ABSTRACT:
This invention relates to stamps for forming images on a surface of a workpiece and more particularly to stamps for applying ink to the surface of the workpiece to create the image.
Stamps for forming an image from ink on a surface of a workpiece have heretofore been provided. Such stamps typically include a handle or stamp mount made from a substantially rigid material and an embossing member made from a suitable flexible material such as rubber secured to the stamp mount. The stamp mount is usually formed with a substantially planar bottom surface to which the embossing member is secured. A layer of an elastomeric material such as foamed rubber is sometimes disposed between the bottom surface of the stamp mount and the embossing member for facilitating the formation of the image on an irregular surface. Unfortunately, the stamp mount and the embossing member are usually secured together, directly or indirectly, in a permanent manner. An adhesive is often used in this regard. This permanent bond can result in tears in the embossing member when one attempts to remove the embossing member from the stamp mount. As a result of the foregoing, a separate stamp mount with a dedicated embossing member thereon is typically required for forming each image.
An embossing member for removable attachment to a mount has been provided. See in this regard the Glintzes embossing members, made by Inkslingers of San Jose, Calif., which are removably mountable to a mount by a fluid which secures the pieces together by means of surface tension. Such embossing members, however, require a few drops of water or another fluid for attachment and are thereafter slidable over the surface of the mount so as to hinder the retention of the embossing member in a desired location on the mount. Another removable embossing member is provided with a mounting tab which extends perpendicularly from the rear surface of the embossing member and seats within a cooperatively sized recess provided in the stamp mount. The awkward shape of such embossing members hinders their storage and limits the shape of the mount onto which they can be attached.
Some of the stamp assemblies have stamp mounts and embossing members made from an optically transparent material to permit viewing of the surface of the workpiece through the stamp mount.
It is in general an object of the invention to provide anew and improved stamp assembly having an embossing member that is removably secured to the stamp mount of the stamp assembly.
Another object of the invention is to provide a stamp assembly of the above character in which the embossing member can be removably secured to the stamp mount by means of interfacial tack.
Another object of the invention is to provide a stamp assembly of the above character which can be at least partially transparent so as to facilitate placement of the image on the surface of the workpiece.
Another object of the invention is to provide a stamp assembly of the above character in which the stamp mount has a surface for receiving the embossing member which is arcuate in conformation.
Another object of the invention is to provide a stamp assembly of the above character in a which the surface of the stamp mount is concave.
Another object of the invention is to provide a stamp assembly of the above character in which the surface of the stamp mount is convex.
Another object of the invention is to provide a stamp assembly of the above character in which the stamp mount has a bendable wall for receiving the embossing member.
Another object of the invention is to provide a stamp assembly of the above character in which the stamp mount can be a container for storing the removable embossing member.
