6 Claims.

Our present invention relates to a combined hot stamping and perforating press and to the method of simultaneously hot stamping and perforating stationery or the like and constitutes an improvement upon the invention disclosed in Patent No. 1,978,790 granted to us on October 30, 1934.

The primary object of our invention is to provide a press which is capable of use for either separately or simultaneously stamping or im printing and perforating articles of stationery such as writing paper, announcement cards and the like to provide said articles with plain or perforated uni-colored or contrastingly colored, lustrous or metallic foil designs, monograms, insignia,

etc. A further object is to provide a press of the character described which will be inexpensive,

portable and so simple as to be efficiently operable by a person of average intelligence after but a few minutes instruction as to its use. A further object is to provide novel means for automatically simultaneously feeding the color strip carrying the imprinting ink or metal foil and the cushioning strip for the perforating die so as to present fresh portions of said strips to the stamping die for each stamping and perforating operation.

A further object is to provide a novel form of type or die for use with such press whereby the simultaneous hot stamping and perforating of stationery and the like to provide the same with con trasting color designs can be accomplished. A

still further object is toprovide a novel method of ornamenting stationery and the like and the product resulting from such method.

The foregoing and other objects of our invention will be better understood from the detailed description which follows when considered in conjunction with the accompanying drawings, where- Figure 1 is a front elevation of the press embodying our invention, parts thereof being broken away to better show the details of construction.

Fig. 2 is a side elevation of the press shown in Fig. 1 when viewed from the left end thereof.

Fig. 5 isa transverse section taken along the plane of the line 5-5 of Fig. 4.

Fig. 6 is a top plan view of a chase containing stamping and perforating dies.

Fig. 7 is a fractional side elevation of the chase Q5, and diesshown inFig. 6.

Fig. 8 is an enlarged section taken along the line 8--8 of Fig. 6.

Fig. 9 is a fractional plan view of .an article of stationery to which the invention is applicable.

Fig. 10 is a view similar to Fig. 9 of the article after having been operated upon by the stamping and perforating die.

Referring to the drawings, let A indicate a substantially C-shaped frame carried by and preferably formed integrally with a substantially conical base member B which in turn may be formed integrally with or mounted upon a supporting plate C. The upper arm of the c-shaped frame is formed with a depending portion a. having a transverse recess 2a therethrough for accommodating heating means preferably in the form of an electric resistance element D which is removably carried thereby. The front and rear sides of the depending portion are inclined inwardly .and upwardiy from the base thereof to provide a dovetail supporting and guiding means for a palette E which has a complemental dovetail recess. The palette is formed with a socket within which a chase F may be suitably held by a clamping screw (not shown). To facilitate the mounting and removal of the palette from its supporting means the palette is provided with a screw threaded clamping handle e.

The base member B at its top supports a table b and depending from said table and extending centrally through said base member is a stud 21) formed with a rack for cooperation with a pinion g formed on an operating shaft G which extends transversely through an opening in said base. An operating handle 2g is connected to the outer end of the operating shaft for rotating said shaft to raise or lower the table b. A platen H is mounted on the table b and is movable upwardly toward the chase F as the operating handle 2g is moved downwardly. For resisting said upward move ment and for returning the platen downwardly on the completion of a stamping operation there is provided a helical coil spring J. At the rear of the platen there are mounted two plates 11. each of which carries a stud or pin 271. which extend in parallel relation over the top face of the platen and provide guides for a gauge 'bar K which at each end is formed with an opening through which the pins extend. The gauge bar may be held in any adjusted position over the platen by thumb screws 371. or the like. A pair of spring clips k are carried by the gauge bar K and adapted to receive and hold the stationery to be stamped and/or perforated.

Secured to the top bar of the C-shaped frame is a carrying member L near one end of which is mounted a spindle Z extending forwardly therefrom and upon which in turn is mounted a roll of color strip material M which may be of any desired character that will transfer colored ink or metallic foil therefrom to an article being stamped under the influence of heat 'and/or pressure. Suitable means may be employed for providing the necessary frictional resistance to said roll M to permit unwinding thereof under tension. At

the opposite end of the member L upon. a depending lug thereof is mounted a spindle; 31 upon which in turn is rigidly mounted a friction. roller N. In superposed relation to the roller N is a second friction or pressure roller N" carried by an arm 51 pivoted at 51, said roller N being held against the roller N under the tension of a spring Bl. Also fixedly carried by the spindle 32 is a ratchet wheel which cooperates with a gravity activated pawl o to cause movement of the roller N to draw the color strip m from the roll M between the rollers N and N as the platen is raised and lowered. The pawl 0 is pivotally mounted at 20 to one end of a link 30, the other end of which is pivotally mounted on the spindle 32'. For moving the link 30 and with it the ratchet wheel 0 there is provided a rod P, one end of which is fixed to the platen H and the other end of'which is pivotally connected to the link 30 intermediate its ends.

The top face of the platen H underlying the horizontal component of the color strip 112 is formed with a channel extending thereacross, said channel being of two depths 472 and 571, the latter being the deeper and extending centrally of the former. Disposed within the channel 4h so as to lie flush with the top of the platen is a plate h, which latter has a rectangular opening Th underlying the chase F and a second opening 8h provided by bending a portion 971. of the plate 6h downwardly as best seen in Fig. '1. The plate 672. forms with the platen a longitudinally extending recess through which is guided a cushioning strip 1" of heavy paper or the like supplied from a roll R mounted upon a support 21' extending upwardly from the supporting plate C or any other suitable'means.

Depending from the platen H at the rear thereof and preferably in alignment with the. rod P is a bracket having a hub or bearing s near its.

lower end. and through which extends a spindle 2s. Mounted ontherear end of said spindle is a ratchet wheel is and engaging therewith is a pawl 48. Thepawl is pivotally carried by one end of a link 58, the other end of which is pivotally connected to one end of a link 6s, the other end of which in turn is pivotally connected to an. upstanding bifurcated lug ls mounted on the base plate C. Th pawl 4s is held in engagement with the ratchet wheel by a tension spring 83. Mounted upon the forwardly extending end of the spindle 2s is'a cushion roller T. A friction roller T mounted upon a link V pivotally connected to the depending bracket S is held in frictional pressing engagement with the periphery of said roller T by means of a spring U, one end of which is connected to the free end of the link V and the other end of which is connected to the bracket S.

The cushioning strip 1' after being guidedv through the channel 5h in the platen and. under the deflecting lip 93h passes through the friction rollers T and T; the associated pawl and ratchet mechanism of which serves to draw said. strip through therollers everytime the platen completes an upward and downward movement in performing a stamping operation.

In the operation of our press a sheet of stationery or the like W which is to be operated upon by the stamping and perforating dies is engaged under the clips k on the platen after the guide K has been set. In the instant case a sheet of stationery has an area 112 of contrasting color to the sheet and the guide K is set so as to bring this area w directly under the stamping dies. Now let ussuppose that it is desired to ornament said paper sheet with the cut out arbitrary initials EFA and to encompass said initials in a border 219' of contrasting color to both the paper and the area to; More specifically let us suppose that the paper is white, the area '11) is red and the border 2w is gold so that the cut out initials will be: red surrounded by a border of gold. The stamping and perforating initial dies EFA with spacing elements therebetween will first be mounted in. the chase F and thechase then mounted in. the palette E. The color strip m will be such. as adapted to deposit upon the paper a gold coloration when heat and pressure is applied thereto. The individual initial and spacing dies are of the character morespecifically shown .in detail in Figs. 6 to 8.

The initial dies X and spacer dies Y have cutting means a: and g respectively which are adapted to cut through or perforate the paper to leave the initials EFAfstand out. in relief- The top 2 of the chase is of less height than the cutting means a: and y but of greater height than the clearance or depth of said cutting means so that the top of the chase provides a a ioning strip therefore under the influence of heat and stamping pressure upon the chase will embed the cut out or scrap portions from the sheet W' and the color strip m in the surface of the cushioning stripwhich will carry said scrap portions away as freshportions of thecolor and 01' the cushioning strips are presented to the dies for each stamping operation. It will 7 be apparent that such fresh portions of both the color strip and the cushioning strip will be presented to the stamping dies after each stamping operation because of the feed action of the. ratchets O and 3s respectively. g V V I It will be apparent that any color scheme of contrasting colors for the ornamentation of stationery and the like can be provided by our invention by varying the contrasting colors of the paper and color stripsemployed and it will be also apparent that the color strip may be used with ordinary stamping or printing dies or type and that cutting dies may be used without or independently of any color strip. It will also be apparent that the invention is susceptible of embodiment in other forms than herein specifically illustrated and we therefore do not wish to be limited to the details of construction shown and described since the-same may be changed without departing. from the spirit of the invention as expressed in appended claims...
