DOOR KNOB AS EMBLY Filed Nov. 8. 1927 W ZZ067%77 Egan)" wmw Patented Apr. 7, 1931 -2 UNITED STATES PATENT oFF ICE.
ALFRED ROGERS, OF MILTON, MASSACHUSETTS DOOR-KNOB ASSEMBLY Application filed November 8, 1927. Serial No. 231,837.
This invention relates to a door knob as sembly, which is so constructed as to conceal and protect the securing elements by which the various parts are held in place and to present a sanitary surface which can easily be kept clean. The resulting structure presents an improved appearance and at the same time, by covering up the fastening elements which hold the parts of the mechanism in place, affords a superior construction which is easily cleaned, and when used out of doors shields the parts from effects of the weather. By making the exposed members of the assembly of non-corrodible material such for l exampleas porcelain, celluloid, or glass, an-
easily cleaned surface is presented, which is particularly desirable for hospitals as it can be made in light colors to exhibit conspicuously any dust or dirt which may be thereon.
For a more complete understanding of the invention, reference is had to the following description and to the drawing, of wh1ch, Figure 1 is a side elevation of an improved door knob assembly embodying the invention.
Figure 2 is an end elevation of the same. Figure 3 is a side elevation of the same, a portion being shown in section.
Figure 4 is a perspective of the same, some of the parts being separated to indicate their individual shapes.
Figure 5 is an end elevation of one of the members of the apparatus, a portion being broken away.
Figure 6 is a section on line 66 of Figure 5.
Referring to the drawing in detail, 10 represents conventionally a door knob shaft which is customarily of substantially square cross section. This shaft extends through the door and when in use is so related to the latch mechanism in the door that when it is turned it retracts the latch. The door knobs of a door are customarily attached to the opposite ends of the shaft, and in order to pre- 5 vent excessive play or wabbling on the part of the knobs a bearing member or plate is customarily secured to each side of the door having an aperture through which the shaft extends, and in which it is held in a position substantially perpendicular to the plane of v shaf -1O and to permit it to turn easily therein. The plate 11 may be provided with-perforations-13 through which screws 14 may be driven to secure thefplate to the side-of the door In order to conceal and protect this b plate, which is preferably of metal, 'I may provide a shield 15 of suitable non-corrodible material such as porcelain or the like. As
shown in Figures 5 and 6, this shield has a body portion 16 and a forwardly projecting reduced portion l7.v A central bore 18 extends therethrough and a shallow recess 19 is formed in the rearward face of the body portion. The bore 18 is preferably of a size,
4 to receive the neck 12 of the base plate 11, the
recess 19 being preferably shaped to receive the plate 11'. In the side walls of the bore 18 are formed one or more bayonet slots 20.
These slots are adapted to receive suitable lugs 21 formed on a nut 22, which is threaded to screw on to the neck 12 of the baseplate. The reduced portionl? ofthe'shield 15 is also perforated as at 23 fora purpose to be described. The door knob hasa body, portion 24 to be graspedwhich may be of conventional shape or of any desired decorative shapes and which is preferably of the same .material as the shield 15. From this body portion a suitable flange or skirt 25 extendsi rearwardly,'forming areceses 26 adapted to receive the end of the reduced portion 17 of the shield. A rearwardly projecting core "member 27 is secured to or integrally formed with the body portion of the knob, this core V member 27 being adapted-to enter the bore 18 of the shield. The core member 27is also PI'OYlClBdVVItllZI. longitudinal bore of square cross section to receive in fitted engagement an end portion of the square shaft 10. Their.
shaft 10 may be as usual provided with a plurality of threaded perforations 28 which may be used selectively according to the thickness of the door and which are adapted to receive a screw 29 which is passed through an aperture in the side wall of the core member 27. The screw 29 thus secures the knob to the shaft 10. Since a considerable portion of the core member 27 projects into the bore 18 when in position the perforation 23 in the reduced portion of the shield is provided to permit the insertion of the screw 29 through the core member and into one of the holes 28. In assembling the mechanism on thedoor the base plate 11 is screwed or otherwise secured to the door in such a way as to be concentric with the shaft 10. The nut 22 is then screwed on to the neck 12 and the shield 15 is then placed over the base plate and nut, the lugs 21 being engaged in the bayonet slots 20 to secure the shield firmly in place against the side of the door. The shield is preferably arranged so" that the perforation 23 extends downwardly, thus effectively concealing the perforation and preventing the access of rain water or washing fluid thereinto. The knob is then placed in position, the core member being thrust into the bore 18 in such a way that the perforation therein will register with the perforation 23. A screw 29 is then inserted through the perforation 23 and driven home. The mechanism as thus assembled is illustrated clearly in Figure 3. It is obvious that there are no screw heads ,or openings visible to an observer except the aperture 23 which can be seen only by looking at the mechanism from below. By making the shield and knob of porcelain or some other non-corroding material it is obvious that the metal parts will be completely protected from dust, dirt, rain, or deteriorating eifects of the weather.
Having thus described certain embodiments of this invention it should be evident to those skilled in the art that various changes and modifications may be made therein with out departing from its spirit or scope as defined by the appended claim.
I claim A door knob assembly comprising a base plate having a threaded neck projecting therefrom, a nut threaded on said neck and hav ng an outwardly extending lug, a shield overlying said plate and neck, said shield having an interior bayonet slot to receive said lug, a shaft extending through said neck and shield, a knob having a rearwardly projectlng core member fitting over the end portion of said shaft and extending into said shield, and means for securing said core member to said shaft.
In testimony whereof I have affixed my ignatu ALFRED ROGERS.
