LOCK.

Application led November 29,v 1922. Serial No. 603,974.

l Capableof Ybeing-opened and .closed `by a i slidable movement of the locking mechanism along the shackle rods. a

. ,ln device of my .invention described in United 4States(Patent/No. 1,452,393, dated.

April l?, 1923, I have describeda lock of the same general j character in which the shackleis formed of one rodbenttothedesired form, inwhich the.v opening between the spaced ends of the `shackle rod is bridged by the-containercarryingthe locking meche anism lwhen the device is in locked position.

En the device of-that-application, yit .is necessaryto move the container along the shackle fora distance at leastpequal` to the opening in theshacklej necessary forithe admission of the article whichV it is desired to maintain in a locked'position with regardlto the lock. This requiresa shackle of considerable length, as the opening operation must necessarily be at .both l ends of the shackle rod.

"The ldevice of this application overcomes theabove-mentioned objection, as, due to the hinged members of the shackle, thefcontainer need be moved only avery short distance, that is, just suficient to releasethe rod endL from the container engagement, the released rod then being capable `of movement uponaits hinge to open' ther shackle to its full extent. Y l

`Furtherinore, when` the two articles to be locked together, as, for instance, the wheels ofa baby carriageyare separated from each other by the approximate length yof the shackle, `an unhingedshackle can not be eniployed, as the articles can not be inserted through the shackle openings.

My present invention overcomes this ydifficulty, because of 'the hinge movement, vthe shackle ends can be employed to encompass e5 articles so positioned.

VMy device, therefore, presents new and valuable features not possessed by my formerly described invention, which will be further evident upon a consideration of my drawings and specification. In the accompanying drawings, illustrating one form of the device of my invention, similar parts are designated by similar numerals.

Figure 1 is a perspective view of one form of the device ofV my invention in closed and locked position.

Figure 2 is an enlarged front plan view of Figure 1 with the front plater of the container removed to show the locking mecha nism.

Figure 3 ,is section through the line 3-3 of Figure 2 with the front plate of the container in place.

Figure 1 is a section through the -line 4 4 of Figure 2.

YFigure is aperspectiveviewlof the container with the front plate removed.

rllhe particular form of the device Vofmy invention, shown in the accompanying dran# ings, comprises a Y shackle formed by the rod 10, to which arehingedly attached the bent `rods 11 and v12 at -13 and `14e respectively, the ends 15 and16 of the rods 11 and A12 beingspaced `from each other.

In order tostrengthen the hinge 14, and to protect it from being tampered with, l affix the gua-rd 17 by welding, or otherwise, to the rod 10, theannular member 18 bc ing also aiiiXed tothe rod Y10. rilhe guard 17 has thefixedly attached `pivot red 14- whichrextends through an opening in the annular end memberi19 of the rod 12 and into an annular bearing withinthe member e5 18. By these means, the pivot 14 is pro tected and enclosed within the guard 17, the latter acting` as a stop forthe opening and closing movements o'f the curved rod 12.

A similar guard 20 and pivot 13 are em- 100 ployed in the other hinge movement between the

rods

10 and 11.

'Slidable along the shackle-is a container comprising the member 21 with the surrounding flange V22 and the member' 23 with los the surrounding flange `24, the flange 22 having the

recesses

25, 25 and the flange 2li having ythe recesses V26, 26 for the passage of gli the

bars

11 and 12 therethrough. The liange 22 has the

recesses

27, 27 andthe lange 24 has the recesses 28, 28 'for the passage of Vthe bar 10 therethrough.

. The container member 23 carries `the two extended

members

29, 29 having a plurality of extended

pins

30, 30, which are capable of passing through openings within the container member 21 as a means of holding the two container members together.

rllhe pin 31 ot the member 23 is capable of receiving the hole of a key inserted through the keyhole 32 of the member 21, the stop pin 33 limiting the movement of the key. Y

A locking member 34 has an extended arm 35 slidable through an opening in one member 29 and capable of beingv inserted into, and withdrawn from, an indent 36 in the rod 10, the other side 37 of the locking member being placed within and slidable through,

a recess in the opposite member 29, the movement being limited by the shoulders 38, 38.

The edge face of the locking' member 34 has an indent 39 so positioned that the revolution of a key around the pin 31 will move the locking member from engagement with the indent 36 of the rod y10, the key,

when abutting upon the stop-pin 33, prevent-VV ing the return Vmovement of thc locking member 34. Y

When the key is revolved into normal position, the spring 40 will return the locking member 34 into engagement Vwith the indent 36 of the rodV l0, thus locking the devlce.

The figures shown in JJ-ull lines indicate th device in locked position, the locking'member 34 being engaged within the indent'36 of theV rod 10, thus maintaining the containerV across the space between the ends of the

rods

11 and 12 and preventing it from slidable movement along the shackle. The movement of an inserted key will move the locking member from engagement with the indent 36, allowing the container toV be slidably moved along the shackle.

When the container is moved downwardly, the end of the rod 11 will be freed from engagement with the container and can be revolved outwardly upon the hinge 13, as shown in dottedlines in Figure 1, thus allowing it to be placed around an object and revolved to its original position.

When the container is moved upwardly, the end ol? the rod 12 will be freed from engagement with the container and lcan be revolved outwardly upon the hinge 14, as shown in dotted lilies in Figure 2, thus allowing it to be placed around an object and revolved to its original position.

If the key is now removed, the spring 40 will bring the member 35 of the locking member 34 in compressed abutment against the rod 10 and, if the container is movedl downwardly, the member 35 will enter the indent 36 of the rod 10, thus locking the container across the space between the ends of the

rods

11 and 12 and preventing the re-V Y Y 7c It is evident that, in the form ofV my de-` moval of the locked objects.

vice having hinges in the shackle, it is not necessary to move the container so that the space between the container andthe end Vof either of the rod 1'1 or the rod 12 is'suiiicient to allow of the introduction of the article to which it is to be locked, as it is suflicientV to move it only until the end of one of the rods is free from the container, the hinged' movement allowing of the openinv of the shackle. Y Y

his is a most valuable Yfeature of my device in that it allows of a much shorter shackle than is necessary in an Vunhinged device, thus being much more economical in construction and more convenient and eilicient.

I donot limit myself tothe particular size,'shape, number or arrangement of parts, as shown and described, as these are given soV simply as a means for clearly describing my invention. Y

Vhat I claim is l l. In a lock, in combination, av shackle comprising a straight rod, aY bent -rod edly attacrhed to each end thereof, the end portions of the hinged rods being capable of placement in a plane Aparallel to the straight rods with their extremities spaced from each other, a container capable of slidable movement upon the shackle to bridge the opening between the bent rod extremities and to release each bent rod from retention therein, an indent within the straight rod, locking means carried by the container capable of insertion within the indent to lock the container Jfrom movement when it bridges the opening between the bent rod endsY and means whereby-a key movementwill remove 'the locking means from the indent allowing a movement to the container.

3. In a lock, in combination, a shackle comprising a straight rod, a bent rod hingedly attached'to each end thereof., the end portions of the hinged rods being capable of placement in a plane parallel to the straight rods with their extremities spaced from each other, a container capable of slidable movement upon the shackle to bridge the 0pening between the lbent rod extremities, and to release each bent rod from retention therein, an indent Within the straight rod, looking means carried by the container capable of insertion within the indent to lock the oontainer from movement when it bridges the 10 opening between the bent rod ends, means whereby a key movement will remove the looking means from the indent allowing a movement to the container and spring means whereby the locking means will be returned to its position within the indent when the key movement is released.
