PATENT JAMES PULLAR, OF HARTFORD, CONNECTICUT.

SPECIFICATIQN formingpart of Letters Patent No. 669, 180. dated March 5, 1901.

Application filed May 14, 1900.

To all whom, it may concern.-

Be it known that I, JAMES PULLAR, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in a Combination Fire-Escape and Water-Tower, of which the following is a specification.

My invention relates to portable towers for fire-department or other use; and it has for one object the provision of a tower of that kind which is capable of vertical extension to the desired height and the platform of which may be lowered to bring the same and its connected parts to a position where they can readily be transported without undue swaying or vibratory movement.

A further object of the invention is the provision of an extensible tower having a platform which may be adjusted to bring the firemen or others thereon to any desired angular position with reference to a building or other structure.

A further object of the invention is the provision, in connection with the rotatable platform of a tower, of a ladder or slide which may be thrust laterally from the tower into a window of a building or onto an abutment thereof, and thus serve the purpose of a bridge over which persons or property may be carried to a position of safety.

A further object of the invention is the provision of means for lowering rescued persons or property from the platform of the tower or for elevating firemen or appliances used by them thereto.

A further object of the invention is the provision of improved means and mechanism cooperating with said means for extending the platform of the tower to the desired elevation.

Portable towers as now constructed are capable of extension only to a certain height, and are consequently limited in efficiency, and if made of the proportions necessary to reach abnormal heights they are so cumbersome and bulky that their use is almost prohibitive; but with my invention this defect is obviated and a strong well-braced structure capable of any desired vertical extension is produced and one which when lowered to its normal height is compact and serviceable and can readily be transported.

serial No, 16,551- (No model.)

In the accompanying drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a plan view,part of the platform being broken away to show mechanism below said plat form. Fig. 3 is a plan view, part-lyin section, of one of the frames employed in connection with the elevating-bars. Fig. at is a side view of a set of friction-rolls for elevating and lowering the vertical bars or pipes. Fig. 5 is a plan view of a set of said friction-rolls, showing the bar to be elevated in section. Fig. 6 is a sectional View of the platform and mechanism carried thereby. Fig. 7 is a detail view of the extension-joint of the vertical bars or pipes, and Fig. 8 is a view of said joint before two bars have been coupled together and passed through the frame.

Similar characters designate like parts in the different figures of the drawings.

Referring to the drawings, the numeral 5 designates a vehicle of any desired kind (shown as a Wheeled truck) having a platform 5 and

vertical standards

6 and 7, to the upper portions of which is secured a frame 8, having side bars 8 and end bars 8 said frame being at its top of a general rectangular outline. Journaled in bearings of this frame are sets of shafts (designated, respectively, by the

numerals

9, 10, 11, and 12,) the sets 10 and 11 being located above the sets 9 and 12, and each set consisting of two intergeared shafts, as will hereinafter be described. Near one end of each of these shafts a grooved friction-wheel is mounted, the friction-Wheels of the shafts 9 being designated by 9 and 9 those of the shafts 10 by 10 and 10 those of shafts 11 by 11 and 11 and those of shafts 12 by 12 and 12 At their opposite ends the shafts just mentioned are provided with sets of intermeshing gears, preferably of the spur variety, although other kinds may be used, (designated, respectively, by the numerals 13 13, 1-1 14, 15 15, and 16 l6,) and on the ends of the

shafts

9, 10, 11, and 12 large gear-wheels (designated, respectively,

of which is shown in Fig. 4,) the tension of said springs being regulated by screws or equivalent devices 28.

Coming now to another part of my invention, the numeral 29 designates tubular bars which are stored on the platform of the vehicle in readiness for use, and at one end each of these bars is'slitted, as at 29', and the opposite end is provided'with a reduced portion or tenon 29 adapted to fit into the tubular slitted end 29' of another "bar.

Constituting a part of my elevating apparatus is a tower-platform 30, and this platform is surrounded bya guard-rail 31, which, in addition to subserving its usual function, also may be employed as a convenient rest for hose in use by firemen on the platform in case of a conflagratio'n. Mounted for rotative movement in this platform isa turntable 32, connected to which is a gear-wheel 33, the latter being operated by a pinion 34, attached to a shaft, which maybe actuated by a hand-wheel or other device 35. By the means just described the turn-table32 may be rotated to bring the firemen or other persons thereon in the proper position for directing a'stream from the hose to the desired part of 'the building. Mounted in a groove orgu ideway of the turn-table is a ladder or slide 36, having a rack 37 on its side, which is in engagement with a pinion 38, carried by a shaft actuated by a hand-wheel 39, and by means of this device the truck carrying the towecand platform may be located at a considerable distance for instance, across the street from the buildin gand the ladder or plank be 'thro wn across the intervening space and made to engage with a'window-sil-l or other abutment, thus serving as a 'means for rescuing personsor property. By means of the rotary adjustmentof the turn-table described any desired angular position ofsaid ladder or slideorof a line of hose carried by the turn-table may be effected, and thus the device may be put to the desired use in rescuing persons and property and in extinguishing fires. Oeutrall'y the turn-table is provided'with a large opening 40, and adjacent to said opening a standard 41 is erected, upon which is journ'aled a sheave 42. Over this sheave passes the rope 43, which is connected at its lower end toa basket, seat, orothersuitajble device 45, by which firemen oi-their assistants 'may be elevated 'to the platform '30aud persons and property'ma'y be lowered therefrom,

purpose of reaching buildings of moderate height, rods 29 are inserted between the friction-rollers 9 9 10 10 11 11 and 12' 12 and the gearing foractuating said rollers may be started in motion by turning the crank 24. As these rods are elevated they pass loosely through fittings of a frame, to be hereinafter described, and their upper ends are inserted in sockets on the under side of the platform 30. This frame is designated in a general way by the numeral 46, (see Fig. 3,) and is preferably formed of rods or pipes 47 47 coup ed together-at their ends. Adjacent to each of the end bars or pipes 47 the side bars or tubes 47 are provided with tubular fittings 48, through which the bars 29 are passed, andv when it is desired to extend the height of the platform 30a'nd its turn-table 32, as exigencies may require, "a second set of bars 29 is introduced between the friction-rollers with the slitteden'ds 29thereof uppermost, and this set is advanced by said rollers until the ends thereof are inserted 'within the fittings 4'8 and over the tenoned ends 29 of the first lhe two sets of 'bars are then rigidly clamped together by rods 49 49, which are fitted for 'reciprocatory movement in the tubular side bars 47 of the rectangular frame 46 and the ends of which bear against the slitted ends of the bars 29. For actuating these rodsa'ny's'uitahle device or devices may be employed, and I have shown for this purpose a cam or eccentric 50, having a handle 51, said'cman'or eccentric being pivoted within a sleeve 90, fitted over the side bars 47, as shown in Fig. 3. By turning this cam or eccentric by means of the handle 51 the surfaces thereof are caused to act against the rods 49 49' and drive themforward forcibly against th'esplitends 29' of the bars 2?),causi'n'g said ends tightly to clamp and bind the teno'n'e'd'ends 29, of thefirstse't of bars.

In'order 'th'at all four of the split ends of the bars to be added to the 'fi rst set of bars in extending the height of the tower may be operated upon, I preferably connect thehandles 51=of the cams or eccentrics 50 by'a cord 52, passing'ove'r pulleys "53, (see Fig. 3,) so that when'o'ne cam is actuated the other will also be turned and the rods or bars 49 49 will be caused simultaneously to act upon the slitted ends 29. After this connection has been effecte'dthe platform 30may be'eleva'ted for another distance equaling about the length of the set of bars added, and so on until the desired elevation is attained.

It is of cou'rseto he understood thata serieso'f frames 46 is to be carried by the vehicle and that these are to be coupled on to the pipes orbars 29, as circumstances may requ re.

ln Fig. 1 the bars 29 are shown separated at intervals, and three of the frames 46 are By the means described an'y'd'esiredelevat'ion of the .platform 30 compatible with safety and conven-.

ience may be obtained and the frames 46 IIO and their attachments act as braces rigidly to connect the bar-sections 29 and also to prevent them from vibration or lateral movement.

Any convenient means may be employed for preventing back action of the frictionrollers when in contact with the bars, and I have not deemed it necessary to illustrate such devices, although of necessity some suitable stop must. be adopted for preventing the gearing from turning backward and permitting the descent of the platform 30 and the connected bars 29.

My invention is not limited to the precise details illustrated and described, for the gearing for actuating the friction-rollers may be variously modified Without departure therefrom, nor is it limited to any specific device for rotating the turn-table on platform 30 or for projecting the slide or ladder 36.

If desired, when the bars directly in contact with the platform are lowered to the limit of their downward movement the platform may be lifted off the ends of said bars and stored on the bed of the vehicle, the invention not being limited to any particular way of removably connecting said bars and platform.
