To all whom it may wurm:

Be it known that I, HENRY S. lvIArDnoF, a citizen of the United States, and resident of the borough of the Bronx, in the city and State of New York, have invented anew and useful Improvement in Seal-Presses, of which the following is a specification.

The objects of this invention are to provide certain improvements in a seal press whereby the press may be readily convertedior use either for impressing seals or for embossing paper as may be desired.

A practical embodiment of the invention is represented in the accompanying drawings in which- Figure 1 represents the seal press in fronty elevation, Fig. 2 is a view of the' same in side elevation, the parts being shown in full lines in their raised position and in dotted lines in their depressed position. Fig. 3 is a detail section taken in the plane ofthe line A-A of Fig. 2 looking in the direction of the arrows. Fig. 4 is a detail section taken in the plane of the line B-B of Fig. 1, looking in the direction of the arrows. Fig. 5 isa transverse section taken in the plane of the line C-C of Fig. 2, Fig. 6 is an inverted planl view of the die; Fig. 7 is a detail view of the locking pin for the die, and Fig. 8 is a detail side view of the removable platen.

The base of the seal is denoted by 1 and the arm by 2. The die plunger 3 is iitted to reciprocate vertically in the arm 2. The plunger is guided in its reciprocating movements by means of a transverse pin 4 which extends laterally through elongated slots 5, 6, in the sides of the arm 2. This pin 2 is shown herein as being secured in position by the central screw 7 of the die supporting plate 8. The die 9 is detachably secured to the plunger plate 8 as follows. The die 9 has a sliding dovetail connection with the plate 8 of the plunger by providing the back of the die with a tongue 10 arranged to slide laterally into an open-ended groove 11 in the plate 8. The die is detachably secured inl position on the late 8 between a iixed pin 12 and a removable locking pin 13. The locking pin 13, when in position, extendsdownwardly through a hole 14 in the plate 8 and a hole 15 in the die 9. After the die supporting plate 8 of the plunger has been screwed into engagement with the plunger, a second screw 7* is screwed through one of a series of holes 8* in the plate 8 into the bottom of the plunger 3 :for leeliiee the plate 8 rigidly to the plunger 3.

`The platee l@ is .removably secured in P0- .Si..0r1` en te. has@ 1 by' nrevdire' the bask of the platee with depending lues' 17 arranged to enter holes 18 in the said base.

The hand lever of the press is denoted by 19 and its pivot by 20. This hand lever is provided with the usual cam 21 for engaging the top of the die plunger 3 for depressing the same. The means which I have shown for normally holding the die plunger'at the limit of its upward movement comprises two coil springs 22, 23, located exterior to the arm 2 and connected at their lower ends to the pin 4 and at their upper ends to extensions 24, 25, of the pivot 20.

In the construction of press herein shown it will be seen that platens may be readily removed and inserted. Furthermore it will be seen that the dies may be also readily removed and inserted. When it is desired to replace the die, the locking pin 13 is removed from its engagement with the die, thus permitting the die to be slid laterally out of its interlocking engagement with the plunger plate 8. After another die has been inserted into position the locking pin 13 may be dropped into its position to lock the die to the plunger. The plunger is held absolutely againstv any turning movement during its reciprocations by the pin and slot connection between the plunger and the walls ofthe arm 2. Also a much stronger construction can be obtained by the location of the plunger retraoting s rings exterior to the arm.

What I cl3aim is:

1. A seal press including a die plunger, an arm in which it is fitted to reciprocate, a hand lever for depressing the plunger, a pivot passing through said lever and said arrn and springs engaging said pivot located upon opposite sides of the arm for normally holding the plunger in its raised position.

2. A seal press, an arm, a vertically reciprocating die plunger having a pin and slot connection with said arm, a hand lever for depressing the plunger, a pivot passing through said lever and said arm and springs engaging said pivot exterior to the arm i'or normally holding the plunger raised.

3. In aseal press, an arm having elongated slots therein, a plunger fitted to reciprocate in the arm, a pin carried by the plunger guided in said slots, a hand lever for depressing the plunger and springs exterior to the arm engaging the ends of the said pin for normally holding the plunger in its raised position.

4. A seal press, including a die plunger, a die detachably secured thereto, an arm in which the plunger is fitted to reciprocate, a hand lever Afor depressing the plunger, a pivot passing through said lever and said arm, and springs engaging said pivot located upon opposite sides of the arm 'for normally holding the plunger in its raised osition.

5. A seal press, inclu ing a die plunger, a die supporting plate carried thereby, a die detachably secured to said plate, an arm in which the plunger is litted to reciprocate, a hand lever for depressing the plunger, a pivot passing through said lever and said arm, and springs engaging said pivot located upon opposite sides oi the arm for normalli` holding the plunger in its raised position.

In testimony, that l claim the 'foregoing as my invention, have signed my name iii presence of' two Witnesses, this 29th day ol' March 1907.
