KNOB ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 638,940, dated December 12, 1899.
Application filed October 4, 1899. Serial No. 732,515. (No model.)
Be it known that I, JOSEPH B. SARGENT, of the city and county of New Haven, State of Connecticut, have invented a new and useful Improvement in Knob Attachments, of which the following is a full, clear, and exact description, when taken in connection with the accompanying drawings, which form a part thereof, and in which- Figure I represents a side elevation of a knob attachment embodying my invention; Fig. 2, a longitudinal vertical section of the saine; Fig. 3, an end view of the knob; Fig. 4, an end view of the coupling-sleeve; Figs. 5 and 6, a side and an end view of the independent shank; Figs. 7 and S, a top andan end view of the spindle; Fig. 9, a side elevation of the checking-screw.
In all figures similar letters of reference represent like parts.
This invention relates to door-knobs,'and more particularly to the method of attaching the knob to the spindle, whereby the knob maybe accurately adj usted longitudinally on the spindle to fit snugly against the escutcheon or frame of the door and at the Sametime be prevented from any disadj ustment in the ordinary movements of the knob in operating the lock to which the spindle is connected or in opening and closing the door.
To this end the invention consists in the improvements and novel combinations of parts set forth and claimed hereinafter.
Referring to the drawings, the part designated by the letter A represents the knob of a door, the shank I3 (or portion thereof) of which is formed separate or independent of the knob. Both the knob and shank are provided with angular axial perforations a and b, respectively, corresponding to and adapted to receive the angular spindle C. The knob is further provided on the integrally-formed portion of the shank with an external screwthread a. The shank B has formed at one end any annular flange b and on one or more of the sides of the angular perforation b a longitudinal slot or groove b2, internally threaded. The spindle C has on one or more of its sides a longitudinal slot or groove c, corresponding to the groove b2 in the shank B, also threaded.
being adapted to engage when in proper position with the annular flange b of the shank B and the thread e' to engage the external threading a' of the knob A. i
The parts are assembled by lirst slipping the coupling-sleeve E over the shank B,where upon the shank"B is fitted on the spindle C until its end b3 is in contact with the door or escutcheon, the slot b2 corresponding with the slot c of the spindle. The screw D is thereupon screwed into the slots b2 and c, thereby engaging both the shank and spindle and prea ventingpany longitudinal movement of the shank on the spindle. The shank may be further provided with a shoulder or stop b4 at the end of the slot b2 to limit the movement of the screw D, if desired. The knob A is brought on the spindle and forced as close as desired to the shank B, and if the screw is so long as to extend beyond the end ofthe shank B a slot a2 may be provided in one side of the axial perforation a in the knob to permit the entrance of the end of the screw into' the interior of the knob. Finally, the couplingsleeve E is screwed onto the end of the knob until the ange c engages the flange b of the shank B and holds the parts fast in their proper position.
By this construction the shank B may be adj usted to any desired position on the spindle C, and when the screw D is in place the shank B is necessarily held in its adjusted position on the spindle. The knob A, shank B, and coupling-sleeve E, when in position, entirely inclose the screw D and prevent ac cess thereto, so that accidental movement of the screw is prevented. Y
Having described my invention, the details of which may vary without departing from the spirit thereof, what I claim, and. desire to secure by Letters Patent, is-
1. A knob attachment, consisting of the IOO knob With a portion of the shank formed separate therefrom; of an independent spindle on which said knob and shank are Capable of longitudinal movement; a checking-screw adapted to be screwed into a longitudinallyextending slot or groove in said spindle to engage said shank and prevent the movement of said shank on said spindle; anda coupling device for locking together said shank and knob, substantially as described.
2. A knob attachment, consisting of the knob With a portion of the shank formed separate therefrom, said knob and shank having angular axial perforations; of an independent angular spindle adapted to fit into said axial perforationsaid spindle and shank hav ing longitudinally-extending threaded slots or grooves corresponding to each other g a cheeking-serew adapted to enter said slots and' JOSEPH B. SARGENT.
