IMPROVEMENT IN PICTURE-NAILS.
Specication forming part of Letters Patent No. 55,917, dated June 26, 1866.
To all whom it may concern:
Be it known that I, FREDERICK J. SEY- MOUR, or" Volcottville, in the county oi' Litcheld and State of Connecticut, have invented, made, and applied to use a certain new and useful Improvement in Picture-Nails; and I do hereby declare the following to be a full, clear, and exact description ot' the said invention, reference being had to the annexed drawings, making part of this specification, where- 1n- Figure l is a longitudinal section ot my improved picture nail. Fig. 2is asection ofthe metallic body of the nail-head, and Fig'. 3 is an elevation of the same.
Similar letters denote the same parts in the figures.
Picture-nails have heretofore been extensively manufactured with a removable head, the body of the nail that is driven into the wall having a screw end, upon which the o1'- namental head is screwed after the nail has been driven. These. ornamental heads have been formed with a separate nut attached within the hollow head, and sometimes soft metal has been cast wit-hin the body of the head around the screwed end of the nail. These lnodes of manufacture are expensive and consume considerable metal in the nuts, and the nut is liable to get loose.
The nature of my said invention consists in a picturenail formed with a metal body for the ornamental end or head, in which a projection inward is formed receiving the screwthread to take the nail. Thus the screw-thread is formed out of the metal of the body that ordinarily would be removed in perforating the head for the nail, thereby effecting a saving in the cost and forming a nut that is part of the body and not liable to become loose, as here tofore.
In the drawings, ais the nail, with the screwed end as usual. the ornamental nail-head, to which the porcelain disk or button 0 is to be secured by the ornamental ring d, as usual. In the center of the body or back I) is an opening, formed by perforating and stretching the metall inward in the'form of a short cylinder or teat, i, and the inner surface is provided with a screwthread to fit the end of the nail a. The metal composing the body b should be sufficiently thick to allow of its being stretched inward to form this cylinder i nearly as long as the diameter of the hole through said cylinder.
This improved picture-nail is a cheaper and better article than those heretofore made, as mentioned above, and is a new and useful article of manufacture.
WhatI claim, and desire to secure by Letters Fatent, is
An ornamental picture-nail head made with a screw for the nail, in the manner specitied.
In witness whereof I have hereunto set my signature this 26th day of February, A. D.
