SPECIFICATION forming part of Letters Patent No. 519,234., dated ltf ay 1, 1894.

Application filed November 30, 1892. Renewed October 6, 1893. Serial No. 487,392. (No model.)

To all whom, it may concern.-

Be it known that LE iLIo CARDARELLI, a citizen of the United States, residing at Sumter, in the county of Sumter and State of South Carolina, have invented a new and useful Fire-Escape Truck, of which the fol- This invention relates to fire-escape-trucks; and it has for its object to provide certain improvements in machines of this character which can be readily and conveniently trans ported from place to place for the purpose of gaining access to the upperstories and roofs of occupants and the saving of property.

Tothis end the invention primarily contemplates an improved portable truck, carrying shooting track sections, means for adj usting and extending the same, together with necessary equipments and appurtenances for providing a safe car-way from one end of the time also aiding the firemen in their work.

With these and many other objects in View, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination,

fully described, illustrated, and claimed.

In the accompanying drawings:Figure 1 is a perspective viewof the truck in position for use with all of its track extended. Fig. 2 is a vertical longitudinal sectional View of the apparatus in the position shown in Fig. 1. Fig. 3 is a side elevation of the apparatus in position to be transported from place to place. Fig. 4 is a vertical sectional view of the apparatus through one of the vertically adjustable racks, with the apparatus in its extended position as illustrated in Fig. 2. Fig. 5 is a sectional view on the line 55 of Fig. 3. Fig. 6 is a detail sectional view of the car hoisting dru m-brake. Fig. 7 is a sectional view of the car. Fig. Sis a perspective view of the inclined wheel lever. Fig. 9 is a detail sectional view of the upper end of the outermost track section. Fig. 10 is a detail sectional view of the sliding joint of the innermost extension section with the pivot track section. Fig. 11 is asimilar View of the connectionof the ground track section with the pivot track section.

Referring to the accompanying drawingsgA represents a truck frame constructed and braced in any suitable manner and carried upon the wheelsB, which provide means for 1 ends of the centrally depending supporting arms I), is a circular floor or platform 5', upon which is supported for rotation the revoluble standard frame O. The revoluble standard frame 0, is provided at the lowerend thereof with the ,pivot stud 0, working in a central perforation. in the platform I), so as to provide means for holding the said standard frame steady in its rotary movement, and at the base of the standard frame is arranged the circular base plate 0, upon the under side of which is mounted the small anti-friction rollers 11?, which travel over the stationary platform suspended from the truck, in order to ease the standard frame from friction and allow the same to be turned easily inside of the truck. The revoluble standard frame 0, comprises the opposite tubular guide standards 0 connected at their upper and lower ends, and said tubular standards are encircled at or about the plane of the truck frame A, by the roller ring c, towhich ring are attached the anti-friction guide rollers c ,-adaptedto work over the adjacent guide ring a, secured stationary to the center of the truck frame, so that the entire standard frame will be heldsteady in its vertical position within the truckframe when being turned in any di- (of the sliding bolt 0 mounted on the roller ring 0 and adapted to be thrown in engagement with a suitable keeperor loop 0 several of which are secured'at suitable points on the top of the truck frame A. The opposite tubular guide standards 0 accommodate the opposite sliding vertically adjustable rack bars D. The rack bars D, which move withtoo in the opposite tubular guide standards are connected at their upper ends by the upper cross-bar d, which forms the movable fulcrum for the extension track sections to be hereinafter described, and it will be observed that the said rack bars D, carry atsuitable points within the tubular guide standards small anti-friction rollers d, which work against said guide standards, while said guide standards also have near their upper ends corresponding friction rollers 61 which bear againstone face of the movable rack bars, so that the movement of the rack bars is greatly eased, owing to the disposition of said rollers.

In order to counterbalance the weight of the vertically adjustable rack-bar frame and the devices carried thereby, I employ the counter-balancing Weights (1 mounted to slide in the opposite guides d secured at opposite inner sides of the tubular guide standards, and said weights (1 are suspended from one end of the weight ropes d passing over the upper guide pulleys d, arranged at the upper end of the'standard frame, and connected at their other lower ends to the lower inner ends of the racks, or at least to the center of the lower cross-bar d, connecting the lower ends of the racks. It will therefore be readily seen that as the rack frame is adjusted vertically, the counterbalan cin g weights necessarily drop or lower, and vice versa. The opposite tubular guide standards are provided at one side of the samewith the bearing lugs E, in which is journaled the transverse raising and lowering shaft 6, carrying the opposite pinions c, which project through slots in one side of the tubular standards and engage the teeth of the rack bars, so that as the said shaft is turned, the back bars are raised or lowered as desired. At each end of the shaft 6, outside of the bearing lugs, are mounted the hand-wheels e which are easily controlled by means of the firemen on the truck to raise and lower the rack frame, but one of said wheels may be a fly-wheel, while to the other may be connected any suitable devices for driving by means of motive power. After the rack bar frame has been elevated to any height desired the same may be held in such adjusted position by means of a stop pin 6 passing through any one of the perforated spokes of the wheel, or other equiva lent means to secure the same result. The upper end of the rack-bar frame moving within the tubular standard frame forms an adjustable fulcrumed or pivotal support for the pivoted track section F. The pivoted track section F, comprises the opposite angular or angle iron railsf, having the inner face grooves f, and connected at their-ends, and an intermediate point by the bracing bridles f the central one of which is hinged or pivotally connected to the upper cross-bar d, of the rackbar frame, as at f so as to. pro vide means for allowing the said track section to be raised and lowered from the ground, and when raised from the ground and resting in its approximately horizontal position in a line with the disposition of the truck, out of use, the central bridle of said track section rests against the stop shoulders f secured to the top of the rack bar frame and preventing the track section from tilting to the opposite side of the machine. of said track section rest directly on top of said stops, which also form supports therefor. The fixed pivoted track section F, accommodates the lower or inner ground track section G, and the outer telescoping extension sections H, to be presently referred to.

The ground track section G, comprises the opposite angular rails g, corresponding to those of the fixed track section, and embracing and sliding over such rails, and the rails of the ground track section G, are also connected by the bracing bridles g, so as to form the track, and it will be readily understood that when the tubular standard frame is turned around in its proper position for use, and the pivoted or fixed track section .tilted toward the ground, the ground track section G, can be drawn out from the fixed track section until its lower end touches the ground at any point desired, according to the tilt or inclination to be given to the entire track.

To hold the lower end of the ground track section, when extended,firmly to the ground, I employ the sectional ground locking bar 9 The sectional locking bar 9 comprises the sliding members 9 having a series of adj ustment perforations g which receive a locking pin g holding the same in any adjusted position. One of said members is pivoted at its inner end to the lower end of one of the arms I), of the truck frame, while the other member is provided at its outer end with a locking tongue 9", adapted to engage the socket 9 on the lower oroutermost bridle of the ground track section. WVhen the apparatus is not in use, the locking bar can be folded back against the side of the truck frame, and held thereto by means of a suitable sleeve, Z, slipped thereover and overone of the keepers or loops 0 When the ground track section is distended from the lower end of the pivoted track section, the adjacent bridles of said track sections are connected by means of a locking strap Z, which strap when tightened serves to stiffen the entire track, so that the same will not sag and sway while the apparatus is in use. The outer telescoping extension sections H, are adapted to slide one within the other and all be nested inside of the rails of the pivoted or fixed track section F, and may be in any number desired according to the height which it is necessary for the machine to reach. The

telescoping outer sections H, comprise the opposite rails h, identical in construction with the rails of the other sections described, and which are also connected by the cross-bracing bridles h, serving to strengthen each track section, and it will be noted at this The rails IOC point that the rails of the sections which are extended beyond the upper end of the pivoted or fixed track section, work inside of the face grooves or top and bottom sides of the rails of the next lower section, this arrangement providing means whereby the outer telescoping sections can be nested within the single pivoted or fixed track section within about the compass of a single section.

The outer or upper end bridle of the fixed or pivoted track section and the corresponding end bridle of the first extension section H, or all of the extension sections H, except the last outermost section, if there are more than illustrated in the drawings, are provided with the inwardly extending stop fiangesl, which are struck by'the lowermost bridle of the extension sections when the same have been extended to their limit, so as to prevent the several track sections from becomingdis,

connected. The upper end bridles carrying the stop flanges also accommodate the pulleys or guide wheels J, over which are designed to pass the operating wires K, of the several track extensions H. The operating wire K, which operates the innermost of the track sections H, has one end thereof connected to the innermost bridle of said section, and is passed over the pulley or guide wheel at the outermost end of the pivoted or fixed track section, while the other end of the wire is secured to the winding drum L. The winding drum L, is loosely mounted on the stationary shaft M, secured at its ends to the opposite arms m, which are secured to and at one side of the tubular guide standards of the revoluble standard frame. The drum L, which is loosely mounted on the stationand therefore shoots or extends the said in nermost track section from the pivoted track section. When this track section has been extended its full length, the winding drum L, is held firm by means of a sliding bolt catch Z mounted to slide at one side of one of the tubular guide standards, and be projected within any one of the hollow hand spokes N, thereby locking the drumand preventing the same from rotating, so as to hold the track section in its extended position. If found necessary, or whenever desired the other extension section or sections can be extended in a similar manner from the last extension section just extended, by the same means just described, and the operating wire there for is connected at one end to the innermost bridle of the section to be extended, andpassing over the pulley or guide rollerat the outer or upper end of the section 111 which it,

slides, is passed to an operating drum L,

may be any number of the extension sections 1-1, which are to beextended from the pivoted or fixed track section, so that the apparatus can be accommodated to the very tallest buildings,and according to the number of such extension sections H, the windin g drums and the operating wires winding thereon must necessarily correspond in the same number, for there is a single drum and a single operating wire for each of the extension sections. Now it will be readily seen that when the several track sections, have been extended at the incline desired and to the height desired and locked at theground by the means described and stiffened by means of the looking strap referred to, the track is ready for use. The several track sections in this position guide and support the escape car 0. The escape car 0, is constructed of suitable material and in a suitable shape, so that the main body the bearings 0, which receive the car axles 1P,

which carry on each end thereof the guide wheels or rollers 19. The said guide wheels or rollers workinside of the innerside grooves of the angle rails, so that as the car travels up the track, the said rollers or wheels hold the same firmly to the track and effectually prevent the possibility of the same becoming displaced, and to assist in guiding the car and holding the same to the rails I further employ the short depending guide arms 10', which project from opposite sides of the same and overlap thesides of the rails. The car 0, is of course provided with suitable grasps or holds for the persons carried therein and with a suitable door Q, for entrance and exit, and in order to provide means for carrying the hose up to any point desired, the same is provided with a hose roller guide R, at the lower end thereof and a nozzle hook 0", inside of the same in which the nozzle of the hose can be caught sothat the hose can be carried up with the car in its ascent. ihe car is raised and lowered over the track by means of the hoisting wire S, connected at one end to the body of the car and passing through the entire length of the track to the upper end of the outermost track section, and at such point passes over the guide wheel or pulley s, mounted at said extreme upper end. The hoisting wire S, which passes over the guide pulley at the extreme upper end of the last to the drum or Windlass T. The journals of the drum or Windlass T, are mounted in suitable bearing arms if, secured at one end to the opposite tubular guide stems of the revoluble standard frame. An operating wheel t is connected to one end of the drum shaft nected to the other end thereof in order to.

allow the same to be controlled from both ends. As the drum or Windlass is wound in one direction, the hoisting wire S, draws the car up the track to the top thereof, and by easing the drum or Windlass in the other direction the car is lowered, and the descent of the car is regulated by means of the spring actuated brake shoe U. The spring actuated brake shoe U,is arranged over the rim of the wheel 15, and is secured to one end of the bar u. The bar a, works in the socket 11/, extended from one of the bearings 25, and accominodating a spring M, which normally holds the brake shoe away from the wheel, and said brake shoe is held as tightly as desired onto the rim of the wheel 15', by means of a regulating set screw W,workingthrough a threaded support to, extended from the socket a. At the upper end of the last or uppermost ladder section is arranged the pivoted cap w, which incloses the upper guide roller for the hoisting wire, and also provides a platform at the upper end of the track, and at said upper end of the track is also arranged the guard roller w which serves to ease the upper end of the track from the building. If found necessary to extend the use of the machine beyond the upper end of the track, I will then employ one or more auxiliary ladders X, which ladders are fastened to the body of the car 0, by being passed through suitable retaining loops 00, secured to the car body and having their lower ends held within a receiving pocket 02, secured to the car body, so that when the car is carried to the top of the track, the auxiliary ladder is necessarily carried therewith and is extended its own length beyond the end of the track, thus enlarging the use of the apparatus. It will be seen that when one of these ladders is on the car the persons can be delivered from the windows or roofs of the building into the car as is clearly shown in the drawings.

In order to provide for signaling from the truck to the top of the ladder and vice versa, I attach the alarm bells Y, to the upper end of the track section and to one of the standards of the revoluble standard frame, and to the hammer of each of the bells I attach a signaling cord y. It will be seen that one end of the cord y, is always attached to the hammer of the upper bell, while the other end of the cord is connected to the reel y, mounted loosely on one end of an extension of the shaft e, and held fast on the shaft when desired by means of the nut 11 working on a threaded portion of theshaft. Now it will be apparent that as the track sections are extended the reel will pay out the signal cord, so that when the extension of the track sections is stopped, the reel can be made fast by means of the nut, and the slack of the cord attached to the hammerof the lower bell, and

thusprovide asignal communication between the truck and the upper end of the apparatus. When the track sections are lowered, the slack of the signal cord is taken up on the reel. In case the carriage or truck is put in use on a hill or upon unlevel ground, I then employ the leveler Y. The leveler Y, comprises the opposite connected inclined flanged short rails or blocks Y at the highest ends of which are arranged the stops Y, to prevent the wheels of the carriage from passing out of the same, said leveler being adapted to be placed under the wheels of the carriage which are in the lowest position, so that the entire truck or carriage is placed level or in a horizontal position to hold the apparatus level while in use.

It is thought that from the foregoing description, the operation and many advantages of the herein described fire truck, will be fully apparent without further description, but reference may be further made at this point to the positions of the apparatus illustrated in the drawings. When the machine is not in use and is being transported from place to place, the several track sections are nested within each other, and the car is run to one end of the nested sections and held at such end by means of the drum or Windlass brake referred to, thereby holding the nested track sections in approximately a horizontal position in alignment with the length of the truck or the carriage, the auxiliary ladder X, being hung on suitable hooks at one side of the apparatus as illustrated. When the machine reaches the point of use, the revoluble standard frame is turned or rotated to the necessary position at any angle and locked in such set position as herein described. The rack bar frame is now elevated to the height desired, and the latter sections tilted and extended into position for use as herein specifically set forth. The car is now manipulated as described.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this i11- vention.
