At one end 45' showing the position of the parts the instant of said latch is provided a perforation a, 5 the parts have been released by the time having about it a boss portion a and at its mechanism to retract the door-bolts; Fig. 10, other end a portion is cut away to form a a plan view of the cap or cover provided to graded portion 1), and on the lower front end protect the parts. Fig. 11 is a perspective of portion of said latch is provided a toe b, as
go the sliding-plate latch; Figs. 12 and 13, simishown in Fig. 11. The latch G is placed in 7 right the distance of the throw of the bolt,
the raceway a and the spindle a passed through the aperture 0., the free end in the raceway.
To the face of the case A, below the raceway, is pivotally secured a detent-lever H, and above said raceway a releasing-lever L. The said levers may be of the form substantially as shown, the lever H having a perforation b and a detent-hook b to engage the toe b of the latch G, the free end portion b to take under the restraining-lever J, as shown in Figs. 7 and 9.
The lock-lever K is provided at its lower end portionwith an inwardly-proj ected stud-pin I), (see Fig. 14,) and at its upper end portion with an elongated aperture b. The time-lock-actuated lever L is of the form shown, having a heel portion 6 having therein a perforation b a handle portion b and a toe portion 12 having a perforation d. The lever L is pivotally secured to the case A by the screw d, as shown, and the toe loosely secured to the locking-leverKbythe screw d passed through the'aperture b into the perforation d to form a sliding engagement between the lockinglever K and the releasing-lever L.
A spring-actuated finger N is pivotally secured to the top portion of the case, as shown in Figs. 2,3, 7, and 9. In this case the spring is concealed under the body portion of the finger coiled about the screw d by which the finger is pivoted to the case, the energy of said spring being exerted to press the finger against the lever L.
To compress or wind the casting and retracting springs, a toothed rack M is secured to the face of the case A, as shown in Figs. 1, 7, and 9. A winding-key P, as shown in Fig. 8, is provided. having stem and handle, portions d and 1 and a winding-pinion Q, having peripheral teeth d adapted to engage similar teeth 61 of the rack M, and a central perforation d In operation, to compress the springs the pinion Q is placed on the pin or stud a, the teeth (1 of the pinion Q engaging the teeth 61 of the rack M. The handle turned from right to left will rotate the pinion about the pin a by which movement the pinion and the sliding plate will be carried from left to and with the sliding plate the latch G is carried into engagement with the detent-hook b at the end portion of the lever H, as shown in Fig. 7, at which point the pinion is withdrawn. By this arrangement of the spring winding or compressing devices 011 the outside of the inclosing-case A the case may be shortened without encroachment upon the length or efficiency of the casting or retracting springs or the lockbolt. It will be evident that a much smaller form of lock may be constructed, adapted for use on small doors, and yet retain the usual size of all of the actuating or working parts of the look.
When the time mechanism R shall have reached a period previously determined upon,
the pendant 01 will engage the releasing-lever L and press it over to position shown in Fig. 9, at which instant the restraining-lever J will be released from the stud b on the locking-lever K, at which instant the sliding plate 13 will be carried from right to left. To retract the door-bolts, the levers H and J take for an instant the position shown in Fig. 9, and will drop back into the position shown in Fig. 7 ,and thelooking and releasing levers will remain in the position shown in Fig. 9 until the time mechanism is again wound and the springs compressed, when they too will take the position shown in Fig. 7 and again hold the spring compressed for another period of time. When the parts have been moved to the position shown in Fig. 9, the levers J and H are caused to assume the position shown in Fig. 7 by the boss a hereinbefore referred to, which travels in the track of the lever J,
whenthe sliding plate is shot and forces the said lever downward beneath the lug b before the lever K has time to return to the position shown in Fig. 7, thus resetting the said levers. It has been discovered, however, that in some instances the lever K after the bolts have been shot is forced from its position shown in Fig. 9 to its position shown in Fig. 7 by the spring-actuated releasing-lever L, and in this event the lever J is unable to reach a point below and engage the under side of the lug b to lock the said levers when the springs are compressed. In other words, the lever J must be held against vertical movement by the lug b to retain the lever H in locked position against theaction of the springs when compressed, this being the object of resetting the levers when the sliding plate is shot. To provide a positive means for causing the lever to assume its position beneath the lug W, as shown in Fig. 7, I enlarge said lever by a graded portion 01 (shown in dotted lines in Fig. 7,) which, should the lever fall with its free end upon the upper surface of the lug aforesaid, will be engaged by the boss a which will force the free end of the said lever, which may be slightly rounded against the lug, which, with its lever K, will be moved slightly to one side and permit the lever J to drop beneath the lug, which, through the action of the springactuated releasing-lever L .and the lever K, will return to its position above the lever J and hold it against vertical movement. It will therefore be seen that I provide a positive means for resetting the levers.
It will be observed that when the releasing-lever L is thrown by the time or other actuating mechanism into a position to release the sliding plate, and hence the lockingbolts, the same stroke of the lever will throw the parts into such position that a locking of the bolts cannot be effected until the same lever shall have been positively and intentionally again moved. The door-bolts (shown in Fig. 1) and the manner of operating them is similar to that shown and described in my application filed on the 20th day of February, 1890, Serial No. 341,237.
The cap S is provided to cover and protect the detent and other levers, hereinbefore mentioned.
A detent T is loosely secured to the plate U, the head portion it having dropped into position, as shown, in front of the plate E in the line of its movement, and the tail portion 71 projected outwardly to meet the door-jam, by which the detent will be rocked in its pivotal connection with the supporting-plate U.
It will be observed that the spring-compressing devices and the devices for holding and re leasing said springs are located outside of the case, and by thus locating the parts access may more readily be gained to them for any purpose whatever-such, for instance, as to repair or remove the parts or for cleaning or lubricating them. Thus the obstacles heretofore experienced in devices of this character wherein the mechanism above mentioned is inclosed in the casing adjacent the springs are entirely overcome.
In operation the time mechanism is wound and set, and the casting and retracting spring compressed, as before stated, the detent T engaging and resisting the movement of the door-bolts until the door is closed. The tail k engaging the door-jamb will swing the detent out of engagement with the plate E, when the casting-springs will cast the door-bolts into engagement with the door-jambs, in which position they will remain until the retractingsprings are released by the time mechanism, when the bolts will be disengaged from the door-jamb and the door unlocked.
Having thus fully described the nature and object of my invention, what I claim, and desire to secure by Letters Patent, is
1. The combination, with the bolts of a safedoor, of springs for casting and retracting the bolts, a sliding plate against which the springs act, and a spring-compressing device located outside of the case, comprising a stationary rack-bar and a pinion having a bearing on the sliding plate, the teeth of said pinion engaging the teeth of the rack-bar and adapted to be rotated about its bearing and to travel longitudinally with said plate, substantially as set forth.
