FIRE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 669,492, dated March 5, 1901.

Application filed November 22, 1899. Serial No. 737.914. No model.)

To otZZ whont it may concern.-

Be it known that I, LESTER W. GILL, a subject of the Queen of Great Britain, residing in East Somerville, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Fire Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention relates to improvements in apparatus to be used in extinguishing fires and rescuing people from burning buildings; and the object of the invention is to provide a portable apparatus which can be elevated with despatch near a burning building, so as to form a temporary stage or tower on which the firemen may ascend and elfectively direct water on the burning building, also to provide a fire-escape whereby people may be conveyed from the windows of the building to the said tower and thence to the ground.

The apparatus may also be used in time of war as a military observatory'and in any case Where a temporary stage is required.

The invention consists in the combination of elements and in certain parts of construction entailed inthe combination of said elements to obtain the desired result.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying the various features of the invention, and such a descript-ion will now be given in connection with the accompanyingdrawings, and I attain my object by the mechanism there illustrated, showing such preferred construction, and the features forming the invention will then be specifically pointed out in the claims.

In said drawings, Figure 1 represents a side elevation of the apparatus when folded up for conveyance. Fig. 2 is a sectional View of the hydraulic jacks J. Fig. 3 is a top view of the apparatus when elevated and with fire-escape in position. Fig. 4 is a sectional elevation of the locking arrangement which locks one section to the adjacent one, taken on the line 1 2, Fig. 3. Fig. 5 is another sectional elevation of the locking arrangement, taken atninety degrees to the section in Fig.

The Whole apparatus is mounted on a fourwheel truck W and may be conveyed from one place to another by any suitable power. The apparatus is essentially made up of braced frames or sections S S S S S which telescope, and when elevated these sections automatically lock to one another, and thus form a rigid structure. The sections are elevated by means of a series of telescopic tubes T, placed vertically in the center of the sections. These tubes are fluid-tight and are extended by hydraulic pressure. The first and last of these tubes are connected, respectively, to the first and last sections. The ele- 8o vation of the sections is thus accomplished by extending the tubes, which may be done by means of any fluid-pressure.

The truck W, on which the apparatus is mounted, is provided with springs similar to other fire apparatus and is provided with four legs L. These legs L, on which the apparatus rests when in use, are pivotally connected to the section S at the points Y and Z and in conveyance are folded closely to the sides of the said section, (see Fig. 1,) being held in this position by spring-locks A. When it is desired to raise the sections, these legs L are swung out through an angle of one hundred and twenty degrees and are stayed in this position by the folding braces B. (See Figs. 1, 3, and 7.)

By means of the jacks J, attached to the outer part of the legs L, the apparatus is leveled, and the whole apparatus, including truck, is thus supported by the four legs when in use.

While the sections may be raised by any fluid-pressure, it is most convenient when used in case of fire to connect the fire-engine to the pipe C, which leads into the tubes T. The pipe 0 may have several connections attached to it, so that several engipes may be connected. When pressure is applied by the action of the engine to the tubes T, these tubes extend and raise the upper or last section S which is connected to the upper or last tube. On each of the bottom corners of this section there is a horizontal projection or lug D. (See Figs. 4 and 5.) When this section is elevated, these lugs engage in recesses in the top corners of section S Section S thus raises section 8.

When the sections are closed together, as in Fig. 1, the projecting pins a (see Fig. 5) on the top of section S are held apart by the wedge-shaped pieces G on the top of section S (See Fig. 1.) These pins a are rigidly connected to the bars 6, and the bars 17 are connected to the locking-bars E by the links d, (see Fig. 4,) so that when the pins a are forced apart the locking-bars E are withdrawn. The locking-bars are thus all withdrawn when the sections are closed, as in Fig. 1. Therefore when section S is raised hydraulically by the tube T the lugs D on its lower corners pass freely into the recesses in the top of section S. As section S raises, the pins a in the top of this section become disengaged from the wedge-shaped pieces G on the top of section 6., the wedges G, one on each side, remain stationary, being connected to section S and the pins a are raised up with section 8. The pins a being now free to come together, the springs F force the locking-bars E under the lugs D, bringing the pins 0, together at the same time. Section S is thus rigidly locked to S. In a similar way each section raises and automatically locks itself to the following section, each section being provided with lugs and locking arrangement, as above described. Section S is locked to section S by an operator. This is necessitated since there is no further motion by means of which these locks may be operated.

The sections are lowered by unlocking section S from section S by means of the levers h. (See Figs. 1 and 7.) If the dischargevalve in the end of the pipe 0' (see Figs. 1 and 3) which leads from the tubes T is now opened, the sections S S S S will descend by gravitation. As these sections descend, the wedge-shaped pieces G on the top of section S act on the pins on on the top of section S forcing them apart, thus withdrawing the locking-bars E in the top of section 3*. Section S is thus unlocked from section S In a similar way each section automatically un- S and are attached to weights.

locks the following or telescopic section as it descends.

The standard K (see Fig. 7) is forced out from the center of the tubes T by the same pressure which extends the tubes. The cables M, which stay this standard, are fastened permanently at the upper ends. The lower ends pass through the corners of the section When the sections are lowered, these weights slide down inside the section S and the standard K slides inside the tube T. The drum'and Windlass N are clamped to the standard K after the standard is forced into position. The drum and Windlass serve to raise the fire-escape P int-o position by means of the cable m and to raise or lower the outer end when in position. The escape is raised from inside section S through a hatchway It. (See Fig. 3.)

The fire-escape Pis pivotally connected by a hinged pivot 0 (see Fig. 8) to the side of section S and is thus adjustable in a horizontal as well as in a vertical plane. The sides are pivotally connected by hinges U to the base, (see Fig. 8,) so that they may fold together, and the whole carried inside section S (See Fig. 1.) The sides when in use are pivotally connected at the ends to railings R, which are hinged to the posts Q. (See Figs. 1, 3, 7, and 8.) These railings are constructed on the principle of the lazy-tongs and are connected to the sides of the escape by means of a hinged pivot- X. (See Figs. 8 and 9.) This arrangement allows the movement in any direction of the escape on its pivot 0. These gates also serve to keep the sides of the escape in position. The escape is in the form of a bridge, the sides and base of which are extensible, similar to an extension-ladder. The sides are rigidly constructed, so as to form a support for the base. The extension is effected by an operator on the top of the tower by means of a cable acting through suitable blocks, as in an extension-ladder. Theescapecan thusbeextended and the outer end placed on the sill of the window where it is to be used. After the sections are raised the tubes T serve to conduct water, which may be used to extinguish the fire by means of a hose connected to the outlets H. (See Figs. 6 and 7.) These outlets H are supplied with spherical valves d, which are kept closed by the pressure from Within the tubes 'l and which are opened by the action of the pin 6 in the center of the hose connection f. (See Fig. 6.)

Each section is provided with a floor and two ladders V. The ladders are pivotally connected at the upper end to the sides of the section, (see Figs. 10 and 11,) and when the sections are raised they may be brought into an inclined position and locked. They will thus be inclined for ascent, as is usual. (See Fig. 7.) The locking is effected by means of notches in the bottom of the ladders, which engage with a cross-sill secured to the bottom into engagement with the sill.

of the section. (See Figs. 10 and 11.) The top of each ladder is slotted, so that it may be raised a small amount to bring the bottom (See Fig. 11.)
