UNITED STATES PATENT OFFICE.

WILLIAM G. N ORRIS, OF SEATTLE, WASHINGTON.

SAFE 0R VAULT.

To all whom it may concern:

Be it known that I, WILLIAM G. NoRRIs, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Safes or Vaults, of which the following is a specification.

This invention relates to safes or vaults, and has particular reference to that class thereof known as burglar proof 7 safes.

The primary object of my invention is the provision of an improved structure whereby superior protection to the mechanism for locking the safe door is afforded.

With the above, and other desirable objects referred to hereinafter, in view, the invention resides in the construction combination, and arrangement of parts as set forth in the following description and defined in the appended claim.

With reference to the accompanying drawing, wherein like reference numerals designate corresponding parts throughout: Figure l is a plan view in partial section of a safe embodying the features of my inven tion. Fig. 2 is a view in front elevation of such a safe shown in partial broken section, and Fig. 3 is a fragmentary sectional view on large scale, taken on line 3-3 of Fig. 2.

In the drawing reference numeral l designates a safe body provided in its front wall with a door opening about which extends the door jamb, as 2. The said body and jamb, in practice, constituting an integral structure formed of unmachineable metal, such, for example, as manganese steel.

Fitting in the jamb 2 is a door 3,which, as shown, is of rotary type and provided with the usual lugs, as 4c rfor engagement with similar lugs as 5, of the jamb. The door 3 is supported on a crane hinge 6 in the usual manner, and the ordinary rack and pinion provided to rotate the door in its seat.

In the solid body portion or jamb 2 I provide, at a suitable point, a chamber 7 adapted to receive a lock casing as 8. This chamber is preferably provided with a wall of machineable metal conveniently consisting of a soft metal or steel insert 9 located in position during the casing of the safe body.

Specication of Letters Patent.

Application filed April 8, 1908.

Patented May 2, 1911.

Serial No. 425,929.

lhile I have shown (see Fig. 3) the chamber 7 and casing 8 with curved upper and lower wall surfaces which are substantially semicircular in cross section they may be of a different form. I prefer, however, to curve the top and bottom surfaces of the wall and casing so that the same may be readily ground or finished to obtain a spaceless, metal-to-metal contact between the lockcasing and wall of the chamber.

Mounted in casing 8 is a lock bolt 9 which is adapted for engagement with the door 3 to lock the same from rotation after the door has been properly seated in its jamb. This lock bolt is connected in any well known manner for operation by a rotatable spindle or arbor 10 fitting rotatably in an aperture as 11, provided in the body portion or jamb 2 during the casting thereof and subsequently ground to offer a smooth bearing for the spindle.

The aperture or bearing 11 is preferably formed cylindrical in contradistinction to the well known tapering form common in safe doors, and I preferably abut the inner end of spindle 10 against the wall of chamber 7. It is therefore apparent that should a blow be delivered against the spindle tending to drive it inwardly the impact would be absorbed by the body of the safe without obtaining a Wedging effect, such for example, as would result from a blow delivered to a tapering spindle. Furthermore, after the spindle bearing is once lubricated the oil will have less chance to work out' and permit the spindle to bind in the bearing.

As the body portion or jamb 2 constitutes an integral structure of comparatively large bulk it will be obvious that it oers superior resisting qualities against burglarious attack and therefore affords superior protection to the lock.

Having thus described my invention, what I claim as new, and desire to secure by Letters .Patent of the United States of America, 1s:

A safe or vault comprising a body and a door, said body having about its door opening an integral, cast body portion or amb of unmachineable metal having a recessed insert of soft metal located in its jamb surface during the casting of such jamb, and an Signed at Seattle, Washington this 31st aperture extending from said recess to the day of March 1908. exterior of said jamb, a lock casing supported in the recess of said insert, and an WILLIAM G NORRIS' operating spindle extending through said Witnesses:

aperture and said lock casing and abutting ARLITA ADAMS,

said insert. EDWARD W. CRESSMAN.
