Application filed October 20, 1908. Serial No. 458,653.
To all whom 'it may concern:
Be it known that I, GILBERT W. Goonnmcn, a citizen of the United States of America, and residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and Improved Electric-Lamp-Socket Cap, of which" the following is a specification.
My invention has particular reference to the sockets for incandescentelectrlc lamps of the character forming the subject of my Letters Patent No. '87 9,819, dated February 19,1908, and'No. 872,283, dated November 26, 1 907. In the preferred forms of those sockets the flanges of the caps are each provided with a large number of symmetrically arranged openings tofcooperate with engaging means on the shell, and as shown in my Patent 87 2,283, the flan e of the cap is preferably also corrugated ongitudinally of its axis 111 proportion to the number of openin therein.
he main object of my resent invention is to so construct a cap of this character that it will be stronger and more rigid than the old style caps, and easier to finish and polish! in manufacturea dyet possess all the advantages growing out-of the use ofmy said atented inventions. This object I attain as ereinafter described.
In the accompanying drawing Figure 1 is a perspective view showing two parts of my cap before they are put together; Fig. 2 is a view of the same two parts before, being put together, the cap being in outside view and the ring in section; 'Flg. 3 is a sectional view of the finished cap."
. B is the cap with any usual, or suitable nipple b and having a flange D with a large number of symmetrically arranged holes (5 throu h its walls. In the particular construction illustrated the fla D is also corrugated parallel with the axis of the cap,
the number of corrugations 6 being proportional to the number of openings d. I provide-a smooth ring F with a narrow rim or flange f at its u per ed e to fit closely over the perforated flhnge 0% the cap, the rim 7 fitting over theannular shoulder above the corrugations where the flange joins the dome of the cap. This rin F is made just sufliciently ion or than t e flange D to permit its lower c e to be then turned at f under the rim of t e cap flange D'and be thereby firmly secured in place, so that the smooth ringnot only completely incloses the corrugatlons and openings in the flange but also bears against and supports the corrugations, Thus a cap is produced which is exceedingly strong and rigid in its flange and at the/ E same time a smooth outer surface is presented which .ismueh easier to finish and polish than the corrugated or even perforated flange. At the same time, I am enabled to retain the advantages of the constructions of my former patents.v I
I claim as my invention 1. An electric lamp socket cap, having a flange with numerous perforations and cora rim at one edge fitting over the shoulder above the corrugations and its other edge turned under the rim of the cap flange.
'. In testimony whereof have signed my name to this specification, in the presence of two subseribln witnesses.
