`ladder Bmaybe turned on itsy fulcrnm and raised on its`carriage into either a .vertical or anincli-ned position.

f `A second ladder, C, is placed within the main ladder B, and is supported by it, so as `to be capable of beingslid ormoved longitudinally relatively to it,projecting or dangeplates round ol the said ladder C carries a recessed toothed shoulder, k,and furthermore, the foot of each of the bars of the said ladder G-isfn rr nished with `a socketcd piece, m, for the reception ofateuon, n, of the third or extension ladder,(exhibited at D in Figs. 10 and 11,)Ihis f latterjladder also being constructed with forked braces o oand` with a toothed shoulder, k, applied to it, as shown in the drawings. Furthermore, in order to sustain the fire-ladder apparatus laterally, it may have shores or struts E" E', which may be .hinged or jointed to the upperspartot' the main lad der B, and made to project therefrom and rest upon the ground when the apparat-us is in use;

In order toeii'ect the raising of the ladder C within and relativelyto the ladder B, we

apply tothe said ladder B an endless chain or fbelt and the lifter, the latter will .pass or be drawn out of the recess of the shoulder lc and the ladder C, and will be canghtland retained in position by a spring-pawl, p, affixed to the ladder B, and made to enter a notch, q, properly formed in the rear side of one of the bars of said `ladder,(),`sueh notch being exhibited in Fig. 1 by dotted lines..

Incase it should be desirable to produce a lfurtherupward elevation of the ladder C, th(

` thirdladder, D, is to be first` applied to if i t" serving to maintain Vthe ladder. (l` against the rounds of theladder B. The lower and within the ladder B. In making this ap- -plication the tenons nnof the ladder D are to be inserted within the recessed partsmm, and .so as Ato cause the forked bars o o to receive into their'notches and to straddle the lower @round or foot-bar of the ladder C. This having been accomplished,the liftertooth L, after having paed downward toward and around the toothed wheel G, will be caused to enter,

the-recessed shoulder k2 of the third ladder, D, and by pressure against the same will raise it and the second ladder, C, simultaneously until such lifter-tooth L shall be raised up to the miler H, when it will pass ont of the said part k, and theladder D will be caught and retained by the spring-pawl p taking into anotch, g, formed in said ladder, as, shown in Fig. 11. This third ladder, D, may also be supplied at its foot with socket-pieces, by which another such ladder may be applied to it. Thus any number of such ladders may be joined to one another and with the ladder C, so as to enable it to be projected to any desirable height.

We apply to the ladder C a hooked frame or window-breaker, L', formed as .shown in the drawings, it being hinged to the ladder so as to be capable of being moved in a vertical direction, so as to fall against and break through a window when circumstances may require it to be employed for such purpose. In this. casej the hooks r r of the windowbreaker will pierce the panes andbreak down the sashes-of such window, and by catching on the sill will hold the upper part of the said ladder apparatus hooked to a building when on re. 'lwo ropes or chains, s t, are attached to the said window-breaker, one of them being led therefrom toward and through the upper part of the ladder C, and thence down to one of two windlasses, u v, placed upon a horizontal shaft, M, the same being arranged as shown in the drawings. The outer rope or chain, t, is led downward and attached to the other windlass. This latter windlass is fastened firmly to the shaft M, so as to be movable therewith. Furthermore, the shaft M has another shaft, N, underneath it, both shafts being supported by the frame A. On this latter shaft are placed four other wind'lasses, w ai y z, so applied to it as to be capa-ble of freely rotating thereon. The two shafts M and N are connected by gears a b', so that one may be revolved by means of the other.

We would remark that each of the windliisses o, w, and z'is what we term a reversible windlass or pulley, it being so applied to its shaft as to be -capable of being drawn endwise oi the same and reversed or turned end for end, and so replaced on the shaft. There is a notched projection, c', applied to each end of the windlass or pulley '0,it being so constructed as to enable a key, d', to pass through it and the shaft for the purpose of locking the windlasspnlley v to the shaft. Furthermore, there is such a notched projection c and key d applied to the shaft N and each of its outermost windlasses or pulleys, io

e, the inner end of eachof said pulleys being.-

formed with a sqnareftenon, to enter acer responding recess, g', forme in the adjacent end of the adjacent windlass. :i: or y, which is furnishedwith handles h h', radiating from one of its heads, as shown in the drawings, and particularly in Fig. 13, which is an end view of the said vwindlass. I

The window-breaker L carries a horizontal rocker shaft or frame, O, which turns in a vertical plane, and is slotted or formed wlth a recess, h, to enable a stream-pipe, i, to extend through and turn ,horizontally in it. Two arms, k k, extend at right angles to and in opposite directions from the frame O, as shown in the drawings. From these arms two chains or ropes, Z m', extend. Further'- niore, there are two other chains or ropes, n o,which are afxed to the front part of the stream-pipe i, and pass through the recess h and against pulleys or guides p' p.

All four ropes or chains, l m no', arc led forward through the ladder C, and thence downward. A. hose, P, proceeds from the stream-pipe backward through the ladder C, and thence downward, as shown in the drawings. By means of the four ropes or chains Z' m n o the stream-pipe may be turned so as to point either to the right or left, or upward or downward, as circumstances may require.

The windlasses u'v afford the means of working the ropes or chains by which the windowbreaker can be elevated or depressed, in which case they are to run in opposite direct-ions around the said win'dlass. With respect to the windlasses w w y z, they are for operating the ropes or chains Z mn o', which lead, respectively, to such wndlasses, two ropes being cai-- ried to one pair, while the other two ropes are led to the other pairof them. While arranged for working the stream-pipe each set of its ropes or chains winds in opposite directions about its two windlassels-that is, while one rope wi nds in one direction about its windlasr,

the other is wound in an opposite directioi;v

about the other wiudlass, vand thus, by turning the two windlasses in either direction, one rope will wind on one windlass and the other rope unwind from the other windlass. Consequently, by means ofthe two sets of handles of the windlasses,an individual will be enabled to impart any desirable direction to the streampipe-that is, he can move, it either up or down or s'idewise, either to the right or lei, and thus direct a stream of lwater from it into any part of a bnilding,into a window of which the pipe may enter.' It should be mentioned, however, that under such circumstances cach pair of windlasses wx or yz will be locked together and free to revolve on their shaft N without turning it. Now, if each reversible windlass or pulley be removed from its shaft and next turned around and again applied to theshaft,so as to bring next to its fellow windlass that face or side of the pulley which before was farthest from it, we shall have the in one direction. l Onthe shalt-keys being, restoredto their places it willhefonnd that the windlaescewill `beolockedto theirshafts M N that when the lower shaft isgput. inlrevolution by power applied to its Iwindlass-handles the other sbaftwll hcirevolved-` Under these sin; `wirinfila-sees"inayfbe either` wound up or let ont eimiiltaneously `as lth'e auxiliary ladder or ladders arebeing either raised orllowered;
