To all whom t may concern.'

Be it known that I, ALFRED J. MACY, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in an Automatic Safety Lock for Vault and Safe Doors; and I do hereby declare that the fol- ,f lowing is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of tliisspeciiication.

This invention relates to an auxiliary'lock for safes and vaults which is designed to l stalled thereon. f

function if ,the regular look should be unlawfully tampered with.

An important obj ect of this invention is to foil a burglar by utilizing any action in tampering with the usual combination, time, or

cylinder lock, to throw, an automaticv emergency lock into locking position toA prevent retraction ofthedoor bolts. r

A further object of this invention is to provide such a lock which is adapted to-b'e iitted to vaults and safes nowin existence so that any owneror user can install-this safety device to further protect the contents of said vault or safe against unauthorized persons. I

A furtherobject of this invention is to allow placing the device in various 'locations in different installations so that even if the burglar knows ofthe existence of this emer-v gency lock he cannot reach the same by drilling through the door because nothingon the outside of the door shows where said device is installed, and with said devicea hole would have to be located within small limits to enable anyone to release said lock.

A further Objectis to construct such a device in such a way as to lit vdoors of various widths and constructions without requiring special parts for each installation.

A further object `to be obtainedhin the construction "of thisdevice is to make it of.

standard parts or elements to avoid expensivespecial machine work of any sort.

An object consists informing the bottom 'more fully described.

of the gravityl actuated member .to prevent its lodging on some obstruction in its downward path, theV point thereon causing the weightto fall off such Obstruction and thus? complete its function.

Other and further important objects ofr this invention will be apparent Yfrom the dis# closures in the specification and the accompanying drawings.

The invention (in a preferred form) is illustrated in the drawings and thereinafter O n the drawings; Figure l showsa rear elevation vof a vault door with the deviceof,y this inventionv in- Figure 2 is an enlarged fragmentary ele-l vation of the device shownin' Figure l with the component parts clearly shown. f'

As shown on the drawings:

A description of thev device as installed in an ordinary vault follows, it being understoodlv that the invention is not limited to the vault construction described and that said device may -be'built-'in a variety of ways suited to otherl dooi` constructions.

In the diagramitfiaticviewl of the vrear of the vault door shown in Figure l, the numeral 1 refers to a plate used as the front and principal part of the door, with a frame Or casing 2 fastened to the same to hold the bolts 3 which lock the door by sliding into holes in the walls ofthedooropenin'g.. The several bolts 3 are clamped'or bolted together by bars 4"so.a s to slide as one piece whenthe doorfhandle (not shown) lis moved. In the usual construction of Avault doors the bars are locked in extended position by. some form' of tumbler, combination',` cylinder, time, or similar lock 5. It is to be under along the line 5 5 of Y stood that the above described construction of the door is immaterial to applicants invention, the description being inserted to render clear the application of said invention to one particular form of door.

A device embodying the present invention is shown in detail in Figures 2 -to 6 inclusive, where a weight 6 is hung from an internally threaded reel or nut 7 by a ribbon or cord A8 -of some suitable material which is wound on vsaid reel with theinner end of said ribbon or cord fastenedY to said reel.

The reel is rotatably 'mounted on a threaded shaft 9 which is slidably but not rotatably supported by tubes l0 and 10, and which are secured to a plate or bracket 11. rlhe tube lOf-is preferably just long enough to contain the threaded shaft 9and the end of a coupling l2 to connect to further lengths of tubing 13 to span the space between first length oftubing and the frame 2 in connection with an `ordinary nut lll mounted on `a threaded adjusting shaft l5. The edge of the plate ll nearest the swinging end of the door vis provided with two inserted hardened points 16 as shown in the enlarged view in Figure 6, and the end of the adjusting shaft l5 is also provided withv two of these points 116. `The object of said points 1'6 is to hold the assembly in place on the door by being forced into the frame 2 by the tightening nut le against the last piece of tubing 13.

' The adjusting shaft l5 is made long enough so that in connection with two or three different lengths of stock tubing the device can be fitted to varying widths of doorslwithout requiring special machine work for each particular installation. y

ln the openzI pos-itionthe weight 6 isheld up by a trigger 17 loosely mounted on a stud '18 on-the bracket or plate `1l, said trigger being held substantially horizontal by a fragile connection or cord 19 carried from a hole in i-tsend to any stationary part of the-lock 5. ln the open position the threaded shaft 9 is retracted sufficiently to clear the bar i when the bolts 3 are in the retracted orunlocked position, i. e., when the door is unlocked and free'to open.

The operation is as follows:

Then the regular'vault lock is operated in the usual fashion, applicants emergency7 lock is unaffected and reina-ins open because the cord 19- is attached to a stationary part ofthe lock and therefore is not disturbed. Should an attempt be made to force the regular lock or remove same by any-irregular means, such as drilling or burning around it and reinovingthe same entirely, or prying the saine out or driving it in, the fragile cord 1.9 will be broken, releasing the trigger 17 which allows the weight 6 to drop, unw'inding the cord 8 from the reel 7, thereby revolving said reel on the threaded shaft 9, projecting said threaded shaft outwards against the bar 4, thereby temporarily locking the entire door mechanism against any possible manipulation from the outside. To

enable the rightful owner of the vault orsafe to gain admittance after an attempt at forcing entrance, a record of the exact position of the reel 7 'should vbe made at the time of installation so that by measuring from the edges of the door on the outside a hole canl be drilled to 4allow reverse rotation "w of the various parts of the vdevice will readily suggest themselves, and'I therefore do notipurposelimiting myself Iotherwise than necessitated by the `priorI art.
