SEAL-PRESS.

SPECIFICATION forming part of Letters Patent No. 569,742, dated October 20, 1896.

Application filed August 12, 1896. Serial him-602,574. (No model.

"To aZZ whom it may concern.

Be it known that I, EDWARD J. BnooKs, a citizen of the United States of America, and a resident of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Seal-Presses, of which the fol.- lowing is a specification.

This invention is additional to my improvements in seal-presses patented May 6, 1884, No. 298,284; September 22, 1885, No. 326,897; October 13, 1885, No. 328,106; October 14, 1890, No. 4138140, and November 1, 1892, No. 485,370. The object of the present improvement, in common with said patented improvements, is to insure securely fastening and distinctly stamping each seal, and to this end each press is provided with a ratchet attachment which prevents reopening the leverhandles of the press after the pressing operation is begun until the press has been closed to the predetermined extent neccssaryto perfectly compress the seal.

The present invention consists in a novel combination of peculiarly arranged parts whereby a simple and efiective form of sealpress, known as the hammer press, is for the first time adapted to so operate, and the ratchet attachment is simplified and more fully incorporated in portions of the press which are otherwise essential, so as to lessen the number of parts.

The invention further consists in a specific combination and arrangement of parts Whereby the ratchet-rack is carried by and may be conveniently cast in one of the checks of the customary head, simply extended or enlarged for this purpose.

A sheet of drawings accompanies this speciiication. as part thereof.

Figure 1 is a top view of my improved sealpress opened. Fig. 2 is a longitudinal section of the same. Fig. 3 is a side elevation of the head portion of the same press closed. Fig. 4: is a view from the opposite side of its pawl-carrying lever-handle detached. Fig. 5 is a crosssection on the line 5 5, Fig. 4, partly in elevation. Fig. 6 is an elevation on a reduced scale of a modified seal-press open. Fig. 7 is a view of its rack-carrying lever-handle projected from Fig. 6, showing its pawl and pawlspring in juxtaposition. Fig. 8 is a top or end View of said modified seal-press, Figs. (3 and 7, closed, on the same scale as Figs. 1 to 5, inclusive; and Fig. 9 is a view similar to Fig. 8, showing an additional modification.

Like letters and numbers refer to like parts in all the figures.

The improved seal-press in either of its forms is composed principally of two main parts A and 13, having lever-handles a b integral therewith, a head c on said main part A containing a reciprocating die (Z, and preferably a bed-die c to coact therewith, and a fulcrum-pin f, which unites the two main parts. A spring g, Fig. 2, attached by ascre w h to the casting of the main part A, renders the die d normally retracted, and a cam'i, eccentric to said fulcrum-pin f at theextremity of the main part B, coacts with said die to fasten and stamp the seal by compression.

To insure fully closing the press at each pressing operation, and thus to insure securely-fastened and legibly-stampe'd seals without any very great or expensive departure from the pattern of this popular form of press, one or each of the checks 1 and 2 of the head of the press is suitably extended or en larged, and the cam-carrying main part has a suitable enlargement 3, and they are provided, respectively, with a ratchet-rack concentric with said fulcrum-pinf, and apawl 79 in mesh with said rack, said rack having reversing recesses a and 5 at its ends, and said pawl being accompanied by a pin 6, radial to said fulcrum-pin, upon which the pawl is free to turn, and a spring 7, with or without a follower 8, Figs. 4 and 5, within the recess 9, which incloses or partly incloses the pawl, to hold said pawl normally in edective position.

The bed-die c is preferably and conveniently formed with a stop-flange s to locate the seal between the dies within the mouth mof the seal-press, and is fastened in place in customary manner by a screw .9. The customary hammer-face 7?. is formed on the head 0 in line with the dies at and e. A recess (shown at r in Fig. 2) accommodates a core-support in the operation of casting the main part A. These details are common to the presses shown in the drawings and are preferred details of mechanical construction, but form no part of the present invention.

In the species represented by 1 to 5, inclusive, the ratchet-rack j, with its recesses 4t and 5, is formed in the inner side of the check 1, which is extended or enlarged edgewise relative to the check 2, as shown in Fig. 1. Thus located the rack, with its recesses, may be conveniently formed in the act of casting the main part A, and both pawl and ratchet may be as large as may be required for strength and durability. \Vith the rack so arranged the stroke-controlling pawl 7. with its pivot 6, spring 7, and follower S, is located within a recess 0 and a drill-hole crossing the same in said enlargement 3 of the main part B, as found in this press.

In the species represented by Figs. (3, 7, and S the ratehet-rackj, with its recesses at and 5, is formed by an attachment to said enlargement 3 of the main casting B, as found in this press, held in place within a recess in one side of said enlargement by a countersunk screw 5 and the stroke-controlling pawl 7t with its pivot-pin 6 and spring '7 are carried by the main part A within suitable recesses and drill holes in the laterally-enlarged check 2 of the head 0.

Either arrangement of the pawl and ratchet may be duplicated, represented in Fig. 9, which shows a duplication of the arrangement last described.

Each of the springs 7 above described may be fastened in place by means of a screw or rivet, or in any preferred manner, or in a suitable shape may be left loose behind the pawl within the opening 9, which incloses the latter. Spiral springs may be substituted for the blade-springs shown at '7 in the drawings. Dies for fastening and stamping sheet-metal seals and seals of other forms may take the place of the lead seal-dies shown at (Z and e, and other like details and additional modifications will suggest themselves to those skilled in the art.

Having thus described the said improvement, I claim as my invention and desire to patent under this specification 1. In a seal-press composed principally of two main parts, having lever-handles integral therewith, a head on one of said parts containing a reciprocating die, and a fulcrum-pin which unites the two main parts, the combination of a check or checks forming part of said head and a suitable enlargement of the other main part, having respectively a springpressed pawl reversing on a pivot radial to said fulcrum-pin and a ratchet-rack concen trio with said fulcrum-pin and having revers ing recesses at its ends to coact with said pawl.

2. In a seal-press composed principally of two main parts, having lever-handles integral therewith, a head on one of said parts containing a reciprocating die, and a fulcrum-pin which unites the two main parts, the combination of a cheek forming part of said head and provided with a ratchet-rack concentric with said fulcrum-pin and a spring-pressed pawl carried by the other main part, reversing on a pivot radial to said fulcrum-pin, an d coactin g with said rack, substantially as hereinbefore specified.

E. J. BROOKS.
