rIEE-EscArE.

To all whom it mag concern:

' Be it known that I, HENRY SPERLING, acitizen of the United States, and a resident of West Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in'Fire- Escapes, of which the following isaspecification. v

This invention. relates to a fire-escape of the class described in Letters Patent No.

693533 issued to me February 18th, 1902.

The object of the present invention is to provide new and efficient means by which the raising of the ladders is facilitated; so that the operating Winches are relieved of excessive strain.

In the accompanying drawing: Figure 1 is a side elevation of my improved fireescape showing it folded; Fig. 2 a similar view showing itraised; Fig. 3 a detail of a portion of the lower post and ladders; Fig. 4 a plan with the post and ladders removed, and Fig. 5 a longitudinal section through one of the tubular lifting rods and adj oining arts. p The device comprises essentially, a platform 1 mounted upon .wheels 2 to constitute a truck. Upon platform 1 is rigidly fitted,

a base 3 to which is hinged. at 41, a lower post 5. To the upper end of-this post there is hinged at 6, an upper post 7, the hinges 4 and 6 being located respectively at the rear and front of the apparatus. Each of the posts 5 and 7 is furnished with a plurality of landings 8 which are connected by a series of rear ladders 9 and a series of extensible side ladders 10. The latter are hinged to the landings 8 and may be lowered into a horizontal position so as to rest with their free ends upon the window sills. In addi tion to the side ladders 10, the posts may also carry one or more bridges or gang-planks 11 indicated in Fig. 3. Posts 5 and 7 after being raised, may be locked in their upright position by bolts 12 and 13 respectively.

To the upper side ofthe upper post .7, longitudinally the periphery of the arch by eyes 18. The front rope 16 passes from the hinged end of the arch to a winch 19 located at the front of the truck, while the rear rope 17 passes from the free end of the arch through a guide 20 to a winch 21 located at the back of the truck. A rest 22 projecting upwardly Specification of Letters Patent. Pa tented N 30, 1915. Application filed September 18, 1915. Serial No. 51,309. I I i post'5, there isprovided, a lifting jack or post composed of a tubular member 23 that telescopes a-rod 24. .As more fully referred to in Patent 6923533, tubularmember 23 is provided with a roller 25 engaging a rail by a rope 27 leading to a winch 28. Rod

24 is hinged to post 5 at 29 and may be projected out of tube 23 by means of a rope 30 which is secured to lower end of rod 21 and p 26 and adapted to be moved along the same passes over an idler 31 to a winding drum 32 carried by tube 23.- It will be seen that by operating winch 28, the lowerend of the jack will be moved toward the back of plat form 1 during which movement it will become partly righted so as to impart an in'i-' tial lift to post '5. By then operating drum 32, rod 241 will 'be projected upward to. push said post into an upright position, in whiclr,

itisheld by locking bolt 12.

Novel means are provided for so swinging the upper post 7 that it will be carried into an approximately vertical position prior to the manipulation of winch 21, so that in this way, the power andtime required for operating the winch and the strain to which the same is subjected, are greatly reduced.

These means are as follows: Along each side of platform Lextends a track 33 engaged by a roller34 pivoted to the lower end of a tubular rod 35 To each rod is secured, a rope 36 the two ropes being wound on a pair of drums 37 carried by the common shaft 38 of awinch 39. To rods 35 are pivoted a pair of props 10, which will by gravity, tend to assume a verticalposition, and thus hold 1 i the rods in an inclined position, when moved forward along track 33. uuy ropes 41 at tached to onerof the upper platforms 8 of post. 5, and adapted to be detachably secured to the upper ends of rods 35, prevent the latter from dropping down, after having been raised to such 'a height, that props. 1O have lost their footing. f p

The two rods 35, telescope the two shanks 42 of an inverted U-shaped yoke or frame, said shanks being connected'together at their upper or protruding ends by across 19:11:43. This cross bar is furnished at its centerwith apulley 41, adapted to removably engage a I hook 45 extending forwardly from the upper end of upper post 7. In order to operate the yoke, there is secured to the inner end of each shank 4E2, a rope 16, passing ever an idler 47 of rod 35, and thence to a Winding drum 4:8 with which said rod is provided. A feather 4:9 on shank 42 that engages a corresponding groove 50 o'f rod 35, guides the yoke in a proper rectilinear direction While it being inoved. H r

After the lower post 5 has been ri'ghted the manner above described, Winch 39 o'p'- erat'ed to advance rods 35 along tracks 33', and thereby cause an initial lift to be inr parted to 'iip'per post 7; The guy ropes 41: are now attached to rods 35, and then inch druins 48 are operated to project the-yoke out or the rods, and thuscause the'sani'e impart an additional and Very substantial lift'to post T, so that the sa111e ase11111 s almost an upright position. Finally, ivir rch 21 is operated to coinpletelthe righting of the post, it being locked in its upright position by bolt 13. r H I As shown the entire structure 'be steadied by a pair'o'f ropes orcha ins 51 that are secured to one of the upper platforms of lower post 5, and are adapted-to be connected to hooks located at the forward doiners of platform 1. V

In order to lower thedeyice, boltl'i-B is released, which 19 is operated to pull r pper post 7 down, so that its hook'd5 is reenga'ged by pulley 44. Drum s are new manipulated to lower the yoke aiidtli'en Winch 39 is turned back to slacken ropes 36 and thus permit rods 35 to be, by gravity, retracted along tracks 33 so as toassunie their folded position. v A buffer 52 projecting from lower pcst 5 and adapted to npper post 7, prevents a iolent contact during the folding operation; After'the upper pcst has been folded, bolt 12 is retracted and then lower post 5 is folded i ponrest 2 2 while simultaneously, tube 23 is nioved along rail 26, and rod 24 is telescoped so that in this way all the parts resume the position shown in full lines Fig. 1.
