SPECIFICATION formngkpart of Letters Patent No. '7018,041, dated September 2, 1902.

Application filed March l1, 1902. Serial No. 97,688. (No model.) i

T all whom, it 1v1/tty concern: l

Be it known that I, HENRY DEMING H1B- BARD,a citizen of the United States, residing in Plaineld, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Safe or Vault Doors, of which the following is a specification.

This invention relates to safe or vault doors, the object of the invention being to provide 1o an improved door constructed to aord protection to the boltwork against electrical attacks and also to more completely protect the interior of the safe against the action of fire, while at the same timeinsuring a firmer wed g- '15 ing of the door in its jamb.

It is sometimes desirable to provide the body of a safe or vault door with increased thickness in cross-seotionwithout increasing the thickness of the casting, whereby addi- 2o tional security and protection are afforded to the boltwork and to the interior of the safe or vault, and for this and other purposes I have provided an improved organization of` door in which the means for reinforcing the 2 5 door cooperates with the boltwork in such manner that while the latter assists in maintaining the reinforcing means in position the reinforcing means in turn is effective to cause the bolts more tightly to wedge the `door in 3o the doorway.

In the drawings accompanying and'form-n ing part of thisV specification, Figure l isa perspective view of the rear side of4 a door with a part thereof broken away more clearly 1 to show the structure. l Fig. 2 is a cross-sectional view of such door, and Fig. 3 is a perispective view of one of the wedges for wedging one of the parts in position.

This improved door comprises a body or 4o outer plate 2, having rigid or formed integral therewith arearwardly-extending flange 3, provided with the usual offset or step 4 and openings 5 for the passage of the bolts. This door so far as described'may be similar in construction to those shown, and described in my prior patents and is usually formed of unmachinable metal-such, for instance, as manganese steel, which, as is well known, it is not practicable to drill or cut.

5o Located on the interior of the door between the boltwork and the body of such door is a reinforcing member or filling-plate 6, preferably corresponding in shape to thatof the door. This plate is shown connected or bolted centrally thereof to the door by a suitable bolt 7, which extends into an insert 8, of soft metal, cast in the door. It is shown maintained in position at its periphery by the wedging thereofand for this purpose I prefer to use a plurality of wedges 9, which when the 6o door is of circular formation will form a ringshaped wedge. Heretofore the body of the door has been provided with surfaces for supf porting the bolts; but as the body was ymade of manganese steel considerable time and -laborwere necessary to grind such surfaces to provide proper bearings for these bolts. In the present instancethese bearing-surfaces 1 are carried by the plate 6, which may be of ordinary steel, and therefore such bearing- 7o 'surfaces may be readily formed in any wellknown manner. This plate 6 is also provided with a rearwardly-extending centrally-located boss 12 to engage the inner ends of the bolts when they are protracted, whereby the retraction of the bolts is not possible except by the proper operation thereof. These bolts :may be actuated in any suitable manner-as, for instance, by suitable gearing, one member 13 of which is pivoted to the rear ends of 8o the bolts and is carried by a suitable stud of a back plate l2', secured'tothe iiange of the door. Y

The door is provided with bearing-surfaces 10 to engage similar surfaces l0' of the ll- 85 ing-plate, whereby strains transmitted to the filling plate are received directly by the door. This plate forms, with the door-body, a chamber 15, in which is placed a filling of suitable non-conducting material, such as 9o cement and sand, which not only assists in rendering the safe or vault more nearlyV fireproof, but also assists inresisting electrical attacks, since should thebody ofthe door be penetrated by a burglar workingunder extremely favorable` circumstances by using the electrical arc, which has not as yet, so far as I am aware, been successfully tried in a burglarious manner, it would still be necessary to dispose of a substantialportion of the roo non-conducting material before he could proceed further, all of which would require so much time that it could not be done within the time which a burglar would ordinarily have to devote to this purpose. By the provision of this reinforcing-plate 6 and also of the iilling material the door is rendered very massive, and this without the necessity of casting such door in one thick piece, which could not be so readily subjected to the subsequent heat treatment, so that the shocks of an explosion will be distributed over a much larger area and mass of metal and material, and consequently be'of less effect to 'disturb the bolt mechanism or jar the actuating means ont of its properoperating position, and so interfere with the proper operation of the door. In the present organization it will also be seen that the bolts resting on the plate 6 tend to hold such plate in position when such bolts are lin their protracted positions, since the strain thereof will be received by the plate-that is to say, the load being at the points a and the fulcrum at the points b the power will be ap-l plied at the points c to the plate 6, and so assist in holding it in intimate relation with the bearing-surface of the door-body, the bolts forcing the plate toward the body of the door while simultaneously forcing the door inwardly into the jamb, this resulting-,in causing the bolts to more tightly wedge the door in its doorway. From this it will be seen that while the plate 6 receives the strain of the bolts it also constitutes means other forms of which could -be used for resisting the movement of the bolts, and so cause the bolt-heads during their rotatable or swinging movement to move with considerable grinding action over the bolt-surfaces of the safe or vault body, thereby insuring a most powp erful binding of the bolts upon such body-surfaces, and this with a minimum amount of power applied to the bolt-actuating means.

At the point where the lock-spindle projects through the door suitable apertured bearings or surfaces are provided, one on the fillingplate and the other on the door-body, the ends of which engage each other, and so prevent sand from coming in contact with the spindle.

Having described my invention, I claim- 1. A safe or vault door comprising a body having a rearwardly-extending iiange integral therewith provided With bolt-openings for the passage of bolts; bolt mechanism carried by such door; and a filling-plate located vbetween the bolt mechanism and said body and receiving the strain of said bolts when in their protracted positions, whereby such bolts assist in maintaining said plate in position.
