HAND STAMP Filed March 5, 1935 Patented Fel). 9, 1937 A srArss ATENT OFICE 7 Claims.

My invention relates to hand stamps of the dater type, and has for its object improvements in such devices.

In the accompanying drawing:

Fig. l is a central longitudinal section, at about full size and partly in elevation, of a hand stamp made in accordance with my invention;

Fig. 2 is a transverse section, partly in elevation, on line 2 2 of Fig. l;

Fig. 3 is a section on line 3--3 of Fig. 1;

Fig. 4 is a section of the stamp frame and die holder with the dater element in the process of being inserted or withdrawn;

Fig. 5 is a perspective view of the yoke which embraces and holds the dater element; and

Fig. 6 is a plan of the stamp frame.

To the die-holding plate III is secured a stamp frame consisting of legs ii and connecting bridge I2, formed from a single piece of metal. The distance between the legs II is just suiilcient to receive the dater element having legs I3 and shaft Ill. The dater element is the same as that in common use except that the bend in the legs at I5 is a little sharper and more pronounced than usual.

The yoke for receiving and holding the dater element consists of legs I6 connected by a bridge I1, and is made of spring metal. In the legs I6 are rectangular openings I8 of a size just sufficient to receive those parts of legs I3 which are above the bends I 5. The parts I9 of the yoke come just below the bends I5 and serve to hold the dater element rmly within the yoke.

The dater element is inserted or removed from the yoke by manually bending the spring legs I6 outward.

Riveted to the center of the bridge I'I is a screw 2|), and in the bridge I 2 is a recess 2I arranged to receive the screw 20 when the dater element is in proper position in the frame. The die-holding element I0 has the ordinary central opening thru which the dater element projects to match a die held in the plate.

On the screw 2li are nuts 22 and 23 arranged to engage the upper and lower faces of bridge I2 when said screw is in the recess 2|. It will be evident that by turning the nuts 22 and 23, the dater element may be adjusted vertically to make the characters on the bands ofthe dater come even with whatever characters may be on a die 2l] held in the plate I0. When properly adjusted the two nuts serve as a means for locking the dater in position.

A cap 24 ts over the upper part of the stamp frame and encloses the nuts 22 and 23. A handle (Cl. lill-111) 25 is screwed on the upper end of the screw 2@ and serves to hold the cap in position.

The central part of the cap 24, thru which the screw 2li passes, is stamped to form a recess on the inside to receive the nut 23, and this forms 5 a projecting bearing surface 2'! on` the upper side against which the handle 25 is screwed. The recess below is of less depth than the thickness of the nut 23 with the result that when the handle is screwed down, it clamps the cap 24% on said 10 nut and thus furnishes a secondary lock for securing the dater element from displacement in the frame.

The manner of inserting the dater element in the yoke has already been described. The man 15 ner of inserting the yoke and dater element in the stamp frame is illustrated in Fig. 4, and will be understood without special description. The assembled condition is shown in Figs. 1 and 2.

It is to be noticed that the yoke has the screw 2li secured thereto, and that the dater element is held within the yoke by the spring action of the metal from which the yoke is formed. As thus made, the yoke, dater and screw taken together constitute a self-contained dater unit which may 25 be inserted in or withdrawn from the stamp frame, and this is true whether the nuts 22 and 23 are on the screw or not. In the same way we may say that the frame and die holder are a unit because they are permanently secured 30 together.

I-Ieretofore it has been the practice to raise and lower the dater element with respect to the die element by means of screws and springs properly housed and located over the die holder 35 and at each end of the dater element. Such constructions are relatively expensive to make, are cumbersome in appearance, are not easily adjustable because the adjustments are at two places and must agree, are liable to displace- 40 ment` and are places for catching dirt.

In the present case, the screw used for holding the handle of the stamp is utilized for all adjustments, and the adjustments are at one place instead of being at two places. When an adjustment is made it is locked in position by the nuts making the adjustment, and the adjusting devices are completely enclosed by a cap held in place by the handle. There are no screws at any place other than the one for the handle, which screw is here used for a double purpose.

What I claim is:

1. In a hand stamp, a yoke of spring metal having openings in its legs, a dater element within the yoke and having the upper portions of its legs tting into the openings in the legs of the yoke, a die holder, a stamp frame secured to the holder and enclosing the yoke, and means associated with the upper part of the stamp frame for adjusting the elevation of the dater element with respect to a die held in the die holder.

2. A hand stamp providing a main frame, a die plate and a die having a dater Aelement therein, a spring yoke within which the dater element is inserted and by which it is held by spring action, and means by which the yoke and the dater element therein are vertically adjusted with respect to the said other parts of the stamp.

3. In a hand stamp, a unit consisting of a frame and a die holder rigidly secured together, and a dater unit with adjusting means, said dater unit with its adjusting means being freely inserted in and withdrawn from the frame unit.

4. In a hand stamp, a frame and a die holder, a dater element within the frame, means for adjusting the dater element vertically in the frame, and a cap enclosing the adjusting means.

5. In a hand stamp, a die holder with a central opening for the insertion of dating devices,

a frame secured to the holder and having a recess in one side over the center of the opening in the holder, a dater unit having a screw carried thereby and projecting upward from its center, and nuts on said screw, said dater unit with screw and nuts being insertable between the sides of the frame with its lower part projecting thru the opening in the holder and the screw in the recess and said nuts engaging the frame adjacent to the recess to adjust the dater unit in the frame.

6. In a hand stamp, a frame and a die holder, a dater element, means for adjusting the dater element in the frame, a handle for the stamp, and means by which the handle serves as a lock for the adjusting means.

'7. In a hand stamp, a unit consisting of a frame and a die holder rigidly secured together, and a dater element having a screw and adjusting nuts, the die holder having a central opening and the frame having a lateral recess over said opening whereby the dater element may be inserted in the frame by lateral and vertical movements with respect to said opening and said recess.
