PANNIER, OF'KILBUCK TOWN SHIE, ALLEGHENY COUNTY, PENNSYLVl-ZN 1A.,ASSIGNOR TO PANNIER BROTH- ERS STAMP COMPANY, OE PITTSBURGH, PENNSYLVANIA, A CORPORATION OI PENNSYLVANIA EMBOSSING MACHINE Application filed March 26, 1229. Serial No. 350,956.

Our invention consistsof an'improvement in embossing machines for metallictags or the like. It has in view to provide in eans'for stamping or embossing a strip of thin metal or other suitable material by means ofa plurality 03E movable stamping'elements capable of being adjusted to various combinations in a simple, expeditious and efficient manner.

In general, the machine comprises a series of pairs of spaced apart stamping bars, each pair being longitudinally adjustable across the path of a transversely movable blank, with means for locating and holding the bars in position means for temporarily holding the blank in place, means effecting operative closureand opening of the bars, and various other features of construction and operation, as shall be more fully hereinafter described. 1 v. j j

Referring to the drawings showing one preferred embodiment of the invention:

Fig. 1 is a vertical sectional view on the line I-I of Fig.3, partly broken away;

Fi g. 2 is a cross section on the line 11-11 Fig. 3 is a plan View of the machine show ing a strip passing therethrough, 1

v Fig. 4 is a detail view in perspective of the adjusting tool for the stamping bars j I Fig. 5 is a horizontal sectional detailview showing the temporary holding means for the blank. r I p I Referring. to the drawings, the mach ne is provided with a base 2 01. any suitable construction adapted to bemounted on thefioor, extending upwardly in the manner of a pier, and providing at its upperend a supporting top or plate 8.

A supporting base .4 is mounted on top plate 3 and secured thereto by any suitable means, such base: extending laterally each side, in the general direction of the stamping bars, and providing ample longitudinal support therefor v p I The upper surface of base 4 is planed smooth, providing a flat supporting-surface for the bottom edge of the lower membera of the series of two-part stamping bars a and 1 I Such bars, 'as shown, are .providedwith male and female stamping elements 0 and d respectively, between which the longitudinal strip or blank 5 is passed, for operation thereon by the stamping bars.

As shown in Fig. 3, the sets of bars are assembled side-by-side, of varying widths.de-

pendent on their stamping characters, and so arranged that each individual set may be adjusted longitudinally, to bring the particular pair of stamping or type elements 0 and d intomiddle position across the path of movement of blank 5.

v For such purpose both members a and b are connected together in any suitable manner as by means of interfitting pins 6 at each end,

operatingto hold the two parts in registeringpositionandpermitting the lower bar a to be thrust upwardly toward the upper bar 6 and against the separating springs 7, surrounding'the guide pins 6, as in Fig. 1.

in upper bridge piece 8 extends across the top of the machine and provides a limiting bearing for the upper edge of each bar b to resist the stamping pressure when its companion lower, bar is raised towards it. Upper bar 6 is provided with a series of notches 9 corresponding with the transverse center line and spacing'of each pair of abutments c and d. 1

Automatic holdingpins 10 are mounted upwardly within the bridge 8 having blunt I vsshaped terminals at their lower ends and bearing against a'spring 1.1 in the hollow upper portion of pinslO, with limiting shoulders 12 engaging a shouldered plate or the like. By such means the pair of bars ab when moved longitudinally in either direction, will be held for operation at the particular position desired, it being understood that each bar is so provided. I

For the purpose of indicating to the operator the position of any particular pair of stampingabutments cd, when in proper registering position with the blank,'the upper edge portions or" bar 6 are identified by iii marking, as by numerals orletters e, corredicating marking being located just beyond the bridge 8 when in such position. In

other words, the marking positions are longitudinally oif-set for visibility and are exposed just beyond the edge of the bridge at the time when the corresponding stamping elements are in middle registering position, as .in Fig. 1.

Each pair of stamping bars a-b is adjusted longitudinally in one direction or the other to bring the proper marking or stamping :ibutn'ients into register with the blank by means of a suitabletool 13 having a comparativcly narrow terminal provided with a hole 14 for engagement of the extended end 15 of one of the pins (3. Otherwise, the pin 15 may be grasped by the lingers and may, if desired, be flattened to provide a grasping terminal.

By such means any particular pair of stamping bars may be moved longitudinally in either direction over the smooth upper surface of base 4 and adjusted to proper position for operation, when they will. then be held by the automatically operating blunt wedges or points 10.

Blank 5, which may be fed from a reel in convenient location for such purpose, is provided at suitable intervals with edge notches 16, by which in the same manner the blank may be engaged and temporarily held by similar blunt pointed spring pressed pins 17 one at each side of the blank. Such pins are mounted in suitable receiving bearings 18 on the frame or its bridge, the pins being normally extended by reacting springs 19, as clearly shown in Fig. 5.

The blank 5 being previously provided with notches 16 and securing holes 20, may after stamping be reversely folded at the location of each pair of notches 16, facilitating its separation by bending into individual tags after being QF'IbOSSGd, as is well understood in the art. At the opposite side of the machine it is provided with a comparatively narrow guiding slot 21 below a cover plate 22 of supporting abutment 23, by which the blank 5 may be introduced and guided through the machine, and between the members of the several series of stamping bars (lfb.

As thus arranged it will be seen that with a series of pairs of such bars, each provided with its individual longitudinal series of letters, numerals, or other desired or useful in dicia, each pair of the several pairs of bars may be adjusted in one direction or another, to bring the desired or particular pair of stamping abutments into transverse register with the other selected stamping elements of other-pairs, for any number or the complete series thereof, as indicated in Fig. 3.

When thus adjusted the blank may be passed intermittently through the machine so, that when all of the lower bars a are raised together against resisting bars I), the com plete unitary portion of the strip will be stamped, after which the next section between grooves 16 may be advanced and the operation repeated.

For the purpose of thus raising all of the series of lower stamping bars a against bars at the same time, means are provided for elevating the bars at'the middle and also at each opposite end.

At the middle position, corresponding to the zone of pressure on the blank, a lifting gudgeon or block 24 is mounted for vertical movement in a socket 25 of base 4 for sliding movement therein. Plate 3 of the frame is provided with a registering clearance opening 26, and gudgeon 24 is proivded with a downwardly extending bearing terminal 27 projecting therethrough.

Pivotally mounted on cross shaft or pin 23 carried by lugs 29 of plate 3 is the upper end 30 of the main operating lever 31. The upper face of head 30 of the lever is provided with a curved bearing surface 32, eccentrically developed with relation to the center of pivoting bearing pin 28, by ofi-setting such pin mounting, in the manner shown in Fig. 1, The lower end of lever 31 is provided with a treadle extension 33 extending forwardly toward the front opening 34 of base 2, whereby the operator may thrust lever 31 backwardly by such treadle engagement.

For the purpose of providing corresponding upward movement for the end portions of the lower bars a, or of one end portion or the other, dependent on the shifted position of said bars, we provide a pair of eccentrically mounted rollers 35. These, as shown, are pivotall carried by pins 36 and are mounted across t e end portions of the base 4 in suitable clearance openings 37, so that when such rollers are operated together simultaneously with the movement of arm 31, they will effect lifting action on bars a to the same extent as that effected by the cam action of curved face 32.

For such purpose rollers are provided with lever arms 38 pivotally connected at 39 by links 40 with the main arm 31, as at 41. When arm 31 is thrust in by treadle engagement, the lifting action of all of said elements will be simultaneously effected, and the stamping operation accomplished, lever 31 returning to its normal position by gravity upon removal of foot pressure, and opening the stamping bars for feeding adjustment of the blank preceding the next operation.

It will be understood of course that any selected sets of stamping bars may be removed and others substituted, for various combinations of marking elements. The several bars may be of varying thickness either in. multiples of minimum width bars or otherwise, it not being necessary to register exactly with the holding pins 10, as such pins will operate by engaging one bar only or on two adjacent bars.

The construction of the machine andits manner of operation will be readily understood and appreciated from the foregoing description. It providessim-ple, efiicient and continuously operative means for effecting the stamping of a strip of'metal or the like sectionally, and of providing for an extremely wide range of combinations of stamping or marking units; It will be obious that the number of the side-by-side bars of the series of pairs of stamping bars may be varied by increasing or decreasing them, or that some of the bars may be used as blanks, without stamping abutments, should spacing be desired.

Also, that various other changes or modifications as to size, dimensions, or detail construction of the difierent elements of the invention may be readily made by the skilled. mechanic, but that all such changes are to be understood as within the scope of the following claims.
