ToZZ whom it may concern.'

Be it known that I, RICHARD Pnniss, a citizen of the United States, residing at Chicago, county of Cook, and State of 1 Illinois,` have invented a new and useful Improvement in Glosures, of which the tolinlets of.' radiators of motor vehicles and vwhich cannotizbe lost or easily entirely re- This invention relates to closures and more particularly pertains tocan improved closure "especially adapted for use on the moved by unauthorized persons.

Among thesmore important objects and` advantages otthis `invention are: the gen- 'Jerally loss-proofzand theft-prooi construction of thevclosure' or cap whereby its loss or `unauthorized `removal .entirely from the radiator or other' device to which it isk `applied is prevented, yet permitting the lmanipulationof the cap into open or closed positions jthe` embodiment of means radiator, and the generally improved struct'orlrmly locking the cap in closed posi tion; the provision-fot` a'cap of the character referred to which 1s ornamental as well as useful 5` the embodimentof the :tea- "tuies abovelpointed out and those which may bel pointed out Iorappearwlater in a compact and simple `unit structure which maybe appliedto any standard make of ture alording ardevice. ofl great durability yet simple 'and Icapableiof being Vmanufacturedatflow cost. y l

While thisinven'tionis particularly adapted foruse as aradiator cap or closure,` and Ator `the purpose of convenience slillustrated has such, it wilhbe understood that `itiinds a 'wide lieldofiutility 'for' other purposes. -40

Vby' I attainthe` ,foregoingand other objects i and advantages tobe1 pointecrcut' or appear `later is illustrated in the accompanying One embodiment of this'invention wheredrawing, in which; p i Fig; 11s an elevational viewof a device emf-.bodying theiinprovements ott-his invention.

rroflEge, Ylooking 'iin the direction indicated .the arrows, A Y Y "with ends 12-12 which impingeupon the iiange 8 andlock the base 5 on the radiator. Theinner ends ofthe screws 11 are provided with polygonal sockets 13-13, ttor reception ot-a suitable tool for driving -the screws home, a pair oli case-hardened rods, le-'14, extending vertically in the shank 7, back of the inner endsot the screws to prevent their accidental displacement. The base 5 is formed with an annular shoulder 15, which abuts the upper end of the iiange 8.

The base 5 is provided with a central "elliptical opening 16 to permit filling of the radiator and the cap 6 is provided for closing this opening. The upper surface' of the base f 5 is provided with an annular de- A pression 17,` which aords a` seatfor the cap i `6, theilatter having a coinplemental'ly formed `bottom face 18 adapted to engage the seat.

The cap is retained against complete removal from :theba'se 5 by a! pin in the `nature of a screw 19, forming a'perman'ent pivot ele ment, which enters at the bottom of the cap 1 and passes through a suitablev opening V20 in the base 5, the opening being in the nature of an arcuate slot,\best` shown in F1g.-2,

'i and thehead 2110i screw 19` engages beneath the slot 20, an arcuate recess 22 being substantially coeXtensive with the slotand ai- -o-rding a space Jfor the head 21 of' the screw. One: end of the slot is enlarged and counter Nsunkasat. 23 for receiving the head 'of the screwwhe'n the cap is in'open position,` as shown inFig. 5. It `will be observed that the slot 20eXtends through but a quarter of the` circumference of thecap.

Another arcuate slot 25 l is provided', i `-and its medial portionissubstantially diametrically opposite thatbtthe-slot 20, this slot "25 having I an enlarged opening` v26` at one f end, substantially Adiainetriea-l'ly opposite the countersunkfportion'25 'of thes1ot-.20- A screw pin127,y functioningl alr locking ele- `1 ment, aprojectsff from y rthe flower v face 1 ofi the cap 6 at a point diainetrically opposite the screw 19, and the said screw 27 is adapted to pass through the slot 25, the latter having an enlarged arcuate recess 28, coextensive therewith for accommodating the head 29 oi said screw 27. The opening 26 is of sufficient size to permit oi withdrawal of the head of the screw 27 therethrough, when the cap is in open position. The face of the recess 28 is provided with raised portions 30-30, which are located substantially at the medial portion of the recess 28, so that the head 29 of the screw 27 will ride thereunder when the cap 6 is turned on the base 5, as best shown in Fig. l. The cap 6 is provided with opposite laterally extending arms 3l-3l :tor imparting rotation to the cap, and the upper end of the cap is provided with an opening 32 for connection of a motormeter or some ornamental device, not shown.

In operation,`when in closed position, the cap 6 is arranged as best shown in Figs. 1, 3 and 4. Then it is desired to open the inlet to the radiator, the cap is rotated on the base 5 in a clockwise direction, as viewed in Fig. 2, the

screws

19 and 27 traveling in their respective slots until they abut the ends of the slots and are in engagem-ent with the enlarge-d portions 23 and 26, respectively. The cap can then be raised permitting the screw 27 to entirely clear its respective opening, whereupon the cap is swung to one side as indicated in Fig. 5. The steps outlined above are reversed when closing and locking the cap, the locking Jfunction being per formed by the head of the screw 27 riding over the raised portions 30-30. These portions 30-30 will prevent any ordinary vibration from rotating the cap while in closed position, thus serving to firmly retain the closure in the desired position, the arms 31-31 lying parallel to the top of the radiator.

While I have described my invention as embodied in a specific structural arrangement, it is obvious that minor changes in the details thereof may be made within the purview of the in-vention and scope of the claims.

I claim:

1l. In a device of the class described, in combination, a base, a closure and means for rotatably guiding the closure on said base, said means being axially movable of the base, When in a predetermined position, in

`which the closure is released from the base.

l2. In a device of the class described, in combination, a base, a closure, means for turning said closure about the axis of the base Without moving said closure axially of the base, and means for vlimiting the rotary movement, said limiting means being axially movable of the base.
