Be it known that I, FRANK Somer, a citi- Zen of the United States, residingin Philadelphia, Pennsylvania, have invented certain Improven'ients in Chain Locks, of which the following is a specification. n K VOne object of my invention is to provide a padlock with a shackle in the form of` a chain and to providemeans for securing the loose end of the chain to the lock casing at any point desired.

.A further ob 'ect ofthe invention is to provide a bolt which can be pushed into engagement wit-ha chain by hand, 'but which must be retracted by the mechanism within the lock. j l l A still further object of the invention is to construct a chain lock in such a ymanner that the lock casingand the mechanism may be made standard, and the keeper having va channel for the passage of the free end of the chain canbe made of different sizes to fitdifferent types of chain and can be attached to a standard casing.v y In the accompanying drawings; n'

Referring to Figs. 1 to 8 of the drawings, 1 is the casing of the lock made in two parts in the usual manner. Located within the casing is a bolt 2 actuated by mechanism .which will be' described hereinafter. 3 is a types.

chain, whichmay be. of any of the usual has a body portion located within the casing. This .body portion isperforatedffor the passage .of the pin 5.k The lockcasing vmay be cutaway? to receive the clipsothat the clip will beheld rigidly in position.

Secured to one side ofthe casing in line 6, in the present' instance, is secured tothe casing of the lock by rive-ts 7, which are preferably co-untersunk, as shown, but other means of fastening maybe used if rfound more des1rab'le.

The chain is secured to the casing, `1n the presenty instance, by va clip 4, which When the bolt 2 is projected, vit extends i into the channel and. passes through `one of theflinks of the chain', as clearly shown in Figs. 2 and 3, locking the chain firmly to the casing.v The locking mechanism .con`

sists of a

latch

8, 6 pivotally mounted `on the pin 5, an actuating plate 9,and one or more tumblers 10, pivotally mounted on vthe pin 11. Each tumbler has the usual l.spring 12 and is notched to receive the stump 113 carried by the .actuating plate 9. yThere may be asmany of the tumblers as .desired and the notches in the tumblers will be indifferent positions, according to the, combination desired.

",'The bolt is notched at 141 to receive the projection 15' ofl the latch. hen theprojectionv vis in the notch 111, it prevents vthe withdrawal. of the bolt. It is held in the notch by. aspring 16. 'On` the latchl is a projectionf17, which extends into a recess in the plate 9 so that, kwhen the plate is shifted in the 'direction `of the arrow (Fig.

v7) by the key, it turns the latch on its pivot and vforces the projections 15 out of the notch 14,' freeing v the bolt, which is forced back by a spring 19 that bears against4 the pin 2O on the bolt, lthe spring being j pivotally mounted on the pin 21 of the'casing. The plate 9 is slotted at 22, 22, so

that it will slide upon the

pins

24 and 11..y

In the presentv instance, the stump 18 has an extension 13a, ,whichv projects over the free ends" of the tumblers, keeping them in position on the pivot pin-11.

It will be .seen bythe above construction that the bolt iS free to be manually pressed into engagement With the chain and, when in engagement, the latch Willjei'rterthe notch in the bolt, holding it in its locked 'position against the pressure of the spring 19. When it is desi-red to release the bolt, a key is ifn- .serted in the key post 25 and turned so as to Cause `the tumbler to align With the stump of the actuating plate. On the continued movement of the key, the plate Will be shifted and Will move the latch out of engagement with the bolt, allowing the bolt to be Withdrawn by the spring 1'9, thus freeing the chain. A lug 26 'on the bolt lcomes in contact With the pin 24 so as to limit the Withdrawal movement of the bolt. The chain can be of any length ydesired, accordi-'ng to the usetor Which the lock is intended.

In Figs. 9 and l0, the keeper l6 is 'shown separated from the lock casing 1. By making the keeper separate from the casing ,a standard l'oc'k casing can be 'assembled With any size -or type `olke'eper desired, depending, somewhat, on the character and. size ot the chain. j

In Fig. Il, a light, narrow chain is illustrated `and in Fig. 12 another type 'of "chain is shown. The keeper must be of su'chs'ize as to hold the chain properly When the bo'lt is projected.

In Fig. l1, a pivoted plate 9a stead of a Isliding plate. This pivoted plate 9 has a key stump i3d and is so shaped as to be actuated by 'the key. As it turns on the pivot, it will raise the latch 82L out of engagement With the bolt 2, and, on the continued movement of 'the key, it will come in contact with the short arm ot' the lever, which actua-tes the bolt so as to' retract 'the bolt by lthe key instead of by a spring, as in Fig. 2.

The construction may be modified, as in Fig. 2, in which `the pivoted latch 8b engages the bolt 2b and is actuated by the key. Vards 27 may be located on the pins, as shown.

I claim:

1. vThe combination of a casing; a 'chain 'attached at one lend tio the casing; a keeper at the l'side of the casing forming 'a channel for vthe passage of the free 'end of the chain;

is shown, in'- to be projected 'into the channel and into engagement with the chain; a 'spring for retract-ing the bolt, said bolt being notched; a

pivoted latch having a projection adapted to the notch; an actuating plate engaging the latch, said actuating plate carrying astump; and a tumbler, the tumbler and the plate being arranged to be actuated by a key so as to Withdraw7 "the latch and allow the bolt to be retracted by its spring. A

2. The combination in a chain lock, of a two-part casing; a chain; a clip at one end of the chain, said clip being perforated; a pin in the lock casing extending through the 'pe'rforations in the clip; a keeper on the casing forming a channel for the passage of the :tree end of the chain; a sliding bolt in the casing arranged to be rojected into the channel; a latch pivotally mounted on the pin that passes through the clip, said latch having a projection; a notch in the bolt into which the projection extends; a spring for retracting the bolt; a sliding actuating plate carrying a stump, said plate being recessed; a second projection on the latch extending into the recess; and a pivoted tumbler notched to receive the stump of the plate.

43. The combination of a casing; a keeper attached thereto at one side thereof; a chain, one end of the chain being attached to the casing and the other end being free to pass through the keeper; a bolt in the casing arranged to engage a portion of the chain in the keeper; a latch engaging the bolt; a sliding stump-carrying plate arranged to yactuat'e the latch; a tumbler; and means for retracting the bolt Whenjreleased.

4. The "combination in a chain lock, of la casing; llocking mechanism therein including a bolt; a keeper made separate from the casing and adapted to be attached thereto; means for securing the keeper to the casing, whereby keepers of different size or shape may be attached to the casing; and a chain, one end of which is secured to the casing and the otherpend of Which is adapted to pass through the keeper forengagamen-t by the saidbol't. ,Y FRANK SOLEY.
