i Application filed March 24, 19,05. Serial No, 251,833.

To all whom, it muy concern:

Be it known. that I, lJOSEPH ALBERT BRECKON, manufacturer, ofthe city of Toe, i ronto, in the county of York, in the Province '5 of Ontario, Canada, have invented certain new and useful Improvements in Fire-Es capes, of which the following is the specification.,1.

My invention relates to improvements in ro4 fire-escapes;and 'theobject of the invention is to devise a simple, strong,` durable, and

. safe escape which may be readilyicontrolled l when ascending or descending; and it consists, essentially, ofanelevatorcar or cage,

.15 suitable U-shaped guideways securedto the side of the building andin which the same is guided as it ascends4 ordescends,'ropes attached to the cage at each side and passing overpulleys under vthe eaves and provided zo with counterweights verticallyT movable in tubes secured lto the sides of the building, a walking-beam secured tothe top of the cage and ropes vor chains connected to the same and passing up through pulleys underfthe z 5 eaves and down through the cage-and around a pulley at thegroundA and up tothe .bottom of the cage, and a controlling-rope controllers, vand brake, the parts being arranged and.

constructed indetail, as hereinafter more 3o particularlyexplained.

Figure 1 is a perspective-viewof 'myA irn-v proved fire-escape, the upright guideways,

pipes, and ropes being intermediately broken away.

Fig'. 3 is an enlarged detail of the controlling device.

-In the drawings like 'letters of reference in.-

- dicate corresponding parts in each figure.

A is'the cage o'r car, which is provided at.

4o the inside with the sliding door A. A2 represents bars secured tothe brackets a at the inside of the car.

A2 are preferably made-of wood and extend the partial length of the car vand fit into the two grooved guideways B, having the inner side open and facing veach other,l such grooved guideways being suitably secured to the wallfromthe eaves to the ground C C are bars secured in the 'top of the cari' 5o and projecting beyond the sides thereof.

. D D arev cords or chainsconnected'to the ends ofthe bars C C andextending over puly leys 'c,ilo'osely held on the ends of the vspinlidle `jmlrnaledy in bars- E under the eaves,

J', secured aty the side of the building andup to the bottom of 7o lpractically a link of the cord. are suitably heldin the wall under the eaves, 7 5 J being preferably supported bya brace e.

bracket L", tends.

Fig. 2 is a vertical section ofthe car.- 'the bracket M.

angle- The bars rI grooved wheels N and down into the vertical tubos F, which 5 5 extend from theeaves to the ground, the bottom of each of the cords being provided with a counterbalanceweight G, both 4of which combined. are preferably sulliciently the weightof a man therein. A His an equalizing-bar pivotallyconnected' to the center of the bars C by the brackets .h

h. The ends of the equalizing-bar have connected to them the cords or chains I, which `65 extend up over pulleys J', secured .on the spindle y', journaled in the bars E, and downwardly through the car and around pulleys ground preferably to the the car, towhich each coro' I is suitably connected. It will thus be 4seen that the cords I are practically endless cords, thecar. forming The bars E' K i's thecontrolling-cord, and L is a b rakewheelsecured on thespindle j.

`Zi s. abrake-band secured to the fend of the I through which the spindle J eX- 8o be seen bythrowing the lever down, 'so thaty 90.

thelongerdiameter is opposite the cord K,

i thatv the cord may be gripped andthe brake rp ut on, so as to stop the car at any desired height. I If it should not be desired to put on thel brake, but allow' of the carto run slowly,- 95. provide in addition the grooved wheels N N, which are held in suitable brackets n, the cord passinv through the grooves of the wheels, as in icated. yI also provide a'grooved Wheel N on the end of aleve'r n,suchgrooved xoo wheel. being located interlnediately of the ,By` pressing down upon the. handle end, O'f

lso asto regulate the speed of the'descent.

Inorder toprovide, forthe firemen getting up on the roof, Iprovide a balcony O,lo'cated a jacent to the pathof the car nearthe eaves 1 heavy to counterbalance the'weight of the car plus {6 0 y the lever the frictional grip upon the c'ord or'wire may be regulated,-

and I also priiide-aladder I?, e tending r'ornA such platformilp on to tletopof the roof.

It Will of -couse bessen that I provide an exit-doorwayin' the cen-terni; the car anda -side doorwayinl order. vtliatW-hen the car reachesth platfon O'aiieman may alight on-such Ipla-tafornn's'xo asto get 'on the roof.

From this descriptlnjitfwill be seen that I -providea veryeficlenti'ev-esca e `applicable to any buildingand ofany h What I claim asm 1. l In'a ire-escap g eig t.'
