The invention relates to animprovement in locks for securing the sparetire of an automobile against unauthorized removal." It

consists of a lock, a connected chain, and a locking head at the freeend ofthe chain, which by reason of its peculiar construction is adapted to be engaged by the lock,'which locking head cannot beremoved or withdrawn from looking position, until after the lock' 1 has been operated by a. key pp ia The lock comprises a" casing providedwith a sliding U-shapedshackle, permanently 'se-' cured in the lock casing, yet having a move-1 ment sufiicient-to providea clearance between V the shackleand the lockcasing for the entry of a T-shaped locking head,th'e' said heaid being permanently attached to a 1 chain, the other end'of which is connected permanently with the lock, so that the parts forming my improved safety device'cannot become separated. hen the shackle is moved in a. re-

verse direction, after the locking head has been entered therein, the locking head cannot be withdrawn from the shackle until released by the key to the lock. f

The detailsgor" construction will now be described,- and the novelty of the invention will be pointed out in the appendedclaims.

tuted of plates 17 and 18, with ashortinter In the drawings,the numeral 10 indicates v i a lock easing and'numeral 11 the shackle thereof, the latter: being formed from a'rod bent into U-shape to provide parallel legs or posts 12 and 13,:which are passed through;

- the lock casing-1O andare engageable bythe locking elements therein tomaintain the shackle in its. closed and efiective position.

The freeends'of the posts 12 and 1301? the .U-shaped'shackle are upset, as atl tand 15,; so as to preventthewithdrawal ofthe shackle 11 from the lock casing, such upset'portions l land 15, however, permitting limited movement of the shackle fora purpose which later will be described. r r In assembling the shackle and the lock casing, alink at one end of a chain 16 is engaged with theshackle by passing one post thereof through the said linln'and afterthe shackle is inserted inthe lock, the free ends a of the posts 12 and'13 are upset asindicated, to permanently connect the chain 16 .withthey lock."

' The T-shaped lockinghead asindicated in I I Figs: 1 to 4, is a laminated structure constimediate filler 19 at one endi anda'separation at the other. The plates 17-and'18fwith the intermediate filler'l9 are connected by rivets :20, into" a solid unitary structure. The separated ends 17 and18 of the locking head re .ceive between them the link at the free end of the chain 16,-and a rivet 21- is passed through the said. ends 17'and18, and through thelink of the chain, and upsetso as to efiect --The head of the-T has a length which is greater than the distance between the posts 12 and 13 of the shackle,- so that when the T- shaped locking head is engaged with" the .shacldeinthe manner shown in Fig. 4, and

with-the'shackle moved inwardly to locking position as in Fig. 2, thelocking head cannotbe withdrawn therefrom, until the shackle is released by the operation of the key 22. The stem of the T-shaped locking head has a width at some point under its head, which is.

about equal to the distance between the posts .12 and 13 of the shackle. To prevent idle movement of the T-shaped locking head, when engaged by the shackle, I have provided the stem of the said head with notches in bled upon itself and riveted as in Fig; ,6.

- In operation, the 'keyx22 is -'turned to release the shackle. 11, and the latter is withdrawn to the position shown in Fig; 1, with stops 14 and 15 inengagement with the bottom of the lock. With theshackle in such position, an enlarged opening is provided,

;.through which ,the'locking head may be the lock casing.

passed and rotated a quarter turn, so as to lie with one ofits widersides against the top of The shackle is then snapped into closed position, as in Fig. 2, securing the locking head firmly within the shackle, and

I in a' position from which it cannot be withdrawn, until after the shackle has been freed for outward movement in the lock casing, by

operation of the key 22. The parts forming {the structure are of hardenedmetal and cannot easily be broken, thus aifording a security which may be relied upon. The improved locking'device is used byv encircling the an- 10 nular tire support'and the spare tire with its rim thereon.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

1. A spare tire locking device comprising a lock embracing a lock casing and a sliding U-shaped shackle, witha chain having one end'connected to the shackle and a locking head connected at the other, the said lockinghead having an enlargement adapted to be passed through the shacklewhen'the latter is in itsoutward position, and to be confined therein when the shackle is in its I inward position. I

2. A spare tire locking device comprisinga lock embracing a lock casing and a U-shaped shackle sliding therein and provided with means to limit the outward movement of the shackle, with a chain connected at one end to the shackle and having at its other end a 4 locking head provided with an enlargement adapted to be passed through the shackle when the latter is in its outward position,

and to be confined thereinwhenthe shackle is in its inward position.

7 ward position.

3. A spare tire locking device comprising a lock casing provided with a U-shaped shackle sliding therein, with means on the shackle to limit its outward movement in the casing, a chain connected at one end to the shackle and at its other end to a T-shaped locking head, the latter being dapted to be passed through the shackle when it is in its outward position, and to be confined against withdrawal when the shackle is in its inward position.

4. A spare tire locking device comprising a lock casing provided with a sliding U- shaped shackle, a chain connected at one end to the shackle, a locking head connected to the other end of the chain, the said locking head being composed of a plurality of plates united at one end and separated at the other to receive between them a link of the chain, thelocking head at its united endhaving an enlargement which is adapted to be passed through the shackle when the latter is in its outward-position, and to be-restrained from withdrawal when the shackle is in its in- 5. A spare tire locking device comprising a lock embracing a lock casing having a shackle with a chain connected at onejend to. the lock to prevent detachment and provided with a locking head at the other, the said locking head having an enlargement adapted to be-passed into the shackle when the latter is in its outward position, and to be confined therein when thefishackle is in its inward position.

6.. A spare tire locking device embracing a .lock casing and a non-rotating, U-shaped shackle fixed in the casing but having a limited, longitudinal, sliding movement therein, in combination with a flexible chain pivotally and permanently engaged at one end with the shackle and detachably engaged at its other-end with the shackle.

7. A sqare tire locking device embracing a lock casing and a non-rotating, U-shaped shackle fixed in the casing but having a limited, longitudinaL sliding movement there- 1n, in combination with a flexible chain pivotallyand permanently engaged at one end with the shackle and having at its other end an enlargement which may be passed through the shackle when the latter is in its outward position and be confined therein when the shackle is in its inward position, whereb the fsaid other end of the chain is detachably engaged with the shackle.

In testimony whereof,I have signed my name at Milwaukee, this 19th day of September, 1927.
