IMPROVEMENT IN CLOCK-DIALS.

Specilication forming part of Letters Patent No. 213,350, dated March 18, 1879,' application tiled January 30, 1879.

To ali whom t may concern:

Be it known that l, S. EMERSON Boor, ot Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Clock-Dials 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to malte and use it, reference being had to the accompanying drawings, which form part of this specitication.

My invention relates to an improvement in clock-dials, the object being to provide a paper dial with a metallic rim or scalp, secured in such a manner that the outer edges of the paper dial will be held snugly against the inwardly-preiecting iiange ot' the metallic rim or scalp, and thus dispense with a metallic bach for securing and retaining the paper dial in place; and to this end my invention consists, iirst, in the combina-tion, with a paper dial, ot' a metallic rim or scalp secured at its inner edge only to the outer edge ot' the paper dial by prongs or clips connected with the metallic rim second, in the combination, with a paper dial having notches in its outer edge, ot a metallic rim or scalp having clips or prongs formed on its inneriiange and integral therewith. said prongs or clips being engaged with the notches in the paper dial, and serving to secure the latter in place.

ln the accompanying drawings, Figure l is a plan view ot' my improved elocledial. Fig. 2 is a rear view. Fig. 3 is a transverse section; and iig. 1, an enlarged sectional view, showing the attaching-prong and its method otl engagcmen t.

A represents a paper dial, preferably made et heavy paper-stock to prevent its warping when subjected to different temperatures and climates. The outer edge of dial A is provided with any desired number of notches a., the inner walls, of, of notches a being formed on a line with the inner edge of the metallic scalp or rim. B is the scalp or rim, made otl any suitable metal, and constructed with an inwardlyprojecting liange, O, and an outwardly-projecting tiange, D. rlhe outwardly projecting tlange D constitutes a seat for the dial to enable the same to be secured to the clock-ease, whichis effected byinsertingscrews through the ange D and into the front ofthe clock-case. Theinner flange, O, serves as an annular seat for the paper dial, the outer edge of which overlaps the iiange O and seats snugly against the rear suriace thereof.

Upon the inner edge ot' the inner tlan ge, C, are termed any desired number of clips or pron E, which are turned outwardly at right angles to said ange, and the paper dial then applied so that the notches a therein will reg ister with said prongs when the outer edge of the dial is pressed against its seat, and the prongs turned inwardly, as represented in Fig. i3, thus firmly securing the paper dial in place.

As the fastening is eitected at the inner edge ot" the metallic rim, the paper dial is eil t'ectually prevented Jfrom warping so as to produce an open seam or joint between the dial and rim or scalp, which would oiten be the case were the outer edge et' paper dial secured to any other portion of the metallic rim or scalp except its extreme inner edge. y

As the metallic rim or scalp is constructed ot' very light and thin sheet-metal stock, the outer edge thereof is preferably turned under and back upon the tlange to forni a double thickness ot' metal for the secure attachment ot the tastening-screws, and to prevent the bending or tearing ot' the outeriiange whenit is punctured or drilled to form the screw-holes.

A dial constructed in accordance with my invention is ot small initial cost, as it cousists of but two parts-the dial face, ot'paper, and its encircling metallic rim or scalp; and these parts, when secured in the manner shown and described, are firmly attached to eachother, and the dial prevented from be coming separated from the inner tlange ofthe rim. The prongs may be made separate and attached to the rear side of the dial-rim, but are preferably made integral with the rim, to ei'tectually obviate any danger of the accidental separation or displacement of the paper dial when attached to a clock.

l t is evident that slight changes in the conA struction and form ot' the parts may be ref' sorted to Without departing from the spirit of my invention, and hence I do not limit myself to the exact construction shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Let-V ters Patent, is-

1. A clock -dial consisting essentially in the combination, with a metal rim or scalp, of a paper dial, the outer edge of which is secured to the inwardly-projecting ange of the lnetallic rim or scalp by means of prongs or clips connected With the inner edge-of the scalp or rim, substantially as set forth.

2. In a clock-dial, the combination, with a metallic scalp orrim having clips or prongs formed on its inner edge, and integral there-
