OF CHICAGO, ILLINOIS.

DOOR-FASTENER.

Specification of Letters Patent.

Patented Sept. 27, 1910.

.To all whom it may concern:

Be it known that I, CHARLES EY'raLis, a subject of the Czar of Russia, and residing at Chicago, in the county of Cook and` State of Illinois, have invented a new and useful Improvement in Door-Fasteners, of which the following is a complete specification.

Heretofore locks have been employed for sliding doors or windows in which the locking member or latch hook is thrown to locking position by the closing of the door or window, but in those constructions in which the locking member is itself locked against movement when in its closed or locking position, if it should be carelessly or otherwise thrown to locking position while the door or window is open, it must be manually released before the door or window can be closed.

The object of this invention is to provide a lock or latch for sliding doors or windows in which the locking member, if open, is adapted to be thrown to locking position by the closing of the door, and if closed or in locking position, to be automatically thrown out of such position by the closing of the f door and then thrown into locking position as the door reaches its limit of movement.

It is also an object of the invention to provide a lock in which the locking member is secured in locking position by a movable bolt or other suitable memberl which may be manually operated to release the locking member, and which is also provided with means for automatically operating it by the closing of the door.

A further object of the invention is to provide a device in which the latch hook is normally held in open position by the weight of the locking bolt, and which cannot be turned to locking position until suliicient power is applied to it to overcome the weight of the bolt.

The invention consists ofthe matters hereinafter described in the specification and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a front elevation of a lock embodying my invention. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a similar section but showing the door open. Fig. 11 is a horizontal section showing the latch hook in locking position and the bolt actuator retracted, with the bolt in released position. Fig. 5 is a perspective view of the locking hook. Fig. 6 is a perspective view of the bolt actuator. Fig. 7 is a perspective view of the locking bolt. Fig. 8 is a section taken on line 8 8 of Fig. 3. Fig. 9 is a section similar to that of Fig. 8 but showing the catch and actuator open and the bolt retracted to released position. Fig. 10 is a front elevation of a modilied form of the device. Fig. 11 is a section taken on line 11-11 of Fig. 10, but showing the latch hook in open position. Fig. 12 is a perspective view of the latch hook shown in Fig. 10. Fig. 13 is a fragmentary side elevation of the bolt.

As shown in said drawings: A indicates the wall oi" a car or other structure on which the lock is to be used and A indicates a sliding door. Rigidly engaged on the side of the car is the latch hook supporting member or bracket B, which, as shown, comprises an attaching plate b, having its inner end 4 a short distance from the door opening, and against which the forward edge of the door abuts when closed. An arm b2 extends from the end b of said plate to a point approximately flush with the door Opeliing, as shown more clearly in Figs. 2 and 3, and is curved outwardly a suiiicient distance from the wall to permit the edge of the door to pass between the same and the wall. The outer end Z13 of said arm is also curved outwardly to form a detlector or guide adapted to force the door against the wall when being closed. Said arm is provided with a rearwardly opening recess which opens at the front of the arm through a longitudinal slot o4 and in which are pivotally engaged, on a pivot pin b5, the latch hook C and the bolt actuator D. Said hook and actuator extend forwardly a suiiicient distance so that when in closed position, as shown in Figs. 1 to 3 inclusive, their forward ends c and l abut against the forward end of the slot and prevent further inward movement.

i The rear end of the actuator is curved and is provided on its upper face with an incline or cam (Z which extends upwardly and rearwardly to the outer edge of the actuator.

The locking bolt E comprises a rod or bar bent to form a long and a short leg indicated by c and e', and the former of which extends downwardly through a suitable aperture in the arm b2 at the rear of the actuator and latch hook, as shown more clearly in Figs. 2 and 3. The short leg e of said bolt extends downwardly into the recess in the arm b2 and rests upon the rear end of the actuator at the forward end of the cam (Z, when the actuator is in closed position, as shown in Figs. 2 and 3. A notch c is provided in the rear end of the latch hook C into which the lower end of the leg c projects when the hook is in closed position. lWhen the forward end of the actuator is forced outwardly, as shown in lFigs. land 9, the cam d is forced beneath the leg e and raises the same sutliciently to withdraw it from the notch and to permit the rear end of the hook to pass beneath it when the hook is thrown to open position. The inner edges c2 and (Z2 of the rear end of said hook and actuator are `liush with the corresponding face or edge of the arm b2 when said hook and actuator are in their closed positions, as shown in Figs. 2 and 3, but when open said edges project forwardly from the arm into position to be contacted by the door when the latter is being closed. The forward end of the actuator D is provided with a cam surface d, which, when the actuator is in closed position, projects from the inner face of said arm into the path of the door, and the hook C is likewise provided with a cam c3, which does not extend forwardly as far as the cam (Z3 but extends inwardly into the path of the door and at the rear of which is a hook c* adapted to hold the door in closed position. Rigidly engaged on the door A in alinement with said arm is a plate F, the forward end f of which is curved inwardly to provide a contact surface for the cam surfaces e" and (Z3. Back of said inturned end the plate is provided with a transverse slot through which the hook c* and the cam (Z3 project when the door is closed and thereby prevent the door from being opened. If preferred and as shown the latch hook and actuator are provided on their backs with ears c5 having registering apertures therethrough in which a padlock may be engaged to prevent the actuator from being moved.

In the construction shown in Figs. 10 to 13 inclusive, the boltactuator is omitted but the bolt is adapted to prevent the latch hook from turning to closed position by reason of any ordinary jar to which the device may be subjected. However when the door is closed it throws the latch hook to closed position as before described and at the same time throws the bolt to locking position behind th-e latch hook. In this construction the bracket G may be similar to the. bracket B, but as shown ity is adapted to overlap the door stop t against which the forward edge of the door abuts when closed. Pivoted on a pin g passing through parallel ribs g on said bracket, which correspond to the arm 52 in the construction shown in Figs. l to 9 inclusive, is the latch hook H, which as shown is provided with a hook 7L adapted to engage in the plate F as before described. Said latch hook is provided on its inner face, near its rear end, with an arm t, the forward face of which is adapted to be contacted by the door when being closed and the rear of which abuts against the rear end of the slot g2 in said bracket and limits the inward movement of the latch hook. On the rear end of said latch hook is a rearward projection h2, on which is a downwardly inclined cam surface h3. The locking bolt I is similar in construction to the locking bolt E, with the exception that the short leg i thereof is of sufficient length to pass through both ribs g, and together with the leg z' is provided with an aperture 2 beneath said ribs for the seal. Then the latch hook is in closed position the leg z" engages behind the projection lz? and prevents the latch hook from opening as shown in Fig. l0, and when the latch hook is in open position, the lower end of said leg, which is beveled at 2'3 to correspond with the cam surface ha, rests on said cam surface as shown in Fig. ll. The weightof the locking bolt is such that when resting on said cam surface it acts to hold the latch hook against any tendency to close due to jar or vibration.

The operation is as follows: In the construct-ion shown in Figs. l to 9 inclusive, when the door is closed, the locking bolt E is at the inner limit of its movement, with the end of the short leg e inserted in the notch c in the rear end of the latch hook C. Then in this position the hook c* of the` latch hook engages in the slot in the plate F and the door cannot be opened until the bolt is withdrawn sufliciently to remove the leg e from the notch c and release the latch hook. Vhen however the leg e is withdrawn the forward ends of the latch hook and actuator are free to swing outwardly thereby releasing the door. If the latch hook and actuator remain in such position until the door is again closed, the door contacts with the faces or edges 02 and cl2 and swings the latch hook and actuator to closed position and the bolt falls to locking position. If however, for any reason the latch hook and actuator have turned to closed position while the door is open, as shown in Fig. 8, as the door closes, the inturned end f of the plate F first contacts with the cam surface (Z3 and forces the forward end of the actuator outwardly and the rear end thereof inwardly, causing the cam d to raise the bolt and withdraw the leg e from the notch c. The end f then contacts with the cam c3 and forces the forward end of the latch hook outwardly, to permit the door to close.

As the door reaches its closed tion.

posit-ion it swings the latch hook and actuator inwardly and causes the bolt to fall as before described.

The lower end of the leg el may be upset to prevent the bolt from being'removed from the bracket, and is provided beneath the bracket with apertures e4 and e5 adapted to receive a seal or lock to prevent the bolt from being retracted when in locking posi- The outward movement of the actuator is limited by the leg e which forms a stop against which the rear outer corner of the actuator abuts when the actuator is fully retracted, and the movement of the latch hook is likewise limited by the cam d.

In the construction shown in Figs. l0 to 13 inclusive, the latch hook is thrown to locking position by the closing of the door as before described. As said latch hook swings to closed position the bolt is raised by the cam 71.3 and as the projection /L2 passes from beneath the leg c" the bolt falls and locks the latch hook in closed position. The weight of the bolt is sufficient to hold the catch open when the leg z" is resting on said cam, and the latch hook cannot close until suliicient force is applied to it to overcome the weight of the` bolt. Then it is desired to release the latch hook the bolt is raised sufficiently to permit the projection 71,2 to pass beneath the leg z".

Obviously a device constructed in accordance with my invention alfords a very quick acting and effective lock for sliding doors or the like.
