PUNCHING-PRESS.
SPECIFICATION forming part of Letters Patent No. 636,913, dated November 14, 1899.
Application filed May 11,1898. Serial No. 630,398. (No model.)
To aZZ whom it may concern:
Be it known that I, OTTMAR MERGENTHA- LER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Punching-Presses, of which the following is a specification.
My invention relates to punching-presses, and particularly to that form of punchingpress wherein the blanks are fed one by one in such manner as to be brought under the reciprocating die.
Although it will be understood that my improved machine is capable of general application wherever it may be desired to operate upon a series of blanks, it is shown and described herein as employed in connection with the manufacture of matrices for use in linotype-Inachines-such, forlexample, as those shown and described in Letters Patent of the United States Nos. 436,531 and 436,532, granted to me on the 16th day of September, 1890, as well as in a large number of other Letters Patent showing and describing linotype-machines invented by me.
My invention relates to the provision, in connection with the reciprocating plunger, of certain feeding and clamping devices which are employed to bring the blank to be operated upon into exact relation with the die and plunger and to firmly hold it in position While it is being operated upon thereby, and, further, in the provision of certain improved means applied to the plunger for holding the die securelyin position and whereby the plunger may be adapted to dies of difierent size.
My invention consists in the construction and combination of the parts hereinafter to be described in the specification and finally pointed out in the claims.
Referring to the drawings, Figure 1 is a par tial View, partly in section, of a punchingpress, showing my invention applied thereto.
justing-block. Fig. 5 is a perspective viewv showing a form of blank to be operated upon.
As illustrated in the drawings, I have shown my invention as applied to a form of punching-press particularly designed for punching the intaglio characters into blanks or matricessuch as that shown, for example, in Fig. 5. The blank X there shown is formed with the cut or recess X, wherein the'character is formed or sunk. I
The frame A of the press is or may be of any suitable construction, provided only that it possesses sufficient. strength and rigidity to sustain the operating parts and is formed with the platen or bed-plate B. Suitably journaled in brackets A on the frame A is the main shaft 0, to which power is imparted in the usual way by means of the band-wheel 0, fast thereon. Eccentrically journaled upon the shaft 0, as shown in dotted lines in Fig. 1, is the link C pivotally attached to the plunger 0 which is suitably guided in theguideway A It will be obvious that the rotation of the shaft 0 will effect the reciprocation of the plunger C in the manner well understood in the art. The triangular plate E is attached to the plunger 0 by means of the screws E E and between the plate E and the plunger 0 may be inserted the adjusting-piece E which may be employed to secure the proper vertical adjustment of the plate E and the die F, secured thereto. The plate E is formed with atriangular recess for the reception of the square die F, in which and partly surrounding the die F are placed the angular adjusting-blocks F F, which may be varied in size to accommodate dies F of different size. Also pivoted to the plate E at E is the retaining-arm E, which is secured in position by means of the pivoted bolt E, which enters a slot in the end of the pivoted arm E and rigidly holds the same. When in this position, the pivoted arm E impinges against the outer corner of the die F and firmly secures it in position. By the employment of the angular adj usting-bloeks F F of different size and of the pivoted fastening-arm E it will be apparent that I am enabled to employ dies of different size and to secure them in proper position, and, further, that a change of dies may be readilyeifected.
ICE)
Suitably supported upon the platen B is the block D, which has secured to it the guiding-plate D formed with an aperture through which the die F passes in the downward reciprocation of the plunger. The plate D is horizontally adjustable on the platen B by means of the wedge-shaped adjusting-pieces D D, which are inserted at the end of the plate D and between it and the platen B of the press. The plate D is further provided at its two sides with brackets K, provided with the springs 1 K between which and the brackets K may be inserted plates K K of proper thickness to secure the accurate guiding and holding of the blanks operated upon, which are advanced between them under the descending die.
The platen B is formed'with the recess B, through which the blank drops after it has been acted upon and is retracted from under the die. Also guided upon the platen B is the reciprocating slide G, which is formed with ears J J, within which the blank to be punched is placed and held in position to be advanced under the die. The necessary reciprocating motion is imparted to the slide G by means of the lever G pivoted to the frame of the machine, which abuts against the end of the slide G and at the proper time causes its forward movement. The rearward movement of the plate G is effected by the connection of the plate to the pivoted lever G by the spring G, which provides a yielding connection for the retraction of the plate G. Resting upon the inner end of the pivoted lever G is the hollow rod or sleeve G within which the plunger G is contained, the spring G being inserted between the plunger G and the bottom of the sleeve G to afford the neoessaryyielding connection. The arm G pivoted to the bracket A on the frame A,-as shown in dotted lines in Fig. 3, rests upon and imparts motion to the plunger G and thereby through the yielding connection G to the sleeve G and the lever G The spring S, attached to the frame A and to the pivoted lever G tends to raise the said lever and to keep the various connected parts in their uppermost positions. This action of the spring S is, however, resisted and controlled by the cam G on the shaft 0, which acts upon the pivoted arm G in such manner as to effect the necessary operation of the lever G at the proper times. The cam G is so shaped and timed as to effect in proper sequence, first, the complete inward movement of the slide G to bring the blank under the die; second, the outward movement of the slide G to a position where the blank X will be dropped through the recess B in the platen B, and, third, a partial inward movement of the slide G to such position that the ears J will be carried out of registration with the recess B and a fresh blank may be inserted between the said ears in readiness to be advanced under the die.
Having described the construction and areac,913
rangement of the various parts of the machine, its operation will be understood to proceed in the following manner: The blockD and the plate E are suitably adjusted in the desired positions by means of the parts previously described. The proper die or punch F is inserted in the plate E by means of the necessary angle-blocks F and firmly secured in position by means of the retaining-armE. The parts being in the positions indicated in full lines in Fig. 1, a blank or matrixis placed within the ears J in front of the slide G and resting on the platen B. Motion having been imparted to the machine, it will follow that the rotation of the cam G acting upon the arm G and therefrom, through the yielding connection previously described, on the pivoted lever G will effect the turning of the lever G about its pivot and the consequent advancement of the slide G to its extreme inward position, thereby bringing the blank X in position to be acted upon by the die F. It will be seen that the ears J on the slide G are so located thereon that they pass over and above the plate D, thereby permitting the blank X to be advanced closely and accurately against the block D and to be firmly held there during the subsequent operation of the punch or die. The plates K K, which have been previouslyinserted and are of the proper thickness, limit the inward movement of the slide G. This position of the parts is that indicated in Fig. 2, wherein the punch or die is shown as in engagement with the blank. After the die F has acted upon the blankX and has been freed therefrom by the upward movement of the plunger the slide G is retracted to its extreme outward position by the further action of the cam G and the spring S until the parts assume the position shown in dotted lines in Fig. 1. The rearward movement of the slide G, by reason of the engagement of the ears J with the blank X, has retracted the blank until it is brought over the recess B, formed in the platen B, through which it drops, and is thereby freed from the ears J J. The further action of the cam G then causes the parts to return to the positions indicated by full lines in Fig. 1, wherein the slide G is shown as having passed over the recess B, permitting the introduction of a second blank or matrix within the ears J in front of the slide G and resting upon the platen B. The operation then proceeds as before.
Although I have shown and described my invention as applied to a preferred form of punching-press, it will be understood that many changes and substitutions may be made therein without departing from the spirit of my invention.
Having described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a punching-press, the combination with the plunger and die, of the angular adjusting-pieces and the clamp for adjusting and holding the die respectively, substanthe plunger having an angular recess, detach able adj usting-pieces fitting said recess, and a clamp arranged to hold'the die against said adj listing-pieces, substantially as described.
3. In a punching-press, the combination with the reciprocating plunger and die, of a platen, an adjustable gage-plate upon the platen, a feed-slide, devices for holding the blank in relation to the feed-slide, and means for moving the slide and blank yieldingly to the gageplate and returning said slide and blank after the blank is punched, substantially as described.
4. In a punching-press, the combination with the plunger, the angular adjustingpieces, and the clamp for holding the die against said adjusting-pieces, of the adjustable block D, the gage-plates K, and the slide G movable against saidgage-plates, for the purpose described.
5. In a punching-press, the combination with the plunger and die, of a platen having an opening through which the blanks may fall, a slide movable upon the platen to carry the blank from the die to said opening, and a cam and connections for moving said slide to carrythe blank, first to the die, then to the discharge-opening, and then to an intermediate position at which a new blank may be received.
6. In a punching-press, the combination with the plunger and die, of the slide for carrying a blank, a lever for moving said slide, a spring connection between said slide and lever, a cam for operating said lever, and a spring connection between said cam and lever, Wherebythe slide is moved yieldinglyin both directions.
In testimony whereof I affix my signature in presence of two witnesses.
