.To all whom it may concern:

Be it known that I, JOSEPH FISCHER, of Cleveland, in the county of Cuyahoga and State Improvements in Burglar-Proof Safes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to My invention relates to improvements in so-called burglar-proof safes, in which an outside plate, forming the front or face of the door, is separated some distance from the body of the door, to which ,it is secured oniy along the top and sides, leaving a chamber open atthe bottom, which4 latter when the door is closed is in open relation with a passage-way made through the bottoml of the safe and sloping downward and rearward, to the end that if explosives are inserted in the chamber of the door they will be discharged on the door of the room below the safe, where if they were exploded not much harm would be done. A continuous horizontal chamberis made near the bottom of the safe, extending along the sides and back wall thereof and opening at either end into the aforesaid sloping passageway. The chamber has largev openings presenting downward, andlocated, respectively, over the wheels or castersv of the safe, and Where theyY arc concealed and inaccessible, to the end that in case the mouth ofl the sloping passageway were closed, so that explosives could be lodged and exploded therein, the door of the safe would not be likely to be blown open, owing to the free vent had through the opening over the wheels aforesaid.

In theaccompanyiug drawings, Figure lis an elevation in section of a safe embodying my invention. Fig. 2 is a reduced plan in section on the line n, Fig. 1.

A represents thebody ofthe safe, and B the body of the door. Au outside plate, B', form` ingthc face ord'rontof the `d'oor,'is secured along the sides vand top, as shown at b. This plate stands' o some distance from the body of the door, leaving` achamber, C, that extends to the. bottom of the door. When the door is closed, 'the chamber C is in open rela.-

tion with the passage-way D, madethrough Serial No. 215.919. (No model.)

the bottom of thesafe andinclining downward and rearward, asshown. Any explosives inscrted in the chamber Cof the door would be discharged on the floor of the room under the safe. Ay continuous chamber, E, extendshorizontally along the sides and backYI of the safe -inside the walls thereof, both ends of the chamber being'in open relation with the passageway D. The chamber E at four points is counected with large openings e, that extend down through the bottom of the safe. These latter openings are located, respectively, over the wheels F, the openings being out oi' sight and quite inaccessible. W'ith such construction, if the mouth of the passageway D were closed or blocked up, so that explosives could be lodged and exploded therein, owing to the free vent through the openings e and to the limited quantity of the explosives used for such purpose, the door of the safe would not be likely to be blown open or be materially injured;

The spindle G of the knob g, by-means of which the combinations are operated, is screwed into or otherwise attached tothe head H of the spindle h. This latter spindle extends into the body of the door, and is connected directly with .lle combination-lock. The head H is made large and strong, and is. located, as shown, next to and outside of the body of the door, but rearward of the front plate, B'. Now, if a burglar should break or remove the spindle G, he would not injure the spindle h, and consequently no opening would be had into the body of the door, and by reason of the head H this inner spindle could not be driven inward as means of disarrangiug the lock.
