UNITED STATES PATENT OEEIcE WILLIAM C. HURD, OF WATERTOWN, CONNECTICUT.

IMPROVEMENT IN DOORS.

Specification forming part of Letters Patent No. 161,965, dated April 13, 1875 reissue No. 6,549, dated J uly 20, 1875; application filed June 21, 1875.

To all whom it may concern Be it known that 1, WILLIAM G. HURD, of Watertown, in the county of Litchfield and State of Connecticut, have invented a certain Improvement in Safety-Doors, of which the following is a specification The object of my invention is to render wooden doors proof against penetration by ordinary wood-angers in the hands of burglars.- Tothis end my improvement consists in introducing a thin sheet of chilled iron or other suitable metal into the body of Wooden doors, covering about the entire area of the same.

In the annexed drawings, Figure 1 is a perspective view of a door embodying my invert sheet A of metal between the halves, as illustrated in the drawings, the metallic sheet extending either to the edges, or to at least within near proximity to the edges.

I disclaim the metal plating of Wooden doors upon the outside, that being very old. My construction differs from that in locating the metallic plate within the body of thedoor,

so as not .to interfere with the exterior ornamentation thereof. I prefer not to let the metallic plate extend quite to the edges, both for concealment and better securement of the plate, and'to prevent its protrusion in case of shrinkage of the wood portion of the door.

What I claim as my invention, and desire to secure by Letters Patent, is-- A wooden door containing, between the exterior surfaoestof the sashing, a sheet of chilled iron or other suitable metal, substantially as and for the'purpose specified.

WILLIAM G. HURD.
