I 4 Claims.

This invention relates to closure devices for gasoline tanks, radiators, and other forms of containers and, more particularly, to improvements therein-whereby the closure. may be locked in position.

. It is one of the objects of the invention to provide a locking device for use in connection-with .the commercial types. of. closures wherein the closure is held in position by securing means.

A further object of the invention isto provide a locking closure embodying the ordinary :cap and an ornamental; cover therefor, in which the cover is freely rotatable with respect when the closure is locked.

J A further. object of the invention is to provide a. locking closure embodying the ordinary cap and an. ornamental coverith'erefor, and in which the locking mechanism is adapted to secure the coveragainst rotation relative to the cap so. as to permit the closuretobe used as an ordinary nonlocking closure ortoi-permit the cover to be freely rotated relative to the cap when the latter is locked in position. v

- Other objects of the invention and the features of noveltywill. be apparent from the following description taken inconnection with the accompanying. drawings, of which Figurel is a planview of a closure device embodying one of the preferred forms of my invention;, Fig. 2 is a transverse section thereof on the line 2,2'of Fig. 1; w I Fig; 3 is a transverse section on the line 33'of Fig. 1;

T Fig. 4. is a detail section on the line A -'4 of V Fig. 3;. I

Fig; 5 is a view similarrto Fig. 4 but showing a slightly modified construction; l

Fig. 6 is a plan view, similar to Fig, 1, of another preferred form of my invention;

, Fig. 7 is a transverse section on the line 1-1 of Fig. 6; l i v Fig. 8 is a transverse section on the line 88 of Fig. 6; and

Fig. 9 .is a detail section on the "line 9'9 of neck such as is used on a gasoline tank or radiator of an automobile. This neck is provided with an internal flange ll having the usual openings l2 and the depending cams l3, the latter cooperating.with-the'fingers 'l-l on the cap to clamp the to the 'cap' filler neck opening. The locking fingers are secured against the bottom wall of the shell I5 by rivets l9.

A lock barrel is arranged on the upper side of the bottom wall of the shell l5 and is provided with a threaded extension 2| which extends "through the bottom wall, and a nut 22 and lock washer 23 are employed torigidly secure the barrel 2i tothe shell. The barrel20 has a laterally projecting flange 24 and the inner wall 25 of the cover, for the cap, isloosely arranged between this flange 24-and the flange ll, of the fshell, so as to be rotatable with respect to the cap. The wall 25 has ad'ownwardly extending flange 26 atits inner periphery which surrounds {the barrel 2!]. l V

The cylinder 27, of the lock proper,is' rotatably arranged in the barrel 20 and provided with the usual tumblers-28 which are adapted to engage with the slots 29 in the barrel to holdthe cylinder against rotation relative to the barrel. A sliding bolt 3B is arranged in a slot 3| at the upper end oithebarrel Ziland is provided with a lip 32 with which a flnger33, on the cylinder 21, cooperatesto move the bolt to'the left, from its position in Fig. 3. A spring 34, carried bythe barrel 26, engages with the lip 32, asbest shown in Fig. 4, and is adapted to move the-boltj30 to theright in Fig. 4. I 1 3 A'plate 35 is arranged on the upperend of the barrel 20 and provided with a'boss 36, at its inner periphery, which engages with a collar 3'l, on

the'cylinder 21, to hold the shown in'Figs. 2 and 3. v p

The coverof the closure comprises, in addition to the inner wall 25, an outer wall 38 which may be suitably shaped for purposes of ornamentation. As illustrated, the outer wall 38 has a depending peripheral flange 39 which fits over and is secured to a peripheral flange on the inner wall latter in the'posi'tion 25. -The central portion of the outer wall 38 fits upon the plate 35 and has a central opening 4| which "surrounds the boss 36. I

The inner wall 25 of the cover is provided with a series of stamped up lugs 42 which are arranged in spaced relation about the, flange 240i the. barrel 20 and the end portion 43 of the bolt 30 is adapted to enter the spaces .be-

tween the lugs 42 and thereby hold the cover,

against rotation relative to the cap. When the cover is so held, the cap and cover may berotated as a'unit to move the fingers l4 over the cams l3 to secure the cap in position .on. the neck or'to disengage the fingers H fromflthe flange II and permit 1 the removal of the cap from the neck. A key 44, when inserted inthe cylinder 21, withdraws the tumblers 28 from the slots 29 soas to permit rotation of the cylinder relative to the barrel '20. When the cylinder is rotated in one direction the finger 33 thereon struction is that the breakage of one of the engages with the lip 32 onthe bolt 30 and withdraws the bolt to the position shown in Fig. 4. When the bolt is in this position it cannot en-' gage with the lugs 42 and therefore the cover will be freely rotatable with respect to the cap and the cover cannot be used as the 'means for rotating the cap so as to permit its removal from the neck. Withdrawal of the key 44 when the bolt 30 is inthe position shown inFig. 4, permits the tumblers 28 to engage with the slots 29 and thus lock the cylinder 21.

When it is desired to remove the cap, the key 44 is inserted in the cylinder 21 and the latter rotated a half turn to move the finger .33 to the position shown in Fig. 3. This permits the spring 34 to move the bolt 30 toward the right and into. one of, the spaces, between the lugs 42. If the end 43 happens to engage with one of the lugs .2,:a slight rotation of the cover will eflect disengagement and permit the end 43 to enter the space between the lugs. Thecover is thus locked to; the-cap and the latter may be turned the. cover as; desired to either remove the cap from. the filler neck or to apply it thereto. By withdrawing the key 44, under these circumstances, the cylinder 21 will be again locked to the barrel 20' and the closure device maybe applied ,to and removed from the neck like anordi nary .n n oe c pthe modification illustrated in Fig. 5, aplurality of coil springs 45 are used'for movingthe -.b l ;t3,3 ll instead of the single leaf spri ng 34 shown in Fig. 4. The advantage of, this con- .springs would; not seriously affect the operation of the lock,

. Referring now to the; form. of the invention illustrated in'Figs. 6 to 9, inclusive, the construction is, generally similarto that above describedbutthe locking bolt 50 is positively moved inboth directions by the finger on the cylinder 52. The finger 5| cooperates with the lips -53.,on-the opposite ends of thebolt.

54, in which the bolt 50 slides, has alateral ex.-

L tension '55 along one side of the bolt 50,and in thisyextensionthere is arranged aspring detent which cooperates with notches 51 and 58in the edge of the, bolt 50 to hold the bolt in its locking or retracted positions. It-will'also be noted-that the lugs, 5 9, which are stamped up .f rorn-. the inner wall 60 0f the cover, are V.-shaped,

as will be, seen in i 6, and the end of the bolt 50 is pointed, as will be seen from Fig. 9, so that; when,;the ,bolt 50 engages with oneof the lugs 59, the partswill slide on one another to permit the bolt to enter into a space between two: of the lugs 59.

In other respects, 7 7 two constructions: are substantially. the [same and function substantially in the same manner. The, construction illustrated in Figs. 6 to 9 has the advantage that the art" that changesi may be made in the details which have been illustrated and described without departing fromthe spirit ofthe invention, as defined in the appended claims.

The slot Having thus described my invention, I claim: 1. In closure devices, the combination of a member having an opening, a cap for closing said opening, said cap and saidmember having cooperating parts whereby the cap is adapted to be secured to said member by a rotary movement, a

.cover rotatably mounted on said cap, a lock barrel secured to said cap, a lock cylinder rotatably mountedin said barrel and having key actuated means for securing the barrel and cylinder against relative rotation, a bolt slidably mounted on said barrel, said cover having a circular series of V- shaped lugsadapted to be engaged by said bolt to secure the cover against rotation relative to the cap, and means on said cylinder for actuating cylinder rotatably arranged in said barrel, a bolt carried byv said barrel, means on said cover be- .said cap. comprising inner and outer walls which aresecured together, said inner wall having its inner peripheral portion loosely held between said cap and said flange so as to permit. thecover to be freely rotated relative to the cap, a lockcylinder rotatably arranged in said barrel, abolt carried by said barrel, spaced lugs stamped from the material of said inner wall and arranged radially outward from said fiangeiso. as to be en-' gaged by said bolt and thereby lock said cover against rotation relative to said cap,'and means on said cylinder for actuating said bolt.
