PATENT IVAN H. STANCE, OF CONNERSVILLE, INDIANA.

LOOK FOR RADIATOR CAPS.

Application filed July 5,

Ton whom it may concern:

Be it known that I, IVAN H. STANT, a citizen of the United States, and a resident of Connersville, county of Fayette, and State of Indiana, have invented a certain new and useful Lock for Radiator Caps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like narts.

This invention pertains to a lock device for radiator caps and mountings therefor, such as heat indicating devices, emblems and the like, and more particularly to that type of lock which is attached to the underside of the cap or to the mounting extending therethrough and is insertable within the neck of the radiator, after which it is moved to locking position.

One feature of the invention resides in the means for permitting the lock to be screwed onto the cap or mounting when turned to one position and thereafter be incapable of being unscrewed therefrom while in the other or normal position of the cap when locked on the radiator.

The further feature of the invention resides in the means for maintaining the looking member in locking position under normal conditions, but permitting its movement toinoperative position while being inserted in the radiator, said means being capable of releasing the locking member by means of proper application of a key in event that it is necessary to remove the cap under unusual circumstances.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Fig. 1 is a central vertical section through a portion of the radiator, its neck, locking device, radiator cap and mounting with parts broken away. Fig. 2 is a view similar to Fig. 1, showing the looking device in side elevation and the cap unscrewed from the radiator for permitting the radiator to be filled. Fig. 3 is a section taken onthe line 3-3 of Fig. 1. I In the drawings there is shown a. radiator shell 10. The shell is provided with the usual neck 11 on which the radiator cap 12 is adapted to be screwed. Said radiator cap is provided with the mounting 13 which may be 11th? 1 9. 11 9. @11 ind a i g d 1924. Serial No. 724,499.

vice or ornamental mounting of any nature. Said mounting is secured to the cap by extending a screw threaded bolt projection 14 therethrough which is usually secured to the underside of the cap by a bolt.

In place of the usual bolt, a locking device or anchor is provided which forms the subject of this invention, the same being connected to the bolt 14 of the member 13 by screwing thereon the internally threaded member 15 which is rotatably held in an annular groove 16 of the shell 17 said member being secured permanently therein,

but capable of being freely rotated.

The shell 17 is provided in one side thereof with a longitudinally extending bore 18, in which a locking pin 19 is positioned so as to readily slide therein. The connecting member 15 is also provided with a complementary bore 20 adapted to register there with. By means of this arrangement, it will be readily observed that the member 1.5 may be freely rotated with respect to the shell 17 when turned in one position, and when turned in the other position the pin 19 will move by gravity to a position where a portion thereof will extend into the bore '1- so as to lock the connecting member and shell and prevent the rotation of the former with respect to the latter. This enables one to readily screw the connecting member 15 onto the threaded projection 14L when the cap and locking device are turned upside down, but when in normal position and the locking member is in engagement with the radiator shell for locking the cap thereon, the free rotation of the connecting member 15 will prevent the unscrewing thereof.

In order that the locking device may be unscrewed from the radiator cap when it is removed from the radiator after having been in use for a period of time, and in event the pin is rusted or corroded so as to stick within the bore, there is provided an opening 21. in the side of the shell (J()1l'l1]l\ll1l0t1l3lll, 1 with the bore 18 and a downwardly extending reduced bore 22 in aligmnent therewith. After the device is locked in position, a lead shot may be wedged and forced into the opening 21 so as to close the same and also the connmniication between the

bores

18 and 22. However, if the pin 19 becomes stuck in the bore, the lead shot may be readily melted out and a small wire extended through the reduced bore 22 for forcing the pin into locking engagement,

The shell 17 is connected with a clownwardly extending stem 23 by a ball and socket joint connection comprising the ball or head 24 connected with the stem 23 having a reduced neck portion 25, the socket comprising the lower portion of the shell which is reduced, and the inwardly extending annular flange portions 26. It will be noted that the reduced portion of the shell is provided with a plurality of ports 27 therein for freely permitting the heat from the radiator to pass into the shell for effecting a heat indicating device.

The stem 23 has the lower portion thereof hollow or bored out, and is provided with bifurcated ends 28 between which an anchor member 29 is pivotally secured by a rivet 30, the anchor member having laterally-extending arms on either side of the stem 23 so formed as to engage the underside of the radiator neck 11 and prevent the removal thereof when in horizontal position, the same being capable of insertion or removal when moved about the pivotal connection 30 to a more vertical position.

For locking the anchor member in a horizontal or locking position, the same is provided with an upwardly extending central portion having a substantially flat surface 31v adapted to be engaged by a locking pin 32 in such manner as to prevent its movement about the pivotal mounting 30, when said pin is held in engagement with said surface 31. The pin 32 which lies in the bore, is provided on its upper end with a tapered or angular surface 33 which may be engaged by a screw threaded plug 34 which is screwed into the side of the stem for the purpose of holding and locking the pin 32 against the surface 31 for preventing movement of the anchor member 29. I The plug 34: is provided with a hexagonal key-receiving recess 35 in its head for receiving a key 36.

After the locking device has been con nected with the radiator cap, as above described, the anchor member 29 is moved to an angular position to permit its insertion through the radiator neck, after which it is forced to a horizontal locking position by a suitable tool. The plug 34.- is then-screwed into place for locking the pin 32. For looking the anchor member 29 in substantially horizontal position, it is tightened in place by the wrench or tool 36, after which a lead shot may be forced into the-recess 35 for preventing engagement with the plug and .its removal from looking position. The locking device is so constructed that upon unscrewing the cap from the radiator, it maybe drawn upwardly until the locking member engages the bottom oft-he radiator ,neck, "which will permit the shell. and cap. to

turn partially overthe side of the neck by reason of the ball and socket joint so thatthe radiator may be filled with water. There is, therefore, no occasion to remove the device excepting for unusual circumstances, in which event, it may be partially withdrawn and heat applied to the lead shot so as to cause the melting of the same, whereby it will run out of the recess 35 and permit the wrench 36 to be engaged therein for unscrewing the locking plug 34. With the locking plug out of engagement with the pin 32, a suitable tool may be used to move the anchor member 29 into such position as to permit the removal of the device from the radiator.

The invention claimed is:
