IMPROVEMENT IN BUSH-NUTS FOR DOOR-KNOB ROSES.

Specification forming part of Letters Patent No. 130,131, dated August 6, 1872; antedated J u1y 30, 1872.

I, GoRNELIUs HOOD, of Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Method of Fastening Door-Knob Roses to the Door, of which the following is a specification, reference drawing, in which- Figure 1 is a flatwise view of a door with a rose fastened thereto by my method, the knob and spindle removed. Fig. 2 is a detached view of the exterior of one of the nuts used, which I denominate a bush-nut. Fig. 3 is a detached view of the other nut used, which I term the auxiliary nut. Fig. 4 is a central vertical section of the parts shown in Fig. 1, through the dotted line a a. This invention consists in fastening the rose to the door" by two nuts, the bush-nut and the auxiliary nut, whose constructionand use arefully described hereinafter.

The letter It indicates the side of a door, on which is the common rose 0, struck up out of sheet metal, and fastened to the door by means of the bush-nut d and the auxiliary nut e. A flange, d, on the upper and outer end of the bush-nut, takes hold of a turned-in flange which is at the bottom of the depression, which surrounds the hole in the center of the rose 5 the bush-nut is driven by means of a common screw-driver, the point of which fits into the nicks d 0?, made on its upper face. This bush-nut is driven into the auxiliary nut e, which has been driven into the door previously, being interiorly and exteriorly threaded for that purpose.

By means of the use of these two nuts the rose is much more firmly fastened to the door than in the ordinary way, and they form a very firm arid strong bearing for the spindle.

. This combination of nuts is peculiarly valuable in repairing doors which have been in use for some time, and where a rose fastened in the ordinary way has become loose, and consequently the spindle has worn a considerable hole in the door. Here the auxiliary nut fills up the worn space, and with the bush-nut gives the spindle a firm bearing Once more.

I claim as my invention In combination with the bush-nut, the auxiliary nut e, interiorly and exteriorly threaded, substantially as described, and for the purpose set forth.
