IMIJROVEMENT IN ROSE FOR DOOR-ENOES.

TO AEL WHMIT MAY CONGERN: y

Bekit known that I, lWI'LLIAM H ANDREWS, of New Haven, in thecounty ofNew Hat-len, and State of Connectieut,have` invented n. new Improvement in Rose for DoorlKnobsuiid I do hereby declare the: following,

when taken in connection with the accompanying drawings, and' theletters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part ofithie specification, and represent, inw l Figure 1, a transverse central section, and in Figure 2 a front view.

This invention relates to an improvement in the construction of the plate secured to the door, alud upon which the neck of the knob rests, commonly called the rosefy Heretofore these'hav'e been constructed either from castvmetal or sheet brass.A The object of my invention is to produce the rose froultin, whereby the cost is very much reduced, and en articlev nearly as good produced; and the invention consists in the construction of the scat to receive the neck of the knob asone'piece, Vand the rose from tin,or similar sheet ineta'l, which cannot` be struck into shape so as to foi-u1 thevsharp angles necessary for the seat of the neck of `the knob, and perforated at its centre, so that the rosewill pass down over the neck, and the neck extend through the said plate.

To enable others to understand my improvement, I'n'ill fully describe the same asillustratedtin the accompanying drawings. Y l

From tin, or other cheap metal, I strike up the rose A, with a perforation throughthe centre, the diameter equal to the outside of il projecting flange, a, formedupon a. plate, d, as seenin iig. l, thesaid pleite dhaving a hole,f, through its centre sulciently large to permit the spindle to pass therethrough, and so as to leave a.

shoulder, c, upon the inside of the flange a, for. the neck ofthe knobto rest upon, ns seen in therdrawings.

The plate dmay be secured to the door by points formed up'ou its under surface, or by other-means; then over the plate the rose A is set, iitting closely to the flange a, so as to appear in one' and the same piece.

It is impossible to strike the rose whole and icomplete from sheet iron or tin in like manner as is done from vsheet brass, the diiculty being to form the socket to receive the neck of the knob, but by the insertion of the detached neck or ange a' this -diliiculty is overcome, and Va.l rose produced, which, tinned, makes nearly as good an appearance as a plated brass rose, heretofore in Vgeneral use, and Vthe neck or plate d being cast, and the rose struck from sheet metal at a single operation, the cost is very much reduced. i

I do not wish to be understood :is ,broadly claiming` a plate'beneath the rose, upon or against which 'the' neck of the knob rests; but l What I'do claim as new and useful, and desire to secure b'y Letters Patent, is- The combination of th'e plate d, constructcd'with the Bange at, with the plate Artzormed from tin, or similur. hard metal, as described, and when the' flange a extends up throughthe central perforation of the plate'A,

substantially as and 'for the purpose set forth. p
