' nNoB.
Application filed. August 27, 1927. Serial No. 215,808.
This invention relates to a knob assembly, and is'particularly' applicable-to a'knob assembly such as a door-knob for a glass or other easily fractured knob.
Heretofore, glass knobs have been provided at their rear which is knurled or notched. On the shaft of .the knob assembly there is a sleeve having projections which engage in the notches or in the knurled surface of the knob to hold the knob against rotation with respect to the sleeve. The V sleeve and the knob are connected by means of a thin sheet metal ferrule which is spun over a bead on the knob. Such a construction, while being of neat appearance, will not stand up under usage forthe-reason that the thin metal ferrule is easily bent when the knob is pulled.
According to the present invention there is provided an assembly which will form a much more secure connection between the knob and its mounting and wherein the ferrule will serve only to enclose the other parts of the knob and not be subject to mechanical strains as it is inthe present constructions.
My invention may be readily understood by reference to the accompanying drawings, in which Figure 1 is a vertical longitudinal section through a portion of aknob assembly enrbodying my invention;
Figure 2 is a side elevation of the knob;
Figure 3 is a view of the rear face of the knob; V
Figure 4: is a perspective view of the sleeve on which the knob iscarried; and
Figure 5. is a detail section on a scale larger than Figure 1 and at rightrangles thereto. Y i
In the drawings, ing an extension 3 at the back thereof with a bead f thereon. Formed in the end face 5 of the knob is a dovetail groove 6. As shown in Figure 3 the dovetail groove 6 is slightly wider at one end than at the other to facilitate the formation of the knob in a press. Fitted into the dovetail slot 6 is the crosshead 7 at the end of a sleeve 8. The cross head 7 has tapered sides to. cooperate with the dovetail groove 6 in the glass knob. The inside of the sleeve 8 is threaded, and screwed into the sleeve in the knob spindle 9. The knob spindle 9 passes all the way through the sleeve, as clearly shownin Fig ure 5, and its end bears against the bottom of the groove 6. Bv turning the shaft 9 faces with an extenslon sheet metal.
wise ornamented. The practice 2 designates a knob havrelatively to the sleeveS, the knob may pushed away from the cross bar 7 to cause the sides of the cross bar to frictionally clamp the sides of the dovetail groovefi and ghereby firmly hold the knob on the cross Mounted onthe sleeve 8 is a ferrule 10 of The outer portion 11 of this ferrule is spun over the bead 1 to enclose the connection between the sleeve and the knob. A set screw 12 passes through the ferrule and through the sleeve and bears against the shaft 9 for holding the parts in fixed relation. V
The end face of the knob, including the bottom of the groove Gmay be suitably ornamented so.as to'show through the knob whenit is assembled. For the purpose of increasing .the ornamental effect, the en face of the knob may be silvered or otherof silvering the end face of the knob is now resorted to. If'desired, the face of the cross bar 7 may be suitably ornamented to show through the knob.
An assembly embodying the present construction can be quickly put together. The strain onthe knob is transmitted to the cross bar 7 without being transmitted through the ferrule 10. Heret-ofore the ferrule has formed the only positive connection for holding the knob and the sleeve against strains in a direction longitudinally of the spindle 9 and the turned-over portion 11 0f cut construction the longitudinal strains are absorbed in the cross bar 7 and the undercut or dovetail groove 6 in the knob and the furrule forms only an enclosing shield.
While I have specifically shown and described a specific embodiment of my invention, it will be understood that various changes and modifications may be made in the construction thereof without departing from my invention or the scope of the appended claims.
I claim: 7 V
1. A knob assembly comprising a knob having an undercut slot in the rear face thereof, a sleeve having a cross bar engaging in said slot, and a shaft threaded through the sleeve and adapted to bear against the end face of the knob.
2. A knob assembly comprising a knob having an undercut slot in the rear face i 1 1 fining the knob in said slot, a shaft g g} sleeve, and a ferrule enclosing the sleeve and embracing a portion 6 movement on the cro 3. A knob ,assemb threaded through the i of the knob and conagainst transverse sliding ss bar/ ly comprising a knob having a transversely extending dovetail groove 1n the rear face thereofia sleeve'having a cross bar thereon, sald cross bar being of theknob anda shaft threaded 4. A knob asseinb 7 l0 shaped to cooperate with the dovetail groove and being entered in said through the sleeve. ly comprising a knob cross bar thereo groove,
closing the sleeve and embracing the bead, and a shaft threaded through the sleeve with its end bearing against the end of the knob.
In testimony vvhereof I have hereunto set my hand. I FRANK J. PETERSON.
