Application filed April 25, 1901. Serial No. 5,7,491. (N0 model.)

designed to be used by firemen at fires for the combined purposes of rescuing persons from burning buildings and aiding in extinguishing the fires.

The object of the present invention is to produce an apparatus which shall be eliicient and reliable in its operation, easily and con veniently handled, and at th'e same time shall be compact when not in use, so as to permit the same to be readily housed.

The invention consists, first and essentially, in the combination, with a truck, of a folding tower mounted thereon, means for elevating and lowering said tower, means for sustaining the same in its elevated condition, an elevator in said tower, and means for operating said elevator.

Secondly. The invention consists in the combination, with the truck and the folding tower mounted thereon, of a hose-reel carried on said truck, and means for hoisting and lowering the hose in the tower, and, furthermore, the invention consists in the novel details of construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

Similar characters of reference indicate corresponding parts. i

A and A represent the front and rear running-gears, respectively, of the truck, upon which is supported a platform 13.

The folding tower comprises two sets of lazy-tongs G O, which are disposed at oppositesides of the platform and are connected by a plurality of pairs of transverse rods a a, and on each rod of the lowermost pair is j ournaled 8o apair of rollers b b. By said rollers the tower is mounted on two pairs of tracks 0 c, secured to the top of the platform 13. To the sides of the platform adjacent to the respective tracks are secured verticallydisposed plates d d,pro-

vided with longitudinal slots e e, in which the outer ends of said lowermost rods a a travel, which slots serve in the attachment of the tower to the truck, but particularly to guide the lower ends of the laz *-tongs in their 00 A movement.

f denotes the main shaft of the tower elevating and lowering mechanism, which shaft extends transversely over the platform and is journaled in suitable boxes 9 g, secured to 9 5 said platform. Adjacent to the shaft f and parallel thereto is an auxiliary shaft 7L, journaled in boxes '6 71, secured to the platform.

To each end of the main shaft f is secured a gearj, and to each end of said auxiliary 10o shaft is secured a pinion 7a, which pinions mesh with the gearsj The main shaft is also provided with a pair of pinions Z Z, each of which meshes with a pair of horizontal shown in Figs. 1 and 3.)

racks m m, disposed above and below the pinion, respectively, and connected loosely to the lowermost rods a a of the lazy-tongs, as indicated at n'nand more clearly shown in Fig. 5.

To each end of the auxiliary shaft h is attached a hand-crank 0 for turning the same, and thus imparting movement to the aforesaid racks and pinions, whereby the lowermost rods a a are moved toward and from each other, thus elevating and lowering the tower.

'19 p denote small rollers which bear on the racks m m for the purpose of maintaining the same in mesh with the pinions Z Z, which rollers are preferablyjournaled on posts q q, secured to the platform B.

To the main shaft f is secured a ratchetwheel r,'and to a support .9 on the platform is pivoted apawl t, engaging said ratchet-wheel, whereby said shaft is prevented from turning back when the tower is being elevated. Said pawl and ratchet-wheel serve also to temporarily sustain the tower in its elevated condition2'. 2., until the jointed braces u u and o 1;, connected to the tower, have been straightened, as will shortly be described. The joints of said braces u u and o 'v consist of hinges, (indicated at 1 and 2, respectively,) as clearly shown in Figs. 1 and 3. The braces to u are arranged in two pairs at the front and rear of the tower, respectively. Each pair is inclined toward the tower and is pivoted at its lower end to a transverse rod w, secured in posts. fastened at the corners of the platform B and pivotally connected at the upper end to one of the transverse rods a, which rods connect the upper ends of the lowermost pairs of levers of the lazy-tongs, as clearly shown in Figs. 1 and 3 of the'drawings. The braces '22 r; are disposed in vertical pairs on the front and rear of the tower and extend from the top' of theinclined braces to u to the top of the tower and are pivotally attached to the successive pairs of transverse rods a a, connecting the two sets of lazy-tongs. (Also clearly The lazy-tongs are strengthened and stiffened by rods yy,applied in the well-known manner, and I also prefer to provide the braces with suitable devices for strengthening the same. (Not shown.) 2 represents a supplemental jointed brace,

I wh'ich is pivoted at its lower end to one of the lowermost rods a and at its upper end to the rod a next above and aids in sustaining the tower in its elevated condition.

Each pair of vertical braces'v o is connected at the joints by a transverse bar a, and extending at right angles from said bar is an arm 3, provided with an eye Z) at its inner end, and each brace of the'inclined pairs has attached to it an inwardly-projecting arm 0, provided at its end with an eye d. (See Fig.1.)

On the lower sections of each pair of inclined braces is journaled a transverse shaft e, to which is secured a drum f. To each of said drums is attached one end of a cable or ropeg, which cables pass freely through the shown in Fig. 10.

aforesaid eyes I) and d and are attached at their other ends to the topmost rods a a of the tower. The shafts e of the drums are each provided with hand-cranks h h for turning the drums, whereby the cables are tightened orloosened, so as to straighten the braces after the tower has been elevated to sustain the same and to relax the braces, so as to permit the tower to be lowered. To maintain the cables g g tight, I provide the shafts e 6 with ratchet-wheels z" i and pivot-pawls jj to the traces u, which pawls engage the ratchetwheels to prevent the drums from unwinding.

B B denote two chain ladders which extend from the truck to the top of the tower and are disposed parallel and between the braces an and o e. Said ladders are fastened at their lower ends to transverse rods 7c k, secured to the lower ends of the braces u u, and are fastened at their upper ends to the aforesaid topmost transverse rods a a of the tower. Thus by reason of said ladders being flexible the operation of the tower and braces is not interfered with.

On top of the tower is mounted a jointed metallic frame 0, which may be of any suitable construction and is pivotally connected to the topmost rods a aof the tower, as clearly shown in Figs. 1, 2, and 3 of the drawings.

D represents the elevator, which is disposed in the tower and is operated by means of a pair of cables or ropes Z Z and constitutes the fire-escape. Said cables Z Z are attached at one end toadrum m, mounted on atransverse shaft 01, journaled in brackets q g on the underside of the platform B, and they extend under wheels or rollers r r, suitably pivoted on the under side of said platform and up through openings 3 s and t t in the platforms B and 0, respectively, which latter is supported on the platform B by means of posts 19 p, as shown in Fig. 8 of the drawings. The said cables extend from the openings over pulleys u it, fastened to the frame 0 on top of the tower, and are attached at their other ends to a horizontal bar o, secured to the top ofthe elevator. lVhen the tower is in its lowered or folded condition, the elevator rests upon the supplemental platform 0, as shown in Fig. 2 of the drawings. Said elevator drops by gravity and is controlled in that respect by a brake comprising a wheel 21;, fastened to the aforesaid shaft n, and a flexible metallic band so, embracing aportion of the periphery of said wheel, which band is rigidly connected at one end to the platform B, as indicated at y, and connected at its other end to an operating-lever a, as shown at (1 The said operating-lever is pivoted to the platform B, as indicated at W, and is provided with a vertically-disposed coiled spring c which is connected at its lower end to the band-attaching end of the lever and at its upper end to said plate (1, which spring aids in holding the band into frictional contact with the wheel 10, as clearly The elevator is provided with a pair of vertical guide cables or ropes IIO 5 on the same.

10 formed on posts fastened to said plat- 9 form, as clearly shown in Fig. 8 of the drawings. Said drums g g are provided with suitable means for turning the same so as to tighten the cables e 6 and to maintain the same tight the shafts h h are provided with ratchet-wheels 15 k which are engaged by pawls or dogs Z P, pivoted to the arms 21 The elevator is provided with a verticallyswinging platform m pivoted to the floor thereof, which platform is thereby adapted to be placed in position to allow persons to walk from the windows or roof of a building to said elevator. To sustain the platform in said position,lprovideapair of longitudinally- 2' 5 slotted arms n 073, pivotally attached to the platform and to the elevator bymeans of pins 0 0 projecting on the inside of said elevator. The said arms are adapted to slide on the pins, whereby the platform can be swung to 0 vertical position, as shown by dotted lines in Fig. 8, so as not to come in contact with the tower when the elevator is being dropped. I prefer to provide said platform with side rails 19 13 which afford safety to persons walking The elevator is provided with a door g on the side opposite the platform to allow persons brought down in the elevator toleave the same. 7 It will be understood that additional doors maybe provided on said ele- 0 vator, if desired' Bymeans of the aforesaid ladders B B firemen can quickly and easily climb to the elevator, when it is raised, in case help is required by persons entering the elevator from a building.

5 I prefer to provide the two sets of lazy-tongs with transversely-disposed coiled springs 1? 1- as shown in Figs. 1 and 2, which springs aid in elevating the tower.

D is a reel mounted on a transverse shaft F, j ournaled in brackets 10 a on the rear end of the truck, on which reel is carried the usual fire-hose o Adjacent to the reel is a windlass D to which is attached one end of a rope.

or cable 10 which extends through an eye 10 on the platform and over a pulley w, fas-.

tened to the aforesaid frame 0, mounted on top of the tower. The other end of said rope or cable is intended to be attached to said hose, whereby the same can be hoisted in the tower, and thus be readily carried into a windrawings.

Incase the ground on which the truck stands while the tower is elevated is such as to cause the tower to lean to either side I employ a leveling device which operates to carry the said tower into erect position. Said device is illustrated in Figs. 12, 13, 14, 15, and 16 of the drawings and comprises a horizontal bar or beam 0. secured detachably and longitudinally adjustable to the under side of the platform B by means of suitably-shaped irons b firmly bolted to the platform. Said bar projects from the side of the truck, and to its outer end is hinged a vertical arm 0 as shown at (1 which arm is provided with vertical guides c c" in which is disposed a post f bearing on the ground. The arm 0 is provided also with a bracing-rod g which is pivotally connected to the arm, as shown at 71. and at its opposite end to a shoe i which slides in a slotted plate or track f on the under side of the bar a and through said shoe passes a set-screw which engages said plate to sustain the arm in its vertical position. 'When the leveling device is not in use, the arm is to be folded against the under side of the bar and may be held in the latter position by any suitable means, such as a hook, (not shown,) and the bar is to be detached and placed upon the platform.

To the back of thepost f is secured a vertical rack k which meshes with a pinion Z secured to a transverse shaft m passing through and j ournaled in the arm 0 and to said shaft are attached hand-cranks g for turning the same, whereby the said arm is made to slide vertically on the post, thereby leveling the platform to carry the tower to erect position. To retain the platform in its level position, I provide the shaft m with a ratchet-wheel 0 which engages a pawl 1J3, pivoted to said arm.

On the front end of the truck is provided a leveling-gage the detail construction of which is shown in Fig. 17 of the drawings, and it comprising a casing w, in which is suspended a pendulum I), provided at its lower end with a point 0, adapted to register with a similar point (Z below it.

A represents a jumping-net which is hung on a frame e pivotally connected to a horizontal bar f which is locatedat one side of the tower, whereby the not can be swung up against the tower when not in use. Said bar f is formed with two longitudinal slots 9 g, which receive the ends of one of the pairs of transverse rods a a, and to the ends of said rods are applied nuts h M, which securely hold the said bar on the rods, said rods sliding in the slots when the tower is being, elevated or lowered, as shown in Figs. 1 and 3. I prefer to provide the net with a safety-rail 2' which is secured to the aforesaid bar f The net is sustained in horizontal'position by means of ropesfif, fastened to the outer edge of the frame 6 and to the tower at any suitable part. Said ropes are provided with coiled springs a e at their attachment to said tower,

whereby the frame-will yield when a person strikes the net, thus overcoming all jar and strain.
