A still further advantage isfobtajined by j providing rollers'upon which the-bolts are guided, thereby reducing to a minimumthe frictionbetweenthe socket wa-lls'f and the or shot into place in the sockets.

Astill further advantage is obtained in that the difiiculties accompanying broaching processes which. are usually necessary for providing a proper clearance" in the bolt bolt surfaces as the latter are, drawn out-of sockets for the practical insertion of bolts and for the proper contactofthe usualcylindrical surfaces of the bolts andflsockets;

are wholly avoidedin the form of t-device constituting the subject "matter of this in vention by merely making the socket and the boltof exactly the same'shape, 'thelatter onlybeing smaller-than the. former in order that it maybe inserted therein.

Inasmuch as'the structure of the "elevator forfthe lowering form of 'elevator,' many' of which' are at when the. door'l" is openmaybe coveredby afoot bridge or'filled with a spacer, which may be located in'placeby handas desired.

The door 1, as shown; is supported upon a crane 9 pivoteduponhinged members'fi by i the pins. 8 and further by means [of the {hinged straps 7 fixed to, said doorfand'p'ivoted upon the crane'by meansof the pins 8.

lis similarto those in use'on vault doors in I general but with the "exception that. fewer I, {compressor b'arsare necessary on account of the reduced width and'perimeter of the oval form of door. Far less power isrequired to force such door to a'tight position. 11'

a. After the door ha's been properlyfseated under the action of the co npressor cams the locking of thedooris accomplished by forcing a series {of bolts llthrough thesockjets of the'loolt ring 15 against a locking ring 13.

4 For this purpose the rear ofthe doorisjprovided with a ring 15' of elliptical for-melooated adjacent to theperiphery of the door.

This ringiis .provided'with a plurality of sockets of a A preferablytriangular. form I T withinpwhich' the: bolts 14 are adapted" to fit and move; Tothe bolts llare connected threaded rods 25, which arehprov'ided at an ,end thereof 1 with lniter gears 25f mesh with: miter gears '31- secured to-the main driving shaft era-n01 at the other end thereof with a threaded portion for connection with .an adjusted sleeve'22 which is iii-connection with the threaded portion 23 of tha holt14.

After an adjustment is" made; a locking pin may be insertedin aboring that l rod 25 forthe purposefof permanently locle ing the parts in their adjusted position, fThe adjusting sleeve 22 may also he provided with a knurled rim 24; by which the adjust ingsleeve may be operated during its adj ust-' fling operation."

however slight the-clearance may be it is tendency; to reduce the resisting surface 'to nevertheless suflicient to divert the holtfrom Q 7 its parallelrelationwith the socket wall in its lockedposition and; therefore,:has a the smallest possible area The triangular bolt, however, takes advantage of-the clear ance space'to releaseitself of all friction the the purpose of permitting the .boltto readilyenter into and withdraw. from the-socket.

instant it is moved, in unlockingoperation, the weight of the bolt being transferred immediately tofth'e friction rollers." The adijustable wedge or inclined means at therear end of the bolt maintains the" bolt parallel with the vresistin surfaces of, the socket with the advantage 0 an equally distributed con- I tact of the resisting surfaces throughoutthe lengthof the bolt rather than at a particular point onthe bolt. V 7 p I It will be noted that the sockets are made of exactly the, same form as the bolt but of slightly larger dimension which latter is" for The difference in the cross sectional. area of the socket and thebolt, as clearly shown in .Fig. 9, provides aclearance space 16 forthe purpose given above, which clearance space is shown, when'the bolt isin locked position, be1owthesame,as viewed in Fig. 9; .When the bolt is withdrawn it will'be caused, by

reason of the inclinedsurfaces 17 and 18 "as Welles surfaces19 and 20, to move later-ally ,overthe roller 27 and at the same time longitudinallyover said'roller. In this operation the inclined surfaces of the bolt will. part from the corresponding surfaces of the sockets-and produce new' clearance spaces v 14 ,14 "AS the bolts-restupon therollers 27 there is'little tendency of-the face L14 of the bolt 14 contacting with the .face 14 of the socket In case they should contact the 1 sameis but slightandthe area'ofjthe contact is far less tha'nthearea of the surfaces at 14 and 14 andthe friction is"accordingly reduced. r

Referringnow more particularly to, Figs. land 2 to6, inclusive, .which disclose the operating means formoving the bolts, a 'singlehand wheel 32-has been provided forthe purpose of performing the various functions" mentioned. "The handwheel is secured to a shaft 33 rotatably andslidably supported in the housing secured to, the front of, the'door 1. r The inner end ofthe' shaft has a bearing 7 40 which is adapted to rotate, as well as slide longitudinally, in a bearing socket-Q41 of the coupling sleeve 42.

shown as secured to the coupling. sleeve 42 in a suitable manner, as bymeans of a pin.

The shaft leads toa gear 4e secured thereto atthe end thereof, which gear meshes with the gears 45 mounted upon theendof the horizontal rods and also meshes with-two of the gears 31. mounted at various intervals uponthe vertical shaft 31. The remaining gears, 31 in turn engage with the r gears 25 mounted uponthe ends of inclined and vertical. shafts 25.

Upon the rear offlthe door is mounted a set of time locks 29 "of anyjsuitableform. Theselocksmay be connected to suitable cams 30 mounted upon the main shaft 31 for the purpose of locking and releasing the same 'at p'redetermined times.

Fig. 12 shows, a section taken on the same horizontal planeas that of Figlll of an oval or elliptical form of dooriwherein the same thickness ofmaterial i'sutilizedi' Itnis material used in the frame thereof, the oval or elliptical form of door would be considerably stronger than the circular (10101:; Fig. 1 a it 1 13 shows a section similarto thatxofYFig. Figs. 2,3,

Itis evident thatwiththe "u ed the ovaljorelliptical fornrf of door, that-the 1 space represented by the crescent shaped area on the opposite sides fof said: door, shown in Fig. 1 is economized in door mar terial and that the vault space'on' each side offtheoval or elliptical door of the vault is economized similarlyb- This feaim'rehas? been described'hereinbefore. V Figs.'15 and 16 are. more or lessidiagrammatic views showing the section of the tri; angular bolt and the socket in" which the bolt is adapted to move-as well'asthe conventionaliform "of cylindrical bolt used in 1 the socketof the conventional doer.;'-=- These figures clearly ShOWj that when the triangu= lar form ofxbolt is used and the same has been moved into locking'po'sition, the contacting surfaces, upon two sides of this boltare in complete contact throughout thesurfaces with the twocorr'esponding, faces of the socket. Therefore, the line "repre sents a projected line or surface of strength,

said line being equal";to'substantially the' length of thebase ofthe"trianglefrepresenfluing a section of this bolt. Thisline, it will be seen, is considerablylonger than the di-' ameter of a circlehaving the-same area of-' cross section as the triangular-bolt. FigQlG showsthe relative position of the cylindrical boltin' the socket Walls within 'which the same operates. In this case,- when the bolt is presented in the socket, on theory, but one line of contact occurs between said bolt andsaidl socketjwall, but inpractice the line a4) 'is' 'shown to indicate the projectedlengthbf thesurface of contact between said rod a and socket. 'lhe jbolt of V cylindrical form cannot c'onta'ct; the 'wa1ls of the cylindricalgsocket with equal-stress. throughout one-halflof itssurfacej and the contact betweenthe surfaces of {the bolt and socket could not be" represented by the projected line equal to the length-of the diam; eter of-the bolt. Consequently, Figs. 15'and 16show a comparison of the strength of the two forms of locking means.

a 1 willalso benoted that; aside as the n i s reng h in: th l s in t e us f the triangular form, there is alsoa similar gain in the strength of thebolt ring by reasonof the amount and the form of the. materialin the portion thereof resisting the lateral action of Qthebolt, Figs, 15 and l6, therefore, also serve the purpose to comparatively represent by the lined areasshown therein, therelativej strengths of the portions of the ring referred to.
