Specification of Letters Patent.
Patented Aug. 8, 1911.
Application filed August 4, 1910. vSerial No. 575,440.
To all whom it may concern:
Be it known that I, JAMES; C. Lonen, a citizen of the United States, residing` at Vilmington, in the county of New I-Ianover and State of North Carolina, have invented certain new and useful Improvements in Locks, of which the following is a specification.
My invention relates to locks and particularly to locks of the gravity type.
An important object of this invention is to provide a gravity lock,-which is formed of few and simple parts, and which parts cannot be actuated by an improper key.
Other objects and advantages `of my invention will be apparent in the course of the following description.
In the accompanyingdrawings, forming a part of this specification, and in which like numerals are employed to-designate like parts throughoutthe same, Figure 1 is a side view of my lock, one side of the casing being removed, Fig. 2 is a vertical crosssectional view taken on line 2--2 of Fig. 1, Fig. 3 is a side view ofthe key for moving the tumbler, Fig. 4 is an enlarged detail sectional view through the locking mechanism for the bolts, taken on line 4-4 of Fig. 1, Fig. 5 is a side view of the key to coperate with said locking mechanism,:Fig. 6 is a side View of a modified form of lock and showing one side `of the casing removed, Fig. 7 is a vertical cross-sectional view taken on line 7-7 of Fig. 6, Fig. 8 is a side view of a key to coperate with the form of lock shown in Figs. 6 and 7, Fig. 9 is a view similar to Fig. 7, and showing the lock provided with an extended spindle for carrying a handle, and Fig. 10 is a side view of a` key to be used in connection with the form of lock shown in Fig. 9.
The form of lock shown in Figs. 1 to 5, inclusive, is particularly well adapted for use upon safety deposit boxes or vaults. This lock comprises a preferably rectangular casing 1, within which are mounted spaced disks 2 and 3. Disposed between these disks and eccentrically arranged with relation to the same is a tumbler or weight 4 having rigid connection with said disks by means of pins 5 or the like. The disks 2 and 3 are pivotally mounted upon a spindie 6 having reduced ends 7, which are rotatably mounted `within suitable openings formed through the sides of the casing 1. This spindle is provided withan aXial opening 8 for receiving a suitable key 9 carrying teeth 10. A ward 11 is disposed near the spindle 6, as shown in Fig. 1 and has rigid connection with the casing 1 by means of a pin 12, which is disposed within a curved slot 13 formed through the disk 3. This Ward is stationary `with relation to the casing 1 and is provided with suitable curved openings or slots 14. From the construction of the above referred to parts, it is obvious that the key 9 may be inserted within the spindle 6 and rotated so that its teeth 10 engage the tumbler 4 to oscillate the same. If a `key is employed having teeth notarranged in the same manner as the teeth on the key 9, such key cannot be rotated 4past the ward 11 and therefore could not aetuate the tumbler. It is to be understood that the form of key shownin Fig. 3
vmay be altered, provided that the ward 11 is correspondingly altered to cooperate therewith.
The casing 1 is provided near its corners with tracks or guides 15 between which are slidably mounted bolts 16. As shown in Fig. l, there are four of these bolts, which have their innerends pivotally connected with arms 17, as shown at 18, said arms having their inner ends disposed between and pivotally connected with the disks 2 and 3, as shown at 19. Certain of the bolts 16 are provided with cut-out portions 2O for receiving the free end of a pivoted tumbler or Weight 21. Each of the weights 21 has a ward 22 arranged near the same, as shown, having suitable openings 23 formed therethrough to receive teeth 24 of a key 25. These tumblers 21, together with their wards and keys, constitute locking mechanism for the bolts 16. I wish it understood that I may equip one or all of the bolts with the locking mechanism above referred to, and that the locking mechanism for each bolt may preferably employ a different key. It will thus be seen that if the four bolts 16 were provided with locking mechanisms, and each mechanism was unlocked by a different key, counting the key to actuate the tumbler 4, it would take five different keys to actuate the lock so that the door to which the same is secured could be opened.
In the form of lock as shown in Figs. 6 to 8, inclusive, a preferably rectangular casing 2G is provided, having tracks or guides 27, between which is slidably mounted a bolt 28. This bolt has pivotal connection, as
shown at 29, with an arm `30, the inner end of which is pivotally connected with a tumbler or weight 31, as shown at 32. This tumbler 3l is preferably triangular and is pivotally mounted upon a spindle 32a, having reduced cylindrical ends 33-which are rotatably mounted within suitable openings formed through the sides of the casing 26. The spindle 32EL is provided with .in axial opening 34 for receiving a key 35 having teeth 36. Arranged near and below the spindle 32a is a stationary ward 37 which is rigidly connected with the casing 26. This ward is provided with openings or grooves 38 to allow of the passage of the teeth 36, whereby said teeth may engage the tumbler 31 for oscillating the same. It is obvious that the ward 37 will prevent the use o'l' an improper key. The downward movement othe tumbler 31 and accordingly the outward throw of the bolt 28, may be regulated by the proper manipulation of a vscrew 39 tapped through the casing 26.
The lock shown in Fig. 9 is of the same construction as that shown in Figs. 6 and 7, except that the spindle 32a is dispensed with and the tumbler 31 is pivotally mounted upon a long spindle 40 which extends outwardly of the casing 26, as shown. ThisV spindle is rotatably mounted within openings formed through the casing 26. This spindle 40 is provided near its ends with a plurality of annular grooves 41 to receive a pawl 42 carried upon the tubular body portion ot a handle 43. The spindle 40 is provided with an axial opening 44 for receiving a key 45 having teeth 46. The handle 43 is also provided with a suitable opening for the reception of the key 45. The key 45 is adapted to fit snugly within the handle 43 and be held therein by a pin (not shown) which is to be inserted through the opening 47. The pawl 42 is held in its proper position by a spring 48 suitably secured to the tubular body portion of the handle 43. Although T have shown only one handle arranged upon the spindle 40, it is to be understood that a corresponding handle should be arranged upon each end of the same.V A ward 49 is disposed near the spindle 40 for coperationv with the key 45 to prevent the employment of an improper key.
Tn the operation of the lock shown in Figs. 1 to 5 inclusive, each of the bolts 16 are first released so that they are :tree to move, and then the disks 2 and 3 are rotated by the key 9. This rotation of the disk draws the bolts 16 wi-thin the casing 1. It is obvious that when the key 9 is released the tumbler 4 will return the bolts 16 to their outer positions.
Tt is thought that t-he operation of the lock disclosed in Figs. 6 to 10 inclusive is obvious, and such operation will not be stated.
T wish it understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes in the shape, size and arrangement of parts may be resorted to without departing 'from the spirit of my invention or the scope of the subjoined claims.
Having fully described my invention, I claim l. ln a lock of the character described, a casing, a spindle pivotally mounted within said casing, a tumbler pivotally mounted upon said spindle, a bolt having slidable engagement with the casing, means connecting said tumbler and bolt, said spindle being provided with an axial opening, and a key for insertion within said axial opening, having a portion extending beyond the periphery of the spindle to engage the tumbler for effecting a movement of the same.
