Description:

The object of my invention is to provide a locking unit adapted for securely attaching various movable objects together, or for attaching parcels such as luggage &c to some fixed object for preventing moving of same, and for many other similar purposes.

Another object is to provide a flexible cable locking unit that may be readily adjusted and adapted to various size or shape objects, and where the cable may be locked in any desired position without any other external means.

A further object is to provide an adjustable cable lock that is simple in construction, easily and efficiently applied and operated, that can be folded into a small convenient pocket unit, and that can be manufactured at a very low cost.

These several objects are attained in the preferred form by the construction and arrangement of parts more fully hereinafter set forth. Similar parts on the drawing are marked by similar numerals or letters.

Fig. 1 illustrates my invention in its assembled form, showing the general arrangement of its various operating parts.

Fig. 2 is a sectional view through the cable, taken on the line 2-2 of the Fig. 1, showing an elevation of the locking unit casing and the cable channels formed therethrough.

Fig. 3 is an enlarged detail view of the casing and lock mechanism, with the cap plate removed, showing the general arrangement and position of the automatic lock operating elements and means for engaging the cable walls in any position.

I will now describe more fully the detail conSstruction of my device, referring to the drawing and the marks thereon.

The lock casing A is made of any suitable metal, either formed or cast, and of any desired shape or design, but preferably of a thin, recessed, disc Sbase I having a circular cap plate 2 fitted thereover and attached to the disc face by suitable rivets or screws 3. A cable anchor channel 4 is formed within the base 1, edgewise thereof, and receives the end of a flexible metal cable B seScurely mounted therein. The flexible cable B is securely attached within the recess 4 by rivets 5, or any other suitable means. An open cable channel 6 is formed through the opposite side of $he base section 1, also edgewise thereof, and preferably at an angle to the opposite anchor channel 4 as is illustrated in Figs. 1 and 3 of the drawing. The cable channel 6 is of a size to allow the free end of the cable B to pass freely therethrough which may be adjusted to any position , therein. The disc base recess a is extended to open into the cable, channel 6 by a receding wall section b, which provides internal contact with the cable unit as the same is adjusted through the lock casing. Within the base recess a is mounted an L-shaped cable locking cam 7, hingedly attached thereon by a pivot pin 8 fixedly mounted in the base recess bottom, at right angles thereto. The cable locking cam 1 is preferably formed with a concentric hinge bearing f, and with a semi-recessed corrugated outer end c, designed and positioned to contact and fit over the exposed cable wall within the receding recess b, and engage therewith whenever the free cable end is forced in the withdrawal direction within the open cable channel 6. The hinge bearing f is supported by an adjacent circular segment shoulder g, positioned to receive the cam thrust caused by the connecting cable load. The cam action will securely lock the cable B therein. To insure a more effective locking surface, the cable channel 6 is formed with a further recess d, positioned opposite the corrugated cam end c, allowing the cam 7 to slightly depress the cable therein when a pulling force is applied to the cable member. The locking cam 7 is also formed with a special operating arm e, positioned approximately at right angles thereto, and is contacted by an operating cam spring 9 mounted within the base recess a. The cam spring 9 is designed and stressed to force the cam 7 against the cable B at 80 all times, and with sufficient force to engage and lock the cable on any movement thereof tending to withdraw said cable from the channel 6. A special release key 10, designed to engage a guide pin I I, or similar guiding unit, fixedly mounted in the casing base recess a, is provided for contacting the cam operating arm e, for displacing the cam 1 against its restraining spring 9, for releasing the cable B when desired, and for allowing the removal of said cable from the base channel 6. The release key 10 may be so rotated to a position at right angles to the operating arm e, and lock the cam 7 in an open position within the casing unit, and allow free movement of the cable B in either direction. Any suitable type of cable may be used, depending upon the purpose and application to which the cable lock is to be applied.

The Fig. 3 illustrates one form of cable locking elements, although other types and kinds of cable locking units may be also substituted there- 0o for, and might operate equally as well.

It is to be understood that my device is subject to various modifications in both design and mechanical construction without departing from the spirit of my invention, and I claim not only the a5 structure herein illustrated and described, but any other form or modification thereof in either cable or locking unit, that is substantially a substitution of parts and units herein disclosed. Having fully described my cable lock, what I claim as my invention and desire to secure by Letters Patent is: 1. A cable lock comprising a flexible metal cable, a suitable thin metal lock casing fixedly at1tached to one cable end, said casing being formed with an open cable channel therethrough for receiving the free cable end therein, a cable locking cam formed with a central bearing hub and a side operating arm, pivotally mounted within said casing with the cam outer end positioned to engage the free cable end within the cable channel, said casing also being formed with a cylindrical bearing shoulder opposite the locking cam arm and concentric with the cam bearing hub and engagable therewith, a cam spring mounted in the casing positioned to engage the cam operating arm and force the outer cam end against the cable, and a release key mountable rotatably within said casing designed to engage the operating arm and release the cam from the cable walls.

2. A cable lock comprising a flexible metal cable, a thin disc metal lock casing fixedly attached to one cable end by suitable attaching means, said casing being formed with an open cable channel edgewise therethrough for receiving the free cable end therein, a toothed locking cam formed with a central bearing hub and a side operating arm, pivotally mounted within said casing with the outer cam end positioned to engage the free cable end within the cable channel, said casing also being formed with a cylindrical bearing shoulder positioned opposite the locking cam arm and concentric with the cam bearing hub and engagable therewith, also formed with a cable recess along its cable channel opposite the outer cam end, a cam spring mounted within the casing positioned to engage the cam operating arm and force said cam against the cable walls, and a key mountable rotatably within the casing designed to engage the cam operating arm and release the cam from the cable wall.
