IMPROVEMENT IN DOORS AND HINGES FOR vBURGLAR-PROOF SAFES.

Specilcationforming part of Letters Patent No. 153

J nly 17, i877; applicatie Drvls To all 'whom it may concern:

Be it known that 1, PHINEAS. F. KING, of St, Louis, in the county of St. Louis and State Missouri, have invented an Improvement in Safes, Vaults, &c., ofwhich the following This invention relates .to that class of s afes and corresponding threads ou the casing, the door may bescrewed into place to close the safe; and it consists, mainly, iirst,in the combination of an independent internal-ring, having screw-threads with the casingof the safe and the screw-threaded door; and, second, in the special construction of the hinge mechanism for supporting the door, all of. -which will In the drawings, Figure 1 represents a perspective view of n iy improved safe with the the front wall of the safe; Fig. 3, a partial front elevation with the door closed; and Fig. 4, a central sectional elevation.

To enable others skilled in the art to ineke and use my invention, I will now presi` d to describe fully its construction and nia-nner of operation.

A represents the casing of the safe, yconstructed of any well-known material, and in anyy wellkn`owu manner. i

.a represents n circula-1 opening of any proper size, the face of which. consists of a' 'series of inwardly-converging steps al e, as shown.

ja represents an annular projection, and a a`.;'reces's, consequentlyl formed between the 'projection a2 and the adjacent step al, the purpose of which will be hereinafter explained.

B represents an v independent ring, which is secured arcund the'opening to the inner sur face of the safe, as shown. v I

b representsscrew-threads, formed upon the inner circumference of the ring, as shown.

0 Vrepresents the door, constructed generally in any well-known manner, but prel'era bl y formed of several independent metal disks, varying in character and hardness. This corresponds in size, of. course, with the opening; which it is designed to close, and it is pre. vided with a series oi' diverging steps, c n,

as shown. v

cl represents an annula projection c1 and the' adjacent step vc, as shown, which.projectioinand recess, it wil-l be observed, are adapted teengagefi'vitii the corresponding recess and-..projectionA on the` vcasing, as shown.

c3 representsa projecting; portion upon the inner face of the doo'r,:which is providedwith screw-threads, adaptedto engage with the screw-threads of the inner ring B, as shown.

c4 represents a shaft or spindle centrally at? tached to the door, which is supported in the relatively fixed hearings in the vertical liar d, as shown. A v crepresents a crossbar or handle,b v means 'of which the shaft c* may be revolved for the purpose of screwing'up` or nnscrewing the doel'.` 1

D l) represent'brackets projecting from the front wall of theA safe, which are provided, near their inner ends,- with'the vertical` studs Or pins d G, as Shown', l v

d1 dI represent radius-bars, iooselyrheld at their inner ends'byr the pivot studs or pintles d G, and united'a't their outer ends, by. means of a lproper socket, to vthe ends of the vertical bar d?, as shown. E

d? dJ represent radinslnirs, rigidly1 attached at their outer ends, by means el' socket-iwal'- ings, to the vertical bar d", and pivoted al'.

their inner endsto the extremities of vthe rer-l tical bar di, as shown. l v

The vertical bars l2 d* and the radins-bars di d3 constitute a frame by which the door is carried, which i'ranie is hinged fai one side to the radins-bars d4 d, these latter being' then1 selves hinged to the brackets, as shown.

141,'Fig. 2, represents a stop-piece preieclzing from the inner edge of the door, which consists of a piece of steel insertedr in place.

c .represents a corresponding stop-'piece pre- .jecting fronri-the'inner/edgc ofthe ring Il,

which isforn'ieri similarly to the piece E.

'li 'represents a bolt, which is adapted to engage, when desired, with recess, l'or the pur l pose el' locking` the door lo prevent its revointimi.

r projection, and ce a recess, consequentlyl formed between the 'adj nsting mechanism, instead ingiu the lower bracket, which is provided with a spline for holding it against rcvolu-' tion. y g represents a. nut upon the stud, whichv is interposed between the upper face of the bracket and the lower face of the radius-bar which rests upon the stud. If desired, the

of being located at this place, may be located at the lower end of bar d4.

By properly turning the nutg,I the stud may be raised to compensate for any wear or sag the door. l p The operation will be-rcadily understood from the foregoingr description.I

vThe door, when opened, maybe closed by vfirst swinging it to place and then revolving' its supporting-spindle until the stops arrest further movemeut; When in this closed positionitle,recess-'oi the' door will coincide with theflbking-bclt, so that the latter, if desired, maylle shot into place to fasten the door.

ThedOOr, it will beobserved, by means of the peculiar construction. of the supporting devices employed, maybe .caused,in entering and leaving 'the opening, to move in.. planes parallel to the face of the door, and also in. a

line at right angles to the perpendicular diam- Y eter of the opening.

The parallel movement results from the swinging movement of the radius-bars d1 d* upon their pivots, by means of which `the hinge-point of the frame carrying the door is changed, to compensate for the movement of the frame itself'.A i

The movement upon a central line, without tendency to press in a' lateral direction, results y from the fact that the radius-bars move upon opposite arcs of equal circles, so that the lateral movement relative' to the the safe, which results from the swinging of the door in the arc of one circle, is compensated for by a corresponding movement of the hinge in the arc equal area.A f 4 l By means of this peculiar construction the door may be. properly presented to the o pening and may be' caused 4tov enter the saine wit 'out tendency to jam. When'the door is closed, its face, it will be observed, lies sunk within the plane of the face of the casing, -sso that no part projects outward to' give'opportunity for the attachment of burglars tools.

The stop devices limit the movement of the door so that it is impossible to jam the threads,

no matterhovv violently it may bescrewed to place.

The trackers' DD, it willi-be observed, fur- Acenter line of bracket D, having an vandfor-the purpose set forth.

of an opposite circle of nish esten-ded bearings for the radius-bars, so

that they are not subjected to undue strain.l

This independent ring, also, in connection rwith the door, when the latter is closed, serves as afclampv to bind the plates of the casing iirmlytogether, and give increased strength tothis `portion ofthe safe.

--By the employment of the peculiar hinge devices, the door, in entering oir leaving the opening, can be made to move in planes parallel lto the face of the door, and, also, in a Y A line at right angles to the vertical diameter of in the supporting'mechanism :which carries l,

the opening.

v By .providing bearing that is tion vis simplified, and a more perfect result is obtained. f

The door being supported in a balanced psition upon a central vertical axis, it may be oscillated upon this axis to bring itinto place, if itshould'ilotrbe perfectly parallel with the face ofthe safe. y v l having'v thus fully described my invention, what I claim as new, and desire to-secure by Letters Patent, is j 1.
