Application filed June 24, 1922. Serial No. 570,589.

To all whom it may concern:

Be it known that we, HARRY M. SEAGERS, a citizen of the UnitedStates, and resident of Geneva, in the county of Ontario and State of New York, and CHARLES D. ConwIN and ALoNzo B. ELY, citizens of the United States, and residents of Groton, in

the county of Tompkins and State of New York, have invented certain new and useful Improvements in Embossing Apparatus, of which the following is a specification.

This invention relates to improvements in embossing apparatus, and more particularly to apparatus for punching characters, or-

paper and forcing the same into a cardboard backing to form embossed signs, dis-- play and advertising cards, and the like.

The invention hasfor its principal objects to provide an inexpensive, compact and efficient press adapted. to develop a very high pressure, with slight effort on'the part of the operator, for forcing the punching type through the colored paper and into the type may be clamped. together and shifted between the bed and platen of the press; to

provide simple means for holding the typeholders in various adjusted positions on the carriage; to provide simple and inexpensive type-holders and locking andsiacingdetion in the'holders; to provide means; for

detachably holding type, 01' rows of type,

in parallel, staggered, or anguiarly disposed lines on the carriage or support; to provlde efiicient means for regulating "the depth of cardboard backing. 5o

The pedestal or base 1 of the press comprises a hollow metal casting,'having aflange 2 heldto a floor or other foundation by bolts 3, and also provided with an integral top plate or platform 4 .upon which the bottom wall 5 of the main body. portion'of the press holes 9 in said plate and finally screwing' on the nuts .7. The press body is thus held against movement in anydnection relatively to the pedestal 1. It willbe obvious that the press body may be detachably secured as above described to any other suitable form of base, such as a work bench, table, or base plate.

The press body comprises an integral heavy metal casting of general rectangular form, the bottom wall 5 of which rests on the top plate 1 ofthe'pede'stal and is connected with the top wall 10 thereof bythe vertical integral side walls ll-and 12. The top. wall :10 ofthe press body is provided with a flat under face 13 lying in a hori zontal. plane and said wall forms the fixed head or platen of thepress. The shi-ftable head or bed of the press comprises a thick lateral extensions or guide portions 15 at opposite ends thereof slidable vertically in guideways 16 formed in the inner faces of the thickened upper portions ll and 12 of the side walls 11 and 12 of the press. The lower ends of the guideways 16 are open to permit ends 15 of the bed to be passed upwardly into the ways in assembling the press. The bed is normally forced downward by a pair of coil springs 17 the upper ends of which are confined in sockets 118 formed in the platen 10.

The bed 14E is forced upwardly through the medium of a steel cam shaft 18 having two flat faces 19 and 20 at diametrically opposite points, cylindrical bearing portions 21 and 22, and a flattened end 23 adapted to engage in a socket 2% formed in one end of a hand-lever 25. A set screw 26, threaded through the wall of the socket end of the hand-lever, serves to detachablyhold the lever on the/end 23 of the cam shaft. The cam 18 is provided with two arcuate, diametrically opposed, working faces 27 and 28. The surface 27 is slightly eccentric to the axis of oscillation of the cam shaft which is coincident with the axial center of the cylindrical bearing port- ions 21 and 22 of the shaft, while the surface 28 is concentric with the axis of rotation of the shaft and the outer surfaces of bearing portions 21 and '22. Surface 27 extends from edge a of flat face 19 to edge I; of flat face 20 and rises gradually from a to 6; while surface 28] extends from edge 0 of face 19 to edge d of face20 on an arc struck from the center of the bearing portions 21 and 22.

The diameterof the bearing portions 21 and 22 is equal to the distance between faces 19 and 20 and also -to the distance between the straight vertical sides of the Vertically elongated bearings 29 and 30 in walls 11 and 12 0f the press body. Bearing 29 is in the form of a recess in wall 11, while bearing 30 is in the form of a slot or aperture in wall 12 through which the vcam shaft is inserted endwise with its fiat faces perpendicular and then rotated to the position shown in F ig. 4, in assembling the machine. This arrangement prevents accidental displacementof the shaft and provides for direct vertical movementas well as axial rotation ofthe shaft when the lever 25 is operated. The inner edge of the socket 24 of the hand lever is formed with a lug or stop 31 adapted to engage stop shoulders or abuti'nents 32 and 33 at opposite ends of a segmental recess 34 formed in a boss 35 on the outer face of the wall 12 of the press body. Thesegmental recess, as shown in Figs. 8 to 10,'is made sufiiciently large to prevent binding of the stop lug 31 owing to the vertical movement of the Cam shaft and hand lever, and said stop lug in conjunction with abutments 32 and 33 serves to limit the eXtent of oscillation of lever 25 and the cam shaft from the position shown in Fig. 4 to that shown in Fig. 5.

The cam 18 is interposed between two rigid and relatively heavy flat plates 36 and 37 preferably formed of cold rolled steel. These thrust plates 36 and 37 are shifted edge wise in opposite diree tions by reason of their frictional contact with the cam shaft when the hand lever is operated. A set of antifi'iction rollers 38, preferably formed of out lengths of cold rolled steel rods, is interposed between the upper face of plate 36 and the under face of the bed 14 of the press. A pair of steel wedge blocks 39 are slidably supported on a raised portion or track 40 formed on the upper face of the bottom wall 50f the press body, said blocks being provided with depending side flanges or guides 41, and the under faces of said blocks being inclined in opposite directions at the same angle the oppositely inclined faces 40 of the track 40 upon which said blocks are slidably adjustable to vary the distance between the (int, horizontally disposed, upper or thrust receiving faces of the blocks and the under face 13 of the fixed head or platen 10.

The blocks 39 are normally urged outwardly toward the lower ends of track 46 by a spring 42 coiled around a supporting rod 43 having its ends slidably confined in holes 44 bored in the inner ends of the blocks. The blocks are adjustable inward ly and outwardly by means of adjusting screws 45 threaded through the side Walls 11 and 12 of the press body and having their inner ends engaging against the outer ends of the blocks.

wall in the press body, and a set of. anti friction rollers 46, similar to the rollers 38, are interposed between the flat upper faces of said blocks and the flat horizontally disposed under face of the thrust plate 37. The ends of the sets of rollers 38and 46 are confined in retainers 47 formed by bending a metal strap to'provide an elongated roller-end-embracing loop and a horizontal stop or projection 48. The ends of the bed 14 are cut away at the under side of the bed, as shown at 49 in Fig. 10, to provide clearances for the retainers 47, and the outer ends of plates 36 and 37 and blocks 39 terminate short of the inner faces of the side walls 11 and 12 for the same purpose.

The front and rear faces of the press body between the bed and bottom wall 5 are closed by detachable metal face plates 50 and 51 held to the press body by screws 52 and preferably countersunk in the press Blocks 39. form an adjustable thrust-recelving base or false bottom body, as shown, to provide a flush construction; The lower portions of the front and rear faces of the bed 14 are also countersunk and these countersunk faces are oven lapped by the upper portions of plates 50 and 51, whereby said plates assist in guiding the bed vertically and also keep the space between the bed and wall 5 closed in the retainers 47 of the upper set of rollers 38, and the rear edge of the upper thrust plate 36, are normally urged roarwardly and heldagainst the face plate 51 by a bowed spring 53. Spring 53 is secured midway its ends to the face plate 50 by rivets 54 and its ends are sufficiently avide to engage the front edge of plate 36 at all times, as shown in Figs. 4 and 5, and to engage the foremost roller 38 during the initial portion of the forward movement and final portion of the rearward movement of hand lever 25. The stops 48 on the retainers 47 of the lower set of rollers 46, and the front ed es of alate 37 are normall held a ainst D 7 CD sets of rollers to the same positions, after each operation of the press and said springs also serve in conjunction with the face plates to prevent creeping of the thrust plates 36 and 37. I

A pair of plates 57, having their ends seated in horizontal grooves in the walls 11 and '12 of the press body, may be employed, if desired, to prevent the possibility of undue tilting of plate 36 in case the bed should be pulled or violently thrown up by a careless or mischievous person, especially when no type and cardboard and paper aresin place on the carriage hereinafter described. These plates 57 may be omitted, however, as the construction and arrangement of parts are such that there is little possibility of substantial tilting of plate 36 and rollers 38 even under most unusual conditions.

It will be obvious that, since thelever 25 and cam 18 have a fixed throw, the closeness of the approach of the bed 14 to the face 13 of the platen 10 may be regulated by adjusting the wedge-lilrebase blocks 39 alongtrack 40. It will also be'obvious that a relatively short forward movement of lever 25 will shift the flat faces 19 and 2 0 all positions of the bed. The stops 4 8 on 7 initial rise to the bed 14:. The remaining relatively long portion of the forward throw of the lever 25 will evidently cause a very slow and relatively slight additional rise of the bed 14. It will also be obvious that omitted, if desired, the bed 1 f being returned by its weight alone.

A table or shelf for supporting cardboard, paper, type, finished cards, or the like, may be provided if desired. We have shown a detachable metal shelf or table 58 provided with an undercut socket or groove 59 at its inner end having an open lower end, whereby said table may be attached to the press body by sliding the same downward to engage a dovetail projection or boss 60, formed on wall 11, in said socket 59.

A carriage, having a plurality of parallel longitudinally extending undercut .ways, grooves or slots 61 therein, is slidably supported on the bed 14; to move longitudinally fore and aft of the press between the thickened upper portions 11 and 12? of the side walls 11 and 12 of the press body. The carriage is several times as long as the foreand-aft width of the platen face 13 and bed 1% so that successive portions of the carriage may be positioned between the bed and platen. For convenience and economy in manufacture, the slotted or grooved carriage is preferably formed by securing a plurality of relatively thick rigid metal bars. 62 by means of rivets 63, or in any suitable manner, to the upper face of a flat sheet metal plate 64. Bars 62 are secured to the plate with the downwardly and inwardly, in-

, c'lined or beveled longitudinal edges of the bars spaced apart to form the slots or ways 61 parallelwith the longitudinal center line of plate 64:. V

The plate or base 6% of the carriage rests upon and slides over the flat top face of bed 14 of the press and is slidably and de tachably held to the bed, and guided to more directly fore and aft thereover, by means of a steel rod 65 having a sliding lit in a hole 66 bored horizontally through the bed 14 from front to rear midway the ends of the bed. Rod 65 may be inserted in, and withdrawn endwise from, the hole 66 when the carriage is detached therefrom. The carriage is attached to the guide and retaining rod 65 byv inserting the reduced forward end 67 of the rod in a hole 68 formed in a flange or tongue 69, stamped downwardly from the forward end of plate 64, and then assin a screw 7 O throu h a holein the rear end of plate 64 and screwing the same into a threaded hole 71 bored vertically through rod 65. Flange 69 is stamped from the plate 64 close to the forward end of said -versely corrugated web 75 overhanging and spaced from the upper face of the adjacent outermost bar 62 on plate 64. Web 7 8 is secured by screws 76 to plate 64. The members or rails just described and the undercut grooves or slots 61 provide means where by two different forms or styles of typeholders 77 and 78 may be detachably and adjustably held to the carriage either separately or together to provide for bet-ups of many different forms. In Figs. 2, 4, 5, 13 and 14; we have shown three of the type holders 7 7 mounted on the carriage, and in Fig. 19 we have shown a group composed of two holders 77 and three holders 7 8 mounted on the carriage.

Both styles of type holders are formed of thin sheet metal and are of the same construction, except at their ends, comprising fiat bases or body portions provided along their forward and rear longitudinal edges with channel flanges 79 and 80. The.chan nels in flanges 80 are deepervertically than the channels in flanges 79, and the flanges 79 and 80 terminate short of the ends of the flat bottoms of the holders. Channel flanges 79 are adapted to receive only the relatively thin ledges 81 projecting laterally from the lower edges of the punching or embossing type blocks 82, while channel flanges 80 are, adapted to receive the thicker ledges 83 projecting laterally from-the upper edges of the type blocks 82, whereby the type blocks, which are inserted sidewise in the holders from the ends of the holders, can.

only beplaced in the holders right side up or with the tops of the typeall along the same longitudinal edge of the holder. The type faces are provided with the usual cutting edges Set adapted to penetrate the colored paper 85 and be forced partly through the cardboard backing 86.

The ends of the bottom portions of the type holders '77 are formed with integral forwardly and'upwardly extending spring tongues 87 having rounded transverse ribs 88 punched upwardly therefrom adjacent their free end'sand adapted to snap into any one of the corrugations in rails .75 to retain the holders in different adjusted positions on the carriage. Holders 77 are adjustable longitudinally of the carriage only, and may be detached from the carriage by sliding said holders forwardly to withdraw their end portions from beneath the forward ends of the corrugated rails 75. Both styles of holders may be made in various widths to take different sizes of type blocks, and holders 78 may also be made of various lengths and are adjustable longitudinally and angularly on the carriage.

The ends of the holders 78 are formed with longitudinal slots 89 adapted to receive the shanks of clamping bolts 90 inserted laterally in the open forward ends of the grooves 61 in the carriage. The heads 91 of bolts 90 have the shape of a four-sided pyramid to permit the bolts to slide freely longitudinally of the grooves and prevent rotation of the bolts. Knurled thumb nuts 92 threaded on the shanks of the bolts serve to securely clamp the holders 7 8 in adjusted position on the carriage. It will be obvious that holders 7 8 may be clamped to the carriage in differ nt diagonal positions, in lines at right angles to the longitudinal center of the carriage or, by' placing the bolts 90 at both ends of the holder in the same slot 61, the holder may be clamped to the carriage on a line extending longitudinally of the carriage. Slots 89 are preferably formed at one side of the center line of holders 78 so that looking plates 93 each having a knurled clamping screw 94.- threaded through the center thereof, may be clamped to the holders close to the ends ther of when necessary. These rectangular locking and type-spacing plates or blocks 93 are each preferably formed of sheet metal and has a raised or upwardly bent portion at oneside thereof so that when thumb screw 9-1 is tightened as shown in Fig. 16, the upper face ofthe block 93 will engage under the inwardly extending edges of flanges 79 and 80. andthe lower end of the screw will bind against the bottom of the holder, thus locking the block against movement longitudinally of the holder. Blocks 93 are employed with both styles of holders at the ends of rows of type to retain the rows of type against longitudinal movement in the holders, and are also used to space words or groups of type in the holders, Tt will be obvious that other forms of type spacers, such as blanktype blocks may be employed, and that screws 9 1 may be omitted from the blocks 93 which are employed as spacers only. I

The apparatus also includes a plurahty of card-holders or supports adjustably, detachably and yieldably held to the sliding carriage for supporting the cardboard backing 86 of the sign or other display card over the sheet, strips or pieces of colored paper 85 which are placed upon the faces of the type 82 in the type-holders after the form or forms are set up. Each card holder comprises a light sheet metal angle bar 95 welded or otherwise rigidly secured adjacent its ends to the raised ends of a pair of light angular spring metal supporting arms 96.

The opposite or lower ends of arms .96 are detachably and adjustably clamped to the carriage by bolts 97, having pyramid heads cially where the number or arrangement of the rows of type in the form is suchthat the cardboard backing 86 would tilt if supported only by the type blocks 82. The holders 95 are useful not only for supporting the cardboard backings, but also for aligning the top and bottom edges of the cardboard backing and preventing accidental shifting thereof. here two holders are employed, by setting them apart the width of the card 86 from top to bottom of the card, they facilitate final accurate arrangement of the type holders as they define on the carriage the area of the card.

The upper faces of bars 62 are scored or grooved at regular intervals along parallel lines at right angles to the path of movement of the sliding carriage to form index lines 99 which cooperate with the parallel longitudinal grooves 61 'to divide the carriage into uniform rectangular areas, These grooves 99 and 61 greatly facilitate accurate positioning of the type holders and card I holders and facilitate final longitudinal ad'- justment of the type blocks in the type holders. A pair of upstanding ears or lugs 100 are stamped up from plate 6 1 of the carriage adjacent. the rear ends of bars 62 and are provided with vertically elongated bearing slots 101. forthe ends of a hinge or pivot rod 102 around which is'ooiled or bent the rear end of a swinging sheet metal plate 103 of approximately the same length as bars 62. h The hinge of plate 103 ispreferably located at a distance from screw 70 slightly greater than the widthof the bed 14 from front to rear, so that when the carriage is drawn forward to the limit of its movement, defined by screw 70 engaging the rear edge of the bed, said plate may be swung upward and rearward beyond a vertical position where it will be supported by the upwardly and rearwardly inclined front face of the platen 10, as shown in Fig. 2.

In the operation of the press, the wedge blocks 39 are adjusted to provide for the desired depth of penetration of the cutting edges of the type blocks 82 into the card board 86, the former forms are set up on the carriage, the piece or pieces of colored paper 85 are, laid upon the type faces 1n the usual way with their adhesive coated sides uppermost, the cardboardbacking 86 is then placed over the piece or pieces of paper with the upper and lower edges of the card seated on the angle iron bars 95, plate 103 is then swung forward and downward upon the backing card 86 to clamp the card and colored paper upon thefaces of the type, the carriage is then shifted rearwardly to position all, or as much of the type as possible, between the bed and platen, the handle 25 is then pulled forward and downward its full stroke and returned to its initial position. If, owing to the number of forms set ,up on the carriage, or the size of the form,

all of the type are not pressed into the paper by the first operation of the press, the carriage is then againshifted rearward and the handle25 again operated. This is repeated until all the type have been forced through the colored paper into the cardboard backing or backings, whereupon the carriage is drawn forward, plate 103 swung upward, and the finished card or cards and surplus paper are removed; The card holders are free to yield downward relatively to the type during the embossing operation, and plate 103 is alsofrce to move downward during the embossing operation owing to 1ts vertical sliding and pivotal connection 101102.

The structure above described provides an embossing press of small size and compact form adapted to develop a pressure of ap proximately twenty thousand pounds with little effort on the part of the operator. The, structure shown also provides means whereby initial forward movement of the hand-lever 25 through approximately onefourth of its throw willca-rry the surfaces 27 and 28 of the cam into engagement with the plates 36 and 37 and quickly liftv the bed 14 three-fourths of its total rise, the final three-fourths forward throw of the hand lever causing surfaces 27 and 28 to ride over the plates 36 and 87 and slowly lift the bed 14 the last quarter of its rise. This arrangement permits adjustment of the press to quickly lift the plate 103 into contact with the platen face 13 by the first quarter stroke of the handle, and affords powerful leverage duringthe ren'iaining three-quarters of the forward stroke of the handle for forcing the type through the paper 85 and partly into the cardboard 86.

It will be obvious that in making very elaborate ornamental signs requiring special type, or very irregular arrangements of type, the type blocks may be placed directly on the carriage, or may be attached by shellac or the like to a paper or metal sheet or plate placed on the carriage, the plate'108 serving to clamp the special form, eard board backing and paper in place on the carriage prior to the squeezing operation of the press.
