IMPROVEMENTJN PER'lVIUTATIiON FQRSAFEDOORS,

Specification forming part of Letters Patent no. $4.167, dated June 3,1815; application filed November 5, 1874.

To all whom it may concern Be it known that I, HENRY GRoss, of Gincinnati, Hamilton county, State of Ohio,-have invented certain new and useful Improvements in Safe-Receptacles for Valuables, of which the following is a specification:

The main object of my invention is to construct the door so that it shall be as invulnerable as any other part of the safe; and consists, for this purpose, of a peculiar construction of said door, whereby it will, when moving in revolutions or parts of revolutions, operate the bolt-work, lock, or other fastening devices.

My invention further consists of the combination of devices comprising revolving door, radiating bolt-work and crank-wheel, lockdog or an gle-bar, drive-wheel, and tumblers of a stationary look, all operating in the simplest manner to make a strong and efficient lock-up.

Figure 1 is a sectional perspective view of my invention, showing lock and door swung back, with the bolt-frame, &c., broken in section. Fig. 2 is an elevation of the bearingdial handle and a portion of the hinge of the door. Fig. 3 is a transverse section through perpendicular diameter of door. Fig. 4 shows a modified form of bolt-work. Fig. 5 is an elevation of drive and crank wheels, which respectively operate lock and bolt-work.

A is the front wall of a safe, composed of three layers of iron and one of steel, all stepped off at the jamb, as shown, to coincide with a correspondingly-stepped door, B. The jamb is perfectly circular to admit of the revolving, when in place, of said door B, which is also circular. The door has formed upon its face a stud, b, which rests in a bearing, 0, of a swiveling upright, 0, attached to the jawed hinge 0. Upon this bearing the door hangs, and revolves when operated by handle D, attached to the end of stud b. There is also secured to this handle D a dial, E, for registerin g the revolutions and parts of revolutions of the door B while passing a given point, 0, on the upright c. As shown in Fig. 3, the door B has no arbor, spindle, or holes for them through it, and is consequently constructed and hung as shown, to answer the purposes of such discarded means for operating the lock and bolt-work of the safe. These aforesaid arbors or spindles have been discarded because requiring, as they all do, holes through the door, which they cannot close as firmly as the plates of the door itself. F is the boltframe, being a circular ring of metal, secured to the inner surface of the door in asuspended position by. means of screws and thimbles f.

Between it and the door I introduce a system of flat bolt-work, consisting of a circular piece of metal, same size or smaller than the boltframe, cut into sections G, of halves, quarter's, or any desirable size and number, and secured a by and sliding upon the thimbled screws f by means of radially or otherwise cut slots g. To operate these bolts uniformly and convenientlyI secure loosely upon the stud b a crank-wheel, H, having crank-pins h, to engage directly in cross-slots g in the bolts, or to crank-arms g, as shown by dotted lines, Fig. 4. In either case any change in the relative'positions of door B and. crank-wheel H will operate the bolts in or out radially from the center, Fig. 4 showing them out or in a locked position, and Fig. 1 closed or inside the frame F. The crank-wheel H is formed with a segmental recess, h, on its outer edge, by which it is operated, one of its boundaries, 1, being radial to the circumference, and the other, 2, tangential. This wheel is surrounded by a rim of metal, N, attached to the boltframe F, and formed with a notch, n, on its upper side, which notch is the only means of perpendicular access to said recess 71/, side access being had along its full length. Secured fixedly to the stud b is a drive-wheel, I, having a projection, 2', to engage with or act upon a similar projection upon the first tumbler of a lock, J, hung independent of the door B upon hinge j, attached to the inner side of wall A. The lock consists of the frame K, fitted with stud l0, tumblers L of any desired pattern to rest upon said stud, and a dog or anglebar, M, to form a connection between the action of said tumblers and the crank-wheel H of the bolts G. When the safe is in a locked condition, the lock J hangs fixedly parallel with the wall A, the notches of tumblers L out of line, and the dog M resting upon the rim N of the bolt-frame F. At the same time the bolts G are thrown out, as shown in Figs. 1 and 4, or Figs. 3 and 5, in dotted lines, and secure the door perfectly againstentrance to ,the safe. Now, tomnlock' the it safe; modem is revolved; (carryin-g wit-b it the bolt-work,) to set by the dial E, through the action of drive-wheel I z, the combination necessary to bring the notches of the tumblers L into line directly beneath1dog;M-.i. When q the last tumbler is bron ght into line in the usual manner of reverse turning,-the motion of the doorw is-reversed until-v themotch-iaofi the.

rim N passes over the recess h and under the dog M, when, as its support is taken away,

the dog drops intortheirecessshhandiVnotehess of tumblers L, and by continuing the renolu-z tion of the door the stationary dog Mstops the motion of the revolving crank -wheel H by-pressingagainst'end 1, and changes the relative: positions of said wheel 11 and;

door B, the results of which, as before said, andas are obvious, being an operation closing or drawing in the bolts G. The door inthis condition is easily swung open. Now,-

it the door, after being closed, be revolved in the'opposite direction from that. by which it was unlocked, the dog M will arrest the progress of the crank wheel H by press? 1 ing against the tangential boundary 2 of the recess h, and as it would not retain thispogsition-unlossrguarded by rim-1N, immediately the-notch: w is reaohed, it a is forcedout leaving the notches of the tumblers L at the same timer Bynow continuing the motion ofithe door'until the drive-wheel I moves the tumblers L: suflicient "130 disarrange the notches,

the bolts G cannot again be thrown until these said notches are again brought in line, which requireslalnemoperation I claim as follows:

F 1: The door B, moving in revolutions or zboltswork of the safe, substantially in the manner and for the purpose specified.

2. The combination of the rotating door B,

bolt-work G F N, and crank-wheel H, lock dog M, drive=wheel I, and tumblers L of a stationary lock, J constructed, connected,. and operating; substantially asand. for the" In testimony ofwhich invention I hereunto setmy hand this 31st, day of October, 1874.
