FASTENING DEVICE FOR SEALED CONTAINERS.

Application 'filed March 15, 1926. Serial No. 94,887.

My invention relates to fastenings for sealed containers. and particularly to chests and the like in which clothing and articles subject to damage by moisture, dust or moths may be preserved against such liability.

My object is to provide a container that may be sealed and provided with fastening devices that shall preserve the sealed con dition in handling the container.

In the accompanying specification and claim and the drawings forming a part thereof, 1 have described and illustrated a preferred form of my invention.

In the drawings Fig. 1 is a perspective view of a container tfivhich my invention may be applied.

Fig. 2 is a plan showing the relation between the locking devices and the sealing member.

Fig. 3 is an enlarged sectional view on 33 Fig. 6, of a fragment showing one locking device in fastened position.

Fig. 4t is a similar fragmentary view, showing a fastening device in released position to permit opening of the cover.

Fig. 5 is a fragmentary view showing the type of hinge used to insure a perfect seal when container is fastened.

Fig. 6 is a fragmentary plan of one fastening device and its relation to the sealing member.

Fig. 7 shows a modified form ofmy fastening device. 7 F p In the drawings 10 is a chest like receptacle, provided with a cover, 11, hinged thereto at 12. Interposed between the cover 11 and the edges of the walls of the chest 10, is shown a band of sealing material. This is preferably an endless band 13,

socketed in a channel 1 1, formed in the edges of the wall of the chest 10, contiguous to the underside of the cover when in closed position, and may be of any material impervious to the particular element against which the contents of the container is to be sealed.

I do not confine myself to the particular form of the seal shown, and may use a seal of sheet material, or when required,'one of plastic nature.

Secured to, and extending through the cover 11, is a plurality of locking devices in which fastening bolts 15 are adapted to engage cooperating members 16, secured rigidly within the receptacle, for the pur;

' pose of clamping the sealing material between the cover and the edges of the chest walls to insure a positive seal. To provide for a uniform clamping action on the sealing material 13, I employ a hinge for connecting the cover and the receptacle, which permits the application of the clamping pressure without resistance of the hinge joints, and have illu'stratedone form of hinge that may be used in Fig. 5. in which one hinge member 18 is slotted at 19 and is engaged by a hinge pin 20 forming a part of the other hinge member 21. This provides a hinged connection between the receptacle and the cover which permits a limited relative movement of the hinge members, lineally, and a uniform pressure may thus be brought to bear on the sealing member when the fastening devices are operated to seal the container. The fastening device illustrated in Figs. 3 and 4, is constructed as follows :-rigidly'secured to, and extending through the cover 11 is a tubular holder 25, integral with which is the internally formed shelf 26, which functions as an abutment for the flange 27, integral'with the fastening bolt 15. This bolt is formed with a head 29,'adapted to be engaged by a key by means of which the fastening bolt may be rotated to engage with the cooperating member 16, for the purpose of securing the cover to the receptacle, and at the same time clamp the sealing member between the cover and the edges of the recep tacle.

The fastening bolt is shouldered at 30, and downwardly extended is a stem 28, provided with a threaded portion 31, which is adapted to engage a correspondingly threaded opening in the member 16, within and rigidly secured to the wall of the receptacle. Loosely mounted on the stem 28, and abutting the shoulder 30, is a collar 33, and secured within the holder near its lower end is another collar 34;, through which the threaded portion 31. extends. Loosely mounted on the stem 28, and one end bear ing on the collar 34, is a spring 35, which reacts on the collar 33, for the purpose of cansing the withdrawal of the fastening bolt,

axially when not engaged with the threaded member 16, the relative lengths of the shank and stem portions of the bolt 15 being such that it may bewithdrawn a suitable distance to permit the opening and closing of the cover, Without interference of parts; the

collar 31 engaging the under side of the shelf 26, and preventing further withdrawal of the fastening bolt, the spring operating to yieldingly support the bolt in this position.

I do not confine myself to the exact construction shown and may employ modified forms which fall within the scope of the claim, and such a modification is shown in Fig. 7, in which I. have shown a fastening bolt in which the polygonal head shown in Figs. 1, 8, 4, 6 adapted to be engaged by a socketed key, is omitted, and I employ a recess 40 formed in the bolt and adapted to be engaged by a correspondingshaped key. Also I have substituted for the threaded portion 31, a projection 31 from the stem 28, which is adapted to engage a cam shaped recess 42 formed in the member 16, which is channeled at 43 to permit the insertion and rotation of the stem 28 and the projection 31' therefrom. It will be evident that when the projection 31 engages the recess 42, and is partially rotated by the means described, that there will be a clamping action to produce the results required.

Having thus described my invention, I claim 2- In a container comprising a receptacle and a cover, fastening devices, each comprising a holder, rigidly secured to the cover; a clamping bolt therein, rotativelyand axially movable, and extending through the cover; a cooperating member rigidly secured within the receptacle; a projection formed within the holder and adapted to engage the clamping bolt for the purpose of limiting its axial movement; a collar rigidly secured within the holder; a spring,

bearing on the collar and reacting on the clamping bolt for the purpose ofwithdrawing it within the holder when disengaged from the cooperating element; and a key c
