rIVhe present invention relates to caps'for automobile radiators; and its robject is to provlde improved means for securing such caps to the necks of the radiators ofauto-` mobiles.

This Vobject is attained by, andthe invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings,vin which e Figure 1 is a top plan view of a portion of a cap for an automobile radiator, shown partly in section taken on line 1-1 of Figure 2; Y n

Figure 2 is a side view of the same applied to aradiator and shown partly in section taken on line 2 2 of Figure 1;

Figure 3 is an axial sectional yview (enlarged) of a plug, taken on the same plane;

Figure 4 is a cross sectional view of this plug and of a portion of t-he body of the cap taken on line 4e4 of Figures 2 and 3; and

Figure 5 is an outer end View of the plug.

The radiator 1 of an automobile has an upwardly extending hollow neck 2 through which water is supplied to ill'the radiator. This neck is threaded at 3 (as .shown in Figure 2) and the hollow cylindrical body 4 i of the cap surrounding this neck is threaded thereon and carries a cover 5 for the radiator pivotally mounted at 6 on said body and carrying means 7 for supporting a ther-k otally mounted at 10 on the body 4 of the cap.

`In order to securely fasten the cap on the neck of the radiator and prevent its unauthorized removal therefrom, I provide a set screw 11 threaded in the inner portion 12 ofan openingthroughv the side wall of the body 4, the inner end` of this screw, when screwed down, engaging and somewhat upsetting the threads of the neck 2 in the mounted position of the capr on said neck; and in order to prevent tampering with and unscrewing this screw, I provide a plugl 13 which is inserted into the outer portion 14 of said opening and is held against removal therefrom by a bolt 15 slidable in the transverse orifice 16 in the plug. The end 17 of plug seen in Figure 2, is seated by its slid-A ing movement in a socket 18A in the body 4 portion of the opening. ToV insert the plug into said opening it is turned half-way around from its position seen in Figures 2 and 3, whereupon the bolt slides to a position wherein it does not project from the orifice 16. When the plug is inserted into the opening it is turned half-way around, whereupon the bolt slides to the position seen in Figures 2 and 3, so that its lower end 17 projects beyond the plug and is seated in the socket 18, thus preventing the plug from being withdrawn until all the parts are turned upside down, whereupon; the bolt slides so that its end 17 is withdrawn from the socket. Stops 20, 21 are provided for holding the bolt in the orice 16 of the plug in the bolts sliding movements, thus preventing the bolt from becoming lost when the plug is not inserted into its operative position. The stop 20 is made by punching in a small portion of the plug so that the same projects into the orificeV 16, as shown in Figure 3. The plug is desirably provided at its outer end with a radially extending flange 22, to facilitate its ready handling, which flange has a frangible portion 23 adjacent the body of the plug, such portion being thus frangible in order that the flange will be broken ofi' if an attempt be madeto force the plug out of the opening and the bolt willV remain'unbroken and seated in the socket.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular-embodiment thereof illustrated by 'the drawings or hereinbefore shown or -described.

I claim: f

V 1. In a cap for automobile radiators: a hollow cylindrical body surrounding the neck of the radiator, carrying a cover therefor, and provided with an opening through its sidewall having a lthreaded inner portion and an outer portion provided with a Vsocket in its side; a set screw threaded in said inner portion and engaging said neck to lock the capthereto; a plug slidably inserted into said outer portion and having a extending-from the lower side Iof saidouter transversely extending orice'; a bolt slidable in said oriice and into said socket, the

plug having stops to hold the bolt in said orifice in its sliding movements.

2. In a cap for automobile radiators: a hollow cylindrical body surrounding the neck of the radiator, carrying a cover therefor, and provided with an opening through its side wall having a threaded inner portion and an outer portion provided With a socket in its side; a set screw threaded in said l0 inner portion and engaging said neck to lock the cap thereto; aplug slidably inserted into said outer portion and having a. transversely extending orifice; a bolt slidable in said orifice and into said Socket, the pluor having at its outer end a radially exten ing {lange with a frangible portion adjacent the body of the plug.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 5th day of September, 1923.

JOHN W. SEALOCK.
