SEAL-PRESS.

SPECIFICATION forming part of Letters Patent No. 542,035, dated July 2, 1895. Application filed February 28, 1895- $eria-1No. 540,110- (No model.)

To ctZZ whom it may concern:

Be it known that I, THOMAS D. WILLEVER, a citizen of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Seal-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same.

The invention relates to hand-operated sealpresses more especially designed for compressing metallic seals (usually of lead) commonly used upon freight-car doors, trunks,

expresspackages, dressed beef, &c. \Vith slight modifications the device may be appli-. cable to pliers, saw-sets, due.

The object of the invention is to provide a 0 seal-press of the class specified which shall be simple and effective in operation and at a cost of production comparatively economical.

The invention consists in .the device hereinafter described and finally set forth in the 2 claims, and further consists more particularly in the mannerof obtaining the necessary power to operate the press.

In the drawings accompanying this specification, Figure 1 is a plan view having aportion of the body or stock broken away in order to more clearly illustrate the construction. Fig. 2 is a top View, and Fig. 3 a detached view in detail of the toggle-lever and sliding die.

In the said drawings, Bis the body orstock of the press, which is made preferably of cast malleable iron. The said stock B is formed with a longitudinal bore and box or recess in the body thereof and the continuation of the 0 body forms a rigidhandle.

A is the actuating or lever handle which is pivoted at its forward end to the stockJB and swings in a plane therewith. The said leverhandle A operates a movable or sliding die at through the medium of a toggle-lever b a, connected to the said lever-handle by a link a at the joint of the toggle-lever. The rearward member I) of the toggle is pivoted to the stock B, and the forward member 0 is pivoted to the sliding die 61 at a bifurcation on the rear end thereof, as more clearly seen in the detached view in Fig. 3. An adjustable stationary anvil or die 8, externally screw-threaded, is secured in the tubular bore (the latter being internally threaded). This permits a limited adjustment of the same in its axial line, as will be understood.

A fiat springfis riveted to the stock and normally acts to keep the handles of the sealpress open (asseen in Fig. 1) by upward 6o pressure upon the toggle-lever. The togglelever and lever-handle are so fitted that the strain or pressure shall be borne by a cam 9, formed on the said handle, rather than by the pivotally-connecting link athat is to say, the cam g and apex of the toggle are in close frictional contact during the process of press ing a seal. I

The operation is to insert the blank sealdisk laterally or sidewise between the sta- '70 tionary and movable dies and d and compress or stamp the same by pressing the two handles together, as will be'understood. The blank-lead seal which holds the wire shackle is more or less porous and soft before compression. As its compression takes place it becomes much harder and offers greater resistance to the dies. When this resistance increases, the power of the seal-press increases in proportion-that is to say, when the greatest pressure is required the toggle-lever is almost in a straight line.

Having described the invention, what I claim is as follows:

1. A seal press comprising abody or stock 8 having a rigid handle thereon, a swinging lever handle pivoted to said stock, a toggle-lever, a link connecting said toggle-lever and lever-handle, a sliding die pivoted to'said toggle-lever and a stationary die in said stock go all arranged substantially as described.

2. A hand seal press comprising the combination of a body or stock having a longitudinal bore, a recessed side and a rigid handle with a swinging lever-handle pivoted to said 5 stock and having a cam thereon, a toggle-lever pivoted to the stock, a sliding die pivoted to the said toggle-lever, a link' connecting the lever-handle and toggle at the joint of the latter and an adjustable stationary die sub- [co stantially as specified.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.

THOMAS D. WVILLEVER.
