VAULT Loon.

Application filed January 2a, 1924. Serial nblje'aalsz. I

To all whom it may concern:

Beit known'that we, GEORGE M. FARA BOUGH and Gnome G. MOUTRAY, citizens of the United States, residing at Rogers, county of Benton, and State of Arkansas, and WVichita, in the county of Sedgwick and State of Kansas, respectively, have invented certain new and useful Im ro'vements in Vault Locks, of which the following is a specification. v

The presentinvention relates to a vaultlock and more particularly to a device which I- designate as a daylight protector to be inf stalled on a vault door of abank or like institution.

The principal object of theinvention is to prevent bank robbers and the like "from looking the bank employees ,i'n'the vault. The installation of this protector allows the door to be closed with the exception of about one inch. When in this position it automatically looks so as to remain in this position and-the door cannot .be further closed nor can it be openedfrom the outside without the use of a specially built tool. This arrangement allows the occupants of the vault to be in perfect safety during robbery and also allows them to have sufficient air. The door of the vault may readily be unlocke'd'from the inside.

Another important obj ectof theinvention is to provide a device of this nature possessed of a simple and efficient construction, one which is reliable, comparatively. inexpensive to manufacture and install, durable, and well adapted to the purpose for'which it is designed.

With the above andv numerous'other objects in View, the invention resides in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a fragmentary horizontal section taken through a vault and the door thereof showing my locking device associated therewith for holding the door in a 5 partially closed position,

Figure 2 is a section taken through the vault vertically substantially on the line 2-2 of Figure -1,

gigure 3 is a perspective view of the lock, an

, Figure 4 is a fragmentary elevation thereof showing particularly' the latch.

Referringito the dr'awingin detail it will be seen that 1 designates the vault which i is provided with the usual door 2. The portions of the vault and the door which abut each other are usually provided with a stepped construction as indicated at 3.

The parts thus far designated are'of a conventional construction and they are merely illustrated by Way of example so as to more clearly explain the operation and utility of the look about to be described.

The preferred embodiment of the lock consists of a supportingbar 4t fixed to the innera wall'of thevaultby a plurality of bolts 5 or in any other suitable manner. This supporting bar 4, is'provided at its end adjacent the doorf2 with an offset ex tension '6 spaced from the inner surface of the vault wall. An extension bar 7 forming the body of the lock is attached 'to'the ofi'set extension 6 by means of bolts 8 or in any other suitable manner. This body extension 7 V and the upporting bar 4 are disposed horizontally and the body extension 7 is positioned adjacentthe door 2. A latch bar 9 is pivoted adjacent one end to a bolt 10which is supported by the'body 1 extension 7 adjacent one end. The outer end 11 of' the latch bar is curved and a notch 12 is disposed or formed on the under edge thereof adjacent the curved end 11. As is disclosed to advantage in Figure. 1 the latchbar 9 is pivoted on the inner face of the body extension 7. On the outer face ofthis body extension 7 there is positioned a spring member 13 disposed vertically and held in place by bolts or screws 14 and 15. The bolt 14 pierces the body extension 7 and extendsbeyond the inner face thereof so that the latch bar 9 may rest thereon in a substantially horizontal position as is indicated to advantage in Figure 4. A rod 16 pierces the body extension 7 intermediate its ends and is provided with an inner head 17 and an outer head 18. A spring 19 of the compressible helical type is positioned about the rod16 between the'outer surface of the body extension 7 and head 18 so as to normally hold the inner head 17 against the inner face of the body extension 7. As is disclosed to advantage the inner end of the head 17 and rod 16 is so disposed as to abut the inner end of the latch bar 9 so that when the latch bar is in a substantial horizontal position it is impossible to swing the same. Furthermore, if the rod 16 is pushed inwardly this latch bar may be readily swung to an angular position in relation to the body extension and will be held in this position when the head 17 returns into abutment with the body extension. If the latch bar 9 is swung to a vertical position the lip extension 20 of the spring member 13 will frictionally engage one face thereof and hold the latch bar in this position.

A keeper 21, substantially L-shaped in formation has one of its legs fixed to the door 2 and the other leg is engageable by the latch bar 9. l/Vhen the vault is opened, the latch bar should be disposed in a substantial horizontal position. If, now, the door 2 is closed the bolt 9 will engage the keeper so that one leg of the latter will be disposed in the notch 12 thus holding the door ajar. It will be readily understood and seen that this door cannot be opened or closed from the outside when in this position and with the space provided by the door being aja'r will allow plenty of ventilation for any occupants of the vault. The occupants of the vault may readily release the lockby pushing inwardly on the rod 16 and lifting the latch bar out of engagement with the keeper.

The construction and operation of this invention should now be clearly understood without a more detail description thereof. It is, however, desired to point that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or soopeofthe invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described our invention what we claim as new is:

1. A device of the class described including in combination a support, a latch bar pivoted adjacent one end to the support, a push rod piercing the support and slidable transversely therethrough, a head on the rod disposed when in abutment with the support so as to prevent swinging of the latch bar, and yieldable means normally holding said head in abutment with the support.

2. A device of the class described includ ing in combination a body, a latch bar pivot ed to the body, a pin projecting from the body for supporting the latch bar in substantial alinement with the body, a rod piercing the body and movable therethrough, a head on the rod adapted to abut the body adjacent one end of the latch bar when alined with the body so as to prevent swinging thereof, and a spring associated with the rod to normally hold the head in abutment with the body.

3. A device of the class described including in combination, a body, a keeper, a latch bar cooperating with thekeeper and pivoted on the body, positive manually releasable means for holding the latch bar in an up wardly swung released position or a horizontal latching position, and means ar-. ranged to frictionally engage the latch bar to hold it in a released upwardly swung vertical position. A

4. In combination, a vault having a door, a latch in the vault, a keeper on the door adapted to be engaged by the latch when the door is nearly closed to hold the latter in a partly open position, and means for releasably holding the latch in latching and released positions, said last named means be ing located within the vault a distance from the door so as to be non-releasable from a In testimony whereof we affix. our signa tures in presence of two witnesses.
