in its sides arranged so that persons in the enclosure can gain access to the outside ladder. In the stories above the ground floor, the opening are preferably window openings placed a distance above the floors, and are provided with closures 7, which are preferably inthe nature of outwardly opening, double-leaved frames 8 guarded by strong open-Work 9. The lower-most compartment has a door 10 similarly designed. It will beunderstood, however, that the form of these closures may be varied, provided, ho'wever, that they constitute sufficiently strong barriers to make it difficult for a burglar to break in, and also that the openings or the closures, or both, be so arranged and designed, that small children cannot open them on the upper floors, or get through them.

Each of these closures is provided on the inside with a suitable catch or latch 11 adapted to bereadily opened on the inside, but not from the outside, these latches being protected by plates 12 set into the closures, and also cups and flanges 13 on the inner sides of the plates to prevent the latches being released by inserting an arm or an instrument through the openwork and reaching around behind the plate.

The enclosures of the fire-escape have solid floors 14:; and the floors above the groundiloor enclosure are provided with trap-door openings, which are closed by trap-doors 15. vIn order to provide ample exit from each enclosure to the enclosure beneath, two trap-doors are arranged in each of these floors, other, preferably at diagonally opposite corners, and the trap-doors in successive floors are disposed in staggered relation, so that the formation of wells is avoided, there being solid floor beneath eachopening in "the floor above. These trap-doors are locked by latches 16 operatable from above but not from below, so that they can be readily i ladders from being.

it being necessary either to drop the dis tance from the foot of the ladder, or else to swing over onto the broad ladders formed 1 J. 1.. by the iClJdCGIlb barred sides of the enclosures.

The trap=doors are to be painted red so that they can not oe-overlooked, and they are recessed at their tree edges to permit the ladders 17 to extend through the openings.

The top enclosure has a trap-door 18 through its top, to enable persons in this enclosure to escape onto the roof, if this should be more convenient, or it escape should be cut oil below, This door a catch 19 which can be opened iroin below, but not from above.

The fireescape structure has suitable corner supports 20, and suitable intermediate verticals 21 uniting the bars and contributing to the support.

An important function of the grille work is to constitute a babyguard, preventing all possibility of babies'and small children left to play felling oil-the porches. The bars are, thenefore placed sufiioiently close to gether to keep a child from getting through, this close spacing being entirely suitable, and indeed adyantageous, in respect to the use of the structure as a safe ladder \Vhat I claim as new is:

A fire-escape comprising series of enclosures on the outside of a building having internal passageways permitting persons to passrdownward from one enclosure to an other, and trap-doors for said passageways with latches adapted to be readily opened.
