BEE, OF CLEVELAND, OHIO, ASSIGNOR 1'0 I'HE EATON ELANUFACTURING COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO SEALING GASKET FOR NECK AND CLOSURE STRUCTURES Application filed February 1, 1929. Serial No. 336,:52.

This invention relates to improvements in gasoline tank. Said body member may be sealing gaskets for neck and closure strucan integral part of said receptacle or a septures, and more particularly, for neck and closure structures. of the bayonet-joint type. These structures are used, for example, with the radiators andtbe gasoline tanks of automobiles and eachincludes a tubular neck hav ing one end adapted to be secured to the radiator or gasoline tank around the ening therein and a closure adapted to be etachably connected to the other end of the neck, the sealing gasket being interposed between the closure and the neck.

The general object of the present invention is the provision of an improved sealing gasket for neck and closure structures of the character described, said gasket being of the usual annular form but instead of being a solid member is a, hollow member filled with com- 5 pressed air or the like, said gasket being of simple and inexpensive construction and having especially effective sealing portions for line engagement or contact with both the neck and the closure of the neck and closure struc- 95 ture.

Further ob'ects of the invention are in part obvious and in part will appear more in detail hereinafter.

In the accompanying drawin Fig. 1 is a an central vertical sectional view 0 one form of neck and closure structure having my improved sealing gasket, the view throu h the closure'being on the line 1--1, Fig. 2; ig. 2 is a bottom lan view of the closure of the structure; Fig. 3 is a top plan view of the neck of the structure; Fig. 4 is a central vertical sectional view of said neck on the line 4-4, 3; and Fig. 5 is a side view of the resent improved sealing gasket the gasket 10 eing partly in section and partly in elevation.

In the present embodiment of the invention, I have illustrated a neck and closure structure of the 'form shown in m Patent No. 1,593,847, of July 27, 1926, to w ich patent reference may be bad, if desired. The neck of the structure here illustrated includes a tubular body member 1 ada ted to be positioned about the opening 2 o a re- 60 ceptacle 3, such as an automobile radiator or arate member suitably secured thereto, the latter arrangement being here shown with said body member provided with a laterally or otherwise suitabl secured to the receptacle 3. Said body member is provided at its upper end with an inwardly extending transverse wall b which terminates in a depending flange 6. At two diametrically opposed points, portions of wall 5 and flange 6 are cut away to provide two opposed passageways 7 through which are adapted to be passed the locking fingers of the closure of the structure, as will later appear. The cutting away of portions ofsaid wall and said flange provides two depending flange portions 6 each of substantially semi-circular form and the lower edges of said flange portions are inclined to provide cam surfaces 8 along which ride the closure locking fingers in efiecting detachable connection of the closure to the neck. To limit rotary movement of said closure locking fingers up along said cam surfaces, each of the flange portions 6 is provided with a depending sto projection 9 adjacent the inner end or t e high point of its cam surface, and adjacent these stop projections each cam surface is provided with a dwell 10, in which dwells the closure locking fingers are adapted to seat when the closure is completely connected to the neck, all as will later appear.

The closure of the structure includes a body member having a dome-shaped top portion 15 and a depending cylindrical skirt portion 16 having a diameter slightly larger than that of the tubular neck body member 1, as clearly indicated in Fig. 1. Crimped or otherwise suitably secured to the closure body member at the junction of the top and skirt portions thereof is the edge portion 17 of a transverse disc 18 having a central cavity within which is crimped or otherwise suitably secured the substantially circular base portion 20 of the closure locking member. Said locking member also includes two diametrically opposed resilient locking fingers 21 extending downwardly and outwardly extending base flange 4 adapted to be welded from the base portion 20 thereof, as clearly shown in Fig. 1.

The closure is detachably connected to the neck by passing the locking fingers. 21 thereof downwardly through the neck passageways 7, the closure being then turned in a clockwise direction which causes the closure locking fingers to ride up the neck cam surfaces 8 until they reach the dwells 10 therein, further rotary movement in this direction of the closure locking fingers being prevented by the stop projections 9. To remove the closure it is only necessary to turn it in the reverse direction, whereupon the closure locking fingers leave the dwells 10, ride down the cam surfaces 8 until they reach the passageways 7, after which the closure can be readily lifted from the neck, all as will be readily understood.

For sealing purposes, a resilient gasket is usual y interposed between the closure and the neck of such a structure, said gasket lying between and engaging the top transverse wall 5 of the neck and the lower marginal surface of the transverse disc 18 of the closure. These gaskets are usually of cork, rubber or other material having the desired amount of resiliency but which are more or less rapidly deteriorated if subjected to certain liquids, such as the anti-freezing solutions put into automobile radiators in the winter.

The present improved sealing gasket is of extremely simple construction, with the necessary resiliency to make its sealing portions especially effective but made of metal or some other material which is not deteriorated if subjected to the anti-freezing solutions above mentioned, one material suitable for the purpose being spring brass.

Instead of being of the usual solid form, said gasket is hollow and is filled with compressed air or the like, which gives the gasket plenty of resiliency but without sacrifice of strength or of durability. The gasket is of the usu. l annular form in plan view but may be of different forms in cross section, so long as it possesses two edge or angular sealing portions for substantially line contact or engagement with both the closure and the neck.

In the present embodiment of the invention, the gasket is of diamond-shape in cross section and is made up of two members, similar in construction, an annular top member 25 of inverted substantially V-shaped cross section and an annular bottom member 26 of substantially V-shaped cross section. Said members have their inner and outer edge portions suitably interconnected by air-tight joints, and for the purpose of such connection, each of said members is provided at its edges with laterally extending annular flanges, the flanges of one member, such as the flanges 28 of the bottom member 26, being bent or crimped around the flanges 29 of the upper member, which flanges are preferably of less width, as shown.

The upper gasket member 25 is therefore provided with an annular ridge 31 of angular cross section for substantially line contact or engagement with the cross wall 18 of the closure and the lower gasket member 26 is provided with a similar annular ridge 32 of angular cross section for substantially line contact or engagement with the cross wall 5 of the neck, as indicated in Fig. 1. Of course, the position of the gasket might be reversed to make gasket member 26 the upper member and gasket member 25 the lower one. In this case, the gasket ridge 32 will engage the closure and gasket ridge 31 will engage the neck, as will be readily understood.

The annular chamber 35 of the asket is filled with compressed air or the like which gives the gasket suflicient resiliency to enable its sealing ridges 31, 32 to engage the closure and the neck with the desired pressure to effect tight seals, even though the closure locking lingers 21 are made quite resilient to enable the closure to be very easily connected to and disconnected from the neck.

I claim:

A gasket for sealing contact with opposed surfaces of cooperating neck and closure structures comprising, a permanently sealed fluid-tight hollow metal device of annular form having upper and lower annular sealing ridges of angular cross-section for substantially line contact with the opposed surfaces of said closure and neck structures, respectively, said sealing device including upper and lower members havin their inner and outer edges inter-connecte by air-tight 1o1nts.
