcible contact with the material upon the bed A, the springs J permitting the dieand the inking-rollerK is swung downwardly from the pad E into contact with the under surface of the die I. When the parts are in this position, the printed or stamped material may be removed from the bed A and fresh material substituted, whereupon the opera tion of the machine is repeated, as above described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination-of a vertically-reciprocating printing-head; a die connected therewith; a horizontally-reciprocating bed-plate; a stop for limiting the inward movement of the bed-plate; and connections whereby said bedplate is adapted to be actuated from the printing-head.

2. The combination of averticalIy-reciproeating printing-head; a die connected therewith; a horizontally-reciprocating bed-plate; a stop for limiting the inward movement of the bed-plate; and connections whereby said bed-plate is adapted to be actuated from the printing-head, said connections being provided witha yielding element adapted to permit the printing-head to continue its move.-

3. The combination of a vertically-reciproeating printing-head; a die yieldingly connected therewith; a horizontally-reciprocat= ing bed-plate; a stop for limiting the inward movement of the bed-plategand connections whereby said bed-plate is adapted to be actuated from the printing-head.

4. The-combination of a vertically-reciprocating printing-head; a die connected-there with; a horizontally-reciprocating bed-plate; a stop for limiting the inward movement of the bed-plate; connections wherebysaid bed= plate is adapted to be actuated from the printing-head; and an inking roller connected with,and actuated from, said head, and adapted to be swung alternately-into, and out of, contact with the surface of said die.

In testimony whereof I aiiix my signature in the presence of two witnesses.
