DOOR-SECURING MEANS.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed August 4, 1904. Serial No. 219,436.

To all whom, it may concern:

Be it known thatI, LIBERMOND A. LEON, a citizen of the Republic of France, residing in the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Door-Securing Means; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to door-locks; and it consists in certain features of novelty in the detail construction, arrangement, and operation of the several parts relating thereto, whereby a lock is provided which may be used as a temporary lock to be operated by means of an ordinary latch and knob, or which may be so set as to be operated electrically for the purpose of releasement, and which may also be locked so that without the electrical connections the lock may be operated by means of an ordinary key, if desired.

The object of the invention is to produce a device of the character described which will be simple in construction and which will provide such cooperative parts as will render it certain in operation, all as hereinafter more fully described, and specifically pointed out in the claims.

In the annexed drawings, in which similar numerals of reference indicate corresponding parts in all the views, Figure 1 is an elevational view of a part of a door and door-stile to which my invention is attached, with the operative mechanism shown in full lines, with the door-latch closed and locked in a closed position. Fig. 2 is a view similar to Fig. 1, except that in full lines the locking means which, as will be evident, comprise also the releasing means are placed in an abnormal position for the purpose of releasing the latch. Fig. 3 is a detached fragmentary view illustrating a portion of the door, showing the face-plate of the lock. Fig. 4 is a sectional view taken on the line 4 4: of Fig. 1 looking in the direction indicated by the arrow. Fig. 5 is a sectional view taken on line 5 5 of Fig. 1 looking in the same direction. Fig. 6 is a view looking toward the door-stile with a portion of the stile broken away for the purpose of showing the location of the parts illustrated in such figure therein. Fig. 7is a detail View showing a locking means for rendering the electrically operated lock hereinafter described inoperative. Fig. 8 is a sectional view taken approximately on the line 8 8 of Fig. 1. Fig. 9 is a detached perspective view of the rear face of the pivoted latch hereinafter described. Fig. 10 is an elevational view shown partly in full lines and partly in dotted lines, showing my improved locking means as formed when adapted to be used in conjunction with an ordinary springactuated latch with a cam-face, as shown in Fig. 11. Fig.

.11 is a sectional view taken approximately on the line 11 11 of Fig. 10; and Fig. 12 is a View showing the interior of the door-lock-that is, the lock which is attached to the face of the door as distinguished from the stileillustrating the means for locking the gravity-latch hereinafter referred to in position.

As indicated by the reference-numerals, 1 is a door, which is provided with the necessary recesses in the inner face thereof, as shown in the sectional view, Fig. 5, so that the lockplate 2 may be slidably connected therewith, said lock-plate engaging with the journalguideways 3, as best shown in said Fig. 5, to secure the look-plate and appurtenant connections in position. Supported upon the spindle 4 is a pivoted gravity-latch 5, which, as shown in the detached detail view, Fig. 9, is provided on its inner face with the angular projections 6, comprising eyelets or loops, by means of which the said latch may be locked in position upon thrusting the lockingbolts 7 into an outward or abnormal position within the cavities 8 of the lock, whereby, if desired, keys may be inserted in the keyholes 9 (shown in Fig. 12) for projecting said bolts upwardly, and thereby lock the said latch 5 in position to engage with the strike 10, which strike constitutes an engaging hook for holding said latch and preventing the door 1 being opened except when the latch 5 is raised. As will be noted in Fig. 5, a stud 11, with an en larged head on the outer end thereof, is projected into the socket 4, and said stud has slots 12 therein with which the hook 13 is adapted to engage for the purpose of holding said stud in position to hold the latch 5 upon the face-plate 2, said hook 13 being pivotally supported upon the stud 14, whereat the hook is provided with the slots 15, which are adapted for the insertion of a key, so that said hook 13 may be rocked upon its pivot to bring it into engagement with the slots in said stud 11.

Pivotally supported upon the studs 16 is a gravity-trip, (indicated generally by the reference-numeral 17,) said trip having, as shown, the lower nose portion 18, which is adapted to strike the lower end of the block 19 or the coincident portion of the latch, said block being held upon the latch for the purpose of raising said block, and with it said latch, when the said trip is thrown to the position shown in full and dotted lines in Fig. 2, in which figure the latch 5 is elevated by means of said trip. As will be noted, the trip 17 is curved for a portion of its length, whereby the seat 20 is provided, with which seat contacts the pin 21 when the latch is in its lowermost that is, its normalposition, the said pin being provided to prevent excessive outward movement of said trip away from the door. Pivotally supported in a position to rest relatively above the block 19 is a gravity-lock 22, which is provided with the angularly-extending nose portion 23, as shown in Fig. 1,which nose portion or shoulder is adapted to rest above the upper face of said block 19 and when the tripisin the position shown in Fig. 1 prevent upward movement of the latch to release it from the hook or strike 10. Projecting from the trip 17 is an arm 24, which normally rests under the arm of the gravity-lock 22, so that a forward movement of the trip 17 in a direction toward the door will cause'the arm 24 to strike the opposing arm 25 and rock the gravity-loek 22 upon its pivot 26, thereby withdrawing the shoulder 23 from above the said block 19 and permitting the latch 5 to be raised. The trip 17 is also provided with an upwardly-curved extension terminating in the anvil portion 27, which, as shown, comprises the enlarged rounded end thereof. Supported in convenient relation to the anvil 27 is a gravity-hammer, which is pivoted upon the pin 28 and is locked thereupon by means of the key 29, similar keys being provided for the members 17 and 22 to prevent said members being displaced from their pivotal supports. The gravity-hammer, as will be noted, is curved, whereby a seat 30 is provided with which contacts the pin 31, which pin serves to limit the movement of said hammer in a direction toward the door 1, such stop being necessary to prevent the hammer passing the center of gravity and falling to a position which would displace the operative mechanism of the structure. Thehalnmer 32 is provided with a head portion 33, which, as will be noted, has upon the upper side thereof nearer the door the shoulder 34, with which is adapted to engage another gravity-lock 35, said lock being provided with a nose portion 36 extending downwardly therefrom,said nose portion being adapted to engage said shoulder 34, and thereby hold the hammer 32 temporarily in its extreme raised position. The member is pivoted at 37 and is provided with a downwardly-extending arm 38, which is adapted to contact with the stop 39 upon the rod 40, which rod 40 terminates in the friction-reducing roller 41, said roller projecting from the stile or door-jamb into the path of the door to a limited extent, where it is adapted to be impinged by the plate 42 (best shown in Fig. 8) for the purpose of projecting said rod 40 in the direction indicated by the arrow in that figure when the door is closing, whereupon the stop 39 will contact with the arm 38, and thereby raise the upper lock 35 to the position shown in full lines in Figs. 1 and 10, when the door is closed. However, when the door is open it will be evident that the weight of the member 35 will bear against said stop 39, and thereby project the said roller outwardly into the path of the door, as shown in full lines in Fig. 7, thus placing the hook 36 in position to engage with the shoulder 34 of the hammer 32 when said hammer is being raised. Opposite the shoulder 34 the head 33 is provided with an upwardly-extending shoulder, which is adapted to engage with a lug 43 on the armature 44 so as to serve as a permanent means forholding the hammer 32 in an upper position when the door is closed. In convenient relation to the armature 34 are electromagnets 45, connected by means of a suitable circuit with the battery 46, from which battery may extend wires to any convenient part of the building for conducting circuit, and push-buttons may' be provided in such circuit to close the circuit when desired for the purpose of actuating the armature to release the hammer.

The lower end of the hammer 32 is provided with a laterally-projecting stud 47,

which is slidably mounted within the link 48, said link being provided with a slot 49 therefor and being pivoted upon the stud 50, while the opposite arm of said link is provided with a slot 51, with which engages the pin 52 on the vertically-reciprocatory rod 54, as shown, said rod terminating in aslide 55 at its lower end, which slide is pivotally connected with the rod 54, and said slide is guidedbetween the ways 56 and 56 to preserve the relative perpendicularity thereof. The rod 54 extends thence upwardly and is connected with the lower crank-arm 57 of the rockable lever 58, which lever is pivoted at 59 in the casing 60 and is pivotally connected at its upper end with the horiZontally-reciprocatory rod 61, which rod is guided between friction-rollers 62, supported by means of the plates 63, so that torsional disturbance of said rod is avoided. The opposite end of said rod is provided with the beveled faces 64 and 64, adapted to contact with the friction-roller 65, which is supported in the yoke 65, said yoke 65 be- 4 pivot 28.

ing attached to the upper edge of the door 1, so that as the door is opened the roller 65 will ride up the inclined face 64, thereby projecting the rod 61 in the direction indicated by the arrow in Fig. 1, whereupon the arm 58 is rocked upon its pivot and the rod 54 is drawn vertically upwardly. On drawing the rod 54 upwardly the pin 52 engages the slot 51, thereby rocking the link 48 upon its pivot and projecting downwardly the arm thereof which has the slot 49, whereupon such arm will engage the projection 47 of the hammer 32 and cause said hammer to rock upon its When this occurs, the upper gravity-lock 35 will assume the position shown in dotted lines in Fig. 2, thereby locking the hammer in an abnormal position of temporary rest, where such hammer is held until the door 1 is again closed, whereupon the stop 39 will impinge the arm 38, and thereby raise the member 35 to the position shown in the full lines in Fig. 1, whereupon the hammerhead 33 will by gravity fall into contact with the lug 43 upon the armature 44, which, as will be noted, provides only a slight contact between such parts, so that but a minimum of pull by the magnets will be required to withdraw the armature and release the lug 43 from engagement with the hammer-head. In closing the door it is evident that the roller 65 will impinge the beveled face 64, and thereby cause a slight movement of said rod 61, but not sufficient to release any of the associated parts thereby.

Referring now to Fig. 10, the trip 17 is displaced by a trip 17, which is formed similarly to the said trip 17 except that the arm 24 is not made a part thereof; but the end 18 is adapted to contact with a push-rod 66, (shown in Fig. 11,) which push-rod is provided with the enlarged head portion 67, which head portion is adapted to ride into and approximately fill the opening 68 in the casing 69, so as to contact with a reciprocatory latch 5, which is shown diagrammatically in Fig. 11, so that the latch is retracted in the structure shown in Fig. 10 when the extension 18 contacts with the rod 66.

It will be evident that where the modification of Figs. 10 and 11 is used an ordinary spring door-latch may be substituted for the gravity-latch 5 of the other figures.

The armature 44, as will be noted, is carried by the rod 70, which rod is pivotally supported. at 71 above the stop 72, which stop prevents excessive downward movement of the armature, which would have a tendency to carry it away from the influence of the magnets 45. As will be noted, the lug 43 is normally in a position to engage the hammerhead 33. To permit said hammer-head to rise and pass the lug 43, such lug is pivotally supported in the lower portion of the armature, so that it may swing to the position shown in dotted lines in Fig. 10 when the hammer-head is being raised past the said lug, thereby providing a clearance for the hammer-head at this time, after which the lug will drop by gravity to the position shown in full lines in the drawings.

In Fig. 1 there will be seen a lock 74,which lock comprises a serrated cam member having the projection 75 integral therewith, which projection is adapted to interlock with the recess 76 in the spring-actuated arm 77, said arm being pivoted at 78, and by means of a spring 79 being projected normally in a position to engage with the said member 74. The member 74 is provided with slots 80, adapted to receive a key, so that the said serrated cam may be rocked upon its pivot 81, thereby bringing the projection 75 into the said seat 76 and carrying the upper end of the arm 77 outwardly, as best shown in Fig. 7, in which figure it will be noted that the upper end of the arm 77 contacts with the lower end of the hammer 32, and thereby locks the said hammer in its uppermost position, so that even if circuit is closed through the battery the position of the members comprising the lock for the door will not be disturbed, owing to the fact that the hammer will not be released to contact with the'anvil 27 of the trip.

As will be noted in Figs. 1 and 4, the arm 61 is joined intermediate its length and the pin 61 is projected through coincident openings in the two arm-sections to unite them together, while a plurality of such openings are provided, so as to permit of longitudinal extension or contraction of said arm 61, as may sometimes be necessary.

The operation of my improved lock is as follows: The operative mechanism is preferably inclosed within suitable casings, which are adapted to be slid into recesses provided therefor within the door-frame and within the door and fixed in position therein, as shown, after which the necessary connections are made, so that when the door is opened the roller 65 will impinge the beveled end of the rod 61 and rock the arm 58, thereby raising the rod 54 and setting the hammer to an upper position, where it is held temporarily by the upper gravity-lock 35., after which the door may be closed, whereupon the door will cause releasement of the upper gravity-lock and permit the hammer to assume the position shown in Figs. 1 and 10. As the rod 70 is pivoted at 71 and carries at its opposite end the armature 44, it is evident that the line of movement of the armature and arm 70 must be from the point 71 as a center. The hammer being pivoted at 28, it is evident that said hammer must move from the point 28 as a center, and the curve of these arcs is such that the hammer 33 may strike the lug 43 on the armature without moving the armature toward the magnet.

Thus when the lock 35 is released it will be evident that the hammer cannot move the armature on its pivot and continue this movement past said armature. When in any manner the circuit is closed between the battery and the magnet, the armature will be drawn upwardly by means of said magnets, thereby raising the lug 43 out of the path of the hammer-head 33 and permitting the same to fall by gravity upon the anvil 27, whereupon the lower end 18 of the trip will impinge either the block 19 or the latch 5, thereby raising such latch from engagement with the strike 10, whereupon the door may be opened, or if the modification shown in Fig. 10 is used the end 18 of the trip 17 will impinge the rod 66, which in turn will drive the reciprocatory latch 5 into its seat and release the same from engagement with the strike upon the jamb. When it is desired to place the releasing mechanism out of connection, the serrated cam-lock 74 may be rotated to lock the arm 77 against the lower end of the hammer, and thus it will be evident that the magnet may be energized without causing the mechanism to operate to release the door. This condition is desirable on some occasions, as during the night, when the inmates of the house do not wish the door to be used.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
