SAFE-DOOR.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed. March 5, 1908. Serial No. 419,367.

To all whom it may concern: Be it known that I, DANIEL H. RIGGAN, a citizen of the United States, residing at Warrenton, in the county of Warren and State of North Carolina, have invented a new and useful Safe-Door, of which thevfollowing isa specification.

This invention relates to safes of that char acter utilizing circular doors and its object is to provide a safe door the outer surface of which is imperforate and void of all projections so that the openingof the safe by unauthorized persons is rendered more than heretofore.

A further object is to provide a circular door designed to rotate relative to the safe.

body so as to operate tumbler mechanism of.

ported in a novelmanner whereby the same 7 when released can be supported beyond and at an angle tothe safe body, said supporting means being foldable into the body during the closing of the door.

With theseand otherobjects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure .1 is a horizontal section through the safe door and apo'rtion of the safe body, the outer part of the 'door being shown in plan. Fig. 2 is a sideelevation of a portion of the door, the adjoining portions of the safe body being shown in section. Fig. 3 is a rear elevation of the outer or movable section of thedoor. .Fig. 4 is an elevation showing the outer face of the inner section of the door. y

Referring to the figures by characters. of reference, 1 designates the safe body, the same being provided with adoor opening2 circular in form. Theinnermost portion of thisZdoorZopeninglisl'preferablyltapered as ine difficult p of pivotally connected members 8 designed dicated at 3 to constitute a seat for the inner portion of the door when closed. An outer portion of the door opening is stepped annularly as indicated at 4 to form shoulders constituting abutments for the outer portion of the door. An annular groove 5 is formed within one of these steps and the outer wall 6 of the groove is provided at suitable points with slots or recesses 7 for the purpose hereinafter set forth.

Pivotally connected to the safe body and inrear of the space occupied by the door when closed is a hinge made up of a plurality to-fold together when the door is closed and 'theouter member of which is pivotally connected to one or more ears 9 extending inwardly from the inner face of the inner door :section 10. This door section is preferably cylindrical for the greater part of its length,

its inner portion, however, being tapered as at 11 so as to fit snugly against the corre sponding tapered or reduced portion 3 of the door openin 2. This section 10 contains suitable tum ler'mechanism 12 which may be of the ordinary or any preferred construction and is designed to actuate bolts 13 which are slidably mounted within section 10 forengagement with sockets 14 located in the wall of the dooropening. The outer face of sectlon 10 is provided fwith a circular groove 15 concentric with the center thereof, the inner portion of said groove being extendedlaterally as at 16 so that. the groove'is substantiallyT-shaped in cross section. At desired intervals, referably diametrically oppositepoints, t e slot 7 15 is enlarged transversely as indicated at 17.

These enlargementsare designed to receive T-shaped retaining lugs 18 extending from the inner face of the circular outer door section 19. This section fits snugly against the section 10 and the spindle 20, which actuatestumblers 12 and is revolubly mounted within section 10, is secured to the middle portion of thissection 19 preferably by ro- ,v1dingitwith a winged or an ular end he d in a recess in secti0n19 by a ling 19 of soft metal so that by rotating section 19 the spindle will be operated to actuate the tumblers. ,This section 19 is stepped annularly so asto fit snugly against the shoulders within the stepped portion 4 of the door opening and exten ng radially from the section 19 are retaining and locking studs or rojections 21 preferably carrying antiriction rollers 22 and designed, when the door is moved into closed position, to pass through the recesses or slots 7 so as tobecome seated within the annular groove 5. Section 19 is preferably so constructed that as soon as projections 21 have been insertedthrough the recesses 7 the door will turn automatically for a short distance, this turning operation being produced either by adding Weight to the door at one side of its center or by removing metal therefrom, as has been indicated at 23 in Figs. 1 and 3. As the spindle 20 is secured at one end to section 19 and at its other end to the tumbler mechanism 12 which is held against removal from the section 10, said spindle will act to securely hold the two sections 10 and 19 together and prevent them from becoming separated when the safe is opened.

Suitable graduations and numbers may be placed upon the outer face of section 19 close to its periphery and these numbers and graduations can either be formed in or upon the door sections or the part provided with said numbers and graduations can be removed therefrom and foldable so as to be conveniently carried.

When it is desired to open the door which has been described, the hands of the operator are placed flat against the outer surface of the sections 19 and byturning them said sections will move therewith, the projections 18 traveling in a circle and within the groove 15. Section 10 does not rotate, it being held against rotation by the members 8. It will be apparent therefore that section 19 will operate the spindle 20 and by turning said section 19 backward and forward in the same manner as the knob of an ordinary combination lock is turned, the tumblers 12 can be shifted so as to ultimately retract the bolts 13 from the sockets 1 1. As this bolt actuating mechanism constitutes no part of the present invention it has not been disclosed in detail. After the bolts have been retracted section 19 is turned until the studs 21 register with the recesses 7 whereupon the door can be opened outwardly. The members 8 permit the door to be moved outward and to be swung relative to the body of the safe. When it is desired to close the safe the door is pushed into the opening 2 thus causing the hinges 8 to fold into the safe. The studs 21 are of course positioned so as to move through the recesses 7 and into groove 5. As soon as the door has been seated in this manner the section 19 is turned in either direction so as to cause the bolts 13 to be projected into sockets 14. This partial rotation of the section 19 can be performed by the operator, although it is not necessary as the door section 19 will automatically partly rotate as soon as released because one-half thereof is heavier than the other as heretofore eX- plained so as to promptly move the studs 21 out of register with recesses 7. It is to be understood that friction between the sections 10 and 19 can be reduced in any preferred manner as by interposing balls or rollers between the bearing faces of the parts. Such a construction however, is so common that illustration thereof is not deemed necessary. It is of course to be understood that the sections 10 and 19 can be readily assembled by inserting the projections 18 into the enlarged portions 17 of groove 15, after which section 19 can be partly rotated relative to the section 10 and the two parts thus securely held together. During the manipulation of the tumblers 12 in the manner hereinbefore set forth the spindle 20 will of course prevent separation of the two sections 10 and 19 whenever the projections 18 mow into register with the enlarged portions 17 of the groove 15.

What is claimed is:
