To ALL WHOM 1Tv MAY coNcERN:

Be it known that I, WILLIAM B. MASON, of Boston, in the county of Suolk, and State' of Massachusetts, have invented a new and useful Improvement in Marking-Tools; and I do hereby declare that the -following is a full, clear, and exact description of the construction and operation of the same-referencebeing had to theA accompanying drawing, forming a part of this specification-sufficient to'enable others skilled in the art to make and use the same without other invention or experiment., y

The present stencil-plate for marking packages, is a contrivance lof a rude andI imperfect character, only adapted for use by persons not facile at handling the marking-brush`securing accuracy at the expense of time,4

comparatively cumbrous Whenrrplore than one personhas to be addressed, and absolutely useless when it is desired tomark articles of irregular surface or conformation. `My invention obviates these diiculties, by employing movable type, so that the address may be readily changed; by constructing these type with elastic faces, to insure an impression from their ywhole surface by securing them so as to 'allow them a rocking motion; and by backing them against an elastic cushion, to obviate'the ill e'ects of irregularity of surface or`conformation which they are to stamp. In

Figure lis given a section of the type, perpendicular to the line of reading. In this, A is the elastic face, of rubber or other suitable material; B is the body of the type, and c c are the flanges, to confine it within the slotted face-plate. l

' Figure 2 is a longitudinal section through a marking-tool, in which A and B represent, as before,'the elastic face and body of the type; d is the face-plate, slotted to allow the type to ne inserted; e is anelastic backing, consisting, in this case, of a rubber ball toAeach type. It might7 however, consist of a block of elastic material, of any shape, or of a spring. Preferably there should be an independent backing for each type, but measurably good results may lbe obtained by a plating or netw`ork of elastic material, particularly if it be provided with knobs or projections below the individual types. '.On inking this type and pressing it, backed as described, upon an irregular surface, the elastic face conforms to the superficial irregularities, while the elastic backing, allowing a rocking motion of the type and a variable pressure, thus causes it to coincide with the variations of general form. This is of great importance when bags or irregular-shaped packages are,to be marked.

What I claim as my invention, and desire to secure by Letters Patent, is-

I claim making the face of the type elastic, to yield to the small inequalities of the surface printed in combination with a small elastic base, (less in area than the face of the typc,') to yield to the large inequalities of the surface printed.

And in combination with the elastic face and small elastic base, I claim so arranging or holding the solid body of the type in the case, that it can rock when required to adapt the surface of the type to the irregularities of the surface printed.

WILLIAM B. MASON.
