Oct. 13, 1953 H. c. RICKENBACH STAMP HOLDER FOR EMBOSSING DIES Filed July '7, 1950 UUUUUUUC U INVENTOR. WC, My 71 Patented Oct. 13, 1953 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to holders for marking stamps of the type which are struck a blow at the top, and it is among the objects thereof to provide a holder adapted to receive a multiple 'of marking stamps which shall provide positive vertical alignment of the stamps, prevent wobbling thereof at the center, and be of relatively light weight which is essential in holders carrying a large number of stamps for marking products in steel plants and the like.

It is a further object of the invention to provide a holder for stamping dies having spring means for holding the stamps in the holder and in which the springs are connected by a wire to prevent their becoming loose.

It is a further object of the invention to provide such a holder of aluminum with a solid steel handle which prevents breakage in use.

It is still a further object of the invention to provide a die holder in which the main body portion is of rolled bar aluminum and is provided with a top plate of steel for receiving glancing hammer blows, the composite structure being of relatively light weight compared to prior art holders made of all steel.

The invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts, and in which:

Fig. 1 is a side elevational view of a holder embodying the principles of this invention;

Fig. 2 a top plan view thereof with the handle portion partially cut away and with the cover plate removed;

Fig. 3 a vertical cross-sectional view of the holder shown in Fig. 1;

Fig. 4 a transverse section taken along the line 44, Fig. 2; and

Fig. 5 a front elevation of a fragmentary portion of a composite die holder showing a modified form of attaching the cover plate to the body of the holder.

With reference to the several figures of the drawing, numeral l designates the die holder body made of rolled bar aluminum and having rectangular openings 2 for receiving the stamping dies 3 which are of similar shape, the openings 2 being larger than the bodies of the stamps 3 to eliminate binding. A longitudinal slot 4 is provided adjacent the rectangular openings 2, as shown in Fig. 2, and the body of the die extends in one direction to provide an enlarged area for a rectangular opening 5 that receives a larger stamping die such as the stamp 6 of Fig. 1.

A steel handle 1 is attached to the holder 'l' by placing it through a vertical opening 8 and fastening it by a rivet or screw 9 extending through the body I and through the steel handle as shown in dotted lines in Fig. 2.

Disposed within the rectangular openings 2 of the holder I are fiat springs I0, more clearly shown in Fig. 4 of the drawing, having eyelets I! for receiving a wire or rod 12 that extends through all of the eyelets and into portions of slot 4 that extend beyond the opening 2 as shown in Fig. 2. In this manner the springs are simultaneously assembled by dropping them into the slot 4 of the block or holder I. A retaining cover of steel, designated by the numeral I4, is placed upon the holder I to retain the springs and wire and is secured thereto by screws 1 5 in the manner shown in Fig. 1, or the cover may have an overlapping flange I6, Fig. 5, for receiving screws I! at the side instead of the top of the cover It.

The cover piece I 4 is provided with rectangular openings [8 of a smaller area than the openings 2 of the aluminum block I. This is more clearly shown in Fig. 4. of the drawings. Openings I 8 are of a size to provide clearance for the stamps 3 which have a loose sliding fit in the openings [8 and ample clearance in the opening 2 of the block I to prevent binding. The cover piece I 4 is of a sufiicient thickness to provide enough depth area for the stamps 3 to maintain proper alignment of the rows of stamps. The opening in the cover piece for the large stamp 6 is smaller than the opening 5, Fig. 2, to receive the stamp 6 and maintain its alignment. The springs l0 provide sufficient grip to retain the stamps in the stamp block for handling purposes.

As shown in Figs. 1 and 3, feet H! are provided on which the block I rests when in use. These feet may be square headed screws placed in tapped holes of the block I, as is clearly shown in the drawing. The screws are adjusted to the distance the ends of the dies should protrude below the die holder to provide proper working clearance to assure contact of the face of the die with the work before the impact blow is applied at the top of the die.

By the use of the composite aluminum and steel stamp holder, a light weight, durable holder is provided by which a multiple of stamps can be used with facility. Also by utilizing a steel handle member I, sufiicient strength is provided to avoid fatigue and breakage of the handle at the joint. It must be remembered that these die holders are subjected to glancing blows when in use, which may include blows on the handle portion 7. The die holder with the charge of dies is placed on a surface to be stamped, such as steel tubes or other steel products, and each stamp is individually struck by a hammer blow to impart a series of legends on the stamped article.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. A stamp holder having a body portion with a plurality of longitudinally spaced rectangular openings and having a cover plate with openings in register with the openings of the holder, said holder and plate being adapted to receive stamps with their axes in vertical alignment, said holder having leaf springs extending a substantial distance into the rectangular openings for grippingly engaging the body of the stamps, said springs having eyelets at one end and a rod extending through said eyelets whereby they can be simultaneously inserted in the stamp holder between the body of the holder and the cover plate.

2. In a stamp holder, 2. base having a plurality of rectangular shaped slots extending vertically from the bottom of the holder and being arranged in spaced relation axially of said holder, said holder having a shoulder on one side at the top of the rectangular slots, leaf springs having eyelets and a rod which is disposed in the shoulder portions of the holder extending through said eyelets whereby said springs can be simultaneously inserted in the rectangular shaped slots, the body of the springs extending downwardly against one wall of the rectangular slots, and a cover plate for said holder for retaining said springs and rod having rectangular openings in register with the openings of the base for receiving stamping dies, the openings of the cover being of a smaller dimension than the slotted openings of the base to maintain working alignment of the stamp dies relative to each other and in said holder.
