RADIATGR CAP FOR MOTOR VEHICLES.

. Application filed November 1, 1921. Serial. Ito. 511,977.

.trucks, tractors, aeroplanes, and the like.

A further object is to provide means for expeditiously opening and closing the fill-- ing opening, without the usual disizomfort and inconvenience experienced by the oper-- ator when the radiator stem is hot.

In carrying out the invention I provide a' cylindrical sleeve adapted to be threaded on the stem of a radiator surrounding the opening, said sleeve having a cap hinged to one side at the top which carries a cam adapted to engage a lug cast on the opposite side of the sleeve.

l construction designed to carry out the inventionwill be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is a side elevation of a radiator cap embodyingmy invention, P

Fig. 2 is a-plan view with a portion broken away showing the pivot pin of the link,

Fig. 3 is a vertical sectional view taken on the line 33 of Fig.2, and

Fig.4 is a detail showing a front elevation of the locking mechanism. 4

In the drawings the numeral 10 designates a cylindrical sleeve having an upwardly in- (lined shoulder 11 which merges into an annular flange 12 at the lower end of the sleeve. The \flange is internally screw threaded to engage the threads of a radiator stem 13, as is shown in Fig. 3. However, it is understood that the base of the sleeve mayassurne any practical shape, and that it may be externally threaded so as to engage internal threads of a radiatoi stem,

when it is sodesired. In order to provide a water-tight joint the base of the flange sleeve, a lug 16 is casted. The position of the lug is slightly lower than the ears. 15 with relation to the top of the latter. A cap 17 has a concave-convex crown 17' which merges into an annular flange 18. Cast on the flange is a depending log 19 having an aperture adapted to align with the apertures 15 of the ears 15 when the top of the sleeve is covered by the cap. The lug engages between the cars 15 and a pin 20 passed thru-the said apertures, whereby the cap is hin ed on the sleeve. An annular gasket 21 is integral with the crown and projects inwardly of the sleeve.

The gasket is closed so that a water-tight cover may be had.

Opposite the lug 19 a slot 22 is provided in the flange 18. The slot receives the upper reduced end of a link 23 which is pivoted on a pin 24-. A slot 25 adapted to receive the lug 16 is provided in the said link, and a cam 26 is pivoted in the lower portion of the slot on a pin 27-. The cam merges into a lever 28, the said cam being adapted to engage in a notch 29 in the underside of the lug l6.

It will be readily seen that the cap may be readily raised b pulling the lever upwardly and forwar ly so that the cam Wlll disengage the lug 16, as is shown in dotted lines in Fig. 1. When the cap is lowered the cam automatically rides over the lug 16 and the latter engages in the slot 25 of the link. By swinging the lever downwardly the cam is securely engaged in the notch 29 and against the outside of the sleeve. It will be seen that the lever is not swung to a perpendicular position, but is inclined outwardly. By this arrangement it is obvious that as the notch 29 wears the lever may be pushed inwardly, whereby the cam will still frictionally en age in said notch to hold the top of the sleeve.

.When it is desired a hole, as is shown in dotted lines in Fig. 2, may be provided ingasket 21 rictionally against the meter may be suitably mounted on the cap.

It is pointed out that a device constructed in accordance with my invention provides an eflicient means for covering the filling opening of the radiator of a motor vehicle. The cap may be quickly raised or lowered without inconvenience or discomfort to the operator, and when the cam is in engage ment in the notch 29, and with the outside of the sleeve the cap provides a water-tight cover for the sleeve.

Various changes in the'size and shape, as well as modifications, may be made without departing from the spiritof the invention.

What I claim, is:

I In a radiator filling cap structure, an ,longated upright sleeve having its lower 7 end arrangedifor securing to the filling collar offasradiator, a pair of hinge ears at thenpper edge of the sleeve, a cap having an annular seat in its underside, a gasket ring fitting in said seat and engaging on the upper edge of the sleeve, the cap havmg an annular flange overhanging the tending from the cam. and a radial lug evtending from the sleeve and engaged in the slot immediately over the cam, which is frictionally engaged with the underside of said lug when swung by the lever. the lever at all times being free from contact with the sleeve so as to provide finger spat-etherebetween.

In testimony whereof I aflix my signature.

- JOSEPH B. NORTHERN.
