DOOR-LOCK.
Specification of Letters Patent.
Patented Jan. 12, 1915.
Application filed April 22, 1914. Serial No. 833,637.
To all whom it may concern:
Be it known that I, FRANK BENNETT, a citizen of the United States, and a resident of Delmar, in the county of Albany and State of New York, have invented a new and Improved Door-Lock, of which the following is a full, clear, and exact description.
This invention relates to builders hardware and has particular reference to looks and latches.
Among the objects of the invention is to simplify and improve that class of door locks known as mortise locks and provided with means for operation from either side of the door.
Another object of the invention is to provide a lock of such a nature that the knob shaft may be either pulled or pushed for releasing the latch without rotating it, while provision is made for the latch to be released in the usual manner by rotation of the knob shaft irrespective of the expedient for releasing the latch by pull or push.
A still further object of the invention is to provide for the reversal of certain of the parts of the latch so as to adapt the latch for use in connection with doors swinging in opposite directions.
The foregoing and other objects of the in vention will hereinafter be more fully set forth and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which-- Figure 1 is a view of a mortise lock, the face plate being removed, showing one form of the invention and so arranged that the latch bolt will be released either by rotation of the knob shaft in either direction or by a push of the knob shaft without rotation, the door being understood to be adapted to swing open away from the observer; Fig. 2 is a similar view of the same device showing a change in position of the parts due to a direct push upon the knob; Fig. 3 is a view similar to Fig. 2 but indicating the reversal of certain of the parts of the lock for application to a door designed to swing in the opposite direction or toward the observer; Fig. 4 is a horizontal section on the line 14: of Fig. 1, showing the parts in normal position; and Fig. 5 is a similar view on the line 5-5 of Fig. 3.
The several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully described and claimed.
Referring to Figs. 1, 2 and 4: I show a lock casing 10 of any suitable construction having a face plate 11 secured in place in the usual manner by screws or rivets.
A hub 12 is fitted in the casing and is provided with a main portion having a cylindrical exterior surface adapted to rotate in or slide bodily through the bearing hole 13 in either the fixed plate or the face plate, according to the adjustment of the parts. Said hub also comprises a pair of lugs 14 extending in opposite directions and substan tially tangentially from the end of the cylindrical part of the hub. Said lugs 14119111 the same plane. The hub is adapted for cooperation with the square knob shaft -15 as usual.
One of the principal parts of the improvement comprises a lever 16 pivotally mounted at one end upon a fixed pin or stud 17 and having its other end loosely connected to a pivot 18 on the latch bolt 19. The end of the lever just referred to is offset as shown at 20 to accommodate the pivoted end of the bolt 19. As stated above, the pivot connections 17 and 18 being loose,
provide for the removal of the detachable parts for reversal as, for instance, from the position shown in Fig. 1 to that shown in Fig. 2; that is to say, in making such change the end of the lever at the pivot 17 becomes the end for the connection of the bolt, as shown in Fig. 3, by simply turning the lever end to end. Precisely midway, therefore, of the lever there is provided a recess or notch 21 for the accommodation of the hub 12 when the parts are held in the normalposi tion indicated by virtue of any suitable form of spring 22. On each side of the recess 21 is formed a beveled shoulder 23 having a peculiar correlation with the hub lugs 14. When, for instance, the knob shaft 15 is rotated, one or the other of the lugs 14, depending upon the direction of rotation, will cause the swinging ofthe lever 16 around its pivot 17, causing the latch bolt 19 to be released from the striking plate (not shown). It will be apparent, therefore, that this latch may be actuated in the usual manher by rotation'of either knob in either direction as usual. If, however, a person is approaching the door, and with his hands so filled as to make it inexpedient for him to grasp the knob, he may push against the knob as indicated in the direction of the arrow, Fig. 4c, and cause the hub 12 to be pushed bodily by contact therewith of a shoulder 24 which consitutes the opposite bearing for the hub in the casing. This di rect thrust upon the knob shaft, either by a push on the one knob or a pull on the other, causes the hub lugs 14: to act upon the bevels 23 and thereby cause the lever to swing against the tension of the spring 22 with a similar action upon the bolt 19. The longitudinal thrust of the shaft 15 and hub 12 is normally resisted by some suitable spring devices herein shown as comprising a leaf spring 25 adapted to bear at its free end against the inner face of the flange 14: from which the end lugs 1 1- project. The spring 25 has no particular effect when the knobs are rotated, the free end of the spring simply playing around the cylindrical portion of the hub. The opposite end of the spring 25 is connected detachably by means of a screw 26 or the like to either the main portion of the casing or the face plate 11, according to the way in which the device is adjusted, as shown by comparing Figs. i and 5,. The term knobs as used herein, will be understood as being sufiiciently generic to cover any suitable means to cause actuation of the latch bolt 19 from either side of the door.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The herein described door lock comprising, in combination, a casing, a latch bolt adapted to reciprocate in said casing, a knob shaft adapted to rotate and reciprocate through said casing, a hub fitted to the shaft, said hub having a flange formed at one end thereof and a pair of lugs at the ends of said flange, a spring acting upon said hub flange and holding the hub normally within the casing, a lever detachably pivoted at one end upon a fixed pivot and having its other end pivoted to said bolt, the middle portion of the lever being recessed to receive the hub and knob shaft, the shoulders at the sides of the recess being beveled for cooperation with said hub lugs, and means acting upon the lever to hold the bolt normally projected.
2. The herein described lock mechanism comprising, in combination, a casing having a rigid face plate fitted with a pivot stud and a bearing hole, a removable face plate provided with a similar bearing hole in axial alinement with the other hole, a straight lever removably pivoted on said fixed pivot stud at one end, a latch bolt adapted to reciprocate in the casing and having its inner end detachably pivoted to the opposite end of the lever, the lever being reversible whereby either end thereof may be connected to the fixed stud, and the middle portion of the lever being notched and the shoulders on opposite sides of the notch being beveled in the same plane, a hub mounted in the casing, the end of the hub being cylindrical and journaled in one of said holes, a knob shaft fitted through the hub and having a shoulder abutting against the opposite end of the-hub and journaled in the other of said holes, said hub being provided with bearing lugs cooperating with said bevels, and means acting normally upon the hub and lever serving to hold the parts in normal position with the bolt projected.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRANK BENNETT.
