Letters Patent No. 91,075, dated Juno 8, 1869.

IMPROVEMENT IN MAILLBAG-S.

The Schedulev referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that we, FRED. C. Bons'r and PHILAN- DER WONSEY, both of Spencerport, in the county of Monroe, and State of New York, have invented a certain new and useful Improvement in Mail-Bags; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this speciication, 'in which- Y Figure l represents a perspective view Figure 2, a cross-seetion'of' the top of the bag; and

Figure 3, a view in perspective of the springs removed fromthe mouth of the bag.

Like letters of reference indicate corresponding parts in all the figures.

Our invention consists in combunng'with the mouth of the bag an arrangement of springs, for the purpose of holding said mouth open while the bag is being filled.

In the drawings, A indicates the mail-bag, which may be of'the usual form.

In the month of this bag are sewed, -or otherwise secured, two light flat springs a a, so bent as to be of elliptic or oval form, and hinged together at the ends, as shown at b b, so as to have a free joint action.

To an overlapping flap, B, of the bag, is also sewed, or otherwise attached, another spring, c, of similar form to the others, and hinged or jointed to one of them by means of hinges d d.v

With these springs is connected an ordinary hook and eye, f g, so that when the bag is closed it maybe securedby lock and key in the usual way.

The novelty in this invention consists in the combination, with the mouth of the bag, of the jointed. springs a a c.

rlhe moment the hook and eye are disengaged.

the springs a a, by their expansion, throw the monthv of the bag open, and the spring c throws-the Hap open, thus expanding and opening the mouth, and retaining it in that position for filling without further attention.

Much difficulty has been heretofore experienced from the tlaecidity and yieldingness ofthe mouth; which made it necessary, in filling, to take hold of the mouth to open it every time a parcel was inserted.

To accomplish the `:result above described, it will be noticed that the springs are of peculiar construction, being bent of elliptical form and hinged together, and the flap-spring turning at right angles to the others. The`e1lipsis gives the proper opening, while `hinged together as'described, when combined with the mouth of bag A, in the manner and for the purpose specified.

` In witness whereof, we have hereunto signed our names, in the presence of two subscribing witnesses.

FRED.v C. BORST. PHILANDER WAONSEY.
