kTheconnection 13 between the impression ldie 11 and the operating lever 12 consists of a rocker 32 which occupies a slot 33 found inthe upper portion of the ram 22and protrudes from the kslot at both ends of the same; One protruding end ofthe rocker is pivotally mounted on the upper aw portion of the "frame by means of a pin 34-which passes through aligned apertures in the side walls; the other oppositelyprotruding end of the rocker is Ytapered and presents an inclined surface 35 for coaction with the cam roller 31;r the medial bottom portion of the rocker is downwardly convex and presents a segmental bearing surface 36 for the rocker against a flat thrust surface 37 of the ram; and the medial upper portion of the rocker is upwardly convex and presents a segmen- Y tal bearing surface 38 for coaction with two inwardly overlapping lips 39 on the .top of the ram. A compressed spring 40 is housed withinthe frame and engages with the rocker at a point below the point of engagement of the cam roller in order to normally maintain the free endv of the rocker in its elevated position. l v

The impression bed 14 includes a flash plate'41 and an equalizing plate 42. The flash plate is circular in shape, and is provided with a depending skirt 43 which is cut away at diametrically opposed points in korder to permit the flash plate to straddle the lower jaw portion 17 of the frame without directly -contacting with the same. The

remaining uncut portions of the skirt 43 constitute spaced supports 44 on opposite sides of the frame for use 1n conjunction with the terminal support 20 when it is desired to rest the seal-press upon a plane surface. The Lipper surface of the flash plate is adapted to be coated in the usual manner with a composition y4,5 on which is presented a seal inscription complementary to that presented on the under face of the die head 21. The

, equalizing plate iscircular in shape, and is posed segmental projection 46 and two or more pairs of studs 47 are formed inther They under face of the equalizing plate. segmental projectionris adapted to seat at its opposite` ends in transversely aligned complementary notches in the upper surface ofthe lower jaw portion of the frame with 48. The upper end of the anchor ybolt passes upwardly through an aperture in the segmental projection on the equalizing plate and is Vprovided above the loosely encompassing aperture with a segmental head 49 which seats in the depression resulting from the pressed formation of the segmental projection, and the lower end of the anchor bolt passes downwardly to a threaded conical aperture in the bottom of the lower aw vportion and is engaged by an exteriorly threaded split conical nut 50 which is in turn engaged with the aperture in the -jaw portion. The nut is screwed up tightly upon the anchor bolt, and serves to'hold the iinpression bed firmly down upon the lower jaw portion of the frame while permitting with friction a slight readjustingV movement of the impression bed relativeto the lowerejaw portion upon movement of the die head into compressive engagement with the upper lsurface of the flash plate. The split conical nut is wedged between the bolt andthe encompassing aperture in the jaw portion, and the wedged action results in a frictionall constriction of the nut on the bolt serving to.

prevent the impression bed fromV working loose on its anchorage.

VThe pivoting pins 29 and referred to in connection with the detailed description of they operating lever 12l and the connection 13, are provided,vinter1nediate their ends, with annular grooves 51. A curved cover plate 52 of spring material spans the gap between the front and top Vedges of the side walls ofthe upper jaw port-ion of the frame, and is provided, at

its ends, with laterally reduced tongues 53 which curve'about the pivoting pins and seat in the annular grooves of ythe same; The cover plate is also provided, at opposite points along its side edges, with two downwardly bent clips 54 which seat in recesses in the side walls of the upper jaw portion and serve to position the cover plate relative to the side walls.

The lugs 26 and the studs 47, which werel referred to in connection with the detailed description of the impression die 11 andthe 34, which wereV ioo Y Eagle593@ impression lhedl Alet, arev preferably die; punched formationsk wherein the. metaly Ywithin:certain areas onY the opposite sidesr` of the sheet ,of metal :is caused to'` flow uncle-rf p13'assurerV into C project-ions of less:k area.. These formations are economical to produce' and are extremely durable.
