DOOR -KNOB ATTACHMENT AND LOCK.

SPECIFICATION forming part of Letters Patent No. 613,169, dated October 25, 1898.

Application filed. October 29, 1897. Serial No. 656,847. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN W. T. MORRIS, a citizen of the United States, residing at Summerland, in the county of Santa Barbara and State of California, have invented certain new and useful Improvements in a Combined Door-Knob Attachment and Look, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, which form a part of this specification.

My invention relates to certain improvements in securing door-knobs to the knobshaft, the same being adjustable to take up lost motion and prevent wear and noise by dispensing with the rattling incidental to devices of this nature, and to form an efficient look when the same is desired by preventing the knob-shaft from turning in the door; and my invention consists in certain features of novelty hereinafter described and claimed.

Figure I represents an edge elevation of a door, the same being broken and showing my improved door-knob attachment and lock. Fig. II is a vertical section of a portion of the door and a longitudinal section of the knobshaft, showing means for securing the knobs to the shaft. Fig. III is a transverse section taken on line III III, Fig. I. Fig. IV is a side elevation of the inner'knob. Fig. V is a transverse section taken on line V V, Fig. IV. Fig. VI is a broken View of the edge of a door,showing myimproved means for locking the knob-shaft. Fig. VII is a section taken through the center of the outer knob and its sleeve. Fig. VIII is a side elevation of the inner locking-pin. Fig. IX is a front elevation of the inner locking-pin. Fig. X is a side elevation of the outer retaining-pin. Fig. X1 is a plan view of the knob-shaft. Fig. XII is an end View of the knob-shaft. Fig. XIII is a broken view of the inner escutcheon-plate with collar thereon shown isometrically. Fig. XIV is an isometrical view of the inner escutcheon-plate, showing the under side of the collar connected therewith. Fig. XV is an isometrical view of my improved locking-ring. Fig. XVI is a detail view showing operation of locking-ring.

Referring to the drawings, 1 represents the door, 2 the outer knob, and 3 the inner knob.

4 represents my improved knob-shaft having a central portion 5, which is non-threaded and having screw-threaded ends 6.

7 represents longitudinal grooves in the knob-shaft, which extend from the ends of the same to the squared central portion 5. The knobs 2 3 are provided with internal threaded sleeves 8 9, by which they may be screwed onto the knob-shaft 4 and adjusted according to the thickness of the door 1. The sleeve 8 of the outer knob 2 is provided with a hole 10, in which may be inserted a pin 11 for securing the outer knob to the knob-shaft, or, in other words, preventing its turning upon the knob-shaft 4E. The pin 11 is provided on its inner face, near its upper end, with a groove 12, surmounted by ahead 13, the groove 12 in the retaining-pin 11 fitting over the collar 14. on theouterescutcheon 15, and as the lower end of said pin 11 extends into the groove 7 of the knob-shaft 4 the outer knob is prevented from rotating on the knob-shaft, and as the collar 14 rests in the groove 12 the pin 11 will be prevented from withdrawal until the knob-shaft has been shifted outwardly.

16 represents a small notch 011 the outer face of the pin 11, in which a tool may be inserted in order to Withdraw said pin 11 when it is desired to detach the outer knob from the knob-shaft. The sleeve 9 of the inner knob 3 is provided with a series" of holes 17, in order to finely adjust the inner knob to the knob-shaft.

18 represents a locking-pin having an inner shoulder 19 and a notch 20, said notch serving the same purpose for withdrawing the pin as the notch 16 on the pin 11. The pin 18 is inserted in one of the holes 17 in the sleeve 9, its lower end extending into the groove 7 in the knob-shaft, the inner knob being capable of fine adjustment by said pin 18 being inserted in either one of the holes 17 in the sleeve 9, thus taking up any lost motion between the knobs and knob-shaft. When said pin 18 is in position, it will prevent the knob 13 from turning without turning with it the knob-shaft 4.

21 represents the inner escutcheon, having an outwardly-extending collar 22 thereon, said collar being provided with shoulders 23 and a notch 24 cut in the outer face of the collar. The purpose of the notch 24 in the ICO collar 22 is to permit the insertion of the locking-pin 18 or the withdrawal of the same, the shoulder 19 of the locking-pin 18, passing beneath the outeredge of the collar 22 as the knob is partially rotated in opening or shutting the door, the collar thus holding said locking-pin 18 from withdrawal until it is adjusted to coincide with the notch 24, at which time it may be withdrawn, if desired.

25 represents a pin or stud on the under side of the collar 22.

26 represents my improved locking-ring adapted to fit over the collar 22.

27 represents a slot in the locking-ring which passes over the pin 25 on the collar in placing the locking-ring in position.

28 represents an ofiset in the slot 27, into which the pin 25 passes as the locking-ring is partially rotated, said offset and pin serving to hold the locking-ring in its extreme inward position and at which time the locking-ring is not performing its office of locking the knob-shaft.

29 represents a notch on the outer face of the locking-ring which corresponds with the notch 24 in the collar 22 and is for the same purpose of permitting the pin 18 to be inserted in position.

30 represents a recess on the outer face of the locking-ring 26, said recess being somewhat wider at its rear end than it is at its forward end. The purpose of the recess 30 is to permit the locking-ring to be moved outwardly and engaging the upper end of the locking-pin 18 for the purpose of serving as a lock and preventing the knobs and shaft from rotating. As the locking-ring is moved outwardly to engage the locking-pin in order to lock the door, the pin 25 on the collar 22 still remaining within the inner slot 27 prevents the locking-ring from rotating, and thus firmly locks the door. The recess 30 is made wider at its inner end, so that the same will be readily retained upon the pin 18 until such time as it is desired to shift the locking-ring backward and unlock the door, at which time a slight turning of the lockingring causes the pin 25 to again enter the offset 28 and hold the locking-ring in its inner position.

\Vhen the locking-ring has been pressed backward to unlock the door, the knob-shaft may be turned to a limited extent to force the latch backward when it is desired to open the door. The rotation of the knob-shaft is limited by the pin 18 coming in contact with the shoulders 23 of the collar 22.

I claim as my invention- 1. The combination of a grooved knobshaft, an escutcheon having a collar, a knob having a sleeve with a hole therein, a locking-pin having a shoulder and a locking-ring on the collar adapted to engage the lockingpin and prevent the rotation of the knobshaft, substantially as set forth.

2. The combination of a grooved knobshaft, an escutcheon havinga collar, a knob having a sleeve with one or more holes therein, a locking-pin having a shoulder, a movable locking-ring and recesses in the lockingring and collar for the insertion of the locking-pin, substantially as set forth.

3. The combination of a grooved knobshaft, a knob having a sleeve, a pin adapted to extend through the sleeve and into the grooved knob-shaft, a locking-ring having a recess, said locking-ring being movable so that the locking-pin will extend into said recess when the ring has been shifted outwardly, a slot on the rear side of the lockingring, a pin on the collar of the escutcheon adapted to enter said slot and an offset in said slot into which the ring of the collar may pass in order to hold the locking-ring at its extreme inward position, substantially as set forth.

4. The combination of a grooved knobshaft, knobs having sleeves thereon, holes in said sleeves, locking-pins adapted to extend through said sleeves, shoulders on said locking-pins and notches on the locking-pins for the insertion of a tool in removing the same, substantially as set forth.

The foregoing specification signed at Summerland, California, this 8th day of October,

JOHN W. T. MORRIS. In presence of BYRON PRESTON, BISHOP A. BEALS.
