MAIL-BAG FASTENING.

SPECIFICATION forming part of Letters Patent 1\l"o.` 254,772, dated `March 7, 1882. Application filed December 19, 1881. (No model.)

To Vall whom it 'may concern:

Be itknown that I, ABNER JOHNSTON, a citizen ot'theUnited States, residing atBainbridge, in the county of Chenango and State of New York, have invented certain new and useful Improvements in Mail-Bag Fastening, Indicator, and Lock 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to theannexed drawings, makingapart of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective view of my invention; Fig. 2, a front elevation, with the upperplate of the lock removed to show the interior construction, and the tongue ofthe hinged plates disconnected therefrom; and Fig. 3 is a cross-section taken on a line through one of the staples.

The present invention has relation to that class of mailbag fastenings in which are employed a series ot' metal plates provided with tongues and longitudinal slots andconnected to a flexible strap, the bag having studsor projections adapted to slide in the slots and staples for the reception of the tongues.

The objectof the invention is to im prove the construction of the above class of fastenings,

y as will be hereinafter described, and subsequently pointed out in the claim.

In the accompanying drawings, A represents the mailbag, of the usual construction, with the flap B to close over the mouth of the same. To the outer Vside of the frpnt of tbe bag is securely fastened a series of staples, a, which, when the flap B ofthe bagis closed, pass through elongated openingsinsaidtlap. Between these openings are plates b, secured to the upper side of the iiap B, and having guides c, which extend up through openings in a hinged metallic strap, (l, formed of sections hinged or ljointed together, the guides c also serving to retain the strap (l on the flap B of the bag and limit its sliding movement. Each jointed section of the strap C is formed with a tongue, D, which passes through the staples a, thereby fastening the ilap to the bag at intervals throughout its entire width. The hinged or jointed strap G has openings, through which pass the staples a, and the last one of the series of jointed sections ofthe strap has a shouldered tongue,

E, and a receptacle, d, for a card having the name of the place or station thereon.

The lock F,which is firmly and securely fastened to the flap B, is constructed as follows: Two claws, e, are pivoted to the under plate ot' the lock, which grasp the shouldered tongue E and hold it, a curved spring,f, keeping the jaws engaged with the shoulders on the tongue.

When it is desired to unlock the bag the claws e are made to disengage with the shouldered tongue E by the pivoted arin g, the outer ends thereof being brought against the claws and forcing them in an outward direction, this being accomplished by a suitable key constructed for the purpose.

The position of the claws and pivoted arin when in the position to withdraw the tongue E is fully shown in dotted lilies, Fig. 2, and the jointed strap is required to be moved but a short distance in order to disconnect the tongues D with the several staples, thereby` enabling the flap of the bag to be raised.

The bag is self-locking, and by sliding the strap O in a direction toward the lock, as the tongue E strikes the ends of the claws e, it will force them outward until the shoulders on the tongue are embraced by the claws through the action of the springf.

My improvement can be readilyY applied to airy ot' the ordinary mail-bags with comparatively little expense, and its practicabillity and easy operation in locking or unlocking the bag save much time and labor, as Well as avoiding the annoyance and trouble usually expert enced with the old or common st y le ot' bag.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a mail-bag fastening, thejointed strap C, having tongues D and the shouldered tongue E, in combination with the staples a. and lock F, consisting of the pivoted claws c, pivoted arm g, and spring f, substantially as and for the purpose specied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ABNER JOHNSTON. Witnesses:

FRANKLIN B. PHINNEY, GaAs. S. HYNDs.
