PUNCH.
SPECIFICATION forming part of Letters Patent No. 395,342, dated January 1, 1889.
Y Application filed July 19, 1888l Serial No. 280,441. (No model.)
To @ZZ whom t may concern: A
Be it known that I, STEBHEN T. NAKASH- JIAN, residing in Boston, in the State of Massachusetts, formerly a resident of Harpool, Turkey, and a subject of the Sultan, have invented a new and useful Improvement in Punches, of which I, the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of t-his specification, in explaining its nature.
The invention relates to a punching implement having the specific construction hereinafter specified.
Referring to the drawings, Figure 1 is a view of my hand punching-toohfone of the side plates of the device being removed to better illustrate the construction. Fig. 2 is a view in section upon the dotted line of Eig.'
1. Fig. 3 is a view in plan of the punchlever from its under side. Figli is a view of one of the side plates. Eig. 5 is a view of the gage. Fig. 6 is a view illustratinga slight modification in the form and manner of attaclnnent of the gage to the die-head. v
The implement is represented as provided with a punch and die suitable for cutting or punching from thin sheet metal or other material V or triangular shaped pieces; but I would here say that the punch and die may have any desired configuration other than a triangular shape.
The implement comprises the punch-lever A and the die-lever B, each of which levers is pivoted at a l), respectively, to the side plates, a b', and the operating levers or handles O O, pivoted to said side plates at c c', respectively, and preferably geared or connected together at their pivot-points by the segmental gears c2 c3, and having extensions c4 c5, the rst of which extends to come in contact with the inner surface of the end of the punch-lever, and the other of which extends to come in contact with the inner surface of the end of the die-lever. y
In addition, the implement has the opening-sprin g A2, placed between the punch-lever and the die-lever, to automatically separate the punch and die, and the adjustable gage D, attached to the die-lever. The punch-lever has the head a2, which has the extension a3,
forming the punch, and which is integral with the head. It also has the arm afl, which is also integral with the head. The die-lever has the head b2, the upper surface of which is level or plain, and the sides of which are parallel, and through which is a die-recess, b3, extending from the upper surface through the `block and gradually enlarged from the upper surface. This head h2 has integral with it the arm b4. There is attached to the dielever a gage, D, preferably having two arms, d, which extend above the upper surface, b4, of the die-block, and are made adjustable lengthwise the same, preferably by means of the slot d in the cross-section or part which unites the two arms of the guide, and a set-screw, d'2, which screws into the lever. By loosening the set-screw the gages may be simultaneously moved or adjusted to bear any desired relation to the die and punch. In lieu of this method of securing the gage to the die, that represented in Eig.
6 may be employed, where each arm of the gage is represented as having a long slot through which passes a set-screw entering the side of the die-head.
It will -be seen that by pivoting the punch and die levers as specified and shaping the surface of the punch and die-block as shown and described the punch has a shearing movement in relation to the die, which is a very great advantage in the operation of the tool. The advantages of the invention arise from the simplicity and cheapness of the construction. c
I would say that I do not confine myself to the particular form of handles or levers for operating the punch-lever and the die-lever.
Having thu s fully described my inventioml claim and desire to secure by Letters Patent -of the United Statesl. The punching implement herein described, the same comprising the punch-lever A, having the head a? and punch cf' integral therewith, the die-lever l, having the dieblock b2 integral therewith, provided with a fiat surface, and a die-recess, b3, extending from said surface ,through the block, the side plates, a b, the lever-pivots a l), the operating-arms C O',
IOO
having the extensions c4 c5, to `operate the punch and die levers, respectively,
the pivots c c', and the spring tially as described.
The punching implement herein described, the same comprisingthe lnnieh-lever A, having' the head a2 and punch a integral therewith, the die-lever l, having' the die- AQ, Substanbloek b2 integral therewith, provided with a i 3. In a hand punching' implement, the
punch-lever A, having the head and punch u* integral therewith,
and arm c, in. combination with the de-lever ll, having' the dicbloek h2 fiat integral therewith, provided with a surface, a die-recess, b3, extending from said surface through the block, and the arm b", substantially as described STEPHEN l`. NAKASHJIAN.
