W. E. CLARK AUXILIARY LOCKING BOLT Filed May 23 1921 #165 fidomeys Patented June 12, i l? WILLIAM: ELGIN CLARK, OE MIIJNEAPOLIS, MINNESOTA.
AUXILTAR-Y LOCKING BOLT.
Application. filed May T 0 all whom it concern:
Be it known that T, VJILLIAM Enorn CLARK, a citizen of the United Eitatcs, resident of Minneapolis. in the county of Henna pin and State of Minnesota, have invented certain new and useful Improvements in Auxiliary Locking Bolts, of which the following is a specification.
This invention relates to improvements in auxiliary locking bolts and more particularly relates to such locking bolts adapted to use in connection with safes, vaults and similar receptacles or enclosed spaces employed for the safe-keeping of valuables. This novel locking bolt apparatus is used as an auxiliary to the usual locking bolts, locks, bars, etc., customarily employed at the present time in connection with the door of what may be generically termed safes. This auxiliary bolt is normally retained in inoperative or unlocked position but is adapted to be moved to operative position upon the plication of heat to the safe as by an at tempted burglarious entry throu h the use of a cutting flame. Movement or this locking bolt is caused by combustion of a charge ignited by the cutting flame, which combustion, explosive or otherwise, generates gaseous pressure to cause movement of the loci:- ing bolt to locked position. Movement of the locking bolt may be directly caused by the generated pressure or the locking bolt may be held in inoperative position against the force of a suitable tension means and the I generated pressure may indirectly cause movement of the locking bolt by effecting release of the device holding the bolt in inoperative position.
Applicant is aware that heretofore combustible or explosive charges have been employed in connection with safes so that, upon ignition of the charge, pro ectiles are fired, an auxiliary casing is fragmentized and blown ed, with the intent of killing or injuring the burglar. Not only is the value of the safe impaired or destroyed, but these devices constitute man-traps usually forbidden by law. This novel device does not injure either the safe or the burglar but provides an additional locking means and in cidentally functions as an alarm.
The object of this invention, therefore, is to provi e an improved auxiliary locking bolt for safes.

and accompanying drawings and will be pointed out in the annexed claims.
in the accompanying drawings, there has been disclosed a structure designed to carry out the objects of the invention, but it is to be understood that the invention is not confined to the exact features shown, as various changes may be made within the scope of the claims which follow.
In the drawings:
Figure 1 is a view in vertical section through the locking bolt, casing and associated. parts;
Figure 2 Figure 1;
Figure 3 is a view in section similar to that of Figure 1 but showing the charge adapted directly to move the bolt; and
Figure 4 is a section on the line 4-4 of Figure 3.
in the selected embodiment of the invention here disclosed, there is shown a casing 1 having a tube 2 of relatively thin metal supported at its ends in bosses integrally provided on opposed ends of the casing. The locking bolt 3 is slidably supported in the tube 2, being capable of longitudinal movement "from the retracted inoperative position to an extended locking position, as for example against the usual bolt work on a safe door, or its terminal portion may seat in a similarly shaped recess in body 01": a safe (not necessary to be shown). It is to be understood that, if: this casing 1 is mounted upon the body of the sate, then the recess will be in the door, and vice versa. The casin is aiiixed to the interior of the safe.
in the form shown in Figure l, the bolt is constantly under tension tending" to move the bolt to extended locking; position and is releasably retained in inoperative position, the combustible charge being employed to effect release of the retaining means whereby the bolt is moved to locked position. The tension is provided by means of the coiled spring 4 seated within the tube 2 and having one end abutting against the adjacent face of "he boss recess and its other end abutting against the adjacent end face of the bolt. The bolt is retained in retracted unlocked position by means of a dog or latch 5 pivotally borne by the stud? provided on the casing 1. The upper end of this latch is preferably beveled as shown and is adapted to enter the recess 9 pro vided in the under sir es of the bolt 3 a section on the line 2-2 of whereby the bolt is normally'held in relatch is in bolt-retaining position, forms a" closure for the chamber loprovided by a, breech-block 1Ov suitably riveted to the eastracte'd inoperative position; The combustible' charge is adaptedto efiect release of such retaining means. To this end g' the latch is provided with a head integrally projecting therefrom on the opposite side ofiits pivotal mounting. This head, when the ing. This chamber eon'nnunicateswith a rearwardly extending recess which is adapted to receive the combustible char 'e and to bethereby also closed. The COI'Ill'fllSlT-lblfi charge employed is preferably gunpowder although it istobe understood that various oth erisubstances may be employed which upon ignition will generate sufficient gaseous pressure in the chamber. charge here shown is in the form of a cari tridge shell 11 containing the gunpowder 12 at an intermediate portion thereof, for- "Wardly of the gunpowder in the shell 11 is positioned the wadding 16 while rearwardly is positioned the end face of a fuse tube 21 which carries afuse 1 1. The nut 13 isretothe block 10. As" is here indicated, the fuse-carrying tube 21 extendsoutwardlythrough the lockceived in' threaded engagement on the rear end of the breech block .10 and holds the shell 11 and tube 21 in vassembled relation ing boltcasing through an aperture there ,i n preferably surrounded by an annular shoulder; externally threaded to receive the aperture'd lock nut 19 thereon. The fuse may extend to positions along the interior surface'of the safeor door which maybe exposed to possibility of burglarious operation'of an oxyacetylene, thermit or other metal cutting flames or intense heat applications. I i i i The cutting flame generates suflicient heat to ignite the fuse which in turn ignites the gunpowder; or, it is possible that the gunpowder may be directly ignited. Upon combustion of the charge, gaseous pressure is created-in the pressure chamber 15 causing pivotal movement of the latch 5 and With-' drawal of itsbeveled end. from the recess 9 thereby causing movement of thebolt to exlatch is under tension of the leaf spring 6 anchored in the breech block 10, which presses against the adj acent-face of the latch recess 9 in the bolt 3. lMeans are provided which are tended-for locking position. Preferably the 5 to hold the same in engagement with the automatically operable, upon-movement of the bolt ,to lookingposition, .to maintain the bolt in such position. Such meansare provided by the dog 17 pivoted on the stud 20 carried by the casing 1. This dog is under tension 'ofpthe rleaf -spring 18 normally upwardly pressing the dog against the under face of The combustible l thebolt. Movement of the bolt to'l'ocking position permits the dog 17 to enter the angled recess 8 provided in the bolt 3 thereby preventing 'retractio'nof the bolt.
"The casing 1 is preferably integrally formed and is open on one side which is adapted to' be closed by thecover 22 of sheet metal which is securedfto the casing as by means of the screws shown in Figure 2. -Annularlyshouldered holes- 25 are provided through the casing for the reception of cap screws by means of which the casing 1 may be attached to the interior of r the safe. i
In the'modified form shown in Figure 3, the breech block 10 is mounted'in the tube 2 andthe'fusetube 21 rearwardly projects from the casing, the lock nuts 13 and 19 ,I
