To all whom it may concern:
Be it known that 1, WILLIAM H. HOPE, a citizen of the United States, residing at Providence, in the State .Of Rhode Island, have invented a new and useful Improvement in Door Locks and Latches, of which the following is a specification.
The natiu'e of my invention consists in the improved construction and arrangement of the parts of the mechanism of the lock or latch, as hereinafter set forth.
In the accompanying drawings, Figure 1 represents the inner side view of a door lock or latch provided with my improvement. Fig. 2 represents the outer side View of the same. Fig. 3 represents a forward end view. Fig. 4 represents an inner side view of the inner plate of the lock. Fig. 5 represents a vertical section taken in the line 5 5 01 Fig. 3. Fig. 6 represents a horizontal section taken in the line 6 6 of Fig. 3. Fig. 7 represents an enlarged vertical section taken in the line 7 7 of Fig. 6. Fig. 8 represents a horizontal section taken in the line 8 8 of Fig. 7. Fig. 9 represents an enlarged inner side view of a portion of the outer plate to whichthe locking knob is attached, when the outer knob is turned to the position shown in Fig. 7, for the insertion of the key. Fig. 10 represents the same view as in Fig. 9, when the outer knob has been turned to withdraw the latch bolt, and the sliding stop-pin has been pressed inward to prevent the accidental disengagement of the knob from operative connection with the latch bolt. Fig. 11 represents an under View of the slotted cylinder of the outer knob. Fig. 12 represents an enlarged view of the perforated end of the slotted cylinder shown in Fig. 11. Fig. 13
represents a section taken in the line 13 13 of Fig. 7
with the spring removed. Fig. 14 represents a section taken in the line 14 14 of Fig. 7, with the spring removed. Fig. 15 represents a side elevation of the sliding clutch member which is pushed into engagement by means of the key. Fig. 16 represents a section taken in the line 16 16 of Fig. 7. Fig. 17 represents a section taken in the line 17 17 of Fig. 7. Fig. 18 represents a section taken in the line 18 18 of Fig. 7, showing a section of the lock spindle when turned from its normal position by means of the key.
In the drawings, A represents a portion of the stile of the door to which the lock or latch is attached, B represents the cylindrical casing for the latch bolt, and G the latch bolt held for sliding movement within the bore of the said casing.
The side plates D D of the lock or latch, are secured to each other by means of the screws E E, as shown in Figs. 1 and 7, and the inner knob F is provided with.
an opening G of square cross-section, and with the screw-attached collar H, which is held in the circular recess I of the plate D.
The inner end portion a of the knob spindle L, is squared to fit loosely within the squared opening G of the knob F, and the upper side of the said spindle L is provided with the arm M, which enters the slot opening K of the sliding latch-bolt O, as shown in Figs. 5 and 7. The shank Z) of the arm M is held in the longitudinal slot 0 of the spindle L, and by means of the nut (Z upon the shank b, the arm M is made adjustable longitudinally of the spindle L, to provide for the attachment of the lock or latch to doors of different thicknesses.
The outer end of the spindle L is provided with the tongue e, which enters the notch e at the inner end of the sliding clutch member N, the said clutch member being held for sliding movement within the bore of the tube 0. The said tube 0 is rigidly attached to the inner end portion of the outer knob F and also pr'ovided at its under side with a longitudinal slot f, which connects with the transverse slot f as shown in Fig. 11.
The sliding clutch member N is provided at its outer end with an annular flange g, which at the outward position of the said clutch member rests against the inner side of the perforated end h of the tube 0, as shown in Figs. 7 and 8. The clutch member N is also provided with the guiding pin j, which is held for movement in the slot f and f of the tube 0, the said clutch member being actuated in the outward direction by means of the spiral spring P.
The rigidly attached lock case Q, of the outer knob F is provided with the gravitating tumbler pins k k, which serve to prevent the rotary movement of the cylindrical lock spindle R, without the insertion of a properly fitted key S, within the key-receiving passage 1 of the said lock spindle; whereby by means of the tumblers m m, the gravitating pins k It will be raised out of the openings made in the said lockspindle R to receive both the tumblers m m and the said gravitating tumbler pins 70 k, as shown in Fig. 7, so that the said lock cylinder may then be turned to the right hand by means of the key, whereby the prongs n 'n at the forward end of the key S may be caused to enter the perforations 'i i of the tube 0, and then by pushing forward upon the key the prongs n n of the key will engage with the outer end of the clutch member N, and serve to push it into engagement with the tongue e of the spindle L, against the outward action of the spring P. Now upon turning the knob F in the direction of the arrow, shown in Fig. 2, the clutch member N will be prevented from turning with the said knob, by its engagement of the tongue 6 of the spindle L, until the guiding pin 9' which enters the transverse slot f brings up against the end 0 of the said slot, and then the continued turning movement of the knob will serve to cause the retraction of the latch bolt 0, to unlock the door. Now upon turning the knob F in the opposite direction, the clutch member N and the spindle L will be held in engagement until the guiding pin 3" arrives at the longitudinal slot f, and then the action of the spring P will cause the clutch member N to be thrown backward out of engagement with the spindle L, and then the latch bolt G cannot be operated by means of the outer knob without the insertion of the key.
The rotary movement ol the knob F is limitedjoy means of the pin q of the outer plate D and the circumferential recess p, made in the edge of the collar H which collar serves to secure the knob F loosely to the said outer plate. The sliding stop pin T, provided with the head 1", is normally held out of engagement with the circumferential recess 19, as shown in Fig. 9, in which case the fixed pin q will constitute the only limiting factor in the rotation of the knob F v in either direction; but When the stop-pin T is pressed inward, as shown in Fig. 10, the rotary movement of the said knob will be limited in one direction by means of the point 8 oi the said pin, and the knob F will then bemaintained in operative connection with the latch bolt. The lock spindle R is returned from its extreme of rotary movement by means or the spring U, one end of which bears against the pin t of the lock case Q, and the outer end against the shoulder a of the said spindle. The lock case Q is provided with the internal longitudinal groove 1), into which the tumblers m m may be carried when the key S is being withdrawn at the extreme limit of its turned position of the said spindle, as shown in Fig. 18. The latch bolt 0 is locked to its outer position from the inner side of the door, by means of the sliding locking pin V, the point 'w of which enters the recess x made in the side of the latchbolt, as illustrated in Fig. 6.
I claim as my invention 1. In a lock or latch of the character described, the combination of the outer plate, the, outer knob loosely secured to the outer plate, and provided at its inner-end with an attached tube having the connected longitudinal and transverse slots and the perforated outer end, with the tumbler-lock case secured to the knob, the rotary lock spindle held in the lock case, and provided longitudinally with the key-receiving passage which is normally out of line with the perforation in the end of the slotted tube of the knob, the key for turning the key-receiving passage to line with the said perforation, and spring means for imparting the return rotary movement of the lock spindle, to its normal position.
2. In a lock or latch of the character described, the combination of the outer plate, the outer knob, the attached collar provided with the circumferential recess at its edge, and serving to secure the knob loosely to the frame, with the limiting pin for the movement of the knob in either direction, and the sliding stoppin held in the outer plate, and serving to limit the backward rotation of the said knob, whereby the undesired disengagement of the said knob from the latch bolt will be prevented.
3. In a lock or latch of the character described, the combination of the outer plate, the outer knob loosely secured to the outer plate, the tumbler-lock case secured to the knob, the tumbler pins held in the wall of the lock case, the rotary lock spindle held in the lock case and provided with the key-receiving passage, the spring for imparting return rotary movement to the lock spindle, the tumblers held in the lock spindle, and the longitudinal groove made in the bore of the lock case to provide for the withdrawal of the key at its turned position.
4. In a lock or latch of the character described, the combination of the latch bolt provided with the longitudinal slot opening, the cylindrical casing for the latch bolt, the inner plate of the lock or latch, the inner knob loosely secured to the inner plate, the longitudinally slotted spindle adjustably connected with the inner knob, the latch bolt operating arm, having its shank held in the slot of the spindle, and secured therein by a screw means whereby proper adjustment may be' made for doors of dilferent thicknesses.
