Nov. 5, 1929. w. Y. HUTCHINS CLOSURE Filed Jan. 16, 1929 2 Sheets-Sheet Patented Nov. 5, 1929 WI LLIAM Y. HUTCHINS, OF KINGSPORT, TENNESSEE CLOSURE Application filed January 16, 1929. Serial No. 332,844.

This invention relates to closures and has particular reference to closures for openings designed to be closed in an air, gas and watertight manner, and in which the operation of sealing the opening may be easily, conveniently and quickly performed.

One object of the invention is to provide a closure for openings in life saving suits, aviators garments, gas bags ofballoons and other similar receptacles whereby the opening may be rapidly closed and held closed in a secure manner against leakage of air, Water or gases.

A further object ofthe invention is to provide fastening means which will hold the margins of the opening closed against relative opening movement in any direction and in which a novel construction of double closure fastener and interposed seal are employed to make the closed opening air, gas and water-tight.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which v Figure l is a front view of a life saving garment showing the application of the invention thereto, the closure being in open condition.

Figure 2 is a similar view showing the clo sure in closed condition.

Figure 3 is a front view of a portion of the garment on an enlarged scale and showing the closure partly closed and partly open.

F igure 4 is a view similar to Figure 3, omitting the runner and showing the outer closure flaps partly broken away to expose the sealing flaps.

Figures 5 and 6 are cross-sections through the closure flaps, sealing flaps and runner and showing, respectively, the arrangement of the flaps in open and closed conditions of the fastener.

Figure 7 is a perspective View of the runner.

Figure 8 is a view similar to Figure 6, showing a slight modification.

Figure 9 is a view similar to Flgure 7, showing another modification.

In the accompanying drawings, I have shown my invention as applied, for exemplilication, to one type of receptacle, to wit, the acket part of a union life saving suit for use on shipboard, or a combined flying and life saving suit for aviators, but it is to be understood that the invention may be applied to gas bags of balloons or other gas or liquid containers, and that, therefore, the word receptacle as used herein is designed to apply to any container or enclosing structure havmg an opening to be closed either against the entrance or the escape of water, air, gas, or other liquids or fluids.

Referring to the drawings, 1 designates a garment of the character described the jacket portion of which is provided with an open ing 2, the

marginal portions

3 and 4 of which are, in accordance with this invention, pro vided with pockets or sheaths 5 enclosing

sealing strips

6 and 7. These

strips

6 and 7 may be formed ofa soft compressible and expansible material, such as soft vulcanized rubber, and such strips may be vulcanized or cemented by indissoluble cement to the material ofthe garment 1.

Secured at or near their relatively outer edges to each

marginal edge

3 and 4 are a pair of

closing flaps

8 and 9, the inner portions of which are free and extend parallel with the inner and outer faces of the free portion of the marginal edge to which they are attached. To the tree portion of each

flap

8 and 9 are applied U-shaped

metallic cross cleats

10 and 11 arranged so as to lie transversely of each side and across the free v edge of the flap, the said cleats comprising stationary locking members the relatively outer edges of which provide abutment and guide shoulders 12 for eoaction with a movable fastening member or runner 13. As shown, the cleats 10 upon each flap 8 are arranged in alternation or in staggered order with respect to the cleats 11 upon the opposing flap 9, and the inner portions of the sets of cleats 10 project beyond the free edges of the flaps and engage within the spaces between the cleats of the opposed cleats 11, and vice versa, when the margins and 4 are drawn together to close the opening 2.

' basically considered, and to the extent of comprising a pair of closure flaps and a tapered runner, the flaps having abutments for engagement by the runner, is well known, but,

so far as I am aware,such closure fasteners have heretofore been of single fastener form, that is to say, a single runner has been provided for c'oaction with sets of abutments on one pair of opposing flaps only, and, in general, located only upon the outer faces of the single pair of flaps. My invention difiers from this prior type of fastener in the provision of at least two pairs of flaps 8-8, 99 on opposite (outer and inner) sides of the

margins

3 and 4, in connection with a double or twin runner, or other multiple form of runner, for coaction therewith. My invention is further distinguished from prior closures of this general character by the provision of the-sealing stripsfi and 7 for coaction with the flaps and the runner, as will now be described.

As shown,- therunner 13 is formed of two.

outer plates 14 and two relatively inner plates 15, each outer plate 14: and adjacent inner plate 15 forming a runner, such runners of the double or twin runner thus provided respectively cooperating. with the outer and inner pairs of

closure flaps

8 and 9. At the top all: the plates are connected by a bridge 16 carrying-a manipulating ring or member 17, and the plates are provided with inclined flanges 18 for. engagement with the shoulders 12 of the

cleats

10 and 11. By this construction it will be seen that the fiapson both sides of the runner, as well as both sides of each flap, while at the same time the inner pair of plates form guides engaging the sealing strips tion are guided accurately into engagement and the sets of engaging members hold the connected edges against relative movement in any direction. When, therefore, theopening is closed it will remain closed against all pressures short of tearing or breaking pressures, and the strength of the construction is such that it will withstand very great pressures and strains. 'It will be observed that the edges of the sealing strips pro'ect inwardly beyond the edges of the aps, as shown in Fig. 5, to such an extent that when the opening is closed the abutting edges of the strips will be held under compression, as shown in Fig. 6, thus sealing the joint against the passage of air, water, gas or other liquid orfiuid. As the flaps and strips are stayed in this position by theconnection of the mulsealing,

tiple sets of engaging members, no gapping can occur as long as the parts remain connected and intact.

' My invention will be found very desirable and advantageous for use in closing accessopenings where leakage of liquid or fluid is to be prevented for considerable periods, and a type of closure for this purpose is provided which may be operated simply and very rapidly for closing and opening actions.

It is to be understoodthat the number of flaps, the runner may be increased when it sired to increase the security of the fastening connection.

While I have shown in the present instance, in its basic form, a well-known type of quickclosing fastener which .may be employed, it is to be understood that the invention is'not limited to this particular" form of fastener,

the advantages of the invention.

As shown in Fig. 8 one of the sealing strips may be provided witha groove 19 to receive a tongue 19 on the edge of the other, and

as shown in Fig. 9 a manipulating hook or like member 17 a may be arranged at the front instead of at the top of the runner.

Having thus fully described my invention, I claim 1. A receptacle having an opening provided with sealing strips along its marginal edges, a pair'of closure flaps at each side of the opening and upon opposite sides of each strip, transverse engaging members on eac pair of closure flaps, and a-runner in guided engagement with the sealingstrips and in operative engagement with the flaps to draw the opposed strips and flaps together or to force them apart.

2. A receptacle having an opening provided with sealing strips of elastic material along its' marginal edges, a pair of closure flaps at each side of the opening and upon opposite sides of each sealin strip, transverse engaging members on eah pair of closure flaps, and a runner in guided engagement with the sealing strips and in operative engagement with the flaps to draw the opposed strips and flaps. together or to force them apart, the said sealing strips having their free edges arranged so as to be placed under compression'when the strips and flaps are drawn together.

3. A receptacle having an opening provided with sealing strips along its marginal edges, a pair of closure flaps at-each side of the opening and upon opposite sides of each sealing strip, each flap having at each side transverse engaging members to interengage between the corresponding members of the each flap for drawing the strips and flaps together or forcing them apart.

4. A receptacle having an opening provided with sealing strips of elastic material arranged so as to be placed under compression when the strips and flaps are drawn together, a pair of closure flaps'at each side of the opening and upon opposite sides of each sealing strip, each flap having at each side transverse engaging members to interengage between the corresponding members of the opposed flap, and a runner in guided enga ement with the sealing strips and engagea le with the engaging members on both sides of each flap for drawing the strips and flaps t0- gether or forcin them apart.

5. A receptacl e having an opening, twin engaging flaps at each side of the opening, transverse engaging members on the twin engaging flaps, sealing means adapted to be brought together upon the closure of the flaps, and a runner having twin operators to engage the flaps and draw the flaps together or force them apart. 4

In testimon whereof I aflix my signature.
