Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed February 27, 1906. Serial No. 303,255.

To all whom it may concern:

Be it known that I, JACOB BAUM, a citizen of the United-States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Safes, of which the following is a specification.

My invention relates to improvements in the fronts of safes.

The object of my invention is to produce stronger, more durable and neater safe fronts more economically than heretofore constructed and to render the door plates inter changeable.

.My invention consists in an angle plate for safe fronts formed from a single piece of sheet steel and having a flat sheet sheared therefrom and hinged therein to form the door-plate, or separated into two parts and each part hinged thereto to form plates for double doors whereby an aecurateand perfeet fit of the door or doors issecured and economy in material, labor and machinery is effected.

My invention also consists in the parts and in the peculiar construction, combination and arrangement of parts as fully set forth and claimed.

In the drawings which serve to illustrate my invention: Figure 1 is a plan view showing aflat plate ofsteel. Fig. 2 is a perspective View of the same after it has been flanged to form an angle plate having curved corners, to form the. front or back of a safe. Fig. 3 is a perspective view showing the reverse side of an angle plate similar to the one illustrated in Fig. 2 with the central part sheared therefrom, forming the door plate and front frame respectively. Fig. 4- .is a perspective View showing the door plate divided to form a double door. Fig. 5 is a perspective view showing the back fastened in position upon the outer shell and the front frame ready to be adjusted in position upon same and also the frame casting which receives the door ready to be fastened tot-he front frame. Fig. 6 is a perspective View showing the door plate ready to be applied to the rear part of the door. Fig. 7 is a vertical section of the back of the safe. Fig. 8 is a vertical section of the front frame of the safe. Fig. 9 is a perspective view showing the parts comprising my invention applied in osition upon the safe.

'lhe article of manufacture comprising my invention is preferably constructed substanfront frame for which it was intended so that lute uniformity in size of door plate, door tially as follows: An angle'plate 1 formedfrom a single piece of sheet steel, as shown in Fig. 1, comprising a body 2 and flange 3 and made to conform to the shape shown in Fig. 2 with exterior corners 4 and 5 respectively each slightly curved to form a nearly sharp angle and interior corners 6 and 7 respectively each slightly curved to form a nearly sharp angle is provided to form the back of 6 the safe as shown in Figs. 2 and 7 respectively. V The door plate 8 and front frame 9, respectively, are formed by shearing the center from a part like that shown in Fig. in the manner illustratedv in Fig. 3 and said 7 parts are applied to the inner door frame 10 and rear part 11 of the door respectively in the manner shown in Figs. 5 and 6 respec tively.

Heretofore in the manufacture of safes, the front frame and door plate were constructed from different pieces of metal and independently of each other. The opening for the door plate in each front frame varied somewhat from the door plate opening in every other frame, and the door plate being constructed separately from the front frame and from different metal than the front frame, varied in size from the opening in the 8 there would be some difference in the size of each door opening to receive the door plate, thus requiring each door plate to be made larger than needed and trimmed down to the proper size to make it fit perfectly in the frontframe. This manner of constructing the safe fronts was unsatisfactory because of the great expense in constructing them due to loss of material and greater skill in work manship required as well as producing door plates which were not interchangeable.

By constructing the frontframe and door from a single piecev of sheet steel formed in the shape of an angle plate and having the central part sheared therefrom to form the door plate 8 and front frame 9 respectively I am enabled to utilize all of the sheet metal plate from which the front frame and door respectively are formed, and to secure absoopening and door frame in the front of every safe, thus rendering both the front frames and door plates interchangeable. I am also by this means enabled to utilize all of the sheet metal late from which said front frame and door p ate. are: constructed, by cutting the door plate 8 from the angle plate 1 by means I of the safe to replace doors which have been BEST AVE-iii QQFY,

' of a shearing die thereby obtaining an absofront frame, or hammering the door plate to increase its size to produce an accurate fit therein, thus effectlng a great saving 1n Work and materlal and enhancing its 'deslgn 1n contour and symmetry.

The door plate 8 1s riveted to the rear art 11 of the doorcarrying the locking mecl fanism and is pivotally secured to the front frame by-means of suitable hinges 13 riveted to said door plate 8 and front frame 9 respectively. I Y i When a double door is desired the door plate 8 may be cut in two as shown in Fig. 4 and hinged-within. the frame between the curved outer corners 12 of each plate thus divided.

An important advantage derived from this construction is in the ability of the owner manufacturer for damaged by burglars orotherwise Without the expense of shipping the entire safe to the that purpose, all that is necessary being to inform the manufacturer of the size of the door required and from this information the manufacturer can duplicate it and the owner can have it easily and quickly. placed in position upon his safe and obtain a perfect fit Without modifying or changing its form, shape or size in the slightest degree. Each door plate for safes of the same size is exactly the same in dimensions and exactly the same in dimensions of every door opening of the front frame from which they 40 are taken and are accordingly interchangeable. v a

I claim: i 5551 In a safe, a flanged front plate form'ed'jfrom a single piece of sheet metaland having a plate sheared therefrom and hinged thereon to form a door, substantially as described and for the purposes set forth.
