Application December 27, 1948, Serial No. 67,290- 4A Claims. (C1. vaals) This invention pertains to an adjustable` l-ocking device and is particularly directed to a` keyoperated adjustable lock whereby two elements or articles may be inseparably connected. Even more particularly stated, the invention pertains to an adjustable. locking `device particularly adapted for use in closing and securely locking a dunnage bag such as a seamans bag, and providing means whereby the bag, after being thus locked or closed, can be lashed or secured to a stanchion, pipe, or other relatively immovable and fixed object so that the bag is locked and anchored. Similarly, objects such as motorcycles, bicycles and the like, may be lockedand anchored to axed object.
Locking devices capable of closing and' locking a bag or the like and simultaneously including means whereby the locked bag may be anchored to a fixed object are disclosed` in my `cci-'pending application Serial No. 609,289', now abandoned, and employ a flexible cablev provided with a plu rality of spaced, enlarged, stop elements, the flexible cable permitting locking means to beladjusted to any desired size or position. In' the device disclosed in my prior application, however, a padlock was employed in actuallylatching or holding the lock-ing means inv locked position. The present invention is directed to an improved form of device in which the flexible cableisan inseparable part of a cylinder lock, the device thereby being a complete, self-contained, adjustable unit of low weight, great strength, and remarkable flexibility in that it is capable fof. being employed under a great variety. of conditions.
Generally stated, the present invention relates to a rigid locking element capableof receiving a key for its actuation, said locking element having a flexible cable permanently connected thereto and including means for removably securing spaced portions of the cable4 thereto to thereby provide two separate loops rigidly connected to the, locking bar, said loops locking and -anchoring various devices to va stanchion, post or other object.
An object of the present invention,Y therefore, isl to disclose and provide asimple and efficient construction for an adjustable locking device.
A further object of the invention is to disclose and provide a relatively light weight, adjustable locking device employing a llexible cable.
A still further object of the device is to disclose and provide a key-operated adjustable lockingr` deviceadapted to form and releasablyhold two separately disposed Aloops of l cable, each loop resisting enlargement.
These and various` other objects of the invention will become apparent to those skilled in the art from the following description which will be amplied, in order to facilitate understanding, by reference to the appended drawings, infwhich:
Fig. 1 is a perspective view of the locking bar without its associated cable.
Fig. 2 is a side elevation indicating one illustrative position of a `cable with respect to the locking bar.
Fig. 3 is a plan view taken along the plane III-III of Fig. 2.
Fig. 4 is a plan view of a portion of the locking bar with the bolt in locked position.v
Fig. 5 is a side elevation of a portion of the locking bar of a slightly modified form.
Fig. 6 is a transverse sectionV taken along the plane lll-VI' of Fig. 5.
The rigid locking element or locking bar of the present invention preferably comprises a cylindrical housing Il] containing a Well known cylinder lock having a partially rotatable plug provided with a suitably shaped opening II adapted to receive a key. The partially rotatable plusr is suitably keyed into the housing to prevent longitudinal movement `of the plug Within the housing. The keyhole is preferably positioned in one end of the locking bar. `It is to be under'- stood that the locking bar neednot be cylindrical, as shown in the drawings,` but may be of polygonal cross section if desired.
The housing may be provided with an outstanding ear or lug I2 which may be ported so asl `to receive one end of a flexible cable I'4 as best shown in Fig. 2. The cable I4 may be soldered into the port of the ear I2 or it may be otherwise rmly and irremovably connected tothe ear. The cable I4 is preferably of appreciable length and provided with a plurality of spaced, enlarged, stop elements, such as the balls I5, I6, I1, etc. These various stop elements or balls may be swedged, pressed, brazed,` or otherwise attached to the` flexible cable I4.
The housing of the pear-shaped locking element is provided with a transversely extending groove in a side wallfof'saidA housing, the. bottoni portion of said groove being in communication with a longitudinally disposed slot so as to form la tongue from a portion of the side wall of the housing.
The transversely extending groove IS may be defined by the parallel walls 2U. and IZI, the cornersl or edges of the housing around` such groove being suitably rounded. Inasmuch as the housing Ill is cylindrical, the groove I9n may be.
said to have an open front and open opposing ends. The bottom portion of this groove I9 coinmunicates with a longitudinally extending slot 23 also having open ends. Preferably the slot 23 extends from the groove I9 in a direction away from the keyhole end II of the cylinder lock.
The groove I9 and slot 23 are suiiciently wide to receive a section of the cable. The bottom 24 of the groove I9 constitutes a face of a bolt head 25 rotatably positioned within the housing and selectively rotatable by actuation of the cylinder lock. The bolt head 25 is a part of the rotary plug of the cylindrical lock. The end of the bolt head, provided with the face 24 is of semi-circular cross-section whereas the rest of the rotary plug is rotatably mounted within the housing I as by means of an expansion ring 35 cooperating between a circular groove formed on the inner face of the housing I2 and a groove formed in the rotary plugj. The inner surfaces of the housing I are provided in the customary manner with a pair of opposed longitudinally extending grooves 35 into whichthe tumblers carried by the rotary plug extend when the device is in locked position and from which they are withdrawn by the key. The slot 23 extends longitudinally a vdistance suiicient to receive two adjacent sections of cable, as best illustrated in Figs. 3 and 4. It will be noted that when in unlocked position (Fig. 3) the face 24 oi the bolt head 25 extends 'between ends of groove I9 and is in alignment 'with the inner wall of slot 23; when the bolt head '25 is rotated 180 in a plane transverse to the .slot 23 into the position shown in Fig. 4, then the curved or cylindrical outer surface oi the bolt head acts as a plug for groove I8 and isolates slot 23 (which extends beyond the plane of rotation of the bolt head) irorntlie groove, thereby preventing cable in slot 223 from being withdrawn into groove I9.
The operation of the device can be readily understood from a consideration of an example. If, for instance, it is desired to close a sea-bag, the loose or free end of the cable (shown provided with a stop Il) is threaded through the grommet holes of a sea-bag indicated diagrammatically at 2l'. By pulling on the free end of the ilexible cable Id, the neck of the sea-bag may be constricted until the locking bar Ill is immediately adjacent the constricted neck of the seabag.
A section of the cable immediately adjacent the sea-bag is then inserted into the groove I9 and this section of the cable, indicated at I', is permitted to extend into the longitudinal slot 23. Since a number of stop elements, such as I5, Yand le, are carried by the cable, the tensioning of the devices around the neck of a sea-bag is carried out until one of these stops, such as the stop I5, is just beyond the locking bar IIJ. When the section Id slips into the slot 23, the stop element immediately adjacent said slot, such as the stop element I6, will bear against the outer surfaces of the locking bar Ill andhold the neck of the sea-bag in its constricted position. It will be noted that the expanding force of the cable tends to more rmly hold the section I of the cable within the slot 23.
if it is only desired to lock the sea-bag, the cylinder lock may be actuated by a suitable key, causing a partial 180 rotation of the bolt 25, the bolt in its locked position closing the groove I9, as illustrated in Fig. 4. If, however, it is desired to not only lock the sea-bag but also to anchor it to a stanchion or other fixed object, then the free end of the cable I4 is passed around a pipe, stanchion, or other xed object and the free end of the cable introduced through the groove I9 into the slot 23 so as to place the section I4" of the cable in the position indicated in Fig. 3. The cylinder lock is then returned with the appropriate key and as shown in Fig. 4, the bolt 25 will rmly lock both sections of cable in position, the free end of the cable being irremovably held by the locking bar by reason of the enlarged stop element II.
It is understood that in Fig. 2 the complete lower loop is not indicated in order to conserve space, but the broken ends of the cable are joined and carry additional stop elements, not shown.
Details of the cylinder lock are not shown since they form no part of the present invention. Cylinder locks capable of locking a bolt in two positions, one removed from the other, are well known in the art. It is to be noted that in the device illustrated in Figs. 2, 3 and 4 the stop elements, such asY It and Il, being larger than the groove I9 and slot 23, are held exteriorly of the locking bar ID. The modification illustrated in Figs. 5 and 6 shows a construction wherein the stop elements are enclosed by the housing. In this form of construction the groove I9 is suiciently wide to admit the stop elements l5 and I'I and the walls of the slot 23 are formed with recesses or indentations 28 and 29 adapted to receive the stop elements.
Although specic reference has been made to the utilization of the locking device with respect to a sea-bag, it is to be understood that the invention is not limited to this use but may be employed wherever it is deemed necessary or desirable to join two or more articles together, or to encircle and hold or lock a single object or article. For example, the device can be employed to good advantage in firmly connecting a` number of pieces of luggage so as to prevent their disposal. Numerous modications and changes can be made in the construction of the device and all changes and modications coming within the scope of the appended claims are embraced thereby.
