LOCK MECHANISM.
Specification of Letters Patent.
Patented Jan. 26, 1915.
Original application filed. March 24, 1913, Serial No. 756,366. Divided and this application filed February 25, 1914. Serial No. 820,838.
To all whom it may concern Be it known that I, GEORGE E. CLEAVER, a citizen of the United States, and resident of Reading, county of Berks, and State of Pennsylvania, have invented an Improvement in Look Mechanism, of which the following is a specification.
My invention relates to improvements in looks, and more particularly to the stop mechanism and its associated parts for controlling the latch operating knob hub; and the present application is filed as a division of application Serial No. 756,366, filed March 24th, 1913.
The invention has for an object, to provide a stop mechanism for dead-locking the knob hub or hubs; and where the hub structure is formed as a split hub, the stop mechanism embodying my invention may be arranged to control either one of the split hubs in an effective manner and without requiring a reversal of the hubs.
My invention has for a further object, to provide a means for automatically actuating the stop mechanism to prevent the latch being operated by the outer knob when the locking dead bolt is protracted.
My invention consists in certain features of construction whereby the stop members are identical and are so combined with a connecting pivoted stop beam lever and stop plunger that said parts may be assembled, without special work, to suit either right or left hand use of the lock; and further consists of means connecting with the dead bolt whereby the projection thereof into locking position positively insures the stop plunger being moved automatically into locking engagement with the knob hub to hold it against movement.
My improvement will be described with reference to the accompanying drawings, which illustrate my invention in its preferred form, while the features of construction and combination of parts adapted for carrying out the invention in an eflective manner will be fully set forth hereinafter, and more particularly defined in the claims.
Referring to the drawings: Figure 1 represents a side elevation of a portion of the lock proper, with a portion of the side plate .removed and the front plate in section, to
show the stop members and their associated parts, constituting the dead-lock for the knob hub employed for operating the latch bolt; Fig. 2 represents a transverse section on line mc0 of Fig. 1; and Fig. 3 repre sents the members of the stop mechanism in perspective.
Similar numerals of reference indicate corresponding parts.
1 designates a box portion of the lock case which, as generally arranged, is secured to the front plate 2, and is provided with a removable side plate 3 through which access 1s had to the mechanism contained within the case, and by which said mecha nism is protected when the lock is in use.
1 designates the latch bolt body which, as customary, is mounted for sliding movement through the front plate 2 and has the tail piece 5 thereof provided with lateral projections 6 upon each side and serving as guide means acting against the side of the case.
7 designates a coil spring suitably mounted with respect to the latch and serving as a means to protract the latch bolt and main tain the parts in operative relation, as will be understood.
8 designates the knob hub lever which is pivoted to the case and normally held out of action in respect to the tail piece 5 by a spring 9, so that its free end rests under one of the lateral projections 6 of the latch bolt whereby it may be retracted by the operation of the door knob.
The lever 8 has a portion 10 which normally acts as a stationary guide lug for the under portion of the tail piece of the latch bolt, while the fixed lug 11 on the case acts to guide the upper portion thereof when it is withdrawn by means other than the door knob, as for instance by the mechanism operated by the key or turn hub usually employed in fine looks. The lever 8 also acts as a moving guide for the tail piece of the latch bolt, in conjunction with the fixed guide lug 11, at the time the door knob is being turned to withdraw or retract the latch bolt.
The knob lever 8 is operated by the split knob hub parts 12 and 13 which are journaled in the case and upon each other, and are provided With square holes 14: for the knob spindle or spindles in order that they may be properly rotated. As a means for dead-locking either of the hub parts, each is provided with a notch 15 adapted to receive the dead locking stop plunger 16 which is operated by the other members of the stop mechanism. 7 This mechanism embodies two stops 17 and 18, made alike, and working through apertures in the front plate 2 of the case. The inner ends of these stops have transverse pins 19 and 20 which respectively fit in openings formed on opposite ends of the stop beam lever 21, the latter being pivoted at 22 to the lock case. The stop plunger 16 is guided in guides 23 close to the hub parts 12 and 13, and the other end is provided with an opening 21 fitting upon the pin 19 of the stop 17 In this way, the knob hub part may be deadlocked or dogged by a construction which is simple, cheap and durable, and so formed as to enable its parts to be interchangeable. It will further be noted that the stop plunger 16 is notched as shown at 25 in order not to interfere with the free operation of the knob hub part 12, which, for example, would be operated by the door handle on the inside of the door. The stop beam lever 21 connects the stops 17 and 18,
so that simultaneous reversed movement to them may be effected, while the operation of the stop plunger 16 to lock the hub is direct and positive from the stop 17. The end of the stop beam lever 21 is preferably made annular as shown at 26 to receive the end of a spring 27 which acts to normally hold the lever in its two extreme positions of adjustment.
By the construction of stop mechanism here described, the plunger 16 may be readily reversed to deadlockeither of the spht hub parts 12 or 13, and thereby do away with the heretofore more or IGSSHHSELUS- factory mode of fitting and reversing such a hub. These improvements also allow of more quick and positive reversing ad ust ment. The jointing of the long or looking stop formed of the parts 16 and 17 enables the plunger part to be made of inflexible and cheap cast iron or other cheap metal, while the protruding stop part 17 having the head can be of the usual more costly brass or bronze; this construction also securing the positive action of the stop plunger substantially as well as if it were made as an integral part of the stop.
28 designates a lever suitably pivoted to the casing and having one end located in the path of the plunger 16, while its opposite end is arranged to be acted upon by the dead bolt 30 shown partly in dotted lines, the function being to provide a means for dogging the stop mechanism so that the stops l7 and 18 are rendered inoperative and cannot be successfully tampered with when the dead bolt is protracted, and more over, the stop plunger automatically moved into dogging position to prevent the outer door knob from being turned. The lower end of this lever 28 engages the shoulder 29 of the stop plunger 16, and when the dead bolt 30 is protracted its lug 31 acts to shift the lever 28, and the stop plunger is automatically moved into digging or looking position to lock the knob hub part 13 as aforesaid. When the dead bolt is retracted there is no effect upon the stop mechanism owing to the loose play of the lever 28, and the stops may then be adjusted by hand. The protraction of the dead bolt, therefore, always looks or dogs the outer knob (in case this knob has not been previously set by hand), thus always insuring that when the dead bolt is in looking position, the door also has its protection of the latch bolt as well, as far as knob operation is concerned. The retraction of the dead bolt does not unset the stops; therefore the stops are manually operated when it is desired that the outer knob be free to operate the latch bolt.
It will be understood that, in the better class of door locks, the outer and inner door knobs are independent so that the inner knob may always be operated to withdraw the latch bolt, even when the outer knob is dogged or held against movement, and this is intended to be so in the most preferred form of my invention; but it is evident that it is not essential to have the knobs independent in action and hence it is to be understood that, if desired, the two knob hub parts may be cast integral and a solid spindlel employed, as is common in the cheaper loo (S.
Having thus described my invention, what I claim and desire to protect by Letters Patent is;
1'. In a lock, the case and latch bolt, combined with the latch lever, the knob hub, a stop plunger to lock the hub, and stop mechanism for operating the stop plunger con sisting of a beam lever pivoted to the case and having holes at each end, and stop members extending through the end of the case and having inwardly extending arms provided with transverse pins respectively fitting the holes in the ends of the pivoted beam lever, one of said stop members also having its pin forming a jointed connection with the stop plunger.
2. In a lock, the case and latch bolt, combined with the latch lever, two knob hubs arranged in the same alinement and each having a locking notch, a stop plunger formed of a reversible bar having locking projection adjacent to one edge only, said plunger reversible to lock either of the hubs, and stop mechanism for operating the stop plunger consisting of a beam lever pivoted to the case and having holes at each end, and stop members extending through the end of the case and having inwardly extending arms provided with transverse pins respectively fitting the holes in the ends of the pivoted beam lever, one of said stop members Copies members, the beam lever and stop plunger whereby either stop member may beinterchanged with the other or reversed in its 15 operative position to maintain operative relation with the stop plunger.
In testimony of which invention, I hereunto set my hand.
