JOHN BARREL AND JACOB WEIMAR, OF NEW YORK, N. Y.

IMPROVEMENT IN SAFES.

Specification forming part of Letters Patent No. l0,215, dated March 29, 1870.

To all whom it may concern.:

Be it known that we, JOHN FARREL and JACOB WEIMAR, both of the city of New York, N. Y., have invented certain Improvements in Safe-Doors; and the following is a description thereof, reference being had to the annexed drawing, which forms part of this specification.

The object of this invention is to secure a more perfect junction of the door with the safe, to provide additional security against opening the door` by wedging, and also for relieving and separating the door in opening it from the sides or flanges of the door-frame, substantially as hereinafter described.

In the said drawing, Figure l is a front elevation of the door and door-frame of a safe or vault; and Fig. 2 shows the same as seen from above, part being also shown in section.

A represents the body of the safe. A is the door-frame, and B is the door. The door and frame have several anges or steps, c cl c. These anges are of varying width, c representing a width of about one inch, d a width ot' about two inches, and c about three-fourths of an inch. The advantage of this arrangement of alternate wide and narrow ilanges is apparent, for if all were of equal width on the separation of one flange from its recess all would be separated, permitting a wedge to be driven in the full extent of the width of the door, whereas in this plan the wedge would be intercepted on reaching the second flange. A further security' consists of a bead, s, so formed on the edge or side of one of the anges or steps as to project laterally into a recess made to receive it in the jamb. This also strengthens the fastening of the door, and renders it impossible of being opened, even when unlocked, without being rst released from said recess. We also form a tongue, g, on the face of one of the an ges, and a correspondin g groove in the doorframe, such groove and tongue having their sides nearly perpendicular with the face of the flange, and eX- tending entirely around the margin of the door and frame. The depth of this groove exceeds the height of the tongue, in order to provide for receiving and holding a gasket or packing, f, of india-rubber, or other elastic substance, against or into which the tongue is forced by the closing of the door. The sides of the groove being nearly perpendicular with the face of the flange, as aforesaid, any attempted movement of the door in the curved lines incident to the ordinary method of hanging such doors would cause the tongue nearest the hinges to bind in its groove, and prevent the door from opening. We therefore provide for first relieving and detaching the tongue from the groove at the back ofthe door-that is, nearest the hinges-and then it may be swung open in the usual manner. To accomplish this, we connect the upper and lower hinges G H by pivots p with levers I J, which are each iixed to a vertical rod, K, and one of said levers is extended forward to form a handle, L.

When the door is to be opened, the handle is seized and drawn outward, turning the rod K, and, simultaneously acting on the upper and lower hinges, that side of the door is thrown out, and is also set back slightly toward the hinges, relieving the front surfaces, and at the saine time withdrawing the bead s from its recess r, as seen in section in Fig. 2. The dotted lines here show the position of the door when shut. The rear side of the door having been drawn out and relieved, as indicated in full lines in said figure, it is then swung open, as with the knob M, wit-hout difculty.

Instead of the handle L, we sometimes use a handle attached directly to the rear side of the door, as at N.

We claiml. 'Ihe combination, with a anged tongued and grooved door, substantially as described, of the elastic gasket f, when applied and used in the manner specilied.

2. The combination, with atlanged door having a tongue and groove, of the vertical rod, and its levers connected with the hinges of the door, substantially as specified.

3. The bead s to the side of the flange, in combination with the recess r to receive it in the side of the `jamb, substantially as described.
