Description

.thinned 51ans @anni @time JAMES M. ADOLPHIIS, OE PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 111,297,.dated January 31, 1871 .antedated January 21, 1871.
IMPRCVEMENT IN FASTENINGS FOR DOORNKNOB ROSES.
The Schedule referred to in these Letters Patent and making part of the same.
To all Iwho-ml 'it may concern:
l'into which takes the loose end of' a spring attached to the under plate.
When the shank is turned in the proper direction, its flange is pressed-lirmly ou the head or top of the rose, thereby holding it Iirmly'and securely inplace.
On reference to the accompanying drawing making part of this specification- Figurel shows the under plate and holding-spring;
Figure 2 is a sectional-.view of the rose and under plate, showing the shank and its groove; and
Figure 3 is an extemal View of the shank.
Similar letters refer to similar' parts in these-verni views. i
A, figs. 2 and 3, is the shank usually employed to secure the rose or porcelain B of a lock to the opposite side of a door. It` has a groove, a., formed in its surface. Oonunencing at its lower or bottom end, it
extends longitudinally a suitable distance, and then. inclines, forming an obtuse angle,
C is the bottom plate, which is screwed to the door D oppositely to the lock. neck, E.
F is a spring or catch, fixed to the bottom piece G.
It has a hollow projecting Its loose end l) takes through anopening formed in the neck E.
To secure the rose'or'porcelain B in placethe bottoin piece G is first screwed to the door D, and the porcelain set'over it. The shank A is then passed into the hollou7 of the neck E, the end of the spring ll taking into the longitudinal part of the groove a, Whenit arrives at-the bend or angle, the shank is turned. The ascendingpart of the groove, being au inclined plane, bears greater on the end of the spring thelmore the shank is rotated, and brings the ange c firmly on the top of the rose B,'therehy keeping it lirmly and securely in place. i
-As now constructed, the socket A has a screw formed on its smaller diameter d, which takes into-a 'corresponding screw in the under plate. It is objected to for the reason that the socket becomes u nscrewed hy the door-knob beingvconstantly turnedin opening and shutting the door. The threads of the screws become stripped and broken, whereby the rose loosens and cuts a circular' in the door by repeated turning.
That I cla'irn as my invention, and desire to secure by Letters Patent, is-
The shank A, having a groove, a, in combination with the spring or latch F, substantially as shown and described.
In testimony whereof I hereunto sign my name to this specification in the presence of two subscribing witnesses.
