Builder's hardware; a manual for architects, builders and house furnishers . Fig. 372. Morris Patent Door-knob. Ireland Mfg. Co. from the door. Figure 371 is a device practically the same asthat shown by Figure 368. Figure 372 is still another varietyof the same general style of attachment, using a steel binding-screw to hold the knob-shank in position. The Yale & Towne Manufacturing Companv has recentlyput on the market a form of screwless knob-shank shown by DOOR-KNOBS. 248. Fig. 373. Screwless Towne Mfg. Co. Figure 373. In this case the spindle is turned round at each end and threaded. The knob is provided with a swivel-nut, D, which fits the thread of the spindle. In applying, the nut is turned up until it bears slightly against the face of the rose, and is then left in that position, a washer being interposed between the rose and the nut. The nut takes the place of the ordinary shank, and as this portion of the knob is seldom touched, there is little liability of the nut working loose, especially as it can be turned up pretty tight, and is made so as not to work too easily. A very simple and effective form of screwless knob-fasten-ing has been recently brought out by the Plopkins & DickinsonManufacturing Company. In this device, the spindle, which iscut with a screw-thread, is rigidly attached to the shank and theknob on one side. The opposite shank has a swivel connectionwith the knob, and is threaded inside to screw over the spin
