u 'This invention relates to an improvement in handcus or shackles; and by the term fzvhandcus? as hereinafter used I wish to be understood as' including either devices adapted for use as handcuffs ormade ofsuf-V icient size to be used as leg-irons, the object of the invention` being `to produce at -a re. duced cost for manufacturev handcuffs constructed with particular'reference to lightness,-simplicity, fewness of parts, and 'Y seeA ,curity` againstv being picked by the pris'- oner.

Handcuffs or shackles as usually employed are arranged inpairs;` but for the purpose of illustration only 'one handcuff is shown.

vEach cuff consists of a body or case 2, to

which a chain 3 is swiveled inthe usual way, and to one end of the casean arm 4 is swiveled, they-outer end of the arm being formed with locking-notches 5 and adapted to 'pass' through Van opening 6, formed `for it inthe case, the ycase being openaty one side and closed by a cap 7 in substantially-the usual manner. In the case near the locking end is a circularrecess or chamber 84, and from this chamber a channel 9 extends into the opening 6.` vIn the bottom1o'f the chamber* are twospring-studs 10 and 1,1, and in the center ofthe chamber is a lpost which will yhereinafter be termed the key-post7 12. Lo-

connected with this disk by a ylink 14 is a locking-bolt 15, -the bolt being arranged in. the channel and having a nose 16 ada :ted to engage the notches 5 when .the end ofte arm passes through ,thev opening 6, the end ,of the' having a slot 17 to permit yof more or less independent movement between vthe bolt .and

be entered into the'hole18` in the disk. 'The hub of this tumbler is also formed .with an angular recess 23 toreceive acorrespondinglyshaped key to rotate said tumbler.

Mounted inthe case .atone. side of. the chamber 8 vis a spring 24, the upperarm 25 of which extends into the chamber and against the rear end of the bolt 15, soy as to normally force 'that bolt forward. Mounted in the cap-plate 7 near thekeyhole 26, is a spring push-button 27, which will bear upon the upper face of the tumbler yand so that the tum-4 bler may befdepressed. In the locked position, as shown 1n Fig. 2 of the-drawings, the

holeflS in the disk stands over thespring-pin 10, by which .the diskais held against rotation, and in this position .the bolt 15 isthrown forward, so as to standin `the opening 6 andengage with one of thenotches 5 of the arm, and hence lock that end of the arm to fthe case. To open the handcuff, .a key is inserted through the hole 26 and into the angular `recess 23 'in the tumbler andthe tumbler forced downward thereby against the ypressure of the spring 20 until the pin 22 in the under freefto rotate therein is a locking-disk 13, and I nk 14, which is connected with vthelbolt 1.5,.

IDO

faceofthe tumbler. depresses the spring-pin 10, so as to releasethe disk 13e. If then the key be turned, Vthe disk will be rotated by the engagement of the tumbler f'therewith -either by the continued pressure, so 4as to hold fthe piny 22 in thehole' 18, or by the en agement of the ltumbler with thestud 19.' l hen the disk is rotated to its'unlocked position, the hole 18 will stand over the spring-pin 1 1' which isthenforced u ward into ,the hole. 15

and Se @elite heldthe .,iekiirlitsseleekedfpof IlO sition. This movement of the disk will have turned-the link 14, so as to withdraw the nose of the bolt 16 out of the opening 6, leaving the arm free to be moved back and forth therein or entirely withdrawn therefrom. lf now itbe desired to lock the cuff without the use of the key, the spring-button 27 will be depressed, and this inward movement of the button forces the tumbler downward, so that the pin 22 carried thereby will depress the spring-stud l1, thus releasing the disk 13, at which time the spring 24 will act to force the bolt forward, so that the nose 16 thereof is in position to engage with the notches 5 of the arm, but the bolt is free to move rearward. This permits the arm to be passedgagement with the spring-stud 10, in which position the bolt 15 is held against movement in either direction, and thereby securely locks the arm in the case-in other words, doubly locks it in a closed position. It will thus be seen that while the cuH cannot be unlocked without a key after being opened by the key the keyV may be removed, yet when placed upon a person can be immediately placed in condition for operation by a mere pressure upon the spring-button 27.

Instead of providing the spring-button 27 to be moved inward against the face of the tumbler a slide 28 may be arranged upon the inner face of the cap 7, as shown in Fig. 6, this slide having a beveled nose 29, adapted to enter between the top of the tumbler and the inner face of the cap, so as to force the tumbler downward when the slide is moved against it, the slide being connected with a thumb-piece 30 on the outside of the cap for operation in the same way as was the springbutton 27, except that it is moved longitudinally instead of bein pressed inward.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The herein-described improvement in handcuffs comprising a case, an arm pivoted thereto and adapted to pass through an opening in said case, said case formed with a chamber having a spring-pin mounted therein, a channel extending from said chamber to the opening for the arm, a bolt located in said channel to engage said arm, a disk mounted in said chamber and connected with said bolt, said disk formed with a hole adapted to engage Vwith said spring-pin, and a tumbler adapted to engage with said disk whereby the said disk may be rotated, substantially as described.
