Renewed December 22, 1932 11 Claims.
This invention relates to a cap for an automobile gastank and the like and to means for locking the same to prevent the theft of gas.
The principal objects of the invention are to provide an improved cap and means carried by the cap for supporting an ordinary locking device in position and to provide means entirely beneath the cap for supporting the various parts which are necessary to secure a locking device in position and make it inaccessible from the outside. The invention also involves improve ments over my prior Patent No. 1,722,615, patented July 30, 1929.
Other objects and advantages of the invention will appear hereinafter.

Fig. 15 is a plan of the same, Figs. 3, 5, 8, 10, 12 and 14 constituting sectional views which, together show six of the parts of this invention spread out and separated but otherwise in proper relation to each other;
Fig. 16 is a plan of the filling inlet shown in Fig. 1;
Fig. 17 is a sectional view on the line 17-47 of Fig. 16, and
Fig. 18 is an end elevation of the supporting ring forthe cap and the pivotal connection by which the cap is mounted on it.
The invention is shown as applied to a gas tank 7 having a cylindrical sheet metal filling inlet 8, as usual. This filling inlet as shown in Figs. 16 and 17, is of the usual construction having a convex annular flange 9 around the top and extending inwardly and provided with two slots or notches 10 located opposite each other for a well known purpose. The inner sides of the convex portion 9 are provided with cams 11 which serve about the same purpose in this case as usual, being adapted ordinarily to receive a pair of outwardly extending flanges on the outer locking spring and tighten the cap in place as it is turned, the cams, of course, being opposite. This device is substantially the wellknown bayonet attachment.
For. the purpose of securing the cap on this filling cylinder 8 a ring 12 is employed, screwthreaded internally from top to bottom. At the bottom is a ring 13 shown as screwed into the bottom of the ring 12 although it could be integral with it. These two rings are shown as being secured together by a set screw 14. The ring 13 bears on the surface of the cylinder 8.
The top of the ring 13 is beveled to receive a split clamping ring 15. This split ring is beveled at the top and bottom and fits the bevel surface of the ring 13 and is provided with a knurled inner face and is also provided with a circumferential internal groove 16. Above this ring is a nut 17, which is beveled at the bottom and screw-threaded into the ring 12. The ring 15 is split and contractibie but, of course, does not engage the screw-threads. The turning of the nut 17 inwardly will cause the two beveled surfaces of the ring 15 to be put under pressure between the beveled surfaces of the ring 13 and nut, 17 and thus force this split ring 15 inwardly about the outer surface of the inlet 8 and clamp the whole device thereto. This furnishes means for anchoring the parts above to the cylinder 8 and firmly securing to the cylinder 8 this supporting ring 12 which constitutes the support for the parts to be described. It will be noticed that the features just described are substantially the same as described in my above mentioned patent.
According to this invention the ring 12 is provided with a pair of ears 13 which are perforated and spaced apart. Into these perforations extend the ends 19 of a circular spring 20 preferably formed of round wire. These ends are bent downwardly and outwardly and constitute a pivot for this ring. This ring is sprung into the concave edge 21 of a lock casing 22 which constitutes what might be called the main part of the cap. This lock casing is in the form of a fiat circular plate having a cylindrical portion 23 extending upwardly from it and a generally cylindrical portion 24 extending downwardly. It is in the interior of this cylindrical portion that the lock is located. On the bottom of the fiat plate of the lock casing 22 is an annular boss 25 integral with the plate and constituting a bearing as will appear. The lock casing 22 also has a depending circular. flange 28 which projects downwardly around certain parts to be described and extends down substantially to the ring 12 so that it constitutes means for preventing the insertion of the fingers or tools to injure or loosen the parts.
Sprung over the convex outer edge of this look casing so as to turn with it is a strong sheet metal cap 26. This cap has a circular opening 27 in the center. In the lock casing 22 is located a lock 42. The keyhole of this look is at the top and is closed by a pivoted springpressed cap 43. This lock is shown as provided with a locking bolt 44. The locking bolt is adapted to be projected into an internal circumferential groove 60 to prevent the look from rising. This groove serves as a slot for receiving the lock bolt 44 and need not be circumferential but is made so to reduce the cost of construction. The lock is also provided with a guiding projection 46 fixed in position and moving in a vertical guide slot 47 through the cylinder 24 so that the lock itself is not capable of turning in the casing 22. When the locking bolt 44 is projected, the lock cannot be raised in the casing.
Held under the lock casing and resting on the convex surface 9 is located a leather gasket or the like 30 and on this is a spring casing 36 which supports a sheet metal outer lock spring 32. This spring is made of a piece of flat metal cut to an annular form with two opposite flanges 33 extending downwardly and these are bent out at the bottom to form two feet 34 projecting outwardly opposite each other in the same plane. These feet 34 are adapted to be moved down through the openings 10 and turned into contact with the cam surfaces 11 to hold the device in position. 'The boss 25 rests on the spring 32 and is rounded on the bottom to reduce the friction.
In assembling, these two feet 34 are passed down through two openings 35 in the spring casing 36 and this spring casing is fixed with respect to the outer lock spring 32 thereby. This spring casing is generally cylindrical with a fiat upper surface through which the openings 35 extend and the cylindrical portion is provided with opposite grooves 37 constituting a continuation of these openings 35 and ways for receiving the flanges 33 and preventing relative rotary motion between these two parts 32 and 36.
On the inside the spring casing 36 is provided with an internal circular set of teeth and notches 33. At the bottom a lock collar 39 having a continuous flat bottom and a continuous cylindrical side fits into the spring casing and extends up to the teeth 38.
The look collar 39 is permanently fixed to the bottom of the cylinder 24, as by pressing it on the cylinder, or in any other way. Its purpose is to prevent tampering with the interior when the cap is open. This collar has a slot 59 registering with the slot 47 into which the guide 46 enters.
The cap 26 and lock casing 22 are fixed together by spinning or binding the edge of the cap around the convex edge of the casing 22. The cylinder 23 supports the cap near the center and they are supported on the circular spring 20 so that they can be turned back, as one piece, about the pivots 19 and so that when unlocked they can be turned on a vertical axis. The parts 36 and 32, being fixedly connected together and the teeth 38 projecting into an annular space between the bottom of a shoulder on the cylinder 24 of the lock casing and the top of the collar 39, the cap 26 can be turned by hand on these parts 32 and 36. The element composed of the parts 32 and 36 is fixed to the cylinder 8 by means of the cams 11 and projections 34 when the cap is closed.
When the key is inserted and the bolt 44 withdrawn from the groove 60, a spring 52 resting on a ledge 53 moves up the lock cap 51 to which the lock 42 is fixed. The rise of the lock, of course, carries with it the guide 46 along the slot 47 and into a position between two of the teeth 38. A little turn of the cap usually is necessary to bring them into register with the guide 46. Now the cap is free to be turned by hand. The whole device can be swung about the pivots 19 as is indicated in dotted lines in Fig. 1.
When the key is inserted it pushes the lock 42 down in opposition to the spring 52 to permit release. Also, the lock cap 51 can be pushed down until the bolt 44 registers with the groove 60.
In this way the cap is held when on the inlet 8 and locked. However, when unlocked and closed the cap can be turned.
Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.
