' SEAL PRESS.

Application filed July 2, 1923, Serial No. 648,910. Renewed July 11, 1927.

This invention relates to; presses through means of which paper or other material may be embossed between a pair of counterpart dies, and has for its object to provide an improved construction of the. frame or mounting for the relativelyfmovable mem-' bers of such a press.

It has heretofore been proposed to make the frame of a seal press'out of a blank of plate metal, inversely arched or bent upon itself in a manner to provide a connecting web at bottom, and two cheeks upstanding therefrom, slotted longitudinally to provide a paper receiving recess and jaws above andv below the recess; the jaws being spaced apart-- to receive the parts that carry'the mating dies and cam lever. But n utilizing this form of frame, in spite of the edgewise presentation of the plate-like cheeks to the stresses of embossing pressure and notwithstanding the presence of the strut-like web at the bottom, there has been found to be sufficient spring in the lower jaw orbed to impair registryof the dies; moreover, this method of .25supporting the lower dieiupon the bed has notfbeen satisfactory. p

, According to the present invention, a bed plate is'mounted upon and betweenthe cheek plates that form the lower jaw by anchor ing'it immovably at its 1 respective ends so that it constitutes an additional trusslng member, extending in the same general d1- rection as the bottom web, but spaced above the latter so that while the bottom'web acts as a compression member under the vertical deflecting'fstresses of embossing, the bed plate above it acts as tension member and greatly stiffens the whole structure; and them-in, order to properly sustain the bed plate vertically it is given a form that adapts the forward end of the plate to rest upon and to be sustained by the cheek plates of the bed portion of the frame, and to abut rearwardly against shoulders formed on said-cheek plates, while the remainder of the bed plate, extending rearwardly and snuglyfitting between the cheek plates, has its rear end rigidly anchored by means of a transverse pin j which draws the bed plates rigidly to the rear. The front endof the plate is anchored and locked against relative movement in any direction-by its said shoulders and by riveting lugs rising from the seating edges ofthe lower jaw or bed.

- In order that the present invention may same.

registry between the dies.

be fully understood, the preferred embodiment thereof is illustrated in the accompanying drawing, in which Figure l is. a vertical'longitudinal section of a press embodying the new frame conitruction and provided with a supporting ase.

Figure 2'is a rear end elevation of the" Figure 3 is a section of the same on the B5 line'3 ,3 of Figure l. p Figure l is a front elevation of the pres shown in Figures in section; and

Figure Sisaside elevation ofa press,: the construction of which is identical with that shown-in Figures 1 to 4, except that the supporting base is omitted and the bedis extended rearwardly to provide ahand hold. 1 represents a frame member 'formed'of a (5 plate metal blank'folded along its longitudinal middle portionto provide two upstand ing spaced oheeks,portions of the blank being slotted to subdivide the cheeks into bedlpor-f tion 1 and jaw portions 1 2,1'epresents a{ bed plate fittedb'e'tween the bed cheek por tions 1, as shown more clearly in; Figure 3, 1'

sired; and the main body ofthe bed plate being fitted snugly between the bed cheeks and extendedflrearwardly to a pin 3 which '95 not only draws the cheeks firmly against the plate 2 andimit'es the cheek plates and the V bed plate laterally as a rigid braced structure, but also .firrnly anchors the plate against longitudinal movement at 'a point in rear of the springing point of the jaws and thereby trusses the the bed, makes it very much more rigid, and maintains better As a further means for'firmly uniting the forward end of the bed plate to the bed cheeks of the frame, the cheeks are stamped with a pair of riveting lugs 1 upstanding from the seating edges 1 of the cheek portions, and passing through and headed in' the bed-plate in a l, 2, and 3, with the base I manner to firmly resist relative movement between the plate and the bed in any direction, and especially in the direction of the length of the plate, so that the plate can act as a tension member or strut in trussing the lower jaw or bed under the embossing pressure as explained.

To receive the pin 3, the rear end of the plate 2 is folded to provide an eye 2 and the folded end 2 extended to provide a reinforced table upon which to anchor the plate spring 5 which carries the movable embossing member l, the rear end of which is rigidly secured to the said reinforced bet plate 2 by means of screw 6 which passes through said spring and through the twofold thickness of the bed plate. A controlling lever 7 is fulcrumed in the frame at S in the usual manner, and carries the known arrangement of camming roller 9 coacting with the anvil 10 of the movable die member t.

A die press constructed as above described may be designed as a table press by providing it with a base 1.1 suitably secured thereto, as, for instance, by rivets 12 passing through the base and through the connecting web 1 of the frame, as shown in Figures 1 to 4; or the frame 1 otherwise constructed as described in connection with Figures 1 to 4, may be provided with an extension 1 that adapts it to serve as a hand hold, thereby adaptingthe press to serve as a so-called hand press.

I claim: p

1.. In a seal press, a frame comprising spaced cheek plates forming upper and lower jaws, and a bed plate immovably anchored at its ends to said cheek plates and resisting bending of said check plates in vertical planes.

2. In a seal press, a frame, comprising spaced cheek plates forming upper and lower jaws, a bed plate immovably anchored at its ends to said check plates and resisting bending of said cheek plates in vertical planes, and a movable die carrying member mounted on said bed plate.

3.In a. seal press, a frame, comprising spaced cheek plates forming upper and lower jaws, a bed plate immovably anchored at its ends to said cheek plates and resisting bending of said check plates in vertical planes, and a movable die carrying member mounted on the rear end of said bed plate and extending forwardly to present its die over the forward end thereof.

4. In a seal press, a frame comprising spaced cheeks united by a connecting web in a plane extending longitudinally and transversely of said cheek and thereby adapted to receive stresses of longitudinal compression from vertical bending stresses in the cheeks, and a' bed plate in a transverse plane spaced from the plane of the web firmly anchored at its ends on said cheeks, and receiving stresses of tension from said bending stresses.

5.
