RADIATOR-CAP CONSTRUCTION.

Applicationfifiled December-12, 1927. Serial No. 239,575.

The invention relates to closures and more particularly to closures for the filler tubes of automobile radiators.

Many of the'advantages and much of the commercial value-and acceptability of the invention is attributed to the novel construction of the closure member and the cooperate ing adapter ring, these advantages being ob- 'tained particularly because of the simplicity of the construction'and the minimum number of parts employed. p This enables thel closure assembly to bel economically and quickly manufactured and easily installed and renders the same strong and durable. The invention therefore, depends Jfor some of its advantages, upon the speciic details of construction illustrated and about to be dey scribed.

Other objects and novel features of construction which contribute materially to the mechanical efficiency of the apparatus will be made more apparent as this description proceeds especially when considered in connection with the accompanying drawings, wherein Figure l is a perspective view oi a closure constructed in accordance with my invention' l Figure 2 is a side elevation partly in section showing the closure in closed position; and

Figure 3 is a sectional View taken on the line 3-3 of Figure 2. 4

Referring now to the drawing wherein like reference characters illustrate corresponding parts throughout the several views, the numeral 10 designates the filler neck of an automobile radiator and the numeral 11 indicates an adapter ring threadedly mounted Vupon the filler neck and permanently secured thereto by means of the set screw 12, which as shown, threadedly engages the adapter ring and abuts the filler neck. With this arrangement, the adapter ring may be accurately positionedrelative to the hood ridge construction (not shown). The adapter ring is also provided with an inwardly extending annular flange 13 spaced inwardly from the top surface 14 of the ring forming an L-shaped recess 15 adapted to receive a gasket 16 which may be of rubber, rubber composition or any suitable material. The adapter ring is further formed intermediate the inner face ot the flange 13l and threads 17 of the ring with an annular recess or groove 18 of a sui'- icient dimension to receive the member 19. As shown, this member is preferably formed of springmetal andin the present instance is shown as a piece of spring wire, the ends of which being spaced apart a substantial distance so as to yieldably force the arcuate portion 2O diametrically oppositek the spaced ends, against the side walls of the groove 18. Arranged within the ring adjacent the-forward edge thereof, is'an aperture 21'which as shown, extends downwardly from the top surface 14 OI" the ringV and intersects or opens into the groove 18 exposing a portion of the spring member 19.'. Hingedly mounted upon the ring diametrically opposite'the aperture 21 is a c losure member 22 having a depending projection 23 so positioned upon the latterl that in the closed position of the same. it will engage in the aperture 21 in substantialver'- tical alignment with the portion of the spring member 19 exposed by said aperture. As shown,.the 'lower endof the projection 23 is rounded oli' as indicated at 24 and is formed adjacent to the rounded portion aforesaid with a groove 25, the arrangement being that when the closure is swung to closed position the rounded portion 24 engages the arcuate portion 20 of the spring member 19 and forces the same inwardly until the acuate portion 20 is opposite the groove 25 at which time this portion will spring outwardly into the groove 25. To open the iiller tube an up ward force is exerted upon the closure member disengaging the arcuate portion 20 from the groove 25 and swinging. the closure to open position.

Thus from the foregoing, it will be noted that the herein described closure is relatively simple and economical in construction and one that may be operated with facility. V

While the invention has beenshown and described in connection with the filler tubes of automobile radiators andwhile the illus- .trative embodiment ot the invention is adapted for use upon such radiators, it should be noted that many of the objects and advantages of the present invention may be realized when the same is used in connection with various forms of containers and accordingly the inventioncontemplates such arrange ment.

What I claim as my invention is:

l. The combination With a filler tube of an automobile radiator and an adapter ring secured to said tube having an annular groove therein and having an aperture communicating with said groove, of a closure pivotally mounted u'pon said ring having a depending projection, and a spring member positioned Within the groove aforesaid and extending into said aperture, said member cooperating With the projection upon Vsaid closure to automatically latch the latter in'closed position.

2. The combination With a filler tube of an automobile radiator and an adapter ring secured to said tube having an annular groove therein and having an aperture communicating with said groove, of a closure pivotally mounted upon said ring, a spring member positioned Within'the groove aforesaid and eX- tending into saidvaperture, and a projection upon said closure adapted to register with Y saidl aperture when the closurev is swung to closed position, said projection having a recess in one face'thereof for receiving a portion of said spring member when ythe closure is in closed position.

3.. The combinationV Wth'a-container providing an opening thereinva'nd having a recess adjacent to said'opening, of a closure for said opening, means forlatching said closure inclosed position including a fieXibie member arranged Within` said opening and having a portion projecting into said recessl and means projecting from said closure and engageable. with the projecting'portion of said member when the closure is'in closed position upon the container.

l. The combination with 'a member having an opening therein and a recess posi-y tioned adjacent to said opening, of a flexible ring positioned Within said opening With a portion thereof projecting into said recess, and means carried by said closure adapted to move into said recess upon closing the clo- Asure and interlock With the projecting portion of said ring.

5. In combination a member having an opening therein with a groove in one wail thereof and having a recess positioned to one side of the said opening and communicating with said groove, a yieldable member disposed Within said groove and. having a portion projecting into said recess, and a closure for said opening having nieansoperable upon closing the closure to nieve-into said recess` and interlock with the projecting portion aforesaid of the yieldable member. V

6. The combination with a member having an opening therein and having a recess positioned at one side of said opening and communicating therewith, a flexible member positioned Within said opening and having a porclosing the closure to move into said recess and interlock With the projecting portion aforesaid of the ,fieXible member.

Intestimony whereof I affix my signature.`
