IMPROVEMENT IN SAFE-DOORS.

Specification forming pari of Letters Pat-cnt No. 116,686, dated July 4, 1871.

To all whom t may concern:

Beit known that I, DEsTAING S. Cov-ERT, of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Operating SaieDoors; and I di) hereby declare the following to be a full, clear,

' a-nd exact description thereof, sufii cient to enable others skilled in the art to make and use my invention, reference being had to the accompanying drawing which makes part of this specification, and in which- Figure l is a front elevation of part of a safe and door with my improvement attached; and Figs. 2 and 3 are sectional plan views, the line of section being in a. u., Figl, and the door being shown in different positions.

Like letters of reerence indicati-1. like parts in the several iigures.

My invention relates to that class of safes that is provided on its inner ends with projections fitting into grooves in the bed of the door, and which must be moved out of its bed at right angles to the front of the safe before being swung on its hin ges, and it consists in making the pivot of that leaf of the hinge which is attached to the door movable at right angles to the line of the leaf by sliding on a square piece projecting at right angles from that leaf ofthe hinge which is attached to the safe, as hereinafter more fully described.

A in the drawing may represent that part of the front of a safe to which the doorB is hinged. This door is provided at its inner ends with projectionsb b, which lit int'o corresponding recesses a a formed in the bed ofthe door in the safe. C is the leaf of the hinge attached to the door of the safe, and is provided with a hea-d or projection, c, which fits over the pintle d, which slides on a projection, e, formed on the leaf E of the hinge, which is secured to the safe, and which projection extends out from the leaf at right angles to the face of the same.. The limit of the motion ofthe pintle d sliding on the projection e is formed by a pin, f, passing through the projection e at its outer' end. The shape of the projection is immaterial. It may be round, square, or of any other shape. In the drawing I have shown it square, the lower enlarged part of the pintle seizing over the projection so as to freely slide on the same. On the upper portion of the enlarged part of the pintle (I I secure a plate or disk, g, having at one point of its circumference a portion cut out, into which cut-out space lits the end ot' a lever, D, pivoted at lL on a suitable rojection, t', secured on the safe in such a manner that when the lever D is moved inwardly or toward the safe the plates or disks g on the pintles d are forced outwardly o1' away from the face, causing the pintle d carrying the leaf C of the hinge to slide outwardly on projection c, thus removing the door B out of its bed at right angles to the front of thc sa fe. As soon as the outward face of the enlarged part of the pintlc abuts against pin f, the projections I) have been moved out of their respective recesses, and the door is now free to be swung, its pivots being the pintles d, now Vsituated on the out fard end of projection c. By moving the lever D outwardly the disks g and leaf C of the hinge attached to the door are forced inward in a straight line. The lever D operate both the upper and lower hinges, and where more than two hixlges are used they all can be operated by the same lever D, as will readily be understood. The two positions of lever l) are clearly shown in Figs. 2 and 3 .of the drawi n It will, of course, be seen that the disks g might be provided with cogteeth on a certain portion of their circumierences, into which the teeth of a cog-segment on the inner end of lever D seizes, a-nd that the operation of the lever would then be preeisely'the same. I therefore do not confine myself to the exact construction ofthe parts by which this lever operation is performed, as they may be varied.

Having thus described my invention, I claim- The safe-hinge, consisting of the lea-f C provided with head c, which lits over pintle d, which latter slides on a projection, e, formed on leaf E, and lever D, all arranged to ope ate substantiall y as described.

The above specilication of my improvedV mode of operating safe-doors signed this 18th dayT of February, 1871. y
