OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS v GLOBE STAMPING APPARATUS.

Application filed May as,

My invention relates to stamping apparatus and particularly to stamping apparatus of a rotary type for continuously applying a design upon the exterior of glass globes and articles of like nature.

The uniformity, continuity and distinctiveness of designs applied to glass globes and the like are the factors which to "a large extent determine the salability of such articles, and in general an object of my invention is to provide a stamping apparatus of simple and durable construction which is designed to accurately and continuously apply a design to the exterior surface of aglobe which will have sharp and distinct marginal characteristics. a

More specifically it is an object of my invention to provide an apparatus of the instant nature having a rotary platen, the peripheral surface of which is adapted to engage anadjacent outersurface of a rotatably mounted gl0be,the rotation of the platen with the globe serving to effectively stamp said globe with a suitable design.

My invention further contemplates the provision of a globe stamping apparatus which includes a rotary platen having a resilient printing strip detacha'bly secured along the peripheral surface thereof, said strip adapted to be adjustably positioned along said peripheral surface.

A further obj ect of my present invention is to provide an efficiently operable globe stamping apparatus having a rotary platen for continuously applying a design to the outer surface of a rotatably mounted globeor bowl, and in association therewith I propose to employ a second stamping device for applying a design upon the end portion of a globe, said stamping device being movable axially of the globe and serving as a tailstock to retain the axial alignment of the globe during the association therewith of the rotary platen. J

In addition to the above mentioned advantageous features, my invention contem plates the provision of an apparatus'of the nature set forth in which the rotary platen is rotatable upon a pivotally mounted shaft, said pivotally mounted shaft being adjust- 1928. Serial mfasrosv.

able to facilitate the swinging of the platen between the globe surface and a roller which is provided with a coating of the material which is applied to the globe by the rotary platen.

More specifically,t a further object of my invention resides inthe provision of a globe stamping apparatus having a rotary platen which is rotatably and adjust-ably mounted upon a pivotalshaft, said pivotal shaft also being adjustable axially and laterally, said adjustable features serving to render the pivotal shaft capable of supporting the ro-' taryplaten in a very accurate or exact position with respect to the surface of the globe to be stamped, thereby enabling the stamping apparatus to be used for stamping globes of varied designs and shapes.

These and other obJects will be more-apparent from the following detailed description'when considered in connection with the v accompanying drawings wherein:

Figure l is a side elevational view of a stamping apparatus which is representative of one embodiment of my invention, certain portions of the globe supporting parts being broken away for the purpose of more clearly illustrating the functional characteristics thereof;

Figure 2 is a plan view of the device shown in Figure 1;

Figure 3 is a fragmentary sectional view of a peripheral portion of the rotary platen taken along the line 3-3 of Figure 1;

Figure 4'is an enlarged fragmentary vertical sectional view of the engaging portions of the rotary platen and globe taken substantially on the line H of Figure 2; and

Figure 5 is a horizontal sectional view of the engaging portions of the rotary platen and the globe as viewed along the line 5-5 of Figure 4, the material which is applied to the globe by the rotary platen being shown as having considerable thickness for the purpose of more clearly illustrating the stampingaction ofthe platen 1 Referring now to the-drawings wherein like numerals have been employed to designate similar parts through the various figures, it will be observed that an apparatus I of rivets or the like.

embodying features of my invention includes a suitable frame or bed 10 and near one extremity of this bed ll mount a vertical shaft 12, Figure l, which supports a bowl mounting 14 at its upper extremity. The lower extremity of the shaft 12 carries a bevel gear 16 which meshes with a companion bevel gear 18 mounted upon a shaft 20 and it will be apparent that when rotation is imparted to the shaft 20 through the agency of a suitable handle 22, rotation will be experienced by a globe or bowl 24 carried by the mounting 14. The peripheral surface 26 of this globe 24 is adapted to be engaged by certain elevated portions of a resilient printing strip 28 of a rotary platen indicated generally by the numeral 30.

This platen 30 comprises a body portion 32 constructed of any suitable material such as wood or the like and is rotatable upon a shaft 34. The platen 30 may be adjusted axially of the shaft 34 through the agency of positioning collars 36 and 38 and by reason of the fact that the shaft 34 is pivotally mounted at its lower e'xtremitynpon a head 40, the platen may be swung into and out of engagement with the surface 26 of the globe 24. The aforementioned raised portions of the resilient printing strip 28 present a definite configuration or design 42 and it will be apparent that if these raised surfaces are supplied with a coating of printing material, and then moved into engagement with the surface of the globe 24, said design will be applied to said globe surface when the handle 22 is actuated so as to rotate the globe.

In order to retain the printing strip 28 in proper position upon the periphery of the platen, it will be observed that I provide the extremities of said strip with clamping plates 44 which are secured to said strip by means Each ofthe bent portions 46 of the clamping plates are provided with a number of slots designed for association with clamping pins or keepers 4 8. These keepers or pins 48 are adjustably threaded within the heads of screws 50 secured to the platen and it will be observed that I provide recesses 52 within the peripheral portion of the platen to receive said keepers and clamping strips, as clearly shown in Figures 1 to 3 inclusive. By having the clamping pins or keepers 48 adjustable within the heads of the screws 50, I am able not only to securely retain the printing strip 28 tightly stretched around the platen, but I am able to accurately adjust the printing strip along the platen surface when the occasion demands. The practical value of this con: struction will be more apparent when it is understood that by reason of this adjustable characteristic the design 42 upon the printing strip may be slightly stretched or changed to account for variations in the size of the globe to be printed. In other words, a globe end surface of said globe. Obviously the 7 menace of one size, as for example the globe 24 shown in Figure 1, when moved through one complete revolution in contact with the platen printing strip 28, will receive the design in such a manner that the point where said design is initially and last applied upon the globe will be in proper alignment or uniformlycontiguous. If however, a globe which is slightly larger than the globe 24 is stamped with the same strip 28, obviously an irregularity or non-uniform continuity will appear at the place where thedesign begins and ends because the length of the active portion of the strip will not correspond with the circumferential length of the globe. To meet such conditions, I employ the adjustable keepers or pins 48. It will thus be apparent that in order to enable the use of the same printing-strip 28 for stamping a design on a globe which is slightly larger in diameter than the globe 24, said strip must be slightly stretched and I accomplish this by manipulating the adjustable pins 48. Likewise, if only certain of the globe diameters vary slightly from the standard diameter, the pins 48 may be adjusted so as to slightly stretch the strip 28 along its upper or lower margins so as to accommodate the variation in the globe diameter. By clamping the extremities of the printing strip 28 in the manner described, a very convenient means is presented for mounting said strip upon the platen and for adjustably positioning said strip'in accordance with the particular type of globe which is to be stamped.

In order to retain a globe in a. fixed position upon the mountin 14 during the stamping operation, I provide a tailstock member 54 which is vertically .slidable upon a shaft 56, the vertical movement of said tailstock 54 being accomplished through the agency of a foot pedal 58 pivotally mounted upon the lower portion of the machine frame 10, Figure 1. The inner extremity of this foot pedal 58 has a slotted engagement with a vertical actuating rod 60, the upper end of which carries a horizontally disposed arm 62 and this arm 62 has a yoke connection 64 with a grooved collar 66 which supports the tailstock 54. A coil spring (38 which encircles the rod 60 and is interposed between a lugTO fixed to an upright frame member 72 and a collar 7 4 secured to the rod 60, serves to nor mally urge said rod downwardly, thereby causing the lower surface of the tailstock 54 which carries a resilient printing sheet 76 to engage the end surface of the globe 24. By depressing the foot pedal 58, the tailstock 54 will be moved upwardly so as to permit the removal and insertion of a globe. It will be observed that this tailstock 54 not only serves a means for maintaining the proper position of the globe, but also serves as a means for applying or stamping a design upon the lower portion of the tailstockmay be shaped in accordance with the particular typeof globe to be stamped and in the event thatno design is desired to be applied to the end of the globe, the resilient material 76 will merely .the upper extremity ofavertical shaft 80. In

' order to facilitate swinging the platen upon the head 40, a suitable manipulatin handle 82 is provided which extends latera ly from the lower portion of the shaft 84, and in grder to maintain the proper constant pressure of the printing strip 28 against the globe 24, a suitable coil spring 84 is employed which is connected between the lower portion of the shaft. 34 and a pivoted arm 86. When the pivoted arm 86 occupies theposition shown in Figure 1, the coil spring 84 is rendered effective, but when said arm is swung in a counter-clockwise direction through an angle of 180 degrees, the tension in said spring is relieved so as to permit the platen to be freely swung away from the globe. The shaft 80 is vertically adjustable within a block 88 which is horizontally slidable within the frame or machine bed 10. From the foregoing it is to be understood that by having this block 88 horizontally adjustable, the shaft 80 vertically adjustable therein, and the platen axially adjustable upon the shaft 34,

adjustments may be made to properly position the printing strip of the platen withrespect to the surface of the globe to be stamped. i'his adjustable feature is in addltlon to the adjustable feature above referred to in connection with thedescription of the,

clamping pins or keepers 48. It will be seen that by having this adjustable arrangement,

" variations in the surface inclination of the' globe may be compensated for and my improved stamping apparatus is adapted to be used for stamping globes which vary between a wide range of sizes and shapes. At one extremity of the bed 10, to the left Figures 1 and 2, l'provide a supply roll 90 which is rotatably carried upon a shaft 92,

which has a pivoted connection with the upper extremitypf a sleeve 94. This sleeve 94 is slidable upon a rod96 which is pivotally supported at 98 upon the bed 10. I provide the surface of this roll 90 with a supply of printing or stamping material, and in order Y to supply said material to the printing strip 28, it is only necessary to swing the platen to the left, Figure 1, so as to carry the strip into engagement with the surface of the roll 90 and by' manipulating a handle 100 extending upwardly from the platen, the entire surface of the stamping strip may be supplied with printing material. The manner which the supply roll '90 is mounted serves to enable the positioningof said roll in accordancewith the position of the printing spring 84 to permit the platen to be swung to the left so as to carry the printing strip into association with the supply roll. -By depressing the foot pedal 58, the tailstock 84 is raised sufiiciently to allow the globe to be positioned within themounting l4 and if it is desired to stamp a design upon the end surface of the globe,-printing material may be applied to the surface of the resilient plate 76. Upon releasing the foot pedal 58, the coil spring 68 causes the tailstock to be lowered against the globe, thereby securing said globe in proper axial alignment within the mounting 14. After the. proper adjustments have been made, such as by varying the position of the block. 88, the shaft or the axial position of the platen upon the shaft 34, said platen inay be swung to the right so as to carry the proper portion of the printing strip 28 into engagement with the surface 26 of the, globe,,and the foot pedal depressed, to

permit said globe to be replaced by another. In the event that it is necessary to slightly shift the design in order to effect the uniform continuity at thebeginning and end portions of the design, it is only necessary to adjust the -clamping pins or keepers 48 as above described- From the foregoing it will be understood that my invention provides a stamping device which is adapted to efliciently apply designs upon glass globes and the like which are. clear and distinct and which are uniformly contiguous at the place where the design upon the globe begins and ends. The

importance of obtaining this uniform continuity will be readily appreciated in instances where the design is not composed of separated configurations but comprises lines or figures which extend continuously around the surface of the globe. In such instances it the design does not start andtinish at eX- actly the same position upon the globe sur-' face, the irregularity or non-uniformity which is presented seriously impairs the ornamental appearance and hence materially affects the salabilitv of the globe. It will also be seen that my device is easily operable and serves to greatly accelerate the speed with which'globes may be stamped. The tailstock device which I employ serves as a very effective means for retaining a globe in position and at the same time provides a very satisfactory means for applying a design upon the end surface of the globe. T he adjustable features which have been described are very important from the standpoint of rendering the invention adaptable for use in'connection with handling globes which vary between wide ranges of sizes and shapes and the ease and speed with which my improved machine may be operated are factors which enable the economical manufacture of stamped globe units.
