Specification of Letters Patent.
Patented June 2411, 1916..
Application filed April 8, 1914. Serial No. 830,523.
To all whom it may concern:
Be it known that we, GEORGE W. HOOK and OSCAR C. HOOK, citizens of the United States, residing at Brooklandville, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Locks, of which the following is a specification.
The object of this invention is to provide a lock of the permutation type having a case provided with a recess on the face thereof with a door to cover the recess, the bolt being mounted to be normally held in its locked position, and means being provided to move the bolt from the locked position when the permutation disks have been brought to the proper setting in Which the notches or slots thereof are in registry.
A further. object is in the provision of a connection between the cover for the recess portion of the case, and the means by which the bolt is moved to the inoperative relation, so arranged that as the cover is given movement in a predetermined relation the means to move the bolt will become operative.
With other objects in view, which will be referred to, our invention consists in the peculiar combination and novel arrangement of parts, such as will be hereinaftermore fully described in connection with the accompanying drawing and more particularly pointed out in the appended claims.
In the drawingz-Figure 1 is a view in side elevation of a padlock showing our improvement applied thereto. F ig. 2 is a view similar to Fig. 1 with the case of the padlock in section to illustrate the interior arrangement of the parts. Fig. 3 is a vertical transverse sectional view on the line 33 of Fig. 2. Fig. 4 is a similar view on the line 44. Fig. 5 is a horizontal transverse sectional view on the line 55 of Fig. 2. Fig. 6 is a view in side elevation of a lock of the trunk or chest type showing our invention applied thereto. Fig. 7 is a view similar to Fig. 6 showing parts in section to more clearly illustrate the manner of applying our invent-ion to this form of lock. Fig. 8 is a horizontal transverse sectional view through the lock shown in Figs. 6 and 7. Fig. 9 is view in side elevation and in partial section to disclose an adaptation of our invention to a lock of the type used on a swinging door. Fig. 10 is a fragmentary detail view to better shown in Fig. 9.
Referring to the structure disclosed in Figs. 1 to 5 inclusive, the body 1 and the shackle 2 are of the form usually adapted to padlocks, the shackle being pivoted in the usual manner at 3 to the body and the body provided at the opposite side with an openlng 4 to which the latch end 5 of the shackle may be inserted.
A slide bolt 6 is mounted within the body 1 in a position that it may be brought into engagement with the slot 7 of the latch end of the shackle 2. The bolt 6 is mounted to have endwise sliding movement into and out of 1ts engagement with thelocked end of the shackle 2. A bolt lever 8 is pivoted at 9 Within the casing or body 1 of the lock and the bolt 6 is connected with one end of this bolt lever 8 to have sliding and pivotal movement by a pin 10 carried by the lever 8 passing through a slot 11 formed in the bolt 6. Springs 12 are secured to the pin 9 on which the bolt lever 8 is pivoted and at illustrate the parts their free ends bear against the rear end of the bolt 6 to'hold the bolt normally in a position shown in Fig. 2, the bolt lever 8 being at the same time moved around its pivot 9 by the engagement of the pin 10 with one end of the slot 11.
Adjacent the free end of the bolt lever 8 the permutation disks 13 and 14 are mounted to have turning movement and to have their axes of rotation in the direction of the transverse extent of the body 1 of the lock. The disk 18 is secured on the pin 15 which extends through one side of the body of the lock and on its outer end has an indicating or dial wheel 16 secured. The disk 14 is carried by a sleeve 17 mounted to turn on the pin 15 and on the outer end of this sleeve an indicating wheel 18 is secured to lie between the side of the body 1 of the lock and the indicating wheel 16 secured on the pin 15. By arranging the parts in this manner the permutation disks 13 and 14 can be revolved in either direction and may be revolved independently one of the other. The disks 13 and 14 are provided around their peripheries with a plurality of comparatively shallow transverse slots 19 and 20, respectively. The disk 13 has a slot 21 formed in its periphery of a greater depth than the slot 19, and disk 14 has a similar slot 22.
sov
The bolt lever 8 has on its free end an arm 23 which extends in the direction of the permutation disks 13 and 14 and comes into close proximity therewith when the parts are in the relation shown in Fig. 2 in which the bolt is in its locking position. A releasing arm 24 is mounted pivotally on a pin 25 within the casing to engage with the free end of the bolt lever 8 and this releas ing arm has a thumb piece 26 connected therewith to extend through an opening 27 formed through the body 1 of'the padlock so that it can be operated from the exte nor. 7
*The operation 'of the lock is as follows: When the padlock is closed or locked the partsoccupy the relative position disclosed in Fig.2, the bolt 6 is held inits locking position in the notch 7 by the springs 12 hearing against the-"rear'end thereof, the
boltlever is held at a position that the arm 23 is out of engagementwith' the disks 13 and 14 by reason of its connection with the bolt 6 and the releasing'arm 24 is held in the position shown by the engagement of the .bolt lever therewith. With the parts in the relation shown, the thumb piece 26 may be depressed thus swinging the releasing arm 24 around its pivot andv throwing the bolt lever around its pivot on the pin '9 toward the permutation disks 13 and 14, the arm 23 of the lever 8 will bebrought into engagement with these disks and may pass into the slots 19 and 20, however, this movement of thebolt lever and the consequent movement of the bolt 6 through its connection by the pin 10 is not sufliciently great to withdraw the .;bolt 6 from the notch 7 ofthe latch end 5 of the bolt of the padlock, and consequently the bolt is not released. By turn'ing'the dial wheels 16 and 18 sothat they indicate a predetermined point, the
slots 21 and 22 of the disks 13 and 14 may be brought into registry and into the path of the arm 23. With the parts in this relation pressure upon the thumb piece 26 will throw the releasing lever around its pivot against the'bolt lever 8 and will cause the arm '23 thereon to bev moved into the slots 21. and 22 which permit greater swinging imovement of this bolt lever about. the pin 9 and withdraw the'bolt (ifrom the slot 7 thus releasing. the shackle 2 from its locked position. r
When the turning force is released from the thumb piece 26 the springs 12 will again slidethebolt 6 to its outward position and the bolt lever and the releasing arm will be moved back to their normal positions, the disks 13 and 14 may then be turned from thepredetermined position to which they have been. moved and it is not now possible to" swing the'bolt .lever'to its full extent around the pivot pin 9, in fact, the boltwith' the parts in this relation cannot be moved to a point with its locking end beyond the extent of the opening 4 through which the latch end of the shackle 2 is passed. This protrusion of the bolt 6 within the opening 4 does not however, prevent the closing and locking of the shackle 2. WVhen this bolt is closed the latch end 5 engages against the end of the bolt 6. The endwise pressure thus exerted causes the bolt 6 to be moved back against the tension of the springs 12 and this movement with relation to the bolt lever is permitted by the pin carried thereon passing through the slot 11 of the bolt.
"Vith the form of lock shown in Figs. 6, 7 and 8, the case is made of a slightly different design, it being square or substantially so and adapted to be rabbeted into the upper edge of a trunk or chest. A catch 28, which in its form and application is substantially the same as the latch end 5 of the shackle 2 of the prior disclosure, is seis pivoted to the casing and to which the cover plate 31 is secured extends through the casing at a point corresponding with the location of the pin 25 in the disclosure in Fig.2 and this pin 32 has a releasing arm 34 secured thereon to perform the same function as the releasing arm 24 in the disclosure of the padlock. To release this look from its operative position the cover plate 31 is swung, as shown in Fig. 6, to uncover the recessed portion, the indicating wheels are then turned to a position that the slots in the permutation disks register and are in a relation to receive the arm on the bolt lever. The cover plate 31 is then given a further downward swinging movement which causes 'the'releasing arm 34 to bear against the bolt lever and withdraw the bolt from the catch 28.
In the disclosure in Figs. 9 and 10, the casing of the lock is substantially the same as in Figs. 6, 7 and 8, and in this connection is adapted to be connected by rabbeting or otherwise to one of the side edges of a swinging door. The bolt 35 has the end beveled as at 36 and the member with respect to which the door is to be secured carries the socket 37 in position to receive this beveled. end of the bolt 35. slight modification is that a hand wheel 40 is provided to turn the releasing arm to a position that'it withdraws the bolt from its operative position.
From the foregoing, it will be seen that Another we have provided a lock structure of the permutation type so designed that it may be adapted to any of the forms of lock now in common use and one which while very simply and cheaply manufactured is yet very efficient in operation.
Vhile we have herein shown and described only specific forms of our invention, it will be understood that slight changes might be made in the form and arrangement of the parts to suit the particular adaptation without departing from the spirit and scope of our invention, and hence we do not wish to be limited thereto eX- cept for such limitations as the claims may import. r
