This invention relates to radiator caps. It is an object oi my invention to provide a radiator cap with a hinged sealing cap, which is locked in close engagement with the filler spout by means of a relatively movable ring lock member.

It is an object of this invention to provide a radiator cap in which the arts are thus rotated in relation to each 0t or for the purpose of locking the cap in closed relation with the part to which the cap is attached. The

radiator sealing cap may be rotated in regard to the ring, or the rin may be made' to rotate in regard to the sealmg cap. In the present instance, however, it is shown that the ring is rotated regard to the sealing.

it is also an object of this invention, in connection with a device of this type, to makea '20 radiator cap in which-the parts are few and so related that when the cap is in locked position the water is securely prevented from escaping.

For the purpose of illustration there is exdrawing a which is used only by way of illustration. Referring to the drawings: Figure 1 is a horizontal section on the 7 line 11 of Figure 4, showing the parts in unlocked position.

Figure 2 is a similar view showing the 'parts in locked position.

Figure 3-is a plan view of the stationary 5 collar. v V Figure 4 is a section on the line 4-4 of Figure 1. 4 Figure 5 is a section on the line 5-5 of Figure 2.. r

Figure 6 is a side elevation of the stationary v collar. Figure 7 is a partial sectional view of the locking ring.

This device is composed essentially of four parts, including a filler spout to which it is attached. The filler spout is indicated by the nunferal 1. The, numeral 2 is used to designate a stationary collar, while 3 is a sealing cap and 4 is the locking ring. These constitute the four parts of this device.

The parts 1 and 2 are held in interlocking relation with each other by means of threads 5. The stationary collar is screw threaded on the upper end of the stationary spout'and forms the entrance to the stationary spout.

On diametrically opposite sides of the sta- V tionary oollar are two vertical grooves 6, which end in two circumferentially arranged slots 7. Extending around the outer circumference of the stationary collar and just below the slots 7 is a groove 8, in which is located a snap rin which engages a corresponding groove ound in the locking ring. This snap ring is for the purpose of holding the locking mug in proper position on the stationary collar for rotation for engagement with the lugs on the cover. a

On the upper surface of the stationary collar is a circumferential groove 9 which re- 'ceives and carries thereina gasket 10. This gasket is to be engaged by the diaphragm from one edge of the stationary collar are two spaced ear members 11. These members receive between them. the corresponding members on the cover to form a hinged connection between the two. j

p The part of the stationary collar from which the ears 11 project is somewhat enlarged by means ofan outwardly projecting flange 11. The lug on the cover adapted to fit between the spaced ears 11 is indicated by the numeral 12. On the cover, about ninety degrees from the lug 12, are two diametrica ly oppositely disposed outwardly turned hooks 13, forming grooves 14, which receive suitable projections on the locking ring to lock the cover in close sealing en- Extending inwardly from the center of the cover is a projection 15 wliich is ada ted to carry and support a diaphragm mem er 16. This diaphragm is in 'close,engagement with thev projection 15 and is adapted, when the snap ring first to contract and then to expand back again into the groove 18 in the locking ring, leaving about one-half of the snap ring in groove 18 and about one-half in grove 8,

thereby holding the stationary collar and the lockingering together in non-movable, vertical relation to each other but in such a way that the locking ring can easily rotate in regard to the collar.

The lower part of the locking ring is restricted, as indicated by the numeral 17, so that this part is made to have a diameter practically the same as that of the outer diameter of thestationary spout, while the diameter 19 of the upper part is similar to the outer diameter of the stationary collar. Instead of the foregoing snap ring, any suitable equivalents therefor might be used.

On the extreme upper part of the ring there extends inwardly therefrom two diametrically opposed projections 20. When the cover is brought down into engagement with the stationary collar the outwardly turned hooks 13 enter the slots 7 but in that part of the slot away from the vertical groove 6, so that when the cover is pressed down and the locking ring rotated the projections 20 will come into engagement 'with the grooves 14 in the outwardly turned hooks 13 to securely lock the cover in sealing engagement with the stationary collar.

While the parts here shown call for a rotatable locking ring, yet the ring may be stationary and the other parts rotatable. The essential feature is that the parts are I movable in relation to each other regardless of which one of them is stationary. The interengaging parts on the stationary collar and the locking ring may be so'constructed that a rotation of'one in relation to the other tends to firmly close the cover upon the stationary collar and compress the diaphragm upon the gasket in the stationary collar.

Thenumeral 21 is used to designate the knurled part of the ring 4 that is to be gripped by the hand in operating this ring for the purpose of securely bringing the cover in engagement with the collar.

Having thus fully described my invention,

what I claim is new and desire to secure by Letters Patent, is:

1. In a radiator cap, in combination with a filler spout, a collar on said spout, a cover engaging said collar to close said spout, and means adapted to engage the collar and the cover to securely close the spout, said means being freely rotatable without affecting the relation of the spout and the cover. I

2. In a radiator cap, in combination with 'a filler spout, a collar on said spout, a cover pivoted to said collar and adapted to close said spout, and ring means adapted to engage the collar and cover to securely close the spout, said ring being freely rotatable without affecting the pivotal relation of the cover.

3. In a radiator cap, in combination with a filler spout, a collar on said spout, said col lar having vertical slots therein, a cover having circumferentially grooved studs thereon, said studs adapted to fit in said slots, and means movable in said slots to engage the grooves in said studs to hold the cover in close engagement with the collar.

4. In a radiator cap, in combination with a filler spout, a collar on said s out, said collar having oppositely dispose grooves and slots thereon, a cover having oppositely disposed circumferentially grooved studs thereon, said studs being adapted to fit in said slots, and means engaging said collar and having parts adapted to move in said grooves, and slots on said collar to engage the grooves in said studs to lock the cover to the collar to close the spou 5. In a radiator ca a collar having a groove therein, a cap or said collar, a locking ring surrounding said collar adapted to engage said cap and lock it on the collar, said locking ring having a groove facing the firstnamed grooves, and means'in said grooves to hold the locking ring on said collar.

6. In a radiator cap, a collar having a groove therein, a cap for said collar, a locking ring surrounding said collar adapted to engage said cap and lock it on the collar, said locking ring having a groove facing the firstnamed grooves, and a snap ring in said grooves to hold the locking ring on the collar.

7 In a radiator cap, an annular collar having a groove in the periphery thereof, a cap adapted to fit over said annular collar, a

locking ring surrounding said collar adapted to engage said cap and lock it on the collar,

said locking ring having a groove facing the first-named groove, and means in said grooves to hold the locking ring on the collar.

8. In a radiator cap, an annular collar having a groove in the periphery thereof, a cap adapted to fit over said annular collar, a locking ring surrounding said collar adapted to engage said cap and lock it on the collar, said locking ring having a groove facing the firstnamed groove, and a snap ring in said grooves to hold the locking ring on the collar.

In testimony whereof, I aflix my signature.
