UNITED STATES PATENT OEEICE.

JOI-IN F. MAINS, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF flWVO-THIRDS TO BRUCE CARR AND HARVEIT M. LA FOLLETTE, OF SAME PLACE.

BAG-LOCK.

SPECIFICATION forming part of LettersPatent N0. 432,539, dated July 22, 1890. Application tiled December .16, 1889;y Serial No. 333,866. (No model.)

To all whom it may concern:

Be it known that I, JOHN FxlWIAINs, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Bag-Locks, ot which the following is a specification.

My invention relates to an improvement in the mail-bag lock for which Letters Patent No. 413,624c were granted to myself and others October 22, 1889. The lock shown in the above-mentioned patent consists, essent-ially, offa metallic casing, through which the free ends of the lacing-cord of a mail-bag are threaded, and a pair of dogs pivoted within the casing between the two ends of the cord, and having between them a sliding wedge which, when forced forward by a cam-shaped key, operates to force the dogs into engagement with the cord, thereby locking the cord and preventing its withdrawal, the dogs being normally out of engagement with the cord and the cord free to move longitudinally through the lock in either direction. v

rlhe objects ot myimprovement are t-o provide means for holding the dogs normally in engagement with the cord, so as to prevent the cord from moving in one direction, and to provide means contained entirely within the lock-case and presenting no projecting parts, whereby the pair of dogs pivoted wit-hin the case may be simultaneously released from the cord by the thumb or finger of the operator, all as hereinafter fully described.

The accompanying drawings illustrate my invention.

Figure l is a plan; Fig. 2, a plan of the interior, the top plate having been removed;

Fig. 3, a central longitudinal section; Fig. 4,.

a transverse section at a, Fig. l; and Fig. 5, a transverse section at h, Fig. l. Figs. (5, 7, 8, and 9 represent a modification of the same general plan as the preceding figures, being an exterior plan, al1-interior plan, a longitudinal section, and a transverse section, respectively. v

A and B-are plates of sheet-metal flanged at the edges ,to form a separable hollow casing, of which A is the bottom plate,'and B the top plate. The anged edges of plates A and B are cut away at lthe corners of the casing t0 form openings, through which the free ends of a cord C pass, the cord lying along and in contact with opposite inner sides of the casing. The bight D of the cord is to be nnderstoodto be laced through the open end of a mail o r other bag. (Not shown.)

E E are a pair ot dogs, which are pivoted at f to the bottom plate A. in such a manner that the outer edges of the free ends of the dogs engage the cord and clamp it against the upturned edges 7L 7L of the plate when the attempt is made to draw the cord through the casing in the direction 'ot the bight D, but allowing the cord to slide easily in the opposite direction. The free ends of dogs E are held normally in contact with the cord by a coiled spring j, whose opposite ends engage the ends of the dogs and force them outward.

K is a push-bar arranged to slide on the bottom plate of t-he casing and to engage at one end both ot the dogs on opposite sides-o' the pivot j'. The opposite end of bar K is turned upward, so as to project into an opening Z, formed in the top plate B. Plate B is provided on Yopposite sides of the opening l with the inwardly-turned flanges mm,which are formed, preferably, by turning down portions of the material of. the plate which are removed from the opening Z. The lower edges of the iianges m are cut away at fn, so as to rest upon the push-bar and hold it in place and to form shoulders o o, which limit the outward movement of the push-bar.

The plates A and B are held together by rivets p p and pivot f, passing through both plates.

In the modification shown in Figs. G to 9, inclusive, the dogs E, instead of being both mounted upon a single pivot, are mounted on separate pivots o r near opposite sides of the casing, thus increasing the leverage of the push-bar, the dogs being suitably extended and overlapping, as shown, so as to extend into the path of the push-bar. The push-bar t is also turned the other side up, so that its flat portion comes against the under side of the top plate, and the opening in the top plate is carried forward to the end of the plate.

In operation, the bight D of the cord C having been laced into a bag at its mouth, as before described, and the free ends passed vIOC " through the easing between the sides of the easing and the faces of dogs E E, as shown, the Cord may be drawn freely through the lock in the direction indicated by the arrow7 but cannot be drawn in the opposite direction, the dogs being held in Contact with the cord by the springj, and being, by reason of their relation to their pivot, clamped more tightly against the oord when drawn in that direction. When the cord is to be released, so as to permit the opening of v the bag, the operator places the end ot his thumb in the opening Z against the end ot' the push-bar, and, pushing thereon toward the dogs, the dogs are simultaneously swung inward, thus releasing the eord and permitting its withdrawal.

By the use of the push-bar arranged in the manner shown I am enabled to dispense with a key and to operate the dogs simultaneously wit-hout the use ot' any parts which project beyond the face of the loek-ease-a result of much value in this class of looks.

I claim as my invention- 1. In a bag-lock, thev combination of the easing, the pair ot' dogs pivoted Within the easing with their faces arranged to engage a eord passing along the opposite interior edges of the easing, the spring arranged to hold the dogs normally in engagement with the eord, and the push-bar arranged to slide longitudinally in the easing and having one end in engagement with both dogs and the other end accessible through the casing, whereby both dogs are operated simultaneously and the use of projecting parts is avoided, as set forth.

2. In a bag-lock, the combination of the easing formed of plate A and plate having the opening Z and inwardly-turned flanges m m, provided With shoulders 0, the dogs lil E, plvoted within the easing, and the push-bar K, adapted at one end to engage the dogs and held in place at the other end by the flanges Vm m, as set forth.

In a bagloek, the combination, with plate A, dogs E E, and push-bar K, of the top plate B, having opening Z and flanges fm, m, arranged to guide and limit the movement ot the push-bar, substantially set forth.
