JOHN F. WHITE, 0F CHICAGO, ILLINOIS. ASSIGNOR T0 WHITE PRODUCTS CHICAGO, ILLINOIS, A C0 OFICE.
RPORATION 0F ILLINOIS.
RADIATOR-CAP LOCK.
Application led September 18, 1920. Serial No. 411,254.
To all whom t may concern.'
Be it known that I, JOHN F. WHITE, a citizen of the United States, residing at Chi-A cago, in the county of Cook and State of Illinois, have invented certain new and usev ful Improvements in a Radiator-Cap Lock,
of which the following is a specification.
This invention relates to radiator cap locks, that is to'say, to mechanism for securing an automobile radiator cap, on which a motor meter may be mounted, on the auto- .mobile radiator nipple in such a way as to prevent unauthorized removal thereof. It accomplishes thisl purpose without necessitating any modification of the radiator nipple and in a very simple and effective manner, by the construction illustrated in the accompanying drawing, in which` ig. 1`is a central vertical section through a radiator nipple and cap equipped with my invention;
Fig. 2 is a bottom view, the nipple being in section; and
Fig. 3 is a diametrical vertical section transversely of Fig. 1.
In these views, the numeral l designates the radiator nipple, 2 the body of the cap, 3 the arms thereof, and 4 the screw-threaded portion in the lower side of body 2, by which it is removably mounted on the nipple 1. circular opening in thetop of body 2 for the reception of the stem of a motor meter or ornament (not shown), and 6 a counterbore or recess about the opening 5, for the reception of the means (not shown) by which the meter is secured to the cap.
A cylindrical lock-casing 7, of well known construction, 'is' secured within the cap to one side of its 8, .and is provided with the slidablebolts or tumblers 9, adapted to be projected and retracted by the usual key, shown in dotted lines at 10 in Fig. 1,.insertable in the slots 1l. Numeral 12 designates a cam dog pivotally mounted on a pin 13, secured in the cap body 2 to one side of its center 'at 90 from the lock casing 7, as clearly appears in Fig.
center by a rivet connection adapted to frictionally engage the inside surface 15 of the radiator nipple l.
The device operates as follows:
After the cap has been screwed 'on the radiator nipple, the key is manipulated to project the bolts or tumblers 9 so that those arranged for cooperation with the dog encoMraNY, or
gage its operating arm and swing it on its pivot, which places the dog in the fullline position of Fig. 2, in which the nose 17 is pressed against the surface 15. Now any attempted rotation of the cap to the left to remove it from the radiator nipple will tend to rotate the dog on its pivot in such fashion astoeswing the major' axis of the cam arm toward the surface 15, thereby wedging the nose 17 still more forcibly against the surface 15o, and making it impossible to unscrew the cap. When itis desired to remove the' cap, thekey is inserted and operates to retract the bolt or tumblers 9, whereupon the cam line position in Fig. 2, in which the nose 17 is. free from the surface 15 and offers no resistance to the rotation of the cap.
Various modifications in the details and assemblage of the device may be made without departure from.' the spirit of the invention, as, for instance, the contour of the ca xn dog may be such as to require unlocking by means of the key when the cap is to be placed on the radiator, -although preferably the construction illustrated is employed wherein the cap can be turned freely, in a right handl or clockwise direction even when locked the cam only engaging the surface l5 effectively' when it is lattempted to be removed by rotation in a left hand or counter-clockwise direction.
Moreover, while I have illustrated and described `the invention as applied to the locking of a radiator cap in position, it w11l be evident that the same isapplicable in lOther changes will readily occur to the dog is free to swing into the dotted skilled miechanic as `within thescope of the invention as I claim:
1. A lock for radiator caps and thev llke, comprising a locking dog pivotally mounted within thecap and having a nose adapted to engage and bind againstthe inner surface of the radiator nipple, and a key-operated defined in the appended claims.
holt Within said cap movable into and ontI cap off-cooperation with said dog to control its position.
2. A lock for radiator caps and the like,
comprising a looking dog pivotally mounted Within the cap and having a nose adapted to engage and bind against the inner surface and a lock casing mounted in saidxcap and operable from of the radiator nipple,
outside by a key and comprising a slidable bolt movable into and out of cooperation with said dog and e'eotive to press the saine into operative relation to the nipple.
3. A lock for radiator caps and the like,
comprising a cam dog pivoted Within theoap and consisting of an operating arm and the radiator nippie,
nose adapted to engage and a lock casing protectively mounted Within the cap and havin ya sliding bolt-movable said arm to-press said into engagement wit nose against said nipple.
4r. A. lock' for radiator a key-operated lock the cap and having caps and the like., seribing Witnesses. comprising the combination with the cap of casing mounted Within a horizontally slidable bolt and a locking dog pivoted Within the.
neiaeea and having an operating arm lying in the "path of the holt and a earn nose adapted to @ramp against the innensnrface of the radiator nipple, whereby when said holt is projected said nose will be forced into locking engagement with said surface and the turning of the cap in a direction to remove the same will be prevented.
5. A. closure, comprising the combination with a tubular mounting, of a cap having screw engagement therewith to close the samal said cap having laterally-extended handles whereby it may he rotated on said mounting, a dog carried by the cap and adapted to bind against the mounting under pressure from said handles to prevent rotation of the cap, and a key-operated bolt movable into engagement with the dog to eeet its operative engagement with the mounting.
