ADOLPH MUEHLMATT, OF NEWPORT, KENTUCKY.

HOLDER FOR nnenavmo-nmcxs.

To all whom it may concern:

Be it known that I, AnoLri-r MonnLMA'rr, a citizen of the United States, and a resident of the city. of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Holders for Engraying-Blocks, of winch the following is a full, clear, and ex-' act description, reference being had to the accompanying drawings, forming part of this specification.

The use for an engraving block in the art of engraving, of a heavy, metallic truncated sphere, on the cut-otf portion of which a vise for holding the material is placed, is universal in the art. It is heavy and roundedatthe bottom to give stability and to permit. an easy change of position for the convenience of the engraver. It is held tight. in place by using as a holder a pad tilled usually with sand and covered with leather, in the middle of which a hollow may be pounded to serve as aseat. These holders, often of home manufacture, are necessarily subject to a great deal of wear and tear, and once worn out. have to be replaced or re-covered, with the inevitable loss of efficiency in the latter case. The or-,

dinary pads are stifi' when first made and become soft. depressed and out of shape with use, so that..t.he blocks are not held at a uniform height.

it is the object of this invention to provide that certain construction, as 'will be more specifically pointed out and described, whereby the necessary support. can be provided in an efficient. and inexpensive way.

In the drawings, Figure 1 is a view of the improved holder. in vertical section, with the en zravers block in place. Fig. 2 is a perspective view of tlie'liolde1','pa1'tly broken away'to show the construction of the ring.

The engraving block shown consists" in the metallic spherical portion 1, with the of the vise. surmounted by the attaching jaws 3, 3. The jaws 2, 2, carrying the attaching jaws, slide back and forth in the upper portion 4 of the spherical body,

which is shown as a separate part in the block illustrated, and are operated by the Specification of Letters Patent. Application filed December 16, 1912. Serial No. 737,032.

Patented Apr. 1,1913.

right and left threaded screw 5, 5. A block of this kind, which is merely used for purposes of illustration, usually weighs about twenty pounds.

As a seat for the block, an annular shaped support 6, preferably made of wood or other suitable material, is provided. 'Ihis.supporthas an outside, upwardly extending flange or wall 7, which with the base portion 8 forms a seat for the ring 9. .The base portion '8 is preferably only wide. enough to fully act as such seat and its inner edge forms a circular opening 10, over which the, base of'the block is to be suspended.

The ring 9-is of such size as will fit snugly into the seat so -formed for it. The necessary features of its construction are that it should he cylindrical in shape and made of somewhat resilient material, with a surface soft enough to resist the movement on it of the block. My preferred construe tion is as follows: Th inside portion or 'core 11 of the ring 9 is made of rubber of correct resiliency, which is covered withthc leather cover 12, sti ched at each side as shown at 13, 13.

My improved holder gives a correct full annular contact and bearing surface for the block. as against the uuevensupport of the ordinary pad.

.The resiliency of the support, is constant and maintains the block always at the same height. The wooden dish-like. support prevents wear on and sanitarysupport which ,will not take-1y. grease and dirt, as in the'case of the ordithe pad and presents a clean nary pad, and which can always be kept in good condition ree from dirt r l-laving thus described. my invention, what T claim as new and desire to secure by Letters Patent, is:-

A holder for engraving blotzlts comprising a separable, resilient ring and a hard dish-like support for the ring cut away atthe center to permit the ring to suspend the block'.
