Abstract
An embossing press designed to enable embossing, for example, a sender's name and address in customary reading location respectively separately selectively on letter writing paper sheets and on envelop flaps is provided with unique die plate carrying means enabling easy removal of the opposed die holders each with its individual die plate and replacement of them in horizontally reversed position. Each of the die plates is mounted in the terminal slot in its respective spring leaf or arm of a double-armed spring die holders carrier, both arms of which are joined at their inner end integrally to a yoke, by means of which the spring die holders carrier is attached rigidly firmly yet removably (when needed) to the supporting base of the press.
Claims23
An embossing press for use on embossable sheet material and having an embossing or forward end, comprising
- (a) a unitary base frame having as integral parts thereof (i) a floor having integral front and rear portions, said front portion including
- (b) means for supporting a die-holder thereon at said embossing end and, (ii) upwardly extending from said floor at a position rearward of said embossing end and thence forwardly to a position over said embossing end a lever-supporting portion, provided with means for pivotally supporting thereon the anchoring end of an operating lever;
- (c) an operating lever having an anchoring end and being pivotally supported at said end,
- (d) a lower die-holder having a support back supported thereon and in stationary position on said die-holder supporting means therefor,
- (e) a spring arm having a free end near said forward end and a fixed end, said spring arm
- (i) serving to support at its free end an upper die-holder also having a support back and spaced above said lower die-holder and in a position to enable said upper die-holder to be moved with that free end toward and away from said lower die-holder, whereby by such movement of the upper die-holder toward said lower die-holder their respective opposed faces are brought into mating registry during embossing operation, and
- (ii) having anchoring means as an unitarily integral part thereof at the fixed end;
- (f) said frame floor having as a unitarily integral part thereof and extending directly upwardly therefrom a spring arm-anchoring means holding part, to which holding part there is fixedly yet removably anchored said spring arm-anchoring means;
- (g) said spring-arm anchoring means being so designed as to friction-fittingly fixedly yet removably anchor the spring arm to said anchoring means holding part;
- and
- (h) said operating lever having a pressure-transmitting member depending therefrom at said embossing end and rearward of said pivotal support means, said member being so positioned to be brought into pressure-transmitting contact with the top surface of said upper die-holder, whereby manual downward force applied to the top surface of said operating lever at a locus behind said member will cause said lever to pivot on said pivotal support means impelling said upper die-holder to move downwardly toward said lower die-holder thereby effecting mating engagement between their opposed faces for embossing sheet material placed between said faces;
- said spring arm being flat and bifurcated at its free end and thus being provided with adjacent spaced apart spring fingers bounding an open-ended longitudinal slot as means for supporting said upper die-holder, said upper die-holder having on its top securing means enabling the die-holder to be fixedly but removably engaged by the bifurcated end of the spring arm.

An embossing press for use on embossable sheet material and having an embossing or forward end, said press comprising
- (a) a unitary base frame having as integral holding parts thereof
- (i) a floor having integral front and rear portions, said front portion including means for supporting a die-holder thereon at said embossing end, and
- (ii) upwardly extending from said rear portion of said floor at a location rearward of said embossing end and thence forwardly to a position over said embossing end a lever supporting portion provided with means for pivotally supporting thereon the anchoring end of an operating lever;
- and
- (b) an operating lever having an anchoring end and being pivotally supported at said end by said lever-supporting portion,
- (c) a lower die-holder supported in stationary position on said die-holder supporting means,
- (d) a spring arm having a free end near said embossing end and also a fixed end remote from said free end, said spring arm
- (i) serving to support at its free end an upper die-holder above said lower die-holder and in a position to enable said upper die-holder to be moved with that free end toward and away from said lower die-holder, whereby by such movement of the upper die-holder toward said lower die-holder their respective opposed faces are brought into mating registry during embossing operation;
- and
- (ii) having anchoring means as a unitarily integral part thereof at its fixed end;
- and
- (iii) said frame floor having as a unitarily integral part thereof and extending directly upwardly therefrom a spring arm-anchoring means holding part in the shape of an upturned tongue, and the spring arm-anchoring means is yoke-shaped like an inverted U having its base at the top and having downwardly extending front and rear legs respectively depending from opposite ends of the base, both of the legs being relatively narrow parallel walls which are pushed down over the up-turned tongue and so spaced apart from one another that the yoke is fixedly held in friction-tight engagement with said tongue and yet removably anchored thereto.

An embossing press for use on embossable sheet material and having an embossing or forward end, comprising
- (a) a unitary base frame having as integral parts thereof (i) a floor having integral front and rear portions, said front portion including means for supporting a first die-holder thereon at said embossing end, and
- (ii) upwardly extending from said floor at a position rearward of said embossing end and thence forwardly to a position over said embossing end a lever-supporting portion provided with means for pivotally supporting thereon the anchoring end of an operating lever.
- (b) an operating lever pivotally supported at its said anchoring end,
- (c) a spring arm having a free end near said forward end and a fixed end, said spring arm
- (i) serving to support at its free end a second die-holder in a position to enable said second die-holder to be moved with that free end toward and away from said first die-holder, and
- (ii) having anchoring means at its fixed end and being flat and bifurcated at its free end, thus being provided with adjacent spaced apart spring fingers bounding an open-ended longitudinal slot for supporting said second die-holder, said second die-holder having on its upper face securing means cooperating with said slot and enabling said die-holder to be fixedly yet removably attached to said spring fingers;
- and
- (iii) further including die-holder restraining means depending from the outer end of each of the spring fingers and snugly engaging the front of the second die-holder and thereby restraining said die-holder against forward movement during embossing, yet, due to the springiness of the fingers, permitting that die-holder to be removed from engagement with the spring fingers upon applying an outwardly directed force on the die-holder.
