RADIATOR CAP Filed Oct. 4. 1928 use Patented Jan. 7, 1930 HENRY F. FISHER, OF LOS ANGELES, CALIFORNIA.

' RADIATOR, CAP

' Application filed October 4, 1928. Serial No. 310,303.

'10 conventional form of radiator which will have a hinged closure therein and a spring associated with the closure so that the clo-' sure may be forced downwardly within the cap but will be urged into itsnormal closed 15 position. v

lVith the foregoing and other objects in view whichwill be made manifest int-he following detailed description and specifically pointed out in the appended claims, reference 23 is had to the accompanying drawings, wherein Fig. 1 is a partial perspective of an automobile to which the improved radiator cap has been applied. 25 Fig. 2 is a top plan view of the improved radiator cap. 1 Fig. 3 is a vertical section taken through the radiator cap substantially on. the line 33 of Figure 2.

Fig. 4 is a bottom plan view of the radiator cap.

Fig. 5 illustrates a portion of the radiator and improved radiator cap in section, the 010- sure being held in open position during the administration of water to said radiator.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved radiator cap consists of a cap body having a reduced bottom portion 11 which is internally threaded as at 12 to receive the nipple 13 of an automobile radiator.

An aperture 14 is formed centrally of the top 15 of the caplO and a flange 16v is formed integral with the top 15 and extends into the aperture 14. A closureplate 17 is adapted to fit within the aperture 14 and is provided with a flange 18 adapted to co-operate with the flange 16 to limit the upper movement of the closure plate.

In the preferred form of construction, a pair of

lugs

19 and 20 areformed integral with the cap 10 upon the interior thereof. Upon the underside of the closure 17, an arm 21 is secured and in the preferred form of construction, the arm 21 is formed integral with the closure plate 17. This arm 21 is provided with a pair of lugs 22 and 23 adapted to be disposed between the

lugs

19 and 20 and to have a pintle 24 extend therethrough so that the closure plate 17 may be hingedly connected to the interior of the cap 10.

A, coil spring 25 is disposed about the pintle 24 between the lugs 22 and 23 and serves to bear against the arm 21 urging the closure plate 17 -into its uppermost position. "As clearly shown in Figure 3, the top surface of the closure plate 17 is flush with the top 15 of the cap 10. Also the under surface of the closure plate 17 is flush with the interior of 71) the cap 10. In the preferred form of construction, the top surface of the closure plate 17 and the peripheral surface of the cap 10 are both knurled or milled as shown in Figures 2 and 3.

'With reference to Figure 5, it is seen that to admit water to the radiator R it is merely necessary to thrust the spout of the faucet F against the closure which. will be forced downwardly while water is being admitted. Upon the withdrawal of the faucet F the closure will automatically assume its original normal position preventing water from being splashed out of the radiator, cap from. the radiator R. J p

The advantagesof this improved radiator cap are believed to. be self-evident. Itis no longer necessary to unscrew the cap which may be very hot or may be stuck upon the nipple 13, before water can be admitted to the radiator B. Other advantages of the device arise from the fact that the hinge connection between the closure and the cap 10 is hidden orprotected by the inwardly extending flange 15. In this manner on the insertion of the faucet F it will be readily understood that the faucet cannot strike or catch upon the closure plate 17 and damage the hinge or tear the hinge apart. Furthermore, as the closure plate swings inwardly, it can- 100 not. be struck so as to break the hinge as inthe case of closure caps which swmg upwardly. i

It is to be understood thatuvarious changes in the details of construction may be made without departing from the spirit or scope of the invention as defined by the appended claims.

I claim:

1. A radiator cap comprising abody hav ing a cylindrical portion and an inwardly extending top flange at the top thereof defining an aperture in the top of the cap, a closure for the aperture, said closure having anarm on the under side thereof which is pivotally connectedto the body so as to swing "downwardly, the pivotal connection being located beneath the top flangevbetween the edge of the aperture and the side of the body so as to be protected by the top flange, means for limiting the upward movement of the closure, and spring means for urging the closure into its uppermost position.

2. A radiator cap comprising a body having a cylindrical portion and an inwardly extending top flange at the top thereof defining an aperture in the top of the cap, a closure for the aperture, said closure having an arm on the under side thereof which isv pivotally connected to the body so as to swing downwardly, the pivotal connection being located beneath the top flange between the edge of the aperture and the side of the body so as to be protected by the top flange, means for limiting the upward movement of the clo sure, and spring means for urging the closure into its uppermost position, said closure being so constructed and so arranged that it will be flush with the top of the cap when in its-closed position.

' In testimony whereof I have signed my name to this specification. I
