Builder's hardware; a manual for architects, builders and house furnishers . anufacturer has it on his catalogue-list. Anything else is really an exception, and we know ofonly one instance in which a manufacturer has undertaken topush exclusively a single form of knob attachment differingfrom the common style. It must not be thought, however, thatno clever or good devices have been thought out. It is hard tosimplify simplicity, and the screw connection, all things con-sidered, gives eminent satisfaction. The first variation from the old style has been to enlarge therose, extending it out over the shank so as to partially or completely cover the screw-hole, a slot being left at each sidethrough which the screw can be applied, the rose subsequently Knob and Spin-being turned and secured against the door so as to completely partly the screw. Figure 366 shows such a form. This de-vice renders it absolutely impossible for the screw to become 240 Chapter XII. Spindle-Screws & Er-win Mfg. Co. Threaded Spin-dle. Stoddard LockMfg. Fig. 367.

Still,this is an improvement, and when well applied is very satisfac-tory. The next step has been to cover the screw entirely.

The screws which hold the rose to the doorpass through both the outer shell and the inn
