W

Resting Wiihin the chamber 10 and adapte i to be moved horizontal therethrough and rotated therein, is a bolimmber including 9. main body portion 91 and integmlly formed extnemities 22. The extremities 22 are eecentnicaily mounted on the bociy poi Mon 21 and are in aiinement one With the other. Centraliy looated wizhin the body portion 21 is a threadod bore 23 adaped to roceive the spinde 24 of a knob whioh serves as means for operating the boit when h6 dom is to ion iocke or uniocked.

From bhe dotail construction of the devioe as -jnst outiined, ifs is obvions that I have provided a look Which inoludos a novei type of boit serving not oniy as a iocking means Tout aise as a means for preventing the ratizling of si door when the boit is adjusted into an opemtive position. It will be apparent that when the door is uniocked, as shown to adva.ntage in Fig. 1, and then iockod, as sot forth in Fig. 4, that one oi the ecoentricaliy mounted extremities, in position for use, Wili npon a rotation of the bolt and horizontal movement of the saine contact with the innerperiphe1y of ho keeper 19 and thus prevent a rattiing of i;he door.

By providing the intermedinte notoh mea-ns are set iorth for reaining the knoia thereinmgainst aooientni dispincemeni of the bo1 when the same in innn opemtfize iceeper being providod of iilusiration is shown a invention herewitb shown and descrbed is to be taken as a preierred size and arrangement et parts,
