UNITED STATES PATENT OFFICE.
GEORGE E. TYSON AND MILLER M. DEEM, OF READlNG, PENNSYLVANIA.
STOVE-DOOR KNOB.
SPECIFICATION forming part of Letters Patent No. 389,177, dated September 4, 1888.
Application filed April 2, 1887. Serial No. 233.386.
T0 aZZ whom it may concern.-
Be it known that We,GEORGE E. Tyson and MILLER M. DEEM, both citizens of the United States, residing at the city of Reading,county of Berks, State of Pennsylvania, have invented new and useful Improvements in Knobs, of which the following is a specification.
This invention belongs to the class of separable knobs, having the parts securelyheld in contact with eachother in a cheap and novel manner.
The object of the invention is to secure a knob, readily cast, that may be assembled and the parts closed upon each other without expensive machine -work, and that will withstand rough usagewithout risk of subsequent separation.
The drawings herewith, forming a part of this specification, show several equivalent modes of carrying out our invention.
Like letters of reference indicate similar parts throughout.
Figure 1 represents a completed knob in full elevation, showing shell A,cap B, and perforations G, with a reverse plan of the seat of the knob, showing lugs A", adapted to enter recesses provided for the same in the plate to which it is to be applied, or in a separate washer, whereby turning of the knob is prevented.
Fig. 2 shows a separable knob, A B, in which the spindle D is driven into the cap-boss B and the collar E, forming an integral portion of said spindle, is by a special set, F, driven down within a recess, A", provided for the same in the seat A of the knob, the position of the knob being reversed, cap B down, shell A set upon the same, and the spindle D introduced from the seat end A and driven down by set F into the eapboss B until the collar E enters the seat-recess A in the shell, when, the drivin g being continued, the collar brings cap-joint B and shell-joint A into bearing with each other, and the knob is complete.
Fig. 3 represents a cap, B, with the spindle D cast in the boss B of the same. The collar E in this case is loose or independent of the spindle, and has its aperture slightly smaller than the diameter of the spindle. In this case the cap B is reversed,with the spindle D projecting from the same through the shell-seat A, the collar E placed upon the slightly (No model.)
smaller screwed portion of the spindle, and, with the hollow special tool F placed over the threaded end of the spindle, the collar E is driven down into its seat A in the shell, scraping off the spindle D as it advances toward the shell-seat A, until it is finally lodged in the recess A with such frictional effect that the separable parts A and B are permanently held in place.
Fig. 4 represents a cap, B, with a threaded boss, B and the spindleD threaded at one end, D, to correspond with the threaded boss B in the cap, the collar E in this case forming an integral part of the spindle D. The collar in this case we preferably make square on plan. The recess A being correspondingly formed to combine the parts, the spindle D is screwed into the boss B until the shell A is brought snug against the cap at B with the square collar in the recess, when,the process of turning or screwing being continued,the knob is con1- pleted by the parts being uniformly combined.
These knobs may be cast of any suitable material. \Ve give preference to cast-iron on account of its cheapness and the readiness with which it may be treated to represent the more expensive metals. The joints A of the shell and B of the cap are plain, and in nearly every case will leave the tumbling-churn in a fit condition for assembling. In place of forming the lugs A on the base of the knob the knob itself may have a hexagonal or square base, G,with a corresponding recess,(}, in the plate; or the lugs H may be cast upon the plate and corresponding apertures H be formed in the base of the knob to prevent turning when applied to the plate. All the spindles are threaded at D for a retaining-nut, by which theknob is removably attached to its door or plate.
The knobs may be perforated, as at O, for the purpose of ventilating the same and preventing their excessive heating when used upon stove-doors.
The forming of a knob in separable pieces and the ventilation of the same being old,what we desire to cover as our invention is merely the general method employed of securely holding such pieces together, forming a knob by means of a spindle which shall enter but not pass through the eap-piece, thus avoiding the marring of the appearance of the knob by its projection; also the means employed for preventing the knob from turning when once sc- 3.
