NEW YORK, N. Y.

IMPROVEMENT IN BURGLAR-PROOF SAFES.

Specification forming partof Letters Patent No. 107,021, dated Septcniberf, 1870.

To all 'whom 'it may concern:

Be it known that I, JOHN FARREL, of the State, city, and county of New York, have invented an Improvement in the Construction of' Burglar-Proof Safes, of which the following is a specification:

This invention relates to the construction of' safes chiefiy of' wrought metal; and its object is to prevent the wedgin g apart oi' the plates or sections of metal of which the exterior is composed.

Heretof'ore it has been common to build the body of the safe of a suitable skeleton or shell of iron, and to nish the outside surface by adding on strips of metal to represent styles, of' which the said shell formed the panel, the same being the greater portion of the visible exterior. Such inode of construction is open to the objection that joints or crevices are left exposed at the corners, running longitudinally therewith, and otherwise so situated as to admit of the entrance of the wedges therein, which wedges so entered, and exerting a force between the body of' the safe and the aforesaid strips or bands, the latter would be easily forced otl', thereby materially weakening the safe, and preparing it f'or further attacks in places less dificult ot' penetration.

My improved plan of construction contemplates such an arrangement of the plates constituting the outer wall or layer of metal as will obviate all seams at the corners of the safe, and so dispose all others as to render it impracticable to enter the safe by any process of wedging open the seams; and said invention consists, essentially, in the employment of a number ot' continuous bands of metal entirely surrounding the sides, top, and bottom of the safe, in combination with solid angle frames of iron or steel, or both, to protect such bands front and rear, cover the seams formed by their junction with the body of` the safe, and from the remaining corners.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same.

.In the annexed drawing, Figure 1 represents separate parts of the safe as they appear bef'ore being put together. Fi g. 2 shows the safe as it appears when completed and ready to re- I first construct a suitable shell or skeleton,

A, and build therein with strong knee-pieces ot' welded wrought iron and steel, protecting all the corners. I then prepare a frame, B, for the back .of the safe, of heavy angle iron or steel, having all the corners mitered and solidly welded. This frame is rrnly secured to the skeleton or body A, and f'orms the corners and margin ofthe back of the saf'e. The central panel of the back is of' Franklinite or similarly hard metal, likewise bolted first to the frame B. `I next f'orm solid bands C, of iron or steel, or both, by weldin g together the ends ot' wide bars ofl suitable thickness, or in any other manner, as shown in Fig. 1. These are slipped over the outside of' the body A and shrunk thereon or driven down to the frame B. Vhen the required number otl bands is placed (I use the fewest number practicable, generally not more than two or three) I finish the front with a heavy f'raine, I), of angle-iron, corresponding to that used at the back B, with the exception of such modification as is required to fit it to receive the safe-door, so that these frames B and D completely cover and protect the seams formed at the junction of' the bands C with the body of the safe. The result is that all seams ordinarily occurrin g at the corners, as well as those adjoining the edges of any plates or bands forming any part of the exterior, are entirely obviated, the only seams exposed being those between the edges of the endless bands G and the frames B and D, where the force exerted would have no ef'` fect.

In the above invention I do not confine m yself to anyparticular construction of the body or skeleton on which the safe is built, but shall use such plans and modes as are best adapted ,to f-he carrying into effect ot' my invention.

The application to the body of' the saf'e ot' JOIIN FARREL.
