Application filed November 10, 1922. Serial No. 600,128. I

To all whom it may concern body 'is provided and this locking body snugly fits within the filling member of the I tel.

- tained within the tank from being withsition.

tank and thereby closes the same and eifectively excludes dust and other foreign mat- A further object is to provide a locking device wherein simple means is provided to hold the combined locking member and closure in position when within the filling member and in accordance with this invention the cap may be applied to the filling member after the removal of the key without interference by the lock.

A further object is to provide a filling member 'for automobile tanks having a grating which prevents the gasoline condrawn by means of a siphon.

A further object is to provide a locking means for automobile tanks which is of highly simplified construction, durable in use and cheap to manufacture. 4

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawing forming a part of this application'a'nd in which like numerals are employed to designate like parts throughout the same,

sectional view socket 14 will receive the lockin the improved lock and grate by means of which gasoline cannot be Withdrawn from the tank by a siphon. v

, In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 desig- Iiates a tank especially adapted for the reception of gasoline and having a tubular filling member 6 by means of which gasoline may be introduced into the tank.

However, any proper liquid may be in-- troduced into the tank 5 though in this case the tank is carried by the automobile and in most cases carries gasoline.

As illustrated in Figures 1 and 2 the tubular filling member 6 snugly receives a cylindrical plug or closure 8 the upper or rear end of which is formed with an annular flange 9 which flatly contacts with the rear end of the fillin member and thereby limits movement of t e plug or closure into In addition to this, the interior of the filling member 6 is provided interemediate its ends with an inwardly directed stop lug 12 which is received within a socket 14 in the lower portion of the cylindrical plug 8. It will be seen that the lug 12 when received within the socket 14 not only limits the downward movement of the plug 8 but also holds the plug against rotation when in po- The cylindrical plug 8 is provided with a longitudinally extendlng opening 20 which rotatably receives a lock casing 21 having a key receiving opening extending out through its rear end whereby a key 24 may be conveniently'inserted into the lock.

p, The locking disk 26 is arranged in advance of the plug 8 and is formed with a radial locking lug 28 which may be moved into a locking'notch 30 in the inner wall of the filling member.

It will be seen with reference to Figures 2 and 4 that the radial locking lug 28 may be positioned centrally of the plug 8 and in that case the plug may be conveniently removed and the lock is rotated by means of the key 24 so as to' move the locking lug 28 into the arcuate locking r tch 30, whereplug 8 is inserted into the casing so that the lugs 12 whereby the plug is held against ownward I movement and against rotation. By thus filling member 6 is holding the plu 8 against'rotationthe-lock ing disk 26 an the locking lug 28 carried thereby are positioned properly with rela-- tion to the locking notch 30 and it is not necessary to manually turn the plug after it is inserted into the casin Attention is directed to t e fact that the plug 8, the lock casing 21; the disk 26 and the locking lug 28 are all arranged within the filling member 6 so that tampering with these parts is absolutely prevented; The

lug 12 which is a stop member efi'ectivelycooperates with the'radial locking lug 28 in preventing theplug 8 from being forced downwardly through the filling member 6.

In carrylng out the invention the lower portion of the filling member 6 is provided with a grating 37 which prevents siphons from being introduced into the tank by an unauthorized person. I

It will be seen that the rear portion of the provided with external threads 40 with which the threads of the filler cab) may be engaged.

It wi be seen that the filler cap can be conveniently applied to the member 6 whenthe lock and the plug 8 are in position and these parts do not in any way interfere withthe application of the cap. Furthermore the parts are completely cap so that dust is efiectively exclude and concealed by the the lockis concealed from view.

Having thus described the invention,

what is claimed is V The combination with a. tubular filling member having its intermediate portion formed with an arcuate locking notch gradv I of the tubular member being formed with an internal inwardly directed stop element, I

said plu being formed with a' socket openhrough one end and the side there- 1 7 ing out t of to snugly receive said stop element, said stop element constituting a means to hold the plug against rotation, and a locking ciyl'linder extending longitudinally through t e plug and having its forward. ortion formed with a'disk, the peri hery 0 which is provided with a radial 10c ed to be received insaid notch.
