FERDINAND UNGKRICH, OF GALION, OHIO.

VAULT-CLOSURE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed April 18. 1907. Serial No. 368.912.

To all whom it may concern:

Be it known that I, FERDINAND UNCK- nIoH, a citizen of the United States, and a resident of Galion, in the county of Crawford and State of Ohio, have invented a new and Improved Vault-Closure, of which the following is a full, clear, and exact description.

This invention relates to vault closures, and is particularly useful in connection with devices of this class intended for locking and hermetically sealing grave vaults.

The object of the invention is to rovide a simple, strong and durable vault ciosure by means lof which the vault opening can be 1securely locked from the outside and which drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is an elevation of the inner face of my vault closure showing the locking mechanism in an operative osition; Fig. 2 is a similar view of a part o the invention showing the locking mechanism in an inoperative sition; Fig. 3 is a vertical section on the liiie 3 3 ofl Fig. 2, showing the4 closure locked in position upon the vault opening; Fig. 4 is a similar view showing the locking mechanism in position, hermetically to seal the vault opening 5 and Fig. 5 is an elevation of a detail.

Before proceeding to a more detailed explanation of my invention it should be understood that it is desirable in many cases tol provide grave vaults and the like with strong, durable and hermetically sealedclosures for the openings thereof to prevent unauthorized, admission to the vaults and to insure the preservation of' the contents of the same. l provide a vault closure comprising a door-plate adapted to seat againsta door-frame; the plate and the frame are preferably of steel, iron or the like.

The door-frame may be secured at the vault opening by means of bolts or rivets, or

in any other suitable manner, depending upon the construction of the vault, whic may be of metal, stone-work or the like. Slidably mounted upon the inner side of the door-plate are bolt members which can be rejected toward the edges of the door beiiind the lateral anges of the door-iframe, thereby locking the door in positionagainst the frame. The bolt members are projected by means of a rotatable cam having'lobes engagingwith the bolt-members to thrust them outwardly toward the edge of the doorplate when the cam is rotated. A key-bolt member is arranged near the center of the door-plate and has a threaded part located in a suitable threaded opening in the cam member. The key-bolt presents a square head at the outer face of the head by means of which the operating mechanism may be actuated through the 'aid of a suitable wrench or Spanner. A frangible member cor'nprising preferably a soft metal plug serves to secure the cam member to the key member, so that when the latter is rotated the cam is similarly actuated to project the bolts.

When the bolts are projected to the limit ot' their movement the rotation of the cam member is resisted, whereupon the frangible member is broken. the key bolt member is free to turn in the threaded opening in the cam member, whereupon the cam is forced outwardly from the face of the door-plate and carries with it by means of a projecting shoulder the bolt members. By thus forcing' the bolt members outwardly the door-plate is clamped against the door-frame to effect the hernie-tical sealing of the vault openings.

Referring more particularly to the drawings, 1 represents a vault having an opening with the door-frame 3 arranged therein. The door-frame 3 has an inwardly disposed flange 4 and is secured in place by means of screws or rivets 5. Seating against the doorframe is a door-plate 6 having a projection 7 adjacent to the edge'and presenting a curved surface 8. The projection 7 extends all the way around the door-plate.

The outer face of the door-plate may-bek provided with the usual central'boss 9 and strengthening ribs 10. A key-member 1,1 is carried xby Athe door-plate andy has a squared head 12 projecting beyond the outer face thereof. has a threaded part 13 extending beyond the inner face of the door-plate,` and it is furthe' When this takes place.

The key-member 11 E 110 .'1'5'f201a'nd the shoulder 14 are provided lateral recesses in which is located a .metal lug 21 constituting afrangible" -membexya apted. normally to 'connect'y the andA the lkey-member and to."l secure v'them together.

- Bolts22 are slidably mounted upon the inner faceoftlie door by means of suitable guides and are movably seatedon thev rojecf tion7 of thedoor. The bolts are. pre erably triangular i-n form andhave toes'23l at the' pides' adjacent to the edges of the door, the.' exes of the' triangles extending toward 'ie center of thedoor-plate and presenting rounded edges 24 and shoulders 425. The 8 6 bolts' are cut away near the middle lpozions 'to' form guide-bars 26 arranged in guides 27 carried by the door. The guides are formed by plates 23 riveted vto the door face and having laterally disposed ilanges 2 9. 'lhel .bolts 22 have slots 30 in which are located 'projecting lugs 31fcarried by the door and lntegral' with 'the projection 7. Arranged between the door and the end of the slots30, "'arehelical s rin s 32 which force the bolts '-ia'wayfrom the e ge of thedoor towards the center thereof. The lugs 31 have trans, versely projecting ins' 33 adjacentfto the outer faces ofthe olts, adapted to retain' the same in position. The\pins33 are ar M 'ranged substantially in alinement with the rproJections 7and arethus adapted to serve as Yulcrums when the b'olt' members are :rocked upon the projections 7 by the movements of the cam member awayfromthe 'doorlfaceL The o eration-loimyinvention isas follows: Beforethe closurel is placed in position' upon the opening -of the vault,the bolts are di'g'zlwninto -the'position shown in Fig. 1, the dog 1 9 being lifted from engagement with the ratchet 17 necessary, to rotate -the key' member in the reverse' direction to the lock--v movement. In the positionindicated in Fig.' 1 the shouldersof the lobes 16 of the. cam rest the shouldersof thev bolts. The door is thenplaced in position with the` edges-seatinga t the flanges ofthe door-g asket 34 being partlandthesaid bolts towards said frame, and or orcing frame. 1 le laced be. tweenthedoor# ameand the edgle ofthe have been' .sho
