T 0 all to 720m it may concern metal. two like blanksto constitute the sides of the press, subsequently giving the slight bends best adapting them for the purpose; employ a. helical spring for separating; the seal elements; provide a closuredoclr for the operating handle which automatically releases the same when the press is taken in hand in actuating position and a slight squeeze given thereto, and provide other improvements in details of construction.

In the drawings forming' part of this specification, Figure 1. is a side view of the seal press in its position of use, but showing' the actuating handle locked in place. Fig. 2 is a side sectional view mi: the same. Fig. 3 is anend view thereof. Fig. 1 is a detail view of the plunger. Fig. 5 is a top view of the press.

The main body of the press consists ot two side members 1, 2 preferably blanked out from sheet metal by the same die, but bent toward each other at 3 to :torm the handle portion 4:; the jaw section 5 being spaced more widely. Between these jaw sections 5 are fastened, by riveting or welding, two blocks 6 and 7. To the block 6 is attached the female die member 9 by means of a screw 10 descending through the block into a hub 8 formed on the member 9. This hub fits snugly in a hole 11 in the block in order to accurately center it, but at about half the depth of this hole the front end of the block is channeled, as at 12, in order that by releasing the screw and dropping the member 9 a little, it can then be drawn torward and away from the block.

The male die member 13 has a pin 14 fixed thereto. which slides freely in the block 7, the latter being recessed to slidably receive a head 15 with which the pin is provided. Between this head and the upper Specification of Letters Patent.

limit of the recess is a helical spring 16 by which the seal member 13 is drawn away from the seal member 9.

The actuating handle 17 is pivoted at 19 below the block 7, and is provided with a cam surface 20 which, by its engagement with the head 15 as the handle is drawn upward, forces the die member 13 into sealingengagement with the die member 9. To keep the die member 13 from turning; relative to the other die member, the head 15 is given a groove 21 which accurately fits the sides oi? the cam 20, as shown in Fig. 8; and to hold the handle 17 from descending below-a desired level, a lip 22 is formed close to the cam 20 at a point to meet the head 15 and thereby to hold the handle.

To look the handle in its closed position, a leaf spring 23 is provided at whose outer end is a hook 24 adapted to engage and lock the end of the handle. This spring is adapt-- ed normally to retain its hook out or"; reach of the handle-end, but by first dra ing the handle up to its limit and then pressing the spring toward t1 e same, the hook engages and locks the handle; but, as soon as the handle is again drawn slightly upward, the spring throws its hook out of reach of the handle-end and the latter opens at once.

The spring" 23 is fastened in place by beinggiven a bend 25 slightly more than a semi-circle in contour, adapted to be sprung upon the pin 26 fastened between the members l, the tail 27 thereof resting against a strip 29 by which the upper edges of the portions 4 are inclosed, and thereby holding the hook at the required distance from the handle-end.

The strip 29 is secured in place by eyes 30 at its ends penetrated by rivets 31 passing through the side members 4c, as shown in Fig. 2.

What I claim is:

1. A seal press comprising a body member, a block held thereby having a recess therein, a die member having a hub fitting said recess, and a screw passing through said block into said hub, the block having a channel to permit the die member to be withdrawn after the screw hasreleased it and its hub is partially removed from the recess.

2. A. seal press comprising a body memher, a block held thereby having a shouldered hole therein, a die member having a headed pin rigidvtherewith slidable in said hole, a helical spring about said pin between its head and the shoulder of said hole, and an operating member having a cam surface acting against said head, the latter being slotted to receive said cam surface and to be kept thereby from rotation. 3. A seal press comprising two separate body sections composed of sheet metal, two blocks fastened between the same, two die members each supported by one of said blocks, an operating handle for pressing one of said die members against the other, and a backing strip for closing, the space between the upper edges of the handle portion of said body sections, said strip having an eye at each end, and said handle portion having rivets passing through said eyes.

4. A seal press comprising a body portion, die members carried thereby, a pivoted operating handle for actuating one of the die members, a resilient engaging device carried by the bod portion normally out of reach, of the handle but yieldingly pressable into engagement therewith, whereby a pressure of the handle toward the body portion releases it from the engaging device.

5. A seal press comprising a body portion, die members carried thereby, a pivoted operating handle for actuating one of the die members, and a hooked member carried by the body portion normally out of reach of the end of said handle but yieldingly pl'essable into engagement with. said end, whereby a slight movement of said handle toward the body portion releases it from said hook.

6. A seal press comprising two spaced body members, die members carried thereby, an operating handle pivoted between said body members for actuating one of thc die members, resilient means pressing the die members apart and swinirii'ig the handle downward, and a hooked spring held be tween said body members having its hook normally out of reach of the end of said handle but capable of being pressed into engagement with said end.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 5th day of August, 1921.

HAROLD HELLBERG.
