GOIBlD FASTENEB LOCK.

Specification pf Letters Patent.

PatentedJuly 22, 1919.

Applicationfiled June.17, 19 185, Serial No .,2 40,411.

T0 .alli'whomz't may concern 7 Be it known L that I, GEORGE. O. Burro-N, a, citizen of the United, States, nesiding at i v le. n he coun y. f Jiefier o nd State of, Kentucky have invented certain new and useful Improvements in Cord Fas-. tener Locks; and ,I do declare, thefollowing o b a f ll, dear, land ex c de cr ption. of the'invention, such as will, enable, others, sk lle li h a to. WhiCh Q ent r in m ke nd use he s me.

My invention has. reference broadly to, cord fasteners such, asthose, used on the draw strings or, cords. of na ail; sacks, and the. i c of th de i sto. prov de a tremely simple and'inexpensive, yet ahighly efficient and in every way desirable attach ment which will prevent loosening of the fastener and consequent opening ofthe mail sack until the destination. of the latter is reached and the lockis removed fby, the use ofakey.

With the foregping. object. in. view,

of the device hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which forms a part of this application and in which:

Figure 1 is a perspective view of the lock applied to a cord fastener;

Fig. 2 is a longitudinal section of the lock in use, showing the cord fastener in side elevation; l I

Fig. 3 is a vertical transverse section on the plane of the line 33 of Fig. 2; and

Fig. 4 is a perspective view of the locking dog and its carrying shaft.

In the drawings above briefly described, the character C designates the draw cord of a mail sack or the like, and F designates the well known type of fastener used for securing the cord in operative position, said fastener having the usual destination plate P, cord guides G and cord gripping devices G. All of these parts are of well known construction and are merely shown for the purpose of illustrating the manner in which the present invention is used.

The numeral 1 designates an elongated channel shaped casing preferably stamped from metal and closed at one end as seen at 2, while the other end of said casing is open to permit free endwise sliding thereof over the entire fastener F. The opposite sides 3 of the casing 1 are suitably stamped hasp 2 is released, however,

the 's ide G, thu

invention resides in the novel construction at their, free edges to provide themwith longitudinal inwardly, facing grooves 4 adapted to receive therein the usual edges of, the fastener base.

A dog 5 is mounted on a longitudinal roe]; shaft 6 which is suitably mounted in the casing l, saiddog beingadapted for recepi l etween tw f h auid' sG, w re y to prevent removalof. the casing until said dog is released. One end ofshaft 6 passes through the closed end Q of easing 1 andis bent lateraljly to form an arm 7 upon which one end of a: slotted hasp or arm 8 is pivotally mounted, the slot 9 of the part 8 being adapted to receive therein a staple. 10 carried by the end 2 of the casing. It. will thus be seen that when the'part 8 is locked in placeby the'application of a pad lock or thelilre 11 130 the staple 10,the dog 5. will be held in operative position, When the the shaft 6 may dog 5 from. the pe mitt a eadw se l ding ofthe entire device from the fastener. In the present showing, one side 3 of the easing 1 is provided with an opening 12 which receives the dog 5 When the latter is released,

be turned to disengage the but it is to be understood that in some instances, the casing 1 might be bulged o'utwardly to obtain the same result. I Also, the dog might be so located as to eliminate the necessity of either an opening 12 or a bulge such as suggested.

he device may be easily applied and locked upon the fastener and will serve to positively prevent release of the cord C while the mail sack is being transported from one place to another, and when the destination is reached, the device may be easily removed in the manner above set forth. Before sliding the device in place, the cord C is folded back along the top of the fastener F as seen in Fig. 2, thus holding said cord against slippage, particularly since it is more or less gripped between the top of easing 1 and the fastener F. Since probably the best results are obtained from the several details shown and described, they are preferably followed, but within the scope of the invention as claimed, numerous minor changes may well be made. Also, it is to be understood that the invention is applicable to numerous kinds of cord fasteners .or buckles and is not restricted to use upon fasggners employed in connection with ma l 53 0 .1

I claim: 1. A look for cord fasteners, comprising a channel shaped casing applicable to and removable from the fastener by longitudinal sliding, the side Walls of said casing having longitudinal guides to slide upon the edges of the fastener, and lock controlled means for normally preventing sliding of the casing from the fastener.

2. A look for cord fasteners comprising a casing applicable to and removable from the fastener by longitudinal sliding, and lock-controlled means projectible into the casing to engage the fastener and prevent sliding of said casing until retracted.

3. A look for cord fasteners comprising a casing applicable toand removable from the fastener by longitudinal sliding, a dog projectible into said casing to engage the fastener and hold the casing against such sliding until said dog is retracted, and lockcontrolled means for holding said dog in operative position.

4. A look for cord fasteners comprising a casing applicable to and removable from the fastener by longitudinal sliding, a dog projectible into said casing to engage the. fastener and hold the casing against such sliding until said dog is retracted, a rock shaft on which said dog is carried, an arm on said shaft for turning it as required, and means for locking said arm against movement.

5. A look for cord fasteners comprising a casing applicable to and removable from the fastener by longitudinal sliding, a dog projectible into said casing to engage the fastener and hold the casing against such sliding until said dog is retracted, a. rock shaft on which said dog is carried, an arm on said shaft for turning it as required, said arm being mounted for swinging l0ngitudinally of the shaft and having an opening, a staple carried by said casing and receivable in said opening, and a lock for passage through said staple. y a

6. A look for cord fasteners comprising a channel-shaped casing whose sides are pro vided with inwardly facing longitudinal grooves to receive the edges of the fastener, whereby to assist in retaining the casing on the fastener and to permit endwvise sliding therefrom, and lock-controlled meians for preventing such sliding until released.

In testimony whereof I have hereunto set my hand.

GEORGE o. BURTON.
