. ROTARY STAMPING DEVICE.

Specification of Letters Patent.

Application filed March 27, i920. Serial No. 369,248..

To all whom it may concern:

Be it known that I, JULiUs MEREY, a citizen of Hungary, (who has applied for United States citizenship,) and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and. useful Improvement in Rotary Stamping Devices, of which the following is a full, clear, and exact description.

My invention relates to improvements in rotary stamping devices, and it consists in the combinations, constructions and arrangemonts herein described and claimed.

An object of my invention is to provide a novel form of rotary stamping device for stamping letters, numerals, and the likeinto metals.

A further object of my invention is to provide a device of the type described in which means is provided for adjusting the die holding mechanism with respect to the articles to be stamped so that impressions of different characters can be neatly and quickly stamped upon such articles.

A further object of my invention is to provide a device of the type described in which means is provided to permit the use of dies bearing characters varying in size.

A further object of myinvention is to provide in a device of the type described a novel means for moving the portion of the device si'lpporting the articles in which impressions are to be stamped to insure proper spacing and arrangement of such impressions.

Other objects and advantages will appear in the following specification, and thenovel. features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this ap plication, in which-- Figure is a front face view of the device, a portion being broken away and other portions being shown in section,

In carrying out my invention, I provide a base 1. An upright supporting frame 2. is

Patented Oct. 19, 1920.

formed integral with the base 1. The up- 1 right supporting frame 2 is formed withcentral channels 8 and 4 extending through the upper portion thereof and intersecting at right angles. A guide member 5 (see Figs. 3 and 7) is slidably disposed within the guideway 4 and is maintained in horizontal position by a washer 6 which is carried upon a stud bolt 7 which is screwed into a threaded opening 8 in the end of the guide member 5 and which is maintained in position by a nut 9 which is screwed on the end of the stud bolt 7. A recess 10 in the guide member 5 is adapted to receive the lower end 11 of the connecting rod 12 which is pivoted therein by a pin 13 which is inserted through an opening 14: in the guide member'fi. The upper end 15 of the connecting rod 12 is pivotally secured to an eccentric portion 16 which is formed integrally with'a shaft 17 and serves as a crank.

The shaft 17 is journaled in a housing or crank case 18 which is of the form illus trated' in Fig. 5 of the accompanying drawings. Thehousing 18 is slidably disposed in the guide ways? and 41 and is maintained in horizontal position by a washer 19 which is carried upon a stud bolt 20. The stud bolt 20 is screwed into a threaded opening 21 in the housing 18 and a nut 22 screwed on the end of the stud bolt 20 maintains the .washer 19 in position.

The housing 18 is formed with a vertically extending threaded opening 23 adapted to receive a threaded rod 24: which extends therethrough and which has its lower end inserted through an opening 25 in the guide member 5. The upper end of the threaded rod 24: extends through a plate 26 which is bolted to the frame 2 by the bolts I 27. A bevel gear 28 is rigidly secured to the upper end of the threaded rod 24. A second bevel gear 29, carried at the end of a rod 30 whichis journaled in a bearing 31, is in mesh with the bevel gear 28. The bearing 31 is formed integrally with the plate 26. An arm 32 is rigidly connected cylindrical extension 38.

with the end of the rod 30 and carries at its other end a handle 33. It will thus be seen that the guide member 5 and the housing 18 may be shifted in a vertical plane by operation of the arm 32.

Referring now to Fig. 7, it will be noted that the guide member 5 has an integral laterally extending portion 34. A pin 35 is inserted through an opening in the end of the laterallyextending portion 34. A spring 36 is held between a pin 37 inserted through the pin 35 adjacent its end and the end of the laterally extending portion 34. It is therefore possible to partly withdraw the pin 35 against the tension of the spring 36 from the opening in the end of the laterally extending portion 34. The pin 35 has a function which will be hereinafter set forth.

The guide member 5 has also an integral A sleeve 39 is mounted to rotate upon the cylindrical. extension 38. A disk 40 is rigidly mounted upon the sleeve 39, as best seen in F ig. 3. A second disk 41 is feathered upon the sleeve 39 and may be moved therealong, but is prevented from rotating by a feather 42. The sleeve 39 is maintained in position upon the cylindrical extension 38, by a lock nut 43, and a bolt 46. The lock nut 13 is screwed on the threaded end 44 of the sleeve 39 and the bolt 46, which is loosely disposed in the opening 45 through the lock nut 43, is screwed in a threaded opening 47 provided in the end of the cylindrical extension 38. It will thus be noted that the disk 41 is also maintained in position by the lock nut 43 and the bolt 46. An annular recess 48 is provided in the outer face of the disk 40 around its outer edge. A plurality of openings 49, spaced at equal distances apart, are formed through the disln 40 adjacent its outer edge. The openings 49 register with openings 50 which extend partly through the disk 41. Stub shafts 51 are disposed within the openings 49 and 50, as clearly shown in Fig. 3.

A die 53, which is of the shape shown in Fig. 4, is keyed to each of the stub shafts 51 and is disposed between the disks 40 and 41. plurality of flattened faces formed upon its periphery and that a character 55 is placed upon each flattened face. Each flattened face 54 has a character of a different size from that found upon the other flattened surfaces of the die.

A ring gear 56 is disposed within the annular recess 48 and has its outer rim in mesh with gears 52 which are rigidly secured to the stub shafts 51. A shouldered pin 57 is inserted through registering openings in the disks 40 and 41 and has'a gear 59 rigidly secured thereto. The gear 59 is arranged within a recess 60 in the face of the disk 40 to mesh with the inner edge of the ring gear It will be noted that the die 53 has a 56. An end of the shouldered pin extends through a washer or look nut 61 which is non-circular in form and is embedded in the inner face of the disk 40. The pin 57 is then maintained in position in any approved manner as by upsetting the end thereof or by having a cotter pin (not shown) inserted through its end.

A hexagonal head 58 formed integrally with the pin 57 provides a means for readily operating the gears 59, 56, and 52 to revolve the dies 53 and thereby change the size of the characters which are in position to be stamped into articles as desired. An indicator arm 62 is connected to the head 58 and when the latter is turned, the indicator arm will be moved arcuately along the scale 63 to indicate the size of the character that is then in position to be stamped upon the Work.

A provision of a satisfactory means for moving the work supporting portion of the device to insure the impressions being properly spaced and arranged in the work adds greatly to the efficiency of the device. I therefore provide a cam member 64 which is rigidly secured to the end 65 of the shaft 17. A roller 66 carried at the end of the rod 67 engages the cam 64.' A plate 68 is sccured to the rod 67 by means of a screw 69. Springs 70 are disposed between the plate 68 and a support 71 which is formed integrally with a plate 72 and maintain the roller 66 in engagement with the cam 64. The plate 72 is secured to the frame 2 by means of screws 73. A stud bolt 75 is screwed into the rod 67 at its lower end and is slidably disposed in a slot 74 provided in the upper end of the second rod 77. A nut 76 upon the stud bolt 75 serves to hold the upper end of the rod 77 in slidable relation with the lower end of the rod 67. The lower end of the rod 77 is flattened and is pivotally secured to the center of a disk 78. The lower end of the rod 77 has a lateral extension 7 9 provided with an opening 80 formed there through. The opening 80 registers with one of a plurality of openings 81 formed through the disk 78 and a tapered pin (not shown) may be inserted through the registering openings to prevent the disk 78 from being rotatably moved. The disk 78 has inclined cam members 82 spaced around its outer edge. The cam members 82 taper from the center of the disk toward the outer edge and vary in height. An arm 83, pivoted at 84 to the base 1, has a roller 85 in contact with one of the cam members 82.

It will be understood that the disk 78 may be rotated at will to bring any one of the cam members 82 into engagement with the roller 85 and that only one of such cam members is in operative engagement with the roller during the operation of the device. A spring 86 (see Fig. 8) maintains the roller hers 8'12.

A pawl 87., which is inserted in a slot in the other end of the arm 88, engages the teeth of a rack 89, the pawl being so held 85 in contact with the cam mem- UCJ by the spring 90. A work supporting table 92 has a tapered base 93 slidably disposed in a recess 91 in the base 1. The rack 89 is insorted through an opening 94; in the work supporting table 92 and is held in position by means of a collar 96. An end plate 98 is secured to the work supporting table 92 by screws 99. The collar 96 projects therethrough, a clearly shown in Fig. 2, and a tapered pin 97 inserted through a notch 101 in the collar 96 into the end plate 98 prevents the rotation of the rack 89. Teeth 88 are provided upon a plurality of sides of the rack 89 and vary in size in direct proportion. to the size of the cam members 82.

A wheel or handle 95 upon the end of the rack 89. as illustrated in Fig. 1, provides a means for adjusting the rack 89 so that the pawl 87 will engage teeth of the proper size to move the work supporting table the re quired distance for proper spacing of the impressions. A cotter pin 100 inserted through the end of the rack, as shown in Fig. 8, holds the collar 96 in position. The notches 101 in the collar 96 indicate the side of the rack that is being engaged by the pawl.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The disks -19 and 41 are rotated until the die bearing the character selected is directly above the work supporting table 92. The pin 35. which has been partly withdrawn from the opening in the end of the member 31 against the tension of the spring 36, is permitted to enter one of the openings 49 to prevent further rotation of the disks a0 and 4:1. The die selected will be lowered into contact with an article placed upon the work supporting table when the arm 32 is operated. The crank mechanism is then operated by means of an arm 102 and a handle 103 and an impression is stamped in the work. Operation of the crank shaft 17 019- erates the rods 67 and 77, thereby moving the work supporting table from right to left. The impressions will therefore be uniformly stamped in and arranged upon the work placed upon the work supporting table. It is obvious that forms of the device varying from that illustrated in the accompanying drawings may be provided without departing from the scope and spirit of my invention as set forth in the foregoing specification and outlined more particularly in the appended claims.
