IMAIL-BAG' FASTENEB.

Application filed May 2,

This invention relates to mail bag fas- -teners.

An important object of the invention is tozprovide a device-of this character which may be cheaply andreadily produced and which. is so constructed as to afford guides preventing twisting of the cords forming theactual closure of the mail bag.

A further and more specific object or the,

invention is to: provide in combination with a zmail bag fastener including a cam a clamping element for clamping the cords of'the bag to prevent movement thereof with relation to the fastener, a mounting tor the clamping'm'echanism provided at op- -posite sides thereof with guides maintaining the cords separated to thereby prevent twisting of the cords under the "clamping wmechanism. It is well known that this twisting o1 the cords to :ottencauses improper action of the clamping' mechanism and furthercauses an undue "pressure 'to be placed upon the cords'which has a tendency to sever them.

:These and other objectsil attain by the construction shown in the accompanying drawings;wherein for the purpose of "illus tratlon is shown a preferred embodiment Lofimy invention and wherem 1-- Figure 1 isa perspective view of amail 4QI bagfastener constructed in accordance with my invention, showingthe'hasp in released position;

Referring now more part'cularly to the drawings, the numeral 10 Ldicates a'base plate provided upon its under surface at its longitudinal edges with reverted flanges 11 forming guides for edges of an address slip 12. Upon the upper surface or" the plate 10 at one end thereof is arranged a mounting its sides and at points spaced from its ends with upstanding aligned flanges i l the purpose of which will. presently appear. One end of the plate 13 is arranged to coincide with one end of the base plate 10, the plate 13 and the base plate 10 having aligned openings 1% through which extend rivets 15 formed upon the extremities of an arched guide plate 16, the rivets being headed upon the under surface of tle plate 10. The plate 13 has formed therein at this end and innnediately below the arch a further open-- ing 17 aligned with a similar opening tori er in the base plate and through. which extends a rivet 18 formed on the lower end of a partition plate 19 which extends from the upper surface oi: the plate to the under surface of the arch guide .16 and divides this arch to provide a pair of guide openings 20. It will be noted that the partition plate 19 and arch guide 16 serve, in addition to the function of providing the guide channels 20, t s a means tor-securing this end of the plate 13 to the base plate 1 Th numeral 21 designates a g use formed by providing a single piece oi metal and bending the ends or the metal baclrupon the central portion thereof to form loops the adjacent faces of which are spaced, and a base 23. The base 23 is preferably slightly longer than the loops 22 and this base abuts the opposite end of the plate 13 from the guide 16, the excess width of the base being arranged at the opposite end of the loops :22 from the plate 13 and being secured to the base plate by means or" rivets 24:. The base 23 has formed therein intermediate theadjacent tacesoftheloops. 22 an opening-.25

plate 13 which is provided at aligning with a similar opening formed in the base plate 10, and the adjacent end of the plate 13 has an opening 26 formed approximately centrally of the plate which likewise aligns with an opening formed in the base 10. The numeral 27 designates a staple in the form of a plate having a hasp receiving opening 28 and abutting with its lower end the adjacent ends of the plate 30 and base 23 of the guide 21, this plate being provided upon its lower edge with

integral extensions

29 and 30 engaging through the

openings

25 and 26 of the base and plate 13. respectively, and serving as rivets. It will be noted that the staple 27 serves'to anchor the rear end of the plate 13 and the forward end of the base23 of the guide 21 and to fasten these devices to the base plate 10, in addition to serving as the staple. This plate 27 by its engagement between the loops 22 of the guide is steadied thereby and prevent ed from sidewise movement in event of accidental engagement thereof. At the opposite end of the base plate 10 from that engaged by the plate 13 an archguide 31 is disposed, having at its ends rivets 32 directed through openings formed in the base plate and riveted upon the under surface thereof.

The flanges 14 of the plate 13, hereinbefore referred to, serve as mountings for the hasp 33, this hasp being formed with flanges 34 through which the pivots extend and being constructed at the pivot to provide a cam 36 which when the hasp is vertically arranged, as regards the base plate, provides suflicient clearance to permit the fastening ropes 37 with which the device is employed to slide readily therethrough. hen swung to a horizontal position where it parallels the base plate 10, the hasp abuts the upper surfaces of the

guides

21 and 31, being pro vided with a slot 38 through which the staple 27 extends sufliciently to permit the engagement of the usual fastening means in the opening 28 thereof; When in this position the cam 36 of the hasp abuts the ropes 37 very firmly forcing the same into engagement with the upper surface of the plate 13 and effectually prevents longitudinal move ment thereof.

It will be noted from the foregoing that the cam clamping element 36 is disposed intermediate a pair of

guides

16 and 21, each including means for maintaining the two strands of the rope separated, and that the staple 27 further assists in maintaining these ropes separated, accordingly, there is practicall 'no possibility of the ropes intermediate t ese guides becoming twisted so as to prevent their proper engagement by the cam 36. It Will furthermore'be obvious that the construction hereinbefore set forth is capable of some change andmodification without materially departing from the spirit of my invention and I accordingly do not limit myself to such specific'structure except as hereinafter claimed.
