Patented May 19, 1931 UNITED STATES PATENT OFFICE KYLE E. STA-NT, OF CONNERSVILLE, INDIANA, ASBIGNOR TO THE STANT MACHINE COMPANY, OF CONNEBSVILLE, INDIANA, A CORPORATION OF INDIANA RADIATOR CAP Application filed October 25, 1928. Serial No. 315,031.

My invention relates to closures for receptacles and particularly to radiator caps for that purpose.

It is the object of my invention to provide a radiator cap that carries a non-rotatable, non-yielding, locking device, and a rotatable, flexible, sealing device, or a non-rotatable, flexible sealin device.

It is a furt or object to provide in such a combination a sealing device in which there is a combination of a relatively compressible sealing medium expansible in the presence of the locking parts of both yielding and sealing nature.

Referring to the drawlngs,

Figure 1 is a vertical section through the filler spout and radiator cap 1n locked position.

Figure 2 is a bottom plan v1ew thereof.

Figure 3 is a detailed plan v1ew of the locking cups carried on the radiator cap.

Figure 4 is a side elevation thereof.

Figure 5 is a detailed section through the method of attachment of the locking cup sealing member and yielding backing therefor, with the radiator cap.

Figure 6 is a bottom plan v1ew of the filler spout without the radiator cap.

Figure 7 is a section through the filler spout without the filler cap.

Figure 8 is a perspective of the 1ns1de of-the radiator cap without the yielding, sealing and locking members.

Referring to the drawings in detail, 1 1s a filler spout of a radiator or the spout of any receptacle. It is provided with an lnwardly extending, upward, marginal shoulder 2 which turns inwardly and downwardly as at 3.

This spout has depending from these spaced, inwardly depending shoulders 3 stop lugs 4. The lower edges of these depending members 3 are provided with cam surfaces 5. Engaging with these cam surfaces 5 and the stop lugs 4 are non-yielding, laterally extending, locking fingers 6 extending outwardly from the lower margin of a locking cup 7 which is provided with a square aperture 8 1n the center for mounting upon the square shoulder 9 of the radiator cap 10. This shoulder is mounted upon a depending finger 11 of the radiator cap.

The cup is retained in position either by having the end 12 of the depending finger 11 of the radiator cap 10 turned over and swaged in the nature of a rivet or a screw 13 may be employed which is threaded as at 14 in the'depending member 11 so that the degree of clamping the cup against the seating washer 15 and its yielding backing of brass 16 maybe adjusted.

The washer 15 and the brass disc 16 are rotatably mounted upon an annular shoulder 17 on the lower end of the depending member 11, so that they can freely rotate thereon if the adjustment of the clamping screw 13 permits. A lock washer 18 is provided in association with this screw for locking it in position.

The inner portion of the radiator cap 10 is provided with stop lugs 19 for engaging with the upper side of the yielding brass plate 16 if desired.

The engagement of lugs 19 with the top of plate 16 prevents said plate from becoming distorted beyond a predetermined plane or shape. Sufiicient space must be provided however between the plate and the lugs so that vertical movement of the plate will not be arrested to a degree that Would cause interference with complete rotation of the cap into locking engagement with the. spout.

While I prefer to make the sealing member of fiber which expands in the presence of hot water such as is found in radiators, yet any other form of sealing member may be employed; Likewise the brass disc 16 may be of any thin, yielding material. It is not necessary for the yielding member and the sealin member to both rotate, but it is found desira le.

I have found it very advantageous however to have a non-yieldin locking mechanism consisting of the locking fingers 6 and the filler spout cam lock with a separate yielding and sealing means for maintaming the parts, one in engagement with the other, because the use of heavy parts for locking permits of a very effective lock of long life, in combination with a more effective seal which can be made of thin, yielding and expansible material, thereby avoiding the disadvantage of some types of construction in which the lockin means is also yielding which defeats the e ficiency and durability of a positive look.

It will be understood that I desire to comprehend within my invention all the modifications necessary to adapt it to varying conditions and uses. 1

Having thus fully described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In a closure for receptacles, a filler spout having locking members, a radiator cap having a depending, non-rotatable, cooperating locking member and locking fingers thereon, a sealing means for sealing the cap to the filler spout, and yielding means backing the said sealing means in engagement with the filler spout and the radiator cap, said yielding means being rotatably mounted on the radiator cap, and portions ofsaid yielding means being spaced from the cap during rotation of said cap up to its locked position.

2. In a closure for receptacles, spout having locking members, a radiator cap having a depending, non-rotatable, cooperating locking member, a sealing meansfor sealing the cap to the filler spout, yielding means for holding the said sealing means in engagement with the filler spout and the radiator cap, said yielding means being r0- tatably mounted on the radiator cap, and portions of said yielding means being spaced from the cap during rotation of said cap up to its locked position.

3. In a closure for receptacles, a filler spout having locking members, a radiator cap having adepending, non-rotatable, cooperating locking member, a sealing means mounted on said radiator cap adapted for sealing the filler spout, yielding means for holding the said sealing means in engagement with the filler spout and the radiator cap, said last mentioned sealing and yieldin means being rotatably mounted on the ra iator cap, and portions of said yielding means being spaced from the cap during rotation of said cap up to its locked position, and stops on the filler spout for cooperating with the non-rotating locking means on the radiator cap for positioning the radiator cap when in locked position.

4. In a mechanism for a closure of a recepa fillertacle,-a filler spout, a non-yielding locking means on said filler spout, a cap, a non-yielding'locking means on said cap, and yielding means thereon for maintaining the nonyielding locking means in engagement and closing the opening in the filler spout, said yielding means being rotatable on the radiator cap and the locking means carried by the radiator cap non-rotatable thereon and portions of said yielding means being spaced irom the cap when said yielding means is in engagement with said spout during rotation of said cap up to its locked position.
