14 Claims.

This invention relates to the indenting of'type characters in the metallic surface of a medal or the like, and particularly the invention relates to apparatus whereby names and other information may readily be indented uniformly and in properly spaced locations in the surfaces of medals of different sizes and kinds.

It has of course been the practice in the past to form names and other information in the surface of medals or the like by indenting the appropriate type characters in such surfaces, but as heretofore known, this indenting operation has usually been performed either by the preparation of special indenting punches or through the use of manually operated punches that are manually put into position for the indenting operations, In accordance with past practice, the accurate and neat location of the indented characters and uniformity of the indented impressions upon a medal or the like have been difficult to accomplish, and to enable this to be done in a simple and expeditious manner is an important object of the present invention. Other and related objects are to facilitate the location or positioning of indented characters in medals and like objects, to compensate for variations in thickness of such medals and the like so as to insure uniformity of impressions, to enable a single machine to be employed for indenting names and other data in proper positions on medals of various sizes and shapes, and to enable the machine to be readily changed or set for operation on any desired one of a plurality of kinds of medals or the like.

In the production of indented data on medals or the like, it is desirable that the lines of type characters indented therein be centered in a vertical direction on the surface of the medal, and a further object of the present invention is to simplify the attainment of the desired location of the lines of indented characters formed on a medal or the like. An object related to the foregoing is to afford a different mounting member for each kind or type of medal that is to be operated upon by the apparatus of the present invention, and to incorporate in each of the holders, a portion of a line spacing means so that the line spacing means of the machine are automatically coordinated with the particular mounting member that is in place in the machine.

A further object related to the foregoing is to enable medals or the like to be mounted and supported upon mounting plates that are adapted to the particular configuration of the medal or the like that is supported by such plate, and to enable such plates to be readily mounted in or removed from the machine when a different type of plate is to be mounted therein. Another object is to simplify the mounting or removal of work supporting members or plates in a machine of the aforesaid character, and to incorporate in such plates a series of line-spacing abutments that are related to the location of the Work supporting elements on such work supporting plate.

It is of course important that the lines of indented characters formed in medals or the like be accurately centered laterally of such medals, and to enable this to be accomplished in a simple and expeditious mamier is a further object of this invention.

Other and further objects of the present invention will be apparent fromthe following description and claims and will be understood by reference to the accompanying drawings which, by way of illustration, show a preferred embodiment and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle. Other embodiments of the invention embodying the same or equivalent principle may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

For purposes of disclosure, the invention is herein shown as embodied in an indenting machine Hi, the front elevation of which is illustrated in Fig. 1 of the drawings, and this machine is under the present invention arranged so that medals, as 12A of Figs. 6 and 7, medals I2B of Figs. 8 and 9, or medals, as [20 of Fig. 1, may

have names and other pertinent data indented therein as indicated at l3 on the back or rear surface of such medals. Medals of the character shown in Figs. 6 to 9 of the drawings, are made in various shapes and forms, but in every instance it is the practice to provide a flat surface i l on the back of such medal to receive the name of the recipient and other data that are to be formed on each such medal so as to show the ownership of the medal and the facts concerning the award of such medal. The fiat rear surfaces l4 that are provided on such medals are of different sizes and shapes so that with respect to each type or kind of medal it is nec essary to arrange the name and other data'on the flat surface It in a different manner, but in every instance it is desirable to have, this indented information be substantially centered both horizontally and vertically with respect to the flat surface It, and such location and centering of the data I3 is rendered relatively easy through the use of the present invention.

The indenting machine IU of the present invention is, in many of its fundamental structural aspects, substantiallysimilar to the embossing machine shown in the Duncan and Hubbard PatentNo. 1,831,103, patented November 10, 1931, and the structure shown in the aforesaid Dun- I can and Hubbard patent has, in accordance with the present invention, been modified and rearranged so as to facilitate the formation of the data I3 on different kinds and type of medals in theproper centered relationship upon the flat surface M of the medals as [2.

The machine l0 has an upstanding frame that has a constantly rotated vertical shaft 20A, Fig. 11, mounted therein, as shown in the aforesaid Duncan and Hubbard patent, and this shaft has a punch head 2! fixed thereon so as to be rotated with the vertical shaft 20A.' The punch head 2| has a plurality of punches 22 disposed in vertically slidable positions about and adjacent to the peripheryof the punch head 2| so that when a particular punch 22 is disposed in an operating position adjacent the front of the machine, this punch 22 may be operated downwardly through an operating or indentin stroke, and a character formed as the punching element on the lower end of such punch serves in such operating stroke to indent this character in a medal l2 or the like that is supported in an operating position beneath the punch. The punches 22 are selected so as to afford all the necessary characters which are to be indented into the work pieces or medals i2, and in the present case the various letters are all upper case letters, but it will beunderstood that in some instances sufficient punches 22 might be provided to enable both upper case and lower case'charact'ers to be formed. I

The punch head 21 is constantly rotated, and

' the aforesaid Duncan and board and stop means that are fully illustrated and described in the aforesaid Duncanand Hubs bard patent. When a particular punch has been selected and stopped in the operating position, this punch is driven through its operative indenting stroke, and this actuation of the punch is accomplished by means that are of substantially the same character as the operating means disclosed in the aforesaid Duncan and Hubbard patent. It should be observed however that in Hubbard patent there are opposed upper and lower heads that carry opposed pairs of punches .and dies, and these punches and dies must be actuated in timed relation toward and away from each other, but in the machine of the present invention, the lower head, which is identified herein as 2IA does not carry forming-elements or punches, and this lower head 21A is utilized only as a means for carrying a register ring 24 that functions as in the aforesaid Duncan and'Hubbard patent in attaining accurate positioning of the head 2! after a particular punch 22 has been selected. In viewof the foregoing, the mechanism that is utilized in the aforesaid Duncan and Hubbard patent for actuating the forming elements carried by the,

lower head 2IA has been eliminated in the present machine, buttheactuating mechanism for operating the forming elements of the upper head is utilized in thepresent instance in substantially the same form and relationshipthat is disclosed in the aforesaid patent. Thus an arm 25 is pivoted at 26 on the frame 20 so as to extend over the 'operatingposition of the machine, and means are provided on this arm 25 for imparting downward operating movement to the'punch 22 that is-in the operating position and for retracing the punch to its elevated position shown in Fig. l. 'The arm 25 is actuated in a downward direction by means that are shown in the aforesaid Duncan and Hubbard patent and which include the toggle mechanism 36 and an anvil 32 of said patent that is operated by such toggle means. can and Hubbard patent is operated through substantially vertical reciprocating movements: 7

means shown in the aforesaid Duncan and Hub- 1 bard patent after the selected punch 22 has been stopped in the operating positionof the machine.

In forming the indented characters in theflat surface I l of a medal as I2,.the medal is supported in the operating position beneath the selected punch 22 by means that provide for character spacing as well as line. spacing movements of the medal at appropriate times in the operation of the machine. Thus the machine has a supporting rail 35 extended along the forward face of the frame 20, and'a'carriage '36 is mounted for reciprocating movement along the front of the machine by means including upper rollers 3'! and lowerfront rollers 38. The carriage 36 is in The aforesaid anvil of the,.Dun

the present case urged in a right-hand direction, Fi 1, by means including a spring biased tensioning band 38 of conventional form, and such movement is controlled by escapement mechanism, not shown, that is operated near the end of each machine cycle in the manner disclosed in the aforesaid Duncan and Hubbard patent. In the left-hand or carriage return movement, the initial position of the carriage 36 is limited and determined by a stop plate 40 that is secured by screws 4! to the forward face of the guide rail 35 so as to lie in the path of a rigid element or lug 42 of the carriage.

The requisite line spacing movements of the work or medal I2 with respect to the operating position of the machine are attained by means including a cross slide d5 that is mounted on the carriage 36 for movement in a front to rear direction, that is, transversely with respect to the direction of character spacing movements of the carriage 3t. The cross slide 45 includes a pair of side bars ML and dfiR and an integral conecting web 51 that supports the side bars 46L and 46R in a rigid and spaced relationship with respect to each other, and guide means for supporting the cross slide on the carriage are associated with the side bars 68L and 46R. Thus the side bar 46R has a pair of

rigid lugs

48 and 49 extended outwardly from the opposite ends thereof, while the side bar 46L has a rigid lug 59 extended outwardly from the rear end of the side bar. The lugs 38 and $9 on one side of the cross slide and the lug 50 on the other side of the cross slide are associated with guide means supported by the carriage 35, and in the present instance the carriage has a pair of upstanding bearing members 5 IL and 5 FR formed rigidly thereon and in a spaced relation such that the main body of the cross slide 45 may move in a front to rear direction between the bearing members 5|L and 51R. The bearing member 5iL has a guide rod 52L fixed thereon so as to extend horizontally in a rearward direction therefrom, and the lug 50 of the cross slide is apertured so as to slidably embrace the guide rod 52L. The bearing member iilR has a slide rod 52R fixed thereon in a horizontal position so as to extend frontwardly as well as rearwardly from the bearing member 5 lR, and the lugs 48 and 59 are apertured so as to slidably embrace the opposite extended end portions of the guide rod 52R. Thus the cross slide is supported for horizontal movement in a front to rear direction, thereby to enable a workpiece such as a medal l2 carried on the cross slide to be line-spaced with relation to the operating position of the machine.

In enabling different kinds and shapes of work pieces or medals E2 to be supported on the cross slide 45, the present invention provides a specially formed work holding means for each type and design of medal, and such work holding means are removably associated with the cross slide 45. Such work holding means in accordance with the present invention not only serve to support and position the Work with relation to the cross slide, but also embody means that are related to the size and form of the particular work piece or medal so as to constitute a portion of a line spacing means for determining the line spacing positions of the cross slide 45. Thus as herein shown in Figs. 1 to 5 of the drawings, such work holding means are afforded, as to each type of medal, by a work supporting plate 60 that is adapted to be removably positioned in a predetermined relationship on the cross slide 45. The

work supporting plate 60 is of rectangular form and is adapted to rest at its opposite edges on upwardly facing shoulders BIL and SIR that are formed respectively on the side bars 48L and 46R. The supporting shoulders GIL and MR are disposed at the adjacent edges of the side bars in which they are formed, and near the forward edges of these side bars, the work supporting plate 60 is held in engagement with the respective shoulders 6 IL and 6 IR by overhanging ledges ESL and 63B, which serve in effect to provide grooves ML and 64R, through which the work supporting plate 60 may be moved in a front to rear direction when it is desired to mount or dismount such work supporting plate. Near one of its forward corners, the work supporting plate has a positioning lug 65 rigidly secured thereto as by riveting at 66, and as the work supporting plate is moved rearwardly into position on the cross slide 45, the lug 65 engages the forward end 6'! of the ledge 63L, thereby to limit the rearward movement of the work supporting plate 68. When the work supporting plate has reached the predetermined position that results from the abutment of the lug 65 with the surface 61, the plate 60 is held in such position by a releasable latch ii! that is pivoted intermediate its ends at H so that the latch 10 may have the upper end thereof moved into abutment withthe forward edge of the lug 65. When the latch 18 is in the position shown in Fig. 1, the work supporting plate 50 is held against front and rear movement by the cooperating action of the shoulder 6'? and the latch H3, while the engagement of the lateral sides of the plate 69 with the sides of the grooves ML and 64B and with the rearward extensions or shoulders ML and MR that define the shoulders BIL and SIR serves to hold the plate til in position in a lateral sense. When the work supporting plate 60 is to be removed, the latch 10 is pivoted in a counterclockwise direction, Fig. 1, so as to be out of the path of the plate Bil, whereupon the plate may be withdrawn in a forward direction.

It will be recognized that the forward or front faces of ,the different kinds of medals or the like that are to be operated upon by the present machine will diifer quite Widely in size as well as configuration, and each work supporting plate 60 has a work embracing structure 15 formed thereon that will not only conform with the size and configuration of the forward surface of the medal, but will also serve to hold the medal in position on the plate 60. Thus the work embracing structure 15 as herein shown includes a generally annular outer ring 16 that has a space or slot 11 in its forward edge through which the fastening or supporting element HA of a medal may be extended, and the ring 16 is secured in place on the upper surface of the plate to by means such as rivets 18. In the space within the ring 16, a matrix 19 is formed from a suitable moldable material so as to conform with the general configuration of the forward face of the medal that is to be received in the work embracing means 15, and as shown in Figs. 2 to 4, this matrix is adapted to receive the medal that is known as the Purple heart. The matrix 19 of course cooperates with the form or configuration of the medal to prevent lateral displacement of the medal with respect to the work supporting plate 60, and this action is rendered more effective through the use of a clamping means such as a spring clamp that is secured in position on the ring 16 by means such as a screw 8|, and

7 85 as will now be described.-

the spring clamp 89 extends-upwardly and then' forwardly 'oversthe matrix-19so as to engage that portion of the medalthat is remote from the slot Tl. Thus in the mounting of amedal in the work embracing means IE-,such medal: is moved rearwardly into position beneath the spring clamp 80 so as to beheld thereby in cooperative engagement withthe matrix 19; 1 When a medal is thus positioned, the supporting ribbon portion 82 of the'medal extends forwardly and is supported on the flat upper surface of the forward portion of the plate 89. I

In practice it has been found that best results are attained by removing the work supporting plate '69 from the cross slide for the purpose .of mounting a medal I2 in position thereon, and the plate 88 and the medal carried thereby are then put into position on the cross slide 45 by inserting the plate into position in the slots ML and 843.; After movement of the plate fill to its most rearward position, the latch is rendered effective so-as to hold the work supporting plate 69 in this predetermined relationship. When the work supporting plate is thus positioned on the cross slide 45, means that'are associated with the plate Eli-are effective to cooperate with means on the carriage 3am .control and govern the line spacing positions of the cross slide 45 and such control is so related to the location of the work piece or medal on-the plate 89 that the lines of characters formed on the medal will be disposed in a proper location upon the surface M of the medal. Thus each work supporting plate 89 has a stop member 85 secured as by rivets 86 on the lower face of the plate 68 and the stop plate 85 is adapted for-cooperation with a shiftable stop arm 88 that-is-mounted on the carriage 38. The stop arm 88 has arearwardly facing abutment edge 88A, and the stop arm is'mounted in a substantially'radial relationship on a rock shaft 90-. The rock shaft 99 is extended in a front to rear direction on the carriage 38 and is supported at its'rear end. in a lug 9| formed on the'carriage. At its forward end, the rock shaft 98 is supported in a forward lug 92 that is also formed on the carriage 36,-and

a torsion spring 93 acting between the lug 92 and the shaft 99 serves to rotate the shaft 98 in a counterclockwise direction as viewedin Fig. 1-. It should be observed-that the shaft 98 has a knurled operating head 95 at its forward end so that the shaft 99 maybe rockedin a clockwise direction in opposition to the action ofthe spring 93, such rocking movements -being utilized to cause line spacing movements of the" cross slide The stop arm 88 is so urged by the spring 93 that when the cross slide 45 is empty, or in other words when a work supporting plate 80 is not in position on the cross slide 45, the upper end of the stop arm 88 will be disposed in whatmay be termed aninaotive or left-hand position as viewed in Fig. 1, this position being determined by an upper portion "883 ofthe arm 88 that overlies the upper surface of the lug 9| so as to limit rocking movement of the arm. V

When a work supporting plate 80 isinserted rearwardly into position on the cross slide 45, 2 cam surface 98 that faces rearwardly and to the right and which isformed on the stop plate 85, moves into engagementwith the stop arm 88, thereby'to 'rock the arm 88 to the right,

and this enables the rearward movement ofthe plate to proceed. When the stop plate has moved rearwardly for a substantial distance; it moves along what may betermed a, dwell surface Moon the edge oi the stop plate 85, and-this dwell surface 9l then moves out of the path of the arm 8860 that-the spring 93 mayoause returnmovement of the arm 88-toward the leftalong a shoulder 98-3 and into engagement with an abutment 99- 3. Further movement of the cross slide in a rearward direction moves the abutment 99-3 out of the path of the arm 88 and thearm thereupon moves along a shoulder 98-2 and into engagement with an abutment 99-2. Similarly, as the rear the operator then releases-the cross slide which is then urged yieldingly in a forward direction by a spring I88 that acts between the transverse member n of the cross slide 45 and the forward lug 9'2of the carriage. The cross slide 45 thereby moves forwardly'so as to shift the shoulder 98-! into firm engagement with the edge 88A of the stop arm 88, and such engagement determines the first line spacing position of'the cross slide} When the cross slide is to be shifted to its second line spacing position, the head 95 is turned in a clockwise direction, Fig. 1-, in an amount sufficient to move the arm 88 laterally off of the shoulder 98-4, and into alignment with the shoulder 98-2; whereupon the spring I88 shifts the cross slide-in a forward direction and into its second line spacing position; Similarly, a -further rocking movement applied to the head 95 will move the arm 88 into alignment with the shoulder 98-3 sothat the spring I89 may shift the cross slide 45 into its third line spacing position.

It will beclear of course that the location of the stop block 85 on the lower face ofthe plate 88 may be accurately related to the location of the workembracing structure 55, and, both of these elements may be accurately located on the plate with respect to the positioning lug 65 so that when the work-supporting plate 68 is in position n the crossslide 45, the abutment block '85 on the plate 68 will cooperate with the stop arm 88 on the carriage to accurately locate the various lines of indented characters on the surface N3 of a medaL- v 7 It is of course important that the lines of i ndented characters formed on the surface 'M" of a medal be accurately centered transversely-of the surface A, and to enable this to be accomplished; indicating means are provided on the machine for indicating the positionof the carriage and for enabling-accurate setting of the carriage so as to locate such lines of characters-in centered position. Such means as herein shown are afforded by a scale lit-secured at H l to the forward face of the guide rail is pivotally supported at H3 on the guide rail so as to cooperate with the scale Ill], and this pointer is'formedas one element of-a bell crank,

the other arm I it of which extends upwardly and 1 is connected by alink iii to'an arm H6 that is rigid with the carriage 35. Thus the pointer H2 is moved-along the scale i-i il'so as to be indicative 85 somewhat to the right of the range of travel of the carriage 36. A pointer H2 vertical center line of a medal mounted on a work supporting plate 60 is disposed in the operating position of the machine, the pointer will be located at a center mark of the scale III]. The other markings of the scale III) indicate the successive character spacing positions of the carriage 36 on opposite sides of the central position thereof. Thus the operator may count the num ber of letters or letter spaces that are to be included in a particular line of the medal, and through the use of this scale IIO, may set the carriage 36 so that the line of characters will be properly centered laterally of the medal.

As will be evident in Figs. 10 and 11 of the drawings, the mounting plate 60 projects rearwardly or to the left substantially beyond the

lugs

49 and 50 and the ends of the supporting surfaces BIL and GIR, and this relationship is utilized in enablin the'machine of the present invention to produce uniformly indented characters even though there is inevitably some slight variation in the thickness of medals of a particular type or kind. In other words, the tolerances imposed in the manufacture of such medals are often relatively large so that variations in thickness may in many instances be of such magnitude as to tend to produce uneven indenting of the characters, and means are aiforded under the present invention to prevent this undesirable result.

Thus the overhanging relationship of the rear end of the supporting-plate 60 is utilized to enable the work to move downwardly a slight amount when the work is engaged by a punch 22, and such downward movement is resiliently resisted by a yieldingly mounted anvil I20 that is mounted at the embossing position beneath the plate 6!) on a rigid cross bar I2I of the machine frame. The cross bar I2I has a vertical guideway I22 formed therein which receives and slidably supports a complemental guide stem I23 formed integrally and in a depending relation on the anvil I20. The anvil I 20 is in the form of a head at the upper end of the stem I23, as will be evident in Fig. 12, so as to project laterally over an upper surface IZIA of the cross bar I2I, and a pair of coil springs I25, disposed in downwardly facing bores I25 in the anvil, act against the surface I2IA to urge the anvil in an upward direction. Such action of the springs I25 is limited by an adjustable stop means associated with the stem I23. Thus a threaded stud I 28 is mounted in the stem I23 so as to project downwardly beyond the lower surface IZlB of the cross bar I2I, and a washer I29 disposed on ,the stud I28 engages the surface i2 IE to limit such upward movement of the anvil 125! by the springs I25. The stop washer I29 may be adjusted by a pair of lock nuts I36 threaded onto the stud I23, thereby to enable the normal or uppermost position of the anvil I29 to be accurately adjusted.

The form of the anvil I20 is in the present case arranged to aiforcl clearance for the head 2IA, as shown in Fig. 11, and for this purpose is slotted at IZQA along its rear face. Moreover, in order to facilitate insertion of the plate 60, the forward upper face of the anvil is arranged to slope downwardly as at IZEIB.

With the arrangement thus afforded, the indenting or impression forming action of a die 22 is governed by the action or reaction of the springs I25, and uniformity of the indented characters is thus assured. Thus, the variations that are encountered in the thickness of medals of a particular kind are rendered immaterial, and high quality work is assured.

- the preferred embodiment of my invention, it is 10 From the foregoing description it will be apparent that the present invention enables indented characters to be formed in medals or the like in a simple and expeditious manner and insures uniformity of the indented impressions. Moreover, the present invention enables these indented characters to be readily located not only In the desired laterally centered location, but also in such a relationship that the various lines of characters are properly disposed upon the surface of the medal or the like. The work holding plates 60, each having the interrelated work embracing means, line spacing abutments and locating or positioning lugs formed thereon, enable such work to be performed in the same machine on a large number of different kinds or types of medals, and there is no loss of time in adapting the machine for the performance of indenting operations upon different kinds or types of medals.

Thus, while I have illustrated and described to be understood that this is capable of variation and modification and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and alterations as fall within the purview of the following claims.
