Description
Jan. 18, 1938. H. D. SHAW 2,105,617
DOORKNOB Original Filed Nov. 11, 1935 Patented Jan. 18, 1938 UNlTED STATES PATENT OFFICE DOORKNOB Harold D. Shaw, Fitchburg, Mass, assignor to Independent Lock Company, Fitchburg, Mass., a corporation of Massachusetts 2 Claims.
This application is a division of my prior application on a Doorknob filed November 11, 1935, Serial No. 49,129.
The principal objects of this invention are to 5 provide a construction in which a fine adjustment can be made between the thimble of the knob and the spindle so that wear can be taken up to avoid the rattling of the knob and at the same time of such an extent that it can be used 10 for applying the knob to doors of very different thicknesses; to provide means for holding the knob with respect to the spindle under any condition of adjustment without the use of the usual radial screw; to provide positive means for holding the adjustment, and to provide a simple form of cap for the knob which can be removed easily in case of necessity.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying 20 drawing, in which Fig. l is a sectional View of a knob constructed in accordance with this invention;
Fig. 2 is a side view with the parts separated;
Fig. 3 is a view of the main part of the knob looking in the direction of the arrow 3 in Fig. 2;
Fig, 4 is a view looking in the direction of the arrow 4 in Fig. 2; and
Fig. 5 is an end view of the thimble.
In the form shown in all the figures the usual spindle i is employed. Upon this spindle screws the shank l l and this shank is adjusted back and forth on the screw-threads for adjusting it to different thicknesses of doors and taking up any slack due to inaccurate setting or to wear. The
" shank is provided at its outer end with a noncircular projection l2, in this case shown as hexagonal, this part projecting from a circular fiat surface l3 near the end of the shank.
The knob M which may be made of glass, metal or other solid material, is provided with a circular recess I for receiving the surface l3 of the shank and with a perforation iii of the same shape as the projection l2 to receive that projection and provide a positive connection between the two so that the shank and knob will turn together. On the inside the knob is provided with a flat surface I! opposite the annular re- 5 cess l5.
The knob M has a central perforation 38 and the flat surface l7. At the other end it has a simple shouldered circular recess 40.
A cap 4| simply has an externally threaded central projection 42 screwing into a collar 43. The threaded spindle l0 screws into the other end of the collar. A washer 44 surrounds the spindle against the surface H. A spring 45 bears against the washer 44 and cap 4| to apply pressure to the cap. The collar 43 being threaded on the spindle l0 and on the cap 4| and the cap being held by the spring 45, the turning of the annulus M will be transmitted to the spindle l0 through the cap 4| and collar 43. This constitutes a simple arrangement. 1 It is less expensive to make and maintain than the form shown in the first sheet of my above identified application.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
l. The combination with a door knob and means for adjustably securing it to a threaded spindle, said knob having an open end, of a cap located in said open end, a member in threaded connection with the cap and with the spindle to hold the cap against displacement, and yielding means for exerting an outward pressure on the cap.
2. The combination with a door knob and means adjustably securing it to a threaded spindle, said knob having an open end, of a cap located in said open end, a collar connected with the cap by screw threads, and a spindle con- 0 nected with the collar by screw threads.
HAROLD D. SHAW.
