Specification of Letters Patent.

Patented Dec. 19, 1911.

application filed September 16, 1911. Serial No. 649,678.

To all whom it may concern: I

Be it known that I, PAUL SZLUKA, a subject of the King of Hungary, residing at Iuionville, in the county of Lake and State of Ohio, have invented certain new and useful improvements in Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to locks, and more particularly to that type commonly styled a padlock.

The object of my invention is to provide a lock-body with a novel form of shackle that can be easily and quickly locked in a closed position.

I attain the above object by a lock consisting of comparatively few parts easily and quickly assembled.

The construction of throughout and easily by a key.

The construction of the lock is such that the mechanism thereof cannot be tampered with and the lock surreptitiously opened.

The invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, where in like numerals'of reference designate corresponding parts throughout the several views, in which Figure 1 is a side elevation of the lock in connection with a staple'and hasp. Fig. 2 is a longitudinal sectional. view of the lock. Fig. 3 is a cross-sectional, view taken on the line III III of Fig. 2; and Fig. 4 a similar view taken on the line IV--IV of Fig. 2.

A lock in accordance with this invention comprises a cylindrical body or barrel 1 having a longitudinal central bore 2 eX- tending from one end thereof to the opposite end The inner end of the bore 2 is ei'llargcd and the walls thereof scre\v--thr(; aded, as at Adjacent to the inner end of the body 1 is a recess 4 that intersects the bore 2 of the body. The lower closed endof this recess is disposed at an angle, as at 5, to receive a fiat head 6, carried by the hookshaped end 7 of a shackle-8. The outer end of the shackle is pivotally mounted between apertured lugs 9 by a pin or rivet 10. The apertured lugs 9 are carried by the side of the body 1, at the outer end thereof. The

the lock is simple locked or unlocked head 0 of the shackle has an openin 11 to provide clearance for a pin 12 locate Within the bore 2. The inner end of thepin 12 is enlarged and screw'threaded, as at 13, to screw into the threaded end of the bore 2. The inner end of the pin 1'2 has a shank or stem 14- and adapted to be mounted over, the shank or stem is the inner end of a key 15. This key has a socket 1G to receive the shank or stem 14. The shape of the recess lpermits of the head 6 being easily swung into and out of said recess. The pin 12 is placed in the bore .2 through the o ening of the head 6 and is rotated until the t ireads ot' the pin engage the threads 3 of the bore 2. The pin 12 is prevented from sliding out of the bore, and the key 15 can be inserted in the outer end of the bore to engage the pin 12, whereby said pin can be further rotated into the bore 2 to firmly lock the hook-shaped end of the shackle within the lock-body.

The lock is illustrated in connection with a staple 17 and a hinged hasp 18. The lock occupies a very small space in connection.

with the staple and hasp, and the hook shaped and of the shackle supports the lockbody in such a position that a key can be easily inserted in thc'samc and water or other matter cannot enter the keyhole of the lock.

The lock in its entirety is made of light and durable metal and car he made of various sizes.

What I claim is A look comprising c 'lindrical body provided with a longitudinal bore for the insertion from one end of a key, the wall of said here provided with threads at that end opposite the end of the bore in which the key in inserted, said body further having at one end a transversely o1....+nding inclined recess intersecting said bore, a shackle including a longiludimilly extending portion and a hook-shaped portion having the outer part thereof extcrnling inwardly at an inclination and enlarged, means for pivotally connecting extending portion upon one end of said body, said enlarged part of hook-shaped portion of said shackle having an opening and capable of extending in said recess and across said here, a pin extending in said here and having its outer portion engaging one end of said longitudinally said threads and projecting through said In testimony whereof I aflix my signature opening for securing the hook-end of the in the presence cf two Witnesses.

shackle in operative position, and said pin of a length as'to extend in proximity to the PAUL smooth end of said bore and reduced for the Witnesses reception of a tool to facilitate the position- IDA E. CHAFFEE,

ing and removing of the pin. ALMA J. ADAMS.
